WATER SYSTEM INFORMATION
1. ® Water service can be provided by service connection to an existing 16" diameter water main that is approximately 20+/-
feet from the site.
2. ® If new/onsite fire hydrant required, water service for the site will require an improvement to LWSD's water distribution
system of:
® a. 2 + - feet of 6" diameter fire hydrant lateral 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) or Facilities Installation (FI) Agreement required.
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
Boundary Review Board approval for extension of water service outside of LWSD's water service area.
❑ b. Annexation or Boundary Review Board approval will be necessary to provide service.

® c. Other: LWSD Service Connection application required. subject to completion of associated LWSD DE or FI
Agreement oroiect.
Comments/special conditions:
The nearest fire hydrant is approximately 70+/- feet from the Property (as marked on map on the back of this page).
System hydraulic model results (FF #442, 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 5,100 GPM. 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.
578 Pressure Zone Est. Meter Elevation (s)-GIS: 459+/- Est. Pressure Range at Meter(s) (psi): 48-57
I hereby certify that the above water system information is true. This certification shall be valid for one (1) year from the date of
signature.
