The proposed building would have an approximate height of 19 feet. The project site totals approximately 2.31 acres in area and is located within the Heavy Industrial (IH) zone and Employment Area (EA) Comprehensive Plan Land Use Designation. No changes in access or parking are proposed as a result of the project proposal. The project site is mapped with a flood h azard area, sensitive slopes (slopes with grades between 25 to 40 percent), a seismic hazard area, and a wetland. In addition, Panther Creek (a Type F stream) is mapped off-site to the north of the project site. The project site is also located within the Urban Conservancy Shoreline Designation of Springbrook Creek Reach C. The critical area buffer requirements may not apply to development proposed on sites that are separated from critical areas by pre-existing, intervening, and lawfully created structures, roads, or other substantial existing improvements. All proposed work would be conducted within existing developed portions of the project site. Exist. Bldg. Area SF: 119,112 sq. ft. Proposed New Bldg. Area (footprint): Proposed New Bldg.

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: A seismic hazard area and sensitive slopes (slopes with grades between 25 to 40 percent) are mapped on the project site. A geo-technical engineering report was not required to be submitted with the project application as the proposed development would occur within existing paved, developed portions on the eastern side of the project site. The topography of the project site in the vicinity of the proposed location of the switchgear building is flat. The building would be pre-manufactured, not occupied, and would weigh approximately 47,000 pounds. The building would not have water or sanitary sewer connections. A new roof drain is proposed to discharge to the gravel area along the eastern site boundary or to the existing stormwater system on site. The site currently is (and would continue to be) served with electricity from the on-site Puget Sound Energy (PSE) Substation. Very minor grading of the existing gravel surface would be completed to place an approximately 15-foot by 33-foot concrete slab for placement of the new Switchgear Building. Additionally, some conduit trench excavation (approximately 30 feet in length by 1 foot in width by 3 feet in depth; approximately 3 cubic yards excavated soil) would be completed to install 5 kV power service to the new Switchgear Building from the PSE Substation; 5 kV power service from the new Switchgear Building to the existing pump motors (approximately 150-foot long by 3-foot wide by 3-foot deep; approximately 50 cubic yards), and a low voltage service to the on-site programmable control system. The building would be for use in a 4,160 volt three-phase, three-wire 60 Hertz system. All inside wiring within the switchgear will conform to the latest version of the NEC. The building manufacturer would obtain the Washington State Department of Labor and Industries approval (Gold Seal) and affix the approval label before the building leaves the factory. The entire switchgear equipment is proposed to be UL-Certified, DocuSign Envelope ID: 8971D015-4EAE-42B5-B0FC-67A581E5AF5A City of Renton Department of Community & Economic Development Renton Station Switchgear Building Staff Report to the Environmental Review Committee LUA21-000378, ECF, SA-A, CU-A Report of December 6, 2021 Page 3 of 4 SR_ERC Renton Switchgear_FINAL designed, tested and assembled in accordance with the latest applicable standards. As the proposed switchgear site is located within a seismic hazard area, the new building would be designed per IEEE Standard 693, latest edition, and the current 2018 International Building Code (IBC) with appropriate accelerations. There are no new impervious surfaces proposed as a result of project construction. The project site would include the installation of a 15 ft by 33 ft (495 sq. ft) gravel pad to support the proposed 12 ft by 30 ft (360 sq. ft.) building within 529,649 sq. ft. of existing impervious surfaces. The eastern half of the site, where the proposed Switchgear Building would be located, currently is paved with asphalt concrete or crushed rock. No landscaping or tree removal is proposed as a result of project construction. It is anticipated that any soil impacts resulting from project construction would be adequately mitigated by the City’s adopted erosion control standards; therefore, no further mitigation is recommended. Mitigation Measures: None recommended Nexus: N/A 2. Water a. Wetland and Stream Impacts: The applicant submitted a Critical Areas Assessment Memo, prepared by Geo Engineers, dated September 29, 2021 (Exhibit 5) with the project application materials. Wetland and flood hazard areas are mapped along the western and northern portions of the project site, the 200-foot shoreline jurisdiction of Springbrook Creek (a Type S stream and designated shoreline) is mapped along the western portion of the project site, and Panther Creek (a Type F stream) is mapped along the north portion of the project site. The existing developed portions of the site are located approximately 470 feet east of Springbrook Creek and approximately 130 feet south of Panther Creek. The proposed building would be located approximately 250 feet from the mapped wetlands and flood hazard area, and over 400 feet from Panther Creek on the north side of the developed parcel and over 830 feet from Springbrook Creek on the west side of the developed parcel. The western ends of the electrical excavations required for the proposed switchgear building would be approximately 150 feet from the mapped wetlands along the north side of the project site, and 270 feet from Panther Creek. The existing developed conditions of the project site as well as the proposed development are proposed above the existing wetland, stream, and flood hazard elevations on existing developed surfaces. The facility is paved, fenced, and does not currently provide buffer function. It is not anticipated that the project proposal would have any adverse impacts on existing onsite wetland, stream or floodplain critical areas or associated buffers; therefore, no further mitigation is recommended. Mitigation Measures: None recommended Nexus: N/A D. Comments of Reviewing Departments The proposal has been circulated to City Department and Division Reviewers.
