• A significant project impact occurs when the ICU value increases by greater than .01 and achieves unacceptable level of service (E or F) or worse Table 8 illustrates a comparison of study intersections under Opening Year (2013) conditions. As shown, the proposed project will not generate a significant impact to the intersections within the study area.

The study found that the proposed project would have no significant impact at any study intersections. No new mitigation measures are required and the previous analysis in the FEIR remains adequate and complete in the area of traffic impacts. MacArthur Place South EIR - 2011 Addendum 42 75B-87
