§42-106.
Private Road Standard Reductions
A.
Right-of-way Width Reduction. Right-of-way width requirements may be reduced to 30 feet in width
where no more than five (5) lots are proposed and it is unlikely (due to design, topographic conditions or
existing development) that any road contained therein would be extended to serve more than five (5) lots.
Right-of-way width reductions are also permitted where the development is a dwelling, multifamily, five (5)
or more units, provided these modifications are approved by the reviewing agency with consideration to
sound engineering, public safety concerns and community character.
B.
Travelway Width Reduction. Travelway width requirements for private subdivision limited local roads in
special subdivisions may be reduced to nine (9) feet where an existing road with a travelway width of at
least nine (9) feet occurs. The Subdivision Administrator will permit the reduction only upon inspection for
road stability and provided that all other private subdivision limited local road standards are met. Existing
roads shall be improved to meet the private subdivision limited local road standards before a final plat can
be approved.
C.
Centerline Curve Radius Reductions. Centerline curve radius reductions may be reduced to:
(1)
80 feet where the existing cross slope on private subdivision collector roads is 15 percent or
greater, or
(2)
60 feet where the existing cross slope on private subdivision limited local residential subdivision
roads or private subdivision local residential subdivision roads is 15 percent or greater.
Centerline curve radius reductions are also permitted where the development is a dwelling, multifamily, five
(5) or more units, provided these modifications are approved by the reviewing agency with consideration to
sound engineering, public safety concerns and community character.
D.
Shoulder Width Reduction. Shoulder width shall be reduced for:
(1)
Private subdivision local roads and private subdivision collector roads to a minimum of two (2)
feet in cases where the existing cross slope is 20 percent or greater; and 
(2)
Private subdivision collector roads to a minimum of four (4) feet in cases where the existing cross
slope is greater than ten (10) but less than 20 percent or greater.
E.
Cut and Fill Slopes. Cut and fill slopes shall be reduced to 1:1 where the existing cross slope is 20 percent
or greater.
