Public Ground

Plate 77 of 102BrooklynBrooklyn Community Board 16

Livonia Sites C1 and C4

This site can hold about 290–368 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 414. The City's LIFT tracker lists 281 homes.

The tracker's 281 is the approved plan: about 225 homes plus a superintendent's unit on Site C1 and about 54 plus a superintendent's unit on Site C4 (City Planning Commission, October 2022).

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.

  • Two separate vacant sites on Livonia Avenue

    The record covers two of the four Livonia4 development sites: Site C1 (Block 3813, Lot 115; 40,000 sq ft) and Site C4 (Block 3586, Lot 26; 10,017 sq ft), both vacant City-owned lots on Livonia Avenue (City Planning Commission, October 2022).

  • Approved 2022: disposition and rezoning to R7-2/C2-4

    On October 11, 2022 the City Planning Commission approved the disposition of Sites C1 and C4 to HPD-selected developers (C 220427 HAK) and a rezoning from R6/C2-4 and R6 to R7-2/C2-4 (C 220429 ZMK). HPD lists December 7, 2022 as the disposition approval date.

  • Site C1 is Site 142 of the Brownsville II renewal plan

    Site C1 is Site 142 of the Brownsville II Urban Renewal Plan. The plan's 2022 amendment (C 220428 HUK) changed the site's designated use from commercial to residential.

  • 2023 notice: City to condemn part of lot 115

    In January 2023 HPD gave notice of a hearing on acquiring by condemnation part of lot 115 (formerly Lot 14) within Site 142. None of the City records checked shows whether that acquisition was completed; City tax lot data list HPD as owner of the whole lot.

  • Encroachment issues with neighbors on Site C1 (2022)

    During the 2022 review, HPD told the City Planning Commission it was in contact with the Nehemiah homeowners whose property abuts Site C1, and that the encroachment issues involving those properties do not include homes.

  • Not yet closed as of HPD's August 2026 report

    HPD's Local Law 125 report (August 2026) lists a disposition approval date of December 7, 2022, shows the project as not closed, and gives the closing date as 'To be determined'.

  • 2025 building application for Site C1 lists 283 homes

    A new-building application filed with the Department of Buildings in April 2025 for 450 Powell Street (Site C1) proposes 283 dwelling units, more than the 225 plus a superintendent described in 2022; it showed objections in Department of Buildings data retrieved in September 2026. None of the Department of Buildings records checked shows an application for Site C4.

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

What binds first

Dwelling unit limit

The dwelling unit limit (ZR 23-52) holds the site to at most 368 homes, fewer than its floor area could hold at the smaller home sizes in the range. Floor area still limits the size of the building.

What the neighborhood asked for

Brooklyn Community Board 16's formal requests to the City, from its annual Statement of Community District Needs and Budget Requests.

What gets in the way

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

  • Note

    Partly in a Mandatory Inclusionary Housing area

    About 67% of the site is inside DCP's mapped Mandatory Inclusionary Housing area, where MIH options 1 and 3 apply: new housing on that part must include permanently affordable homes (ZR 27-131). The rest of the site is outside it.

  • Note

    Stormwater flooding in an extreme storm (2080s) on a small share of the site

    Less than 1% of the site (about 62 sq ft) shows nuisance flooding (4 in to 1 ft) on DEP's Stormwater Flood Map (extreme stormwater flood with 2080 sea level rise). It is shown for reference and not counted as a flood constraint on the site.

Nearest subway station: Rockaway Av (3), 980 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.

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 (50,017 sq ft), the zoning portions, the floor area (standard 175,217; with qualifying affordable or senior housing 250,585; community facility 325,111 sq ft), the homes (low 292, base 362, high 368), and the flags and what limits the site first.
