Transportation Development
The Transportation Development Section reviews transportation issues for discretionary projects including right-of-way requirements, parking, access and other Land Development Code transportation issues. It also reviews transportation impact studies as part of the environmental review process. See additional information that may be helpful in the Planning Department's Transportation Planning section.

Frequently Asked Questions
How can I determine how much traffic my project will generate?
See the City's Trip Generation Manual.
How can I determine my projects' parking requirements?
Check Section 142 (Chapter 14, Article 2, Division 5) of the City's Land Development Code. This section also describes required dimensions of parking spaces, drive aisles and other aspects of designing the project's onsite parking.
How can I determine whether my project will require transportation studies?
Refer to Appendix A in the City's Transportation Study Manual (TSM). The rule of thumb is that if the project would be expected to generate more than 1,000 average daily trips (according to the City's Trip Generation Manual) or 500 average daily trips if the project would require a community plan amendment, a Local Mobility Analysis is required. Additionally, a Vehicle Miles Traveled (VMT)analysis would be required for projects that do not screen out from a VMT analysis based on the VMT screening criteria in the TSM.
How can I submit an "adequate" traffic impact study on its first submittal?
Refer to the the Transportation VMT CEQA Study Requirements and LMA Requirements flowchart (page 12) in the TSM and also scope the study with Transportation Development staff prior to beginning the study. Reach early agreement with staff on such issues as geographic scope of the study, locations where new traffic counts will be needed, how to handle any computer modeling, how to handle any proposed phasing, and how to address any unusual conditions.
