Subject: SUB200800183, Belle Vista Subdivision, Warm Blood Road, private street request
The request for a private street submitted according to Subdivision Ordinance section 14 -232 has been
reviewed. The proposed street is an upgrade to an existing driveway currently serving the parcel. The
private street would be required to meet the standard for private streets serving three to five lots (14-
412A2). A standard turnaround is proposed at the point where one driveway exits the street, and the
street may be reduced to the two -lot standard.
The proposed subdivision creates three residential lots. The projected traffic expected from three lots is 30
vehicle trips per day. The proposed private street is adequate to carry this traffic volume.
The proposed design of the private street meets the following requirements of the ordinance for streets
serving three to five lots (14- 412A2): minimum K values for vertical curves (5 and 15), 100 -foot sight
distance, 30 -foot minimum easement width (50 foot is proposed), horizontal curve minimum 40 -foot
radius, and 14 -foot minimum travelway width.
A public street to serve this subdivision would need to meet the VDOT standards for a Rural Local Road
serving less than 400 vehicle trips per day. The requirements are as follows: minimum K values for
vertical curves (7 and 17), 125 -foot sight distance, 50 -foot minimum easement width, horizontal curve
minimum 108 -foot radius, and an 18 -foot travelway width. The street, as proposed, does not meet the
public road standard for K values and travelway width.
Constructing a public street to meet these requirements would require more earthwork and more
disturbance to the existing driveway bridge than the construction of a private street.
Engineering has no objection to the private street waiver request.
