Our Process

How It Works

From initial assessment to permit-ready plans in Callahan.

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.

Nassau County features poorly drained flatwoods Spodosols on the mainland with well-drained dune sands on Amelia Island. The transitional zone in Yulee between the island and inland areas has mixed drainage characteristics.

Nassau County's growth is concentrated in the Yulee corridor between I-95 and Amelia Island, where rural ranchland and timber tracts are being converted to residential subdivisions. This corridor sits on poorly drained flatwoods soils that require comprehensive stormwater engineering for every new development — the type of rapid land use conversion that creates the most dramatic changes in drainage patterns.
