To access the development an existing 30' easement off 120th Ave SE will be improved to urban minor access road standard consisting of a sidewalk on the north side and curb & gutter on both sides. Additional improvements include a recreation area located near the southeast comer of the site, storm drainage detention and water quality facilities to treat and detain the proposed storm water, and grading. An asphalt pedestrian path will be constructed along the east side 120th Ave SE, east of the existing roadside ditch, from the new access road to SE 188th Street. Impervious surfaces will include the future residential roofs, paths and driveways, and the proposed access road improvements and 120th Ave SE pedestrian improvements. Utilities including sanitary sewer and water will also be constructed to support the proposed residential development. The existing parcel is zoned R6. The project site is located in the SW Quarter of Section 33, Township 23 N, Range 5 E, WM, King County, Washington and is shown on the vicinity map below. -~ I (Boulev~d I e P.ark: I I < \ r---" I J J '-s'"e-,-1sa=,h~s~, ---,-:=~-------'~:===:.•sffiim,.:J.;::::) !;i ... 1f\ ! 6 ffl ]!;::::.:.::::::~, ~ PROJECT SITE \ I I Jhln ~ ~LJ ,;;, m ~ ~ '---===,--------~ ~ SE 92 d S ~1:::::;::::':::::::::::::= SE192:S1 wnnd]l ~ 1 " 1 -_JI l~J !r~ 1@ HITDNE SHORT PLAT• TIR 5/30/2009 FIGURE 2 -VICINITY MAP ~---1 !

Discharge at the natural location: Currently, the site drains from the west to the east to the unregulated wetland along the easterly boundary of the site. The proposed onsite storm water discharges to a flow dispersion trench which sheet flows to the natural location. The pedestrian path along 120th Ave SE sheet flows to its natural location, the adjacent roadside ditch. 2. Off-site Analysis: A Level 1 off-site analysis was completed for this project and is included in this submittal. 3. Flow control: The proposed detention/wet vault is sized to meet Conservation Flow Control requirements per the 2005 KCSWDM using the KCRTS program. This requires level 2 flow control with pre-developed conditions for the site modeled as till forest, the historic land cover. Bypassed flows are included in the design of the proposed detention vault. 4. Conveyance system: Flows will be conveyed using catch basins and tight line culverts. 5. Erosion and sedimentation control: TESC measures are shown on the engineering plans submitted with this TIR. 6. Maintenance and Operations: Maintenance and Operations procedures are included in Section 10 of this TIR. 7. Financial guarantees and liability: The applicant or the Contractor will provide bonds for performance and maintenance based upon the information included on the Bond Quantity Worksheet provided in Section 9 of this TIR. 8. Water Quality: The new impervious surface area subject to vehicular traffic is greater than 5,000 square feet for this project. As a result, water quality treatment is required. Water quality is to be provided with a detention/wet vault and sized according to Basic Water Quality Treatment requirements per the 2005 KCSWDM. Special Requirements 1. Other adopted area-specific requirements: Conservation Flow Control has been provided. 2. Floodplain/Floodway delineation: Not applicable. 3. Flood protection facilities: Not applicable. 4. Source controls: Not applicable. 5. 011 Control: Not applicable. Section 3 -Off-site Analysis This Level 1 Downstream Analysis is submitted as required by Core Requirement #2, Section 1.2.2, of the 2005 KCSWDM. Core Requirement #2 requires a qualitative analysis of upstream and downstream drainage conditions with an initial project submittal. Task 1: Study Area Definition and Maps: See Section-1 of this report for a detailed Study Area Definition. The project site as mappE;d by KCSWDM appears to be in the Soos Creek Drainage Basin.

Upstream Drainage Area : The landscaped area directly west of the site sheet flows to the west onto the project site . Downstream Drainage Area : Stormwater leaving the site sheet flows to the west through forested slopes from 0-20%. See Task 4 of this report for further information . Task 4: Drainage System Description and Problem Descriptions: The following aerial photo displays the site , contributing upstream drainage area, and downstream drainage pathway up to Y. mile from the site .

Task 5 -Mitigation of Existing or Potential Problems : A combination detention and water quality vault has been designed to mitigate potential downstream problems . Section 4-Flow Control and Water Quality Facility Analysis and Design Flow control Analysis and Design The drainage on the existing site was analyzed for this project with KCRTS software . Figures provided in the 2005 KCSWDM and KCRTS manual were used to determine project location and parameters. A portion of the site and required frontage improvements located near the northeast corner of the subject site are not able to be collected and treated in the proposed detention and water quality facility. As mitigation for the uncollectable area , this project will collect an equal area from offsite paved surfaces within 116th Avenue SE and provide flow control and water quality treatment. A positive aspect of this proposal is that the uncollectable are from project site and required sidewalk improvements are low impact (non vehicular traffic) P.G.I .S. The proposed offsite trade area to be collected and treated is entirely P.G.I.S .

This does not match the order shown in the dev peaks analysis. However, each dev peak inflow event is listed here. The new calculated 25 year peak flow (hyd 2) is less than or equal to the original pre-developed 25 year peak flow (0.08). The new 2 year peak flow (hyd 6) is less than or equal to the original 2 year peak flow (0.036). Therefore the conservation flow control standard is achieved. • The following hydrographs display the developed storm event entering the vault and the corresponding vault outflow. Cumulative storm events over a short period of time have an additive effect on the vault outflow.

A Geotechnical Engineering Study was performed by Soil & Environmental Engineers, Inc. and has been submitted with this TIR under separate cover. Section 7 -Other Permits Upon approval of the engineering plans by KCDDES, a ROW use permit is required for all work within KC ROW. In addition, construction of water and sanitary sewer facilities to serve this project must conform to and be approved by the Soos Creek Water and Sewer District. Separate building permit applications for residential construction on individual lots must be submitted and approved by King County DOES. Section 8 -CSWPPP/TESC Analysis and Design A Construction Storm Water Pollution Prevention Plan is located in Appendix B . Temporary Erosion and Sediment Control Per Appendix D of the 2005 King County Surface Water Design Manual, the following information is presented in consideration of compliance with King County Erosion and Sediment Control Standards: Clearlng Limits have been defined on the TESC/CSWPPP. Cover Measures both temporary and permanent are addressed in the construction sequence. Perimeter Protection is proposed in the form of Silt fence. Traffic Area Stablllzatlon is proposed in the form of a Temporary Construction Entrance. Sediment Retention is proposed in the form of silt fence and sediment trap at the project perimeter until the vault is constructed. The vault will then be used for temporary sediment retention. Surface Water Collection is proposed by utilizing the vault for temporary surface water collection. DeWaterlng Control is not anticipated to be required for this project. If required, a 'Baker" filtration tank will likely be utilized to filter stormwater prior to release into existing downstream storm drainage system. Temporary Dust Control other than the temporary construction entrance is not anticipated to be required. If fugitive dust becomes an issue, watering the soil before it is worked will alleviate the problem. Temporary Flow Control during construction is proposed in the form of utilizing the proposed detention vault once it has been constructed. See Construction Sequence .

Please show the dimensions and area calculation for the combined drainage and recreation tract. Please note that at a minimum, 2,340 square feet shall be allocated for recreation. The grass-paved driveway to access the drainage vault cannot be included within the required area. The area allocated for recreation could include landscaping buffers. No dimension of the recreation tract can be less than 30 feet. 2. At a minimum a 400-square-foot tot lot area must be provided. The proposed 215-foot toddler area (sand box) is inadequate and does not meet the code. In addition to the tot lot area, one additional recreation facility must be provided per KCC 21A.14.180.E2. A pull bar as the only recreation structure does not meet the code requirement. A basketball court or a picnic area with tables and a large grassy area for throwing a baseball or Frisbee may be acceptable for a recreation facility. 3. Please show fencing around the entire perimeter of the tract except the street side. The fencing along the boundary of the tract and Lot 6 may be 4-feet high and see-through. 4. Landscaping notes must include the type and method of irrigation. 5. The proposed improvements must not conflict with the engineering requirements for the drainage facility or its maintenance. Normal maintenance includes I -• .. driving heavy equipment up to the access point, opening vault access points and lowering equipment into the vault to remove sediments. Please show the vault access points for maintenance and any other drainage related structures that will be part of the recreation tract. Please submit the following by December 22, 2008: I. 2. 3. 4. 5 copies of a revised final recreation plan, addressing the-items referred-above 5 copies of a revised Bound Quantity Worksheet for the landscaping and other improvements 5 copies of play equipment and recreation tract furnishings specifications A copy of this memo If you have any questions regarding this letter, please contact me at (206) 296-7173.

The following outlines some of our correspondence with the County including timeline, used as the basis of our design. This is an attempt to respond to your statements included in the Hitone Short Plat letter dated April 27, 2007. Items 7, 8 and 9: Plan Revision for change in stonn drainage, stonn drainage easements on lots, and downstream drainage: The original Short Plat showed a detention tank and underground treatment facility. In late November of 2007, we found the downstream conveyance system would not be completed at the time of our engineering review. So, for the Owner to proceed with his project an above ground system was designed per King County's 1998 standards. We contacted the County to see if we could place the detention .and water quality in a SD easement over a residentiallot. It is our understanding from the 1998 King County Manual the detention pond must be in a dedicated Tract ifit is to be maintained by the County. Thus, if this is a privately maintained facility it would not have to be in a Tract. We spoke with Kate Roads (206-296-8046) on 12-12-06 and discussed several options for storm drainage system. She stated the County prefers all SD to be in one tract but SD easements on lots are allowable. She also stated the system we design must function as a complete system now. The owner, at a future date when the downstream conveyance system is available, will potentially put the detention and WQ below ground, thus reclaiming the lot area the SD easement currently occupies. So, the system we designed is a stand alone system. Short Plat Condition 4, part D, states we would have to submit a revision to the application with a new conceptual drainage plan. We contacted the County again to see how to proceed. We did not know if the revision was a formal Revision or exactly what we were required to do. We first contacted Freeshteh Dehkordi in late November she referred us to Curt Foster. Curt was unsure and was going to check with someone else in his office. He said a formal Revision is normally needed when the number oflots change. ~ e still had 6 lots with Lot 5 partially impacted and Lot 6 completely impacted by the storm drainage.) He called back and referred us on to Kim Clauson (206-296-7167). We spoke with Kim Clauson on 12-06-06. She said to submit extra copies of our plans to engineering and they would let us know if additional information was necessary. She did not think a formal Revision would be required. Item 10: No road access to SD oudet: This will be included when the plans are re-submitted. Item 11: Cul-de-sac design does not meet K,e'Stiihdards: We coordinated with Chris Langly (206-296-7155 or 206b63-61'0?2Joh several occasions (10-30-06, 10-31-06 and 12-12-06) to determine the road and cul-deJsac desigh el[r;'.,ents. I\·te island the only design standard we are not meeting? An island is not required for this r~ad classification. We pat it in as a WQ element.

To implement the engineering review process, our office will use a new procedure for managing the permit application to provide applicants with an enhanced level of customer service. A project manager will be assigned to your project to provide a fee estimate for the anticipated scope of review and will also monitor and manage the permit application throughout the review process. Your application for engineering review was received by our office on March 30, 2007 and will be processed using the Project Manager Program. The enclosed information provides a summary of the fee estimate for the anticipated work disciplines and also discusses the submittal process and disclaimers which may affect the final permit fees. The fee estimate includes the scope of work for engineering plan review only and does not evaluate other final plat requirements such as construction inspection and review of plat recording documents. During our initial screening process of the engineering plans, it was determined that the short plat has been significantly changed since preliminary approval and the designs are not acceptable for engineering review. The original short plat proposed a detention vault located beneath the roa_dway and recreation tract; however, the current design shows a storm pond and bioswales located within the lot areas which does not meet County design requirements. In addition, several other design requirements for roads and drainage do not meet County standards. The design items identified during the screening process which do not comply with County standards are listed as disclaimers on the attached fee estimate form. Due to the missing information, the fee summary is a rough estimate and is subject to modification based upon the disclaimers noted in the fee estimate form. Heidi Kuehnienz April 27, 2007 Page 2 Before continued review of the engineering submittal, the site plans must be revised to correspond with the original design concept for the preliminary short plat or an application for short plat revision must be submitted to the planning section in our office. The short plat revision is also noted as a requirement in short plat condition 4 regarding the off site drainage pipe which is not addressed on the current design plans. Please contact the project planner Fereshteh Dehkordi at 206-296-7173 to discuss the requirements for a short plat revision. The short plat revision must be processed before any further review of the engineering designs. In addition to engineering design documents, our Department must also review and approve the recreation space plan as required by short plat condition 13. Please be aware that the recreation plan must be submitted to our planning section as a separate permit application with fee payment. The requirements for submitting recreation plans may also be discussed with Fereshteh Dehkordi at 206-296-7173. Our current records for the short plat do not list your name as the original applicant. If the property has changed ownership, the enclosed Transfer of Applicant Status Form (CASF) must be provided in your next submittal. Once the attached fee estimate form is signed and submitted to our Department along with the estimated fee payment, applicant status form, and revised engineering plans, your project will be assigned for further review. All fee payments shall be made to the cashier in the DOES permit center using activity number L07SRO 19 and other forms or plan documents shall be submitted to my attention in the Land Use Services Division. If you have any questions regarding the permit fees or other aspects of the engineering review process, please contact the project manager, Pete Dye via email pete.dye@metrokc.gov or by telephone at 206-296-7185. sfJ;J Peter D)'t:.E.

The STC has discussed the proposed development with the applicant to clarify technical details of the application and to determine the compatibility of this project with applicable King County plans, codes, and other official documents regulating this development. As a result of preliminary discussions, the applicant presented the Technical Com.mittee with a revised site plan on January 9, 2006. The revision to address some of the technical issues was minor. No change to the road or lot layout was made. Report and Decision -I -L04S0065 D. NATURAL ENVIRONMENT 1. Topography: The site slopes down gently from west to east. The maximum slope is 3%. 2. Soils: One soil type is found on this site per King County Soil Survey, 1973. The entire site is classified AgB. The following are characteristics of AgB soils: AgB -Alderwood gravely, sandy loam; 0-6% slopes. Runoff is slow and the erosion hazard is slight. This soil type has moderate limitations for low building foundations due to a seasonally high water table, and severe limitations for septic tank filter fields due to very slow permeability in the substratum. 3. Wetlands: A wetland and report was prepared by Altmann Oliver Associates dated December 22, 2004. The report identified a small (175 sq.ft.) isolated shallow wetland partly on site. This wetland is exempt from regulation. The site lies within the Soos Creek drainage basin. 4. Vegetation: This site is primarily covered in grasses. Scattered evergreen and deciduous trees and sherubs occur in limited numbers. 5. Wildlife: Small birds and animals may inhabit this site; however, their population and species are limited due to nearby development. No threatened or endangered species are known to exist on or near the property. 6. The Sensitive Areas Folio does not identify any mapped sensitive areas as being present on this site. · E. NEIGHBORHOOD CHARACTERISTICS: The property lies within a gradually urbanizing area east of the City of Renton. The proposed subdivision of Fleuve Des Voies, KC File L04P0002, with 38 residential lots is on parcels east of the site and is currently under review by ODES. There are larger lots with potential for re-subdivision to the west and north of the site. The properties south of the site are developed with single family residences. The site and the surrounding parcels are zoned Residential (R-6) with six dwelling units per acre. The proposed subdivision site is undeveloped. F. DESIGN FEATURES 1. Lot Pattern and Density: The proposed density and lot layout meets the density requirements of R-6 and the Short Subdivision Code. 2. Access/Roadway Section: The site obtains access to 1201 h Avenue SE via a 30- foot wide easement extending east from the road to the site. The easement will be improved to an urban minor access road standards consisting of curb, gutter and sidewalks on the north side of the road. 3. Drainage: Currently drainage from the property leaves the site in the form of sheet flow. After development. storm water runoff (from the proposed under ground vault) will be conveyed eastward (same direction) to a proposed development on the neighboring property. The applicant has received a letter of agreement from the property owner directly east of the site to allow a drainage easement across his property for this purpose. The on-site vault will be located in the southeast corner of the property. It will be designed for Level II flow control and basic water quality (1998 Surface Water Design Manual). 3. Other Design Features: The proposal includes a 3.173-square-foot recreation tract located southeast of the site. This tract will be improved with landscaping and a toy structure for the benefit of the subdivision's future residents. Report and Decision . 2. L04S0065 G. PUBLIC SERVICES 1. Sewage Disposal: The applicant proposes to serve the subject subdivision by means of a public sewer system managed by the Soos Creek Water and Sewer District A Certificate of Sewer Availability, dated December 2004 indicates this sewer district's capability to serve the proposed development 2. Water Supply: The applicant proposes to serve the subject subdivision with a public water supply and distribution system managed by the Soos Creek Water and sewer District. A Certificate of Water Availability dated December 17, 2004 indicates this water district's capability to serve the proposed development. 3. School facilities: The subject subdivision will be served by Benson Elementary, Nelson Middle, and Lindberg Senior High Schools, all located within the Renton School District. 4. School Access: The District has indicated that the future students from this subdivision will walk to Benson Elementary and the middle and high school students will be bussed from the intersections of 1201h Avenue SE and SE 1881 h Street and from the intersection of SE 188 1h and 1161h Avenue SE respectively. Currentlt, there are no sidewalks along 1201 h Avenue SE to its intersection with SE 1881 Street. Sidewalk improvements are expected along SE 1881 h Street by other subdivision proposals in the area. This improvement together with the required off-site pedestrian improvements (See SEPA condition below) will complete a continuous walkway facility from the site to the school bus pick up areas. 5. Parks and Recreation Space: The nearest public park is Soos Creek Park located along SE 192"d Street a few miles southeast of the site. KCC 21 A 14 requires subdivisions in the UR and R zone clas$ifications to either provide on- site recreation space or pay a fee to the Parks Division for establishment and maintenance of neighborhood parks. At this time, the applicant is proposing to provide a 3,100 square-foot recreation tract on the site. The site of the recreation tract is encumbered by the Soos Creek utility easement The Soos Creek Water and Sewer District has agreed to reduce the easement width to 10-foot wide for the water main. The District has no objection to development of a recreation tract on the easement provided no toy structure is anchored within the easement, see attachment~. KCC 21A.14.190 requires subdivisions to provide tot/children play areas within the recreation space on-site. The proposal must include a 270-square-foot play area with the required recreation tract. The recreation tract plan must be reviewed and approved by the Soos Creek Utility District. G. SEPA THRESHOLD DETERMINATION: Pursuant to the State Environmental Policy Act (SEPA), RCW 43.21 C, the responsible official of the LUSD issued a mitigated threshold determination of non-significance (MONS) for the proposed development on March 24, 2006. This determination was based on the review of the environmental checklist and supporting documentation filed with the applicati,on, resulting in the conclusion that the proposal would not cause probable significant adverse impacts on the environment provided the following measures are attached to the project as conditions: In accordance with the requirements with RCW 58.17.110 (2), the Applicant shall improve 120th Avenue SE, from the plat entrance in the 19000 block northward to the intersection of SE 188th Street/120th Avenue SE by providing a paved walkway along the easterly side of 120th Avenue SE.

HISTORY and BACKGROUND The Subdivision Technical Committee (STC) of King County has conducted an on-site examination of the subject property. The STC has discussed the proposed development with the applicant to clarify technical details of the application and to determine the compatibility of this project with applicable King County plans, codes, and other official documents regulating this development. As a result of preliminary discussions, the applicant presented the Technical Committee with a revised site plan on January 9, 2006. The revision to address some of the technical issues was minor. No change to the road or lot layout was made. Report & Decision Page I of9 L04S0065 • D. E. F. NATURAL ENVIRONMENT 1. Topography: The site slopes down gently from west to east. The maximum slope is3%. 2. Soils: One soil type is found on this site per King County Soil Survey, 1973. The entire site is classified AgB. The following are characteristics of AgB soils: AgB -Alderwood gravely, sandy loam; 0-6% slopes. Runoff is slow and the erosion hazard is slight. This soil type has moderate limitations for low building foundations due to a seasonally high water table, and severe limitations for septic tank filter fields due to very slow permeability in the substratum. 3. Wetlands: A wetland and report was prepared by Altmann Oliver Associates dated December 22, 2004. The report identified a small (175 sq.ft.) isolated shallow wetland partly on site. This wetland is exempt from regulation. The site lies within the Soos Creek drainage basin. 4. Vegetation: This site is primarily covered in grasses. Scattered evergreen and deciduous trees and sherubs occur in limited numbers. 5. Wildlife: Small birds and animals may inhabit this site; however, their population and species are limited due to nearby development. No threatened or endangered species are known to exist on or near the property. 6. The Sensitive Areas Folio does not identify any mapped sensitive areas as being present on this site. NEIGHBORHOOD CHARACTERISTICS: The property lies within a gradually urbanizing area east of the City of Renton. The proposed subdivision of Fleuve Des Voies, KC File L04P0002, with 38 residential lots is on parcels east of the site and is currently under review by ODES. There are larger lots with potential for re-subdivision to the west and north of the site. The properties south of the site are developed with single family residences. The site and the surrounding parcels are zoned Residential (R-6) with six dwelling units per acre. The proposed subdivision site is undeveloped. DESIGN FEATURES 1. Lot Pattern and Density: The proposed density and lot layout meets the density requirements of R-6 and the Short Subdivision Code. 2. Access/Roadway Section: The site obtains access to 1201 h Avenue SE via a 30- foot wide easement extending east from the road to the site. The easement will be improved to an urban minor access road standards consisting of curb, gutter and sidewalks on the north side of the road. 3. Drainage: Currently drainage from the property leaves the site in the form of sheet flow. After development, storm water runoff (from the proposed under ground vault) will be conveyed eastward (same direction) to a proposed development on the neighboring property. The on-site vault will be located in the southeast corner of the property. It will be designed for Level II flow control and basic water quality (1998 Surface Water Design Manual). 3. Other Design Features: The proposal includes a 3,173 square foot recreation tract located southeast of the site. This tract will be improved with landscaping and a toy structure for the benefit of the subdivision's future residents. Report and Decision L04S0065 .4 G. PUBLIC SERVICES 1. Sewage Disposal: The applicant proposes to serve the subject subdivision by means of a public sewer system managed by the Soos Creek Water and Sewer District. A Certificate of Sewer Availability, dated December 2004 indicates this sewer district's capability to serve the proposed development. 2. Water Supply: The applicant proposes to serve the subject subdivision with a public water supply and distribution system managed by the Soos Creek Water and sewer District. A Certificate of Water Availability dated December 17, 2004 indicates this water district's capability to serve the proposed development. 3. School facilities: The subject subdivision will be served by Benson Elementary, Nelson Middle, and Lindberg Senior High Schools, all located within the Renton School District. 4. School Access: The District has indicated that the future students from this subdivision will walk to Benson Elementary and the middle and high school students will be bussed at the intersections of 1201 h Avenue SE and SE 188th Street and at the intersection of SE 1881h and 1161 h Avenue SE respectively. Current/X, there are no sidewalks along 1201h Avenue SE to its intersection with SE 188 Street. Sidewalk improvements are expected along SE 188th Street by other subdivision proposals in the area. 5. Parks and Recreation Space: The nearest public park is Soos Creek Park located along SE 192"d Street a few miles southeast of the site. KCC 21A.14 requires subdivisions in the UR and R zone classifications to either provide on- site recreation space or pay a fee to the Parks Division for establishment and maintenance of neighborhood parks. At this time, the applicant is proposing to provide a 3,100 square-foot recreation tract on the site. The site of the recreation tract is encumbered by the Soos Creek utility easement. The Soos Creek Water and Sewer District has agreed to reduce the easement to 10-foot wide for water main. The District has no objection to development of a recreation tract on the easement provided no toy structure is anchored within the easement, see attachment i. KCC 21A.14.190 requires subdivisions to provide tot/children play areas within the recreation space on-site. The proposal must include a 270-square-foot play area with the required recreation tract. The recreation tract plan must be reviewed and approved by the Soos Creek Utility District. G. SEPA THRESHOLD DETERMINATION: Pursuant to the State Environmental Policy Act (SEPA), RCW 43.21 C, the responsible official of the LUSD issued a mitigated threshold determination of non-significance (MONS) for the proposed development on March 24, 2006. This determination was based on the review of the environmental checklist and supporting documentation filed with the application, resulting in the conclusion that the proposal would not cause probable significant adverse impacts on the environment provided the following measures are attached to the project as conditions: In accordance with the requirements with RCW 58.17 .110 (2), the Applicant shall improve 120th Avenue SE, from the plat entrance in the 19000 block northward to the intersection of SE 188th Street/120th Avenue SE by providing a paved walkway along the easterly side of 120th Avenue SE. The walkway, per Section 3.09 of the KCRS shall be selected and designed by the Applicant's engineer in accordance with any one of the following standards, and upon approval by ODES, constructed. A. A full width (8 feet) paved shoulder B. A paved shoulder of no less than four (4) feet in width, separated by vehicle traffic by either an extruded curb or an unpaved gravel shoulder strip Report and Decision L04S0065 H. C. A concrete curb and gutter, and sidewalk section FINDINGS/CONCLUSIONS: The subject subdivision will comply with the goals and objectives of the King County Comprehensive Plan and will comply with the requirements of the Subdivision and Zoning Codes and other official land use controls of King County (e.g. 1993 King County Road Standards, 1998 Surface Water Design Manual, etc.), based upon the conditions for final short plat approval.

SHORT SUBDIVISION File No. L04S0065 DESIGN FEATURES 2. Access/Roadway Section: The proposal obtains access off 20th Avenue SE by means of a private easement. The road serving this short plat will be improved to the urban minor access street standard. It will terminate at a cul-de-sac bulb located near the center of the property. 3. Drainage: Currently drainage from the property leaves the site in the form of sheet flow. After development storm water runoff (from the proposed under ground vault) will be conveyed easterly (same direction) to a proposed development on the neighboring property. The on-site vault will be located in the southeast property corner. It will be designed for Level II flow control and basic water quality (1998 Surface Water Design Manual). DECISION: 2. Access Requirements 1993 King County Road Standards (KCRS) (KCC 14) Final short plat approval shall require full compliance with the provisions set forth in the King County Road Standards (KCRS), including engineering plans for all road and site improvements. The engineering plans shall be prepared by a professional civil engineer licensed in the state of Washington. DOES strongly recommends that the engineering plans be submitted at least two years prior to the expiration date of the project. All construction and upgrading of public and private roads within this short plat shall comply with the following requirements unless otherwise approved by ODES (KCRS Section1 .03). a. The road serving the property shall be designed as an urban minor access street (Section 2.03). It shall extend from 20th Avenue SE to the cul-de-sac (CDS) bulb located at its eastern terminus (Section 2.07). b. A permanent CDS bulb shall be improved as shown on the revised site plan (KCRS Section 2.08). c. The off-site portion of the road improvements may remain in the existing easement. However, the on-site improvements shall be place in a tract. The tract shall be an undivided ownership to the lots it serves, and the lot owners shall be responsible for its maintenance. d. The proposed road improvements shall address the requirements for road surfacing outlined in KCRS Chapter 4. As noted in section 4.01 F, full width pavement overlay is required where widening existing asphalt. e. Modifications to the above road conditions may be considered by King County pursuant to the variance procedures in KCRS 1.08. m. The following notes shall be shown on the final recorded short subdivision: (1) All private easements and/or tracts to be maintained, repaired, and/or rebuilt by the owners of the parcels having legal access there from and their heirs, assigns or successors, unless and until such roads are improved to King County standards and are dedicated and accepted by King County for maintenance. Report and Decision L04S0057 & L04S0058 ... (2) All restrictions, easements, tracts, and their purpose shall be shown on the final recorded short subdivision. 3. Surface Water Management and Control 1998 King County Surface Water Design Manual (SWDM) (KCC 9) The proposed short plat qualifies for full drainage review as outlined in chapter one of the SWDM, Final short plat approval shall require full compliance with the drainage provisions set forth in King County Code 9.04. A professional civil engineer licensed in the State of Washington shall prepare drainage plans and a technical information report as outlined in Chapter 2 of the drainage manual. The drainage plan submittal shall demonstrate compliance with all applicable Core and Special Requirements. Compliance may result in reducing the number and/or location of lots as shown on the preliminary approved short plat. Preliminary review has identified the following conditions of approval, which represent portions of the drainage requirements. All other applicable requirements in KCC 9.04 and the Surface Water Design Manual (SWDM) must also be satisfied during engineering and final review. a. Engineering plans and analysis shall comply with the SWDM. Prior to short plat recording, the applicant shall submit engineering plans to address the required short plat improvements. King County approval of drainage and roadway plans is required prior to any construction. Permit fees for review and inspection shall be paid as required by County codes and policies. Bonding for the drainage plans will also be established as determined by ODES prior to plan approval. After receiving drainage plan approval, the applicant shall contact the DDES Land Use Inspection Section to schedule a pre-construction meeting prior to performing work on the site. b. Current standard plan notes and ESC notes, as established by ODES Engineering Review shall be shown on the engineering plans. c. The following note shall be shown on the final recorded plat: "All building downspouts, footing drains, and drains· from all impervious surfaces such as patios and driveways shall be connected to the permanent storm drain outlet as shown on the approved construction drawings# on file with ODES and/or the Department of Transportation. This plan shall be submitted with the application of any building permit. All connections of the drains must be constructed and approved prior to the final building inspection approval. For those lots designated for perforated stubouts, dispersion, or infiltration systems, the designs shall be constructed at the time of the building permit and shall comply with the plans on file." SITE SPECIFIC CONDITIONS: The conceptual drainage plan for this short plat proposes to discharge surface water run-off into a future piping system. The future piped conveyance would be constructed and located on the adjacent property to the east under a proposed subdivision application (L04P0002). Prior to engineering plan approval, the applicant shall provide proof that assures the offsite conveyance will be constructed and located in easements where appropriate. Should the proposed offsite conveyance not be available at engineering review, and prior to plan approval the applicant shall submit a revision to this application with a new conceptual drainage plan. Since this will require a substantial change this project may be re-vest to the current SWDM (20.20.080 KKC). Report and Decision L04S0057 & L04S0058 & lang Associates, lll'llc.

We are writing in response to your Notice of Request for Additional Information dated January 19, 2006 regarding the Subject Project. Our responses are enumerated similar to your original letter and are in bold. Original County comments appear in Italics. A .. !2gg 2. ~ 4 .~ It appears as depicted on the revised site plan that the sidewalk and grading associated with Iha construction of the new road at the intersection of the entrance road with 120th A venue SE, extends beyond Iha perimeter of the existing road easement. Please provide a letter of intent from the neighbor, tax lot # 6199000125 to allow for additional easement for construction of the road. This letter must be provided prior to the preliminary approval. The actual easement must be recorded prior to the engineering plan approval. The subject intersection has been reconfigured to show all of the new improvements within the existing right-of-way or easement As shown the proposed private road accessing the short subdivision does not meet KCRS Section 2,07. The road must contain a vertical curb along its south edge per KCRS Drawing #1-010. Please revise the site plan to show this. :- The proposed road croas section has been revised to meet KCRS. The proposed project is within the designated "urban" area. The proposed thickened edge and asphalt shoulder is not permitted for the on-site road per Iha KCRS, Section 2.03 in urban areas unless a variance from the standard is obtained. The proposed road cross section has been revised to meet KCRS. The private road as proposed is acceptable however an agreement to use the cu/..de:.sac bulb by the neighboring property <TllX Lot# 6199000125) will be required. A note to this effect will be recorded on the face of the short plat. Comment acknowledged.· B. Drainage 1. The ventilation gretes for the underground RID vault cannot be located in the roadway per KCSWDM, Section 5.3.3.1. Please revise the RID design to show the grates outside the travel lane. ' Ms. Dehkordi February 28, 2006 Page2 of 3 The RID vault has been reconfigured and the ventilation grates are no long in the roadway. · 2. A 3 to 1 length to width ratio is required for the RID facility. Please demonstrate / how this is accomplished. The RID vault has been reconfigured to meet the 3 to 1 ratio requirement. 3. The Level 1 (last page) shows a pipe extending easterly from the RID facility to the street drainage system within the plat of Flevue Des Voiles, KC File L04P0002. This conflicts with the engineering 1..,,-" plans for Iha plat. A conceptual drainage plan is required demonstrating how the two drainage systems will conned!: Please coordinate this with the proponent of Flevue Des Voiles. We have contacted the applicant of Flevue Des Voiles and detennlne that they are changing their plan to show drainage connection to Yee Short Plat per easement agreement. 4. The proposed short plat depends on the completion of Flevue Des Voiles plat for drainage discharge. The proposed drainage facility along with the discharge pipe crossing the tax parcel to the aast must be completed in the event Flavue Das Voilas plat fails. A letter of intent from the tax parcel (6199000220) directly east of the site must be provided to allow construction of the discharge pipe. Letters of Intent along with a 11/lutual Easement Agreement were previously submitted to the County. The agreement has provisions for the construction of the discharge pipe. In the event Flevue Des Voiles falls (which Is unlikely}, alternative drainage systems acceptable fi:i ffie County would be proposed. If no acceptable alternative Is available, it would not be financially feal!ible for a 6 lot short plat to construct the entire drainage discharge system, then the short plat would not be constructed. Further more property ownership of Flevue Des Voiles is in the process of changing hands. The new owner, who has been working with us during the entire short plat process, has agreed to sign any necessary document when the transaction Is completed. C. Recreation Plan D. The conceptual recreation plan does not show the location of water main easement. Please be advised that no anchored or permanent structure can be placed within the water easement without approval from the Water District. A detailed recreation and landscaping plan will be required during engineering review plan. This will be a condition of approval. Comment acknowledged. Tree Replacement Please remove the proposed tree replacements from the site plan. A separate tree replacement plan will be required for review and approval during the Engineering Review phase. The tree replacement plan must be prepared showing tree species and other details and must be submitted along the road and drainage plans. This will be a condition of preliminary approval. Comment acknowledged. Other comments 1. Four copies of a conceptual drainage plan showing the items discussed above.

A letter of intent (from the neighbor, tax lot# 6199000125) is required with the next submittal indicating a willingness to provide additional easement prior to final recording. 2. A vertical curb is required along the south side of the off-site road to accommodate the ultimate 22-foot wide urban road section (KCRS Section 2.07). 3. Thickened edge and asphalt shoulder is not permitted on-site (urban area) unless variance approval is obtained (KCRS Section 2.03). A revised plan or an approved variance is required with the next submittal. 4 A private road is permitted with the agreement for the use of the CDS bulb by the neighboring property (Tax Lot# 6199000125) prior to final recording. No action is required at this time. C. Drainage, King County Surface Water Design Manual (SWDM): I. The submittal proposes an RID vault located under the cul-de-sac (CDS) bulb. The ventilation grates cannot be located in the roadway (Section 5 .3 .3 .I). Please revise the facility with the grates located outside the travel lane. 2. A 3 to I length to width ratio is required for the RID facility. Please demonstrate how this is accomplished. 3. The Level I (last page) shows a pipe extending easterly from the RID facility to the street drainage system within the plat ofFlevue Des Voiles (L04P0002). This conflicts with the engineering plans for the plat. A conceptual drainage plan is required demonstrating how the two drainage systems connect 4. Conceptual Drainage Plan: Submit 3 copies of a conceptual drainage plan, which is prepared, stamped, and signed by a professional engineer licensed in the State of Washington. 5. The letter of intent included in the preliminary TIR did not address a plat failure situation. A revised letter of intent is required with the next submittal reflecting the situation where the short plat stands alone and is required convey drainage to an acceptable discharge location. D. Revised Site Plan: 1. Drainage Improvements. Provide 3 copies of a revised site plan that addresses the orainage standards as discussed in the above section.

DearFereshteh: JAN O 9 ~--, L./ ' l..,,1., ,J Hope you had a wonderful holiday and looking forward to an even better new Yl!(ste .'Mt ilf(f=w.riting in response to your Notice of Request for Additional lnfom,ation dated August 23, 20'155reg~ing the Subject Project. Our responses are enumerated similar to your original letter and are in bold. Original County comments appear in Italics. 1. A revised conceptual plan must be prepared to show an appropriate drainage discharge location. If the discharge location will be into a sensitive area, then a conceptual discharge design must be shown: Since you plan to locate the detention vault under the road, please show that in the revised drainage plan. Road plan revised to show detention in the proposed cul-de-sac and conveyance going to the east via the existing water easement out side the area with toy structures and Into to the proposed adjacent development conveyance system. Letter of intent form the adjacent property is included in the Preliminary TIR. ~ 2. If you plan to make the proposed road a public road, then a letter of agreement from the property owner directly to the west shall be provided to allow for dedication of his property road frontage. 3. 4. There is no plan to dedicate the proposed road. That portion of the cul-de-sac containing the detention vault could be dedicated to the County if required. The conceptual road plan shows a drainage system located in the center of the road. KCRS Drawing 1-003 requires a crowned centerline unless a variance to this requirement is approved. This will be a condition of approval. Road design changed to show a crowned centerline per KCRS Standard Drawing 1- 003. Please be advised that the County will require that all toy structures be safely and permanently anchored. This may conflict with the utility District's easement. Please prepare a conceptual recreation tract showing the location of the easement, landscaping, toy facilities and any other improvements. The conceptual recreation plan must be ,, / f Ms. Dehkordi January 5, 2006 Page2 of2 reviewed by the district to determine that no conflict will exist. Soos Creek Water and Sewer in a letter had agreed to relinquish the north 20' of the existing 30' water line easement subject to final review. All toy structures that require anchoring will be located out side the remaining south 10' of the water line easement. Conceptual Recreation Space Plan is now added to Sheet 2 of 2 of the Short Plat map. 5. The preliminary TIR proposed the use of infiltration for flow control. If infiltration is to be used, a soils report must be prepared and submitted for review by DOES. The report must include the infiltration rate. Alternatively, the TIR and conceptual drainage plan may be revised to reflect a larger pond size without the use of infiltration. Infiltration at this time will not be used. The TIR calculations show detention sizing per Level 2 Flow control. Addendum 1. The current discharge point located in the Soos Creek Plat (off-site) does not appear to comply with the natural discharge location. KCSWDM Section 1.2.1 states the following: "All surface water runoff from a project must be discharged at the natural location so as not to be diverted onto or away from downstream properties. The manner in which it is discharged from the project must not create a significant impact to downhill properties or drainage systems (see "Discharge Requirements").• A SWDM adjustment will be required with the next submittal. Since the Plat of Fleuve Des Voiles does not drain to the natural discharge location. It Is antic ve Des Voiles will change their preliminary des n to be in complian i CSWDM Section 1.2.1. If they don't, it would be logl for Fleuve Des Voiles to uest a SWDM adjustment. Enclosed please find copies of documents cited in this letter and 4 copies of the revised drainage plans. We do not see the need to revise the site plan.

We will get a letter of intent from Soos Creek indicating that if the short plat receives preliminary approval they will relinquish the 20' before construction starts. No one will grant or relinquish any easement unless they are assured that the project is approved and moving ahead. I know this was the way we handled this kind of issue in the past like the drainage easement we would get from Fleuve Des Voiles when and if both project are approved. Does this make sense to you?

The area encumbered by the easement would be use for recreation tract and RID facility. The staff must be assured that the construction of both R/D and recreation tract can be done without any restriction. You have the option of placing the RID vault under the road.

Ron Speer stated that the District may reduce the 30 foot easement to 10 feet once they have an approved final plat. Unfortunately the RID facility needs to be installed prior to final recording. A revised site plan will be required, if the RID facility cannot be located as shown (within the easement). Additionally, this will include preliminary sizing calculations if the facility is altered.

KC File L04S0065 Dear Mr. Lang: We have reviewed the supplemental information submitted on July 23, 2005 and have the following comments: I. A revised conceptual plan must be prepared to show an appropriate drainage discharge location. If the discharge location will be into a sensitive area, then a conceptual discharge design must be shown. Since you plan to locate the detention vault under the road, please show that in the revised drainage plan. 2. If you plan to make the proposed road a public road, then a letter of agreement from the property owner directly to the west shall be provided to allow for dedication of his property road frontage. 3. The conceptual road plan shows a drainage system located in the center of the road. KCRS Drawing 1-003 requires a crowned centerline unless a variance to this requirement is approved. This will be a condition of approval. 4. Please be advised that the County will require that all toy structures be safely and permanently anchored. This may conflict with the Utility District's easement. Please prepare a conceptual recreation tract showing the location of the easement, landscaping, toy facilities and any other improvements. The conceptual recreation plan must be reviewed by the district to determine that no conflict will exist. 5. The preliminary TIR proposed the use of infiltration for flow control. If infiltration is to be used, a soils report must be prepared and submitted for review by DOES. The report must include the infiltration rate. Alternatively, the TIR and conceptual drainage plan may be revised to reflect a larger pond size without the use of infiltration. Please submit the following by October 24, 2005: 1. Four copies of a revisJd conceptual drainage plan 2. Four copies of a revisdd site plan if any change is proposed 3. Four copies ofa conceptual recreation plan 4.

The Ritz Trust owns the parcel known as tax lot 619900-0220 which is one of three parcels (most westerly) that comprise the Fleuve des Voiles preliminary plat application. Ms. Fanny Y. and Philip M. Yee own the property adjacent to and west of the Ritz Trust property near its northern edge. The Soos Creek Water and Sewer District, in its Water Availability Certificate of June 17, 2005, indicates that development of the Fleuve des Voiles plat will require a connection to the existing stubbed out water line on the Y ee's property. The Y ees are desirous of allowing treated storm water to drain through the future Fleuve des Voiles storm system. The Ritz Trust and the Yees have agreed to the language of a·Mutual. Easemep.t Agreement (attached). It is the intention of the Ritz Trust to sign the Mutual Easement Agreement as soon as Fleuve des Voiles receives preliminary plat'approval from King County. Encl.

Re: Yee Short Plat-Responses to Notice of Request for Additional lnfonnation King County File No. L04S0065 ' Dear Fereshteh: It is so nice to wor1< with you again. We are writing in response to your Notice of Request for Additional lnfonnation dated March 15, 2005 regarding the Subject Project. Our responses are enumerated similar to your original letter and are in bold. Original County comments appear in Italics. A. Access and Traffic: A power pole is located in the area where the new road is proposed. KCRS (Section 5.11) requires 10 feet of clearance between the obstacle (power pole) and the edge of the travel lane (or 5.5 feet from the face of a vertical curb). Because of road improvement, the power pole must be relocated unless a variance from this requirement is granted. Acknowledged. We will take care c,f this during construction. B. Drainage. King County Surface Water Design Manual ISWDMl: 1. Drainage appears to leave the site in the form of sheet flow. A drainage conveyance system must be provided to convey concentrated runoff across the down-slope properties to an acceptable_disch{Lrg5zpolnt. As proposed, this proposal will depend on the approval and construction of the proposed plat of Soos Creek, KC File L04P0002. Because of uncertainty regarding the completion and timing of the Soos Creek Plat, this proposal may have to be placed on hold until Soos Creek plat receives a preliminary approval. Otherwise, an off-site conveyance system from the site to an appropriate dischame point together with appropriate easements across neighboring properties must be secured. Letters of intent from neighboring property owners indicating a willingness to grant easements are required. We have obtained letter of intent from abutting owner and contract purchaser of neighboring property for the exchange of easements. Please see attached letters. As suggested by Mr. Bruce Whittaker, We are also Ms. Dehkordl . 4}o L... 0 ? ,-c July 20, 2005 ~ '$,¢vv Page2of~ , 17~ ~ with ~applicant of "Fleuve Des Voiles" to provide drainage discharge-connection. 2. The property contains a wetland along the east property line and a storm drainage system running just off site along the northern property boundary. Delineation of the 100 year flood plain for the wetland and drainage course Is required prior to preliminary approval. Our understanding is that applicants of the subject short plat and Fleuve Des Voiles both intent to alter the non-regu. lated wetland. Therefore, . ,,- delineatlon of the 100-year flood plain would no be useful. ..,___ ~ ~ c. Platting and Survey requirements: #'-~-· 1. The contours must be based on a field survey per KCC 19A.08.150B.2. A statement to this effect must be shown on the site plan. A copy of the topographic survey certified by Mr. Dale Oaks, PLS (Certification No. 19635) was included in the initial submittal of the subject short plat We can submit another one if the map is misplaced. ' 2. The site plan shows a fence and a shed encroachment along the south boundary of the site. This encroachment issue must be resolved prior to the final engineering plan approval. Please show how this encroachment will be resolved. 3. These encroachments are recent and do not have adverse possession rights. Ms. Yee had granted property owners temporary easement for the encroachments. Grantees are required to relocate the encroaching elements on demand (AF# 20041130000990 & 20041130000991 copies enclosed). As proposed, the recreation tract and the detention vault will be located within a 30-foot water main easement (recording No 7810020168). This easement must be relocated. A letter of agreement from the easement holder to allow relocation or relinquishment of the easement must be provided. Soos Creek Water & Sewer District does allow the use of the easement for vault and/or recreation spaces. The ~nly use the south 10' of the easement and the detention facility!(most likely a1 detention tank) would fit within the remaining 20'. Letter from~is forth coming. Please provide a copy of easement AF# 711006608 to show that it allows the required road improvement within the easement. This item was clarified by Mr. Pat Simmons in his email dated 4/1/05 (attached). In addition, the Yees had reserved an easement when they sold the Tax Parcel 619900125 (AFN 8203220316 copy enclosed). .. i Ms. Dehkordi July 20, 2005 Page 3 of3 D. Recreation Tract The proposed combined drainage and racraation tract must allow for a full improvement of the recreation tract as an active recraation area together with landscaping and other related improvements. If other design constraints require the relocation of the vault, it will be preferable to locate the recreation tract where Lot 2 is proposed. The district has Indicated that we can use the easement for recreation as long as nothing Is anchored to the ground. Letter from the District is forth coming. Enclosed please fi ies of documents cited in this letter. We do not see the need to rev~eftie site planafthis-Um . e are working with_tlJ.upplicant of Fleuve Des Voiles on_the Co~ptual Drainage Plan. t will be submitted_aS-soon-as.they are revised.

Enclosure Cc FannyYee February 9, 2005 Dept of Development & Environmental Services Land Use Services Division 900 Oakesdale Avenue SW Renton WA 98055-1219 RE: Application L04S0065 Dear Sirs: We are 17-year property owners just south of this property and have several concerns: 1. .96 acres is not an acre. Why is there an application for 6 homes? Our cul-de-sac is about 2.5 acres, and only 8 homes. We purchased property because of the view we have (for now) and the amount ofland that each homeowner owns. We dispute the necessity of 6 homes on this property. They will be too close together and they probably will be too large. 2. This property, along with ours, is on the hill on the west side above Soos Creek. We are concerned about the amount of water that flows underground all the properties in this area and the amount of potential pollution of Soos Creek. Although we are on the hill, we are not at the high point of the hill, and there can be a tremendous amount of water flow underground during a wet season. Topically, we've had some driveways flood/washout in past years; one home lost their basement to flooding several years ago. The property involved in this application does not have evergreen trees on it, which, we understand, means a higher water table. More houses, more water problems. On the south side of SE l 92"d, we know of a house that ended up with a "sink hole" in their front yard. They just happen to be east of a newer cul-de-sac with 25 homes in it. Isn't it possible the sink hole was caused by excess water flowing and being disturbed underground from the construction of all those homes? 3. The traffic congestion is getting worse. There is a new area tinder construction with 58 homes in it -10 feet between each house. Calculating 2 vehicles per house, and then counting all the applications in process in the one square mile around us, we're looking at probably 300 more vehicles and pollution from them on our roadways. Already, we find it is more difficult to get out on our major road from our cul-de-sac entrance. It used to be waiting for a car to go by; now it can be a dozen or more. Used to take just a minute, now can take 2-5 minutes or more! Other than Benson Road, all our roads are 2 lanes and can barely handle the traffic as it is. We don't want more lanes, we want less traffic! 4. And what about fire safety between homes? With only IO feet between houses, how can a fire department properly protect the neighborhood? 5. We have paid high property taxes in King County for this urban property we own fo~ all these years, and we highly dispute what King County has done to our zoning rights. The last meeting we were notified of and attended, this area was zoned at one house per half acre. We have had no other notification, but it appears that somehow, these properties were changed to R6 zoning and those of us with more land highly disapprove of this dense construction that is being allowed. This particular application appears to indicate 6 homes per half acre? What kind of zoning is that? 6. We are NOT city dwellers. Ifwe had wanted to live close to our neighbors, we would have moved within the city limits! What about OUR property rights and OUR quality of life? We can understand people wanting to develop their land, but WHY does it have to be so dense?

B. Access and Traffic: A power pole is located in the area where the new road is proposed. KCRS (Section 5.11) requires I 0 feet of clearance between the obstacle (power pole) and the edge of the travel lane (or 5.5 feet from the face of a vertical curb). Because of road improvement, the power pole must be relocated unless a variance from this requirement is granted. Drainage, King County Surface Water Design Manual (SWDM): I. Drainage appears to leave the site in the form of sheet flow. A drainage conveyance system must be provided to convey concentrated runoff across the down-slope properties to an acceptable discharge point. As proposed, this ro osal will depend on the approval and construction of the proposed plat of Soos Creek, KC File L04P0002. Because of uncertainty regarding the completion and timing of the Soos Creek Plat, this proposal may have to be placed on hold until the Soos Creek plat receives a preliminary approval. Othe!:Wise, an off-site conveyance system from the site to an ap2!:9priate discliarge point together with appropriate easements across neighboring properties must be secured. Letters of intent from neighboring property owners indicating a willingness to grant easeinents are riquired. 2. The property contains a wetland along the east property line and a storm drainage system running just off site along the northern property boundary. Delineation of the I OO_year_flo.oJ)_pJaiE_for the wetland and drainage course is required prior to preliminary approval. C. Platting and Survey requirements: I. The contours must be based on a field survey per KCC 19A.08.150B.2. A statement to this effect must be shown on the site plan. 2. The site plan shows a fence and a shed encroachment along the south boundary of the site. This encroachment issue must be resolved prior to the final engineering plan approval. Please show how this encroachment will be resolved. 3. As proposed, the recreation tract and the detention vault will be located within a 30-foot water main easement (recording No 7810020168). This easement must be relocated. A letter of agreement from the easement holder to allow relocati~n or relinquishment of the easement must be provided. 4.

The following are a list of my concerns: I. The reference to relevant environmental documents is checked "Not applicable". The area under proposed development has previously failed a water percolation test, hence the need for sewer, and the parcel to the North floods during heavy rain. I am concerned that environmental impacts may not be entirely investigated. Is this true? 2. I am concerned about the ensuing removal of trees and the impact, plus the type and location of replacement trees. 3. I need to know how the.impact of the slope and grading will affect my property. 4. I would like to know more about the location of sidewalk improvements and/or streetlights, and postal deliveiy impact. 5. 1 am concerned about traffic patterns.

The site is undeveloped and consists primarily of an upland deciduous forest. Topography on the site gnerally slopes gently down from west to east. One small wetland (Wetland A) was identified along the eastern property boundary (Figure 1) and was delineated utilizing the methodology outlined in the 1997 Washington State Wetlands Identification and Delineation Manual. Wetland A consists of a small (175 s.f. on-site) isolated shallow topographic depression that extends slightly off-site to the east. Vegetation within the on-site portion of the wetland was generally sparse and consisted primarily of one small black cottonwood (Populus trichocarpa) and one small Oregon ash (Fraxinus latifolia). The remainder of the wetland consisted of surface stained duff, indicating early seasonal ponding. , Hydrology within the wetland was assumed during the field investigations based ofi. th 72'> presence of hydric soils. l!y I!;;' (/} Attachment A contains data sheets prepared for a representative location in both tti[er, /t f /if IC" upland and wetland.

The project site is comprised of three parcels; ( Parcel # 6199000220, 6199000240, 6199000260). The project site is dominated by mature and sub-mature forest, with single-family residences, managed and maintained lawns, and unmanaged portions. Onsite assessment of the project site following the procedures outlined in the Washington State Wetlands Identification and Delineation Manual (Wash. Manual) and the Corps of Engineers Wetlands Delineation Manual (1987 Manual) resulted in the identification of two areas that exhibited hydric soils, wetland hydrology, and hydrophytic vegetation consistent with the established criteria of both the Wash. and 1987 Manuals. This assessment, completed in accordance with King County regulations, included an evaluation of the function and value rating for the identified wetlands, a classification of the wetland following the U.S. Fish and Wildlife methods, and an identification of the standard King County buffer width required for these wetlands. · WETLAND SIZE CLASSIFICATION KING ·FUNCTION STANDARD ONSITE (USFWS) COUNTY AND VALUE BUFFER WIDTH (square RATING RATING feet) A Offsite -PFOE 1 High 100 ft. Buffer onsite B *998 PSSC 3 non-Low Not regulated reaulated •connotes wetland continues off-site PFOE paluslrine, emergent, seasonally flooded PSSC paluslrine, shrub-scrub, seasonally flooded/saturated . The U.S. Army Corps of Engineers and King County, as well as a number of other local, state, and federal agencies, regulate activities in and around identified wetland and drainage corridor areas. Such regulations focus on the avoidance of adverse impacts to wetlands, streams, associated buffers and the mitigation of such impacts that cannot be avoided. King County has established criteria to categorize wetlands for purposes of regulation and the establishment of buffers. In addition, King County allows a limited amount of alterations to wetlands (i.e. isolated wetlands, roadway crossings) provided such impacts are mitigated pursuant to an approved mitigation plan. The Selected Action Plan of the Soos Creek Plat project site focuses on the creation of independent lots suitable for the development of single-family homesites consistent with the King County Comprehensive Plan. • • \ I ® King County Road Services Division Department of Transportation 201 South Jackson Street Seattle.

We have reviewed your submittal, and with the following conditions and additions, approve it as submitted: 1. The equipment (structures, benches, picnic table, etc.) shall meet at a minimum, Consumer Product Safety Standards and be appropriately anchored. 2. Walkways/Trails shall be installed from the sidewalk to the play areas. Walkways shall be constructed of a material and grade that is Americans with Disabilities Act (ADA) accessible. 3. The fence along the perimeter of the tract shall be backed by either chain link or low plantings to alleviate any potential conflicts between users of the recreation space and vehicles (i.e. balls rolling into street, etc.). 4. The grass-crete or other alternatives for access to the stormwater facility must be approved with the engineering plans. If this surface is not approved, a revised recreation plan will be required. In the event a solid surface (i.e. asphalt, concrete, or similar) is required for the drainage facility a revised plat layout may be required, as the access to the drainage facility and associated appurtenances are not counted toward the recreation space requirement. 5. In the event the engineering plans, soil amendment, street tree and/or significant tree plans result in modification/revisions to the recreation space plan, a revised recreation plan will be required. The landscaping and recreation space improvements (i.e. play structures) must be installed and inspected or a performance bond posted, prior to plat recording. The amount of the bond'has been established at $40,000. This includes landscaping, equipment, surfacing materials, fencing, etc. The bond amount includes a thirty- percent contingency, as well as the requirement for the wood fence to be backed with chain link or additional shrubbery/low plantings along the fence. Note, this approval does not include soil amendment plan, street trees or significant trees. This will be reviewed in conjunction with the engineering plans. An inspection fee is also due prior to recording. This fee covers the cost of an installation inspection and a maintenance inspection. The amount of the inspection deposit will be determined by the Land Use Inspection Section (LUIS). If a performance financial guarantee is posted, the improvements must be installed within two year's from the date of recording. At the time of inspection by the Land Use Inspection Section, if the improvements are fully installed per the approved plan, the performance financial guarantee may be reduced. Enclosed is a copy of the approved plans for your records. If you have any questions, please call me at (206) 296-7167. If you have questions regarding the financial guarantee please contact Carol Rogers, Finance Section at (206) 296-7250. Questions regarding the inspection process may be directed to the Land Use Inspection Section (206) 296-6642.

To implement the engineering review process, the Department of Development and Environmental Services (ODES) has implemented a program for managing certain types of permit applications to provide customers with an enhanced level of customer service. The Project Management program seeks to provide customers with increased predictability for the permit process and better accountability from County review staff. For permit applications under Project Management, a project manager is assigned to the permit to facilitate communication with the applicant and provide a fee estimate to cover the anticipated scope of review. The project manager will also monitor and manage the permit application throughout the review process to ensure review schedules remain in line with performance standards and the overall work hours are within the range of estimated fees for the project. Your application was received by our office on April 28, 2008 and will be processed by a Project Manager. The enclosed information provides a summary of the fee estimate for the anticipated work disciplines and fee estimate revisions which may affect the permit fees. Please return the signed Acknowledgment Form, page 2 of the enclosure, to my attention at the address specified in the letter head. Failure to return the Acknowledgement Form and payment of the estimated fee within 17 days of the date of this letter may result in the suspension or cancellation of the application. All fee payments shall be made to the cashier in the DOES permit center using activity number L08SR020. Robert Johnseine May 7, 2008 Page2 The enclosed fee estimate includes the scope of work for engineering plan review only and does. not evaluate other final plat requirements such as construction inspection and review of plat recording documents. If you have any questions regarding the permit fees or other aspects of the review process, please contact Peter Dye via email pete.dye@kingcounty.gov or by telephone at 206-296-7185.

Failure to do so will result in the loss of your right to dispute and appeal the estimate and may result in cancellation of the application. Fee Estimate Revision Applicants are responsible for all fixed fees, reported hours performed in reviewing submittal materials and processing, up to the fee estimate. Changes in the scope of the project review will result in a revised review fee estimate. Fee estimates are based on information submitted to DOES by the applicant prior to finalization of the permit application. In addition, estimates are determined by utilizing historical data gathered from projects of similar type, size, and scope. The fee estimate will be the maximum fee charged unless the scope of the project changes. Should fewer hours be required to complete the review, then the applicant may receive a refund for those hours. If items are identified that are not originally disclosed, a new estimate may be required. Applicants will be responsible for any additional hours identified in a new estimate if: I. The applicant fails to provide accurate, complete, or timely information. 2. The applicant fails to disclose a site or development issue that creates the need for additional review that could not have been reasonably anticipated by the Project Manager during the preparation of the previous Fee Estimate. 3. The applicant changes the scope or design of the proposal, creating the need for additional review that could not have been reasonably anticipated by the Project Manager during the preparation of the previous Fee Estimate. 4. The applicant fails to complete the construction of the project in a timely manner, creating the need for additional review, unanticipated by the Project Manager during the preparation of the previous Fee Estimate. 5. The applicant files an appeal and the Fee Estimate did not anticipate an applicant appeal. 6. The applicant makes a request to separate the review of the project into distinct phases .7. There has been unauthorized construction on the property, including, but not limited to, clearing or grading, or an associated code enforcement case is opened. 8. The King County Council modifies permit fees. 9. The project is modified, such that there is a change in the building valuation and the resulting building valuation fees. Keeping review fees at or below the fee estimate will depend on the applicant's commitment to complete the process review. This commitment should include submitting materials which address all County codes, policies, previously approved conditions, and responding to the County's request for corrections or additional information in a timely manner, notto exceed 90 days. 0 Accept the Fee Estimate 0 Dispute the Fee Estimate Applicant/Owner Name (print) Applicant/Owner Name (signature) Date ' Page 2 tQ King County INFORMATION ON PROJECT MANAGEMENT STATEMENTS, BILLING/PAYMENT REQUIREMENTS, INSTALLMENT PAYMENT PLANS, ACKNOWLEDGEMENT, APPEALS AND FINANCE CHARGES Your application is being reviewed under the Project Management program, you will be provided a budget estimate that is based on historic averages and the information you provided with the application.
