The Three Mile Creek Watershed Restoration project involves engineering and construction to stabilize the bank and stream along Twelve Mile Creek and dredging and restoration of Langan Park Lake, both of which drain into Three Mile Creek and Mobile Bay. The project will improve water quality and help to protect the area’s estuarine and marine water resources.
Why is this project needed?
Increased stream velocity due to stormwater systems have contributed to the degradation of the banks, destabilization of the creek, undercutting of sanitary sewer crossings and sedimentation in the creek and Langan Park Lake.
What will this project address?
In order to reduce downstream sedimentation, the banks and streambed of Twelve Mile Creek from East Drive to Langan Park Lake will be stabilized. Instream structures will be constructed to reduce stream velocity/energy, protect existing sanitary sewer crossings, and increase natural habitat. Dredging of Langan Park Lake will increase the capacity of the lake, support flood control and aid in the apple snail abatement.
The Three Mile Creek Watershed Restoration project is separated into three phases:
Phase 1: Twelve Mile Creek Bank Stabilization University Blvd to Museum Drive
Phase 2: Twelve Mile Creek Bank Stabilization East Drive to University Blvd
Phase 3: Langan Lake Dredging.
Phase 1 and Phase 2 are in final design, anticipated construction start in April 2022. Phase 3 is currently in design with an anticipated construction start in August 2022.
Who is involved?
This project is being implemented by the City of Mobile with the support of a variety of contractors. The team includes planners, scientists, engineers, landscape architects and construction experts.
