What is a Baffle Box?
A Baffle Box is an underground stormwater
management device that uses barriers (or baffles)
to slow the flow of water, allowing sediment to
settle before water is released.
What is a Spillway?
A Spillway is a structure that allows the movement
of water between water bodies by use of gates.
UNDERGROUND WALL IN ACTION
Heavy rain events in 2022 demonstrated the success
of the underground seepage wall. On the bottom left
of the above photo, conditions in Everglades National
Park are wet.
On the top right, the nearby community is dry. Prior
to the installation of the seepage wall, the conditions
in both areas of the image would have been wet with
similar heavy rains.

UNDERGROUND SEEPAGE WALL
SUPPORTS EVERGLADES RESTORATION
AND MITIGATES FLOODING
On Dec. 12, 2022, the SFWMD and the USACE joined
other federal, state, and local officials to break ground on
the CEPP New Water Seepage Barrier Wall Project, which
extends the successful underground wall that was built as
part of the 8.5 Square Mile Area Seepage Wall Project. The
project supports ongoing restoration efforts to move water
south through the Everglades and into Florida Bay while
mitigating potential flooding impacts in communities
outside of Everglades National Park.
The CEPP New Water Seepage Barrier Wall Project adds five
miles of underground seepage wall along the L-357 Levee.
SFWMD completed the 2.3-mile first phase of the wall in
September 2022 and the project is already demonstrating
success. During heavy rain events, water that typically
would flood communities remained inside Everglades
National Park to support the park’s historic hydrology. By
supporting restoration flows of water through the Greater
Everglades Ecosystem, the new underground wall supports
the Combined Operating Plan (COP) and new infrastructure
being put in place throughout the Everglades that delivers
more water into Everglades National Park and Florida
Bay—two key areas that need increased flows of water.
OLD TAMIAMI TRAIL ROADBED REMOVAL PROJECT
COMPLETED SIX MONTHS AHEAD OF SCHEDULE
In 2021, Governor Ron DeSantis joined the DEP, SFWMD, USACE, and other
state and federal officials to celebrate the completion of the Old Tamiami
Trail Roadbed Removal Project, which was completed six months ahead of
schedule. This project is a critical Everglades restoration project to remove
nearly six miles of roadbed from Old Tamiami Trail to allow more water to
naturally flow south into Everglades National Park.
Old Tamiami Trail is a historic highway that was built across the Everglades
to connect Tampa and Miami in the early 1900s. By removing the roadbed,
the project helps restore the ecologically important sheet flow of water
south through the Everglades.
