"Maintenance" means activities conducted on currently serviceable structures, facilities and equipment that involve no expansion or use beyond that previously existing and result in no significant adverse hydrologic impact. It includes those usual activities taken to prevent a decline, lapse or cessation in the use of structures and systems. Those usual activities may include replacement of dysfunctional facilities, including cases where any permit requires replacing an existing structure with a different type structure, as long as the functioning characteristics of the original structure are not changed.

This definition applies to "Drainage" regulations in chapter 30.63A SCC and "Land disturbing activity" regulations in chapter 30.63B SCC.
