The Indiana Stormwater Control Ordinance is a set of regulations designed to manage and control stormwater runoff in the state of Indiana. These ordinances aim to prevent water pollution, flooding, and erosion caused by uncontrolled stormwater runoff. One of the key components of the Indiana Stormwater Control Ordinance is the requirement for stormwater management plans and the implementation of the best management practices (BMPs). These plans must be created and followed by developers, contractors, and property owners when undertaking construction projects or land development activities that disturb more than one acre of land. The ordinances outline specific guidelines and standards for stormwater management, including the use of various stormwater control measures. These measures may include the installation of stormwater detention basins, retention ponds, bioswales, permeable pavements, and green infrastructure. By implementing these measures, the ordinances aim to reduce the volume and velocity of stormwater runoff, promote infiltration, and improve water quality. It is important to note that different types of Stormwater Control Ordinances may exist in Indiana, which can vary between counties or municipalities. Examples of such ordinances include the Indianapolis Stormwater Design Manual and the Monroe County Stormwater Management Ordinance. These ordinances may have specific requirements tailored to the unique characteristics and needs of their respective areas. In conclusion, the Indiana Stormwater Control Ordinance is a comprehensive set of regulations that aim to manage and control stormwater runoff in Indiana. These ordinances require the implementation of stormwater management plans and the use of appropriate stormwater control measures to prevent water pollution, flooding, and erosion. The existence of different types of Stormwater Control Ordinances in Indiana demonstrates the recognition of the need for localized approaches to better protect the environment and community health.
