Preliminary plat approval is first stage of subdivision approval process. Preliminary plat shows: proposed lot layout, roads, utilities, infrastructure, environmental constraints. Planning board reviews: compliance with zoning, infrastructure adequacy, environmental issues, design standards. Approval is conditional: subject to conditions (road improvements, drainage, environmental mitigation). Conditions must be satisfied before final plat approval. Timeline: preliminary approval typically 1-3 months. Benefits: preliminary approval gives project momentum, authorizes engineer to proceed with detailed design, identifies issues early. Challenges: conditions might be extensive (expensive), design changes might be required. Preliminary approval doesn't guarantee final approval: if conditions can't be met, project might not proceed. Financing: lenders sometimes advance funds after preliminary approval (developer has approval momentum). Understanding preliminary approval: it's conceptual approval, not recording approval. Final plat approval comes after conditions are satisfied.
Pro Tip
Carefully review preliminary approval conditions. Budget to satisfy them all before moving to final approval. Some conditions are expensive; others are deal-breakers. Address them early rather than discovering late they're impossible.
Example
Subdivision preliminary plat approved with condition that developer upgrade adjacent road and install drainage system before final approval.
