Niles Rd Prime residential lot opportunity in Key Colony Beach, Monroe County, located at 0 Niles Rd, Key Colony, FL 33042. This approximately 9.2-acre property is situated in the Florida Keys with convenient access to nearby points of interest including Murray's Market (0.45 miles), Big Pine Key Boat Rentals (0.6 miles), Merrill Homes Inc (0.6 miles), and WWUS-FM Big Pine Key (1.85 miles). The lot is located in Flood Zone AE, a high-risk Special Flood Hazard Area (SFHA) with a 1/100 annual flood chance and established Base Flood Elevation (BFE), requiring the lowest floor to be elevated above BFE using flood-resistant materials, engineered foundations, mandatory flood insurance, and strict permitting with elevation certificates. Wetland impacts from Mangrove Swamp and Saltwater Marshes further restrict development, as these protected ecosystems generally require U.S. Army Corps of Engineers Section 404 permits, state environmental reviews, and mitigation; while the lot size suggests potential non-wetland pockets, overall development feasibility is low without extensive studies and approvals. Buyer must contact Monroe County Planning for an official Zoning Verification Letter to confirm allowable uses, setbacks, utility availability, and all development requirements. The property is available for a self-guided tour. Subleasing is not permitted. This lot is not available for rent or lease.
