NOTE: The applicant is cautioned that information contained in this summary is preliminary and non-
binding and may be subject to modification and/or concurrence by official City decision-makers. 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.
I have completed a preliminary review for the above-referenced proposal located at parcel(s)
2423049006. The following comments are based on the Land Use Application submittal made to the City
of Renton by the applicant:
WATER
SEWER
SURFACE WATER
1. A drainage report complying with the current 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 Site Conditions). The site falls within the Lower Cedar River Drainage
Basin. Refer to Figure 1.1.2.A – Flow chart to determine the type of drainage review required in
the RSWM. All stormwater improvements as per the drainage review along with stormwater
improvements in the frontage are required to be provided by the developer.
a. A drainage report dated April 15, 2021, by the City of Renton was submitted with the
Land Use Application.
2. The site is located within Zone 2 of the Aquifer Protection Area (APA), and therefore open facilities
and open conveyance systems may require a liner in accordance with the design criteria in
Sections 6.2.4 and 1.2.3.3 of the 2017 City of Renton Surface Water Design Manual.
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 2017 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. Maintenance access is required for any proposed stormwater tracts and shall be designed and
installed in accordance with the City adopted SWDM.
5. If the new plus replaced pollution generating impervious surface area exceeds 5,000 SF, the
applicant will be required to provide 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.
6. 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 2017 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.
7. A geotechnical soils report for the site is required per the 2017 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.
8. A Construction Stormwater Permit from Department of Ecology is required IF clearing and
grading of the site exceeds one acre. Applicant must obtain permit and provide proof prior to
Civil Permit issuance.
9. Erosion control measures to meet the City requirements shall be provided.
10. The current City of Renton Surface Water Standard Plans that shall be used in all drainage
submittals are available online at the City of Renton website.

surface, but no less than $2,000.00. Fees that are current will be charged at the time of permit
issuance. There is no storm water impact fee for replaced impervious surface area.
TRANSPORTATION
1. If proposed new construction on the site has a valuation of less than $150,000, street frontage
improvements and right of way dedication are not required. If proposed new construction on the
site has a valuation of $150,000 or more, then the installation of street frontage improvements
