Rosedale, Queens

Of the ten neighborhoods profiled together in this section of Queens, Rosedale carries the largest share of lots inside the federally mapped floodplain: 10% of its roughly 5,600 tax lots, on record as of the current map. That figure describes regulatory exposure, not a history of flooding — but it is the highest reading in this cluster, well above the 0% many neighboring profiles show. That single figure sets Rosedale apart from several of its immediate neighbors, where the same measure reads at zero, and it is worth reading alongside the neighborhood's otherwise fairly typical building-class and land-use figures rather than in isolation.

Development headroom in Rosedale is the tightest recorded in this group: 86% of lots carry floor area below their current district allowance — the lowest share among these ten neighborhoods — at a median residual of 0.3 FAR, meaning the typical Rosedale lot has less room left under current rules than most of the neighborhoods around it, even though the great majority still carry some unused capacity.

The median building here dates to 1950, with 62% of the recorded stock built during the 1945-to-1975 postwar boom and 27% predating 1940; 5% dates from 2000 or later. One-family homes make up 49% of recorded building classifications, two-family homes 39%, and 4% carry a vacant-land classification. Land-use records show 88% of lots in one- and two-family residential use, with 4% vacant and 4% multi-family walk-up. Those shares describe a neighborhood whose recorded construction, like several of its neighbors, concentrated heavily in the postwar decades rather than before or since.

Lots run to a median of 4,000 square feet, with larger lots topping out at 5,365 square feet, and building heights hold at a median of 2 stories with no recorded structure above 6 stories. Residential use covers 93% of lots, and the roughly 5,600 parcels carry 8,124 housing units on record. That fairly typical lot and height profile, set against the neighborhood's higher flood and lower headroom figures, suggests those two more unusual readings are specific to Rosedale's regulatory file rather than to its physical building stock.

Rosedale borders Cambria Heights, Laurelton, and Springfield Gardens (South)-Brookville, two of which — Laurelton and Springfield Gardens (South)-Brookville — also carry recorded flood-map shares of their own, unlike several other neighborhoods in this cluster where the flood figure reads a flat 0%.
