Post-Construction Stormwater Management

Post-construction storm water management in areas undergoing new development or redevelopment is necessary because runoff from these areas has been shown to significantly effect receiving waterbodies. Many studies indicate that prior planning and design for the minimization of pollutants in post-construction storm water discharges is the most cost-effective approach to storm water quality management.

The City of Mandan adopted an ordinance in August, 2006 which requires a stormwater plan to be submitted to the city for approval before qualifying building permits or plats may be approved.  This ordinance includes requirements for runoff protection for post-construction as well as during construction.
