Watershed-based Stormwater Retrofit Plan & Pre-design - Background

In 2012 the City of Mukilteo was awarded grant funds provided by the Washington State Department of Ecology (Ecology) through the National Estuary Protection (NEP) Watershed Protection and Restoration Grant Program to develop a Stormwater Strategy Plan based on data and methods from the Puget Sound Characterization Project.  The Watershed-Based Stormwater Strategies Plan identified the Picnic Point Ravine, Big Gulch North, and Big Gulch South sub-basins as high priorities for stormwater retrofits as compared to other sub-basins within the study area.  Details of this plan can be found on the City’s project page here.

Additionally, this project has been featured on Ecology’s interactive Watershed Characterization Project website:

The Watershed-Based Stormwater Strategies Plan identified conceptual engineering strategies in these PAUs that focused on distributed infiltration and treatment of stormwater. Retrofitting these areas directly addresses recovery targets established in the Puget Sound Partnership’s Action Agenda by improving water quality, reducing the frequency and magnitude of peak flow events, and protecting summer stream flows.
The Stormwater Retrofit Plan and Pre-Design projects builds off of the Stormwater Strategies Plan by identifying, prioritizing and selecting stormwater retrofit projects within Picnic Point Ravine, Big Gulch North, and Big Gulch South sub-basins.
This project has been funded wholly or in part by the United States Environmental Protection Agency under Puget Sound Ecosystem Restoration and Protection Cooperative Agreement Grant PC-00J20101 with Washington State Department of Ecology.  The contents of this document do not necessarily reflect the views and policies of the Environmental Protection Agency, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.
