STREAM CORRIDOR PROTECTION ZONES
The City’s Stormwater Drainage Manual requires developers to establish Stream Corridor Protection Zones (SCPZ) when new development or redevelopment is proposed on property where streams are located. SCPZs consist of the stream and the riparian area along it and are protected through either deed and plat restrictions, easements or by City ownership. The purpose of the SCPZ is to allow the natural, lateral movement of open water courses, provide sufficient area for flood conveyance, protect water quality and prevent structures from being impacted by natural streambank erosion.
