The Delaware Sediment and Stormwater (S&S) regulations require that sediment control and stormwater management practices be implemented and managed to prevent erosion and sediment runoff from construction sites.
DNREC delegated DelDOT to administer its own Sediment and Stormwater Management program. This program requires all construction activities and development disturbing over 5,000 square feet to submit a Stormwater Management and Sediment Control plan. The Plan is required to include a summary of field conditions, hydrologic and hydraulic computations, a plan checklist, and details for sediment control and storm water management practices. DelDOT regularly inspects construction sites for compliance with the DNREC-approved plans.
