Section 7.100 - Design Standards for Streets
Detailed construction standards and specifications for state standard streets are contained in the Land Development Standards Manual. For Town Streets, the standards of Article 5 of the Huntersville Zoning Ordinance shall control.
1. On proposed streets, right-of-way must be of sufficient width to accommodate the required cross section. However, in no case will the dedicated and/or reserved right-of-way be proposed to be less than the standards below. The Town Board, on the advice of the Town Engineer or their designee, may certify that special circumstances exist which make the dedication and/or reservation of the full right-of-way unnecessary or impractical.
Minimum R.O.W by Street Classification
|Freeway or Expressway (Class I)||250-350|
|Limited Access Arterial (Class II)||200|
|Commercial Arterial (Class III-C)||150|
|Major Arterial (Class III)||100|
|Minor Arterial (Class IV)||70|
|Collector (Class V)||60|
|Town Streets||Varies according to the standards of Article 5 of the Huntersville Zoning Ordinance|
These standards represent the normally required rights-of-way for state standard streets. Additional right-of-way may be necessary in the area of interchanges, intersections, cut/fill areas, or areas where horizontal or vertical alignments must be improved and will be determined on a case by case basis. When a subdivider elects to establish a roadway divided with a center strip or median, the right-of-way width must be at least the proposed width of the center strip or median plus 62 feet.
2. Along existing streets, neither right-of-way dedication nor reservation is required unless
(a) an existing street has a right-of-way less than 60 feet wide and will provide access to the subdivision, in which case a right-of-way up to 30 feet on each side of the centerline may be required to be dedicated; or
(b) an existing street will provide access to the subdivision and volume of traffic projected to be generated by the subdivision necessitates intersection and/or other improvement(s), in which case dedication of right-of-way sufficient for the subdivision developer to make intersection and/or other improvements to serve said subdivision may be required.
The Town Board, after consulting applicable plans and programs and after consulting with appropriate county, state, and/or federal officials, is responsible for classifying streets or segments thereof within the zoning and subdivision jurisdiction of the Town of Huntersville.
7.120 FREEWAYS / EXPRESSWAYS (NEW)
Whenever a tract of land to be subdivided includes any part of the right-of-way of a planned freeway or extension of a freeway, as shown on the adopted Thoroughfare Plan, and whenever such a right-of-way has been further defined by acceptable locational procedures sufficient to identify properties to be affected, the right-of-way for the freeway must be reserved, platted in the location and to the width specified in the plan, and remain undeveloped pending future acquisition by the state or other governmental unit. The subdivider is responsible for the reservation of the right-of-way in accordance with the provisions of Section 8.110, Improvement Responsibility. The entire right-of-way must be shown as such on the final plat. All measurements involving minimum lot standards under this ordinance and under the zoning ordinance will be made at the edge of the full right-of-way. Right-of-way that is dedicated by the subdivider will count toward the transfer of development rights in accordance with Section 7.135.
7.130 ARTERIAL STREET RIGHT-OF-WAY (NEW STREETS)
Whenever a tract of land to be subdivided includes any part of a planned arterial or extension of an existing arterial street shown on the adopted Thoroughfare Plan, and whenever a right-of-way for such a street has been further defined by acceptable locational procedures sufficient to identify properties to be affected, a right-of-way for the arterial street must be platted in the location and to the width specified in the plan. The subdivider is responsible for the dedication and/or reservation of the right-of-way in accordance with the provisions of Section 8.110, Improvement Responsibility. The entire right-of-way (that which has been reserved and that which has been dedicated) must be shown as such on the final plat. All measurements involving minimum lot standards under this ordinance and under the zoning ordinance will be made at the edge of the full right-of-way. Arterial Street right-of-way that is dedicated by the subdivider will count toward the transfer of development rights in accordance with Section 7.135.
7.135 TRANSFER OF DEVELOPMENT RIGHTS - R/W DEDICATION
All of the area dedicated by the developer as right-of-way for any public street may be used in the computation of development rights, but may not be used for the computation of lot area or open space, or fulfill storm water detention, or any other mandatory requirement. On-street parking which is planned, provided for, and approved will, however, be applied to the mandatory parking requirement. A developer may choose to dedicate the full right-of-way and thereby use the entire dedicated area for the density calculation.
Cul-de-sacs (streets designed to be permanently closed at one end), may not be longer than 350 feet and must be terminated by a vehicular turnaround design as accepted by the Town Engineering Department; provided, however, that this requirement may be waived where topographical or other unusual conditions exist.
7.170 STREET OFF-SETS
Where there is an offset in the alignment of a street across an intersection, the offset of the centerlines should not be less than 300 feet for arterials. Offsets for other street types will be determined based upon projected traffic volumes and the applicability of traffic calming measures.
7.180 BLOCK LENGTHS AND WIDTHS
Block lengths may generally not exceed 500 feet, except as hereinafter provided. Where a longer block will reduce the number of railroad grade crossings, major stream crossings, or where longer blocks will result in an arrangement of lots and public space more consistent with Articles 5 and 7 of the Huntersville Zoning Ordinance, the Town Board may authorize greater block lengths.
