' ,. •''' JayMarc Development July 3, 2007 _.,; .... ' .-. ES-0873.01 Page7 ·· With respect to the proposed detention vault construction, competent native soils suitable for support of the vault foundations are anticipated to be exposed at the vault subgrade elevation. For design, the following geotechnical parameters should be used: • Allowable Soil Bearing Capacity • Active Earth Pressure (Yielding Wall) • At-Rest Earth Pressure (Restrained Wall) • Soil Unit Weight • Active Earth Pressure Coefficient {Ka) • At-Rest Earth Pressure Coefficient {Ko) 5,000 psf 35pd SO pd 125 pcf 0.28 0.40 Traffic surcharge loading above the vault should be included in the design pressures, as · appropriate. Drainage around the vault walls or a means to relieve the buildup of hydrostatic pressures should be provided. In our opinion, the use of sheet drain around the vault walls can be considered in lieu of free draining backfill. The geotechnical engineer should review the vault design, and provide supplemental recommendations, as appropriate. The presence of perched groundwater seepage should be expected in the detention vault excavations. For purposes of the vault design, the seasonal high groundwater seepage level should be assumed at a depth of eight feet. Rockeries and Modular Block Walls In our opinion, the use of rockeries or modular block walls at this site is feasible from a geotechnical standpoint. Rockeries or modular block walls over four feet in height will require an engineered design. ESNW can provide engineered rockery and modular block wall designs, upon request. The geotechnical engineer should review the final wall alignments and wall heights with respect to the proposed site grading. Utility Trench Backfill In our opinion, the soils observed at the test sites are generally suitable for support of utilities. Organic or highly compressible soils encountered in the trench excavations should not be used . for supporting utilities. In general, the native soils anticipated to be exposed during grading should be suitable for use as structural backfill in the utility trench excavations, provided the soil is at or near the optimum moisture content at the time of placement and compaction and fines contents are within acceptable limits to maintain stability. Moisture conditioning of the soils may be necessary at soine locations prior to use as structural fill. Utility trench backfill should be placed and compacted to the specifications of structural fill provided in this report, or to the applicable specifications of King County, as appropriate.

JayMarc Development July 3, 2007 · · · · ., ,, ..... ; .. ,.,,'' . . .,. ~ .J/ • 'l\ ., : ES-0873.01 Page7 ·• ·. · With respect to the proposed detention vault construction, competent native soils suitable for support of the vault foundations are anticipated to be exposed at the vault subgrade elevation. For design, the foUowing geotechnical parameters should be used: • Allowable Soil Bearing Capacity • Active Earth Pressure (Yielding Wall) • At-Rest Earth Pressure (Restrained Wall) • Soil Unit Weight • Active Earth Pressure Coefficient (Ka) • At-Rest Earth Pressure Coefficient (Ko) 5,000 psf 35 pcf 50 pcf 125 pcf 0.28 0.40 Traffic surcharge loading above the vault should be included in the design pressures, as appropriate. Drainage around the vault walls or a means to relieve the buildup of hydrostatic pressures should be provided. In our opinion, the use of sheet drain around the vault walls can be considered in lieu of free draining backfill. The geotechnical engineer should review the vault design, and provide supplemental recommendations, as appropriate. The presence of perched groundwater seepage should be expected in the detention vault excavations. For purposes of the vault design, the seasonal high groundwater seepage level should be assumed at a depth of eight feet. Rockeries and Modular Block Walls In our opinion, the use of rockeries or modular block walls at this site is feasible from a geotechnical standpoint. Rockeries or modular block walls over four feet in height will require an engineered design. ESNW can provide engineered rockery and modular block wall designs, upon request. The geotechnical engineer should review the final wall alignments and wall heights with respect to the proposed site grading. Utility Trench Backfill In our opinion, the soils observed at the test sites are generally suitable for support of utilities. Organic or highly compressible soils encountered in the trench excavations should not be used for supporting utilities. In general, the native soils anticipated to be exposed during grading should be suitable for use as structural backfill in the utility trench excavations, provided the soil is at or near the optimum moisture content at the time of placement and compaction and fines contents are within acceptable limits to maintain stability. Moisture conditioning of the soils may be necessary at soine locations prior to use as structural fill. Utility trench backfill should be placed and. compacted to the specifications of structural fill provided in this report, or to the applicable specifications of King County, as appropriate.

Box 2566 Renton, WA 98056 RE: Permit Fee Estimate Project: Panther Ridge File Number: L07SR037 Dear Applicant: Thank you for submitting the engineering plans for site development of the Panther Ridge subdivision. 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 May 25, 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 several standard design documents for evaluating the plat requirements were not included in the submittal. The design items identified during the screening process 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 upol) the fee estimate disclaimers. To provide an efficient process for review of the engineering plans, it is recommended that the missing design information be addressed in your next submittal with the required fee payment. Marc Rousso June 11, 2007 Page 2 Once the attached fee estimate form is signed and submitted to our Department with the estimated fee payment, 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 L07SR037 and the signed fee estimate form shall be delivered mailed 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.

The applicant is required to submit a signed copy of this form with the application and fee payment acknowledging that the applicant has read the disclaimers stated below. Disclaimer 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 DDES 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 or identified later in the process, a new estimate may be required. Applicants will be responsible for any additional hours identified in a new estimate because of: 1) Changes in the project and unknown or undisclosed site issues. 2) Incomplete information or errors in applicant submittal. 3) County code fee changes. 4) Fees for structural review. 5) Fees for variance applications. 6) One major and one minor set of redline comments. 7) Construction Bond amount that exceeds $500,000. 8) Plat Condition 16 -Tree retention plan not submitted. 9) Grading plan not provided. 10) Structural plans for storm vault not provided. 11) TIR not complete and poorly organized. 12) Pollution Control plan not provided per drainage manual pages 2-16 and 2-28. 13) Cul-de-sac length exceeds 600' limit in KCRS 2.08.

The proposed plat will create 22 residential lots with a drainage/recreation tract and 2 joint driveway tracts. The property has two existing houses that will be removed. There are several additional ancillary buildings on the site, all of which will be removed. The existing vegetation is generally lawn and short field grass with several fir, cedar and fruit trees located near the west side (front) of the lots. The tree density would be considered as very light. The pasture grass has small, sporadic patches of brambles and native wild shrubs. The existing topography is sloping down from the east to the west. The lowest area of the site is along the west property line. near the northwest . corner. The highest area of the site is the east property line. The average slope across the property is approximately 3.5%. This slope is fairly consistent across the site. The steepest slope is a very low bank in the northwest corner. It is a 5' high rise of approx. 20%. There are no wetland or slope sensitive areas on this site. This plat proposes to construct several improvements including a central public road that will include a cul-de-sac turn-around bulb. All of the proposed lots will have a driveway access from this new interior road. There are 4 lots along the south property line. These lots will use two joint use driveway tracts for access. The plat will include a drainage facility that will be located in the northwest comer and will utilize a subsurface concrete vault and wetvault. It will be situated in a tract that will also be used as a recreation tract. The proposed plat will gain access from 102nd Ave. SE. along the west property line. This is a public road that is entirely within the City of Renton. The city limit line is the east ROW line. This road is currently improved with curb, gutter & sidewalk. The proposed cul- de-sac will be connected to this City street. There is a new subdivision across 102nd Ave. SE that is currently under construction. This subdivision is within the City of Renton. The site is within the Panther Creek sub-basin of the Lower Green River Drainage basin. There are no drainage improvements on the site. There is a drainage system within 102nd Ave. SE. This drainage system includes several catch basins and interconnecting piping. This drainage system continues along S. 47th St., along the north side of the plat and runs to the west. The drainage from the site will discharge into this public drainage system. Panther Creek is • located north of the site, approx. 170' north of the northeast property corner.· The creek flows to the northwest. The existing drainage system within S. 47th St. discharges into a swale that runs directly into the creek. On-site surface water runoff flows along the lawn and pasture grass towards the west and onto 102nd Ave. SE. The proposed plat will include drainage detention and water quality control measures. The detention facility will be located in the northwest corner. The detention facility will include a combination detention vault and a wetvault. The detention vault will be designed for a conservation flow drainage detention standard. The wetvault will be designed to meet the basic water quality requirements. The vault will discharge into a pipe and catch basin northwest of the property, within S. 47th St. A new drainage pipe will then be installed within the existing street to connect to the existing type 2 catch basin. The drainage system for this project will be designed using the 2005 King County Drainage Manual. Each house and yard will be equipped with a perforated downspout trench with an overflow pipe connected to the street drainage system and to the detention facility. The new roads will be equipped with catch basins and rolled curb gutters that collect the runoff. Solid pipes will carry the runoff from the collection devices to the pond at the northwest corner of the site. The site soils are classified as Alderwood sandy, gravely loam throughout the property. These soil classifications were taken from the USDA Soil Conservation Service soils map for King County. As such, infiltration is not an option for the drainage disposal from this site. These soils typically do not have the permeability necessary to meet the County drainage code requirements for infiltration systems. The necessary depth to groundwater for infiltration is also doubtful in this general vicinity. · The site is within the Soos Creek Community Plan. .. • : I I = • 11 MN•Olla ..... -.i1--.. 1 · I '1 : I I ,,~ !I § i"' • & I :q I r.

Safe passag~ of fire and other emergef!CY_ vehic_Ies is constrained by on-street parking when there C j5 iriadequate pavement width tO accommodate both parked Vehic)es and emergency Vehic)es. :· :· .:: : Kiiig County Fire District No: 40 has shown by substantial evidence that if a street width is less ,; :· . than 28 feet; parking permitted on' eiiher side of the ·street interferes with the rapid passage of fire :'. 'and othercinergcncy vehicles: Similarly, if pavcincnt width is less than 36 feet, and vehicles arc -parked on both sides ofthe'street, fire and eiiicrgei;cfvehicle access is substantially constrained. Such constraint occasionally requires that vehicles be moved to enable emergency vehicles to pass. This causes ari increase in the response time fo emergency incidents.'' '. , Thi: Applicant for this subdivision has agreed to provide a minimum 28 foot pavement width for · ·,: Southeast 184th Place;·with sidewalk on· one side of the roadway. This would enable parking to .: , be permitted ori one side ·of Southeast· 184th Place without constraining emergency vehicle . access. It is the responsibility of the King County Department of Transportation to provide signing that would prohibit parking on one side of the street, to assure unconstrained access of fire and other emergency vehicles. S. The Applicant has considered various layouts for the proposed subdivision, and has considered the impact of the subdivision design on adjacent properties. No alternative design appears feasible io accomplish a 22 lot develcipment.' 22 dwelling units is the minimum number required ' on this property to meet the requirements ·ot the R-8 zone classification;•··.: ' . .

' FIELD INSPECTION A visual reconnaissance of the site and the offsite drainage system was performed in January of 2006. The weather was wet and had been raining consistently for several weeks. UPSTREAM OFFSITE DRAINAGE CONTRIBUTION There is no up-gradient property from which runoff would flow onto this site. The east property line is approx. 200' west of Panther Creek. Very near the east property line, the grade begins to slope to the east, away from the plat. and towards the creek. The creek has formed a deep ravine. The top of the ravine slope is approx. 50' east of the property. The south property line is the plat of Windsor Heights. This is a dense residential plat similar to this proposed plat. The slope of the ground is similar to the subject property and there are only rear yards that adjoin the subject property. The north property line is a large parcel owned by the City of Renton and is part of the Panther Creek drainage corridor. The ground slopes to the north and away from the plat. The west property line is 102nd Ave. SE and has a drainage system that controls the runoff. It is also the low side of the property. Based on the above surrounding property descriptions, there is no off-site drainage that flows onto this site . . DOWNSTREAM DRAINAGE ANALYSIS There are two drainage basins within the subject plat. The site generally slopes to the west, except for the eastern end. There is a gentle ridge that runs northwest/southeast and divides the property into 2 drainage sub- basins. The western sub-basin is the larger, with an area of 2.91 acres. The eastern sub-basin is 0.53 acres, or 15.4% of the site area. There is an existing large house on the site. It is centered on the ridge. The long gravel driveway is in the western sub-basin. EASTERN SUB-BASIN: The existing runoff from the eastern sub-basin sheet flows to the northeast property corner. This northeast corner is the top of the slope/ravine down to Panther Creek. The Creek bottom is approx. 200' northeast of the property comer. The slope drops approx. 100' in elevation. This point of Panther Creek is approx. 1200' upstream of the confluence of the ditch/ swole that conies the western sub-basin flow into Panther Creek. The property north of the subject plot. which contains Panther Creek and the ravine slopes, is owned by the City of Renton as open space. There ore no improvements within this downstream drainage course. WESTERN SUB-BASIN: There ore no drainage improvements on the property. The existing site runoff sheet flows to the west and flows onto 102nd Ave. SE. This street hos a constructed drainage system that collects the .runoff within the street gutters and catch basins. 1 . The drainage from the detention vault will be restricted to a level 2 flow control standard. The outlet from the vault will be piped to on existing catch basin located 65' northwest of the vault. This is a type 2 CB and is situated within the pavement, north of the centerline, of S. 47th St. 2. This CB hos a 12" outlet pipe that runs to the west for 100' and enters a second type 2 CB. The pipe travels under the north side of the street pavement within S. 47th St. 3. The second type 2 CB is approx. 1 O' deep and hos on 18" outlet to the northwest with an open outlet to a natural drainage channel that flows to the northwest. This outlet pipe is approx. 40' long and is situated at the bottom of the bank that was created by the constructed rood fill for S. 47 1h St. 4. The natural drainage channel is situated within a large tract owned by the City of Renton that also includes Panther Creek. The channel is wide and hos a vegetated covering of small alder trees, brush and posture gross. Approx. 500' north of S. 47th St.. the channel runs into an old grovel rood that goes to an old gravel pit. The channel flows along the east side of the road in a shallow channel created by the road. The channel then turns to the northeast and flows down a steep slope and into Panther Creek. This confluence is approx. 800' north of S. 47th St. and 1000' downstream from the subject site. 5. Panther Creek flows to the northwest within a well-defined, deep ravine that is heavily treed. There are steep slopes on both sides of the ravine. Approx. 800' downstream from the confluence with the smaller channel, Panther Creek crosses under Petrovitsky Road. The type of culvert was not determined as it was not accessible for inspection. This is approx. 1800' downstream from the subject plat. 6. Panther Creek continues to flow to the northeast within the deep ravine. The ravine crosses under Talbot Road S .• north of the Valley Medical Center. The Creek continues past Talbot Road and enters a broader drainage channel that flows into the large wetland area the is along the east side of SR 167. SUMMARY The downstream system has only a few constructed components just past the site. These type 2 catch basins and piping appear to be deep and sufficient to accommodate all of the existing and proposed flows. The natural drainage channel and Panther Creek are large conveyance mechanisms. The developed flows from the proposed plat will introduce a fraction of the existing flows within the stream. The proposed plat should not have a significant effect on the downstream drainage system. J 1 j ., ., ] ~ -I ·. v.t.ut r ouTt.Er w/ now j S--e,y-r 1ced• RESTRICTOR TtE .! ,-· I ) \.

County Water and Land Resource Division. The list of the complaints for the general area is attached. These are the documented complaints for the area that is north and northwest of the subject plat and may not be within the downstream drainage system. I have reviewed the attached downstream drainage complaints list and there is only 1 of the complaints that is within the downstream drainage area. This complaint is highlighted on the attached list that was obtained from the County. The complaint is: • 2002-0089: @ 9840 S. Carr Rd. (Petrovitsky Rd.), The complaint is a request for a re-measurement of existing impervious surface for a prior use when related to a new proposed use of the property. Panther Creek appears to run through this site. The complaint is not related to the stream or any drainage conveyance issue. The County drainage complaints from the IMAP program highlighted 2 more lots that were on the north side of Petrovitsky Rd. as site with drainage complaints. These lots were: · 851 S. Carr Rd. 17712 98'hAve. S. However. the County list of complaints in this area did not include these sites. There is no information available.

This menu is outlined in chapter 5 of the Drainage Manual. Certain items within the menu. if used on the lots. will allow impervious surface credits that can be applied to the design of the drainage detention system. For this project. no lot BMP lot credits are anticipated. The BMP menu is for the small lot list. since all of the lots are less than 22,000 SF. The list of small lot BMP's are: 1. Limited Infiltration: This would not be allowed on these lots because the soils are a sandy silt with limited infiltration capacity, there is a layer of Vashon TIii located approx. 2.5' below grade. Also, the lots are too small lo provide the necessary setbacks for infiltration trenches lo property lines._.· • . . 2. Basic Dispersion: ;This requires 25' min. of vegetated flow path. This is hot available on these lots. ' 3. Rain Garden: This may be possible on some of !he larger lots in this site. However, most of the lots will not have enough area in the rear yards to provide the setbacks and pool area for a rain garden. 4. Permeable Pavement: This can be provided by !he house builder at !he time of building permit. II would only apply to the;driveway within the lot. We would not want lh1sto ~ a requirement of the lots on !his plat, so we are nolspecifying or using credits for this BMP. · 1 ':-. . '-"·· 5. Rainwater Harvesting: This require{btype of collection and storage syst~rn that can only oe· constructed as part of the house'. construction.

This is reflected in the developed condition peak flow calculations. A restrictive note will be placed on the final plat plan. All of the lots will utilize perforated pipe drainage connections. This is required for the use of this credit. 8. Native Growth Retention Credit: These Jots are too small to provide a native growth retention area. Some of the above options, such as a rain garden, can be proposed at the time of the building permit. when the actual house building plans will provide a much more detailed analysis of the BMP options. A perforated pipe connection will be used for all of the Jots for connecting the lot drainage to the public drainage system in the road. This will be detailed on the engineering plans. . . .•· .. , / ·~;_, ·:: Sf \}~f~~\};; :.:~w}f 1~Jt'.rt}/::i1f?:: · -, . . .... , ;:··- · · . ::'.t~· .t· · · ,, .·· CONVEYANCE ·svsreM \::.:. ···~-;\.1)··· .. ·.~-t~?f?\ · .. ~-i·'··· '"::·: ~:~. -·.": ~·-· -·~?·~.t :· · · ~·. · ·.-• The piping ~ilf be sized to accommodate the 100 year developed flows · as identified in the previous section of the report.

Except as modified herein, the facts set forth in the King County Land Use Services Division's preliminary report to the King County Hearing Examiner for the February 13, 2007, public hearing are found to be correct and are incorporated herein by this reference. The LUSD staff recommends approval of the application, subject to conditions. 3. The proposed subdivision abuts 102nd Avenue Southeast along the west property line. 102nd Avenue Southeast is entirely within the jurisdiction of the City of Renton. All improvements to 102nd Avenue Southeast will be subject to review and approval by the City of Renton. The City of Renton has requested that internal streets within the subdivision also be improved to City of Renton standards. There is no interlocal agreement between the City of Renton and King County to require development within King County to meet City of Renton standards, notwithstanding that the proposed subdivision is within the City ofRenton's potential annexation area. King County road standards are applicable to the internal streets within the proposed subdivision. 4. Safe passage of fire and other emergency vehicles is constrained by on-street parking when there is inadequate pavement width to accommodate both parked vehicles and emergency vehicles. King County Fire District No. 40 has shown by substantial evidence that if a street width is less than 28 feet, parking permitted on either side of the street interferes with the rapid passage of fire and other emergency vehicles. Similarly, if pavement width is less than 36 feet, and vehicles are parked on both sides of the street, fire and emergency vehicle access is substantially constrained. Such constraint occasionally requires that vehicles be moved to enable emergency vehicles to pass. This causes an increase in the response time to emergency incidents. The Applicant for this subdivision has agreed to provide a minimum 28 foot pavement width for Southeast 184th Place, with sidewalk on one side of the roadway. This would enable parking to be permitted on one side of Southeast 184th Place without constraining emergency vehicle access. It is the responsibility of the King County Department of Transportation to provide signing that would prohibit parking on one side of the street, to assure unconstrained access of fire and other emergency vehicles. 5. The Applicant has considered various layouts for the proposed subdivision, and has considered the impact of the subdivision design on adjacent properties. No alternative design appears feasible to accomplish a 22 lot development. 22 dwelling units is the minimum number required on this property to meet the requirements of the R-8 zone classification. CONCLUSIONS: 1. If approved subject to the conditions recommended below, the proposed subdivision will comply with the goals and objectives of the King County Comprehensive Plan, subdivision and zoning codes, and other official land use controls and policies of King County. 2. If approved subject to the conditions recommended below, this proposed subdivision will make appropriate provision· for the public health, safety and general welfare, and for open spaces, drainage ways, streets, other public ways, transit stops, potable water supply, sanitary waste, • • L06P0008 -Panther Ridge Page4of10 parks and recreation, playgrounds, schools and school grounds and safe walking conditions for students who only walk to school; and it will serve the public use and interest. 3. The conditions for final plat approval recommended below are in the public interest and are reasonable and proportionate requirements necessary to mitigate the impacts of the development upon the environment. 4. The dedications ofland or easements within and adjacent to the proposed plat, as required for final plat approval or as shown on the proposed preliminary plat submitted by the Applicant on February 23, 2006, are reasonable and necessary as a direct result of the development of this proposed plat, and are proportionate to the impacts of the development. 5. Improvements of the plat roads and access tracts within King County are subject to the King County Road Standards. There is no authority for King County to require the Applicant to meet City of Renton standards for construction within King County. Improvements to I 02nd Avenue Southeast are subject to the jurisdiction of the City of Renton. 6. Safe fire and emergency vehicle access within this development may require that parking be restricted to one side of Southeast 184th Place if the pavement width of that street is between 28 feet and 36 feet. If the pavement width is less than 28 feet, parking may be restricted from both sides of Southeast 184th Place to assure safe fire and emergency vehicle access along the full length of the street. The King County Department of Transportation should review the approved construction of Southeast 184th Place and establish parking restrictions consistent with the need to assure unimpeded fire and emergency vehicle access to all lots within the plat.- 7. The lot layout of the proposed subdivision is consistent with the minimum density requirement and the maximum density permitted for property in the R-8 zone classification. The Jot layout is . reasonable and consistent with the public interest in achieving urban densities within the urban area of King County. DECISION: The proposed preliminary plat of Panther Ridge, as revised and received on February 23, 2006, is approved, subject to the following conditions of final plat approval: I. Compliance with all platting provisions of Title 19A of the King County Code. 2. All persons having an ownership interest in the subject property shall sign on the face of the final plat a dedication that includes the language set forth in King County Council Motion No. 5952. 3. The plat shall comply with the base density and minimum density requirements of the R-8 zone classification. All lots shall meet the minimum dimensional requirements of the R-8 zone classification or shall be shown on the face of the approved preliminary plat, whichever is larger, except that minor revisions to the plat which do not result in substantial changes may be approved at the discretion of the Department of Development and Environment Services. l • • L06P0008 -Panther Ridge Page 5 of 10 Any/all plat boundary discrepancy shall be resolved to the satisfaction of ODES prior to the submittal of the final plat documents. As used in this condition, "discrepancy" is a boundary hiatus, an overlapping boundary or a physical appurtenance which indicates an encroachment, lines of possession or a conflict of title. 4. All construction and upgrading of public and private roads within the plat shall be done in accordance with the King County Road Standards established and adopted by Ordinance No. 11187, as amended (1993 KCRS). 5. The applicant must obtain the approval of the King County Fire Protection Engineer for the adequacy of the fire hydrant, water main, and fire flow standards of Chapter 17 .08 of the King County Code. Final plat approval shall require compliance with the conditions of the fire systems review approval date March 29, 2006 (exhibit no. 16). 6. Final plat approval shall require full compliance with the drainage provisions set forth in King County Code 9.04. Compliance may result in reducing the number and/or location oflots as shown on the preliminary approved plat. Preliminary review has identified the following conditions of approval which represent portions of the drainage requirements. All other applicable requirements in K.C.C. 9.04 and the Surface Water Design Manual (SWDM) must also be satisfied during engineering and final review. a. Drainage plans and analysis shall comply with the 2005 King County Surface Water Design Manual and applicable updates adopted by King County.

Jaeger Engineering 9419 South 204th Place Kent, WA 98031 RE: Panther Ridge Subdivision 2005 KCSWDM Adjustment Reguest (File No. L06V0080) Dear Applicant and Engineer: The Land Use Services Division, Engineering Review Section, has completed review of the adjustment request for the Panther Ridge subdivision. You are requesting approval for an adjustment from the 2005 King County Surface Water Design Manual (KCSWDM) Core Requirement No. I, Section 1.2.1, Discharge at the Natural Location. Our review of the information and a site visit provides the following findings: I. The proposed Panther Ridge subdivision is located at 18404 I 02nd Avenue SE. The 22 lot, 3.44 acre, proposed Panther Ridge subdivision is filed under Land Use Services Division (LUSD) file number L06P0008. 2. The Panther Ridge subdivision is located in the Panther Creek subbasin of the Black River basin. The site is subject to Che Conservation flow control and Basic water quality requirements of the 2005 KCSWDM. 3. The large, notched rectangular site is oriented in an east-west direction. The eastern end of the site contains a northwest to southeast oriented low ridge separating drainage runoff into a small, eastern sub basin and a larger, western subbasin. The majority of the site slopes gently to the west with runoff intercepted by the storm drainage conveyance system of I 02nd A venue SE. This system flows north and then turns west on South 4 7th Street and enters a drainage swale as a tributary to Panther Creek. The smaller, eastern sub basin sheetflows to the northeast and over steep slopes directly to Panther Creek. Flows from both sub basins of the site recombine in Panther Creek. There is no upstream flow tributary to the site. 4. The proposal is to collect most runoff from the project site and direct it to a single detention and water quality facility located in the northwest comer of the site. The allowed release would then follow the naturai discharge location of the western subbasin. There would be a slight reduction of flows directly to Panther Creek at the eastern end of the site. Frontage improvements already exist on the site. It is unclear Panther Ridge/L06V0080 October 19, 2006 Page 2 of3 if the wetpond has the required 3: I length to width ratio without structural assistance in the conceptual drainage plan. 5. No decorative ponds or shallow wells have been identified that would be affected by the proposed diversion. 6. The Level One Drainage Analysis identified no restrictions or conveyance problems associated with the proposed discharge location. Drainage complaints in the downstream path were either not related to conveyance or not obtainable. 7. A consolidation of facilities for the proposed subdivision will be more economical in long term maintenance. Based on these findings, we hereby approve this adjustment to allow the diversion of runoff to a single combined facility draining to South 47th Street with the following conditions: I. The release rates for the detention facility will be based on all of 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 Conservation flow control standard in the 2005 KCSWDM. The design Technical Information Report shall state the factor of safety selected and the basis of that determination. 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, recreation space tract with easement or storm drainage tract dedicated to King County. 5. Additional storm drainage requirements identified by SEPA or the plat hearing review will apply to this project. The applicant retains all rights and privileges afforded in Section 1.4.

L06P0008 The requested adjustment is for a diversion of drainage flows within a 22 lot residential plat. The site is 3.44 acres. The property is approx. 600' long and 300' wide. The long dimension runs east/west. The site generally slopes to the west, except for the eastern end. There is a gentle ridge that runs northwest/southeast and divides the property into 2 drainage sub- basins. The western sub-basin is the larger, with an area of 2.91 acres. The eastern sub-basin is 0.53 acres, or 15.4% of the site area. There is an existing large house on the site. It is centered on the ridge. The long gravel driveway is in the western sub-basin. The existing runoff from the western sub-basin flows to the western property line, which is 102nd Ave. SE. This is an improved public road with curb, gutter & sidewalk. There is an existing drainage system with catch basins and piping within the road. The runoff from the western basin enters these catch basins and is pipe to the northwest. The piping runs in approx. 200' of pipe and then into a large swale/dilch that flows to the north for approx. 200' and into Panther Creek. The piping system is within S. 47th St. and the ditch is within a Tract owned by the City of Renton. The existing runoff from the eastern sub-basin flows to the northeast property corner. This northeast corner is the top of the slope/ravine down to Panther Creek. The Creek bottom is approx. 150' northeast of the property corner. This point of Panther Creek is approx. 1200' upstream of the confluence of the ditch swale that carries the western sub-basin flow. The property north of the subject plat is all owned by the City of Renton as open space. The diversion will take a small amount of developed flow from the eastern sub-basin and direct ii into the western sub-basin. This developed flow will be limited to the roof downspouts for lots 13, 14 and 15 and half of the cul- de-sac bulb. The yard flows from the 3 lots will continue to flow naturally across the lawns to the northeast. The diversion area will consist of approx. 12000 SF. The adjustment should be approved because both basins are tributary to Panther Creek. The downstream system of the diverted flow is a good piping and ditch system that is in a Tract owned by the City of Renton as open space.

Box 2566 Renton, WA 98056 •, . ... James J. Jaeger, P.E. Jaeger Engineering 9419 South 204 th Place Kent, WA 98031 RE: Panther Ridge Subdivision 2005 KCSWDM Adjustment Request (File No. L06V0080) Dear Applicant and Engineer: The Land Use Services Division, Engineering Review Section, has completed review of the adjustment request for the Panther Ridge subdivision. You are requesting approval for an adjustment from the 2005 King County Surface Water Design Manual (KCSWDM) Core Requirement No. I, Section 1.2.1, Discharge at the Natural Location. Our review of the information and a site visit provides the following findings: I. The proposed Panther Ridge subdivision is located at 18404 I 02nd Avenue SE. The 22 lot, 3.44 acre, proposed Panther Ridge subdivision is filed under Land Use Services Division (LUSD) file number L06P0008. 2. The Panther Ridge subdivision is located in the Panther Creek subbasin of the Black River basin. The site is subject to the Conservation flow control and Basic water quality requirements of the 2005 KCSWDM. 3. The large, notched rectangular site is oriented in an east-west direction. The eastern end of the site contains a northwest to southeast oriented low ridge separating drainage runoff into a small, eastern subbasin and a larger, western subbasin. The majority of the site slopes gently to the west with runoff intercepted by the storm drainage conveyance system of I 02nd A venue SE. This system flows north and then turns west on South 47th Street and enters a drainage swale as a'tributary to Panther Creek. The smaller, eastern sub basin sheetflows to the northeast and over steep slopes directly to Panther Creek. Flows from both subbasins of the site recombine in Panther Creek. There is no upstream flow tributary to the site. 4. The proposal is to collect most runoff from the project site and direct it to a single detention and water quality facility located in the northwest comer of the site. The allowed release would then follow the natural discharge location of the western subbasin. There would be a slight reduction of flows directly to Panther Creek at the eastern end of the site. Frontage improvements already exist on the site. It is unclear Panther Ridge/L06V008, October 19, 2006 Page 2 of3 • if the wetpond has the required 3: I length to width ratio without structural assistance in the conceptual drainage plan. 5. No decorative ponds or shallow wells have been identified that would be affected by the proposed diversion. 6. The Level One Drainage Analysis identified no restrictions or conveyance problems associated with the proposed discharge location. Drainage complaints in the downstream path were either not related to conveyance or not obtainable. 7. A consolidation of facilities for the proposed subdivision will be more economical in long term maintenance. Based on these findings, we hereby approve this adjustment to allow the diversion of runoff to a single combined facility draining to South 47th Street with the following conditions: 1. The release rates for the detention facility will be based on all of 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 Conservation flow control standard in the 2005 KCSWDM. The design Technical Information Report shall state the factor of safety selected and the basis of that determination. 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, recreation space tract with easement or storm drainage tract dedicated to King County. 5. Additional storm drainage requirements identified by SEP A or the plat hearing review will apply to this project. The applicant retains all rights and privileges afforded in Section 1.4. · Panther Ridge/L06V008, October 19, 2006 Page 3 of3 • If you have any further questions regarding this KCSWDM adjustment or the design requirements, please contact Mark Bergam at (206) 296-7270.

Serv. Div., Site Engineering & Planning SWM ADJUSTMENT REQUEST PANTHER RIDGE PRELIMINARY PLAT KING COUNTY FILE NO. L06P0008 The requested adjustment is for a diversion of drainage flows within a 22 lot residential plat. The site is 3.44 acres. The property is approx. 600' long and 300' wide. The long dimension runs east/west. The site generally slopes to the west. except for the eastern end. There is a gentle ridge that runs northwest/southeast and divides the property into 2 drainage sub- basins. The western sub-basin is the larger, with an area of 2.91 acres. The eastern sub-basin is 0.53 acres, or 15.4% of the site area. There is an existing large house on the site. It is centered on the ridge. The long gravel driveway is in the western sub-basin. The existing runoff from the western sub-basin flows to the western property line, which is 102nd Ave. SE. This is an improved public road with curb, gutter & sidewalk. There is an existing drainage system with catch basins and piping within the road. The runoff from the western basin enters these catch basins and is pipe to the northwest. The piping runs in approx. 200' of pipe and then into a large swale/ditch that flows to the north for approx. 200' and into Panther Creek. The piping system is within S. 47th St. and the ditch is within a Tract owned by the City of Renton. The existing runoff from the eastern sub-basin flows to the northeast property corner. This northeast corner is the top of the slope/ravine down to PantherCreek. The Creek bottom is approx. 150' northeast of the property corner. This point of Panther Creek is approx. 1200' upstream of the confluence of the ditch swale that carries the western sub-basin flow. The property north of the subject plat is all owned by the City of Renton as open space. The diversion will take a small amount of developed flow from the eastern sub-basin and direct it into the western sub-basin. This developed flow will be limited to the roof downspouts for lots 13, 14 and 15 and half of the cul- de-sac bulb. The yard flows from the 3 lots will continue to flow naturally across the lawns to the northeast. The diversion area will consist of approx. 12000 SF. The adjustment should be approved because both basins are tributary to Panther Creek. The downstream system of the diverted flow is a good piping and ditch system that is in a Tract owned by the City of Renton as open space. The property that the diverted flow is removed from is also an open space Tract owned by the City of Renton. I . ---B"(rlcode ~.

Approval of this erosiofl and sedimentation control (ESC) plan does not constitute an approval of permanent rO<Jd or drainage design (e.g. size and location of road3, pipes, restrictars, channels, retention facilities, utilities, etc.). 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of thesiJ ESC facilities is the responsibility of the applicant/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing lirnits shall be maintained by the applicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown on this plan are the m1n1rnum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g. additiorial sump pumps, relocation of ditches and silt fences, etc.). 6. The ESC facilities shall be inspected daily by tile applicunt/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days durin9 the season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.). 8. Any area needing ESC rneasures, not requiring imrnediote attention, shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within 48 hours following a storm event. wet 10. At no time shall more than one (1) foot of sediment be allowed to accumulate within a catch basin. All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment-laden water Into the downstrearri system. 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12. Any permanent flow control facility used as a ten1porai-y settling basin shall be modified with the necessary erosion control measures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the ternporary facility must be graded so that the bottom and sides are at least three feet above the final grade of the perrnanent facility. SECTION 32, ·rowNSHIP 23 PERMANENT SEEDING NOTES 1. Seeding should be done immediately after final shaping if completed during the periods of April 1 through June 30 and September 1 through October 15 (if planted between July 1 and August 31 irrigati(Jrl may be required). Sites which cannot be seeded during this time period should be protected until the next seeding period with mulch. 2. Permanent vegetation may be In the form of grass seed mixtures, sod, or wetlands seed/tuber mixtures. Seed establishment shall include the use of supplemental materials, such as mulch. 3. Site preparation -install all required surface water control measures. 4. Seedbed preparation may include the following: a.) If infertile or coarse textured subsoil will be exposed during grading, stockpile topsoil and re-spread it over the finished slope and roll it to provide a firm seedbed. b.) If construction fills have left soil exposed with a loose, rough, or irregular surface, track walk up slope. c.) If cuts or construction equipment have left a tightly compacted surface, break with chisel plow or other suitable implement. Perform all cultural operations across or at right angles to the slopes (contoured). The seedbed should be firm with a fairly fine surface after roughening. 5. Fertilization -in general, 10-20-20 N-P-K fertilizer at a rate of 90 lbs./acre. Developrnents adjacent to water bodies and wetlands must use slow release low-phosphorus fertilizer (typical 3-1-2 N-P-K). 6. "Hydroseeding" applications with approved seed-mulch-fertilizer mixtures may also be used, as long as tackifier is included. 7. Seeding -apply appropriate mixture to the prepared seedbed at a rate of 120 lbs./acre. Cover the seed with topsoil or mulch no deeper than 1/2 inch . 8. Inspect seeded areas for failure and make necessary repairs and re-seedings immediately. a.) If vegetative cover is inadequate to prevent rill erosion, overseed and fertilize in accordance with soil test. b.) If a stand has less than 40°/o cover, reevaluate choice of plant materials and quantities of lirne and fertilizer. Re-establish the stand following seedbed preparation and seeding recommendations, ornitting lime and fertilizer in the absence of soil test results.

QUARRY SPALLS (OR HOG FUEL) SHALL BE ADDED IF THE PAD IS NO LONGER IN ACCORDANCE WITH THE SPECIFICATIONS. 2. IF THE ENTRANCE IS NOT PREVENTING SEDIMENT FROM BEING TRACKED ONTO PAVEMENT, THEN ALTERNATIVE MEASURES TO KEEP THE STREETS FREE OF SEDIMENT SHALL BE USED. THIS MAY INCLUDE STREET SWEEPING, AN INCREASE IN THE DIMENSIONS OF THE ENTRANCE, OR THE INSTALLATION OF A WHEEL WASH. IF WASHING IS USED, IT SHALL BE DONE ON AN AREA COVERED WITH CRUSHED ROCK, AND WASH WATER SHALL DRAIN TO A SEDIMENT TRAP OR POND.

BY: FILE No. ROAD SHEET 7 OF 8 ' ' ' ' . ' .. EROSION AN[) SEDIMENTAllON CONTROL NOTES 1. Approval of this erosion and sedimentation control (ESC) plan does not constitute an approval of permanent road or drainage design (e.g. size and location of roods, pipes, restrictors, channels, retention facilities, utilities, etc.). 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the applicant/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this pion shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing lirnits shall be maintained by the applicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown on this plan are the rn1n1rnurn requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g. additiorial sump pumps, relocation of ditches and silt fences, etc.). 6. The ESC facilities shall be inspected daily by the applicant/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days durin9 the season or seven days during the dry season shall be imrnediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.). 8. Any area needing ESC measures, not requiring imrnediote attention, shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within 48 hours following a storm event. wet 10. At no time shall more than one (1) foot basins and conveyance Jines shall be cleaned water into the downstream system. of sediment be prior to paving. allowed to accumulate within a catch basin. All catch The cleaning operation shall not flush sediment-laden 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12. Any permanent flow control facility used as a ternporary settling basin shall be modified with the necessary erosion control measures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the temporary facility must be graded so that the bottom and sides are at least three feet above the final grade of the permanent facility. A PORTION of the S. W. 1 / 4, SECTIOf\l 32, TOWNSHIP .23 N., RANGE 5 E., W.M. PERMANENT SEEDING NOTES 1. Seeding should be done immediately after final shaping if completed during the periods of April 1 through June 30 and September 1 through October 15 (if planted between July 1 and August 31 irrigation may be required). Siles which cannot be seeded during this time period should be protected until the next seeding period with mulch. 2. Permanent vegetation may be in the form of grass seed mixtures, sod, or wetlands seed/tuber mixtures. Seed establishment shall include the use of supplemental materials, such as mulch. 3. Site preparation -install all required surface water control measures. 4. Seedbed preparation may include the following: a.) If infertile or coarse textured subsoil will be exposed during grading, stockpile topsoil and re-spread it over the finished slope and roll it to provide a firm seedbed. b.) If construction fills have left soil exposed with a loose, rough, or irregular surface, track walk up slope. c.) If cuts or construction equipment have left a tightly compacted surface, break with chisel plow or other suitable implement. Perform all cultural operations across or at right angles to the slopes (contoured). Tt1e seedbed should be firm with a fairly fine surface after roughening. 5. Fertilization -in general, 10-20-20 N-P-K fertilizer at a rate of 90 lbs./acre. Developments adjacent to water bodies and wetlands must use slow release low-phosphorus fertilizer (typical 3-1-2 N-P-K). 6. "Hydroseeding" applications with approved seed-mulch-fertilizer mixtures may also be used, as long as tackifier is included. 7. Seeding -apply appropriate mixture to the prepared seedbed at a rate of 120 lbs./acre. Cover the seed with topsoil or mulch no deeper than 1/2 inch. 8. Inspect seeded areas for failure and make necessary repairs and re-seedings immediately. a.) If vegetative cover is inadequate to prevent rill erosion, overseed and fertilize in accordance with soil test. b.) If a stand has less than 40°/o cover, reevaluate choice of plant materials and quantities of lime and fertilizer. Re-establish the stand following seedbed preparation and seeding recommendations, omitting lime and fertilizer in the absence of soil test results. POLYETHYLENE CAP PROVIDE ADEQUATE STRAPPING STABILIZED CONSJRUCilON ENTRANCE MAINTENANCE STANDARDS 1. QUARRY SPALLS (OF! HOG FUEL) SHALL BE ADDED IF THE PAD IS NO LONGER IN ACCORDANCE WITH THE SPECIFICATIONS. 2. IF THE ENTRANCE IS NOT PREVENTING SEDIMENT FROM BEING TRACKED ONTO PAVEMENT, THEN ALTERNATIVE MEASURES TO KEEP THE STREETS FREE OF SEDIMENT SHALL BE USED. THIS MAY INCLUDE STREET SWEEPING, AN INCREASE IN THE DIMENSIONS OF THE ENTRANCE, OR THE INSTALLATION OF A WHEEL WASH. IF WASHING IS USED, IT SHALL BE DONE ON AN AREA COVERED WITH CRUSHED ROCK, AND WASH WATER SHALL DRAIN TO A SEDIMENT TRAP OR POND. 3. ANY SEDIMENT THAT IS TRACKED ONTO PAVEMENT SHALL BE REMOVED IMMEDIATELY BY SWEEPING. THE SEDIMENT COLLECTED BY SWEEPING SHALL BE REMOVED OR STABILIZED ON SITE. THE PAVEMENT SHALL NOT BE CLEANED BY WASHING DOWN THE STREET, EXCEPT WHEN SWEEPING IS INEFFECTIVE AND THERE IS A THREAT TO PUBLIC SAFETY. IF NECESSARY TO WASH THE STREETS, THE CONSTRUCTION OF A SMALL SUMP SHALL BE CONSIDERED. THE SEDIMENT WOULD THEN BE WASHED INTO THE SUMP. 4. ANY QUARRY SPALLS THAT ARE LOOSENED FROM THE PAD AND END UP ON THE ROADWAY SHALL BE REMOVED IMMEDIATELY. 5. IF VEHICLES ARE ENTERING OR EXITING THE SITE AT POINTS OTHER THAN THE CONSTRUCTION ENTRANCE(S). FENCING (SEE SECTION 0.4.1) SHALL BE INSTALLED TO CONTROL TRAFFIC. . ,S PER KING COUNTY ROAD STANDARDS, RIVEWAYS SHALL BE PAVED TO THE EDGE ,F R-0-W PRIOR TO INSTALLATION OF THE :QNSTRUCTION ENTRANCE TO AVOID AMAGING OF THE ROADWAY ,· IS RECOMMENDED THAT THE NTRANCE BE CROWNED SO THAT .UNOFF DRAINS OFF THE PAD (OP~I~~~-~; _J UNDERLAY WITH -- GEOTEXTILE FABRIC 12" MIN. 4"-8" QUARRY SPALLS GRAVEL CONS .RUCTION ENTRANCE 15" RISER PIPE (PRINCIPAL SPILLWAY OPEN AT TOP WITH TRASH RACK DEWATERING DEVICE CREST OF EMERGENC !

Where straw mulch for temporary erosion control is required, it shall be applied at a m,n,mum thickness of 2 to 3 inches. 14. Prior to the beginning of the wet season (Oct. 1), all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season. A sketch rr1ap of those areas to be seeded and those areas to remain uncovered shall be subrnitted to the DOES inspector. The DOES inspector can require seeding of additional areas in order to protect surface waters, adjacent properties, or drainage facilities. GATCH BASIN INSERT MAINTENANCE STANDARDS 1.

' ' ' J EROSION AND SEDIMENTATION CONTROL NOTES 1. Approval of tllis erosion and sedimentation control (ESC) plan does not constitute an approval of pern,anent road or drainage desi1Jn (e.g. size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.). 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgradiny of these ESC facilities is the responsibility of the applicant/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the applicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown on this plan are the m1n1mum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g. additional sump pumps, relocation of ditches and silt fences, etc.). 6. The ESC facilities shall be inspected daily by the applicant/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days durin9 the season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.). 8. Any area needing ESC measures, not requiring immediate attention, shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within 48 hours following a storm event. wet 10. At no time shall more than one (1) foot of sediment be allowed to accumulate within a catch basin. All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment-laden water into the downstream system. 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of lhe project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12. Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control rneasures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration systern, the temporary facility must be graded so that the bottom and sldes are at least three feet above the final grade of the permanent facility. A PORTION of the S. W. 1 / 4, SECTION 32, TOWNSHIP 23 N., RANGE 5 E., W.M. PERMANENT SEEDING NOTES 1. Seeding should be done immediately after final shaping if completed during the periods of April 1 through June 30 and September 1 through October 15 (if planted between July 1 and August 31 irrigation may be required). Sites which cannot be seeded during this time period should be protected until the next S!)eding period with mulch. 2. Permanent vegetation may be in the form of grass seed mixtures, sod, or wetlands seed/tuber mixtures. Seed establishment shall include the use of supplemental materials, such as mulch. 3. Site preparation -install all required surface water control measures. 4. Seedbed preparation may include the following: a.) If infertile or coarse textured subsoil will be exposed during grading, stockpile topsoil and re-spread it over the finished slope and roll it to provide a firm seedbed. b.) If construction fills have left soil exposed with a loose, rough, or irregular surface, track walk up slope. c.) If cuts or construction equipment have left a tightly compacted surface, break with chisel plow or other suitable implement. Perform all cultural operations across or at right angles to the slopes (contoured). The seedbed should be firm with a fairly fine surface after roughening. 5. Fertilization -in general, 10-20-20 N-P-K fertilizer at a rate of 90 lbs./acre. Developments adjacent to water bodies and wetlands must use slow release low-phosphorus fertilizer (typical 3-1-2 N-P-K). 6. "Hydroseeding" applications with approved seed-mulch-fertilizer mixtures rnay also be used, as long as tackifier is included. 7. Seeding -apply appropriate mixture to the prepared seedbed at a rate of 120 lbs./acre. Cover the seed with topsoil or mulch no deeper than 1/2 inch. 8. Inspect seeded areas for failure and make necessary repairs and re-seedings immediately. a.) If vegetative cover is inadequate to prevent rill erosion, overseed and fertilize in accordance with soil test. b.) If a stand has less than 40°/o cover, reevaluate choice of plant materials and quantities of lime and fertilizer. Re-establish the stand following seedbed preparation and seeding recommendations, omitting lime and fertilizer in the absence of soil test results. POLYETHYLENE CAP PROVIDE ADEQUATE STRAPPING STABILIZED CONSTRUCTION ENTRANCE MAINTENANCE STANDARDS 1. QUARRY SPALLS (OR HOG FUEL) SHALL BE ADDED IF THE PAD IS NO LONGEi, IN ACCORDANCE WITH THE SPECIFICATIONS. 2. IF THE ENTRANCE IS NOT PREVENTING SEDIMENT FROM BEING TRACKED ONTO PAVEMENT, THEN ALTERNATIVE MEASURES TO KEEP THE STREETS FREE OF SEDIMENT SHALL BE USED. THIS MAY INCLUDE STREET SWEEPING, AN INCREASE IN THE DIMENSIONS OF THE ENTRANCE, OR THE INSTALLATION OF A WHEEL WASH. IF WASHING IS USED, IT SHALL BE DONE ON AN AREA COVERED WITH CRUSHED ROCK, AND WASH WATER SHALL DRAIN TO A SEDIMENT TRAP OR POND. 3. ANY SEDIMENT THAT IS TRACKED ONTO PAVEMENT SHALL BE REMOVED - IMMEDIATELY BY SWEEPING. THE SEDIMENT COLLECTED BY SWEEPING SHALL -6 BE REMOVED OR STABILIZED ON SITE. THE PAVEMENT SHALL NOT BE CLEAN,.D BY WASHING DOWN THE STREET, EXCEPT WHEN SWEEPING IS INEFFECTIVE ANL THERE IS A THREAT TO PUBLIC SAFETY. IF NECESSARY TO WASH THE STREETS, THE CONSTRUCTION OF A SMALL SUMP SHALL BE CONSIDERED. THE SEDIMENT WOULD THEN BE WASHED INTO THE SUMP. 4. ANY QUARRY SPALLS THAT ARE LOOSENED FROM THE PAD AND END UP ON THE ROADWAY SHALL BE REMOVED IMMEDIATELY. 5. IF VEHICLES ARE ENTERING OR EXITING THE SITE AT POINTS OTHER THAN THE CONSTRUCTION ENTRANCE(S), FENCING (SEE SECTION D.4.1) SHALL BE INSTALLED TO CONTROL TRAFFIC. AS PER KING COUNTY ROAD STANDARDS, DRIVEWAYS SHALL BE PAVED TO THE EDGE OF R-0-W PRIOR TO INSTALLATION OF THE CONSTRUCTION ENTRANCE TO AVOID DAMAGING OF THE ROADWAY IT JS RECOMMENDED THAT THE ENTRANCE BE CROWNED SO THAT RUNOFF DRAINS OFF THE PAD ~ R=25.0'~ (OPTIONAL) UNDERLAY WITH -- GEOTEXTILE FABRIC 12' MIN.J 4' -B" QUARRY SPALLS GRAVEL C:JNSTRUCTION ENTRANCE 15" RISER PIPE (PRINCIPAL SPILLWAY OPEN AT TOP 'MTH TRASH RACK DEWATERING DEVICE CREST OF EMERGENCY SPILLWAY .

Where straw mulch for temporary erosion control is required, it shall be applied at a m1n1mum thickness of 2 to 3 inches. 14. Prior to the beginning of the wet season (Oct. 1), all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season. A sketch map of those areas to be seeded and those areas to remain uncovered shall be submitted to the ODES inspector. The DOES inspector can require seeding of additional areas in order to protect surface waters, adjacent properties, or drainage facilities. CATCH BASIN INSERT MAINTENANCE STANDARDS 1. ANY ACCUMULATED SEDIMENT ON OR AROUND THE FILTER FABRIC PROTECTION SHALL BE REMOVED IMMEDIATELY. SEDIMENT SHALL NOT BE REMOVED WITH WATER, AND ALL SEDIMENT MUST BE DISPOSED OF AS FILL ON SITE OR HAULED OFF SITE. 2.
