The following is an update on Public Works projects throughout the city:
LAKE WASHINGTON BOULEVARD
The last street section on Kirkland’s 2014 list to repave is Lake Washington Boulevard, from 10th Avenue South to Lakeview Drive. Starting later this month, the City’s 2014 overlay contractor will begin preparing the arterial for a new surface. Watson Asphalt expects to grind the street’s existing surface and replace it with a new one in April.
To achieve this, Watson Asphalt will close down one of Lake Washington Boulevard’s two lanes. Watson will keep one lane open at all times.
The preparations will begin with a process known as “lowering iron,” during which crews protect the covers of sewer, gas and water utilities by removing them from the street.
Watson Asphalt had planned to repave Lake Washington Boulevard last fall. Poor weather, however, forced the contractor to delay the work until this spring.
Kirkland’s Park Lane improvements staff and contractor devised a new schedule that will allow Marshbank to substantially complete the project by May 8. The new schedule makes up for most of the time lost during the project’s first two months of construction, when Puget Sound Energy was relocating its gas and power lines and when work crews were dealing with the consequences of a water main pipe that was more fragile than expected.
Crews are finished this week preparing the street for the stormwater system of rain gardens, pipes, tree wells and underdrainage. They will begin this week installing the street’s irrigation system.
NORTHEAST 85th STREET
Kirkland’s 85th Street Improvements contractor continues to test and repair the western-most section of the 24-inch water main it has been installing since September. Meanwhile, its day crews are removing and rebuilding curb along the north side of the street. Day crews will build the sidewalk along the north side before building the curb, sidewalk and retaining walls on the south side of the arterial.
NORTHEAST 80th STREET
Kirkland will be advertising in mid-April for a contractor to install the new sewer and water main along Northeast 80th Street. Project Engineer Tuan Phan expects construction to begin in June and to continue throughout the summer. Construction will require crews to close down one lane of traffic. The City of Kirkland is establishing a detour route for cyclists.
Nearly 30 lane miles of residential roads in North Rose Hill, North Juanita and Kingsgate will receive slurry seal treatment late this summer. The City will be repaving about 10 lane miles of arterials this summer: Those arterials include:
· Finn Hill’s 141st, from Juanita Drive to Northeast 84th Street
· Kingsgates 144th and 143rd, from 132nd Avenue Northeast to the City’s limits
· North Rose Hill’s seven-block section of 132nd Avenue Northeast, from Northeast 113th to 120 Street, which borders Lake Washington Institute of Technology and 124th Avenue Northeast from Northeast 100th Street to Northeast 108th Place
· The Highlands’ 116th Avenue Northeast, from Northeast 87th Street to Northeast 95th Street
· Bridle Trails’ Northeast 60th Street, from Ben Franklin Elementary to 132nd Avenue Northeast
· Moss Bay’s Seventh Avenue South, from Fifth Place South to State Street
Design began last week on a project to replace the 66-year-old water main beneath Fourth Street, between 15th and 18th Avenues. The new eight-inch water main will increase the system’s capacity and ensure the delivery of safe drinking water. Project staff expects construction to begin in July and to continue through September. During construction, crews will keep at least one travel lane open.
FORBES CREEK BRIDGE
Many of the 20,000 motorists a day that will be cruising this summer over Market Street’s Forbes Creek Bridge near Juanita Bay Park will have no idea the bridge is under construction. That’s because most of the road work will take place beneath the bridge. By September, when project staff expects the seismic retrofit to be complete, the Forbes Creek Bridge will be ready to withstand a moderate earthquake. At times, however, crews will be working in or near the road, which will require temporary lane-closures.
INTELLIGENT TRANSPORTATION SYSTEMS
Construction will begin in early spring on the Intelligent Transportation Systems project aimed at reducing traffic congestion through intersection technology along Kirkland’s most-traveled corridors. The project’s first phase will connect the City of Kirkland’s Transportation Management Center to traffic signals along the Central Way to Northeast 85th Street corridor, as well as the Lake Washington Boulevard, Market Street and 100th Avenue Northeast corridors. Its second phase will do the same along Northeast 132nd Street, 120th and 124th Avenues Northeast in Totem Lake and along 100th Avenue Northeast and Juanita-Woodinville Way. Project engineers expect to finish construction on the first phase by fall. They expect to finish construction on the second phase in early 2016. When complete, the new Intelligent Transportation Systems technology will provide real-time traffic information to Kirkland’s transportation engineers, who can use that information to remotely adjust the synchronization of traffic signals.
A short section of Lake Washington Boulevard, just north of Northup Way, will close for at least 30 consecutive calendar days between July 7 and mid-September north of Northup Way for a project aimed at reducing flood risks and improving fish habitat. The City of Kirkland will be replacing a pair of 24-inch culverts at Cochran Springs with a box culvert that is 15-foot-wide and seven feet deep. The City will also be removing an estimated 24 tons of sediment that has accumulated downstream of the existing culverts. That sediment causes water in the stream to back-up and, on occasion, overflow the roadway. The sediment deposits also smother fish-rearing habitat.
Kirkland’s Sixth Street water main contractor will over the next three days be connecting the new 12-inch water main it installed to the existing water system in Kirkland Way, Kirkland Avenue, Central Way, Fourth Street, Second Street and Parkplace.
Water will not be available to the affected areas during this process. To minimize the effects of the process, Kar-Vel will start making those connections at 9 p.m.
Kar-Vel finished connecting the new water main March 16 to each of the 14 service lines that distribute water directly to residences. Kar-Vel expects to finish the Sixth Street water main project by March 27.
FIFTH AVENUE SOUTH
To prepare for sewer main installation beneath the trail connecting Fifth Avenue South to Eighth Street, Kar-Vel Construction cleared the trail of landscaping. It will begin installing that sewer main after its workers complete the Sixth Street water main project, which could be as early as March 30.
