Traffic Study Impact Criteria in Los Angeles County

The project has a potentially significant VMT impact if it meets one or more of the criteria listed below. The impact criteria below are considered potential options that may be selected as thresholds for determining significance. These impact criteria below are based on guidance published by OPR and CARB but their applicability to a specific project shall be justified with substantial evidence and is not presumed to be appropriate.

• Residential Projects The project’s residential VMT per capita would not be 16.8%3 below the existing residential VMT per capita for the Baseline Area in which the project is located (Table 3.1.3.-1),
• Office Projects. The project’s employment VMT per employee exceeding would not be 16.8%3 below the existing employment VMT per employee for the Baseline Area in which the project is located (see Table 3.1.3.-1),
• Regional Serving Retail Projects. The project would result in a net increase in existing total VMT (see Table 3.1.3.-1),
• Land Use Plans. The plan total VMT per service population (residents and employees) would not be 16.8%3 below the existing VMT per service population for the Baseline Area in which the plan is located (see Table 3.1.3.-1),
• For other land use types, please contact Public Works to determine which of the above is an appropriate threshold of significance to be utilized (see Table 3.1.3.-1).

Table 3.1.3-1 provides the Baseline VMT for the North and South areas of the County at the time these guidelines were prepared. The Baseline VMT applied in the Transportation Impact Analysis should be consistent with the year that the transportation study begins as defined in the Scoping Document.
