Learn MoreDrainage Challenges in Lee County
Lee County's flood zone AE/VE areas require strict FEMA elevation plus 1-foot freeboard — drainage engineering must account for both stormwater management and floodplain compliance. Cape Coral's canal system, the most extensive residential canal network in the world, creates unique infrastructure integration challenges. Recent hurricane damage has driven significant demand for drainage system upgrades and rebuilds.
Cape Coral flood zone challenges
Cape Coral's SFHA zones and 50% substantial improvement rule require specialized drainage engineering. Hydrostatic flood vents have been mandatory since July 2020.
Hurricane damage rebuilding
Lee County was heavily impacted by recent hurricanes — drainage system upgrades are critical for rebuilds and must meet current code requirements.
Canal system complexity
Cape Coral has the most extensive residential canal system in the world (400+ miles) — drainage designs must integrate with existing canal infrastructure.
FEMA elevation requirements
1-foot freeboard above BFE is mandatory in flood zones AE/VE. Elevation certificates and drainage plans work together for compliance.
