Public Works DepartmentTraffic Impact Analysis Guideline Update For Vehicle Miles Traveled and Level of Service AssessmentLand Use Committee August 10, 2026 RiversideCA.gov2
•On June 16, 2020, the city council adopted Vehicle Miles Traveled (VMT) as the new transportation metric and established modified Traffic Impact Analysis (TIA) Guidelines in compliance with the state mandate. The TIA guidelines were consistent with the regional recommendations established by the Western Riverside Council of Governments (WRCOG) and an online VMT screening tool was also established.•Since adoption of the prior guidelines, WRCOG developed a small project criteria memo with additional technical analysis and updated regional travel modeling information. •Based on this updated technical information, the Public Works Department has revised the City’s TIA Guidelines and updated the VMT screening thresholds.
