Tillamook Estuaries’ $12M Project Restores Oregon Wetlands By Lori Tobias

ing communities tackle challenges, to lend a hand. “They came to town and an engineer was brought on board,” Phipps said. “Northwest Hydraulic Engineering started modeling different potential projects to address flooding. A number of activities took place to help smooth the way for flood waters to exit more quickly. The project started to develop to involve some land the county had purchased in 1999 at the mouths of the Wilson, Trask and Tillamook Rivers — which all converge at the same point. This property sits in the middle of that. It looks like a mitten from above. There is this land sitting down there and suddenly the wheels started turning. When modeled, it showed the greatest flood mitigation.”

For decades, folks in Tillamook, Ore., looked for ways to diminish the flooding that so frequently troubles this agricultural community, damaging property, threatening lives and generally shutting down town. “We had a series of 100-year events,” said Lisa Phipps, executive director of the Tillamook Estuaries Partnership. “It was obvious that we were going to experience these events on a fairly regular basis, causing impacts on the economy, as well as lots of frustrations and lots of concerns.” Then in 2007, state Sen.

Reconstruction Along I-90 in the Heart of Idaho’s Silver Valley By Jennifer Rupp CEG CORRESPONDENT

Scarsella Bros. performs bituminous removal to subgrade.

The small town of Mullan in Shoshone County, Idaho, marks the start of a 4.5-mi. reconstruction project along I-90 extending east to the Idaho/Montana state line. By the 1980s, this area known as the Silver Valley, had produced more than a billion ounces of silver, 3 million tons of zinc, and 8 million tons of lead, totalling more than $6 billion in value, ranking the valley among the top 10 mining districts in world history, according to the Spokane Daily Chronicle. N.A.Degerstrom Inc. of Spokane Valley, Wash., began work in the fall of 2014 with the bridge overlay in the westbound lane of I-90. Work continued with traffic reductions to a single lane in each direction, utilizing crossovers where necessary.

Prime Contractor ACME Concrete Paving of Spokane headed up the paving, using 50,000 sq. yds. of asphalt. Frank Gurney Inc., also of Spokane, worked on all guardrail metal and concrete, crash attenuators, delineation and snow poles. Zannetti Brothers, based in Osburn, Idaho, hauled out 82,000 cu. yds. of excavation and hauled in base. Scarsella Bros Inc. of Kent, Wash., was responsible for removal of obstructions, bituminous and concrete, all drainage, dirt work, runaway truck ramp repairs, slope repair, and ¾ base placement. The roadway was fully opened in midNovember with some miscellaneous change order work to resume in spring of 2017. The Idaho Transportation Department (ITD) made accommodations to minimize delays and traffic interruptions. see ECONOMY page 8
