NOTICE OF APPLICATION
A Master Application has been filed and accepted with the Department of Community & Economic Development
(CED) – Planning Division of the City of Renton. The following briefly describes the application and the necessary
Public Approvals.
DATE OF NOTICE OF APPLICATION: March 20, 2018
PROJECT NAME: King County South Plant Biogas and Heating Systems Improvements Project
PROJECT NUMBER: LUA18-000188, SA-A, CU-H, SME, MOD
PROJECT DESCRIPTION: King County is requesting Administrative Site Plan Review, Hearing Examiner
Conditional Use Permit, Shoreline Exemption, and a Street Modification to replace South Plant's Biogas Upgrading System
(BUS) and heating system to improve the beneficial use of digester gas at King County Wastewater Treatment Division's
South Treatment Plant (STP) while also reliably supplying heat to meet process and space heating demands. The proposed
project is located at 1200 Monster Rd SW (King County Parcel Nos. 2423049006, 2423049097 and 2423049111). The
project site is approximately 4 acres of the 50-acre STP site. The South Plant Biogas and Heating Systems Project would
include the construction of a Heat and Energy Recovery Building (HERB), a new thermal oxidizer, heating system
improvements within the Digester Equipment Building, and utility connections.
The parcel contains one Category IV wetland (Wetland A) and is located approximately 1,000 feet from the Black River
and 250 to 450 feet from Springbrook Creek. No work would be completed within either the wetland or the wetland
buffer. A flood hazard area associated with Springbrook Creek is mapped on a portion of the project site. A portion of the
4,375 square foot (175-foot by 25-foot) temporary stabilized construction entrance would be located within this area, but
no permanent facilities or fill would be located within the mapped flood hazard area. The temporary stabilized
construction entrance would provide construction machinery access to the proposed spoils placement area onsite.
Construction and use of the temporary construction entrance would occur within a portion of the shoreline jurisdiction
of Springbrook Creek. The temporary construction entrance would require approximately 290 cubic yards of cut soil and
approximately 120 cubic yards of quarry spalls. Following grading activities on the spoils placement site, the temporary
stabilized construction entrance would be removed, grades would be restored to their preconstruction condition, and the
area would be permanently stabilized with mulch followed by seeding. Runoff from the building roof and most of the
impervious areas would be collected and routed to a detention vault before being discharged to the existing stormwater
system onsite.
Site improvements include a new driveway around the west and south sides of the HERB, seven uncovered parking stalls
north of the HERB, and concrete walkways and equipment staging areas surrounding the HERB on three sides. Runoff
from a portion of the asphalt walkway would disperse via sheet flow into new and existing landscaped areas where it
would infiltrate. No changes to vehicular or pedestrian access to the site would occur as a result of the proposed project.
Primary access to the northern portion of the Plant is via SW 7th St. There are additional driveways located off of Monster
Rd SW, Longacres Dr SW and SW Grady Way. No frontage improvements or work within the public rights -of-way are
proposed. Roughly 17,000 cubic yards of soil would be excavated and placed on a 1-acre area on open lawn within the
center of the STP site. Spoils would be compacted and seeded to match existing grades and vegetation type. Of the 180
assessed trees, 42 significant trees are proposed to be removed. The applicant has submitted an Arborist Report, Wetland
Assessment Report, Geotechnical Report, Technical Information Report, Trip Generation Memo, and Standard Stream
Study with the application.
