PUBLIC SERVICES AND FACILITIES 23. Access/Traffic: Access to the permit area is from Mamalahoa Highway, a two-lane arterial State roadway with approximately 30-foot-wide pavement within a 70-foot-wide right-of-way. There are two driveways that connect the permit area to the highway, with the southernmost driveway solely dedicated to inbound traffic. Middle Ke`ei Road, a private two-lane road, is the nearest road that intersects the Highway, approximately 0.1 miles north of the permit area. There are no pedestrian or bicycle facilities near the permit area. The highway fronting the permit area has a small,paved shoulder but this is not intended for pedestrian use. The County Mass Transit agency has a bus stop 0.4 miles north of the permit area at Ho`olala Road. A traffic analysis (mobility analysis report) was performed and found that the additional traffic generated by the project will not create an unacceptable level of service at the intersection of Mamalahoa Highway and Middle Ke`ei Road during morning and afternoon peak hours. With the project, the PM peak hour level of service (LOS)would remain the same (LOS C) and the AM peak hour level of service would degrade slightly from LOS B to LOS C. In both cases, the LOS is acceptable to County concurrency standards for traffic. The applicant also proposed the following traffic modifications to be made on-site outside of the highway right-of-way to improve circulation and safety: ■ Widen current driveway to a minimum of 20 feet to accommodate two-way traffic; ■ Install two stop signs, one at a location near the Highway and one between the two-lane driveway and the parking in front of the existing building; ■ Remove parking stalls along the parcel 038 highway frontage and add 12 overflow parking stalls along the south side of the permit area (on parcel 014); ■ Stagger drop-off and pick-up times to keep traffic circulating; and ■ Allow for the future planned widening of Mamalahoa Highway to accommodate bicycle paths and improved pedestrian facilities. In a comment memo, the State Department of Transportation directed that the applicant implements the above-mentioned proposed access modifications and mitigation measures 6
