Broward County Specific Factors
Several Broward County specific factors affect drainage system costs:
Natural Resources Protection Code Requirements
Coastal properties in Fort Lauderdale Beach, Hollywood Beach, and barrier islands face additional mangrove protection and environmental compliance requirements that increase costs.
Flood Zone Requirements
Coastal properties in Fort Lauderdale Beach, Hollywood Beach, and barrier islands face the strictest requirements, with systems needing to handle storm surge and flood events.
