(a) Water and sanitary sewer systems. Each lot in all subdivisions within the corporate limits of the city shall be provided, at the subdivider's expense, with an extension of the municipal water and sanitary sewer systems. Outside the corporate limits, if water and/or sewer systems are in the area of the new subdivision, the proposed subdivision must use these facilities, whichever is available. If these facilities are not available, then well and/or septic systems may be used.
(b) Storm water drainage system. The subdivider shall provide a surface water drainage system constructed to the city’s standard specification, subject to review by the City Engineer.
(1) No surface water shall be channeled or directed into a sanitary sewer.
(2) Where feasible, the subdivider shall connect to an existing storm water drainage system.
(3) Where an existing storm water drainage system cannot feasibly be extended to the subdivision, a surface drainage system shall be designed to protect the proposed development from water damage.
(4) Surface drainage courses shall have side slopes of at least three feet of horizontal distance for each one foot of vertical distance, and courses shall be of sufficient size to accommodate the drainage area without flooding, and designed to comply with the standards and specifications for erosion control of the North Carolina Sedimentation Pollution Control Act, G.S. 143-34.12, Chapter 113A, Article 4 and the N.C. Administrative Code Title 15, Chapter 4, and any locally adopted erosion and sedimentation control ordinances.
(5) The minimum grade along the bottom of a surface drainage course shall be a vertical fall of at least one foot in each 200 feet of horizontal distance.
(6) Streambanks and channels downstream from any land disturbing activity shall be protected from increased degradation from accelerated erosion caused by increased velocity of runoff from the land disturbing activity in accordance with the North Carolina Sedimentation Pollution Control Act, G.S. 143-34.12, Chapter 113A, Article 4 and the North Carolina Administrative Code Title 15, Chapter 4.
(7) Anyone constructing a dam or impoundment within the subdivision must comply with the North Carolina Administrative Code Title 15, Subchapter 2 K.
(8) In all areas of special flood hazards, all subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage.
(9) Where feasible, other utilities, including electric and telephone lines, must be located underground and avoid mature tree root systems. If there are topographic or geologic hindrances to placing these utilities underground, then in accordance with Section 9-4-64-7 of this chapter, overhead utility poles may be used. The subdivider must provide factual evidence to the City Planner before receiving permission to use overheard utilities.
