§ 155.015 SUBDIVISION ROADS.
   (A)   General.
      (1)   A subdivision road is one that serves a parcel or tract of land that is subdivided into two or more lots, building sites or other divisions for sale or building development for residential purposes where the subdivisions include a new road or change in an existing road.
      (2)   Subdivision roads shall be designated public or private. Public designations shall be built to minimum construction standards of the State Department of Transportation as required under G.S. § 136-102.6. (See § 155.017.) Private roads need not meet minimum construction requirements, but must meet minimum construction requirements before ever becoming a part of the state maintained system.
   (B)   Definitions. For the purpose of this section, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
      LOCAL RESIDENTIAL SUBDIVISION ROAD. Either cul-de-sacs, loop roads, roads that do not connect thoroughfares or serve major traffic generators.
         (a)   CUL-DE-SACS. These are very short roads, open at one end only, with a special provision for turning around. They have a "bulb" end design with a specific turning radii and a limited number of lots.
         (b)   DEAD END ROADS. These are roads less than 2,500 feet in length, open at one end only without special provisions for turning around and have no collector characteristics.
         (c)   LOOP ROADS. A road that has its beginning and ending points on the same route. It is less than one mile in length and has no collector characteristics.
         (d)   OTHER ROADS. These roads do not connect thoroughfares or serve major traffic generators and do not have "collector" characteristics.
         (e)   SHORT CONNECTING ROADS. These roads are normally one block long or extend on a block-by-block basis and have no collector characteristics.
      RESIDENTIAL COLLECTOR ROADS. A road which serves as the connecting street between local residential roads and the thoroughfare system.
         (a)   CONNECTING ROADS. The roads which serve as the connecting road system between other roads within the subdivision and the thoroughfare system.
         (b)   DEAD END ROADS. These roads are more than 2,500 feet in length, open at one end only without special provisions for turning around, and have collector characteristics.
         (c)   LOOP ROADS. A road that has its beginning and ending points on the same route. It is more than one mile in length and has collector characteristics.
         (d)   OTHER ROADS. These are other roads having a "collector" type function in the thoroughfare system.
         (e)   SUBDIVISION ACCESS ROAD. This is a road built through vacant property to provide access to the property being developed. This road would not have lots platted along it.
   (C)   Requirements for addition of subdivision roads to the system.
      (1)   The minimum construction standards and other requirements in this chapter must be a part of the proposal to be reviewed for approval prior to development in order for a plat to be recorded by the County Register of Deeds.
      (2)   A petition for addition (DOT Form SR-1) is required from the developer and/or property owners. (See § 155.018.)
      (3)   Developers or property owners must dedicate the right-of-way, as indicated in the minimum design and construction criteria section of this chapter, free of charge and clear of all encumbrances.
      (4)   Utility adjustments or relocation to conform to Division of Highways' requirements (see Policy and Procedures for Accommodating Utility on Highway Rights-of-Way) shall be made at no expense to the Division of Highways. Existing and/or relocated utilities may remain within the right-of-way of any subdivision road added to the secondary road system; provided, the location of same meets Division of Highways' approval and further provided the utility owner executes an encroachment agreement on forms furnished by the Division of Highways. As per G.S. § 136-102.6, "Utilities are defined as electric power, telephone, television, telegraph, water, sewage, gas, oil, petroleum products, steam, chemicals, drainage, irrigation and similar lines". G.S. § 136-102.6 dictates further that "The right of any utility placed or located on a proposed or existing subdivision public road right-of-way shall be subordinate to the road right-of-way, and the utility shall be subject to regulation by the Board of Transportation". NOTE: The developer and/or owners will be required to submit encroachment agreements for all utilities within a subdivision as dictated by G.S. § 136-102.6. (See § 155.017.)
      (5)   At least 20% of the lots bordering the road must be individually owned.
      (6)   There must be at least two occupied residences for each one-tenth of a mile. A minimum of four occupied homes is required for the addition of roads less than two-tenths of a mile in length. If four occupied homes are not served, it will be treated as a private drive. An exception may be made if the cul-de-sac is fully developed, serves at least four platted lots, and has four occupied homes that abut the road. A minimum of two homes must have primary access to the cul-de-sacs.
      (7)   Subdivision access roads must provide ingress and egress for at least five occupied residences for roads less than one mile in length and an average of five occupied residences per mile for roads over one mile in length.
      (8)   The number of platted lots on each road will be reviewed to ensure that the minimum occupied housing requirements in this chapter are served.
      (9)   Connecting roads with less than the required occupied homes for the length involved may be reviewed as to traffic usage for addition purposes. Traffic usage equivalent to the traffic that would be generated by the correct number of occupied homes will be acceptable.
      (10)   Any subdivision road with a right-of-way dedicated, recorded, or that has preliminary approval from a county planning board dated after 9-30-1975, will not be added to the state system unless the road is built to the minimum construction standards of the Division of Highways for subdivision roads.
      (11)   All subdivision roads shall have an acceptable permanent vegetative cover established and other acceptable permanent erosion control measures installed in accordance with Division of Highways' specifications, prior to addition to the state maintained system.
      (12)   Subdivision roads shall meet the minimum design and construction criteria contained herein prior to addition to the state system and shall be in an acceptable state of maintenance prior to addition to the state maintained road system.
      (13)   All pipe culverts, storm sewers and appurtenances shall be free of all debris and silt build-up and shall be structurally and hydraulically sound, and functioning in a normal manner. All drainage ditches shall be of such a width and depth and with such a slope as to carry the anticipated discharges. Paved ditches or rip rap shall be required where necessary.
      (14)   Where extenuating circumstances exist, the Division Engineer has the authority to allow deviations from this chapter which are reasonable, and limited only to safety, environmental and maintenance factors. No deviation will be allowed from the typical section requirements, except by written approval from the Chief Engineer-Operations.
      (15)   Within a municipal extra territorial jurisdiction or within counties having local ordinances affecting subdivisions, the more restrictive ordinance shall apply.
      (16)   Design concepts using traffic calming devices and walkable community concepts shall be reviewed by the Chief Engineer-Operations.
      (17)   For the policy on roadway bridges and dams, see § 155.036.
      (18)   Roads being considered for addition that have highway obstructions as defined in 19A N.C.A.C. § 2E.0404 will not be considered without prior approval of the Division Engineer. (See § 155.019.)
      (19)   The Division of Highways will consider the addition of streets that serve developments with large lots or parcels that are of the size that the occupied housing requirement of two homes per tenth of a mile cannot be met. The number of occupied homes needed shall be a judgment factor based upon the length and the number of lots or parcels involved. The minimum requirement shall be four occupied homes.

G.S. § 136-102.6, Compliance of subdivision streets with minimum standards of the Board of Transportation required of developers
(a)   The owner of a tract or parcel of land which is subdivided from and after October 1, 1975, into two or more lots, building sites, or other divisions for sale or building development for residents purposes, where such subdivision includes a new street or the changing of an existing street, shall record a map or plat of the subdivision with the Register of Deeds of the county in which the land is located. The map or plat shall be recorded prior to any conveyance of a portion of said land, by reference to said map or plat.
(b)   The right-of-way of any new street or change in an existing street shall be delineated upon the map or plat with particularity and such streets shall be designated to be either public or private. A street designated on the plat or map as public shall be conclusively presumed to be an offer of dedication to the public of such street.
(c)   The right-of-way and design of streets designated as public shall be in accordance with the minimum right-of-way and construction standards established by the Board of Transportation for acceptance on the State highway system. If a municipal or county subdivision control ordinance is in effect in the area proposed for subdivision, the map or plat required by this section shall not be recorded by the Register of Deeds until after it has received final plat approval by the municipality or county, an until after it has received a certificate of approval by the Division of Highways as herein provided as to those streets regulated in subsection (g). The certificate of approval may be issued by a District Engineer of the Division of Highways of the Department of Transportation.
(d)   The right-of-way and construction plans for such public streets in residential subdivisions, including plans for street drainage, shall be submitted to the Division of Highways for review and approval prior to the recording of the subdivision plat in the office of the Register of Deeds. The plat or map required by this section shall not be recorded by the Register of Deeds without a certificate of approval by the Division of Highways of the plans for the public street as being in accordance with the minimum standards of the Board of Transportation for acceptance of the subdivision street on the State highway system for maintenance. The certificate of approval shall not be deemed as acceptance of the dedication of such streets on the subdivision plat or map. Final acceptance by the Division of Highways of such public streets and placing them on the State highway system for maintenance shall be conclusive proof that the streets have been constructed according to the minimum standards of the Board of Transportation.
(e)   No person or firm shall place or erect any utility in, over, or upon the existing or proposed right-of way of any street in a subdivision to which this section applies, except in accordance with the Division of Highway's policies and procedures for accommodating utilities on highway rights-of way, until the Division of Highways has given written approval of the location of such utilities. Written approval may be in the form of exchange of correspondence until such times as it is requested to add the street or streets to the State system, at which time an encroachment agreement furnished by the Division of Highways must be executed between the owner of the utility and the Division of Highways.
The right of any utility placed or located on a proposed or existing subdivision public street right-of way shall be subordinate to the street right-of-way, and the utility shall be subject to regulation by the Department of Transportation. Utilities are defined as electric power, telephone, television, telegraph, water, sewage, gas, oil, petroleum products, steam, chemicals, drainage, irrigation, and similar lines. Any utility installed in a subdivision street not in accordance with the Division of Highways, accommodation policy, and without prior approval by the Division of Highways, shall be removed or relocated at no expense to the Division of Highways.
(f)   Prior to entering any agreement or any conveyance with any prospective buyer, the developer ant seller shall prepare and sign, and the buyer of the subject real estate shall receive and sign an acknowledgment of receipt of a separate instrument known as the subdivision streets disclosure statement (hereinafter referred to as disclosure statement.)
