M1-3/R8 Zoning District — New York City

Flood exposure reaches its most concentrated point in this batch on lots carrying this designation: 94% of its roughly 17 tax lots sit inside the mapped federal flood zone, among the highest shares recorded anywhere in this file. That is a statement about the regulatory boundary drawn on the federal map, not a ledger of which lots have actually taken on water. The file also carries no reliable year-built or floor-height coverage for these lots — an absence in the record rather than a claim that no history exists, and one that leaves this designation's construction era and building heights simply unrecorded here, unlike most other designations in this batch where at least a median year and height are on file.

What the file does record leans toward taller residential form: elevator apartment buildings lead the recorded classes at 35%, vacant land classifications follow at 24%, and walk-up apartment buildings add 6%. Land use is dominated by mixed residential-and-commercial parcels at 41%, with vacant land at 24% and multi-family elevator use at 6% — a designation where a substantial share of ground sits undeveloped on record even as elevator buildings anchor the built portion. Residential coding covers 47% of lots, and the file counts 2,318 homes, a sizable total that sits mostly in that elevator-building share rather than spread evenly across the designation's smaller footprint.

Lots run large here, a median of 18,617 square feet with the 90th percentile reaching 85,900 square feet — some of the biggest recorded ground in this batch, consistent with a mix of elevator buildings and undeveloped vacant parcels sharing the same designation. None of these lots, 0%, carry historic-district status on record. On the development side, 59% of lots record floor area below their allowance, with a median residual of 1.5 FAR — real but narrower room than some other designations in this batch show, on ground that already carries some of the largest recorded parcels here.

With age and height unrecorded here, the development and flood figures carry more of the descriptive weight for this designation than they do elsewhere in this batch, where a median year and a height figure usually fill that role instead. Flood status, building class, and lot size are each still tracked lot by lot across these 17 parcels; the floor-area rules that govern the designation, citations included, are in the tables above rather than in this summary of the recorded stock.
