All proposed development projects within the City of Torrance, except when screened for exemption, must provide the following reports:

1. Vehicle Miles Traveled (VMT)-Based Traffic Impact Analysis (TIA)

A TIA needs to be submitted to comply with CEQA requirements. Background and information on the preparation of this report is provided in the City’s TIA Guidelines for Land Use Projects.

2. Level-of-Service (LOS)-Based Traffic Circulation Analysis (TCA)

A TCA is required by the City to ensure that the project will not impose a burden to the City’s transportation network. The City’s TCA Guidelines page provides information on the preparation of this report.    

Other studies may be required by the City on a case-by-case basis, such as left-turn lane queuing analysis, drive-through queuing analysis, site circulation analysis).

The following flowcharts illustrate how a project can be exempted from TIA and/or TCA preparation. The references in brackets indicate the section in the City’s TIA Guidelines that provide additional information on the steps. Figures 6 and 7 of the TIA Guidelines present the flowcharts in printable form.
