MEMORANDUM
DATE: Agenda Item 1.A
March 24, 2009
TO:
Mayor and City Council
FROM:
Ron Moorse, City Administrator
SUBJECT: Funding for Design Work on Options for Addressing Traffic
Movement Issues related to the Relationship Between the CR H and
CR I interchanges
Background
As part of the design process for the CR H/I35W interchange, the current and projected traffic
congestion on I35W is projected to cause congestion issues related to the weaving movements
that occur between the traffic entering onto northbound I35W from the CR H interchange , and
the traffic exiting from northbound I35W at the CR I interchange. These congestion issues need
to be resolved to obtain design approval from both Mn/DOT and the Federal Highway
Administration, and to provide an opportunity to obtain interchange funding from Mn/DOT.
Review of Options
While Mn/DOT’s proposed solution to the congestion issues is to close the exit from northbound
I35W to CR I, this is an important movement for City of Shoreview residents and the City of
Shoreview. In a meeting between Mn/DOT, the Cities of Shoreview and Arden Hills, and Mark
Benson, Ryan’s traffic engineer, two additional solution options were identified. I have attached
a letter from Mark Benson to Mn/DOT describing the options and setting out a Scope of Services
for the review of the options. I have also attached the concept plans for each of the options.
As the scope of services indicates, the review of the options has a cost of $50,000. Mn/DOT has
agreed to provide $25,000 of funding, if there is a local match of $25,000. Ryan has agreed to
fund the cost of developing the concept plans, which is about $5,000. This leaves approximately
$20,000 of the local match to be funded.
Based on the funding offered by Mn/DOT, and the partial funding of the local match by Ryan, it
is recommended that the City provide the remaining $20,000 of funding. The City’s contribution
could be reimbursed from the proceeds of future Federal or State funding for the project design.

Council Direction Requested
Provide direction regarding whether the Council supports the City funding approximately
$20,000 of the cost of developing and reviewing design options to address congestion issues
between the CR H and CR I interchanges.
