On November 8, 2011, the Board of County Commissioners approved the Master Agreement with Carollo Engineers, Inc. of Sarasota, FL to provide Utilities Engineer of Record services. This Master Agreement was established for the purpose of conducting studies and preparing reports regarding maintenance and operation of existing facilities, systems and connections; performing rate studies and providing technical assistance on all utility issues, operational, technical, engineering and financial issues, including but not limited to, bond refinancing, grant funding, loans and bond issues related to utility systems.

On July 27, 2015, the County approved Work Assignment 54 to provide preliminary investigation and design services associated with Phase II repairs to the Lake Manatee dam and its appurtenant structures for a total cost of $570,012.00.
