City of Santa Ana -Park View at Town and Country Manor <br />Draft EIR <br />Opening Year (2013) - Traffic Increase and Level of Service Standards <br />and Traffic <br />Impact 4.6 -1 The project would cause an increase in traffic, which is substantial in relation to the <br />existing traffic load and capacity of the street system (i.e., result in a substantial <br />increase in either the number of vehicle trips, the volume to capacity ratio on roads, <br />or congestion at intersections). <br />The project would exceed, either individually or cumulatively, a level of service <br />standard established by the county congestion management agency for designated <br />roads or highways. <br />[CEQA Transportation and Traffic Thresholds 15(a) and 15(b)] <br />Impact Analysis <br />Opening Year (2013) Traffic Conditions Without the Project <br />Opening Year (2013) Without Project traffic volumes for study area roadway segments and <br />intersections are presented in Table 4.6 -9and Table 4.6 -10, respectively. All future year analyses <br />assume the signalization of the intersection of Lawson Way at Memory Lane. With the addition <br />of ambient growth and cumulative projects traffic, Main Street between La Veta Avenue and <br />Town & Country Road is anticipated to operate at an unacceptable LOS F, and Parker Street <br />between La Veta Avenue and Town & Country Road is anticipated to operate at an unacceptable <br />LOS E. (Cumulative projects, defined as projects that have already been approved, or are pending <br />and likely to be approved, are detailed in Section 3, Project Description, and on Exhibit 3 -6.) <br />Roadway improvements to address these deficiencies are discussed in project mitigation later in <br />this analysis. <br />All study intersections will continue to operate at an acceptable LOS D or better in both peak hours, <br />except the intersection of Main Street/1-5 SB Off -Ramp at Santa Clara Avenue /I -5 NB On -Ramp <br />which is anticipated to operate at an unacceptable LOS E. <br />Table 4.6 -10: Summary of Daily Roadway Operation - Opening Year (2013) Without Project <br />Roadway Segment <br />Type of <br />Lane <br />LOS E <br />Future <br />V /C' <br />LOS <br />Arterial <br />Config. <br />Capacity <br />ADT <br />La Veta Avenue <br />Major <br />6 -lane <br />56,300 <br />32,188 <br />0.572 <br />A <br />- Main Street and the SR -22 WB ramps <br />divided <br />La Veta Avenue <br />Primary <br />4 -lane <br />37,500 <br />20,181 <br />0.538 <br />A <br />- SR 22 WB ramps and Glassell Street <br />divided <br />Town & Country Road <br />Primary <br />4 -lane <br />37,500 <br />19,869 <br />0.530 <br />A <br />- Main Street and the SR -22 EB ramps <br />divided <br />Town & Country Road <br />Primary <br />4 -lane <br />37,500 <br />8.476 <br />0.226 <br />A <br />- SR-22 EB ramps and Memory Lane <br />divided <br />Memory Lane <br />Major <br />6 -lane <br />56,300 <br />11,321 <br />0.201 <br />A <br />- Main Street and Lawson Way <br />divided <br />Memory Lane <br />Collec- <br />4 -lane <br />37,500 <br />5,098 <br />0.136 <br />i <br />- Lawson Way and Town & Country <br />for <br />divided <br />Road <br />Michael Brandman Associates 4.6 -15 <br />H\Cl t(PN- Rnb327b32]003MMVB2]0030 Sec0 Trayspo .d¢ <br />
