(I) Identify Lake Okeechobee Watershed Construction Project facilities designed to contribute to achieving all applicable total maximum daily loads established pursuant to s.
403.067 within the Lake Okeechobee watershed.
(II) Identify the size and location of all such Lake Okeechobee Watershed Construction Project facilities.
(III) Provide a construction schedule for all such Lake Okeechobee Watershed Construction Project facilities, including the sequencing and specific timeframe for construction of each Lake Okeechobee Watershed Construction Project facility.
(IV) Provide a schedule for the acquisition of lands or sufficient interests necessary to achieve the construction schedule.
(V) Provide a detailed schedule of costs associated with the construction schedule.
(VI) Identify, to the maximum extent practicable, impacts on wetlands and state-listed species expected to be associated with construction of such facilities, including potential alternatives to minimize and mitigate such impacts, as appropriate.
(VII) Provide for additional measures, including voluntary water storage and quality improvements on private land, to increase water storage and reduce excess water levels in Lake Okeechobee and to reduce excess discharges to the estuaries.
(VIII) Develop the appropriate water quantity storage goal to achieve the desired Lake Okeechobee range of lake levels and inflow volumes to the Caloosahatchee and St. Lucie estuaries while meeting the other water-related needs of the region, including water supply and flood protection.
(IX) Provide for additional source controls needed to enhance performance of the Lake Okeechobee Watershed Construction Project facilities. Such additional source controls shall be incorporated into the Lake Okeechobee Basin Management Action Plan pursuant to paragraph (b).
c. Evaluation.-Within 5 years after the adoption of the Lake Okeechobee Basin Management Action Plan pursuant to s.
403.067 and every 5 years thereafter, the department , in cooperation with the other coordinating agencies, shall conduct an evaluation of the Lake Okeechobee Watershed Construction Project and identify any further load reductions necessary to achieve compliance with the Lake Okeechobee total maximum daily loads established pursuant to s.
403.067. The district shall identify modifications to facilities of the Lake Okeechobee Watershed Construction Project as appropriate to meet the total maximum daily loads. Modifications to the Lake Okeechobee Watershed Construction Project resulting from this evaluation shall be incorporated into the Lake Okeechobee Basin Management Action Plan and included in the applicable annual progress report submitted pursuant to subsection (6).
