New Haven committee gives proposed BD3 zoning biodiversity amendment leave to withdraw

The New Haven Board of Alders’ Legislation Committee voted to give OR-2024-0037, a proposed zoning amendment intended to support biodiversity in BD3 public plazas, leave to withdraw after city planning staff and the City Plan Commission said the proposal was incomplete and not ready for formal consideration.

Alder Ellen Kuppo, chair of the Legislation Committee, presided over the meeting. City Planning Director Laura Brown told the committee the proposal “includes revisions to a very small portion of the zoning ordinance” limited to the BD3 zone and that staff and the City Plan Commission recommended withdrawal because the measure lacked definitions and implementation guidance necessary for consistent enforcement.

The committee’s action removes the item from active consideration; the proponent may refile a more comprehensive proposal later. The committee closed the public comment period before the vote. A voice vote was taken and the motion passed.

Brown said the BD3 zone covers a narrow set of parcels near the downtown Crossing development and that the draft amendment would only affect public plazas within that zone. She told the committee that to implement a biodiversity standard effectively the city would need clearer definitions of what constitutes increased biodiversity and additional site requirements so staff could apply the rule consistently.

Brown also said city planning staff plan to rewrite relevant site requirements in the zoning ordinance after adoption of the Vision 2034 comprehensive plan, noting that a broader revision of site requirements — including requirements aimed at reducing reflective heat — would better align with the city’s long-term goals. She reported that the Yale School of the Environment had not submitted an official proposal to the city: “Students can use our letterhead to submit whatever they choose. We don’t know about this,” she said, summarizing the Dean’s office response.

Committee members who spoke supported the City Plan Commission recommendation to withdraw, saying the measure as drafted was a fragment of its stated intent and would require broader scope and formal notice under zoning rules to be corrected. One committee member said the item was “not ready for prime time” and encouraged the proponent to return with a more complete proposal.

The committee did not adopt any changes to the zoning ordinance at the meeting. City planning staff invited partners and proponents to work with staff on a more comprehensive revision aligned with Vision 2034.

The Legislation Committee adjourned after the vote.
