Develop a VMT Impact Fee Program 

Measure

Through this measure, the County aims to reduce on-road transportation emissions by developing a vehicle miles traveled  (VMT) Impact Fee program that can fund VMT reduction projects in the unincorporated County. Under this proposed  program, developers would be required to pay a VMT Impact  Fee to help reduce regional VMT. This fee would apply to applicable development projects if the developers were unable to reduce onsite VMT to meet the VMT significance thresholds. 

This measure was deemed not quantifiable because there was insufficient data to quantify reductions. The quantification of this measure would depend on how many individual projects  would be subject to the VMT Impact Fee Program, and whether they would be required to first mitigate onsite VMT versus paying into the new VMT Impact Fee program. These details cannot be known and cannot be reasonably estimated with publicly available data until nexus studies and draft  ordinances have been developed identifying those assumptions and parameters.  

​​Ac​tions

Action GHG-08-a: Conduct a VMT Impact Fee Program nexus study to identify key VMT mitigation projects in the unincorporated County and the costs per VMT of project implementation. The projects identified in the nexus study must be proven to be:

  • Additional to any VMT reduction projects or programs that would be implemented without the VMT Impact Fee as a funding source.
  • Verifiable for monitoring of achieved VMT reductions after project implementation.
  • Lasting the duration of the project's operational lifespan for which VMT is being mitigated through the VMT Impact Fee.
  • Having direct public benefits to low-income residents and Environmental Justice Communities.
  • Having appropriate nexus between new development projects and off-site VMT mitigation projects, including proximity of off-site VMT mitigation projects to new development projects within the unincorporated County.

 Status: Not Started. 


Action GHG-08-b: Based on the findings of the nexus study, adopt an ordinance establishing the VMT Impact Fee Program that allows project proponents to pay for offsite VMT mitigation after all feasible onsite mitigation has been implemented and project VMT is still above the significance threshold. Detailed feasibility criteria will be developed and will include appropriate economic considerations to ensure that all feasible onsite VMT mitigation measures are prioritized and implemented prior to the development of offsite mitigation measures in the form of VMT Impact Fees. Status: Not Started. 


Action GHG-08-c: Establish a VMT Impact Fee fund to invest in VMT mitigation projects and a fee collection mechanism into which developers will pay. Status: Not Started. 


Action GHG-08-d: Create a VMT monitoring program that allocates County resources to the annual monitoring and reporting of VMT reductions achieved through the implementation of VMT mitigation projects funded through the VMT Impact Fee and compare against the estimated VMT reductions at the time of VMT Impact Fee collection. Status: Not Started. 


Action GHG-08-e: Reassess the projects available for offsite VMT mitigation through the VMT Impact Fee Program every three years, including the effectiveness of VMT mitigation through monitoring and reporting and the additionality of eligible projects. Status: Not Started. 


Action GHG-08-f: Develop an informational packet on the requirements and applicability of the VMT Impact Fee Program, focused on educating project applicants and County staff. Status: Not Started. ​

​Statu​s of Impleme​​n​​t​​ation

The County is currently evaluating the estimated cost and scope to develop a VMT mitigation program for land use projects. This effort is being coordinated between the Department of Transportation and Office of Planning and Environmental Review. Eventually it is likely that a consultant will be hired to conduct the nexus study and develop the fee program. The County is also collaborating with the Sacramento Transportation Authority (STA) on a potential VMT mitigation program for transportation projects.

​O​bjecti​​​​ves

Develop a VMT Impact Fee Program to require developers to contribute to regional VMT reductions when project-specific VMT cannot be mitigated to below significance thresholds after all feasible onsite mitigation has been implemented.​​
