Storm Drainage & Retention Construction in Savannah: local infrastructure insights
Savannah's unique coastal environment and historic infrastructure present distinct challenges for storm drainage & retention construction projects. The city's high water table, frequent tropical storms, and aging utility systems dating back to the 19th century require specialized expertise that only local contractors can provide. Our team understands Savannah's specific soil composition—primarily sandy loam with clay layers—and how it affects storm drainage & retention construction installation and maintenance. We're also familiar with the city's strict historic preservation requirements, particularly in the Historic District where any utility work must be carefully coordinated with the Historic Savannah Foundation and local preservation boards.
The Savannah area's rapid growth, especially in communities like Pooler, Richmond Hill, and the Islands, has created increased demand for reliable storm drainage & retention construction solutions. Our experience with the Savannah-Chatham County Metropolitan Planning Commission's development requirements and the city's stormwater management regulations ensures your project meets all local standards. Whether you're working on a new development in the booming Pooler corridor or upgrading infrastructure in Savannah's historic neighborhoods, our local knowledge helps navigate the complex permitting process and ensures compliance with Georgia's environmental protection standards.

Storm Drainage & Retention Construction in Savannah: frequently asked questions
What is a stormwater retention system?
A stormwater retention system captures and holds rainwater runoff to prevent flooding, reduce erosion, and improve water quality before releasing it slowly into the environment. Common types include retention ponds, underground chambers like CulTec systems, and bioswales.
What are the environmental regulations for storm drainage in Georgia?
Georgia requires compliance with the Georgia Stormwater Management Manual and EPA National Pollutant Discharge Elimination System (NPDES) permits. Projects must include erosion and sediment control plans and post-construction stormwater management to protect water quality.
How do you handle storm drainage for new developments?
We design and install complete stormwater management systems including catch basins, storm pipes, retention/detention facilities, and outfall structures. Our solutions comply with local development requirements and ensure effective water management for the life of the project.
What is a CulTec underground retention system?
CulTec is an underground stormwater retention and detention system that uses high-density polyethylene (HDPE) chambers buried beneath the surface. It provides the same storage capacity as traditional ponds while maximizing usable land area for development.
