Impact analysis
Converting 34,000 square feet of asphalt to green space and reusing vacant industrial buildings could bring jobs and activity to the Calverton Grumman area.
The applicants and future workers at the facility get a clear, workable parking standard.
No nearby residents — the closest home is over half a mile away — though some board members voiced concern about the unspecified crop.

A developer wants to convert three old Grumman-area buildings into an indoor agricultural cultivation facility — possibly cannabis — and needs the ZBA to set a parking requirement since the code doesn't cover this use. The board wants more expert detail before deciding.
Planning Board - Aug 6, 2026
Residents cited Babylon's new limits on indoor agriculture facilities as a model Riverhead should consider, raising the broader question of whether warehouse-style farming belongs in residential and agricultural zones.
