As shown in Table E, <br />the intersections along Fairview Street are anticipated to operate at acceptable LOS with the <br />exception of the following intersections: <br />• Fairview Street/17th Street (LOS F during both the a.m. and the p.m. peak hours) <br />• Fairview Street/16th Street (LOS F during the a.m. peak hour and LOS E during the p.m. peak <br />hour) <br />• Fairview Street/91h Street (LOS F during both the a.m. and the p.m. peak hours) <br />• Fairview Street/Civic Center Drive (LOS E during the a.m. peak hour) <br />Like the analysis results for 2021 Build condition, several of the study intersections are shown to <br />operate at higher levels of delay or capacity under 2040 Build condition, compared to the 2040 No <br />Build condition, because of the rerouting of regional north -south vehicular traffic from parallel <br />routes that may now use Fairview Street due to the proposed improvements. Exceptions include the <br />intersections of Fairview Street at 171h Street and 121h Street, which operate better due to <br />reductions in travel patterns (higher north -south through traffic while lower east -west turning <br />movements at 17th Street) and changes in access (121h Street). <br />PAWKE1702\Traffic\doc\Traffic Analysis Report rev - Caltrans Comments.docx u06/07/18» 16 <br />
