Subject:	Dual Units on Encroachment Permit Projects

Caltrans' Metric Policy has been changed to allow the use of dual units (English and Metric) on encroachment permit projects. Dual unit encroachment permit projects will no longer require an exception to Caltrans' Metric Policy. This change is effective immediately. All other projects must continue to adhere to the Metric Policy.

Dual units will be required on the plans only for those portions of the project within the State Right of Way. The only requirement is that dimensions and specifications must be in a format such that they can easily be checked against the current Caltrans Metric design standards. The preferred method for representing dimensions is English first, with the Metric equivalent shown in parenthesis.

It remains the District's responsibility to ensure that:

• The portion of the project within the State Right of Way meets or exceeds current Caltrans design standards.
• Planning or other technical documents that may be associated with the permit project, such as Project Study Reports and Freeway Agreements, must be done in accordance with current Caltrans policy and format requirements.

If you have any questions, please contact Terry Abbott, Metric Coordinator, Design and Local Programs at (916) 653-0253.
