The City Manager, shall determine which of the City's storm drainage assets will be transferred to the Utility. Until such transfer, the Utility shall operate, maintain, and improve all existing City storm drainage facilities used for the conveyance of storm waters, through, under or over lands or watercourses, beginning at a point where the storm waters first enter the storm sewer system of the City and ending in each instance at a point where the storm waters exit from the system. Storm water facilities do not include government-owned streets or those storm sewer facilities operated and maintained by, or for, the Utility, the county, or the State of Utah.
