RE: Cedar Ridge Short Plat (C17004067) – Vault Design Criteria/Setback
Stormwater Adjustment 2020-03
Dear Mr. Singh:
The City of Renton has completed review of the storm drainage adjustment request for Cedar Ridge
Short Plat (C17004067) in accordance with the City adopted 2017 City of Renton Surface Water Design
Manual (RSWDM). As the Applicant, you are requesting an adjustment from the 2017 RSWDM Chapter
5, Section 5.1.3.1, Design Criteria/Setback (5-foot setback between vault and tract/easement). More
specifically, you are requesting an adjustment to:
Shift the proposed stormwater vault five (5) feet to the east so that the east wall of the vault is
located on the lot line between Lot 1 and the storm drainage tract, and
Create a 5-foot private storm drainage easement on Lot 1 specifically for vault access and
maintenance.
FINDING OF FACTS (FOF):
1. The proposed stormwater vault will be privately maintained by the home owners within the
Cedar Ridge Short Plat.
2. Access for maintenance of the stormwater vault will be provided utilizing the proposed private
storm drainage easement located on Lot 1.
3. In accordance with RSWDM Chapter 4, Section 4.1.2, a five (5) foot building setback will be
required between the private storm drainage easement and the building on Lot 1, which
maintains the same setback as what is provided currently without the proposed vault shift.
4. Conformance with RSWDM, Chapter 1, Section 1.4.2, Criteria for Granting Adjustments.
Compliance Conformance with Criteria for Granting Adjustments
(see FOFs
1-3)
The Storm Drainage Adjustment shall:
1. Produce a compensating or comparable result that is in the public
interest, AND
2. Meet the objectives of safety, function, appearance, environmental
protection, and maintainability based on sound engineering judgement.

This private easement shall be graded flat to increase maintainability of the stormwater
vault.
