State Air Resources Board: vehicle miles traveled: maps.
The key impact of SB 670 will be on transportation planning and environmental policy. By establishing a standardized methodology to assess VMT, local agencies will have access to accurate data that will empower them to make informed decisions regarding development projects. The availability of statewide VMT data is expected to facilitate better targeting for housing and infrastructure investments, making it instrumental in aligning local efforts with state climate objectives. It will also provide a valuable resource for determining transportation impacts of new developments, especially when implementing existing state laws like Senate Bill 743.
Senate Bill 670, introduced by Senator Allen, seeks to address transportation-related emissions by mandating the development of a methodology for assessing and mapping vehicle miles traveled (VMT) in California. The bill aims to provide a clear representation of light-duty VMT at local, regional, and statewide levels, thus supporting effective planning and decision-making. This initiative is aligned with California’s broader climate and equity goals, particularly in light of targets set for 2030, where it aims to reduce per capita VMT by at least 25% below the levels established in 2019.
The sentiment surrounding SB 670 appears largely supportive, especially among environmental advocates and policymakers focused on climate change mitigation. Proponents argue that accurate VMT mapping is essential for understanding transportation impacts and fostering sustainable growth. However, there may also be concerns regarding the practicality of implementing the new requirements among local jurisdictions, particularly those that may lack the resources to effectively utilize the methodology and maps developed under the bill.
Notable points of contention may arise around the timeline for implementation, which requires the State Air Resources Board to adopt the methodology by January 1, 2025, and publish maps within six months thereafter. This fast-tracking could raise questions about the adequacy of the resources allocated for technical assistance to local agencies seeking to incorporate VMT data into their planning processes. Additionally, the debate may center on the balance between state guidance and local autonomy in transportation planning, with some local entities potentially wary of being mandated to follow a state-developed framework.
