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.

What to ask your agent

  • Ask the agent how old the roof is.
  • Ask whether a wind-mitigation discount is available for this house.

How these numbers were made

Neighborhood boundary: Philadelphia Neighborhoods by Robert Cheetham (Azavea), published on OpenDataPhilly, licensed CC BY 4.0 (CC BY 4.0). 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 November 7, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Philadelphia County (county code 42101), dataset as of September 8, 2026, retrieved November 7, 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: 421010276004 (100.0% of the block group is inside Fern Rock), 421010276001 (98.8% of the block group is inside Fern Rock), 421010276002 (100.0% of the block group is inside Fern Rock), 421010276003 (100.0% of the block group is inside Fern Rock). 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.
