The Greenwich Planning and Zoning Commission voted unanimously Feb. 25 to approve a trio of applications from the 1 American Lane applicant: a zoning text amendment, a zoning map amendment and final site plan and special permit for a residential development on 154.53 acres in the BEX‑50R zone.

Commissioners approved a zoning text amendment (file PLPZ2024‑638) that clarified timing of payments to the Town’s Affordable Housing Trust Fund and allowed up to 3% of proposed units to be attached groupings of four or five units. Next the commission approved a zoning map amendment (file PLPZ2024‑379) rezoning 154.53 acres from BEX‑50 to BEX‑50R; staff noted WestCOG had commented that the proposal was inconsistent with the regional plan of conservation and development, but the commission found the change consistent with the town’s 2019 Plan of Conservation and Development guiding principles and objectives.

Finally commissioners approved the final site plan and special permit (file PLPZ2024‑410) to construct 98 residential units, upgrade the on‑site wastewater treatment plant, expand a conservation easement, install stormwater management and landscaping, and make a contribution to the Greenwich Affordable Housing Trust Fund in lieu of constructing some units. The commission’s approval included conditions requiring the applicant to secure full state and local approvals for wastewater treatment plant upgrades before a zoning permit is issued, to return to the commission if required changes exceed what the applicant has represented, and to submit an open‑space declaration acceptable to planning staff and the law department for recording on the town land records.

The commission’s staff summary records state that the project will require Connecticut Department of Energy and Environmental Protection (DEEP) approvals for the wastewater plant expansion and that the New York City Department of Environmental Protection reviewed and raised no concerns about impacts to the New York City drinking‑water watershed. The commission also noted wetlands agency approvals (permits dated 06/2024 and 01/27/2025) that include conditions requiring returning to the wetlands agency for review of detailed construction plans affecting the wastewater treatment facility.

The motion to approve the site plan and special permit included multiple standard conditions: final landscaping and drainage revisions to address DPW and consulting‑engineer comments, showing three school bus stop locations on the final plan per the public schools superintendent, meeting generator noise and fuel‑supply code requirements, returning to ARC electronically to close previously noted design bullets, and securing all necessary state and local permits for well relocations and wastewater upgrades prior to zoning permit.

Commissioners Alban, MacRae, Jones, Lowe and Yeske voted in favor of each application. The file notes record the commission’s finding that the intervenor’s environmental claims did not demonstrate unreasonable environmental harm within the commission’s statutory authority and that any remaining concerns tied to state permits or other agencies would be addressed through conditioning and through those agencies’ reviews.

The approvals are conditioned on the applicant obtaining required DEEP and other state permits for the wastewater treatment plant; the commission’s staff memo also lists outstanding DPW drainage and traffic comments that must be addressed before issuance of a zoning permit.

The commission recorded its votes on the record: the text amendment passed “5‑0,” the zoning map amendment passed “5‑0,” and the final site plan and special permit passed “5‑0.”
