This signal does not operate in <br />Alvarado Street (#28) to reduce from LOS D to LOS E in coordination with any other signal; therefore, the cycle length can <br />the PM peak hour under Near -Term Cumulative be adjusted without affecting other signals in the system. <br />Conditions. <br />TRAF-7E: The proposed Project would cause the level of <br />S TRAF-7E: Implementation of Mitigation Measure TRAF-1C, installing LTS <br />service at the intersection of Aurora Drive and Marina <br />a mini -roundabout or a traffic signal, would lessen the near term <br />Boulevard (#10) to reduce from LOS A to LOS F in the AM <br />cumulative impacts to less than significant. The mini -roundabout <br />peak hour and from LOS B to LOS F in the PM peak hour <br />would improve the operations to LOS A in all three peak period <br />and from LOS B to LOS E in the Saturday peak hour. <br />hours. A traffic signal would improve the operation of the <br />intersection to LOS B in the AM peak hour and LOS A in the PM and <br />Saturday peak hours. <br />TRAF-7F: The proposed Project would cause the level of <br />S TRAF-7F: Implement Mitigation Measure TRAF-1D by installing a LTS <br />service at the intersection of Monarch Bay Drive and <br />roundabout. This would improve the operations to LOS A in the PM <br />Mulford Point Drive (#19) to reduce from LOS A to LOS F <br />peak hour. <br />in the PM peak hour. <br />TRAF-7G: The proposed Project would cause the <br />S TRAF-7G: Implement Mitigation Measures TRAF-1A.1 and TRAF-1A.2.
