Section 507.5.2 of the IFC is deleted in its entirety and replaced as follows:

Fire hydrant systems shall be subject to periodic tests as required by the fire marshal. Fire hydrant systems shall be maintained in an operative condition at all times and shall be repaired where defective. Additions, repairs, alterations and servicing shall comply with approved standards. The standards contained in this section apply to all new hydrant installations and to replacement of existing hydrants on public water systems that are required by the IFC to provide fire flow.

(1) The installation of all fire hydrants shall be in accordance with sound engineering practices and supplied by mains as prescribed by this chapter. Hydrants shall be installed, tested and charged prior to the start of construction, unless otherwise approved by the fire marshal.

(2) Approval of fire hydrant types must be obtained prior to installation from the water purveyor, or the fire marshal in the absence of a water purveyor.

(3) All elements of fire hydrant installation including water mains, pipes, valves, and related components shall conform to the fire code, National Fire Protection Association (NFPA) Standard 24, and American Water Works Association (AWWA) Standard C502-94.

(4) Standard hydrants shall have not less than five-inch main valve openings (MVO) with two two-and-one-half inch National Hose (N.H.) outlet ports and one four-and-one-half inch N.H. outlet port. When two port hydrants are replaced, they shall be replaced with three port hydrants.

(5) "Storz" type steamer port fittings shall be provided on new hydrants when required by the local fire district.

(6) 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 above the grade. There shall be a 36-inch radius of clear area about the hydrant for the operation of a hydrant wrench on the outlets and the control valve. The pumper port shall face the street, or where the street cannot be clearly identified, the port shall face the most likely route of approach of the fire truck while pumping, as determined by the fire marshal. The hydrant shall be installed within 15 feet of the street or access roadway.

(7) Hydrants shall be a minimum of 50 feet from a commercial structure to be served and no further than 100 feet from a fire department connection (FDC) if present.

(8) The hydrant lateral shall be designed to deliver the required fire flow.

(10) Fire hydrant systems shall be maintained in an operative condition at all times and shall be repaired where defective. Additions, repairs, alterations and servicing shall be in accordance with approved standards. Fire hydrant systems shall be subject to such periodic tests as required by the fire marshal.

(11) When any portion of the facility or building protected is in excess of 150 feet from a water supply on a public street, as measured by an approved route around the exterior of the facility or building, on-site fire hydrants and mains capable of supplying the required fire flow shall be provided when required by the fire marshal.

(12) The fire district may, in accordance with an agreement with the water purveyor, test hydrants for flow capability.

(13) For all new hydrant installations, either public or private, the developer shall color code the tops of the hydrant(s) to designate the level of service being provided by that hydrant. Color coding for existing and new hydrants shall be in accordance with SCC Table 30.53A.520(13).

(14) For all new hydrant installations, either public or private, the developer shall install blue street reflectors to indicate hydrant locations. Installation of blue street reflectors shall be completed prior to final approval of any development or new construction.

(15) Maintenance of public hydrants shall be the responsibility of the recognized water purveyor. Private fire service hydrants and mains shall be protected and maintained by the owners in accordance with NFPA Standard 24.

(16) The water purveyor shall submit documentation to the fire marshal indicating which entity is responsible for proper installation, operation and maintenance of fire protection facilities associated with public water systems. The statement shall also indicate which fire district or utility is responsible for repair and maintenance of fire hydrants in unincorporated Snohomish County.

(17) Vehicles shall not be parked within 15 feet of a fire hydrant, or fire department connection, or a fire protection system control valve.
