Description  
    Abstract
    Polygon data layer identifying areas where the percent slope is
    greater than 30%
     
     
    Purpose
    Used for identification of steep slopes
     
     
Supplemental_Information
    Procedures_Used
    A percent slope model was derived from Metro 10m contours using topogrid
    to create dem, and slope to extract percent slope.  Values were sliced
    into equal intervals ranging from 0 to 99. into 10 groups.  All slope
    classes greater then 30 were then converted to polygon coverage.
