a controlled perimeter, the standoff distances and explosive weight associated with
parking and roadways in Table B-1 apply. If there is no controlled perimeter, assume
that the larger explosive weights upon which the controlled perimeter standoff distances
are based (explosive weight I from Table B-1) can access parking and roadways near
buildings. Therefore, where there is no controlled perimeter, use standoff distances
from parking and roadways according to the distances and the explosive weight
associated with controlled perimeters in Table B-1. Measure the standoff distance from
the closest edge of parking areas and roadways to the closest point on the building
exterior or inhabited portion of the building. In addition, the following apply:

(1) Even with analysis, standoff distances less than those in this column are not allowed for new buildings, but are
allowed for existing buildings if constructed/retrofitted to provide the required level of protection at the reduced standoff
distance.
(2) See UFC 4-010-02, for the specific explosive weights (kg/pounds of TNT) associated with designations I and II.
