Drainage Courses Clause Samples

Drainage Courses. The alignment and capacity of major drainage courses (i.e. Willow Creek, canal systems, FEMA Firm map courses, and natural regional drainage courses) shall not be modified by grading activities. Any proposed modifications to a drainage course must be reviewed and approved by the City Engineer, but in any case, modifications will not reduce the capacity and will not create adverse effects upstream or downstream of the original drainage course. Installation of culverts shall meet the requirements of Section 4.
