Project Proposal: The project site is located at King County’s South Treatment Plant (South Plant) in Renton at 1200 Monster Rd SW (Parcel No. 242304-9006). The South Plant is a secondary wastewater treatment facility owned and operated by King County Department of Natural Resources and Parks (DNRP) Wastewater Treatment Division (WTD). The City of Renton issued a Conditional Use Permit, Site Plan, Shoreline Exemption, and Street Modification for the King County South Plant Biogas & Heating Systems Improvement Project on June 12, 2018 (Hearing Examiner’s Final Decision on LUA18-000188). The project proposal includes modifications to the existing wastewater treatment plant processes. The area of work totals approximately 8,000 sq. ft. within the approximately 72-acre site, and would include approximately 200 cubic yards of cut and 45 cubic yards of fill. In addition three (3) non-significant trees (four (4), five (5), and eight (8) inches) are proposed for removal. The proposed work area is within the interior of the existing South Plant site and is located within an existing developed area. The parcels have been mapped, by City of Renton (COR) Maps, with moderate coalmine hazards, regulated shoreline – shoreline high intensity, high seismic hazards, regulated slopes, moderate/high landslide hazards, special flood hazard area (100 year flood) – FEMA Zone AE, and wetlands. The project site has been mapped with high seismic hazards. Springbrook Creek is located offsite to the east. The proposed project would be located outside of the 200-foot shoreline jurisdiction of Springbrook Creek. Current Use: Currently the site is occupied by King County’s South Treatment Plat (South Plat). South Treatment Plant Biogas Near Term Page 2 of 5 October 24, 2024 1. Zoning /Land Use Designation, and Overlays: The property is located within the Employment Area (EA) land use designation and the Heavy Industrial (IH) zoning designation. Sewage disposal and treatment plants also require a Hearing Examiner Conditional Use Permit in the IH zone. According to the submittal summary, the plant was previously permitted under a Conditional Use Permit (CUP) as part of a previous site enlargement project (Metro Treatment Plant at Renton – Enlargement III project). 2.

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- 130H1e can be met. Tree retention standards shall be applied to the developable area, as defined in RMC 4-11- 040, Definitions D, of a property. 8. Parking: The following ratios would be applicable to the site: USE NUMBER OF REQUIRED SPACES Uses not specifically identified in this Section Department of Community and Economic Development staff shall determine which of the below uses is most similar based upon staff experience with various uses and information provided by the applicant. The amount of required parking for uses not listed above shall be the same as for the most similar use listed below. Warehouses and indoor storage buildings: A minimum and maximum of 1 per 1,500 square feet of net floor area. It should be noted that the parking regulations specify standard stall dimensions. Surface parking stalls must be a minimum of 9 feet x 20 feet, compact dimensions of 8½ feet x 16 feet, and parallel stall dimensions of 9 feet x 23 feet; compact surface parking spaces shall not account for more than 30 percent of the spaces in the surface parking lots. ADA accessible stalls must be a minimum of 8 feet in width by 20 feet in length, with an adjacent access aisle of 8 feet in width for van accessible spaces. The appropriate amount of ADA accessible stalls based on the total number of spaces must be provided. Compliance with the parking regulations would not be required, as no new buildings are proposed. 9. Access/Driveways: The primary access to the northern portion of the Treatment Plant, where the project will be developed, is via SW 7th Street. However, there are additional driveways located off Monster Road SW, Longacres Dr SW, and SW Grady Way. No changes in access are proposed. The maximum driveway slopes cannot exceed 15%. If the grade exceeds 15%, a variance is required. Driveways exceeding 8% shall provide slotted drains at the lower end. 10. Critical Areas: The project site has been mapped with moderate coalmine hazards and high seismic hazards. The applicant shall contract with a geotechnical engineer in order to verify that the earthwork, foundation and other recommendations have been properly interpreted South Treatment Plant Biogas Near Term Page 5 of 5 October 24, 2024 and implemented in the design and engineering plan documents. Additionally, the applicant shall complete an analysis on Coal Mine Hazards in the area pursuant to RMC 4-8-120D.7 Geotechnical Report, Coalmine-Medium. Springbrook Creek is located offsite to the east. Springbrook Creek is a Shoreline of the State and is subject to the provisions of the Shoreline Management Act. If any work is proposed within 200 feet of Springbrook Creek, the proposal would be required to comply with the City’s Shoreline Master Program. In addition, a floodplain is mapped on the project site. If any development is proposed within the floodplain, a flood hazard study and Biological Assessment would be required at the time of formal land use application. The study would need to demonstrate that the proposed development would be constructed one (1) foot above base floor elevation for the 1995 Flood Insurance Rate Map (1995 FIRM Map) and provide an analysis as to whether the proposal would require compensatory storage. Finally, the City’s COR mapping system has identified a wetland within 200-feet of the site. This wetland could be associated with Springbrook Creek. If this wetland is associated with Springbrook Creek it would be regulated by the Shoreline Master Program (RMC 4-3-090). All reasonable efforts should be taken to ensure that the proposed activities do not result in net loss of ecological functions. If the wetland is found to be separated from Springbrook Creek, then the wetland would be regulated by the Critical Areas Regulations. As the project is separated from the wetland via an access road, the Critical Area Regulations may not apply to development per RMC 4-3- 050B.1.g, as determined by the Administrator. Beyond the established critical area buffer, all structures would be required to provide a minimum 15-foot building setback. 11. Environmental Review: In accordance with WAC 197-11-800, the repair, remodeling, maintenance, or minor alteration of existing private or public structures, facilities or equipment, including utilities, recreation, and transportation facilities involving no material expansions or changes in use beyond that previously existing would be exempt from Environmental (SEPA) Review. 12. Permit Requirements: The proposal would require a building permit. The fee for any Code Modifications are $290 each. A 5% technology fee would also be assessed at the time of land use application. All fees are subject to change. Detailed information regarding the land use application submittal can be found on the City’s Permit Center website (www.Rentonwa.gov). The City now requires electronic plan submittal for all applications. In addition to the required land use permits, separate construction and building permits may be required. 13. Impact Fees: As the proposal would not include the construction of new buildings Impact Fees would not be required. The city’s 2023-2024 fee schedule is available for your review on the City’s website. 14. Expiration: Once the Building Permit application has been approved, the applicant has one (1) year to complete the permitted work before the approval becomes null and void. A single one-year extension may be granted. It is the applicant’s responsibility to monitor the expiration dates.
