Stormwater Management Action Planning

The Phase 2 Municipal Stormwater Permit S5.C.1(d) is requiring the City of Puyallup to go through a ‘Stormwater Management Planning’ process. 

The first steps of this permit requirement is as follows:

• Complete a receiving water assessment which documents and assesses existing information related to the local receiving waters and contributing area conditions to identify which receiving waters are most likely to benefit from stormwater management planning.  This has been completed.   

Step 2:

• Complete a receiving water prioritization informed by the assessment and other local and regional information.  We are to determine which receiving waters will receive the most benefit from stormwater facility retrofits.  We are currently working on this phase.  

The City will be scheduling a public meeting so that the city can present these first 2 steps to the public and solicit input.

Future Steps:

• There will be future phases of work associated with the planning process as outlined in the Ecology Phase 2 permit.  
• Among other steps, we will have to identify retrofits.  The retrofits and actions shall be designed to: 
  • 1) conserve, protect, or restore receiving waters through stormwater and land management strategies that act as water quality management tools, 
  • 2) reduce pollutant loading, and 
  • 3) address hydrologic impacts from existing development as well as planned for and expected future buildout conditions.  

There are not mechanisms to require these retrofits to be installed with the city’s current permit, but we expect the implementation will be required in later permit updates/versions.
