Developer seeks wetland permit for Fairview Park Drive parcel; board asks for larger storm event design and water‑quality measures

At its July 1 meeting the Greenburgh Planning Board reviewed a wetland/watercourse permit application for a four‑acre commercial property at 102 Fairview Park Drive (case PB2537) that included parking reconfiguration, a new retaining wall and proposed subterranean cultex infiltration chambers to manage runoff.

Joe Fernandez, the project architect, told the board the proposed system includes 13 cultex units sized to hold roughly 13,000 gallons and that the design basis is 6.4 inches of rain (a 25‑year storm): “We based our design, 13,000 gallons of water on 6.4 inches, which is a 25 year storm,” Fernandez said. Board members and staff asked whether the design can be upgraded to a 50‑year standard; Fernandez acknowledged a 50‑year design would require roughly four additional cultex units and said the office would explore site constraints and space implications.

Members also flagged that portions of the work had been completed prior to permits, asked whether existing cultex include oil or sediment pretreatment devices, and requested a maintenance plan for the cultex units; Fernandez said the applicant has a semiannual maintenance contract and will provide it to engineering staff. Town engineers said they are currently satisfied with the submission but asked the applicant to provide a written update on water‑quality treatment and the feasibility of adding capacity for a 50‑year event.

The board indicated it would schedule the public hearing for July 15 if the applicant can supply the requested plan updates by July 8.
