In certain situations, the
use of alleys may be a desirable alternative to the more traditional type of residential
development. Alleys may be permitted in residential planned developments, cluster
development, or similar residential subdivisions where average lot widths are less than
seventy feet (70'), however, the following conditions shall apply:
(a) Frontage on an alley shall not be construed to satisfy any
lot frontage requirements.
(b) Alleys shall be
maintained and perpetuated by a duly constituted property owners'
association and notations to this effect, including a note that such
alleys will not be eligible for acceptance and maintenance by the
Virginia Department of Transportation, shall be clearly indicated on
the face of the record plat.
(c) Alleys shall have a minimum right-of-way width of sixteen
feet (16'), a minimum pavement width of twelve feet (12') and a maximum length of five
hundred feet (500').
(d) Alleys shall be designed to minimize or eliminate the
potential for through traffic.
(e) Alleys shall intersect only access or subcollector streets.
(f) If curb and gutter is used, it shall be of a roll-top type
design.
(g) All structures, including garages and fences shall be set
back a minimum of ten feet (10') from the edge of the alley right-of-way. Alleys shall not
be considered streets or roads for the purpose of front yard setback requirements.
(h) Where alleys are
proposed to terminate in a cul-de-sac, either a circular or a "T" or
“Branch” turnaround shall be provided with a minimum outside turning
radius of thirty feet (30').
