(A) Compliance with official plans. When a tract to be subdivided embraces any part of a major thoroughfare, parkway or boulevard designated on official maps and plans, the part of the proposed public right-of-way shall be platted and dedicated by the subdivider in the location and at the width specified.
(B) Sidewalks. Street yard, buffer yard and sidewalks shall be installed according to Chapter 157, except any new subdivision street located within two blocks of a school (district access) shall be required to have sidewalks on both sides of the street, regardless of lot size and zoning classification.
(C) Streets. The following shall be considered the minimum standard of design for new streets within proposed subdivisions within the city’s jurisdiction, but in no case shall these standards be less than the accepted policies of the State Department of Transportation, Division of Highways, as taken or modified from the American Association of State Highway and Transportation Officials (AASHTO) manuals.
(1) Generally.
(a) All new proposed street systems within a subdivision shall be coordinated with the existing street or road system surrounding the subdivision.
(b) Minor thoroughfares, local streets and cul-de-sacs shall be so laid out that their use by through traffic will be discouraged.
(c) Where in the opinion of the Planning Board, it is necessary to provide for street access to an adjoining property, proposed streets shall be extended by platting to the boundary of the property and a temporary turnaround shall be provided.
(d) Private streets not open to public use shall be prohibited within any platted subdivision.
(e) When a subdivision abuts a major thoroughfare or principal arterial street, the subdivider may be required to construct a frontage road, or in most instances reverse frontage on a minor street for the lots to be developed adjacent to the thoroughfare. Where reverse frontage is established, private driveways shall be prevented from having direct access to the thoroughfare.
(f) Street names which duplicate or are phonetically similar to existing street names shall be prohibited. A proposed street which is in alignment with an existing street shall bear the name of the existing street.
(g) When a tract of land is subdivided into lots which are larger than the norm, the lots will be designed and arranged so that they allow for future opening of streets and further logical subdivision.
(h) Subdividers shall implement a subdivision street system that connects in at least two
separate areas with an existing street or road system surrounding the subdivision and will allow emergency vehicles easily to access the subdivision other than by the primary entrance to the subdivision.
(2) Street classification. In all new subdivisions, streets that are dedicated to public use shall be classified as provided herein.
(a) The classification shall be based upon the projected volume of traffic to be carried by the street, stated in terms of the number of trips per day.
(b) The number of dwelling units to be served by the street may be used as a useful indicator of the number of trips but is not conclusive.
(c) Whenever a subdivision street continues an existing street that formerly terminated outside the subdivision or it is expected that a subdivision street be continued beyond the subdivision at some future time, the classification of the street will be based upon the street in its entirety, both within and outside of the subdivision.
(d) The classification of streets shall be as listed in Table 158-1:
Arterial street | A major street in the city’s street system that serves as an avenue for the circulation of traffic into, out, or around the city and carries high volumes of traffic. |
Collector street | A street whose principal function is to carry traffic between minor, local and arterial streets but that may also provide direct access to abutting properties. It serves or is designed to serve, directly or indirectly, more than 100 units and is designed to be used or is used to carry more than 800 trips per day. |
Cul-de-sac | A street which serves abutting residential land use and which terminates in a turnaround and originates at the intersection with another street. |
Local Street | A street whose sole function is to provide access to abutting properties. It serves or is designed to serve at least ten but not more than 25 dwelling units and is expected to or does handle between 75 and 200 trips per day. |
Marginal access | A street that is parallel to and adjacent to an arterial street and that is designed to provide access to abutting properties so that these properties are somewhat sheltered from the effects of the through traffic on the arterial street and so that the flow of traffic on the arterial street is not impeded by direct driveway access from a large number of abutting properties. |
Note: Other street types are defined and listed in detail in the City Technical Design and Specifications Manual. | |
(3) Right-of-way.
(a) Minimum street right-of-way widths shall not be less than the following in Table 158-2:
Collector street | 60 feet* |
Cul-de-sac | 60 feet* |
Cul-de-sac turnaround | 100 feet (diameter) |
Frontage road | 60 feet* |
Local street | 60 feet* |
Major thoroughfares | 200 feet |
Marginal access | 80 feet* |
Minor thoroughfares | 80 feet* |
US 70 and NC 101 | 200 feet |
Notes to table: | |
*Or greater as required to accommodate drainage, on-street parking, sidewalks and/or multi-use paths. | |
(b) The subdivider will only be required to dedicate a maximum of 100 feet of right-of-way. In cases where over 100 feet of right-of-way is desired, the subdivider will be required to reserve the amount in excess of 100 feet. In all cases in which right-of-way is sought for an access controlled facility, the subdivider will only be required to make a reservation.
(4) Pavement widths with curb and gutter. All streets shall be constructed with curb and gutter and shall conform to the other requirements in this section. Considerations may be given to alternative methods for street installation, however it must be substantiated that is not feasible to install curb and gutter. This shall be proven by the design professional prior to submittal of the preliminary plat. Minimum pavement width shall not be less than the following in Table 158-3, when utilizing curb and gutter:
(5) Pavement widths with swale drainage. Minimum pavement width shall not be less than the following in Table 158-4 when utilizing swale drainage:
(6) Pavement construction.
(a) Pavement construction shall be in accordance with the most current accepted standards of the State Department of Transportation, Division of Highways and city policy.
(b) Streets shall be marked in accordance with the applicable provisions of the North Carolina Department of Transportation Highway Marking Manual and supplement to the Manual on Uniform Traffic Control Devices for Streets and Highways, as amended from time to time.
(7) Design and geometric characteristics.
(a) The standards outlined below shall apply to all subdivision streets proposed for addition to the state highway system or municipal street system.
(b) In cases where a subdivision is sought adjacent to a proposed thoroughfare corridor, the requirements of dedication and reservation discussed under right-of-way shall apply.
(a) Design speed. The design speeds for subdivision-type streets shall be as noted in Table 158-5:
(b) Geometry. When a continuous street center line deflects at any point by more than three degrees, a circular curve shall be introduced, having a radius of curvature on the center line of not less than the following in Table 158-6:
(c) Tangents. A tangent at least 100 feet long shall be provided between reverse curves on all streets.
(d) Right angles. Streets shall be laid out so as to intersect as nearly as possible at right angles and a street shall not intersect any other street at less than 60 degrees.
(e) Jogs. Street jogs with center line offsets of less than 125 feet on major or collector streets shall be avoided.
(f) Intersections. Intersections with a major highway shall be at least 800 feet apart.
(g) Property lines at street intersections. Property lines at street intersections shall be rounded with a minimum radius of 20 feet or of a greater radius when required by the Planning Board.
(h) Cul-de-sac and dead-end streets.
1. In general, streets designed to have one end permanently closed shall be avoided unless it is clear that a through street is not essential to the street system of the area.
2. Cul-de-sac and permanent dead-end streets shall have:
a. A turnaround at the closed end with the diameters specified for a cul-de-sac turnaround in divisions (C)(3) through (C)(5) above; and
b. A length not longer than the total number of feet shown on the following table, where this length is measured from the street intersection (including an intersection with another cul-de-sac or dead-end street) nearest the closed end to the closed end as noted in Table 158-7 below:
(i) Service drives or alleys. Service drives or alleys shall be required to serve lots used for commercial and industrial purposes except that this requirement may be waived where other definite and assured provision is made for service access.
(j) Curbs, gutters and curb cuts.
1. Curbs and gutters shall be installed by the developer in accordance with accepted construction standards as specified in Roadway Standards, State Department of Transportation and in accordance with city policy.
2. Where curbs and curb cuts are installed, the facilities shall comply with G.S. § 136-44.14 concerning curb cuts with respect to handicapped persons.
(D) Street name signs. Appropriate street name signs which meet the Manual on Uniform Traffic Control Devices (MUTCD) shall be installed by the developer at all street intersections. Names of streets shall be reviewed and recommended for approval by the city’s GIS Department before adoption of the final plat.
(E) Stop and yield signs. Stop and yield traffic signs shall be installed by the developer at appropriate street intersections as required by the city, or State Department of Transportation, Division of Highways.
(F) Street lighting.
(1) Lighting plan. Before final approval of a subdivision plat, the developer shall present a street lighting plan, formulated with the aid of the local utility serving the area in which the subdivision is being developed. Street lights shall be installed at every intersection, or cul-de-sac, and at intervals of no less than 500 feet between intersections in residential areas. Additional street lights shall be installed in accordance with city policy.
(2) Rental costs. Rental costs of street lights, if within the city shall be assumed by the city. Rental costs of street lights, if outside the city limits, shall be assumed by the subdivider or property owner.
