Burnham Canal Ecosystem Restoration - Bid Document Preparation and Advertisement


The Burnham Canal Ecosystem Restoration project is conducted by Milwaukee Metropolitan Sewerage District (MMSD). MMSD will be implementing a wetland restoration plan designed by the U.S. Army Corps of Engineers (USACE) in October 2017. The proposed plan consists of two phases. The Burnham canal is located in the City of Milwaukee, Milwaukee County, Wisconsin. The Canal was dredged out of wetlands in the 1870s to provide access to the Menomonee River for industries located in the southern portion of the Menomonee River Valley. The Canal was a federally-authorized channel until the mid-1980s. Navigation is not limited to small watercraft due to the low clearances beneath the 11th Street bridge and the Canadian Pacific Railroad bridge at the east of the Canal. The Canal serves as a discharge point for stormwater runoff from surrounding area including point source (pipes) and non-point source runoff. The Canal is surrounded by primarily industrial land use, and each of these land owners abutting the Canal have riparian rights to the Canal.


The goal of the Burnham Canal Ecosystem Restoration Project - Wetland Base East of 11th - Bid Document Preparation is to perform all necessary tasks to prepare and advertise bid documents for construction of the Wetland Base east of S. 11th Street as designed by the USACE design. This includes the following: 1) Install a low-head, steel sheet pile (SSP) wall at the eastern extend of the project, just west of the I-43 bridge. Install a silt curtain in the Canal upstream and downstream of the SSP wall before its installation. 2) Place a high-strength geotextile on the sediment surface between the 11th Street bridge and the SSP wall. 3) Place wetland granular fill materials over the high-strength geotextile, from the 11th Street bridge to the SSP wall, to Elevation -7.0 feet (ft), City of Milwaukee Datum (CMD).

Study Design

The wetland restoration was designed by the U.S. Army Corps of Engineers (USACE) in October 2017. The USACE proposes the construction be completed in two phases. The initial phase is creating the base for the proposed wetland (Wetland Base). This consists of adding granular fill to build up the bottom of the existing canal. No construction activity will take place for an estimated 2-5 years following the construction of the Wetland Base to allow the underlying sediments to compress. When the compression of the sediment has stabilized, the final phase, construction of the wetland, will process which includes the installation of the remaining fill, wetland soils and substrate, wetland vegetation and post construction vegetation establishment period.
