EXECUTIVE SUMMARY
Joint presentation on Rainy Season Readiness by the South Florida Water Management
District/Big Cypress Basin and County Staff,
OBJECTIVE: To update the Board of County Commissioners (Board) on the current conditions of
the area's surface water management system and rainy season/hurricane preparedness.
CONSIDERATIONS: With the beginning of the 2010 hurricane season, staff from the South Florida
Water Management District's (SFWMD) Big Cypress Basin and Collier County Stonnwater are
providing a briefing to the BCC on several stonnwater management issues. Protection from flooding
is a shared responsibility. The SFWMD, County and City government as well as and residents of
Collier County, all playa critical part in management of the precious water resources of the area.
The path stormwater runoff follows from a neighborhood to its final destination can be long and
arduous. During the rainy season ground water levels rise, the soil's capacity to absorb rainfall wanes,
and stormwater runoff begins. Some runoff is temporarily stored in public areas, yards and swales.
Excess water drains to community lakes and em-site ponds. Maintenance and upkeep of the
community water management facilities are typically the responsibility of homeowner associations.
Water then drains from the community or "tertiary" systems via pipes, swales, and ditches to the
"secondary" system. Maintenance of the secondary system is typically the responsibility of local
government. Responsibility includes the design, construction, and maintenance and operation of water
conveyance and control facilities. The South Florida Water Management District operates and
maintains the "primary" system which typically includes all thc larger downstream canals and water
control structures.
Weather conditions and water levels are monitored around the clock by SFWMD. Open lines of
communication between District staff and staff oflocal governments provide for frequent and essential
transfer and sharing of data throughout the stonn scason. Floodgates are opened and water levels are
lowered to the greatest extent possible in anticipation of heavy rains to accommodate direct rainfall
and inflows fi'om the secondary systems. Year-round maintenance programs performed by local
government and the Water Management District assure peak performance of all facilities under
emergency conditions.
