(A) Dedication of right-of-way. Right-of-way for public streets shall be dedicated to the town pursuant to G.S. Ch. 160A, Art. 19, Part 2, and other applicable state laws. When dedication cannot be required, any future street right-of-way indicated on adopted thoroughfare plans or collector street plans shall be shown on the plat.
(B) Conformance with thoroughfare plans and collector street plans. The location and design of streets shall be in conformance with applicable thoroughfare plans and collector street plans. Where conditions warrant, right-of-way widths and pavement widths in excess of the minimum street standards may be required.
(C) Conformance with adjoining street systems. The planned street layout of a proposed subdivision shall be compatible with existing or proposed streets and their classifications on adjoining or nearby tracts.
(D) Access to adjoining property. Where in the opinion of the approving body, it is desirable to provide for street access to adjoining property, proposed streets shall be extended to the boundary of such property. The minimum number of points of street access shall be based on the number of dwelling units in the proposed development as set forth below:
(1) Residential developments with more than 50 lots or dwelling units shall have at least two separate points of public road access.
(2) Residential developments with more than 150 lots or dwelling units shall have at least three separate points of public road access.
(E) Reserve strips. Reserve strips adjoining street rights-of-way for the purpose of preventing access to adjacent property shall not be permitted under any condition.
(F) Street classification. The final determination of the classification of streets in a proposed subdivision shall be made by the town. Street classifications are defined in § 152.012 of this chapter.
(G) Public street design criteria. Public streets shall be constructed in accordance with the standards contained in the NCDOT Roadway Design Manual or the NCDOT Subdivision Roads Minimum Construction Standards, as appropriate.
(H) Private street design criteria.
(1) Where permitted. Private streets shall be permitted in single-family detached residential developments, townhouses developments and in residential developments that are gated or otherwise secured self-contained developments that have their access to public street(s) at one or more secured points.
(2) Design and construction. The pavement, construction and design standards for all private streets will be equivalent to the standards for local residential streets unless the developer supplies an alternate pavement design (supported by an engineering study) approved by the town. The developer must furnish an engineer’s seal and certification that the private streets have been tested and certified for the subgrade, base and asphalt. Common area may need to be widened to include the side ditch section. All cul-de-sacs shall have a minimum 40-foot pavement radius.
(3) Through streets. No through street in a residential area connecting two public streets can be designated as a private street.
(4) Connections to public streets. All private streets connecting with public streets require approved driveway applications from the town (or NCDOT if applicable).
(5) Sidewalks. Where sidewalks are installed, they shall be in accordance with all applicable standards as specified in this chapter and shall meet or exceed the town’s standard specifications for sidewalks.
(I) Street intersections. Street intersections shall be as nearly at right angles as possible. Property lines at street intersections shall be a tangent connecting points on each right-of-way line, which are located a minimum distance of 20 feet back from the intersection of the two right-of-way lines in residentially zoned areas and 50 feet in non-residential zoned areas.
(J) Streets crossing natural areas. All streets crossing natural areas, wetlands or streams shall cross at or as near to 90 degrees as possible within topographic limits.
(K) Spacing between intersections. Offset intersections are not desirable and should be avoided. Intersections that cannot be aligned should be separated in accordance with the design standards established by street classification. The higher classification street involved shall determine the distance between intersections along that street. In the event of unusual topography, a distance less than the design standard, but in no case less than 150 feet, may be allowed by the approving body.
(L) Maximum length of blocks and cul-de-sacs. The maximum length of a block and the maximum distance from an intersecting through street to the end of a cul-de-sac shall be 1,000 feet.
(M) Temporary turnarounds. Streets stubbed to adjoining property or to phase lines may be required to have temporary turnarounds at the end of the street sufficient to permit sanitation vehicles to turn around.
(N) Grades at intersections. The grade on stop streets approaching an intersection shall not exceed 5% for a distance of 100 feet from the centerline of the intersection.
(O) Street names. Street names, prefixes, suffixes and addresses shall conform to the guidelines and policies set forth by the county’s E-911 street naming and addressing standards.
(P) Street and traffic-control signs.
(1) Street signs.
(a) The town shall erect street name signs at each intersection of public streets. Public street signs shall contain white lettering on a green background. The town shall be reimbursed by the developer for the expense of installing these signs.
(b) At each intersection of a named private street or drive with a public street, the town shall erect a street name sign and the developer shall reimburse the town for the expense of installing the sign.
(c) At each intersection between private streets or drives, the developer shall be required to erect and maintain signs fabricated with retroreflective material, with green lettering on a white background as approved by the town.
(2) Traffic-control signs. The developer shall provide traffic control signs that meet the Manual on Uniform Traffic Control Devices (MUTCD) standards in locations designated by the town.
(3) Maintenance. Maintenance of signs on private streets or drives shall be the responsibility of the owner or owners’ association, as appropriate.
