' ~ PAHOA COMPLEX OFFSITE IMPROVEMENTS TRAFFIC IMPACT ANALYSIS REPORT ( seconds in the morning peak with queue length increasing from 10 to 12 vehicles. In the afternoon peak, delay is calculated to increase from 81 to 124 seconds with queue length increasing from 8 to 10 vehicles. In comparison, the additional traffic generated by the proposed project would have very little impact on this movement. The morning I delay would increase from 180 to 188 seconds with no increase in queue length. The afternoon delay would increase from 124 to 130 seconds and queue length from 10 to 11 vehicles. The increase in ambient traffic and project generated traffic would not have any adverse impact upon the other two movements at this intersection. I The additional traffic from the ambient traffic forecasts would change the level of service I for the outbound left turn movement at Kahakai Boulevard from E to F in both peak periods, indicating an adverse impact. Morning peak delay is calculated to increase I from the current 45 to 54 seconds with queue length increasing from 4 to 5 vehicles. Afternoon peak delay is calculated to increase from the current 47 to 57 seconds with I queue length increasing from 2 to 3 vehicles. The additional traffic generated by the proposed project would have very little impact on this movement. The morning delay I would increase from 54 to 56 seconds with no change in queue length. The afternoon delay would increase from 57 to 60 seconds with no change in queue length. The increase in ambient traffic and project generated traffic would not have any adverse impact upon the other two movements at this intersection. I The project access roadway approach would exist only for the total with project forecast. I The outbound right turn movement is forecast to operate at level of service B and the outbound left turn movement at level D in both peak periods. The left tum movement I from Highway 130 into the project access road is forecast to operate at level of service Ain both peak periods. These are acceptable levels of service and do not indicate the I need for mitigating measures. A storage length for two vehicles would be sufficient for the left turn lane on Highway 130. The above analysis indicates that the Old Keaau-Pahoa Road intersection is currently in need of measures to mitigate undesirable traffic operations. The Kahakai Boulevard intersection would require mitigation in the next several years due to increases in M & E PACIFIC, INC. PAGE 9 60018945.00300 December 2006 Pahoa Complex TIAR.doc
