Transportation Impact Study for Hidden Canyon Residences & Preserve March 2023 Page | 7 IMPACT FINDINGS Transportation impacts resulting from the proposed project were found to be less than significant, and, therefore no transportation mitigations would be required. The proposed project is forecast to generate an average of 407 daily vehicle trips, including 22 weekday a.m. peak hour vehicle trips (six inbound and 16 outbound), and 56 weekday p.m. peak hour vehicle trips (33 inbound and 23 outbound). • Motor vehicle traffic impacts resulting from the proposed project were found to be less than significant based on the City’s level of service (LOS) standards. The anticipated project traffic would result in roughly a three percent increase in peak-hour traffic on Dublin Canyon Road at the Canyon Meadows Drive intersection, which would not significantly affect existing conditions. All study intersections were found to operate at an acceptable LOS under all study scenarios, with and without the proposed project, and traffic conditions resulting from the proposed development would not conflict with adopted congestion management agency standards. • Impacts to bicycle and pedestrian facilities were found to be less than significant since the proposed project is not anticipated to create or worsen a hazardous condition for bicyclists or pedestrians; or otherwise interfere with bicycle or pedestrian accessibility to the project and adjoining areas; or conflict with an existing or planned pedestrian or bicycle facility; or conflict with policies related to bicycle and pedestrian activity adopted by the City. As part of the project: existing striped shoulders bordering the site would be updated to meet Class II bicycle lane standards, including the provision of bicycle lane treatments where the project would provide an eastbound right-turn lane approaching the EBRPD Driveway. • Impacts to transit were found to be less than significant because the project would not conflict with existing or planned transit services, or with transit policies adopted by the City, Alameda County Transit Committee (ACTC), Livermore Amador Valley Transit Authority/Wheels (LAVTA), or Bay Area Rapid Transit (BART) for their respective facilities in the study area, and the project is not anticipated to create significant demand for public transit services above capacity. • Emergency access is anticipated to be adequate because an EVA road serving lots 1-28 would provide a secondary connection between Dublin Canyon Road and Street B within the residential portion of the site, in addition to direct access via Street A. Secondary EVA access to the EBRPD parking lot would also be provided via Lots 29 and 30. • The project is not anticipated to substantially increase hazards due to the project design. Sight distance approaching each of the proposed project intersections was found to be adequate, based on the applicable speeds on Dublin Canyon Road. The location and design of the entrances would not affect conditions at the existing intersections of Dublin Canyon Road with Canyon Creek Circle and Canyon Meadows Drive. • The proposed signal would improve operations at the intersection of Dublin Canyon Road and Canyon Meadows Drive. During the peak hours, the intersection would operate at LOS C or better under all “plus Project” conditions. Furthermore, the installation of the signal would improve roadway safety by limiting concurrent vehicular path conflicts between Canyon Meadows Drive and existing church driveway and provide a protected pedestrian crossing across Dublin Canyon Road for residents trying to access the nearby park.
