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
shall be such as to eliminate any requirement for mowing, weeding
or other forms of maintenance.
All areas stabilized by vegetation and all landscaped
areas shall be properly maintained by the person or firm constructing
the road, drainage facilities and associated improvements until permanent
growth of such plantings has been firmly and effectively established.
