water made available by the CERP Loxahatchee
River Watershed Restoration Project.
WATER SUPPLY AND QUALITY
• Completed the Draft 2022 LWC Water Supply
Plan Update with demand projections through
2045 and initiated public review and comment
period. Conducted stakeholder meetings and
coordinated with the Southwest Florida Water
Management District.
• Implemented the DEP Alternative Water
Supplies grant program FY2022, which
provided funding for three alternative water
supplies and nine water conservation projects
with regional stakeholders.
• Significantly advanced the number of local governments that have now
adopted irrigation ordinances that comply with SFWMD’s Year-round
Irrigation Rule.
• Conducted an initial siting analysis for the Picayune Watershed Water
Quality project. The objective of the study is to determine if there is land
available and suitable for implementation of a water quality project in
the Picayune watershed and improve water quality in the Outstanding
Florida Waters.
COMPREHENSIVE EVERGLADES RESTORATION PLAN
• For the Central Everglades Planning Project (CEPP), construction continues
on the EAA Reservoir Project STA and design continues for the CEPP EAA
Canal Conveyance Improvements. Completed design and permitting of
the CEPP North S-620 Structure. The CEPP New Water Draft Validation
Report and design of the seepage management feature were completed.
• Completed the 2nd annual Aquifer Storage and Recovery (ASR) Well
Science Plan to identify potential studies to be conducted to address
scientific uncertainties of phased implementation of ASR wells.
Initiated several ASR wells for testing.
• Completed design and permitting of the remaining component of the
Biscayne Bay Coastal Wetlands Phase I, the Cutler Flow Way and initiated
construction of the S-701 Pump Station.
LAND RESOURCES
• Swept over 150,000 acres of conservation and project lands to control
invasive plant species, resulting in treatment of more than 40,000 acres
of vegetation to maintain the ecological function and values of native
plant species.
• Prescribed burns were conducted on 14,291 acres of fire dependent
plant communities and wetlands on District-managed conservation
and project lands.
RESTORATION STRATEGIES SCIENCE PLAN
Over the 10 years that the Restoration Strategies Science Plan
has been in effect, nine studies have been completed and 12 are
ongoing. In WY2022, the Floating Tussocks study was completed.
The study evaluated factors that contribute to formation of
floating mats of vegetation (tussocks) in STAs and their effects on
phosphorus retention. An unmanned aerial vehicle (i.e., drone)
equipped with imaging sensors took high resolution images of
STA cells planted with emergent aquatic vegetation (EAV). EAVs
are wetland plants that extend above the water surface.
A buoyancy model was developed to inform operational
recommendations to reduce the formation of tussocks in the
STAs. Regular use of drones to survey these areas could provide
early detection, allowing management activities such as planting
of deeply rooted EAV, harvesting, treatments, or lowering water
levels to prevent further tussock expansion. See Chapter 5C for
details about completed and ongoing studies.

RESTORATION STRATEGIES
The design and construction of Restoration Strategies projects is
ongoing with completion of all projects expected by December
2024. In Water Year 2022 (WY2022; May 1, 2021–April 30, 2022),
five milestones were completed on four projects: (1) STA 1 East
(STA 1E) Repairs and Modification, (2) STA 1 West (STA 1W)
Expansion No. 2, (3) G-341 Related Improvements, and
(4) C-139 FEB.
STA 1E Repairs and Modifications were completed in March 2022.
The project leveled out land surface issues of Cells 5 and 7 which
improves treatment performance and is undergoing vegetation
management activities prior to operating.
For the G-341 Conveyance Improvements Project, land needed
was fully acquired in June 2021 and the final design was
completed in March 2022. The C-139 FEB and STA 1 Expansion
No. 2 construction status reports were submitted in
February 2022.

2023 SOUTH FLORIDA ENVIRONMENTAL REPORT – Highlights 11
SEA LEVEL RISE AND FLOOD RESILIENCY
The SFWMD is strongly committed to addressing the impacts of climate
change, including rising sea levels, changing rainfall, and flood patterns.
The SFWMD’s current resiliency efforts focus on assessing how sea level
rise and extreme events, including flood and drought events, happen
under current and future climate conditions, and how they affect water
resources management.
The SFWMD is also making significant infrastructure adaptation
investments that are needed to successfully implement its mission.
As part of its resilience initiatives, SFWMD established an initial set of
water and climate resilience metrics to track and document trends
and shifts in water and climate data monitored by SFWMD.
The SFWMD continues to assess these data to better understand the
current and predicted impacts of climate change on South Florida’s
ecosystems and water resources. This year’s chapter 2B focuses on:
• Groundwater levels and coastal saltwater intrusion trends in South
Florida — chloride data collected between 1990 and 2020 in the lower

River Watershed Restoration Project.
