Background: A busy residential 3 way stop in Sammamish, WA
Sammamish, Washington, sits just east of Seattle and has a population of 65,000 residents. This suburb community is located on a plateau and is bordered by Lake Sammamish to the west and Snoqualmie valley to the east.
Similar to many communities that surround Seattle, Sammamish has seen steady growth over the last few years. New housing developments, businesses and retail stores have been added, creating more and more traffic on their roadways.
In a residential part of the City, a busy 3-way stop was generating complaints from the community as some drivers were ignoring the stop signs, in addition to driving on to a resident’s personal property.
The Challenge: Dense Tree Cover and No Readily Available AC Power
The location of this 3-way stop is in an area with dense tree cover and without easily accessible AC power. To increase driver compliance rates at the stop signs, LED lights would be needed to increase visibility; however, power would be needed.
Without electrical infrastructure onsite, adding AC power would require trenching – costing the city time and money. In addition to the power challenges, the City wanted a lighting solution that only flashed when activated by vehicles.
