Polk County Stormwater Management & Drainage Engineering

Yes, Polk County requires drainage plans for development and redevelopment projects. Polk County falls under the South Florida Water Management District (SFWMD), 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.

Residential drainage design in Polk 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.

Polk County drainage projects must comply with SFWMD Environmental Resource Permit (ERP) requirements under Chapter 62-330, F.A.C. Additionally, Polk County enforces its own local stormwater ordinance that may impose stricter requirements than state minimums. Key local requirements include: 600+ miles of pipes maintained; SB 180 limits post-hurricane regulation changes. CivilSmart's engineers are experienced with all applicable Polk County regulations.
