Project Proposal: The project site is located at King County’s South Treatment Pla nt (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 the recoating of the failing division channel lining at the South Plant. 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).

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. Development Standards: The project would be subject to RMC 4-2-130A,
“Development Standards for Industrial Zoning Designations” effective at the time of
complete application (noted as “IH standards” herein).
Minimum Lot Size, Width and Depth – The minimum lot size in the IH zone is 35,000
square feet. There are no minimum lot width or depth requirements. The existing lot
totals 3,151,155 square feet in area and would exceed the minimum lot size
requirements of the IH zone.
Setbacks – Setbacks are the distance between the building and the property line or any
private access easement. The required setbacks in the IH zone are as follows: 15 feet for
a front yard or secondary front yard (20 feet from a principal arterial street); zero for the
rear yard or side yards, except 50 feet if the lot abuts a l ot zoned residential. The
proposed work would occur within the existing division channel replacement
trailers appear to be located over 500 feet from the nearest property line, and would
be outside of any required setback areas. The setbacks for any proposed structures
would be verified at the time of formal application.
Building Height – The maximum building height permitted in the IH zone is 50 feet.
Heights may exceed the maximum with a Conditional Use Permit. Not applicable as no
new structures are permitted.
Building Coverage – There are no minimum lot coverage or impervious surface coverage
requirements within the IH zone.
3. Screening: Screening must be provided for all surface-mounted and roof top utility and
mechanical equipment. The site plan application will need to include elevations and
details for the proposed methods of screening (see RMC 4-4-095).
4. Refuse and Recycling Areas: Refuse and recycling areas need to meet the requirements
of RMC 4-4-090, “Refuse and Recyclables Standards.” For manufacturing and other non-
residential developments a minimum of 3 square feet per every 1,000 square feet of
building gross floor area shall be provided for recyclable deposit areas and a minimum
of 6 square feet per 1,000 square feet of building gross floor area shall be provided for
refuse deposit areas.
5. Fences/Walls: If the applicant intends to install any fences or retaining walls as part of
this project, the location must be designated on the landscape plan or grading plan. A
fence and/or wall detail should also be included on the plan. A fence taller than 6 feet
shall require a building permit or an explicit exemption from the Building Official. 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. A fence
shall not be constructed on top of a retaining wall unless the total combined height of the
South Wastewater Treatment Plant (STP) Division Channel Recoating Project
Page 3 of 6
November 20, 2005
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.
6. Landscaping: Except for critical areas, all portions of the development area not covered
by structures, required parking, access, circulation or service areas, must be landscaped
with native, drought-resistant vegetative cover. The minimum on-site landscape width
required along street frontages is 10 feet and shall contain trees, shrubs, and
landscaping. Street trees in the ROW planter will also be required. Please refer to
landscape regulations (RMC 4-4-070) for additional general and specific landscape
requirements. The proposal would be exempt from compliance with the landscaping
requirements as no new buildings are proposed.
7. Significant Tree Retention: 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, properties subject
to an active land development permit shall comply with minimum tree credit retention
requirements of a minimum of 30 credits per net acre. Tree credits encourage re tention
of existing significant trees with larger trees being worth more tree credits.

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
4-4-130H1e 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 8 feet x 20 feet, compact dimensions of 8½
South Wastewater Treatment Plant (STP) Division Channel Recoating Project
Page 5 of 6
November 20, 2005
feet x 16 feet, and parallel stall dimensions of 8 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 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 developme nt
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
South Wastewater Treatment Plant (STP) Division Channel Recoating Project
Page 6 of 6
November 20, 2005
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 $299 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 2025-2026 fee schedule is available for your review on the City’s website.
14. Expiration: Every permit issued shall expire eighteen (18) months from the date of
issuance. For permits that have expired, a new permit must be obtained and new fees
paid. It is the applicant’s responsibility to monitor the expiration dates.
