East 40th Street GSI and Utility Improvements


The City of Tacoma's Environmental Services Department, Public Works Department, and Tacoma Public Utilities have partnered to plan and implement an integrated approach to retrofit the East 40th Street roadway from McKinley Avenue to Portland Avenue. The new permeable roadway will be designed with traffic safety improvements for reducing speeds and an enhanced pedestrian and bicycle experience on a new shared use path. The improvements will also include green infrastructure bioswales, new stormwater and water pipes, and new sidewalks and curb ramps. Public and private utilities will also be replaced in coordination within East 40th Street from McKinley Avenue to Portland Avenue.


The 40th Street Green Infrastructure Project provided improved water quality to 30 acres in the First Creek, Lower Puyallup Watershed. This area is home to a number of wildlife species, habitats, and various wetlands. The project helped create a healthy groundwater flow entering First Creek, restored the area to its natural conditions, and reduced neighborhood flooding. Watch the Tacoma Reports video of the project below!
