The information submitted does not provide what we are asking for. Each of these two permit applications shall include the followings: 1. Engineeringflilumination Plans. These plans shall show the horizontal locations for the proposed street lights, and shall show the typical road section for the road. The typical road section shall show the proposed street light poles at setback consistent with the 1993 King County Road Standard (KCRS). 2. King County Bond Quantities Calculations Work Sheets shall be submitted for each project. I hope this provide the necessary clarification so we can move these two permits forward as soon as possible. Should you have any questions, please feel free to call me, in the mean time I will place these two projects on hold pending your re-submittals. Thank you. Mazen Haidar. P.E.

HEARING EXAMINER 20.24.190 -20.24.197 20.24.190 Additional examiner findings -reclassifications and shoreline redesignations. When the examiner issues a recommendation regarding an application for a reclassification of property or for a shoreline environment redesignation, the recommendation shall include additional findings that support the conclusion that at least one of the following circumstances applies: A. The property is potentially zoned for the reclassification being requested and conditions have been met that indicate the reclassification is appropriate; B. An adopted subarea plan or area zoning specifies that the property shall be subsequently considered through an individual reclassification application; C. Where a subarea plan has been adopted but subsequent area zoning has not been adopted, that the proposed reclassification or shoreline redesignation is consistent with the adopted subarea plan; or D. The applicant has demonstrated with substantial evidence that: 1. Since the last previous area zoning or shoreline environment designation of the subject property, authorized public improvements, permitted private development or other conditions or circumstances affecting the subject property have undergone substantial and material change not antiCipated or contemplated in the subarea plan or area zoning; 2. The impacts from the changed conditions or circumstances affect the subject property in a manner and to a degree different than other properties in the vicinity such that area rezoning or redesignation is not appropriate; For the purposes of this subsection, "changed conditions or circumstances" does not include actions taken by the current or former property owners to facilitate a more intense development of the property including but not limited to changing tax limitations, adjusting property lines, extending services, or changing property ownership; 3. For proposals to increase rural residential density, that the proposal meets the criteria in Comprehensive Plan policies R-205 through R-209; 4. For proposals to increase urban residential density, that the proposal meets the criteria in Comprehensive Plan policies U-118 through U-123; and 5. The requested reclassification or redesignation is in the public interest. (Ord. 14047 § 12, 2001: Ord. 4461 § 10, 1979). 20.24.195 Additional examiner findings -preliminary plats. When the examiner makes a decision regarding an application for a proposed preliminary plat, the decision shall include additional findings as to whether: A. Appropriate provisions are made for the public health, safety, and general welfare and for such open spaces, drainage ways, streets or roads, alleys, other public ways, transit stops, potable water supplies, sanitary wastes, parks and recreation, playgrounds, schools and school grounds and all other relevant facts, including sidewalks and other planning features that assure safe walking conditions for students who only walk to and from school; and B. The public use and interest will be served by the platting of such subdivision and dedication. (Ord. 12196 § 38, 1996: Ord. 9544 § 16, 1990). 20.24.197 Additional examiner findings and recommendations -school capacities. Whenever the examiner in the course of conducting hearings or reviewing preliminary plat applications receives documentation that the public schools in the district where the development is proposed would not meet the standards set out in K.C.C. 21A.28.160 if the development were approved, the examiner shall remand to the department of development and environmental services to require or recommend phasing or provision of the needed facilities and sites as appropriate to address the deficiency, or deny the proposal if required by this chapter. The examiner shall prepare findings to document the facts that support the action taken. The examiner shall recommend such phasing as may be necessary to coordinate the development of the housing with the provision of sufficient school facilities, or shall require the provision of the needed facilities. An offer of payment of a school impact fee as required by ordinance shall not be a substitute for the phasing, but the fee is still assessable. The examiner shall recommend a payment schedule for the fee to coordinate the payment with phasing of an impact mitigation fee if the provision or payment is satisfactory to the district. The examiner must determine independently that the conditions of approval and assessable fees will provide for adequate schools. (Ord. 14047 § 13, 2001: Ord. 11620 § 7, 1994: Ord. 9785 § 10, 1991). 20-89 U-117 2. Minimum Density Land zoned for multifamily uses should be converted to non-residential zone categories only after new multifamily sites are identified and rezoned to replace the multifamily housing capacity lost due to the conversion. In accordance with Countywide Planning Policy LU-66(b), King County has included a minimum density requirement in its zoning regulations for all new urban residential development with a zoned density of four or more homes per acre. U-118 King County should apply minimum density requirements to all urban residential zones of four or more homes per acre, except under limited· circumstances such as the: a. Presence of significant physical constraints, or b. Implementation of standards applied to a property through a property-specific development condition, special district overlay, or subarea plan. 3. Increases of Zoning Density While King County supports higher densities in the urban areas, increased densities that would be incompatible with existing neighborhoods or cause significant impacts on roads, services and the environment are discouraged. The following policies will guide decisions on application of densities and proposed rezones. U-119 U-120 U-121 February 2001 Requests for increases In density of urban residential property zoned for one dwelling unit per acre must Include a demonstration that the property does not meet the criteria of Policy U-115. King County shall not approve proposed zoning changes to increase density within the Urban Area unless: a. The development will be compatible with the character and scale of the surrounding neighborhood; b. Urban public facilities and services are adequate, consistent with adopted levels of service and meet GMA concurrency requirements, including King County transportation concurrency standards; c. The proposed density change will not Increase unmitigated adverse Impacts on environmentally sensitive areas, either on site or In the vicinity of the proposed development; d. The proposed density Increase will be consistent with or contribute to achieving the goals and policies of this Comprehensive Plan, and subarea plan, If applicable; and e. The proposal Is consistent with the adopted city comprehensive plan for the Potential Annexation Area where the rezone is located if the proposed density exceeds eight dwelling units per acre. If the city is not planning for urban densities and efficient land use patterns consistent with the Countywide Planning Policies, then this paragraph shall not apply. King County, when evaluating rezone requests for Increases In density, shall notify adjacent cities, special purpose districts and local providers of urban utility services and should work with these service providers on issues raised by the proposal. 2-6 --------- U-122 U-123 King County supports increases in urban residential density through a rezorie or a proposal to Increase density through the density transfer or density incentive programs when the proposal will help resolve traffic, sewer, water, parks or open space deficiencies in the immediate neighborhood. King County shall not support requests for residential density increases on lands located within the outer boundaries of the Noise Remedy Area as identified by Seattle-Tacoma International Airport. Development in the Urban Growth Area at a higher density than normally permitted by zoning will be allowed in exchange for public amenities such as low-income housing, preservation of designated historic features or extra energy conservation measures, or through the transfer of density credits from other parts of the County. U-124 Density Incentives should encourage private developers to provide innovative affordable housing, significant open space, trails and parks; to locate close to transit; to participate In historic preservation; and to Include energy conservation measures exceeding state requirements. 4. Mixed Use Development Mixed use development combines higher density residential units with retail or office uses in the same building or within an integrated development on the same lot. Quality mixed use developments can provide convenient shopping and services to both residents of the development and those who live near by. They can help to build a sense of community, as neighboring merchants and residents get to know each other. Mixed use is traditional in older downtowns and commercial areas, where offices and retail typically occupy the first floor and residences are upstairs. U-125 U-126 U-127 U-128 King County supports Mixed Use Developments in Community and Neighborhood Business Centers, the White Center Unincorporated Activity Center, and in areas designated Commercial outside of Centers . . Design features of Mixed Use Developments should Include the following: a. Integration of the retail and/or office uses and residential units within the same building or on the same parcel; b. Ground level spaces built to accommodate retail and office uses; and c. Off-street parking behind or to the side of buildings, or enclosed within buildings. In a Mixed Use Development where residential and non-residential uses are proposed in separate structures and the residential uses are proposed to be constructed prior to the non-residential uses, the Initial review of the development should be through a process that ensures an integrated design. In a Mixed Use Development, Incentives such as increases In residential density or floor area ratio should be used to encourage the inclusion of public gathering spaces in the site design. 5. Urban Residential Neighborhood Design and InfilVRedevelopment King County residents can enjoy their urban neighborhoods both for their unique character and for the amenities they provide. Outdoor spaces need to be usable, attractive, comfortable, and enjoyable. The design of urban streets, including features such as parking strips, street trees, alleys and off-street parking all contribute to the character of urban neighborhoods. Careful site planning can incorporate neighborhood 2-7 February 2001 R-209 The RA-2.5 zone has generally been applied to rural areas with an existing pattern of lots below five acres in size that were created prior to the adoption of the 1994 Comprehensive Plan. These smaller lots may still be developed individually or combined, provided that applicable standards for sewage disposal, environmental protection, water supply, roads and rural fire protection can be met. A subdivision at a density of one home per 2.5 acres shall only be permitted through the transfer of development credits from property in the designated Rural Forest Focus Areas. The site receiving the density must be approved as a Transfer of Development Credits receiving site in accordance with the King County Code. Properties on Vashon-Maury Islands shall not be eligible as receiving sites. Accessory dwelling units provide opportunities for affordable housing, on-site housing for workers and caretakers, housing for extended family members, and rental income for landowners. However, detached accessory dwelling units function similarly to separate homes on separate lots, and should be treated as such. When a subdivision is proposed for a property that already has a house and a detached accessory dwelling unit, the house and accessory dwelling unit shall count as two units. For example, on an RA-5 zoned 20 acre parcel, which could be subdivided into four lots, the existing primary dwelling and the accessory unit in a separate building shall count as two of the four units allowed on the site. R-210 R-211 Accessory dwelling units in structures detached from the primary dwelling shall be counted as a separate dwelling unit for the purpose of lot calculations under the zoning in place at the time of a proposed subdivision. The King County Residential Density Incentive Program shall not be available for development in the Rural zones. C. Transfer of Development Credits Program The Growth Management Act encourages the use of innovative techniques for land use management. King County has a long tradition of using innovative techniques, including programs promoting transfers of _ .. development credits, to achieve land management goals such as those stated above. To that end, King County promotes the transfer of development rights, or "credits," from land valuable to the public, especially rural and resource areas, to land better able to accommodate growth. The Transfer of Development Credits (TDC) Program allows landowners to voluntarily achieve an economic return on their property while maintaining it in forestry, farming, habitat or parks and open space in perpetuity. It also increases housing opportunities in the Urban Area where urban services and infrastructure can accommodate additional growth. R-212 R-213 R-214 As an Innovative means to permanently preserve lands with countywide public benefit, to encourage higher densities in appropriate areas and reduce residential development capacity in Rural Forest Focus Areas, King County shall continue efforts to implement an effective and focused transfer of density program. The primary intent of the Transfer of Development Credits Program is to reduce development in the Rural Area by encouraging the transfer of development credits from rural lands into the Urban Growth Area. Transfers may also be made among rural sites in some cases. King County supports and shall work actively to facilitate the transfer of development credits to: a. Preserve the rural environment, encourage retention of resource- based uses and reduce service demands in the Rural Area; b. Provide permanent protection to significant natural resources; and 3-13 February 2001 .------------------------------------------------------ c. Increase the regional open space system. The key to a successful transfer of development credits program is the availability of and market for "receiving sites" for development credits. In 1997, King County completed a study examining potential receiving areas in the Urban Area, in rural cities and towns, and also in rural areas where the existing pattern of lots is smaller than five acres in size. The study found there are some unincorporated urban areas that could be suitable to receive development credits, and that most of the more intensely- developed rural areas were not appropriate for additional density due to physical, environmental and infrastructure constraints. The study also concluded that the participation of incorporated cities as receiving areas is essential to the success of a TOC program in King County. King County Code 21 A.36 provides the detailed rules for private property owner to private property owner transfers of development credits. Transfers of development credits are permitted from rural unincorporated areas to urban unincorporated areas. Transfers from urban unincorporated areas to other urban unincorporated land are also permitted to provide an incentive to protect environmentally-sensitive urban land or urban lands valuable to the open space system. King County has also authorized a pilot program to test additional ways to facilitate transfers of development credits, including the creation of a County-managed TOC bank to buy and then sell credits, developing interlocal agreements with cities willing to accept transfers of development credits, and the allowance for transfers from rural or resource lands to other rural lands. The details of these transfer rules are found in King County Code 21 A.55. The two code sections will be consolidated to incorporate the most successful transfer of development credit techniques following evaluation of the pilot program. R-215 R-216 R-217 February 2001 To promote transfers of development credits, King County shall facilitate the transfer of credits from private property owners with sending sites to private property owners with receiving sites, buy and sell development credits through the King County Transfer of Development Credits (TDC) Bank, and work with cities to develop Interlocal agreements that encourage transfers of development credits into cities and, within adopted appropriations. Public amenity funding to enhance the livability of neighborhoods accepting Increased densities should also be part of the program. King County should actively solicit large landowners, within receiving areas, to 'purchase density credits from within the established bank. Properties qualified as sending sites shall provide a permanently protected area of sufficient size to provide public benefit. Priority candidates for sending sites are: a. Lands contributing to the protection of endangered and threatened species; b. Rural Forest Focus Areas; c. Lands that are suitable for Inclusion In and provide Important links to the regional open ·space system, including lands with historical or cultural significance; or . d. Agricultural and Forest Production District lands. Transfers of development credits may be made to receiving sites as follows: Receiving Sites: a. Rural areas zoned RA-5 and RA-2.5 may receive transfers of development credits transfers from the Rural Forest Focus Areas. b. Unincorporated urban areas and incorporated cities may receive transfers of development credit. Preferences should be given for locations within designated Urban Centers, or adjacent to transit stations and park and ride lots. Transfers to Incorporated areas shall be detailed In an Interlocal agreement between the city and county. 3-14 ----------------------------------- R-218 R-219 R-220 Development Credit Calculations a. Portions of urban sending sites that are located within stream, wetland or steep slope sensitive areas and their buffers may only transfer development credits at a discounted rate. b. Development credits transferred from Rural Forest Focus Areas to the Urban Area shall be calculated on a basis of 1 credit for each 5 acres of site area. c. If a portion of a sending site Is being retained for development, the subsequent development must be clustered, and the tract preserved with a permanent conservation easement shall be larger than the developed portion. In the case of lands within the Rural Forest Focus Areas, no more than one dwelling unit per 20 acres shall be retained, and the tract preserved with a conservation easement shall be at least 15 acres In size. DEED RECORDING. Following the transfer of development credits from a sending site, deed restrictions documenting the transfers shall be recorded and notice placed on the title to the sending site parcel. A conservation easement shall be required and shall be documented by a map Indicating the portion of the sending site permanently restricted from future development. King County should increase funding to the TDC bank and seek private and other public funding to strengthen the TDC program and facilitate the transfer of development credits from the Rural Area in order to preserve the rural environment, encourage retention of rural resource-based uses and avoid urban/suburban service demands in the Rural Area. A bond or levy proposal for public funding of a development rights purchase program would be appropriate and should be pursued. Rights purchased through such a program could be sold Into any appropriate urban location . . 0. Nonresidential Uses While low-density residential development, farming.and forestry are the primary uses in the Rural Area, some compatible public and private uses are appropriate and contribute to rural character. Compatible uses might include small, neighborhood churches, feed and grain stores, and home occupations such as small day care facilities or veterinary services. In addition, it may be necessary to locate some public facilities in rural areas, such as utility installations that serve rural homes. Any allowed nonresidential uses should be designed to blend with rural residential development and resource uses. R-221 R-222 Nonresidential uses In the Rural area shall be limited to those that: a. Provide convenient local services for nearby residents; or b. Require location in a Rural area; or c. Support natural resource-based industries; or d.

Staffrpt!masters!PLATFMT.Oct 1997 King County Hearing Examiner C. mSTORYfBACKGRQUND: The Subdivision Technical Committee (STC) of King County has conducted an on-site examination of the subject property. The STC has discussed the proposed development with the applicant to clarify technical details of the application, and to determine the compatibility of this project with applicable King County plans, codes, and other official documents regulating this development. D. THRESHOLD DETEBMlNATION OF ENVIRONMENTAL SIGNIFICANCE: Pursuant to the State Environmental Policy Act (SEPA), RCW 43.21C, the responsible official of the LUSD issued a mitigated threshold determination of non-significance (MDNS) for the proposed development on January 31, 2003. This determination was based on the review ofthe environmental checklist and other pertinent documents, resulting in the conclusion that the proposal would not cause probable significant adverse impacts on the environment provided the following measures are complied with: The base flow control for the stormwater detention system is Level 2 per the .1998 King County Surface Water Design Manual(KCSWDM). To mitigate for existing downstream flooding problems, one of the following options is required: I. The stormwater detention system shall be designed to the Level 3 Flow Control criteria as specified in the 1998 KCSWDM. OR 2. The stormwater detention system shall be designed to the Level 2 Flow Control criteria and the following downstream improvements shall be accomplished either individually or in conjunction with other development proj ects in the area: The 160th Ave. SE downstream conveyance system (from SE 136th ST to approximately SE 142nd St.) shall be upgraded to provide for the 100-year storm capacity. Downstream driveway culverts/ditches and a cross-culvert under 160th Ave. SE shall be improved as needed. Culverts L-8 and L-lO on the west side of 160th Ave. SE, cross-culvert L-ll, and culverts L-12 and L-14 on the east side of 1601h Ave. SE shalJ be improved. The culvert designations are according to the Level I Downstream Drainage Analysis prepared by Daniel Balmelli, PE dated May 26, 2002 and revised Dec 3, 2002. Bank and channel stabilization are also required in the unopened right- of-way for 16200 Ave. SE, in the vicinity of the easterly line of Lot 12, Rich Lea Crest (address 16046 SE 142nd St.). It is estimated that stabilizing and re-grading approximately 50 to 100 feet east of 16046 SE 14200 St., will be adequate to resolve flooding that has occurred at this location. The culverts and channel described are located from the south site boundary to a distance of approximately 2000 feet to 3200 feet downstream. Note that the above ditch and culvert improvements are intended to duplicate the downstream improvements required for the east subbasin of the proposed plat of Evendell LOIPOOI6. Agencies, affected Native American tribes and the public were offered the opportunity to .comment on or appeal the determination for 21 days. The MDNS was not appealed by any party, . including the applicant. E. AGENCmS CONTACTED: 1. King County Department of Natural Resources: No response. 2.

Slopes on the site are generally less than eight percent. 2.. Soils: One surfaces soils are found on this site per King County Soil Survey, 1973. AiC -Alderwood gravely, sandy loam.; 6-15% slopes. Runoff is slow to medium and the hazard of erosion is moderate. This soil has a moderate limitation for foundations, due to a seasonally high water table and slope. It has a severe limitation for septic tank filter fields due to very slow permeability in the substratum . . 3. Wetland/streams: A wetland report prepared by Chad Armour was submitted by the applicant May 30, 2002. The study ideIltified a wetland approximately 7,640 square feet in size in the southwest comer of the site. It was determined that this is a class 3 wetland, which requires a 25 foot buffer. The applicant has placed the wetland and associated buffer in sensitive area tract (SAT) shown as Tract E. The Senior Ecologist for DDES has review the site and the study and is in agreement with the classification. The site lies within the Lower Cedar River sub-basin of the Cedar River drainage basin. 4. Vegetation: This site is primarily pasture grasses. Areas wooded with a second and third-growth mixture of coniferous and broad-leafed trees native to the Pacific Northwest and second-story vegetation and groundcover consists of Northwest native species including salal, sword fern, berry vines, and grasses along the perimeter. . . 5. Wildlife: Small birds and animals undoubtedly inhabit this site; however, their popUlation and species are limited due to nearby development. Larger species may visit this site on occasion. No threatened or endangered species are known to exist on or near the property. 6. Mapped Sensitive Areas: The Sensitive Areas Folio does not identify any mapped sensitive areas as being present on this site. G. NEIGHBORHOOD CHARACTERISTICS: The property lies in a urbanizing area of southeast King County, southeast of the .City of Renton. The neighboring parcels surrounding the site range from approximately one to five acres in size. Adjacent to the north is the developed plat ofWeglin's First Addition (16 lots, approximately 10,500 square feet). The developed plat ofDerryhurst is to the east, with lots approximately 10,300 square feet. The proposed plat and rezone of Even dell (DDES File Nos. LOIP0016 & LOI TY 401) is located to the south. The site itself is currently occupied by a house and outbuildings which will be removed with the development of this proposal. Staffrpt/maatera/PLATPMT.NOV99.doc clc 11/10/99 ~ 3 - H. SIJBDMSION DESIGN FEATIlRES: I. Lot Pattern and Density: The applicant is proposing to utilize the provisions of King County Code 21A.37 (Transfer of Density CreditslRights) to maximize/increase the number oflots on the site. The applicant has acquired density credits for six additional lots. 2. Internal Circulation: The site will be served by an internal road which connects west to east 158tb Avenue Southeast and 160tb Avenue Southeast, which are both neighborhood collectors. 3. Roadway Section: The internal road (Road A) and perimeter (158 tb Ave SE and 160tb Avenue SE) will be constructed to urban standards in accordance with the 1993 King County Road Standards. 4. Drainage: The site is located in the Orting Hills subbasin of the Lower Cedar River basin. The existing site drainage sheet flows from the northeast to the southwest. The site drainage then leaves the site along the south boundary or enters the ditch along the east side 158tb Ave SE. A wetland exists in the southwest comer of the site, shown as Tract E on the proposed plat map. After leaving the site, the flow path continues south in the east ditch along 158tb Ave SE through a series of individual culverts. The path turns east ina ditch within the unopened RJW for SE 136tb ST. Flow continues east to the west ditch along 160tb Ave SE, then turns south along the west side of 160tb Ave SE. The flow continues south along the west side of 160tb Ave SE to a cross culvert at approximately SE 139tb St. (2,450 ft downstream). The drainage then continues south along the east side of 160tb St in a series of ditches and culverts, turning east at approximately SE l42nd St. (2600 ft downstream). Flow continues east through a swale and several culverts to an unnamed tributary to the . Cedar Ri"er within the unopened RJW for I 62 nd Ave SE. Several downstream drainage complaints were evaluated and included in the Levell Downstream Drainage Analysis prepared by Daniel Balrnelli P.E .. Mitigation is proposed for these problems by either a higher flow control requirement or downstream improvements in accordance with the 1998 king County Surface Water Design Manual . (KCSWDM). I. TRANSPORTATION PLANS: I. Transportation Plans: The subject subdivision is not in conflict with King County Transportation plan, nor with the Regional Trails and NonMotorized plans. 2.

A homeowners' association or other workable organization shall be established to the satisfaction ofDDES which provides for the ownership and continued maintenance of the' recreation, open space and/or sensitive area tract(s). 18. Street trees shall be provided as follows (per KCRS 5.03 and KCC 21A.16.050): a. . Trees shall be planted at a rate of one tree for every 40 feet of frontage along all . roads. Spacing may be modified to accommodate sight distance requirements for driveways and intersections. . b. Trees shall be located within the street right-of-way and planted in accordance with Drawing No. 5-009 of the 1993 King County Road Standards, unless King County Department of Transportation detennines that trees should not be located in the street right-of-way . . c. If King County detennines that the required street trees should not be located within the right-of-way, they shall be located no more than 20 feet froin the street right-of-way line. d. The trees shall be owned and maintained by the abutting lot owners or the homeowners association or other workable organization unless the County has adopted a maintenance program. Ownership and maintenance shall be noted on the face of the final recorded plat. e. The species of trees shall be approved by DDES iflocated within the righi-of- way, and shall not include poplar, cottonwood, soft maples, gum, any fruit- bearing trees, or any other tree or shrub whose roots are likely to obstruct sanitary or stonn sewers, or that is not compatible with overhead utility lines. f.

If a perfonnance bond is posted, the street trees must be installed and inspected within one year of recording of the plat. At the time of inspection, if the trees are found to be installed per the approved plan, a maintenance bond must be submitted or the perfonnance bond replaced with a maintenance bond, and held for one year. After one year, the maintenance bond may be released after DDES has completed a second inspection and determined that the trees have been kept healthy and thriving. A landscape inspection fee shall also be submitted prior to plat recording. The inspection fee is subject to change based on the current County fees. . 19. The following have been established by SEPA as necessary requirements to mitigate the adverse environmental impacts of this development. The applicants shall demonstrate compliance with these items prior to final approval. The base flow control for the stonnwater detention system is Level 2 per the 1998 King County Surface Water Design Manual(KCSWDM). To mitigate for existing downstream flooding problems, one of the following options is required: a. The stonnwater detention system shall be designed to the Level 3 Flow Control criteria as specified in the 1998 KCSWDM. St.ttrpt/ma8ter8~PLATPMT.NOV99.doc· clc 11/10/99 -9 - OR b. The stormwater detention system shall be designed to the Leve12 Flow Control criteria and the following downstream improvements shall be accomplished either individually or in conjunction with other development projects in the area: The 160th Ave. SE downstream conveyance system (from SE 136th ST to approximately SE 142nd St.) shall be upgraded to provide for the 100-year storm capacity. DoWnstream driveway culverts/ditches and a: cross-culvert under 160th Ave. SE shall be improved as needed. Culverts L-S and L-l 0 on the west side of 160th Ave. SE, cross-culvert L-ll, and culverts L-12 and L-14 on the east side of 160th Ave. SE shall be improved. The culvert designations are according to the Levell Downstream Drainage Analysis prepared by Daniel Balmelli, PE dated May 26, 2002 and revised Dec 3, 2002. Bank and channel stabilization are also required in the unopened right-of-way for 162nd Ave. SE, in the vicinity of the easterly line of Lot 12, Rich Lea Crest (address 16046 SE l42nd St.). It is estimated that stabilizing and re- grading approximately 50 to 100 feet east of 16046 SE 142nd St., will be adequate to resolve flooding that has occurred at this location. The culverts and channel described are located from the south site boundary to a distance of approximately 2000 feet to 3200 feet downstream. Note that the above ditch and culvert improvements are intended to duplicate the downstream improvements required for the east subbasin of the proposed plat of Even dell LOIPOOI6. OTHER CONSIDERATIONS: 1. The subdivision shall conform to KCC 16.82 relating to grading on private property. 2.

General description ofthe site (circle one): Flat, roDing, hilly, steep slopes, mountainous, other _______ _ b. What is the steepest slope on the site (approximate percent slope)? The steepest slope on site is approximately 5 percent. c. . What general types of soils are found on the site (for eumple, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The existing soil type is A1derwood Gravelly Sandy Loam (AgC) according to the King County SCS Soils Maps. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. To our knowledge, there are no indications or history of unstable soils on the site or in the immediate vicinity. e. Describe the purpose, type, and approximate quantities of any fiDing or grading proposed. Indicate source of fill. The type and purpose for any filling and grading (on-and off-site) will be for the construction of public roads, associated utilities, and storm drainage. The off-site improvements will be half street improvements along 15S'" Avenue Southeast and 160'" Avenue Southeast and approximately \,000 feet of sanitary sewer on \5S'" Avenue Southeast. For further information, see the attached Preliminary Storm Drainage and Utility Plan. The quantity of fill is unknown at this time but may range from 2,000 to 3,000 cubic yards. All fill will be created from on-site cuts except for any necessary import for road beds and utility trenches. -4- EVALUATION FOR AGENCY USE ONLY TO BE COMPLETED BY APPLICANT f. Could erosion occur as a result of dearing, construction, or use? If so, generally describe. Erosion could occur as a result of clearing and/or construction of this project. However, King County requires that an erosion control plan be prepared and implemented to minimize impacts. This could include temporary storm ponds, rock check dams, mulching, temporary conveyance ditches, straw bales, and/or mirafi fence, along with hydroseeding, if necessary. g. About what percent of the site will be covered with impervious surfaces after project construction? Approximately 60 percent of the site will be covered with impervious surfaces, which include asphalt, concrete, and structures. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any. As discussed in Section F above, King County will require that an erosion control plan be prepared and implemented for this project to control erosion. All sensitive areas (wetlands) will remain tmdisturbed, .and appropriate silt fencing and/or temporary interceptor ditches will be provided. ·5· EVALUATION FOR AGENCY USE ONLY TO BE COMPLETED BY APPLICANT 2. Air a. What types of emissions to the air would result from the proposal (i.e., dust, automobile odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and' give approximate quantities if known. During construction of the project, typical air emissions, such as dust or heavy equipment exhaust, will be created. However, this will be a short-tenn impact. Following the construction of the project, residential air emissions such as automobile exhaust, wood burning stoves (if applicable), natura1 gas emissions for heating, etc., will be generated. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. To our knowledge, there are no known off-site sources of emissions or odors that would affect this project. c. Proposed measures to reduce or control emissions or other impacts to air, if any. State regulations with respect to equipment emission controls will be implemented and inspected by King County during the construction phase. During dry weather, watering of disturbed areas will be completed to reduce dust created by construction equipment. With respect to the final phase of the project, all homes and associated automobiles must adhere to State regulations and guidelines to control and/or reduce emissions. -6- EVALUATION FOR AGENCY USE ONLY TO BE COMPLETED BY APPLICANT 3. Water a. Surface: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. A Type III wetland is located in the southwest comer of the site (Tract E). This wetland eventually discharges water into an open ditch along 15 go Avenue Southeast. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described water? If yes, please describe and attach available plans. Yes, on-site improvements will be constructed within 50 feet of the wetland. Also, any required improvements to 158m Aven)le Southeast wilLbe ooost"I!1edwithin 15 to 20 feet of the existing wctland (see attached plans). 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. None. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities, if known. No. 5) Does the proposal lie within a tOO-year floodplain? If so, note location on the site plan. No. -7- EVALUATION FOR AGENCY USE ONLY TO BE COMPLETED BY APPLICANT 6) Does the proposal involve any discharges of waste materi8ls to surface water? If so, describe the types of waste sod anticipated volume of discharge. No. b. Ground: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities, if known. Not to our knowledge. -8- EVALUATION FOR AGENCY USE ONLY ,--------------------- TO BE COMPLETED BY APPLICANT 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals ••• ; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of' houses to be served (if appli- cable), or the number of animals or humans the system(s) are expected to serve: . The project site will be served by a public sewer system extended to the site from the south, and therefore, waste material will not be discharged into the groundwater. c. Water Runoff: 1) Describe the source of runoff (including stormwater) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. The source of runoff created from the site will be stormwater. The project proposes to collect stormwater through a series of catch basins and conveyance pipes to a storm detention facility located at the southwest corner of the site (Tract B). The storm drainage facility will be an open combined wetldetention pond designed per the 1998 King County Surface Water Design Manual. From the storm pond, water will be released through the existing wetland and then into the existing open ditch system on 158'" Avenue Southeast. For a more detailed description of the storm system, please reference the attached Level I Storm Drainage Analysis. 2) Could waste materials enter ground or s·urface waters?

Our wetland functional assessment form is presented in Appendix B. SUMMARY OF FINDINGS KBS III, LLC proposes to improve the 4.32-acre (ac) Hamilton site before selling it to a homebuilder. The site is located in the Renton area of King County, Washington at 13305 -160th Avenue SE. A single Class 3 wetland covering 0.18 ac or 7,640 square feet (sf) is located in the southwest corner of the site. A few widely scattered red alder (Alnus rubra, FAC) trees that are dying and grazed pasture grasses dominate it. Water that accumulates in this wetland during the rainy season flows off site to the south via an adjacent roadside ditch. The wetlands small size, simple plant community, and on-going grazing pressure limit its functional value. The minimum buffer setback for Class 3 wetlands is 25 feet. Buildings, pasture, and upland forest dominate the remainder of the site. SITE DESCRIPTION The rectangular-shaped Hamilton site covers 4.32 ac and is located at 13305 -160th Avenue SE in Section 14, Township 23 North, Range 5 East in the Renton area of King County, Washington (Figure I). The site is composed ofa single tax lot (366450-0100) that support a single-family home, associated outbuildings, lawn, pasture, deciduous forest, and wetland (Figure 2). Several cows and a bull were present on site at the time of our site visits. The cattle have complete access to almost the entire site and the grass in the pasture and the grass .and herbs in the forest are heavily grazed. Consequently, the soil in some areas is exposed and cut up by their hooves. Site topography is relatively level with site elevations ranging from a low of about 505 feet to a high of about 523 feet above mean sea level. The northern two-thirds of the site is relatively level and supports all of the improvements, including the pasture. The southern third of the site slopes gently (range 2 to 4 percent) generally from north to south and is the location of the deciduous forest. Land use adjacent to the site is similar to the site. Single-family residential homes on small to medium-sized lots surround the site. BACKGROUND INFORMATION We understand that KBS III, LLC intends to subdivide the site and construct roads and utilities before selling the improved site to homebuilders. We reviewed existing available maps at the King County Department of Development and Environmental Services to assess the potential for wetlands or streams to be present on or adjacent to the site. According to Wetland Map 9 in the Sensitive Areas Map Folio, there are no wetlands located on or adjacent to the site (King County, 1990). The closest mapped wetlands are Wetlands 2 and 3 in the adjacent May Creek sub-basin. They are located somewhat more than y.. mile northeast of the site. Stream Map 9 in the same folio HamiltonlDelineation Report.doc 2 04/30/02 Chad Annour, LLC i--' I I I I I I I I I I I I I I I I Wetland Assessment and Delineation King County, Washington -----------------------------, KBS III, LLC indicates that no streams are located on or in the near vicinity of the site, The closest known salmon-bearing streams are the Cedar River and May Creek, which are located approximately 6,000 feet south and north of the site respectively. According to the Flood Insurance Rate Map the site is mapped as Zone X indicating that it is outside the SOO-year floodplain (FEMA, 1989). SITE CONDITIONS We visited the site on March 28, 2001 and May 4, 2001 to assess vegetative, soil, and hydrologic conditions on the site. We flagged one wetland area on the site and Center Pointe Surveying surveyed the location of the flagged wetland boundaries. The following subsections of the report depict the results of our efforts. On-Site Wetland The site contains a single 7,640 sf (0.18 ac) wetland that is located entirely on the site. The wetland is located in a slight depression in the southwest corner of the site. The depression appears to accumulate water during prolonged periods of precipitation during the rainy season. The accumulated water drains off site to the south via a small ditch. (Figure 2). The wetland is dominated by widely spaced red alder trees and grazed pasture grasses (Appendix A; Plot ID SP-2). Because there were no inflorescence (Le., flowering structures) on the grasses, we were not able to identify the individual grass species. However, we assumed that the grasses are hydrophytic based on topography, soils, and hydrology indicators. Other plant species present in lesser amounts in or adjacent to the wetland include big-leaf maple (Acer macrophyllum, FACU) trees, Himalayan blackberry (Rubus disc%r, F ACU) and Indian plum (Oem/aria cerasijormis, F ACU) shrubs, and soft rush (Juncus effusus, F ACW). The upland-adapted plants generally grow on hummocks or on the upland around the perimeter of the wetland. All of the tree species in the wetland were dying presumably because they are rooted in an area subject to seasonal ponded water. The presence of these upland-adapted species suggests that this area of the site was once likely upland and the wetland is a recent phenomenon. The soil on the site is mapped as Alderwood gravelly sandy loam, 6 to IS percent slopes (Figure 3). In the wetland, the soil appears to resemble the mapped soil unit as modified by prolonged saturation. The soil to a depth of more than 12 inches is a black (10YR2/l) gravelly sandy loam without mottles. Because cattle have full access to this area, the soil is exposed in much of the wetland. Alderwood gravelly sandy loam soil is a non-hydric soil (NRCS, 1996). Wetland hydrology was present during both of our March and May site visits .. The depth to freestanding water was 4 inches below ground surface (bgs) and it was saturated within 2 inches of the surface. Standing water was "present in hoof prints and tire tracks. During our March site visit excess surface water drained off site to the south via a small roadside ditch. Hamilton/Delineation Report.doc Chad Annour, LLC 3 04/30/02 I I I I I I I I I I I I I I I I I I Wetland Assessment and Delineation King County, Washington Wetland Functions KBS III, LLC We performed a functional assessment of the wetland using qualitative observations. Wetland functions assessed include shoreline protection, hydrologic support, storm/flood water abatement, groundwater exchange, water quality improvement, and natural biologic support. Field observations suggest that the wetland appears to provide low to moderate wetland functions (Appendix B). The wetlands relative small size, simple plant community, and continual disturbance by cattle tends to limit its functional value. Wetland Classification The wetland is classified as a palustrine emergent wetland (Cowardin et aI., 1979) (the trees present in the wetland are located on upland hummocks and are dying). Because the wetland is smaller than one acre but greater than 2,500 sf and has two or fewer classes of vegetation, it is classified as a Class 3 wetland (King County, 2000). Wetland Buffers The minimum buffer setback for Class 3 wetlands is 25 feet (King County, 2000). The County may allow buffer averaging as long as it provides additional protection to wetlands or enhances their function and as long as the total area of the buffer is not decreased. On-Site Uplands The remaining 4.14 ac of the Hamilton site is composed of uplands. We did not observe any indications of wetlands or streams in the upland areas. Pasture Grazed or mowed grasses dominate the pasture and residential areas of the site. For these reasons, we were not able to identify the species of grasses present in these two locations. We assume that they are non-hydrophytes based on the presence of non-hydric soils and the lack of wetland hydrology. Other plant species present in the pasture include white clover (Trifolium repens, FACU), common plantain (Plantago major, FACU+), and common dandelion (Taraxacum officina/e, F ACU) (Plot ID SP-3). The soil at this location resembles the mapped soil unit with a surface layer of very dark brown (10YR2/2) gravelly sandy loam over dark brown (10YR3/3) gravelly sandy loam (Snyder, et aI. 1973). There was no hint of mottling in this soil profile. There was no indication of wetland hydrology to a depth of more than 16 inches. This sampling point is located on the crest of a slight hill. Deciduous Forest Native and non-native trees and native shrubs dominate the deciduous forest. Big-leaf maple trees and Indian plum and California hazel (Cory/us cornuta, FACU) shrubs dominate the forest (Plot ID SP-1). Other plant species also observed in the deciduous HamiltonlDelineation Report.doc 4 04/30102 Chad Annour, LLC I I I '. I I I I I I I I I I I I I I Wetland Assessment and Delineation King County, Washington KBS Ill, LLC forest include red alder and English holly (flex aquifolium, FACU) trees. There are no grasses or herbs present in the forest. The cattle presumably removed those that were once present. The soil in the deciduous forest resembles the mapped soil unit. It is composed of very dark grayish brown (lOYR3/2) gravelly loam to a depth of more than 16 inches. There was no indication of reducing conditions in this soil profile. When we first visited the site in late March, we observed freestanding water in the test hole 12 inches bgs and saturated soil 8 inches bgs. When we revisited the site in early May, neither standing water nor saturated soils were present within 16 inches of the soil surface. There also was no indication of oxidized root channels. Based on our May observations and the lack of hydrophytic vegetation and hydric soils, the wetland hydrology indicators present in March were not typical. CONCLUSIONS Most of the Hamilton site consists of uplands dominated by grazed or mowed grasses and a deciduous forest. The forest is not typical of Western Washington deciduous forests because cattle grazing has removed all of the herbaceous grasses and forbs. A single wetland covering a total of 7,640 sf or 0.18 ac is present in the southwest comer of the site. Based on the surrounding vegetation and topography, it was likely upland before the soil was compacted by cattle. Although a ditch in the wetland adjacent to the southern site boundary allows accumulated water to flow off site via the roadside ditch, compacted soil and the road likely promote standing water during the rainy season. This wetland contains characteristics typical of Class3 wetlands. The minimum buffer setback for Class 3 wetlands is 25 feet.

After we arrived at the site, we traversed the entire site to look for indications of wetlands such as depressions and ditches. We also looked for the presence of plant species that tend to favor wetland conditions. We used the Routine On-site Detennination method detailed in the U.S. Anny Corns of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987) and Washington State Wetlands Identification and Delineation Manual (Ecology 1997). We identified plant species using the Flora of the Pacific Northwest (Hitchcock and Cronquist 1973) and A Field Guide to the Common Wetland Plants of Western Washington and Northwestern Oregon (Cooke 1997). The associated indicator status for each plant species was determined using the National List of Plant Species That Occur in Wetlands: Northwest [Region 9] (Reed 1988, updated in 1993). We referenced the Environmentally Sensitive Areas regulations (King County 2000) to assess applicable wetland issues. Soils were identified using the Soil Survey of King County Area, Washington (Snyder et. ai, 1973). We referenced the Natural Resource Conservation Service (NRCS) web page to detennine if mapped soils or soils identified on site were hydric or non-hydric (NRCS, 1996). We marked the location of sampling points and wetland boundaries with consecutively numbered flagging and/or stakes with indelible ink. Following our site visit, Centre Pointe Surveying surveyed the flagged boundaries to detennine the exact location of the sampling points and wetland boundaries. Centre Pointe Surveying also calculated the wetland areas. Wetland detennination and wetland rating fonns completed by Chad Annour are presented at the end of this appendix. Indicator categories shown on the field data forins are defined as follows: F ACW (facultative wetland) FAC (facultative) FACU (facultative upland) UPL (upland) Nl >99% 67%-99% 34%-66% \%-33% <1% No Indicator A positive or negative sign more specifically defines the regional frequency of occurrence for FACW, FAC, or FACU species in wetlands. A positive sign (+) indicates a frequency toward the higher end of the category. Conversely, a negative sign (-) indicates a frequency toward the lower end of the category.

D.D.E.S. Exhibit No . ..J./-.:R>--__ _ Item No. Lc::::.a~~ Received 2,-,'l' ~ King County Hearing Examiner As requested in the plat screening transmittal letter dated July 15,2002, this supplemental Level I Downstream Drainage Analysis has been prepared to respond to the additional information requested by King County. The additional information requested is as follows: I. King County's review of the Level I Downstream Drainage Analysis indicates that there appears to be at least two subbasins on the site that combine into one drainage facility at post development conditions. If so, this condition would require a drainage adjustment from Core Requirement No. I of the 1998 King County Drainage Manual. 2. King County requests that the downstream drainage complaint at \3814 160th Avenue Southeast, as well as other complaints shown in the Evendell Level I Drainage Analysis, be evaluated as necessary for the plat of Hamilton Place. . 3. King County requests that alternatives to the discharge proposed into the wetland be evaluated, and incorporate a level spreader dispersion system into the conceptual drainage pIan. In response to comment No.1, it is our opinion that the site contains only one subbasin which drains to the downstream drainage system. However, a portion of the site sheetflows across property directly to the south of the site, prior to entering the downstream system which consists of an open-ditch and culvert system along the east side of 158th Avenue Southeast. Since these flows will be conveyed to the detention facility located at the southwest cOmer of the project site in the developed conditions, and will therefore, no longer sheet flow across the adjacent property to the south, King County considers this a diversion. Therefore, a drainage adjustment has been prepared to address this condition. Included in the drainage adjustment is a copy of a portion of the Upstream/Downstream Tributary Area Map indicating the portion of the site which currently sheetflows across the southerly property prior to discharging into the 158th Avenue Southeast system. In response to comment No.1, additional information has been obtained from King County to evaluate the drainage complaint at 13814 160th Avenue Southeast. Since this complaint was identified as a citizen request, this information was not previously available. In addition to this document, two other claims, hoth located at 14028 160th Avenue Southeast, were obtained from King County. A summary of these claims and citizen action requests are summarized below. Citizen Action Request from Brett Bowden Address: 13814160" Avenue Southeast Date: 10/05/99 This citizen action request indicates that King County was requested to clean a ditch, presumably in front of Bowden's residence. The document indicates that King County mowed the slope of the ditch and thc action was closed on 8/2312000. Citizen Action Request from Brett Bowden Address: 13814160" Avenue Southeast Date: 11113/1001 This citizen action request indicates that King County was requested to address a drainage ditch which was plugged presumably adjacent to the resideot' s home. The document indicates that King County Vectored and flushed the system, and the action was closed on 12/14/200 I. Claim No. 21860 Claimant: Marshal M. Brenden address: 14028160" Ave. SE Date: 1/25/97 This claim indicates that King County Maintenance Division had been cleaning, lining and improving the drainage ditches on both sides of 160th Avenue Southeast above the claimants property, and that these improvements caused the drainage water to be diverted to the culvert in front of the claimants property and flooded the lower floor of the home. The claim also states that King County and/or others diverted all waters draining on the west side of 160th Avenue Southeast by the use of a culvert constructed under the roadway to the east side of 160th Avenue Southeast, thereby increasing the stonnwater in the east ditch. King County's response to this claim dated September II, 1998, states that King County staff did not locate a plugged pipe and indicated that there was, apparently, too much water flowing through the driveway culvert to handle the heavy flows. King County also indicates that the claimant's property is located below the road with no provisions to address possible overflow of the roadside ditch. King County's recommendation was to deny the claim since the ditch cleaning and . improvements completed by King County was north of the claimant's property, and none of the activities altered water flows. King County also indicated that the IS-inch drainage culvert along the front of Brenden's property did not have a history of previous or subsequent problems at this location. King County also indicates that the drainage system on 160th Aveoue Southeast is being reevaluated for possible improvements. Gaim No. 31249 Claimant: Chad L. Meyers Address: 14028 160th Avenue Southeast Date: 1129/02 This claim by Chad L. Meyers states that the ditch/drain on the county maintained road overflowed and flooded the garage and lower level of the residence. The claimant provides a two- page summary of telephone calls and discussions with King County requesting assistance in resolving the flooding problem. Photographs of flooded areas of the home are also included in the claim. King County's March 27, 2002, response to the claim recommends that the claim be denied. King County staff's investigation confinns that installation of the 18-inch enclosed drainage '/ system extending across the frontage of the claimant's property appeared to have been constructed without any valid right-of-way use pennits authorizing installation of the pipe. King County staff indicates that the pipe is most likely undersized and cannot bandle flows from heavy stonn events. King County indicates that they recommended to Mr. Meyers that he check his purchase paperwork to determine if the known flooding problem was disclosed. The response indicates that county engineering staff have reviewed the site, assigned tracking no. (4-1032) to the project, and are currently designing an upgraded system to correct the problem created by the improper pipe installation. In summary, the citizen action requests by Bret Bowden included minor maintenance work which appears to have been completed by King County as requested by the request forms. The claims by Brenden and Meyers, dated 1996 and 200 I, were claims of an overflowing ditch or plugged culvert located at the same residence. The letters from King County indicatc that these claims were denied since King County did not have any responsibility or liability. The information also indicates that the existing IS-inch drainage culvert in front of the claimant's property was apparently installed without any permits, and appeared to be undersized for the flow. King County's March 27, 2002, letter also indicates that King County is currently designing an upgraded system to correct the problem created by the improper pipe installation. Based on the above information, it appears that this problem will be or has been corrected by King County. The recently completed Level 3 downstream drainage analysis for Evendell Plat was also reviewed as part of this supplemental study. The results of this analysis indicate that several culverts in the ditch downstream of the site along I 60th ave s.e.may need to be upsized as mitigation for development of the Evendell Plat or level 3 flow control may be needed. In response to comment No. J, the Conceptual Drainage Plan has been revised to incorporate a level spreader/dispersion system at the outlet of the stonnwater facility to more evenly discharge drainage flows into the existing wetland as requested by King County.

Meyers IAmount: $6.402,61 Thank you for your February 12,2002 email requesting comments and a recommendation concerning the above-referenced claim filed against King County. The claimant alleges County responsibility for flooding damage to the garage and lower level of a residence located . at 14028 160th Avenue Southeast, which occurred on November 14, 2001 and again on December 13, 2001 between 8:00 AM and 5:00 PM. My staff has reviewed this claim and provides the following findings: Incident Confirmation: A query ofthe Citizen Action Request database produced CAR 01- 005097, received from the claimant on November 30,2001 at 2:55 PM, which stated "ditch plugged from last rain, had water in basement." CAR 01-005343 and 01-5405, which were received on December 13th and 14th also confirmed the incident. Damage Confirmation: Roads staff did not confirm damage to the Meyers' residence. Used sandbags were, however, located on the north edge of the property, which would indicate a flooding problem. Recommendation: Staff recommends this claim be denied. Roads staff believes there is no liability on the part of King County. Second Party Liability: Please note Brenden Marshall, Jr. (former owner), filed a claim for flooding damage (Claim 21860), which occurred on December 31,1996.

Brenden/Amount: $5.505.00 I Thank you for your February 5, 1997 memorandum requesting comments and a recommendation concerning the above· referenced claim filed against King County. This claimant alleges damage to various pieces of personal property due to King County Maintenance cleaning, piping and otherwise improving the drainage ditches on both sides of 160" Avenue Southeast, above his property at #14028. This work caused the drainage water to be diverted to the culvert at his property site rather than some waters to be absorbed by properties above his. The flooding incident reportedly occurred on December 31,1996, between 8:00 p.m. and 10:00 p.m. i . .. -, My staff has reviewed this claim and the findings are as follows: , !

Kent, W A 98032 RE: Hamilton Place Subdivision KCSWDM Adjustment Request (File No. L02V0098) Dear Applicant and Engineer: The Land Use Services Division, Engineering Review Section, has completed review of the adjustment request for the Hamilton Place subdivision. You are requesting approval for an adjustment from the 1998 King County Surface Water Design Manual (KCSWDM) Core Requirement No.1, 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 Hamilton Place subdivision is located between 158 th and 160th Avenues SE at SE 133 rd Street. The 23 lot, 4.3 acre, proposed Hamilton Place subdivision is filed under Land Use Services Division (LUSD) file number L02POOII. 2. The Hamilton Place subdivision is located in the Orting Hills subbasin of the Lower Cedar River basin. The site is subject to the Level Two flow control and Basic water quality requirements of the 1998 KCSWDM. 3. The rectangular site slopes gently from the northeast to the southwest. Existing sheetflow either migrates to the ditch on the east side of 158th Avenue SE or crosses the south property line onto the adjacent parcel. Sheetflow that crosses onto the adjacent parcel to the south eventually reaches the ditch on the east side of 158 th Avenue SE and recombines with the rest of the site's flow. The adjacent off-site area to the north, south of SE 132 nd Place, supplies upstream tributary flow 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 near the southwest comer of the site. The allowed release would then be dispersed into the adjacent wetland area that drains to the ditch on the east side of I58th Avenue SE. Nuisance sheetflow across the southern property line onto the adjacent parcel would be significantly reduced. A slight increase in flow will be experienced in approximately 500 feet of the ditch on the east Hamilton PlaceIL02V0098 January 9, 2003 Page 2 00 side of l58th Avenue SE inunediately downstream from the southwest property cormer. The conceptual drainage plan indicates that frontage improvements on l60th Avenue SE are included. 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 some conveyance restrictions and drainage complaints associated with the natural discharge location. This downstream conveyance path is shared by the Evendell Plat (L01P0016) which was conditioned through SEP A to provide downstream drainage path improvements. Through future plat or SEP A conditions, it is anticipated that Hamilton Place will be contributing to downstream conveyance improvements or providing for Level Three flow control as mitigation. 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 facility draining to the east side of158th Avenue SE with the following conditions: 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 Two flow control standard in the 1998 KCSWDM unless modified by plat or SEPA conditions. A 10 to 20 percent volumetric factor of safety must be applied to all storm events requiring detention. 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 off site drainage facilities must be located in a public right-of-way or storm drainage tract dedicated to King County . . 5. Additional storm drainage requirementsjdentified by SEP A or the plat hearing review will apply to this project. If you have any further questions regarding this KCSWDM adjustment or the design requirements, please contact Mark Bergam at (206) 296-7270. .

A Level I downstream drainage analysis was prepared for the project and reviewed by King County staff. A plat screening letter was received on July 15, 2002, requesting a drainage adjustment from Core Requirement No .. 1 of the 1998 KCSWDM due to the presence of two existing on-site subbasins which will be combined into one drainage facility as part of the proposed development. After reviewing this information, the existing topographic survey and the downstream drainage area map, it is apparent that ahhough all of the surface water runoff from the project site drains in a northeast to southwest direction into a single downstream drainage basin, a portion of the site's runoff drains across property just south of the project site eventually combining into the downstream drainage system several hundred feet south of the project in the existing condition. Under the developed condition, this surface water runoff will be collected and discharged to the storm facility located in the southwest comer of the site, thereby, diverting flows from discharging across the property just south of the property. As requested in the July 15, 2002, plat screening letter, we are requesting an adjustment from Section 1.2.1 of the 1998 King County Surface Water Design Manual which states "A proposed project that proposes to construct or modify existing drainage facilities must be discharged at the natural location so as to not divert onto or away from the adjacent downstream properties." Section 1.4.2 under criteria for granting adjustments states "Adjustments to the reqUirements in this manual may be granted provided that granting the adjustment will achieve the follOWing: . · . Mr. Randal Parsons King County Department of Development and Environmental Services -2-October 22, 2002 a. Produce a compensating or comparable result that is in the public interest, and b. Meet the objectives of safety, functlori, appearance, and environmental protection and maintainability based on sound engineering judgment. Based on the results of the Level J Downstream Drainage Analysis, we believe that our request for an adjustment to Section 1.2.1 of the drainage manual can be justified. To assist you in processing this drainage adjustment application, the following plans and documentation are enclosed for your review: I. One completed Surface Water Design Manual Requirement/Standards Adjustment Request Form 2. Two copies of the Level I Downstream Drainage Analysis completed for the project. 3. Two copies of the Conceptual Storm and Utility Pian Prepared for the project showing existing site contours and the proposed stormwater system. 4. Two copies of a portion of the upstream!dpwnstrearn drainage basin map showing the area to be diverted. 5. Two copies of the adjacent lot ownership map showing the site location and surrounding properties. 6. One check for the current fee for the drainage adjustment request. The topography of the existing site is such that surface water runoff generally drains across the site in a northeast to southwest direction by sheetflow ultimately discharging into a roadside ditch along the east site of J5S th Avenue Southeast. A portion of the site (approximately I.S acres) sheetflows across adjacent property to the south prior to discharging ioto the existing ro3dside ditch along ISSth Avenue Southeast. Under the proposed development pian, all stormwater runoff from the project site will be collected and conveyed to a wet/detention pond located at the southwest comer of the site, across a small wetland and then into the existing roadside ditch along ISSth Avenue Southeast at the southwest comer of the site. Under the developed condition, the portion of the site which sheetflows across the southerly property and into the existing roadside ditch, will be diverted and discharged into the 15Sth Avenue Southeast ditch at the southwest comer of the site. Although all surface water runoff from the proposed project will ultimately discharge to the saine downstream drainage channel, a drainage adjustment is required since stormwater runoff from the developed project will not discharge into the channel at the same location as it does in the undeveloped condition. Mr. Randal Parsons King County Department of Development and Environmental Services -3- Our justification for the requested adjustment is as follows: October 22, 2002 a. The proposed adjustment produces a compensatory or comparable result that is in the public interest because of the following: I. The proposed adjustment will not result in an increase of drainage flows to the downstream drainage system by diverting the developed flows further to the west within the existing roadside ditch. The same amount of tributary area and stormwatcr flow will discharge into the existing roadside ditch under the proposed developed condition as it does under existing conditions. The only difference will be that the +/-1.8 acres of the site's existing drainage which' currently sheetflows across property to the south prior to discharging into the roadside ditch will now enter the existing ditch approximately 300 to 700 feet upstream within the ditch system. 2. The proposal will not increase the peak runoff rate of discharge from the overall project site since all drainage flows from the project will be collected and conveyed to the proposed drainage facility within the same drainage basin which will be designed to provide level II detention prior to discharging off site into the downstream system. 3. The level I downstream drainage analysis attached with this submittal includes a complete description of the upstream and downstream drainage systemsfor the project. The Upstream/Downstream Drainage Map included in the submittal shows the area of the project site that will be diverted from the easterly subbasin of the site to the westerly subbasin for detention and treatment prior to discharging into the existing roadside ditch along 15811> A venue Southeast. b. The proposed adjustment meets the objectives of safety, function, appearance, and environmental protection and maintainability based on sound engineering judgment because of the following: The proposed storm drainage detention and water quality treatment system will be designed in accordance with the 1998 King County Surface Water Design Manual for level Ii flow control and water quality treatment prior to discharging to the downstream drainage system. Since all stormwater runoff from the property will be collected and conveyed to the stormwater detention and water quality treatment facility prior to discharging off site and no increase in drainage flows will occur to the downstream drainage system, no significant impacts to the downstream drainage system will be created as a result of the proposed adjustment. Mr. Randal Parsons KingCoumy -4-October 22, 2002 Department of Development and Environmental Services 2. The granting of the proposed adjustment by King County would not alter the appearance and maintainability of the proposed drainage System. The portion of the existing site which currently sheetflows across the southerly property, ultimately drains to the same downstream drainage system as the remainder of the site and to the same downstream drainage system under the developed condition. Co1lecting this portion of runoff and routing it to the southwesterly portion of the site into the proposed stonnwater facility will eliminate the need for a separate detention water quality treatment system for the easterly portion of the site. Discharge of stonnwater flows from the proposed drainage facility will ultimately discharge to the southwest corner of the site into the existing roadside ditch along 15S th Avenue Southeast and continue in a southerly direction similar to existing conditions without creating any increased impacts to the downstream system.

The proposal will not increase the peak runoff rate of discharge from the overall project site since all drainage flows from the project will be collected and conveyed to the proposed drainage facility within the same drainage basin which will be designed to provide level II detention prior to discharging off site into the downstream system. 3. The level I downstream drainage analysis attached with this submittal includes a complete description of the upstream and downstream drainage systems for the project. The Upstream/Downstream Drainage Map included in the submittal shows the area of the project site that will be diverted from the easterly subbasin of the site to the westerly subbasin for detention and treatment prior to discharging into the existing roadside ditch along 158 th Avenue Southeast. b. The proposed adjustment meets the objectives of safety, function, appearance, and environmental protection and maintainability based on sound engineering judgment because of the following: The proposed storm drainage detention and water quality treatment system will be designed in accordance with the 1998 King County Surfuce Water Design Manual for level II flow control and water quality treatment prior to discharging to the downstream drainage system. Since all stormwater runoff from the property will be collected and conveyed to the stormwater detention and water quality treatment facility prior to discharging off site and no increase in drainage flows will occur to the downstream drainage system, no significant impacts to the downstream drainage system will be created as a result of the proposed adjustment. Mr. Randal Parsons King County October 22, 2002 Department of Development and Environmental Services 2. The granting of the proposed adjustment by King County would not alter the appearance and maintainability of the proposed drainage System. The portion of the existing site which currently sheetflows across the southerly property, ultimately drains to the same downstream drainage system as the remainder of the site and to the same downstream drainage system under the developed condition. Collecting this portion of runoff and routing it to the southwesterly portion of the site into the proposed stormwater facility will eliminate the need for a separate detention water quality treatment system for the easterly portion of the site. Discharge of stormwater flows from the proposed drainage facility will ultimately discharge to the.southwest comer of the site into the existing roadside ditch along l58th Avenue Southeast and continue in a southerly direction similar to existing conditions without creating any increased impacts to the downstream system . . Please proceed to review this Drainage Adjustment Request. Thank you for your consideration. Daniel K. Balmelli, P .E. DKB/cb enc: As noted 00: .

RE: L02POO II -Hamilton Place Dear Ms. Claussen: K.C. D.D.E.S. I would like to have the following comments submitted for the above reference Land-Use Application. In the Notice of Application, it states "Development regulations to be used for project mitigation, .. .including sensitive area regulations, 1993 King County Road Standards, etc." The year 2002 is almost over. My husband and I were involved in a SEPA appeal hearing for the Stoneridge Development. In that hearing KC Roads stated that they were now using the 1997 Road Standards. I believe that the KC Road Standards have been upgraded since 1993. As such, the use of the most current Road Standards should be used for determining mitigation for this proposed development. Also, noted in the Notice of Application is the Date Determined Complete: July 2, 2002. On June II, 2002, the King County Council adopted new traffic currency standards for King County Roads. This proposed development is now located with the "red" zone, which means no new development can occur until the County bring the Roads up to code. Based upon the when the application was completed and when the County Council declared this area "red", in my opinion, any work on this proposed development cannot go continue. Thank you for allowing me to make comments on this proposed development. Exhibit No. 1:f"'R.

As of March 9, 2003, I have not received any information from DOES regarding the above referenced plat. How can I talk about the SEPA conditions DOES proposes if one isn't given a copy of the recommendations? Even if I had wanted to appeal the SEPA recommendations that DOES is recommending, the deadline for such an appeal has come and gone. Maybe this hearing should be moved back so that DOES can do things legally in regards to notifying parties of interest of the SEPA recommendations.

See the King County proposed development maps submitted by land developer companies. General Comments: I. First let me say thank you for coming out of retirement to hear this case. It is a landmark case for our area, since outside developers and land companies are vying to develop 5 substantial acreage plots, 3 within 1,600 feet of my home, and 2 within 200 and 400 feet of my home. (See the maps presented by Gwendolyn High and Marsha.) How do we know it's a landmark case: Page 14, last paragraph, of the report says liThe sewer and road improvements for this rezone/plat are necessary to make this first C stage of urban conversion successful, and will provide an infrastructure foundation for the further development of ,other properties consistent with the R-4 designation." P.S. Thank you for the interception and questioning you did from time to time in difficult areas. 2. Secondly, let me say thank you for extending the hearing so that the current family residential land owners could be heard adequately. It is my hope that in the future there will be enough time allowed for the resident citizens land owners to cross examine the developers and DDES as they have been allowed to do to us. 3. If the R6 or greater zoning for these two plots is placed in the middle of our R4 zoning, the impact of this will open the way for the other 3 acreage plots to be re-zoned as R6 or above which would have substantial adverse effects. The safety of the current residents and the environment of this area, which contains Class II Wetlands, cannot support such a great number of homes in such a confined area. a. This would conservatively add 132 homes on approximately 22 acres. (Evendell File plat at R-6 zoning would be Evende1l90 homes on both plots, plus 27 and 15 on the other proposed developments). b. In comparison, at R-4 the density would be 72 homes total as follows: the Evendell plot at 44 on one plot, plus 18 and 10 for the other two proposed plots. c. Again this does not even include the 5th plot development which is planned. Exhibit No, _\1-9...1..-___ _ Item No. ~!2 ~~t) \,\ Received ~ -) \-,,:, , King County Hearing Examiner *4.

Conduct of the hearing: Even though you cautioned all to speak up, the microphones, not being both recording and speaking did not enable us to hear the DDES staff, who ,most of the time had their backs either fully turned to us or partially turned when testifying.

(The species are contained in the attachment to my initial submittal presented at the DDES hearing on the 61h of March.) 3 a. PAGE ONE: ZONING AND PROPERTY RIGHTS: paragraph two cites a 46 lot plat based on the existing R-4 zoning on the east 11.46 acres. However, the description below at "Acreage RezonelPlat" lists 13 acres with a density of 5.6 dwellings per acre with 7.4 dwellings per net acre. These statistics seem to stretch 4 single family dwellings to an acre to 7 an acre and are incongruous. The numbers have been bandied about throughout. Further in to the document 15 acres is the amount listed. On attachment 4 page one is shown R-6 zoning and 4-12 units per acre; on attachment 4, page 2 is shown a 12.43 acre site with 6 houses per acre, for 74.58 dwelling units, and residential subdivision and townhouses developed at a density of 8 units or less per acre, number of proposed units 70; on attachment 4, page 3, 48.17 minimum dwelling units are required; on attachment 4, page 4, is a maximum density of 12.43 acres. ACTION: I CALL THIS TO YOUR ATTENTION AND I WOULD LIKE AN EXPLANATION OF SO MANY VARIANCES. It is verv confusing and opens the wav for misinterpretation. On page 13 of the report at Rezone, 2. Paragraph one states 5.6 dwellings are appropriate per acre. Page 13 determines that the properties now owned bv resident families "have no! developed to their highest potential use and density". JUST WHO IS MAKING A DETERMINATION THAT BY LIVING ON MY ONE ACRE, OR ON FIVE ACRES, WE ARE IN CONFLICT WITH THE HIGHEST POTENTIAL USE AND DENSITY AS OTHERS who are not the property owners SEE IT. WE EACH OWN THESE PIECES OF LAND BY LAW. NO ONE HAS THE RIGHT TO TELL ANY OTHER OWNER OR ME WHAT THE BEST USE OF THAT LAND IS NOR TO SET UP ORDNANCES IN SUCH A WAY THAT THEY TAKE AWAY OUR RIGHTS AS PROPERTY OWNERS. b. On page one and in appendix 8, the Renton School District is listed. It is the Issaquah School District. Yes I see where the Issaquah .transportation officer's card business card appears on appendix 8, but page one remains unchanged, and Karen Scharer, DDES, made an administrative error when she said that the East side of 158th Ave. S.E. goes to Issaquah and the West side to Renton. In fact, both go the Issaquah. ACTION: Please ensure the testimony data is corrected. c. Page 2. "Community Plan: Newcastle". This is not the Newcastle conununity, which ends at the May Valley Road substantially north of here. It is the Four Creeks Unincorporated area, bounded by Briarwood, Coalfield, and Lake Kathleen, with May Valley on the North and East flanks. d. Page 2, C 1. • Question: What pipeline are we talking about? We are unaware of any existing or planned. e. Page 2, D. Threshold Determination of Environmental Significance: All of the submittals to DDES by a large number of the current residents in April 2002 requested an environmental impact study (EIS) be done. As residents we find the mitigated determination of non-significance (MDNS) rather surprising in that we presented evidence to the contrary on animal, reptile (newts, snakes, lizards), bug, insect, flora, and fauna, as well as surface water Class II Wetlands, the presence of substantial ponds in the area (two private on 158"' Ave SE, and a large one the size ofa small lake on I 64th Ave. SE), and other drainage issues. ACTION: We request again that an EIS be required bv the Cedar Basin Steward and other appropriate officials from the King County Surface Water and Land Management offices, of the Department of Natural and Land Resources, King Street Station, 201 South Jackson Street, Suite 700, Seattle, W A 98104, prior to rezoning. An EIS was also requested on page 5 of the resident survey submitted by Gwendolyn High in April or so of 2002 regarding species with sensitive classifications. I attached this April 2002 request to my initial letter presented at the DDES hearing on March 6, 2003. f. Page 2, D, MDNS: Notification was not received by the current residents on the mailing list that I contacted, of the 21 days to appeal the MDNS. g. Page 2, D. The statement is made in the MDNS "other sources of substantive authority may exist but are not expressly listed." • Question: If they have substantive authority, why aren't they listed. h. Page 3, E, Agencies Contacted: . 4 • Question: Why were four State agencies contacted, but not other King County Agencies. At the very least King County Surface Water and Land Management ofthe Department of Natural Resources (address listed at e.), and the appropriate King County offices for Ecology, Fish and Wildlife, and Transportation should have been contacted, apart from DDES for analysis input. • ACTION: Please require that the other King County offices are coordinated with and included in the analysis requirements for rezoning and not just DDES. i. Page 4, F. Natural Environment: We ask you to consider in your determination: (I) A 20-foot difference in height is substantial. (2) The soil survey was made 30 years ago. Substantial changes in tree growth, etc. have occurred. (3) 200 square feet of wetland to be filled means permanent loss. My Iymnologist Civil Engineer daughter who has lived here over 30 years and worked for King County as a lake manager for six, says that the wetland will never recover. (4) Almost 7,000 (6,989) Square Feet of wetland impact is substantial. (5) Paragraphs P3, Par 3, paragraph 4, 5, and 6. ACTION: The analysis items at page 4, F. should be done by the King County Surface Water and Land Management office of the Department of Natural Resources, listed earlier at "e." (6) Paragraph 6. Wildlife: The flat statement "there was no specific information provided in the citizen's documentation to indicate the presence of nesting sites on the proposal property for any protected species" is inaccurate. Submittals were made as required, in time for the deadline. j. Page 5, G. Neighborhood Characteristics: (I) Paragraph 1. As stated earlier this is the Four Creeks Area, not the Renton Highlands, which is a distinct community within the City of Renton and has been for 60 years. (2) Paragraph 2 and paragraph 6 refer to a rezone within the Renton City Limits. ACTION: Please investigate and note that and R-S, R-6 or R-8 zone within the Renton City Limits is not the same as an R-S, R-6 or R-8 zone outside the Renton City Limits. (3) Paragraph 2. The sewers for Highland Estates are over a mile away. (4) Paragraph 4. Please spell out what.9 d.u. per acre means. (5) Paragraph 5. Time for submittal of the applications for three other plats IS partially known. My neighbor just received notice ofa hearing on March 18,2003, for one of them, prior to the March 6, 2003, DDES hearing .. (6) Paragaph H. 1. QUESTION: If it is R-4 than how can density be accepted at 5.6 d.u.'s? until the re-zoning is approved? (7) Paragraph H. 2. The 46-lot plat is more than 4 single family dwellings to II acres. No accuracy here. k. Pages 5 and 6 regarding the "public loop". One access entrance into the entire development at 70 plus homes traps homeowners and is not safe should a major disaster created by high winds or fire occur and all be trying to exit at the same time and find emergency vehicles or simply mass exodus blocks the way. I. Page 6. Drainage: Drainage is referred to in several places throughout the document, the largest sections being on page 3, page 18, page 20, and 21 of the DDES report. There are confusions and inequities which are important issues prior to the type of permit being granted. During presentations on March 6, 2003, at the public hearing there were many regarding sewers and drainage. 5 Mr. Romano's and the DDES presentations were confusing and alluded that sewers and storm ponds would alleviate the ground water problems in the area, while protecting the Wetlands and provide recreational space. ACTION: We request that DDES present Gwendolyn High, our chosen representative, with reports from King County Surface Water and Land Management, and from the Cedar River Basin Steward regarding the following issues: Note: My daughter is a professionallymnologist by trade and a civil engineer. She lived at 13125 158th Ave. SE. for over 30 years. For 6 years, ending in June 2001, when she married and left the immediate area, she worked for King County Surface Water and Land Management (KCSWLM). She was a specialist and lake manager for numerous lakes and streams in King County. She is especially concerned about the sewer, storm pond, and storm drainage systems, and that KCSWLM be included as authorities with substantive shareholder rights in this rezone. a. Storm Ponds: (I) Until storm pond statistics from the King County Surface Water and Land Management offices and the Cedar River Basin Steward are obtained for a comparison on how well the storm ponds (detention as they are called in this document) actually function in this area and surrounding areas of like land during the wet season and over time, and .are presented for public access, the reports by DDES and the Haozous Engineering, Inc., are subject to subjective misinterpretation and conjecture. . (2) As landowners owners we feel we are subject to being easily misled without accurate studies and facts from these other authoritative and substantial shareholders analyses being required and incorporated into the DDES findings. b. Sewers and Storm Drains: The issues of sewers and ground water handling as presented were confusing. Homeowners were led to believe by the language used by both DDES and the developer and his representatives that sewer installation would take care of part of the surface water issues. There was barely any mention of storm drains in the hearing presentation itself, if they were mentioned at all. In fact this is still a significant issue which needs to be clarified and resolved before ANY approval is giving to the developers who seek to expand the zoning beyond R4. (I) Sewers are specifically designed so that storm drain surface water cannot penetrate them. This is because penetration from stonn drain surface water will compromise the entire sewer system and leads to overflow and collapse (2) On page 3 at A. East Drainage Basin, you do not mention who hired Haozous Engineering to do the level 3 Downstream Drainage Analysis by Haozous Engineering. There is no provision for upstream, which evacuation of downstream will surely impact. (In fact on attachment 9 this is alluded to, page 2 of 3, at the top of the page at "4." 6 What King County Surface Water and Land Management authorities has DDES submitted this Analysis to. If Haozous Engineering was hired by the developer, then the county has a responsibility to ensure through County authorities that the analysis is accurate and unbiased when it affects county residents. (3) 1,700 ft downstream is an insignificant area when talking about the affect or non- affect on the larger area of this neighborhood which such installations will have. Therefore, using it as a justification for applying this to the greater neighborhood, is in question. (4) On page 3 at B. West Drainage Basin DOES quoted KCSW.QM Core requirement 2. How old is the manual. Has it been affected by any modifications or changes? Where is a current and comparative study from the KCSW and LM? Furthermore DOES did not identify the streets as they did on page 3 at A. East Drainage Basin. (5) Note on page 16 7.c. that there is no approved permanent storm drain outlet # yet on file with ODES and/or the King County Department of Transportation. And, Istill wonder at "e" how you can use a drainage tract for required recreation space. (6) On Attachment 9, page 2 of3, at the top "4." "As a result, controlled outflows from the western area will be released FARTHER UPSTREAM IN THE DITCH SYSTEM OF 156TH AVE. SE." In the analysis, DOES states that the culverts are undersized. It is my understanding that the Cedar River Basin Steward has a legitimate concern about this fall out. m. Page 6. I. 2: Transport Plans: "Most trips will be via 156th Ave. SE." That is pure conjecture. You cannot predict what drivers will do. We get heavy overflow from 160th across 132nd and up 158th, now and opening 136th with one egress to the development is sure to increase traffic up 158th substantially. At 1.3. The report states "700 vehicle trips a day will be generated" leaving the single egress under the developer's plan for R-6 zoning. Even at zoning for R-4, those residents living on 158th believe these cars will go in a straight line up 158th. n. Page 7, 4. Adequacy of Arterial Roads: Relies heavily on modifying traffic standards by allowing a payoff Mitigation Payment System. Fact: As residents who will suffer over the six years mentioned, we find this most curious and again a way of taking an existing ordnance and moving it into the gray area rather than black and white to get around or sfall the requirement, which gives a break to the developer and not the existing residents. o. Page 7, Public Services J. I. Does not apply as stated since it refers to the Renton School District and School Board and should be from the Issaquah School Board and District. ACTION: Please see that this is corrected. p. Page 7, 2. , and page 19 at items 18. and 19. Parks and Recreation Space. (1) We understand the county is selling the one parcel that would have benefited all of the immediate neighborhood (adjacent to 160th). (2) The county is not in a position to guarantee parks for us since they are closing so many due to funding. (3) Later in the DOES document it states that the homeowners will be responsible for upkeep of the "park" in the Evendell plots. The neighborhood at large will not be comfortable going to a park inside the Evendell development, and with 70 house on 11 acres, plus a pump station, and a storm pond, the park will be insufficient to serve the entire neighborhood surrounding the Evendell plot. ACTION NEEDED ON A FIRE SAFETY ISSUE: Sandwiched in here ON PAGE 8, J.3 is water for fire prevention. Documented FACT: When my neighbors and I cannot take showers in the summer because of low water pressure, how is the fire protection going to be maintained? r ~- q. Page S Comprehensive and Community Plan: (I) As I established in the hearing on March 6th , the KC Comprehensive Plan with Land Use Map designating this area at 4-12 dwellings per acre, does not override the R4 zoning in affect in this area. ACTION: Therefore this statement is irrelevant, misleading, and should be removed. 7 (2) U-114 and U-llS appear to be in conflict with U-120 which states, KING COUNTY SHALL NOT APPROVE PROPOSED ZONING CHANGES TO INCREASE DENSITY WITHIN THE URGAN AREA UNLESS: A. THE DEVELOPMENT WILL BE COMPATIBLE WITH THE CHARACTER AND SCALE OF THE SURROUNDING NEIGHBORHOOD." Going on below to r.: r. Page 9. a. b. c. e., and on page II, especially the last two paragraphs: Regarding the neighborhood identity referred to here, as residents with knowledge of the neighborhood we note that THE "NEIGHBORHOOD" IDENTITY IS USED V ARIOUSL Y by DDES and the Developer TO INDICATE THE IMEMDIATE AREA BOUNDED BY 160TH, SE 12STH, SE 13STH, AND 156TH IN UNCORPORA TED KING COUNTY AND THEN IS STRECHED INTO THE CITY OF RENTON AREA OR FUTURE PLANS, WHEN IT SUITS THE PURPOSE OF THE DDES AND THE DEVELOPER. IF WE WERE TO FOLLOW THE LINE OF LOGIC THAT RENTON'S PLANS SHOULD OVERRIDE THE PLANS OF THE RESIDENTS OF UNINCORPORATED KING COUNTY BECAUSE THE LATER'S PLANS MIGHT NOT FIT IN TO THE FUTURE ANNEXATION PLANS OF CITIES, THEN ALL LAW FOR THE PROTECTION OF THE UNINCORPORATED COUNTY RESIDENTS WOULD BE OF NO EFFECT, AND WE WOULD BE AT THE MERCY OF THE CITY. FACT: THE RESIDENTS OF UNINCORPORATED KING COUNTY E ARE NOT PART OF THE CITY OF RENTON, YET, AND UNTIL WE ARE, RENTON CITY COVENANTS AND ZONINGS DO NOTAPPLY. THEREFORE AT (9.d) The DDES comment that the Evendell plat plan does not exceed the City of Renton Comprehensive Plan for 8 dwellings per acre, has no bearing on applications in unincorporated King County. I repeat, City of Renton zoning is not the same as unincorporated King County ACTION: THESE COMMENTS in section U120 AS RELATED TO THE CITY OF RENTON. SHOULD BE REMOVED AND NOT APPLY IN TIfE DECISION TO GRANT A REZONE IN UNINCORPORATED KING COUNTY. s. Page 10: Charts; (I) Footage statistics developers and DDES are using on page 10 of the DDES report are truly miniscule when you look at the area to be served and make the chart totally irrelevant. t. Page 12 KCC20.24.195 at Additional examiner findings -preliminary plats. A. "Appropriate provisions are made for the public safety. and general welfare and for such open spaces ... , Etc,lI Please consider these requirements carefully and apply them to your decision. There will be no open spaces when the developers get through. No safe roads to walk on except in Evendell itself. The rest of us are asked to put up with unsafe road conditions for a minimum of6 years. We who have lived here 30 years will not have access to parks contained in private neighborhoods. Our children will have to endure 700 more cars a day without benefit of sidewalks or wider streets because once they leave the egress to Evendell, guess what, they go straight past my house. u. Page 13 SEPA and Rezone. (I) MDNS, which applies to SEPA is addressed on page 3 at items e, f, and g of this letter. (2) Rezone and property owners rights are addressed on page 2, 8 a of this letter. (3) The maps shown by the developer of how they will develop properties and seek permits to do so are in question. A minimum of 4 large tract property owners stood up in the meeting and said they do not plan to sell and they find it unnerving that the DDES or anyone else can give permits, or design overlap, ahead of the fact to developers. 8 w. Attachment 61 We as property owners and resident citizens find it questionable ethics and a breach of property owners rights and wonder how it will stand in a court of law, for the City of Renton, to make the statement that "In order to receive sewer service from the City, the plat must also develop as detached single family and the property owner(s) will be required to execute a covenant to annex form. Will future buyers be presented with this requiremerit before they have already sold their homes and are ready to sign the final papers to buy in this area so they can change their minds. or will they not find that they must sign away their voting rights until the day they sign their final papers. have already sold their other house and are in effect forced to sign. In closing: THERE APPEAR TO BE SERIOUS LEGAL ISSUES HERE REGARDING AN ABRIDGEMENT OF PERSONAL RIGHT, NOT JUST AS PROPERTY OWNERS, BUT AS VOTERS, We wonder if this will be construed by the courts and the public that the City of Renton, the County, and the land developers appear to be in collusion. Especially as it has been the factual experience of many residents that, when inquiring about who has jurisdiction and how can we get fair and just treatment, the buck gets passed in this area from one governmental authority to the other and back again, leaving us high and dry. And then we get a document like this full of mitigations which seem to support that conclusion. So many people worked on this report at DOES, and with the confusion they must experience in dealing with so many laws and regulations, and probably being short funded and short staffed, I wonder if anyone in a higher position checked it to see to it that each one's work agreed with the others. There are so many inconsistencies in this document that I don't see ethically and in good conscience how you can award the rezone to R-5 or higher. Even at R-4, the inconsistencies will need to be addressed before granting any current or future permits and zoning standards to the developer(s) at all. Thank you for the time and effort you will be putting into your decision. Respectfully submitted, Michael Rae Cooke 13125 158h Ave. SE.

We have reviewed your March 9,2004 submittal and with the following conditions, approve it as submitted: ' 1. The equipment (play structures, benches, picnic table, etc.) shall meet at a minimum, Consumer Product Safety Standards and be appropriately anchored. 2. Walkways to the play areas (play structure, sport court, etc.) shall be constructed of a material arid grade that is Americans with Disabilities Act (ADA) accessible. 3. Landscaping located on the south side of the fence shall be relocated internal to the recreation tract (Tract A). 4. Street trees and drainage control(s) associated with the recreation tract shall be reviewed with the engineering plans. 5. Revisions shall be incorporated into the final engineering plans, The landscaping and recreation space improvements (Le. play structures) must be instalied and inspected or a performance bond posted, prior to plat recording. The amount of the performance bond has been established at $47,711.00. This includes landscaping, equipment, surfacing materials, etc. The bond amount includes a thirty-percent contingency, Note, this approval and bond quantity amount does not include street trees, wetland details/signage or landscaping associated with the drainage facilities. This will be reviewed in conjunction with the engineering plans. . An inspection fee is also due prior to recording. This fee covers the cost of an installation inspection and a maintenance inspection. The amount of the inspection deposit will be determined by the Land Use Inspection Section (LUIS). If a performance financialguarantee is posted, the improvements must be installed within two year's from the date of recording.

The project is also located between 158 th Avenue Southeast and 160th Avenue Southeast near the "T" intersection of Southeast 134th Street. The project includes construction of a new east/west public access road extending from 158th Avenue Southeast to 160th Avenue Southeast along with half street improvements along the frontage of both streets. The enclosed Vicinity Map, Preliminary Plat Map, and Preliminary Engineering Design Plans indicate the location of the project site and surrounding conditions. The existing topography of the site contains slopes ranging from approximately two percent to five percent. The site generally slopes from the northeast to the southwest sheet flowing through a small wetland area located at the southwest comer of the site and then into an open drainage ditch located along the east side of 158 th Avenue Southeast where it continues in a southerly direction eventually discharging into the Cedar River. Existing vegetation on the site consists of mostly pasture grass and a few scattered ornamental trees on the northerly half of the site and more dense trees and brush on the southerly portion of the site. The site currently contains one existing residential home, an existing out building, and small shed which will all be removed as part of the development of the residential project. The King County SCS Soils Survey Maps indicate the existing soils underlying the site as Alderwood Gravelly Sandy Loan (AgC-Hydrologic Soil Group C). See Exhibit F. • • UPSTREAM DRAINAGE ANALYSIS From a review of the City of Renton aerial topographic survey maps, the detailed boundary and topographic Survey prepared for the project and field inspection, it was confirmed that the site receives off-site tributary runoff from approximately two acres of property located just north of the project site between Southeast 13200 Street and the northerly boundary of the project site. The upstream tributary area contains approximately six single family residential homes which appears to sheet flow surface runoff across the project site in a northeast to southwest direction. Property to the east and west of the project site are bounded by 160 th Avenue Southeast and 1 58 th Avenue Southeast which contain open ditch drainage systems. Property located south of the project site is lower in elevation and drains in a southerly direction away from the site. Please refer to the Combined UpstreamlDownstream Drainage Area Map showing the upstream drainage basin and off-site tributary area. • • ON-SITE DRAINAGE ANALYSIS The proposed storm drainage system for the project will consist of catch basins and underground storm pipe, tightline roof drain connections and a combined open vegetated wetl detention pond located near the southwest comer of the property. Storm~ater runoff from the new public access road extending from 15811t Avenue Southeast to 1601lt Avenue Southeast will be collected by catch basins and underground storm pipe and conveyed in a westerly direction discharging into the open combined wetldetention pond for detention and water quality treatment prior to discharging off site into the existing open ditch system along 15811t Avenue Southeast. Surface water runoff from lots 12 through IS and lots 17 through 22 will be collected by private storm lines located along the southerly, low end of the lots to collect surface runoff from building roof drains, driveways, and landscape areas and convey the surface runoff to the stormwater facility. According to King Country, the project site is located within an area which requires basic water quality treatment and level IT flow control. All stormwater runoff from the project site including the new public roadway, and lot drainage will discharge into the proposed combined open vegetated wetldetention pond located in Tract "B" for stormwater detention and treatment. From here, stormwater will discharge through the existing wetland and proposed 25-foot buffer located in proposed Tract "D" via a dispersaI system and then discharge into the open drainage ditch located along the east side of IS8 11t Avenue Southeast. ,--------------------• EXHIBIT "A" VICINITY MAP • • • SE 124TH w ;1 ~I V> ". < iE iE iE ~ 0 ~ ~ ~ -- ~ SE l' 1<800 SITE PARI( S~T", '~~ ~ <' :,; ~ I /_ '-ll!.ST~ I S[ 132ND ST _ "c, ~, RD 24 C fl4R ........ _ .......... , ...

Finalized Drainage Studies None known. Basin Reconnaissance Summary Report The site is located within the Orting Hills Sub Basin of the Cedar River Watershed according to the King Country Department of Natural Resources. Critical Drainage Area Maps The site is not located within a Critical Drainage Area according to King County. Floodplain and F100dway FEMA Maps Based on a review of the FEMA JOO-year Floodplain Maps, the site is not located within a 100-year floodplain. Please refer to Exhibit "r' (FEMA Floodplain Map). Other OtT-site Analysis Reports A copy of the US Department of Agriculture Soils Conservation Map is included in the report as Exhibit F. The soils within the project site are identified as Alderwood Gravelly Sandy Loam (AgC, 6 to 15 percent). Sensitive Area Folios From a review of the King County Sensitive Area Maps the site is not located within any sensitive areas for Erosion Control Hazard, Seismic Hazard, Landslide Hazard, or Streams and Flood Hazard areas. • • Road Drainage Problems None identified. United States Department of Agriculture King County Soils Maps According to the US Department of Agriculture King Country Soils Maps, existing soils underlying the site consist of A1derwood Gravelly Sandy Loam (AgC, 6 to 15 percent). Wetland Inventory Maps Based on a review of the King County Wetland Inventory Maps, the site contains an area of potential wetlands. A wetland delineation and reconnaissance report prepared for the project has confirmed that the site does contain a small wetland area located at the southwest comer of the project site.

WETLAND EVALUATION SUMMARY: Data was collected in the five categories shown below. Within each category the data was evaluated to produce numerical values. Composite values for each category were produced in order to compare each wetland to other wetlands in its sub-basin and in King County. The result of that comparison we. a percentile rank. The percentile is expressed on a scale of one hundred and indicates the percent of wetlands that scored equal to or below that particular site. For example, a percentile rank of 80 under sub~asin means that the wetJand scored eQUal to or bettar than 80 percent of all sites within the sub-basin for that evaluation category. NOTE: The percentile ranks are valid only within the individual evaluation category and are intended solely for reference and comparison. Evaluation Category Hydrology: runoff storage potential, water quality, potential for minimizing damage in downstream areas Biology: quality of habitat, abundance and diversity of plant and animal species Visual: diversity and contrast of wetland and surrounding vegetation, surrounding landforms Cultural: types of access, prOXimity to schools/institutions, overall environmental quality Economic: presence of agriculture/peat extraction, anadromous or game fish, game birds or mammals of commercial value WETLAND RATING: Rank (by percentile) Sub·basin County·wide 71 85 64 78 92 76 14 42 35 51 Each wetland was assigned one of three possible wetland ratings. The wetland ratings were determined by exanining the scores of selected inventory tasks, specific data or percentile ranks for individual evaluation categories. The criteria used to assign the wetland ratings are described in the Introduction. For each rating 8 number of specific gJidelines for new development in or adjacent to wetlands were prepared. The guidelines are intended to assist in carrying out King County's Sensitive Areas Ordinance and other wetland policies. They are included in a separate report titled "Guidelines for King County Wetlands". Wetland Rating: 1 (b , C) • • • EXHIBIT "I" BASIN RECONNAISSANCE SUMMARY REPORT (NOT APPLICABLE) • TASK 3 FIELD INSPECTION • I I 1---------------------------------------------------------- • • 3.3 Severe Flooding Problems (Type 3) Severe flooding problems can be caused by co11Veyance system overflows or the elevated water surfaces of ponds, lakes, wetlands, or closed depressions. Severe flooding problems are identified as follows: • Flooding of afinished area of a habitable bUildingfor runoff events less than or equal to a JOO-year event. Examples include flooding of finished floors of homes and commercial or industrial buildings. Flooding and electricallheating systems in components of the crawl space or garage of a home. Such problems are referred to a "severe building flooding problems. " • Flooding over all lanes of a roadway or severely impacting a sole access driveway for runoff events less than or equal to the JOO-year event. Such problems are referred to as "severe roadway flooding problems. " From a review of the King Country drainage complaints, and from field inspection, there were no identified drainage problems within the downstream drainage system which could be identified as "severe building flooding problems" or "severe roadway flooding problems." As required by the 1998 King County Drainage Manual for projects within this drainage basin, the proposed project will provide Basic Water Quality Treatment and Level II Flow Control as part of the design of the stormwater management system to help reduce the potential for any significant impacts to the downstream drainage system within the Cedar River Watershed area. • • TASK 3 -FIELD INSPECTION During the on-site field inspection, there were no significant erosion or capacity problems observed in the downstream. There were several minor erosion and conveyance system nuisance problems identified in some of the open ditches and from a review of the resource material. Based on a review of the applicable drainage complaints located in the downstream drainage course, there does not appear to be any current existing significant restrictions or capacity problems in the existing downstream system. The field reconnaissance did not identifY any potential constrictions or capacity problems in the downstream system. 3.1 Conveyance System Nuissance Problems (Type I) Conveyance system nuisance problems, in general are defined as any existing or predicted flooding or erosion that does not constitute a severe flooding or erosion problem. Conveyance system nuisance problems are identified as flooding or erosion that results in the overflow of the constructive conveyance system for runoff events less than or equal to a ten year event. Examples include indignation of a shoulder or a lane of a roadway, overflows collecting in a yards or 'pastures, shallow flows across driveways, minor flooding in crawl spaces or unheated garages/outbuildings and minor erosion. From a review of the available drainage complaints, there appears to be only one potential conveyance system nuisance problem identified under drainage complaint No. 91-1000 which identified a maple tree which was restricting drainage within the existing open drainage ditch downstream of the project site. 3.2 Severe Erosion Problems (Type 2) Severe erosion problems are defined as downstream channels, revines, or slopes with evidence of or potential for erosion/incision, sufficient to pose a sedimentation hazard to downstream conveyance systems or propose a landslide hazard by undercutting adjacent slopes. Severe erosion problems do not include roadway or minor ditch erosion. Based on field inspection and review of the applicable King County Drainage Complaints, there was no identified or evidence of potential severe erosion problems within the downstream conveyance system within the portion of the system analyzed as part of this project . ... -_. ------------------------------ • • EXHIBIT "J" OFF-SITE ANALYSIS DRAINAGE SYSTEM TABLE Basin: Symbol OFF-SITE ANALYSIS DRAINAGE SYSTEM TABLE Surface Water Design Manual, Core Requirement #2 {;.. &£I/h? _ RIlL m Subbasin Name: 0 RTf" /b JrlkkS Subbasin Number: Drainage Comporient .

This runoff will be intercepted by a drainage swale which will be constructed along the northerly property line and conveyed west to the existing open ditch system within 158 111 Avenue Southeast. After stormwater runoff from the project site discharges into the existing open drainage ditch (LI) storm flows begin flowing to the south and discharge through a series of concrete culverts (L2, 3, & 4) over a distance of approximately 650 feet until entering an open eastlwest ditch (L6) which drains to the east for approximately 630 feet where it discharges into the existing roadside ditch along the west side of 160111 Avenue Southeast (L 7) and continues in a southerly direction for approximately 750 feet. Drainage then discharges through a 12-Inch culvert (L8) and continues in a southerly direction through the open roadside ditch (L9) where it discharges through another 12-inch driveway culvert (L I 0) and continues for approximately 200 lineal feet in the roadside ditch. At this point, stormwater is conveyed to the east side of 160111 Avenue Southeast via a 12-inch concrete culvert (L II) and continues in a southerly direction for a short length until discharging through a 24-inch cmp culvert (L12) with a pinched end. From this point, drainage continues in a southerly direction along the roadside ditch (Li3) for approximately ISO feet and then discharges through an 18-inch diameter polyethylene culvert (L14). According to King County records, drainage complaint No. 97-0423 was reported near this location. The drainage complaint was apparently related to overflow of the roadside ditch but was not available in King County records. From this point, stormwater continues in a southerly direction along the roadside ditch (LIS) for approximately ISO feet to a point where drainage then flows in an easterly direction away from 160111 Avenue Southeast through a relatively flat drainage swale heavily vegetated with trees and brush. The swale contains areas of ponding water (L 16) and then becomes more defined. The drainage swale then discharges through a 12-inch culvert (L17) and then through another 12-inch driveway culvert (L18) and then continues in a east to southeasterly direction through an open swale (L 19). The drainage swale continues along the north edge of an existing residential development, a portion of which has been reinforced with concrete blocks until entering an 18-inch diameter culvert with a trash rack and concrete headwall (L20). Storm flows continue in an easterly direction until reaching the unopened right-of-way along 16200 Avenue Southeast (L21) and then turns and continues in a southerly direction in an open channel (L22). From here, the drainage channel continues in a southerly direction for approximately 600 feet down the hill until reaching southeast 144111 Street. According to King County records, drainage complaint No. 97-0206 was reported at location (L20). According to the complaint, the resident has had drainage problems from runoff in the channel along the north side of his property which may have affected his septic system. It appears that some improvements have been completed along the drainage channd. • • From field inspection of the existing downstream drainage system, there were no observed significant erosion or capacity problems. It should also be noted that portions of the roadside drainage ditch along both sides 160th Avenue Southeast both upstream and downstream of the project site have been recently cleaned and regraded. Straw wraps have also been placed within the section of the roadside ditches which were recently cleaned to help prevent erosion while the ditches restablize. REVIEW OF DRAINAGE COMPLAINTS IN DOWNSTREAM DRAINAGE SYSTEM Copies of applicable drainage complaints within the downstream drainage system were obtained from the King County Water and Land Resource Division. Copies of tIle drainage complaints are included in Exhibit "K" Drainage Complaints. The following is a description of each of the drainage complaints. Complaint No. 89-0867 Date: 1989 Property Owner: Address: 13902 160 th Avenue Southeast Drainage complaint not available. Complaint No. 91-1000 Date: 9/17191 Property Owner: David Nyblom Address: Southeast 136 th Street, between 156th Avenue Southeast and 160th Avenue Southeast This complaint is located within the downstream drainage system of the project site approximately 650 feet south of the project within the open drainage ditch listed as (L6 in the downstream drainage analysis). This complaint indicates that a large maple tree located midway between the drainage ditch causes drainage to overflow the ditch. Complaint No. 95-0107 Date: 2/01195 Property Owner: Steve Kohr Address: 15641 Southeast 138 th Place This drainage complaint indicates a possibility of a broken culvert at the entrance of the Southeast 138th Place cul-de-sac. This drainage complaint is not located within the sub basin of the project site's downstream drainage system. I • Complaint No. 97-0206 Date: 1/10/97 Property Owner: Don Gragg Address: 16046 Southeast 14200 Place • This drainage complaint indicates that off-site water was diverted from 14200 Place to the adjacent 5-acre tract and floods his property. Mr. Gragg indicates that he usually can prevent the flooding by maintaining the diversion, but was out of town during a heavy storm event, and therefore, his property including his drain field area was flooded. It appears that some additional improvements have been completed within the drainage system since the time of this drainage complaint to reduce or eliminate the flooding problem. Complaint No. 97-0423 Date: 1997 Property Owner: Address: 14028 160 th Avenue Southeast Although this drainage complaint was not available, it appears that from a review of the drainage complaint information identified in the Avendale Plat Preliminary T echnica1 Information Report, a restriction in the existing roadside ditch along 160th Avenue Southeast near the existing 18-inch PE storm culvert identified as (L14) in the downstream drainage analysis caused overflow of the ditch. Complaint No. 98-0202 Date: 3119/97 Property Owner: Pam Huff Address: 14312 160th Avenue Southeast This complaint indicates that the neighbor on the north side of the property filled a low area and then paved it resulting in runoff discharging onto the Huff property. This property is not located directly within the sub basin of the downstream drainage system of the project site.

Balmelli, P .E. Barghausen Consulting Engineers, Inc. 18215 _nnd Avenue South Kent, W A 98032 RE: Hamilton Place Subdivision KCSWDM Adjustment Request (Pile No. L02V0098) Dear Applicant and Engineer: The Land Use Services Division, Engineering Review Section, has completed review of the adjustment request for the Hamilton Place subdivision. You are requesting approval for an adjustment from the 1998 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 Hamilton Place subdivision is located between 158 th and 160 th Avenues SE at SE 133 rd Street. The 23 lot, 4.3 acre, proposed Hamilton Place subdivision is filed under Land Use Services Division (LUSD) file number L02POOII. 2. 'The Hamilton Place subdivision is located in the Orting Hills subbasin of the Lower Cedar River basin. The site is subject to the Level Two flow control and Basic water quality requirements of the 1998 KCSWDM. 3. The rectangular site slopes gently from the northeast to the southwest. Existing sheetflow either migrates to the ditch on the east side of 158 th Avenue SE or crosses the south property line onto the adjacent parcel. Sheetflow that crosses onto the adjacent parcel to the south eventually reaches the ditch on the east side of 158 th Avenue SE and recombines with the rest of the site's flow. The adjacent off-site area to the north, south of SE 132nd Place, supplies upstream tributary flow 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 near the southwest comer of the site. The allowed release would then be dispersed into the adjacent wetland area that drains to the ditch on the east side of 158 th Avenue SE. Nuisance sheetflow across the southern property line onto the adjacent parcel would be significantly reduced. A slight increase in flow will be experienced in approximately 500 feet of the ditch on the east ,--------------- Hamilton Place/L02V0098-- January 9, 2003 Page 2 of3 side of 158'h Avenue SE immediately downstream from the southwest property corrner. The conceptual drainage plan indicates that frontage improvements on 160'h Avenue SE are included. 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 some conveyance restrictions and drainage complaints associated with the natural discharge location. This downstream conveyance path is shared by the Evendell Plat (LOIPOOI6) which was conditioned through SEP A to provide downstream drainage path improvements. Through future plat or SEPA conditions, it is anticipated that Hamilton Place will be contributing to downstream conveyance improvements or providing for Level Three flow control as mitigation. 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 facility draining to the east side of 158'h Avenue SE with the following conditions: 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 Two flow control standard in the 1998 KCSWDM unless modified by plat or SEPA conditions. A 10 to 20 percent volumetric factor of safety must be applied to all storm events requiring detention. 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 off site drainage facilities must be located in a public right-of-way 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. If you have any further questions regarding this KCSWDM adjustment or the design requirements, please contact Mark Bergam at (206) 296-7270. . -------- Hamilton Piace/L02V0098 • January 9, 2003 Page 3 of3 Sincerely, James Sanders, P.E.

SW Renton, WA 98055-1219 October 22, 2002 Re: Request for Adjustment from the King County Surface Water Design Manual Section 1.2.1 for Proposed Hamihon Place Subdivision LUSD File No. L02POO 11 Dear Randal, • KBS III, llC is currently processing a Preliminary Pial Application for a new 23-101 subdivision located between I 58 th Avenue Southeast and 160th Avenue Southeast in King County, Washington. A Level I downstream drainage analysis was prepared for the project and reviewed by King County staff. A plat screening letter was received on July 15, 2002, requesting a drainage adjustment from Core Requirement No. I of the 1998 KCSWDM due to the presence of two existing on-site subbasins which will be combined into one drainage facility as part of the proposed development. After reviewing this information, the existing topographic survey and the downstream drainage area map, it is apparent that although all of the surface water runoff from the project site drains in a northeast to southwest direction into a single downstream drainage basin, a portion of the site's runoff drains across property just south of the project site eventually combining into the downstream drainage system several hundred feet south of the project in the existing condition. Under the developed condition, this surface water runoff will be collected and discbarged to the storm facility located in the southwest comer of the site, thereby, diverting flows from discharging across the property just south of the property. As requested in the July 15,2002, plat screening letter, we are requesting an adjustment from Section 1.2.1 of the 1998 King County Surface Water Design Manual which states "A proposed project that proposes to constnlCt or modify existing drainage facilities must be discharged at the natural location so as to not divert onto or away from the adjacent dowmtream properties." Section 1.4.2 under criteria for granting adjustments states "Adjustments to the requirements in this manual may be granted prOVided that granting the adjustment will achieve the follOWing: .'.'.' ----------------' ---------------------- Mr. Randal Parsons King County • Department of Development and Enviromnental Services • -2-October 22, 2002 a. Produce a compensating or comparable result that is in the public interest. and b. Meet the objectiVes of safety, .fUnction, appearance, and environmental protection and maintainability based on sound engineering judgment. Based on the results of the Levell Downstream Drainage Analysis, we believe that our request for an adjustment to Section 1.2.1 of the drainage manual can be justified. To assist you in processing this drainage adjustment application, the following plans and documentation are enclosed for your review; I. One completed Surface Water Design Manual Requirement/Standards Adjustment Request Fonn 2. Two copies of the Levell Downstream Drainage Analysis completed for the project. 3. Two copies of the Conceptual Stonn and Utility Plan Prepared for the project showing existing site contours and the proposed stonnwater system. 4. Two copies of a portion of the upstrearnldpwnstrearn drainage basin map showing the area to be diverted. 5. Two copies of the adjacent lot ownership map showing the site location and surrounding properties. 6. One check for the current fee for the drainage adjustment request. The topography of the existing site is such that surface water runoff generally drains across the site in a northeast to southwest direction by sheetflow ultimately discharging into a roadside ditch along the east site of 158 th Avenue Southeast. A portion of the site (approximately 1.8 acres) sheetflows across adjacent property to the south prior to discharging into the existing roadside ditch along 158th Avenue Southeast. Under the proposed development plan, all stonnwater runoff from the project site will be collected and conveyed to a wet/detention pond located at the southwest comer of the site, across a small wetland and then into the existing roadside ditch along 15 Sth Avenue Southeast at the southwest comer of the site. Under the developed condition, the portion of the site which sheetflows across the southerly property and into the existing roadside ditch, will be diverted and discharged into the 15Sth Avenue Southeast ditch at the southwest comer of the site. Although all surface water runoff from the proposed project will ultimately discharge to the same downstream drainage channel, a drainage adjustment is required since stonnwater runoff from the developed project will not discharge into the channel at the same location as it does in the undeveloped condition. Mr. Randal Parsons King County • Department of Development and Environmental Services -3- Our justification for the requested adjustment is as follows: • October 22, 2002 a. The proposed adjustment produces a compensatory or comparable result that is in the public interest because of the following: I. The proposed adjustment will not result in an increase of drainage flows to the downstream drainage system by diverting the developed flows further to the west within the existing roadside ditch. The same amount of tributarY area and stormwater flow will discharge into the existing roadside ditch under the proposed developed condition as it does under existing conditions. The only difference will be that the +/-1.8 acres of the site's existing drainage which currently sheettlows across property to the south prior to discharging into the roadside ditch will now enter the existing ditch approximately 300 to 700 feet upstream within the ditch system. 2. The proposal will not increase the peak runoff rate of discharge from the overall project site since all drainage flows from the project will be collected and conveyed to the proposed drainage facility within the same drainage basin which will be designed to provide level II detention prior to discharging off site into the downstream system. 3. The level I downstream drainage analysis attached with this submittal includes a complete description of the upstream and downstream drainage systems for the project. The UpstreamlDownstream Drainage Map included in the submittal shows the area of the project site that will be diverted from the easterly subbasin of the site to the westerly subbasin for detention and treatment prior to discharging into the existing roadside ditch along 158'" Avenue Southeast. b. The proposed adjustment meets the objectives of safety, function, appearance, and environmental protection and maintainability based on sound engineering judgment because ofthe following: The proposed storm drainage detention and water quality treatment system will be designed in accordance with the 1998 King County Surface Water Design Manual for level II flow control and water quality treatment prior to discharging to the downstream drainage system. Since all stormwater runoff from the property will be collected and conveyed to the stormwater detention and water quality treatment facility prior to discharging off site and no increase in drainage flows will occur to the downstream drainage system, no significant impacts to the downstream drainage system will be created as a result of the proposed adjustment. • • Mt. Randal Parsons King County -4-October 22, 2002 Department of Development and Environmental Services 2. The granting of the proposed adjustment by King County would not alter the appearance and maintainability of the proposed drainage system. The portion of the existing site which currently sheetflows across the southerly property, ultimately drains to the same downstream drainage system as the remainder of the site and to the same downstream drainage system under the developed condition. Collecting this portion of runoff and routing it to the southwesterly portion of the site into the proposed stormwater facility will eliminate the need for a separate detention water quality treatment system for the easterly portion of the site. Discharge of storm water flows from the proposed drainage facility will ultimately discharge to the southwest comer of the site into the existing roadside ditch along \S8th Avenue Southeast and continue in a southerly direction similar to existing conditions without creating any increased impacts to the downstream system. Please proceed to review this Drainage Adjustment Request. Thank you for your consideration. Daniel K. Balmelli, P .E.

I did not draft the conditions to allow the option of going to Level 3 Flow Control as mitigation in the easterly subbasin. I am anticipating a condition on Hamilton Place that either the downstream improvements be constructed(by either or both developers), or Hamilton Place could use Level 3 Flow Control. I am thinking, if the improvements are constructed, then Hamilton Place could drop to Level 2 Flow Control. I think it would be beneficial to include a general finding in the proposed drainage variance that downstream improvements or Level 3 Flow Control will be a future condition through the plat process.

Although the Hamilton Place Level One Downstream Report minimized the downstream conveyance issues, and my conditions in the Evendell adjustment did not specifically condition any mitigations, I thought that I would check to see if all was well.
