Description
Funding under Project H009 is provided for the replacement of the Lake Hancock P-11 Water Control Structure. This
project is directly related to Project H008, Lake Hancock Lake Level Modification. Project H009 is contingent on the
successful completion of Project H008 in 3 steps: Step (1) provide the preliminary evaluations and incremental
probable costs for raising the normal high operating levels of Lake Hancock to 99.5, 100.0, and the target 100.5 feet
from the current level of 98.7 feet. Step (1) is complete with a recommended target level up to 100.0 feet. The results
of Step 1 were presented to the boards with a staff recommendation for moving forward with Step (2) of the project in
October 2004. Step (2) involves the generation of the detailed information necessary to submit a complete Conceptual
Environmental Resource Permit (ERP) Application, and to specifically identify impacts to private lands for acquisition
and other mitigation needs (environmental, facilities, etc). Major components of the Conceptual ERP include: pre and
post condition analysis; private property, dwelling, environmental, and infrastructure mitigation; outfall structure
operation characteristics; and an anticipated fluctuation schedule for the Lake. Step (3) is the implementation of the
mitigation components as specified in the Conceptual ERP. Costs for design, ERPs, and construction for
environmental and infrastructure mitigation requirements have not been determined. Once these steps have been
completed, construction documents will be completed for the replacement of Structure P-11 and the District will post a
request for bids. Funding for this project is shared by the Governing Board (50 percent), Peace River Basin Board (25
percent), Alafia River Basin Board (12.5 percent) and Manasota Basin Board (12.5 percent). Basin Board funding
percentages are based on Alafia, Manasota, and Peace Basin impacts to the loss of flows in the Upper Peace River
Watershed from ground-water withdrawals.
Benefits
Raising the normal operating water level of Lake Hancock to 100.0 feet NGVD will provide the storage to meet
approximately 50% of the Minimum Flows and Levels Requirements of the upper Peace River. It was also determined
that raising of the operating level along with other District projects will help restore wetland function for several hundred
acres of contiguous lands to Lake Hancock. Project H009 will involve the actual replacement of the present control
structure to achieve these goals.
Costs
The probable cost are projected to be a total of $5,000,000 for this structural replacement project. This cost does not
include any land acquisition costs. Funds encumbered under Project H009 were approved in FY2003 in the amount of
$2,500,000 and an additional $2,500,000 was approved in the FY2009 for implementing the structure replacement
project. The FY2009 funds are from the West Central Florida Water Restoration Action Plan FY2009 State funds. The
FY2003 and FY2009 funds do not include any land acquisition cost.
