REQUEST: RS-10 TO RCX-20 TAX MAP KEY 2-2-038:028 We have reviewed the subject application and have the following comments and conditions. There is an existing 10_inch waterline withinKilauea Avenue fronting the subject parcel. The subject parcel is currently served by a 5/8-inch meter,which is limited to an average daily usage of 400 gallons. The Department has no objection to the proposed change of zone application subject to the applicant understanding and accepting the following conditions: 1. Prior to effecting a water commitment for the subject application,the applicant must submit estimated, maximum daily water usage calculations, prepared by a professional engineer licensed in the State of Hawai`i, for review and approval. The water usage calculations should include the total estimated maximum daily water usage(in gallons per day)and the estimated peak flow(in gallons per minute). Based on the water usage calculations provided,if the existing 5/8-inch meter cannot accommodate the estimated demand, a larger or additional meter will need to be installed and remittance of the prevailing facilities charge, which is subject to change, will be required. If a 5/8-inch meter can accommodate the estimated demand,then the applicant may continue to utilize the 5/8-inch meter. 2. The proposed land use will require the installation of a reduced pressure type backflow prevention assembly,within five(5)feet of the meter on private property. If a larger or additional meter is required,a backflow prevention assembly will also be required for that meter. The installation of the backflow prevention assembly(s)must be inspected and approved by the Department before water service can be activated. 3. Subject to other agencies' requirements to construct improvements within the road right-of-way fronting the property affected by the proposed development,the applicant shall be responsible for the relocation and adjustment of the Department's affected water system facilities, should they be necessary. 4. Please be informed that the existing 10-inch waterline within Kilauea Avenue is adequate to provide 2,000 gallons per minute of flow for fire protection,as required per the Department's Water System Standards for the proposed type of land use.
