December 2011 – West Canal Embankment Stability Improvements Near Oasis Park

admin — Tue, 06 Dec 2011 23:35:01 +0000

Owner:

Quincy – Columbia Basin Irrigation District

Contract Amount:

$ 1,995,620

Project Manager:	Aaron Halling
Superintendent:	Michael Melton
Assistant P. M.:	Lisa Snell

Description:	The District has identified issues associated with soft soils under the West Canal in the project vicinity. Groundwater from upland sources was determined to be part of the issue and the District installed a trench drain on the west side of the canal in the winter of 2010/2011. While this has helped to intercept and remove much of the upland drain water, water continues to keep the soft soils under the canal saturated. This project aims at replacing the soft materials with freedraining materials and further collecting and removing water from beneath the canal. This project includes mobilization to the project site, demolition of the existing canal, excavation and removal of unsuitable materials, reconstruction of approximately 850 linear feet of concrete lined canal, installation and maintenance of a pump system and dikes to bypass canal water around the construction activities, removal and replacement of canal fill material (including dewatering activities), installation of a blanket and trench drain, and construction of a sump, pump, and electrical system on the east side of the West Canal. The Engineer will identify areas in which Geomembrane cutoff wall will be required for installation by Contractor.

Owner:

Federal Highway Administration

Contract Amount:

$19,687,114.80

Project Manager:	Chad Mahoney
Superintendent:	Jonah Sproul
Assistant P. M.:	Randy Redinger

Description:	The work consists of grading, drainage, base, paving, structures, and other smaller items of work.Project length: 4.906 miles•Clark-Newton Section –This section begins at MP 68.6 and continues approximately 2.9 miles to the Teacup Recreational Area. Work consists of grading, drainage, base, paving, riprap, and structures. There is one single-span bridge across Clark Creek and seven large concrete box culverts for drainages crossing Hwy 35. The project will raise the grade of the road approximately four feet throughout most of the project length. No work will be done on the bridge crossing the dry Newton Creek channel at MP 68.0. The Clark Creek Sno-Park will be decommissioned and wetland restoration of the area will be part of the project.•White River Section –This section is also located on Highway 35 beginning approximately one-quarter of a mile before Forest Service Road 48 (MP 62.4) and continuing across the White River (MP 62.0) approximately 1 mile (MP 61.2), which is approximately one-half mile beyond the entrance to the Boy Scout Camp. Work consists of grading, drainage, base, paving, riprap, and structures. There is a three-span bridge across White River, a two-span bridge across Green Apple Creek (MP 62.1) and large culverts at North Mineral Creek (MP 61.8) and South Mineral Creek (MP 61.6). The project will raise the grade of the road approximately 15-feet above the current White River bridge. Debris material from previous White River events, above and below the bridge, will be used to construct embankments on both sections. Aggregate for base, paving, and rip-rap will come from the Tamarack Quarry, located near Trillium Lake, approximately 8 miles from the project site.Highway 35 is an important freight route for the State of Oregon and the Northwest. Throughout the project, traffic must be maintained at all times. Cumulative construction-caused delays to public traffic must be limited to no more than 30 minutes. Cumulative delay is the total delay caused by construction related operations along the entire project length. Temporary lane widths must accommodate large highway vehicles. During winter closures all recreational facilities must have full access. In addition, construction equipment and materials must be removed from the roadside, Sno-Parks, and parking lots.
