Title
Little Hatchet Creek Stabilization Construction (B)
Explanation
This item is a request for the City Commission to approve the Task Assignment Construction Agreement for the Little Hatchet Creek Stabilization project. The City will contract with TSI Disaster Recovery, LLC to perform the work that will include construction of a retaining wall and installation of a grade control structure.
Little Hatchet Creek is subject to stream channel erosion. The project will stabilize the creek bank with an engineered wall system and protect the Airport Helicopter Hanger from failure into the creek bed. Stream bank failure and channel incision has exposed the Hawthorn geologic feature that contains phosphate. Erosion of this material contributes nutrient pollutants to Newnans Lake. The water quality benefit of this project is estimated to be the removal of 4,723 pounds of total phosphorus per year. The project will achieve the City of Gainesville’s required total phosphorus nutrient reduction under the Orange Creek Basin Management Action Plan for Newnans Lake.
Strategic Connection
This item is connected to Goal 2: Sustainable Community in the City’s Strategic Plan and is a regular priority item.
Fiscal Note
Funding for this project in the amount of $1,306,400.00 is available through the FY 22 SMU Capital Improvement Budget, the GG Capital Project fund, and a $505,000.00 contribution from the Florida Department of Transportation. The FDOT contribution is established within the 2017 Interlocal Agreement for Allocation and Implementation of the National Pollutant Discharge Elimination System Program Requirements and for Basin Management Action Plan Projects.
Recommendation
The City Commission: authorize the City Manager to enter into a Task Assignment Agreement with TSI Disaster Recovery, LLC in the amount of $1,181,400.00 for the Little Hatchet Creek Stabilization project, subject to approval by the City Attorney as to form and legality.
