conditions, develop trip generation characteristics, analyze traffic impact on Mamalahoa Highway from two proposed access driveways, Ishihara Farm Road and at adjacent intersections in the project area (Waikelehua Place, Keaka Kea Place and Earl's Pa`auilo Store Driveway) and to recommend ways to mitigate impacts identified in the study. Based on the findings, the TIAR recommends the following traffic mitigation measures: 1) The median taper on the left-turn lane on eastbound Mamalahoa Highway at Keaka Kea Place should be restriped to extend the two-way, left-turn lane from Earl's Pa`auilo Store Driveway to the beginning of the left-turn lane at Keaka Kea Place; 2) Minimum 100-foot spacings should be provided between the intersections on Mamalahoa Highway at Waikelehua Place, the west and center driveways, and Earl's Pa`auilo Store Driveway/Ishihara Farm Road; 3) The site frontage road should be set back a minimum of 25 feet from the future right-of-way of Mamalahoa Highway; and 4) The west and/or the center driveway should be designed to accommodate the truck turning movements to/from Mamalahoa Highway. According to correspondence from the applicant and the State Department of Transportation (HDOT), there are several issues that need to be addressed in an updated TIAR including, but not limited to, providing acceptable rationale for two commercial driveways from Mamalahoa Highway instead of a single consolidated access from the existing Ishihara Farm Road, current easement restrictions on the property, and justifying the proposal of a two-way, left-turn lane on Mamalahoa Highway. As access from the highway is under the jurisdiction of the State, a condition of approval will be added requiring the applicant to furnish an updated TIAR to HDOT for approval,prior to issuance of final plan approval for any use in the CN-zoned area, since the proposed commercial development will have the most impact on traffic conditions. Mamalahoa Highway is designated by the General Plan as a secondary arterial road and thus shall be improved to the required standard with an 80-foot right-of-way, which will require the applicant to continue to provide a 10-foot-wide future road widening setback along the property's entire Mamalahoa Highway frontage. As a result of Subdivision No. 7820, approved by the Planning Department in 2004, the subject property currently has a 10-foot-wide "No Vehicular Access & Planting Screen" -6-
