A.
General. Except as otherwise specified herein, all
areas disturbed by construction of roads, drainage facilities and
associated improvements that are not paved or occupied by structures
shall be properly graded to smooth uniform slopes, covered with topsoil
to a minimum depth, after settlement, of six inches and limed, fertilized,
seeded and mulched.
B.
Materials and methods. All materials and construction
methods shall conform to the requirements of the State Standard Specifications
for Topsoil; Fertilizing, Seeding and Mulching; and Liming.
Center islands of turnarounds, and median strips
where permitted, shall be planted with low-growing shrubs and plants
that will permit full vision at all points, except that a tree or
trees of an approved species may be planted anywhere within five feet
of the center of the island of a turnaround. An ornamental boulder
or grouping of rocks or boulders may also be placed anywhere within
five feet of the center of the island of a turnaround. All plantings
