The minor system consists of structures including, but not necessarily limited to, detention facilities and stormwater treatment facilities, and roadway curb and gutter, open channels, swales and enclosed conveyance systems, all as defined in this chapter, which transport storm runoff to the major system (regulatory floodplain). Minor system facilities are those designed to accommodate runoff resulting from a storm with a given design frequency. (Ord. 22-52 § 3, 2022; Ord. 09-25 § 2, 2009.)
