City of Santa Ana -Park View at Town and Country Manor and Traffic Draft EIR outside the MDA, the City's Level of Service standard is LOS D. A project is considered to have a significant impact at an intersection if the intersection level of service deteriorates to an unacceptable LOS F with the addition of project traffic. If a significant impact is identified, the project is required to mitigate the project's traffic - related impacts by incorporating mitigation measures to achieve an acceptable level of service. The City of Santa Ana does not have thresholds of significance for unsignalized intersections. City of Orange Impact Criteria The City of Orange has also adopted a target Level of Service "D" for intersections (ICU value of 0.90 or less). A project - related impact would be considered significant if the final V/C ratio exceeds 0.90, and the project contribution to the final V/C is greater than 0.010. If a significant impact is identified, the project is required to mitigate the project's traffic - related impacts by incorporating mitigation measures to reduce the impact to an acceptable level of service. Caltrans Impact Criteria A significant impact at Caltrans intersections is identified when project - related traffic causes the intersection to operate at an unacceptable level of service and increases the delay by greater than one per cent. Mitigation measures are required to bring the intersection back to pre - project (without project) conditions. Congestion Management Plan The Orange County Congestion Management Program (CMP) was established in 1991 to reduce traffic congestion and to provide a mechanism for coordinating land use and development decisions. Compliance with the CMP requirements ensures a city's eligibility to compete for State gas tax funds for local transportation projects. Within the defined CMP highway network, intersections are not allowed to deteriorate to a condition which is worse than LOS E or the base year LOS, if worse than "E," without mitigation being prescribed in an acceptable deficiency plan. Within the City of Santa Ana, the CMP Highway System includes three arterials: Harbor Boulevard, Edinger Avenue, and ls` Street. The project is located at the northeast corner of the intersection of Lawson Way and Memory Lane. There are no CMP intersection or roadway facilities within the study area. The Orange County CMP also states that "a TIA will be required for CMP purposes for all proposed developments generating 2,400 or more daily trips," and that "for developments which will directly access a CMP Highway System link, the threshold for requiring a TIA should be reduced to 1,600 or more trips per day." The project is estimated to generate a total of 887 daily trips. Given the forecasted number of daily trips and the lack of CMP intersections and roadway facilities within the study area, a separate CMP Traffic Impact Analysis is not required. 4.6.4 - Impact Analysis and Mitigation Measures This section discusses potential transportation and traffic impacts associated with the development of the project. Mitigation measures are provided where necessary. 4.6 -14 Michael Brandman Associates H\Cl t(PN- Rnb327b32]0030DEai 3270030 Sec01 Tmspo md¢
