Table 5, Classes for Degree of Pedestalling.*
I • SSF
Class Description Value
Stable Pedestals are mostly less than 0 or 3
.1 in. (2.5 mm) high and 1 or
less frequent than 2 pedestals
per 100 sq. ft.
Slight Pedestals are mostly between .1 6
to .3 in. (2.5 to 8 mm) high,
and/or have a frequency of 2
to 5 pedestals per 100 sq. ft.
Moderate Pedestals are mostly between .3 9
to .6 in. (8 to 15 mm) high,
and/or have a frequency of 5
to 7 pedestals per 100 sq. ft.
Critical Pedestals are mostly between .6 11
to 1 in. (15 to 25 mm) high,
and/or have a frequency of 7
to 10 pedestals per 100 sq. ft.
Severe Pedestals are mostly over 1 in. 14
(25 mm) high, and/or have a
frequency of over 10 pedestals
• per 100 sq. ft.
*Pedestals due to erosion are not to be confused with those caused by
frost-heaving. Examination of the roots and crowns of vegetation will
assist in this determination.
