• Watershed Analysis Rule 2.06.5(2)(d) LS =length and percent slope factor L =length of slope and S =percent slope are combined into an LS factor The length slope factorwill vary between the approved' and 'proposed' configuration of the site. Length slope factors will be derived from the plan view shown on Exhibit 6C for the 'approved' and 'proposed' configuration (approved Exhibit 6C is in the permit, proposed Exhibit 6C is the map submitted with the PR-03 application). The comparison is broken into 'Flat' and 'Steep' slopes for Drainage Areas A, B, and C. Length of slope and percent slope are used with Figure 4, Values of Topographic Factor to determine the "LS" factor. The length of slope is considered to end where it transitions into another basin. The following tables show the interpolation of data from Figure 4. The bold data are the measured length of slope, percent slope and interpolated LS factor.
