Asotin, 45th and Cushman Improvements

Asotin, 45th and Cushman Improvements


The Asotin, 45th and Cushman Road and Utility Improvement project is intended to reduce the quantity of stormwater entering Wapato Lake and the Flett Creek Watershed. The City of Tacoma Environmental Services Department received a grant from the Washington State Department of Ecology to replace Asotin Street from South 42nd Street to South 48th Street with green infrastructure.

This new street was constructed with permeable pavement that allows the rainwater falling on the street to soak into the ground. This project was designed to reduce the quantity and improve the quality of water entering Wapato Lake and the Flett Creek Watershed.

Environmental Services and Tacoma Water also replaced storm sewer pipe and extended the water main in various locations.  This required roadway improvements on half of South 45th Street from Asotin Street to Cushman Avenue and on Cushman Avenue from 44th Street to 46th Street.


A public meeting regarding the project was held on Wednesday, February 4, 2014, at Fire Station 8 on South Alaska Street.
