You requested that a professionally prepared archaeological survey of the project area be conducted and a report submitted to the Department of Archaeology and Historic Preservation (DAHP) and the Tribes for review prior to ground disturbing activities. The applicant has proposed to remodel and expand a home that is at the top of a steep slope which meets the City's definition of a geologically hazardous area, and which in turn triggers environmental review under the State Environmental Policy Act (SEPA). Pursuant to WAC 197-11-908 (enclosed), the scope of the environmental review is limited to impacts associated with the geologically hazardous area. For this reason, your comments are not relevant to this SEPA review. Not withstanding this fact, we will forward your comments to the applicant so that he/she may take steps to comply with the requirements of RCW 27.44 and RCW 27.53.060 referenced in your letter. Summary Your comments are not relevant under the limited scope of this SEPA review, and do not cause us to reconsider the DNS. The Determination of Nonsignificance is now the city's final decision. Any person aggrieved of the City's final determination may file an appeal with the City Clerk by 5:00 p.m., August 22, 2011, pursuant to Federal Way Revised Code (FWRC) 14.10.060 (enclosed). SEPA appeal fees are $120.50 and are nonrefundable. If you have any questions or would like additional information, please don't hesitate to call Senior Planner Deb Barker at 253-835-2642.

The following information is provided in response to comments and concerns expressed in your letter. Geologically Hazardous Areas Development — You expressed concerns about the proposed development within the steep slope areas associated with this site, and potential impacts to the bulkhead and to your home located adjacent to the subject property. Please be advised that the conceptual review that occurs in the environmental process is not the final review for this proposal. As noted in the staff report to the environmental determination, any work on or within 25 feet of a steep slope and geologically hazardous areas is regulated by the City's adopted critical areas chapter 19.145 FWRC. Any intrusions into these areas can only be approved pursuant to FWRC 19.45 Geologically Hazardous Area Development. Geotechnical reports must provide analysis of site conditions and provide recommendations for site development and building construction. At the conclusion of the environmental process, City staff will review geotechnical considerations and reports provided with this application in order to determine if the request to intrude into steep slope and geologically hazardous areas can be approved. Geotechnical recommendations may be imposed as conditions of approval on the project, and the building permit must implement any conditions imposed by the city. Summary The city has taken your comments under advisement and has asked the applicant to respond to them. However, your comments do not cause us to reconsider the DNS, and a modification to the current Determination of Nonsignificance is not warranted at this time. The Determination of Nonsignificance is now the city's final decision.

Dupree and Ouellet: Thank you for your August 4, 2011, comment letter and the August 4, 2011, Geotechnical Report Review Letter prepared by E3RA regarding the city's environmental determination for a proposed residential addition and remodel at the above -referenced property. The following information is provided in response to your comments. SEPA Checklist Information— You expressed concern that the project State Environmental Policy Act (SEPA) checklist did not reflect all components of the project. SEPA checklists are completed by the applicant and are reviewed by city staff. Part of our review is to include updated and/or relevant information within the staff report for the environmental determination to reflect the scope of the project as known at that time. In this case, the remodel/addition proposal is reflected in the SEPA checklist, submitted drawings and reports, and the staff report. Geologically Hazardous Areas Development — You expressed concerns about development proposed within steep slope areas and potential impacts to your home located adjacent to the subject property. Please be advised that the conceptual review that occurs in the environmental process is not the final review for this proposal. As noted in the staff report on the environmental determination, work on or within 25 feet of a steep slope and geologically hazardous areas is regulated by the City's adopted critical areas chapter 19.145 FWRC. Any intrusions into these areas can only be approved pursuant to FWRC 19.45 Geologically Hazardous Area Development. Geotechnical reports must provide analysis of site conditions and provide recommendations for site development and building construction. At the conclusion of the environmental process, City staff will review geotechnical considerations and reports provided with this application, including the comments provided by your geotechnical engineer, to determine if the request to intrude into steep slope and geologically hazardous areas can be approved. Geotechnical recommendations may be imposed as conditions of approval on the project, and building permits must reflect conditions imposed by the city. Views — Your letter notes that the proposal would obstruct your southwest views of Dumas Bay and reduce your property values. The proposed remodel/addition project is vested to the City's Urban environment shoreline regulations. FWRC 15.05.050 (4)(C) states "if single-family residential development is proposed on a lot where properties adjacent to both sides of the lot are developed in Drs_ Dupree and Ouellet August 12, 2011 Page 2 of 2 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." In this case, the stringline between your property and the property west of the subject property is greater than-36 feet from the ordinary high water mark and is therefore used to define the setback. NO structure shall exceed 35 feet above average grade level as provided under FWRC 15.05.050(3)(b). Height and stringline setback will be confirmed during subsequent review of the building permit. The city is also processing a request from the shoreline substantial development permit requirements. Note that an application that is found to be exempt from shoreline substantial development permit requirement still must meet shoreline setback requirements and fully comply with FWRC 15.05.050. Summary The city has taken your comments under advisement and has asked the applicant to respond to them. However, your comments do not cause us to reconsider the Determination of Nonsignificance and a modification to the DNS is not warranted at this time. The Determination of Nonsignificance is the city's final decision.

In accordance with State Environmental Policy Act (SEPA) rules, the DNS was sent to all properties owners within 300 feet of the subject property as well as specific state agencies for comment. The City received two comment letters before the August 8, 2011 comment deadline, as well as a letter from the Department of Archaeology and Historic Preservation on August 10, 2011. The letters expressed concerns about potential impacts to adjacent properties that may result during the removal of the septic system, as well as potential impacts resulting from pin pile installation, view blockage, the existing condition of the retaining wall and archaeological site protections. Copies of the letters are enclosed. The submitted comments appear valid, and the City will respond to each of the letters. However, the comments do not appear to warrant reconsideration of the Determination of Nonsignificance. Your timely written response to the comment letters is requested. As of this date, the SEPA appeal period has commenced and it expires on August 22, 2011. Please do not hesitate to contact me if you have any questions about this letter.

We have owned the neighboring property to the south for over ten years at 3128 SW 302nd Place. Due to the sizable amount of work being proposed on a hazardous slope area & the relocation of the house & deck closer to the water we are concerned about the structural integrity of the existing bulkhead. The current bulkhead is quite old & has suffered sinkholes & patch work repair over the years. We feel it would be prudent to complete a thorough examination of the bulkhead to assess if it is capable of withstanding the increased stress being placed on the slope by the larger, proposed structure. Secondly, we are worried about the structural impact on our property due to the removal of the current drain field & replacement fill. This process exposes our property to possible structural settling during & after construction of the remodel. The seasonal timing of work on the slope concerning the weather is also an issue as rain & runoff would potentially make the process more unstable. Heavy equipment disturbing the slope may impact our neighboring properties. A thorough geological survey of affected property's before, during & after the project would address our concerns of structural settling. We look forward to finding solutions to these concerns with the city of Federal Way. Sincerely, Roger & Jana Goodwin David W. Dupree, MD, MBA and Lyne M.

And Patrick Doherty Dear Ms. Barker, Mr. Conlen, Mr. Doherty: CITY OF FEDERAL WA', C®S J This letter is to express concerns about the environmental determination of non -significance issued on July 23, 2011 with regard to the Bradshaw/Harkness Residential Remodel/Addition (Federal Way File No: 11-101539-00-SE). My wife and I are the owners of the residence at 3120 SW 302❑d Place immediately upslope of the proposed Bradshaw/Harkness project. We have reviewed the documents submitted by the applicants to the city of Federal Way and have several areas of concern. 1. Question 11 under Section A of the SEPA environmental checklist submitted by the applicant described a pro posed project of 1200 square feet total addition to the main residence comprised of 400 s.f. at the basement area and 800 s.f. at the main floor and a 480 s.f. detached garage (1680 s.f. total project area). The plans submitted by the applicant, however, represent additions of 785 s.f. on the main floor and 1141 s.f. (1926 s.f. total) on the basement level as well as a 700 s.f. deck which was not previously mentioned on the SEPA checklist (Total project area 2826 s.f.). One would assume that there is a requirement for the SEPA checklist to accurately reflect the project for which the determination of non significance is sought. 2. Under Section B question 1, b. regarding surface indications of unstable soils in the immediate vicinity. This site falls into the geologically hazardous area as described by the Federal Way Shoreline Master Program and new construction in this zone should be undertaken with great caution. Our house demonstrates unstable soils by movement toward the subject property which is demonstrated by cracking and settling of concrete in place on sidewalks, foundations, and patios up slope and directly adjacent to the subject property. This settling has required drainage modifications and repairs to the house to control and appropriately channel surface water runoff, repeated concrete replacement, slabjack leveling of concrete panels, repair of rockeries, and filling of cracks and separations at the junction of the house and concrete sidewalks and is a constant maintenance issue. Earthquakes, predictably, exacerbate this movement. We have evaluated the geotechnical findings submitted with this application along with the engineer's reports and we are most concerned with the removal of the existing septic tank and down slope drain field which will be replaced with fill and compacted. We did not see a graphic depiction as to the exact location of this field so the exact portion of the slope to be excavated remains a mystery. We are very worried that disturbance of the existing slope to such a great degree (removal of existing drain field, fill to replace the lost volume, and compaction requiring multiple vibration inducing hammer strikes will induce upslope motion and markedly increase slide probability on our adjoining property. The subject hillside is essentially loose sand over clay and a definite landslide hazard. Given the level of movement we have seen in the past with even minor earthquakes, the thought of a compacting device creating multiple mini -quakes immediately down slope of our home of 21 years is very worrisome. This aspect of the construction project has not been addressed adequately in either the geo-tech survey or the engineer's report. E3RA August 4, 2011 T11075 David Dupree 3120 SW 302nd Place Federal Way, WA 98023 Subject: Geotechnical Report Review Letter 3124 SW 302nd Place Federal Way, Washington Dear Mr. Dupree: PO Box 44890 Tacoma WA 98444 253-537-9400 253-537-9401 fax o -yo H106 RECEIVED CV OF \N A'(. C3S E3RA is pleased to submit this Geotechnical Report Review Letter for the project site located at 3124 SW 302❑d Place adjacent to your property at 3120 SW 302nd Place in Federal Way, Washington. The purpose of our review is to address the impact the construction activity may have on your property given the geologic conditions described at the site. We reviewed a Geotechnical Report, Geotechnical Engineering Investigation Proposed Renovation Work for the property at 3124 SW 302"d Place, Federal Way, Washington, dated April 7, 2011. The report was provided by N.L. Olson and Associates, Inc. Our scope of work is limited to surface observations, geotechnical research, and letter preparation. This letter has been prepared for the exclusive use of Mr. Dupree and his consultants, for specific application to this project, in accordance with generally accepted geotechnical practice. PROJECT AND SITE DESCRIPTION The project site is located on the south bank of the Puget Sound. The water front lot is trapezoidal and encompasses about 0.86 acres. As described in the report, the site slopes down to the north-northwest ranging from about 15 to 80 percent. The relief is on the order of 30 feet from the crest to the toe of the slope. The geology is described in the report as about 25 feet of loose to medium dense sand overlying stiff to hard silt/clay. Plans call for an addition to the north side of existing single family residence. The addition incorporates an 1141 square foot daylight basement with a second story of approximately 785 square feet. In addition, a wood deck with approximately 700 square feet will be added to the northern side of the addition. We understand that both the addition and the deck will be supported on pin piles. Also mentioned within the report, is a septic drain field located northwest of the existing home and south of a rock wall. Based on our conversations with you, we understand that the septic tank will be exhumed and the drain field(s) will be removed and backfilled in order to accommodate the new construction. Ultimately, the new addition will utilize the existing municipal sewer system. We visited the site on August 1, 2011 and our site reconnaissance and observations indicate that conditions described in the report are accurate and that the recommendations are in accordance with generally accepted geotechnical practice There is extensive use of pin piling in the plans for the new structure as well. While the risk of pin piling activity is thought to be less than the compacting which is envisioned, the risk of movement of the up slope structures still exists. There is also mention in the plans of tree and root system removal to be carried out. Which root systems are to be affected is not specified. Previous tree removal has left extensive living root systems which stabilize the slope at some of the steepest parts of the slope within 2 to 5 feet of the property line. One would assume that such activity would require fill replacement and compaction similar to that required for the drain field rehabilitation. Disturbance of these root systems without appropriate upslope shoring would almost certainly lead to up slope instability and increase the potential for slide activity. 3. Under Section 10 question a of the SEPA checklist regard alteration of views: This project would significantly obstruct the southwest view of Dumas Bay from our property and reduce our property value. We believe that the project as currently envisioned and planned falls short of providing adequate mitigation of serious potential risks to our property that could be induced by the project. For these reasons, we believe the project should not proceed until adequate evaluation and mitigation of the risks and potential impacts to our property can be accomplished. Sincerely, cv David W. Dupree, MD, MBA A-C-C� Lyne M. Ouellet, MD August 4, 2011 ORA, Inc. Dupree Geotechnical Report Review Letter CONCLUSIONS AND RECOMMENDATIONS Based on our observations of the surface and subsurface conditions, as well as our review of the Geotechnical Engineering Report provided by others, we are in general agreement with the recommendations for foundation support provided by the installation of pin piles. E3RA's concern is with the removal of the current septic system and the subsequent backfill operations. As the geologic conditions are prone to movement under normal, non -construction related activity, we are concerned that the removal of this septic system and the vibrations associated with compacting the backfill may have a detrimental effect on your property, which is directly adjacent and upslope of this construction project. Based on the possibility of movement upslope, caused by the vibrations associated with mechanically compacting fill materials, we recommend that the Dupree residence be surveyed by a licensed professional surveyor prior to, during and after the completion of the septic removal and backfill operations. In the event of any upslope movement, this operation should be suspended until such time as the Dupree residence has been shored and properly supported. CLOSURE The conclusions and recommendations presented in this letter are based, in part, on our interpretations and assumptions regarding subsurface conditions; therefore, if variations in the site conditions are observed at a later time, we may need to modify this report to reflect those changes.

The area has a high potential for archaeological resources. At least two precontact archaeological sites have been identified in the Lakota Beach area on landforms similar to that of the project area. These sites are within approximately 730 feet of the proposed project area. Please be aware that archaeological sites are protected from knowing disturbance on both public and private lands in Washington States. Both RCW 27.44 and RCW 27.53.060 require that a person obtain a permit from our Department before excavating, removing, or altering Native American human remains or archaeological resources in Washington. Failure to obtain a permit is punishable by civil fines and other penalties under RCW 27.53.095, and by criminal prosecution under RCW 27.53.090. Chapter 27.53.095 RCW allows the Department of Archaeology and Historic Preservation to issue civil penalties for the violation of this statute in an amount up to five thousand dollars, in addition to site restoration costs and investigative costs. Also, these remedies do not prevent concerned tribes from undertaking civil action in state or federal court, or law enforcement agencies from undertaking criminal investigation or prosecution. Chapter 27.44.050 RCW allows the affected Indian Tribe to undertake civil action apart from any criminal prosecution if burials are disturbed. Identification of cultural resources during construction is not a recommended detection method because inadvertent discoveries often result in costly construction delays and damage to the resource. Therefore, we request a professional archaeological survey of the project area be conducted and a report be submitted to DAHP and the Tribes for review prior to ground disturbing activities We also recommend consultation with the concerned Tribes' cultural committees and staff regarding cultural resource issues. Finally, please note that effective Nov. 2, 2009, DAHP requires that all cultural resource reports be submitted in PDF format on a labeled CD along with an unbound paper copy. Thank you for the opportunity to comment on this project and we look forward to receiving the survey report.

NLO's Response: NLO understands that in lieu of rain garden/cistern systems that would infiltrate into the slope area between the shoreline and residence. NLO has recommended that the collected runoff should be tight lined to the bottom of the bulkhead or staircase. This method of stormwater disposal in our opinion is acceptable. However, such disposal systems should comply with all applicable regulations and the pipes should discharge into a manifold -type structure or into an energy dissipater such as a pad of crushed rock to minimize erosion. City Of Federal Way Comment (2) May 23, 2011: Portions of the addition are proposed to be constructed over the existing septic system which will be abandoned. Please provide recommendations for this abandonment and subsequent construction. Response: NLO recommends that a professional who specializes and licensed in septic system design should also be consulted to assist with the septic system removal. The person consulted for the septic system removal will need to determine the extent and depth of the drain field area to be removed and may require their assistance to be on site during drain field clean up operations. Once the area has been determined clean and signed off by the person consulted for the septic system removal, the subsequent excavation can be brought back up to the desired construction elevation with structural fill or general fill. NLO has also provided recommendations for backfilling the drain field area below. RESUBMITTED JUN 2 8 2011 CITY OF FEDERAL WAY CDS P O.

However, deeper excavations will be required to remove large tree root system, existing fill, foundations, septic tanks and associated drainfields, or pockets of unsuitable soils. Stripped soils, contaminated with organics or debris, should be wasted off site. Following site stripping, and prior to fill placement, the exposed subgrade should be compacted to a firm, unyielding condition using vibratory equipment of appropriate size and type. Compaction of the stripped subgrade should be continued until field density tests show that a minimum compaction of 95% of the maximum dry density, as determined by ASTM method D-1557, has been achieved in all fill, and building the areas. 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 recommend that all site grading and preparation be undertaken and completed during dry weather with on site soils. If grading in building, or pavement areas is necessary during wet weather, we recommend that all excavated soil be removed from the site or set aside in covered stockpiles, and structural fill as defined below for the purposes of grading. Structural fill is defined as compacted fill placed under buildings, foundations or along grade beams that consist of free draining gravelly sand having a maximum size of 1-1/2 inches and with not more than 5.0% fines, material passing a U.S. No. 200 sieve. All imported fill material should conform to the above recommendations regardless of the weather. All structural fill should be placed on a firm, properly prepared subgrade. Structural fill should be placed in 8 inch thick layers, conditioned to a moisture content suitable for compaction, and compacted to 95% of the maximum dry density as determined by ASTM D-1557. General fill consist of on -site granular soils such as sand with a fines content greater 5 percent. This material can be used in lieu of structural fill if compaction can be achieved typically during the dryer time of the year April through October. If fill is to be placed between November and March, NLO strongly recommends utilizing structural fill material. General fill shall be placed on a firm, properly prepared subgrade. The fill material 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. Note: On -site fill material, structural fill, and materials associated with the placement of the fill slope or for backfill within the proposed drain field / septic tank removal area be approved by the geotechnical engineer prior to construction. City Of Federal flay Comment 43f May 23, 2011: The Boundary and Topographic Survey prepared by Centre Pointe Surveying shows several rock walls that will be covered by the building addition and/or decking. Discuss the impact, if any, removal of these structures will have on the slopes, and detail construction recommendations, as appropriate. Response: In our opinion, the rock walls removed with in or below the proposed building or deck areas should have minimal impact on the slope in the form of slope or soil instability to this or adjacent properties. However, NLO is recommending that the slope presently supported by the rock wall that are P.O.

Please note that the rock wall along the observed alignment is less than five (5) feet. Therefore, NLO recommends that the large basal rock comprising the rock wall should be removed in 10 to 15 foot long sections and the slope flattened to the desired gradient along that section. The rock wall removed in this manner should preclude any slope instability concerns. It is recommended that permanent cut slopes or fill slopes should not exceed 21-1:1 V (50 percent). In areas where steeper slopes are required, retaining structures should be provided. It should be anticipated that, if steeply cut, the near surface soils may be subject to caving, and sloughing will occur as the soils are exposed to drying. All temporary cuts and excavations should be sloped or shored in accordance with local, state and federal requirements. It is our opinion that fill slopes may be constructed, provided the fill is placed and compacted in a manner that is consistent with recommendations presented in the structural fill or general fill discussed in the previous section of this letter. The fill placed along fill slope areas should be placed in horizontal lifts not exceeding 8 inches loose thickness, moisture conditioned as necessary and compacted to a minimum of 95 percent of maximum dry density based on ASTM Test Method D1557. Recommendations for fill placement on slopes are provided solely as a service to our client. NLO, under no circumstances, assumes liability for the site with regard to safety or other construction activities directed by the contractor.

An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS This environmental checklist asks you to describe some basic information about our proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply." Complete answers to questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NON -PROJECT PROPOSALS Complete this checklist for non -project proposals, even though questions may be answered "does not apply." In addition, complete the Supplemental Sheet for Non -Project Actions. For non -project actions, the refere site" should be read as "proposal," ecklist to the rds " t, and "affected ge phic are L � " "applicant," and "property or " respectively.

SUPPLEMENTAL SHEET FOR NON -PROJECT ACTIONS Because these questions are very general, it may be helpful to read them in conjunction with the list of the elements of the environment. When answering these questions, be aware of the proposal, of the types of activities likely to result from the proposal, and if they are likely to affect the item at a greater intensity or at a faster rate than if the proposal were not implemented. Respond briefly and in general terms. 1. How would the proposal be likely to increase discharge to water; emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise? Storm runoff will be moderately greater than existing but controlled. No substantial air emissions, toxic or hazardous substances or noise will be produced beyond typical residential impact. Existing wood burning fire place will be removed. Proposed measures to avoid or reduce such increases: Most impacts may be reduced through new building systems updated from existing 1950s technology. Proposed fire place will be direct vent gas log. 2. How would the proposal be likely to affect plants, animals, fish, or m S e life?\ On -site plant life will be improved by removal of invasive she ies and native planting for soils stability. Proposal is designed for reduced impact and low energy use relative to typical residential construction. Natural shoreline condition will be maintained. •. Proposed measures to protect or conserve plants, animals, fish, orma ute: Natural plantings along with storm water control for low -impact discharge to maintain a natural condition to the largest extent possible 4. 3. How would the proposal be likely to deplete energy of natural resources? Typical residential energy use and consumption of materials will be mitigated through 'green' product choices, use of solar energy, and other design features to reduce environmental impact and energy usage. Proposed measures to protect or conserve energy and natural resources: Demolition will include salvage of usable materials. Energy sources will include passive solar & ground source heat pump. Building envelope will be insulated and sealed beyond code minimum. Storm runoff will be controlled with rain garden and/or cistern. Additional green strategies will be utilized including re -used, natural and non-voc materials. 4. How would the proposal be likely to use or affect environmentally critical areas or areas designated (or eligible or under study) for governmental protection; such as parks, wilderness, wild and scenic rivers, threatened or endangered species habitat, historic or cultural sites, wetlands, floodplains, or prime farmlands?

We have determined that the proposal will not have a probable significant adverse impact on the environment. As a result, an Environmental Impact Statement (EIS) is not required to comply with the State Environmental Policy Act (SEPA). A 14-day comment period is required by the SEPA rules (WAC 197-11-340). A notice inviting comments will be published in the Federal Way Mirror on July 23, 2011. At the end of the comment period, the department will decide if the Determination of Nonsignificance (DNS) should be withdrawn, modified, or issued as proposed. All final determinations may be appealed within 14 days following the comment deadline. No licenses, permits, or approvals will be issued until completion of the appeal period. Our decision not to require an EIS does not mean that the license, permit, or approval you are seeking from the City has been granted. Approval or denial of the proposal will be made by the appropriate administrative or legislative body vested with that authority. The environmental record is considered by the decision maker(s) and conditions will be imposed to reduce identified environmental impacts, as long as the conditions are based on adopted and designated City policy. After a final decision has been made on your proposal (i.e., after a permit has been issued or City Council action taken, as applicable), you may, but are not required to, publish a Notice of Action as set forth in RCW 43.21 C.075. The Notice of Action sets forth a time period after which no legal challenges regarding the proposal's compliance with SEPA can be made. A copy of the Notice of Action form and copies of RCW 43.21C.080 and WAC 197-11-680 providing instructions for giving this notice are available from the Community and Economic Development Department.

Technical reports and attachments referenced herein and in the environmental checklist may not be attached to all copies of this evaluation. Copies of exhibits, reports, attachments, or other documents may be reviewed and/or obtained by contacting the Department of Community and Economic Development, 33325 8d` Avenue South, Federal Way, WA 98003, 253-835-2607. SUMMARY OF PROPOSED ACTION The applicant has applied to construct additions to an existing "basement rambler" style single-family home on a parcel adjacent to Puget Sound in Federal Way. According to the City's environmentally sensitive area map, the subject site is located within erosion hazard soils areas and contains slopes that exceed 40 percent. Work proposed within these areas is subject to environmental review under the Federal Way Revised Code (FWRC). The subject site is bordered on the east, south, and west by existing single-family residences, with Puget Sound to the north. Vehicular access to the property is provided off SW 302A Place. According to submitted plans, the applicant proposes to build a two level addition north of the existing house. The new 785 square foot main floor and the new 1,141 square foot basement additions will tie into the existing house levels along with a new 700 square foot deck that will cantilever over the existing hillside; a smaller 42 square foot addition will be added to the south side of the main level; a future 480 square foot detached garage will be constructed south of the house; and the existing septic system will be removed when public sewer is extended to the house.

I.D. 57708 Page 1 of 6 File 11-101539-SE STAFF EVALUATION OF ENVIRONMENTAL CHECKLIST Following are staff responses to the elements of the environmental checklist (enclosed) indicating whether or not City, staff concurs with the applicant's response to the checklist item, or staff clarification or amendment of the response. A. BACKGROUND 1-5. Concur with the checklist. B. 6-7 Permit review for the residential addition consists of State Environmental Policy Act (SEPA) review, issuance of SEPA determination, a 14-day comment period, a 14-day appeal period, a shoreline exemption request, a request to intrude into critical area buffers, building permit review, and building permit issuance. To date, a building permit has not been submitted. 8. The following specialized studies and plans were prepared and submitted by the applicant: • SEPA checklist prepared by David Falls dated April 22, 2011, revised June 27, 2011; • Geotechnical Engineering Investigation Proposed Renovation Work, prepared by N.L. Olson and Associates, Inc. April 2011, with a June 21, 2011, addendum; • Boundary and Topographic Survey prepared by Centre Pointe Surveying, Inc. November 7, 2006; • FEMA National Flood Insurance Program Elevation Certificate prepared by Dale Oaks, PLS, April 20, 2011; and • Site plan, section and details prepared by Fall Architectural Studio April 22, 2011; revised June 24, 2011. 9. Concur with the checklist. 10, As noted above, shoreline exemption permit #11-101540-SH has been submitted with this request and is under review concurrently with the environmental application. 11-12. Concur with the checklist. WAC 197-11-908 authorizes SEPA based review of additions to single-family dwelling units only when located within critical areas, and then only for specific impacts to those critical areas. In this case, the staff evaluation has been prepared to address issues relating only to critical areas. The City will address storm drainage design issues in their review of the geologically hazardous areas intrusion request, and will address archaeological protections in their review of the shoreline exemption request. ENVIRONMENTAL ELEMENTS 1. Earth City of Federal Way Environmentally Sensitive Areas Map reveals that the site is located in a critical area relative to erosion hazards, and slopes leading from the house to Puget Sound are in excess of 40 percent. The 1973 King County soils report classifies site soils as Indianola (InC), characterized loamy fine sand with 4-15% slopes, and Coastal Beach (CB). The subsurface exploration conducted by N.L. Olson and Associates, Inc., found loose poorly graded sand and poorly graded sand with silt on the site. Subsurface water was observed 5 feet and 19 feet below ground surface. No actual work will occur on the steep slopes or to existing rockeries in these slopes; although, the new deck will be cantilevered over the uppermost rockery and slope. a-c. Bradhshaw/Harkness Staff Evaluation for Environmental Review Doe. I.D. 57708 Page 2 of 6 File 11-101539-SE d-e. According to the April 2011 Geotechnical Engineering Investigation Proposed Renovation Work report prepared by N.L. Olson and Associates, at the time of their 2010 slope reconnaissance, the slope area between the shoreline and the residence appeared stable. Their slope stability analysis found an adequate factor of safety for the proposed addition, and the new deck was not anticipated to adversely affect the slope area. Of concern was the potential for different settlement between the new portions of the house and the old. The Geotechnical Engineering Investigation Proposed Renovation Work report contains specific recommendations to address these concerns, including that floor slabs in the area of the addition and the new deck should be structurally supported on pin piles, and axial anchor support provided for the new addition and the wood deck. f. Concur with the checklist. The Temporary Erosion and Sedimentation Control (TESL) plan will be reviewed with the intrusions into critical areas. Recommendations contained in the Geotechnical Engineering Investigation Proposed Renovation Work report and addendum will be verified including the recommendation that all site preparation and excavation work be completed during the normally drier portion of the year, and all slopes be replanted with fast growing deep rooted grass, shrubs, and other groundcover as soon after final grading as possible. g. Concur with the checklist. The FWRC permits up to 60 percent of the site located in this zoning district to be impervious. h. Development activities and land surface modifications on or within 25 feet of a steep slope and geologically hazardous areas are regulated by the City's adopted critical areas chapter 19.145 FWRC. Under FWRC 19.160, the geotechnical report is intended to provide analysis of site conditions and provide recommendations for site development and building construction. The report includes discussion on slope reconnaissance; seismic design criteria; and slope stability, and contains recommendations for axial support systems, structural fill, general fill, floor slabs, temporary slopes, surface runoff, and perched groundwater, and erosion control. City staff will review the Geotechnical Engineering Investigation Proposed Renovation Work report, prepared by N.L. Olson and Associates, April, 2011, with the June 2011 addendum, in conjunction with the steep slope and geologically hazardous areas intrusion review. 2. Air a-c Concur with the checklist. Compliance with local, state, and federal air quality standards is expected to provide sufficient mitigation of potential impacts. 3. Water a. Surface — 1-5) The Federal Way Wetland Inventory does not reveal any wetlands, streams, or 100- year floodplains within 100 feet of the site. The subject site is located on Puget Sound. The existing house as well as all additions will be located approximately 55 feet or more above the Ordinary High Water Mark (OHWM). The developed portion of the subject property is located in Zone `X,' which is above any designated flood hazard area as identified by the Federal Insurance Administration flood insurance rate map (FIRM). The shoreline portions of the site are located in Zone `A,' which is subject to flooding. The applicant submitted an FEMA National Bradhshaw/Harkmess Staff Evaluation for Environmental Review Doc. I.D. 57708 Page 3 of 6 File 11-101539-SE Flood Insurance Program Elevation Certificate prepared by Dale Oaks, Professional Land Surveyor, April 20, 2011. The elevation certificate meets the requirement to obtain an elevation certificate establishing the location for the house and addition as above the Base Flood Elevation as required in FWRC 19.142. 6) The applicant proposes to discharge roof runoff from the addition and the existing roof onto the Puget Sound shoreline. See section 3.c (below) for details. b. Ground 1-2) Concur with the checklist. C. Water Runoff (including stormwater) 1) Roof runoff is currently directed into an underground system but it is not known where the system discharges. The N.L. Olson and Associates Inc. geotechnical report addendum states that new and existing roof runoff is proposed to be collected and discharged in a tight -lined system to the bottom of the existing shoreline bulkhead, or onto the existing staircase leading to the beach. However, the concrete stairway was not designed as a stormwater disposal or dissipation system and is in a dilapidated condition. For these reasons, staff has concerns with the proposed discharge of roof downspout runoff onto the beach stairs. Additional review of this component will be conducted during geotech intrusion review. 2) Concur with the checklist. d. Storm drainage systems are required to be designed in accordance with the King County Surface Water Design Manual (KCSWDM) and the City's engineering standards. Recommendations contained in the reports prepared by N/L/ Olson and Associates Inc, shall be incorporated into construction permits for the project, and will be reviewed by the Public Works Department during the geotechnical intrusion review and the building permit process. 4. Plants a-d. Concur with the checklist. Separate review of a planting plan for steep slope and or exposed soils will be required prior to issuance of a building permit. The plan must be prepared by a qualified landscape professional and must be vetted by the geotechnical consultant. 5. Animals a-d. Concur with the checklist. The site is part of the Pacific Flyway. 6. Energy and Natural Resources a-c. Concur with the checklist. 7. Environmental Health a-b. Concur with the checklist. 8. Land and Shoreline Use a-f. Concur with the checklist. The comprehensive plan designation is single-family high - density. Bradhshaw/Harlmess Staff Evaluation for Environmental Review Doc. I.D. 57708 Page 4 of 6 File 11-101539-SE g. The subject site is located in the "Urban" shoreline designation, which is intended to ensure optimum utilization of the shorelines of the state by permitting intensive use and by managing development so that it enhances and maintains the shorelines of the state for multiple uses. h. The subject property is located in an erosion hazard area as depicted on the Federal Way sensitive areas map, contains steep slope hazard areas with slopes over 40 percent, and is located on the Puget Sound shoreline. The geotechnical report included discussion on slope reconnaissance, seismic design criteria, and slope stability, and contained recommendations for axial support systems: structural fill, general fill, floor slabs, temporary slopes, surface runoff and perched groundwater, and erosion control. i-1. Concur with the checklist. 9. Housing a --c. Concur with the checklist. An accessory dwelling unit (ADU) requires separate land use approval and related building permits. These applications are subject to applicable standards of FWRC 19.265.020; however, an ADU is not subject to environmental review. 10. Aesthetics a-c. Concur with the checklist. 11. -Light and Glare a-d. Concur with the checklist. 12. Recreation a-c. The nearest designated and informal recreation activity is located at the Poverty Bay Park approximately '/z mile east of the site, and at Dumas Bay Centre, 1/4 mile west of the site. 13. Historic and Cultural Preservation a-c. The Washington State Department of Archeology and Historic Preservation has record of an archeological site in the Lakota Beach area. In addition to the recorded site, a cultural resource site was recently found in the Lakota Beach area. The subject property is located along the shoreline of Puget Sound, with a high bank shoreline, and is in the general vicinity to the two above -referenced cultural resource sites. There is a potential for the presence of historic cultural resources at the site, based on the presence of other known cultural resources in the nearby vicinity, which will be reviewed in conjunction with the shoreline exemption request. 14. Transportation a-g Concur with the checklist. The construction of the new garage will establish three parking stalls at the subject property, in excess of the two parking stalls required for the single- family house. 15. Public Services a-b. Concur with the checklist. 16. Utilities a-b. Concur with the checklist. Prior to issuance of any building permits, information about the removal of the existing septic tank and drain field must be included on the plans.

An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS This environmental checklist asks you to describe some basic information about our proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply." Complete answers to questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NON -PROJECT PROPOSALS Complete this checklist for non -project proposals, even though questions may be answered "does not apply." In addition, complete the Supplemental Sheet for Non -Project Actions. For non -project actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respec ESUBMI17ED JUN 2 8 2011 CITY OF FEDERAL WAY CDS Bulletin #050 — January 1, 2011 Page 1 of 18 k:\Handouts\Environmental Checklist A.

The applications were submitted for proposed additions to a residential structure that is located within an environmentally sensitive area and is on Puget Sound at 3124 SW 302°d Place in Federal Way. According to code regulations, upon receipt of an application the City has 28 days to determine whether all information and documentation required for a complete environmental application has been submitted. NOTICE OF COMPLETE APPLICATION Please consider this letter as a Letter of Complete Application. Pursuant to the Federal Way Revised Code (FWRC), the application submitted on April 22, 2011, is deemed to be complete based on a review of your submittal relative to those requirements as set out in the Development Requirements Checklist. A 90-day time line for reviewing the project has started, and will be stopped at any time that the City requests additional information. You will be informed of the status of the 90-day time line when you are notified in writing that additional information is needed, as noted below. ADDITIONAL INFORMATION REQUESTED The following items were identified in reviewing the application for completeness. With this request for additional information, the 90-day maximum review time frame is suspended with eleven' of the 90 days used, and it will be restarted within 14 days of the date of your complete response to this request. 1. SEPA Checklist — Please revise the SEPA checklist to address the following comments. This information is necessary for an environmental determination. B.3.b.1 — Revise the checklist to state that there currently is a septic system in place, but that it is proposed to be abandoned, and sewer extended onto the property. ' The 90-day review clock began on May 12, 2011, with the Development Review Committee (DRC) confirmation of the complete application Mr_ David Fall May 23, 2011 Page 2 13.3.c. — The checklist states that roof runoff will be tight lined to a cistern or rain garden for controlled release into native soils. Verify that the Geotechnical Engineering Investigation Proposed Renovation Work prepared by N.L. Olson & Associates, dated April 2011 addresses this proposed action. Include any recommended mitigation. B.4.b — The checklist states that no vegetation will be removed and further states that the slopes will be improved with native plants. Revise the checklist to state that portions of the site will be cleared of vegetation to install the proposed addition as well as the proposed deck. List the size of the area cleared for the addition/deck. Note that the planting of any steep slope vegetation shall be based on a landscape plan prepared by a qualified professional and approved by the City (see item #4 below). 13.1 6.b — Revise the checklist to state that there currently is a septic system in place, but that it is proposed to be abandoned, and sewer is proposed to be extended to the property. The house will be connected to a grinder pump via a 4" PVC pipe, which will extend to the property line via a 1- 1/4 inch HDPE. List the septic system abandonment method. Geotechnical Report — The report Geotechnical Engineering Investigation Proposed Renovation Work prepared by N.L. Olson & Associates, dated April 2011, was submitted to address project components. The report must be revised to address the following items in order for the environmental determination to be issued: Discuss the proposed roof runoff tight lined to rain garden/cistern systems, and provide recommendations as appropriate. Portions of the addition are proposed to be constructed over the existing septic system which will be abandoned. Please provide recommendations for this abandonment and subsequent construction. The Boundary and Topographic Survey prepared by Centre Pointe Surveying shows several rock walls that will be covered by the building addition and/or decking. Discuss the impact, if any, removal of these structures will have on the slopes, and detail construction recommendations, as appropriate. Please be advised that under FWRC 19.150.030 Basis for Determination, the City may require that the City's Geotechnical consultant review the Geotechnical Engineering Investigation. Their review would be funded by the applicant Should the city determine that the project requires peer review, you will be advised of the consultant's estimated review cost. 3. Nonconforming Setback — It appears that the south-east portion of the existing house shown on the Boundary and Topographic Survey prepared by Centre Pointe Surveying, Inc. is less than five feet from the side property line. The required side yard setback for a residential structure located in the RS zoning district is five feet per FWRC 19.200.010 Detached Dwelling Unit. Please confirm the side yard setbacks for the existing and proposed structure. If the house is less than five feet from the side property line, the provisions of FWRC l 9.30.090 (1)(c)(iii) Nonconformance - Increase in gross floor area shall apply. This code states that existing nonconformities may remain and continue so long as the existing nonconformities are not being increased or expanded in any way. According to site plans, the south-east portion of the house is proposed to be expanded. If it is found that the house is set back less than five feet from the side 11-101539 Doc, 1. D. 57712 Mr. David Fall May 23, 2011 Page 3 property line, this particular area of building addition would expand a nonconforming setback condition and can not be approved. This area of expansion could only be approved if it is fully outside of the five-foot side yard setback. Alternatively, a Boundary Line Adjustment (BLA) to relocate the property Iine away from the nonconforming structure could be sought? This potential nonconforming condition will not impact the City's environmental decision on the proposal. However, future building permits for the residential addition will not be issued if the addition is located in a required building setback. 4. Steep Slope Planting — Prior to issuance of a building permit for the addition, a planting plan with steep slope planting recommendations shall be submitted to the city for review and approval. The plan must be prepared by a qualified landscape professional and must be vetted by the Geotechnical consultant. SHORELINE EXEMPTION The City will process the Shoreline Exemption request concurrently with the environmental process. NEXT STEPS Please note that items #1 and #2 above must be addressed before project review can proceed and an environmental determination made. A 14-day comment period followed by a 14-day appeal period will follow the environmental determination. Construction permits can be submitted at any time. However, construction permits will not be issued until the environmental process has concluded, nonconforming setback issues are resolved, and a planting plan is submitted and approved (items #3 and #4 above).

A portion of the existing basement rambler structure currently lies partially within the 25 foot setback from existing sloped grades that are defined as a Landslide Hazard. The sloping gradients are minimal but some slope areas beyond the proposed work are > 40%. Our proposal is to expand and remodel the existing 1950s structure and includes the addition of building and deck footprint on the water side no further than the 'string line' connecting existing adjacent neighboring structure. The lot is narrow and the limited width of the lot forces additional footprint length of the house both water ward and land ward. This is the only reasonable alternative that will allow the owners to achieve their architectural goals for improved and updated interior spaces and access to view lines otherwise obstructed by neighboring structures. Our proposed project will not lead to any increased slide, seismic or erosion hazards as structural design and construction will follow recommendations by N.L. Olson and Associates, Inc. These include axial foundation support, fill requirements, temporary slope guidelines, surface runoff mitigation, and erosion control. Thank you!

We will provide a professional archaeological survey of our project area as requested by the DAHP. We will hire this service to be certain that any potential cultural issues are resolved prior to building permit submittal and we will consult with concerned Tribes based on findings of the survey before building permit submittal. I hope this strategy will satisfy DAHP, Tribe and City of Federal Way concerns regarding our proposed project. Thank you! Yours truly, David J.

Port Orchard, WA Subject: Information Review Bradshaw/Harkness Residential Addition 3124 SW 302nd Place Federal Way, WA 98023-2342 NLO has reviewed the follow document "Septic System Abandonment Letter, 3124 SW 302"d Place, Federal Way, WA, Prepared by Babbit Septic Design, Inc." Dated January 9, 2012, which Provides criteria for abandonment of existing septic system per: • WAC 246-272A-0300- abandonment ■ King County Title 13.04.054 - Abandonment NLO is concurs with provided criteria for existing septic system abandonment. King County Title 13.04,054 - abandonment recommends the use of pea gravel to backfill voids such as the septic tank. In NLO's opinion, pea gravel will minimize the need for compaction equipment and address the neighbor's concern with mechanical vibration from heavy compaction equipment. Pea gravel does not require compaction. Should you have any questions or concerns, which have not been addressed, or if we may be of additional assistance, please call our office.

Fall has requested a cultural resource assessment of 0.84 acre parcel (parcel no. 0121039058) located in Federal Way, Washington. This parcel is owned by Ms_ Barbara Bradshaw and Mr. Ron Harkness and hosts one existing structure, a single-family four -bedroom dwelling constructed in 1952. The Bradshaw -Harkness Addition Project ("the Project") will construct a 1200 square foot addition to the wood -framed rambler style home and includes construction of a 480 square foot detached wood -framed garage. Construction also includes the establishment of an improved stormwater collection system that will direct roof runoff into pipes that route into a manifold structure where water is discharged into a dissipater system located adjacent to the existing bulkhead/stairway. The Washington State Department of Archaeology (DAHP) was contacted regarding the project and recommended that a cultural resource survey be completed prior to any construction activities. This project falls under the auspices of Governor's Executive Order 05-05 (EO 05-05), and the DAHP is responsible for ensuring compliance with EO 05-05. This Scope of Work addresses the tasks involved in the cultural resource compliance for the Project. The survey and report are to be consistent with the DAHP "Washington State Standards for Cultural Resource Survey Reporting" and EO 05-05. Aqua Terra Cultural Resource Consultants (ATCRC) will aid Mr_ Fall with complying with these legal requirements by identifying the presence of historic resources on the property through completion of the following tasks - Task 1: Background Research ATCRC will conduct background research at appropriate repositories, such as the DAHP, university libraries, local history museums and informants, and use sources appropriate to the task, such as public records, private manuscript collections, online General Land Office records, published (secondary) sources, Sanborn fire insurance maps, and other relevant repositories. The objective of the research should be to develop a full understanding of the historical context, land use patterns, and previously identified sites within the Area of Potential Impact (API). The client will provide ATCRC with a detailed written description of the project area, including relevant documentation (maps, plan sheets, photos, etc.). ATCRC will provide the client with justification for revising/amending the API, if warranted (based on field survey and/or background research). Task 2: Tribal Coordination The relevant tribe(s) will be contacted about the project to identify any concerns about heritage resources within the API and to inform them when field investigations will take place_ This communication is a technical inquiry and does not take the place of any formal consultation required_ Responsibility for formal consultation with tribes in matters of the cultural resource review process is a government -to -government function and will be conducted by DAHP if required_ Aqua Terra Cultural Resource Consultants, LLC Page I Assumptions: - ATCRC will be available to meet with the relevant tribe(s) for one in -person project review meeting_ Task 3: Cultural Resources Survey The cultural resources survey will be completed by ATCRC archaeologists using standard, industry -accepted methods appropriate to the project area and landform. Up to 15 shovel -tests or hand auger probes will be excavated where appropriate, in areas judged to have potential for cultural remains or in areas with poor surface visibility. Depositional setting will be evaluated. Any previously recorded resources will be examined and updated as necessary. All survey activities will comply with the DAHP Survey and Inventory Standards (www.dalipma.gov). Newly identified cultural resources will be fully documented (see Task 4). Special care will be taken to determine site boundaries if archaeological resources are present. Any recovered artifacts will be documented and photographed in the field and returned to the survey location_ Assumptions: Cost Estimate allows for recording of one historic property (the existing structure on parcel no_ 0121039058) and one additional historic/archaeological resource site if discovered. Site boundaries will be determined within parcels approved for access/survey. Cost estimate does not allow for recording of site boundaries that lie outside the approved/scope survey area. A separate cost estimate will be prepared for the client in the case that a Site Protection Plan or additional work (e.g. construction monitoring, recording of site boundaries outside parcel no_ 0121039058, etc.) is required due to discovery of cultural resource material. Task 4: Resource Forms Results of the survey will be summarized. Any previously recorded cultural resources will be examined and updated as necessary_ Newly identified cultural resources within the project area will be fully documented on a Washington State Archaeological Site Form and will include a written description of the site and its setting, sketch maps, USGS quadrant maps, and photographs_ Any structures older than 50 years will be recorded on historic property inventory forms. Task 5: Draft Report ATCRC will prepare a draft summary report of their findings that includes relevant supporting evidence for findings and adheres to the DAHP's Survey and Inventory Standards. The report will provide context on pertinent land use customs and beliefs, identify sites within the project area, discuss methods used to survey the project area, and include recommendations on the eligibility of the site(s) and the likelihood of construction impacts. A draft report will be provided to the client for review six weeks after receipt of notice -to -proceed. Aqua Terra Cultural Resource Consultants, LLC Page 2 Task 6: Final Report Upon receipt of comment from the client, ATCRC will revise and finalize the report to address specific concerns or suggested modifications. The final summary report will be suitable for submission to DAHP, the tribe(s), appropriate agencies and other concerned parties. Due to confidentiality requirements for archaeological site locations, distribution of the report will be restricted beyond any of the aforementioned parties. The report will then be submitted in final form to the client, to DAHP and the tribe(s); upon the clients request ATCRC will facilitate the submission of the final report to other agencies/concerned parties, if applicable. Assumptions: If the client wishes for ATCRC to facilitate the submission of the final report to the aforementioned parties, the client will provide ATCRC with the appropriate agency and concerned party contact information_ Task 7: Project Management ATCRC will coordinate with the client to receive project materials, prepare invoicing and transmit correspondence_ ATCRC will maintain project files to include necessary supporting materials as required. The Project Manager (Sarah Shufelt) will monitor project task performance, schedule, budget, and approve project expenses_ The Project Manager will ensure that systems are in place to conduct quality assurance and quality control on deliverables and correspondence. Assumptions: - The ATCRC Project Manager will be available for regular phone calls with the client and one in -person meeting to facilitate completion of the assignment_ Project Materials The client will supply or facilitate ATCRC acquisition of the following needed for this project- • A general location map; • Preliminary and revised plan maps showing the location and extent of the project; • Any additional descriptive information and design drawings that show the extent/depth of trenching, grading, or other ground disturbance associated with the project; and • The results of any geotechnical boring or subsurface testing that may assist in development of a land use/land formation history_ • Contact information or documented permission from property owners to access the survey area; • Contact information for any agencies or concerned parties that the client would like the report disseminated to, if applicable. Deliverables ATCRC will provide the client with a PDF version of the final report via email and/or by CD via mailing. ATCRC will provide a PDF copy of the report on CD to DAHP, the tribe(s), and Aqua Terra Cultural Resource Consultants, LLC Page 3 appropriate agencies and concerned parties if requested by the client. Final report deliverable will be sent to client within eight weeks of notice -to -proceed.

S.E. Port Orchard, WA 98367 January 9, 2012 Re: Septic system abandonment at 3124 SW 302°d Place in Federal Way, Washington. Dear Mr. Fall, This letter is specific in outlining code requirements governing septic system abandonment. More specifically there are two codified sources appropriate for guiding abandonment found at the state and county levels. The state code, WAC 246-272A is a general minimum, where King County Title 13 has more specific guidance. Below are the two appropriate code citations: WAC 246-272A-0300-Abandonment Persons permanently abandoning a septic tank, seepage pit, cesspool, or other sewage container shall: (1) Have the septage removed by an approved pumper; (2) Remove or destroy the lid; and (3) Fill the void with soil or gravel. King County Title 13.04.054 Abandonment. A. Persons permanently removing a septic tank, seepage pit, cesspool or other OSS wastewater tanks from service shall within thirty days: 1. Have the septage removed by an approved pumper; and 2. Remove or destroy the lid; and 3. Fill the void with compacted soil or gravel; and 4. Report the abandonment to the health officer on a form obtained from the health officer and accompanied by the fee specified in the fee schedule. RESUBMITTED FEB 14 2012 CITY OF FEDERAL WAY CDs B. Contaminated rock, sand and gravel material from repairs to failing OSS shall be properly disposed of by either burying at an appropriate location approved by the health officer or transported to an approved sanitary landfill. The process of disposal shall be supervised by a licensed master installer. (R&R No. 08-03 § 3, 2008: R&R No. 99-01 § 2 (part), 3-19-99). King County Title 13.04.054 outlines in greater detail the process and documentation of septic system abandonment. Applying these sections of codes to the referenced project, the following would be an appropriate procedure for complete abandonment: 1) The wastewater tank shall have all septage removed by an approved pumper. 2) The wastewater tank shall have the lid destroyed. 3) Fill all voids with pea gravel. Pea gravel will more adequately fill voids and need far less compaction. Vibration due to compaction may cause some adverse site conditions on an already sensitive site. 4) Report the abandonment on the appropriate Report of Wastewater Tank Abandonment with appropriate fee. (See attached form) Any existing drainf eld requires no disposal or special treatment if the following conditions are present: 1) System is not failing. 2) Rock, sand and gravel material remain underground. 3) Rock, sand and gravel material unearthed have no wastewater commingled with the earth material. It appears that a small portion of the existing drainfield could be unearthed during the proposed expansion project. If there are contaminated soils then disposal should be in accordance with Title 13.04.054 B. The above guidance is limited to the referenced site description and is based upon information provided by owners or owners agent. If you have any question please contact me at (253) 862-4307.

The east portion of the lot is forested and undeveloped except for an existing gravel driveway. The west portion of the lot has been developed as a single family residence with an attached garage (the residence was built in 1952). Access to the site is from 33rd Avenue SW. To the southeast of the residence the site is relatively flat. To the northwest of the residence the site features a steep slope (>40%) to the northwest to the beach of Puget Sound. There is a bulkhead sea wall along the shoreline and a 5' to 10' wide flat area between the bulkhead wall and the toe of the steep slope. No offsite improvement is proposed. The proposed onsite improvement includes 771 sf new house addition and 616 sf of new deck at the northwest side of the existing residence, 558 sf new court space at the front entrance, 616 sf new detached garage, 1941 sf new asphalt pavement in front of the existing and new garages, 82 sf of new front and side additions. Total new impervious area is 4584 sf. Total new pollution generating impervious area is 1941 sf which is less than 5000 sf and water quality treatment is not required. Total existing impervious area to remain is 2614 sf which includes a 1298 sf house, a 356sf garage and 960 sf of existing gravel driveway. Total impervious area is 7198 sf. Since this project will result in no more than 10,000 square feet of total impervious surface added on or after January 8, 2001, no more than 5,000 square feet of new impervious surface, and no more than 35,000 square feet of new pervious surface, it meets the requirements for Small Project Drainage Review.

All proposed impervious surface (4,584 sf total) will be mitigated with flow control BMPs. There will be minimal new pervious surface. The total cleared area is less than 35,OOOsf, which is the maximum new pervious surface allowed without flow control BMPs. We are under this number; therefore, no BMPs are required for this surface. There is a steep slope area downstream of the proposed building addition. Therefore, there is no way to achieve the minimum required 100 feet of native vegetated flowpath segment with a slope of 15% or less. Therefore, full dispersion is not feasible. Also full infiltration is not feasible due to the steep slope area downstream of the building. Since the north portion of the site is in the shore line of Puget Sound, the Direct Discharge Exemption applies, Flow control is not required. Runoff from the proposed development will be tight lined to a location near the beach of Puget Sound for direct discharge and for steep slope protection. Total collected impervious area is 7,187 square feet which is less than 10,000 square feet. 6" tight lines will be used (SWDM C.1.2.3). Energy dissipation is required for the outfall. Two type 1 catch basins (used as stilling wells) and a 10 feet long by 4 feet wide gravel dispersal trench with 10 linear feet of 6" perforated PVC pipe will be installed 2 feet behind the bulkhead sea wall (parallel with the wall) to provide the energy dissipation. Water will leach out from the perforated PVC pipe to the gravel dispersal trench and then flows to the weep holes (Y to 4" clay pipes at 8' o.c. protruded through the bulkhead). If the weep holes reach their capacity, water will bubble up to the top of the dispersal trench and sheet flow over the top of the bulkhead to the Puget Sound. Stilling well design: Step 1: Select approach pipe diameter, D, and discharge, Q Q100yr = C*I*A = C*Pr*Ar*Tc**(-Br)*A = 0.9*4.35*2.61 *6.3**(-0.63)*0. 165 = 0.53 cfs. Where C = 0.9 for impervious area A = 7198 sf. = 0. 165 ac. Tc = 6.3 minute for small site area Pr = 4.35 inches for 100 year 24 hour storm event Ar = 2.61 and Br = -0.63 Approach pipe diameter D = 6" = 0.5' Step 2: Obtain well diameter, Dw from Figure 12.2 Dw = D = 0.5' Use Type 1 CB with 26"x22" opening area, o.k. Step 3: Calculate the culvert slope. The depth of the well below culvert invert, H1 from Figure 12.3 S = 55.17%, V/H = 0.5517 H1 = 0.45 * Dw = 0.23' Use Type 1 CB, H1 = 2', o.k. Step 4: The depth of the well above the culvert invert, H2 = 2*D = 2 * 0.5' = 1' minimum, use 3.5'. Step 5: The total height of the well, Hw = H1 + H2 = 3.5'+2' = 5.5'. 3.2.1 RATIONAL METHOD FIGURE 3.2.1.D 100-YEAR 24-HOUR ISOPLUVIALS �`e-' o coUNiv ,Hea c, }.` ryr.. �''''• {-- a -•,`r_ N C051 HTY 4 -Z w ; _ �'� — ��+ � � "`[. � •"S:. r- s : �T {'�� � I• F ur -� I I i� S l:� Sr CP 4,4 SIT A - s• l Imo_. r � F-S'�`'i"c� � 'i fj �= ciurna •� _.yy`am� -.t :� '� ! - � � . +' i 1`� :^i _ /J I - _ �yyGyS� y`:' , � �~ !1 , ,! ; ,e4uReefR • _ LL .C� _r •[ .eS —2� .`area 1 f ce v • + 1 RRr 1 i V FAIL C6 COUIITY J WESTERN a• �• ,-` 6.5 KING COUNTY �o . p4 -:�� .n_ 6.0 0 100-Year 24-Hour Precipitation in Inches 0 2 4Miles h. 4P 2009 Surface Water Design Manual 3-17 1/9/2009 Hydraulic Design of Energy Dissipators for Culverts and Channels Hydraulic Engineering Circular Number 14, Third Edition Chapter 12: Stilling Wells The design of the US Army Corps of Engineers' stilling well energy dissipator is based on model tests conducted by the US Army Corps of Engineers (USACE, 1963; Grace and Pickering, 1971). It is illustrated in Figure 12.1. The stilling well can be used in channels with moderate to high concentrations of sand or silt and where debris is not a serious problem. The stilling well should not be used in areas where large floating or rolling debris is expected unless suitable debris -control structures are used. The highway uses of stilling wells are at the outfalls of storm drains, median, and pipe down drains where little debris is expected. The design of the stilling well is Initiated atter the size ano aischarge or the incoming pipe are aeierminuu. riquie 12.2 is used to select the stilling well diameter, Dw. The model tests indicated that satisfactory performance can be maintained for K,Q/D- ratios as large as 10, with stilling well diameters from 1 to 5 times that of the incoming conduits. (K� is a unit conversion constant equal to 1.811 in SI and 1.0 in CU.) These ratios were used to define the curves shown in Figure 12.2. The optimum depth of stilling well below the invert of the incoming pipe is determined by entering Figure 12.3 with the slope of the incoming pipe and using the stilling well diameter, Dw, previously obtained from Figure 12.2. The height of the stilling well above the invert is fixed at twice the diameter of the incoming pipe, 2D. This dimension results in satisfactory operation and is practical from a cost standpoint; however, if increased, greater efficiency will result. Tailwater also increases the efficiency of the stilling well. Whenever possible, it should be located in a sump or depressed area. Riprap or other types of channel protection should be provided around the stilling well outlet and for a distance of at least 3Dw downstream. The outlet may also be covered with a screen or grate for safety. However, the screen or grate should have a clear opening area of at least 75 percent of the total stilling well area and be capable of passing small floating debris such as cans and bottles.
