The purpose of the conservancy and flood plain districts is to provide for the protection of the public health, safety and general welfare in those areas of the City which, under present conditions, are subject to periodic flooding and accompanying hazards and to conserve natural resources of benefit to the general public interest.

The objectives of the flood plain district shall be:

(a)

To prohibit occupancy or the encroachment of any structure, improvement or development that would obstruct the natural flow or floodwaters within a designated floodway on the flood plain;

(b)

To keep developments in the remainder of the flood plain above the design flood flow elevation;

(c)

To prevent economic loss caused by excessive flooding and to prevent loss of life or property;

(d)

To conserve natural topographic and scenic resources from urban development.

The flood plain of the design flood shall be subdivided into two zones for regulation purposes:

(a)

"Zone FP-1, designated floodway" means the channel of a stream and that portion of the adjoining flood plain required to reasonably provide for the construction of a project for passage of the design flood including the lands necessary for construction of project levees;

(b)

"Zone FP-2, restrictive zone" means the portion of the natural floodway between the limits of the designated floodway and the limits of the flood plain, as determined by the selected floods, where inundation may occur but where depths and velocities are generally low.

No building, structure or land shall be used, and no building or structure shall be hereafter erected, structurally altered or enlarged, except for the following purposes:

(a)
