Action Requested
Discuss the Waco Street signal system functionality and future improvement planning.
Background/Discussion
There have been concerns about the functionality of the Waco Street signal system which it connects to
Trunk Highway 10, leading to the discussion of retrofitting flashing yellow left-turn arrows. As such, it has
been included in the current Capital Improvement Plan. As we have worked toward project implementation,
MnDOT has recently made us aware that they plan to replace the entire signal system at this intersection in
2029 as part of a resurfacing project. It is expected the city will incur 50% of this cost (estimated to be
$200,000) to cover the two city-owned legs of the system as part of that 2029 project. Due to the
replacement schedule MnDOT has planned, they are declining to participate in a yellow flashing conversion at
this time.
Retrofitting of flashing yellow arrows now instead of waiting would cost approximately $110,000 plus
engineering and administration. Of this, $56,000 could be reused as part of the 2029 replacement. This means
the remaining $54,000 plus engineering and administrative costs would be essentially covering roughly four
years of service for the flashing yellow retrofit and be 100% payable by Elk River. This project design and
management would also fall to the city, so, likely, it couldn't be installed until 2025 as we would need to solicit
a request for proposals before initiating a design.
