If the areas of proposed disturbance within each of
the three categories of steep slope are individually less than the
minimum areas defined above, then the area of all contiguous steeply
sloped areas proposed for disturbance shall be merged as specified
herein. A steep slope area shall be regulated pursuant to the provisions
of this chapter if the total of all such steeply sloped areas proposed
for disturbance, as adjusted according to the weighting factors identified
below, exceeds a sum of 3/10 of an acre or 13,068 square feet.
Moderately steep slope area X 1.0 + Very steep
slope area X 1.5 + Extremely steep slope area X 3.0 = Total weighted
area
