(HWA) provided construction observation, inspection and testing services for the 76th Ave W/75th Place Walkway and 162"d St SW Project, in Edmonds, Washington. These services were provided in accordance with our proposal dated February 17, 2009 and supplement dated February 8, 2010, and consisted of both periodic and continuous construction monitoring and site inspection during various construction stages of the subject project. This report summarizes the results of HWA's monitoring and testing during construction of various components of the project falling within our work scope. Our daily field inspection reports and geotechnical engineering laboratory test results are compiled in the attached Appendices A and B, respectively. Portland Cement Concrete (PCC) and Hot Mix Asphalt (HMA) laboratory test results, which include determination of binder content, aggregate size distribution and maximum theoretical density (Rice Density), are compiled in the attached Appendices C and D, respectively. PROJECT DESCRIPTION AND HWA WORK SCOPE The approximate project location is shown on the Vicinity Map (Figure 1). The project included construction of retaining walls (soldier pile walls, rockeries, gravity block and modular block walls) and curb and gutter installation along 761h Avenue W and 75th Place; and a new park at 162d Street SW, with an elevated walkway along 75th Place. ' HWA provided construction observation and testing services on the project starting on August 8, 2009. That work consisted of providing full-time and part-time construction 21312 30th Drive SE monitoringand inspection of rebar and concrete placement, Suite 110 p p ,grading and trench Bothell, WA 98021.7010 backfill construction. Inspection and monitoring was provided during the Tel: 425.774.0106 Fax: 425.774.2714 ' www.hwageo.com i August 6, 2010 HWA Project No. 2006-171-21 installation of retaining walls and for pin piles for the elevated sidewalk. Our work also included compaction testing and inspection of native soils, crushed surfacing base course (CSBC), crushed surfacing top course (CSTC), and Hot Mix Asphalt (HMA) Class '/2" asphalt paving. The last visit by HWA personnel to the work site was on July 15, 2010. HMA Placement and Compaction HMA Class'/2" mix was used for paving surfaces in the park and along the street. The mix originated from the CEMEX asphalt plants in Everett and Kenmore, Washington. All HMA sampling and laboratory testing were performed by HWA. Laboratory testing consisted of determination of binder content, aggregate size distribution and maximum theoretical density (Rice Density). HWA's laboratory provided field personnel with the results of the maximum theoretical density (Rice Density) for use during the paving operations and for field reports. Continuous observation and testing were provided during the asphalt paving operations. Welding Welding of the elevated sidewalk panels to pin piles was inspected by HWA personnel and inspected to AWS D1.1 Code and job site specifications. Portland Cement Concrete Six concrete design mixes; (#1189027) 3000-psi strength compressive design from CEMEX p � g (#M20120) 1,000-psi compressive strength design from Salmon Bay Sand and Gravel, (#3136 and #1997) 3,000-psi compressive strength design from Cal Portland, (#3717) 4,000-psi compressive strength design from Glacier and (#1517) 5,000-psi compressive strength design from CEMEX were used for the different phases of this project. Mix designated M20120 (CDF) failed to meet the 1,000-psi as initially required however, the engineer waived the 1,000-psi and replaced it with a 300-psi requirement. As required, an HWA inspector tested fresh PCC mixes and monitored their placement. PCC sampling was conducted in general accordance with ASTM C 172. Slump, temperature and air ' content parameters were measured in the field in general accordance with ASTM C 143, C 1064 and C 231, respectively. Four -inch diameter by eight -inch long cylindrical specimens and Six- inch diameter by twelve -inch long cylindrical specimens were cast per ASTM C 31. Test specimens were placed in insulated boxes, which remained on -site usually for 24 hours until being transported to HWA's laboratory for further curing and compressive strength testing. The ' results of these tests are included in Appendix C. All tested PCC mixes met the requirements set by the specifications of the project, as indicated in the test reports. Other Material Laboratory Testing In addition to the testing outlined in the previous paragraphs, representative aggregate samples were obtained from Aggregate suppliers and returned to HWA's laboratory for further ' Inspection Final Report 2 HWA GeoSciences Inc. I August 6, 2010 HWA Project No. 2006-171-21 examination and testing. Laboratory tests were conducted on the selected aggregate samples to characterize relevant physical properties, including grain size distribution, moisture -density ' relationship (Modified Proctor), sand equivalent and/or fracture face count. The results of all material laboratory tests are summarized and attached in Appendix B of this ' report. OUTSTANDING ISSUES tAll identified issues were resolved by the end of the project with the exception of under - compacted Hot Mix Asphalt pavement placement as described in Field Report FR-066. Our field reports are attached in Appendix A and Field Report FR-066 shows the only outstanding issue being un-resolved. There are no other outstanding issues that HWA is aware of. Based on HWA's observations and the results of the testing reported herein, it is our conclusion that the different components of construction observed during the various stages of construction along 76t'' Ave W/75t" Place and on 162°d St SW Project in Edmonds, Washington, were carried out in general compliance with the drawings and project specifications. CONDITIONS AND LIMITATIONS Our construction observations and tests on subgrade, aggregate, HMA pavement, PCC, Welded ' connections, construction of various retaining walls as described in this report, are based on periodic and/or continuous services as required during construction. All special inspections were monitored and performed by certified inspectors as necessary. The compressive strength results of PCC cylinders reported are specific to the cylinder specimens prepared and are dependent on many variables such as specimen density and method of densification employed. The compaction testing results reported for aggregate and HMA pavement are dependent upon the equipment and placement/compaction methods used, weather conditions, and specific locations tested. Experience has shown aggregate and HMA compaction conditions can vary significantly over small distances. References to elevations and locations of tests herein are based on grade checker's stakes in the field and/or interpolation from project plans. HWA did not provide surveying services and, therefore, cannot comment upon the accuracy/appropriateness of the as -graded elevations or surface geometry with respect to the project plans. Our conclusions and opinions as to whether the work essentially complies with the job specifications are based on our observations and test results, and on our general experience. The conclusions presented herein apply only to our work with respect to the specific phases of the project, and represent conditions at the end of our final observation during construction on July Inspection Final Report 3 HWA GeoSciences Inc. 1 August 6, 2010 HWA Project No. 2006-171-21 15, 2010. We cannot provide advice, opinions or speculate on site conditions relative to wo that we have not observed. Within the limitations of scope, schedule and budget, HWA attempted to provide construction - monitoring and testing services in accordance with generally accepted professional principles and practices in this field. HWA does not practice or consult in the field of safety engineering. We did not direct the contractor's operations, and cannot be held responsible for the safety of field personnel other than our own on the site. As such, the safety of others was the responsibility of the contractor. We trust that the foregoing summary of our inspection services meets with your requirements and ' we appreciate the opportunity to have been of service to you on this project. Should you have any questions, or if we may be of additional service, please call at your convenience. Sincerely, HWA GEOSCIENCES INC.

CONFORMANCE OF THIS ITEM: To the best of the inspector's knowledge, the item inspected was found in conformance with approved plans, specifications and RFIs. MISCELLANEOUS ACTIVITIES, OBSERVATIONS AND/OR COMMENTS: HWA observed the contractor place 2 feet of AG-2 CSBC over and around the 12" storm pipe followed by a 1 foot lift. Compaction was obtained on each lift using a steel vibratory plate attachment on a Case 580 backhoe. Heavy compaction effort was exerted to the point of causing the backhoe outriggers- to come off the ground. HWA observed the contractor place clean crushed rock in each block cell and on top of the Geo-grid fabric behind the modular block wall every second layer of block followed by AG-2 CSBC. This work was located in the park between approximate locations 0+00 to 1+55. Compaction was obtained using a plate compactor and material was compacted after each course of block was applied. ' It should be noted that C.B.11 location was changed from the approved plans and was approved per Ed with the City of Edmonds. The plans call for the C.B. to be 8 inches from the corner of the elevated sidewalk wall, but because the footing was too high, the C.B. 11 was relocated 3 feet from the corner of the elevated sidewalk.

INTRODUCTION This report presents geotechnical recommendations for design and construction of the proposed walkway improvements to 76th Avenue West and 75th Place West in Edmonds, Washington. The purpose of this work was to assess geotechnical conditions along the project alignment and provide recommendations for design and construction of the proposed improvements. 1.1 Site and Project Description The project is located in the Meadowdale area of Edmonds, which is located along the shoreline of Puget Sound north of the city. The area is indicated on the Vicinity Map, Figure 1. The project will include construction of a walkway along 76th Avenue West and 75th Place West extending from Meadowdale Beach Road north to North Meadowdale Road, with some additional improvements north to the King County Park. The project will include development of a park at the north-west corner of 75th Place West and 162° Street SW. Three conceptual designs for the proposed improvements were developed during preliminary studies. We understand Concept 1 was selected for final design and construction. Under the selected concept, the new sidewalk will be located along the east (upslope) side of the roadway from Meadowdale Beach Road north to 162" d Street SW. Cuts into the hillside will be required for the new sidewalk in much of this area. The cuts will be typically 3 to 4 feet in height but will be up to 12 feet high in some areas. From 162nd Street SW north to North Meadowdale Road the new walkway will be located on the ' western side of the road. Since placing fill along the top of the slope could reduce the stability of the slope and is to be avoided, the new sidewalk will be supported on small diameter pipe piles where there is insufficient existing flat area. North of North Meadowdale Road two pull-outs will be constructed on the east side of the road for vehicle parking, and one 130-foot-long section of pile -supported walkway is planned on the west side of the road. Development of the proposed park will include regrading the site and construction of a driveway, walkways, lawn and play areas. We understand an interpretive overlook is planned adjacent to 75th Place West. A plan of the proposed park is presented on Figure 6. May 30 2008 HWA Project No. 2006-171-21 2. EXPLORATIONS AND GEOLOGIC CONDITIONS 2.1 Subsurface Explorations ' Subsurface. information for the project was obtained by advancing three hollow stem auger borings designated BH-1 through BH-3; nine hand borings designated HH-1 through HH-9; and three DCP soundings performed in concert with hand borings HH-7 HH-8 and HH-9. Boring BH-1 was conducted by Davies Drilling Inc. using a track mounted CME-75 drill rig with a 3.25 inch OD hollow stem auger. Borings BH-2 and BH-3 were drilled by Environmental Drilling using a truck mounted B-61 drill rig with an 8 inch OD hollow stem auger. ' BoringBH-1 is located in the northeast section of the proposed new ark. Borings BH-2 and p p p g BH-3 are located along the pr7osed sidewalk alignment where a new solider pile wall will be installed on the east side of 76 Avenue West and 75t' Place West. Hand holes HH-1 through HH-6 are located along the east side of 76th Avenue West and 75u' Place West along the alignment of the proposed sidewalk. Hand holes H 1-7 through HH-9 along with their associated DCP soundings are located along the west side of 75t' Place west between 162" a Street West and North Meadowdale beach road. Borings were advanced either at the edge the City right of way, or in the middle of the right travel lane, as shown in Figures 2-4. A 2-inch diameter ground water monitoring well was installed in BH-2 with screen from a depth of 15 to 25 feet and a silica sand filter from a depth of 12 to 30 feet. A slope inclinometer casing was installed in BH-1 after the completion of the boring. The casing was installed to a depth of 35 feet below the ground surface and was incased in cement grout. A baseline reading for future measurements was taken on October 24ffi 2007. Readings were subsequently taken February 22, 2008. Plots of the readings from BH-1 are presented on Figure 10. Borings were located using a site map provided by Gray & Osborne inc. by measuring from existing structures shown on the base map provided. A legend of the terms and symbols used on the boring logs is presented in Figure A-1. Summary boring logs are presented in Figures A-2 through A-13 . Standard Penetration tests were performed at 2.5-foot or 5-foot intervals in all three borings. The Standard Penetration test consists of driving a 2-inch O.D. split -spoon sampler a distance of 18 inches into the bottom of the borehole with a 140-pound hammer falling 30 inches. The number of blows required driving the sampler each of three 6-inch increments was recorded, and number of blows required to cause the last 12 inches of penetration was termed the Standard Penetration Resistance (N-value). This value is an indicator of the relative density or consistency of the soils. Whenever 50 or more blows were required to cause 6 inches of penetration, driving was stopped and the number of blows and corresponding penetration were recorded. Samples recovered from the split spoon sampler were disturbed but were representative of the soils encountered. 1 200617121 Revised Geotechnical Report.doc 2 HWA GeoSciences Inc. May 30 2008 HWA Project No. 2006-171-21 An HWA geologist monitored the drilling and logged the borings. Soil samples were obtained from the borings at intervals of 2.5 to 5.0 feet, classified in the field, and representative portions were placed in plastic bags. These soil samples were taken to our Lynnwood, Washington, laboratory for further examination and testing. Pertinent information including soil sample depths, stratigraphy, soil engineering characteristics, and ground water occurrence were recorded on the exploration logs. The stratigraphic contacts shown on the individual boring logs represent the approximate boundaries between soil types; actual transitions may be more gradual. The soil ' and ground water conditions depicted are only for the specific date and locations reported and, therefore, are not necessarily representative of other locations and times. 2.2 General Geologic Conditions Geologic information for the project site was obtained from the published geologic map for the area; Booth, D. B., Cox, B. F., Troost, K. G., and Shimel, S. A., 2004, Composite geologic map of the Sno-King area: University of Washington, Seattle Area Geologic Mapping Project, scale 1:24,000. This map indicates that the surficial geology of the area consists of Pre -Fraser terrestrial deposits, overlain by Vashon-stade advance outwash, a unit of mostly clean sand with some gravel, overlain by Vashon-stade glacial till a non -stratified and non -sorted mixture of clay, silt, sand, and gravel. The terrestrial deposits reside mainly in the northern portion of the sidewalk alignment while the till and advance deposits are seen in the southern portion of the alignment. The area is also overlain by landslide colluvium deposited by the ancient Meadowdale slide. The landslide deposits occur throughout most of the site and are surficial above the glacial and pre -glacial terrestrial deposits. 2.3 Landslide History The majority of the project alignment lies within the North Edmonds Earth Subsidence and Landslide Hazard Area, which is described in detail in a report titled "Landslide Hazards Investigation, Meadowdale Area, Edmonds, Washington" prepared by Roger Lowe Associates in 1979. According to the Roger Lowe Associates report, this area of Meadowdale experienced large- scale ground movement between two and three thousand years ago. This slide was approximately 3,200 feet long and up to 650 feet wide. The head scarp is easily distinguishable above 751h Place West. The cause of this large-scale earth movement is inferred to be progressive shoreline erosion by wave action; the waves eroded the toe of the slope, which over - steepened it and evenwally led to land sliding. Construction of the Great Northern Railroad, which is currently owned by Burlington Northern Santa Fe, along the beach, has halted the shoreline erosion process since ii armors the toe of the slope from wave erosion. tNo large-scale earth movements have been recorded for this area in modern times. However, subsequent to the ancient slide, the mass of soil within the body of the slide has experienced numerous small-scale adjustments. This type of post -slide adjustment is common and typically occurs in the form of shallow earth slumps. 1 200617121 Revised Geotechnical Report.doc 3 HWA GeoSciences Inc. May 30 2008 HWA Project No. 2006-171-21 More recently, sliding occurred in the area in January 1997, after heavy snowfall was followed immediately by several inches of rain. Sliding occurred at several locations on the eastern side of 75 h Place West and debris from one slide flowed across the street and came to rest on the western side the road. Landslides occurred throughout the Puget Sound Region at that time and are described in more detail in the paper by Gerstel et al. titled "Puget Sound Bluffs: The Where, Why, and When of Landslides Following the Holiday 1996/97 Storms" (in Washington Geology, vol. 25, no. 1, March 1997). The study by Roger Lowe Associates also indicates that the stability of the Meadowdale area is highly sensitive to groundwater levels. Improvements to local site drainage, including the installation of sewers and storm drains, have had a positive impact on the stability of the area. For several years sliding has been occurring at the northeast corner of the proposed 162na Street park property. This sliding has been very slow, but is visible in cracks and subsidence in the pavement of 75t' Place West. HWA has been monitoring this slide for several years for the property owner to the north of the park. HWA installed an inclinometer casing in the shoulder of 75t' Place West several years ago. Measurements in this casing indicate a shear plane at depths of 16 to 20 feet. The toe of the slide appears to be at the base of the steep portion of the slope. 2.4 Subsurface Conditions Based on the results of our exploration program, the soils underlying the project area were observed to consist of Pre -Fraser terrestrial deposits overlain by colluvial deposits and small localized quantities of fill. This observation is consistent with the soils unit mapped in the area by Booth ET. Al., by Roger Lowe Associates, and as encountered during previous drilling undertaken by HWA to evaluate the subsurface conditions for other projects in this area in the ' past. (HWA, 2003). Following are descriptions of the soil deposits encountered in our explorations in the order of stratigraphic (depth) sequence by which they were deposited or placed, with the youngest unit described first. Detailed descriptions of the soils are presented in the exploration logs in Appendix A. A legend of the terms and symbols used on the boring logs is presented in Figure A-1. Summary boring logs are presented in Figures A-2 through A-13. Fill — Fill, consisting of loose to medium dense silty sand to sandy silt was identified in the locations of BH-1, BH-3, HH-1 and HH-7 through HH-9, and ranged from 1.25 to 7 feet thick. The fill was usually identified adjacent to the road, most likely from the grading of the roadway during the initial construction. Topsoil — Topsoil consisting of light brown to dark brow, silty sand with gravel was identified in HH-1 through HH-5. In all of the hand holes the topsoil consisted of loose to medium dense surficial material with abundant roots and rootlets being present. Depths ranged from 0.5 to 2.0 feet in depth. ' 200617121 Revised Geotechnical Report.doc 4 HWA GeoSciences Inc. I L May 30, 2008 HWA Project No. 2006-17I-21 Colluvium — Colluvium was encountered in all of the borings and in hand holes HH-2, HH-6 and HH-9. It generally consisted of very soft to medium stiff clays and silts with interspersed pieces of colluvial clays and silts, with seams of sand. The majority of the colluvium has experienced some oxidation mottling, and the seams of sand tended to be wetter than the surrounding fine grained material. Colluvial Blocks — Colluvial blocks were encountered in Borings 1314-2 and BH-3 under the softer colluvial material that overlies it. In the case of these explorations colluvial blocks refers to disturbed native soils that are denser then the overlying material, but still exhibit some variability in density and an irregularity in the soil that does not correspond with native undisturbed glacial and pre -glacial terrestrial deposits. For example in BH-3 loose poorly graded sand was encountered from 18 to 26 feet between very stiff clay and a hard laminated silt. It is not known when or how these materials were mobilized in the past, but they do exhibit some signs of disturbance. Recessional Outwash — Loose to medium dense glacial outwash consisting of light brown silty sand with gravel to gravelly sand with silt was identified in HH-3 through HH-5. The recessional outwash was encountered on the uphill (east) side of the sidewalk alignment in the area where a slope cut will occur for the new sidewalk. At the locations of TP-1 and TP-16, thin layers of silty sand were encountered from 0.5 to 1.0 foot thick, which appeared to consist of recessional outwash. These soils were loose to medium dense and directly overlie the glacial till. 2.5 Ground Water Conditions Ground water seepage was encountered in borings BH-1, BH-2 and HH-2. We expect, however, that actual ground water depths will vary depending on the season, variation in local subsurface conditions, and other factors. The project alignment is near the toe of the hillside, which is a ground water discharge area. Consequently, springs and seeps occur at numerous locations along the alignment where groundwater emerges from the ground. 2.6 Laboratory Testing Representative soil samples obtained from the subsurface explorations were returned to the HWA laboratory for further examination and testing. Laboratory tests, as described below, were conducted on selected soil samples to characterize relevant engineering properties of the on -site soils. Moisture Content of Soil: The natural moisture.content of all soil samples (percent by dry mass) was determined in general accordance with ASTM D 2216. The results are shown at the sampled intervals on the test pit logs in Appendix A. 200617121 Revised Geotechnical Report.doc 5 HWA GeoSciences Inc. May 30 2008 ' HWA Project No. 2006-171-21 Particle Size Analysis of Soils: Selected samples were tested to determine the particle size distribution of material in general accordance with ASTM D 422. The results are summarized on Figure B-1, Appendix B, which also provides information regarding the classification of the samples and the moisture content at the time of testing. Liquid Limit, Plastic Limit, and Plasticity Index of Soils (Atterberg Limits): Selected samples were tested using method ASTM D 4318, multi -point method. The results are reported on the attached Liquid Limit, Plastic Limit, and Plasticity Index reports, Figure B-2. 3. RECOMMENDATIONS ' 3.1 GENERAL L Construction of a walkway along 76th Avenue West and 75th Place West will require excavation into the toe of the slope on the up -slope (eastern) side of the roadway in some areas, and placement of fill or a pile supported partially -elevated walkway on the downslope side of the road. Because placement of fill on the downslope side of the road would add to the weight of a potential landslide, reducing the stability of the slope, we recommend that filling be avoided to the extent possible. As a result, we recommend that walkways and walkway approach structures on the downslope side of the road be pile -supported wherever there is insufficient existing flat terrain. Development of the propose park will include regrading the site and construction of a driveway, walkways, lawn and play areas. We understand an interpretive overlook is planned adjacent to 75th Place West. Because of the relatively high ground water level and the presence of an existing landslide on the property, we recommend the installation of a trench subdrain across the park. HWA has evaluated measurements taken in an inclinometer casing installed on the park property and performed stability analyses to evaluate the effectiveness of placing a buttressing fill along the toe of the slope. The results of these studies indicate that the existing slide daylights at the toe of the road embankment, and that placement of fill along this toe will increase the stability of the slope. Results of the stability analyses and more detailed recommendations for park design are presented in Section 3.5. 3.2 EARTH RETAINING STRUCTURES Cuts along much of the eastern side of the roadway alignment will be 3 to 4 feet tall. In our ' opinion, the most cost-effective way of retaining these shallow cuts would be with modular block walls such as Keystone blocks, or with rockeries. Block walls up to about 4 feet high (twice the depth of the block) may be made by stacking blocks without need for geogrid reinforcing. Block walls higher than twice the block depth should include geogrid reinforcing which extends back from the face of the wall a horizontal distance equal to at least 0.7 times the free-standing wall height. Geogrid reinforcing should be placed between every second layer of blocks. We recommend the use of Tensar BX1200 geogrid, or equivalent, wherever geogrid reinforcing is needed. ,� 200617121 Revised Geotechnical Report.d6c 6 HWA GeoSciences Inc. May 30 2008 HWA Project No. 2006-171-21 Because of the horizontal space required for block walls, it may be desirable to use soldier pile and lagging walls where the retained height of the cut exceeds about 4 feet. Soldier pile and lagging walls would consist of 4-inch or larger H piles set in concrete in pre -drilled holes. Lagging consisting of treated timber or precast concrete panels would be placed between the soldier piles. The size of the H-pile section would depend on the height of the wall and the horizontal spacing of the piles. Soldier piles should be designed to resist an equivalent fluid I pressure equal to 55 pounds per cubic foot (pcf) plus one pcf for each degree of upward inclination of the backslope. Passive resistance approximated by a 300 pcf equivalent fluid. pressure may be used against the buried portion of structures to resist lateral forces. We . recommend the soldier pile walls be tall enough that the backslope inclination does not exceed 2H to 1 V. Fill could be placed behind the soldier pile walls as necessary to flatten the slope. Soldier piles which are set into concrete in predrilled holes should penetrate below finished grade at least 1.5 times the wall's free-standing height. We do not recommend driving soldier piles because: 1) driving and maintaining pile alignment may be difficult in dense gravelly soils, 2) tvibrations from pile driving can cause landslides, and 3) a concrete -filled hole provides better lateral resistance than a driven pile. Piles which are driven in place would need to extend to a depth equal to twice their free-standing height. Backfill behind the lagging should consist of 1'/4-inch minus crushed rock. Soldier pile and lagging walls constructed as recommended above are typically permeable and will allow the passage of moderate amounts of seepage. Where significant volumes of water are expected, such as at existing springs, a slotted drain pipe and crushed rock backfill should be placed to intercept the flow and convey it through the wall to the storm drain system. 3.3 PILE SUPPORTED WALKWAYS Where pile support of walkways and approach structures is required, we recommend the use of 2-inch diameter extra -strong steel pipe. When driven to less than 1 inch of penetration in 1 ' minute of driving with a 90 psi jackhammer, each pile should be capable of supporting 2 tons of vertical load (allowable capacity) with an adequate factor of safety. Pile installation can actually be accomplished with a backhoe-mounted compactor (hoepac), but testing to verify capacity should be done with a jackhammer. Piles will develop their bearing in native soils below any fill, and pile lengths will vary considerably. Pile lengths could average 20 to 25 feet. 3.4 PAVEMENTS Where new street pavement is required, the pavement subgrade should be proof -rolled to verify 1 that it is dense and unyielding. Any soft or spongy material should be replaced with 1'/4-inch- minus crushed rock. The pavement section should consist of at least 6 inches of crushed rock (CSBC) and 3 inches of asphalt.

May 30 2008 HWA Project No. 2006-171-21 3.5 PARK DESIGN A plan showing the park ropertywith existing ground surface contours and the location on of boring BH-1 is presented on Figure 5. A cross section through the park property showing BH-1, the previous boring HWA-3, and the assumed failure plane of the existing landslide is shown in Figure 7. The proposed layout of park facilities is shown on Figure 6. I3.5.1 Stability ' As indicated on Figure 5, the park property slopes downward from 75th Place West about 2H to 1 V for approximately 20 vertical feet. The site then slopes gradually to 75th Avenue West. Our previous studies indicate that a landslide exists on the north end of the park property and the adjacent property to the north. The slide is still moving as evidenced by renewed cracking in the pavement of 75t Place West. Readings from an inclinometer casing installed in the street right- of-way in front of the adjacent property to the north, shown in figure 9A and 9B indicate that the slide is about 18 feet deep at the western side of 75th Place West. As part of the current study, HWA installed an inclinometer casing in BH-1 so that any earth movements at that location can be detected. The results of measurements in this casing indicate that the existing slide terminates at the toe of the slope on the east side of the park and does not involve most of the park site. 1 Because the existing landslide is confined to the north end of the slope on the eastern side of the park, the proposed park development can proceed without stabilizing the slide, providing the City is willing to accept that portions of the park, as well as the roadway and the utilities within its right-of-way, will continue to be affected by the sliding. Current plans for park development include placing fill along the toe of the slope below the roadway, which will tend to increase the stability of the slide. In order to evaluate the stabilizing influence of such fill, HWA performed a series of computer -model stability analyses. An analysis was first performed to estimate the strength of existing soils on the hillside by assuming ' a factor of safety of 1.0 for the existing slope. The results of this analysis are shown on Figure 11. Soil strength parameters developed from this model were then used to determine the changes in factor of safety for various buttress fill configurations. The results of one such analysis is shown on Figure 12. These analyses indicated that the planned 5-foot high buttressing fill along the toe of the slope will increase the stability of the slope by about 17 percent. These analyses also indicated that: ' The buttressing fill should extend to the top of the slope (as shown on Figure 12) to prevent failure planes with lower factors of safety from day -lighting higher up on the slope above the buttress. ■ Buttress fills thicker than 5 feet will produce correspondingly higher factors of safety. 200617121 Revised Geotechnical Report.doc 8 HWA GeoSciences Inc. J May 30, 2008 HWA Project No. 2006-171-21 ■ Because the proposed fill extends only part way across the toe of the slide, the actual increase in factor of safety from a 5-foot fill will be less than 17 percent. To maximize the increase in stability, we suggest placing as much fill as the park configuration will allow, including placement of fill on the adjacent property to the north. We understand that for the purpose of park space utilization, it is desirable to retain the buttressing fill with a retaining structure. To further increase the stability of the slope we recommend that this retaining structure be founded on drilled piers which extend vertically downward (approximately 10 feet) to extend through the soft clay into the underlying medium stiff clay. These piles, consisting of 24-inch diameter concrete cylinders on 6- to 8-foot centers will provide additional shearing resistance across potential slide planes in the soft clay. The result will be a significant increase in the stability of the slope. A reinforced concrete footing can be cast along the tops of the piers and the retaining structure can be constructed of Keystone -type blocks. We recommend that geogrid reinforcement be included in the buttress fill in accordance with Section 3.2. 3.5.2 Park Drainage We believe the installation of a trench subdrain across the park property is necessary to remove excessive moisture for park development and enhance the stability of the lower portion of the park. We recommend the construction of a trench subdrain across the park. The subdrain would consist of a 4 to 5-foot-deep trench extending roughly north -south along the toe of the eastern slope and then turning westward near the north property line to daylight at the western edge of the park. Finger drains extending up -slope from the trench drain, spaced about 25 feet apart will further increase drainage. The approximate location of the proposed trench drain is shown on Figure 6. A 6-inch diameter slotted plastic pipe would be placed in the bottom of the trench and the trench would be backfilled with 1'/4-inch-minus crushed rock. The trench subdrain would intercept and remove ground water seepage from the site. 3.5.3 Foundation Design Structures in the park may be supported on spread footings providing they can tolerate some settlement. The soils are capable of supporting structures at allowable bearing pressures up to 1,500 psf; however, some settlement is likely due to the loose, soft and variable nature of the soils. Structures that can not tolerate 2 inches of total and 1 inch of differential settlement should be supported on small diameter pipe piles as described in Section 3.3. Column footings should have a minimum width of 24 inches and wall footings should have a minimum width of 18 inches. Footings should bear at least 18 inches below the lowest adjacent finished grade. 200617121 Revised Geotechnical Report.doc 9 HWA GeoSciences Inc. ' May 30 2008 HWA Project No. 2006-171-21 �J 3.5.4 Park Pavement ' Any pavements within the park that will carry vehicular traffic should be constructed as accordance with the recommendations in Section 3.4. We recommend that pavements for 1 walkways and trails consist of 6 inches of 1'/4-inch minus crushed rock overlain by 1'/Z inches of asphalt.

INTRODUCTION This report presents geotechnical recommendations for design and construction of the proposed walkway improvements to 76d' Avenue West and 75`" Place West in Edmonds, Washington. The purpose of this work was to assess geotechnical conditions along the project alignment and provide recommendations for design and construction of the proposed improvements. 1.1 Site and Project Description The project is located in the Meadowdale area of Edmonds, which is located along the shoreline of Puget Sound north of the city. The area is indicated on the Vicinity Map, Figure 1. The project will include construction of a walkway along 70 Avenue West and 751h Place West extending from Meadowdale Beach Road north to North Meadowdale Road, with some additional improvements north to the King County Park. The project will include development of a park at the north-west comer of 75 h Place West and 162nd Street SW. Three conceptual designs for the proposed improvements were developed during I preliminary studies. We understand Concept 1 was selected for fmal design and construction. Under the selected concept, the new sidewalk will be located along the east (upslope) side of the roadway from Meadowdale Beach Road north to 162nd Street SW. Cuts into the hillside will be required for the new sidewalk in much of this area. The cuts will be typically 3 to 4 feet in height but will be up to 12 feet high in some areas. From 162nd Street SW north to North Meadowdale Road the new walkway will be located on the western side of the road. Since placing fill along the top of the slope could reduce the stability of the slope and is to be avoided, the new sidewalk will be supported ' on small diameter pipe piles where there is insufficient existing flat area. North of North Meadowdale Road two pull-outs will be constructed on the east side of the road for vehicle parking, and one 130-foot-long section of pile -supported walkway is planned on the west side of the road. Development of the proposed park will include regrading the site and construction of a driveway, walkways, lawn and play areas. We understand an interpretive overlook is planned adjacent to 75d' Place West. A plan of the proposed park is presented on Figure 6. 1 I� I F 1 November16, 2007 HWA Project No. 2006-171-21 2. EXPLORATIONS AND GEOLOGIC CONDITIONS 2.1 Subsurface Explorations Subsurface information for the project was obtained by advancing three hollow stem auger borings designated BH-1 through BH-3; nine hand borings designated HH-1 through HH-9; and three DCP soundings performed in concert with hand borings HH-7 HH-8 and HH-9. Boring 1311-1 was conducted by Davies Drilling Inc. using a track mounted CME-75 drill rig with a 3.25 inch OD hollow stem auger. Borings BH-2 and BH-3 were drilled by Environmental Drilling using a truck mounted B-61 drill rig with an 8 inch OD hollow stem auger. Boring BH-1 is located in the northeast section of the proposed new park. Borings BH-2 and BH-3 are located along the proposed sidewalk alignment where a new solider pile wall will be installed on the east side of 76"' Avenue West and 75d' Place West. Hand holes HH-1 through HH-6 are located along the east side of 76th Avenue West and 75 h Place West along the alignment of the proposed sidewalk. Hand holes HH-7 through HH-9 along with their associated DCP soundings are located along the west side of 75t' Place west between 162nd Street West and North Meadowdale beach road. Borings were advanced either at the edge the City`right of way, or in the middle of the right travel lane, as shown in Figures 2-4. A 2-inch diameter ground water monitoring well was installed in BH-2 with screen from a depth of 15 to 25 feet and a silica sand filter from a depth of 12 to 30 feet. A slope inclinometer casing was installed in BH-1 after the completion of the boring. The casing was installed to a depth of 35 feet below the ground surface and was incased in cement grout. A baseline reading for future measurements was taken on October 24a' 2007. Borings were located using a site map provided by Gray & Osborne inc. by measuring ' from existing structures shown on the base map provided. A legend of the terms and symbols used on the boring logs is presented in Figure A-1. Summary boring logs are presented in Figures A-2 through A-13. Standard Penetration tests were performed at 2.5-foot or 5-foot intervals in all three borings. The Standard Penetration test consists of driving a 2-inch O.D. split -spoon sampler a distance of 18 inches into the bottom of the borehole with a 140-pound hammer falling 30 inches. The number of blows required to drive the sampler each of three 6-inch increments was recorded, and number of blows required to cause the last 12 inches of penetration was termed the Standard Penetration Desistance (N-value). This value is an indicator of the relative density or consistency of the soils. Whenever 50 or more blows were required to cause 6 inches of penetration, driving was stopped and the number of blows and corresponding penetration were recorded. Samples recovered from the split spoon sampler were disturbed but were representative of the soils encountered. ' Final Geotechnical Report 2 HWA GeoSciences Inc. �I I I Novemberl6, 2007 HWA Project No. 2006-171-21 An HWA geologist monitored the drilling and logged the borings. Soil samples were obtained from the borings at intervals of 2.5 to 5.0 feet, classified in the field, and representative portions were placed in plastic bags. These soil samples were taken to our Lynnwood, Washington, laboratory for further examination and testing. Pertinent information including soil sample depths, stratigraphy, soil engineering characteristics, and ground water occurrence were recorded on the exploration logs. The stratigraphic contacts shown on the individual boring logs represent the approximate boundaries between soil types; actual transitions may be more gradual. The soil and ground water conditions depicted are only for the specific date and locations reported and, therefore, are not necessarily representative of other locations and times. 2.2 General Geologic Conditions Geologic information for the project site was obtained from the published geologic map for the area; Booth, D. B., Cox, B. F., Troost, K. G., and Shimel, S. A., 2004, Composite geologic map of the Sno-King area: University of Washington, Seattle Area Geologic Mapping Project, scale 1:24,000. This map indicates that the surficial geology of the area consists of Pre -Fraser terrestrial deposits, overlain by Vashon-stade advance outwash, a unit of mostly clean sand with some gravel, overlain by Vashon-stade glacial till a non -stratified and non -sorted mixture of clay, silt, sand, and gravel. The terrestrial deposits reside mainly in the northern portion of the sidewalk alignment while the till and advance deposits are seen in the southern portion of the alignment. The area is also overlain by landslide colluvium deposited by the ancient Meadowdale slide. The landslide deposits occur throughout most of the site and are surficial above the glacial and pre -glacial terrestrial deposits. 2.3 Landslide History The majority of the project alignment lies within the North Edmonds Earth Subsidence and Landslide Hazard Area, which is described in detail in a report titled "Landslide Hazards Investigation, Meadowdale Area, Edmonds, Washington" prepared by Roger Lowe Associates in 1979. According to the Roger Lowe Associates report, this area of Meadowdale experienced large-scale ground movement between two and three thousand years ago. This slide was approximately 3,200 feet long and up to 650 feet wide. The head scarp is easily distinguishable above 751h Place West. The cause of this large-scale earth movement is inferred to be progressive shoreline erosion by wave action; the waves eroded the toe of the slope, which over -steepened it and eventually led to land sliding. Construction of the Great Northern Railroad, which is currently owned by Burlington Northern Santa Fe, along the beach, has halted the shoreline erosion process since it armors the toe of the slope from wave erosion. 11 Final Geotechnical Report 3 HWA GeoSciences Inc. Novemberl6 2007 HWA Project No. 2006-171-21 1 No large-scale earth movements have been recorded for this area in modern times. However, subsequent to the ancient slide, the mass of soil within the body of the slide has experienced numerous small-scale adjustments. This type of post -slide adjustment is common and typically occurs in the form of shallow earth slumps. More recently, sliding occurred in the area in January 1997, after heavy snowfall was followed immediately by several inches of rain. Sliding occurred at several locations on the eastern side of 75`t' Place West and debris from one slide flowed across the street and came to rest on the western side the road. Landslides occurred throughout the Puget ' Sound Region at that time and are described in more detail in the paper by Gerstel et al. titled "Puget Sound Bluffs: The Where, Why, and When of Landslides Following the ' Holiday 1996/97 Storms" (in Washington Geology, vol. 25, no. 1, March 1997). The study YRogerb Ro Lowe Associates also indicates that the stabilityof the Meadowdale area is highly sensitive to groundwater levels. Improvements to local site drainage, including the installation of sewers and storm drains, have had a positive impact on the stability of the area. 2.4 Subsurface Conditions Based on the results of our exploration program, the soils underlying the project area were observed to consist of Pre -Fraser terrestrial deposits overlain by colluvial depoits and small localized quantities of fill. This observation is consistent with the soils unit ' mapped in the area by Booth ET. Al., by Roger Lowe Associates, and as encountered during previous drilling undertaken by HWA to evaluate the subsurface conditions for other projects in this area in the past. (HWA, 2003). Following are descriptions of the soil deposits encountered in our explorations in the order of stratigraphic (depth) sequence by which they were deposited or placed, with the youngest unit described first. Detailed descriptions of the soils are presented in the exploration logs in Appendix A. A legend of the terms and symbols used on the boring logs is presented in Figure A-1. Summary boring logs are presented in Figures A-2 ' through A-13. Fill — Fill, consisting of loose to medium dense silty sand to sandy silt was identified in the locations of BH-1, BH-3, HH-1 and HH-7 through HH-9, and ranged from 1.25 to 7 ' feet thick. The fill was usually identified adjacent to the road, most likely from the grading of the roadway during the initial construction. 1 Topsoil — Topsoil consisting of light brown to dark brow, silty sand with gravel was identified in HH-1 through HH-5. In all of the hand holes the topsoil consisted of loose to medium dense surficial material with abundant roots and rootlets being present. ' Depths ranged from 0.5 to 2.0 feet in depth. ' Final Geotechnical Report 4 HWA GeoSciences Inc. t Novemberl6, 2007 HWA Project No. 2006-171-21 Colluvium — Colluvium was encountered in all of the borings and in hand holes HH-2, HH-6 and HH-9. It generally consisted of very soft to medium stiff clays and silts with interspersed pieces of colluvial clays and silts, with seams of sand. The majority of the colluvium has experienced some oxidation mottling, and the seams of sand tended to be wetter than the surrounding fine grained material. ' Colluvial Blocks — Colluvial blocks were encountered in Borings BH-2 and 13H-3 under the softer colluvial material that overlies it. In the case of these explorations colluvial blocks refers to disturbed native soils that are denser then the overlying material, but still ' exhibit some variability in density and an irregularity in the soil that does not correspond with native undisturbed glacial and pre -glacial terrestrial deposits. For example in BH-3 loose poorly graded sand was encountered from 18 to 26 feet between very stiff clay and ' a hard laminated silt. It is not known when or how these materials were mobilized in the past, but they do exhibit some signs of disturbance. Recessional Outwash — Loose to medium dense glacial outwash consisting of light brown silty sand with gravel to gravelly sand with silt was identified in HH-3 through HH-5. The recessional outwash was encountered on the uphill (east) side of the sidewalk alignment in the area where a slope cut will occur for the new sidewalk. At the locations ' of TP-1 and TP-16, thin layers of silty sand were encountered from 0.5 to 1.0 foot thick, which appeared to consist of recessional outwash. These soils were loose to medium ' dense and directly overlie the glacial till. 2.5 Ground Water Conditions ' Ground water seepage was encountered in borings BH-1 and 13H-2 and HH-2. We expect, however, that actual ground water depths will vary depending on the season, ' variation in local subsurface conditions, and other factors. The project alignment is near the toe of the hillside, which is a ground water discharge area. Consequently, springs and seeps occur at numerous locations along the alignment where groundwater emerges from the ground. ' 2.6 Laboratory Testing Representative soil samples obtained from the subsurface explorations were returned to the HWA laboratory for further examination and testing. Laboratory tests, as described below, were conducted on selected soil samples to characterize relevant engineering properties of the on -site soils. ' Moisture Content of Soil: The natural moisture content of all soil samples (percent by dry mass) was determined in general accordance with ASTM D 2216. The results are shown at the sampled intervals on the test pit logs in Appendix A. I I ,' Final Geotechnical Report 5 HWA GeoSciences Inc. ' Novemberl6, 2007 HWA Project No. 2006-171-21 ' Particle Size Analysis of Soils: Selected samples were tested to determine the particle size distribution of material in general accordance with ASTM D 422. The results are summarized on Figure B-1, Appendix B, which also provides information regarding the classification of the samples and the moisture content at the time of testing. Liquid Limit, Plastic Limit, and Plasticity Index of Soils (Atterberg Limits): Selected samples were tested using method ASTM D 4318, multi -point method. The results are reported on the attached Liquid Limit, Plastic Limit, and Plasticity Index reports, Figure B-2. 3. RECOMMENDATIONS ' 3.1 GENERAL Construction of a walkway along 76t' Avenue West and 75t' Place West will require ' excavation into the toe of the slope on the up -slope (eastern) side of the roadway in some areas, and placement of fill or a pile supported partially -elevated walkway on the downslope side of the road. Because placement of fill on the downslope side of the road would add to the weight of a potential landslide, reducing the stability of the slope, we recommend that filling be avoided to the extent possible. As a result, we recommend that walkways and walkway approach structures on the downslope side of the road be pile - supported wherever there is insufficient existing flat terrain. Development of the propose park will include regrading the site and construction of a driveway, walkways, lawn and play areas. We understand an interpretive overlook is planned adjacent to 75a' Place West. Because of the relatively high ground water level ' and the presence of an existing landslide on the property, we recommend the installation of a deep trench subdrain across the park. More detailed recommendations for park design are presented in Section 3.5. 3.2 EARTH RETAINING STRUCTURES Cuts along much of the eastern side of the alignment will be 3 to 4 feet tall. In our opinion, the most cost-effective way of retaining these shallow cuts would be with modular block walls such as Keystone blocks, or with rockeries. Block walls up to about 4 feet high (twice the depth of the block) may be made by stacking blocks without need for geogrid reinforcing. Block walls higher than twice the block depth should include geogrid reinforcing which extends back from the, face of the wall a horizontal distance ' equal to at least 0.7 times the free-standing wall height. Geogrid reinforcing should be placed between every second layer of blocks. We recommend the use of Tensar BX1200 geogrid, or equivalent, wherever geogrid reinforcing is needed. 1 Final Geotechnical Report 6 HWA GeoSciences Inc. ' Novemberl6, 2007 HWA Project No. 2006-171-21 ' Because of the horizontal space required for block walls, it may be desirable to use soldier pile and lagging walls where the retained height of the cut exceeds about 4 feet. Soldier pile and lagging walls would consist of 4-inch or larger H piles set in concrete in pre -drilled holes. Lagging consisting of treated timber or precast concrete panels would be placed between the soldier piles. The size of the H-pile section would depend on the height of the wall and the horizontal spacing of the piles. Soldier piles should be designed to resist an equivalent fluid pressure equal to 55 pounds per cubic foot (pcf) ■ plus one pcf for each degree of upward inclination of the backslope. We recommend the soldier pile walls be tall enough that the backslope inclination does not exceed 2H to 1 V. Fill could be placed behind the soldier pile walls as necessary to flatten the slope. Soldier piles which are set into concrete in predrilled holes should penetrate below finished grade at least 1.5 times the wall's free-standing height. We do not recommend driving soldier piles because: 1) driving and maintaining pile alignment may be difficult in dense gravelly soils, 2) vibrations from pile driving can cause landslides, and 3) a concrete -filled hole provides better lateral resistance than a driven pile. Piles which are driven in place would need to extend to a depth equal to twice their free-standing height. ' Backfill behind the lagging should consist of 11/4-inch minus crushed rock. Soldier pile and lagging walls constructed as recommended above are typically permeable and will ' allow the passage of moderate amounts of seepage. Where significant volumes of water are expected, such as at existing springs, a slotted drain pipe and crushed rock backfill should be placed to intercept the flow and convey it through the wall to the storm drain system. 3.3 PILE SUPPORTED WALKWAYS Where pile support of walkways and approach structures is required, we recommend the use of 2-inch diameter extra -strong steel pipe. When driven to less than 1 inch of ' penetration in 1 minute of driving with a 90 psi jackhammer, each pile should be capable of supporting 2 tons of vertical load (allowable capacity) with an adequate factor of safety. Pile installation can actually be accomplished with a backhoe-mounted compactor ' (hoepac), but testing to verify capacity should be done with a jackhammer. Piles will develop their bearing in native soils below any fill, and pile lengths will vary considerably. Pile lengths could average 20 to 25 feet. ' 3.4 PAVEMENTS Where new street pavement is required, the pavement subgrade should be proof -rolled to verify that it is dense and unyielding. Any soft or spongy material should be replaced with 11/4-inch-minus crushed rock. The pavement section should consist of at least 6 ' inches of crushed rock (CSBC) and 3 inches of asphalt. 1 Final Geotechnical Report 7 HWA GeoSciences Inc. Novemberl6, 2007 HWA Project No. 2006-171-21 3.5 PARK DESIGN A plan showing the park property with existing ground surface contours and the location ' of boring BH-1 is presented on Figure 5. A cross section through the park property showing BH-1, the previous boring HWA-3, and the assumed failure plane of the existing landslide is shown in Figure 7. The proposed layout of park facilities is shown on Figure 6. 3.5.1 Stability As indicated on Figure 5, the park property slopes downward from 75 h Place West about 2H to 1 V for approximately 20 vertical feet. The site then slopes gradually to 75th Avenue West. Our previous studies indicate that a landslide exists on the north end of the park property and the adjacent property to the north. The slide is still moving as evidenced by renewed cracking in the pavement of 75a' Place West. Readings from an ' inclinometer casing installed in the street right-of-way in front of the adjacent property to the north, shown in figure 9A and 9B indicate that the slide is about 18 feet deep at the western side of 75fl' Place West. As part of the current study, HWA installed an inclinometer casing in BH-1 so that any earth movements at that location can be detected. Based on our previous studies and the existing site geometry, it appears likely that the existing slide terminates at the toe of the slope on the east side of the park and does not involve most of the park site. The results of future measurements in the two inclinometer casings will confirm or deny that assumption. Assuming that the existing landslide is confined to the north end of the slope on the eastern side of the park, the proposed park development can proceed without stabilizing the slide, providing the City is willing to accept that portions of the park as well as the roadway and the utilities within its right-of-way will continue to be affected by the sliding. Current plans for park development include placing fill along the toe of the slope below the roadway, which will tend to increase the stability of the slide but may not be sufficient to prevent future movement. A definitive stabilization design will require additional measurements in the two slope indicator casings over the course of the coming winter to determine the location of the slide plane and performing stability analyses to develop stabilization measures. That additional analysis is not within the present scope of work; however, we recommend that this additional analysis be performed and the results incorporated into the park design. 3.5.2 Park Drainage We believe the installation of a trench subdrain across the park property is necessary to remove excessive moisture for park development and maintain stability of the lower portion of the park; however, it may or may not be effective in stabilizing the existing landslide. Final Geotechnical Report 8 HWA GeoSciences Inc. ' Novemberl6, 2007 HWA Project No. 2006-171-21 1 ' We recommend the construction of a trench subdrain across the park. The subdrain would consist of an 8 to 10-foot-deep trench extending roughly north -south along the toe of the eastern slope and then turning westward near the north property line to daylight at ' the western edge of the park. The approximate location of the proposed trench drain is shown on Figure 6. A 6-inch diameter slotted plastic pipe would be placed in the bottom of the trench and the trench would be backfilled with 1'/4-inch-minus crushed rock. The trench subdrain would intercept and remove ground water seepage from the site and would serve as a shear key to reduce the potential for future sliding. ' 3.5.3 Foundation Design Structures in the park may be supported on spread footings providing they can tolerate ' some settlement. The soils are capable of supporting structures at allowable bearing pressures up to 1,500 psf; however, some settlement is likely due to the loose, soft and ' variable nature of the soils. Structures that can not tolerate 2 inches of total and 1 inch of differential settlement should be supported on small diameter pipe piles as described in Section 3.3. Column footings should have a minimum width of 24 inches and wall footings should have a minimum width of 18 inches. Footings should bear at least 18 inches below the lowest adjacent finished grade. ' 3.5.4 Park Pavement Any pavements within the park that will carry vehicular traffic should be constructed as accordance with the recommendations in Section 3.4. We recommend that pavements for walkways and trails consist of 6 inches of 1'/4-inch minus crushed rock overlain by 1'/2 inches of asphalt. 4.0 CONDITIONS AND LIMITATIONS We have prepared this report for Gray & Osborne and the City of Edmonds for use on this project.
