LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 2-17-3881-1 Tustin Avenue Retail, Santa Ana N:\3800\2173881 - Tustin Avenue Retail, Santa Ana\Report\3881 - Tustin Avenue Retail, Santa Ana TIA 03-13-18.doc 2 Project. Near-term (Year 2019) cumulative daily and peak hour traffic forecasts were projected by incorporating a one percent (1.0%) annual growth rate and the trip generation potential of twenty- four (24) cumulative projects. 1.2 Study Area Four (4) key study intersections and one (1) key roadway segment have been identified for evaluation. Of the four (4) identified intersections, two (2) are located within the City of Santa Ana and two (2) are located in the City of Tustin. The one (1) roadway segment is located within the City of Santa Ana. The four (4) intersections/one (1) roadway segment listed below provide regional and local access to the study area and define the extent of the boundaries for this traffic impact investigation. Key Study Intersections 1. Tustin Avenue at Fourth Street (Santa Ana) 2. Tustin Avenue at First Street (Tustin) 3. SR-55 SB Ramps at Fourth Street (Santa Ana/Caltrans) 4. SR-55 NB Ramps at Fourth Street/Irvine Boulevard (Tustin/Caltrans) Key roadway segment A. Tustin Avenue, between Fourth Street and First Street (Santa Ana) Figure 1-1 presents a Vicinity Map, which illustrates the general location of the Project and depicts the study locations and surrounding street system. The Level of Service (LOS) investigations at these key locations were used to evaluate the potential traffic-related impacts associated with area growth, cumulative projects and the proposed Project. When necessary, this report recommends intersection and/or roadway improvements that may be required to accommodate future traffic volumes and restore/maintain an acceptable Level of Service, and/or mitigates the impact of the project. Included in this Focused Traffic Impact Analysis are:  Existing traffic counts,  Estimated project traffic generation/distribution/assignment,  Estimated cumulative project traffic generation/distribution/assignment,  AM and PM peak hour capacity analyses for existing conditions,  AM and PM peak hour capacity analyses for existing plus project conditions,  AM and PM peak hour capacity analyses for future near-term (Year 2019) traffic conditions without and with the proposed Project,  Site Access Evaluation,  Congestion Management Program Compliance Assessment, and  Roadway Segment Evaluation. 2-61
