Article V. Use Regulations
11.8 Planned Unit Developments
11.8.3 Design Guidelines
A. Minimum Dimensional & Amenity Requirements
This Section describes additional regulations that shall be met for single family, multifamily, and nonresidential uses within planned unit developments. The regulations shall be applied
individually by the desired type of use and density per pod. The developer shall outline which method is intended as part of the application and shall provide a clear intent to seamlessly
integrate differing requirements.

Superior Design Criteria
F. Public Safety & Service Availability
Availability of public services is a major factor in locating developments. For purposes of this item, public services may include, but not limited to, the use of residential sprinkler
systems, and proximity to fire and emergency medical services, hospitals, law enforcement services, libraries, and educational facilities.
Article VII. Development Design Guidelines
6.4 Fire Protection
6.4.1 General Fire Hydrant Requirements
Adequate fire protection shall be provided to all new subdivision developments and nonresidential new construction and expansions. Where an adequate public water supply system is available,
The developer or subdivider shall install fire hydrants in such a manner that the development is afforded adequate fire protection. or as provided in this Ordinance. The regulations
contained herein are intended to facilitate proper installation of required fire protection measures. ; no guarantee is made that fire projection will be available upon installation
of improvements in compliance with this Section.
All hydrants shall be Harnett County Public Utilities and Fire Code Official approved, in accordance with the requirements of this Section.
No fire hydrant shall be installed on less than a 6 inch (6”) main.
Hydrants shall have two (2) two and one half inch (2 ½”) and one (1) four and one half inch (4 ½”) connections with threads of the National Pipe Thread (NPT) type.
The upper hydrant operation stem within the bonnet shall be sealed and lubricated by means of an oil or grease bath, unless otherwise approved. The operating nut shall be pentagonal
type measuring one and one half inch (1 ½”) from point to flat. Hydrants shall open left.
All hydrants shall be furnished with barrel and stem extensions as required for the final field location. Nominal minimum bury will be a depth of three and one half (3 ½) feet. All
hydrants at finish grade shall measure 18 inches (18”) from ground to center of steamer cap.
Water lines servicing fire hydrants shall have at least 500 gallons of water flow per minute.
The Fire Code Official shall approve all hydrant types and locations in new developments and any alterations to this Ordinance related to fire hydrants and fire protection.
All fire hydrants shall be located on the right side of the roadway in which responding fire apparatus would travel into subdivisions, beginning at the main entrance to the subdivision.
6.4.2 …to remain as is existing within the U.D.O.
6.4.3 …to remain as is existing within the U.D.O.
Residential Sprinklers
Where the provisions outlined above do not facilitate adequate fire protection, i.e. 500 gallons of water flow per minute, for the purposes of this Ordinance, residential sprinklers
shall be required. In such cases, the Director of Public Utilities and Fire Code Official may reduce the required water line size and increase fire hydrant spacing. The required fire
flow (as defined by gallons per minute) shall be determined during the design of the system by a professional qualified to do such work. Upon installation of the water supply infrastructure,
the actual fire flow shall be determined on site by a professional qualified to do such work and Fire Service Personnel using an approved method.
