Flood zones street by street in Manayunk

The named streets in Manayunk, longest first, with how much of each street’s length inside Manayunk lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V). Length is the part inside Manayunk; the main zone is the FEMA zone covering most of that length. A street can cross several zones, so the zone at one address can differ from the street’s main zone: check the address above for that. 25 shorter streets are not listed.

Streets: U.S. Census Bureau TIGERweb, Transportation (primary, secondary and local roads). Flood zones: FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels, retrieved November 7, 2026.

Flood zones in Manayunk

Share of Manayunk’s mapped area (about 1.368 km²) in each FEMA flood zone, from FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels. Effective date of the FIRM panel(s) covering it (4207570086G, 4207570088G, 4207570089G, 42091C0386G, 42091C0388G, 42091C0389G): January 17, 2007, March 2, 2016.

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.

Flood insurance claims over time

Claims filed under the National Flood Insurance Program (NFIP) from the 2010 Census block groups that cover Manayunk. About 78% of the combined area of those block groups lies inside Manayunk, so the claim figures also reflect some nearby blocks. Only insured properties appear, so these counts understate total flooding.

How much is flood insurance in Manayunk?

The typical National Flood Insurance Program policy on single-family homes in Manayunk costs $1,212 a year: the median of 23 policies that started between September 1, 2025 and August 31, 2026. Half of them cost between $891 and $1,435. 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: 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: 421010214001 (99.9% of the block group is inside Manayunk), 421010215002 (93.8% of the block group is inside Manayunk), 421010210004 (52.0% of the block group is inside Manayunk), 421010210002 (98.5% of the block group is inside Manayunk), 421010213005 (35.6% of the block group is inside Manayunk), 421010214003 (100.0% of the block group is inside Manayunk), 421010214004 (100.0% of the block group is inside Manayunk), 421010214005 (99.9% of the block group is inside Manayunk), 421010214002 (99.5% of the block group is inside Manayunk), 421010215003 (45.6% of the block group is inside Manayunk). 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.
