Frequently Asked Questions

Frequently Asked Questions

A drainage engineer is a specialized civil engineer focused on water management — designing systems that control stormwater runoff, prevent flooding, and ensure regulatory compliance. In Florida, drainage engineers hold Professional Engineer (PE) licenses and can sign and seal plans required for permitting.
You need a drainage engineer whenever your project requires PE-stamped plans, permits, or regulatory compliance — including new construction, pool installations, flood zone work, and adding impervious surfaces like driveways and patios. A drainage engineer designs the system and secures permits; a contractor builds what the engineer designs.
Residential drainage design typically ranges from $3,000 to $8,000 for standard properties, with complex projects ranging from $5,000 to $15,000+. Commercial stormwater management starts at $10,000 for small sites. Every project begins with a custom quote.
Most Florida drainage projects require at least one permit. Environmental Resource Permits (ERPs) are required for projects that alter surface water flow or create impervious surfaces beyond local thresholds. NPDES stormwater permits are required for construction sites disturbing 1 or more acres. Most counties and cities also require drainage plans as part of building permit applications.
CivilSmart designs and permits drainage systems but does not install them. Our licensed professional engineers create PE-stamped engineering plans, and our network of installers handles physical construction.
CivilSmart serves all 67 Florida counties across all 5 Water Management Districts (SFWMD, SJRWMD, SWFWMD, SRWMD, NWFWMD).
