The Riparian Areas Protection Regulation (RAPR) is Provincial legislation that requires local governments to protect riparian areas during residential, commercial, and industrial developments in order to maintain the features, functions and conditions that support fish habitat. A RAPR Assessment may be required when considering development near watercourses, ditches, or wetlands.
