Oct. 7, 2024 project update
Sewer installation from Arbana Drive to North Revena Boulevard has been completed and the contractor is performing testing and restoration of this section over the next two weeks.
Open cut construction will continue through early November within Maryfield Wildwood Park from North Revena Boulevard to Westwood Avenue.
Trenchless installation of new sewer from Westwood Avenue to Doty Avenue is starting the week of Oct. 7. This installation was originally planned to occur from Westwood Avenue; however, site conditions have resulted in a shift of pipe installation from Doty Avenue.
To accommodate pipe installation from Doty Avenue, Doty is now closed from Dexter Avenue to Linwood Avenue. Westwood Avenue has been reopened between Maryfield Drive and Linwood Avenue. This road configuration will remain until approximately late October, when both Doty and Westwood will be closed for 2 weeks for final connections and restoration.
Updated road closures associated with the project:
- Arbana Drive – Will remain closed through mid-October.
- North Revena Boulevard and Wildwood Avenue – Open throughout construction
- Westwood Avenue – Closed late October through mid-November
- Doty Avenue – Closed through mid-November
- Dexter Avenue – West Bound Detour anticipated Spring 2025
For information on road closures for this and other projects this construction season, please the road/lane closure page.
Project limits
North of Dexter and West Huron Street, between Lyn Anne Court and Arbana Drive. The project will involve Dexter, Doty, Westwood Avenue, Maryfield Wildwood Park, Wildwood Avenue, Revena Boulevard, and Arbana Drive. The map below shows the proposed sewer route.
Why is this project being done?
Ann Arbor's LynAnne-Arbana Sewer Project, funded through the Development Offset Mitigation Program (DOM), involves the replacement of 4,300 feet (0.8 miles) of Existing Sanitary Sewer from the Maple Ridge Apartments to Arbana Drive. The existing sanitary sewer line through the project area was primarily constructed in the 1920s to serve the northwest portion of the city.
This project is being done:
- To address sewer surcharging and maintenance issues
- As a continuation of past sewer projects from West Park to Arbana Drive
- To maintain a key natural corridor
As part of this project, the city will:
- Install the new, larger sanitary sewer and connect it to the existing system.
- Maintain existing sanitary sewer service throughout the design and construction.
- Restore areas following construction, including green space and pavement.
Possible impacts to residents
- Staggered local road closures at Arbana, Westwood/Doty. Access to residences will be maintained.
- Brief lane closures along Dexter.
- Sections of Maryfield Wildwood Park will be closed to public.
- Local road closures, access to residences will be maintained.
- Tree removals.
- Construction noise, including generators for bypass pumping as well as some dust and debris in the areas of work.
Cost and funding source
This project is being funded by the City of Ann Arbor Developer Offset-Mitigation Program, which uses developer payments to fund sanitary sewer wet weather capacity improvement projects.
