PUBLIC UTILITIES AND SERVICES 28. Vehicular Access/Traffic: Access to the subject property will be from a 24 -foot -wide, paved, private road named Hale Hana Street which runs through an adjacent parcel, TMK No. (3) 6-8-003:032, owned by the same landowner as the subject property, and intersects with Waik6loa Road, a county -owned and maintained roadway consisting of a pavement width of 60 feet at the location of the proposed access road, within a 120 -foot -wide right- of-way. Waik6loa Road is a major mauka — makai road, connecting Mamalahoa Highway and the Queen Ka`ahumanu Highway. The access road will be located directly across Waik6loa Road from Ehu Kai Loop and designed to form a new 4 -way intersection. Additionally, an emergency evacuation route from Hale Hana Street to Pua Melia Street will be provided. The application included a Transportation Impact Assessment Report (TIAR), dated September 2023, prepared by AECOM Technical Services, Inc. The TIAR analyzed the Waik6loa Road/ Ehu Kai Loop intersection, which was determined to operate at an existing LOS of between A and B. In estimating trip generation for AM and PM peak hours, the TIAR included a potential multi -family residential project that may be developed on an adjacent parcel, TMK (3) 6-8-003:032, which, if completed, could result in 329 multi -family dwelling units. Combined trips for the two projects (light industrial and multi -family) are estimated at a maximum of 109 AM peak hour and 115 PM peak hour trips. The TIAR concludes that even with additional traffic generated by the proposed light industrial uses, the Ehu Kai Loop / Hale Hana Street intersection is projected to operate at LOS D or better, an acceptable peak hour LOS, as an unsignalized intersection, in projections for 2028 peak hour intersection operations. Noting that the biggest traffic impact is at the Hale Hana Street left turning movements from Waik6loa Road, the TIAR points out that a complete warrant analysis to determine if signalization is warranted should be performed if there is consideration to implement a traffic signal at the intersection after completion of the proposed development and any other developments in the area. The TIAR further recommended several traffic mitigation measures for the proposed project, including: 1) Establish the Hale Hana Street approach as a stop sign control intersection with separate lanes for left turn movement and a shared through/right-turn approach; 2) Modify the median striping at the Waik6loa Road and I on
