1 1 Level of Service ICU Value Description Poor operation. Some long-standing vehicular queues develop on E 0.91-1.00 critical approaches to intersections. Delays may be up to several minutes. Force flow. Represents jammed conditions. Back-ups from locations F Over 1.00 downstream or on cross street may restrict or prevent movement of vehicles out of the intersection a roach lanes.

Table 12 shows the expected traffic LOS for year 2008, the project-opening year, without the proposed project. This forecasted growth includes a compounded 1% per year growth rate (2% total for this calculation) and the addition of any related projects in the vicinity of the proposed project, but not the proposed project itself.

Febru 2007. As can be seen from the previous tables, the future Year 2008 traffic will slightly degrade at both intersections from LOS (C) to LOS (D), with the exception of the Harbor Boulevard/First Street intersection, where the AM peak hour LOS will continue unchanged at LOS (D). Since the intersections have not degraded to LOS (E) or (F), the change is considered acceptable under the requirements of the City of Santa Ana. Table 13 depicts the forecasted, Year 2008, traffic levels with and without the proposed project. As can be seen from the table, the LOS with the addition of the project does not significantly degrade the level of service. The ICU at the study intersections decreases less than 1% except for the Harbor Boulevard/First Street PM peak, which decreases by 3%. This is still within the less than significant impact criteria as defined by the City of Santa Ana.
