Seminole County Stormwater Management & Drainage Engineering

Yes, Seminole County requires drainage plans for development and redevelopment projects. Seminole County falls under the St. Johns River Water Management District (SJRWMD), which administers Environmental Resource Permits (ERPs) for projects exceeding general permit thresholds. Professional engineering support is recommended for permit applications. CivilSmart handles the entire permitting process from design through approval.

Drainage engineering in Seminole County costs $3,000–$8,000 for standard residential properties and $5,000–$15,000+ for complex projects involving flood zones, retention/detention systems, or large lots. Commercial stormwater management starts at $10,000 and scales with project complexity. Every CivilSmart project begins with a free custom quote based on your specific property and SJRWMD regulatory requirements.

Seminole County drainage projects must comply with SJRWMD Environmental Resource Permit (ERP) requirements under Chapter 62-330, F.A.C. Additionally, Seminole County enforces its own local stormwater ordinance that may impose stricter requirements than state minimums. Key local requirements include: Wetland Overlay Zone; FL Statutes Chapter 163 alignment. CivilSmart's engineers are experienced with all applicable Seminole County regulations.
