2. Water service for the site will require an improvement to LWSD’s water distribution system of:
a. 5+/- feet of 8” diameter water main to reach the site; and/or
b. The construction of a water distribution system on the site; and/or
c. A major portion of LWSD’s comprehensive water system plan would need to be implemented and/or
constructed; and/or
d. Other (describe): LWSD Developer Extension (DE) Agreement required. Extend to far edge(s) per LWSD policy (if

Fire Flow at no less than 20 psi available within the water distribution system is a minimum 1,000 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.
538 Pressure Zone Est. Meter Elevation(s)-GIS: High 390+/-, Low 360+/- Est. Pressure Range at Meter(s) (psi): 55-77
