Action Requested
Informational item, staff will take direction as to the Council's thoughts on future use of these systems.
Background/Discussion
In work session on October 16, 2017,we discussed crosswalks on roadways with higher speeds and non-
controlled intersection locations needing to be treated with higher level of safety devices than a standard
sign and striping. Direction was to further review costs and think about potential locations for installation
of a user actuated flashing/blinking crosswalk signs for this type of crosswalk.
Over the past couple of years,we have been asked to consider a crosswalk on Twin Lakes Road at the
north leg of Industrial Circle. Staff assembled the attached plan for required improvements to complete
an ADA accessible crosswalk with a user-actuated flashing sign. Whether this location is chosen or
another is selected,improvements to complete the crosswalk will include solar flashing signs, advance
signage, curb replacement,pedestrian ramp installation, striping, and restoration.
Staff reviewed a number of flashing sign types and recommends the most effective solution with regard
to obtaining driver response, a user-actuated rectangular rapid flashing beacon (RRFB). The product
offers more competitive pricing and is easier to replace than other user actuated LED flashing signs
available on the market.
The installation of the Twin Lakes Road crosswalk, detailed above,is not included in the 2018 budget.
The Spectrum High School Executive Director has provided a letter of support for it to be considered
with a commitment of costs participation if the improvements were to be made by this summer.
Financial Impact
The Twin Lakes Road crosswalk, as detailed on the attached plan,is estimated to cost about$20,000. A
similar installation but on a roadway without center median would be estimated to cost about$16,500.

Pedestrian -actuated warning system for
uncontrolled marked crosswalks.
• The R920 is the benchmark for
Rectangular Rapid Flashing Beacons (RRFBs)
• Ultra -efficient optical and Energy
Management System (EMS)
• Compact design to simplify installation
• Proven technology platform
• Exceeds FHWA standards
RRFBs have been found to provide vehicle yielding rates
between 72 and 96 percent for crosswalk applications,
including 4lane roadways with average daily traffic (ADT)
exceeding 12,000*.
Superior Design and Technology
The R920 utilizes a self-contained solar engine integrating
the energy management system with an on -board user
interface, housed in a compact enclosure together with the
batteries and solar panel. In low light conditions, the ambient
auto -adjust option provide over -lighting protection and
system efficiency, while still meeting MUTCD light intensity
requirements.
Easy Installation
With its highly efficient and compact design, installation is
quick and uncomplicated, dramatically reducing installation
costs. Retrofitting can be done where existing sign bases
are used to enhance existing marked crosswalks in minutes,
and new installations can be completed without the cost of
larger poles and bases.
Advanced User -interface
The R920 is the first RRFB with an on -board user interface
and display for quick configuration and status monitoring.
It allows for simple in -the -field set-up adjustment to flash
duration, ambient settings, and night intensity. Settings are
automatically sent wirelessly to all units in the system.
Reliable
Designed with Carmanah's industry leading solar modeling
tools to provide dependable year -after -year operation.
Trusted
With thousands of installations in the field, Carmanah solar
beacons and solar LED lights have become the benchmark
in traffic applications and other transportation applications
worldwide.

Thank you for your work in pulling together a possible plan for the installation of a crosswalk and lighted signage on
Twin Lakes Road. As you are aware from previous conversations over the past couple of years, Spectrum believes a
crosswalk and lighted signage at this location would go a long way toward increasing pedestrian safety.
Following review of your suggested plan, Spectrum is very interested in pursuing this option further with the City of Elk
River. We recognize that the City does not have this project currently budgeted for in this fiscal year. However, we
wanted to make you aware that if the City were able to make it happen prior to the start of the 18-19 school year at the end
of August, Spectrum would be willing to contribute $5,000 toward the cost of the project.
Again, thank you for your advanced work, and please let us know what the next steps should be in pursuing this
opportunity with the City of Elk River.
