f S~bd. 4 Standards for Floodway Conditional Uses: All Uses. No structure (temporary or permanent), fill (including fill for roads and levees), deposit, obstruction, storage of materials or equipment, or other uses may be allowed as a Conditional Use that will cause any increase in the stage of the 100-year or regional flood or cause an increase in flood damages in the reach or reaches affected. All floodway Conditional Uses shall be subject to the procedures and standards contained in §9.22.10 Subd. 4 of this ordinance. The Conditional Use shall be permissible in the underlying zoning district. Fill, dredge spoil and all other similar materials deposited or stored in the flood plain shall be protected from erosion by vegetative cover, mulching, rip-rap or other acceptable method. 2. Dredge spoil sites and sand and gravel operations shall not be allowed in the floodway unless a long-term site development plan is submitted which includes an erosion/sedimentation prevention element to the plan. 3. As an alternative, and consistent with Subsection d2 immediately above, dredge spoil disposal and sand and gravel operations may allow temporary, on-site storage of fill or other materials which would have caused an increase to the stage of the 100-year or regional flood but only after the Governing Body has received an appropriate plan which assures the removal of the materials from the floodway based upon the flood warning time available. The Conditional Use Permit must be title registered with the property in the Office of the County Recorder. Accessory Structures: 1. Accessory structures shah not be designed for human habitation. 2. Accessory structures, if permitted, shall be constructed and placed on the building site so as to offer the minimum obstruction to the flow of flood waters. (a) Whenever possible, structures shall be constructed with the longitudinal axis parallel to the direction of flood flow, and, (b) So far as practicable, structures shall be placed approximately on the same flood flow lines as those of adjoining structures. (3) Accessory structures shall be elevated on fill or structurally dry flood proofed in accordance with the FP-1 or FP-2 flood proofing classifications in the State Building Code. As an alternative, an accessory structure may be flood proofed to the FP-3 or FP-4 flood proofing classification in the State Building Code provided the accessory structure constitutes a minimal investment, does not exceed 500 square feet in size, and for a detached garage, the detached garage must be used solely for parking of vehicles and limited storage.
