With Mitigation 4.16.1 Impact Determination in the EIR Increase in Traffic/ LOS The Certified EIR stated that the significance of local street segment impacts related to excess vehicle traffic is usually determined on a case -by -case basis because each street segment has unique characteristics. The City has established goals for maintaining LOS D or better on local streets. The ability to determine LOS on a local street is very difficult for several reasons. Most importantly, each street is unique in character. Local streets vary considerably in terms of street width, adjacent land uses, density, presence of schools, day care, senior housing, proximity to other major streets, and other factors. A level of traffic which may be perceived as too much on one street may be acceptable on another. Furthermore, a lane of traffic, carrying the traditional LOS D volume on an arterial street, would be far too much traffic for most residential streets. The City has established LOS guidelines based on average daily traffic (ADT) along particular street segments depending on the street segment type. The maximum roadway capacities, in ADT, are based on the number of lanes and roadway classification. For the Overlay Zone, the LOS for roadway segments is determined by comparing the ADT volumes for each roadway segment to the appropriate LOS D capacity for that roadway classification. When the ADT volume is within the LOS D volume criteria, the roadway segment is operating at an acceptable LOS. The Certified EIR presents the ADT segment analysis for 31 roadway segments in and surrounding the Overlay Zone, both for existing conditions and Cabrillo Town Center City of Santa Ana Technical Memorandum August 2023 City Council 18 — 617 10/3/2023
