STORM DRAINAGE COMMENTS:
1. Drainage plans and a drainage report complying with the adopted 2022 Renton Surface Water Design Manual is
required. Refer to Figure 1.1.2.A – Flow Chart of the 2022 Renton Surface Water Design Manual (RSWDM) to
determine what type of drainage review is required for this site. Based on the City’s flow control map, this site
falls within City’s Flow Control Duration Standard area (Matching Forested Conditions). The project site is
located in the Soos Creek Drainage Basin.
a. A preliminary TIR prepared by Tebaldi Engineering, LLC., dated April 8th, 2024, was submitted by the
Applicant with the Land Use Application, which was prepared following the 2021 King County Surface
Water Design Manual. The drainage TIR shall be revised to be in compliance with the current 2022
RSWDM.
b. Core Requirement #2, off-site analysis: An off-site and downstream analysis was performed by Casey Lowe
with the Migizi group in 2022, which is included on Section 3.0 of the TIR. The downstream drainage paths
were field inspected for existing drainage problems and the analysis concluded there are no potential
problems found, and it is not anticipated that the additional flow from the subject property will create any
flooding or erosion risks.
c. Core Requirement #3, per the TIR, a vault of approximately 15,500 cubic feet was proposed to meet the
flow control requirement, which was modeled with WWHM2012 to meet the Leve 2 flow control
standards, which shall be revised to meet City's flow control duration standard (matching forested
condition) per Section 1.2.3 of 2022 RSWDM.
2. Conveyance, Core Requirement #4: All new conveyance systems constructed as part of the project must be sized
to RSWDM standards for the total tributary area (onsite and offsite) that the storm systems serve.
a. The preliminary TIR depicts the new conveyance systems have been designed to convey the 100-year
design storm pipe systems, but no calculation is provided. The calculation and analysis of the new
conveyance system shall be provided and will be reviewed during the civil construction permit review
process.
3. Construction Stormwater Pollution Prevention, Core Requirement #5: The preliminary civil plan and drainage
assessment include an ESC and CSWPP plan.
a. A preliminary CSWPP is provided in Section 8.0 of the TIR. A final CSWPP and ESC plan in compliance of
2022 RSWDM instead of 2021 KCSWDM shall be included within the TIR and utility plans submitted as a
portion of the civil construction permit application.
4. Water Quality, RSWDM Core Requirement #8: If the new plus replaced pollution generating impervious (PGIS)
surface exceeds 5,000 SF, the applicant will be required to provide enhanced basic water quality treatment.
a. The preliminary TIR indicates that the total PGIS is less than 5,000 SF and water quality treatment is not
required. Staff has reviewed the preliminary analysis and determined it is acceptable.
5. Appropriate on-site BMPs satisfying Core Requirement #9 will be required to help mitigate the new runoff
created by this development to the maximum extend feasible. On-site BMPs shall be evaluated as described in
Section C.1.3 of the 2022 RSWDM. A preliminary drainage plan, including the application of on-site BMPs, shall
be included with the land use application, as appliable to the project. The final drainage plan and drainage
report must be submitted with the utility construction permit.
a. The preliminary TIR depicts that soil amendment BMP will be used for pervious surfaces. However,
perforated pipe connection is not evaluated and shall be provided for all proposed connection of roof

downspouts per Section 1.2.9.2.2 of RSWDM. The on-site BMPs feasibility analysis will be further reviewed
during the civil construction permit application.
6. A geotechnical report for the site is required and shall be submitted with the land use application. Information
concerning the soils, geology, drainage patterns, vegetation present, water table and soil permeability, with
recommendations of appropriate on-site BMP options with typical designs for the site from the geotechnical
engineer, shall be submitted with the application. The geotechnical report should include an on-site infiltration
test to clearly show if the site is suitable or unsuitable for infiltration.
a. A geotechnical report prepared by Migizi Group, Inc., dated January 24, 2019 (revised March 31, 2020),
was submitted by the Applicant with the Land Use Application.
b. The geotechnical report indicates the site is underlain by relatively impermeable, glacial till soils,
infiltration is not recommended for this site, however, permeable surfacing can be used in the upper soil.
The groundwater seepage was encountered at the top of the impermeable layer of glacial till deposits
approximately 2 feet and 3 feet below existing grades.
7. The 2024 Surface water system development fee (SDC) is $2,300.00 per new single-family lot. This is payable
prior to issuance of the construction permit and are not vested to the rates at land-use approval. This fee is
subject to change based on the calendar year the construction permit is issued.
TRANSPORTATION/STREET COMMENTS:
1. The proposed project fronts 113th Ave SE to the west with existing right of way (ROW) width of approximately
60 feet with an existing paved width of approximately 23 feet. To meet the City’s complete street standards for
a residential access street, per RMC 4-6-060, a minimum ROW width of 53 feet is required. Per RMC 4-6-060 half
of street improvements as taken from the road centerline shall be required and include a 26-foot paved road (13
feet each side), a 0.5-foot curb, an 8-foot planting strip, and a 5-foot sidewalk. No dedication will be required
pending field survey.
a. The submitted preliminary civil plan depicts the street improvements along 113th Ave SE as taken from
the road centerline is a 13 feet paved road, a 0.5-foot curb, an 8-foot planting strip, and a 5-foot sidewalk.
Therefore, the planting strip shall be revised to be 11.5-foot wide, and the sidewalk shall be located
against the west property line of the project site.
2. The proposed project fronts SE 168th Street to the south with existing ROW width of approximately 60 feet with
an existing paved width of approximately 43 feet. To meet the City’s complete street standards for Collector
Arterial Street, the minimum ROW width required on a 2-lane collector street is 83 feet with 30 feet wide travel
width, 8 feet wide paved parking width on both sides, 0.5 feet wide curbs, 8 feet wide landscaped planter, 8 feet
wide sidewalks, and 2 feet clearance at back of sidewalks.
