I have completed a review for the above-referenced proposal located at parcel(s) 3123059069. The following comments
are based on the land use application submittal made to the City of Renton by the applicant.
SEWER
1. The new refuse and recycling enclosure must have a drain that is routed to the sanitary sewer.
SURFACE WATER
1. There is an existing drainage covenant recorded on this parcel. Applicant must retain or propose equal
mitigation for stormwater, based on the recorded covenant. In addition, Applicant must mitigate new
impervious areas to the maximum extent feasible.
a. Applicant is proposing to replace the existing splashblock location with a tightline connection to the
existing storm system. A new splashblock will be placed at the north property line to maintain the
mitigation required by the previous project, C19005266.
i. Applicant must re-grade the landscape strip along the north property line to ensure that the
roof runoff does not disperse on the neighboring north property.
2. A drainage report complying with the 2022 Renton Surface Water Design Manual (RSWDM) will be required. Based
on the City’s flow control map, the site falls within the City’s Flow Control Duration Standard (Forested Conditions).
The site falls within the Panther Creek Drainage Basin. Refer to Figure 1.1.2.A – Flow chart to determine the type
of drainage review required in the RSWM.
a. A drainage report by CORE Design was submitted by the Applicant, with the land use application.
b. The Applicant is proposing to mitigate the new impervious surface area with a mitigation trade. 700 SF
of the roof runoff will be routed to a new bioretention swale in the center of the property.
3. Storm drainage improvements along all public street frontages are required to conform to the City’s street and
stormwater conveyance standards. Any new storm drain installed on or off-site shall be designed and sized in
accordance with standards found in Chapter 4 of the 2022 RSWDM and shall account for the total upstream
tributary area, assuming developed conditions for onsite tributary areas and existing conditions for any offsite
tributary areas.
4. If the new plus replaced pollution generating impervious surface exceeds 5,000 SF, the applicant will be required
to provide enhanced basic water quality treatment. Any proposed detention and/or water quality vault shall be
designed in accordance with the RSWDM that is current at the time of civil construction permit application.
Separate structural plans will be required to be submitted for review and approval under a separate building
permit for the detention and/or water quality vault.
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 extent 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 applicable to the project. The final drainage plan and drainage report must be
submitted with the utility construction permit application.
6. A geotechnical soils report for the site is required per the 2022 Renton Surface Water Design Manual Section
C.1.3. Information on the water table and soil permeability (measured infiltration rates), with recommendations
of appropriate on-site BMPs per Core Requirement #9 and Appendix C shall be included in the report. The report
should also include information concerning the soils, geology, drainage patterns and vegetation present shall be
presented in order to evaluate the drainage, erosion control and slope stability for site development of the
proposed plat. The applicant must demonstrate the development will not result in soil erosion and sedimentation,
landslide, slippage, or excess surface water runoff.
7. Erosion control measures to meet the City requirements shall be provided.
8. The current Surface Water Standard Plans shall be used in all drainage plan submittals. The current City of Renton
Standard Details is available online on the City of Renton website.
9. The 2023 Surface water system development fee is $0.92 per square foot of new impervious surface, but no less
than $2,300.00. This is payable prior to issuance of the construction permit. This fee is subject to change based on
the calendar year the construction permit is issued.
