Bay Shore Drive Storm Sewer Improvements

Client: Village of Sister Bay

Location: Sister Bay, Wisconsin

The Village of Sister Bay worked with the Department of Transportation to develop plans to reconstruct Bay Shore Drive (STH 42) through downtown Sister Bay. In advance of roadway reconstruction, Sister Bay upgraded utilities including new water mains and relocating and upsizing sanitary sewers. Storm sewers were constructed in coordination with DOT’s design for STH 42. Donohue provided analysis of upstream flows and design of new storm sewers to convey this flow to the DOT project. Donohue also designed the storm sewer and a new outfall to convey stormwater from the outlet of the DOT project to the bay of Green Bay. All storm sewer flow are routed through a vortex treatment device to improve the quality of the water entering Green Bay. The flow is also diverted from its current discharge point in the marina to a new outfall north of the marina.

For inclusion with the DOT roadway design, Donohue designed or coordinated with DOT designers to accommodate decorative lighting, sidewalk, bicycle paths, overhead utility relocations, and the realignment of the County Walk Drive and Highway 57 intersections.

Donohue worked with the Village to define their needs for these items, coordinate them with surrounding facilities, and worked with the DOT to incorporate the Village’s needs. Donohue worked with the Village to review alternatives for relocating utilities from an easement behind businesses and residences to the STH 42 right-of-way. All sanitary sewer laterals and water services were reconnected to the new sanitary sewer and water mains, respectively. Extensive coordination with the Wisconsin Department of Natural Resources and U.S. Army Corps of Engineers was required to obtain a permit for a new storm sewer outfall into Green Bay, including TSS reduction and treatment for stormwater runoff from the roadway. Donohue prepared bidding documents for the sanitary sewer, water main, storm sewers, utility relocations, and lighting. The Village utilities were constructed in advance of the DOT paving project.

To minimize the disruption to area businesses, the Village conducted a public outreach campaign that started during utility construction and continued until the end of the paving project. The campaign combined the project development and construction timeline for the public utility upgrades designed by Donohue, private utility work coordinated by Donohue, reconstruction of Hwy 42 designed by DOT, reconstruction of a separate project on Hwy 57 designed by a DOT consultant, and marina improvements by another consultant. The campaign focused on working with the Village and area businesses to provide construction information to residents and tourists, including information on detour routes, parking locations, and accessibility of downtown businesses.
