Adopted Stormwater Manual
The city adopted the 2019 Stormwater Management Manual for Western Washington (SWMMMWW) on June 20th, 2022 and city council has approved the use of this version of the manual.
Stormwater & Washington State Vesting
All development applications submitted on or after July 1, 2022, must comply with the 2019 Stormwater Management Manual for Western Washington (SWMMWW).
Important notice about projects permitted under earlier versions of the SWMMWW.
Per requirements, in Puyallup’s Phase 2 Municipal Stormwater Permit (effective date August 1, 2019) projects, that have vesting rights per Washington state vesting doctrine*, and were applied for under the 2014 SWMMWW prior to July 1, 2022 that have not **started construction by January 1, 2027, and projects permitted under earlier versions of the SWMMWW that have not **started construction by January 1, 2022, must be revised to comply with the requirements of the 2019 SWMMWW, or subsequent versions as directed by state regulations. Revisions will need to be approved by Development and Permitting Services, or its successor agency prior to construction.
**“started construction” means, the site work associated with, and directly related to the approved project is at a stage where rough grading is complete, or utilities are installed. For rough grading to be considered complete, elevations are within 1 foot of final design elevations.
*Applications that do not have vesting ability per Washington State vested right doctrine must have had permit issuance prior to July 1, 2022 (and start construction prior to January 1, 2027) to continue to utilize the 2014 SWMMWW for development. Vested rights only apply to applications such as building permit, short plat or Major subdivision applications and development agreements.
