Our Process

How It Works

From initial assessment to permit-ready plans in Islamorada.

1

Our engineers inspect your property's stormwater infrastructure, evaluate drainage performance, identify problem areas, and document existing system components. We photograph conditions and collect data needed for engineering analysis.

2

We obtain original permit documents, as-built drawings, and maintenance records from agencies and property files. This historical data reveals design intent, permitted capacities, and any modifications that may have occurred since construction.

3

Using field data and record documents, our Licensed Professional Engineers perform hydrologic and hydraulic analysis, design system improvements or new infrastructure, and prepare construction-ready drawings with detailed specifications.

4

We prepare and submit all required permit applications — including SFWMD ERPs, county building permits, and FDEP authorizations. Our team manages reviewer correspondence and resolves comments to keep approvals on track.

Islamorada Properties

Why Islamorada Properties Need Commercial Storm Water Management

Commercial properties in the Florida Keys face the same fundamental constraint as residential — porous limestone provides zero retention capacity, and conventional stormwater management is physically impossible. Commercial drainage requires injection wells, pump systems, and innovative treatment because the Florida Keys National Marine Sanctuary has zero tolerance for untreated stormwater discharge.

Monroe County Regulatory Note SFWMD permits plus FDEP Area of Critical State Concern review. Florida Keys National Marine Sanctuary protection standards. Commercial permits may require 6-12 months for full approval.

Local Factors in Islamorada

  • Porous limestone provides zero retention capacity
  • Marine Sanctuary zero-tolerance for stormwater pollution
  • Injection wells for stormwater disposal
  • ROGO limits commercial development but premium pricing offsets engineering costs

Key Largo limestoneKey Vaca sandMatecumbe marly silt loam

Monroe County soils are unlike anywhere else in Florida — the Keys sit on porous oolitic and coral limestone that allows rapid tidal flushing but provides no retention capacity for stormwater. Conventional retention ponds and French drains are ineffective because water passes through the rock matrix as fast as it enters.

Monroe County drainage engineering is fundamentally different from the rest of Florida. The porous Key Largo and Miami Limestone formations that form the Keys allow tidal water to move freely through the rock, meaning the "groundwater table" is essentially the tide level. When combined with elevations of 0-3 feet above sea level, this creates a situation where the water table can be at the surface during high tides regardless of rainfall. Engineers must design for a world where gravity drainage is unreliable and pump-assisted systems are the norm.

Local Cost Factors for Commercial Storm Water Management in Islamorada

Pump-assisted drainage adds $15,000-$50,000+ compared to gravity systems
Specialized limestone-adapted materials and techniques required
Island chain logistics increase material transportation and equipment mobilization costs
Highly specialized engineering commands premium pricing due to unique conditions
