Engineering Excellence, Florida Expertise

As professional engineers who understand the science behind drainage and the numerous agency requirements, we deliver solutions that work — and get approved.

We understand challenging site conditions and tough building department reviews. Florida's flat terrain, high water tables, and intense seasonal rainfall create drainage challenges that off-the-shelf solutions cannot solve. With 20+ years of experience across all 67 Florida counties, we engineer drainage systems designed for your specific site, your specific jurisdiction, and Florida's demanding conditions.

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.
Hire a drainage engineer when you need PE-stamped plans for permits, you’re building new construction, adding impervious surfaces (driveways, patios, pools), working in flood zones, or facing regulatory compliance requirements. Engineers design the system. Contractors build what engineers design.
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.
It depends on the scope of your project. Environmental Resource Permits (ERPs) are required for projects that alter surface water flow or create impervious surfaces beyond thresholds. NPDES stormwater permits are required for construction sites disturbing 1 or more acres. Most counties and cities 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).
