REINFORCED WALL FILL MATERIAL SHALL BE PLACED IN MAXIMUMS-INCH LOOSE LIFTS ON THE GEOSYNTHETIC REINFORCEMENT. 2. THE GEOSYNTHETIC REINFORCEMENT SHALL BE PRETENSIONED BY HAND TD REMOVE WRINKLES. TENSIONING IS USUALLY FACILITATED BY THE USE OF STEEL STAKES. APPLY CONSTANT TENSION TO EACH SECTION OF GEOSYNTHETIC REINFORCEMENT UNTIL SOIL FILL HAS BEEN PLACED. SOIL FILL SHALL BE PLACED, SPREAD, AND COMPACTED IN SUCH A MANNER THAT PREVENTS THE DEVELOPMENT OF WRINKLES AND/OR MOVEMENT OF THE GEOSYNTHETIC REINFORCEMENT. 3. ONLY HAND-OPERATED COMPACTION EQUIPMENT SHALL BE ALLOWED WJTHIN 3 FEET FROM THE TAIL OF THE MODULAR CONCRETE UNITS. 4. IF POSSIBLE, SOIL FILL SHALL BE PLACED FROM THE WALL FACE OUTWARD TO ENSURE THAT THE GEOSYNTHETIC REINFORCEMENT REMAINS TAUT. SOIL SHALL BE PLACED IN UNIFORM LIFTS. 5. TRACKED CONSTRUCTION EQUIPMENT SHALL NOT BE OPERATED DIRECTLY ON THE GEOSYNTHETIC REINFORCEMENT. A MINIMUM FILL THICKNESS OF 8 INCHES IS REQUIRED PRIOR TO OPERATION OF TRACKED VEHICLES OVER THE GEOSYNTHETIC REINFORCEMENT. TURNING OF TRACKED VEHICLES SHOULD BE KEPT TO A MINIMUM TO PREVENT TRACKS FROM DISPLACING THE FILL AND DAMAGING THE GEOSYNTHETIC REINFORCEMENT. 6. IF IN ACCORDANCE WITH MANUFACTURER'S RECOMMENDATIONS, RUBBER-TIRED EQUIPMENT MAY PASS OVER THE GEOSYNTHETIC REINFORCEMENT AT SLOW SPEEDS, LESS THAN 10 MPH. SUDDEN BRAKING AND SHARP TURNING SHALL BE AVOIDED. 7. SURFACE DRAINAGE DURING AND AFTER CONSTRUCTION OF THE WALL SHALL BE PROVIDED TO MINIMIZE WATER INFILTRATION IN THE REINFORCED SOIL ZONE.

During the approval of L04V013, East Renton and Rosemonte had different developers. East Renton and Rosemunte now have a single developer and are undergoing a singular Engineer Review under LUSD file number L07SR054. 4. The East Renton and Rosemonte subdivisions are located in the Honey Creek subbasin of the May Creek basin. Both sites are subject to the Level One flow control and Basic waler quality requirements of the 1998 KCSWDM. 5. The proposal h~ to accommodate all stormwater flows from the development of East Renton (less wetland recharge) and Rosernonte to a single shm·ed drainage facility in the Rosemonte plat. This approach would revise the diversion adjustment (L02V0089) previously processed to divert flows from the south basin area into the north basin area of Rosemonte and expand the previously approved shar~ drainage facility adjustment, L04VOl03 to include stormwater flows from the East Renton south basin area. I. The release rates for tl1e detention fucility will be based on the tributary area being directed lo the facility. 2. The volume for the detention facility will be based on all flows directed to the facility at full development under CUffent zoning. 1'he allowed release rate will be reduced by any undetained flows that would bypass the proposed subdivision drainage facilities. The detention volume shall be sized using the Level One flow control standard in the 1998 KCSWDM. A 10 lo 20 percent volumetric factor of safety must be applied to all stom1 events requiring detention. The design Technical Information Report shall state the factor of safely selected and the basis of that detennination. 3. Water quality facilities must be sized based on the entire proposed subdivision draining to the facilities including any required frontage improvements. 4. All onsite or offsite drainage facilities must be located in a public right-of-way or storm drainage tract dedicated to King County. 5. The developer of the shared drail . ge-facility is responsible for any cost sharing agreements that may need lo be s t up as part of the implementation of the shared facility plan. 6. Engineedng plans for both the E, ·t Renton and Rosemontc subdivisions shall note this approved shared facility plan. 7. If the two projects are phased sc ately in time, the shared drainage facility must be constructed first and operational efore any lots tributary to the facility can be recorded. 8. If there is a change of design sta <lards or project design that requires modification ofthe shared facility design. an update o the shared facility plan shall be provided as part of the trailing project's engineering rev ew submittal. 1f you have any further questions regardi g the SWDM adjustment or the d~sign requirements, please contact Claire Jonson by telephon at 206-296-6641. s· cerely, !W1~~ 1m Sm1d rs.

Based o'n these findings, we hereby approve this adjustment to allow the diversion of runoff to a shared drainage facility with shared facility plan for the East Renton and Roscmonte subdivisions with the following conditions: May22,2008 Jennifer Reiner Carnwest Development 9720 NE l20th Plaee Kirkland, WA 98034 Richard Tomkins, P.E. Triad Associates 12112 115th Ave NE Kirkland, WA 98034 RE: East Renton and Rosemonte Subdivisi.ons: 1998 KCSWDM Adjustment Request (File No. L08V0039) Dear Applicant and Engineer: The Department of Development and Envirornriental Services (DDES), Land Use Services Division (LUSD), Site Engineering Review Section, has _completed review of the adjustment request for the East Renton and Rosemonte subdivisions. This request addn:sses the 1998 King County Surface Water Design Manual (KCSWDM) Section 1.2.1, Discharge at the Natural Location, and Special Condition No. 1, Section 1.3.J, Other Adopted Area-Specific · Reqttlrements and the Shared facility Plan Guidelines published in a memo dated September 15, 1999 describing the Shared Facility Plan approval process. Our review of the information provides the following findings: 1. The East Renton subdivision is located on the west side of 148th Avenue SE at approximately SE 120th Street. The 66 lot, 19.6 acre, East Renton subdivision has preliminary approval under LUSD file nwuber L02P0005. The East Renton subdivision had previously processed 1998 KCSWDM adjustments L02V0089 for a di version to consolidate subbasin flows into a single, on-site facility, and L04VOI03 for a shared drainage facilility. 2. The Rosemonte subdivision is located adjacent to East Renton along the north property line. The 25 lot, 19.3 acre, Rosemonte subdivision has preliminary approval m1der LUSD file number L03POOl8. 3. During the approval ofL04V013, East Renton and Rosemonte had different developers. East Renton and Rosemonte now have a single developer and are Wldergoing a singular Engineer Review under LUSD file number L07SR054. 4. The East Renton and Rosemonte subdivisions are located in tht: Honey Creek subbasin of the May Creek basin. Both sites are subject to the Level One flow control and Basic water quality requirements of the 1998 KCSWDM. 5. The proposal is tu acconunodate all stormwater flows from the development of East Renton (less wetland recharge) and Rosemonle to a single shared drainage facility in the Rosemonte plat. This approach would revise the diversion adjustment (L02V0089) previously processed to divert flows from the south busin area into the north basin area of Rosemonte and expand the previously approved shared drainage facility adjushnent, L04V0103 to include storm water flows from the East Renton south basin area. 1. The release rates for the detention facility will be based on the tributary area being directed to the facility. 2. The volume for the detention facility will be based on all flows directed to the facility at full development under current zoning. The allowed release rate will be reduced by any undetained flows that would bypass the proposed subdivision drainage facilities. The detention volume shall be sized using the Level One flow control standard in the 1998 KCSWDM, A 10 to 20 percent volumetric factor of safety must be applied to all storm events requiring detention. The design Teclmical Information Report shall state the factor of safety selected and the basis of that determination. · 3. \Vater quality facilities must be sized based on the entire proposed subdivision draining to the facilities including any required frontage improvements. 4. All onsite or offsite drainage facilities must be located in a public right-of-way or storm drainage tract dedicated to King County. 5. The developer of the shared drai . ge-facility is responsible for any cost sharing agreements that may need to be s t up as part of the implementation of the shared facility plan. 6. Engineering plans for both the E st Renton and Rosemonte subdivisions shall note this approved shared faeility plan. 7. If the two projects are phased se ately in time, the shared drainage facility must be constmcted first and operational efore any lots tributary to the facility can be recorded. 8. If there is a change of design sta <lards or project design that requires modification of the sh~~d facility ~esig~, an update o the.shared facility plan shall be provided as part of the trailing proJect s engmeermg rev ew submittal. If you have any further questions regardi g the SWDM adjustment or the design requirements, please contact Claire Jonson by telephon at 206-296-6641. ?JJr-U{~ tm Sand rs, P.E. Mark Bergarn, P.E.

Triad Associates 12l l2 ll5"' Ave NE Kirkland, WA 98034 RE: East Renton and Rosemonte Subdivisions: 1998 KCSWDM Adiustment Request {File No. LOSV0039) Dear Applicant and Engineer: The Department of Development an<l Environmental Services (DDESJ, Land Use Services Division (LUSD), Site Engineering Review Section, has .completed review of the adjustment request for the East Renton and Rosemonte subdivisions. This request addresses the 1998 King County Surface Water Design Manual (KCSWDM) Section 1.2.1, Discharge at the Natural Location, and Special Condition No. !, Section 1.3.1, Other Adopted Area-Specific Requirements and the Shared l'acility Plan Guidelines published in a memo dated September 15, 1999 describing the ShITTed Facility Plan approval process. Our review of the information provides the following findings: 1. The East Renton subdivision is located on the west side of 1481h Avenue SE at approximately SE 120th Street. The 66 lot, 19.6 acre, East Renton subdivision has preliminary approval under LUSD file number L02P0005. The East Renton subdivision had previously processed 1998 KCSWDM adjustments L02V0089 for a diversion to consolidate sub basin flows into a single, on-site facility, and L04 VO 103 for a shared drainage facilility. 2. The Roscmonte subdivision is located adjacent to East Renton along the north property line. The 25 lot, 19.3 acre1 Roscmonte subdivision has preliminary approval under LUSD file number L03POOIS. 3. During the approval ofL04V013, East Renton and Rosemonte had difforent developers. East Renton and Rosemonte now have a single developer and are undergoing a singular Engineer Review under LUSD file number L07SR054. 4. The East Renton and Rosemonte subdivisions are located in tlie Honey Creek subbasin of the May Creek basin. Both :,ites are subject to the Level One flow control and Basic water quality requirements of the 1998 KCSWDM. 5. The proposal is to accommodate all storrnwater llows from the development of East Renton (less wetland recharge) and Rosemonte to a single shared drainage facility in the Rosemonte plat. This approach would revise the diversion adjustment (L02V0089) previously processed to div·ert flows from the south basin area into the north basin area of Rosemonte and expar1d the previonsly approved shared drainage facility adjustment, L04V0103 to include stonnwater flows from the East Renton south basin ai·ca. 2. The volume for the detention facility will be based on all flows directed to the facility at foll development under current zoning. The allowed release rate will be reduced by any undetained flows that would bypass the proposed subdivision drainage facilities. The detention voh1me shall be sized using the Level One flow control standard in the 1998 KCSWDM. A 10 to 20 percent volumetric factor of safety must be applied to all storm events requiring detention. The design Teclmical Information Report shall state the factor of safety selected ,md the basis of that detennination. 3. Water quality facilities must be sized bm;;ed on the entire proposed subdivision draining to the facilities including any required frontage improvements. 4. All onsite or offsite drainage facilities must be located in a public right-ol~way or storm drainage tract dedicated to King County. 5. The developer of the shared drai . ge facility is responsible for any cost sharing agreements that may need to be s plan. t up as part of the implementation of the shared facility 6. Engineering plans for both the fr ·t Renton and Rosemonte subdivisions shall note this apf!roved shared facility plan. 7. If the.two projects are phased se ately in time, the shared drainage facility must be constructed first and operational efore any lots tributary to the facility can be recorded. 8, If there is a change of design st <lards or project design that requires modification of th~ shar~d facility ?esign, an ?pdate o the shared facility plan shall be provided as part of the trailing proJect s engmeenng rev ew submittal.
