§ 9.3.2. Natural Channels
Runoff that results from upstream development and is discharged to an unimproved waterway can cause flood damage to properties adjacent to the waterway. Natural undeveloped waterways do not receive regular maintenance. Design of natural waterways shall take into consideration fluvial geomorphologic principals and practices and other erosion control measures. Design engineers and development review officials shall work to resolve potential downstream impact issues.
A drivable access way shall be provided in floodplain easements for the length of the easement when regular maintenance of the floodplain is required.
