Here’s the release from the US Army Corps of Engineers (Omaha District):

The U.S. Army Corps of Engineers, Omaha District, in partnership with the Boulder County Parks and Open Space Department, will hold a groundbreaking ceremony to celebrate the start of construction of an ecosystem restoration project along an approximately one-mile stretch of Lower Boulder Creek. The ceremony will take place on Thursday, October 8, starting at 12:30 p.m. MDT at the project site, which is located between N 109th Street and Kenosha Road in Boulder County approximately 3.5 miles west of the Boulder County-Weld County line and 8 miles east of the city of Boulder. Limited parking will be available along the Boulder County property access road located just east of the 109th Street Bridge. See attached map. In case of inclement weather, the ceremony will take place at the Goodhue Farmhouse located at the Carolyn Holmberg Preserve, 2009 S. 112th Street, Broomfield, Colorado.

BACKGROUND: Lower Boulder Creek once meandered across a broad floodplain that supported numerous wetlands, streamside vegetation, and associated native fish and wildlife populations. Since European settlement, the project reach and its associated habitats have been dramatically degraded by activities including upstream development, water diversions, pollution, non-native species, and gravel mining. During past on-site mining activities, the project reach of Lower Boulder Creek was channelized, and earthen levees were constructed along portions of its banks, thus disconnecting the channel from its historic floodplain and creating an impoverished stream and riparian environment. The project area is currently in a highly degraded state, which without active ecological restoration would take decades or longer to improve.

In 2011, the Omaha District completed a feasibility study which identified a feasible project to restore habitat for migratory birds and other wildlife, restore wetland and stream values, reduce invasive species and provide other ecosystem improvements. A construction contract was awarded to American West Construction LLC of Denver, Colo. for $2.6 million, which includes realigning the one-mile section of Lower Boulder Creek to restore natural meanders, in-stream habitat, and the creek’s floodplain and planting native riparian, wetland, and upland grasses, forbs, trees and shrubs along the stream and within the floodplain to greatly improve wildlife habitat. The project is expected to be complete by Fall 2016.
