(Ord. 775, Sec. 16, 2008)
14.84.050 Hydrants to be Served by Recognized Water Purveyor.
All water mains and fire hydrants required hereunder shall be served by a recognized water purveyor, or in the absence of such, by alternate method(s) as approved by the Fire Marshal, except residential accessory buildings classified under the International Building Code as U with a lot size of 20,000 square feet or greater, whether platted or unplatted, provided there is no conflict with the requirements of the recognized water purveyor serving the building site. (Ord. 775, Sec. 16, 2008)
14.84.060 Hydrant Standards.
(a) Every development (subdivided or unsubdivided) that is served by a public water system shall include a system of fire hydrants sufficient to provide adequate fire protection for the buildings located or intended to be located within such development.
(b) The presumption established by this chapter is that to satisfy the standard set forth in subsection (c) of this section.
(c) The following hydrant standards shall apply as set forth herein unless waived or modified pursuant to Section 14.84.100 (Waiver and Modification).
(1) Type. Any new hydrant installations under this chapter shall have not less than a five-inch main valve opening, two hose outlets having nominal diameters of two and one-half inches National Standard Thread (NST), and one engine port outlet having a nominal diameter of four and one-half inches NST fitted with a four-inch Stortz coupling. All hydrant threads shall be National Standard Threads with seven and one-half threads per inch for two-and-one-half-inch hose outlets and four threads per inch for four-and-one-half-inch engine port outlets. Water lines that serve hydrants shall be at least six-inch lines, and, unless no other practicable alternative is available, no such lines shall be dead-end lines. If the hydrant is connected to a dead-end main line, the dead-end lines shall be a minimum of eight inches to the hydrant tee, or larger if necessary to provide required fire flows and be approved by the local water purveyor and the Fire Marshal.
(2) Spacing.
(i) Within areas exclusively developed or being exclusively developed for R-3 or U occupancy, maximum distance from a fire hydrant to a dwelling unit shall be 300 feet along a roadway. The maximum distance between hydrants in residential areas shall be no greater than 600 feet.
(ii) For all other occupancy types, the maximum distance from a fire hydrant to a dwelling unit shall be 150 feet along a roadway.
(iii) When any portion of a commercial structure to be protected is in excess of 150 feet from the water supply on a public street and when required by the Fire Marshal, there shall be provided on-site fire hydrants and mains capable of supplying the required fire flow. Water supply may consist of reservoirs, pressure tanks, elevator tanks, water mains or other fixed systems capable of supplying the required fire flow as approved by the Fire Marshal and the recognized water purveyor having jurisdiction over said project.
(3) Location.
(i) Whenever possible, hydrants shall be located at street intersections; provided, that when such location results in spacing distances greater than allowed by this section, additional hydrants may be required between intersections; provided further, that when the required fire flow is greater than 2,000 gallons per minute (GPM), the number and location of hydrants shall be approved by the Fire Marshal.
(ii) For commercial buildings:
a. The minimum number of public and private hydrants required shall be determined by dividing the required fire flow for the building by 1,000.
b. Hydrants shall be located no closer than 50 feet to any served building and at no greater distance than 300 feet from any portion thereof.
c. A hydrant shall be located not more than 100 feet from a sprinkler or standpipe connection.
(iii) All hydrants shall be accessible to Fire Department apparatus by roadways meeting the requirements of Section 503 of the IFC 2006 Edition.
(iv) When fire protection facilities are to be installed by the developer or permittee, such facilities shall be installed prior to any combustible construction being installed on site. Water mains and fire hydrants shall be capable of delivering the required fire flow to the site and shall remain the responsibility of the developer until accepted by the recognized water purveyors. When alternate provisions for protection are provided pursuant to Section 14.84.100 (Waiver and Modification) the above requirements may be waived or modified.
(v) When locating hydrants, consideration shall be given to:
a. Hazardous operations and the practicality of sound fire service practices (fences, roadways, barriers to operation, etc.);
b. The recommended location preferred by the purveyor;
c. The required five-foot vehicle clear zone on each side of each hydrant.
(4) Installation. Hydrants shall stand plumb and be set to the finished grade. The bottom of the lowest outlet of the hydrant shall be no less than 18 inches or more than 36 inches above the grade. There shall be a 36-inch radius of clear area about the hydrant for the operation of hydrant wrench on the outlets and the control valve. The engine port shall face the street or, where the street cannot be clearly identified, shall face the most likely location of a fire truck while pumping, as determined by the Fire Marshal.
(d) Fire hydrants shall be protected from damage. Internal maintenance of public fire hydrants shall be the responsibility of the recognized water purveyor. Private hydrants shall be protected and maintained in accordance with NFPA 24. (Ord. 775, Sec. 16, 2008)
14.84.070 Piping and Flow Standards.
The following standards relating to water mains, hydrant branches, and fire flow shall apply, unless waived or modified, pursuant to Section 14.84.100 by the Fire Marshal:

In addition, service mains supplying hydrants shall provide the fire flow required to each building covered thereby at the number of GPM specified in IFC 2006 Edition, Appendix B, except as to single-family dwellings. The Fire Marshal may require data or design standards from a registered professional engineer, and construction in accordance therewith, in order to assure that the fire flow required will be achieved. (Ord. 775, Sec. 16, 2008)
14.84.080 Plan Approval Required.
(a) Prior to the installation of any new hydrants or mains serving hydrants, the developer shall provide plans for review to the recognized water purveyor and Fire Marshal.
(b) Upon completed installation, and acceptance by the recognized water purveyor and the Fire Marshal, the Fire Marshal shall be provided with two copies of the accurate and identifiable as-built drawings or plans showing the location of all mains, hydrant branches, valves and fire hydrants installed.
