For any portion of land containing slopes above seventy-five percent (75%), the maximum density is determined as .25 of the density determined by dividing the gross area of the tract of land above the seventy-five percent (75%) slope line by the minimum lot size specified in the underlying zoning district(s). e. For any portion of land containing a floodway established by the Yavapai County Drainage Criteria Method, the maximum density is determined as .50 of the density determined by dividing the gross area of the tract of land within the floodway by the minimum lot size specified in the underlying zoning district(s). f. The maximum density established by subsections a. through e. above may be increased as provided in Section 441.D. through the inclusion of conservation features or design elements identified in Section 441.D. g. Slope Category Determination shall conform with the methodology of Section 560.B. and C. of the Yavapai County Subdivision Regulations. 4. Minimum Lot Size: The minimum lot area, minimum lot width and minimum lot depth established by the underlying zoning district(s) shall not be applicable. Buildable areas are encouraged to be varied and shall be approved by the County based on the suitability of the proposed lot sizes with surrounding land uses to ensure compatibility. 5. Development Standards: The minimum building setbacks and maximum percentage of lot coverage established by the underlying zoning district(s) shall not be applicable. All buildings shall not exceed the maximum building height established by the underlying zoning district. The minimum building setbacks and maximum percentage of lot coverage shall be submitted and approved by the County as part of the Open Space and Sustainable Development Option review process. 6. Natural Watercourses and Cultural Resources: a. Construction within floodplains shall meet County subdivision requirements and be minimized to the greatest extent. To incentivize the protection of natural watercourses, density transferred outside the floodplain area shall be allowed at a value equal to 1.25 times the underlying density of the area maintained in natural state. b. Historic buildings and archeological sites listed on the National Register, at the State Historic Preservation Office or in local studies shall be preserved and protected. A Level 1 survey shall be completed to identify previously unmapped historic buildings and archeological sites. Historic buildings and archeological sites identified by the Level 1 survey shall be preserved and protected. 7. Limitations on Cuts and Fills a. Any driveway cut greater than eight feet (8’) in depth shall not have a length greater than one hundred feet (100’); and the maximum height of any cut or fill used to establish a driveway shall not exceed fifteen feet (15’).
