Five Corners Roundabout Update: Mayor to Sign Utility Contract

Construction of the takes a big step forward tonight at the City Council meeting as Mayor Dave Earling is expected to sign an agreement with David Evans & Associates for utility work.

According to tonight's agenda, the proposed supplemental agreement includes the following:

• Waterline replacement on all five approaches. All intersection waterlines are currently old 8-inch or 12-inch cast iron waterlines. Since the intersection is being excavated and regraded as part of the project, the waterlines should be upgraded to ductile iron as part of this project.
• Stormwater drainage improvements including a detention system on the north side of the intersection and water quality treatment for runoff generated by the project. The consultant’s fee of $53,390 will be paid by the 412 water and stormwater utility funds.

Also from the agenda:

The City submitted a federal transportation grant application in April 2012 for $1,936,500 to complete right of way acquisition and construction. The grant competed against other transportation projects in Snohomish County and scored high enough to be awarded the requested funds.

The funds are currently being approved and programmed by the Puget Sound Regional Council (PSRC). The project has now received a total of $2,399,500 in federal grant funds. A 13.5% local match is required and will be funded by the 112 Street Fund.

The design phase, which began in August 2011, is scheduled for completion in Spring 2013 and the right of way acquisition phase is scheduled to begin this fall, for completion in Spring 2013. Construction is tentatively scheduled to begin in summer 2013.

“The roundabout will improve the traffic flow, make it safer and reduce emissions,” . He added that accommodating pedestrian and bicycle activity through the intersection is also a key component of the project.

“With the five approaches, there’s a lot of confusion and it can be hard to see which is the next car to go.”
