Our Process

How It Works

From initial assessment to permit-ready plans in Sebastian.

1

We visit your property to evaluate existing conditions, identify the source of water problems, assess soil types and permeability, and document elevations and flow patterns. This on-site assessment is the foundation of every successful drainage design.

2

Our survey team collects accurate elevation data, property boundary information, and locations of existing utilities and structures. This data feeds directly into the engineering design to ensure precise grading and pipe sizing.

3

Our Licensed Professional Engineers develop a complete drainage design including pipe sizing calculations, grading plans, detention/retention requirements, and construction details. Every design accounts for Florida's 25-year/24-hour storm event and local code requirements.

4

We prepare and submit all required permit applications to your local building department, SFWMD, or other agencies. Our team manages reviewer communication and addresses any comments to keep your project moving toward approval.

Sebastian Properties

Why Sebastian Properties Need Residential Drainage Design

Indian River County properties frequently sit on former citrus grove land with legacy agricultural drainage infrastructure that was never designed for residential stormwater management. Homeowners in Vero Beach and Sebastian experience flooding when old grove drainage ditches fail or when the spodic hardpan soil creates a perched water table during the wet season. Barrier island properties face additional coastal drainage complications with saltwater influence.

Indian River County Regulatory Note Indian River County Community Development requires drainage designs that protect the Indian River Lagoon — the most biologically diverse estuary in North America. Projects east of I-95 face enhanced water quality review.

Local Factors in Sebastian

  • Indian River Lagoon Central BMAP requires nutrient reduction for all stormwater discharge — Class II/III surface water designation imposes strict water quality treatment standards
  • Septic system prevalence on older residential lots contributes nutrient pollution to groundwater and Indian River Lagoon — Florida's 2030 septic conversion mandate drives active conversion program
  • Former citrus grove drainage systems need conversion to residential stormwater management
  • Spodic hardpan soils perch water at 2-3 feet depth during wet season
  • Indian River Lagoon water quality requirements affect all eastern county drainage

Indian River County features a classic Florida flatwoods soil profile with poorly drained Spodosols dominant. The spodic hardpan at 2-3 feet depth perches water and creates seasonal flooding. Barrier island soils are sandier with better natural drainage but face saltwater influence.

Indian River County's legacy as a citrus-producing region means many residential properties sit on former grove land with agricultural drainage infrastructure that may no longer be maintained or adequate for residential use. Converting grove drainage (designed for crop irrigation) to residential stormwater management is a specialized engineering challenge that requires understanding both systems.

Citrus grove drainage conversion requires assessment of existing agricultural infrastructure
Barrier island projects face higher mobilization costs and limited equipment access
Strict lagoon protection adds water quality treatment engineering requirements
