TO: CITY COUNCIL
FROM: GEOFF ENGLISH, DIRECTOR OF PUBLIC WORKS6-,At
SUBJECT: CONSIDERATION OF PURCHASE OF IN- PAVEMENT
REPLACEMENT LIGHTS FOR EAST BRANCH CROSSWALKS
DATE: MARCH 24, 2015
RECOMMENDATION:
It is recommended the City Council approve the purchase of twenty -eight solar
powered, radio controlled light units from Silicon Constellations in the amount of
$30,800.59.
IMPACT TO FINANCIAL AND PERSONNEL RESOURCES:
$31,000 in Gas Tax funds were previously allocated by the City Council for this
purchase with the Mid -Year Budget. Minor staff time was expended to secure
the quotation and prepare the staff report. City staff will spend approximately
two (2) full -days with a three (3) staff crew to complete the light replacement
work.
BACKGROUND:
A majority of the work on the East Branch Streetscape project was completed in
2009. The East Branch Streetscape project included the installation of
crosswalks at the intersections of East Branch Street and Bridge Street and East
Branch Street and Short Street. The crosswalk portion of the project included the
installation of solar - powered, radio - controlled, in- pavement flashing lighting
systems.
The type of crosswalk warning system utilized allowed for the installation without
trenching through the asphalt and sidewalk to install electrical conduit. In
addition, the push -button used to activate the lights can be moved or relocated
without retrenching, which was a desirable feature during the design phase of the
East Branch Streetscape process.
ANALYSIS OF ISSUES:
There are fourteen individual solar powered, radio controlled light fixtures at each
of the lighted crosswalks in the Village. Each light fixture has a bulb on both
sides of the unit. Of the total twenty -eight light units, only eight light units are
fully functioning. The other twenty light units have one or both bulbs burnt out,
requiring replacement. The manufacturer's warranty covers light replacement for
five (5) years. We are outside of the warranty coverage period.

The in- pavement crosswalk warning light systems at Short Street and Bridge
Street in the Village are a pedestrian safety enhancement feature and receive a
significant amount of use due to the high pedestrian traffic volume. Staff is
recommending replacement of this specific, proprietary replacement light units
because, although costly, it is the most cost effective option to retain an in-
pavement lighting system.
The two primary options for pedestrian warning lights are the following:
® Solar powered rapid - flashing beacon lights on pedestrian signs on the
side of the road. These pedestrian warning systems are less expensive to
install and replace, but do not have the in- pavement light feature.
Installation of four new rapid - flashing beacon lights pedestrian signs of this
style is estimated to be approximately $15,000.
The City has installed several of these rapid - flashing beacon light systems
on several mid -block crosswalks in Arroyo Grande. They are less
attractive and may not be as suitable to compliment the Village
streetscape theme.
® Hard -wired in- pavement lighting systems are available and the individual
lights units may be purchased at a lower replacement cost, however
trenching would be necessary to install electrical wire and conduit to
provide power to the lights. In addition, the systems would need to be
connected to an electricity supply involving additional trenching and
electrical connections. Lee Wilson Electric, our traffic signal
maintenance company provided a preliminary installation quote of $25,000
to $30,000 for each location.
Staff does recommend looking at alternative options for in- pavement, flashing
lighting systems prior to the end of the five -year warranty period and prior to the
next resurfacing project for East Branch Street.
ADVANTAGES:
The solar powered, radio controlled light units from Silicon Constellations can be
installed without trenching through the asphalt and sidewalk to install electrical
conduit. In addition, the push - button to activate the lights can be moved or
relocated without retrenching, which was a desirable feature during the design
phase of the East Branch Streetscape process. Replacement lights are also
easy to install with minimal investment of staff resources and would be the
quickest and least costly alternative for replacement at this time.
