Brady Ranch & Grassy Island: Two flow equalization basins |
(FEBs) located on District-owned properties that will capture |
peak stormwater flows and assist in hydrating adjacent STAs |
for improved nutrient removal. Design is underway and |
construction is expected to commence in 2025. |
S-191 Innovative Technology Treatment: Nutrient load reduction |
project to remove phosphorus from the S-191 Basin before it |
enters Lake Okeechobee. Design was recently completed, and |
the project is expected to be operational in 2023. |
Kissimmee Headwaters Revitalization Schedule: Continued |
development of the revised regulation schedule is for the |
restored portion of the Kissimmee River. Final schedule is |
anticipated in 2026. |
Taylor Creek Nubbin Slough (TCNS) 214 Storage and |
Treatment: Capture and attenuate excess stormwater from |
Williamson Ditch into a shallow water storage feature. |
Planning and design began in 2022. |
