What the zones mean
- Zone AE (and A, AH, AO)
- High-risk: part of the Special Flood Hazard Area (SFHA), the area FEMA maps as having a 1-percent chance of flooding in any given year (the “100-year” or base flood). AE areas have a mapped base flood elevation.
- Zone VE (and V)
- High-risk coastal areas, also in the SFHA, where the base flood is expected to bring additional hazards from storm waves.
- Zone X (shaded)
- Moderate hazard: between the limits of the 1-percent and the 0.2-percent-annual-chance (“500-year”) flood.
- Zone X (unshaded)
- Minimal hazard: outside the SFHA and higher than the 0.2-percent-annual-chance flood elevation. Minimal is not zero: flood claims are filed from X zones too.

How much is flood insurance in Old San Juan?
The typical National Flood Insurance Program policy on single-family homes in Old San Juan costs $898 a year: the median of 25 policies that started between August 1, 2025 and July 31, 2026. Half of them cost between $699 and $1,018. That is the full amount paid for the year, the premium plus FEMA’s fees and surcharges, and every one of these policies is priced under Risk Rating 2.0. A quote for one building can be far from this: its elevation, foundation, age, coverage and deductible all change the price. Private flood insurance is not included.

How these numbers were made
Neighborhood boundary: City of Miami, Miami Neighborhoods (ArcGIS feature service). Flood zone shares: the neighborhood polygon intersected with FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels, area computed in an equal-area projection; retrieved October 24, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Miami-Dade County (county code 12086), dataset as of September 8, 2026, retrieved October 24, 2026. A 2010 Census block group is counted for a neighborhood when at least 25% of the block group lies inside the neighborhood, or at least 25% of the neighborhood lies inside the block group. Block groups used: 120860026004 (86.4% of the block group is inside Old San Juan), 120860026003 (98.3% of the block group is inside Old San Juan), 120860026002 (83.8% of the block group is inside Old San Juan), 120860026001 (38.1% of the block group is inside Old San Juan). Neighboring pages can share a block group, so their counts can overlap. Paid totals add building, contents and Increased Cost of Compliance payments and are not adjusted for inflation; a claim whose FEMA record shows a negative payment (an adjustment) counts as zero.
