Prime residential lot opportunity in unincorporated Collier County, Florida, located at 238 Old Train Ln (ZIP 34137). The lot is located in Flood Zone AE, a high-risk 100-year floodplain that requires structures to be elevated above the base flood elevation (often via pilings, stem walls, or fill), significantly increasing construction costs; flood insurance is typically mandatory for financing, and local permits may impose strict elevation, drainage, and material standards to mitigate flood damage. No wetlands are present near the site, allowing for standard site preparation without additional federal or state permitting or mitigation measures. Zoned VR-ACSC/ST-CZO (Village Residential with ACSC/ST overlay), the property supports single-family detached homes by right. Limited duplexes/townhomes and ADUs may be conditional. Multifamily, mobile home communities, and high-density apartments are generally prohibited or require special exception/PUD approval. Density is governed by the comprehensive plan (typically 1-4 units/acre), though recent state laws (Live Local Act) may enable additional density overrides in certain cases. Buyer should verify all zoning, setbacks, utility availability, flood requirements, and development standards with the Collier County Planning & Zoning Department by requesting a Zoning Verification Letter. The property is available for a self-guided tour. Subleasing is not permitted. This lot is not available for rent or lease.
