Percent change in delay is 0.2 percent. The intersection <br />of Town & Country Road and the SR -22 Eastbound (EB) Ramps will also continue to operate at <br />LOS E or LOS F in the morning and evening peak hours. This project - related impact is significant at <br />the Caltrans- controlled intersection of Town & Country Road/SR -22 EB Ramps because the increase <br />in delay is more than one percent. (A significant impact at Caltrans intersections is identified when <br />project - related traffic causes the intersection to operate at an unacceptable level of service and <br />increases the delay by greater than one per cent.) The delay at this intersection would be impacted by <br />the project by 2.6 percent in the morning peak hour and by 1.7 percent in evening peak hour. <br />Michael Brandman Associates 4.6 -31 <br />H\Cl t(PN- JMb327b327003MMVB270030 Sec0 Tmspo md¢ <br />
