In the City of Suffolk the Chesapeake Bay Preservation Area Overlay District includes standards that are applied to development activities within the CBPA. These standards ensure that water quality is protected by reducing nonpoint source pollution through the treatment of stormwater runoff. In addition, the preservation of existing trees and natural vegetation is a key component of protecting water quality within Suffolk’s watershed. The Chesapeake Bay Preservation Areas are made up of three separate components: Resource Protection Areas (RPAs), Resource Management Areas (RMAs) and Intensely Developed Areas (IDAs).
