The Sonoma County Vehicle Miles Traveled Mitigation and Reduction Calculator was developed by SCTA and Sonoma County jurisdictions in order to assist member agencies in their efforts to comply with the requirements of SB 743. It can be used to evaluate the effectiveness of mitigation measures on the transportation effects of land use projects under the California Environmental Quality Act (CEQA). The tool is an Excel workbook that was modeled after the San Diego Association of Governments (SANDAG) VMT Reduction Calculator Tool and the Alameda County VMT Reduction Calculator Tool. The Sonoma County tool incorporates data from the Sonoma County Travel Demand Model and is customized to represent local conditions.
