Slope, Average. The characteristic slope over an area of land, expressed in percent as the ratio of vertical rise to horizontal distance. In any cluster development (see Section 23.04.036) or where the size of the proposed new parcels is 10 acres or greater, average slope is to be determined for the entire site and does not need to be determined for each proposed parcel. In all other cases, average slope is to be determined based on the most accurate available topographic information for each proposed new lot. One of the following methods for determining average slope is to be used:

Basic Method. Where slopes are uniform, with little variation, the basic method can be used to determine average slope. Where a line is drawn between highest and lowest points on a parcel is adequate to represent direction and extent of slope for the entire parcel, the difference in elevation between the high and low points, divided by the distance between the points, will determine the average slope.

Sectional Method. Where the parcel contains distinct sections of differing slope, the average slope of each section may be determined according to the contour measurement method in (c) below. The average slope of each section is then used in proportion of the section's area to the total area to determine the average slope of the entire parcel.

Contour Measurement Method. Where varied slope conditions or complex topography exist, the most precise measurement of average slope is the contour measurement method. The following formula shall be used to determine average slope:

S = .00229(I × L)
A

Where:

S = Average slope of parcel in percent

A = Total number of acres in the parcel (or section of parcel)

L = Length of contour lines in scaled feet

I = Vertical distance of contour interval in feet.
