Because the addition did not exceed the threshold requiring review by the Architectural Design Board (ADB), staff completed the review with the building permit application under file number ADB-2008-0044. The project involves a second floor office addition to an existing office building at 547 Dayton Street in the BD-2 zone (Downtown Mixed Commercial Comprehensive Plan Designation). A pre -application meeting was held on 04.19.06. There are no critical areas on or adjacent to the property (CRA-2008-0036). Review under the State Environmental Policy Act (SEPA) is not required for this project. The project proposes to meet all required development standards (setbacks, height, parking, etc.). There are no required setbacks, and there is no room for any additional landscaping (see photos of the exterior of the site, attached). With respect to the design criteria in the Comprehensive Plan and in ECDC 16.43.030, the proposal is APPROVED with conditions: 1. All existing landscaping around the perimeter of the site is to remain. 2. The new addition shall be painted to match the existing exterior. 3. Any future changes to the site or to the exterior of the building shall be reviewed by the Planning Division for compliance with ECDC 20. 10 and ECDC 16.43.

I - - 0 0 Geotechnical Engineering Evaluation Jantz Office Addition Edmonds, Washington INTRODUCTION This report presents the results of our geotechnical engineering investigation and evaluation of the proposed Jantz office building addition located at 547 Dayton Avenue in Edmonds, Washington, as shown on the Vicinity Map in Figure 1. The purpose of this study is to explore and characterize the site's surface and subsurface conditions, and to provide geotechnical recommendations for site development. For our use in preparing this report, we were provided with site plans titled "An Addition to the Office Building for Gregory Jantz — 547 Dayton Street — Edmonds, WA," dated January 9, 2008, prepared by Warren LaFon Architect, showing the existing site conditions and planned improvements. The site is currently occupied by a two-story office building. Development plans include the construction of a new 2-story addition with a slab -on -grade in the northwestern portion of the property. Stormwater is planned to be directed into an existing system. The proposed site layout is shown on the Site Plan in Figure 2. ISCOPE The purpose of this study is to explore and characterize the site subsurface conditions, and provide for development. Specifically, includes general recommendations site our scope of services the following: 1. Review available soil and geologic maps of the area. 2.

I NELSON GEOTECHNICAL ASSOCIATES, INC. I (3eotechnical Engineering E&ation Jantz Office Addition Edmonds, Washington March 28, 2008 NGA File No. 784908 Page 2 SITE CONDITIONS Surface Conditions The property is rectangular -shaped and is approximate 0.15-acre in size. The property is currently occupied by a 2-story office building. The property is bordered to the north by an alley, to the east and west by commercial/office buildings, and to the south by Dayton Avenue. The new development is planned in the northwestern portion of the property. The project area is currently unoccupied, and covered with asphalt and landscaping areas. We did not observe any standing water during our site visit on Friday, March 14, 2008. Subsurface Conditions Geology: The geologic units for this site are shown on the Geologic Map of the Edmonds East and Part of the Edmonds West Quadrangles, Snohomish Counly, Washington, by James P. Minard (USGS 1983). The site is mapped as transitional beds (Qtb) and Advance Outwash (Qva). The transitional beds are described as clay, silt and fine sand, and the advance outwash soils are descried as mostly clean, pebbly sand. Our explorations encountered silty sand with gravel generally consistent with the description of Iadvance outwash. Explorations: The subsurface conditions within the site were explored on March 14, 2008 by performing one hand auger to a depth of 5.5 feet below the existing ground surface. The approximate location of our exploration is shown on the Site Plan in Figure 2. A geologist from NGA was present during the explorations, examined the soils and geologic conditions encountered, obtained samples of the different soil types, and maintained a log of the hand auger. The soils were visually classified in general accordance with the Unified Soil. Classification System, presented in Figure 3. The log of our hand auger is attached to this report and is presented as Figure 4. We present a brief summary of the subsurface conditions in the following paragraph. For a detailed description of the subsurface conditions, the log of the hand auger should be reviewed. At the surface of Hand Auger 1, we encountered approximately 0.5 feet of medium dense, dark brown, fine to coarse sand with gravel which we interpreted to be topsoil. Below the topsoil, we encountered NELSON GEOTECHNICAL ASSOCIATES, INC. I Oeotechnical Engineering Akation Jantz Office Addition Edmonds, Washington March 28, 2008 NGA File No. 784908 Page 3 approximately 2.5 feet of medium dense, brown, fine to medium sand with gravel which we interpreted to be modified ground. Below the modified ground, we encountered light brown, medium dense, silty fine to coarse sand with gravel, which we interpreted to be native advance outwash. Hand Auger I was terminated in the advance outwash at a depth of 5.5 feet below the existing ground surface. Hydrologic Conditions Groundwater seepage was not encountered in the hand auger. However, perched groundwater may occur on the site during extended periods of wet weather. Perched water occurs when surface water infiltrates through less dense, more permeable soils and accumulates on top of underlying, less permeable soils. Perched water does not represent a regional groundwater "table" within the upper soil horizons. Perched water tends to vary spatially and is dependent upon the amount of precipitation. We would expect the amount of perched water to decrease during drier times of the year and increase during wetter periods. SENSITIVE AREA EVALUATION Seismic Hazard We reviewed the 2006 International Building Code (IBC) for seismic site classification for this project. Since medium dense soil was encountered underlying the site at depth, the site conditions best fit the IBC description for Site Class D. Hazards associated with seismic activity include liquefaction potential and amplification of ground motion. Liquefaction is caused by a rise in pore pressures in a loose, fine sand deposit beneath the groundwater table. . It is our opinion that the competent advance outwash interpreted to underlie the site has a low potential for liquefaction or amplification of ground motion. Erosion Hazard The criteria used for determination of the erosion hazard for affected areas include soil type, slope gradient, vegetation cover, and groundwater conditions. The erosion sensitivity is related to vegetative cover and the specific surface soil types, which are related to the underlying geologic soil units. The Soil Survey of Snohomish County Area, Washington, by the Soil Conservation Service (SCS) was reviewed to determine the erosion hazard of the on -site soils. The surface soil for this site was mapped as Alderwood NELSON GEOTECHNICAL ASSOCIATES, INC. 6eotechnical Engineering Aation 0 Jantz Office Addition Edmonds, Washington March 28, 2008 NGA File No. 784908 Page 4 Urban land complex, 2 to 8 percent slopes. The erosion hazard for this material is listed as slight. It is our opinion that the erosion hazard for site soi Is should be low in areas where the site is not disturbed. LABORATORY ANAYLYSIS We performed one grain -size sieve analysis on a soil samples from the hand auger. The results of the sieve analysis is presented as Figure 5. CONCLUSIONS AND RECOMMENDATIONS General It is our opinion from a geotechnical standpoint that the site is compatible with the planned development. Our explorations indicated that the site is generally underlain by competent native advance outwash soils. However, we did encounter small areas of modified ground in the area of our exploration, indicating that previous grading activities may have occurred on the site, possibly during the construction of the existing building. The modified ground should be re -compacted, or replaced with structural fill. The native soils should provide adequate support for foundation, slab, and pavement loads. We recommend that the building be designed utilizing shallow foundations. Footings should extend through and loose soil, and be founded on the underlying medium dense or better native soil, or structural fill extending to these soils. The medium dense or better soil should typically be encountered approximately two feet below the existing surface, based on our explorations. The upper soils encountered on this site are considered moisture -sensitive, and may disturb when wet. We recommend that construction take place during the drier summer months, if possible. If construction is to take place during wet weather, the soils may disturb and additional expenses and delays may be expected due to the wet conditions. Additional expenses could include the need for placing a blanket of rock spalls to protect exposed subgrades and construction traffic areas. The native on -site soils could be used as structural fill provided they could be compacted to specifications. This will depend on the moisture content of the soils at the time of construction. NGA should be retained to determine if the on - site soils can be used as structural fill material during construction. I I NELSON GEOTECHNICAL ASSOCIATES, INC. I 'Geotechnical Engineering Aation 0 Jantz Office Addition Edmonds, Washington March 28, 2008 NGA File No. 784908 Page 5 Erosion Control The erosion hazard for the on -site soils is listed as slight for exposed soils, but actual erosion potential will be dependent on how the site is graded and how water is allowed to concentrate. Best Management Practices (BMPs) should be used to control erosion. Areas disturbed during construction should be protected from erosion. Erosion control measures may include diverting surface water away from the stripped or disturbed areas. Silt fences and/or straw bales should be erected to prevent muddy water from leaving the site. Disturbed areas should be planted with vegetation or paved as soon as practical. The erosion potential of areas not stripped of vegetation or where pavement is removed should be low. Site Preparation and Grading After erosion control measures are implemented, site preparation should consist of removing the asphalt and loose soils from the building and other structural areas to expose medium dense or better native soils. This material should be cleaned of organics and other debris and then be stockpiled for re -use as structural fill. Our exploration generally encountered medium dense or better native soils approximately two feet below the existing ground surface. However, additional stripping may be required if areas of undocumented fill and/or loose soil are encountered in unexplored areas of the site. We recommend that the modified ground found in the building and pavement areas be reworked to structural fill specifications. After removing the asphalt and loose soils, if the exposed subgrade appears to be loose, it should be compacted to a non -yielding condition and then proof -rolled with a heavy rubber -tired piece of equipment. Areas observed to pump or weave during the proof -roll test should be reworked to structural fill specifications or over -excavated and replaced with properly compacted structural fill or rock spalls. If loose soils are encountered in the pavement areas, the loose soils should be removed and replaced with rock spalls or granular structural fill. If significant surface water flow is encountered during construction, this flow should be diverted around areas to be developed, and the exposed subgrades should be maintained in a semi -dry condition. The upper site soils are considered moisture -sensitive, and may disturb when wet. We recommend that construction take place during the drier summer months if possible. However, if construction takes place NELSON GEOTECHNICAL ASSOCIATES, INC. i3eotechnical Engineering Aation 0 Jantz Office Addition Edmonds, Washington March 28, 2008 NGA File No. 784908 Page 6 during the wet season, additional expenses and delays should be expected due to the wet conditions. Additional expenses could include the need for placing a blanket of rock spalls on exposed subgrades, construction traffic areas, and paved areas prior to placing structural fill. Wet weather grading will also require additional erosion control and site drainage measures. The existing material may be partially suitable for use as structural fill. The underlying native soils may be suitable for use as structural fill, depending on the moisture content of the soil at the time of construction. NGA should be retained to evaluate the suitability of all on -site and imported structural fill material during construction. Temporary Slopes We do not anticipate tall cuts for this project, but cuts may be needed for utility installation. Temporary cut slope stability is a function of many factors, including the type and consistency of soils, depth of the cut, surcharge loads adjacent to the excavation, length of time a cut remains open, and the presence of surface or groundwater. It is exceedingly difficult under these variable conditions to estimate a stable, temporary, cut slope angle. Therefore, it should be the responsibility of the contractor to maintain safe slope configurations at all times as indicated in OSHA guidelines for cut slopes. The following information is provided solely for the benefit of the owner and other design consultants and should not be construed to imply that Nelson Geotechnical Associates, Inc. assumes responsibility forjob site safety. Job site safety is the sole responsibility of the project contractor. For planning purposes, we recommend that temporary cuts in the near surface loose to medium dense material be no steeper than 2 Horizontal to I Vertical (2H: IV). The underlying dense outwash could be excavated at a IRIV inclination. If significant groundwater seepage or surface water flow were encountered, we would expect that flatter inclinations would be necessary. We recommend that cut slopes� be protected from erosion. The slope protection measures may include covering cut slopes with plastic sheeting and diverting surface runoff away from the top of cut slopes. We do not recommend vertical slopes for cuts deeper than four feet, if worker access is necessary. We recommend that cut slope heights and inclinations conform to appropriate OSHA/WISHA regulations. NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Atiation Jantz Office Addition Edmonds, Washington March 28, 2008 NGA File No. 784908 Page 7 Foundations Conventional shallow spread foundations should be placed on medium dense or better native soils, or be supported on structural fill or rock spalls extending to those soils. Medium dense soils should be encountered approximately two feet below ground surface based on our explorations. Where undocumented fill or less dense soils are encountered at foot ing bearing elevation, the subgrade should be over -excavated to expose suitable bearing soil. The over -excavation may be filled with structural fill, or the footing may be extended down to the competent native soils. If footings are supported on structural fill, the fill zone should extend outside the edges of the footing a distance equal to one-half of the depth of the over -excavation below the bottom of the footing. Footings should extend at least 18 inches below the lowest adjacent finished ground surface for frost protection and bearing capacity considerations. Foundations should be designed in accordance with the 2006 IBC. Footing widths should be based on the anticipated loads and allowable soil bearing pressure. Water should not be allowed to accumulate in footing trenches. All loose or disturbed soil should be removed from the foundation excavation prior to placing concrete. For foundations constructed as outlined above, we recommend an allowable design bearing pressure of not more than 2,000 pounds per square foot (psf) be used for the design of footings founded on the medium dense or better native soils or structural fill extending to the competent native material. The foundation bearing soil should be evaluated by a representative of NGA. We should be consulted if higher bearing pressures are needed. Current IBC guidelines should be used when considering increased allowable bearing pressure for short-term transitory wind or seismic loads. Potential foundation settlement using the recommended allowable bearing pressure is estimated to be less than one -inch total and '/2-inch differential between adjacent footings or across a distance of about 20 feet, based on our experience with similar projects. Lateral loads may be resisted by friction on the base of the footing and passive resistance against the subsurface portions of the foundation. A coefficient of friction of 0.35 may be used to calculate the base friction and should be applied to the vertical dead load only. Passive resistance may be calculated as a triangular equivalent fluid pressure distribution. An equivalent fluid density of 200 pounds per cubic foot (pcf) should be used for passive resistance design for a level ground surface adjac ent to the footing. This level surface should extend a distance equal to at least three times the footing depth. These recommended NEL SON GEO TECHNICA L A SSO CIA TES, INC. Geotechnical Engineering Aation 0 Jantz Office Addition Edmonds, Washington March 28, 2008 NGA File No. 784908 Page 8 values incorporate safety factors of 1.5 and 2.0 applied to the estimated ultimate values for frictional and passive resistance, respectively. To achieve this value of passive resistance, the foundations should be poured "neat" against the native medium dense soils or compacted fill should be used as backfill against the front of the footing. We recommend that the upper one -foot of soil be neglected when calculating the passive resistance. Structural Fill General: Fill placed beneath foundations, pavement, or other settlement -sensitive structures should be placed as structural fill. Structural fill, by definition, is placed in accordance with prescribed methods and standards, and is monitored by an experienced geotechnical professional or soils technician. Field monitoring procedures would include the perfon-nance of a representative number of in -place density tests to document the attainment of the desired degree of relative compaction. The area to receive the fill should be suitably prepared as described in the Site Preparation and Grading subsection prior to beginning fill placement. Materials: Structural fill should consist of a good quality, granular soil, free of organics and other deleterious material, and be well graded to a maximum size of about three inches. All-weather structural fill should contain no more than five percent fines (soil finer than U.S. No. 200 sieve, based on that fraction passing the U.S. 3/4-inch sieve). The on -site soils may be suitable for use as structural fill depending on the moisture, debris, and organic content of the soil during construction. We should be retained to evaluate all proposed structural fill material prior to placement. Fill Placement: Following subgrade preparation, placement of structural fill may proceed. All filling should be accomplished in uniform lifts up to eight inches thick. Each lift should be spread evenly and be thoroughly compacted prior to placement of subsequent lifts. All structural fill underlying building areas and pavement subgrade should be compacted to a minimum of 95 percent of its maximum dry density. Maximum dry density, in this report, refers to that density as determined by the ASTM D-1557 Compaction Test procedure. The moisture content of the soils to be compacted should be within about two percent of optimum so that a readily compactable condition exists. It may be necessary to over - excavate and remove wet soils in cases where drying to a compactable condition is not feasible. All compaction should be accomplished by equipment of a type and size sufficient to attain the desired degree of compaction. NELSON GEOTECHNICAL ASSOCIATES, INC. 'Geotechnical Engineering Aation Jantz Office Addition Edmonds, Washington March 28, 2008 NGA File No. 784908 Page 9 Slab -on -Grade Slabs -on -grade should be supported on subgrade soils prepared as described in the Site Preparation and Grading subsection of this report. We recommend that all floor slabs be underlain by at least six inches of free -draining gravel with less than three percent by weight of the material passing Sieve #200 for use as a capillary break. We recommend that the capillary break be hydraulically connected to the footing drain system to allow free drainage from under the slab. A suitable vapor barrier, such as heavy plastic sheeting (6-mil minimum), should be placed over the capillary break material. An additional 2-inch thick moist sand layer may be used to cover the vapor barrier. This sand layer is optional and is intended to protect the vapor barrier membrane during construction. Pavements Pavement subgrade preparation, and structural filling where required, should be completed as recommended in the Site Preparation and Grading and Structural Fill subsections of this report. The pavement subgrade should be proof -rolled with a heavy, rubber -tired piece of equipment, to identify soft or yielding areas that require repair. We should be retained to observe the proof -rolling and recommend repairs prior to placement of the asphalt or hard surfaces. Site Drainage Surface Drainage: The finished ground surface should be graded such that storinwater is directed to an appropriate stormwater collection system. Water should not be allowed to stand in any areas where footings, slabs, or pavements are to be constructed. Final site grades should allow for drainage away from the structures. We suggest that the finished ground be sloped at a minimum gradient of three percent, for a distance of at least 10 feet away from the structures. Surface water should be collected by permanent catch basins and drain lines, and be discharged into an appropriate discharge system. Subsurface Drainage: If groundwater is encountered during construction, we recommend that the contractor slope the bottom of the excavation and collect the water into ditches and small sump pits where the water can be pumped out and routed into a permanent storm drain. We recommend the use of footing drains around the structure. Footing drains should be installed at least one foot below planned finished floor elevation. The drains should consist of a minimum four -inch - NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Aation Jantz Office Addition Edmonds, Washington March 28, 2008 NGA File No. 784908 Page 10 diameter, rigid, slotted or perforated, PVC pipe surrounded by free -draining material wrapped in a filter fabric. We recommend that the free -draining material consist of an 18-inch-wide zone of clean (less than three -percent fines), granular material placed along the back of walls. Pea gravel is an acceptable drain material, or drainage composite may also be used instead. The free -draining material should extend up the wall to one foot below the finished surface. The top foot of backfill should consist of impermeable soil placed over plastic sheeting or building paper to minimize surface water or fines migration into the footing drain. Footing drains should discharge into tightlines leading to an appropriate collection and discharge point with convenient cleanouts to prolong the useful life of the drains. Roof drains should not be connected to wall or footing drains. USE OF THIS REPORT NGA has prepared this report for Warren LaFon Architect and their agents for use in the planning and design of the development on this site only. The scope of our work does not include services related to construction safety precautions and our recommendations are not intended to direct the contractors' methods, techniques, sequences, or procedures, except as specifically described in our report for consideration in design. There are possible variations in subsurface conditions outside the locations of the exploration. Our report, conclusions, and interpretations should not be construed as a warranty of subsurface conditions. A contingency for unanticipated conditions should be included in the budget and schedule. We recommend that NGA be retained to provide monitoring and consultation services during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether or not earthwork and foundation installation activities comply with contract plans and specifications. We should be contacted a minimum of one week prior to construction activities and could attend pre -construction meetings if requested. Within the limitations of scope, schedule, and budget, our services have been performed in accordance with generally accepted geotechnical engineering practices in effect in this area at the time this report was prepared. No other warranty, expressed or implied, is made. Our observations, findings, and opinions are a means to identify and reduce the inherent risks to the owner.
