liquid velocity of 10 ft/s is exceeded at a fire flow rate above 2,800 GPM for two (2) hours or more. This flow figure depicts the
theoretical performance of the water distribution system under high demand conditions. Fire flow rates greater than this may be
accommodated through water distribution system improvements, contact LWSD for additional information.
