The project description, site conditions and our geotechnical conclusions and design recommendations are presented in the text of this report. Supporting data including detailed exploration logs and field exploration procedures, as well as results of laboratory testing are presented as appendices. Our geotechnical engineering scope of services for the project included a site reconnaissance, subsurface evaluation, laboratory testing and preparation of this report. The subsurface evaluation consisted of completing seven exploratory borings (designated B-1 through B-7) across the site and two shallow hand -excavated test pits (TP-1 and TP-2) beneath the existing building. The borings extended to depths of approximately 8% to 14 feet below ground surface (bgs) while the test pits were completed to a depth of 1 1/2feet. Figure 1, the Site and Exploration Plan, presents the approximate locations of our subsurface explorations completed for this project. Appendix A contains a description of our field procedures and the boring and test pit logs. Appendix B contains a description of the various laboratory testing procedures and the test results. SITE DESCRIPTION The project site is located at 21008 - 76JI Avenue West in Edmonds, Washington. The project site is approximately 2.3 acres in size and is developed with the Prestige Care and Rehabilitation of Edmonds facility. The facility is currently vacant, but the building and surrounding pavement and landscaping are still intact. The site is relatively level overall. Plans for the existing structure indicate that the building was designed with conventional shallow foundations and a crawlspace. A few isolated spread footings west of the courtyard were apparently underpinned, apparently due to settlement. We understand that most of the stormwater runoff from the site is conveyed to the stormwater system in 761t' Avenue West and some of the roof runoff discharges to the ground. Non - building portions of the site are covered with asphalt pavement and landscaping. The site is bordered to the north by a multi -family residential development, to the south by commercial development, to the west by single-family and multi -family residential properties, and to the east by 76th Avenue West and multi -family and commercial developments beyond. ZiDDer Geo, Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 Apri122,2014 PROJECT UNDERSTANDING We understand that Prestige Care is planning to demolish the existing structure and construct a new building. The new 43,613 square -foot structure will include a 5,169 square -foot basement under the southeast corner of the building. Main and basement finish floor elevations are planned at 437.00 and 426.33 feet, respectively. The existing main parking area will be fill ed up to about 2.5 feet to create the parking area while the crawlspace of the existing building will be filled with about 1.5 to 2 feet of new structural fill. The new parking lot fill will be supported by approximately 2- to 4-foot tall rockeries. An approximate 7,000 square -foot, below -grade detention vault with 6 feet of storage is planned beneath the main parking area. SUBSURFACE EXPLORATIONS The subsurface evaluation consisted of seven borings (13-1 to B-7) completed across the site and two shallow hand -excavated test pits (TP-1 and TP-2) beneath the existing building. The borings were completed on July 11 and 12, 2013 while the test pits were completed on July 16, 2013. The approximate locations of the explorations are presented on Figure 1, the Site and Exploration Plan. The locations of the explorations were determined by taping from existing site features. SUBSURFACE CONDITIONS Published Geologic Mapping The Geologic map of the Edmonds East and part of the Edmonds West quadrangles, Washington (Miscellaneous Field Studies Map MF-1541, J.P. Minard, 1983) by the U.S. Geological Survey, indicates the site as being underlain by Vashon Till (Qvt). According to this publication, the Vashon Till is described as: "a non -sorted, mixture of clay, silt, sand, pebbles, cobbles, and boulders, all in variable amounts. It typically is hard lodgement till and often is referred to as hardpan. The "hardpan" is largely a result of compaction caused by the great weight of ice hundreds of meters thick. Internal drainage is greatly retarded by the unweathered till". Soil Conditions Soils were visually classified in the general accordance with the Unified Soil Classification System (USCS). After laboratory testing was completed on representative samples, soil descriptions were also developed using the USDA Soil Textural Classification System. Detailed descriptive logs presenting the subsurface conditions encountered, the associated USCS and USDA soil descriptions, and the procedures utilized in the subsurface exploration program are presented in Appendix A. Generalized descriptions of subsurface soil conditions observed in specific areas of the site are presented below. The vertical stratification and horizontal extent of the soil types appeared to vary between explorations. Variations in subsurface conditions exist between the exploration locations and the nature and extent of variations between the explorations may not become evident until Page 2 1� ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 construction. Stratification boundaries on the boring logs represent the approximate depth of changes in soil types, although the transition between materials may have been gradual. If variations become apparent during construction, it may be necessary to reevaluate the recommendations of this report Borings B-1 and B-2 were completed in asphalt -paved areas. The pavement section in boring B-1 was approximately 11/2 inches of asphalt over 1 inch of crushed gravel base course. Boring B-2 encountered approximately 3 inches of asphalt over 31/2 inches of crushed gravel base course. Borings B-3 through B-7 were completed in grass -covered areas and generally encountered 6 to 8 inches of sod, root zone and organic -rich topsoil. Beneath the pavement sections and grass covered areas, soils interpreted as undocumented fill material or possible fill were encountered in borings B-1, B-4, B-5, B-6, and B-7. In general, the fill consisted of loose to dense silty sand with some gravel and sand with some silt and gravel that we interpreted to be of glacial till origin. The fill and possible fill varied in thickness from approximately 41/2 to more than 71/2 feet. Below the fill, grass areas, and pavement sections, native soils consisted of medium dense to very dense silty sand with some gravel and sand with some silt and gravel that we interpreted to be weathered and unweathered glacial till, respectively. Below the crawlspace, both hand -dug test pits disclosed dense glacial till. As part of a previous renovation/addition to the existing building in 1997/1998, we understand that four interior spread footings beneath the northern portion of the building were to have been over - excavated to a depth of 8 feet to remove "loose, organic subgrade material". We have not observed any information that would indicate if this was completed. The fill and possible fill encountered in borings B-5 and B-7 tend to corroborate the anecdotal information from 1997. Groundwater None of the borings encountered groundwater at the time of drilling. Groundwater levels, flow rates and soil moisture conditions should be expected to vary. Groundwater tends to perch within the weathered glacial till during the winter and spring periods of the year and during extended periods of precipitation. Fluctuations of the groundwater levels will likely occur due to seasonal variations in the amount of rainfall, runoff and other factors not evident at the time the explorations were performed. Therefore, groundwater levels during construction or at other times in the life of the structure may be higher than indicated on the logs. The probability of perched water should be considered when developing the design and construction plans for the project. The dense to very dense and silty nature of the native glacial till soils combine to provide low - permeability soils across the site. Therefore, groundwater should be expected to collect within backfilled excavations in the till. Page 3 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Summary of Laboratory Testing Laboratory testing was completed on select soil samples obtained from our borings. Laboratory testing included moisture content and grain size analysis. The results of moisture content testing are presented on the boring logs. Results of grain size testing are provided in Appendix B. Within the upper 10 feet of existing site grades in borings B-1 through B-7, moisture contents ranged from about 7 to 13 percent. Grain -size (sieve) tests indicate fines contents (silt and clay size particles) ranging from about 11 to 35 percent in representative near -surface samples. Only two of the eight samples tested had a fines content of less than 21 percent. CONCLUSIONS AND RECOMMENDATIONS General Considerations in our opinion, development as proposed appears feasible from a geotechnical engineering standpoint utilizing conventional, shallow, spread foundations. The fill and possible fill soils across the site, as well as loose soil reportedly beneath a portion of the existing building, vary in moisture content and relative compaction. This variability will likely become apparent during construction and the amount and extent of over -excavating of unsuitable soils will likely vary across the site. Wet weather prevails in the project vicinity for a significant portion of the year (generally mid -October through April). Site soils contain a significant fraction of fines and these soils will quickly become unstable, soft and unsuitable for reuse as structural fill during periods of seasonal wet weather. The following sections of this report present specific geotechnical recommendations for the project. Our recommendations are based on the observed soil conditions at specific exploration locations. Differing soil conditions than those observed in our borings may become evident during construction. The risk of such differing conditions is elevated on sites such as this site where previously placed fill is apparent. Our recommendations are further based on the assumption that earthwork for site grading, utilities, foundations, floor slabs, and pavements will be monitored by a qualified geotechnical engineer. Seismic Considerations Based on site location and soil conditions, the values provided below are recommended for seismic design. The values provided below are derived from the USGS US Seismic Design Maps Web Application based on USGS hazard data available in 2008. Page 4 ZiDoer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 2012 IBC SEISMIC DESIGN PARAMETERS Description Value C - Site Class C applies to an average soil profile within the top 100 feet consisting predominantly of stiff soils. These 2012 International Building Code Site Classification soils are characterized by average Standard Penetration (I BC) Test blowcounts greater than 50, average shear wave velocities between 1,200 and 2,500 feet per second, and average undrained shear strengths greater than 2,000 __pounds per square foot. Site Latitude 47.18750 N Site Longitude 122.46060 W Spectral Short -Period Acceleration, Ss 1.274g (Site Class B) Spectral I -Second Acceleration, S1 0.498g (Site Class B) Spectral Acceleration for a 0.2-Second Period, SMs 1.274g (Site Class C) Spectral Acceleration for a 1 -Second Period, SM1 0.648g (Site Class C) Design Short -Period Spectral Acceleration, SDs 0.849g (Site Class C) Design 1 -Second Spectral Acceleration, SD1 0.432g (Site Class C) 1 A 100-foot soil profile determination was extrapolated from the borings, correlated with published geologic I literature. The site soils are not considered to be prone to liquefaction due to their relative density. The potential for seismic related settlement is considered low. Based on our analyses, foundation bearing capacity failure is considered unlikely, and settlement of greater than 1 inch is considered to be low during a design -level earthquake provided the soils in the building pad are prepared as recommended in this report. Site Preparation Existinq Structure Removal: We recommend that existing concrete on -grade slabs and foundations be removed prior to grading. The resulting excavations should be backfilled with compacted structural fill or cement -treated soils. It would be possible to reuse the existing concrete for structural fill purposes, stabilization or bridging over areas of soft, unsatisfactory soil, or construction of haul roads and layclown areas, provided it is crushed to a suitable working size. Existing Utility Removal: We recommend that all underground utilities within the proposed building pad be completely removed if they are not going to be reused. Utility pipes outside the building envelope could be abandoned in place, provided they are fully grouted with controlled density fill (CDF) and the trench backfill is density tested to verify that it meets the compaction levels presented in the project specifications. Localized excavations made for removal of utilities or existing unsuitable trench backfill should be backfilled with structural fill as outlined in the following section of this report. Page 5 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Erosion Control Measures: Stripped surfaces and soil stockpiles are typically a source of runoff sediments. We recommend that silt fences, berms, and/or swales be installed around the downslope side of stripped areas and stockpiles in order to capture runoff water and sediment. If earthwork occurs during wet weather, we recommend that all stripped surfaces be covered with straw to reduce runoff erosion, whereas soil stockpiles should be protected with anchored plastic sheeting. Temporary Drainage: Stripping, excavation, grading, and subgrade preparation should be performed in a manner and sequence that will provide drainage at all times and provide proper control of erosion. The near surface site soils have a high fines (silt and clay) content and are therefore highly susceptible to disturbance and erosion when wet. The site should be graded to prevent water from ponding in construction areas and/or flowing into and/or over excavations. Exposed grades should be crowned, sloped, and smooth -drum rolled at the end of each day to facilitate drainage if inclement weather is forecasted. Accumulated water must be removed from subgrades and work areas immediately and prior to performing further work in the area. Equipment access may be limited and the amount of soil rendered unfit for use as structural fill may be greatly increased if drainage efforts are not accomplished in a timely manner. Successful drainage of saturated zones due to accumulations of surface water would be relatively slow due to the fines content of the surficial soils. Instead, aeration, chemical treatment, or removal and replacement would be more expeditious. Runoff from the existing asphalt paved areas should not be allowed to flow into excavation areas. We recommend that asphalt berms or sandbags be used to divert runoff around the excavation areas to a suitable discharge location if the existing pavement is left in place during construction to protect the subgrade. Clearing and Stripping: We anticipate that clearing and stripping will be limited to existing landscape areas. Once surface runoff is controlled, areas of the site to be developed should be stripped of topsoil and vegetation. We estimate that topsoil stripping depths will average about 6 to 8 inches across the site where landscaping is present. Deeper areas of organic -rich soil, such as in the area of tree roots, may be encountered and should be removed to the recommended depth determined in the field by the owner's geotechnical representative. Determination will likely be made based on visual examination. Due to the proposed grading of the site, the existing asphalt pavement will need to be removed. Where possible, we recommend that the existing asphalt be left in place to temporarily protect the subgrade soils. Assessment of Reported Unsuitable Soils: As part of a previous renovation/addition to the existing building in 1997/1998, we understand that four interior spread footings beneath the northern portion of the building were to have been over -excavated to a depth of 8 feet to remove "loose, Page 6 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 organic subgrade material". We have not observed any information that would indicate if this was completed. Once the building is demolished and a backhoe can access the area, we recommend that test pit excavations be completed in this area to determine if additional unsuitable, organic - rich soils are present. If unsuitable soils are present we recommend they be over -excavated and replaced with compacted structural fill. Subgracle Preparation: Once site preparation is complete, all areas of exposed subgrade that do not require over -excavation and are at design subgrade elevation or subgrades that will receive new structural fill should be compacted to a firm and unyielding condition. Areas that may require over -excavation include the foundation and floor slab subgrades in the western portion of the existing building where loose soils were encountered. This will be discussed subsequently. Some moisture conditioning of site soils may be required to achieve a moisture content appropriate for compaction. During periods of extended wet weather, this could entail aeration and drying while during the drier summer months, blending moisture into dry soils may be necessary. A suitable moisture content is generally within ±2 percent of the soil's optimum moisture content. Our laboratory testing indicates that, at the time our explorations were completed, moisture contents of the native glacial till and glacial till fill soils measured in the lab ranged from about 7 to 13 percent. We anticipate the optimum moisture content of the on -site soils would be on the order of 8 to 9 percent. Portions of the proposed building footprint could be underlain by undocumented fill material that was probably placed during the original site development. The relative density of the fill soils, as determined by the Standard Penetration Tests performed during the geotechnical evaluation, indicate the fill varies from loose to medium dense. Because of the variations in relative compaction, we recommend all undocumented fill soils be over -excavated and replaced with structural fill. After over -excavation, the exposed subgrade should be compacted to a minimum of 90 percent of the modified Proctor maximum dry density as determined by ASTIVI D 1557. The replacement backfill should be compacted to a minimum of 95 percent. In floor slab areas, if the fill is deemed to be suitable from a compositional standpoint and it is compacted to a minimum of 90 percent of the modified Proctor maximum dry density throughout, we recommend that the upper foot of the subgrade soil be compacted in place to a minimum of 95 percent of the modified Proctor maximum dry density. Earthwork should be completed during drier periods of the year when the soil moisture content can be controlled by aeration and drying. If earthwork or construction activities take place during extended periods of wet weather, or if the in situ moisture conditions are elevated above the optimum moisture content, the soils could become unstable or not be compactable. In the event the exposed subgrade becomes unstable, yielding, or unable to be compacted due to high moisture conditions, we recommend that the materials be removed to a sufficient depth in order to develop stable subgrade soils that can be compacted to the minimum recommended levels. Page 7 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 The severity of construction problems will be dependent, in part, on the precautions that are taken by the contractor to protect the subgrade soils. Once compacted, pavement and floor slab subgrades should be evaluated through density testing and proof rolling with a loaded dump truck or heavy rubber -tired construction equipment weighing at least 20 tons to assess the subgrade adequacy and to detect soft and/or yielding soils. In the event that the soils are not firm and unyielding, the upper 12 inches of subgrade should be scarified and moisture conditioned as necessary to obtain at least 95 percent of the maximum laboratory density (per ASTIVI D 1557). Those soils which are soft, yielding, or unable to be compacted to the specified criteria should be over -excavated and replaced with suitable material as recommended in the Structural Fill section of this report. Alternatively, over optimum soils could be treated with cement as a method to stabilize and strengthen soft, wet soils. To protect stable subgrades from construction traffic, either inside or outside the building footprint, we recommend using crushed rock or crushed recycled concrete. The thickness of the protective layer should be determined at the time of construction and be based on the moisture condition of the soil and the amount of anticipated traffic. Freezinq Conditions: If earthwork takes place during freezing conditions, all exposed subgrades should be allowed to thaw and then be compacted prior to placing subsequent lifts of structural fill. Alternatively, the frozen material could be stripped from the subgrade to expose unfrozen soil prior to placing subsequent lifts of fill or foundation components. The frozen soil should not be reused as structural fill until allowed to thaw and adjusted to the proper moisture content, which may not be possible during winter months. Structural Fill Materials and Placement Structural fill includes any material placed below foundations, floor slabs and pavement sections, within utility trenches, and behind retaining walls. Prior to the placement of structural fill, all surfaces to receive fill should be prepared as previously recommended in the Site Preparation section of this report. Laboratory Testing: Representative samples of on -site and imported soils to be used as structural fill should be submitted for laboratory testing at least 4 days in advance of its intended use in order to complete the necessary Proctor tests. Reuse of Site Soils as Structural Fill: It is our opinion that the non -organic native and fill soils encountered on the site are suitable for reuse as general structural fill from a compositional standpoint provided they are placed and compacted in accordance with the recommendations presented in this report. Some of the site soils may be wet of optimum at the time of construction and will require moisture conditioning (drying) prior to use as structural fill. The reuse of site soils as structural fill during wet weather will be difficult or impossible due to their moisture sensitivity. Page 8 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Reusing over -optimum soils during periods of wetter, cooler weather would likely require cement stabilization. We recommend that site soils used as structural fill have less than 4 percent organics by weight and have no woody debris greater than 1/2 inch in diameter. We recommend that all pieces of organic material greater than 1/2 inch in diameter be picked out of the fill before it is compacted. Organic -rich soil derived from earthwork activities should be used in landscape areas or be wasted from the site. Imported Structural Fill: Imported structural fill may be required due to weather, wet soil conditions, or other reasons. The appropriate type of imported structural fill will depend on the prevailing weather conditions. During extended periods of dry weather when soil moisture can be controlled, we recommend imported fill meet the requirements of Common Borrow as specified in Section 9-03.14(3) of the 2012 Washington State Department of Transportation, Standard Specifications for Road, Bridge, and Municipal Construction (WSDOT Standard Specifications). The on -site soils would be classified as Common Borrow. During wet weather, higher -quality (lower fines content) structural fill might be required, as Common Borrow may contain sufficient fines to be moisture sensitive. During wet weather we recommend that imported structural fill meet the requirements of Gravel Borrow as specified in Section 9-03.14(l) of the WSDOT Standard Specifications. Retaining Wall Backfill: Retaining walls should include a drainage fill zone extending at least 18 inches back from the back face of wall for the entire wall height. The drainage fill should meet the requirements of Gravel Backfill for Walls as specified in Section 9-03.12(2) of the WSDOT Standard Specifications. Pavement Subgrades: Any structural fill used within the upper one foot below pavement sections should have a minimum California Bearing Ratio (CBR) of 20 at a compaction level of 95 percent of the modified Proctor maximum dry density. A CBR value of 20 is representative of the soils encountered at the site and has been assumed to develop our pavement section recommendations. Moisture Content: The suitability of soil for use as structural fill will depend on the prevailing weather at the time of construction, the in situ moisture content of the soil, and the fines content (that portion passing the US No. 200 sieve) of the soil. As the amount of fines increases, the soil becomes increasingly sensitive to small changes in moisture content. Soils containing more than about 5 percent fines (such as the on -site soils) cannot be consistently compacted to the appropriate levels when the moisture content is more than approximately 2 percent above or below the optimum moisture content (per ASTIVI D 1557). Optimum moisture content is that moisture content which results in the greatest compacted dry density with a specified compactive effort. Page 9 Zlooer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Fill Placement: Structural fill should be placed in horizontal lifts not exceeding 10 inches in loose thickness. Each lift of fill should be compacted using compaction equipment suitable for the soil type and lift thickness. Each lift of fill should be compacted to the minimum levels recommended below based on the maximum laboratory dry density as determined by the ASTM D 1557 Modified Proctor Compaction Test. Moisture content of fill at the time of placement should be within plus or minus 2 percent of optimum moisture content for compaction as determined by the ASTM D1 557 test method. Compaction Criteria: Our recommendations for soil compaction are summarized in the following table. Structural fill for roadways and utility trenches in municipal rights -of -way should be placed and compacted in accordance with the City of Edmonds codes and standards. We recommend that a geotechnical engineer be present during grading so that an adequate number of density tests may be conducted as structural fill placement occurs. In this way, the adequacy of the earthwork may be evaluated as it proceeds. RECOMMENDED SOIL COMPACTION LEVELS Location Minimum Percent Compaction* All fill below building floor slabs and foundations 95 Upper 2 feet of fill below pavements 95 Pavement fill below two feet 92 Retaining wall backfill less than 3 feet from wall 90 Retaining wall backfill more than 3 feet from wall 92 Upper two feet of utility trench backfill 95 Utility trenches below two feet 92 Landscape Areas 90 * ASTM D 1557 Modified Proctor Maximum Dry Density Utility Trenching and Backfilling We recommend that utility trenching conform to all applicable federal, state, and local regulations, such as OSHA and WISHA, for open excavations. Trench excavation safety guidelines are presented in WAC Chapter 296-155 and WISHA RCW` Chapter 49.17. Trench Dewatering: Perched groundwater zones may be encountered in basement, trench and stormwater vault excavations during the winter and spring months but could likely be controlled with sump pits and pumps in the excavations. The depth to and flow rate of perched groundwater will fluctuate throughout the year. At times, seepage could be heavy enough to require flattening the sidewalls of excavations to reduce the risk of caving. Some caving of utility trench sidewalls should be anticipated in association with groundwater seepage. We recommend that any excavations within groundwater seepage zones be undertaken only when suitable clewatering Page 10 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 equipment and temporary excavation shoring are available, or where space is available to flatten the sidewalls. If greater dewatering efforts (such as wells) become necessary, it should be designed and maintained by the contractor. The appropriate type of dewatering system should be determined by the contractor based on the conditions encountered. Utility Subgrade Preparation: We recommend that all utility subgrades be firm and unyielding and free of all soils that are loose, disturbed, or pumping. Such soils should be removed and replaced, if necessary. All structural fill used to replace over -excavated soils should be compacted as recommended in the Structural Fill section of this report. If utility foundation soils are soft, we recommend that they be over -excavated 12 inches and replaced with crushed rock. Structures such as manholes and catch basins which extend into soft soils should be underlain by at least 12 inches of crushed gravel fill compacted to at least 90 percent of the modified Proctor maximum dry density. This granular material could consist of crushed rock, quarry spalls, permeable ballast, or coarse crushed concrete. It may be necessary to place a geotextile fabric over the native subgrade soils if they are too soft to provide a separation between the bedding and subgrade soils. Bedding and Initial Backfill: We recommend that a minimum of 4 inches of bedding material be placed above and below all utilities or in general accordance with the utility manufacturer's recommendations and local ordinances. We recommend that pipe bedding consist of Gravel Backfill for Pipe Zone Bedding as specified in Section 9-03.12(3) of the WSDOT Standard Specifications. All trenches should be wide enough to allow for compaction around the haunches of the pipe, or material such as pea gravel should be used below the spring line of the pipes to eliminate the need for mechanical compaction in this portion of the trenches. If water is encountered in the excavations, it should be removed prior to fill placement. Trench Backfill: Materials, placement and compaction of utility trench backfill should be in accordance with the recommendations presented in the Structural Fill section of this report. In our opinion, the initial lift thickness should not exceed one foot unless recommended by the manufacturer to protect utilities from damage by compacting equipment. Light, hand operated compaction equipment may be utilized directly above utilities if damage resulting from heavier compaction equipment is of concern. Temporary and Permanent Slopes Temporary excavation slope stability is a function of many factors, including: • The presence and abundance of groundwater; • The type and density of the various soil strata; • The depth of cut; • Surcharge loadings adjacent to the excavation; and • The length of time the excavation remains open. Page 11 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 As the cut is deepened, or as the length of time an excavation is open, the likelihood of bank failure increases; therefore, maintenance of safe slopes and worker safety should remain the responsibility of the contractor, who is present at the site, able to observe changes in the soil conditions, and monitor the performance of the excavation. It is exceedingly difficult under the variable circumstances to pre -establish a safe and ,.maintenance -free" temporary cut. slope angle. Therefore, it should be the responsibility of the contractor to maintain safe temporary slope configurations since the contractor is continuously at the job site, able to observe the nature and condition of the cut slopes, and able to monitor the subsurface materials and groundwater conditions encountered. We recommend the contractor make a determination of excavation side slopes based on classification of soils encountered at the time of excavation in accordance with the guidelines presented in Section 296-155, Part N of the Washington State Administrative Code and applicable construction industry specific guidelines. Based on the conditions encountered in the borings, it appears the soils would be classified as Type C. Temporary cuts may need to be constructed at flatter angles based upon the soil moisture and groundwater conditions at the time of construction. Adjustments to the slope angles should be determined by the contractor at that time. Unsupported vertical slopes or cuts deeper than 4 feet are not recommended if worker access is necessary. The cuts should be adequately sloped, shored, or supported to prevent injury to personnel from local sloughing and spalling. We recommend that all permanent cut or fill slopes constructed in native soils be designed at a 2Y2H:lV (Horizontal:Vertical) inclination or flatter. All permanent cut and fill slopes should be adequately protected from erosion both temporarily and permanently. Stormwater Detention Vault A relatively large detention vault is planned beneath the main parking lot. For planning purposes, we recommend using 1H:1V temporary side slope inclinations to determine the temporary excavation limits and evaluate that such an excavation would not interfere with existing utilities or other features that cannot be disturbed. If interference with existing utilities and structures must be avoided, other options are available that could allow for steeper (up to vertical) slopes. No soil borings were completed in the area of the proposed vault. However, based on the soil conditions encountered in the borings advanced in other areas, it appears the vault would be supported on dense to very dense native soils. If shallow footings are used, we recommend using a maximum allowable bearing capacity of 3,500 psf. We recommend the base slab be supported on a minimum of 6 inches of crushed gravel conforming to WSDOT Standard Specification 9- 03.9(3) for Crushed Gravel Base Course or Crushed Gravel Top Course. We recommend that drainage be provided around the vault since the surrounding soils are relatively impermeable and groundwater seepage will collect in the backfilled excavation. We Page 12 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 recommend that a footing drain be installed as deep as possible, preferably at the base of the structure, to prevent the build-up of hydrostatic pressure. If the drain pipe cannot be installed at the base of the structure due to elevations of nearby tie-in drainage structures, we recommend the vault be designed for hydrostatic pressure below the elevation of the drain pipe. We recommend the walls be backfilled with a minimum of 18 inches of free -draining material that communicates with the drain pipe. The drainage aggregate should consist of material meeting the requirements of WSDOT 9-03.12(2) Gravel Backfill for Walls. Drain pipe perforations should be protected using a non -woven filter fabric such as Mirafi 140N. For on -site soils placed on top of a vault as structural fill, as well as the asphalt base course and asphalt surfacing, we recommend using a moist unit weight of 140 pounds per cubic foot. Preliminary Stormwater Infiltration Suitability We understand the stormwater management system may include infiltration and/or detention structures. Preliminary estimated infiltration rates for potential stormwater management areas were determined in general accordance with Appendix C of the Edmonds Stormwater Code Supplement. ASTM gradation testing was completed on eight samples of the receptor soils obtained from our borings. We used the test results to determine the textural classification in accordance with the methodology presented in the USDA Soil Survey Manual (1993). Our testing indicates the receptor soils may be somewhat variable across the site. The following table presents our findings and the associated long-term estimated infiltration rates.

Loamy Sand 0.5 The long-term infiltration rates presented in the City's Stormwater Code Supplement are based on the Washington State Department of Ecology (WSDOE) Stormwater Management Manual for Western Washington (2005). The published infiltration rates are based on the assumption that the receptor soils are homogeneous and normally consolidated. The on -site soils originated as glacial till which have been consolidated by thousands of feet of ice and are over -consolidated as a result. The soil density is not represented in the gradation tests and in our opinion greatly Page 13 ZiDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 reduces the in situ infiltration rate. The actual infiltration rates should be considered negligible without verifying the actual infiltration rates through field testing. Based on the conditions disclosed by the explorations, laboratory testing results, and experience with other projects of a similar nature, it is our opinion that conventional storm water infiltration is not feasible at the site. In the event that rain gardens are constructed for treatment purposes, we recommend that overflows be installed that will allow excess water to be piped to the stormwater system. �fiallpw Building Founditi-ons In our opinion, shallow spread and continuous footings are suitable for support of the proposed structure, from a geotechnical engineering standpoint. However the wall backfill for the basement should not be relied upon for support of main floor foundations that tie into the basement walls because the wall backfill should be free -draining and could shift or settle slightly after placement.. We recommend that foundations in the wall backfill zone step down as they approach the wall backfill so they remain supported by native soils. Alternatively, the shallow foundation should be designed as a grade beam to span over the width of the wall backfill. Bearing Subgrade: The loose soils encountered in borings B-1 and B-5 could extend under some of the proposed footings in those respective areas. There also could be other areas of loose bearing soils that may not become evident until construction either because they are presently under the existing building or they were not encountered in our borings. ZGA has located the test pit logs for the addition and it appears that medium dense fill and native soils extended to depths of 3 to 7 feet below former site grades. The undocumented fill soils reported should not be considered suitable for support of the new foundations. We recommend that the foundations be supported on properly prepared structural fill placed above undisturbed native soils or directly on the undisturbed native soils. Soils that are loose to medium dense should be over -excavated to expose dense native soils. Where foundation subgrade soils are over -excavated and backfilled with structural fill, the excavation should extend laterally away from each side of the footing a distance of 8 inches for each foot the excavation extends vertically below the foundation. If lean mix is used to backfill excavations below footings, the excavation only needs to extend 6 inches beyond the limits of the foundation regardless of the depth of over -excavation. The resulting excavation should be backfilled with lean mix having a minimum 28-day compressive strength of 100 psi. The foundation subgraide should be observed and tested by a representative of ZGA prior to placement of any structural fill, formwork or reinforcing steel. I Page 14 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Allowable Bearing Pressure: Based on our understanding of grading for the building, we anticipate the foundation bearing soils could vary from medium dense to very dense. In order to limit differential settlements to tolerable limits, we recommend using an allowable bearing capacity that is appropriate for the medium dense soils. Continuous and column footings bearing on undisturbed medium dense to very dense native soil and structural fill compacted to a minimum of 95 percent of the modified Proctor maximum dry density should be designed for a maximum allowable, net, bearing capacity of 2,500 psf. A one-third increase of the bearing pressure may be used for short -tern dynamic loads such as wind and seismic forces. Shallow Foundation Depth and Width: For frost protection, the bottom of all exterior footings should bear at least 18 inches below the lowest adjacent outside grade, whereas the bottoms of interior footings should bear at least 12 inches below the surrounding slab surface level. We recommend that all continuous wall and isolated column footings be at least 12 and 24 inches wide, respectively. Lateral Resistance: We recommend using allowable base friction and passive earth values of 0.33 and 250 pcf equivalent fluid pressure, respectively. We recommend that passive resistance be neglected in the upper 18 inches of embedment. Estimated Settlement: Assuming the foundation subgrade soils are prepared in accordance with recommendations presented herein, we estimate that total and differential settlements will be less than 1 inch and % inch, respectively. Backfilled Permanent Retaining Walls Lateral Earth Pressures: The lateral soil pressures acting on backfilled retaining walls will depend on the nature and density of the soil behind the wall, and the ability of the wall to yield in response to the earth loads. Yielding walls (i.e. walls that are free to translate or rotate) that are able to displace laterally at least 0.001H, where H is the height of the wall, may be designed for active earth pressures. Non -yielding walls (i.e. walls that are not free to translate or rotate) should be designed for at -rest earth pressures. Non -yielding walls include walls that are braced to another wall or structure, and wall corners. Assuming that walls are backfilled and drained as described in the following paragraphs, we recommend that yielding walls supporting horizontal backfill be designed using an equivalent fluid density of 35 pcf (active earth pressure). Non -yielding walls should be designed using an equivalent fluid density of 50 pcf (at -rest earth pressure). Surcharge pressures due to sloping backfill, adjacent footings, vehicles, construction equipment, etc. must be added to these lateral earth pressure values. For traffic loads, we recommend using an equivalent two foot soil surcharge of about 250 psf. For loading docks, point, continuous or evenly distributed loads above the dock will result in horizontal pressure on the wall. The Page 15 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 appropriate loading conditions should be incorporated into the loading dock wall design, or we can provide surcharge criteria for loading conditions behind the loading dock wall, if requested. For yielding walls with level backfill conditions, we recommend that a uniformly distributed seismic pressure of 4.5H psf for the active case and 9.OH psf for the at -rest case, where H is the height of the wall, be applied to the walls. The above equivalent fluid pressures are based on the assumption of no buildup of hydrostatic pressure behind the wall. If groundwater is allowed to saturate the backfill soils, hydrostatic pressures will act against a retaining wall; however, if the recommended drainage system is included with each retaining wall, we do not expect that hydrostatic pressures will develop. Drainage: Adequate drainage measures must be installed to collect and direct subsurface water away from subgrade walls. All backfilled walls should include a drainage aggregate zone extending a minimum of 18 inches from the back of wall for the full height of the wall. The drainage aggregate should consist of material meeting the requirements of WSDOT Standard Specification 9-03.12(2), Gravel Backfill for Walls. A minimum 4-inch diameter, perforated PVC drain pipe should be provided at the base of the backfilled wall footings to collect and direct subsurface water to an appropriate discharge point. Drain pipe perforations should be protected using a non -woven filter fabric such as Mirafi 140N. Footing drains should be installed below the cold joints between backfilled walls and the underlying foundations. If this is not possible, we recommend designing a waterstop into the cold joint to prevent the migration of water beneath the interior floor slab. An extra level of water -proofing could be applied directly to the backfilled wall in the form of a drainage composite. Generally, drainage composites are installed from the top of the backfill to the top of the footing. Free -draining aggregate is placed over the top of the footing and down the side of the footing so that the collected water can flow to the footing drain. Products such as Miradrain by Tencate and J-Drain 400 by JDR Enterprises would be suitable for this application. We can provide names of other products upon request. Wall drainage systems should be independent of other drainage systems such as roof drains. On -Grade Concrete Slabs Subgracle Preparation: All fill placed beneath floor slabs should be compacted to a minimum of 95 percent of the modified Proctor maximum dry density. It is possible that some of the existing fill within the footprint of the proposed building will not meet this recommended level of compaction. As such, the actual amount of over -excavation and replacement will be dependent on the horizontal and vertical extent of existing fill and its relative compaction. Existing fill material that is not compacted to a minimum of 90 percent of the modified Proctor maximum dry density should be reworked and compacted in order to achieve the minimum recommended compaction levels. Page 16 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April22,2014 Slab Base: To provide a uniform slab bearing surface, we recommend the on -grade slabs be underlain by a 4-inch thick layer of compacted crushed gravel meeting the requirements of Crushed Surfacing Top Course as specified in Section 9-03.9(3) of the WSDOT Standard Specifications. We further recommend that the fines content (that portion passing the US No. 200 sieve) of the crushed gravel be limited to a maximum of 7.5 percent. Vapor Barrier: A vapor barrier is not necessary beneath slab on grade floors unless moisture sensitive floor coverings and/or adhesives are used. If a vapor barrier is used, we recommend using a 10-mil puncture -resistant product that is classified as a Class A vapor retarder in accordance with ASTM E1745. Puncturing the vapor barrier should be avoided; construction traffic should not be allowed to drive over any vapor barrier material. We recommend the barrier have taped overlapping joints and where pipes and other objects penetrate the barrier, we also recommend taping these. When conditions warrant the use of a vapor retarder, the slab designer and slab contractor should refer to ACI 302 and ACI 360 for procedures and cautions regarding the use and placement of a vapor retarder/barrier. Subgrade Modulus: For design of on -grade concrete slabs supported on compacted fill soils, we recommend a vertical modulus of subgrade reaction of 225 pounds per cubic inch (pci) be used. This value is suitable if the on -site soils are reused as structural fill. beneath the slab. Drainage Considerations Surface Drainage: Final site grades should be sloped to carry surface water away from buildings and other drainage -sensitive areas. Additionally, site grades should be designed such that concentrated runoff on softscape surfaces is avoided. Subsurface Perimeter Drainage: We recommend a permanent footing drain system be installed around the building perimeter. Drains for footings and backfilled walls should consist of an aggregate drainage zone (as recommended in the Structural Fill section) and a drain pipe. Drain pipes should consist of a minimum 4-inch diameter, rigid -wall, perforated drainpipe installed at the base of the wall footing. The pipe should be wrapped in a filter sock (such as Mirafi 140N) to prevent sand and gravel from washing into the perforations. To prevent water backup in the pipes, the drainpipes should be connected at regular intervals to a tightline system leading to a suitable discharge. Cleanouts should be provided for future maintenance. The footing drain system must be separate from the roof drain system. Page 17 ZIDDer Geo, Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Rockeries Based on our review of the current site plan, rockeries are planned around the east, west and south sides of the main parking lot. The proposed rockeries will be situated along the property boundary and will support fill soils. The rockeries will vary in exposed height from about 1 1/2to 31/2 feet will support structural fill parked automobile surcharges. In general, the purpose of rockeries is to provide erosion protection for stable cuts made in competent native soils. Rockeries can be used to support limited heights of fills. However, the fill must be over -built and then cut back in order to provide a competent, compacted core which the rockery will support. In this case, over -building the fill would result in the fill encroaching on the adjacent property. If a temporary construction easement can be obtained, over -building the fill would be feasible. Otherwise, we recommend the fill be reinforced with a woven geotextile such as Mirafi HP 370 or equivalent. A typical detail of a reinforced fill rockery is provided on the attached Figure 2, Reinforced Fill Rockery. Pavements Asphalt Pavements Pavement Life and Maintenance: It should be realized that asphaltic pavements are not maintenance -free. The following pavement sections represent our minimum recommendations for an average level of performance during a 20-year design life; therefore, an average level of maintenance will likely be required. Thicker asphalt, base, and subbase courses would offer better long-term performance, but would cost more initially. Conversely, thinner courses would be more susceptible to "alligator" cracking and other failure modes. As such, pavement design can be considered a compromise between a high initial cost and low maintenance costs versus a low initial cost and higher maintenance costs. Soil Design Values: The native subgrade soils are anticipated to consist of a varying mixture of silt, sand and gravel. Based on the typical values provided by compacted glacial till fill, we have estimated a California Bearing Ratio (CBR) value of 20 percent for this project. Traffic Desi-qn Values: No traffic loading was provided for this project. We have assumed low traffic volumes of less than 50,000 ESALs over a 20-year design life for light- and heavy-duty pavements. If traffic routes are expected across the site that could increase the estimated traffic count, ZGA should be notified so that we can re -analyze the pavement sections. Recommended Pavement Sections: For light duty pavements (parking lot areas), we recommend 21/2 inches of asphalt concrete over 4 inches of crushed rock base course. For heavy duty pavements (main access roads, truck delivery routes, etc.), we recommend 3 inches of asphalt concrete over 4 inches of crushed rock base course. Page 18 ZIDDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Materials and Construction: We recommend the following regarding asphalt pavement materials and pavement construction. Sub -grade Preparation: The upper 12 inches of pavement subgrade should be prepared in accordance with the recommendations presented in the Subgrade Preparation section of this report. Asphalt Concrete: We recommend that the asphalt concrete conform to Section 9-02.1(4) for PG 58-22 or PG 64-22 Performance Graded Asphalt Binder as presented in the 2012 WSDOT Standard Specifications. We also recommend that the gradation of the asphalt aggregate conform to the aggregate gradation control points for 1/2-inch mixes as presented in Section 9-03.8(6), HMA Proportions of Materials. We recommend that the mix design of the proposed asphalt be based on gyratory compaction levels using 50 or 75 gyrations (not 100 or more). Base Course: We recommend that the crushed aggregate base course conform to Section 9-03.9(3), Crushed Surfacing Base Course, of the WSDOT Standard Specifications. Compaction: All base material should be compacted to at least 95 percent of the maximum dry density determined in accordance with ASTM D 1557. We recommend that asphalt be compacted to a minimum of 92 percent and a maximum of 96 percent of the Rice (theoretical maximum) density. Concrete Pavements Concrete Properties and Thickness: Concrete pavement design recommendations are based on an assumed modulus of rupture of 600 psi and a minimum compressive strength of 4,000 psi for the concrete. For light -duty pavements, we recommend 5 inches of concrete over 3 inches of crushed aggregate base. For heavy duty pavements, we recommend 51/2inches of concrete over 3 inches of crushed aggregate base. CLOSURE The analysis and recommendations presented in this report are based, in part, on the explorations completed for this study. The number, location, and depth of the explorations were completed within the constraints of budget and site access so as to yield the information to formulate our recommendations. Project plans were in the preliminary stage at the time this report was prepared. We therefore recommend we be provided an opportunity to review the final plans and specifications when they become available in order to assess that the recommendations and design considerations presented in this report have been properly interpreted and implemented into the project design. Page 19 MoDer Geo Associates. LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 The performance of earthwork, structural fill, foundations, and pavements depend greatly on proper site preparation and construction procedures. We recommend that Zipper Geo Associates, LLC be retained to provide geotechnical engineering services during the earthwork - related construction phases of the project. If variations in subsurface conditions are observed at that time, a qualified geotechnical engineer could provide additional geotechnical recommendations to the contractor and design team in a timely manner as the project construction progresses. 11 Page 20 _iA REMOVE EXIST.

STRUCTURAL FILL PLACED AND COMPACTED IN ACCORDANCE NTH GEOTECHNICAL REPORT FIELD EXPLORATION PROCEDURES AND LOGS FIELD EXPLORATION PROCEDURES Our field exploration program for this project included completion of seven exploratory borings (designated B-1 through B-7) across the site and two shallow hand -excavated test pits (TP-1 and TP-2) beneath the existing building. The borings extended to depths of approximately 8% to 14 feet below ground surface (bgs) while the test pits were completed to a depth of 11/2 feet. The approximate locations of the borings are presented on Figure 1, the Site and Exploration Plan. Exploration locations were determined in the field by measuring distances from existing site features shown on a survey provided by the project civil engineer. As such, the exploration locations should be considered accurate to the degree implied by the measurement method. The following sections describe our procedures associated with the explorations. Descriptive logs of the explorations are enclosed in this appendix. Soil Borings Borings were advanced with a hollow -stem auger, using a small track mounted drill rig and a portable Acker rig operated by an independent drilling company (Geologic Drill) working under subcontract to our firm. A geotechnical engineer from ZGA continuously observed the borings, logged the subsurface conditions encountered, and obtained representative soil samples. All samples were stored in moisture -tight containers and transported to our laboratory for further visual classification and testing. As part of the testing program, all of the samples were visually examined in the laboratory and classified in accordance with the attached General Notes. Throughout the drilling operation, soil samples were obtained at 2.5- to 5-foot intervals by means of the Standard Penetration Test (ASTM: D 1586). This testing and sampling procedure consists of driving a standard 2-inch outside diameter steel split spoon sampler 18 inches into the soil with a 140-pound hammer free failing 30 inches. The number of blows required to drive the sampler through each 6-inch interval is recorded, and the total number of blows struck during the final 12 inches is recorded as the Standard Penetration Resistance, or "blow count" (N value). If a total of 50 blows are struck within any 6-inch interval, the driving is stopped and the blow count is recorded as 50 blows for the actual penetration distance. The resulting Standard Penetration Resistance values indicate the relative density of granular soils and the relative consistency of cohesive soils. The enclosed boring logs describe the vertical sequence of soils and materials encountered in each boring, based primarily upon our field classifications and supported by our subsequent laboratory examination and testing. Where a soil contact was observed to be gradational, our logs indicate the average contact depth. Where a soil type changed between sample intervals, we inferred the contact depth. Our logs also graphically indicate the blow count, sample type, sample number, and approximate depth of each soil sample obtained from the boring, as well as any laboratory tests performed on these soil samples. If any groundwater was encountered in a borehole, the approximate groundwater depth, and date of observation, is depicted on the log. Groundwater depth estimates are typically based on the moisture content of soil samples, the wetted portion of the drilling rods, the water level measured in the borehole after the auger has been extracted, or through the use of an observation well. The boring logs presented in this appendix are based upon the drilling action, observation of the samples secured, laboratory test results, and field logs. The various types of soils are indicated as well as the depth where the soils or characteristics of the soils changed. It should be noted that these changes may have been gradual, and if the changes occurred between sample intervals, they were inferred. Test Pits The test pits were excavated in the crawlspace of the existing building using hand tools.

Located approximately 75 feet east and 5 feet south of NW building corner APPENDIX B LABORATORY TESTING PROCEDURES AND RESULTS LABORATORY TESTING PROCEDURES A series of laboratory tests were performed during the course of this study to evaluate the index and geotechnical engineering properties of the subsurface soils. Descriptions of the types of tests performed are given below. Visual Classification Samples recovered from the exploration locations were visually classified in the field during the exploration program. Representative portions of the samples were carefully packaged in moisture tight containers and transported to our laboratory where the field classifications were verified or modified as required. Visual classification was generally done in accordance with ASTM D 2488. Visual soil classification includes evaluation of color, relative moisture content, soil type based upon grain size, and accessory soil types included in the sample. Soil classifications are presented on the exploration logs in Appendix A. Moisture Content Determinations Moisture content determinations were performed on representative samples obtained from the explorations in order to aid in identification and correlation of soil types. The determinations were made in general accordance with the test procedures described in ASTM D 2216. Moisture contents are presented on the exploration logs in Appendix A. Grain Size Analysis A grain size analysis indicates the range in diameter of soil particles included in a particular sample. Grain size analyses were performed on representative samples in general accordance with ASTM D 2487. The results of the grain size determinations for the samples were used in classification of the soils, and are presented in this appendix.

This tree has lost a large area of significant tree roots from its Critical Root Zone potentially creating a high risk of tree failure. Even if this tree is retained and tree failure does not occur, the impact of constr . uction into the Critical Root Zone would likely result in this tree's death. Introduction As requested by Mr.. David Wilson of Ca rletti Architects P.S,�on February 12, 2015, 1 assessed one Douglas fir, Pseudisitsuga menziesii tree for health and condition at the Prestige Care Project, 21008 76th Avenue West, Edmonds,.WA 98028. Specifically, I was asked to assess the impact of construction work on this tree See photo 1'.) and provide recommendations. for tree management. The assessed Douglas fir is located near the north property line of this project., There has been a reduction in grade four feet south of the tree to allow for. construction. 15119 McLean Aoad - Moulit-Vernon, WA 96��3' Office (MO)428�5810 Fax (360) 428-4822 Cell (366) 770-9921 Email: jimb-ufsinc@V�avecable.com Pla.rining, Managi,ng, & Restori'nq Urba,n Greensp,aces wA-.�l.urbanfqrestryservices,com Method of Assessment The methodology to evaluate these trees follows the criteria provided in the Tree Risk Assessment Qualification (TRAQ) training. TRAQ was developed, and is administered, by the International Society of Arboriculture (ISA) and follows the ISA's Best Management Practices - Tree Risk Assessment publication, and American National Standards Institute (ANSI) A300 (Part 9), Tree, Shrub, and Other Woody Plant Management - Standard Practices (Tree Risk Assessment a. Tree Structure Assessment.) A Level 2 Basic Assessment is a detailed visual inspection of a tree and its surrounding. site, and a synthesis of the information collected. It requires that a tree risk assessor walk completely around the tree, looking at the site, buttress roots, trunk, and branches. This basic assessment may include the use of simple tools to gain additional information about the tree or defects. Defects found in a level 2 Basic Tree Assessment may require a Level 3 assessment for further testing and analysis. Tree condition is determined based on visual inspection of the ' above -ground portions of the trees. Of particular concern is trunk soundness, tree structure, bud fullness and color, twig length, crown ratio, density of leaves, evidence of disease -causing bacteria, fungi or virus, deadwood, and dead or broken hanging limbs. While no one can predict with absolute certainty which trees will fail and which trees will remain healthy, by methodical process we can predict those most likely to fail by the conditions observed and take appropriate action to reduce or eliminate the potential hazard. Findings This Douglas fir has a diameter of 23.4 inches at 4.5 feet height (d.b.h.). The tree has codominant trunks with poor and weak structure, including included bark and twisted trunks. Vigor is currently good. The Critical Root Zone required to maintain the health and condition of this tree is 24 feet radius. See the enclosed Critical Root Zone Explanation. Construction work has cut the grade at four feet south of the tree. This� cut in grade has Carletti Architects / Prestige Care Project - Level 2, Basic Tree Assessment Urban Forestry Services, Inc. February 27, 2015 Page 2 of I severed two significant roots of 8-inches and 10-inches diameter. Photo 2 shows the 10-inch root. The impact of the cut in grade has affected over 40% of the Critical Root Zone. In the past, construction north of the tree appears to have impacted a similar area of the Critical Root Zone. The past. development to the north is also likely to have resulted in significant root loss from this tree. Recommendation: Remove Douglas fir The impact of root severance and grading will result in a significant reduction in tree stability. The risk of tree failure is high because of root severance. This tree targets the residences on the north property and the Prestige Care Project development south of the tree. If this tree is retained, and failure does not occur, it will likely die as a result of impact from root loss in the Critical Root Zone south of the tree.

Mr. David Wilson 116 E. Fir St, Suite A Mount Vernon, WA 98273 Approximate Location of Assessed Tree Date: February, 2015 Not To Scale Location of Tree is Approximate Only to Critical Root Zone (CRZ) = 12" Radius for every Tree inch diameter is generally considered optimum protection. Perimeter Critical Root Zone (PCRZ) = the outer half of the CRZ The greater the disturbance allowed in this area, the greater Post Ca re is required. *14, 4 L i . Tree Trunk 'e-00 Interior Critical Root Zone (ICRZ) = the inner half of the CRZ Protecting only this area would cause significant impact to the tree, potentially life threatening, and would require maximum Post Care Treatment to retain the tree. See Post Care Treatment below. The Critical Root Zone (CRZ) of a tree is -established on the basis of the trunk diameter. The CRZ is a circular area which has a radius of 12 inches to every inch diameter of trunk measured at 4.5 feet above grade. Root systems will vary both in depth and spread.depending on size of tree, soils, water table, species and other factors. However, this CRZ description is generally accepted in the tree industry. Protecting this entire area should result in no adverse impact to the tree. The above CRZ drawing has been further differentiated into the 'Perimeter' (PCRZ) and 'Interior' (ICRZ) to help define potential impact and required Post Care. Generally, the full PCRZ is considered the optimum amount of root protection for a tree. As one encroaches into the "Perimeter CRZ, but not into the "Interior CRZ" the greater Post Care the tree would require to remain alive and stable. The 'Interior CRZ is half the radius of the full PCRZ. Disturbance into the ICRZ could destabilize or cause the tree to decline. The absolute maximum disturbance allowed should leave the 'Interior' CRZ undisturbed if the.tree.is to have any chance of survival. This 'Interior' CRZ would approximately equal the size of a rootball needed to transplant this tree which in turn would require extensive Post Care and possibly guying. Post Care Treatment includes but may not be limited to; regular irrigation, misting, root treatment with special root hormones, mulching, guying and monitoring for several years.

The opinions in this Assessment are given based on observations made and using generally accepted professional judgment, however, because trees and plants are living organisms and subject to change, damage, and disease, the results, observations, recommendations, and analysis took place and no guarantee, warranty, representation, or opinion is offered or made by Urban Forestry Services, Inc. as to the length of the validity of the results, observations, recommendations, and analysis contained within this Assessment. As a result, the Client shall not rely upon this Assessment, save and except for representing the circumstances and observations, analysis, and recommendations that were made as at the date of such inspections. It is recommended that the trees discussed in this Assessment should be re -assessed periodically. Urban Forestry Services, Inc. shall not be required to give testimony or to attend court by reason of this report unless subsequent contractual arrangements are made, including payment of an additional fee for such services as described in our fee schedule and contract of engagement. Sketches, diagrams, graphs, and photographs in this report, being intended as visual aids, are not necessarily to scale and should not be construed as engineering or architectural reports or surveys. 2. Reaction of Assessment The Assessment carried out was restricted to the Property. No assessment of any other trees or plants has been undertaken by Urban Forestry Services, Inc. Urban Forestry Services, Inc. is not legally liable for any other trees or plants on the Property except those expressly discussed herein. The conclusions of this Assessment do not apply to any areas, trees, plants, or any other property not covered or referenced in this Assessment. 3. Professional Responsibility In carrying out this Assessment, Urban Forestry Services, Inc. and any Assessor appointed for and on behalf of Urban Forestry Services, Inc. to perform and carry out the Assessment has exercised a reasonable standard of care, skill, and diligence as would be customarily and normally provided in carrying out this Assessment. The Assessment has been made using accepted arboricultural techniques. These include a visual examination of each tree for structural defects, scars, external indications of decay such as fungal fruiting bodies, evidence of insect attack, discolored foliage, the condition of any visible root structures, the degree and direction of lean (if any), the general condition of the tree(s) and the surrounding site, and the current or planned proximity of property and people. Except where specifically noted in the Assessment, none of the trees examined on the property were dissected, cored, probed, or climbed and detailed root crown examinations involving excavation were not undertaken. I While reasonable efforts have been made to ensure that the trees recommended for retention are healthy, no guarantees are offered, or implied, that these trees, or all parts of them will remain standing. It is professionally impossible to predict with absolute certainty the behavior of any single tree or group of trees, or all their component parts, in all given circumstances. Inevitably, a standing tree will always pose some risk. Most trees have the potential to fall, lean, or otherwise pose a danger to property and persons in the event of adverse weather conditions, and this risk can only be eliminated if the tree is removed.

Mr. Terry Lewis, an AHERA-certified Building Inspector from Bureau Veritas conducted the survey on August 13, 2008. The purpose of the survey was to fulfill the owner's requirement to perform an inspection for asbestos -containing materials (ACM) in a building prior to demolition or renovation. The following ACM were reported by the analytical laboratory to contain >1% asbestos: • Off white, Streaked Floor Tile, 9"x 9", with mastic Room 105 sprinkler room Quantity - 80 square feet • Gray Cement Asbestos Board nailed to walls: Room 105 sprinkler room Quantity - 110 square feet • Pipe insulation covering runs and fittings: Crawlspaces Quantity — 1400 linear feet • Pipe insulation debris: Crawlspace dirt floors Quantity — throughout The following materials were found to have trace amounts of asbestos (less than one percent, thus they are not considered asbestos -containing): * Wallboard walls and ceilings Materials containing one percent or less are regulated by the Washington State Department of Labor and Industries for worker protection purposes only and are not regulated to the same degree as materials containing greater than one percent asbestos (asbestos -containing materials). 1.0 INTRODUCTION Prestige Care, Inc. (Prestige) retained Bureau Veritas North America, Inc. (Bureau Veritas) to conduct an asbestos survey of the multi -winged, single story skilled nursing facility, Prestige Care and Rehabilitation of Edmonds, located at 21008 76th Avenue W. in Edmonds, Washington. Mr. Terry Lewis, an Environmental Protection Agency (EPA) Asbestos Hazard Emergency Response Act (AHERA)-certified Building Inspector, conducted the inspection on August 13, U V 2008. The scope of services provided during the survey is described in Bureau Veritas Proposal Number 4109.08.114, dated August 5, 2008. 2.0 DESCRIPTION OF ASSESSMENT 2.1 PURPOSE The purpose of the survey was to fulfill the owner's requirement to perform an inspection for asbestos -containing materials (ACM) in a building prior to renovation and to assist in providing Prestige with information regarding the extent of asbestos -containing materials in the building. 2.2 SCOPE The scope of the ACM inspection included the building's accessible spaces or areas. Modified EPA AHERA guidelines were followed in conducting the asbestos survey. This was based on our proposal number 4109.08.114, dated August 5, 2008, which was authorized by Prestige Care and Rehabilitation on August 6, 2008. 2.3 SOURCES OF INFORMATION During the course of the assessment the following person provided information or assistance to the Bureau Veritas investigator: Name Affiliation Miguel E. Leon Maintenance Director, Prestige Care and Rehabilitation of Edmonds The information supplied to Bureau Veritas during the course of this project was assumed to be complete, true, and correct and were relied upon by the Bureau Veritas investigator. Additional sampling and survey work was performed by Bureau Veritas to verify extent of ACM. 2.4 BUILDING DESCRIPTION The site is comprised of a one story building and attached carport, asphalt parking lot, and small landscaped areas. The building was constructed in 1964, according to the information on file in the Snohomish County records. The total interior floor space of the building is approximately 29, 100 square feet. The building is constructed of a metal and wood frame on a concrete slab foundation. The exterior walls are finished with rock and rock chips on concrete. The roof consists of built up asphaltic roofing materials. The interior of the building consists of multiple patient rooms, staff offices, storage areas, dining rooms, restrooms, physical therapy area, exam rooms, kitchen, laundry room, maintenance office and shop, shower areas, and common areas. The interior wall finishes consist of drywall, with nailed -on wood mid rails. The interior ceiling consists of gypsum wall board (GWB). Interior floor finishes consist of glued -down carpeting, vinyl floor tiles, vinyl floor sheeting, and unfinished concrete. The heating was by natural gas forced air units. General piping insulation includes foam, fiberglass insulation, air cell insulation or the piping was not insulated. Accessible electrical wire insulation appeared to be plastic. 2 V E P17 W,,WRI A U_ RI T A S 2.5 BUILDING INSPECTION, SAMPLING, AND ANALYSIS 2.5.1 Building Inspection On August 13, 2008, Bureau Veritas' representative, Mr. Terry Lewis, an AHERA-accredited asbestos Building Inspector (Accreditation No. 1028916, expiration date: 4/16/09), conducted a walkthrough assessment of the building. A copy of Mr. Lewis's accreditation certificate is included in Appendix B. The walkthrough assessment provided a visual inspection of the readily accessible portions of the building. Bureau Veritas recorded the areas of the building inspected, as well as areas where materials suspected of containing asbestos were located. 2.5.2 Sampling Bureau Veritas inspected the interior of the building for suspect ACM including thermal system insulation (TSI), surfacing materials, and miscellaneous materials (e.g., floor tiles, ceiling tiles). When materials suspected of containing asbestos were identified, Bureau Veritas collected representative bulk samples from each homogeneous area (HA). No roof samples or exterior samples were taken during this survey. If the analytical results indicate that all the samples collected per HA do not contain asbestos, then the HA (material) is considered a non -ACM. However, if the analytical results of one or more of the samples collected per HA indicate that asbestos is present in quantities of greater than one percent asbestos by weight as defined by the United States Environmental Protection Agency (USEPA), all of the HA (material) is considered to be an ACM regardless of any other analytical results. Material, which can visually be determined to be non -asbestos (i.e., fibrous glass, foam rubber, etc.) by the accredited inspector are not required to be sampled. Miscellaneous materials require adequately representative sampling, which is typically done by collecting at least three samples per material. Inspectors rely on other survey observations such as the condition, friability, and quantity of material to determine what would be a sufficient amount of samples to accurately evaluate the presence or absence of asbestos in a building material. From the list of suspect homogeneous materials, a physical assessment was performed for each material on the list. A physical assessment includes evaluating the condition, assessing the potential for disturbance, and determining the friability of each material. Friability is a term used to describe the ease in which a building material inherently lends itself to disturbance. For purposes of this report the definition of, "friable" materials are those that can be crumbled or reduced to powder by hand pressure when dry. Each material on the list was further classified into one of three categories, which have specific sampling requirements for each category. Thermal System Insulation: Refers to insulation used to inhibit heat gain or loss on pipes, boilers, tanks, ducts, and various other building components. Surfacing Materials: Refers to spray -applied or trowel -applied surfaces such as plaster ceilings and walls, fireproofing, textured paints, textured plasters, and spray -applied acoustical surfaces. Miscellaneous Materials: Refers to friable and non -friable products and materials that do not fit in any of the above two categories such as resilient floor 3 IEa.. U PRE A U U U VERITAS covering, baseboards, mastics, adhesives, roofing material, caulking, glazing, and siding. This category also contains wallboard, joint compound, and ceiling tile. 2.5.3 Analysis Bureau Veritas collected 56 samples of suspect ACM which were analyzed using Polarized Light Microscopy (PLM), following the USEPA PLM method USEPA/60OR-93/116 (July 1993) and USEPA method 600/M4-82-020. The PLM analyses were conducted by Bureau Veritas' accredited laboratory located in Kennesaw, Georgia. Bureau Veritas' laboratory is accredited for PLM analysis by the National Institute of Standards and Technology (NIST) National Voluntary Laboratory Accreditation Program (NVLAP). The NVLAP laboratory accreditation certificate is included in Appendix B. Any material that contains greater than one (1) percent asbestos is considered an ACM and must be handled according to Occupational Safety and Health Administration (OSHA), USEPA, and applicable state and local regulations. The USEPA National Emission Standards for Hazardous Air Pollutants (NESHAP) 40 CFR 61, Subparts A and M has a requirement related to assessment of suspect ACM in buildings. When the asbestos content of a friable material is visually estimated by PLM to be detectable but less than ten (10) percent, your firm may elect to (1) assume the amount is greater than one (1) percent and treat the material as asbestos - containing or (2) require verification of the amount by the PLM point counting technique. If the results obtained by point counting and visual estimation are different, the point count result must be used. When no asbestos is detected by PLM, point counting is not required. For non -friable materials, when the amount of asbestos in the sample material is reported as "None -Detected" or "Trace Asbestos" by PLM analysis, due to the difficulty in analyzing "small, thin fibers" associated with vinyl/asphaltic or resinous bound materials (such as floor tile or roofing materials), Bureau Veritas recommends that these types of materials, which were reported as non -asbestos by PLM, be analyzed using the Transmission Electron Microscopy (TEM)-Chaffield method. Copies of the laboratory analytical report and corresponding chains of custody are included in Appendix A. Results are reported in percent asbestos by volume and indicate the types of asbestos. Other common non -asbestos components may also be noted on the analytical reports. 2.5.4 Assessment Bureau Veritas also evaluated the condition, accessibility and friability of the suspect ACM according to the following ratings: 1. Condition, as good (G), fair (F), or poor (P) 2. Friability, as friable (F) 4 3.0 RESULTS Lists of the suspect ACM and sample results are provided in Table 1 at the end of this report. Of the 56 samples collected, 8 samples were found to be asbestos -containing (> 1 % asbestos) and 10 samples were found to have trace amounts of asbestos (<1 %). Additional ACM may be present in inaccessible or concealed spaces. These spaces include, but are not limited to, pipe chases, spaces between walls/ceilings/doors/floor cavities, interior of mechanical components, beneath foundation pads, etc. If future maintenance, renovation, and/or demolition activities make these areas accessible, Bureau Veritas recommends that a thorough assessment of these spaces be conducted at that time to identify and confirm the presence or absence of additional ACM. Until then, all such unidentified materials should be treated as assumed ACM in accordance with OSHA 29 CFR 1926.1101. Materials containing one percent or less asbestos are regulated by the Washington State Department of Labor and Industries for worker protection purposes only and are not regulated to the same degree as materials containing greater than one percent asbestos (asbestos - containing materials). 4.0 APPLICABLE REGULATIONS AND GUIDELINES As indicated in Section 3, ACM was identified during Bureau Veritas' assessment. In addition, since ACM was identified, the following summaries of regulations applicable to ACM are included. 4.1 RENOVATION AND DEMOLITION (PUGET SOUND CLEAN AIR AGENCY (PSCAA) The Puget Sound Clean Air Agency (PSCAA) regulates asbestos removal and building demolition as it relates to air pollution. Their guidelines are based upon regulations of National Emissions Standards for Hazardous Air Pollutants (NESHAP). Under PSCAA regulations, it is unlawful to conduct demolition or renovation of any building without an asbestos survey conducted by an AHERA building inspector. The summary of the asbestos survey must be posted on site or communicated in writing to all persons who may come in the contact with the material. PSCAA conducts compliance inspections on selected asbestos abatement projects and may fine for violations. The PSCAA regulations also require the submittal of a notification form and fee prior to ACM removal and building demolition projects for friable asbestos -containing materials. 4.2 EMPLOYEE EXPOSURE WASHINGTON STATE DEPARTMENT OF LABOR AND INDUSTRIES (L&I) WAC 296-62-077 THROUGH 296-62-07755 AND WAC 296-65 L&I regulates' employee exposure to asbestos. The L&I asbestos standards for general industry and for construction mandate a permissible exposure limit (PEL) of 0.1 fibers [equal to or longer than five (5) micrometers] per cubic centimeter of air (fibers/cc) determined as an eight (8)-hour, time -weighted average (TWA) and an excursion limit of one (1) fiber/cc as a thirty (30)-minute TWA. Also, for asbestos removal or renovation involving ACM, the Washington Administrative Codes requires that specific procedures be followed, including enclosure of the work area, to control 5 ' L10 VAPRIA'U" V E, PRIl T �'A � S asbestos exposure of building occupants as well as employees involved in abatement or renovation activities. If ACM are managed in place, the L&I Asbestos Construction Standard apply to employees who may contact or disturb ACM during their work shift. Maintenance and custodial workers may be affected. The following are selected L&I definitions regarding asbestos work: Class I asbestos work means activities involving the removal of TSI and surfacing ACM and assumed ACM. Class 11 asbestos work means activities involving the removal of ACM which is not thermal system insulation or surfacing material. This includes, but is not limited to, the removal of asbestos -containing wallboard, floor tile and sheeting, roofing and siding shingles, and construction mastics. • Class III asbestos work means repair and maintenance operations, where "ACM", including TSI and surfacing ACM and assumed ACM, is likely to be disturbed. • Class IV asbestos work means maintenance and custodial activities during which employees contact but do not disturb ACM or assumed ACM and activities to clean up dust, waste and debris resulting from Class 1, 11, and III activities. • Intact means that the ACM has not crumbled, been pulverized, or otherwise deteriorated so that asbestos is no longer likely to be bound with its matrix. A submittal of a notification form is required ten days prior to start of abatement; however there are no fees involved. L&I conducts compliance inspections on selected asbestos abatement projects and may fine for violations. 4.3 EMPLOYEE EXPOSURE During the demolition or renovation of this structure, Washington L&I regulates employee exposure to asbestos. It is the responsibility of the building owner to provide an asbestos survey to companies providing bids or working on this project. The Contractors are responsible for communicating the hazards to their employees and performing all work in accordance with applicable regulations. The Washington L&I asbestos standards for general industry and construction mandate a permissible exposure limit (PEL) of 0.1 fibers per cubic centimeter of air (fibers/cc) determined as an 8-hour, time -weighted average (TWA) and an excursion limit of 1.0 fiber/cc as a 30-minute TWA. Prior to building demolition, the asbestos -containing materials must be removed from a building by a certified Asbestos removal Contractor. The Asbestos Contractor must submit all proper notifications and follows applicable rules. During the abatement, the Washington State Department of Labor and Industries (L&I) regulates inspection of the building, notification of removals, worker practices and procedures, disposal and final air clearance levels. If the building is renovated, any ACM which is impacted must be removed in accordance with applicable regulations. R P MU 'B:U REA U VERITAS 5.0 CONCLUSIONS AND RECOMMENDATIONS Where ACM and/or assumed ACM are present, actions should be taken to prevent fiber release and to minimize exposure of building occupants and maintenance employees to asbestos fibers. As presented in Section 3.0, results of our assessment indicate that asbestos is present in materials in the building. The following are Bureau Veritas' recommendations for management of these ACM. 1 . Bureau Veritas recommends that all the ACM identified in this report be maintained under a written asbestos Operations and Maintenance program, by suitably trained personnel, until renovation necessitates removal or until the building is (are) demolished. 2. Subcontractors and employees working within the on -site building should be made aware of the locations of the ACM and the possibility of concealed suspect ACM that could be found during renovation/demolition activities. They should be advised to not disturb the identified ACM or suspect ACM. 3. Any concealed building materials discovered during demolition activities, which are suspected to contain asbestos, should be sampled by an AHERA-accredited asbestos building inspector and analyzed by a NVLAP-accredited laboratory to confirm the presence of asbestos prior to the disturbing such materials. If the materials are found to contain asbestos, Washington L&I, USEPA, and PSCAA regulations will apply. 4. Bureau Veritas recommends friable materials containing < 1 % (trace) asbestos be further analyzed using the 400 Point Counting Method. 5. For non -friable materials, PLM analysis of some non -friable materials, such as vinyl floor tile, may yield false negative results. Therefore, Bureau Veritas recommends semi - quantitative analysis of these materials by transmission electron microscopy (TEM). 6. The manufacture and import of miscellaneous materials, such as vinyl floorings, mastics, roofing materials, etc., which may contain asbestos, have not been prohibited by the USEPA. As a result, any future replacement materials should be checked for the presence of asbestos prior to installation. The following recommendations should be followed for renovation/demolition projects including contracting the services of an environmental consultant to monitor/document that the demolition contractor activities comply with Washington L&I, USEPA, and PSCAA requirements. 1 . Provide the Executive Summary of this report to any contractor performing or bidding on work in this building. 2. The building owner should make available a copy of this report and provide a copy to the Contractors performing work which impact the asbestos materials should perform work in accordance with applicable regulations. 3. An AHERA-accredited Project Designer should prepare technical specifications for the proper removal, handling, and disposal requirements for this project. 7 U V" Is 092 4. During renovation and demolition operations, materials may be uncovered which are different from those accessible for sampling during this assessment. Personnel in charge of the demolition should be alerted to note materials uncovered during these operations that differ substantially from those included in this assessment. If additional suspect asbestos -containing materials are found, sampling and analysis should be conducted by certified personnel to determine if the materials contain asbestos. 5. An environmental consultant should perform air monitoring for asbestos to comply with Washington State regulations. 6.0 LIMITATIONS OF THIS REPORT The results, findings, conclusions, and recommendations expressed in the report are based only on conditions that were noted during the August 13, 2008, Bureau Veritas' inspection of the Prestige Care and Rehabilitation of Edmonds in Edmonds, Washington. Bureau Veritas' selection of sample locations and frequency of sampling was based on Bureau Veritas' observations and the assumption that like materials in the same area are homogeneous in content. The report is designed to aid the building owner, architect, construction manager, general contractors, and potential asbestos abatement contractors in locating ACM. Under no circumstances is the report to be utilized as a bidding document or as a project specification document since it does not have all the components required to serve as an Asbestos Project Design document or an Abatement Workplan. The quantities of ACM identified in this report are only estimates and should not be used for bidding or developing costs for abatement. It should be the responsibility of the asbestos abatement contractor to calculate actual quantities and develop removal costs accordingly. Our professional services have been performed, our findings obtained, and our conclusions and recommendations prepared in accordance with customary principles and practices in the fields of environmental science and engineering. This statement is in lieu of other statements either expressed or implied. This report does not warrant against future operations or conditions, nor does it warrant against operations or conditions present of a type or at a location not investigated. A #��S;u WE` X U#1 ITAV I T V E PRA S' The scope of services performed in execution of this evaluation may not be appropriate to satisfy the needs of other users, and use or re -use of this document or the findings, conclusions, or recommendations is at the risk of said user.

The total site is 2.29 acres. Project activities will include construction of the building, parking, landscaping, and utilities. In its existing condition, the site is fully developed. There is already a 35669 square foot assisted living facility and associated parking on the site. The existing building, parking, and landscaping will be demolished. in the developed condition, the project will add a building with a footprint of approximately 1.1 acres, 0.07 acres of sidewalks, and 0.70 acres of parking. The stormwater will be handled using a detention vault and stormfilter designed to meet flow control and water quality standards. The codes referenced in the design of this project were the City of Edmonds Stormwater Code Supplement and the Department of Ecology Stormwater Management Manualfor Western Washington, henceforth referred to in this report as Stormwater Supplement and Stormwater Manual, respectively. This report is based on the steps recommended in the Stormwater Supplement. The site qualifies as a Large Site Project per ECDC Chapter 18.30. It was determined that the project is required to address Minimum Requirements I through 11. In the following sections, this report will discuss existing conditions, off -site conditions, drainage design, stormwater control, erosion control, special reports, permits, and maintenance for the proposed project. 2504 th Ave South, Suite 200 0 Edmonds, WA 98020 ENGINEERING Stormwater Site Plan Report CG Project #13073.20 r-7 L -..� 0 TAW- I.MW C% 177 J r 4- 4 r 13 4 L; T U Figure 1: Aerial photograph of project site. 0 ENGINEERING 2504 th Ave South, Suite 200 Edmonds, WA 98020 Stormwater Site Plan Report CG Project #13073.20 40 section 2: 0 Existing Conditions Summary Section // Summa Narrative Site Survey (11 x1 7) The proposed site is located just off 76 th Ave W at 2 loth St. SW in Edmonds, WA. It is a 2.29 acre lot that is fully developed, with a 35669 square foot building located on the property. The existing site primarily has low slopes of up to 2%. Surficial soils primarily consist of till. A detailed geotechnical report is provided in Section 7. The site is bordered by commercial buildings on the north and south, 76 th Ave W to the east, and a residential development to the west. 41M 2504 th Ave South, Suite 200 0 Edmonds, WA 98020 ENGINEERING Stormwater Site Plan Report CG Project #13073.20 0 Section 3: 0 Conditions and Requirements Summary The proposed project requires a Full Stormwater Site Plan. The site plan meets the following minimum requirements as specified by the Stormwater Supplement. Minimum Requirement #1: Preparation of Stormwater Site Plan Narrative Minimum Requirement #2: Construction Stormwater Pollution Prevention Plan (SWPPP) narrative: Minimum Requirement #3: Source control of pollution Minimum Requirement #4: Preservation of natural drainage systems and outfalls Minimum Requirement #5: On -site stormwater management Minimum Requirement #6: Runoff treatment Minimum Requirement #7: Flow control Minimum Requirement #8: Wetland Protection Minimum Requiremen #9: Operation and Maintenance Minimum Requirement #10: Offsite Analysis and Mitikation Minimum Requirement #11: Financial Liabilit 11M 2504 1h Ave South, Suite 200 0 Edmonds, WA 98020 ENGINEERING Stormwater Site Plan Report CG Project #13073.20 0 section 4: 0 Off Site Analysis and Mitigation The proposed project is located in the Halls Creek basin, one of the two easternmost basins in Edmonds. Figure 4.1: City of Edmonds Basin Map The upstream and downstream features were investigated on -site by the project engineer. Overall the site appears to take little to no upstream runoff from neighboring properties. The residences to the north of the site appear to have a well -functioning drainage system which conveys stormwater south toward 212 th Street. The residences near the northwest corners of the site convey stormwater north on 78 th Ave W and appear more in the Good Hope Pond basin than the map in Figure 4-1 would indicate. The properties to the north of the site appear to convey their stormwater toward 76 1h Ave W. The existing site, which has a detention system, albeit one designed when flow control requirements were significantly less stringent, conveys its stormwater toward a catch basin on 76 th Ave W, where it then ties into the storm main which is located at the center of the 76 th Ave Wand2 loth Street SW intersection. The developed site proposes to follow this same drainage path, with significantly less stormwater due to the increased detention size yet relatively similar impervious area numbers. 4= 11M 2504 th Ave South, Suite 200 ENGINEERING Edmonds, WA 98020 Stormwater Site Plan Report CG Project #13073-20 0 Figure 4.2: Downstream Path from Site r 10.1 Figure 4.2 shows the path of the downstream flows. Flows run down 2 loth Street SW for approximately 900 feet downstream of the intersection. As can be seen in the picture in Figure 4.3,2 loth Street appears to have a good slope (estimated at about 7%) and should be expected to function well. City mapping programs indicate this line to be 12" diameter, which is confirmed within the extents of the project's survey. At manhole 10-19, the conveyance turns south, and runs toward 212 th in a 36" diameter storm pipe. This marked the end of the quarter mile downstream walk, with no problems observed or additional mitigations expected. The site does not discharge into a wetland either directly or indirectly, so Minimum Requirement #8 does not apply. 4W 2504 th Ave South, Suite 200 0 Edmonds, WA 98020 ENGINEERING Stormwater Site Plan Report CG Project #13073.20 0 0 Figure 4.3: Looking West, at site, from 210' (green paint indicates storm main) 0 ENGINEERING 2504 Ih Ave South, Suite 200 Edmonds, WA 98020 Stormwater Site Plan Report CG Project #13073.20 of Section 5: Drainage Design / Permanent Stormwater Control Plan Section VSumma Existing Site Hydrology Developed Site Hydrology Performance Standards Flow Control System Water Quality System A. Existing Site Hydrology: The area being considered is the entire site as represented in the Existing Conditions Summary (Section 2). The site was modeled as flat till forest (type C) for the WWHM calculations based on the geotechnical study. This is due to the requirement to match the historic durations of the site to the developed durations from the site; via flow control measures described in Part C of this chapter. WWHM reports for existing and developed conditions are included at the end of this chapter. Pervious Area Flat Forest: 2.29 acres Total: 2.29 acres Peak flows for the predeveloped site were as follows: 100 year 0.1071 cfs 50 year 0.0999 cfs 25 year 0.0912 cfs 10 year 0.0768 cfs 5 year 0.0629 cfs 2 year 0.0383 cfs B. -Developed Site Hydrology: For the developed condition the entire site was modeled as one basin. Pervious areas were modeled as till (type C) based on the geotechnical study. All landscaping was modeled as flat lawn. Pervious Areas Landscaping: 0.3927 acres Total: 0.3927 acres Impervious Areas Building: 1.094 acres Sidewalks: 0.0994 acres Parking: 0.7039 acres Total: 1.8973 acres 4M 2504 1h Ave South, Suite 200 0 Edmonds, WA 98020 ENGINEERING Stormwater Site Plan Report CG Project #13073.20 0 Peak flows (prior to detention) were as follows: 100 year 1.1758 cfs 50 year 1.0436 cfs 25 year 0.9188 cfs 10 year 0.7622 cfs 5 year 0.6471 cfs 2 year 0.4873 cfs C. Performance Standards: This project is required to meet Minimum Requirements 5, 6 and 7 for on site stormwater management, runoff treatment and flow control as outlined by the Stormwater Supplement. Specifically for this site, we will meet the duration standard and the Phosphorous Water Quality Treatment Menu. On -site Stormwater Management is met by providing compost amended soil in all disturbed pervious areas per the requirements of BMP T5.13 in the Stormwater Manual, Volume V, Chapter 5. Infiltration is not feasible per the geotechnical report, and the amount of impervious areas makes dispersion techniques infeasible. D. Flow Control System: All stormwater from the site will be routed through catch basins to a detention vault located under the parking lot to the south of the building. The vault will consist of two 20-foot wide cells, each 132 feet long. The vault will be 7 feet deep: 6 feet of live storage, 0.5 feet of dead storage, and 0.5 feet of freeboard. The flow control assembly will consist of an 18-inch standpipe fitted with a Thirsty Duck flow control mechanism. Details for this structure are provided following the calculations. Peak flows (with detention) were as follows: 100 year 0.1376 cfs; 50 year 0. 1043 cfs; 25 year 0.0783 cfs 10 year 0.0525 cfs 5 year 0.0378 cfs 2 year 0.0227 cfs In addition to meeting the flow duration standard (as indicated in the included WWHM output, the City of Edmonds also requires that peak flows not exceed 0.07, 0.14, and 0.33 cfs per acre of impervious surface for the 2, 10, and 100 year storms respectively. As seen in the table above, the project is well under these requirements. E. Water Quality System: The site will add 0.70 acres of pollution -generating impervious surfaces, well over the 5,000-square foot threshold that triggers the requirement. 4M 2504 th Ave South, Suite 200 ENGINEERING Edmonds, WA 98020 Stormwater Site Plan Report CG Project #13073.20 0 0 This site requires phosphorous treatment. Two Oldcastle Perk Filter assemblies are provided upstream of the detention vault to treat runoff from the parking lot and driveway. The Perk Filters were sized using WWHM's water quality flow rate.

Conveyance System Design The stormwater to the site is conveyed using PVC pipes, which have been sized within this section. Calculations for the conveyance design were performed using the Rational Method for the 25-Year, 24-Hour Storm. All conveyance pipes were sized to match the worst condition, which is the pipe from Catch Basin 6 to the detention vault. 8 inch and 12 inch diameter pipes will convey the stormwater on site to the detention vault, and from the detention vault to the storm sewer. The pipes connecting catch basin 4 to catch basin 6, the pipe connecting catch basin 6 to the detention vault, and the pipes from the detention vault to catch basin 10 will be 12 inch diameter PVC pipes. The rest of the pipes on the site will be 8" PVC. The lowest condition is a pipe with a 0.5% slope, but generally the pipes will have greater slopes. Given these conservative conditions, the pipes still convey the 25 year storm adequately. See the following pages of this report for calculations. The riser pipe for the detention vault will be 18 inches in diameter and must convey the 100-year un-cletained flow of 1.16 cfs. As can be seen by the following calculations, the riser pipe will adequately convey this flow rate (as an 18" inch diameter pipe would adequately convey the flow even were it laid at 0.5%, nearly horizontal). Downstream of the riser the pipe is 10" at 0.5%, which will convey 1.55 cfs. 11M 2504 th Ave South, Suite 200 0 Edmonds, WA 98020 ENGINEERING E 0 1� Prestige Care THIRSTY DUCK TD 248/184SERIES STAGE VS.

The site is located at 21008 76 1h Ave W in Edmonds. The existing site is a 2.29- acre lot with an existing 35669-square foot building, parking, and landscaping. The proposed development consists of the construction of a new assisted living building complex that will include 80 units, parking, and landscaping. Construction activities will include demolition, excavation, grading, relocation of onsite services/utilities, and construction of a 48385-square foot building. The purpose of this SWPPP is to describe the proposed construction activities and all temporary and permanent erosion and sediment control (TESC) measures, pollution prevention measures, inspection/monitoring activities, and recordkeeping that will be implemented during the proposed construction project. The objectives of the SWPPP are to: Implement Best Management Practices (BMPs) to prevent erosion and sedimentation, and to identify, reduce, eliminate or prevent stormwater contamination and water pollution from construction activity. 2. Prevent violations of surface water quality, ground water quality, or sediment management standards. 3. Prevent, during the construction phase, adverse water quality impacts including impacts on beneficial uses of the receiving water by controlling peak flow rates and volumes of stormwater runoff at the Permittee's outfalls and downstream of the outfalls. This SWPPP was prepared using the Ecology SWPPP Template downloaded from the Ecology website on October 1, 2013. This SWPPP was prepared based on the requirements set forth in the Construction Stormwater General Permit, Stormwater Management Manual for Western Washington (SWMMWW 2005) and in the Stormwater Management Manual for Eastern Washington (SWMMEW 2004). The report is divided into seven main sections with several appendices that include stormwater related reference materials. The topics presented in the each of the main sections are: Section 1 — INTRODUCTION. This section provides a summary description of the project, and the organization of the SWPPP document. Section 2 — SITE DESCRIPTION. This section provides a detailed description of the existing site conditions, proposed construction activities, and calculated stormwater flow rates for existing conditions and post — construction conditions. Stormwater Pollution Prevention Plan Section 3 — CONSTRUCTION BMPs. This section provides a detailed description of the BMPs to be implemented based on the 12 required elements of the SWPPP (SWMMEW 2004). Section 4 — CONSTRUCTION PHASING AND BMP IMPLEMENTATION. This section provides a description of the timing of the BMP implementation in relation to the project schedule. Section 5 — POLLUTION PREVENTION TEAM. This section identifies the appropriate contact names (emergency and non -emergency), monitoring personnel, and the onsite temporary erosion and sedimentation control inspector Section 6 — INSPECTION AND MONITORING. This section provides a description of the inspection and monitoring requirements such as the parameters of concern to be monitored, sample locations, sample frequencies, and sampling methods for all stormwater discharge locations from the site. Section 7 — RECORDKEEPING. This section describes the requirements for documentation of the BMP implementation, site inspections, monitoring results, and changes to the implementation of certain BMPs due to site factors experienced during construction. Supporting documentation and standard forms are provided in the following Appendices: Appendix A — Site plans Appendix B — Construction BMPs Appendix C — Alternative Construction BMP list Appendix D — General Permit Appendix E — Site Log and Inspection Forms Appendix F — Engineering Calculations L Stormwater Pollution Prevention Plan 2.0 Site Description 2.1 Existing Conditions The proposed site is located just off 76" Ave W at 210" St SW in Edmonds, WA. Asitevicinity map and coordinates are provided in Appendix A. The site is 2.29 acres in size and includes 35669-square foot building, parking, and landscaping. The topography of the site and surrounding properties is flat, with slopes less than 2%. Surficial soils primarily consist of till, preventing the use of infiltration facilities 2.2 Proposed Construction Activities The proposed development includes the construction of an 80-unit senior apartment building and its associated parking, driveways, landscaping, and utilities. The proposed building will be located on the northern half of the site. Runoff from the site will be controlled using a detention vault, and filtered with a Contech Stormfilter. Construction activities will include site preparation, TESC installation, demolition of existing building and parking lot, excavation for the building foundations and detention vault, poured concrete foundations, concrete tilt -up building construction, site -wide grading, and asphalt paving. The schedule and phasing of BMPs during construction is provided in Section 4.0. Stormwater runoff volumes were calculated using the Western Washington Hydrology Model (WWHM). The temporary sedimentation pond that will be used during construction was designed using the 2-year storm event since construction will not occur over a long time -frame (approximately one year). The pre- and post -construction peak flows were compared using the 2, 10, and 100 year storm events. Conveyance systems were designed using the 25 year storm. After the building is constructed and all new utilities are installed, the site will be graded and paved. The following summarizes details regarding site areas: a Total site area: 2.29 acres 0 Percent impervious area before construction: 74% 0 Percent impervious area after construction: 81 % 0 * 0 Disturbed area during construction: 2.29 acres Stormwater Pollution Prevention Plan Disturbed area that is characterized as impervious (i.e., access roads, staging, parking): 1.85 acres 2-year stormwater runoff peak flow prior to construction (existing): .0383 cfs 1 0-year stormwater runoff peak flow prior to construction (existing): .0768 cfs 0 2-year stormwater runoff peak flow during construction: .0195 cfs M I 0-year stormwater runoff peak flow during construction: .0476 cfs 0 2-year stormwater runoff peak flow after construction: .0195 efs 0 1 0-year stormwater runoff peak flow after construction: .0476 cfs All stormwater flow calculations are provided in Appendix F. I is 0 Stormwater Pollution Prevention Plan 0 3.0 Construction Stormwater BMPs 3.1 The 12 BMP Elements 3.1.1 Element #1 — Mark Clearing Limits To protect adjacent properties and to reduce the area of soil exposed to construction, the limits of construction will be clearly marked before land -disturbing activities begin. Trees that are to be preserved, as well as all sensitive areas and their buffers, shall be clearly delineated, both in the field and on the plans. In general, natural vegetation and native topsoil shall be retained in an undisturbed state to the maximum extent possible. The BMPs relevant to marking the clearing limits that will be applied for this project include: High Visibility Plastic or Metal Fence (BMP C 103) Clearing limits will be marked with a high visibility fence as shown on the C2.1 plan in the civil drawings. Alternate BMPs for marking clearing limits are included in Appendix C as a quick reference tool for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during construction to satisfy the requirements set forth in the General NPDES 41 Permit (Appendix D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or failing. 3.1.2 Element #2 — Establish Construction Access Construction access or activities occurring on unpaved areas shall be minimized, yet where necessary, access points shall be stabilized to minimize the tracking of sediment onto public roads, and wheel washing, street sweeping, and street cleaning shall be employed to prevent sediment from entering state waters. All wash wastewater shall be controlled on site. The specific BMPs related to establishing construction access that will be used on this project include: Stabilized Construction Entrance (BMP C 105) A stabilized construction entrance will be added at the western edge of the site, and will help to prevent sediment tracking into the right of way. 0 Stormwater Pollution Prevention Plan Alternate construction access BMPs are included in Appendix C as a quick reference tool for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or failing. 3.1.3 Element #3 — Control Flow Rates In order to protect the properties and waterways downstream of the project site, stormwater discharges from the site will be controlled. The specific BMPs for flow control that shall be used on this project include: Sediment Trap (BMP` C240) The sediment trap will be located at the western edge of the site, near Hardie Ave SW. Sizing calculations are provided in Appendix F Alternate flow control BMPs are included in Appendix C as a quick reference tool for the onsite & inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or failing. The project site is located west of the Cascade Mountain Crest. As such, the project must comply with Minimum Requirement 7 (Ecology 2005). In general, discharge rates of stormwater from the site will be controlled where increases in impervious area or soil compaction during construction -could lead to downstream erosion, or where necessary to meet local agency stormwater discharge requirements (e.g. discharge to combined sewer systems). 3.1.4 Element #4 — Install Sediment Controls All stormwater runoff from disturbed areas shall pass through an appropriate sediment removal BMP before leaving the construction site or prior to being discharged to an infiltration facility. The specific BMPs to be used for controlling sediment on this project include: 0 Silt Fence (BMP C233) Stormwater Pollution Prevention Plan 0 Sediment Trap (BMP C240) A silt fence will be installed- around the downhill perimeter of the site as shown on the C2.1 Plan. The sediment trap will be installed as indicated in Element #3's description. Alternate sediment control BMPs are included in Appendix C as a quick reference tool for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or failing. In addition, sediment will be removed from paved areas in and adjacent to construction work areas manually or using mechanical sweepers, as needed, to minimize tracking of sediments on vehicle tires away from the site and to minimize washoff of sediments from adjacent streets in runoff. Whenever possible, sediment laden water shall be discharged into onsite, relatively level, vegetated areas (BMP C240 paragraph 5, page 4-102). 1 In some cases, sediment discharge in concentrated runoff can be controlled using permanent stormwater BMPs (e.g., infiltration swales, ponds, trenches). Sediment loads can limit the effectiveness of some permanent stormwater BMPs, such as those used for infiltration or biofiltration; however, those BMPs designed to remove solids by settling (wet ponds or detention ponds) can be used during the construction phase. When permanent stormwater BMPs will be used to control sediment discharge during construction, the structure will be protected from excessive sedimentation with adequate erosion and sediment control BMPs. Any accumulated sediment shall be removed after construction is complete and the permanent stormwater BMP will be restabilized with vegetation per applicable design requirements once the remainder of the site has been stabilized. 3.1.5 Element #5 — Stabilize Soils Exposed and unworked soils shall be stabilized with the application of effective BMPs to prevent erosion throughout the life of the project. The specific BMPs for soil stabilization that shall be used on this project include: Temporary and Permanent Seeding (BMP C120) Dust Control (BMP C140) 0 Stormwater Pollution Prevention Plan 0 The ESC Supervisor shall be familiar with BMPs for soil stabilization and dust control and implement these BMPs where needed on the proposed site. Alternate soil stabilization BMPs are included in Appendix C as a quick reference tool for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or failing. The project site is located west of the Cascade Mountain Crest. As such, no siols shall remain exposed and unworked for more than 7 days during the dry season (May I to September 30) and 2 days during the wet season (October I to April 30). Regardless of the time of year, all soils shall be stabilized at the end of the shift before a holiday or weekend if needed based on weather forecasts. The project site is located west of the Cascade Mountain Crest. As such, no soils shall remain exposed and unworked for more than 7 days during the dry season (May 1 to September 30) and 2 days during the wet season (October 1 to April 30). Regardless of the time of year, all soils shall be stabilized at the end of the shift before a holiday or weekend if needed based on weather forecasts. In general, cut and fill slopes will be stabilized as soon as possible and soil stockpiles will be temporarily covered with plastic sheeting. All stockpiled soils shall be stabilized from erosion, protected with sediment trapping measures, and where possible, be located away from storm drain inlets, waterways, and drainage channels. 3.1.6 Element #6 — Protect Slopes All cut and fill slopes will be designed, constructed, and protected in a manner than minimizes erosion. The following specific BMPs will be used to protect slopes for this project: Temporary and Permanent Seeding (BMP C120) Interceptor Dike and Swale (BMP C200) Check Darns (BMP C207) 0 0 Stormwater Pollution Prevention Plan Interceptor Swales with check dams are shown on the C2.1 plan to show the contractor how to direct flows to the sediment trap during contract. These facilities should be relocated as warranted during construction. Alternate slope protection BMPs are included in Appendix C as a quick reference tool for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or failing. 3.1.7 Element #7 — Protect Drain Inlets All storm drain inlets and culverts made operable during construction shall be protected to prevent unfiltered or untreated water from entering the drainage conveyance system. However, the first priority is to keep all access roads clean of sediment and keep street wash water separate from entering storm drains until treatment can be provided. Storm Drain Inlet Protection (BMP C220) will be implemented for all drainage inlets and culverts that could potentially be impacted by sediment -laden runoff on and near the project site. The following inlet protection measures will be applied on this project: Drop Inlet Protection 0 Excavated Drop Inlet Protection 0 Block and Gravel Drop Inlet Protection 0 Gravel and Wire Drop Inlet Protection 0 Catch Basin Filters 0 Alternative BMP not included in the SWMMWW (2005) or SWMMEW (2004) Inlet protection should be provided as shown on the C2.1 Plan.Drop Inlet Protection 0 Excavated Drop Inlet Protection 0 Block and Gravel Drop Inlet Protection 0 0 Gravel and Wire Drop Inlet Protection 0 Stormwater Pollution Prevention Plan Catch Basin Filters Alternative BMP not included in the SWMMWW (2005) or SWMMEW (2004) Curb Inlet Protection Culvert Inlet Protection If the BMP options listed above are deemed ineffective or inappropriate during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix D), or if no BMPs are listed above but deemed necessary during construction, the Certified Erosion and Sediment Control Lead shall implement one or more of the alternative BMP inlet protection options listed in Appendix C. 3.1.8 Element #8 — Stabilize Channels and Outlets Where site runoff is to be conveyed in channels, or discharged to a stream or some other natural drainage point, efforts will be taken to prevent downstream erosion. The specific BMPs for channel and outlet stabilization that shall be used on this project include: 0 No BMPs to be implemented Alternate channel and outlet stabilization BMPs are included in Appendix C as a quick reference tool for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or failing. The project site is located west of the Cascade Mountain Crest. As such, all temporary on -site conveyance channels shall be designed, constructed, and stabilized to prevent erosion from the expected peak 10 minute velocity of flow from a Type 1 A, 10-year, 24-hour recurrence interval storm for the developed condition. Alternatively, the I 0-year, 1 -hour peak flow rate indicated by an approved continuous runoff simulation model, increased by a factor of 1.6, shall be used. Stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent streambanks, slopes, and downstream reaches shall be provided at the outlets of all conveyance systems. The project site is located west of the Cascade Mountain Crest. As such, all temporary on -site conveyance channels shall be designed, constructed, and stabilized to prevent erosion from the expected peak 10 minute velocity of flow from a Type 1 A, 1 0-year, 24-hour recurrence interval 10 Stormwater Pollution Prevention Plan storm for the developed condition. Alternatively, the I 0-year, I -hour peak flow rate indicated by an approved continuous runoff simulation model, increased by a factor of 1.6, shall be used. Stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent streambanks, slopes, and downstream reaches shall be provided at the outlets of all conveyance systems. 3.1.9 Element #9 — Control Pollutants All pollutants, including waste materials and demolition debris, that occur onsite shall be handled and disposed of in a manner that does not cause contamination of stormwater. Good housekeeping and preventative measures will be taken to ensure that the site will be kept clean, well organized, and free of debris. If required, BMPs to be implemented to control specific sources of pollutants are discussed below. Sanitary wastewater: Portable sanitation facilities will be firmly secured, regularly maintained, and emptied when necessary. Wheel wash or tire bath wastewater shall be discharged to a separate on =site treatment system or to the sanitary sewer as part of Wheel Wash implementation (BMP C 106) The facility does not require a Spill Prevention, Control, and Countermeasure (SPCC) Plan under the Federal regulations of the Clean Water Act (CWA). 3.1.10 Element #10 — Control Dewatering There will be no dewatering as part of this construction project. 3.1.11 Element #11 —Maintain BMPs All temporary and permanent erosion and sediment control BMPs shall be maintained and repaired as needed to assure continued performance of their intended fimetion. Maintenance and repair shall be conducted in accordance with each particular BMPs specifications (attached). Visual monitoring of the BMPs will be conducted at least once every calendar week and within 24 hours of any stormwater or non-stormwater discharge from the site. If the site becomes inactive, and is temporarily stabilized, the inspection frequency will be reduced to once every month. All temporary erosion and sediment control BMPs shall be removed within 30 days after the final site stabilization is achieved or after the temporary BMPs are no longer needed. Trapped sediment shall be removed or stabilized on site. Disturbed soil resulting from removal of BMPs or vegetation shall be permanently stabilized. I I Stormwater Pollution Prevention Plan 40 3.1.12 Element #12 — Manage the Project Erosion and sediment control BMPs for this project have been designed based on the following principles: Design the project to fit the existing topography, soils, and drainage patterns. N Emphasize erosion control rather than sediment control. 0 Minimize the extent and duration of the area exposed. 0 Keep runoff velocities low. 0 Retain sediment on site. 0 Thoroughly monitor site and maintain all ESC measures. 0 Schedule major earthwork during the dry season. In addition, project management will incorporate the key components listed below: is As this project site is located west of the Cascade Mountain Crest, the project will be managed according to the following key project components: Phasing of Construction The construction project is being phased to the extent practicable in order to prevent soil erosion, and, to the maximum extent possible, the transport of sediment from the site during construction. Revegetation of exposed areas and maintenance of that vegetation shall be an integral part of the clearing activities during each phase of construction, per the Scheduling BMP (C 162). Seasonal Work Limitations From October 1 through April 30, clearing, grading, and other soil disturbing activities shall only be permitted if shown to the satisfaction of the local permitting authority that silt -laden runoff will be prevented from leaving the site through a combination of the following: Site conditions including existing vegetative coverage, slope, soil type, and proximity to receiving waters; and 12 Stormwater Pollution Prevention Plan 0 13 Limitations on activities and the extent of disturbed areas; and 11 Proposed erosion and sediment control measures. Based on the information provided and/or local weather conditions, the local permitting authority may expand or restrict the seasonal limitation on site disturbance. The following activities are exempt from the seasonal clearing and grading limitations: 13 Routine maintenance and necessary repair of erosion and sediment control BMPs; 11 Routine maintenance of public facilities or existing utility structures that do not expose the soil or result in the removal of the vegetative cover to soil; and Activities where there is 100 percent infiltration of surface water runoff within the site in approved and installed erosion and sediment control facilities. 0 Coordination with Utilities and Other Jurisdictions Care has been taken to coordinate with utilities, other construction projects, and the local jurisdiction in preparing this SWPPP and scheduling the construction work. Inspection and Monitoring All BMPs shall be inspected, maintained, and repaired as needed to assure continued performance of their intended ftinction. Site inspections shall be conducted by a person who is knowledgeable in the principles and practices of erosion and sediment control. This person has the necessary skills to: 11 Assess the site conditions and construction activities that could impact the quality of stormwater, and 11 Assess the effectiveness of erosion and sediment control measures used to control the quality of stormwater discharges. A Certified Erosion and Sediment Control Lead shall be on -site or on -call at all times. 13 Stormwater Pollution Prevention Plan Whenever inspection and/or monitoring reveals that the BMPs identified in this SWPPP are inadequate, due to the actual discharge of or potential to discharge a significant amount of any pollutant, appropriate BMPs or design changes shall be implemented as soon as possible. Maintaining an Updated Construction SWPPP This SWPPP shall be retained on -site or within reasonable access to the site. The SWPPP shall be modified whenever there is a change in the design, construction, operation, or maintenance at the construction site that has, or could have, a significant effect on the discharge of pollutants to waters of the state. The SWPPP shall be modified if, during inspections or investigations conducted by the owner/operator, or the applicable local or state regulatory authority, it is determined that the SWPPP is ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from the site. The SWPPP shall be modified as necessary to include additional or modified BMPs designed to correct problems identified. Revisions to the SWPPP shall be completed within seven (7) days following the inspection. --- 3.2 Site Specific BNIPs Site specific BMPs are shown on the TESC Plan Sheets and Details in Appendix A. These site specific plan sheets will be updated annually. 3.3 Additional Advanced BMPs The following BMPs are advanced and are only recommended if construction activities are complex enough to warrant them, or if the site has the potential for significant impacts to water quality. The following BMPs are directed at "end of pipe" treatment for sedimentation issues related to turbid runoff from construction sites. Effective BMPs are most often the simple BMPs, and focus on the minimization of erosion before sedimentation is an issue. The following BMPs will most likely be implemented only after other BMP options are exhausted or if the construction activity is large and off site sedimentation or turbid runoff occurs or is inevitable. For BMP 250 written pre -approval through Ecology is required.

A site log book will be maintained for all on -site construction activities and will include: A record of the implementation of the SWPPP and other permit requirements; Site inspections; and, Stormwater quality monitoring. For convenience, the inspection form and water quality monitoring forms included in this SWPPP include the required information for the site log book. This SWPPP may function as the site log book if desired, or the forms may be separated and included in a separate site log book. However, if separated, the site log book but must be maintained on -site or within reasonable access to the site and be made available upon request to Ecology or the local jurisdiction. 6.1 Site Inspection All BMPs will be inspected, maintained, and repaired as needed to assure continued performance of their intended function. The inspector will be a Certified Erosion and Sediment Control Lead (CESCL) per BMP C160. The name and contact information for the CESCL is provided in Section 5 of this SWPPP. Site inspection will occur in all areas disturbed by construction activities and at all stormwater discharge points. Stormwater will be examined for the presence of suspended sediment, turbidity, discoloration, and oily sheen. The site inspector will evaluate and document the effectiveness of the installed BMPs and determine if it is necessary to repair or replace any of the BMPs to improve the quality of stormwater discharges. All maintenance and repairs will be documented in the site log book or forms provided in this document. All new BMPs or design changes will be documented in the SWPPP as soon as possible. 6.1.1 Site Inspection Frequency Site inspections will be conducted at least once a week and within 24 hours following any discharge from the site. For sites with temporary stabilization measures, the site inspection frequency can be reduced to once every month. 6.1.2 Site Inspection Documentation The site inspector will record each site inspection using the site log inspection forms provided in Appendix E. The site inspection log forms may be separated from this SVYTPP document, but 19 0 Stormwater Pollution Prevention Plan will be maintained on -site or within reasonable access to the site and be made available upon request to Ecology or the local jurisdiction. 6.2 Stormwater Quality Monitoring 6.2.1 Turbidity Monitoring requirements for the proposed project will include either turbidity or water transparency sampling to monitor site discharges for water quality compliance with the 2005 Construction Stormwater General Permit (Appendix D). Sampling will be conducted at all discharge points at least once per calendar week. Turbidity or transparency monitoring will follow the analytical methodologies described in Section S4 of the 2005 Construction Stormwater General Permit (Appendix D). The key benchmark values that require action are 25 NTU for turbidity (equivalent to 32 cm transparency) and 250 NTU for turbidity (equivalent to 6 cm transparency). If the 25 NTU benchmark for turbidity (equivalent to 32 cm transparency) is exceeded, the following steps will be conducted Ensure all BMPs specified in this SWPPP are installed and fanctioning as intended. 2. Assess whether additional BMPs should be implemented, and document modified BMPs in the SWPPP as necessary. 3. Sample discharge daily until the discharge is 25 NTU or lower. If the turbidity is greater than 25 NTU (or transparency is less than 32 cm) but less than 250 NTU (transparency greater than 6 cm) for more than 3 days, additional treatment BMPs will be implemented within 24 hours of the third consecutive sample that exceeded the benchmark value. Additional treatment BMPs to be considered will include, but are not limited to, off -site treatment, infiltration, filtration, and chemical treatment. If the 250 NTU benchmark for turbidity (or less than 6 cm transparency) is exceeded at any time, the following steps will be conducted: Notify Ecology by phone within 24 hours of analysis (see Section 5.0 of this SWPPP for contact information). 2. Continue daily sampling until the turbidity is less than 25 NTU (or transparency is greater than 32 cm) 20 Stormwater Pollution Prevention Plan 3. Initiate additional treatment BMPs such as off -site treatment, infiltration, filtration and chemical treatment within 24 hours of the first 250 NTU exceedance. 4. Implement additional treatment BMPs as soon as possible, but within 7 days of the first 250 NTU exceedance. 5. Describe inspection results and remedial actions taken in the site log book and in monthly discharge monitoring reports as described in Section 7.0 of this SVvTPP. 6.2.2 pH Stormwater runoff will be monitored for pH starting on the first day of any activity that includes more than 40 yards of poured or recycled concrete, or after the application of "Engineered Soils" such as, Portland cement treated base, cement kiln dust, or fly ash. This does no include fertilizers. For engineered soils, the pH monitoring period begins when engineered soils are first exposed to precipitation and continue until the area is fully stabilized. Stormwater samples will be collected daily from all points of discharge from the site and measured for pH using a calibrated pH meter, pH test kit, or wide range pH indicator paper. If the measured pH is 8.5 or greater, the following steps will be conducted: 1. Prevent the high pH water from entering storm d rains or surface water. 2. Adjust or neutralize the high pH water if necessary using appropriate technology such as CO2 sparging (liquid or dry ice). 3. Contact Ecology if chemical treatment other than CO2 sparging is planned. Sampling and monitoring for pH will occur during the phase of construction when concrete pouring will be conducted until fully cured (3 weeks from last pour) and discharges are documented to be below pH 8.5. Samples will be collected weekly at the sedimentation pond prior to discharge to surface water. Samples will be analyzed for pH using a calibrated pH meter and recorded in the site log book. The key benchmark pH value for ston-nwater is a maximum of 8.5. If a pH greater than 8.5 is measured in the sedimentation trap/pond(s) that has the potential to discharge to surface water, the following steps will be conducted: Prevent (detain) all discharges from leaving the site and entering surface waters or storm drains if the pH is greater than 8.5 2. Implement CO2 sparging or dry ice treatment in accordance with Ecology BMP C252. 21 0 0 Stormwater Pollution Prevention Plan Describe inspection results and remedial actions that are taken in the site log book and in monthly discharge monitoring reports as described in Section 7.0 of this SWPPP. 22 Stormwater Pollution Prevention Plan 0 7.0 Reporting and Recordkeeping 7.1 Recordkeeping 7.1.1 Site Log Book A site log book will be maintained for all on -site construction activities and will include: A record of the implementation of the SWPPP and other permit requirements; Site inspections; and, Stormwater quality monitoring.

Permittees may use the rating system below or develop alternative process designed to identify site -specific features which indicate that the site must be inspected prior to clearing and construction. Any alternative evaluation process must be documented and provide for equivalent environmental review. Step one is to determine if there is a sediment/erosion sensitive feature downstream of the development site. If there is such a site downstream complete step two, assessment of hydraulic nearness. If there is a sediment/erosion sensitive feature and it is hydraulically near the site then go to step three to determine the construction site sediment transport potential. �TEP I — Sediment/Erosion Sensitive Feature Identification Sediment/erosion sensitive features are areas subject to significant degradation due to the effect of sediment deposition or erosion. Special protection must be provided to protect them. Sediment/erosion sensitive features include but are not limited to: i. Salmonid bearing fresh water streams and their tributaries or freshwater streams that would be Salmonid bearing if not for anthropogenic barriers; ii. Lakes; NIA f iii. Category 1, 11, and III wetlands; iv. Marine near -shore habitat; V. Sites containing contaminated soils where erosion could cause dispersal of contaminants; and vi. Steep slopes (25% or greater) associated with one of the above features. Identify any sediment/erosion sensitive features, and proceed to step two. If there are none the assessment is complete. �TEP 2 — Hydraulic Nearness Assessment Sites are hydraulically near a feature if the pollutant load and peak quantity of runoff from the site will not be naturally attenuated before entering the feature. The conditions that render a site hydraulically near to a feature include, but are not limited to, the following: i. The feature or a buffer to protect the feature is within 200 feedt downstream of the site. ii. Runoff from the site is tight -lined to the feature or flows to the feature through a channel or ditch. A site is not hydraulically near a feature if one of the following takes place to provide attenuation before runoff from the site enters the feature: i. Sheet flow through a vegetated area with dense ground cover August 1, 201.3 AppendLy 7- Deternfinhil- Sediment Damuge Polenlial Page I q1'.)3 Western Washin�agton Phase H Municipal Storn7water Perinit ii. Flow through a wetland not included as a sensitive feature iii. Flow through a significant shallow or adverse slope, not in a conveyance channel, between the site and the sensitive feature. Identify any of the sediment/erosion sensitive features from step one that are hydraulically near the site, and proceed to step three. If none of the sediment/erosion sensitive features are hydraulically near the site the assessment is complete. tTEP 3 — Construction Site Sediment Tranmort Potential Using the worksheet below, determine the total points for each development site. Assign points based on the most critical condition that affects 10% or more of the site. If soil testing has been performed on site, the results should be used to determine the predominant soil type on the site. Otherwise, soil infon-nation should be obtained from the county soil survey to determine Hydrologic Soil Group (Table of Engineering Index Properties for step 1.13) and Erosion Potential (Table of Water Features for step LE) When using the county soil survey, the dominant soil type may be in question, particularly when the site falls on a boundary between two soil types or when one of two soil types may be present on a site. In this case, the soil type resulting in the most points on the rating system will be assumed unless site soil tests indicate that another soil type dominates the site. Use the point score from Step 3 to determine whether the development site has a high potential for sediment transport off of the site. Total Score Transport Ratin <1 00 Low �!100 High A high transport rating indicates a higher risk that the site will generate sediment contaminated runoff.

Hold regular meetings to review the overall a Pollution operation of the BNTS'. Establish responsibilities for inspections, Prevention operation and maintenance, and availability for emergency situations. Team Train all team members in the operation, maintenance and inspections of BNTs, and reporting procedures. 0 Promptly contain and clean up solid and liquid pollutant leaks and Good spills including oils, solvents, fuels, and dust from manufacturing Housekeeping operations on any exposed soil, vegetation, or paved area. Sweep paved material handling and storage areas regularly as needed, for the collection and disposal of dust and debris that could contaminate storrawater. Do not hose down pollutants from any area to the ground, storm drain, conveyance ditch, or receiving water unless necessary for dust control purposes to meet air quality regulations and unless the pollutants are conveyed to a treatment system approved by the local jurisdiction. Clean oils, debris, sludge, etc. from all BNIP systems regularly, including catch basins, settling/detention basins, oil/water separators, boomed areas, and conveyance systems, to prevent the contamination of stormwater. Refer to Appendix IV-D R-3 for references to assist in determining if a waste must be handled as hazardous waste. Promptly repair or replace all substantially cracked or otherwise damaged paved secondary containment, high -intensity parking and any other drainage areas, which are subjected to pollutant material leaks or spills. Promptly repair or replace all leaking connections, pipes, hoses, valves, etc. which can contaminate stormwater. The following are recommended additional good housekeeping BMTs: • Clean up pollutant liquid leaks and spills in impervious uncovered containment areas at the end of each working day. • Use solid absorbents, e.g., clay and peat absorbents and rags for cleanup of liquid spills/leaks, where practicable. • Recycle materials, such as oils, solvents, and wood waste, to the maximum extent practicable. 2-2 Volume W - Source Control BMPs February 2005 0 Preventive 0 Prevent the discharge of unpermitted liquid or solid wastes, process Maintenance wastewater, and sewage to ground or surface water, or to storm drains which discharge to surface water, or to the ground. 0 Do not connect floor drains in potential pollutant source areas to storm drains, surface water, or to the ground. • Conduct all oily parts cleaning, steam cleaning, or pressure -washing of equipment or containers inside a building, or on an impervious contained area, such as a concrete pad. Direct contaminated stormwater from such an area to a sanitary sewer where allowed by local sewer authority, or to other approved treatment. • Do not pave over contaminated soil unless it has been determined that ground water has not been and will not be contaminated by the soil. Call Ecology for assistance. • Construct impervious areas that are compatible with the materials handled. Portland cement concrete, asphalt, or equivalent material may be considered. • Use drip pans to collect leaks and spins from industrial/ commercial equipment such as cranes at ship/boat building and repair facilities, log stackers, industrial parts, trucks and other vehicles, which are stored outside. At industrial and commercial facilities, drain oil and fuel filters before disposal. Discard empty oil and fuel filters, oily rags and other oily solid waste into appropriately closed and properly labeled containers, and in compliance with the Uniform Fire Code. • For the storage of liquids use containers, such as steel and plastic drums, that are rigid and durable, corrosion resistant to the weather and fluid content, non -absorbent, water tight, rodent -proof, and equipped with a close fitting cover. • For the temporary storage of solid wastes contaminated with liquids or other potential pollutant materials use dumpsters, garbage cans, drums and comparable containers, which are durable, corrosion resistant, non -absorbent, non -leaking, and equipped with either a solid cover or screen cover to prevent littering. If covered with a screen, the container must be stored under a lean-to or equivalent structure. • Where exposed to storinwater, use containers, piping, tubing, pumps, fittings, and valves that are appropriate for their intended use and for the contained liquid. The following are recommended additional preventive maintenance BNTs: Where feasible, store potential storinwater pollutant materials inside a building or under -a cover and/or containment. February 2005 Volume IV - Source Control BMPs 2-3 Nfinimize use of toxic cleaning solvents, such as chlorinated solvents, and other toxic chemicals. • Use environmentally safer raw materials, products, additives, etc. such as substitutes for zinc used in rubber production. • Recycle waste materials such as solvents, coolants, oils, degreasers, and batteries to the maximum extent feasible. Refer to Appendix IV-C for recommendations on recycling or disposal of vehicle waste liquids and other waste materials. • Empty drip pans immediately after a spill or leak is collected in an uncovered area. • Stencil warning signs at stormwater catch basins and drains, e.g., "Dump no waste." Note: Evidence of stormwater contamination can include the presence of visible sheen, color, or turbidity in the runoff, or present or historical operational problems at the facility. Simple pH measurements with litmus or pH paper can be used to test for stormwater contamination in areas subject to acid or alkaline contamination. Spill Prevention 0 Immediately upon discovery, stop, contain, and clean up all spills. and Cleanup 0 If pollutant materials are stored on -site, have spill contairiment and cleanup kits readily accessible. 0 If the spill has reached or may reach a sanitary or a storm sewer, ground water, or surface water notify Ecology and the local sewer authority immediately. Notification must comply with and federal spill reporting requirements. -(See also record keeping at the end of this section and BNIPs for Spills of Oil and Hazardous Substances) 0 Do not flush absorbent materials or other spill cleanup materials to a storm drain. Collect the contaminated absorbent material as a solid and place in appropriate disposal containers. The following is a recommended additional BW: Place and maintain emergency spill containment and cleanup kit(s) at outside areas where there is a potential for fluid spills. These kits should be appropriate for the materials being handled and the size of the potential spill. Note: Ecology recommends that the kit(s) include salvage drums or containers, such as high density polyethylene, polypropylene or polyethylene sheet -lined steel; polyethylene or equivalent disposal bags; an emergency response guidebook; safety gloves/clothes/equipment; shovels or other soil removal equipment; and oil containment booms and absorbent pads; all stored in an impervious container. 0 2-4 Volume IV - Source Control BMPs February 2005 E Train all employees that work in pollutant source areas in identifying Employee pollutant sources and in understanding pollutant control measures, spill Training response procedures, and environmentally acceptable material handling practices - particularly those related to vehicle/equipment liquids such as fuels, and vehicle/equipment cleaning.

E 0 - 2�-6 Volume IV - Source Control BMPs February 2005 BMP T5.1 3 Post -Construction Soil Quality and Depth 0 Purpose and Definition Naturally occurring (undisturbed) soil and vegetation provide important stormwater fimctions including: water infiltration; nutrient, sediment, and pollutant adsorption; sediment and pollutant biofiltration; water interflow storage and transmission; and pollutant decomposition. These functions are largely lost when development strips away native soil and vegetation and replaces it with minimal topsoil and sod. Not only are these important stormwater f�mctions lost, but such landscapes themselves become pollution- generating pervious surfaces due to increased use of pesticides, fertilizers and other landscaping and household/industrial chemicals, the concentration of pet wastes, and pollutants that accompany roadside litter. Establishing soil quality and depth regains greater stormwater functions in the post development landscape, provides increased treatment of pollutants and sediments that result from development and habitation, and minimi es the need for some landscaping chemicals, thus reducing pollution through prevention. Applications and Limitations Establishing a minimum soil quality and depth is not the same as preservation of naturally occurring soil and vegetation. However, establishing a mmimum soil quality and depth will provide improved on - site management of stormwater flow and water quality. Soil organic matter can be attained through numerous materials such as compost, composted woody material, biosolids, and forest product residuals. It is important that the materials used to meet the soil quality and depth BNV be appropriate and beneficial to the plant cover to be established. Likewise, it is important that imported topsoils improve soil conditions and do not have an excessive percent of clay fines. Design Guidelines Soil retention. The duff layer and native topsoil should be retained in an undisturbed state to the maximum extent practicable. In any areas requiring grading remove and stockpile the duff layer and topsoil on site ' in a designated, controlled area, not adjacent to public resources and critical areas, to be reapplied to other portions of the site where feasible. Soil quality. All areas subject to clearing and grading that have not been covered by impervious surface, incorporated into a drainage facility or engineered as structural fill or slope shall, at project completion, demonstrate the following: 1. A topsoil layer with a minimum organic matter content of ten percent dry weight in planting beds, and 5% organic matter content in turf areas, and a pH from 6.0 to 8.0 or matching the pH of the February 2005 Volume V — Runoff Treatment BMPs 5-13 0 original undisturbed soil. The topsoil layer shall have a i i depth of eight inches except where tree roots limit the depth of incorporation of amendments needed to meet the criteria. Subsoils below the topsoil layer should be scarified at least 4 inches with some incorporation of the upper material to avoid stratified layers, where feasible. 2. Planting beds must be mulched with 2 inches of organic material 3. Quality of compost and other materials used to meet the organic content requirements: a. The organic content for "pre -approved" amendment rates can be met only using compost that meets the definition of "composted materials" in WAC. 173-350-220. This code is available online at: http://www.ecy.wa.gov/programs/sw:ffi/facifities/350.htmi The compost must also have an organic matter content of 35% to 65%, and a carbon to nitrogen ratio below 25: 1. The carbon to nitrogen ratio may be as high as 35:1 for plantings composed entirely of plants native to the Puget Sound Lowlands region. b. Calculated -amendment rates maybe met through use of composted materials as defined above; or other organic materials amended to meet the carbon to nitrogen ratio requirements, and meeting the contaminant standards of Grade A Compost. The resulting soil should be conducive to the type of vegetation to be established. Implementation Options: The soil quality design guidelines listed above can be met by using one of the methods listed below 1. Leave undisturbed native vegetation and soil, and protect from compaction during construction 2. Amend existing site topsoil or subsoil either at default "pre - approved" rates, or at custom calculated rates based on specifiers tests of the soil and amendment 3. Stockpile existing topsoil during grading, and replace it prior to planting. Stockpiled topsoil must also be amended if needed to meet the organic matter or depth requirements, either at a default "pre -approved" rate or at a custom calculated rate. 4. Import topsoil mix of sufficient organic content and depth to meet the requirements. 5-14 Volume V — Runoff Treatment BMPs February 2005 0 More than one method may be used on different portions of the same site. Soil that already meets the depth and organic matter quality standards, and is not compacted, does not need to be amended. PlanningIPermittinglInspectionIVerification Guidelines & Nocedures Local governments are encouraged to adopt guidelines and procedures similar to those recommended in Guidelines and Resources For Imiolementine Soil Oualitv and DeDth BMP T5.13 in WDOE Stormwater Manaaement Manual for Western Washinaton. This document is available at hgl2://www.soilsforsalmon.o Maintenance • Soil quality and depth should be established toward the end of construction and once established, should be protected from compaction, such as from large machinery use, and from. erosion. • Soil should be planted and mulched after installation. • Plant debris or its equivalent should be left on the soil surface to replenish organic matter. It should be possible to reduce use of irrigation, fertilizers, herbicides and pesticides. These activities should be adjusted where possible, rather than continuing to implement formerly established practices.

The project description, site conditions and our geotechnical conclusions and design recommendations are presented in the text of this report. Supporting data including detailed exploration logs and field exploration procedures, as well as results of laboratory testing are presented as appendices. Our geotechnical engineering scope of services for the project included a site reconnaissance, subsurface evaluation, laboratory testing and preparation of this report. The subsurface evaluation consisted of completing seven exploratory borings (designated B-1 through B-7) across the site and two shallow hand -excavated test pits (TP-1 and TP-2) beneath the existing building. The borings extended to depths of approximately 8% to 14 feet below ground surface (bgs) while the test pits were completed to a depth of 1 1/2feet. Figure 1, the Site and Exploration Plan, presents the approximate locations of our subsurface explorations completed for this project. Appendix A contains a description of our field procedures and the boring and test pit logs. Appendix B contains a description of the various laboratory testing procedures and the test results. SITE DESCRIPTION The project site is located at 21008 - 76" Avenue West in Edmonds, Washington. The project site is approximately 2.3 acres in size and is developed with the Prestige Care and Rehabilitation of Edmonds facility. The facility is currently vacant, but the building and surrounding pavement and landscaping are still intact. The site is relatively level overall. Plans for the existing structure indicate that the building was designed with conventional shallow foundations and a crawlspace. A few isolated spread footings west of the courtyard were apparently underpinned, apparently due to settlement. We understand that most of the stormwater runoff from the site is conveyed to the stormwater system in 76t" Avenue West and some of the roof runoff discharges to the ground. Non - building portions of the site are covered with asphalt pavement and landscaping. The site is bordered to the north by a multi -family residential development, to the south by commercial development, to the west by single-family and multi -family residential properties, and to the east by 76t" Avenue West and multi -family and commercial developments beyond. 0 Zipper Geo Associates, LLC Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 PROJECT UNDERSTANDING We understand that Prestige Care is planning to demolish the existing structure and construct a new building. The new 43,613 square -foot structure will include a 5,169 square -foot basement under the southeast comer of the building. Main and basement finish floor elevations are planned at 437.00 and 426.33 feet, respectively. The existing main parking area will be filled up to about 2.5 feet to create the parking area while the crawlspace of the existing building will be filled with about 1.5 to 2 feet of new structural fill. The new parking lot fill will be supported by approximately 2- to 4-foot tall rockeries. An approximate 7,000 square -foot, below -grade detention vault with 6 feet of storage is planned beneath the main parking area. SUBSURFACE EXPLORATIONS The subsurface evaluation consisted of seven borings (B-1 to B-7) completed across the site and two shallow hand -excavated test pits (TP-1 and TP-2) beneath the existing building. The borings were completed on July 11 and 12, 2013 while the test pits were completed on July 16, 2013. The approximate locations of the explorations are presented on Figure 1, the Site and Exploration Plan. The locations of the explorations were determined by taping from existing site features. SUBSURFACE CONDITIONS Published Geologic Mapping The Geologic map of the Edmonds East and part of the Edmonds West quadrangles, Washington (Miscellaneous Field Studies Map MF-1541, J.P. Minard, 1983) by the U.S. Geological Survey, indicates the site as being underlain by Vashon Till (Qvt). According to this publication, the Vashon Till is described as: "a non -sorted, mixture of clay, silt, sand, pebbles, cobbles, and boulders, all in variable amounts. It typically is hard lodgement till and often is referred to as hardpan. The "hardpan" is largely a result of compaction caused by the great weight of ice hundreds of meters thick. Internal drainage is greatly retarded by the unweathered till". Soil Conditions Soils were visually classified in the general accordance with the Unified Soil Classification System (USCS). After laboratory testing was completed on representative samples, soil descriptions were also developed using the USDA Soil Textural Classification System. Detailed descriptive logs presenting the subsurface conditions encountered, the associated USCS and USDA soil descriptions, and the procedures utilized in the subsurface exploration program are presented in Appendix A. Generalized descriptions of subsurface soil conditions observed in specific areas of the site are presented below. The vertical stratification and horizontal extent of the soil types appeared to vary between explorations. Variations in subsurface conditions exist between the exploration locations and the nature and extent of variations between the explorations may not become evident until Page 2 E Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 construction. Stratification boundaries on the boring logs represent the approximate depth of changes in soil types, although the transition between materials may have been gradual. If variations become apparent during construction, it may be necessary to reevaluate the recommendations of this report Borings B-1 and B-2 were completed in asphalt -paved areas. The pavement section in boring B-1 was approximately 11/2 inches of asphalt over 1 inch of crushed gravel base course. Boring B-2 encountered approximately 3 inches of asphalt over 3% inches of crushed gravel base course. Borings B-3 through B-7 were completed in grass -covered areas and generally encountered 6 to 8 inches of sod, root zone and organic -rich topsoil. Beneath the pavement sections and grass covered areas, soils interpreted as undocumented fill material or possible fill were encountered in borings B-11, B-4, B-5, B-6, and B-7. In general, the fill consisted of loose to dense silty sand with some gravel and sand with some silt and gravel that we interpreted to be of glacial till origin. The fill and possible fill vaded in thickness from approximately 41/2 to more than 7Y2 feet. Below the fill, grass areas, and pavement sections, native soils consisted of medium dense to very dense silty sand with some gravel and sand with some silt and gravel that we interpreted to be weathered and unweathered glacial till, respectively. Below the crawlspace, both hand -dug test pits disclosed dense glacial till. As part of a previous renovation/addition to the existing building in 1997/1998, we understand that four interior spread footings beneath the northern portion of the building were to have been over - excavated to a depth of 8 feet to remove "loose, organic subgrade material". We have not observed any information that would indicate if this was completed. The fill and possible fill encountered in borings B-5 and B-7 tend to corroborate the anecdotal information from 1997. Groundwater None of the borings encountered groundwater at the time of drilling. Groundwater levels, flow rates and soil moisture conditions should be expected to vary. Groundwater tends to perch within the weathered glacial till during the winter and spring periods of the year and during extended periods of precipitation. Fluctuations of the groundwater levels will likely occur due to seasonal variations in the amount of rainfall, runoff and other factors not evident at the time the explorations were performed. Therefore, groundwater levels during construction or at other times in the life of the structure may be higher than indicated on the logs. The probability of perched water should be considered when developing the design and construction plans for the project. The dense to very dense and silty nature of the native glacial till soils combine to provide low - permeability soils across the site. Therefore, groundwater should be expected to collect within backfilled excavations in the till. Page 3 0 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Summary of Laboratory Testing Laboratory testing was completed on select soil samples obtained from our borings. Laboratory testing included moisture content and grain size analysis. The results of moisture content testing are presented on the boring logs. Results of grain size testing are provided in Appendix B. Within the upper 10 feet of existing site grades in borings B-1 through B-7, moisture contents ranged from about 7 to 13 percent. Grain -size (sieve) tests indicate fines contents (silt and clay size particles) ranging from about 11 to 35 percent in representative near -surface samples. Only two of the eight samples tested had a fines content of less than 21 percent. CONCLUSIONS AND RECOMMENDATIONS General Considerations In our opinion, development as proposed appears feasible from a geotechnical engineering standpoint utilizing conventional, shallow, spread foundations. The fill and possible fill soils across the site, as well as loose soil reportedly beneath a portion of the existing building, vary in moisture content and relative compaction. This variability will likely become apparent during construction and the amount and extent of over -excavating of unsuitable soils will likely vary across the site. Wet weather prevails in the project vicinity for a significant portion of the year (generally mid -October through April). Site soils contain a significant fraction of fines and these soils will quickly become unstable, soft and unsuitable for reuse as structural fill during periods of seasonal wet weather. The following sections of this report present specific geotechnical recommendations for the project. Our recommendations are based on the observed soil conditions at specific exploration locations. Differing soil conditions than those observed in our borings may become evident during construction. The risk of such differing conditions is elevated on sites such as this site where previously placed fill is apparent. Our recommendations are further based on the assumption that earthwork for site grading, utilities, foundations, floor slabs, and pavements will be monitored by a qualified geotechnical engineer. Seismic Considerations Based on site location and soil conditions, the values provided below are recommended for seismic design. The values provided below are derived from the USGS US Seismic Design Maps Web Application based on USGS hazard data available in 2008.

These 2012 International Building Code Site Classification soils are characterized by average Standard Penetration (IBC) Test blowcounts greater than 50, average shear wave velocities between 1,200 and 2,500 feet per second, and average undrained shear strengths greater than 2,000 pounds per square foot.

The site soils are not considered to be prone to liquefaction due to their relative density. The potential for seismic related settlement is considered low. Based on our analyses, foundation bearing capacity failure is considered unlikely, and settlement of greater than 1 inch is considered to be low during a design -level earthquake provided the soils in the building pad are prepared as recommended in this report. Site Preparation Existing Structure Removal: We recommend that existing concrete on -grade slabs and foundations be removed pdor to grading. The resulting excavations should be backfilled with compacted structural fill or cement -treated soils. It would be possible to reuse the existing concrete for structural fill purposes, stabilization or bridging over areas of soft, unsatisfactory soil, or construction of haul roads and layclown areas, provided it is crushed to a suitable working size. Existing Utility Removal: We recommend that all underground utilities within the proposed building pad be completely removed if they are not going to be reused. Utility pipes outside the building envelope could be abandoned in place, provided they are fully grouted with controlled density fill (CDF) and the trench backfill is density tested to verify that it meets the compaction levels presented in the project specifications. Localized excavations made for removal of utilities or existing unsuitable trench backfill should be backfilled with structural fill as outlined in the following section of this report. Page 5 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Erosion Control Measures: Stripped surfaces and soil stockpiles are typically a source of runoff sediments. We recommend that silt fences, berms, and/or swales be installed around the downslope side of stripped areas and stockpiles in order to capture runoff water and sediment. If earthwork occurs during wet weather, we recommend that all stripped surfaces be covered with straw to reduce runoff erosion, whereas soil stockpiles should be protected with anchored plastic sheeting. Temporary Drainage: Stripping, excavation, grading, and subgrade preparation should be performed in a manner and sequence that will provide drainage at all times and provide proper control of erosion. The near surface site soils have a high fines (silt and clay) content and are therefore highly susceptible to disturbance and erosion when wet. The site should be graded to prevent water from ponding in construction areas and/or flowing into and/or over excavations. Exposed grades should be crowned, sloped, and smooth -drum rolled at the end of each day to facilitate drainage if inclement weather is forecasted. Accumulated water must be removed from subgrades and work areas immediately and prior to performing further work in the area. Equipment access may be limited and the amount of soil rendered unfit for use as structural fill may be greatly increased if drainage efforts are not accomplished in a timely manner. Successful drainage of saturated zones due to accumulations of surface water would be relatively slow due to the fines content of the surficial soils. Instead, aeration, chemical treatment, or removal and replacement would be more expeditious. Runoff from the existing asphalt paved areas should not be allowed to flow into excavation areas. We recommend that asphalt berms or sandbags be used to divert runoff around the excavation areas to a suitable discharge location if the existing pavement is left in place during construction to protect the subgrade. Clearinq and Stripping: We anticipate that clearing and stripping will be limited to existing landscape areas. Once surface runoff is controlled, areas of the site to be developed should be stripped of topsoil and vegetation. We estimate that topsoil stripping depths will average about 6 to 8 inches across the site where landscaping is present. Deeper areas of organic -rich soil, such as in the area of tree roots, may be encountered and should be removed to the recommended depth determined in the field by the owner's geotechnical representative. Determination will likely be made based on visual examination. Due to the proposed grading of the site, the existing asphalt pavement will need to be removed. Where possible, we recommend that the existing asphalt be left in place to temporarily protect the subgrade soils. Assessment of Reported Unsuitable Soils: As part of a previous renovation/addition to the existing building in 1997/1998, we understand that four interior spread footings beneath the northern portion of the building were to have been over -excavated to a depth of 8 feet to remove "loose, Page 6 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 organic subgrade material". We have not observed any information that would indicate if this was completed. Once the building is demolished and a backhoe can access the area, we recommend that test pit excavations be completed in this area to determine if additional unsuitable, organic - rich soils are present. If unsuitable soils are present we recommend they be over -excavated and replaced with compacted structural fill. Subgracle Preparation: Once site preparation is complete, all areas of exposed subgrade that do not require over -excavation and are at design subgrade elevation or subgrades that will receive new structural fill should be compacted to a firm and unyielding condition. Areas that may require over -excavation include the foundation and floor slab subgrades in the western portion of the existing building where loose soils were encountered. This will be discussed subsequently. Some moisture conditioning of site soils may be required to achieve a moisture content appropriate for compaction. During periods of extended wet weather, this could entail aeration and drying while during.the drier summer months, blending moisture into dry soils may be necessary. A suitable moisture content is generally within ±2 percent of the soil's optimum moisture content. Our laboratory testing indicates that, at the time our explorations were completed, moisture contents of the native glacial till and glacial till fill soils measured in the lab ranged from about 7 to 13 percent. We anticipate the optimum moisture content of the on -site soils would be on the order of 8 to 9 percent. Portions of the proposed building footprint could be underlain by undocumented fill material that was probably placed during the original site development. The relative density of the fill soils, as determined by the Standard Penetration Tests performed during the geotechnical evaluation, indicate the fill varies from loose to medium dense. Because of the variations in relative compaction, we recommend all undocumented fill soils be over -excavated and replaced with structural fill. After over -excavation, the exposed subgrade should be compacted to a minimum of 90 percent of the modified Proctor maximum dry density as determined by ASTM D 1557. The replacement backfill should be compacted to a minimum of 95 percent. In floor slab areas, if the fill is deemed to be suitable from a compositional standpoint and it is compacted to a minimum of 90 percent of the modified Proctor maximum dry density throughout, we recommend that the upper foot of the subgrade soil be compacted in place to a minimum of 95 percent of the modified Proctor maximum dry density. Earthwork should be completed during drier periods of the year when the soil moisture content can be controlled by aeration and drying. If earthwork or construction activities take place during extended periods of wet weather, or if the in situ moisture conditions are elevated above the optimum moisture content, the soils could become unstable or not be compactable. In the event the exposed subgrade becomes unstable, yielding, or unable to be compacted due to high moisture conditions, we recommend that the materials be removed to a sufficient depth in order to develop stable subgrade soils that can be compacted to the minimum recommended levels. Page 7 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 The severity of construction problems will be dependent, in part, on the precautions that are taken by the contractor to protect the subgrade soils. Once compacted, pavement and floor slab subgrades should be evaluated through density testing and proof rolling with a loaded dump truck or heavy rubber -tired construction equipment weighing at least 20 tons to assess the subgrade adequacy and to detect soft and/or yielding soils. In the event that the soils are not firm and unyielding, the upper 12 inches of subgrade should be scarified and moisture conditioned as necessary to obtain at least 95 percent of the maximum laboratory density (per ASTIVI D 1557). Those soils which are soft, yielding, or unable to be compacted to the specified criteria should be over -excavated and replaced with suitable material as recommended in the Structural Fill section of this report. Alternatively, over optimum soils could be treated with cement as a method to stabilize and strengthen soft, wet soils. To protect stable subgrades from construction traffic, either inside or outside the building footprint, we recommend using crushed rock or crushed recycled concrete. The thickness of the protective layer should be determined at the time of construction and. be based on the moisture condition of the soil and the amount of anticipated traffic. Freezing Conditions: If earthwork takes place during freezing conditions, all exposed subgrades should be allowed to thaw and then be compacted prior to placing subsequent lifts of structural fill. Alternatively, the frozen material could be stripped from the subgrade to expose unfrozen soil prior to placing subsequent lifts of fill or foundation components. The frozen soil should not be reused as structural fill until allowed to thaw and adjusted to the proper moisture content, which may not be possible during winter months. Structural Fill Materials and Placement Structural fill includes any material placed below foundations, floor slabs and pavement sections, within utility trenches, and behind retaining walls. Prior to the placement of structural fill, all surfaces to receive fill should be prepared as previously recommended in the Site Preparation section of this report. Laboratory Testing: Representative samples of on -site and imported soils to be used as structural fill should be submitted for laboratory testing at least 4 days in advance of its intended use in order to complete the necessary Proctor tests. Reuse of Site Soils as Structural Fill: It is our opinion that the non -organic native and fill soils encountered on the site are suitable for reuse as general structural fill from a compositional standpoint provided they are placed and compacted in accordance with the recommendations presented in this report. Some of the site soils may be wet of optimum at the time of construction and will require moisture conditioning (drying) prior to use as structural fill. The reuse of site soils as structural fill during wet weather will be difficult or impossible due to their moisture sensitivity. Page 8 0 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Reusing over -optimum soils during periods of wetter, cooler weather would likely require cement stabilization. We recommend that site soils used as structural fill have less than 4 percent organics by weight and have no woody debris greater than 1/2 inch in diameter. We recommend that all pieces of organic material greater than Y2inch in diameter be picked out of the fill before it is compacted. Organic -rich soil derived from earthwork activities should be used in landscape areas or be wasted from the site. Imported Structural Fill: Imported structural fill may be required due to weather, wet soil conditions, or other reasons. The appropriate type of imported structural fill will depend on the prevailing weather conditions. During extended periods of dry weather when soil moisture can be controlled, we recommend imported fill meet the requirements of Common Borrow as specified in Section 9-03.14(3) of the 2012 Washington State Department of Transportation, Standard Specifications for Road, Bridge, and Municipal Construction (WSDOT Standard Specifications). The on -site soils would be classified as Common Borrow. During wet weather, higher -quality (lower fines content) structural fill might be required, as Common Borrow may contain sufficient fines to be moisture sensitive. During wet weather we recommend that imported structural fill meet the requirements of Gravel Borrow as specified in Section 9-03.14(l) of the WSDOT Standard Specifications. Retaininq Wall Backfill: Retaining walls should include a drainage fill zone extending at least 18 inches back from the back face of wall for the entire wall height. The drainage fill should meet the requirements of Gravel Backfill for Walls as specified in Section 9-03.12(2) of the WSDOT Standard Specifications. Pavement Sub -grades: Any structural fill used within the upper one foot below pavement sections should have a minimum California Bearing Ratio (CBR) of 20 at a compaction level of 95 percent of the modified Proctor maximum dry density. A CBR value of 20 is representative of the soils encountered at the site and has been assumed to develop our pavement section recommendations. Moisture Content: The suitability of soil for use as structural fill will depend on the prevailing weather at the time of construction, the in situ moisture content of the soil, and the fines content (that portion passing the US No. 200 sieve) of the soil. As the amount of fines increases, the soil becomes increasingly sensitive to small changes in moisture content. Soils containing more than about 5 percent fines (such as the on -site soils) cannot be consistently compacted to the appropriate levels when the moisture content is more than approximately 2 percent above or below the optimum moisture content (per ASTM D 1557). Optimum moisture content is that moisture content which results in the greatest compacted dry density with a specified compactive effort. Page 9 0 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Fill Placement: Structural fill should be placed in horizontal lifts not exceeding 10 inches in loose thickness. Each lift of fill should be compacted using compaction equipment suitable for the soil type and lift thickness. Each lift of fill should be compacted to the minimum levels recommended below based on the maximum laboratory dry density as determined by the ASTM D 1557 Modified Proctor Compaction Test. Moisture content of fill at the time of placement should be within plus or minus 2 percent of optimum moisture content for compaction as determined by the ASTM D1557 test method. Compaction Criteria: Our recommendations for soil compaction are summarized in the following table. Structural fill for roadways and utility trenches in municipal rights -of -way should be placed and compacted in accordance with the City of Edmonds codes and standards. We recommend that a geotechnical engineer be present during grading so that an adequate number of density tests may be conducted as structural fill placement occurs. In this way, the adequacy of the earthwork may be evaluated as it proceeds. RECOMMENDED SOIL COMPACTION LEVELS Location Minimum Percent Compaction* All fill below building floor slabs and foundations 95 Upper 2 feet of fill below pavements 95 Pavement fill below two feet 92 Retaining wall backfill less than 3 feet from wall 90 Retaining wall backfill more than 3 feet from wall 92 Upper two feet of utility trench backfill 95 utility t nches below two feet 92 Landscape Areas 90 AS TM D 1557 Modified Proctor Maximum Dry Density Utility Trenching and Backfilling We recommend that utility trenching conform to all applicable federal, state, and local regulations, such as OSHA and WISHA, for open excavations. Trench excavation safety guidelines are presented in WAC Chapter 296-155 and WISHA RCW Chapter 49.17. Trench Dewatering: Perched groundwater zones may be encountered in basement, trench and stormwater vault excavations during the winter and spring months but could likely be controlled with sump pits and pumps in the excavations. The depth to and flow rate of perched groundwater will fluctuate throughout the year. At times, seepage could be heavy enough to require flattening the sidewalls of excavations to reduce the risk of caving. Some caving of utility trench sidewalls should be anticipated in association with groundwater seepage. We recommend that any excavations within groundwater seepage zones be undertaken only when suitable clewatering Page 10 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 equipment and temporary excavation shoring are available, or where space is available to flatten the sidewalls. If greater clewatering efforts (such as wells) become necessary, it should be designed and maintained by the contractor. The appropriate type of dewatering system should be determined by the contractor based on the conditions encountered. Utility Subgrade Preparation: We recommend that all utility subgrades be firm and unyielding and free of all soils that are loose, disturbed, or pumping. Such soils should be removed and replaced, if necessary. All structural fill used to replace over -excavated soils should be compacted as recommended in the Structural Fill section of this report. If utility foundation soils are soft, we recommend that they be over -excavated 12 inches and replaced with crushed rock. Structures such as manholes and catch basins which extend into soft soils should be underlain by at least 12 inches of crushed gravel fill compacted to at least 90 percent of the modified Proctor maximum dry density. This granular material could consist of crushed rock, quarry spalls, permeable ballast, or coarse crushed concrete. It may be necessary to place a geotextile fabric over the native subgrade soils if they are too soft to provide a separation between the bedding and subgrade soils. Beddinq and Initial Backfill: We recommend that a minimum of 4 inches of bedding matedal be placed above and below all utilities or in general accordance with the utility manufacturer's recommendations and local ordinances. We recommend that pipe bedding consist of Gravel Backfill for Pipe Zone Bedding as specified in Section 9-03.12(3) of the WSDOT Standard Specifications. All trenches should be wide enough to allow for compaction around the haunches of the pipe, or material such as pea gravel should be used below the spring line of the pipes to eliminate the need for mechanical compaction in this portion of the trenches. If water is encountered in the excavations, it should be removed prior to fill placement. Trench Backfill: Materials, placement and compaction of utility trench backfill should be in accordance with the recommendations presented in the Structural Fill section of this report. In our opinion, the initial lift thickness should not exceed one foot unless recommended by the manufacturer to protect utilities from damage by compacting equipment. Light, hand operated compaction equipment may be utilized directly above utilities if damage resulting from heavier compaction equipment is of concern. Temporary and Permanent Slopes Temporary excavation slope stability is a function of many factors, including: • The presence and abundance of groundwater; • The type and density of the various soil strata; • The depth of cut; • Surcharge loadings adjacent to the excavation; and 0 The length of time the excavation remains open. Page 11 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 As the cut is deepened, or as the length of time an excavation is open, the likelihood of bank failure increases; therefore, maintenance of safe slopes and worker safety should remain the responsibility of the contractor, who is present at the site, able to observe changes in the soil conditions, and monitor the performance of the excavation. It is exceedingly difficult under the variable circumstances to pre -establish a safe and "maintenance -free" temporary cut slope angle. Therefore, it should be the responsibility of the contractor to maintain safe temporary slope configurations since the contractor is continuously at the job site, able to observe the nature and condition of the cut slopes, and able to monitor the subsurface materials and groundwater conditions encountered. We recommend the contractor make a determination of excavation side slopes based on classification of soils encountered at the time of excavation in accordance with the guidelines presented in Section 296-155, Part N of the Washington State Administrative Code and applicable construction industry specific guidelines. Based on the conditions encountered in the borings, it appears the soils would be classified as Type C. Temporary cuts may need to be constructed at flatter angles based upon the soil moisture and groundwater conditions at the time of construction. Adjustments to the slope angles should be determined by the contractor at that time. Unsupported vertical slopes,or cuts deeper than 4 feet are not recommended if worker access is necessary. The cuts should be adequately sloped, shored, or supported to prevent injury to personnel from local sloughing and spalling. We recommend that all permanent cut or fill slopes constructed in native soils be designed at a 2Y2H:lV (Horizontal:Vertical) inclination or flatter. All permanent cut and fill slopes should be adequately protected from erosion both temporarily and permanently. Stormwater Detention Vault A relatively large detention vault is planned beneath the main parking lot. For planning purposes, we recommend using 1H:1V temporary side slope inclinations to determine the temporary excavation limits and evaluate that such an excavation would not interfere with existing utilities or other features that cannot be disturbed. If interference with existing utilities and structures must be avoided, other options are available that could allow for steeper (up to vertical) slopes. No soil borings were completed in the area of the proposed vault. However, based on the soil conditions encountered in the borings advanced in other areas, it appears the vault would be supported on dense to very dense native soils. If shallow footings are used, we recommend using a maximum allowable bearing capacity of 3,500 psf. We recommend the base slab be supported on a minimum of 6 inches of crushed gravel conforming to WSDOT Standard Specification 9- 03.9(3) for Crushed Gravel Base Course or Crushed Gravel Top Course. We recommend that drainage be provided around the vault since the surrounding soils are relatively impermeable and groundwater seepage will collect in the backfilled excavation. We Page 12 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 recommend that a footing drain be installed as deep as possible, preferably at the base of the structure, to prevent the build-up of hydrostatic pressure. If the drain pipe cannot be installed at the base of the structure due to elevations of nearby tie-in drainage structures, we recommend the vault be designed for hydrostatic pressure below the elevation of the drain pipe. We recommend the walls be backfilled with a minimum of 18 inches of free -draining material that communicates with the drain pipe. The drainage aggregate should consist of material meeting the requirements of WSDOT 9-03.12(2) Gravel Backfill for Walls. Drain pipe perforations should be protected using a non -woven filter fabric such as Mirafi 140N. For on -site soils placed on top of a vault as structural fill, as well as the asphalt base course and asphalt surfacing, we recommend using a moist unit weight of 140 pounds per cubic foot. Preliminary Stormwater Infiltration Suitability We understand the stormwater management system may include infiltration and/or detention structures. Preliminary estimated infiltration rates for potential stormwater management areas were determined in general accordance with Appendix C of the Edmonds Stormwater Code Supplement. ASTM gradation testing was completed on eight samples of the receptor soils obtained from our borings. We used the test results to determine the textural classification in accordance with the methodology presented in the USDA Soil Survey Manual (11993). Our testing indicates the receptor soils may be somewhat Variable across the site. The following table presents our findings and the associated long-term estimated infiltration rates. SOIL DESCRIPTIONS AND ASSOCIATED PUBLISHED LONG-TERM INFILTRATION RATES Boring Number Sample Number and Depth USDA Textural Classification Estimated Long -Term Infiltration Rate (in./hr.) B-1 S-2 @ 5-6Y2ft. Sandy Loam 0.25 B-1 S-3 @ 7Y2-9 ft. Sandy Loam 0.25 B-2 S-1 @ 21/2-4 ft. Loamy Sand 0.5 B-4 S-1 @ 2Y2-4 ft. Sandy Loam 0.25 B-4 S-2 @ 5-61/2ft. Loamy Sand 0.5 B-5 S-1 @ 2Y2-4 ft. Sand 2 B-5 S-2 @ 5-6Y2ft. Loamy Sand 0.5 B-5 S-3 @ 7Y,-9 ft. Loamy Sand 0.5 The long-term infiltration rates presented in the City's Stormwater Code Supplement are based on the Washington State Department of Ecology (WSDOE) Stormwater Management Manual for Western Washington (2005). The published infiltration rates are based on the assumption that the receptor soils are homogeneous and normally consolidated. The on -site soils originated as glacial till which have been consolidated by thousands of feet of ice and are over -consolidated as a result. The soil density is not represented in the gradation tests and in our opinion greatly Page 13 0 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 ' reduces the in situ infiltration rate. The actual infiltration rates should be considered negligible without verifying the actual infiltration rates through field testing. Based on the conditions disclosed by the explorations, laboratory testing results, and experience with other projects of a similar nature, it is our opinion that conventional storm water infiltration is not feasible at the site. In the event that rain gardens are constructed for treatment purposes, we recommend that overflows be installed that will allow excess water to be piped to the stormwater system. Shallow Building Foundations In our opinion, shallow spread and continuous footings are suitable for support of the proposed structure, from a geotechnical engineering standpoint. However the wall backfill for the basement should not be relied upon for support of main floor foundations that tie into the basement walls because the wall backfill should be free -draining and could shift or settle slightly after placement.. We recommend that foundations in the wall backfill zone step down as they approach the wall backfill so they remain supported by native soils. Alternatively, the shallow foundation should be designed as a grade beam to span over the width of the wall backfill. Bearing Sub. grade: The loose soils encountered in borings B-1 and B-5 could extend under some of the proposed footings in those respective areas. There also could be other areas of loose bearing soils that may not become evident until construction either because they are presently under the existing building or they were not encountered in our borings. ZGA has located the test pit logs for the addition and it appears that medium dense fill and native soils extended to depths of 3 to 7 feet below former site grades. The undocumented fill soils reported should not be considered suitable for support of the new foundations. We recommend that the foundations be supported on properly prepared structural fill placed above undisturbed native soils or directly on the undisturbed native soils. Soils that are loose to medium dense should be over -excavated to expose dense native soils. Where foundation subgrade soils are over -excavated and backfilled with structural fill, the excavation should extend laterally away from each side of the footing a distance of 8 inches for each foot the excavation extends vertically below the foundation. If lean mix is used to backfill excavations below footings, the excavation only needs to extend 6 inches beyond the limits of the foundation regardless of the depth of over -excavation. The resulting excavation should be backfilled with lean mix having a minimum 28-day compressive strength of 100 psi. The foundation subgrade should be observed and tested by a representative of ZGA prior to placement of any structural fill, formwork or reinforcing steel. Page 14 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Allowable Bearing Pressure: Based on our understanding of grading for the building, we anticipate the foundation bearing soils could vary from medium dense to very dense. In order to limit differential settlements to tolerable limits, we recommend using an allowable bearing capacity that is appropriate for the medium dense soils. Continuous and column footings bearing on undisturbed medium dense to very dense native soil and structural fill compacted to a minimum of 95 percent of the modified Proctor maximum dry density should be designed for a maximum allowable, net, bearing capacity of 2,500 psf. A one-third increase of the bearing pressure may be used for short -tern dynamic loads such as wind and seismic forces. Shallow Foundation Depth and Width: For frost protection, the bottom of all exterior footings should bear at least 18 inches below the lowest adjacent outside grade, whereas the bottoms of interior footings should bear at least 12 inches below the surrounding slab surface level. We recommend that all continuous wall and isolated column footings be at least 12 and 24 inches wide, respectively. Lateral Resistance: We recommend using allowable base friction and passive earth values of 0.33 and 250 pcf equivalent fluid pressure, respectively. We recommend that passive resistance be neglected in the upper 18 inches of embedment. Estimated Settlement: Assuming the foundation subgrade soils are prepared in accordance with recommendations presented herein, we estimate that total and differential settlements will be less than 1 inch and % inch, respectively. Backfilled Permanent Retaining Walls Lateral Earth Pressures: The lateral soil pressures acting on backfilled retaining walls will depend on the nature and density of the soil behind the wall, and the ability of the wall to yield in response to the earth loads. Yielding walls (i.e. walls that are free to translate or rotate) that are able to displace laterally at least 0.001 H, where H is the height of the wall, may be designed for active earth pressures. Non -yielding walls (i.e. walls that are not free to translate or rotate) should be designed for at -rest earth pressures. Non -yielding walls include walls that are braced to another wall or structure, and wall corners. Assuming that walls are backfilled and drained as described in the following paragraphs, we recommend that yielding walls supporting horizontal backfill be designed using an equivalent fluid density of 35 pcf (active earth pressure). Non -yielding walls should be designed using an equivalent fluid density of 50 pcf (at -rest earth pressure). Surcharge pressures due to sloping backfill, adjacent footings, vehicles, construction equipment, etc. must be added to these lateral earth pressure values. For traffic loads, we recommend using an equivalent two foot soil surcharge of about 250 psf. For loading docks, point, continuous or evenly distributed loads above the dock will result in horizontal pressure on the wall. The Page 15 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 appropriate loading conditions should be incorporated into the loading dock wall design, or we can provide surcharge criteria for loading conditions behind the loading dock wall, if requested. For yielding walls with level backfill conditions, we recommend that a uniformly distributed seismic pressure of 4.5H psf for the active case and 9.OH psf for the at -rest case, where H is the height of the wall, be applied to the walls. The above equivalent fluid pressures are based on the assumption of no buildup of hydrostatic pressure behind the wall. If groundwater is allowed to saturate the backfill soils, hydrostatic pressures will act against a retaining wall; however, if the recommended drainage system is included with each retaining wall, we do not expect that hydrostatic pressures will develop. Drainage: Adequate drainage measures must be installed to collect and direct subsurface water away from subgrade walls. All backfilled walls should include a drainage aggregate zone extending a minimum of 18 inches from the back of wall forthe full height of the wall. The drainage aggregate should consist of material meeting the requirements of WSDOT Standard Specification 9-03.12(2), Gravel Backfill for Walls. A minimum 4-inch diameter, perforated PVC drain pipe should be provided at the base of the backfilled wall footings to collect and direct subsurface water to an appropriate discharge point. Drain pipe perforations should be protected using a non -woven filter fabric such as Mirafi 140N. Footing drains should be installed below the cold joints between backfilled walls and the underlying foundations. If this is not possible, we recommend designing a waterstop, into the cold joint to prevent the migration of water beneath the interior floor slab. An extra level of water -proofing could be applied directly to the backfilled wall in the form of a drainage composite. Generally, drainage composites are installed from the top of the backfill to the top of the footing. Free -draining aggregate is placed over the top of the footing and down the side of the footing so that the collected water can flow to the footing drain. Products such as Miradrain by Tencate and J-Drain 400 by JDR Enterprises would be suitable for this application. We can provide names of other products upon request. Wall drainage systems should be independent of other drainage systems such as roof drains. On -Grade Concrete Slabs Sub -grade Preparation: All fill placed beneath floor slabs should be compacted to a minimum of 95 percent of the modified Proctor maximum dry density. It is possible that some of the existing fill within the footprint of the proposed building will not meet this recommended level of compaction. As such, the actual amount of over -excavation and replacement will be dependent on the horizontal and vertical extent of existing fill and its relative compaction. Existing fill material that is not compacted to a minimum of 90 percent of the modified Proctor maximum dry density should be reworked and compacted in order to achieve the minimum recommended compaction levels. Page 16 0 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Slab Base: To provide a uniform slab bearing surface, we recommend the on -grade slabs be underlain by a 4-inch thick layer of compacted crushed gravel meeting the requirements of Crushed Surfacing Top Course as specified in Section 9-03.9(3) of the WSDOT Standard Specifications. We further recommend that the fines content (that portion passing the US No. 200 sieve) of the crushed gravel be limited to a maximum of 7.5 percent. Vapor Barrier: A vapor barrier is not necessary beneath slab on grade floors unless moisture sensitive floor coverings and/or adhesives are used. If a vapor barrier is used, we recommend using a 10-mil puncture -resistant product that is classified as a Class A vapor retarder in accordance with ASTM E1745. Puncturing the vapor barrier should be avoided; construction traffic should not be allowed to drive over any vapor barrier material. We recommend the barrier have taped overlapping joints and where pipes and other objects penetrate the barrier, we also recommend taping these. When conditions warrant the use of a vapor retarder, the slab designer and slab contractor should refer to ACI 302 and ACI 360 for procedures and cautions regarding the use and placement of a vapor retarder/barrier. Sub -grade Modulus: For design of on -grade concrete slabs supported on compacted fill soils, we recommend a vertical modulus of subgrade reaction of 225 pounds per cubic inch (pci) be used. This value is suitable if the on -site soils are reused as structural fill beneath the slab. Drainage Considerations Surface Drainage: Final site grades should be sloped to carry surface water away from buildings and other drainage -sensitive areas. Additionally, site grades should be designed such that concentrated runoff on softscape surfaces is avoided. Subsurface Perimeter Draina-ge: We recommend a permanent footing drain system be installed around the building perimeter. Drains for footings and backfilled walls should consist of an aggregate drainage zone (as recommended in the Structural Fill section) and a drain pipe. Drain pipes should consist of a minimum 4-inch diameter, rigid -wall, perforated drainpipe installed at the base of the wall footing. The pipe should be wrapped in a filter sock (such as Mirafi 140N) to prevent sand and gravel from washing into the perforations. To prevent water backup in the pipes, the drainpipes should be connected at regular intervals to a tightline system leading to a suitable discharge. Cleanouts should be provided for future maintenance. The footing drain system must be separate from the roof drain system. Page 17 0 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Rockeries Based on our review of the current site plan, rockeries are planned around the east, west and south sides of the main parking lot. The proposed rockeries will be situated along the property boundary and will support fill soils. The rockeries; will vary in exposed height from about 1 Y2to 3Y2 feet will support structural fill parked automobile surcharges. In general, the purpose of rockeries is to provide erosion protection for stable cuts made in competent native soils. Rockeries can be used to support limited heights of fills. However, the fill must be over -built and then cut back in order to provide a competent, compacted core which the rockery will support. In this case, over -building the fill would result in the fill encroaching on the adjacent property. If a temporary construction easement can be obtained, over -building the fill would be feasible. Otherwise, we recommend the fill be reinforced with a woven geotextile such as Mirafi HIP 370 or equivalent. A typical detail of a reinforced fill rockery is provided on the attached Figure 2, Reinforced Fill Rockery. Pavements Asphalt Pavements Pavement Life and Maintenance: It should be realized that asphaltic pavements are not maintenance -free. The following pavement sections represent our. minimum recommendations for an average level of performance during a 20-year design life; therefore, an average level of maintenance will likely be required. Thicker asphalt, base, and subbase courses would offer better long-term performance, but would cost more initially. Conversely, thinner courses would be more susceptible to "alligator" cracking and other failure modes. As such, pavement design can be considered a compromise between a high initial cost and low maintenance costs versus a low initial cost and higher maintenance costs. Soil Design Values: The native subgrade soils are anticipated to consist of a varying mixture of silt, sand and gravel. Based on the typical values provided by compacted glacial till fill, we have estimated a California Bearing Ratio (CBR) value of 20 percent for this project. Traffic Desiqn Values: No traffic loading was provided for this project. We have assumed low traffic volumes of less than 50,000 ESALs over a 20-year design life for light- and heavy-duty pavements. If traffic routes are expected across the site that could increase the estimated traffic count, ZGA should be notified so that we can re -analyze the pavement sections. Recommended Pavement Sections- For light duty pavements (parking lot areas), we recommend 2Y2 inches of asphalt concrete over 4 inches of crushed rock base course. For heavy duty pavements (main access roads, truck delivery routes, etc.), we recommend 3 inches of asphalt concrete over 4 inches of crushed rock base course. Page 18 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 Materials and Construction: We recommend the following regarding asphalt pavement materials and pavement construction. Subgrade Preparation: The upper 12 inches of pavement subgrade should be prepared in accordance with the recommendations presented in the Subgrade Preparation section of this report. Asphalt Concrete: We recommend that the asphalt concrete conform to Section 9-02.1(4) for PG 58-22 or PG 64-22 Performance Graded Asphalt Binder as presented in the 2012 WSDOT Standard Specifications. We also recommend that the gradation of the asphalt aggregate conform to the aggregate gradation control points for Y2-inch mixes as presented in Section 9-03.8(6), HMA Proportions of Materials. We recommend that the mix design of the proposed asphalt be based on gyratory compaction levels using 50 or 75 gyrations (not 100 or more). Base Course: We recommend that the crushed aggregate base course conform to Section 9-03.9(3), Crushed Surfacing Base Course, of the WSDOT Standard Specifications. Compaction: All base material should be compacted to at least 95 percent of the maximum dry density determined in accordance with ASTM D 1557. We recommend that asphalt be compacted to a minimum of 92 percent and a maximum of 96 percent of the Rice (theoretical maximum) density. Concrete Pavements Concrete Properties and Thickness: Concrete pavement design recommendations are based on an assumed modulus of rupture of 600 psi and a minimum compressive strength of 4,000 psi for the concrete. For light -duty pavements, we recommend 5 inches of concrete over 3 inches of crushed aggregate base. For heavy duty pavements, we recommend 5y2inches of concrete over 3 inches of crushed aggregate base. CLOSURE The analysis and recommendations presented in this report are based, in part, on the explorations completed for this study. The number, location, and depth of the explorations were completed within the constraints of budget and site access so as to yield the information to formulate our recommendations. Project plans were in the preliminary stage at the time this report was prepared. We therefore recommend we be provided an opportunity to review the final plans and specifications when they become available in order to assess that the recommendations and design considerations presented in this report have been properly interpreted and implemented into the project design. Page 19 0 0 Zipper Geo Associates, LLQ Proposed Prestige Care Facility Reconstruction Edmonds, WA Project No. 1151.01 April 22, 2014 The performance of earthwork, structural fill, foundations, and pavements depend greatly on proper site preparation and construction procedures. We recommend that Zipper Geo Associates, LLC be retained to provide geotechnical engineering services during the earthwork - related construction phases of the project. If variations in subsurface conditions are observed at that time, a qualified geotechnical engineer could provide additional geotechnical recommendations to the contractor and design team in a timely manner as the project construction progresses.

STRUCTURAL FILL PLACED AND COMPACTED IN ACCORDANCE WITH GEOTECHNICAL REPORT 0 APPENDIX A FIELD EXPLORATION PROCEDURES AND LOGS 0 FIELD EXPLORATION PROCEDURES Our field exploration program for this project included completion of seven exploratory borings (designated B-1 through B-7) across the site and two shallow hand -excavated test pits (TP-1 and TP-2) beneath the existing building. The borings extended to depths of approximately 8% to 14 feet below ground surface (bgs) while the test pits were completed to a depth of 11/2 feet. The approximate locations of the borings are presented on Figure 1, the Site and Exploration Plan. Exploration locations were determined in the field by measuring distances from existing site features shown on a survey provided by the project civil engineer. As such, the exploration locations should be considered accurate to the degree implied by the measurement method. The following sections describe our procedures associated with the explorations. Descriptive logs of the explorations are enclosed in this appendix. Soil Borings Borings were advanced with a hollow -stem auger, using a small track mounted drill rig and a portable Acker rig operated by an independent drilling company (Geologic Drill) working under subcontract to our firm. A geotechnical engineer from ZGA continuously observed the borings, logged the subsurface conditions encountered, and obtained representative soil samples. All samples were stored in moisture -tight containers and transported to our laboratory for further visual classification and testing. As part of the testing program, all of the samples were visually examined in the laboratory and classified in accordance with the attached General Notes. Throughout the drilling operation, soil samples were obtained at 2.5- to 5-foot intervals by means of the Standard Penetration Test (ASTM: D 1586). This testing and sampling procedure consists of driving a standard 2-inch outside diameter steel split spoon sampler 18 inches into the soil with a 140-pound hammer free falling 30 inches. The number of blows required to drive the sampler through each 6-inch interval is recorded, and the total number of blows struck during the final 12 inches is recorded as the Standard Penetration Resistance, or "blow count" (N value). If a total of 50 blows are struck within any 6-inch interval, the driving is stopped and the blow count is recorded as 50 blows for the actual penetration distance. The resulting Standard Penetration Resistance values indicate the relative density of granular soils and the relative consistency of cohesive soils. The enclosed boring logs describe the vertical sequence of soils and materials encountered in each boring, based primarily upon our field classifications and supported by our subsequent laboratory examination and testing. Where a soil contact was observed to be gradational, our logs indicate the average contact depth. Where a soil type changed between sample intervals, we inferred the contact depth. Our logs also graphically indicate the blow count, sample type, sample number, and approximate depth of each soil sample obtained from the boring, as well as any laboratory tests performed on these soil samples. If any groundwater was encountered in a borehole, the approximate groundwater depth, and date of observation, is depicted on the log. Groundwater depth estimates are typically based on the moisture content of soil samples, the wetted portion of the drilling rods, the water level measured in the borehole after the auger has been extracted, or through the use of an observation well. The boring logs presented in this appendix are based upon the drilling action, observation of the samples secured, laboratory test results, and field logs. The various types of soils are indicated as well as the depth where the soils or characteristics of the soils changed. It should be noted that these changes may have been gradual, and if the changes occurred between sample intervals, they were inferred. Test Pits The test pits were excavated in the crawlspace of the existing building using hand tools. 0 11 a Boring Location: See Figure 1, Site and Exploration Plan Drilling Company: Geologic Drill Bore Hole Dia.: 6" Top Elevation: - Drilling Method: Hollow Stem Auger Hammer Type: Cat Head B-1 Date Drilled: 7/11/2013 Drill Rig: Track Lqgqed b - TAJ y. ig :S CL 4) .0- SOIL DESCRIPTION w E a, M _j (D z CL > 02 8 a :c (D E ca 'a r_ 2 0 — PENETRATION RESISTANCE (blowstfoot) A Standard Penetration Test 0 A Hammer weight and Drop: 0 — 0 20 40 do Q The stratification lines represent the approximate boundaries between soil types.

Descriptions of the types of tests performed are given below. Visual Classification Samples recovered from the exploration locations were visually classified in the field during the exploration program. Representative portions of the samples were carefully packaged in moisture tight containers and transported to our laboratory where the field classifications were verified or modified as required. Visual classification was generally done in accordance with ASTM D 2488. Visual soil classification includes evaluation of color, relative moisture content, soil type based upon grain size, and accessory soil types included in the sample. Soil classifications are presented on the exploration logs in Appendix A. Moisture Content Determinations Moisture content determinations were performed on representative samples obtained from the explorations in order to aid in identification and correlation of soil types. The determinations were made in general accordance with the test procedures described in ASTM D 2216. Moisture contents are presented on the exploration logs in Appendix A. Grain Size Analysis A grain size analysis indicates the range in diameter of soil particles included in a particular sample. Grain size analyses were performed on representative samples in general accordance with ASTM D 2487. The results of the grain size determinations for the samples were used in classification of the soils, and are presented in this appendix. 0 E E GRAIN SIZE ANALYSIS Test Results Summary ASTM D 422 100 A 80 w 70 60 w z 50 z w 0 W 40 w CL 30 20 10 0 1000.000 100.000 10.000 1.000 0.100 0.010 0.001 PARTICLE SIZE IN MILLIMETERS BOULDERS COBBLES Coarse Fine Coa rse I Medium Fine Silt y Cla L�::] GRAVEL SAND FINE GRAINED Comments: Exploratio Sample Depth (feet) Moisture Fines (%) Description B-1 S-2 5 - 6Y2 14.9 32.9 Silty gravelly SAND ProjectNo.: 1151.01 PROJECT NAME: Zipper Geo Associates, LLC DATE OF TESTING: 7/13/2013 Geotechnical and Environmental Consultants Prestige Care 0 GMAIN SIZE ANALYSIS Test Results Summary ASTM D 422 100 �*It 80 W 70 Cal W 60 UJ z 50 z W L) W 40 LU IL 30 20 10 0 1000.000 100.000 10.000 1.000 0.100 0.010 0.001 PARTICLE SIZE IN MILLIMETERS BOULDERS COBBLES Coarse Fine Coarse I Medium Fine silt Clay GRAVEL SAND FINE GRAINED Comments: Exploratio Sample Depth (feet) Moisture Fines (%) Description B-1 S-3 7Y2-9 11.9 33.5 Silty SAND with some gravel I Project No.: 1151.01 PROJECT NAME: Zipper Geo Associates, LLC DATE OF TESTING: 7/13/2013 Geotechnical and Environmental Cong-iltants Prestige Care 0 0 GIRAIN SIZE ANALYSIS Test Results Summary ASTM D 422 100 Kc 80 W 70 W 60 W z 50 z W 0 W 40 W (L 30 20 10 0 1000.000 100.000 10.000 1.000 0.100 0.010 0.001 PARTICLE SIZE IN MILLIMETERS BOULDERS COBBLES C arse Fine Coarse I Medium Fine ilt Sift Clay GRAVEL SAND FINE GRAINED Comments: Exploratio Sample Depth (feet) Moisture Fines(%) Description B-4 S-2 5 - 6Y2 9.6 23.3 Silty SAND with some gravel ProjectNo.: 1151.01 PROJECT NAME: Zipper Geo Associates, LLC DATE OF TESTING: 7/13/2013 Geotechnical and Environmental Consultants Prestige Care E 0 GIRAIN SIZE ANALYSIS Test Results Summary ASTM D 422 100 M8 80 70 60 LLJ z 50 z w L) W 40 LU a. 30 20 10 0 100U.Uuu 100.000 10.000 1.000 0.100 0.010 0.001 PARTICLE SIZE IN MILLIMETERS BOULDERS COBBLES Coarse I Fine —[SAND �'edium M Fine Silt Cla�: GRAVEL FINE GRAINED Comments: Exploration Sample Depth (f=eet) =Moisture(%) Fines(%) Description B-2 S-1 2Y2-4 8.4 I 21.3 Silty gravelly SAND Zipper Geo Associates, LLC Project No.: 1151.01 PROJECT NAME: Geotechnical and Environmental Consultants DATE OF TESTING: 7/13/2013 Prestige Care -, I E 0 GRAIN SIZE ANALYSIS Test Results Summary ASTM D 422 100 KE 80 w 70 CID W 60 w z 50 z LU L) W 40 Lu CL 30 20 10 0 1000.000 100.000 10.000 1.000 0.100 0.010 0.001 PARTICLE SIZE IN MILLIMETERS BOULDERS COBBLES Coarse Fine edium Fine silt GRAVEL SAND FINE GRAINED Comments: Exploratio Sample Depth (feet) Moisture Fines (%) Description B-4 S-1 2Y2 - 4 8.9 35.3 Silty SAND Project No.: 1151.01 PROJECT NAME: Zipper Geo Associates, LLC DATE OF TESTING: 7/13/2013 Geotechnical and Environmental Consultants Prestige Care is 0 GRAIN SIZE ANALYSIS Test Results Summary ASTM D 422 100 �Ef 80 70 ca W 60 LU z 50 z LU C.)

Included in this Operation and Maintenance Manual is an 11" x 17" grading and drainage plan sheet showing the location of these facilities on the plan. Please note that this map is generated during the design phase and may not reflect all changes made in permitting and construction. CG Engineering may be contacted for an updated copy of this map once the as -built drawings are completed for the site. The contractor on the project will be Exxel Pacific. Prestige Care will be responsible for the maintenance of the on -site storm system per this manual. This manual shall be kept in the Prestige Care building's offices. Upon request by the City of Edmonds, it shall be made available for their inspection. The current responsible owner for the manual is to be TJ Mellama with Exxel Pacific. He will be responsible for providing this manual to the Facilities Manager of the proposed building and contacting CG Engineering to update the contact information in this report. Included in this manual are facility -specific sheets indicating the various maintenance components of the following facilities: Catch Basins: Catch basins are concrete structures with steel grates that collect stormwater runoff from the site and act as junctions for storm conveyance pipes. Conveyance Pipes: Conveyance pipes will route runoff to appropriate locations as shown on the plan sheets. Perk Filters: Perk Filters are located in manholes upstream of the detention vault and are designed to treat the stormwater prior to detention. Detention Vault: The detention vault is a large concrete vault designed to store stormwater and slowly release it into the City storm sewer. Facilities shall be inspected for defects listed in the following facility sheets. Most maintenance tasks are generally reactionary to a defect being found, rather than a matter of constant upkeep. It is generally expected that few to none of these defects will be present upon the yearly inspection of each facility. The facility sheets list the potential conditions warranting maintenance and the expected result following any maintenance. Several engineer's notes for specific tasks are provided within the facility sheets. Unless otherwise noted on the facility sheets the maintenance tasks should be performed on an "as needed" basis: (a) when 4W 2504 th Ave South, Suite 200 0 Edmonds, WA 98020 ENGINEERING Stormwater Site Plan Report CG Project #13073.20 E 0 the described defect is visible to whomever performs the yearly inspection, or (b) should any defect become apparent between inspections.

NOTE: KCC 27A authorizes right of way and site restoration bonds to be combined when both are required. The restoration requirement shall include the total cost for all TESC as a minimum, not a maximum. In addition, corrective work, both on- and off -site needs to be included. Quantities shall reflect worse case scenarios not just minimum requirements. For example, if a salmonid stream may be damaged, some estimated costs for restoration needs to be reflected in this amount. The 30% contingency and mobilization costs are computed in this quantity. NOTE: Per KCC 27A, total bond amounts remaining after reduction shall not be less than 30% of the original amount (T) or as revised by major design changes.
