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.

The County implements many procedures during site planning to minimize short and long term impacts to water quality including:

  • A County approved S & S plan and a Notice of Intent (NOI) must be on file with Delaware’s Department of Natural resources adn Environmental Control prior to record plan approval.
  • The design engineer and site contractor must meet to discuss the S& S plan and make sure the phasing works and the plan can be built as designed.
  • A pre-construction meeting is required which assembles all parties involved in site construction. The developer/owner, site contractor, and certified construction reviewer (CCR) are required to certify, by signature, that they understand and will discharge their responsibilities.
  • A perimeter control inspection to ensure all appropriate perimeter controls must be in place to prevent sediment from leaving the site.
  • Nominal weekly inspections are conducted and an enforcement process is in place to compel compliance with the regulations, policies and procedures.

The State of Delaware Division of Soil and Water conducts training and education sessions for construction site operators. In addition, the County holds training session for CCRs and Site Operators to assist them with the process and procedures for S&S program compliance. The County manages a CCR Program to help the County with inspections to ensure construction sites remain in compliance with the approved S&S plan and S&S Regulations.
