(1) Utility easements shall be at least 20 feet wide, and shall run alongside or rear lot lines. Wider easements may be required if the topography along the proposed right-of-way is such that maintenance equipment cannot reasonably operate within the minimum 20-foot wide easement.
(2) Where a subdivision is traversed by a water-course, drainage way, channel, or stream, there shall be provided a stormwater easement or drainage right-of-way, conforming substantially with the lines of such watercourses, and of such further width or construction, or both, as will be adequate for the purpose. Lakes, ponds, watercourses, and the land immediately adjacent thereto shall be considered for maintenance by the town only if sufficient land is dedicated as a public recreation area or park, or if such area constitutes a necessary part of the drainage control system. The town reserves the right to reject any intended dedications.
(B) Ownership of utilities. All water, sanitary sewerage, electrical (when in town's service area) and storm drainage facilities installed under the requirements of this chapter shall become the sole property of the town upon acceptance. A deed to the town for such facilities, including easements pertaining to right-of-way entrance for maintenance, shall be executed prior to connections to the respective municipal systems.
(C) Required additional capacity. Where the Town Council deems it necessary, in the interest of the health, safety and general welfare of the residents of the town and its extraterritorial jurisdiction, the applicant shall make certain improvements at sizes in excess of those which would normally be required to serve only the applicant's subdivision. Where oversized improvements are required, the town shall reimburse the applicant for the cost of materials incurred over and above those required to serve the applicant's subdivision. Such reimbursement shall be mutually agreed upon through a reimbursement agreement as authorized by G.S. § 160A-499.
(D) Water distribution lines and sanitary sewers.
(1) Each lot in all subdivisions within the town's corporate limits, and each lot in all subdivisions in the extraterritorial jurisdiction within 300 feet of the town's water and/or sanitary sewer system shall be connected at the applicant's expense to the town's water and/or sewer system. In accordance with § 51.03(A) of the Town Code of Ordinances, each developer of land shall be responsible for providing water and sewer line connections and all necessary pump stations, lift stations, and fire hydrants between their property and the town systems. In accordance with § 50.02 of the Town Code of Ordinances, the applicant shall pay water and sewer system development fees for all property to be served by a connection to the town's water and/or sanitary sewer system.
(2) Where a subdivision, in the extraterritorial jurisdiction lies more than 300 feet from the municipal water and/or sewer system, the applicant may, at the applicant's expense, connect the subdivision lots to the town's water and/or sanitary sewer system. In accordance with section § 51.20(A) of the Town Code of Ordinances, any property owner or developer desiring to have water or sanitary sewer services extended to and along any public street or other area where no water or sanitary sewer main exists shall apply to the Town Manager, or designee, in writing requesting a specific daily allocation for such services. If the applicant provides a community water and/or sewer system, rather than connecting to the municipal system, or provides individual wells and/or septic tanks, the materials, design, and installation shall be made in accordance with all applicable state and Johnston County specifications and standards.
(3) In accordance with section § 51.03(D) of the Town Code of Ordinances, the minimum diameter of a water main shall be six inches and the minimum diameter for a sewer main shall be eight inches. All sewer mains shall be installed at a maximum depth to ensure service to as large an area as possible. Water distribution lines shall be no smaller in size than six inches nominal diameter, with the following exception: On cul-de-sacs which are served by fire hydrants at their intersection with a local street, and the hydrant is connected to a water line of six inches nominal diameter, or larger, water service may be provided with lines smaller than six inches if a blow-off valve is established at the end of such line, or the line is connected to another line within the subdivision to form a loop. This exception shall not apply where such line represents the interconnection between the subdivision and the municipal system. On streets which are "stubbed out" at property lines to permit future development, service must be provided by lines of at least six inches nominal diameter.
(4) In accordance with section § 155.301(F)(6)(a) and Title V of the Town Code of Ordinances, an accessible, adequate, safe supply of water and sewer shall be provided in each manufactured home park.
(5) For the purpose of this section, the term "water system" shall include all appurtenances and fixtures normally associated with such facilities, including fire hydrants, gate valves, blow-offs, manholes, and pumping apparatus, but shall not include individual service meters, which shall be installed by the town; the aforementioned appurtenances and fixtures shall comply with the specifications and standards of the town.
(E) Storm drainage.
(1) The applicant shall provide an adequate drainage system for the proper drainage of all surface water in order to protect the proposed development from water damage. The design of such system shall be subject to the approval of the Town Engineer.
(2) No surface water shall be channeled or directed into a sanitary sewer.
(3) Where feasible, the applicant shall connect to the municipal storm drainage system.
(4) Where the municipal storm drainage system cannot feasibly be extended to the subdivision, a surface drainage system shall be designed to complement surface drainage systems to surrounding properties.
(5) Cross pipes under streets and driveways shall be concrete, reinforced concrete, or other pipe, as approved by the Town Engineer. All such cross pipes shall be a minimum of 15 inches in diameter.
(6) Surface drainage courses shall have side slopes of at least one foot of horizontal distance for each foot of vertical distance.
(7) The minimum grade along the bottom of a surface drainage course shall be a vertical fall of approximately one foot in each 300 feet of horizontal distance.
(F) Electrical utilities. Electrical improvements in accordance with town or progress energy standards, whichever is applicable, shall be required in all subdivisions.
