H:\CED\Planning\Current Planning\Admin Docs\templates\Staff Report Templates DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: February 29, 2024 TO: Pre-Application File No. 24-000037 FROM: Andrew Van Gordon, Associate Planner SUBJECT: Kennydale Lakeline Sanitary Sewer West of Lake Washington Blvd N from 2725 Mountain View Ave N to 3903 Lake Washington Blvd N General: We have completed a preliminary review of the pre-application for the above- referenced development proposal. The following comments on development and permitting issues are based on the pre-application submittals made to the City of Renton by the applicant and the codes in effect on the date of review. The applicant is cautioned that information contained in this summary may be subject to modification and/or concurrence by official decision- makers (e.g., Hearing Examiner, Community & Economic Development Administrator, Public Works Administrator, Planning Director, Development Services Director, Development Engineering Director, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. The Development Regulations are available online at https://www.codepublishing.com/WA/Renton. Project Proposal: The applicant proposes to install prefabricated individual lift stations that will intercept the current side sewer exiting homes on the lake side of property on the shoreline of Lake Washington. Sewage will be pumped through a 1.25-inch (1.25”) pressurized force main up to Mountain View Ave N where it will be combined with a shared three-inch (3”) force main up to the King County Interceptor located in Lake Washington Blvd N. A separate electrical system to power the lift stations will be installed parallel to the new force main with some deviation when needed. A control panel and backup generator for the electrical system is intended to be installed between the parking for Kennydale Beach Park and Lake Washington Blvd N. Site restoration will include minor drainage improvements, pavement and landscape restoration. The scope of work will extend approximately from 2725 Mountain View Ave N to 3903 Lake Washington Blvd N. Work will occur within public right-of-way, APN 3124059004, APN 3224059005 and on privately owned property. Access to the private property is proposed through obtaining easements from the individual property owners. Current Use: The existing sewer main is underwater withing Lake Washington. The sewer main was originally constructed in 1972 to intercept side sewers from shoreline homes that previously drained directly into Lake Washington. 1. Zoning /Land Use Designation, and Overlays: The project area is partially located within both the Residential – 6 (R-6) zone and Residential – 8 (R-8) zone. The Urban Conservancy and Single Family Residential shoreline designation in the Lake Washington Reaches overlays the Kennydale Lakeline Sanitary Sewer Page 2 of 6 February 29, 2024 project area. The purpose of the Urban Conservancy environment is to protect, conserve, restore and manage existing areas with ecological functions of open space, floodplain, and other sensitive lands where they exist in urban and developed settings, while allowing compatible uses. The objective of the Single Family Residential Shoreline Overlay District is to accommodate residential development and appurtenant structures that are consistent with the Shoreline Management Element of the Comprehensive Plan. The proposal would be considered a Utilities, Small use. Utilities, Small are defined as: “Small scale facilities serving local areas within the City, including underground power lines, water, sewer, and storm water facilities included within a Council-adopted utility system plan, fiber optic cable, pump stations and hydrants, switching boxes, and other structures normally found in a street right-of-way to serve abutting properties. Facilities also include electric vehicle infrastructure located on public or private property such as a charging station.” Within the R-6 and R-8 zones small utilities use is permitted provided that aboveground public utility facilities, such as water towers, reservoirs, water treatment facilities and pump stations shall be treated with public art, subject to approval by the Arts Commissions. If the proposed facilities are not included in a Council-adopted utility system plan, then the proposal would be considered a Utilities, Medium use. Utilities, Medium are defined as: “Moderate scale facilities serving the City, including subregional switching stations (one hundred fifteen (115) kv and smaller), and municipal sewer, water, and storm water facilities not included in a Council-adopted utility system plan.” Within the R-6 and R-8 zones medium utilities use is reviewed and approved through an Administrative Conditional Use Permit provided that aboveground public utility facilities, such as water towers, reservoirs, water treatment facilities and pump stations shall be treated with public art, subject to approval by the Arts Commissions. 2. Development Standards: The project would be subject to RMC 4-2-110A, Development Standards for Residential Zoning Designations effective at the time of complete application (noted as “R-6 standards” and “R-8 standards” herein). Building Standards – The R-6 standards allow a maximum building coverage of 40 percent (40%) of the lot area; the maximum impervious coverage is 55 percent (55%). The R-8 standards allow a maximum building coverage of 50 percent (50%); the maximum impervious coverage is 65 percent (65%). The maximum wall plat height for both zones is restricted to 24 feet (24’) with a maximum of two (2) stories. Roofs with a pitch equal to or greater than 4:12 may project an additional six (6) vertical feet from the maximum wall plate height; common rooftop features, such as chimneys, may project an additional four vertical feet (4’) from the roof surface. Non-exempt vertical projections (e.g., decks, railings, etc.) shall not extend above the maximum wall plate height unless the projection is stepped back one-and-a-half horizontal feet (1.5’) from each façade for each one vertical foot (1’) above the maximum wall plate height. The maximum wall plate height for detached accessory structures is 12 feet (12’) and the total floor area must be less than that of the primary structure. Accessory structures are also included in building lot coverage calculations. Kennydale Lakeline Sanitary Sewer Page 3 of 6 February 29, 2024 New development would need to comply with the maximum building coverage, impervious surface requirements, and building height regulations of the zone at the time of land use application. Setbacks – Setbacks are the minimum required distance between the building footprint and the property line. The required setbacks for the R-6 zone are: Front yard and secondary front yard (applies to corner lots): 25 feet (25’); Side yard: combined 15 feet (15’) with not less than five feet (5’) on either side; Rear yard; 25 feet (25’). The required setbacks for the R-8 zone are: Front yard: 20 feet (20’) except when all vehicle access is taken from an alley, then 15 feet (15’); Secondary front yard (applies to corner lots): 15 feet (15’); Side yard: five feet (5’); Rear yard: 25 feet (25’). New development would need to comply with zoning setbacks. Compliance with required setbacks for new development would be verified at the time of land use application. 3. Significant Tree Retention: A review of COR Maps appears to show that there are mature trees on the site. When significant trees (greater than 6-inch caliper or 8-caliper inches for alders and cottonwoods) are proposed to be removed, a tree inventory and a tree retention plan along with an arborist report, tree retention plan and tree retention worksheet shall be provided with the formal land use application as defined in RMC 4-8-120. The tree retention plan must show preservation of at least 30% of significant trees. Please refer to RMC 4-4-130, Tree Retention and Land Clearing Regulations for further general and specific tree retention and land clearing requirements. In addition to retaining a minimum of 30% of existing significant trees, the project would be required to provide a minimum tree density of 30 tree credits per net acre. Tree credits encourage retention of existing significant trees with larger trees being worth more tree credits. TREE SIZE TREE CREDITS New small species tree 0.25 New medium species tree 1 New large species tree 2 Preserved tree 6 – 9 caliper inches 4 Preserved tree 10 – 12 caliper inches 5 Preserved tree 12 – 15 caliper inches 6 Preserved tree 16 – 18 caliper inches 7 Preserved tree 19 – 21 caliper inches 8 Preserved tree 22 – 24 caliper inches 9 Preserved tree 25 – 28 caliper inches 10 Kennydale Lakeline Sanitary Sewer Page 4 of 6 February 29, 2024 TREE SIZE TREE CREDITS Preserved tree 29 – 32 caliper inches 11 Preserved tree 33 – 36 caliper inches 12 Preserved tree 37 caliper inches and greater 13 Significant trees shall be retained in the following priority order: Priority One: Landmark trees; significant trees that form a continuous canopy; significant trees on slopes greater than twenty percent (20%); significant trees adjacent to critical areas and their associated buffers; significant trees over sixty feet (60') in height or greater than eighteen inches (18") caliper; and trees that shelter interior trees or trees on abutting properties from strong winds, which could otherwise allow such sheltered trees to be blown down if removed. Priority Two: Healthy tree groupings whose associated undergrowth can be preserved; other significant native evergreen or deciduous trees; and other significant non-native trees. Priority Three: Alders and cottonwoods shall be retained when all other trees have been evaluated for retention and are not able to be retained, unless the alders and/ or cottonwoods are used as part of an approved enhancement project within a critical area or its buffer. The Administrator may require independent review of any land use application that involves tree removal and land clearing at the City's discretion. The Administrator may authorize the planting of replacement trees on the site if it can be demonstrated to the Administrator's satisfaction that replacement requirements in RMC 4-4- 130H.1.e can be met. Unless exempted by critical areas, RMC 4-3-050C, or Shoreline Master Program Regulations, RMC 4-3-090, no tree removal, or land clearing, or ground cover management is permitted on portions of property with buffers associated with shorelines of the State, pursuant to RMC 4-3-090, Shoreline Master Program Regulations. It is expected that removed significant trees will be replaced based on the tree credit value of each significant tree removed. Compliance with required setbacks for new development would be verified at the time of land use application. 4. Fences/Retaining Walls: Fences or retaining walls installed as part of this project must be designated on a landscape plan and grading plan with top of wall and bottom of wall elevations. A fence and/or wall detail should also be included on the plan. A retaining wall that is 4 feet or taller, as measured by the vertical distance from the bottom of the footing to the finish grade at the top of the wall requires a building permit. The maximum height of any fence or retaining wall is 72-inches subject to further height limitations in setbacks and clear vision areas noted in RMC 4-4-040D. A fence shall not be constructed on top of a retaining wall unless the total combined height of the retaining wall and the fence does not exceed the allowed height of a standalone fence. For more information about fences and retaining walls refer to RMC 4-4-040. Kennydale Lakeline Sanitary Sewer Page 5 of 6 February 29, 2024 5. Critical Areas: Per COR Maps the project area will take place within regulated shoreline areas, high erosion hazard areas, medium and high landslide hazard areas, sensitive slope areas and wellhead protection area zone 2. The overall purpose of the wellhead protection regulations is to protect aquifers used as potable water supply sources by the City from contamination by hazardous materials. Some uses are restricted that store, handle, treat, use, or produce substances that pose a hazard to groundwater quality. Development within high seismic hazard areas require a geotechnical study completed by a licensed professional. A geotechnical report and hydrogeologic study may be required based on the final proposed scope of work. Due to the project being located within regulated shoreline areas, shoreline permitting is required. A standard stream or lake study prepared by a qualified biologist would be required to demonstrate compliance with the Shoreline Master Program and development criteria found in Critical Areas Regulations RMC 4-3-090. The study shall demonstrate if the proposal meets the criteria of no net loss of ecological functions as described in RMC 4-3-090D2. If the proposal requires mitigation for substantial impacts to the existing vegetation buffer in order to demonstrate no net loss of ecological functions, a supplemental stream or lake study is required. It is the applicant’s responsibility to determine whether any other critical areas are present on the site prior to formal land use application. 6. Environmental Review: The proposal would require environmental review pursuant to the State Environmental Policy Act (SEPA). The project is located within the Urban Conservancy shoreline designation and therefore WAC 197-11-800 does not apply. An Environmental Checklist must be submitted with the proposal and the City’s Environmental Review Committee is required to issue a Threshold Determination prior to any issuance for permits on the site. 7. Permit Requirements: The proposed project would require a Shoreline Substantial Development Permit, and Environmental (SEPA) Review. The applications would be reviewed concurrently within an approximate timeframe of 6-8 weeks. The 2024 application fees would total $5,071.50 ($3,030 Shoreline Substantial Development Permit review + $1,800 SEPA Review + $241.50 5% technology fee = $5,071.50). Any modification requests to code standards are $290.00 per modification + an additional 5% technology fee. All fees are subject to change prior to submittal. Detailed information regarding the land use application submittal can be found on the City’s Permit Center website. The City requires electronic plan submittal for all applications. 8. Public Information Sign: Public Information Signs are required for all Type II and Type III Land Use Permits as classified by RMC 4-8-080. Public Information Signs are intended to inform the public of potential land development, specific permits/actions being considered by the City, and to facilitate timely and effective public participation in the review process. The applicant must follow the specifications provided in the public information sign handout. The applicant is solely responsible for the construction, installation, maintenance, removal, and any costs associated with the sign. 9. Impact Fees: It is not anticipated that there would be impact fees associated with the project. A handout listing all of the City’s Development related fees is available for your review at https://edocs.rentonwa.gov/Documents/Browse.aspx?id=8217302&dbid=0&repo=CityofRe nton Kennydale Lakeline Sanitary Sewer Page 6 of 6 February 29, 2024 Next Steps: When the formal application materials are complete, the applicant shall have the materials pre-screened prior to submitting the complete application package.
