Our Process

How It Works

From initial assessment to permit-ready plans in Largo.

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.

Why Largo Properties Need Commercial Storm Water Management

Commercial properties in Pinellas County face the same space constraints as residential — there is no available land for surface retention. Underground stormwater vaults, green infrastructure, and innovative treatment systems are the only options for managing commercial stormwater in the densely developed peninsula.

Pinellas County Regulatory Note SWFWMD Environmental Resource Permits required. Tampa Bay Estuary Program and Gulf coast water quality standards apply to all commercial stormwater discharge.

Local Factors in Largo

  • Zero available land for surface retention on most commercial sites
  • Underground systems required
  • Bay and Gulf discharge water quality standards
  • Aging commercial stormwater infrastructure needs rehabilitation

Pinellas County's peninsula geography and dense development mean most natural soils have been extensively modified by fill and grading. Native soils are predominantly poorly drained Spodosols with very shallow water tables, compounded by the county's low average elevation of just 15 feet above sea level.

Pinellas County is the most densely populated county in Florida and among the most densely populated in the eastern United States. This density means there is virtually no available land for conventional surface stormwater retention — forcing engineers to use underground systems, green infrastructure, and creative design solutions that would be unnecessary in less developed counties. Every square foot of land has a competing use, making stormwater management a constant engineering compromise.

Local Cost Factors for Commercial Storm Water Management in Largo

Dense development requires underground stormwater systems that cost 3-5x more than surface ponds
Limited equipment access in dense neighborhoods increases construction difficulty
Virtually no vacant land available for conventional retention, driving innovative but expensive solutions
Waterfront property drainage requires corrosion-resistant materials and specialized design
