Bay View Wetland/Grand Trunk Wetland Restoration


The Bay View wetland is one of the only remaining wetlands in the Milwaukee Estuary, an area that was historically an expansive freshwater marsh. Restoration of this remnant wetland has been identified as an important habitat restoration project within the Milwaukee Estuary AOC as well as an important step in the revitalization of the harbor area. The Bay View wetland restoration has been identified as a management action for the Loss of Fish and Wildlife Habitat beneficial use impairment in the Milwaukee Estuary AOC Remedial Action Plan Update for 2016. This project will contribute to the completion of one management action. The management action projects were selected in consultation with the Fish and Wildlife Technical Advisory Committee (Tech Team). The Tech Team identified the following necessary project elements, fish and wildlife goals addressed by the project and metrics for evaluating the project.


The City of Milwaukee has proposed restoring this site which includes a large wetland complex that is hydrologically connected to the Kinnickinnic River and Estuary. The goal is to restore the wetland to be a benefit for fish and wildlife as well as an asset for the community. The Redevelopment Authority of the City of Milwaukee (RACM) has been working AECOM to determine a baseline engineering scenario and preliminary cost estimate to manage soil and sediments and develop a remedial action plan. This preliminary work was completed using Fund for Lake Michigan (FFLM) resources. The proposed Scope of Work for this next phase of the project wil include hiring a consulting firm to develop a final ecological restoration plan, obtaining regulatory approvals, developing construction documents and specifications, obtaining permits, hiring owner's rep services, and conducting public outreach.

Study Design

These elements, goals and metrics will be included in the final design and implementation of the Bay View Wetland Restoration project (see appendix C, 2015 Milwaukee Estuary AOC Remedial Action Plan Update). The City is already incorporating these elements into the feasibility planning phase of the project. • A seiche wetland with a passively controlled hydrologic connection to the river and in turn estuary. The connection should be passable by aquatic organisms, with northern pike the target species to use for design purposes. • An adequate buffer between aquatic habitats and development (as defined in goal 3 of the Draft Milwaukee Estuary AOC Fish and Wildlife Plan). • Any passive recreational activities on site should not interfere or be in conflict with the habitat or wildlife value of the site. • Incorporate ephemeral wetlands on the site that remain fish-free and preserve, enhance and/or creating snake denning sites. These are critical habitats for semi-aquatic SLCI are already present on site. • Preserve and restore upland habitat on site that support sustainable SLCIs (i.e. first do no harm to existing species inhabiting the site). • An invasive species and vegetation management plan (aquatic and terrestrial) with provisions made for long-term implementation. • A stormwater management plan for the entire site is recommended. • Some type of permanent conservation protection for the site (conservation easement or equivalent). • Maximize benefits for multiple species (fish, waterfowl, invertebrates, etc.) with a focus on SLCI (see Species Checklists and match SLCI to proposed habitat goals). • If possible, provide access to the wetland for canoes or kayaks, but limiting access to only non-motorized vessels is recommended.
