Project Description:
The goal of this project is to meet the 2019‐2024 NPDES Municipal Stormwater Permit requirements for the receiving water conditions assessment (S5.C.1.d.i) and prioritization, (S5.C.1.d.ii) per the new stormwater planning section of the updated permit. Compliance with these permit sections requires completion of phased steps as prescribed in the permit documents.
The effort includes a combination of data analysis, forecasting, and public input to develop a prioritization method and process to determine which local receiving waters will receive the most benefit from implementation of stormwater facility retrofits, tailored execution of surface water planning, as well as other land/development management actions.
Project Timeline:
The receiving waters conditions "assessment" is due to Ecology by March 31, 2022. The receiving waters "prioritization" is due to Ecology by June 30, 2022. The City must comply with these timelines in order to remain fully compliant with the NPDES permit. These permit documents will inform and direct the full update to the "Stormwater Comprehensive Plan", however this plan update is expected to have a longer timeline and will be a separate undertaking in 2022-2023.
Public Workshops:
Public Workshops were held on February 8th & 10th, 2022. These workshops were led by Herrera Environmental Consultants and City staff. A recording of the Feb. 8th workshop has been posted online.
