What this page counts as Harsimus Cove
We could not find an openly licensed official boundary for Harsimus Cove, so this page uses a census-based area. For this page, Harsimus Cove means the 2010 Census block groups whose center lies inside the National Register of Historic Places boundary of the Harsimus Cove Historic District (National Park Service) and inside the Jersey City city limits (U.S. Census Bureau). Every number below is for exactly those block groups (listed in “How these numbers were made”), so the edges are approximate and may include or leave out a few blocks people would call Harsimus Cove.

Past claims do not predict future flooding, and a neighborhood figure cannot tell you about one building. Look up the exact address on the FEMA Flood Map Service Center and get flood insurance quotes before you sign a lease or a contract.

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 these numbers were made
Area: the census-based definition above, using U.S. Census Bureau TIGERweb, 2010 Census Block Groups, National Park Service, National Register of Historic Places boundaries (NRHP polygons) and U.S. Geological Survey, Geographic Names Information System (GNIS) domestic names. Flood zone shares: the area 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 Hudson County (county code 34017), dataset as of September 8, 2026, retrieved November 7, 2026. Claims are counted for exactly the block groups that make up the area. Block groups used: 340170024002, 340170070003, 340170070001, 340170070002. 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.
