Article 7: Subdivisions Section 7.8: Access and Roadways (4) Fill Material (a) Where filling is necessary to raise the roadbed, cross watercourses or fill stump holes, it shall be done with suitable material that is free of roots or other organic matter. (b) The fill should be firmly compacted to reduce settlement that will cause ruts or holes in the finished road. (5) Traffic Flow (a) Private Roads shall provide for two-way traffic in order to prevent conflict of vehicles meeting head-on. (b) Two-way traffic for Class B roads can be accomplished by widening the travelway at prescribed locations to at least 16 feet to allow vehicles to pass or to pull over and stop while another vehicle passes. (c) Plans showing road and right-of-way location, ditches and culverts, extent of clearing, and existing and finish contour lines shall be approved by the Erosion Control Officer. (6) Medians (a) Medians may be permitted between travel lanes when it is demonstrated that such design is desirable for the preservation of natural resources, or that excessive cut and fill would be required to construct a roadway to the standard width. (b) Medians may be permitted only in accordance with the following: (i) Each lane shall contain a minimum of 14 feet of vertical and horizontal clearance. (ii) Each lane shall contain a minimum travelway of eight feet, or 1/2 of the required width for the applicable road class, whichever is greater. (iii) No lots shall access directly onto any divided portion of the road unless there is adequate cross-access provided through the median, or some other acceptable means of access and turnaround for emergency vehicles. (iv) Both lanes shall be contained within a single easement. (v) A standard travelway of required width for the road class shall be constructed where the private road intersects with another private or public road. (vi) Signs indicating "One Way" and/or a split roadway shall be provided where the lanes diverge. (7) Grade (a) The grade of the road should not exceed 12% because of the difficulty of operating vehicles on such a steep road and the high potential for erosion of the travelway and ditches. (b) Where possible, the road should be constructed along the contour of the land to avoid steep grades. (c) In exceptional circumstances a variance may be granted for a grade greater than 12%, as may be approved by the Board of Adjustment prior to construction (see Section 2.10 for variance procedures). Circumstances where a variance will be considered are: (i) There is no other reasonable access or location of the road, Orange County, North Carolina – Unified Development Ordinance Page 7-20 113
