Superintendent Rieger denied a similar request on August 8, 2014, citing the wetlands studies previously submitted by the purchaser and the fact that those studies and additional information requested by the City of Renton meet the requirements of the City as they work through the review and approval process, Lar. Rieger's reply referred to the purchase and sale agreement that was approved by the School Board on May 22, 2013, noting that the agreement authorizes the purchaser to assess the property's suitability for the intended development, and to take steps to obtain the necessary approvals in compliance with City of Renton ordinances and regulations. The purchaser has proceeded to do so, at considerable expense for the planning and studies required by the City. The studies submitted are subject to review and approval by City staff and by the hearing examiner, who will evaluate them in light of state and local environmental and development standards. The decisions resulting from this process are also subject to appeal, as explained by City staff at the community meeting held on September 4', so that any perceived deficiencies in the existing studies can be appealed as part of the City's review process. In addition to granting certain rights to the purchaser, the purchase and sale agreement formalized the School Board's intent to sell the property, consistent with the School Board's duty to act in the best interest of the entire district. In doing so, the agreement created an obligation for the Board to cooperate with the purchaser as it seeks to obtain the required permits. To do otherwise could put the purchaser's investment at risk, and could conceivably create a financial liability to the Renton School District. For the above reasons, after due consideration of your request, the School Board denies your request to access the property for additional independent wetlands study.

The reason for this request to the School Board is the denial by the Superintendent to allow us to bring our own wetland specialist onto the property. We feel that this denial is unreasonable. Please notify me of your decision regarding this request by September 16, 2014 or earlier as we are running out of time to provide our findings to the City of Renton's Environmental Process.

The subject property is a collection of eight parcels located on the south side of SE 2nd Place between Field Place SE and 143rd Ave SE. The applicant is requesting a concurrent Lot Line Adjustment (LUA14- 000730) to three of the subject parcels, and an abutting parcel, in order to define the Preliminary Plat boundaries. The resulting 12.65 -acre site is located within the Residential -4 dwelling units per acre (R-4) zoning classification. The 47 lots would result in a density of 4.44 dwelling units per acre. The applicant is proposing a small lot cluster due to critical areas on site forwhich R-8 development standards would be applied. Lot sizes would range from 4,996 square feet to 19,429 square feet. In addition to the 47 lots, 5 tracts are proposed for sensitive areas, storm drainage, open space and access. Access to the plat would be gained from SE 2nd Place via a new looped public street. The site currently contains six single family residences and several detached structures all of which all would be removed with the exception of one residence to be relocated to the proposed Lot 44. The site contains a Class 2/Class 3 stream (Maplewood Creek) and critical slopes (exceeding 40%). A stormwater pond is proposed within Tract B which would discharge into Maplewood Creek.

The Planning Division accepted the above master application for review on May 15, 2014. During our review, staff determined additional information was necessary in order to proceed. On June 27, 2014 the project was placed on hold pending receipt of a Revised Traffic Analysis and Revised Wetland, Fish, and Wildlife Habitat Report. The applicant has submitted all necessary information in order to proceed. The subject property is a collection of eight parcels located on the south side of SE 2nd Place between Field Place SE and 143rd Ave SE. The applicant is requesting a concurrent Lot Line Adjustment (LUA14- 000730) to three of the subject parcels, and an abutting parcel, in order to define the Preliminary Plat boundaries. The resulting 12.68 -acre site is located within the Residential -4 dwelling units per acre (R-4) zoning classification. The site currently contains six single family residences and several detached structures all of which would be removed with the exception of one residence to be relocated to the proposed Lot 44. The project site is surrounded by existing single family subdivisions with similar densities but larger lot sizes. The 47 lots would result in a density of 4.44 dwelling units per acre. The applicant is proposing a small lot cluster due to critical areas on site for which R-8 development standards would be applied. Lot sizes would range from 4,996 square feet to 19,429 square feet. In addition to the 47 lots, 5 tracts are proposed for sensitive areas, storm drainage, open space and access. The plan includes the 3.55 acres (or 28.02%) of open space intended to meet the Small Lot Cluster requirements. Access to the plat would be gained from SE 2nd Place via a new looped public street. Two dead end shared driveways would be extended from the new looped road to provide access to proposed Lots 11, 12, 38, 44, and Tract B. The applicant is requesting a street modification, from RMC 4-6-060, in order to eliminate the requirement for frontage improvements along 143rd Ave SE and the rearrangement of required improvements for portions of SE 2nd Place. The applicant has submitted a Revised Wetland Fish and Wildlife Habitat Report, Drainage Report, Tree Protection Report, Traffic Impact Analysis, and a Geotechnical Engineering study with the application. The site contains a Class 2/Class 3 stream (Maplewood Creek) and critical slopes (exceeding 40%). The applicant is proposing stream buffer averaging in the amount of approximately 1,718 square feet to be mitigated with buffer additions in the amount of approximately 3,652 square feet. There are 272 significant trees on the site of which the applicant is proposing to retain 34 trees. A stormwater pond is proposed within Tract B, located in the southeast portion of the site, which would discharge into Maplewood Creek. The applicant is proposing excavation in the amount of approximately 20,500 cubic yards which is anticipated to be balanced on site. Staff received comment letters from the Muckleshoot Indian Tribe Fisheries Division and surrounding property owners (Exhibit 11.a -i). Questions and concerns raised included: stream classification, presence ERC Report City of Renton Department of Community & Fc- - -mic Development r- ironmental Review Committee Report COPPERWOOD PP LUA14-000550, PP, ECF, MOD Report of September 15, 2014 Page 3 of 14 of fish within the stream, stream buffer protection, stormwater quality, traffic, site distance, street modifications, erosion, privacy (trees and fencing), and density.

Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The site can best be characterized as generally flat with a slight rise in the western most portion of the site and generally sloping toward the Maplewood Creek in the east which is located within a ravine. The project site has an average slope between 3% and 5%. However, elevation relief from the top of the ravine to the base of the stream is between 14 to 20 feet with grades of ranging from 50% to 70%. The applicant is proposing excavation in the amount of approximately 20,500 cubic yards, with minor grading actions (approximately 3,000 square feet) within the stream buffer. All excavation is expected to be balanced on site. The on-site stripping (topsoil) is estimated at 14,500 cubic yards. Any excess material that cannot be used on site is expected to be exported off site. Fallowing ERC Report City of Renton Department of Community & ! nic Development ronmental Review Committee Report COPPERWOOD PP LUA14-000550, PP, ECF, MOD Report of September 15, 2014 Page 5 of 14 construction it is anticipated the proposal would result in an impervious cover of approximately 49%. The applicant submitted a Geotechnical Report prepared by Terra Associates, Inc., dated February 10, 2014 (Exhibit 7). The report states that there are no geotechnical conditions on site that would preclude the proposed development. Soil conditions on site were observed between 6 and 10 feet below existing grades. Between 6 and 12 inches of organic topsoil overlying 2 to 5 feet of medium to very dense silty sand with gravel was found within the test pits. Groundwater seepage was encountered at approximately 4 feet below the ground surface. The report states that the risk for liquefaction to occur at the site during an earthquake is negligible. The geotechnical report includes specific recommendations in order to mitigate potential geotechnical impacts including: site preparation and grading, excavation, slopes and embankments, foundation support, floor slab -on -grade, drainage considerations, and pavement. Therefore, staff recommends as a mitigation measure that the applicant comply with the recommendations included in the provided Geotechnical Engineering Report (Exhibit 7). The report includes a specific recommendation for the location of the proposed drainage pond given its proximity to Maplewood Creek ravine. The potential for seepage from the pond and its impact on soil stability is dependent on the pond stored water depth and distance from the Maplewood Creek ravine. Therefore, the report recommends the applicant provide a 50 -foot horizontal setback distance from the edge of the maximum stored water elevation in the pond to the crest of the ravine slope. As an alternative to a setback the applicant may choose to line the pond with a flexible membrane liner to prevent seepage losses. Given the possible impact on the preliminary plat plan staff recommends, as a separate mitigation measure, the applicant provide a 50 -foot horizontal setback distance from the edge of the maximum stored water elevation in the pond to the crest of the ravine slope. As an alternative to a setback the applicant may choose to line the pond with a flexible membrane liner to prevent seepage losses. The drainage plan shall be submitted to, and approved by, the Plan Reviewer prior to construction permit approval. Soil erosion is possible during demolition of existing structures and improvements especially if conducted in the wet season. The applicant will be required to design a Temporary Erosion and Sedimentation Control Plan (TESCP) pursuant to the current 2009 King County Surface Water Design Manual Erosion and Sediment Control Requirements. However, sedimentation due to development projects has been a major problem in Maplewood Creek for decades, and it compromises the successful efforts of the State Department of Transportation (WSDOT) and the City of Renton to re -introduce salmon into the creek. WSDOT built a fish passage channel in the culvert under SR 169 which carries Maplewood Creek into the Cedar River_ Additionally, the City has invested hundreds of thousands of dollars building a sedimentation pond with a fish ladder upstream of the Maplewood Golf Course, and as a result of these investments salmon have now returned to the upper creek. The ongoing transport of sediments down the creek compromises the fish habitat. Every year Renton spends $70,000 cleaning sediment deposits out of the Maplewood Creek Sedimentation Pond, and the City has programmed $1.6 M between the years 2014 and 2017 to resolve existing erosion, flooding, water quality, and habitat degradation problems in Maplewood Creek. Major construction projects adjacent to the creek that will strip, disturb and excavate topsoil must be restricted to the dry weather months to prevent bank erosion and deposition of sediment -laden runoff into Maplewood ERC Report City of Renton Department of Community & mic Development ronmentol Review Committee Report COPPER WOOD PP _ LUA14-000550, PP, ECF, MOD Report of September 15, 2014 Page 6 of 14 Creek. Therefore staff recommends, as a mitigation measure, that the site construction be restricted to the dry weather months (April 1st through September 301h) Mitigation Measures: 1. All earthwork performed, implemented by the applicant, shall be consistent with the recommendations of the geotechnical report, prepared Terra Associates, Inc., dated February 10, 2014. 2. The applicant shall provide a 50 -foot horizontal setback distance from the edge of the maximum stored water elevation in the pond to the crest of the ravine slope. As an alternative to a setback the applicant may choose to line the pond with a flexible membrane liner to prevent seepage losses. The final drainage plan shall be submitted to, and approved by, the Plan Reviewer prior to construction permit approval. Nexus: SEPA Environmental Regulations, RMC 4-4-060 Grading, Excavation, and Mining Regulations 2. Water a. Wetland, Streams, lakes impacts: The applicant submitted a Wetland, Fish and Wildlife Habitat Assessment (Exhibit 6), prepared by Soundview Consultants. (dated May 27, 2014). The report identified one stream (Maplewood Creek) on the eastern side of the property. Maplewood Creek is classified as a Class 3 non -salmonid -bearing perennial stream pursuant to the City's Stream Classification Map. The onsite segment of the tributary is approximately 755 feet (combined) long flowing north to south in the eastern most portion of the parcel. The stream leaves the site and turns west. North of the culvert under SE 2"d Place, Maplewood Creek is identified as a Class 4 waterbody. The report also states that salmonid species are not present until further downstream. In the northern portion of the subject property, the stream is low -gradient with gently -sloping banks; however, in the southern portion of the property, the channel is located in a ravine with steeply sloped banks and several natural fish passage barriers. Onsite, the buffer consists of deciduous riparian forest with a canopy dominated by black cottonwood and red alder. Some areas of the understory include native shrubs, primarily salmonberry, but many areas are dominated by Himalayan blackberry and other non-native invasive species. Portions of the offsite buffer are modified with moderate to high density development on adjacent properties to the east. In addition, a gravel driveway and piles of yard waste and debris are located in onsite areas of the western portion of the buffer associated with adjacent single-family residences and maintained neighboring yards. The report also notes an artificially constructed swale with emergent wetland vegetation also found onsite draining into the onsite creek. The swale is documented to have been constructed in 1993 as a landscape and drainage feature and the report states the wetland is not regulated by the City of Renton. A comment letter was received by Muckleshoot Indian Tribe Fisheries Division with comments regarding the presences of salmonid species in addition to concerns for water quality (Exhibit 11.a). The comment letter identified fishes below a natural fish passage barrier in the southeast corner of the subject site. ERC Report City of Renton Department of Community & E tic Development onmentui Review Committee Report COPPERWOOD PP [11A14-000550, PP, ECF, MOA Report of September 15, 2014 Page 7 of 14 Following the receipt of comments from the Muckleshoot Indian Tribe Fisheries Division the applicant conducted a site visit in order to investigate for the presence of fish habitat. A revised Wetland, Fish and Wildlife Habitat Assessment (dated July 14, 2014) was submitted verifying fishes below a natural fish passage barrier necessitating the reclassification of this reach as a Class 2 salmonid -bearing stream (Exhibit 5). The report states there are several natural fish barriers within the onsite stream reach between the Class 2 and Class 3 waters. As a Class 2 and Class 3 stream, Maplewood Creek requires a buffer width of 100 feet and 75 feet, respectively. The reclassification of the stream as a Class 2 salmon -bearing stream required revisions to the buffer management recommendations in order to address increased buffer requirements. No impacts are proposed to the stream, and only minor impacts are proposed to the stream buffer, which would be addressed by buffer averaging and enhancement actions. The drainage facility would require placement of a stormwater outfall and pervious walking trail along with minor grading actions (approximately 3,000 square feet) within the stream buffer and minor buffer reduction via buffer averaging in the southeast corner of the site. Any impacts associated with the installation of the outfall, trail, minor grading, and buffer averaging would be mitigated for through non -compensatory enhancement actions. The proposed buffer averaging plan decreases the buffer by approximately 1,730 square feet to be averaged by 3,172 square foot buffer increase for a net increase in the overall buffer area on the site by 1,442 square feet (Exhibit 12). With buffer averaging and minor buffer enhancement and restoration measures, the modified Class 2 and 75 - foot Class 3 buffers are anticipated to be more than adequate to protect stream functions. Conditions associated with Preliminary Plat approval will likely include stream signage and fencing and review and approval of a final stream buffer mitigation plan. In order to preserve and protect the stream and associated buffer the applicant will be required, to record the Native Growth Protection Easement over that part of the site encompassing the stream and buffer area. Mitigation Measures: No further mitigation needed Nexus: Not applicable b. Storm Water Impacts: The site is located within the Lower Cedar River drainage basin. The site currently receives drainage from properties to the north. The applicant submitted a Preliminary Drainage Report prepared by Barghausen, dated June 2, 2014 (Exhibit 8). Based on the City's flow control map, this site falls within the Flow control Duration Standard Forested site conditions area. The report states that the runoff from the proposed project would be collected and conveyed by a catch basin/pipe network to a detention/wet pond on the southern edge of the developed area. The proposed facility would then discharge into the onsite stream. The storm pond is designed per the 2009 King County Surface Water Design Manual as amended by the City of Renton. The report states that the project should not pose significant negative impacts to the downstream drainage course and that Basic Water quality is required for the project. However, staff received comments, from surrounding property owners, with respect to drainage concerns for the proposal and areas downstream (Exhibit 11). Severe erosion problems can be ERC Report City of Renton Deportment of Community & E tic Development onmentol Review Committee Report COPPERWOOD PP LUA14-000550, PP, ECF, MOD Report of September 15, 2014 Page & of 14 caused by conveyance system overflows or the concentration of runoff in erosion -sensitive open drainage features. As mentioned earlier in the report sedimentation due to development projects has been a major problem in Maplewood Creek for decades. It is unclear if the potential for erosion/incision, caused by the proposed project, is sufficient enough to pose sedimentation hazard downstream. Therefore, staff recommends as a mitigation measure that the final drainage report include a more detailed upstream, downstream, and potential erosion analysis. Per CORE requirement #2, a Level 2 downstream analysis is required to better understand erosion and possible concentration of runoff in erosion sensitive downstream bodies. The applicant should note that Level 3 flow control could be required as part of the Level 2 downstream analysis. A revised final drainage report and associated plans, based on the 2009 King County Surface Water Design Manual as amended by the City of Renton, is required to be submitted to the satisfaction of the Plan Reviewer prior to construction permit approval. Additionally, the Enhanced Basic water quality menu is intended to apply to all project sites that drain by surface flows to a fish bearing stream. Given there have been fish identified in the lower reach of the stream on site staff recommends a mitigation measure requiring the applicant to design the proposed drainage facility utilizing the Enhanced Basic water quality menu. A revised final drainage report and associated plans utilizing the Enhanced Basic water quality menu , based on the 2009 King County Surface Water Design Manual as amended by the City of Renton, is required to be submitted to the satisfaction of the Plan Reviewer prior to construction permit approval. Finally, an existing administrative interpretation requires all drainage facilities be required to maintain up to a 15 -foot vegetated buffer around drainage pond facilities (Exhibit 15). Conditions associated with Preliminary Plat approval will likely include the requirement to submit a revised landscape plan, prior to recording of the Plat, depicting up to a 15 -foot landscape buffer around the proposed drainage facility. Mitigation Measures: 1. The final drainage report shall include a more detailed upstream, downstream, and potential erosion analysis. Per CORE requirement #2, a Level 2 downstream analysis is required to better understand erosion and possible concentration of runoff in erosion sensitive downstream bodies. The applicant should note that Level 3 flow control could be required as part of the Level 2 downstream analysis. A revised final drainage report and associated plans, based on the 2009 King County Surface Water Design Manual as amended by the City of Renton, is required to be submitted to the satisfaction of the Plan Reviewer prior to construction permit approval. 2.

Review Committee Report COPPER WOOD PP LUA14-000550, PP, ECF, MOD - Report of September 15, 2014 Page 9 of 14 Impacts: The majority of the site has been cleared and developed with single family residences. Most of the vegetated areas are dominated by landscaped areas and mowed lawn. The species found on site include Douglas fir, bigleaf maple, Scouler's willow, red alder, Pacific madrone, cherry species, cypress species, vine maple, Katsura tree, Hinoki cypress, European white birch, western red cedar, flowering plum, western white pine, Colorado blue spruce, black cottonwood, honey locust, and western hemlock. The understory primarily consists of Salmonberry, vine maple, western hazelnut, salal, Oregon grape, and Pacific blackberry. The applicant submitted a Tree Protection Report prepared by Washington Forestry Consultants, Inc. (dated August 8, 2014) (Exhibit 13). There are a total of 272 trees located on site. The applicant is required to retain 30 percent of the trees located on site that are not located within critical areas, proposed rights-of-way and access easements. Of the 272 trees located on site 160 trees would be excluded from the tree retention requirements. The provided tree retention worksheet indicates 69 trees are considered dead diseased or dangerous, 27 trees are located within proposed public streets/private access easements, and 64 trees are located within critical areas and their buffers. Therefore, the applicant would be required to retain at least 34 trees on site. The applicant has proposed to retain 34 trees outside of the critical area and its associated buffer thereby complying with Tree Retention requirements of the code (Exhibit 14). The provided Tree Retention Report includes a specific recommendations for inspection of retained trees after initial clearing, final grading, and annually for two years by a qualified professional forester to identify those retained trees that develop. problems dues to changing site conditions and prescribe mitigation (Exhibit 13). Therefore staff recommends, as a mitigation' measure, the applicant be required to provide, to the Current Planning Project Manager, tree retention inspection/monitoring reports after initial clearing, final grading, and annually for two years by a qualified professional forester. The inspection/monitoring reports shall identify any retained trees that develop problems due to changing site conditions and prescribe mitigation. The applicant also provided a conceptual landscape plan as part of the Preliminary Plat submittal which included the planting of 45 trees on site (Exhibit 3). Conditions associated with Preliminary Plat approval will likely include the provision of a 10 -foot wide on-site landscaping along the street frontage of all lots and the planting of additional vegetation along the western boundary in order address privacy concerns of interested parties. Mitigation Measures: 1. The applicant shall be required to provide, to the Current Planning Project Manager, tree retention inspection/monitoring reports after initial clearing, final grading, and annually for two years by a qualified professional forester. The inspection/monitoring reports shall identify any retained trees that develop problems due to changing site conditions and prescribe mitigation. Nexus: SEPA Environmental Regulations 4. Habitat Impacts: A revised Wetland, Fish and Wildlife Habitat Assessment (dated July 14, 2014) was submitted verifying fishes below a natural fish passage barrier necessitating the reclassification of lower reach of Maplewood Creek on site as a Class 2 salmonid -bearing stream (Exhibit 5). Native ERC Report City of Renton Department of Community & E iic Development onmental Review Committee Report COPPERWOOO PP LUA14-000550, PP, ECF, MOD Report of September 15, 2014 Page 10 of 14 habitat would be provided on site through the preservation of approximately 3.55 acres of permanent native open space tracts. The existing buffer onsite is degraded by the dominance of invasive Himalayan blackberry, the presence of yard waste and debris piles, and a gravel driveway. The applicant proposes enhancement efforts within the stream buffer to include treatment and removal of invasive vegetation, removal of yard waste and debris piles, and planting with native trees and shrubs. The proposed project is anticipated to improve stream buffer functions which would enhance the wildlife habitat if all conditions of approval are met. Mitigation Measures: No further mitigation needed Nexus: Not applicable 5. Transportation Impacts: The development fronts onto SE 2nd Place, a residential access street, just west of 143rd Ave SE. The site is within close proximity to King County Metro Routes #111 (along Jericho Ave SE and SE 2"d Place) and #908 (dial -a -ride). The proposal includes 1,226 linear feet of public roadway (with utilities) improvements in order to provide access to proposed lots. Access to the plat would be gained from SE 2nd Place via a new looped public street. Two dead end shared driveways would be extended from the new looped road to provide access to proposed Lots 11, 12, 38, 44, and Tract B. Level of Service: The applicant submitted a Traffic Impact Analysis prepared by TranspoGroup, dated May, 2014 (Exhibit 9). The report states that the proposed development would generate approximately 390 net new daily trips. During the weekday AM peak hour, the project would generate approximately 31 net new trips (8 inbound and 23 outbound). During the weekday PM peak hour, the project would generate approximately 41 net new trips (26 inbound and 15 outbound). The report also analyzed the level of service at the following intersections: NE 4th St/Jericho Ave NE, SE 2nd Place/Hoquiam Ave SE, and SE 2nd Place/Jericho Ave SE. The traffic study states that these intersections will continue to operate at an acceptable level of service. Staff received comments from interested parties concerning the existing SE 139th Ave & SE 2nd Place intersection specifically related to sight distance concerns (Exhibit 11). City staff conducted an analysis of the intersection and determined a STOP sign is needed at the intersection. Additionally, staff has concluded due to the vertical curve in the street there is a visibility concern and that an intersection warning sign on the north side of SE 2"d Place is necessary to warn west bound traffic of the SE 139th Ave & SE 2nd Place intersection. While the proposed project will increase traffic at this intersection the site distance issues at this intersection are existing and not the responsibility of the applicant for complete mitigation. Therefore, the City of Renton Transportation Department is planning on providing the necessary improvements to this intersection. Increased traffic created by the development would be mitigated by payment of transportation impact fees. Currently this fee is assessed at $1,430.72 per new single-family home and will increase January 1, 2015 to $2,143.70. The fee, as determined by the Renton Municipal Code at the time of building permit issuance shall be payable to the City. Frontage Improvements: FRC Report City of Renton Department of Community & E r!c Development onmental Review Committee Report COPPERWOOD PP LUA14-000550, PP, ECF, MOL) Report of September 15, 2014 Page 11 of 14 All internal and frontage roads are required to meet street standards pursuant to RMC 4-6-060. The internal public streets have been proposed with a right-of-way width of 53 feet which meets the City's complete street requirements for residential access streets. Pavement width of 26 feet, 0.5 foot wide curbs, 8 foot wide landscaped planters (on both sides of the street), 5 foot wide sidewalks (on both sides of the street), drainage improvements, and street lighting are required. The applicant is not proposing any modifications for the internal road network. However, the applicant is requesting a street modification, from RMC 4-6-060, in order to eliminate the requirement for frontage improvements along 143rd Ave SE and the rearrangement of required improvements for portions of SE 2nd Place. SE 2nd Place- The existing right of way varies from 30 to 60 feet. Pursuant to RMC 4-6-060 the required right-of-way width is 53 feet however given the existing 60 feet the applicant is proposing dedications which would provide a 60 -foot right-of-way width for SE 2nd Place. This would allow for 26 foot of pavement, 5 -foot sidewalk, 8 -foot landscape planter strip, 0.5 foot curb on the south side of the street. The modification request for SE 2nd Place is to solely allow for the rearrangement of required improvements for a small portion of SE 2nd Place to construct the sidewalk adjacent to the curb (Exhibit 2) as opposed to having a landscape planter in between the curb and the sidewalk. The request is being made in order to reduce impacts to Maplewood Creek where it enters into the site. As part of the PP recommendation to the Hearing Examiner, staff will be recommending approval of the proposed SE 2 Place cross section. The approval would likely include the following conditions of approval: 1. Corresponding to the eastern boundary of Maplewood Creek buffer the applicant would be required to revise the street improvement plan to transition to the code required street standard with the landscaping in between the sidewalk and the curb. 143rd Ave SE — The existing right of way width is 60 feet. Pursuant to RMC 4-6-060 the required right-of-way width is 53 feet however given the existing 60 feet the applicant is proposing leave the right of way width as is. However, a modification, along 143rd Ave SE, is being requested due to the location of Maplewood Creek and if improvements are constructed along the west side of 143rd Ave SE (as required per code) the stream would need to be piped. As part of the PP recommendation to the Hearing Examiner staff will likely be recommending approval of the 143 rd Ave SE cross section. The approval would likely include the following condition of approval: 1. The applicant would be required to place a split rail fence along the eastern boundary of the Maplewood Creek ravine adjacent to the modified 143rd Ave SE street. A concurrency recommendation will be provided in the staff report to Hearing Examiner based upon the test of the citywide Transportation Plan, consideration of growth levels included in the LOS -tested Transportation Plan, payment of a Transportation Mitigation Fee, and an application of site specific mitigation. The development will have to meet the City of Renton concurrency requirements.

After reading the notice, I have the following questions/concerns: 1. Taken into account of improvements (such streets, pond, etc.), I am concerned that the net acreage will make this development exceeds R-4 (or R4.4 as stated in the notice). I would to request a detailed calculation be made to ensure that no zoning laws are violated. 2. Although I am not sure what exemption the applicant is requesting regarding RMC 4-6-060 for street modification, I would like to bring a concern to the city. The north boundary of this project (along the south side of 2nd SE PL) is unimproved and including uneven ditches, covert drainage, etc. Currently, pedestrians have to walk along and on the street. This poses a safety hazard. This will become more critical as the project will more than double the dwellings for the area. A sidewalk with street lights along the entire north side of the project should be required as part of the improvement. This is very critical as this would be the only sidewalk that will allow children and pedestrians to walk from this development to the Maple Wood Height Elementary School without interruption. The north side of SE 2nd PL has a small strip of sidewalk which is too short and on the wrong side of the foot traffic. Your effort to review these concerns would be greatly appreciated. You may also contact or communicated with me at 425-306-9064 orgmgotv@gmail.com. Sincerely, VVV L Ti C.

My property and those of my neighbors have a very high water table. if the developers bring in any fill to raise the grade of the property for the proposed Copperwood Plat especially in the Southwest side I have a fear that my septic system will fail. That area is now pasture and lays lower than the rest of the adjacent land. By raising the grade of the property water would not be able to flow below my drain field. am not against the development but fear there will be repercussions including but not limited to flooding of property and failure of septic systems if fill is brought on to the property. I would also request that they install an eight foot fence along the southern border due to the fact that I have an in ground pool and by building 40 plus houses I can see it being a safety concern for children trying to enter my property to enter my pool. Please keep me informed on the plans and any other information regarding the development of this property/plat. Please take into consideration the very high water table that exists on the southern border of the plat prior to making decisions regarding the development of this property. Please contact me if you would like me to provide additional detailed information regarding the issues that currently exist when it rains in regards to the high water table.

My name is Jim Hageman and 1 live right across the street from the subject project and I have some questions about this. But first, please put me on the correspondence list for further information. Here's our address: 4910 SE 2nd Place, 98059-4959 My question(s) regarding this project have to do with the general impacts this project will have on the neighborhood, good and bad. Reading the notice of application letter doesn't really say much in layman's terms of benefits and/or pitfalls for those around this development. One specific item mentioned in the letter that is not explained is a mention that the applicant is requesting a street modification "...in order to eliminate the requirement for... rearrangement of required improvements for portions of SE 2nd Place." (my street) Can you expand on what this means? How can the applicant do anything at all to 'eliminate the requirement'? If its a requirement, doesn't it remain a requirement? I really don't know what this means and am looking for some explanation.

My name is Rob Willits and my neighbors and I are very concerned about the intersection at SE 2nd Place and 139th Ave SE. I grew up on 139th Ave and now own the home that my parents bought back in 1967 so I know this neighborhood very well. This particular intersection has always been dangerous, but do to low traffic volumes there have not been many incidents. Leaving our neighborhood, if you look to the left there is a blind corner and if you look to the right there is a hill. So even if you are cautious you cannot be sure that no traffic is coming. This new proposed development, Copperwood, will only increase traffic through this area and make this intersection even more dangerous. I'm sure that you are looking at all aspects of this development and I hope this intersection gets some attention. I've talked with at least a half dozen of my closest neighbors and we would all like to see a 3 way stop implemented for our safety. Thanks for your time and consideration.

The Analysis totally fails to address the traffic impacts of this sixty percent of the increased traffic resulting from the building of COPPERWOOD. The Traffic Impact Analysis needs to be revised to address the traffic impacts that will result from the estimated 240 additional vehicle trips per day along SE 2"d PL. west of the COPPERWOOD PLATT. The intersection of SE 2nd PI and SE 139`" Ave needs to be included in the Traffic Impact Analysis due to the existing safety issues related to impaired visibility. There is a vertical rise in SE 2nd PI immediately east of the subject intersection of approximately eight (8) feet, cresting at a location thirty (30) feet to the east of where SE 140th Ave. tees into SE 2nd PL. This elevation increase on 2nd PI SE going East from the intersection with SE 139th Ave severely limits the visibility of oncoming cars traveling West on SE 2nd PL. The west bound traffic on SE 2nd PL. is frequently traveling 35 to 40 mph instead of the posted 25 mph. The additional west bound traffic on SE 2nd PL. resulting from the development of COPPERWOOD will further increase the safety risks for those of us who frequentl y turn left from SE 139th Ave. onto SE 2nd PL. There is an additional safety related issue with the narrow 90 degree corner of SE 2nd PI and SE 138th Ave (Duvall Ave. SE). A large portion of the traffic coming south on Duvall cuts across this corner to the inside lane at higher than appropriate speed for this corner. Since there is essentially no visibility of oncoming traffic for cars approaching this corner on SE 2nd PI headed west, it would be much safer if oncoming traffic would remain in their designated lanes through this corner. I realize that Renton has recently (within the last week) repainted a double yellow centerline around this corner but 1 observed today that a number of cars continue to cut across to the inside lane while taking this corner at excessive speed. Additional measures are required to cause cars to remain in their correct lanes to reduce the likelihood of head on collisions just east of this corner. This existing hazard will be aggravated by the increased volume of traffic that will result from the construction of COPPERWOOD_ There are currently more traffic congestion problems at the intersection of NE 0 St and Duvall Avenue SE. than the intersection of NE 4th ST. and Jericho Avenue SE. which is included in the Traffic Impact Analysis. Recent increases in traffic going north on Duvall are resulting in long lines of cars (10 to 12 cars) waiting for the light on the South side of NE 4th St. This line of cars waiting for the light blocks the entrance from Duvall to the Dairy Queen which is located on the SE corner of NE 4th St. and Duvall. When cars traveling South on Duvall are not able to make the left turn into the Dairy Queen driveway due to the long line of cars waiting for the light in the northbound lane, traffic backs up into tie 5 � intersection of SE 4th St and Duvall Ave. SE.

Complaints about conveyance nuisance problems and existing severe Erosion problems are likely recorded with King County and not with the City of Renton. To only review City of Renton reports of downstream erosion problems for Maplewood Creek Tributary 0303 does not identify the longstanding problems known to King County. King County records of erosion problems of Maplewood Creek Tributary 0303 should be reviewed and acknowledged in this report. Attached to this email is a series of pictures I took during this past week of some of the erosion damage that has recently occurred on the portion of Maplewood Creek Tributary 0303 that passes through my property. My property begins just downstream of the nearly ninety degree turn that Maplewood Creek makes from a generally north -south direction as it passes through the Copperwood Plat to a westerly direction a short distance south of the Plat as shown on the maps included in the subject report. Along this nearly six hundred feet of Maplewood Creek streambed that I own there have recently been a number of large evergreen trees topple over due to washing out the soil under these trees along the creek bed. One large cedar tree recently fell in a southerly direction from the north edge of the creek into the back yard of the house at the top of the ravine missing the roof only by a few feet. The large root ball of this tree remains in the stream bed partially blocking the stream flow. I believe this report should be revised to acknowledge there are serious erosion problems currently existing below the proposed development Site. Thank you for your consideration of this issue.

Rocale these are a few concerns of our community, over the last few years due to progress, we have experienced the changes with all the many new developements around us. All these many projects have drainage that goes into Maple Creek. These many projects have cut hundreds of trees, we realize they have retention ponds with slow release, but as to the CopperWood Plat not only are tItAremoving trees, the retention pond is only 75 ft from the upper end of the canyon correcting with Maple Creel& We have pictures that show the water flow of last April at an all time high, which is a big concern to all the propertyyalong the bluff above Maple Creek canyon. The hill sides have had many varied slides this last year and is a concern with the water increasing, not only from all the developements but the fact that this area has thousands of under grounds springs as historically the area has had some serious slides. The holding ponds will not contain or direct any of the under ground springs. In a strong storm season we are very concerned with the water flow of the holding ponds and what will happen in extreme cases, t when the etention ponds cant handle the extreme over flow and the water rises in in the canyon causing deteriation to the creek bed and sides only to make slides even more possible, putting homes along the canyon in danger of serious property damage oA loss of a home. This project could be the one to break the back of the homes on the canyon edge, how will you protectrMaple Creek We realize we are in uncorporated King County and this is a Renton Annexed Plot but we would like someclearity and assurance these concerns are addressed. Note; Neighbors have said they used to hear the creek from their homes but now they can see the creek, the canyon is changing and the water flow is rising.

The proponent has retained WFCI to: • Evaluate the health and long -terra survival potential for trees 6 inches diameter at breast height (DBH) and larger within the buildable area of the site and make recommendations for retention, protection, and necessary cultural care. • Prepare a list of all trees with their corresponding size, condition and potential for retention, along with their minimum root protection zone required if they are to be saved. • Complete required tree retention calculations as per the City of Renton ordinance Section 44-130. • Evaluate'soils with respect to impacts on tree growth and stability. Observations Methodology WFCI has evaluated trees 6 inches diameter at breast height (DBH) and larger in the proposed project area, and assessed their potential to be incorporated into the new project. The tree evaluation phase used methodology developed by Nelda Matheny and Dr. James Clark in their 1998 publication Trees and Development: A Technical Guide to Preservation of Trees During Land Development.

CODE SECTIONS: RMC 4-6-030 Drainage (Surface Water) Standards REFERENCE: N/A SUBJECT: Landscaping, fencing, pond slopes, and other standards for stormwater tracts and easements and ownership and maintenance responsibility for stormwater facilities. BACKGROUND: The current drainage code (RMC 4-6-030) references the current Icing County Surface Water Design Manual (KCSWDM) for compliance with stormwater standards. Requirements for landscaping in stormwater facility tracts are included in Section 5.3.1.1 of the 2009 KCSWDM as amended by the City of Renton. Section 5.3.1.1 of the KCSWDM restricts planting in berms that impound water or within 10 feet of any structure. Requirements for pond geometry and side slopes are listed in Section 5.3.1.1 of the 2€109 KCSWDM, as amended by the City of Renton. Adopted standards allow for the side slopes of an open detention or water quality treatment facilities (pond, wetpond, stormwater wetland, etc) to be steeper than 3:1 if a fence is provided along the wall and/or around the emergency overflow water surface elevation. This standard is resulting in facilities that are difficult to maintain, expensive in labor and materials for maintenance, and create a safety hazard to the maintenance crews. Fencing requirements are also standardized in section 5.3.1.1 of the 2009 KCSWDM, as amended by the City of Renton. A fence is required to discourage access to the stormwater pond, prevent litter, allow efficient maintenance, and in consideration of worker and public safety. JUSTIFICATION: Recognizing that requirements for landscaping and tree planting contribute to the aesthetics and value of new surface water installations while needing to ensure proper functionality and maintenance of facilities, both the Department of Public Works and the Department of Community and Economic Development desire to clarify standards H.\CED\P1anning\7n11e rADocket\Adrrinistrat3Ve Policy Code Interpretat1on\Cl-38Nt EXHIBIT 15 DECISION: DEVELOPMENT SERVICES DIRECTOR APPROVAL UTILITY SYSTEMS DIRECTOR APPROVAL DATE: APPEAL PROCESS: pertaining to the landscaping requirements applicable to stormwater facilities. Concerns for public safety have also raised questions regarding the necessity of more extensive fencing requirements for drainage facilities as well as lesser side slopes for flow control and/or water quality treatment ponds. This interpretation is intended to provide guidance and consistency for projects currently under review. Briefly, this determination clarifies: Fencing Requirements: All flow control and/or water quality treatment ponds shall be fenced. Fence material shall be six foot black or green coated chain link. Cedar or other materials may be installed only if owned and maintained by a private property owner or Home Owner's Association (HOA). Landscaping Requirements: Landscaping is required in those areas of the tract/easement that will not impact the functionality or maintenance of the facility. The fence shall be placed at the top of the berm with the maintenance access road in the inside of the fence; or 5 feet min from top of berm if there is no maintenance access road to allow access for proper maintenance of the facility. No landscaping shall be planted inside the fence line. Pond Geometry and Side Slope Requirements: Side slopes interior and exterior) shall not exceed three (3) feet horizontal one foot (1) vertical.

Hearing. The Examiner held a hearing on the subject application on September 18, 2013 at 1:30 pm in the City of Renton Council Chambers. Substantive: 3. Project Description. The City of Renton is requesting a shoreline substantial development permit and shoreline conditional use permit in order to install 3,330 linear feet of a 60 -inch diameter storm drain parallel to an existing storm system, from its current outfall at Naches Ave SW to approximately Lind Ave SW. Most of the project would occur within the rights-of-way of SW 71 St and Naches Ave with a short segment (approximately 50 linear feet) within an undeveloped City owned parcel (Parcel #9188000154) on the west side of Naches Ave SW. The project includes the construction of an additional stormwater outfall in a Class 2 stream (Stream A) that runs east to west on the northern boundary of the City -owned property (Parcel #9188000154). The project would also retrofit the drainage condition installing Filterra Systems along SW 7th St; from Naches Ave SW to Lind Ave SW. The project site is primarily located within the public right-of-way. The portion of the project area west of Powell Ave SW is zoned Commercial Office (CO). The eastern portion of the project area is zoned Medium Industrial (IM). The area of impact would be approximately 270,000 square feet and is largely undeveloped with the exception of utilities. Construction is expected to begin in Spring of 2014 and be complete by June of 2015. 4. Surrounding Area. The project area is located in a wildlife conservation area associated with the Black River Riparian Forest. Adjoining parcels are characterized by warehouse and office use. 5. Adverse Impacts. There are no significant adverse impacts associated with the project_ As an underground utility project, the proposal will not create any post -construction noise, traffic, parking, navigation or visual impacts. As to compatibility, the project is located within the public right-of- way. ight-ofway. Construction traffic is addressed by MDNS mitigation. Surrounding land uses include both commercial and industrial properties. The proposed storm drain, to be installed adjacent to the existing storm system would not alter the existing land uses in the area and has already proven to be compatible. Water quality will not be adversely affected by the proposal. Overall the proposal will improve water quality in the Black River basin and the project will incorporate Filterra systems to provide for enhanced basic water treatment. The staff report notes that it is unlikely that any cultural or archaeological resources are present at the site and the MDNS requires actions to be taken should any resources be discovered during construction. The primary impacts of concern are impacts to wetlands and a stream, more specifically addressed as follows: A. Wetlands. There are two wetlands within the project area. A Wetland Assessment Report and Buffer Mitigation Plan was submitted by the applicant, prepared by Herrera on May 24, 2013 (Exhibit 4). Hererra biologists delineated SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 2 2 3 4 5 6 7 S 9 10 Il 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 the two wetlands and identified them as Wetlands A and B. Wetland A, a Catergory 1 wetland, is a large palustrine forested depressional wetland complex that is contiguous with the Black River Riparian Forest which is subject to the Renton Shoreline Master Program (RMC4-3-090). Wetland B, a Category 3 wetland, is a palustrioe forested wetland that occupies the southern portion of the City -owned parcel and is also subject to the Renton Shoreline Master Program (Exhibit 10). No work would occur within the wetlands themselves, but 700 square feet would be temporarily cleared in the buffer to Wetland A. Mitigation requires re -vegetation of the cleared area. The mitigation recommended in the Herrera report was prepared by a qualified professional and was accepted by staff. The recommended mitigation adequate mitigates wetland impacts and is imposed through the MDNS. B_ Stream. An unnamed tributary to the BIack River (Stream A) is also located within the project area. A Stream Study was submitted by the applicant, prepared by Herrera on May 24, 2013 (Exhibit 6). The stream was classified as a Class 2 stream with a 100 -foot buffer. The existing 60 -inch storm drain connects directly to Stream A within the culvert crossing of Naches Ave SW. The new 60 -inch storm drain will outfall adjacent to the existing culvert outlet_ The stream at this location is currently armored with rock. A temporary stream bypass will be necessary to construct the outlet. Since the buffer of Stream A overlaps with the buffer of Wetland A, buffer impacts and consequent performance standards are included in the Wetland Assessment Report and Buffer Mitigation Plan (Exhibit 4). The Muckleshoot Tribe submitted written comment expressing concern over an increase in stream velocity that would be caused by the new outfall location into the stream. That increased velocity could adversely affect protected fish. In response to this concern staff added mitigation requiring the addition of large woody debris to the stream. Staff and the Tribe found this additional mitigation to adequately address velocity impacts and the mitigation is imposed through the MDNS. The tribe also suggested the use of alternative vegetation for the required planting plan and the applicant has agreed to consider it. C, No Net Loss of Ecological Function. The proposal will not crate any net loss of ecological shoreline function. The project includes temporary impacts to the buffer of Wetland A amounting to an approximately 700 square foot area of vegetation clearing_ The Wetland Assessment Report and Buffer Mitigation Plan contains a buffer mitigation and vegetation management plan for the re -vegetation of cleared areas (Exhibit 4). The plan includes approaches for no net loss of ecological functions and for mitigation sequencing. Proposed performance standards are described to compensate for unavoidable temporary impacts to buffers. There are provisions for re -vegetating cleared areas with native plant SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 3 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 species and removing invasive plant species_ The applicant is proposing to plant Douglas fir and black cottonwood trees, snowberry and beaked hazelnut shrubs, and sword fern. The maintenance and monitoring program is proposed for a minimum of five years to ensure adequate establishment of installed vegetation and adequate cover of native vegetation and trees. A mitigation measure, as part of the SEPA determination, was issued requiring the submittal of a detailed final mitigation plan (Exhibit 13). The final mitigation plan will be required to be reviewed and approved by the Current Planning Project Manager, prior to the approval of construction permits. Conclusions of Law 1. Authority. RMC 4-8-080(G) classifies shoreline substantial development permits as Type H applications and shoreline conditional use permits as Type III applications. RMC 4-8-080(C)(2) requires consolidated permits to each be processed under "the highest -number procedure". The shoreline variance has the highest numbered review procedure, so both shoreline permits must be processed as Type III applications. As Type III applications, RMC 4-8-080(G) grants the Examiner with the authority to hold a hearing and issue a final decision on them, subject to closed record appeal to the City Council. 2. Shoreline Designations. Natural. 3. Review Criteria. RMC 4-3-090(E)(1) requires shoreline conditional use permits for structures for floodway management, including drainage facilities. Conditional use criteria are governed by RMC 4-9-030(D). The criteria for shoreline substantial development permits are set by RMC 4-9-190(B)(7), which requires compliance with all SMP use regulations and substantial compliance with SMP policies. All applicable criteria are quoted below in italics and applied through corresponding conclusions of law. The staff report analysis of compliance with RMC 4- 3.090(D) is adopted and incorporated by this reference as if set forth in full. SMP Policies SMP Objective U -F: Provide and maintain surface water management systems to minimize impacts on natural systems and to protect the public, property, surface water bodies, fish habitat, and groundwater from changes in the quantity and quality of storm water runoff due to land use changes. 4. As determined in FOF No. 5, as mitigated the proposal will not adversely affect stream or wetlands and those are the only natural systems potentially affected by the proposal. No impacts to public property are anticipated since the proposal will be primarily located underground. SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 4 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SMP Policy SH -6: Shoreline use and development should he carried out in a manner that prevents or mitigates adverse impacts so that the resulting ecological condition does not become worse than the current condition. This means ensuring no net loss of ecological functions and processes in all development and use. Permitted uses should be designed and conducted to minimize, in so far as practical, any resultant. damage to the ecology and environment (RCW 90.58.020)_ Shoreline ecological functions that should be protected include, but are not limited to, fish and wildlife habitat, food chain support, and water temperature maintenance. Shoreline processes that shall he protected include, but are not limited to, water flow; littoral drift; erosion and accretion; infiltration; ground water recharge and discharge; sediment delivery, transport, and storage; large woody debris recruitment, organic matter input; nutrient and pathogen removal; and stream channel 5. As determined in FOF No. 5, the only ecological systems potentially affected by the proposal are wetlands and streams and no adverse impacts are anticipated as to those resources. As further determined in FOF No. 5, the proposal will not result in any net loss of ecological function. RMC 4-3--090(E)(11)(a)(i): Local utility services needed to serve water -dependent and other permitted uses in the shoreline are subject to standards for ecological protection and visual compatibility. 6. As determined in FOF No. 5, the proposal will not create any adverse ecological or visual impacts_ RMC 4-3-090(E)(11)(a)(i.i): Major utility systems shall be located outside of shoreline jurisdiction, to the extent feasible, except for elements that are water -dependent and crossings of water bodies and other elements of shorelands by linear facilities. 7. The proposal cannot be placed outside the shoreline jurisdiction since it involves the relocation of an existing water dependent storm water system that discharges into a stream. The system also qualifies as linear so its temporary impacts to a wetland buffer are authorized by the criterion above. RMC 4-3-090(E)(11)(a)(vi): Utilities shall be located in existing rights-of-way and corridors, whenever reasonably feasible. 8. Most of the project would occur within the rights-of-way of SW 7`" St and. Naches Ave with a short segment (approximately 50 linear feet) within an undeveloped City owned parcel (Parcel #9188000154) on the west side of Naches Ave SW.

As determined in FOP No. 5, the proposal will not adversely affect any natural resources, including adjacent water courses and shorelines. RMC 4-3-090(E)(11)(b)(i i): Water quality is not to be degraded to the detriment of aquatic life nor shall water quality standards be violated_ 10. As determined in FOF No. 5, the proposal will not create any significant adverse water quality impacts and will in fact be improved by the proposal. RMC 4-3-090(E)(11)(c)(iii): All pipeline utilities shall be underground. When underground projects are completed on the bank of a water body or in the shoreland or a shoreline, the disturbed area shall be restored to the original conjiguration. Underground utility installations shall be permitted only when the finished installation shall not impair the appearance of such areas_ 11. The proposed storm drain would be installed underground adjacent to the existing storm system. No work would occur within the wetland /shoreline area_ SHORELINE CONDITIONAL USE CRITERIA 4-3-19001: The use must be compatible with other permitted uses within that area. 12. As determined in FOF No_ 5, the proposal is compatible with other permitted uses in the area. 4-3-190(1): The use will not interfere with the public use of public shorelines. 13. The utility lines will be underground and so will not interfere with public use of the shorelines. 4-3-190(X): Design of the site will be compatible with the surroundings and the Shoreline Master Program- ' The conditional use criteria were taken from the staff report, as the on-line version of the Renton Municipal Code does not appear to currently include the criteria. SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS R 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 is 19 20 21 22 23 24 25 26 14. As determined in FOF No. S, the proposal is compatible with the surroundings. The project will involve a temporary clearing of a wetland buffer, but required mitigation involves re -vegetation. The proposal is compatible with the Shoreline Master Program since it complies with all applicable regulations and policies as addressed in this decision. 4-3-190(1): The use shall be in harmony with the general purpose and intent of the Shoreline Master Program. 15. The general purpose of the City's Shoreline Master Program is to manage the shoreline for long term benefit preserving ecology and natural character and increasing recreational opportunities and public access. While the proposal would have no impact on the recreational opportunities and public access the proposal would improve water quality in the Black River drainage basin, improve conveyance at the South Renton basin, and reduce flooding at the Hardie Ave underpass. The project would also maintain the natural drainage course. As a result the proposed project would be in hannoony with the general purpose and intent of the Shoreline Master Program. 4-3-190(1): The use meets the conditional use criteria in WAC 173-27-160: 1. Uses which are classified or set forth in the applicable master program as conditional uses may be authorized provided that the applicant demonstrates all of the following: (a) That the proposed use is consistent with the policies of RCW 90.58.020 and the master program; (b) That the proposed use will not interfere with the normal public use of public shorelines; (c) That the proposed use of the site and design of the project is compatible with other authorized uses within the area and with uses planned for the area under the comprehensive plan and shoreline master program; (d) That the proposed use will cause no significant adverse effects to the shoreline environment in which it is to be located; and (e) That the public interest suffers no substantial detrimental effect_ 2. 7n the granting of all conditional use permits, consideration shall be given to the cumulative impact of additional requests for like actions in the area. For example, if conditional use permits were granted for other developments in the area where similar circumstances exist, the total of the conditional uses shall also remain consistent with the policies of RCW 90.58.020 and shall not produce substantial adverse effects to the shoreline environment. 16. As previously concluded, the proposal is consistent with the. policies of the Shoreline Management Act, will not interfere with normal public use of the shorelines and is compatible with other authorized shoreline uses. As determined in FOF No. 5, the proposal will not create any significant adverse impacts while overall improving water quality so the public interest will suffer no substantial detrimental effect. The impacts of the proposal are sufficiently minimal and the overall impacts are positive such that there are no associated adverse cumulative impacts.

The mitigation recommended in the Herrera report was prepared by a qualified professional and was accepted by staff. The recommended mitigation adequate mitigates wetland impacts and is imposed through the MDNS. B_ Stream_ An unnamed tributary to the Black River (Stream A) is also located within the project area. A Stream Study was submitted by the applicant, prepared by Herrera on May 24, 2013 (Exhibit 6). The stream was classified as a Class 2 stream with a 100 -foot buffer. The existing 60 -inch storm drain connects directly to Stream A within the culvert crossing of Naches Ave SW. The new 60 -inch storm drain will outfall adjacent to the existing culvert outlet. The stream at this location is currently armored with rock. A temporary stream bypass will be necessary to construct the outlet. Since the buffer of Stream A overlaps with the buffer of Wetland A, buffer impacts and consequent performance standards are included in the Wetland Assessment Report and Buffer Mitigation Plan (Exhibit 4). The Muckleshoot Tribe submitted written comment expressing concern over an increase in stream velocity that would be caused by the new outfall location into the stream. That increased velocity could adversely affect protected fish. In response to this concern staff added mitigation requiring the addition of large woody debris to the stream. Staff and the Tribe found this additional mitigation to adequately address velocity impacts and the mitigation is imposed through the MDNS. The tribe also suggested the use of alternative vegetation for the required planting plan and the applicant has agreed to consider it. C. No Net Lass of Ecological Function. The proposal will not crate any net loss of ecological shoreline function. The project includes temporary impacts to the buffer of Wetland A amounting to an approximately 700 square foot area of vegetation clearing. The Wetland Assessment Report and Buffer Mitigation Plan contains a buffer mitigation and vegetation management plan for the re -vegetation of cleared areas (Exhibit 4). The plan includes approaches for no net loss of ecological functions and for mitigation sequencing. Proposed performance standards are described to compensate for unavoidable temporary impacts to buffers. There are provisions for re -vegetating cleared areas with native plant SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 3 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 species and removing invasive plant species. The applicant is proposing to plant Douglas fir and black cottonwood trees, snowberry and beaked hazelnut shrubs, and sword fern_ The maintenance and monitoring program is proposed for a minimum of five years to ensure adequate establishment of installed vegetation and adequate cover of native vegetation and trees. A mitigation measure, as part of the SEPA determination, was issued requiring the submittal of a detailed final mitigation plan (Exhibit 13). The final mitigation plan will be required to be reviewed and approved by the Current Planning Project Manager, prior to the approval of construction permits. Conclusions of Law 1. Authority- RMC 4-8-080(G) classifies shoreline substantial development permits as Type II applications and shoreline conditional use permits as Type III applications_ RMC 4-8-080(0)(2) requires consolidated pen -nits to each be processed under "the highest -number procedure". The shoreline variance has the highest numbered review procedure, so both shoreline permits must be processed as Type III applications. As Type III applications, RMC 4-8-080(G) grants the Examiner with the authority to hold a hearing and issue a final decision on them, subject to closed record appeal to the City Council. 2. Shoreline Designations. Natural. 3. Review Criteria. RMC 4-3-090(E)(1) requires shoreline conditional use permits for structures for floodway management, including drainage facilities. Conditional use criteria are governed by RMC 4-9-030(D). The criteria for shoreline substantial development permits are set by RMC 4-9-190(B)(7), which requires compliance with all SMP use regulations and substantial compliance with SMP policies. All applicable criteria are quoted below in italics and applied through corresponding conclusions of law. The staff report analysis of compliance with RMC 4- 3.090(D) is adopted and incorporated by this reference as if set forth in full. SMF Policies SMP Objective U -F: Provide and maintain surface water management systems to minimize impacts on natural systems and to protect the public, property, surface water bodies, fish habitat, and groundwater from changes in the quantity and quality of storm water runoff due to land use changes. 4. As determined in FOF No. 5, as mitigated the proposal will not adversely affect stream or wetlands and those are the only natural systems potentially affected by the proposal_ No impacts to public property are anticipated since the proposal will be primarily located. underground_ SHORELINE SUBSTANTIAL DEVELOPMENT AND CONDITIONAL USE PERMITS 4 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 SMP Policy SH -6: Shoreline use and development should be carried out in a manner that prevents or mitigates adverse impacts so that the resulting ecological condition does not become worse than the current condition, This means ensuring no net loss of ecological functions and processes in all development and use. Permitted uses should he designed and conducted to minimize, in so far as practical, any resultant damage to the ecology and environment (RCW 90.58.020). Shoreline ecological f inctions that should be protected include, but are not limited to, fish and wildlife habitat, food chain support, and water temperature maintenance. Shoreline processes that shall be protected include, but are not limited to, water flow; littoral drift; erosion and accretion, infiltration; ground water recharge and discharge; sediment delivery, transport, and storage; large woody debris recruitment; organic matter input,- nutrient and pathogen removal; and stream channel formation/maintenance. 5. As determined in )~OF No. 5, the only ecological systems potentially affected by the proposal are wetlands and streams and no adverse impacts arc anticipated as to those resources. As further determined in FOF No. 5, the proposal will not result in any net loss of ecological function. RMC 4-3-090(E)(11)(a)(i): Local utility services needed to serve water -dependent and other permitted uses in the shoreline are subject to standards for ecological protection and visual compatibility. 6. As determined in FOF No. 5, the proposal will not create any adverse ecological or visual impacts_ RMC 4-3-090(E)(11)(a)(ii): Major utility systems shall be located outside of shoreline jurisdiction, to the extent feasible, except for elements that are water -dependent and crossings of water bodies and other elements of shorelands by linear facilities. 7. The proposal cannot be placed outside the shoreline jurisdiction since it involves the relocation of an existing water dependent storm water system that discharges into a stream. The system also qualifies as linear so its temporary impacts to a wetland buffer are authorized by the criterion above. RMC 4-3-090(E)(11)(a)(vi): Utilities shall be located in existing rights-of-way and corridors, whenever reasonably feasible. 8. Most of the project would occur within the rights-of-way of SW 7`h St and Naches Ave with a short segment (approximately 50 linear feet) within an undeveloped City owned parcel (Parcel #9188000154) on the west side of Naches Ave SW.

RMC 4-3-090(E)(11)(c)(iii): All pipeline utilities shall be underground. When underground projects are completed on the bank of a water body or in the shoreland or a shoreline, the disturbed area shall be restored to the original configuration. Underground utility installations shall be permitted only when the finished installation shall not impair the appearance of such areas_ 11. The proposed storm drain would be installed underground adjacent to the existing storm system_ No work would occur within the wetland /shoreline area. SHORELINE CONDITIONAL USE CRITERIA 4-3-190(1)1: The use must be compatible with other permitted uses within that area. 12. As determined in FOF No. 5, the proposal is compatible with other permitted uses in the area. 4-3-190(I): The use will not interfere with the public use of puhlic shorelines. 13. The utility lines will be underground and so will not interfere with public use of the shorelines. 4-3-190(I): Design of the site will be compatible with the surroundings and the Shoreline Master Program. The conditional use criteria were taken from the staff report, as the on-line version of the Renton Municipal Code does not appear to currently include the criteria.

The general purpose of the City's Shoreline Master Program is to manage the shoreline for long term benefit preserving ecology and natural character and increasing recreational opportunities and public access. While the proposal would have no impact on the recreational opportunities and public access the proposal would improve water quality in the Black River drainage basin, improve conveyance at the South Renton basin, and reduce flooding at the Hardie Ave underpass. The project would also maintain the natural drainage course. As a result the proposed project would be in harmony with the general purpose and intent of the Shoreline Master Program. 4-3-190(I): The use meets the conditional use criteria in WAC 173-27-160_ 1. Uses which are classified or set forth in the applicable master program as conditional uses may be authorized provided that the applicant demonstrates all of'the.following: (a) That the proposed use is consistent with the policies of RCW 90.58.020 and the master program; (b) That the proposed use will not interfere with the normal public use of public shorelines; (c) That the proposed use of the site and design of the project is compatible with other authorized uses within the area and with uses planned for the area under the comprehensive plan and shoreline master program; (d) That the proposed use will cause no significant adverse effects to the shoreline environment in which it is to be located; and (e) That the public interest suffers no substantial detrimental effect. 2. In the granting of all conditional use permits, consideration shall be given to the cumulative impact of additional requests for like actions in the area. For example, if conditional use permits were granted .for other developments in the area where similar circumstances exist, the total of the conditional uses shall also remain consistent with the policies of RCW 90.58.020 and shall not produce substantial adverse effects to the shoreline environment. 16. As previously concluded, the proposal is consistent with the policies of the Shoreline Management Act, will not interfere with normal public use of the shorelines and is compatible with other authorized shoreline uses. As determined in FOF No. 5, the proposal will not create any significant adverse impacts while overall improving water quality so the public interest will suffer no substantial detrimental effect. The impacts of the proposal are sufficiently minimal and the overall impacts are positive such that there are no associated adverse cumulative impacts.

The applicant is requesting SEPA Environmental Review, a Shoreline Substantial Development Permit, and a Shoreline Conditional Use Permit for the improvement of the stormwater conveyance capacity in the lower SW 7th St storm drainage system by installing an additional storm system pipe. 2. The Planning Division of the City of Renton received the above master application for review June 19, 2013 and the application was determined complete on July 14, 2013. The project complies with the 120 -day review period. 3. The existing SW 7`h St storm drainage system is a major trunk line draining 623 acres of the South Renton subbasin. 4. The existing pipe generally consists of 48 -inch to 60 -inch diameter pipe that extends west along SW 7th St and then north along Naches Ave SW where it discharges into an unnamed stream (Stream A). This stream drains to the Black River Pump Station. 5. The proposed improvement project is intended to alleviate recurrent flooding problems. In particular, at Hardie Ave SW near the Burlington Northern Santa Fe (BNSF) railroad trestle underpass; SW 7th St and Shattuck Ave; and in the vicinity of Rainier Ave S and SW Sunset Blvd. 6. The project site is primarily located within the public right-of-way. The portion of the project area west of Powell Ave SW is zoned Commercial Office (CO). The eastern portion of the project area is zoned Medium Industrial (1M). 7. Specific improvements of the project include approximately 3,330 lineal feet of 60 -inch diameter pipe that would be installed parallel to the existing system from its current outfall at Naches Ave SW to approximately Lind Ave SW. 8. Most of the project would occur within the rights-of-way of SW 7th St and Naches Ave with a short segment (approximately 50 linear feet) within an undeveloped City owned parcel (Parcel #9188000154) on the west side of Naches Ave SW. 9. The project would also require construction of an additional stormwater outfall in Stream A that runs east to west on the northern boundary of the City owned property. HEX Report City of Renton Department of Com ty & Economic Development Hearing Examiner Recommendation SW 7TH STREET/NACRES AVE SW STORM SYSTEM IMPROVEMENT PROJECT LUA13-000800, ECF, SMC, SM Report of September 10, 2013 Page 4 of 12 10. The project would also include the retrofit of the drainage condition along SW 7th St by installing 30-40 Filterra Systems along SW 7th St from Naches Ave SW to Lind Ave SW within the City rights-of-way. The Filterra systems would be designed to provide enhanced basic water quality treatment. 11. Topographically, the site can best be characterized as flat. Low slopes occur throughout most of the project area. Excluding drainage channels and streams the maximum relief across the site is 6 feet. The steepest slope is approximately 45% and is located on the bank of Stream A on the City -owned parcel where the new outfall would be located. 12. The area of impact would be approximately 270,000 square feet. The pipe depths would range from approximately 8 to 11 feet. The proposed project does not include any new impervious surfaces. 13. A Wetland Assessment Report and Buffer Mitigation Plan was submitted by the applicant, prepared by Herrera on May 24, 2013 (Exhibit 4). Hererra biologists delineated two wetlands within the project area; Wetlands A and B. The report contains a buffer mitigation and vegetation management plan for the re-vegetation of cleared areas. 14. Wetland A, a Catergory 1 wetland, is a large palustrine forested depressional wetland complex that is contiguous with the Black River Riparian Forest which is subject to the Renton Shoreline Master Program (RMC4-3-090). 15. Wetland B, a Category 3 wetland, is a pal ustrine forested wetland that occupies the southern portion of the City-owned parcel and is also subject to the Renton Shoreline Master Program (Exhibit 10). 16. No work would occur within the wetland /shoreline area and would occur within the wetland buffer. 17. The project includes temporary impacts to the buffer of Wetland A amounting to an approximately 700 square foot area of vegetation clearing. 18. An unnamed tributary to the Black River (Stream A) is also located within the project area. A Stream Study was submitted by the applicant, prepared by Herrera on May 24, 2013 (Exhibit 6). The stream was classified as a Class 2 stream with a 100-foot buffer. The existing 60-inch storm drain connects directly to Stream A within the culvert crossing of Naches Ave SW. The new 60-inch storm drain will outfall adjacent to the existing culvert outlet. The stream at this location is currently armored with rock. A temporary stream bypass will be necessary to construct the outlet. Since the buffer of Stream A overlaps with the buffer of Wetland A, buffer impacts and consequent performance standards are included in the Wetland Assessment Report and Buffer Mitigation Plan (Exhibit 4). 19. The project area is located in a wildlife conservation area associated with the Black River Riparian Forest. The applicant submitted Habitat Data Report, prepared by Herrera, dated May 24, 2013 (Exhibit 5) with the application. The project would affect fish and wildlife habitat conservation areas. The buffer mitigation and vegetation management plan, provided in the Wetland Assessment Report (Exhibit 4) presents a proposed approach for mitigation requirements for impacts to critical habitats. 20. The City-owned parcel lies almost completely within the 100 year floodplain, with the Black River riparian Forest (to the north and west of the project area) also occupying the 100-year flood plain. However, the proposed project areas are not located within the 100-year floodplain. 21. Construction is expected to begin in Spring of 2014 and be complete by June 2015. 22. Staff received comments from the Muckleshoot Tribe (Exhibit S) related to potential impacts to the habitat from increased stormwater volumes/velocities; the support of use of the Filterra Systems; and suggestions for alternative vegetation for the mitigation planting plan. 23. No other public or agency comments were received.

Use Criteria For All Utilities: Per RMC 4-3-090E.11 the proposal would be required to comply with the following use criteria for all utilities within the Shoreline Management area: N/A Local utility services needed to serve water -dependent and other permitted uses in the shoreline are subject to standards for ecological protection and visual compatibility. Major utility systems shall be located outside of shoreline jurisdiction, to the extent feasible, except for elements that are water -dependent and crossings of water bodies and other elements of shorelands by linear facilities. Staff Comment: No work would occur within the wetland /shoreline area and would occur within the wetland buffer only. The project includes temporary impacts to the buffer of Wetland A amounting to an approximate 700 square foot area of vegetation clearing. New public or private utilities shall be located inland from the land/water interface, preferably out of shoreline jurisdiction, unless: N/A (a) Perpendicular water crossings are unavoidable; or (b) Utilities are necessary for authorized shoreline uses consistent with the Shoreline Master Program. Linear facilities consisting of pipelines, cables and other facilities on land running roughly N/A parallel to the shoreline shall be located as far from the water's edge as feasible and preferably outside of shoreline jurisdiction. Linear facilities consisting of pipelines, sewers, cables and other facilities on aquatic lands running roughly parallel to the shoreline that may require periodic maintenance that would N/A disrupt shoreline ecological functions shall be discouraged except where no other feasible alternative exists. When permitted, provisions shall assure that the facilities do not result in a net loss of shoreline ecological functions or significant impacts to other shoreline resources and values. Utilities shall be located in existing rights-of-way and corridors, whenever reasonably feasible. Staff Comment: Specific improvements of the project include approximately 3,330 lineal feet of 60 -inch diameter pipe that would be installed parallel to the existing system from its current outfall at Naches Ave SW to approximately Lind Ave SW. Most of the project would occur within the rights-of-way of SW 7`" St and Naches Ave with a short segment (approximately 50linearfeet) within on undeveloped City owned parcel (Parcel #9188000154) on the west side of Naches Ave SW. N/A Local service utilities serving new development shall be located underground, wherever reasonably feasible. Utility crossings of water bodies shall be attached to bridges or located in other existing facilities, if reasonably feasible. If new installations are required to cross water bodies or wetlands they should avoid disturbing banks and streambeds and shall be designed to avoid N/A the need for shoreline stabilization. Crossings shall be tunneled or bored where reasonably feasible. Installations shall be deep enough to avoid failures or need for protection due to exposure due to streambed mobilization, aggregation or lateral migration. Underwater utilities shall be placed in a sleeve if reasonably feasible to avoid the need for excavation in the event of the need for maintenance or replacement.

All pipeline utilities shall be underground. When underground projects are completed on the bank of a water body or in the shoreland or a shoreline, the disturbed area shall be restored to the original configuration. Underground utility installations shall be permitted only when the finished installation shall not impair the appearance of such areas. Staff Comment: The proposed storm drain would be installed underground adjacent to the existing storm system. No work would occur within the wetland /shoreline area. 2. Shoreline Conditional Use Permit Criteria: Per RMC 4-3-190.1.5 the objective of a conditional use provision is to provide more control and flexibility for implementing the regulations of the Shoreline Master Program. With provisions to control undesirable effects, the scope of uses can be expanded to include many uses. Uses classified as conditional uses can be permitted only after consideration and by meeting such performance Standards that make the use compatible with other permitted uses within that area. A conditional use permit may be granted subject to the Administrator of the Department of Economic Development or designee determining compliance with each of the following conditions The use must be compatible with other permitted uses within that area. Staff Comment: The project is located within the public right-of-way. Surrounding land uses include both commercial and industrial properties. The proposed storm drain, to be installed adjacent to the existing storm system would not alter the existing land uses in the area and has already proven to be compatible. The use will not interfere with the public use of public shorelines. Staff Comment: The proposed storm drain and outfall would be located underground and would not impede public use of public shorelines. Design of the site will be compatible with the surroundings and the Shoreline Master Program. Staff Comment: No work would occur within the wetland /shoreline area and would occur within the wetland buffer. The project includes temporary impacts to the buffer of Wetland A amounting to an approximate 700 square foot area of vegetation clearing. This would include the removal of six red alder and willow trees that are between 8- and 12 -inches, and shrubs. Areas disturbed by project activities would be re -vegetated following construction. The applicant is proposing to plant Douglas fir and black cottonwood trees, snowberry and beaked hazelnut shrubs, and sword fern. The proposal would not alter the surroundings of the subject site. See additional findings below for a demonstration of compliance with Development Standards of the Shoreline Master Program. The use shall be in harmony with the general purpose and intent of the Shoreline Master Program. Staff Comment: The general purpose of the City's Shoreline Master Program is to manage the shoreline for long term benefit preserving ecology and natural character and increasing recreational opportunities and public access. While the proposal would have no impact on the recreational opportunities and public access the proposal would improve water quality in the Black River Forebay, improve conveyance at the South Renton basin, and reduce flooding at the Hardie Ave underpass. The project would also maintain the natural drainage course. As a result the proposed project would be in harmony with the general purpose and intent of the Shoreline Master Program.

Building and Development Location — Shoreline Orientation. N/A Shoreline developments shall locate the water -dependent, water -related, and water - enjoyment portions of their developments along the shoreline. 5. Archaeological, Historical, and Cultural Resources. Owners of property containing identified or probable historical, cultural, or archaeological sites are encouraged to coordinate well in advance of application for development to assure that appropriate agencies such as the Washington State Department of Archaeology and Historic Preservation, affected tribes, and historic preservation groups have ample time to assess the site and identify the potential for cultural resources. Staff Comment: !None of the Tribes contacted by letter responded to a solicitation to provide information on possible traditional cultural properties in the project area. However, it is possible that archaeological artifacts or a historic site could be encountered during project construction. This is due to the site's proximity to former archaeological discoveries. ✓ However, the likelihood of the project area containing cultural deposits is low because of prior ground disturbance activities to create the existing roadway. Should evidence of a historic site be found during site development, work shall immediately cease and the Washington State Department of Archaeology and Historic Preservation shall be contacted at (360) 586-3065. A survey shall be submitted that conforms to the requirements and standards of the Washington State Department of Archaeology and Historic Preservation and must be conducted under the on-site supervision of a state - approved archaeologist.

Rights reserved or otherwise held by Indian Tribes pursuant to treaties, executive orders, or statutes, including right to hunt, fish, gather, and the right to reserved water, shall not be impaired or limited by any action taken or authorized by the City under its Shoreline Master Program, and all rights shall be accommodated. 5Loft Comment: Staff received comments from the Muckleshoot Tribe (Exhibit 8) related to potential impacts to the habitat from increased stormwater volumes/velocities; the support of use of the Filterro Systems; and suggestions for alternative vegetation for the mitigation planting plan. Based on the suggestions from the Muckleshoot Tribes (Exhibit S) the applicant agreed to look at alternatives to Douglas fir for re -vegetation due to the hydrology of the area. With respect to potential impacts to habitat supplemental information'was received by the applicant. The proposed project would not result in increased runoff volumes to Stream A; however, it would result in some level of increased peak flows and corresponding increase of in -stream velocities. An accurate estimate of these increases had not been examined. During periods of peak storm water discharge, it was recognized that velocities are high in the Stream A reach west of Naches Avenue SW. Linder existing and proposed conditions, the applicant expects that instream velocities resulting from peak discharges likely exceed the optimum velocities for juvenile salmonids that are rearing in Stream A. During these times, the applicant expects that juvenile salmonids move to slower velocity waters outside of the main flow including backwaters, flooded bench habitat near the edges of the channel, and downstream reaches where flows have dissipated. This anticipated displacement of juveniles represents short-term impacts to rearing activity which could include unnecessary expenditures of energy, loss of feeding opportunity, vulnerability to predation, etc. Additional information was compiled to evaluate juvenile salmonid habitat conditions in Stream A west of Naches Avenue SW including results of a habitat survey conducted on August 9, 2013 (Exhibit 11). The reach of Stream A surveyed contains approximately 9 pieces of large woody debris per 100 meters. According to reference conditions, the median quantity of large woody debris is 52 pieces per 100 meters for streams in the range of 6 to 30 meters bankfull width. To address a lack of large woody debris, the applicant is proposing to add 6 pieces of large woody debris with attached root wads to a channel reach extending approximately 100 feet west of Naches Avenue SW. A mitigation measure was issued as part of the SEPA Determination (Exhibit 13) requiring the applicant provide a revised mitigation plan including the additional large woody debris. The revised, and detailed, mitigation plan shall be submitted to and approved by the Current Planning Project Manager prior to construction permit approval. H. CONCLUSIONS: I. The review of the application was based on the following: the application; the environmental checklist provided; information and comments from all affected City departments and is determined to be consistent with the policy and provisions of the Shoreline Management Act and the Shoreline Master Program. 2. The application is compliant with Shoreline Conditional Use Permit criteria listed in RMC 4-3-090. 3. The proposal does not degrade the ecological functions or natural character of the shoreline area.

We appreciate the City send all of these materials as they facilitated our review. We have some questions and initial comments about the project as noted below: The reports we have reviewed do not consider any potential impacts to Stream A from the discharge of additional peak flows. The Stream Study notes that there is existing salmon rearing habitat in Stream A, however, the study fails to analysis potential impacts to this habitat from increased stormwater volumes or velocities. Even with stormwater facilities that meet stormwater flow control duration standards; these facilities do not necessarily mitigate for increases in runoff volumes and stream velocities for fish and other aquatic biota. These impacts include displacement from preferred habitats; loss of feeding opportunities; increased stress and disease; increased predation, etc. The project needs additional information and analysis to demonstrate that the increases in peak flows (or increases in flow durations) do not adversely impact juvenile salmonids in Stream A. because stormwater discharged from the project site has the potential to increase the duration of water velocities in the receiving water that exceed juvenile resting, holding, and swimming speeds. A starting place is to provide all of the existing stream habitat data, including all of the available wood in -channel for Stream A to determine the extent of existing rearing habitat which can be compared against reference stream conditions. 2. From -the description of the existing pond downstream of the Naches Avenue culvert on Stream A (shown in Figure 2 of the Stream Study), it is described (on page 13) as having banks 10-15 feet higher than the surface water elevation of the stream and are highly erosive. Was this pond a constructed feature or is it the result of stormwater? 3. The project's approach to complete a stormwater quality retrofit using Filterra systems is good and should improve stormwater water quality discharged to Stream A over existing conditions. 4. The proposed planting of Douglas Fir trees in the wetland buffer mitigation areas may not be the best native trees species as these trees prefer drier sites. It may be better to replace them with Western hemlock or Western Red Cedar which prefer moist and wetter soil conditions. We appreciate the opportunity to review this proposal and look forward to the City's responses. We may have further comments subsequently.

The existing SW 7th St storm drainage system is a major trunk line draining 623 acres of the South Renton subbasin. The existing pipe generally consists of 48 -inch to 60 -inch diameter pipe that extends west along SW 7th St and then north along Naches Ave SW where it discharges into an unnamed stream (Stream A). This stream drains to the Black River Pump Station. The proposed improvement project is intended to alleviate recurrent flooding problems. In particular, at Hardie Ave SW near the Burlington Northern Santa Fe (BNSF) railroad trestle underpass; SW 7th St and Shattuck Ave; and in the vicinity of Rainier Ave S and SW Sunset Blvd. The project site is primarily located within the public right-of-way. The portion of the project area west of Powell Ave SW is zoned Commercial Office (CO). The eastern portion of the project area is zoned Medium Industrial (IM). Specific improvements of the project include approximately 3,330 lineal feet of 60 -inch diameter pipe that would be installed parallel to the existing system from its current outfall at Naches Ave SW to approximately Lind Ave SW. Most of the project would occur within the rights-of-way of SW 7th St and Naches Ave with a short segment (approximately 50 linear feet) within an undeveloped City owned parcel (Parcel #9188000154) on the west side of Naches Ave 5W. The project would also require construction of an additional stormwater outfall in Stream A that runs east to west on the northern boundary of the City owned property. Finally, the project would also include the retrofit of the drainage condition along SW 7th St by installing 30-40 Filterra Systems along SW 7th St from Naches Ave SW to Lind Ave SW within the City rights-of-way. The Filterra systems would be designed to provide enhanced basic water quality treatment. The area of impact would be approximately 270,000 square feet. The pipe depths would range from approximately 8 to 11 feet. The proposed project does not include any new impervious surfaces. A Wetland Assessment Report and Buffer Mitigation Plan was submitted by the applicant, prepared by Herrera on May 24, 2013 (Exhibit 4). Hererra biologists delineated two wetlands within the project area; Wetlands A and B. Wetland A, a Catergory 1 wetland, is a large palustrine forested depressional wetland complex that is contiguous with the Black River Riparian Forest which is subject to the Renton Shoreline Master Program (RMC4-3-090). Wetland B, a Category 3 wetland, is a palustrine forested wetland that occupies the southern portion of the City -owned parcel and is also subject to the Renton Shoreline Master Program (Exhibit 10). No work will occur within the wetland /shoreline area. The project includes temporary impacts to the buffer of Wetland A amounting to an approximately 700 square foot area of vegetation clearing. The report contains a buffer mitigation and vegetation management plan for the re -vegetation of cleared areas. An unnamed tributary to the Black River (Stream A) is also located within the project area. A Stream Study was submitted by the applicant, prepared by Herrera on May 24, 2013 (Exhibit 6). The stream was ERC Reporl City of Renton Department of Communi' - Economic Development F ' onmental Review Committee Report SW 7TH STREETINACHES AVE SW STOI YSTFM IMPROVEMENT PROJECT LUA13-000800, ECF, SM, SMC Report of August 19, 2013 Page 3 of 11 classified as a Class 2 stream with a 100 -foot buffer. The existing 60 -inch storm drain connects directly to Stream A within the culvert crossing of Naches Ave SW. The new 60 -inch storm drain will outfall adjacent to the existing culvert outlet. The stream at this location is currently armored with rock. A temporary stream bypass will be necessary to construct the outlet. Since the buffer of Stream A overlaps with the buffer of Wetland A, buffer impacts and consequent mitigation measures are included in the Wetland Assessment Report and Buffer Mitigation Plan (Exhibit 4). The project area is located in a wildlife conservation area associated with the Black River Riparian Forest. The applicant submitted Habitat Data Report, prepared by Herrera, dated May 24, 2013 (Exhibit 5) with the application. The project would affect fish and wildlife habitat conservation areas. The buffer mitigation and vegetation management plan, provided in the Wetland Assessment Report (Exhibit 4) presents a proposed approach for mitigation requirements for impacts to critical habitats. The City -owned parcel lies almost completely within the 100 year floodplain, with the Black River riparian Forest (to the north and west of the project area) also occupying the 100 -year flood plain. However, the proposed project areas are not located within the 100 -year floodplain. Staff received comments from the Muckleshoot Tribe (Exhibit 8) related to potential impacts to the habitat from increased stormwater volumes/velocities; the support of use of the Filterra Systems; and suggestions for alternative vegetation for the mitigation planting plan. Construction is expected to begin in Spring of 2014 and be complete by June 2015. PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Threshold Recommendation Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials: Issue a DNS -M with a 14 -day Appeal Period. B. Mitigation Measures 1. The applicant shall comply with the recommendations included in the Geotechnical Engineering Study prepared by HWA GeoSciences Inc., dated February 27, 2012. 2. The applicant shall be required to provide a detailed final mitigation and monitoring plan.

Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the fallowing probable impacts: 1. Earth Impacts: The site can best be characterized as flat. Low slopes occur throughout most of the project area. Excluding drainage channels and streams the maximum relief across the site is 6 feet. The steepest slope is approximately 45% and is located on the bank of Stream A on the City -owned parcel where the new outfall would be located. Approximately 14,355 cubic yards of material are being excavated for the stormwater installation. Approximately, 1.,250 cubic yards of material would be brought in to backfill the stormwater excavation. Additional materials, in the amount of 20 cubic yards, are being brought in for the installation of temporary cofferdams, topsoil in planting areas and mulch in planting areas. Approximately 95% of the site is currently covered with impervious surface, which would remain following construction. Impervious surface within the project area would however decrease slightly due to proposed Filterra systems.

The report included geotechnical considerations when evaluating the proposed alignment. The investigation included the drilling of eight exploratory boreholes extended to depths of 30 feet below ground surface. The storm drain alignments are underlain by a sequence of fill and alluvium. The fill was encountered directly beneath pavement in nearly all of the borings, extending to depths of approximately 2.5 to 7.5 feet. The fill encountered consisted generally of loose to medium dense, clean to slightly silty sand and gravel. Recent alluvium was encountered in all of the explorations immediately below the fill and extended the entire depth of the explorations. The alluvium consisted of interbedded, very loose to medium dense, clean to very silty sand, and very soft to medium stiff, dark, organic silt, peat, and silt. Ground water was encountered in all borings during drilling at depths varying from approximately 4 to 14 feet below ground surface, with most ground water levels in the vicinity of 7 to 10 feet below ground surface. HWA also evaluated the project alignments for the potential presence of contamination that may present issues during construction. Based on the subsurface conditions encountered in the geotechnical investigation the proposed pipeline will traverse loose, soft alluvial soils below the groundwater table and construction dewatering would be necessary. Based on geotechnical concerns recommendations in the report include seismic considerations, temporary shoring, dewatering, fill placement and materials considerations. Based on the recommendations included in the provided report, staff recommends as a mitigation measure that the applicant comply with the recommendations included in the provided Geotechnical Report prepared by HWA GeoSciences Inc., dated February 27, 2012. Mitigation Measures: The applicant shall comply with the recommendations included in the Geotechnical Engineering Study prepared by HWA GeoSciences Inc., dated February 27, 2012.

Wetland, Streams, Lakes Impacts: A Wetland Assessment Report and Buffer Mitigation Plan was submitted by the applicant, prepared by Herrera on May 24, 2013 (Exhibit 4). Hererra biologist delineated two wetlands within the project area; Wetlands A and B. Wetland A, a Catergory 1 wetland, is a large palustrine forested depressional wetland complex. Wetland A is located on the northern portion of the City - owned parcel. Wetland B, a Category 3 wetland, is a palustrine forested wetland that occupies the southern portion of the City -owned parcel. The boundary of the shoreline designation includes areas within 200 feet of the ordinary high water mark (OHWM) and contiguous wetlands and floodplains. Wetlands A and B are associated with the Black River Pump Station Forebay, a regulated shoreline, and therefore subject to the Shoreline Master Program. The wetlands are located within the Natural Environment Overlay District. An unnamed tributary to the Black River (Stream A) is also located within the project area which flows from east to west along the northern boundary of the City -owned parcel. A Stream Study was submitted by the applicant, prepared by Herrera on May 24, 2013 (Exhibit 6). The stream was classified as a Class 2 stream with a 100 -foot buffer. The stream originates upstream via culverts and flows into the Black River wetland system located within the Black River Riparian Forest. ERC Reporl City of Renton Department of Comm un Economic Development L onmental Review Committee Report SW 7TH STREET/NACHES AVE SW STORM SYSTEM IMPROVEMENT PROJECT LUA13-000800, ECF, SM, SMC Report of August 19, 2013 Page 6 of 11 The project includes temporary impacts to the buffer of Wetland A amounting to an approximately 700 square foot area of vegetation clearing. Under the Shoreline Master Program, a Shoreline Substantial Development Permit and a Shoreline Conditional Use Permit are needed for any activities done in the Natural Environment Overlay District. There is a no net loss requirement with the Natural Environment Overlay District. The report contains a buffer mitigation and vegetation management plan for the re -vegetation of cleared areas. Additionally, the existing 60 -inch storm drain connects directly to Stream A within the culvert crossing of Naches Ave SW. The new 60 -inch storm drain would outfall adjacent to the existing culvert outlet. Approximately 15 linear feet of the channel bed and south bank of the stream would be temporarily affected during installation of the outfall pipe. The stream at this location is currently armored with rock. A temporary stream bypass would be necessary to construct the outlet. The two temporary cofferdams would be used to direct flow into the stream bypass pipeline; approximately 7.5 cubic yards of material are needed for the installation. Since the buffer of Stream A overlaps with buffer of Wetland A, buffer impacts and consequent mitigation measures are included in the Wetland Assessment Report and Mitigation Plan (Exhibit 4). The wetlands are dominated by black cottonwood, Pacific willow, red alder, and Oregon ash; with an understory of Sitka willow, red osier dogwood, salmonberry, Douglas spirea, Pacific ninebark, Himalayan blackberry, lady fern, stinging nettle, creeping buttercup, slough sedge, and reed canary grass. The applicant has provided a conceptual mitigation plan (Exhibit 4). The plan includes approaches for no net loss of ecological functions and for mitigation sequencing. Proposed performance standards are described to compensate for unavoidable temporary impacts to buffers. There are provisions for re -vegetating cleared areas with native plant species and removing invasive plant species. The applicant is proposing to plant Douglas fir and black cottonwood trees, snowberry and beaked hazelnut shrubs, and sword fern. The maintenance and monitoring program is proposed for a minimum five years to ensure adequate establishment of installed vegetation and adequate cover of native vegetation and trees. A final mitigation plan will be needed for the proposed impacts to the buffer. Therefore, staff recommends a mitigation measure requiring a detailed final mitigation pian. The final mitigation plan shall be reviewed and approved by the Current Planning Project Manager, prior to the approval of construction permits. Mitigation Measures: The applicant shall be required to provide a detailed final mitigation and monitoring plan. The final mitigation and monitoring plan shall be reviewed and approved by the Current Planning Project Manager, prior to the approval of construction permits. Nexus: SEPA Environmental Regulations, Critical Areas Regulations b. Storm Water Impacts: The existing SW 7th St storm drainage system is a major trunk line draining 623 acres of the South Renton subbasin. The existing pipe generally consists of 48 -inch to 60 -inch diameter pipe that extends west along SW 7th St and then north along Naches Ave SW where it discharges to Stream A. The applicant submitted a Preliminary Drainage Memorandum (Exhibit 7) prepared by SAIC, dated October, 2012 with a 30% design concept. The objective of the conveyance improvements is to meet the City's design criteria for stormwater conveyance in accordance with the City's Amendments to the King County Surface Water Design Manual (2009). However, it is important to ERC Reporl City of Renton Department of Comm uni Economic Development F nmental Review Committee Report SW 7TH STREET/NACHES AVE S W STORM SYSTEM IMPROVEMENT PROJECT LUA13-000800, ECF, SM, SMC Report of August 14, 2013 Page 7 of 11 note that the design criteria were developed to guide sizing for new systems within new development and/or redevelopment projects. The proposed project is considered a system replacement/improvement to reduce flood hazards and not associated with new development. As a result, the project is not required to fully comply with the design requirements. Instead, the criteria is considered target criteria. The applicant would be required to provide a Final Drainage Analysis prior to construction permit approval. Mitigation Measures: No further mitigation needed. Nexus: Not applicable. 3. Vegetation Impacts. Approximately 700 square feet of upland forest vegetation would be cleared on the undeveloped City -owned parcel. This would include the removal of six red alder and willow trees that are between S- and 12 -inches, and shrubs. Areas disturbed by project activities would be re - vegetated following construction. The applicant is proposing to plant Douglas fir and black cottonwood trees, snowberry and beaked hazelnut shrubs, and sword fern. Based on the suggestions from the Muckleshoot Tribes (Exhibit S) the applicant agreed to look at alternatives to Douglas fir for re -vegetation due to the hydrology of the area. Mitigation Measures: No further mitigation required. Nexus: Not applicable. 4. Wildlife Impacts: Per RMC4-3-050K, Wetland A is considered a Critical Habitat due to the presence of the Category 1 wetland. The applicant has submitted a Habitat Data Report, prepared by Herrera, dated May 24, 2013 (Exhibit 5) with the application. The open water area of the Black River Riparian Forest, located approximately 1,200 feet west of the project site, is known to support local concentrations of migratory birds and waterfowl, and the Puget Sound region in general is within the Pacific Flyway for migratory birds. The Black River Riparian Forest supports a blue heron rookery/breeding area; however the protective buffer boundary is beyond the project site limits. The Black River Riparian Forest also contains a documented bald eagle nest but this mapped management buffer area does not extend into the project area. A variety of fish are documented as being present in the vicinity of the project area. Chinook salmon, coho salmon, steelhead trout, and coastal resident cutthroat trout are known to be present within the Black River system. Puget Sound Chinook salmon and Puget Sound steelhead trout are both listed as federally threatened under the Endangered Species Act. The portion of Stream A within the project area does not provide spawning habitat for fish but does provide moderate- to low -quality rearing and refuge habitat for fish. The proposed project would result in unavoidable impacts to the buffer of Wetland A and Stream A, which is also a Habitat Conservation Area. In order to maintain the functions and values of the habitat the applicant is proposing to retain as much of the native vegetation feasible and compensate for any impacts that may occur from project activities. Wetland and stream buffers and critical habitats within the project area overlap, therefore impacts to these areas and associated mitigation plans are described collectively in the in the Wetland Assessment Report and Buffer Mitigation Plan (Exhibit 4). Native plant species that would be FRC Reporl City of Renton Department of Communf Economic Development L onmental Review Committee Report SW 7TH STREET/NACHES AVE SW STORM SYSTEM IMPROVEMENT PROJECT [UA13-000800, ECF, SM, SMC Report of August 19, 2013 Page 8 of 11 installed as part of the project and large woody material retained onsite (from trees that need to be removed to install the stormwater pipe) would provide forage and cover for wildlife. Staff has received comments from the Muckleshoot Tribe (Exhibit 8) related to potential impacts to the habitat from increased stormwater volumes/velocities. Supplemental information was received by the applicant with respect to questions raised by the tribes. The proposed project would not result in increased runoff volumes to Stream A; however, it would result in some level of increased peak flows and corresponding increase of instream velocities. An accurate estimate of these increases has not been examined. During periods of peak storm water discharge, it is recognized that velocities are high in the Stream A reach west of Naches Avenue SW. Under existing and proposed conditions, the applicant expects that instream velocities resulting from peak discharges likely exceed the optimum velocities for juvenile salmonids that are rearing in Stream A. During these times, the applicant expects that juvenile salmonids move to slower velocity waters outside of the main flow including backwaters, flooded bench habitat near the edges of the channel, and downstream reaches where flows have dissipated. This anticipated displacement of juveniles represents short-term impacts to rearing activity which could include unnecessary expenditures of energy, loss of feeding opportunity, vulnerability to predation, etc. Additional information was compiled to evaluate juvenile salmonid habitat conditions in Stream A west of Naches Avenue SW including results of a habitat survey conducted on August 9, 2013 (Exhibit 11). The reach of Stream A surveyed contains approximately 9 pieces of large woody debris per 100 meters. According to reference conditions, the median quantity of large woody debris is 52 pieces per 100 meters for streams in the range of 6 to 30 meters bankfull width. To address a lack of large woody debris, the applicant is proposing to add 6 pieces of large woody debris with attached root wads to a channel reach extending approximately 100 feet west of Naches Avenue SW. Staff recommends as a mitigation measure, the applicant provide a revised mitigation plan including the additional large woody debris. The revised, and detailed, mitigation plan shall be submitted to and approved by the Current Planning Project Manager prior to construction permit approval. Mitigation Measures: The applicant shall provide a revised mitigation plan including the additional large woody debris. The revised, and detailed, mitigation plan shall be submitted to and approved by the Current Planning Project Manager prior to construction permit approval. Nexus: SEPA Environmental Regulations, Critical Areas Regulations 5. Historic and Cultural Preservation Impacts: None of the Tribes contacted by letter responded to a solicitation to provide information on possible traditional cultural properties in the project area. It is possible that archaeological artifacts or a historic site could be encountered during project construction. This is due to the site's proximity to former archaeological discoveries. However, the likelihood of the project area containing cultural deposits is low because of prior ground disturbance activities to create the existing roadway. Should evidence of a historic site be found during site development, work shall immediately cease and the Washington State Department of Archaeology and Historic Preservation shall be contacted at (360) 586-3065.

Transportation Impacts, The proposed alignment for the new pipe along SW 7t" St ss primarily near the center of the road. The alignment is favorable because of the layout of existing utilities for most of the length, allowing the outer lanes to maintain 2 -way traffic as well as ingress/egress to private properties. Work at intersections would likely involve more traffic control and require detours. There are three existing railroad crossings along the alignment, all along SW 7th St. The railroad crossings are within City right-of-way. The applicant is planning on coordinating construction requirements with BNSF. The applicant contends and staff concurs that impacts related to traffic would be mitigated to the greatest extent possible through the application of traffic control plans, construction staging plans, and continual communication and coordination with businesses along the project limits as well as BNSF. Staff recommends, as a mitigation measure, the applicant be required to provide a final Traffic Control Plan, prior to construction permit approval, in order to ensure that adequate traffic control is provided during the construction phases and to help ensure access through the construction zone.

Nexus: SEPA Regulations, Construction Standards RMC 4-4-130.0 7. Utilities Impacts: Construction of a large diameter pipeline within a developed urban corridor is likely to require existing utilities to be relocated. These utilities include public utilities such as water and sewer lines. It is likely the corridor contains private utilities as well, such as gas, power, fiber optic, and telephone. Utility potholing was completed to help identify conflicts (Exhibit 7, Appendix D). Typically, private utilities operate within the City right-of-way under a franchise agreement. In accordance with the terms of the franchise agreement, these private utilities must relocate facilities if necessary to make room for City improvements. However, it is important to notify these private utilities of the required relocations prior to construction. Staff recommends, as a mitigation measure, the applicant be required to demonstrate attempted contact with all private utilities ERC Reporl City of Renton Department of Commune Economic Development + onmental Review Committee Report SW 7TH STREET/NACRES AVE SW STORM SYSTEM IMPROVEMENT PROJECT LUA13-000800, ECF, SM, SMC Report of August 19, 2013 Page 10 of 11 impacted by the project.

We appreciate the City send all of these materials as they facilitated our review. We have some questions and initial comments about the project as noted below: The reports we have reviewed do not consider any potential impacts to Stream A from the discharge of additional peak flows. The Stream Study notes that there is existing salmon rearing habitat in Stream A, however, the study fails to analysis potential impacts to this habitat from increased stormwater volumes or velocities. Even with stormwater facilities that meet stormwater flow control duration standards; these facilities do not necessarily mitigate for increases in runoff volumes and stream velocities for fish and other aquatic biota. These impacts include displacement from preferred habitats; loss of feeding opportunities; increased stress and disease; increased predation, etc. The project needs additional information and analysis to demonstrate that the increases in peak flows (or increases in flow durations) do not adversely impact juvenile salmonids in Stream A. because stormwater discharged from the project site has the potential to increase the duration of water velocities in the receiving water that exceed juvenile resting, holding, and swimming speeds. A starting place is to provide all of the existing stream habitat data, including all of the available wood in -channel for Stream A to determine the extent of existing rearing habitat which can be compared against reference stream conditions. 2. From the description of the existing pond downstream of the Naches Avenue culvert on Stream A (shown in Figure 2 of the Stream Study), it is described (on page 13) as having banks 10-15 feet higher than the surface water elevation of the stream and are highly erosive. Was this pond a constructed feature or is it the result of stormwater? 3. The project's approach to complete a stormwater quality retrofit using Filterra systems is good and should improve stormwater water quality discharged to Stream A over existing conditions. 4. The proposed planting of Douglas Fir trees in the wetland buffer mitigation areas may not be the best native trees species as these trees prefer drier sites. It may be better to replace them with Western hemlock or Western Red Cedar which prefer moist and wetter soil conditions. We appreciate the opportunity to review this proposal and look forward to the City's responses. We may have further comments subsequently.

The project will require construction of an additional stormwater outfall in the Stream A that runs from east to west on the northern boundary of the City -owned property. This project will also retrofit the drainage system along SW 7th St installing Filterra Systems along SW 7th St. from Naches Ave SW and Lind Ave SW to provide enhanced basic water quality treatment. The Filterra systems will be designed to provide enhanced basic water quality treatment. The total area for all drainage basins draining toward the project is approximately 623 acres. Site area impacted will be 270,000 sf. Of the entire project alignment, only 60 linear feet is located in the SMP Natural Environment; as such the project is subject the regulations of the SMP. Structures for Floodway Management, Including Drainage facilities require a Shoreline Conditional Use in the SMP Natural Environment, provided that the use does not degrade the ecological functions or natural character of the shoreline area. The Hardie Ave SW — SW 7th St. Storm System Improvement Project will be constructed to assure compliance with each of the following conditions. Condition #1: The use must be compatible with other permitted uses within that area. Response: The project is in public right-of-way. Current land uses of the adjacent areas are commercial and industrial. Proposed 60 -inch trunk storm drain to be installed parallel to the existing storm system from its current outfall at Naches Ave SW to approximately Lind Ave SW and will not change the land use of the area. Enhanced basic water quality treatment and oil treatment will be provided before discharging into the Black River. There is an existing stormwater outfall in Naches Ave SW. The proposed new outfall will be located in the City owned parcel (ID: 918800154). Proposed project qualifies as stormwater conveyance or discharge facilities as allowed in the City adopted Shoreline Master Program adopted in ordinance 5633. Many utilities currently exist in along SW 7th St between Naches Ave SW and Lind Ave SW. Project proposal will be compatible with other permitted uses within the area. Condition #2: The use will not interfere with the public use of public shorelines. Response: Project proposal is to install an underground 60 —inch storm system, a new outfall to the Black River and water quality treatment prior to discharge (Filterra systems along SW 7th St). The proposed project will remain within City owned parcel, and City right-of-way; and will continue to provide transportation for the City as it does today. Public access to the Shorelines will not be impaired. Condition #3: Design of the site will be compatible with the surroundings and the Shoreline Master Program. Project proposal to install a parallel 60 -inch diameter pipe along SW 7th St., construct a new outfall into the Black River and provide storm water quality treatment before discharging into the Black River and will not result in a change in the shoreline designation, therefore public access and use of the shoreline will not impaired. No work will occur within the wetland within the shoreline area. Work will only occur in the wetland buffer. The health, safety, and welfare of the public and shoreline will be preserved by the Conditional Use Permit for the Hardie Ave SW — SW 7th St. Storm System Improvement Project. Disturbed areas will be restored to pre - project condition. Condition #4: The use shall be in harmony with the general purpose and intent of the Shoreline Master Program. It is the general purpose of the City's Shoreline Master Program (adopted in accordance with the Washington State Shoreline Managemnet Act (SMA) to manage the shoreline for long term benefit by preserving ecology and natural character and increasing recreational opportunities and public access. Project proposal is to improve water quality in the Black River Forebay and ultimately the Green River, improve conveyance capacity at the South Renton basin; and reduce flooding at the Hardie underpass. The natural character of the shoreline, associated buffers will be preserve. Temporary impacts to the wetland buffer will be mitigated trough planting to pre -project condition. Public access will be maintained.

Give a brief, complete description of your proposal, including the proposed uses and the size of the project and site. The City of Renton proposes to improve stormwater conveyance capacity in the lower SW 7th Street trunk drainage system by installing an additional storm system pipe. The existing SW 7th Street storm drainage system is a major trunk line draining 623 acres of the South Renton Subbasin, which includes much of the downtown area. The existing pipe system generally consists of 48 -inch to 60 -inch diameter pipe that extends west along SW 7th Street and then north along Naches Ave SW where it discharges to an unnamed stream (Stream A). This stream drains to the Black River Pump Station forebay. Within the basin, there are recurrent flooding problems. In particular, at Hardie Avenue SW near the Burlington Northern Santa Fe (BNSF) railroad trestle underpass; SW 7th Street and Shattuck Avenue; and in the vicinity of Rainer Avenue and SW Sunset Boulevard. The purpose of this project is to construct a parallel storm drain in the lower portion of the basin to increase overall system capacity and help alleviate upstream flooding problems particularly at the Hardie underpass. The proposed sizing and alignment of the parallel pipe system was studied and recommended as part of a pre -design study (SAIL 2012). The specific improvements of the project include approximately 3,330 feet of 60 -inch diameter trunk storm drain that would be installed parallel to the existing system from its current outfall at Naches Ave SW to approximately Lind Ave SW. Most of the project would occur within the rights-of-way of SW 7th Street and Naches Avenue (approximately 3,280 feet in length), with a short segment (approximately 50 feet) being constructed on an undeveloped City -owned property (parcel ID: 9188000154) on the west side of Naches Avenue SW. The project will require construction of an additional stormwater outfall in the Stream A that runs from east to west on the northern boundary of the City -owned property. This project will also retrofit the drainage condition along SW 7th Street by installing Filterra Systems along SW 7th Street from Naches Ave SW and Lind Ave SW within City rights-of-way. The Filterra systems will be designed to provide enhanced basic water quality treatment. -4- W09 G:1UserslhbernardolAppDatalLocal\MicrosoRlWindowslTemporary Internet Files\Content.OutlooklHUgN7LYEISW 7th_SEPA_Final.doc The uses of the site will not change from their current uses: City streets will retain their transportation uses and the City -owned parcel will retain its natural open space use as a City of Renton Habitat Conservation Area. The entire project is approximately one acre in size, in a long, linear configuration (3,330 feet long and approximately 10 feet to 18 feet wide along the trunk line improvements and up to 30 feet wide where Filterra systems are installed). 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project will occur in the existing right-of-way along SW 7th Street (between Naches Ave SW and approximately Lind Ave SW) and Naches Ave SW and in an undeveloped City of Renton owned parcel (Parcel number 9188000154). The project is located in Sections 13, 24, 19, 18 of Townships 23N in Ranges 4E, 4E, 5E, and 5E, respectively, of the Willamette Meridian. A project area map and site plans for this project are provided in the attached Wetland Assessment Report and Buffer Mitigation Plan for the SW 7th Street/Naches Avenue SW Storm System Improvement Project (Herrera 2013), as well as aforementioned environmental documents prepared in support of this project.

AIR (BMPs). Descriptions of these are provided in the attached project plans and Wetland Assessment Report and Buffer Mitigotion Plan for the SW 7th Street%Naches Ave SW Storm System Improvement Project (Herrera 2013). These measures include: • Installation of a temporary stream -flow bypass system (cofferdams and 48 - inch pipe), to facilitate outfall construction in dry stream channel conditions Installation of silt fences • Covering of stockpiled soil • Replanting and mulching of disturbed areas following construction • Monitoring and maintenance of BMP's by the contractor according to the project plans and specifications • Minimizing the allowable disturbance area near the proposed outfall. 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. Dust could be released into the air during excavation activities; installation of backfill materials; and during transport of materials to and from the site. Operating diesel- and gasoline -powered construction equipment (water truck, road compactor, dump truck, excavator, cement/mortar mixers, graders, tractors/loaders/backhoes, front end loaders, generators) will also release exhaust emissions and odors into the air. After construction, the project will not generate emissions to the air. The following table provides a summary of the estimated emissions that would be released in the air as a result of constructing the project according to the Procedures Document for National Emissions Inventory, Criteria Air Pollutants, 1985-1999 (EPA 2001): "Type of Emission Pollutant Estimated Emission (tons/yr.)

Proposed measures to reduce or control emissions or other impacts to air, if a ny: The contractor will be required to implement standard Best Management Practices (BMPs) for the control of air emissions and fugitive dust. These BMPs will include: • Keep all paved surfaces within the project area clean to prevent the release of dust from the site • Remove dirt from trucks and other construction equipment before leaving the site to prevent loose material from being tracked onto local streets • Thoroughly clean the roadway surface each workday • Completely cover the beds of trucks transporting debris, gravel, soil, or other loose material to or from the site with tarps or other appropriate cover • Cover all stockpiles with plastic sheeting or other appropriate covering to control the release of dust • Keep diesel- and gasoline—powered construction equipment in good working order and fitted with appropriate muffler and exhaust systems • Minimize vehicle idling. 3. WATER a. Surface Water: 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. An unnamed stream (Stream A) flows from east to west along the northern boundary of the City -owned property at the west end of the project site. Stream A is tributary to the Black River approximately 800 feet downstream of the culvert at Naches Avenue SW. The Black River then flows into the Quwamish River at river mile (RM) 11.0. Stream A is designated as a Class 2 stream according to the City of Renton Municipal Code (RMC 4-3-050) because it is perennial and presumed to support salmonids. A complete description of Stream A is provided in the Wetland Assessment Report and Buffer Mitigation Plan for the SW 7`r' Street/Naches Ave SW Storm System Improvement Project (Herrera 2013). 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. The project will involve construction of a new pipeline outfall that will be located directly landward of the Stream A ordinary high water mark (OHMW). Approximately 15 linear feet of the channel bed and left (south) bank of Stream A will be temporarily affected during installation of the outfall pipe (streamflow bypass and bank excavation). Between Naches Avenue SW and the new outfall, - 8 - 06109 CaUserslhbernardo\Appaata\LccallMicrosoft\Windows\Temporary Internet FileslContent.Outlook\HU9N7LYElSW 7th SEPA Final.doc installation of the new stormwater pipe will require approximately 700 square feet of vegetation clearing in the buffer of Stream A and excavation of a trench. During construction of the outfall, two temporary cofferdams will be constructed to direct flow into a stream bypass pipeline. The bed and bank of Stream A will be restored to their pre-existing condition. The disturbed portion of the buffer will: be replanted with native shrubs and groundcover. These activities are described in detail in the Stream Study for the SW 7rh Street/Naches Ave SW Storm System Improvement Project (Herrera 2013). 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. The temporary cofferdams will be constructed of gravel -filled sandbags from a local source. The soil and rock to backfill the trench excavated for the stormwater pipe and outfall will be sourced from the excavated material at the site or will be obtained from a local source. The following table comprises a description of fill/excavation within Stream A, defined as below the ordinary high water mark (OHWM): 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. Yes, the proposal will require temporarily bypassing surface water from Stream A adjacent to the construction site through a 48 -inch diameter pipe, so that the project can be constructed in dry conditions. Cofferdams constructed of gravel - filled sandbags will be installed at the upstream and downstream limits of the temporary bypass pipe. While stream flow is bypassed, if ground water enters the construction area, the area may need to be dewatered. Any water that needs to be pumped from excavated areas is expected to be very low volume and will be dispersed into surrounding uplands. 5) Does the proposal lie within a 100 -year flood plain? If so, note location on the site plan. No, the proposal does not lie within a 100 -year floodplain. The location of nearby mapped floodplain areas is shown in the Stream Study for the SW 7 1 Street/Naches Ave SW Storm System Improvement Protect (Herrera 2013). 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. - 9 - 06109 C:lUserslhbernardoUAppQatalLocai\MicrosoftVWindowslTemporary Internet Fileslcontent.Outlook\HU9N7LYE\SW 7th SEPA Final.doc Approximate Amount of Area Directly Material Affected Type of Activity (cubic yards) (square feet) Temporary cofferdam installation 7.5 150 Excavation for stormwater system 14,340 33,000 installation Backfill for stormwater system 11,230 33,000 installation 4) Will the proposal require surface water withdrawals or diversions?

Filterra systems will be installed to remove pollutants from stormwater, thereby minimizing the release of pollutants in stormwater to Stream A. The new stormwater pipe will parallel an existing pipe. The anticipated volume of discharge will be the same as existing (66 million cubic feet per year); flow will be split between the two pipe systems. b. Ground Water: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. Groundwater may be encountered during stormwater system installation activities. Depending on the time of year, the contractor may need to use point wells to dewater trenches, otherwise it will be removed via sump pumping, treated with Baker tanks (if it does not meet State water quality standards), and then discharged to a storm drain or directly to the sewer system. 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 applicable), or the number of animals or humans the system(s) are expected to serve. Does not apply. C. Water Runoff (including storm water): 1) Describe the source of runoff (including storm water) 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. Runoff from stormwater during construction will be managed through implementation of the Temporary Erosion and Sediment Control Plan. Sediment -laden waters will be collected and treated before release to Stream A and existing storm drains. The on-site drainage pattern will not change during or after construction. 2) Could waste material enter ground or surface waters? If so, generally describe. Because groundwater may be encountered during construction, construction - related hazardous materials (including gasoline, diesel, motor oil, transmission fluid, hydraulic oil, radiator coolant, and brake fluid) accidentally spilled near the excavated areas could contaminate groundwater. To prevent such contamination, a Spill Prevention, Control, and Countermeasures (SPCC) plan will be implemented including appropriate prevention and cleanup measures of accidental spills. d.

This will include flagging of clearing limits near Stream A in the undeveloped City - owned parcel and protection of existing catch basin inlets along SW 7th Street and Naches Ave SW. • Stockpiles of fill materials will be covered to prevent erosion during storm events • Concrete wash water will not be allowed to enter the storm drains or stream • Runoff from saw -cutting the pavement will not be allowed to enter the storm drains or stream • Excavated materials not used on-site will be hauled from the site and disposed of in a facility approved by the City • Roadway areas adjacent to the site shall be clean of silt by frequent sweeping or vacuuming • during extended periods of dry conditions, dust shall be limited by street sweeping • Groundwater encountered during stormwater pipe installation activities will be treated before discharge to a storm drain or sewer system if it does not meet state water quality standards • Site erosion control BMPs will be inspected by the City and Contractor regularly to ensure performance. 4. PLANTS Check or circle types of vegetation found on the site: X deciduous tree: alder, maple, aspen, other _Xevergreen tree: fir, cedar, pine, other __X_ shrubs _X_ grass pasture crop or grain wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other water plants: water lily, eel grass, milfoil, other _X_ other types of vegetation b. What kind and amount of vegetation will be removed or altered? Approximately 700 square feet of upland forest vegetation will be cleared on the undeveloped City -owned parcel. This will include the removal of six red alder and willow trees that are between 8 and 12 inches dbh (diameter breast height), shrubs (primarily salmonberry and Himalayan blackberry), and herbaceous plants (primarily sword fern and groundcover species). The purposes of vegetation removal are to (1) facilitate conditions for stormwater pipe and - 11 - 06109 C:%UserslhbernardolAppDatalLocal\MicrosoftlWindows%Temporary Internet FileslContent.OutlooklHU9N7LYEISW 7th_SEPA_Final.doc outfall installation and (2) remove invasive species prior to native plant installation as part of riparian buffer enhancement activities. List threatened or endangered species known to be on or near the site. No threatened or endangered plant species are known to be on or near the site. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: Areas disturbed by project activities will be revegetated following construction. Any areas of lawn disturbed by the project will be re -seeded or re -sodded. Cleared areas on the City -owned parcel will be revegetated with native plants well-suited to on-site environmental conditions. Detailed information on the proposed planting is provided in the Wetland Assessment Report and Buffer Mitigation Plan for the SW 7`h Street/Naches Ave SW Storm System Improvement Project (Herrera 2013). 5.

Describe the utilities that are proposed for the project, the utility providing the service, and the general construction activities on the site or in the immediate vicinity which might be needed. The project will include approximately 3,330 feet of 60 -inch diameter trunk storm drain that would be installed parallel to the existing system from its current outfall at Naches Avenue SW to approximately Lind Ave SW. The pipe will travel along Naches Avenue SW and SW 7th Street and pipe depths will range from approximately S to 11 feet. A separate element of the project includes stormwater treatment retrofitting along SW 7th between Naches Ave SW and Lind Avenue SW. The City applied for and obtained a grant from the Washington State Department of Ecology for water quality retrofits along SW 7th Street. This will include installing 30 to 40 Filterra systems. Most of the trenching for the 60 -inch diameter trunk storm drain will be temporarily shored with trench boxes to minimize impacts to the roadway. Constructing the 60 -inch -diameter trunk will require relocating several utilities. These utilities include both public utilities (owned by the City of Renton) such as water and sewer lines and private utilities such as gas, power, fiber optic, and telephone. C.
