§ 26-56-030. Development standards for floodways.
The decision-making body shall be guided by the following standards in administering the FW district:
(a)
The placement and type of materials used in bank stabilization shall be complementary to surrounding development and natural conditions and shall not be depreciative of surrounding property values.
(b)
Where, in the opinion of the planning director or other decision-making body, topographic data, engineering studies or other studies are needed to determine the effects of bank erosion on a proposed structure or the effect of the structure, including bank stabilization activities, on the floodway and natural vegetation, the applicant may be required to submit such data.
(c)
Within the Laguna de Santa Rosa, a "zero net fill" policy shall be enforced whereby no fill shall be permitted to be placed in the Laguna unless an engineering analysis demonstrates that no reduction in flood storage capacity would result from the placement of fill. For purposes of this article, the "Laguna" shall be defined as the Laguna de Santa Rosa and tributaries thereto which are within designated floodways on the most recent FEMA maps.
(d)
Temporary structures such as floating docks and moorage facilities may require issuance of a use permit.
(e)
Except as specifically allowed in this article, no building or structure shall be constructed, erected, moved, converted, altered or enlarged in the floodway, nor shall any other condition be allowed which would tend to cause significant stream channel alteration or adversely affect the carrying or storage capacity of a floodway, or otherwise constitute a threat to life and property. Ordinary maintenance and repair of existing nonconforming structures shall be permitted subject to the provisions of Article 94.
