The purpose of the designated floodway (F-l) district is to maximize the use of land located within the designated floodway in a manner consistent with the need to protect life and property, and to minimize environmental damage to riparian and aquatic habitats. This district is consistent with all general plan land use designations. Located within areas of special flood hazard established in Section 17.02.030(D) are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters, debris, potential projectiles and erosion, the following provisions apply.

(Ord. 97-4 § 23, 1997: prior code § 5.02.100 (A))

The following uses are permitted outright in the F-1 district, unless a use permit is required by Section 17.22.030.E:

B.

Crop farming, truck gardening, orchards, viticulture, livestock grazing and other similar agricultural uses conducted in a manner which will not increase flood levels within the community during the occurrence of a base flood discharge.

C.

Public roads, bridges and diversion drains, and public utility transmission towers, poles, lines and underground pipelines, when constructed and installed so that the flood levels will not increase within the community during the occurrence of the base flood discharge.

F.

Fish and wildlife protection or enhancement projects conducted or approved by a federal or state agency, the county or the county water agency, provided that there is no rise in the base flood elevation during the occurrence of the base flood discharge.
