FIRE FLOW - shall mean water flow required for fire protection purposes. 13.10.020 APPLICABILITY. All water mains and fire hydrants hereinafter installed shall meet the provisions of this Chapter as well as all other applicable plans, standards and ordinances adopted by the City of Winslow. In addition, existing hydrants not conforming with the requirements of this chapter shall, when replaced, be brought into conformance. 13.10.030 BUILDING PERMITS AND PLATS. Fire hydrants, water mains and appurtenances shall be installed as required by this chapter as a condi- tion of approval of short plats, subdivisions, planned unit developments, and mobile home parks. No building permits shall be issued for erection of any building or structure until adequate provision is made to assure that the provisions of this chap- ter will be met, including financial responsibility, provided, this section shall not apply to the recon- struction, repair, rebuilding or remodeling of a single family dwelling. 13.10,040 VARIANCE. In specific cases, a variance from the terms but within the spirit of this chapter as will not be contrary to the public interest may be granted by the Hearing Examiner upon written application of the property owner or developer, or their agent as set out in WMC 2.16.090, within 30 days of the notification to comply with this chapter. In determining to grant a variance from the terms of this chapter, including consideration of reasonable alternatives, the Hearing Examiner shall be guided by the following standards and criteria: Special conditions and circumstances exist which are peculiar to the property or structure such as size, shape, topography or location and that strict enforcement of the provisions of this chapter would deprive the property owner of rights commonly enjoyed by other properties similarly situated. The special conditions and circumstances are not primarily the result of the actions of the applicant such as structure design necessitating greater fire protection especially, as it may relate to commer- cial and multiple residential property development. Unnecessary hardships and practical difficulties which make it difficult to carry out the provisions of this chapter. Granting of the application, or providing alterna- tives to this chapter, will not be materially detri- mental to the public health, safety, morals or welfare, or injurious to the property or improvement in the vicinity of the applicant's property with particular emphasis on fire protection. The variance is necessary to make possible the reasonable development of the property. 13.10.045 NEW INSTALLATION PROCEDURES. All hydrants and water mains newly installed or replaced shall meet the following requirements: In areas already platted operational hydrants and water mains may be required to be installed in accordance with this chapter prior to the beginning of building construction. Five copies of engineered plans or drawings, accu- rately indicating main size, the location of all valves, hydrants and thrust blocks to be installed, shall be submitted to the Engineering Department with utility drawings at least fifteen (15) working days prior to the beginning of any construction. C. All construction shall conform to the City of Winslow Street and Utility Standards in effect at - 2 - the time of construction. A public works construc- tion permit shall be obtained prior to commencement of construction. The City Engineer and the Fire Department shall be notified in writing by the permit holder when the hydrant(s) and water mains will be available for use and when they are placed in service. Building construction shall not commence until plans required under this chapter have been submitted and approved in accordance with the provisions of this chapter. When water mains and hydrants are to be installed by the developer, such facilities and access roadways serving same shall be installed and made serviceable prior to and during the time of construction. No building shall be occupied until hydrants and mains for its protection are placed in service and accepted. 13.10.050 FINANCIAL RESPONSIBILITY FOR WATER MAINS The installation of water mains to properties not previously served shall be at the benefited property owner's or developer's expense. Oversized water mains required for special use demands shall be installed at the developer's or property owner's expense. If the water mains installed pursuant to subpara- graphs "A" and "B" above provide service or benefits to properties other than owned by the water main installer, latecomer agreements may be arranged between the City and the installer for the construc- tion and subsequent dedication of the water facili- ties, pursuant to the procedure established in WMC 13.16,020. Should the subdivider be required to install water mains larger than eight inches (8") in diameter to implement the development of the comprehensive plan for trunk mains to serve areas other than the subdi- vision, the City will negotiate the installation of the required water main and reimburse the subdivider for the additional cost for the larger water main. If bids are required, a percentage of cost will be determined prior to bid award. When a subdivider is required to install a water main through or adjacent to property other than his proposed subdivision, he shall not be required to install fire hydrants other than those required within his proposed subdivision. However, he shall be required to install tees in the required water main at appropriate intervals to facilitate the future installation of fire hydrants when the pro- perty adjoining this portion of the water main is subdivided or developed. 13.10,060 LOCATION. All public fire hydrants shall be installed at street intersections where possible. Public hydrant spacing shall be measured along vehicular access routes. - 3 - In single family residential areas public hydrants shall be spaced so that the average distance between them is 600 feet. Where street intersections are over 700 feet apart, additional public hydrants shall be placed between them so as not to be more than 600 feet from public hydrants on either side. If cul-de-sacs or dead end streets, road or drive- ways, or combinations thereof, are over 300 feet long, additional public hydrants shall be installed so that any portion of the street is not over 600 feet from a public hydrant. In areas zoned other than single family residential, public fire hydrants shall be installed so that the distance between them averages 300 feet. If street intersections are over 400 feet apart, additional public fire hydrants shall be placed between them so as not to be more than 300 feet apart. If cul-de- sacs or dead end streets, roads or driveways, or combinations thereof, are over 150 feet long, addi- tional public hydrants shall be installed so that any portion of the street is not over 300 feet from a public hydrant. Except single family dwellings, all buildings constructed hereafter that are located so that any portion is more than 150 feet from a street, as measured along the right of way line of vehicular access routes, shall have private fire hydrants satisfying the requirements of this chapter located at the building. The City Engineer may allow buildings having required fire flows of less than 2500 GPM's to have fire hydrants on one side of the building only, provided there shall never be less than two fire hydrants for any building larger than 5,000 square feet in first floor area including covered parking and storage. When the required fire flow is over 2500 GPM, the fire hydrants shall be served by a main which loops around the building or complex of buildings and reconnects back into a distribution supply main, and said hydrants shall be located as designated by the City Engineer. The number of fire hydrants shall be determined on an average spacing of 330 feet computed on an imaginary line parallel to and not less than 50 feet from the structure. All hydrants are to be accessi- ble to Fire Department pumpers over paved roads capable of supporting such fire apparatus. The Fire Chief shall determine the location of the hydrants based upon a determination of utility, topography and building location. Minor deviations of the hydrant distance from the building may be granted by City Engineer approval of written requests. Fire hydrant installations shall be adequately pro- tected against vehicular damage, in accordance with the standards and specifications promulgated herein. An auxiliary gate valve shall be installed at the main line tee to permit the repair and replacement of the hydrant without disruption of water service. 13.10,065 FIRE FLOW. The required fire flow shall be available at a resi- dual pressure in the mains figured for ground eleva- tion of not less than 20 PSI, except where the building is equipped with fire protection systems dependent upon the distribution mains for supply, in - 4 - which case the required fire flow shall be available at a residual pressure which will satisfactorily operate the aforementioned system, as determined by the City Engineer. Fire Flow Criteria. Required fire flows determined by the City Engineer shall be based on the criteria set forth in the Guide for Determination of Required Fire Flow, most recent edition published by the Insurance Services Office. Building Construction Classification. The following guides, published by the Insurance Services Office and the Uniform Building Code (as adopted by the City of Winslow), shall be used in calculating fire flow: INSURANCE SERVICES GUIDE UNIFORM BUILDING CODE Fire resistive Ordinary Heavy Timber Noncombustible Wood Frame I-II FR III 1 HR &III N IV HT II 1HR & II N V 1HR & V N 13.10.070 MAINS AND SERVICE LINES. All public hydrants in single family residential zoned areas shall be supplied by not less than six inch circulating water mains. All hydrants in areas other than single family residential shall be supplied by not less than eight inches circulating water mains. Dead end water mains supplying fire hydrants must be at least eight inches in diameter, with the exception of mains up to 50 feet long which may be no less than six inches in diameter. The service line from the water main to the hydrant shall be no less than six inches in diameter. Any service lines over 50 feet in length from water main to hydrant shall be no less than eight inches in diameter. The provisions of this section shall apply without exception and regardless of the size of the service main. All water mains serving or intended to serve fire protection systems, installed or replaced in the City of Winslow hereinafter shall have a minimum diameter of six inches. Provisions shall be made wherever appropriate in any project for looping all dead end or temporarily dead end mains. A minimum 15-foot easement shall be required, in addition to a temporary 10-foot con- struction easement on each side of the permanent easement. Construction plans must be approved by the City Engineer prior to the commencement of construction. The minimum water main easement width shall be fifteen (15) feet in width and shall be exclusive for the water main and appurtenances. A minimum of ten (10) feet of horizontal clearance must be maintained between a water main and any parallel sewer main. Water main extensions will be required when the property does not front on a water main or when the existing water main is not adequate for the increased use proposed. The minimum extension shall - 5 - be to a point at least five (5) feet inside the prolongation of the property line. Due to the complexities of many water mains and their interface with other underground structures, all water main construction shall be staked to insure placement within designated easements. Any deviation from this requirement shall be approved by the City Engineer. Every effort shall be made to incorporate "looped" water mains into a project. In cases where it is not possible to "loop" a new main installation, a minimum of a 2 inch blow off shall be required at all line ends. All hook-ups to fire hydrants for temporary water for whatever purpose shall be approved by the water department and will require a "temporary hydrant valve". In addition, double check valves may alo be required if a potential for contamination exists. 13.10.080 PRIVATE HYDRANTS. The installation of private hydrants as defined herein shall meet the requirements for public hydrants and shall be located as designated by the City Engineer to provide adequate fire protection. The Fire and Public Works Departments shall have the right to go upon the premises and to use the private hydrant for testing, flushing and public emergency uses. 13.10,090 FLUSH TYPE HYDRANTS. The installation of flush type hydrants is prohibited unless determined by the City Engineer that undue practical hardship would otherwise be created without relative increase in fire protection. 13.10,100 CONSTRUCTION STANDARDS. All water mains and fire hydrants hereinafter constructed in the City shall be subject to the following standards. Fire hydrants shall be the "Traffic Model" with approved breakaway features. All hydrants shall be brass to brass subseat, minimum valve opening of 5- 1/4" "o"-ring stem seal, 6" mechanical or flange shoe connection, 1-1/4 pentagonal operating nut, with two 2-1/2 inch N.S.T. hose nozzle connections and 4-1/2" pumper connection with N.S.T threads. Installation, fittings and valves. Fire hydrants shall be installed to meet sound engineering prac- tices and to the approval of the City Engineer who shall also approve the selection and use of all pipe fittings and valves. There shall be a foot valve installed between the service main and the hydrant sufficient to permit the repair and replacement of the hydrant without disruption of water service. The foot valve shall be installed to City of Winslow standards. Valves shall be furnished with a stan- dard valve box. The location of all such valves installed shall be properly and accurately marked on the as-built plans or drawings with acceptable engi- neered detail, two copies of which shall be fur- nished to the City Engineer before approval can be given by the City Council. Pipe. All water main piping shall be ductile iron pipe, cement line standard thickness class 52 unless otherwise specified, and shall conform to the standard of USA Standard A-21-51 (AWWA C151). - 6 - Fittings. Fittings shall be short body for pressure rating of 150 PSI, unless otherwise noted. All fittings shall be cement lined per USA Standard A21.4 (AWWA G104)· Valves. Gate valves. Unless otherwise specified, all valves shall be gate valves conforming to the latest revisions to AWWA standard specifications for gate valves for Ordinary Water Works Service No. C-500. They shall be iron body, bronze mounted, double disc valves with bronze wedging device and or an o-ring stuffing box. All valves shall open counter-clockwise, and unless otherwise specified, shall be a non-rising stem type equipped with standard square stem nuts. Stem nuts shall be identical with the City's existing equipment, and all valves shall be furnished with a box, cover, and marker post. Butterfly valves. Butterly valves shall be used for all lines over 8 inches in diameter. Butterfly valves shall conform to AWWA C504, Class 150, with cast iron short body and o-ring stem seal. Valve Boxes. Valve boxes and covers shall be cast iron of a type approved by the Engineer prior to their installation. The lengths shall be suitable for the particular depth of water line. Valve Marker Posts. A concrete valve marker post shall be furnished and installed as directed, with each gate valve. The concrete marker post shall have a 4" minimum square section and a minimum length of 42", with beveled edges and containing at least one (1) 3/8" diameter bar of reinforcing steel. Markers shall be placed as directed by the Engineer and set so as to leave 18" exposed above grade. The exposed portion of the marker posts shall be painted with two (2) coats of white concrete paint, and then the size of the valve (for example, 6" G.V.) and the distance in feet and inches to the valve shall be stenciled with black paint on the face of the post, using a stencil which will produce letters two (2) inches high. Auxiliary Valves. Auxiliary gate valves shall be flanged or as required by the type of pipe being used, and be as specified in Paragraph E. Fire Hydrant Guard Posts. Concrete fire hydrant guard posts shall be furnished and installed with fire hydrants as directed by the Engineer. The guard posts shall be made of reinforced concrete, eight (8) inches in diameter, six (6) feet long, and buried to a minimum depth of three (3) feet. Guard posts shall not be set higher than the top of the fire hydrants, they shall be plumb, and where two posts are used at a hydrant, they shall be set with their tops at the same elevation. The exposed portion of the guard posts shall be painted with two (2) coats of white concrete paint, approved by the Engineer. Cover Over Pipelines. In no case shall less than thirty-six (36) inches of cover be maintained over the pipe. Local variations in ground surface shall not control, but the average depth shall be the determining factor. The maximum depth shall not be greater than 60" to the top of the pipe. - 7 - Hydrostatic Test. All new water main installations shall be subjected to a hydrostatic pressure test of 180 PSI for 30 minutes in duration at the high point in the line. For approval, the pressure shall not drop more than 10 PSI or to 170 PSI within the test period. All air shall have been cleared from the line prior to starting the test. After testing the total installation, each section of the main between valves shall also be tested to insure valve inte- grity. Insofar as is practical, the test shall be made with all pipe joints, fitting, and valves exposed. Also, all pipe joints and angles except for final coupling shall also be installed and subjected to the test pressure. If services are altered or relocated after completion of hydrostatic testing, the test must be repeated to insure the integrity of the system. Prior to calling out the Engineer to witness the pressure test, the Developer shall have all equip- ment completely ready for operation and shall have successfully performed the test to assure himself that the pipe is in a satisfactory condition. Sterilization. Before placing the lines in service, the Developer shall sterilize them and have a satis- factory report and approval of sterilization from the local or state health department on samples collected from representative points in the new system. Sterilized sample bottles and/or instruc- tions shall be obtained by the Developer from the laboratory where the samples will be tested. The Developer shall collect all samples for the bac- teriological tests under the direct supervision of the Public Works Department. Fire hydrants installed in unpaved areas shall have a 4 inch thick, 3 foot square concrete pad poured around them. 13.10,110 STREET GRADE AND HYDRANT CLEARANCE. Hydrants shall stand plumb, be set to established street grade with the lowest outlet of the hydrant no less than eighteen inches (18") above the street grade nor more than twenty-eight inches (28") above grade and no less than thirty-six inches (36") of clear area about the hydrant for clearance of hydrant wrench on both outlets and on the control valve. The pumper port shall face the street. Where the street cannot be clearly defined or recognized the port shall face the most likely route of approach and location of the fire truck while pumping as determined by the City Engineer. 13.10.120 SURROUNDING VEGETATION PROHIBITED. No person shall plant any vegetation, erect any structure or perform any action which results in the obstruction of a fire hydrant for a distance of 50 feet along the imme- diate route of approach. The owner-occupant of any area in which a hydrant is located shall be responsible for removing weed and tree growth from around the hydrant for a distance of not less than five feet. The purpose of this section is to maintain clear approach and visual area around the hydrant. 13.10.130 OCCUPANCY OF BUILDING. No building or struc- ture shall be occupied or used prior to installation and approval of required hydrants and mains as set forth in this chapter. 13.10.140 UNLAWFUL CONDUCT. It is unlawful for any person, firm or corporation to occupy or use any build- ing used for a school, church, rest home, hospital, - 8 - residential apartments or place of assembly, in whatever use district located, unless such building is within one hundred fifty feet (150') of a fire hydrant. 13.10,150 INSPECTION REQUIRED. All improvements shall be subject to inspection by a duly authorized represen- tative of the City, both during the course of construc- tion and after construction is complete. The inspector shall have the authority to determine whether or not materials of construction, methods of construction and workmanship comply with working drawings and specifica- tions. The contractor shall provide for reasonable tests and proof of quality of materials as requested by the inspector. The inspector may require that work be suspended for due cause. For purposes of this section, "due cause" includes adverse weather conditions, poor workmanship, the use of questionable materials or methods of construction, and nonadherence to specifica- tions and drawings. 13.10,160 APPROVAL NOT DEEMED ACCEPTANCE. Approval by the inspector shall not be deemed acceptance of the improvement by the City. Acceptance shall be only by action of the Winslow City Council. 13.10.170 PENALTIES. Any person violating any provi- sion or term of this chapter shall, upon conviction thereof, be punished by a fine of not more than $500.00 or by imprisonment for not more than ninety (90) days, or be both such fine and imprisonment. Section 2. If any section, sentence, clause or phrase of this ordinance should be held to be invalid or unconstitutional by a court of competent jurisdiction, such invalidity or uncon- stitutionality shall not affect the validity or constitutionality of any other section, sentence, clause or phrase of this ordinance.
