WATER SYSTEM INFORMATION
1. ® Water service can be provided by service connection to an existing 8" diameter water main that is approximately 5-95
feet from the lots/parcels.
2. ❑ Water service for the site will require an improvement to LWSD's water distribution system of:
❑ a. feet of " 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):
3. ® a. The existing water system is in conformance with LWSD's Comprehensive Water System Plan.
❑ b. The existing water system is not in conformance with LWSD's Comprehensive Water System Plan and an
Amendment to this Plan will be required. This may cause a delay in issuance of land use approvals or permits.
4. ® a. The subject property is within the corporate limits of Lakehaven Water & Sewer District, or has been granted

Service Connection Application reauired, for any new/modified service connection(s).
Comments/special conditions: Service pressure(s) greater than 80 psi indicated, Pressure Reducing Valve(s) indicated, contact local
building official for reauirements &/or additional information.
The nearest fire hydrant is approximately 35-120 (+/-) feet from the Property (as marked on map on the back of this page).
System hydraulic model results (FF #283, copy attached), at no less than 20 psi, indicate that LWSD's standard maximum allowable
liquid velocity of 10 ft/s is exceeded at a fire flow rate above 3,100 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: 324+/- Est. Pressure Range at Meter(s) (psi): 84-92
I hereby certify that the above water system information is true. This certification shall be valid for one (1) year from the date of
