New Utrecht BPL + Muni Lot

This site can hold about 110–140 homes under the zoning maximum for a qualifying residential site. The City's LIFT tracker lists 250. That is more than current zoning allows on the lots shown here, which can reflect lots not shown or a rezoning; this page uses current zoning only.

Floor area follows exactly from the Zoning Resolution. Homes are a range, because unit size and building efficiency are choices.

What binds first

Floor area

None of the earlier constraints on our list applies, so the maximum floor area the zoning allows is the limit.

What the neighborhood asked for

Brooklyn Community Board 11's formal requests to the City, from its annual Statement of Community District Needs and Budget Requests.

Brooklyn Community Board 11's FY2027 budget requests include none in the categories we track (housing, older adults, child care, libraries, health, community space, open space).

What gets in the way

Flags are flags, not verdicts. Each comes from a public layer, named in the sources.

  • Note

    Rezoning under discussion

    New Utrecht Library and Affordable Housing: rezoning assumed by the RFP (C4-5D along 86th Street, R6A along 85th Street, MIH area). Not filed. The figures above use current zoning, not the proposed zoning.

Nearest subway station: 18 Av (D), 350 ft in a straight line.

What this doesn't account for

This page shows what public data and the zoning text can tell us. These questions need information that isn't public, or a decision that isn't ours.

  • Public land use review (ULURP). Selling or leasing City land, or approving a housing project on it, generally goes through ULURP (community board, borough president, City Planning Commission, City Council), and this estimate does not presume the outcome.
  • Disposition of City property (Charter 384 / UDAAP). Transferring the land needs Mayoral approval under Charter Sec. 384 and, for HPD projects, usually Urban Development Action Area designation and project approval under NY General Municipal Law Article 16.
  • Environmental review (CEQR/SEQRA). Any discretionary approval, disposition or City funding triggers CEQR/SEQRA review, which can require mitigation (e.g. for hazardous materials, noise or historic resources) or reshape the project.
  • (E) designations. A lot with an (E) designation or environmental restrictive declaration for hazardous materials, air quality or noise cannot receive building permits until the Office of Environmental Remediation signs off.
  • Subsurface and site conditions. Unknown soil, rock, groundwater and contamination can shrink or eliminate cellars and add foundation and cleanup costs, and HPD requires every project to investigate and, if needed, remediate contamination.
  • Deed restrictions and reverter clauses. Land the City bought or sold may carry deed restrictions or reverter clauses limiting its use, which must be checked in title records (ACRIS) and DCAS's deed-restriction database.
  • Parkland alienation. If a site is municipal parkland, it cannot be sold or used for housing without an act of the State Legislature signed by the Governor.
  • Current occupants, uses and agency plans. Many City-owned lots are in active use or assigned to an agency, or have funded capital projects, and this estimate does not reflect relocation needs or agency plans (check COLP and the Capital Commitment Plan).
  • Mapped streets, easements and utilities. Mapped-but-unbuilt ('paper') streets, sewer and water easements and utility lines can take land out of the buildable area, and no permit may be issued for a building in the bed of a mapped street.
  • Street access. A lot with no frontage on a mapped street cannot get a building permit on its own and must be combined with a neighboring lot or have access mapped.
  • Landmarks review. Sites that are individual landmarks or inside historic districts need Landmarks Preservation Commission approval, which can limit demolition, height and bulk.
  • Flood-resistant construction. Sites in the 1% annual chance floodplain (or the 0.2% shaded X-Zone for critical facilities) must meet Building Code Appendix G, whose elevation and floodproofing rules can cost usable ground-floor and cellar space.
  • Airport height limits. Near JFK, LaGuardia and Floyd Bennett Field, zoning flight-obstruction surfaces cap building height, and tall structures anywhere need FAA notice.
  • State and federal funding conditions. Federal or State money brings its own requirements (e.g. HUD environmental review under 24 CFR Part 58, Davis-Bacon prevailing wages, Section 3 hiring) that can change cost, timing and program.
  • Zoning capacity is a ceiling, not a plan. The figures show what zoning allows, and actual HPD projects often build less, for example to fit neighborhood context, a community facility or funding limits.

Notes
Zoning on both confirmed lots (3063430031, 3063430064: R5 with C1-2 overlay) matches DCP's Carto and AGOL zoning data (dcp_mappluto and zoning polygons, 2026-09-24); ZoLa's own requests were not observed; our CSV had only 3063430064. Exact match: 47,588 sf (Lots 31 and 64), R5 with a C1-2 overlay; standard 1.50 gives 71,382 sf. Qualifying residential site 2.00 (in the Greater Transit Zone, 5,000 sf or more, frontage on 86 St, mapped 100 ft) gives 95,176 sf. CF 2.00 gives 95,176 sf. Homes 111/137/140.
