WATER SYSTEM INFORMATION 1. ❑ Water service can be provided by service connection to an existing " diameter water main that is approximately feet from the site. 2. ® Water service for the site will require an improvement to LWSD's water distribution system of: ® a. 5+/- feet of 8" & 12" 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. Upsizing of existing water mains <8" diameter will likely be 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. S. Water service is subject to: ® a. Payment of connection charges (to be determined by LWSD); ® b. Proof or reservation of easement(s) as required by LWSD; ® c. Other: LWSD DE Agreement (#2 above) must be accepted by LWSD, prior to service connection activation(s). Comments/special conditions: The nearest fire hydrant will be on the Property (number & location TBD by fire marshal). Fire Flow at no less than 20 psi available within the water distribution system is a minimum 2.500 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. 537 Pressure Zone Est.

Model results depict the theoretical performance of the water system under high demand conditions and are not guaranteed to represent actual system performance. A design professional should be consulted for site specific design purposes. The calculated fire flow capacity in the above table is based on a currently available residual system pressure of 20 psi at the location modeled. The model indicates that Lakehaven's standard maximum allowable velocity of 10 ft/s is exceeded at a fire flow rate above 1600 gpm. Fire flow capacities greater than 1600 gpm may be accommodated through water system improvements. 052819FF 360 - 3 3 0 0 5 15th AV2 S (Form Update 1/6!17) Requested By: Date: DaNkm Zern 5/22/19 Location to be Modeled: Existing Hydrant near Parcel # 1721049046 Results By: John Bowmall;: Lakehaven'/a Section Grid: J/10 intersection: S 330th St & 15th Ave S Add.
