Sheepshead Bay-Manhattan Beach-Gerritsen Beach, Brooklyn

The tax-lot records for this stretch of southern Brooklyn — Sheepshead Bay, Manhattan Beach, and Gerritsen Beach together — put federal flood mapping close to the center of the file: 19% of the roughly 9,700 parcels here sit inside a mapped Special Flood Hazard Area, the federal designation for the zone carrying the highest mapped flood risk. That figure describes where the map draws its line, not a claim about what has flooded or what will. Set against that exposure is a land-use pattern built overwhelmingly for one- and two-family living: 78% of recorded land use falls in that category, with multi-family walk-up buildings at 8% and vacant land at 4%. 90% of the area's lots carry some residential designation, and the roll counts 30,105 housing units across them.

Construction dates follow a similar prewar pattern: the median building here went up in 1935, and 52% of the recorded stock predates 1940, the cutoff this analysis uses for prewar construction. The postwar boom years of 1945 to 1975 added a further 29% of the buildings on file, a second wave that filled in blocks left open after the initial rowhouse era. Construction since 2000 accounts for just 5% of buildings, a quiet recent-construction share. Because so much of the stock predates both the boom and the current zoning code, most lots reflect building decisions made under rules no longer in force today.

Building-class records lean toward detached and semi-detached housing: 42% of buildings are recorded as one-family, 35% as two-family, and 7% as walk-up apartment buildings. Height sits low across the file, with a median of 2 stories and 0% of buildings recorded above 6 stories. Zoning headroom is present but not dramatic — 60% of lots carry some unused floor-area capacity on record, with a median residual FAR of 0.2. A residual FAR this size describes a narrow but real gap between recorded floor area and district maximum, not a plan, just a paper allowance. The districts governing this area are low-rise residential categories, written to keep new construction close to the existing rowhouse and detached-house scale.

Lot sizes run a typical range for this part of Brooklyn: a median of 2,156 square feet, with the 90th percentile reaching 4,750 square feet for the larger parcels. No lots here carry a recorded historic-district designation. The neighborhood borders Brighton Beach, Gravesend (East)-Homecrest, Gravesend (South), and Madison, each with its own recorded mix of flood exposure, building age, and lot scale. Behind every figure above — flood-zone status, building class, recorded floor area against district allowance — sits an individual tax-lot entry in the city's property records.
