M Honoka'a Plantation Cottages Traffic Assessment Report May 22, 2020 B. Conclusions Lehua Street is a curvilinear roadway, both vertically and horizontally,along the project frontages. The development of the proposed Honoka'a Plantation Cottages is expected to improve sight distances along its frontages by removing the existing vegetation and roadside embankments that obscure the lines of sight, as necessary. The project access driveway and subdivision roadway intersections on Lehua Street should be situated and designed so as to provide appropriate sight distances on all approaches to the proposed access points. In the future, the existing one-lane drainage crossing on Lehua Street may require widening to two lanes with the increase of two-way traffic on Lehua Street. Pakalana Street operated at LOS "C" at Mamalahoa Highway, during the existing AM and PM peak hours of traffic. Pakalana Street is expected to continue to operate at LOS "C"at Mamalahoa Highway through the Year 2024 without and with the proposed project. Lehua Street is expected to operate at LOS "B" and LOS "A" at Pakalana Street, during the Year 2024 AM and PM peak hours of traffic, respectively, without and with the proposed project. Per the Hawaii County Code"Concurrency Requirements",LOS's"A", "B" and "C" are considered to be acceptable Levels of Service. As such, the proposed Honoka'a Plantation Cottages project is not expected to significantly impact the intersections in the study area. Therefore, traffic mitigation is not recommended at the intersection of Mamalahoa Highway and Pakalana Street at this time. • 16
