515 Blake Avenue (Buildings C and D)

This site can hold about 275–346 homes under the zoning maximum for qualifying affordable housing. The top of that range is set by the dwelling unit limit (ZR 23-52); qualifying senior housing is exempt from it and could hold up to about 389. The City's LIFT tracker lists 254 homes.

The tracker's 254 is the approved plan's Building C (79 homes, now built) and Building D (175 homes).

What City documents say

Facts from City documents that bear on the figures below. Each is quoted in the sources, and each speaks as of its document's date.

  • Part of one approved large-scale development

    Buildings C and D are part of a four-building large-scale general development on former Block 3766, Lot 1 that shares a single zoning lot, so a lot-by-lot figure is not the legal limit. The 2019 special permit (C 190421 ZSK) lets community facility floor area move across zoning district lines within the shared zoning lot.

  • 2019 approvals set the program: 79 + 175 homes

    The City approved the land disposition, rezoning, inclusionary housing text and special permit in 2019 (Council, December 10, 2019). The plan gives Building C 79 homes and Building D 175 homes.

  • Building C (79 homes) is already built

    A certificate of occupancy for the 79-home Building C at 314 Hinsdale Street was first issued on January 14, 2026 and most recently renewed on September 14, 2026. Only Building D remains to be built; MapPLUTO records Lot 54 as vacant land with no buildings.

  • Urban renewal plan was set to expire March 6, 2026

    In 2019 the City Planning Commission said the site was coterminous with Sites 101A/110B of the East New York I Urban Renewal Area, designated for residential use, and that the plan would expire on March 6, 2026.

  • Disposition approved in 2019; lots held by HELP HDFCs

    HPD's Local Law 125 report (July 2026) gives December 10, 2019 as the City Council and Mayoral approval date for disposing of these lots. MapPLUTO records Lot 42 as owned by HELP Hinsdale C Housing Development Fund Corporation and Lot 54 by HELP 515 Blake Avenue Housing Development Fund Corporation.

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

What binds first

Split zoning (needs a closer read)

2 lots are divided between zoning districts (R6A and R7D), each covering at least a tenth of each lot. Floor area is computed portion by portion. Where the district line falls on the lot shapes what can go where, so the figures above deserve a closer read against the zoning map.

What the neighborhood asked for

What gets in the way

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

  • Hazard

    Stormwater flooding in an extreme storm (2080s)

    DEP's Stormwater Flood Map (extreme stormwater flood with 2080 sea level rise) shows nuisance flooding (4 in to 1 ft) and deep and contiguous flooding (1 ft or more) on about 3% of the site (1,430 sq ft).

  • Caution

    A listed lot already has a new building

    Block 3766 lot 42 has a building on record with 286,100 sq ft of gross building area and 79 homes, completed around 2025 (MapPLUTO; gross area includes space zoning does not count). City Planning's 2019 report gives Building C about 58,400 sq ft of residential floor area. The 286,100 sq ft MapPLUTO records is more than the zoning maximum shown here for both lots together, so the recorded building area appears to be an error. Zoning counts floor area already on a lot toward its maximum, so the figures above are the most the land could hold in total, not what could be added while that building stands. The City's tracker may already count homes in a recently finished building.

  • Caution

    Not recorded as City-owned

    MapPLUTO records block 3766 lot 42 as fully tax-exempt (owner recorded as “HELP HINSDALE C HOUSING DEVELOPMENT FUND CORPORATI”). It records block 3766 lot 54 with no ownership type, not as City property (owner recorded as “HELP 515 BLAKE AVENUE HOUSING DEVELOPMEN T FUND COR”).

  • Caution

    Split zoning

    2 lots are divided between zoning districts (R6A and R7D), each covering at least a tenth of each lot. Floor area is computed portion by portion.

  • Note

    In a Mandatory Inclusionary Housing area

    MIH option 1 applies, so new housing here must include permanently affordable homes (ZR 27-131).

Nearest subway station: Sutter Av (L), 870 ft in a straight line.

What this doesn't account for

Public data and the zoning text answer the questions above. These need information that is not public, or a decision that belongs to the City.

  • 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
On September 25, 2026, the MapPLUTO records and zoning district map behind this page were compared with DCP's live MapPLUTO (26v2) and zoning district layers for both of its lots; every compared field and district boundary matched. A separate calculation, written from the method page and run on the same downloaded City data on September 25, 2026, reproduced both lots and their area (53,917 sq ft), the zoning portions, the floor area (standard 186,415; with qualifying affordable or senior housing 235,534; community facility 186,415 sq ft), the homes (low 275, base 340, high 346), and the flags and what limits the site first.
