Grand Avenue Widening Project Environmental Impact Report Section 3.0 <br />TABLE 3.5-4 <br />LEVEL OF SERVICE CRITERIA FOR SIGNALIZED INTERSECTIONS <br />LOS <br />Description <br />ICU <br />A <br />Very low delay. Most vehicles do not stop at the intersection. <br />0.00 to 0.60 <br />B <br />More vehicles stop than with LOS A, causing higher delays. <br />0.61 to 0.70 <br />C <br />The number of vehicles stopping becomes significant, though many <br />0.71 to 0.80 <br />still pass through the intersection without stopping. <br />D <br />The influence of congestion becomes more noticeable. Many vehicles <br />0.81 to 0.90 <br />stop and the proportion of vehicles not stopping declines. <br />E <br />Results in delay considered to be unacceptable. <br />0.91 to 1.00 <br />F <br />Considered unacceptable to most drivers, often occurs with <br />Above 1.00 <br />oversaturation, when arriving traffic exceeds the capacity at the <br />intersection. <br />Source: City of Santa Ana, General Plan - Circulation Element (1998). <br />Methodology Related to On Street Parking <br />The availability of on street parking and City policy regarding on street parking on arterials were <br />reviewed. Impacts on off street parking were considered earlier in Section 3.2 (Land Use and <br />Planning) related to the acquisition of property for the proposed widening of Grand Avenue. <br />Specifically, during the land acquisition process, the City will assess whether the removal of off <br />street parking from individual parcels and land uses results in non -conforming uses. Mitigation <br />is provided in Section 3.2 (Land Use and Planning) related to the acquisition of right-of-way, <br />including parcels which become non -conforming as a result of the removal of off street parking. <br />Methodology Related to SCAG Transportation Policies <br />SCAG identified a number of transportation policies in the growth management chapter of the <br />Regional Comprehensive Plan and Guide and in the Mobility Element. The proposed Grand <br />Avenue widening alternatives were evaluated for consistency with these transportation policies. <br />3.5.4 IMPACTS RELATED TO TRANSPORTATION <br />Future year traffic forecasts were developed using a citywide computerized travel demand <br />forecasting model. Future total daily traffic volumes and AM and PM peak hour intersection <br />turning movements were provided by the City of Santa Ana for use in this analysis. These forecasts <br />assume completion of transportation improvements in the City's seven year Capital Improvement <br />Program and other improvements in Orange County which are ongoing or programmed for <br />implementation by 2020. <br />F.IPROJ-ENPIGrand eirWew Text- GrandlSection 3 SplitlSection 3.5.doc Page 3.5-9 <br />
