County Flood Criteria 2022 A Miami-Dade County
About This Dataset
This dataset shows Miami-Dade County's official flood elevation requirements based on a 10-year storm event and projected 2060 sea level rise—essentially a map of how high buildings, roads, and seawalls must be built in different areas to stay safe from flooding. It's critical for anyone involved in construction, property development, or home improvement since county building codes require compliance with these elevation standards.
Why This Matters
- A homeowner or developer checking what minimum elevation their property's foundation or driveway must meet before submitting a building permit application
- A contractor or engineer designing a new residential development and needing to determine required fill heights and infrastructure elevations
- A real estate agent or buyer assessing flood risk and construction feasibility in different Miami-Dade neighborhoods

OBJECTID |
integer | CountyFloodCriteria: OBJECTID |
ELEV |
number | The elevation level in feet above sea level used to determine flood risk zones. This measurement helps identify areas that are more or less susceptible to flooding based on their height relative to predicted flood waters. AI |
SYMBOL |
integer | A numeric code that represents different flood risk categories or zones in Miami-Dade County. Each number corresponds to a specific flood designation (such as high-risk, moderate-risk, or minimal-risk areas) shown on flood maps. AI |
