Fill: 1.Fill, dredge spoil, and all other similar materials, if approved to be deposited or stored, deposited or stored in the flood plain shall be no more than the minimal amount necessary to conduct a conditional use. The fill, dredge spoil, and all other similar materials deposited or stored in the flood plain shall be protected from erosion by vegetative cover, mulching, riprap or other acceptable method. 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. Ks an alternative, and consistent with Subsection (d)(2) 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 whicn assures the removal of the materials from the floodw-ay 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. 4. All filling and grading activities shall be performed with only clean fill. Accessory Structures 1. Accessory structures shall 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 flcod 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 at its largest projection, and for a detached garage, the detached garage must be used solely for parking of vehicles and limited storage. All flood proofed accessory structures must meet the following additional standards: a.The structure must be adequately anchored to prevent flotation, collapse or lateral movement of the structure and shall be designed to equalize hydrostatic flood forces on exterior walls; J Distnchl htapi I/I/2004 rivUi^n -8-
