Storm drainage run-off from the subdivision shall be collected and conveyed by an approved storm drain system. The storm drain system shall be designed for ultimate development of the watershed. The storm drain system shall provide for the protection of abutting and off-site properties that would be adversely affected by any increase in run-off attributed to the development; off-site storm drain improvements may be required to satisfy this requirement. Storm drain improvements shall be designed so as not to create erosion and sediment control problems. (Ord. 5793-NS § 2 (part), 1987)
