M1-5A/R8 Zoning District — New York City

Every one of the roughly 14 tax lots carrying this designation, 100%, sits inside the mapped federal Special Flood Hazard Area — the most complete recorded flood overlap of any designation in this family. That is a statement about the regulatory boundary drawn on the federal map rather than a ledger of which parcels have actually taken on water, but on a footprint this small, it means the flood map touches every single lot carrying the designation without exception, a completeness that no other designation in this family's file can match. Even the largest, most citywide footprints elsewhere in this comparison set fall well short of that full coverage.

The age record centers squarely on the postwar era: the median construction year is 1953, and 58% of recorded buildings fall inside the 1945-to-1975 postwar boom — one of the higher boom-era concentrations in this comparison set — against 25% predating 1940 and just 8% built since 2000. Factory and industrial buildings lead the recorded building classes at 36%, warehouses follow at 14%, and vacant land classifications tie them at 14% as well, a working-and-undeveloped mix rather than a residential one, and one that reads as ground still shaped largely by its midcentury industrial buildout. Little has been added to that base in recent decades on the evidence of the 8% since-2000 figure.

Land use tracks that same pattern: industrial-and-manufacturing use covers 50% of these 14 lots, transportation-and-utility use another 14%, and vacant land use a further 14%. Just 7% of lots are coded residential, and the file counts 208 homes across the footprint — a small residential presence on what the records otherwise describe as working, flood-exposed ground. Lot sizes run large, a median of 16,000 square feet with a 90th percentile of 52,613 square feet, scale consistent with the industrial buildings the class file shows leading and among the larger typical lot sizes recorded in this family.

The development file shows one of the widest recorded gaps in this family: 93% of these lots record floor area below their allowance, with a median residual of 4.9 FAR — a wide margin that sits alongside, rather than in place of, the complete flood-zone overlap already on record. None of the 14 lots, 0%, carry historic-district status on record. Each lot's own page carries its specific recorded figures, and the rules tables above set out the governing floor-area numbers with their citations for anyone checking a specific parcel.
