Mountlake Terrace Lake Ballinger Aquatic Ecosystem Restoration Project


The U.S Army Corps of Engineers, Seattle District, has partnered with City of Mountlake Terrace to restore wetlands, riparian corridors, and fish and wildlife habitat within Lake Ballinger under Section 206 of the Continuing Authorities Program (CAP). This program authorizes the Corps of plan, design, and construct small scale projects under existing program authorities from Congress. The project will create and preserve critical habitat for species of concern (e.g. amphibians) and provide significant habitat for migrating birds and many species of waterfowl on the Pacific Flyway. 

The project site is located at Ballinger Park in Mountlake Terrace.


The sponsor of the project is the City of Mountlake Terrace, Washington.
