The purpose of the Charles County Stormwater Management Ordinance ("Ordinance") is to protect, maintain, and enhance the public health, safety, and general welfare by establishing minimum requirements and procedures to control the adverse impacts associated with increased stormwater runoff.
The primary goals of the Charles County Stormwater Management Program are to maintain, after development, as nearly as possible, the predevelopment runoff characteristics, and to reduce stream channel erosion, pollution, siltation and sedimentation, and local flooding by implementing environmental site design (ESD) to the maximum extent practicable (MEP) and, for water quality purposes only, when necessary, using appropriate structural best management practices (BMPs).
The provisions of this chapter are adopted pursuant to the authority of the Environment Article, Title 4, Subtitle 2, of the Annotated Code of Maryland, 2009 Replacement Volume and Article 25, § 3, of the Annotated Code of Maryland and apply to all new development or redevelopment of land, including, but not limited to, residential, commercial, industrial, or institutional use. The application of this chapter and the provisions expressed herein shall be the minimum stormwater management requirements and shall not be deemed a limitation or repeal of any other powers granted by state law. The Department of Planning and Growth Management shall be responsible for the coordination and enforcement of the provisions of this chapter.
