G. Residential Frontage
1. Residential lots shall not front onto a Type A, B, or C thoroughfare or a residential collector
unless parallel access roads are provided. The minimum distance between adjacent curbs of
the thoroughfare and the access road shall be twenty feet (20’). Access road ROW shall be in
addition to the thoroughfare ROW and access roads shall not connect to the adjacent
thoroughfare.
2. Residential lots shall not front onto a Type D, E, F, or G thoroughfare within one hundred
feet (100’) of the ROW line of the nearest Type A or B thoroughfare.
3. Residential lots shall not front onto any portion of a Type D, E, F, or G thoroughfare that is
part of a residential collector, which is a street that connects to a Type A or B thoroughfare
and extends into a neighborhood for more than six hundred feet (600’) without changing
direction (see Section 2.02.I.5).
4. Residential lots shall not front onto a roundabout. Residential lots adjacent to roundabouts
shall be oriented so that their houses do not face the roundabout and their driveways do not
intersect with the roundabout or along any section of street with a splitter island.
H. Partial Streets
1. Longitudinal partial dedications of Type A and B thoroughfares shall be permitted when only
one side of a future thoroughfare is being developed. In such a case, one-half of the total
right-of-way shall be dedicated and a minimum of twenty four feet (24’) of pavement, faceto-face,
shall be constructed.
2. Longitudinal partial dedications of Type C, D, E, F, or G thoroughfares shall be prohibited,
except when essential to the reasonable development of a property in conforming with the
requirements of the Subdivision Ordinance, and where the Planning & Zoning Commission
finds that it will be practical to require the dedication of the other portion of the street when
the adjoining property is developed. Whenever a partial street exists along a common
property line, the other portion of the street shall be dedicated when the adjoining property is
subdivided or developed. Where a partial street is being dedicated along a common property
line and the ultimate planned ROW width is sixty feet (60’), the first ROW dedication will be
thirty-five feet (35’).
a. The developer shall construct a minimum of twenty four feet (24’) of pavement, face-toface,
for all Type C or D thoroughfares that are partial streets at the time of development.
b. The developer shall construct the full width of pavement face-to-face for all Type E, F, or
G thoroughfares that are partial street dedications at the time of development.
I. Street Lengths
1. Type A, B, and C thoroughfares have no street length restrictions. Residential streets (Type
D, E, F, and G thoroughfares in a single-family, duplex, or townhome neighborhood) shall
have street length restrictions to discourage speeding and cut-through traffic.
2. A residential street that intersects with a Type A or Type B thoroughfare and has residential
lots fronting any portion of the street shall not exceed a maximum length of six hundred feet
