i=rewert Traffic Impact Study 2.0 STUDY METHODOLOGY Traffic impacts related to the proposed project were evaluated for both compliance with applicable regulatory documents and environmental significance as defined in the California Environmental Quality Act(CEQA).The CEQA analysis was conducted in accordance with the CEQA Transportation Analysis Guidelines finalized in September 2020 by San Joaquin County.As of July 1, 2020, intersection level of service (LOS) can no longer be used to determine significant CEQA impacts. However, a local traffic impact study was conducted to determine consistency with San Joaquin County plans and standards. This non- CEQA analysis was conducted based on the Traffic Impact Study Guidelines for San Joaquin County, dated November 2008, as updated. 2.1 VEHICLE MILES TRAVELED This study evaluates project-related VMT as outlined in the adopted San Joaquin County VMT methodology, as outlined in the CEQA Transportation Analysis Guidelines. The Governors Office of Planning and Research (OPR) Technical Advisory(December 2018) provides guidance to analysts and local jurisdictions for implementing VMT as a metric for determining the transportation impact for land use projects.The OPR guidelines state that for analysis purposes, "VMT", refers to automobile VMT,specifically passenger vehicles and light trucks. Heavy truck traffic is typically excluded. The County guidelines include a screening process that describes scenarios in which a project would be exempted from a VMT analysis requirement, including screening by project type and maps identifying low- VMT areas. Since the screening criteria mentioned above do not apply to this project, a qualitative VMT analysis was prepared. 2.2 LEVEL OF SERVICE ANALYSIS METHODOLOGY Although Level of Service (LOS) is no longer relevant to CEQA, LOS can be used to determine conformity with an adopted general plan or congestion management program. LOS is a qualitative measure that describes operational conditions as they relate to the traffic stream and perceptions by motorists and passengers.The LOS generally describes these conditions in terms of such factors as speed and travel time, delays,freedom to maneuver,traffic interruptions, comfort, convenience, and safety. The operational LOS are given letter designations from A to F,with A representing the best operating conditions (free- flow) and F the worst(severely congested flow with high delays). Intersections generally are the capacity- controlling locations with respect to traffic operations on arterial and collector streets in urban areas. Signalized intersections The study intersections under traffic signal control were analyzed using the 6th Edition Highway Capacity Manual (NCM) Operations Methodology for signalized intersections described in Chapter 18(HCM W1 Ed.).This methodology determines LOS based on average control delay per vehicle for the overall intersection during peak hour intersection operating conditions. Control delay includes initial deceleration delay, queue move-up time, stopped delay, and final acceleration delay.The average control delay for Page 18 TJKM
