Recitals The Owners own real property in the City legally described on Exhibit A, attached. The Owners have submitted an application for building permit(s} and/or a Temporary Use Permit to site model homes on the real property prior to recording of a short plat or final plat. Because changes to the short plat or final plat may be necessary after the time owners build the model homes, rendering the homes illegal, there is some risk in building the model homes. In view of the risks inherent in construction of buildings in advanceof plat recordation, the City requires the owner to execute an indemnification agreement prior to any model home construction activities. Agreement The parties agree to the following 1. The City authorizes the Owners to do the work as described in the Temporary Use Permit application # __________ once building permits have been obtained. 2 .. The Owners assume the risk that the model home(s} must be removed or reconfigured and therefore release and discharge the City and its representatives from all known and unknown losses, claims, damages or causes of actions which the Owners have or may have relating to buildings or structures· authorized by the Temporary Use Permit. 3. As a condition of granting Owner permission to construct model homes, Owner agrees to indemnify, defend and hold the City of Renton harmless from any claims or liens that may be exerted against the property as a result of construction of model homes and use of the unrecorded plat of ~tlWSI:; /)Mll~ 1. . 4. Owner understands and acknowledges that, should the model home construction not comply with the proposed lot configuration of the final plat, that no variances to development standards for either the lots or the homes may be granted as such a situation would be considered a "self -induced hardship". 5. Owner(s} further acknowledges that they understand that any construction begun prior to recording of the final plat must be in compliance with all City Zoning and Subdivision requirements (e.g. setbacks, lot coverage, etc.) or removed prior to recording of the final plat. If the final plat is not recorded prior to the expiration of the Temporary Use Permit, Owner acknowledges thaUhe homes must be removed unless complying with all applicable code requirements (e.g. one home per lot, etc.). 6. Applicant will also provide an Abatement Agreement and a security device acceptable to the City to ensure removal of any structures not in compliance with the City regulations at the time of expiration of the Temporary Use Permit and understands construction of the model homes is at Owner's own risk. nEC ~ ~ 100~ Page 1 of 2 http://WW~.ci~Yon.wa.us/pw/devserv/fonns/Planning/tempuse.doc 11 /22/04 10 Release and Indemnification Agreement (page 2 of 2) 7.

The site is approximately 30 acres. The project proposes to construct 136 lots with the supporting roads, curb, gutter, sidewalk and utilities. There is a 2.1 acre area in about the middle of the site that is not part of the project. See Figure 2-Site Plan, for the overall site plan. The existing site is a 50/50 mixture of forest and pasture with individual homes and outbuildings scattered through out the property. See Figure 3-Landcover for a scaled aerial map of the property. The City of Renton requires Level 2 flow control and the Basic Water Quality menu for the site as specified in the 1998 King County Surface Water Design Manual. The on-site generated runoff will be conveyed to a combined detention! water quality pond in the southwest corner of the property. All drainage discharge from the pond will be conveyed via pipe to Maplewood Creek as shown in the plan. I I I I I I I I I I I I I I I I I I I I 9/22/2004 ll. OFF-SITE ANALYSIS Upstream Tributary area The site is located at the top and edge of a drainage basin. There is approximately 5.1 acres of offsite tributary area. There is also a 5.5 acre portion of the site that flows to the east that will be redirected to the west (called East Basin). This area has seen resent stonn drainage improvements to mitigate flooding problems along the adjacent stream corridor. This project proposes to relieve some of the still remaining flooding problems by redirecting the runoff from this 5.5 acre portion back to the west and into the projects detention! water quality pond. Included, in the Appendix of this report, is a complete King County Water and Land Resources Division complaint list for this area. Three areas are tributary to the proj ect. A 2.10 acre group of parcels in the middle of the site (TA2), a 2.46 acre parcel on the north end (TAl) and a 0.56 acre parcel at the south end (TA3). The tributary areas will flow through the pond but it is assumed it will have its own detention and water quality facility when it is developed. See below for a detailed narrative of the remaining downstream system. Downstream Analysis See Figure 6-Downstream Hydrology, as an aid in the following discussion. On January 14, 2004 A site visit-was conducted. The weather was cool, 45 degrees and overcast. The week prior to this site visit was moderately rainy and cold. The downstream portion of the investigation began at the southwest comer of the project where the proposed outfall from the pond will be. This area is a steep, forested slope. The stream channel the area of the proposed pond outfall is I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I 9/22/2004 wooded and steep. The energy dissipater proposed at the edge ofthe Maplewood Creek will be located on the opposite side of the stream from an existing structure that conveys stormwater from the plat to the west along Bremerton Ave. This outfall is about 30-feet upstream of the one proposed. On the day of this report the stream was flowing, the water surface was about 10 feet wide with gravel and large cobble-stones visible. Slow pools of water show signs of sediment deposition and steeper stream channel areas show signs of bank erosion and scour. The stream channel is heavily wooded with alders and low brush in this area. Approximately 0.3 miles downstream of the proposed pond the stream valley opened wider and this stream combines with a stream that flows from the east. This stream conveys the flow from the eastern 5.5 acres ofthe project site. From this location the stream valley opens even more. Isolated pools of sediment deposition and steeper areas of erosion exist along the channel here. This continues until 0.8 miles from the discharge point where the stream enters a pond at the North-East edge of Maplewood Golf course. "- Downstream Analysis -Special Note The drainage area located on the eastern edge of the property receives approximately 5.5 acres of runoff from the project site as detailed in the first paragraphs of this section. This area, known as Puget Colony Homes, has had significant storm water runoff complaints (see King County Drainage Complaint Map and individual complaint reports) received by the county both before recent conveyance system improvements and after. Rather than adding flows to this problematic basin and exacerbate the situation, this project proposes to remove the 5.5 acres from this basin and redirect it to the proposed pond which discharges to a basin with more capacity. This redirecting of storm water may reduce the level of problems in the Puget Colony Homes project. Note both these basins combine approximately 0.3 miles downstream ofthis project.

Thank you for your November 25. 1990 1 e'tter expressi n9 your concerns about surface water problems on the street in f~on~ of your property. The Surface Water Management Division has completed the "Yahn Drainage Study, Phase 11. II The fi rst phase of th is study ; dent; fi ed all of the prob 1 ems wi th this drainage basin and the magnitude of those problems. The Pnase II por~ion of the study identified so1utions and recommendations for solving these problems. The study has recommended three areas which must be addressed ~o solve the prDblem on your street: (1) to provide an adequate upstream storm- water. s~orage facility; (2) to increase the capacity of the drainage system in the basin; and (3) to provide erosion protection of the downs'tream natural chan- nel and reduce the"s'iltation of the Cedar River. Base'd on the results of the· study, the proposed solu'tion to the flooding and I erosion proble~ will require a Capital Improvement Program.(CIP) project ,... ;' est~m~~~~ i1t@O~t9Q~. !h'l' Sf)l)r,o~ect_ chansnotfbe' stwartedMuntil all De~i ~t~l'Ig ChIP ~f; .....

All available funds are I I I being used to address these problems and, ",rithou't additional funding'. your CIP project cannot be cons'tructed in 1991. . The Surface Water Management Division will consider this CIP proj~c~ for funding 2S part of a new five-year CIP beginning ir. 1992. This S300.000 project will likely be high on the priori~y list. Piease be aware, however, that there are unmet CIP project needs ; n K i n9 County estimated at over S80 mi" fon. Given this demand for projects, this project must be evaiuated along side other com- peting projec~s and scheduled accordingly. ". ¥-;..~ •. NO.415 P.8/19 , DEC. 22. 2003 'I~n n i 10:41AM I , • -!

The ditches appear 'to be clear of debris and are functioning correctly. Tne reason the area floods is due to a lack of capacitj in the pipe system that connects 'to the open ditcnes. These pi pe systems are on K 1 n9 County ri gnt-of -way and Off private property. To correCt 'the hck of capacity in thi s system, it will require the CIP prOjt!ct t;iat was identified in our engineering study. The issue or the two mobile homes on one site is a temporary condition. Tne second mobile home was installed because of a medica' hardship. Before this was allowed by the Bui1ding and Land Development Division. a notice was sent to neighbor-jng property owners for their comments. Tne public Health Department approved the septic ~ank system for these mobile homes.-The Surface ~ater Management Division will investigate the filling of the open ditch to determine if the drainage has been.i~pac~ed by the site changes. Thank you again for bringing your concerns to ~ attention.

In our June meeting here in Puget Co~ony, I agreed to get signatures from owners of two 1ots. Those Signatures wou2d permit County repair vehic1es/personnel on the respective lots. Mr. Leonard recieved a fax from Randy Snow, SWM, on 7-18. The fax was the forma, wbich the property owners had only to sign. I brought them I r01ll'l.d and got them Signed and mailed back on 7-19. These Signatures were obtained by me 1n good faith, lacking information which is readil.y avail.ab~e to County empl.oyees, which sta.tes names and addresses o~ legal owners. Nov, it seems, one o~ the signatures I obtained was not, in £act, a. property owner's. With the hel.p of Mr. Snow I got the name and address of the owners, sent them a registered ~etter explaining the situation, enclosed the 1'oDlS to sign and 1.nstru.cted them to return them to Mr. Snow a.t SWM. I recieved a cal.l from Barbara Orosby, one of the owners, this ·afternoon. (The other owner is Chris Crosby; addres~: P.O. Box 2851, R~ton, WA 96056.) She stated that she wanted to cooperate, but did not want to sign the papers because the outfit which is installing the drainfields told her to give no one access to her property. I pointed out that the County agreed to return the property to its original condition, and told her that if she refused to sign, she might prOVide a cause of action for the County or for us in the ne~ghborhood.

Here's Info on a c;lralnage complaint was reported to me at 14013 SE 133rd SL Cindy Dearmlt lsp?) called reporting that her h~se and yard has setued. They relavsled the house last summer and now it's settled again. Cabinets pulled away from walls, walls cracking, fenceposts out of the ground, etc. She says the problems started this past year. Her husband thinks It might be the result of a small project that we had Jeff Jacobson do for their neighbors last year. We had a small drain line installed that outlets to a basin near their house. Her husband thinks the basin is "broken", so the watar doesn't have anywhere to go. I think Jeff WOUld be the ideal candidate to investigate this one since he's already familiar with the area. Whoever goes can talk to me first We have a project planned for the next couple months (pending funding) behind the house in question~ but it won't solve this problem (though it may help slightly) •.

HYDRAULIC ANALYSIS The drainage analysis was modeled using the King County Runoff Time Series (KCRTS) software version 4.2. The site soils are Alderwood (AgC), KCRTS group, Till. The site is located in Sea-Tac rainfall region with a sale factor of 1.0. See the Appendix for the soils map and scale factor exhibits. B. EXISTING CONDITIONS The Laurelhurst Property is 30.1 acres and currently drains to the east, three areas totaling 4.92 acres (2.26 + 2.10 + 0.56) are also tributary along with 1.10 acres of roadway along Duvall Ave NE. By using the topographic survey for the project the measured exiting impervious, forested and pasture areas were measured. Below is a summary of the areas, see Figure 3a for a detailed tabulation of the measured areas. Note that the 5.50 area on the east side of Phase II is not included in the predeveloped timeseries because it flows to the east.

DEVELOPEDCONDnGONS The developed site will consist of 136 lots, 69 lots in Phase I and 67 lots in Phase TI. The impervious area for the plat was detennined by measuring the right of way area which is 100% impervious and adding 4,000 SF per lot. Phase I: measured r/w = 3.16 Ac Impervious area = [69 x 4000]/43560 + 3.16 = 9.50 Ac Phase II: Measured r/w = 2.91 Ac Impervious Area = [67 x 4000]/43560 + 2.91 = 8.55 Ac The remainder of the area was assumed to be lawn. Below is a summary of the areas, see Figure 3a for a detailed tabulation of the measured areas. Note that the 5.50 area on the east side of Phase II is included in the developed timeseries. This information was used to produce the Predeveloped RunoffTimeseries (DEV) in the KCRTS program. The entire east basin (5.50 ac) will be directed to the west basin in the developed state. The difference between the predeveloped area (30.82) and the developed area (36.32 ) is the 5.50 acres. I I I I I I I I I I I I I I I I I I I 9/2212004 AREA TABULATIONS .

DETENTION ROUTING CALCULATIONS The City of Renton requires that the Level 2 Flow Control standard apply to this project. This standard requires that the proposed pond outfall match 2-year predeveloped release rate and the not exceed the other predeveloped design storm events up to the 10 year event. The pond is also required not to exceed frequency and duration for Y:z the 2-year up to the 50-year storm events. Using the appropriate release rates the developed timeseries was modeled in a pond with 2:1 sides slopes, 12-feet of water depth and a pond bottom of21,762 sf (234 x 93). A two orifice control structure was design to meet the release rates . and frequency duration standards. See the Appendix of this report for the detailed KCRTS calculations. The resultant pond volume required was 355,215 c£ The volume provided on the plan is 402,785 cf. Therefore the pond, as shown on the plans is adequate to provide the required volume and maintain the frequency and duration of storm runoff from the project.

WATERQUALI~VOLUME The water quality volume (dead storage) was determined using the procedure outlined in the King County Surface Water Design Manual Page 6-68. In this procedure a volume is detennined using the areas of Impervious, Forest and Grass land-covers in the developed basin. The volume (Vr) is then mUltiplied by a factor (3 in this case) to determine the total minimum volume required. The land-covers, as determined in the pond sizing calculations, are repeated in the following table: ::ptVELorEDCoNDITIONS'; , ~te~)ijblft.¢;S_P.tm .. ry,6f:Ait~3~l:, ' Ground Cover Till-forest Till-grass Impervious Area , ...

Conveyance System Analysis and Design The storm drainage conveyance system was designed in accordance the 1998 KCSWDM to provide for all the conveyed runoff for the 100-year event to be totally contained with in the catch basins. The King County Backwater Analysis program, version 4.22 was used to model the system. The total100-year maximum storm rate of 12.39 CFS from the 28.1 acre site was proportioned to the individual sub-basins based on area. For example a catchment 5.5 acres in size would have a 100-year flow of: 5.5/28.1 *12.39 = 2.4 cfs Q ratios were computed for each catchment based on the area entering flow at the junction divided by the total area upstream of the node. A detailed list of the q ratios, a schematic of each drainage conveyance model, and the results follow.

Suite 202 Bellevue, Washington 98004 Attention: Subject: Reference: Dear Mr. Ollestad: Mr. Paul Ollestad Storm Detention Pond Liner Laurelhurst, Tract U Renton, Washington Earth Consultants, Inc. Geotechnical Engineering Study E-10988, dated January 28. 2004 At your request, Earth Consultants, Inc. (ECI) is pleased to provide this letter presenting our I recommendations for the pond liner in the proposed Tract U storm detention pond. We previously . 'prepared the referenced geotechnical engineering study for this project. In preparing this letter, we reviewed the proposed storm drainage plans and our previous work. . I The approximately 30-acre, irregular shaped site, located at 138th Avenue Southeast and Southeast 132~ Street in Renton, Washington. is to be developed with one hundred thirty-nine I (139) single-family residence lots. Stormwater runoff from the proposed development is to be diverted to a large stormwater control pond to be located in Tract U near the southwest corner of the site. The stormwater control pond is to contain two cells, each with a bottom elevation of I approximately 364 feet. Excavations of twelve (12) to twenty-four (24) feet below existing grade are expected to reach this proposed grade. The proposed stormwater pond will be bordered immediately to the west by an approximately 20 to 30 foot high southwest-facing slope that I . descends southwest to a creek at gradients of around 65 to 100 percent. A total of fifteen (15) test pits were excavated at the subject site on December 31, 2003, to I determine subsurface soil conditions. At our test pit locations, we generally encountered six (6) to twelve (12) inches of topSOil and duff. Under1ying the topsoil and duff layers, we encountered loose to medium dense silty sand with gravel overlying weathered to unweathered silty sand I with grav~11 which we classified as glacial till. At five of our test pit locations, we encountered one and one-half to two and one-half feet of gravel with varying amounts of silt and sand. This gravel layer was observed between the surficial layer of silty sand the underlying glacial till. I Four of the five test pit locations containing this gravel lens were located north of the proposed pond, at distances ranging from forty (40) feet to three hundred (300) feet north of the north ~dge of the pond. As such. we anticipate gravel may be encountered in the proposed pond I excavation. I 1805 136th Place N.E ..

The soil liner should be at least eighteen (18) inches thick and meet the following gradational requirements: Gradational Requirements Sieve Size Percent Passing 6-inch 90 4-inch 100 No.4 70-100 No. 200 20-100 The pond liner should consist of a glacial till derived fill. Based on laboratory testing of test pit samples, there are soils within the site that meet these gradational requirements . . ~ The liner materials should be placed in six-inch thick loose lifts and each lift should be compacted to 95 percent of maximum dry density per ASTM 0-1557, Modified Proctor. A representative from Eel should be on-site during the compaction operation and liner placement to observe the materials. soils that are encountered, sample and test the liner, and test the relative compaction of the soil liner. We trust this infonnation meets your needs. If you have any questions, please call. Respectfully submitted. Eric L.
