Jean ‑ I have reviewed the application materials and offer the following preliminary comments.

*        A Traffic Movement Permit was not issued during the 2005 expansion project.  In 2005 the applicant provided traffic analyses that indicated new traffic generation did not trigger a Traffic Movement Permit.  The applicant should provide a historical summary of traffic changes over the last ten years, combined with traffic from this addition, in an effort to assess whether a Traffic Movement Permit is required.

*        I have reviewed the parking demand analysis and how additional vehicles will be accommodated in MMC parking facilities.  Based upon information provided, I find parking conditions to be acceptable.

*        The applicant indicates that the project will be expanding elements of the TDM plan by providing a car share vehicle and adding bicycle parking.  Details of these added elements should be provided.

*        I have reviewed the traffic study prepared by Gorrill‑Palmer Consulting Engineers, Inc. and generally find the methods used to be acceptable.  I continue to review the safety analysis and the conclusions provided.

If you have any questions, please contact me.
