System hydraulic model results (FF #227), at no less than 20 psi, indicate that Lakehaven's standard maximum allowable liquid
velocity of 10 ft/s is exceeded at a fire flow rate above 5.200 GPM (approximate). 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 Lakehaven for additional information.
