not mean complete elimination but shall require that the most substantial
efforts possible under the circumstances have been taken to reduce
the adverse effect of the action required to be minimized. With respect
to activities, the conduct of which is adverse to the preservation

the site index is highly correlated with forest yield, forest structure,
species composition, and other ecosystem functions and community characteristics.
High site index tends to occur in cool, moist environments of coves
and northeast-facing slopes; low site index in hot, dry environments
of steep convex slopes and southwest facing hillsides. Site indexes
are mapped on pages 262 to 272 of the Fox Chapel Natural Resources
Plan.

five-foot contour lines is between 33 1/3 feet and 20 feet) or
between adjacent contour lines having an interval of five feet or
less as shown on detailed site plans prepared by a registered engineer
or surveyor based on actual field topographical survey.
B.
VERY STEEP SLOPESAreas where the slope exceeds 25% between adjacent contour lines as shown on the Fox Chapel Borough Geological Hazard Maps (i.e., where the scaled horizontal distance between the five-foot contour lines is less than 20 feet) or between adjacent contour lines having an interval of five feet or less as shown on detailed site plans prepared by a registered engineer or surveyor based on actual field topographical surveys.
