Residential Drainage Design & Solutions
Standing water in your yard is more than just an eyesore — it damages your lawn, breeds mosquitoes, and can impact your foundation. Our drainage engineering solutions address the root cause of water problems for Florida homeowners. From pool drainage to full-property stormwater design, our licensed professional engineers create PE-stamped plans that meet Florida’s jurisdiction-specific requirements and get approved the first time.

Our Residential Drainage Engineering Process
Initial Consultation & Assessment
- Property walk-through (1.5–2 hours) to diagnose water flow issues
- Evaluate slopes, soil conditions, and water flow patterns
- Identify root causes of drainage problems
- Review FEMA flood zone status and local regulatory requirements
Survey & Data Collection
- Boundary and topographic surveys (LiDAR or RTK GPS)
- Soil and geotechnical evaluation
- Existing drainage system documentation
- Setback, easement, and utility verification
Engineering Design
- Custom drainage layout with engineered blueprints
- Drain lines, catch basins, cleanouts, flow directions, and outlet strategies
- Material lists with quantities and specifications
- Hydraulic modeling (ICPR, HydroCAD) for pipe elevations and flow capacity
- Design storm performance verification
PE-Stamped Documentation
- PE-stamped grading and drainage plans
- Stormwater calculations and drainage statements
- Erosion control plans
- Permit-ready drawing packages
Permitting Support
- WMD, FEMA, and county code compliance review
- Permit application preparation and submission
- Agency liaison and comment response until approval
We engineer the solution. Our network of installers builds it.
When You Need a Residential Drainage Engineer
Not sure if you need drainage engineering? These common situations call for a licensed professional engineer.
New Home Construction
Building a new home that requires drainage plans for permit approval.
Room Additions or Expansions
Adding square footage changes site drainage patterns and may require engineering.
New Driveways, Patios, or Impervious Surfaces
Impervious surface additions can trigger stormwater calculation requirements.
Pool Installation
Especially in South Florida jurisdictions (Palm Beach, Broward, Miami-Dade) where drainage compliance is strictly enforced.
Property Flooding or Persistent Drainage Problems
Recurring flooding requires engineered solutions — not trial-and-error contractor fixes.
Grading Changes in High Water Table Areas
Modifying site grades near high water tables demands engineering calculations.
Renovations That Alter Site Drainage
Any renovation changing how water moves across your property may need engineering review.
Insurance Claim Requiring PE Documentation
Insurance companies often require PE-stamped documentation for flood damage claims.
Building Permit Rejected for Missing Drainage Plan
We produce the PE-stamped drainage plans needed to satisfy building department requirements.
Neighbor Construction Redirecting Water
Adjacent construction projects can redirect stormwater onto your property — engineering documents your situation.

Why Florida Drainage Engineering Requires Expertise
Florida’s unique geography creates drainage challenges that standard solutions from other states simply cannot address.
Flat Terrain
Most of South Florida is under 10 feet elevation — gravity-fed drainage is limited.
High Water Tables
Groundwater often just 1–3 feet below surface in coastal areas.
Intense Rainfall
50–65 inches annually, with tropical storms delivering 6–12+ inches in 24 hours.
Sandy Soils
Rapid water movement but poor structural stability — pipe misalignment common.
Regulatory Complexity
5 Water Management Districts, 67 counties, each with jurisdiction-specific requirements.
Pre-1984 Development
Older neighborhoods built before modern stormwater regulations.
French drains that work in other states often fail in Florida. PE-designed drainage systems account for Florida’s unique conditions — flat terrain, high water tables, and intense rainfall.

Pool Contractors: Drainage Engineering for Pool Installations
Every pool installation in South Florida is a potential drainage engineering project. Pool decks increase impervious surface area, and South Florida jurisdictions — Palm Beach, Broward, and Miami-Dade counties — are especially strict about drainage compliance.
What we provide for pool contractors:
- 1 Sealed site plans showing drainage patterns
- 2 Stormwater calculations (pre- vs. post-development runoff)
- 3 Soil compaction certification (Florida PE, Chapter 471)
- 4 Drainage statements for permit packages
- 5 Flood zone compliance statements where applicable
