LOMA and LOMR-F in Miami-Dade County, Florida
Miami-Dade County faces a convergence of flood hazards including hurricane storm surge, tidal flooding amplified by sea level rise, and inland flooding from an extensive canal system. The county's porous limestone geology allows groundwater to rise during king tides and heavy rainfall, reducing the effectiveness of traditional drainage infrastructure. Coastal neighborhoods from Miami Beach to Homestead are increasingly affected by sunny-day flooding events linked to rising sea levels.
