Development Review
When a new development is proposed in the County’s unincorporated areas, the Traffic Division evaluate projects processed through Land Use Services for  traffic-related aspects of the project. Developments generating significant traffic, over 100 trips during peak hours, or located in congested areas may require a traffic study, which the Traffic Division reviews and approves. The Traffic Division reviews street improvement plans processed through Land Development for signing and striping requirements. The Traffic Division is also responsible for calculating transportation fees associated with development. Please see the Regional and Local Transportation Fee Schedules for fees associated with development.
To submit
Traffic studies, trip generation reports, and VMT analysis, please submit in EZ Online Permitting (EZOP) at EZOP – Traffic Study Submittals. An initial deposit is required for review of the studies/reports and will be invoiced after application submittal.
