10.10.060 Location. (A) All public fire hydrants shall
be installed at street intersections where possible. Public
hydrant spacing shall be measured along vehicular access routes.
(B) In single family residential areas public hydrants
shall be spaced so that the maximum distance between them is
six hundred feet. If street intersections are over seven hundred
feet apart, additional public hydrants will be placed between
them so as not to be more than six hundred feet from public
hydrants on either side. If cul-de-sacs or dead-end streets,
road or driveways, or -combinations thereof, are over t_br€e
hundred feet long, additional public hydrants shall be installed
sit public hydrant spacing is not over six hundred feet.
(C) In areas other than single family residential, public
fire hydrants shall be instaII—ed-so-that the distance etween
them averages three hundred feet. If street intersections are
over four hundred feet apart, additional public fire hydrants
shall be.placed between them so as not to be more than three,
hundred feet apart. If cul-de-sacs or deed -end streets, roads
or driveways, or combinations thereof,.are over one hundred
fifty feet long, additional public hydrants shall be installed
so that the public hydrant spacing is not over three hundred feet.
(D) For the purpose of this chapter, the fire flow require-
ment for areas other than single family residential shall be de-
termined by the fire chief, whose determination will be based on
the criteria set forth in Appendix "A," a copy of which is on
file in the office of the city clerk and by this reference is in-
corporated herein as if set forth in full, and such other factors
as require adequate fire flow.
(E) The required fire flow shall be available at aresidual
pressure in the mains figured for ground elevation of not.less
than twenty PSI, except where the building is equipped with fire
protection systems dependent upon the distribution mains for sup-
ply, in which case the required fire flow shall be available at
a residual pressure which will satisfactorily operate the afore
mentioned system'.
(F) All buiidiri a r cent s id A, family, are
located so that'a portion is, more "than two hundred feet -from —,a
stream," as measured along. the right-of-way nI� of .vehicular °ac
cess routes, shall have private fire hydrants located at the
building.
(G) Buildings having required fire flows of less than
two thousand five hundred GPM's may 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 five thou-
sand square feet in first floor area including covered parking
and storage. When the required fire flow is over two thousand
five hundred GPM, the fire hydrants shall be served by a loop
main around the building or complex of buildings.
(H) The number of fire hydrants'to be installed shall be
determined by having an average spacing three hundred feet
measured aro�'� the perimeter five hundr:,_ feet out from the
buildings. All hydrants are to be accessible to fire department
vehicles over all-weather roads. The fire .chief shall determine
the location of fire hydrants depending on utility, topography
and building location for maximum fire protection purposes. (Ord.
