Lakehaven Water & Sewer District, at its sole discretion, reserves the right to delay, or deny, water service based upon capacity &/or supply limitations in Lakehaven’s or Other Purveyor’s system facilities. Proposed Land Use: Building Permit-SFR () Building Permit-MFR (73 units) Building Permit-Other (2) Subdivision () Short Subdivision () Binding Site Plan Boundary Line Adjustment Other (specify/describe) Tax Parcel Number(s): 7204800188, 7204800190 Site Address: 27614 Pacific Hwy S LWSD GIS Grid: K-03 Ex. Bldg. Area to Remain: N/A sf New Bldg. Area Proposed: Food Bank 6,000 sf, Office 3,000 sf WATER SYSTEM INFORMATION 1. Water service can be provided by service connection to an existing 8” diameter water main that is approximately 20+/- feet from the site. 2. If additional/new/relocated fire hydrant(s) required, water service for the site will require an improvement to LWSD’s water distribution system of: a. 20+/- 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. 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. 5. Water service is subject to: a. Payment of connection charges (to be determined by LWSD, for any new/modified service connection); b. Proof or reservation of easement(s) as required by LWSD (if applicable); c. Other: The existing meters need to be evaluated under UPC & LWSD standards, to determine if they’ll be adequate for the proposed uses. LWSD Service Connection application(s) required, for any new/modified service connection. If applicable, LWSD DE Agreement (#2 above) project must be accepted by LWSD, prior to service connection activation. Additional/new offsite LWSD water easement (north of site) required, for any new main extension &/or service installations to existing 8” offsite water main. Comments/special conditions: Service pressure(s) greater than 80 psi indicated, Pressure Reducing Valve(s) indicated, contact local building official for requirements &/or additional information. The nearest fire hydrants are approximately 20-35 (+/-) feet from the Property (as marked on map on the back of this page). System hydraulic model results (FF #179, 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 1,400 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. 578 Pressure Zone Est. Meter Elevation(s)-GIS: 328+/- Est. Pressure Range at Meter(s) (psi): 105-114 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.
