Traffic Study–Public Works

When a new development is proposed within the unincorporated areas of the County, the Traffic Division of the Department of Public Works provides a review of the traffic related portions in cooperation with the Department of Land Use Services. For projects which generate a sufficient amount of traffic, more than 100 trips during the peak hour, or are in areas where congestion exists and/or areas of concern, a traffic study may be required as part of the project’s approval process. The Traffic Division is responsible for reviewing and approving these traffic studies.

Other possible requirements related to these permits include, but are not limited to: None
