10-12-7: PROTECTION AND MAINTENANCE OF BLUFF AND RAVINE PROPERTY:
A.   Filling And Dumping Prohibited: No garbage, construction debris, or landscaping materials shall be dumped or filled in any bluff or ravine protection area.
B.   Drainage: Measures shall be required to control stormwater runoff from structures and other improved surfaces on bluff/ravine properties. Wherever feasible, such runoff shall be collected and carried to municipal storm drainage facilities located away from ravines and bluffs. If discharge directly into municipal storm drainage facilities is not feasible, drainage shall be collected and discharged directly into the base of the ravine or bluff channel via continuous, nonperforated drain lines designed to collect stormwater runoff prior to the runoff reaching the ravine or bluff area. Such drainage lines shall be buried on the slopes of the ravine or bluff, and required excavations shall be located to minimize damage to trees and the slope of the ravine or bluff. In no event shall the point source discharge of water be allowed on or near any side of any ravine or bluff. A complete site drainage plan shall be required as part of the site plan submittal required pursuant to subsection 10-12-6A of this chapter.
C.   Vegetation: Native vegetation shall be maintained to the greatest extent possible within all bluff and ravine protection areas. Section 10-13-1 of this title, illustration 16, provides a nonexclusive list of native vegetation that bluff/ravine property owners are encouraged to utilize within all bluff and ravine protection areas.
