8 exceeds the typical suburban average and contributes positively to the street network’s connectivity. 4. Strategy 4B – Pedestrian Facility Improvement – As part of project frontage improvements, the Hidden Canyon Residences & Preserve development will construct approximately 0.2 miles of continuous sidewalk along its public access frontage. 5. Strategy 4C – Bikeway Network Expansion - This strategy is partially applicable. Class II bike lanes currently exist along Dublin Canyon Road and further expansions are not feasible due to the terrain. The project may coordinate with the City of Pleasanton to explore opportunities for off-site bikeway enhancements or connections to regional bicycle routes. Implementation would likely occur off-site and require City partnership or inclusion in future capital improvement planning. 6. Strategy 4H – Provide Neighborhood Traffic Calming Measures - Given the steep terrain, it is recommended to implementing traffic calming measures along internal roads and intersections within the site to enhance safety. The inclusion of traffic calming features such as speed humps, curb extensions, or lane narrowing etc. can help reduce vehicle speeds, encourage active transportation, and contribute to VMT reductions. Collectively, these measures are estimated to achieve a combined VMT reduction of 14%. The City of Pleasanton’s 2023–2031 Housing Element EIR identified a range of mitigation strategies aimed at reducing Vehicle Miles Traveled (VMT), including pedestrian facility improvements, street connectivity enhancements, bicycle infrastructure, and traffic calming. The Hidden Canyon Residences & Preserve project includes multiple feasible strategies consistent with the EIR’s recommendations, including the installation of sidewalks along the public access frontage, provision of internal intersections to improve connectivity, and incorporation of neighborhood traffic calming features. These measures reflect the types of VMT-reducing features considered in the Housing Element EIR and are consistent with its mitigation framework. Therefore, the project meets the mitigation requirements outlined in the Housing Element EIR. However, as was already acknowledged in the Housing Element EIR, implementation of these measures does not reduce VMT below the CEQA significance threshold. As a result, the project would result in a significant and unavoidable VMT impact, consistent with the conclusions of the certified Housing Element EIR.
