5. Environmental Anal y 'mmm= is TRAFFIC AND CIRCULATION 5.3.3 Thresholds of Significance According to Appendi c G of the C E A Guidelines, a project would normally have a significarnt effect on the environment if the project could: T 1 Cause an increase in traffic which is substantial In relation to the existing traffic load and capacity of the street system i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections). T 2 Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways. T-3 Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks. T-4 Substantially increase hazards due to a design feature (e,g., sharp curves or dangerous intersections) or incompatible uses e.g., farm equipment). T-5 Result in inadequate emergency access. T-6 Resu It in inadequate parking capacity. T 7 conflict with adopted policies, plans, or programs supporting alternative transportation e.g,, bus turnouts, bicycle racks). The Initial Study, included as Appendix At substantiates that impacts associated with the following thresholds would be less than significant: ffl • Threshold T-2 • Threshold T-3 • Threshold T-5 • Threshold T-6 • Threshold T= These impacts are not addressed in the following analysis. City of Santa Ana Significance Thresholds The City of Santa Ana has criteria for traffic and circulation impacts within the City. As defined by the city, a project is considered to have a significant impact on the operation of are intersection when one of the following occurs: • The addition of project traffic results in LOS dropping from acceptable levels (LOS D or better) to unacceptable Levels (LOS E or F; If an intersection is LOS E, a project results in a significant impact if the addition of project traffic results in LOS F; or • If an intersection is already at LOS F, then the project has a significant impact if the addition of project traffic causes an increase of o.2 in the volume to capacitor VC ratio pursuant to the Iola methodology or two seconds of additional delay pursuant to the HCM methodology FaiybavenlLincoln and Santa ClaralLincoln Intersection Modifications City ofSanta Ana • Page 5.3-13 Supplement to the Santa Ana Second Mal'n Track Pyoject EIR Resolution No. 2009 -034 Page 91 of 130
