Overview

The Environmental Services Department received a grant from the Washington State Department of Ecology and has partnered with the Public Works Department, and Tacoma Water Division to replace Puget Sound Avenue and South 50th Street. These new streets will be constructed with permeable pavement that will allow the rainwater falling on to the street and soak into the ground. This project is designed to improve water quality from this area entering the Flett Creek Watershed.

The Puget Sound Permeable Pavement Project offers a unique opportunity to convert this arterial street into green infrastructure using pervious pavement. Flow reduction projects such as this are essential in the Flett Watershed to protect the downstream wetland and creeks while reducing flooding in the watershed. Tacoma’s Flett Creek Watershed, in which this site is located, has a history of flooding and downstream capacity issues due to a flow restricted receiving wetland waterbody.

Project Funding

Green infrastructure is the most cost effective solution for this project. The life cycle cost of traditional design methods is estimated at nearly twice the cost. The green stormwater infrastructure project is being funded by a Department of Ecology grant, Surface Water and Waste Water Utilities, the Public Works Streets Initiative, and Tacoma Water.
