at the two-foot depth, place geotextile fabric in the bottom prior
to backfilling with 2A or 3A modified crushed stone.
(4)
The applicant shall place and compact a minimum six-inch depth
of 2A modified crushed stone.

(4)
The applicant shall place and compact a minimum six-inch depth
of 2A modified crushed stone.

Engineer, and testing shall be performed at the expense of the applicant.
