This article is established to promote the public health, safety and general welfare of the community by regulating and restricting the development of areas along or in drainageways, channels, streams and creeks. The regulations that follow are intended to protect and to preserve the location, character and extent of such drainageways, channels, streams and creeks, and to protect persons and property from the hazards of development in areas that may be subject to inundation.
A. 
No building or structure shall be erected within any area herein described as a "drainagecourse." For the purpose of this and the following subsections, a drainagecourse shall include any area, such as drainageways, channels, streams and creeks, designated as such on the Zoning Map and shall further include any area designed or intended for use for drainage purposes as shown in a recorded subdivision.
B. 
No permit shall be issued for filling of land within a drainagecourse, or on any lands within 100 feet, or more than 100 feet when so designated on the Zoning Map, of the center line of such drainagecourse, except upon approval, in writing, by the City Engineer that such filling will not obstruct the flow of water or otherwise reduce the water-carrying capacity of such drainagecourse, or impair the design and character of such drainagecourse.
C. 
No permit shall be issued for excavating of land within a drainagecourse, or on any lands within 100 feet, or more than 100 feet when so designated on the Zoning Map, of the center line of such drainagecourse, except upon approval, in writing, by the City Engineer that such excavating will not divert water from the established channel, will not cause flooding of lands outside such drainagecourse, will not cause any erosion, and will not otherwise impair the design and character of such drainagecourse.
D. 
No relocation, enclosure or bridging of a drainagecourse shall be permitted except upon approval, in writing, by the City Engineer that the location, character and extent of such relocation, enclosure or bridging of the drainagecourse shall be in the public interest.
