The Mall Woonerf and Trail Connection Presentation


Project Description

Metropolitan Council Environmental Services (ES), operator of the metro area wastewater collection and treatment system, is replacing and enlarging the aging regional sanitary sewer pipe and structures near Lake of the Isles. Improvements to the regional sanitary sewer system are being completed in coordination with the Minneapolis Park and Recreation Board’s (MPRB) planned improvements for The Mall determined as part of a long-term park planning effort completed in 2020. Work will take place in 2024 to minimize impacts to area residents. Improvements to the regional sanitary sewer system along Humboldt Avenue and the City of Minneapolis’ utility work along have been completed.

The Mall and Woonerf Plaza (tentatively 2024)

The existing sewer pipe along The Mall between Bde Maka Ska Parkway East and Humboldt Avenue will be replaced with new pipes. As part of the long-term park plan for The Mall approved in 2020, the westbound lane of The Mall road west of Irving Avenue will be permanently restored to turf/grass. Other improvements include adding a trail connection to the Greenway and installing the new Woonerf Plaza between Humboldt Avenue and Hennepin Avenue.

MPRB held two community meetings in November 2023 to obtain feedback on the park’s amenities and trail connection options from the community and park visitors. Final design on these features will be completed in spring 2024.
