driveways and drive aisles, are not entirely screened visually by
an intervening building or structure from any abutting right-of-
way, there shall be provided landscaping designed to buffer direct
views of cars and hard surface areas. The goal of this section is
to break up expanses of hard surface areas, help to visually define
boulevards and soften direct views of parking areas.

landscape area no more than two and one-half (22)
feet, as long as a concrete curb is provided to
ensure no greater overhang or penetration of the
landscaped area.
7) All landscaped areas shall be protected by concrete
curbing.
Section 20-1182. Foundation and Aesthetic Plantings.
(a) Landscaping plans shall provide for an appropriate mix of
plantings around the exterior footprint of all buildings. The
