4In developments
having an access road that has no frontage lots, the developer may
reduce the pavement width on this access road to 24 feet, in recognition
that there will be no intersecting driveways and no demand for curbside
parking. The intent is to reduce the cost of access roads in order
to encourage developments in rural settings to locate the homes farther
from the major road system. Where this design is used, the narrower
road shall be a consistent width from its beginning up to the first
residence, after which the applicable wider width shall be required
throughout the development.
