A. Slope: Slope shall be determined on an individual development parcel basis as an average percent natural slope for purposes of density limitations.
B. Procedure: The location of the natural twenty percent (20%) to twenty nine percent (29%) and thirty percent (30%) or greater slopes shall be determined based upon the following procedure:
1. Preparation Of Contour Maps: Current contour maps shall be prepared and certified by a licensed professional engineer or surveyor showing contours at intervals no greater than five feet (5') drawn at a scale of not less than one inch equals one hundred feet (1" = 100') scale.
2. Verification: Field surveys may be required of the applicant by the county public works director to verify the accuracy of the contour lines shown on the contour map. All development on slopes in excess of twenty percent (20%) shall identify profile lines which shall be used for performing the field survey. Profile lines shall be perpendicular to contour lines and in no case occur at intervals greater than one hundred fifty feet (150') apart or seventy five feet (75') from a property line.
