6) calculating an equivalent unit for the developer at 400 gpd, rather than the 600 gpd per unit that developers mistakenly thought they were allowed as an average use in the past. The Deputy said that both sides agreed that the equivalent units should be clarified within the Agreement. Ms. Lee Loy asked about the reference to "No Practical Alternatives," on the first page, under letter D. She wanted clarification on what "practical alternatives" meant. Mr. Kawahara gave some background of the property in question. Prior to Kamakoa Partners' purchase of the property, Mr. Kawahara's firm was the engineer for the previous owner. His firm looked at various alternatives for getting water, which proved to be very challenging. The previous owner decided not to pursue development, and Mr. Kawahara's firm got to know Kamakoa Partners when they purchased the property. The previous owner had drilled an exploratory well on the mauka side of the parcel, he said, as he distributed copies of a map showing the area. Sampling of the exploratory well came up with brackish water, and desalination would have been unfeasible. Mr. Kawahara's firm looked at other options, such as tapping into the private water system mauka of the property, in Waikoloa, but there was no storage tank to provide fire protection that is required by County code. After looking at various alternative methods and means, the best solution for providing potable water to the property in question was DWS's Lalamilo water system with its various reservoirs providing 3 million gallons of storage at the 610 -foot level. He noted that the exploratory well with its brackish water will be used for irrigation, and the developer is considering using recycled water for irrigation as well. Mr. Uyeda asked if Well A, with its increased capacity, would burden the other wells. Mr. Inaba said that there would be minimal impact, since the tie-in from Well A to the system is a very short distance. The Deputy said that it would be part of the hydraulic calculations on the design portion of the project; DWS will have the design consultant look at that.
