The 12th Street East culverts are partial fish barriers and impede fish passage on Wapato Creek. The historic meandering creek was ditched into a straight channel (in the mid-1960s) along 12th Street East and Alexander Avenue and currently has very limited fish habitat and no floodplain or wetlands. The site currently has numerous cottonwood and madrone trees and extensive invasive vegetation.
Lower Wapato Creek Habitat Project
In partnership with the Puyallup Tribe of Indians, the Port of Tacoma is planning the Lower Wapato Creek Habitat Project. This is a mitigation project that consists of two primary fish and wetland habitat restoration elements:
- Replacement of two fish-barrier culverts that convey Wapato Creek under 12th Street East with a single, fish-passable bottomless culvert or bridge; and
- Relocation of Wapato Creek from a ditched system to a longer, meandering stream channel and associated wetlands. This will include a variety of associated estuarine/wetland habitats and a forested upland buffer to provide an increase in the quantity and quality of fish and wildlife habitat, wetlands, and flood capacity.
The Lower Wapato Creek Habitat is located at 1131 E Alexander Ave. in Tacoma (between 12th Street East and State Route 509 near Alexander Avenue).
The project will re-establish stream and wetland habitat on approximately 20 acres of tidally influenced estuary and fish bearing stream. This type of habitat is very limited within Commencement Bay and is a high priority for restoration. This project will improve habitat on lower Wapato Creek, which will augment the Puyallup Tribe of Indian’s fish and wetland habitat site constructed up stream near Freeman Road.
The purpose of this project is to provide advance or concurrent mitigation for future unavoidable wetland impacts on Port-owned properties and for non-endangered species act (non-ESA) fish/habitat impacts to Wapato Creek (downstream of the site).
