11. A-1 Flow Equalization Basin (FEB)
The A-1 FEB project is a part of
the overall Everglades restoration
effort and will support the
operations of STA-3/4 and STA-
2/Compartment B. The A-1 Flow
Equalization Basin (FEB) will be
an approximately 15,000 acre
basin that will be utilized to
attenuate peak storm water runoff
flows being delivered to the STA-
3/4 and STA-2/Compartment B
from the North New River Canal
(NNRC) and the Miami Canal.

12. G-716 Three Gate Structure
 During high flow events from the C-51 West Basin and when
there is capacity for storage in the L-8 FEB or when STA 1E
is receiving optimal flows, water will be diverted through S-
375 & G-716 to the G-311 Structure, the addition of G-716
Structure is required. G-716 Structure will be designed for a
capacity of approximately 2,400 cfs.
G-716

13. L-8 Flow Equalization Basin

14. L-8 Divide Structure, G-541
This Project includes the design
and construction of a fully
automated, reinforced concrete
water control structure to be
located within the L-8 Borrow
Canal, east of the L-8 FEB. The
structure will be designed to
function within the current
o[perational criteria for the L-8
Borrow Canal, while facilitating
flows from the STA-1 Inflow Basin
into the L-8 FEB. The structure will
also be used to allow flows to be
directed south from the L-8 FEB
into the STA-1 Inflow Basin.

15. S-5AS Divide Structure
 Under the Restoration Strategies
Program S-5A Basin a& the C-
51 West Basin runoff will be
directed north through S-5AS to
the L-8 FEB. With the
implementation of this Program,
the use of the S-5AS structure
will increase and therefore will
require upgrades to ensure more
efficient operations and
increased use at higher stages
and flow rates.

16. Everglades Restoration –
Long-Term Solutions
Central Everglades
Planning Project
 Streamlined planning effort to
get projects in the heart of the
Everglades system readied for
Congressional authorization
and appropriation within 2 years
SFWMD Commitment
 Provide technical expertise
 Modeling
 Plan formulation
 Facilitate public participation
 Serve as local sponsor

20. MODELING STRATEGIES
Hydrologic models (computer simulation) are
planning tools to facilitate the evaluation
of alternative restoration approaches
Conveyance and distribution
available for water to go where
needed, when needed
Enough clean water so system is
not over-drained in WCA-3
Maintain clean water in the natural
system but do not impact existing
flood management
