CEQA/NEPA Iteris has assisted several agencies update their traffic study guidelines to conform to SB 743 for their California Environmental Quality Act (CEQA) transportation analysis including the City of Irvine, City of Seal Beach and City of Laguna Niguel. Our team have extensive experience of developing Vehicle Miles Travelled (VMT) forecasts using traffic models including OCTAM and we are currently working on several project -level VMT studies. We are able to readily implement the screening and VMT calculations required for CEQA analysis as outlined in the City's recently updated Traffic Study Guidelines. Iteris is also familiar with the VMT requirements needed for input to air quality and noise studies for CEQA and National Environmental Policy Act (NEPA). TASK — MASTER PLAN Data Collection and Field Review Iteris will collect existing traffic and street light infrastructure information through a series of activities, including interviews with City traffic engineering staff, City maintenance staff (contract) and review of signal interconnect/signal system documentation. Although Iteris staff already has some knowledge and field notes of the existing traffic/communication system, it is envisioned that Iteris staff will visit and thoroughly document each City traffic signal. There are discreet components to a traffic/street lighting signal system. Each component will be evaluated and discussed separately. However, ultimately the system will function at its best when all of the components are fully and completely integrated. Components of the signal system include: • The general street network and configuration; • Full inventory of traffic signal controller hardware and software at each intersection including field hubs • Communication infrastructure between TMC and intersections • TMC infrastructure • Street light infrastructure Detailed inventory documents will be prepared to ensure City staff will have an appropriate record of existing equipment and infrastructure. Iteris will submit an Existing Conditions Technical Memorandum summarizing the findings. Surrounding System Evaluation Potentially, one goal of the Traffic Master Plan could be is to develop a strategy for the City of Santa Ana to establish communications with adjacent jurisdictions, such as Caltrans and the cities of Costa Mesa, Fountain Valley, and Garden Grove, Tustin, Irvine, and Orange. There is currently one known fiber intertie between the City and Costa Mesa, however more discussions may be needed if additional data sharing is considered. Through the use of communication links, or interties, between the City TMC and those of boundary agencies, the City will be able to share traffic signal timing data, synchronize clocks and share video surveillance data.
