These Regulations apply to all hillside areas. A hillside area as referred to herein is defined as one with an average slope of more than fifteen percent (15%). These areas may be found in the three-mile area outside the corporation limits. The subdivider shall submit sufficient detailed information as to geologic conditions, soil types and underground water level in order that a determination can be made by the City or County Engineer, as the case may be, as to the safety of development of the particular location.
(1984 Code Sec. 151.100)
The average slope and soil stability for any hillside development shall be determined by the City Planning Commission during the time of preliminary subdivision design. Determination shall be on an area-by-area basis with each lot sized according to the average topographic change falling within each area.
(1984 Code Sec. 151.101)
The minimum lot requirements (for minimum lot size requirements see chart below) shall be used to determine the minimum lot area for a single-family home. The average percent of slope is determined by the City Planning Commission. The lot area in thousands of square feet shall then be determined by charting the average natural ground slope and the minimum lot area. Rounding shall be made to the nearest five-foot frontage interval. Deviations from these requirements may be allowed subject to determination by the Commission where exceptional circumstances warrant.
MINIMUM LOT SIZE REQUIREMENTS
BASED ON SLOPE
 |
EXAMPLE: As indicated above, the minimum lot size for a single-family house on a lot with an average slope of 28 percent is 26,000 sq. ft. The minimum lot width is 130 feet. The resulting lot depth is 200 feet.
26,500 = 200 130 |
