Memorandum
Attached for your review and approval is a resolution that authorizes execution of a temporary permit to enter between the City of Ann Arbor and the National Railroad Passenger Corporation (Amtrak) for the Southside Interceptor Sanitary Sewer Diversion Project. Also attached, please find a copy of the Temporary Permit to Enter upon State of Michigan Property.

This flow split will allow both sewers to function at a high level.
During the design process for this project, it became obvious that it would be necessary to occupy a portion of the MDOT-owned railroad right-of-way to allow the project's construction to proceed without undue delay or hardship. The Temporary Permit to Enter (TPE) will also allow construction equipment, materials, and personnel to be in the railroad right-of-way in order to properly execute and oversee the work.
The TPE is a standard agreement that Amtrak requires (without negotiation) all parties to execute for work performed within their right-of-way. The agreement defines each party's rights and resp...
