PO Box 1326 Issaquah, WA 98027-0053 FiLE CITY HALL Way 33325 8th Avenue South Federal Way, WA 98003-6325 (253) 835-7000 wwwcityoffederalway. com RE: File #12-101282-00-SH; SHORELINE SUBSTANTIAL DEVELOPMENT PERMIT EXEMPTION Shelley, 29635 20`h Place SW, Federal Way Dear Mr. Jensen: The Community and Economic Development Department has completed the technical review of the proposed construction of a detached cabana to be located at 29635 201h Place SW, Federal Way. The improvement is within 200 feet of the ordinary high water mark of Puget Sound. The above -referenced property has been designated `Rural' by the City's Shoreline Master Program (SMP).1 PROPOSAL The applicant proposes to construct a detached 964 square -foot cabana 53 feet landward from the ordinary high water mark. The construction proposal includes connecting to the existing on -site septic system. The site is developed with a single-family residence, a detached garage, and other accessory structures. The proposed height of the structure does not exceed 30 feet above average building elevation; grading for the septic upgrades will not exceed 250 cubic yards and will not involve the placement of fill waterward of the ordinary high water mark. SHORELINE SUBSTANTIAL DEVELOPMENT PERMIT EXEMPTION Washington Administrative Code (WAC) 173-27-040 identifies actions exempt from the requirements to obtain a shoreline substantial development permit. WAC 173-27-040(2)(g) exempts, under specific circumstances, the construction on shorelands by an owner of a single-family residence and normal appurtenances. Following review of submitted site plans, staff has concluded the proposed improvement meets the terms of the referenced exemption and is consistent with the policies of the SMP and the State's Shoreline Management Act; therefore, a shoreline substantial development permit is not required. STATE ENVIRONMENTAL POLICY ACT (SEPA) EXEMPTION WAC 197-11-800(1) specifically exempts the construction of any residential structures up to four dwelling units. The city has determined the proposal is exempt from SEPA review. CONDITIONS OF APPROVAL 1. The ordinary high water mark must be staked prior to footings and setback inspection. 2. All construction work, stockpiling of construction materials, and vehicle access must be landward of the staked ordinary high water mark. 3. Construction debris shall not be disposed of on the beach. 1 Please note that a new SW was adopted in early 2012; however, this permit is vested to the older regulations. Mr. Jensen March 29, 2012 Page 2 CLOSING This exemption is not an approval to begin construction. No work on the site may begin until the necessary permits are obtained. If you have any questions regarding this letter, please contact Kari Cimmer, Permit Center Supervisor, at 253-835-2629 or karic cityoffederalway.com.

Per our telephone conversation and the attached email, the applicant is proposing to construct a cabana on their property. Because the structure will be located below the existing wastewater tankage, we have designed a new septic tank with effluent pump that will serve the new structure. The effluent from the cabana will be pumped up to the existing dose tank. Also included is a copy of a site plan signed by City of Federal Way indicating that the proposed area of development is clear of any Critical Areas. Pursuant to the attached email from you, a repair application has also been submitted with this application. Because the application is not associated with a system failure, only the application face page has been included. Once the new system components have been installed, we will inspect and test the new components and prepare an updated record drawing for Health Department approval. Please note that the property is gated and you will need to contact the owner, Andrea Shelley, for access. Andrea can be reached at either 253-927-9386 (home) or 253-670-3500 (mobile). Thank you for your reconsideration of this application. Should you have any questions, please don't hesitate to call. Respectfully, Rocky R.

The location of the site is shown on the attached Site Vicinity Map, Figure 1. Our understanding of the project is based on our discussions with you, our September 21, 2011 site visit, and our experience in the area. We understand that you propose to construct a new cabana on the lower shoreline bench area in the northwest portion of the parcel. The new cabana will have approximately 1,053 square feet of new impervious roof area, which includes roof eaves. The purpose of our services was to evaluate the surface conditions at the site as a basis for assessing potential adverse impacts to and from the slopes located within the site area. We have reviewed the September 13, 2011 letter from the City of Federal Way Permit Center Supervisor requiring a soils report describing the critical areas and possible impacts of the proposed development on the site. Specifically, our scope of services for the project included the following: 1. Visiting the site and conducting a geologic reconnaissance to assess the site's soil, groundwater and slope conditions. 2. Addressing the appropriate geotechnical regulatory requirements for the proposed site development. No subsurface exploration or laboratory testing were completed as part of the scope for this assessment. However, we reviewed the soil logs and:geotechnical recommendation included in the Soil and Slope Survey and Geotechnical Engineering Study prepared by Krazan & Associated, Inc. dated January 15, 2001 for the site. SITE CONDITIONS The subject parcel is located at 29635 — 201h Place SW in the Lakota area of Federal Way, Washington. The parcel is irregular in shape, generally measures 1,050 feet north to south by 420 feet east to west, and encompasses approximately 7.7 acres. The site is bounded by 20th Place SW on the east, existing single family residences on the south, and RESUBMITTED 11-103269 OCT 062011 CITY OF FEDERAL WAY CDS Shelley.20thPIS.GHA October 4, 2011 Page 2 southwest, Puget Sound on the north, and by an undeveloped wooded lot on the west. The parcel is currently developed with an existing single-family residence with a daylight basement and an existing barn. The site has a low bank marine shoreline protected from shoreline erosion by an existing concrete bulkhead. The site is located on the north margin of the Federal Way glacial upland area. The topography, beginning along the southern boundary of the parcel, slopes down from south to north at inclinations of 13 to 38 percent. The slope extends across grass pastureland with scattered trees towards the location of the existing buildings. The ground surface near the existing structures flattens to inclinations of nearly flat to 28 percent. The area below the existing residence slopes down to a wide walking path and down a 25 percent slope with up to 15 feet of relief. The toe of the slope flattens onto a level bench for approximately 50 to 110 linear feet towards the bulkhead. The proposed shoreline cabana will be located at the toe of this lower slope on the southern portion of the shoreline bench. Localized areas of slopes steeper than 40 percent are located in the upper pasture areas (southeast corner of the site), across the center of the pasture area, and in the northwest corner of the parcel. The localized steep slope areas have vertical relief in access of 10 feet, but are located more than 100 feet from the proposed location of the cabana. Total topographic relief across the site is on the order of 195 feet. The existing and proposed site configuration is shown on the attached Site Plan, Figure 2. Vegetation on the site consists of grass lawns and landscaped areas with scattered trees. Groundwater seepage as indicated by horsetail and surface water was observed near the western property line at the time of our site visit. A drain was observed below this area that collected and tightlined the seepage away from the eastern portion of the site. This area is located greater than 250 feet from the area of the proposed development. No evidence of erosion, soil movement, landslide activity or deep-seated slope instability was observed at the site or the adjacent areas at the time of our site visit. Site Soils The USDA Natural Resource Conservation Service (NRCS) Web Soil Survey for King County maps the soils in the western portion of the site as Alderwood gravelly sandy loam (AgB & AgD) with Coastal Beach deposits (Cb) along the shoreline area. The Alderwood soils are derived from glacial till and formed on 0 to 6 or 15 to 30 percent respectively. The Alderwood (steeper AgD) soils are listed as having a "severe: slopes" limitation for building site development for dwellings and small commercial buildings and a "moderate to severe" hazard_ of erasiomPince the excavation will be on the flatter and lower portion of the site, we interpret this are to'be underlain by the gently sloping Alderwood (AgB) soils that are listed as having a "slighf" hazard of erosion. A copy of the SCS map for the site vicinity is attached as Figure 3. Site Geology The Geologic Map-Qtthe Poverty Bay 7.5-minute Quadrangle, Washington Derek B. Booth, Howard H. Waidrorf,`di d Kathy G. Troost (2003} indicates the site underlain by mass wasting deposits (Qmw) with Pre -Olympia coarse grained glacial deposits (Qpogc). The mass wasting deposits are described as coiluvium soil, and landslide debris with indistinct morphology likely. Areas mapped as landslide debris (Qls) are located along the shoreline west and east of the subject site. Given the size and extent of the mapped landslide deposit, it appears that this area may be representative of a large, prehistoric landslide associated with the retreat of the prehistoric ice mass and subsequent unloading. At the time of our site visit, no evidence of ongoing or recent landslide activity was observed. An excerpt of the above referenced map is included as Figure 4. Shelley.20thPIS.GHA October 4, 2011 Page 3 The Washington State Department of Ecology Coastal Atlas website maps the slope stability on the western portion of the site and surrounding areas as "stable" and "intermediate". However, most of the Poverty Bay Park area, west of the subject parcel, is mapped by the Coastal Zone Atlas as "Unstable old LaridslideP. This area generally aligns with the USGS mapping of landslide debris, but the area of "Unstable old Landslide" does not extend as far east as the USGS mass wasting area. A copy of the Coastal Atlas is included as Figure 5. Oblique aerial photographs dating back to 1977 were also obtained from the Coastal Atlas website. These photographs depict the site and vicinity in the same general condition over time. No evidence of instability or erosion is noted on the photographs. Copies of the photographs are attached as Figure 6a and 6d. GEOLOGIC HAZARDS The Federal Way City Code states "geologically hazardous areas" means areas which because of their susceptibility to erosion, landsliding, seismic or other geological events are not suited to siting commercial, residential or industrial development consistent with public health or safety concerns, Geologically hazardous areas include the following areas: (1) "Erosion hazard areas" are those areas having a severe to very severe erosion hazard due to natural agents such as wind, rain, splash, frost action or stream flow. (2) "Landslide hazard areas" are those areas potentially subject to episodic downslope movement of a mass of soil or rock including, but not limited to, the following areas: (a) Any area with a combination of: (i) Slopes greater than 15 percent; (ii) Permeable sediment, predominately sand and gravel, overlying relatively impermeable sediment or bedrock, typically silt and clay; and (iii) Springs or groundwater seepage. (b) Any area which has shown movement during the Holocene epoch, from 10,000 years ago to the present, or which is underlain by mass wastage debris of that epoch. (c) Any area potentially unstable as a result of rapid stream incision, stream bank erosion or undercutting by wave action. (d) Any area located in a ravine or on an active alluvial fan, presently or potentially subject to inundation by debris flows or flooding. (e) Those areas identified by the United States Department of Agriculture Soil Conservation Service as having a severe limitation for building site development. (f) Those areas mapped as Class U (unstable), UOS (unstable old slides), and URS (unstable recent slides) by the Department of Ecology. (g) Slopes having gradients greater than 80 percent subject to rockfall during seismic shaking. (2) "Seismic hazard areas" are those areas subject to severe risk of earthquake damage as a result of seismically induced ground shaking, slope failure, settlement or soil liquefaction, or surface faulting. These conditions occur in areas underlain by cohesionless soils of low density usually in association with a shallow groundwater table. (4) "Steep slope hazard areas" are those areas with a slope of 40 percent or greater and with a vertical relief of 10 or more feet, a vertical rise of 10 feet or more for every 25 feet of horizontal distance. A slope is delineated by establishing its toe and top, and measured by averaging the inclination over at least 10 feet of vertical relief. Shelley.20thPIS.GHA October 4, 2011 Page 4 CONCLUSIONS Based on our observations and literature review, it is our opinion that a landslide hazard, erosion hazard area, seismic hazard area, or steep slope area do not exist on or within 25 feet of the project site. Specific comments are provided below: Erosion The City of Federal Way..evlsed Code Section 19.05 defines erosion hazard areas as those areas having a_ "severe"or "very severe" -erosion hazard due to natural agents such as wind, rain, splash, frost action or stream flow. The City of Federal Way GIS maps the site as being within an Erosion Hazard Areas. The mapped SCS soils types have a "slight or "moderate to severe" erosion hazard, depending on inclination. Therefore, the site soils -do riot meet the definition of an erosion hazard area. Therefore, no buffers should be imposed by the City. Landslide Hazard Areas per City of Federal Way Based on the above criteria, we offer the following comments. The site has slopes / 1 steeper than 15 percent, but no adverse contacts are mapped or inferred to. be underlying the site. Springs or seeps were observed near the western property line at the time of our site visit. These are located above an existing drain which is collecting water and diverting flow away from the site. As stated above, the USGS maps indicate areas of mass wasting on the subject parcel and landslide debris off site to the west and east. The Coastal Zone Atlas indentifies areas of "unstable old landslide" west of the site. However, no areas that exhibit evidence of movement either past or recent were observed on or within 300 feet of the proposed cabana. No areas of rapid stream incision or stream bank were noted. The, shoreline on the site and adjacent parcels is protected from undercutting by wave action by existing bulkheads. The site is located west of 20'' Place SW and a shallowly incised streaV channel (east of 201n Place SW). The site is listed having either "slight" or "moderate to severe" erosion hazards not "severe" for building limitations by the SCS. Lastly, jhe site does not have slopes steeper than 80 percent. Based on our observations and literature review, the site has one of the above landslide hazard indicators on or within 25 feet of the site (mapped mass wasting). However, no evidence of recent or ongoing landslide activity was observed on the subject parcel or within the vicinity of the proposed development at the time of our site visit. Therefore, in our ` opinion, the site does not constitute an active landslide hazard area and no prescriptive buffers should be imposed by the City of Federal Way. Seismic Hazard The Federal Way Revised Code defines seismic hazard areas as those areas subject' to severe risk of earthquake damage as a result of seismically induced ground shaking, slope, failure, settlement or soil liquefaction, or surface faulting. These conditions occur in areas underlain by cohesionless soils of low density usually in association with a shallow groundwater table. Based on our observation and the subsurface units mapped at the site, we interpret the structural site conditions to correspond to a seismic Site Class "C" in accordance with Table 1613.5.2 in the 2006 IBC (International Building Code) documents. This is based on the likely range of equivalent SPT (Standard Penetration Test) blow counts for the soil types observed in the site area. These conditions were assumed to be representative for the conditions based on our experience in the vicinity of the site. These soils are not prone to liquefaction and do not constitute a seismic hazard area. Shelley.20thPIS.GHA October 4, 2011 Page 5 Steep Slope Hazard Based on our observations during our site reconnaissance and exploration, there are localized areas of slopes steeper than 40 percent on the subject site. These areas are generally located south and west of the existing residence, and more than 100 feet from the proposed cabana. Therefore the site does not meet the criteria of a steep slope hazard area. Site Drainage All ground surfaces, pavements and sidewalks at the site should be sloped away from the new residence. The lot should also be carefully graded to ensure positive drainage away from all structures and property lines. Surface water runoff from the roof area, driveways, perimeter footing drains, and wall drains, should be collected, tightlined, and conveyed to an appropriate discharge point. Since the proposed development will include less than 2,000 square feet of new or replaced Impervious surfaces, the site does not meet the minimum criteria stated in Small Site Drainage Requirements per Appendix C of the 2009 King County Surface Water Design Manual (KCSWDM) for a drainage plan. Therefore no drainage plan and report is prepared for the site. LIMITATIONS We have prepared this report for the Shelley Family, Terry Jensen Custom Homes, and other members of the design team for use in evaluating a portion of this project. Subsurface conditions described herein are based on our observations of exposed soils on the parcel. This report may be made available to regulatory agencies or others, but this report and conclusions should not be construed as a warranty of subsurface conditions. Subsurface conditions can vary over short distances and can change with time. Within the limitations of scope, schedule and budget, our services have been executed in accordance with generally accepted practices in this area at the time this report was prepared. No warranty, express or implied, should be understood. Shelley.20thPIS.GHA October 4, 2011 Page 6 We have appreciated working for you on this project.

PO Box 1326 Issaquah, WA 98027 FILE Re: Permit #11-103269-00-SF; LAND USE COMMENTS Shelley; 29635 201h Place SW, Federal Way Dear Mr. Jensen: On August 12, 2011, the City of Federal Way's Community and Economic Development Department received your application for a building permit to, "Construct 964 square foot cabana." An initial review of the material you submitted indicates the following issues that must be addressed prior to land use approval. Referenced Federal Way Revised Code (FWRC) code sections are included. A. Geologically Hazardous Area This property has been mapped as a geologically hazardous area (GHA) due to potential erosion and landslide hazards. Please see FWRC 19.05.070 (enclosed) for a definition of erosion and landslide hazards areas. Pursuant to FWRC 19.160.010, please submit: "A soils report prepared by a qualified professional engineer licensed in the state which describes how the proposed development will impact each of the following on the subject property and nearby properties: (i) Slope stability, landslide hazard and sloughing. (ii) Seismic hazards. (iii) Groundwater. (iv) Seeps, springs and other surface waters. (v) Existing vegetation. " The city's file for the residence constructed in 2000 included a "Soil and Slope Survey and Geotechnical Engineering Study" prepared by Krazan & Associated, Inc. (1501 15"' Street NW, Suite 106, Auburn, WA 98002). The report addressed conditions in the area of the main residence. An addendum to the report that extends to include the area of construction for the proposed cabana would be acceptable. File #11-103269-00-SF Doc I D 458773 Mr. Terry Jensen Page 2 September 13, 2011 If the proposed project is found to be within a GHA or its 25 foot buffer, pursuant to FWRC 19.160.010(2), the Director of Community and Economic Development may permit the development activity if no reasonable alternative exists and if the development activity will not lead to or create any increased slide, seismic, or erosion hazard. Please address these criteria in the resubmitted material. However, if after analysis, the qualified professional engineer believes this property is not within a geologically hazardous area, the geotechnical report can address the FWRC-based reasons why this conclusion has been reached. Please note that the plans and report may be reviewed by the city's consuiWnt aad.th - applicant shall cover the cost of the third party review, as required in accordance with Lh, city',q a rtance. B. Stream A major stream appears to be located within 100 feet of this proposed project. Per FWRC 19.165.010(1) (enclosed), no improvement may be located in a stream or within 100 feet outward from the ordinary high water mark of that major stream. Please depict the stream location on a revised site plan. C. Environmental Review (SEPA) Pursuant to FWRC 14.30.030, single-family construction is subject to environmental review (SEPA) when the project is located within a critical area. FWRC 14.30.010 (enclosed) states that GHA's and streams are designated as critical areas. If it is determined that any portion of the construction is located within 25 feet of a GHA, or 100 feet of a major stream, environmental review will be required. If required, an environmental checklist must be submitted and reviewed prior to the city issuing an environmental decision. All property owners within 300 feet of the site must be notified of that decision. The notification includes a 14-day comment and 14-day appeal period. Environmental review must be concluded before a building permit can be issued for the project. If it is determined that SEPA is required per FWRC 19.40.010 (enclosed), a preapplication meeting is required, unless otherwise waived. A waiver may be granted by the Director of Community and Economic Development after consideration of a written request meeting the criteria found in FWRC 19.40.030(2) (enclosed). Representatives from all city permit review divisions, as well as the South King Fire & Rescue and Lakehaven Utility District, will attend the meeting and will discuss their particular requirements as they relate to your project. I have enclosed a master land use application and Preapplication Conference handout, which is a checklist of the items you'll need to submit when applying for the preapplication meeting. Please note there is a $464.00 nonrefundable fee for the meeting and it takes three to four weeks to get on the schedule from the time the plans are submitted. D. Shoreline The property is located within a Washington State designated shoreline —rural environment. As such, the project is subject to state and local shoreline regulations. File#I1-103269-00-SF Doc I.D. #58773 Mr. Terry Jensen Page 3 September 13, 2011 Pursuant to FWRC 15.05.050(3)(c) (enclosed), "All development shall be required to provide adequate surface water retention and sedimentation facilities during the construction period." Additionally, per FWRC 15.05.050(3)(fl (enclosed), "...collection facilities to control and separate contaminants shall be required where storm water runoff from impervious surfaces would degrade or add to the pollution of recipient waters of adjacent properties." The submitted site plan does not indicate what method to be used to control runoff and where this will be placed around the project site, or the location of the stringline setback. Please provide a revised site plan depicting the method and location of these control measures. Please include the location of any utilities to be supplied to the proposed cabana. SUMMARY In summary, please provide the following: A. Two copies of a new or revised geotechnical report that addresses issues in item A of this letter. B. Five copies of a revised site plan depicting the changes noted in items A — D, any identified geologically hazardous areas and stream location. Please use the enclosed Resubmittal Information form when submitting these items. Review by other city staff is occurring simultaneously, so you may be contacted by other city staff. I will continue my review upon receipt of the requested information. If you have questions concerning these requirements, please contact me at (253) 835-2629, or erniiteenterimcitvoffederalwa .cone.

"Geologically hazardous areas" means areas which because of their susceptibility to erosion, landsliding, seismic or other geological events are not suited to siting commercial, residential or industrial development consistent with public health or safety concerns. Geologically hazardous areas include the following areas: (1) "Erosion hazard areas" are those areas having a severe to very severe erosion hazard due to natural agents such as wind, rain, splash, frost action or stream flow. (2) "Landslide hazard areas" are those areas potentially subject to episodic downslope movement of a mass of soil or rock including, but not limited to, the following areas: (a) Any area with a combination of- (i) Slopes greater than 15 percent; (ii) Permeable sediment, predominately sand and gravel, overlying relatively impermeable sediment or bedrock, typically silt and clay; and (iii) Springs or groundwater seepage. (b) Any area which has shown movement during the Holocene epoch, from 10,000 years ago to the present, or which is underlain by mass wastage debris of that epoch. (c) Any area potentially unstable as a result of rapid stream incision, stream bank erosion or undercutting by wave action. (d) Any area located in a ravine or on an active alluvial fan, presently or potentially subject to inundation by debris flows or flooding. (e) Those areas identified by the United States Department of Agriculture Soil Conservation Service as having a severe limitation for building site development. (f) Those areas mapped as Class U (unstable), UOS (unstable old slides), and URS (unstable recent slides) by the Department of Ecology. (g) Slopes having gradients greater than 80 percent subject to rockfall during seismic shaking. (3) "Seismic hazard areas" are those areas subject to severe risk of earthquake damage as a result of seismically induced ground shaking, slope failure, settlement or soil liquefaction, or surface faulting. These conditions occur in areas underlain by cohesionless soils of low density usually in association with a shallow groundwater table. (4) "Steep slope hazard areas" are those areas with a slope of 40 percent or greater and with a vertical relief of 10 or more feet, a vertical rise of 10 feet or more for every 25 feet of horizontal distance. A slope is delineated by establishing its toe and top, and measured by averaging the inclination over at least 10 feet of vertical relief. 19.160.010 Limitations. (1) This section regulates development activities and land surface modifications on or within 25 feet of a geologically hazardous area. (2) The director of community development may permit development activities, land surface modifications or the installation and maintenance of landscaping normally associated with residential, commercial or park use on or within 25 feet of a geologically hazardous area if no reasonable alternative exists and only if the development activity or land surface modification will not lead to or create any increased slide, seismic or erosion hazard. (3) Before approving any development activity or land surface modification under this section, the city may require the applicant to submit the following information: (a) A soils report prepared by a qualified professional engineer licensed in the state which describes how the proposed development will impact each of the following on the subject property and nearby properties: (i) Slope stability, landslide hazard and sloughing. (ii) Seismic hazards. (iii) Groundwater. (iv) Seeps, springs and other surface waters. (v) Existing vegetation. File #11-103269-00-SF FWRC Page 1 Doc. I.D. #58773 (b) Recommended foundation design and optimal location for roadway improvements. (c) Recommended methods for mitigating identified impacts and a description of how these mitigating measures may impact adjacent properties. (d) Any other information the city determines is reasonably necessary to evaluate the proposal. (4) If the city approves any development activity or land surface modification under this section, it may, among other appropriate conditions, impose the following conditions of approval: (a) That the recommendations of the soils report be followed. (b) That the applicant pay for the services of a qualified professional engineer selected and retained by the city to review the soils report and other relevant information. (c) That a qualified professional engineer be present on -site during all land surface modification activities. (d) That trees, shrubs and groundcover be retained except where necessary for approved development activities on the subject property. (e) That additional vegetation be planted in disturbed areas. FWRC 15.05.050(3)(c) & (3)(f) (c) All development shall be required to provide adequate surface water retention and sedimentation facilities during the construction period. (f) In addition to any requirements imposed by FWRC Title 6, collection facilities to control and separate contaminants shall be required where stormwater runoff from impervious surfaces would degrade or add to the pollution of recipient waters of adjacent properties. FWRC 15.05.050(4) (4) Residential development. Single-family and multiple -family residential development may be permitted in the urban environment subject to the general requirements of Chapters 19.200 and 19.205 FWRC, and the following: (a) Single-family or multiple -family residential development is permitted in the underlying zone classification. (b) Residential development is prohibited waterward of the ordinary high water mark. (c) Setbacks. (i) Single-family residential development shall maintain a minimum setback behind the stringline setback, or 50 feet from the ordinary high water mark, whichever is greater, except in the following cases: (A) If the property is undeveloped and reasonable use of the property cannot occur without further encroachment of the setback due to physical constraints of the lot, then the director of community development services can reduce the setback to the minimum necessary in order to build a single-family home, but in no case less than 30 feet from the ordinary high water mark. For the purposes of this section, "physical constraints" includes but is not limited to that constraint created by the installation and location of a new septic system when public sewer services not available. (B) If the property is developed with a single-family home beyond the stringline setback or within 50 feet of the ordinary high water mark if there are no adjacent residences, then the residence can only be added to if the addition will not make the structure any more nonconforming as to its setback and the height of the addition within the setback area is not increased, or the applicant may request a shoreline variance and conditional use permit. (C) If single-family residential development is proposed on a lot where properties adjacent to both sides of the lot are developed in single-family residences located less than 50 feet from the ordinary high water mark, then the proposed residential development may be located the same distance from the ordinary high water mark as the adjacent residences (using stringline method) or 30 feet from the ordinary high water mark, whichever is greater. (D) If the residential development is proposed on shorelines that include one or more sensitive areas, as defined in FWRC Title 9, such development shall maintain setbacks in accordance with the regulations and procedures set forth in FWRC Title 9, Division V. File #11-103269-00-SF FWRC Page 2 Doe 1 D #58773 FWRC 19.165.010(1) Setbacks. (1) No land surface modification or improvements may take place or be located in a stream or within the following setback areas except as allowed within this division: (a) The setback area for a major stream includes all areas within 100 feet outward from the ordinary high water mark of a major stream.

Discussions regarding site conditions are presented herein, together with conclusions and recommendations pertaining to site preparation and grading of the steep slope on the north side of the proposed residence addition. The project location is shown on the Vicinity Map, Figure 1. The approximate test pit locations are presented on the Site Plan, Figure 2 of this report. The test pit logs are presented in Appendix A. Purpm and Scope This study was undertaken to address city slope and residence siting concerns as expressed by Brian Alexander of Jensen construction. In conducting this study we have evaluated the stability of the steep slope areas adjacent to the proposed building addition, ascertained soil and groundwater conditions in the portion of the slope to be removed with daylighting of the basement portion of the addition, and provide criteria for site preparation and slope cuts. The provision of design recommendations for foundations, retaining walls, and recommendations for construction or permanent underpinning and/or shoring are beyond the scope of this report. It is our understanding that others will develop these recommendations as part of the design process. Our services were performed in accordance with our proposal dated December 28, 2000, and is generally outlined as follows: 1. A reconnaissance of the site and adjacent areas was completed by a member of our engineering geology staff to evaluate the general ground surface conditions. 2. A field investigation consisting of three hand dug test pits ranging in depth from 8 to 12 feet was completed. The field investigation was performed to evaluate the subsurface soil conditions on the site slopes and provide a basis for our conclusions and recommendations.

Representative soil samples were obtained from the test pits and returned to Our laboratory for visual examination. The samples have been retained should specific laboratory testing be required at a later time. 4. Evaluation of the surface and subsurface information and engineering analysis to develop the recommendations contained in this report to aid in project design. Proposed Construction Based on discussions with Brian Alexander and the site plan prepared by Sadler/Barnard & Associates, Inc., dated December 19, 2000, we understand that the addition will have a footprint of roughly 3500 square feet and contain a full basement level daylighted to the north. From Mr. Alexander we understand that the finished basement floor elevation will be on the order of eight to 10 feet below current ground level at the north side of the addition. Some variability of the finished slope heights is anticipated. However, it is expected that daylighting of the basement excavation through the north facing slope will generally result in the removal of all but the lower four to six feet of the existing slope and general flattening of the remaining slope below the cut. Following construction all areas of disturbed soils and vegetation will re -landscaped and vegetated or otherwise protected from erosion. Site Location and Descrigtim The subject site is located near the north end of 20`h Place Southwest in Federal Way, Washington, and overlooks Puget Sound to the north. As indicated above, the property has been previously developed with a single-family residence and concrete drive/parking area approximately 35 feet above the level of the beach. The specific slope section under consideration, which is below and west of the existing structure, has a height of approximately 12 to 15 feet. The area between the present home and the beach has been terraced and fully landscaped. The present terrace structures appear to have been cut into the natural slopes and it is our understanding that the present property owner has pre-1940 photographs of the property showing the terraces before they were fully vegetated. The terraces and slopes across the property appear stable and show no evidence of ground movement under the present conditions. Slope grades between the building site and the terrace below generally range from near 35% to 50%. To the east slopes are on the order of 40% to 56% and to the west 52% to 60 %. The terraced area below the building site varies in width from about 25 to nearly 40 feet with a general downward slope to the north of about 17% to 24%. Along the north edge of the terrace slopes steepen and range from about 37% to near 50%, increasing to 90% in a small area. Krazan & Associates, Inc. With Eleven Offices Serving The Western United States JenvenShelley 092-01001.dix KA No. 092-01001 January 15, 2001 Page No. 3 Field Investigation The subsurface soils in the area of the slope under consideration were explored by an engineering geologist from our office who excavated a series of hand auger test pits, maintained a log of the soils encountered, and obtained representative samples of the materials. The test pit locations are shown on the included Site Plan, Figure 2 of this report. Soil logs for the test pits are presented on Figures A-1 through A-3. Soils encountered were examined and visually classified in the field in accordance with the Unified Soil Classification System. All soil samples were returned to our laboratory for additional examination and retention. Soil Profile and Subsurface Conditions Below a sod mantle is a layer of topsoil comprised of silty, fine sand. In test pits 1 and 2 the topsoil is f about one foot in thickness while in pit 3 the thickness is slightly over six inches. In test pit 1 the topsoil is underlain by loose to medium dense, silty sand with a trace of gravel that appears to grade into an underlying medium dense sand having a variable silt content. In test pit 2 these medium dense sands directly underlie the topsoil and in test pit 3 they, the medium dense sands, are overlain and separated from the topsoil layer by about a foot and a half of silt and two inches of clean coffee -colored sand. The geologic map of the area ("Geology of the Poverty Bay Quadrangle, Washington", U.S. Geological Survey, 1961) indicates that the site area is underlain by the Salmon Springs Drift which is chiefly comprised of sand and pebble to cobble gravel but includes beds of fine sand, silt and clay. Soil Conservation Service maps of the area indicate that the site is underlain by soils of the Alderwood series, Alderwood gravelly sandy loam, 6% to 15% slopes (soil type AgC.) Soils of this series are indicated to be derived from a parent material of glacial till, typically a silty, gravelly sand similar in appearance to lean concrete. No glacial till was observed in our test pits or site slope soil exposures. Based on soils observed in our explorations and exposed in slopes around the site area, it is our opinion that the site soils closely match those indicated on the geologic map of the area than those indicated by the Soil Conservation Service mapping. S14pk Stability Based on our observations of the site slopes it is our opinion that the site slopes are stable under the present conditions and there is no evidence of slope soil movement or erosion. Site slopes, excluding Krazan & Associates, Inc. With Eleven Offices Serving The Western United States JensenShel ley 092-0I00I.doc KA No. 092-01001 January 15, 2001 Page No. 4 the area of the flattened terrace surface, generally range from about 20 to 31 degrees, 36% to 60%. Field measurements of natural slopes west of the property tend to indicate that slopes up to about 32 to 35 degrees (62% to 70%) are generally stable while those in the range of roughly 36 to 38 degrees (72% to 78%) show some localized movement. Slopes steeper than about 38 to 40 degrees (78% to 84%) generally show some degree of slope soil movement. Ground Water Ground water was observed in test pits 2 and 3 at depths of seven and six feet respectively. Zones of out -watering were also observed from the slopes west of the property. Just west of the area of proposed building, at the toe of the slope below the terrace, several areas of possible seepage were observed. However, in that our fieldwork was completed during a period of heavier rainfall these small areas of standing water may have been the result of surface runoff. It should be anticipated that ground water levels would fluctuate dependent upon seasonal precipitation, irrigation, land use, and climatic conditions, as well as other factors. There is a possibility for the development of springs or seeps originating from zones of perched water. Seismic Conditions According to the Seismic Zone Map of the United States contained in the 1997 Uniform Building Code, the project site lies within Seismic Risk Zone 3. The soils encountered in the test pits were generally medium dense to very dense below a looser near surface mantle. The overall soil profile corresponds to seismic soil profiles Sc as defined by Table 16-J of the 1997 Uniform Building Code. Soil profile Sc applies to a profile consisting predominantly of dense to very dense soils in the upper 100 feet. Conclusions and Recommendations Based on the findings of our field investigation and previous geotechnical experience in the project area, it is our opinion that the site slopes under consideration are stable under the present conditions and will remain stable following construction provided the cut slopes are properly sloped and/or supported. Therefore no landslide hazard will be developed resulting from the proposed construction. Additionally, as we understand the development plan proposed at this time, daylighting of the basement through the slope face at the anticipated elevation will reduce the slope height to about four to six feet with the remaining slope to be flattened and protected from soil movement and erosion. All areas of disturbed Krazan & Associates, Inc. With Eleven Offices Serving The Western United States JensenShelley 092-01001.Jac KA No. 092-01001 January 15, 2001 Page No. 5 soil will be replanted or otherwise protected from erosion following construction and no erosion hazard will be created. The provision of recommendations for underpinning of the existing residence and shoring for excavations is beyond the scope of this study. However, we caution that the contractor should be fully prepared to provide underpinning and shoring as necessary to protect the existing structure and provide a safe working environment for personnel. The following recommendations are provided to aid in the development of stable permanent and temporary slopes and should be incorporated into site design and construction planning. Site Preparation All areas to be cut or filled should be stripped of all sod, organic soil, existing fill and debris. It is anticipated that in most areas, a stripping depth of about a foot will be required, however, locally deeper stripping may be required to remove buried rootballs or unsuitable materials. Stripped soils, contaminated with organics or debris, should be wasted off site or used in landscape areas. Following stripping areas which are to be cut may be graded in accordance with the following recommendations. In areas to receive fill, prior to the placement of any fill, the exposed subgrade should be compacted to a firm, unyielding condition using equipment of appropriate size and type. Compaction of the stripped subgrade should be continued until field density tests show that a minimum compaction of 90% of the maximum dry density, as determined by ASTM method D-1557, has been achieved in planting, terrace, and landscape areas. In areas where the stripped surface will be use as a subgrade for constructed slopes or under building, driveway, and roadway areas compaction should be continued until a minimum of 95% of the maximum dry density is achieved. Any soft or weaving areas should be excavated and replaced with compacted structural fill. Areas which are to be filled to bring the building or pavement grades up to the desired elevation should be filled with compacted granular material free from roots, trash or other deleterious materials. We caution that the site soils are sufficiently fine grained, such that with the addition of small quantities of water they become overly saturated and are difficult or impossible to compact to the desired density. As a result, we recommend that all site grading and preparation be undertaken and completed during dry weather. If grading in building or pavement areas is necessary during wet weather, we recommend that all excavated soil be Krazan & Associates, Inc. With Eleven Offices Serving The Western United States JensenShelley 092-01001.duc KA No. 092-01001 January 15, 2001 Page No. 6 removed from the site or stockpiled and covered for use in non-structural areas. In wet weather materials used as structural fill (fill placed on slopes or under buildings or pavements) should consist of free draining sandy gravel with not more than 5.0% fines, material passing a U.S. No. 200 sieve. All imported fill material should conform to the above recommendation regardless of the weather. It is recommended that permanent cut slopes not exceed 2H:1 V (50%). Permanent fill slopes should not be steeper than 2H:1 V (50%) for fill placed in accordance with the requirements of appendix chapter 33 of the Uniform Building Code (1997 edition) or 3 to 4H:1 V (33% to 25%) for uncontrolled fills of moderate quality material. In areas where steeper slopes are required, retaining structures should be provided. In areas where fills are to be made on slopes steeper than 5H:1 V the subgrade should be benched and prepared in accordance with UBC (1997) requirements prior to fill placement. Benches should be cut at a maximum vertical height of 18 inches. It should be anticipated that, if steeply cut, the more granular near surface soils may be subject to caving, and sloughing will occur as the soils are exposed to drying. Similarly, in areas of ground water seepage sloughing should be anticipated and flatter slopes may be necessary. All temporary cuts and excavations should be sloped or shored in accordance with local, state and federal requirements. As a preliminary guideline for temporary cuts less than 15 feet in height we recommend temporary slopes be made no steeper than 1.5H:1 V for the loose to medium dense silty soils and 1H:1 V for the dense to very dense soils. For temporary cut slopes over 15 feet in height we recommend temporary slopes no steeper than 2H:1 V for the full height of the cut. Temporary slopes or excavations should be benched as required by safety regulations in effect at the time of construction. These temporary slope recommendations are for native soils and fill materials, flatter slopes may be required in wet weather or if perched water or soil conditions other than those previously described are encountered. The contractor should be aware that slope height, slope inclination, and excavation depths (including utility trench excavations) should in no case exceed those specified in local, state, or federal safety regulations; e.g., OSHA Health and Safety Standards for Excavations, 29 CFR Part 1926, or successor regulations. Such regulations are strictly enforced and, if not followed, the owner, the contractor, or the earthwork or utility subcontractors could be liable for substantial penalties. The contractor should be made responsible for the stability of all excavations and slopes during construction because he is continually on site and can observe the stability of the exposed soils. In addition, the contractor should be prepared to shore any unstable slope area and provide shoring as required by local, state, or federal laws or codes: Krazan & Associates, Inc. With Eleven Offices Serving The Western United States JenxenShelley 092-01001.dm KA No. 092-01001 January 15, 2001 Page No. 7 All structural fill ('fill below buildings, roadways or parking areas, or fill placed on slopes) should be placed on a firm, benched subgrade. Fill materials should be placed in layers approximately 8 inches in thickness, conditioned to a moisture content suitable for compaction, and compacted to 95% of the maximum dry density as determined by ASTM D-1557. In non-structural areas, i.e., planting or landscape areas, compaction requirements may be reduced to 85% of the maximum dry density. Ground Water Ground water was encountered in our investigation at the depths indicated on the soil logs. Only minor ground water related problems are anticipated if site preparation and grading work is undertaken and completed during the dry season and excavation depths are above the apparent ground water table level. We recommend that the contractor anticipate the possibility that perched groundwater may be present at elevations above that found in our excavations and be fully prepared to deal with potential ground water concerns. Consultants involved with the design of shoring, underpinning or retaining structures should be fully aware of potential ground water conditions at the site. Also, the contractor should be aware that if earthwork is performed during or soon after periods of precipitation observed ground water levels may rise. Drainage and Landscaping The ground surface should slope away from all slopes and be graded to drain to appropriate collection areas/structures. Collected water should be tight -lined to an appropriate disposal area where slopes, structures, and properties are not jeopardized by the discharged water. From a geotechnical view discharge of collected water at the beach is an acceptable means of disposal. If discharged at the beach the water should fall on an energy dissipater to lessen the potential for beach erosion. All state, federal and local regulations should be followed if the water is discharged at the beach. C n. truction Considerations In no case should excavated soils be placed on the slope or stockpiled within 20 feet of the top of any existing or excavated slope, rockery or retaining structure. Failure to comply with these guidelines may lead to destabilization of the slope. The site soils may be easily eroded by channelized water or sheet flow storni runoff. Therefore, it is recommended that all site preparation and excavation work be completed during the normally drier Krazan & Associates, Inc. With Eleven Offices Serving The Western United States knsenShelley 092-01001.Joc KA No. 092-01001 January 15, 2001 Page No. 8 portion of the year: During periods of heavy rainfall, ditching should be used to divert water away from stripped areas and visqueen should be used to cover the slopes and soil stockpiles to aid in preventing excessive surface erosion. This covering also aids in preventing infiltration of water into the unprotected soils. All disturbed soil areas and slopes should be replanted with fast-growing, deep-rooted grass, shrubs and other ground cover as soon after final grading as possible. If the vegetation is not fully established prior to the on set of wet weather, the slopes should be covered with visqueen to aid in preventing excessive erosion and water infiltration. It should be anticipated that there could be a number of additional site development or construction problems, particularly, if the earthwork has not been completed, slopes shored or supported, and the site properly protected at the onset of wet weather. It is recommended that the architect, structural engineer or their representative make periodic inspections of all excavations and slopes to provide early recognition and recommendations.
