Stormwater Management

Construction Sites

The Delaware Sediment and Stormwater Regulations require that Sediment and Stormwater (S&S) be managed at construction sites to prevent erosion and runoff of sediment from the construction site.

DelDOT has been delegated by DNREC to administer its own Sediment and Storm Water Management Program. The program requires all construction activities and development that disturbs over 5,000 square feet to develop a stormwater management and sediment control plan to be submitted for review and approval. The submission requires a summary of field conditions, hydrologic and hydraulic computations, a plan checklist and details for sediment control and storm water management practices. During construction DelDOT inspects the site regularly for compliance with the approved plans.
