I-5 project includes new water feature.Byline: Diane Dietz The Register-Guard A high-tech, $3 million ditch-and-pond system is a prominent part of the state Department of Transportation's ongoing interchange renovation at Interstate 5 and Belt Line Road. Work is under way on the noticeable ditch that runs along the north side of Belt Line Road next to The Register-Guard newspaper site. The ditch is a half-mile long and as deep as 25 feet in places. The state agency is including a lot more features in this ditch than it has in ditches in the past, said Karl Wieseke, assistant project manager. When the work is complete next year, the ditch is meant to provide cool, accommodating habitat for fish and other wildlife, as well as a "bioswale" filter for runoff Runoff The procedure of printing the end-of-day prices for every stock on an exchange onto ticker tape.

"This is pretty much what future work is going to look like," Wieseke said. "We're cleaning the water." In the early days, it was common practice to pipe and bury streams.

The new channel replaces a modest ditch that the Transportation Department is filling to make room for a future flyover that will move traffic from northbound Interstate-5 to westbound Belt Line Road. The ditch will connect with a waterway that eventually empties into the McKenzie River For rivers name "Mackenzie", see . The McKenzie River is a tributary of the Willamette River, 86 miles (138 km) long, in northwestern Oregon in the United States. It drains part of the Cascade Range east of Eugene into the southernmost end of the Willamette Valley. . In times of high water, officials expect the Belt Line ditch to hold fish from the McKenzie. The new channel will be lined with fabric, dirt and gravel, and then topped by a 6-inch-tall polymer honeycomb honeycomb a mosaic of closely packed units with depressed centers giving a honeycomb appearance. honeycomb ringworm see favus. honeycomb stomach reticulum. with cells about the size and shape of a football. The honeycomb will provide a solid base, so years in the future, maintenance crews can drive their equipment in the channel. Crews will fill the cells with rock and then spread a layer of topsoil. They'll lay at least two fallen trees in the channel to slow the water and provide shade and refuge for fish. Next year, they'll begin planting a mix of native shrubs, trees and upland grass. The Transportation Department will monitor the ditch for five years, making sure that the ditch has no less than 25 percent native vegetation cover after two years, 35 percent after four years and 45 percent after five years.
