Bold items are excerpts from that letter, identically enumerated, with our response following. Technical Information Report Section N Drainage Improvements 1. Exemption #1 of Core Requirement 3 was not Intended to allow water to go un- detained when detention could be provided. Please explore other alternatives to detain the runoff from I Avenue S and the west end of the driveways for all three lots, or over -detain in other areas. We note that KCSWM text regarding flow control exemptions and Appendix C-3 implies that the absence of flow control facilities for this type of project is justified by the use of the soils natural capacity to absorb water. The design disperses and infiltrates runoff to the maximum extent passible under the code, by using roof infiltration, modular grid pavement, and driveway dispersal trenches. We have explored other options including formal infiltration trenches (sills are not adequate ... see item 2 below). Also, Code requires a separation of 28' from driveway dispersal trenches and downhill property lines/structure, thereby limiting the dispersal trench from intercepting drainage below elevation 448 and hence, making the bypass necessary. The small site Appendix C-23 does allow for perforated storm ine connections, but limits their applications. Perforation of the proposed storm drain fine in 18'h Ave S. frontage could possibly serve to re -infiltrate some portion of runoff and could presumably be justified since the storm drain is replacing an existing ditch where re -infiltration occurs naturally. 2. The soils report Indicated a percolation rate of 15.08 Inches per hour, which Is suitable far infittrating runoff from all impervious surfaces, including driveway runoff, per KCSWDM,secdan C.2.3. This is contrary to you statement in the O paragraph of this section. The geotechnical report indicates no groundwater seepage, and states that the static groundwater level is well below the site. Since only one foot is needed between the trench bottom and the groundwater level, lnfiltration may be an alternative for providing additional detention of the driveway runoff. Under the section labeled "Subsurface Conditions° in the Geotech report, the stratigraphy is described as "undisturbed semi -cemented glacial till... overlain by up to 3 feet of weathered till.... No groundwater seepage was observed ... pgEgc ed groundwater conditions should be exRected during periods of extended wet weather." (Underlined for emphasis). Appendix C, section C2.3.1, bullet 2 states that infifiration systems on lots less than 22,000 square feet (site lots are 7.200 sf) must be in outwash sands or cobbles. The geotech report indicates that the site till soils do not meet this requirement. Our concern with installing infiltration systems is that, given the high groundwater possibility and nature of the native soils, such a system may not pass performance testing and ultimately may fail. The design provides for dispersal trenches that will allow re -infiltration through the surface soils without the impact of additional design constraints associated with formal infiltration systems. Section V Conveyance Systems Analysis and Design 3.Please provide actual calculations to show that the conveyance system in 18"' Avenue S is capable of conveying the 25-year flow. Since development or a City project could replace the pipe upstream at any time, upstream conveyance capacity is irrelevant. The project must be designed to most current standards. An analysis has been included in the TIR, and it confirms the adequacy of the prior design. 4. Bond Quantifies Worksheet Please use the bond quantities worksheet provided in the City of Federal Way Development Standards Manual. The City's bond form has been completed and substituted in the TIR for the K.C. bond form. Engineering Plans General: 5. Please provide the eity's standard signature block, enclosed, on each sheet These have been provided. 6. The expiration date for engineer's seal is missing on some pages. The seals have been revised as requested. 7. Please provide a table of convents. The Sheet Index was shown prior on Sheet C-1. It is a table of contents and lists all plan sheets. 8. Provide at least one sheet showing all boundary survey information that has been stamped by a professional land surveyor. A signed copy of the survey is included with the re -submittal package, as requested. Sheet 7 -- Site Plan ,,.... , IN Lrg. Please provide a street tree on 181 Avenue S. Approved trees for 4' wide planter strips are shown on the enclosed list: A street tree is shown on the site plan and stationed on the grading and road plans and detailed on the detail plans. 0. Please label the street centerline and the existing edge of asphalt: Centerline ROW and Edge of Pavement labels have been added to the Site Plan and the GradinglRoad Plans. Note that the painted centerline is different from the centerline of ROW. 11. Please revise the "Governing Agencies" section to include the Public Works inspection phone number, 253-661-4131, Ann Dower as the review engineer, and my phone number, 235461-4126. The changes were made as requested. Sheet 2 — Erosion Control Plan 12. Provide erosion control for the downstream ditch. Excelsior mat ditch protection has been called out in plan view and detailed. Sheet 3 Grading and Drainage Plan 13. Include the project benchmark and description, and the vertical datum identification on each sheet that includes elevations. t The project benchmark and datum descriptions have been included on the Site Plan, Grading Plan and Road Improvement Plan Sheet 4 — I e Ave. S Road Plan & Profile 14.Please provide a cross-section for 18"' Avenue S similar to the one enclosed. A cross section has been added for 1 e Ave S. on the Sheet C-4 road plans. 15.The survey and stationing must be tied to an existing monument Please showllocate the monument Sheet Cam, road plans, has been expanded to show the reference monument and relative stationing in the upper right hand portion of the drawing. 16. Please provide a detail of the rip rap outlet The detail has been added to sheet C-7, bottom right. 17. All lettering must be at least 10-point font Lettering size has been changed consistent with this request. 18. Please show the lane widths, eenterline4o-curb distance, and any required striping. Mr In The requested data has been added to the site plan, C-1, the road plan and cross section C-4 as appropriate. 19.Please show a cap on the upstream end of the conveyance pipe, show the ditch flow line, and show where the downstream end will daylight on both the profile and plan views. As discussed, the cap is unnecessary since the upstream ditch flows into the proposed pipe. Ditch flow lines and daylight data have been added to the profile and plan views on C-4. 20.Provide a centerline offset distance for catch basin #1. This has been done as requested, both in profile and plan view. 21.Please review the height and location of the overhead power lines with that of the new streetlight Is there a conflict? There is a conflict. Per our discussion and your 8-28-03 e-mail, we have revised the C-4 callouts and C-6 (H.C. note #8) to specify that the iuminaire should be mounted on the ekisting power pole in the vicinity of the driveway. 22.Please indicate the material to be used forthe storm pipe within the public right-of-- way. Acceptable pipe materials are listed in the City of Federal Way Development Standards Manual. LOPE has been specified in the profile view of C-4. 23.Note that a vaned grate is required for the catch basin in the public right -of --way. A vaned grate has been added to the cahoot (C-4) and detailed (C-5). 24.Streetlight information must include the power source, any necessary conduit runs, j-box location, and offset information for the pole and j-box. The detail must include the arm length, keeping the luminaire 2' beyond the face of the curb. The pole must be located behind the sidewalk, within the public right-of-way. We have made application with Puget Power for the new luminaire, to be mounted on the existing pole. (See item 21 above). Sheet 5, Notes and Details 25.The font on all of these details is too small. An example of the correct size, 1 0-point font, is attached to the redline. Further comments may apply once the details are legible. Font sizes have been corrected as requested 26.131ease provide a detail for the Grasscrete installation. A detail has been added to sheet C-7, and reference catalog cut information is included in our re - submittal package. A number of manufacturers make modular grid paving products capable of supporting the fire truck loads. 27.Please revise the 18"' Avenue S paving section to show 0.25' Class B asphalt; 0.17' CSTC, and 0.42' CSBC. The section was deleted and the requested paving depths were added to the new section on C-4. 28.Make the detail for the private road accurate fbr this project. For example, the plan view does not show the private road graded to drain to a catch basin on the side of the road. The catch basin is located in the middle of the shared driveway, in a V section, as shown. We are including a copy of e-mail from Sarady Long after he reviewed this detail and indicating Traffic Dept - acceptance of the section. Minor revisions were made to the detail, as we felt appropriate. 29.12lease add details for sidewalk (3-12), sheet tree planting (3-29), Are department access (3-46), street names sign (3.49), post (3.51), and installation (3.50). The details were added, except for street sign related details, which were omitted per direction on your e-mail of 8-18.

Per Road Crass section Y, .of the City's development standards, 5 foot sidewalks are normally required on both sides. We request that the City waive the requirement for a 5' sidewalk on the south side of the proposed road, since this sidewalk provides no access to the proposed short plat lots (which access from the northerly sidewalk), nor to the abutting property since it is in an easement. The abutting property is currently configured as a church, with no current access to the proposed street. Church access is currently achieved thru direct access to 18t' Ave. South. As such, the southerly sidewalk would not be advantageous to the neighborhood or the City as a whole. Additionally, if the sidewalk were required, the proposed lots would diminish in depth from 54 feet to 49 feet, and this dimension imposes constraints on the ability to site a home.

PROJECT OVERVIEW The Proposed Development consists of a 3 lot short plat on approximately 0.86 acres. Existing Zoning is RS 7200. The site is located at 29830--18a'Ave South, in Federal Way, Washington. The proposed residential development requires Frontage Road Improvements, construction ofan on site roadway access, fire truck turn around gravel driveways and drainage improvements in compliance with the City storm drainage Code. Site design criteria are based on the 1998 King County Storm Drainage Manual, as currently adopted by the City of Federal Way. II. PRELLVMARY CONDITIONS SUMMARY The property is entirely vacant pastureland. Existing Grades slope down from the east and west edges of the property fronting on 18'' Ave South. Drainage then travels to the south in roadside swales and culverts for 300 feet where it is intercepted by underground storm drains at the Pacific Highway intersection with 18t' Ave. South. These drains convey flows northerly for the extent of 1.4 mile. Site slopes vary between 2 and 40 percent. The steeper slopes lie at the easterly extent of the site and are addressed in the Geotechnicai Report prepared by Geotechnical Testing Laboratory, Olympia Wa. May 7, 2001. Site soils are classified as Alderwood Series per SCS mapping, Existing soils consist of gravely sandy loam till, firm to a depth of approximately 42 inches, with cemented glacial till underneath. The soil borings indicated dampness, but no obvious shallow groundwater levels. There are no indications of closed depressions on the property. 18"' Ave. South fronts along the west boundary of the property. Road drainage is currently collected in a roadside ditch and culvert system and is conveyed southerly. For short plat approval, the City requires that the frontage be improved to provide 40' paved width, curb, gutter, 4' planter strip and 5' sidewalk. M. OFF -SITE ANALYSIS (LEVEL ONE DOWNSTREAM DRAINAGE ANALYSIS) Upstream from the easterly boundary of the project, there are two existing single-family residences. These homes are accessed through driveways onto 20'' Ave. South, 2& Ave South is serviced by an existing storm system. Substantial landscaped yards buffer these homes from the project. Since there was no evidence of surface flows or prior erosion on the easterly slope of the project, it is evident that precipitation on the upstream areas predominantly percolates into the underlying soils. Existing Grades slope down from the east to the west edge of the Property fronting on 181h Ave South. Drainage then travels to the south in roadside ditches and culverts for 300 feet where it is intercepted by underground storm drains at the Pacific Highway intersection with 181h Ave. South. These drains convey flows northerly in 12 inch to 24 inch diameter storm pipes for the extent of 1.4 mile to the near the intersection of Redondo Way South and South Dash Point Road where it enters Redondo Creek. Mapping is included herewith defining the study area for a distance of 1 mile downstream along the alignment of Redondo Way South. City GIS topographic mapping is also included herein. A review of the City's Comprehensive Plan shows that the study area lies within the Star Lake sub - basin of the Lower Puget Sound basin. Drainage along the Redondo Way South portions of the basin is predominantly contained in the Star Lake outlet stream. Portions of the study area are susceptible to groundwater contamination and geologic hazards as defined in the Comp Plan mapping. Visual reconnaissance of the downstream system revealed no indications of scour, flooding, plugged culverts, overtopping or general drainage problems. Neither the current property owner nor City Staff have reported to us any drainage complaints or problems for the downstream area. An offsite Analysis Drainage System Table (98 KCSWM ref 8-B) is included summarizing findings. LU 46 Z Z C .Q! Yi mm 1 IV. PROPOSED DRAINAGED E%UROVEMENTS Frontage Improvements are required to widen I e Ave South to a full 40 feet of pavement with curb, gutter, 4' planter strip and 5' sidewalk. Overhead power along the frontage need not be under grounded since City Code (Fed Way Dev. Stds. Pg 1-6) allows exceptions where less than 500 feet of frontage is contemplated or where less than 3 spans are relocated (in this case, none are). The existing ditch flows upstream of the improvement will be conveyed in new storm drains to a discharge point in the existing ditch. The proposed common driveway for lot 2 and 3 is designed in compliance with the King County Road Standards section 3.01 C. 3.a. and City of Federal Way Development Standards section 22- 1496 and consists of a 20 foot wide surface. The site lies in a level 1 flow control area. Computations were performed to determine the predeveloped (0.125 cfs) and developed (0.228)100 year flow rates using the KCRTS methodology using 1 hour time steps in compliance with KCSWM table 3.2, pg 3-10. While roof downspout infiltration systems are proposed to mitigate for the roof areas, such that roof areas could technically be regarded as "grassed till" instead of impervious for purposes of sizing flow control facilities, the credits do not apply when determining eligibility for exemptions from Core Requirement #3(per KCSWM Pg. 1-36). Consequently, proposed roofs are included in the model to determine the 100- year developed flows. Since the increase in the 100 year runoff for the developed versus the predeveloped condition is less than 0.1 cfs and the project is a single family residential project, this site qualifies for exemption from core requirement #3, flow control, per exemption #3, pg 1=27 of the KCSWM. While flow control BMP's must be used for all impervious surfaces per KCSWM Appendix C, Small site Drainage Requirements, we have elected to use the formal roof downspout infiltration systems per KCSWM Pg. 5-5, due to the higher lot density of RS 7200 and the superiority compared with roof dispersal systems on smaller sites. Because Drive Way infiltration criteria of Appendix C requires native sand or cobble soils, the impervious site driveways and roads must be dispersed per appendix C, pg 17. Since 50 feet of vegetated flow path is not available, per KCSWM C.2.4.3, a driveway dispersion trench will be provided. Bullet 2 of the same reference, directs that figure 4.2.2.c (flow dispersal trench) be used, which in turn limits flows to 0.5 cfs per 50 foot of trench length. Since the total 100 yr peak developed flows are less than 0.23 cfs, a single trench would be adequate. Note that Page C-7 indicates that if site constraints make dispersion or infiltration infeasible, then the site may connect to storm drains with perforated tight lines per C2.5 , pg C-23. However, this provision does not appear necessary in this case, given the dispersal strategy. Portions of the new Lot 2/3 common access driveway and 18th Ave. South Improvements lie below the elevation of the proposed lowest dispersal trench (located on lot 1). This condition unavoidably creates a bypass area of 3,669 SF of new impervious roadway and sidewalk Exemption # 1 of Core Requirement 3, Pg 1-27, allows any threshold discharge area within a project of less than 5,000 s.f. to be exempt from flow control requirements. As an alternate, in order to comply with appendix C requirements as indicated above, the City might wish to require that this bypass flow be collected and conveyed in a perforated storm drain. Core requirement #8, water quality, KCSWM pg. 1-50 to 1-51, exemption #1 indicates that any proposed threshold discharge area within a project is exempt from water quality treatment requirements if it meets all of the following criteria: 1. less than 5000 s.f. of new PGIS The project creates 4,043 s.f of new PGIS 2. Less than 5,000 s.f of contiguous PGIS —of a redevelopment project The project is not a redevelopment project 3. Less than 1 acre of contiguous pgps will be added... Total PGPS created for the project consists of 8,146 s.f of modular grid pavement, which is less than 1 acre. While exemption # 4, KCSWM pg. 1-51 indicates that PGIS (pollution generating impervious surfaces) which are infiltrated into soils with infiltration rates slower than 9 inches per hour are exempt from water quality requirements, infiltration rates are too fast to take advantage of this particular exemption (site soils infiltrate at 16 inches per hour per geotechnical report).

CONVEYANCE SYSTEMS ANALYSIS AND DESIGN For the proposed public storm drain lying in 18"' Ave. S., the worst -case flow scenario is exemplified by the existing 12" conveyance culvert in Wb Ave South directly upstream. Per flow calculator, the capacity of this 12" culvert (n= 0.013, s=0.04) is 9 cfs with full flow velocity at 8 fps. This new storm drain pipe is of equivalent size, slope and capacity to the existing driveway culverts lying immediately upstream. The 25 year flow criteria which is required for conveyance design per the manual is met simply because the upstream pipes cannot convey greater flows to the new facility than the new facility is capable of handling. With regards to on -site conveyance, the total developed 100 year peak flow is 0.228 cfs. The 8" drain @ 1% slopes, n=0.013, can convey 0.5 cfs which exceeds requirements.

EROSION/SEDEMENTATION CONTROL DESIGN Erosion and sediment control measures for this project were prepared in compliance with the 1998 Ding County Surface Water Design Manual, Appendix D. This site falls under the small site erosion control requirements as specified in item D.3, page D-5 of Appendix D, since the proposed new impervious area is less than 10,000 square feet (8,907 s.f). Erosion Control BMP's shall consist of a small site rock construction entrance (10' x 25' nun.), minimal clearing limits as necessary to construct the access site access driveway and drainage features and silt fencing. Silt traps are not required for this site, although it is worthy to note that silt trap sizing based on the total developed site 2 yr flows (approx 0.03 cfs) yield a required trap area of 66 s. f. or 8' x 8' and the min. trap surface area size using detail requirements of 3.5' min depth and 3:1 max side slopes is 21' x 2l' or 441 s.f. This comparison demonstrates the relative insignificance of developed site runoff. X. BOND QUANTITIES WORKSHEET, DECLARATION OF COVENANT c d E r.

Frank Spears, P.E. March 7, 2001 GIAN SINGH 330 AVERY RD. E. CHEHALIS, WA 98532 GEOTECHNICAL TESTING LABORATORY Re: Geotechnical Report Lot 10, Block 2, Jeannette Sound View tracts Federal Way, WA INTRODUCTION This report summarizes the results of our geotechnical engineering services for the proposed building of two homes to be located on two separate building sites in Federal Way, WA. The location of the sites are shown relative to the surrounding area on the Vicinity Map, Figure 1. Our understanding of the project is based on our review of the preliminary site and grading plans provided by George Andrews and our site visits and explorations. We understand that a previous home was demolished to make place for new homes on the same location. The home sites will be accessed by a 30 foot road located to the south of the building sites. Storm water runoff from the building sites can be controlled by a silt fence placed on -site. The general layout of the sites are shown on the Site Map, Figure 2. The slope profile, Fig. 4, was taken across the center of the sites. We further understand that very little grading is required at the sites to reach design grades. In general, grading will consist of the removing of the present home debris and the compacting of the excavated area for the placement of the building foundations. The area of the home sites is relatively flat, and areas to the extreme east of the proposed new homes are between 15 and 30 percent. The portion of the site having slopes that are 30 percent are those areas where no construction or road work is anticipated. These 30 percent or less slopes are less than 15 feet in vertical height. The purpose of our services is to evaluate the surface and subsurface conditions at the site as a basis for providing geotechnical recommendations and design criteria for the project and to satisfy the requirements of the applicable Critical Areas Ordinance. Geotechnical Testing Lab has provided geologic and hydrogeologic services for the proposed home. Engineering recommendations and design criteria were provided by Frank Spears of Spears Engineering and Technical Services of Auburn, Washington. Specifically, our scope of services for this project will include the following: 1. Review the available geologic, hydrogeologic and geotechnical data for the site area. 2. Conduct a geologic reconnaissance of the site area. 3. Explore the shallow subsurface conditions arthe site by drilling test pits. 4. Evaluate the landslide and erosion hazards at the site per the applicable County/City Critical Areas Ordinance regulations. 10011 Blomberg Street SW, Olympia, WA 98512 Phone #: (206) 754-4612 Fax #: (206) 754-4848 3ba GEOTECHNICAL TESTING LABORATORY The Alderwood soils typically form in sandy glacial till areas and are described as having a slow permeability and a slight erosion hazard. These soils are typically classified as a "Group C" relative to surficial runoff. We observed no active erosion or slope disturbance in the site area during our reconnaissance. SUBSURFACE EXPLORATIONS Subsurface conditions at the site were evaluated by excavating 2 test pits with a hollow stem auger drill rig. The test borings extended to depths of 7 feet. The test pits were located in the field by our representative by pacing from existing site features such as street and property boundaries. The approximate locations of the test pits are indicated on the attached Site Plan, Figure 2. Our representative continuously monitored the test borings, maintained logs of the subsurface conditions, and obtained representative samples, as needed. The soils encountered were visually classified in accordance with ASTM D-2488.( See Fig. 3) The logs of the test pits are included as boring log sheets. SUBSURFACE CONDITIONS The subsurface conditions at the site were in general, undisturbed semi -cemented glacial till. The undisturbed till was encountered at depths of 3 feet below the existing ground. surface. The till was overlain by, up, to 3 feet of weathered till and an intermittent veneer of recessional outwash sand and gravel. The till thickness in the central portion of the site is approximately 4 feet deep. No groundwater seepage was observed in our borings. Based on the nature of the near surface soils, and weathered till over the undisturbed till, perched groundwater conditions should be expected during periods of extended wet weather. -- -� SLOPE STABILITY 7 Slopes as steep as 30% were observed in the areas where no buildings are anticipated. Since the slope is only 15 feet in vertical relief, we are only shading those areas greater than 29% and are not addressing them as geologic hazards. In general, the undisturbed native soils in the upland and steep slope. portions of the site consist of silty sands with variable amounts of gravel, cobbles and boulders, glacial till or hardpan. These soil materials are in a dense to very dense condition except where they have been disturbed by the activities of man and weathering activity. The near -surface recessional, weathered till and advance outwash are in a medium dense to dense condition, except at the ground surface. The surficial soils are generally in a loose to medium dense condition. These soils are generally stable, relative to deep-seated failure. No evidence of deep-seated landslide activity or significant erosion was observed at the site at the time of our site visit. Weathering, erosion, and the resulting surficial erosion, sloughing and shallow land sliding are natural processes that can affect steep slope areas. No evidence of local surficial erosion, raveling and sloughing was observed in the site area at the time of our site visits. Weathering typically occurs in the upper 2 to 3 feet and is generally the result of root penetration, wet/dry cycles, and freeze/thaw cycles. Erosion control is not a significant factor on this site. 10011 Blomberg Street SW, Olympia, WA 98512 Phone #: (206) 754-4612 Fax #: (206) 754-4848 UEOTECHNICAL TESTING LABORATORY 5. Provide geotechnical recommendations for site grading including site preparation, sub -grade preparation, fill placement criteria (including hillside grading), suitability of on -site soils for use as structural fill, temporary and permanent cut and fill slopes, drainage and erosion control measures. 6. Provide recommendations and design criteria for the foundation and floor slab support, including allowable bearing capacity, sub -grade modulus, lateral resistance values and estimates of settlement. 7. Provide recommendations and design criteria for drainage requirements, lateral design loads, and lateral resistance values. 8. Provide our opinion regarding the feasibility of the location/construction of the roof storm water retention facility. 9. Provide recommendations for sub -grade preparation. SITE CONDITIONS SURFACE CONDITIONS The proposed home sites are located in the Jeannette Sound View tracts in Federal Way, Washington. The proposed layout of the site is shown on the Site Plan, Figure 2. We conducted a reconnaissance of the site area and monitored the borings of two test holes and blow counts at the site. Elevations of the site area range from approximately 0 feet on the lower west end, or 18d, Ave., and approximately 50 feet higher in the east. The areas of 15 to 30 % are outside of the proposed building area. Site topography and slopes between 15 to 30 % are shown on the Site Plan, Fig. 2. We observed no evidence of erosion. Surficial sloughing and soil movement has occurred on the steeper portions of the site. No evidence of deep-seated slope instability was observed in the site area at the time of our site visit. The site is vegetated with alder trees and blackberry growth. No evidence of surface water flow was observed in the site area at the time of our reconnaissance. The general topography of the site area indicates that water drains towards the west. SITE GEOLOGY The soils on site are mapped as Alderw_ood gravelly loam, with 6 to 15% slopes. This nearly level to undulating soil is moderately well drained. It formed in glacial till under conifers, and it dominates the uplands of the Puget Sound Basin area. The existing topography, as well as the surficial and shallow subsurface soils in the area are the result of the most recent Vashon stade of the Fraser glaciation of 12,000 to 15,000 years ago, with subsequent weathering and erosion. A description of the surficial soils is included in the "Site Soils" section of this report. In general, Vashon glacial till underlies the entire building site. The till is approximately at 38 inches from the surface in the area where the homes will be built. SITE SOILS The King County Soil Conservation Survey has mapped the site soils as Alderwood gravelly loam in the building portion of the site. 10011 Blomberg Street SW, Olympia, WA 98512 Phone #: (206) 754-4612 Fax #: (206) 754-4848 UEOTECHNICAL TESTING LABORATORY A design and construction of a runoff retention facility will reduce the risk of surficial erosion or movement in the area of the new homes. CONCLUSIONS AND RECOMMENDATIONS Based on the results of our site reconnaissance and subsurface exploration program, and our experience in the area, it is our opinion that the site is suitable for the proposed homes. The slope located east of the home sites and the adjacent property are stable relative to deep-seated failure and will not be affected by the proposed construction. Proper erosion/sediment and drainage control measures will reduce or eliminate the potential for erosion in this area, and improve slope stability. In general, the gravelly sandy loam soils observed at the site are suitable for use as structural fill material. Material with less than 10 percent fines should be considered equivalent to select borrow material as per WSDOT 9-03.14(2). The till soils that occur on the site are moisture -sensitive and susceptible to disturbance when wet. Perched groundwater conditions may be associated with these soils during or following extended periods of precipitation. To reduce grading and construction costs, we recommend that earthwork be undertaken during dry weather conditions. Conventional commercial footings may be utilized at the site for support of the structures. We do recommend that roof drains be installed for the new homes. A vapor barrier is recommended for all slabs on grade. Pertinent conclusions and geotechnical recommendations regarding the design and construction of the proposed development are presented below. LANDSLIDE — EROSION HAZARD AREAS CLASSIFICATION The King County Ordinance defines a landslide hazard area as 1) one containing slopes equal to or greater than 30 percent with more than a 10-foot vertical relief, and containing soils described by the Soil Conservation Service (SCS) Soil Survey as having a "severe' limitation for building site development due to slope. The slopes located in the building portions of the site are less than 29 percent and the vertical relief is less than 10 feet. Based on this, these portions of the site do not meet the technical criteria of a landslide hazard. The soils at the site are mapped as Alderwood gravely loam throughout the entire site. The Alderwood soils are described as having a slight erosion hazard, based on the slope inclination. These soils do not meet the technical criteria of an erosion hazard. SLOPE STABILITY Based on our field observations, explorations and our experience with the soil types encountered on the property, we conclude that although portions of the slopes exceed 15 percent, they are generally stable relative to deep-seated failure in their present configuration. 10011 Blomberg Street SW, Olympia, WA 98512 Phone #: (206) 754-4612 Fax #: (206) 754-4848 GEOTECHNICAL TESTING LABORATORY No changes in slope stability are expected as a result of the proposed construction. Home construction will occur in the level portion of the site and based on appropriate engineering and building setback recommendations. Grading of the site is not needed but geotechnical recommendations are provided herein. Drainage shall be collected and directed to the site's storm water system. As previously discussed, weathering, erosion, and the resulting surficial sloughing and land sliding are natural processes that affect slope areas. Significant weathering typically occurs in the upper 2 to 3 feet and is the result of root penetration, wet/dry cycles and free/thaw cycles. These processes can be managed and the risk reduced through proper setback of the residences from the sloping area, including the storm water system. Erosion control recommendations in the building areas are provided in the "Building Location" and "Erosion Control" sections of this report. BUILDING LOCATION A building setback from landslide hazard areas is required unless evaluated and reduced by a licensed professional engineer. Cleaning, grading and filling within the setback area may be allowed if slope stability or the erosion hazard will not be adversely impacted. Based on our geotechnical evaluation of the site and our experience in the area, we recommend a building setback of 25 feet fr_om_the down slope area. (See slope profile Fig. 4). The building setback may be measured from the bottom of the footing to the face of the slope, in accordance with U.B.C. specifications. As previously discussed, weathering, erosion and the resulting surficial sloughing and shallow land sliding are natural processes that affect slope areas. As noted, no evidence of surficial raveling or sloughing was observed in the sloping portions of the site SEISMIC — LIQUEFACTION HAZARD Penetration test blow counts were taken during the boring phase. The soil conditions were assumed to be representative for the site conditions beyond the depths explored. Based on our review of the subsurface conditions, we conclude that the site soils are not susceptible to liquefaction. The near -surface soils are generally in a dense condition and the static water table is located well below the site. Shaking of the already dense soil is not apt to produce a denser configuration and subsequently excess pore water pressures are not likely to be produced. EROSION CONTROL It is our opinion that the potential erosion hazard of the site is not a limiting factor for the proposed home. Removal of natural vegetation is unnecessary since the site has been cleared where the new homes will be built. Temporary erosion control measures should not be needed during construction, but as soon as practical thereafter the recommended infiltration facility should be installed. 10011 Blomberg Street SW, Olympia, WA 98512 Phone #: (206) 754-4612 Fax #: (206) 754-4848 GEOTECHNICAL TESTING LABORATORY EARTHWORK SITE PREPARATION The debris from the previous home shall removed with all deleterious matter, including any existing foundations, abandoned utility lines and debris. The area of the home foundation should be proof rolled with a vibratory roller to insure that no soft areas are present. Based on our explorations, we estimate that very little stripping will be necessary to remove the root zones since most of the organics had been previously removed. Materials that cannot be used for landscaping or erosion control should be removed from the project site. If placement of fill material is required, the exposed sub -grade areas should be compacted to a firm and unyielding surface prior to placement of any fill. We recommend that a member of our staff evaluate the exposed sub -grade conditions after removal of debris and stripping is completed and prior to placement of structural fill (if necessary). The exposed sub -grade soil should be proof rolled with heavy vibratory roller as mentioned above. Any soft, loose or otherwise unsuitable areas delineated during proof rolling should be over -excavated and replaced with structural fill, based on the recommendations for structural fill. STRUCTURAL FILL All fill material should be placed as structural fill. The structural fill (if needed) should be placed in horizontal lifts of appropriate thickness to allow adequate and uniform compaction of each lift. Fill should be compacted to at least 90 percent of MDD (maximum dry density) as determined in accordance with ASTM D-1557 to within 2 feet of sub - grade and 95 percent MDD in the upper 2 feet. The appropriate lift thickness will depend on the fill characteristics and compaction equipment used. We recommend that the appropriate lift thickness shall be 12 inches. We recommend that density tests shall be performed on all fill to meet the above requirements. The suitability of material for use as structural fill will depend on the gradation and moisture content of the soil. As the amount of fines (material passing No. 200 sieve) increases, soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult to achieve. During wet weather, we recommend the use of well -graded sand and gravel with less than 10 percent (by weight) passing the No. 200 sieve based on that fraction passing the 3/-inch sieve. If prolonged dry weather prevails during the earth work and foundation installation phase of construction, a somewhat higher (up to 15 percent) fines content will be acceptable. Material placed for structural fill should be free of debris, organic matter, trash and cobbles greater than 8 inches in diameter. The moisture content of the fill material should be adjusted as necessary for proper compaction. 10011 Blomberg Street SW, Olympia, WA 98512 Phone #: (206) 754-4612 Fax #: (206) 754-4848 GEOTECHNICAL TESTING LABORATORY SUITABILITY OF ON -SITE SOILS AS FILL During dry weather construction, any non -organic on -site soil may be considered for use as structural fill, provided it meets the criteria described above in the structural fill section and can be compacted as recommended. If the material has over -optimum moisture content when excavated, it will be necessary to aerate or dry the soil prior to placement as structural fill. The workability of material for use as structural fill will depend on the gradation and moisture content of the soil. As the amount of fines increases, soil becomes increasingly more sensitive to small changes in moisture content and adequate compaction becomes more difficult or impossible to achieve. In general, the native granular soils (sand and gravel) encountered in the test borings at the site are suitable for use as structural fill. This material is comparable to commercial "pit run' sand and gravel mined from a gravel pit north of the site. CUT AND FILL SLOPES All job site safety issues and precautions are the responsibility of the contractor providing the services. The following cut/fill slope guidelines are provided for planning purposes. No cut slopes will likely be necessary during grading operations. However as a general guide, temporary slopes of 1 to 1 (horizontal to vertical) or flatter may be used for temporary cuts in the upper 3 to 4 feet of the glacially consolidated soils that are weathered to a looselmedium dense condition. Temporary slopes of 1/2 to 1 or more may be used in the un-weathered dense to very dense sands and gravels or till. These guidelines assume that all surface loads are kept at a minimum distance of at least one half the depth of the cut away from the top of the slope and that significant seepage is not present on the slope face. Flatter cut slopes will be necessary where significant raveling or seepage occurs. Surface drainage should be directed away from all slope faces. Some minor raveling may occur with time. All disturbed slopes should be seeded as soon as practical to facilitate the development of a protective vegetative cover or otherwise protected. FOUNDATION SUPPORT All exterior footing elements should be embedded as least 12 inches below grade for frost protection. We recommend a minimum width of 1.5 feet for continuous wall footings. Footings founded as described above can be designed using an allowable soil bearing capacity of 2,000 psf (pounds per square foot) for combined dead and long-term live loads in areas of medium dense to dense soils (sand and gravel). Where the footings are founded on the very dense undisturbed glacial till or advance outwash material, the allowable bearing capacity may be increased to 4,000 psf for combined dead and long-term live loads. We expect that the very dense till soils will be encountered in all portions of the foundation area. The weight of the footing and any overlying backfill may be neglected. 10011 Blomberg Street SW, Olympia, WA 98512 Phone #: (206) 754-4612 Fax #: (206) 754-4848 GEOTECHNICAL TESTING LABORATORY The allowable bearing value may be increased by one-third for transient loads such as those induced by seismic events or wind loads. Lateral loads may be resisted by friction on the base of footings and floor slabs and as passive pressure on the sides of footings. We recommend that an allowable coefficient of friction of 0.40 be used to calculate friction between the concrete and the underlying soil. Passive pressure may be determined using an allowable equivalent fluid density of 275 pcf (pounds per cubic foot). We estimate that settlements of footings designed and constructed as recommended will be less than I inch for the anticipated load conditions, with differential settlements between comparably loaded footings of % inch or less. Most of the settlements should occur essentially as loads are being applied. However, disturbance of the foundation sub - grade during construction could result in larger settlements than predicted. FLOOR SLAB SUPPORT Slabs -on -grade (if used) should be supported on medium dense or denser native soils or on structural fill prepared as described in the "Structural Fill" section of this report. We recommend that floor slabs be directly underlain by a minimum 4-inch thickness of coarse sand and/or gravel containing less than 2 percent fines (by weight). The drainage material should be placed in one lift and compacted to an unyielding condition. A synthetic vapor barrier should be used for the control of moisture migration through the slab, particularly where adhesives are used to anchor carpet or tile to the slab. A thin layer of sand may be placed over the vapor barrier and immediately below the slab to protect the liner during steel and/or concrete placement. The lack of a vapor barrier may result in wet spots on the slab. A sub grade modulus of 400 kcf (kips per cubic foot) may be used for floor slab design. We estimate that settlement of the floor slabs designed and constructed as recommended, will be %Z inch or less. SUB -GRADE AND RETAINING WALLS No retaining walls will likely be utilized in the construction of the homes. If retaining walls are built exceeding four ft. in height, an engineer should be consulted and local building code requirements followed. Walls less than four ft. in height will not adversely affect the property and will not need to be engineered. PAVEMENT SUB GRADE On the basis of the results of laboratory tests and the assumed traffic counts of the proposed project, the pavement profile should consist of the following recommendations: EXISTING SUB GRADE: 1.) All sub grade preparation work to be performed should be monitored by a representative of our firm. 2.) Over -excavate any areas that exhibit pumping of the sub grade soils at least 12 inches (or as directed by a representative from our firm). Replace with gravel base material. If the sub grade is saturated or pumping excessively after over -excavating, then it may be necessary to place quarry spall on the sub - grade prior to placement of any gravel base material. 10011 Blomberg Street SW, Olympia, WA 98512 Phone #: (206) 754-4612 Fax #: (206) 754-4848 GEGTECHNICAL TESTING LABORATORY 3.) On the basis of the existing soils type, the onsite conditions, and the anticipated traffic conditions, we recommend that the existing sub -grade being compacted to 95% of the maximum dry density as determined by ASTM D-1557 (Modified Proctor). 4.) Under certain site conditions, the existing sub -grade can be accepted by proof -rolling the sub -grade using a fully loaded dump truck. This procedure (if used) should be witnessed and accepted by a representative of our firm. GRAVEL BASE: 1.) The gravel base material should consist of 6 inches of material that is placed and compacted to 95% of the•dry density as determined by ASTM D-1557 (Modified Proctor). 2.) The gravel base material should consist of a clean free draining granular material that has less than 10% passing the #200 sieve. This material should meet one of the following specifications, WSDOT Section 9-03.10 Aggregate for Gravel Base, WSDOT Section 9-03.14(1) Gravel Borrow, WSDOT Section 9- 03.14(2) Select Borrow, APWA Class A Pit Run, or APWA Class B Pit Run. Material that does not meet one of the specifications should be submitted for approval. 3.) The material should be placed in lifts not to exceed 9 inches, with each lift being compacted and verified. CRUSHED SURFACING: 1.) The layer of the crushed surfacing material should consist of 2 inches of WSDOT Section 9-03.9(3) Crushed Surfacing (Base Course Specs) or at the contractors option (Top Course) and compacted to 95% of the maximum dry density as determined by ASTM D-1557 (Modified Proctor). 2.) The crushed surfacing material should be placed to provide the proper grade and drainage for the asphalt pavement. ASPHALTIC CONCRETE PAVEMENT: 1.) The asphalt pavement should consist of at least 2.0 inches of WSDOT Class B asphalt that is placed and compacted to at least 91 % of the theoretical maximum density as determined by ASTM D-2041 (Rice Method). 2.) The pavement may be placed in one lift of 2.0 inches, compacted and verified. 3.) Provide a tack coat on all concrete surfaces that the pavement will be placed against, and for multiple lifts that are not placed at the same time. SITE DRAINAGE All ground surfaces, pavements and sidewalks should be sloped away from the residences and associated structures. 10011 Blomberg Street SW, Olympia, WA 98512 Phone #: (206) 754-4612 Fax #: (206) 754-4848 GEGTECIMCAL TESTING LABORATORY Surface water runoff should be controlled by a system of drainage swales,_ and allowed to infiltrate_into the_soil by natural means. We recommend that conventional roof drains be installed for the homes and discharged to the _d_e_signeUdischarge area. Based on the results of our test borings and the percolation holes dug for this purpose in the infiltration area, we recommend a desiL-n.infiltratio-n rate of .1_Czinch_es_per ho..ur. An appropriate factor of safety should be applied to this infiltration rate. We do not expect any adverse affects on the recharge condition of the groundwater system. The infiltration of a portion of the site's storm water runoff will match the existing shallow groundwater recharge conditions. Because the recharge of the local shallow aquifer will not be significantly affected, the net impact to the regional aquifer will be insignificant. The recharge area for the regional aquifer essentially occurs over the entire Federal Way area.
