Premier City Island Development Opportunity: At 2.75 acres (120,042 SF), this lot size provides unrivaled scale for the neighborhood, allowing for a master-planned development rather than a simple infill project. The site can yield approximately 90,032 buildable SF as-of-right, with potential for up to 120,042 buildable SF as a Qualified Residential Site (485-x), Senior Housing, or commercial development. Flexible Zoning Options: The R3A / C2-2 (CD) designation permits detached single-family homes, commercial uses, or community facilities as-of-right. Expanded Marina Potential: Opportunity to leverage 149,928 SF of land under water via recorded riparian rights to expand the existing 80-slip marina to a ~120-slip configuration, providing a significant value-add for a waterfront destination or private residential boat club. Currently the Marina Gross Income is $392,000. City Island serves as a premier residential destination, offering a unique waterfront lifestyle that is highly sought after but supply constrained. Located near local bus routes (Bx29) that connect directly to the 6 Subway line at Pelham Bay Park. Minutes away from “Restaurant Row,” local yacht clubs, and nature preserves
