The engineers at HCE have extensive experience with the unique stormwater issues and concerns found in South Florida.  We have helped our clients with their stormwater issues on numerous projects ranging from roadways and parking areas to stormwater site designs for well sites, pump stations, and water and wastewater treatment plants.

We understand the need to minimize flood and water quality impacts for our projects and the associated regulatory framework that governs their implementation.  HCE can provide planning, design, permitting, and construction services for a wide variety of stormwater related projects including storm sewer design for sites and roadways, detention and retention design for water quality treatment and flood attenuation, exfiltration trench design, stormwater master planning, bank, channel, and outfall stabilization, stormwater pollution prevention plan (SWPPP) design and inspection, and infrastructure inspection

Stormwater Analysis

HCE is knowledgeable with the stormwater regulations in South Florida and the required calculations and analysis that is required for implementation of a design.  The correct accounting of soil conditions, design rainfall volumes and distributions, runoff characteristics, attenuation storage, and water quality make up key components of a stormwater design.  For more complicated designs, our staff is also experienced with industry standard computer modeling programs such as ICPR 4 by Streamline Technologies, Inc. and HEC-RAS by the U.S. Army Corps of Engineers used for hydrologic and hydraulic modeling, including their integrations with ArcGIS and Civil3D.

Stormwater Permitting

The construction of stormwater improvements may require local approval from the municipality or drainage district as well as Environmental Resource Permits (ERP) from Florida Department of Environmental Protection (FDEP) and South Florida Water Management District (SFWMD).  In addition, the operation of the stormwater infrastructure by local municipalities or by utilities at a water and wastewater treatment plants require National Pollutant Discharge Elimination System (NPDES) permitting through the FDEP to minimize risk of harmful contaminants being discharged to the environment.  Our staff has obtained permits from various local, state, and federal agencies including SFWMD (ERP and Water Use Permits), Florida Department of Environmental Protection (ERP and NPDES permits), the U.S. Army Corps of Engineers for various wetland and surface water impacts.
