East 40th Street GSI and Utility Improvements

The City's Environmental Services, Public Works, and Tacoma Public Utilities have partnered to plan and implement an integrated approach to retrofit East 40th Street from McKinley Avenue to Portland Avenue.

Gravel Detention Facility & Public Trail

This site currently controls stormwater and protects Flett Creek. This summer the City of Tacoma will be removing additional gravel to provide even more protection through increasing the facilities capacity to hold stormwater, which in turn reduces downstream flooding. At the same time a new public trail will be constructed allowing you to enjoy this green space.

Oakland Neighborhood Permeable Pavement Project

The Environmental Services Department received a grant from the Washington State Department of Ecology and has partnered with the Public Works Department to replace Monroe Street, Gunnison Street, and Madison Street with new streets in Tacoma’s Oakland neighborhood. 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.

Today, some 175 years later, Point Defiance is serving as a defender not of land, but of Puget Sound, thanks to the new regional stormwater treatment facility.
