Mount Vernon planning board presses for independent environmental review as neighbors oppose two‑lot subdivision at 55 Pondfield Parkway

On Sept. 9, 2025, the Mount Vernon Planning Board heard extended public comment and argument on an application by Mad Properties LLC to subdivide 55 Pondfield Parkway — a 20,000‑square‑foot lot — into two 10,000‑square‑foot parcels and later construct one single‑family home on each new lot. The board did not vote to approve the subdivision and instead instructed staff to pursue a limited independent environmental review and to gather related municipal records before taking a formal action.

Neighbors urged the board to require independent studies and more review because of concerns about bedrock removal, stormwater and sanitary infrastructure, demolition‑stage hazardous materials and proximity to Hunt’s Woods and Laurel Brook. The applicant’s attorney, Mark Blanchard, told the board the proposal is for two zoning‑compliant single‑family lots and argued many issues would be regulated through building‑permit reviews. Community counsel and several residents countered that the application’s supporting materials were incomplete and that independent analysis was needed.

The board’s discussion focused on what specialist work La Bella — the firm the city council previously authorized — should perform. Planning staff and board members agreed to ask La Bella to complete the flora and fauna review and a targeted water‑quality/stormwater assessment for Laurel Brook; the board also asked staff to obtain the building‑department demolition/hazardous‑materials file (demo permit DML24‑4 was cited in the meeting) and to request engineering and Department of Public Works comments on water/wastewater and stormwater management. No final approval or denial of the subdivision was taken at the meeting; the board’s next procedural step was to request those studies and related municipal records and to schedule the matter for a future hearing once the information is available.

Applicant’s case: Attorney Mark Blanchard told the board the project would create two zoning‑compliant single‑family lots and that the demolition contractor submitted a hazardous‑materials report when applying for demolition permits; he said the building department issued a demolition permit and that typical building‑permit conditions and inspections would address hazardous materials, stormwater retention and bedrock‑removal methodology. Blanchard urged the board to focus on the application materials and noted that, under the city’s prior determinations, subdivision review is an “unlisted action” under SECRA, not a Type 2 action. He asked the board to treat the matter as a standard unlisted SECRA review and not to delay the project further.

Community case: Neighbors and their counsel pressed for independent study. The community attorney cited the need for an impartial third‑party review because they said earlier materials were inconsistent or superficial (the transcript records disagreements about the accuracy of previous environmental filings and photographs). Residents described prior flooding, ongoing stormwater concerns tied in public conversation to a federal consent decree and to recent regional water‑quality problems. Neighbors also raised possible impacts from excavation and rock removal on nearby foundations and the wooded area behind the parcel.

Scope and next steps: At the meeting the transcript records a La Bella contract figure of $23,750 with line items discussed in public (example line‑item amounts mentioned in the meeting: depth to bedrock $4,500; impacts to habitat, flora and fauna $3,500; hazardous materials related to demolition $8,500; wastewater/water usage $5,000; Laurel Brook water quality $2,250). Planning staff and the applicant agreed to coordinate to remove from La Bella’s scope those items already documented to the satisfaction of the building department and other city reviewers (for example, the hazardous‑materials/demolition paperwork the applicant says is already in the building‑department file under demo permit DML24‑4). The board asked staff to work with La Bella to complete the flora/fauna and Laurel Brook water‑quality pieces on an expedited schedule and to request engineering and DPW comments on stormwater and sanitary service. Planning staff said they would attempt to have La Bella’s work and the requested municipal responses available for the board’s October meeting.

No vote or binding action on the subdivision was taken; the board separated factual review (requested studies and municipal records) from discretionary approval. The board instructed staff and counsel to return the item to the agenda after the independent studies and the building‑department and engineering responses are on the record.

A number of residents said they wanted all documents and consultant reports posted on the city’s project portal so the public could review them in advance. The board asked the applicant and staff to ensure required documents appear in the portal and to notify interested parties when the new materials are available.
