Honorable James Y. Arakaki, Chairman <br />and Members of the County Council <br />Page 5 <br />driveways with Mamalahoa Highway and Konawaena School Road were found to <br />operate at acceptable conditions during both peak hours. The project site driveways will <br />be designed to provide adequate sight distances for proper execution of turning <br />movements into and out of the project site." <br />The Department of Public Works is recommending that that the project's <br />Mamalahoa Highway driveway be restricted to right -turns -in and right -turn -out only due <br />to potential conflicts of vehicles attempting left turns into and out of the project site. A <br />left turn lane into the project's Konawaena School Road access driveway is also <br />recommended. Pavement widening and transitions with concrete curb, gutter, sidewalk, <br />drainage improvements and possible relocation of utilities, which are improvements <br />typical of Commercial -zoned properties, are likewise recommended along the project <br />site's frontages with both the Mamalahoa Highway and Konawaena School Road. The <br />recommendations of the Department of Public Works will be incorporated as a condition <br />of this favorable recommendation. We should note that the Department of Public Works <br />did object to the use of existing commuter traffic patterns within the TIAR and its focus <br />on traffic generated specifically by the proposed visitors' center complex. The Planning <br />Director has determined that the roadway and traffic circulation improvements being <br />required by this favorable recommendation will result in the proposed visitors' center <br />having no significant adverse impacts upon traffic. However, the applicant's request is <br />for a change of zone to a Village Commercial (CV -10) zoned district that may allow for <br />automobile service stations, apartment complexes, retail establishments and other uses <br />that may generate much higher traffic volumes to and from the project site should these <br />uses be established and which the TIAR failed to consider. The Planning Director is <br />therefore recommending that should any use beyond the proposed visitors' center <br />complex by contemplated by the applicant, a revised TIAR and the construction of <br />appropriate traffic mitigating improvements will be required prior to the establishment of <br />such use. <br />According to the applicant, the project site is currently being serviced with three <br />(3) water service laterals within 5/8 -inch water meters installed within two of the laterals. <br />The two metered laterals are located along the Mamalahoa Highway. Anticipating <br />approximately 90 visitors a day to the proposed complex and 12 employees over the <br />course of a 16 -hour day, the applicant has calculated a conservative water demand <br />estimate of 28,800 gallons per day (gpd). The applicant anticipates that a3/4 -inch water <br />meter must be installed within the last un -metered water lateral located along Konawaena <br />School Road to provide adequate water service to the proposed visitors' center complex. <br />The Department of Water Supply has informed the Planning Director that only 4,200 gpd <br />has been allocated through the 3 water service laterals available to the project site, or only <br />14.5 percent of the total water demand anticipated by the proposed visitors' center.
