FROM: Jill Ding, 425-430-6598, jding@rentonwa.gov
SUBJECT: South Treatment Plant (STP) Raw Sewage Pump #3 Replacement
1200 Monster Rd SW, Renton, WA 98057
APN 2423049006
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 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 the removal and replacement of raw sewage pump #3 at the STP, including pump, motor, drive,
controls, and vibration and temperature monitoring systems. Sampling of several surfaces and material in
the project areas would be conducted by King County in the first quarter of 2026. The samples would
undergo testing for hazardous materials. If found, an abatement plan would be developed by the project
team and King County as part of the project. 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 Plant (South Plant).

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 (72.34
acres) 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 lot zoned residential. The proposed work would be located over 120 feet from the nearest
property lines 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 and Impervious Surface Coverage – The maximum building height in the IH zone is 50
feet, except for public facilities. Heights may exceed maximum with a Conditional Use Permit. Building
height shall not exceed the maximum allowed by the subject zoning district or the maximum allowed
pursuant to RMC 4-3-020, Airport Related Height and Use Restrictions, whichever is less.
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 sh all 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 requir es a building permit.
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. The existing facility is fenced, no
new fencing is proposed to continue the existing temporary use.
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.

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.
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.
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, and compact dimensions of 8 feet x 16 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 is via SW 7 th St.
However, there are additional driveways located off Monster Road SW, Longacres Dr SW, and SW Grady
Way. No changes in access are proposed.
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. If any new development is proposed, 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.
South Treatment Plant (STP) Raw Sewage Pump #3 Replacement
Page 5 of 5
March 12, 2026
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 compensato ry 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 o r 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.
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=CityofRenton
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.
