Stormwater Management Action Planning

Project Description:

The goal of Stormwater Management Action Planning is to meet the 2019‐2024 NPDES Western Washington Phase II Municipal Stormwater Permit requirements for the receiving water conditions assessment (S5.C.1.d.i), prioritization, and complete a stormwater management action plan (S5.C.1.d.ii).

This effort includes a combination of watershed data analysis for waterways health, water use importance, and stormwater influences.

Project Goals:

Inventory Lynnwood’s watersheds and waterways
Develop a prioritization method and process to determine which waterways will receive the most benefit from implementation of actions related to stormwater
Develop a plan identifying facility retrofits, land/development management actions, and program enhancements for the highest priority waterway.
