Creates the Eastchester creek intermunicipal economic revitalization agency

This bill establishes the Eastchester Creek Intermunicipal Economic Revitalization Agency, a joint body for the city of Mount Vernon and village of Pelham Manor. It defines a specific geographic area (231 acres in Mount Vernon and a triangular zone in Pelham Manor) where the agency will operate to advance economic development. The bill authorizes Pelham Manor to adjust its local sales tax rate within this designated area to match Mount Vernon's rate, creating uniform tax treatment for businesses and residents in the shared zone. The agency must follow existing zoning laws and coordinate with both municipalities on land use decisions.
