Subject: 	MMC Building Addition Project - Final Traffic Comments

Jean ‑ The following represents my final comments and a status update from my June 5th 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.

Status: The applicant has provided a summary of traffic permits for the project and I concur that the site and this project is in compliance.

*        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.

Status: No comment necessary.

*        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.

Status: The applicant has provided supporting information on enhancing their site TDM Plan. I concur with Jeff Levine's Memorandum dated July 3, 2013 that suggests the applicant consider the noted suggestions as alternative measures.

*        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.

Status: I have reviewed the traffic study and in my professional opinion the project will not have a significant impact on traffic conditions in the vicinity of MMC. The traffic study did identify safety problems in the project area and accordingly the applicant shall be responsible for implementation of mitigation strategies recommended in the study.  The applicant shall coordinate with DPS prior to proceeding on the noted recommendations.

If you have any questions, please contact me.
