Coastal A Zone C Miami-Dade County
About This Dataset
This dataset maps Miami-Dade County's Coastal A flood zones—areas vulnerable to storm surge, high tides, and tsunamis rather than river flooding. It's essential for homeowners, developers, and business owners to understand flood risk and insurance requirements in their area, and helps the county process building permits and enforce flood safety regulations.
Why This Matters
- A homeowner considering buying a beachfront property checks whether their address falls in a Coastal A Zone to understand flood insurance costs and building restrictions
- A developer planning a new commercial project uses this map to determine if coastal flood-resilient construction standards apply to their site
- A property appraiser reviews flood zone boundaries when assessing home values and insurance requirements for mortgage lenders
