Columbia County Stormwater Management & Drainage Engineering

Yes, Columbia County requires drainage plans for development and redevelopment projects. Columbia County falls under the Suwannee River Water Management District (SRWMD), which administers Environmental Resource Permits (ERPs) for projects exceeding general permit thresholds. Professional engineering support is recommended for permit applications. Permits can be submitted through columbiacountyfla.com. CivilSmart handles the entire permitting process from design through approval.

Residential drainage design in Columbia County typically ranges from $3,000–$8,000 for standard properties, with complex projects (flood zones, retention/detention systems, large lots) ranging from $5,000–$15,000+. 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 regulatory requirements.

Columbia County drainage projects must comply with SRWMD Environmental Resource Permit (ERP) requirements under Chapter 62-330, F.A.C. Additionally, Columbia County enforces its own local stormwater ordinance that may impose stricter requirements than state minimums. Key local requirements include: LDC Article 8 flood management; BFE/100-year floor elevation. CivilSmart's engineers are experienced with all applicable Columbia County regulations.
