Lower Boulder Creek Aquatic Ecosystem Restoration Project

Project Overview

The Lower Boulder Creek Aquatic Ecosystem Restoration Project is a joint endeavor of Boulder County Parks & Open Space and the U.S. Army Corps of Engineers - Omaha District to restore an approximately one-mile reach of Lower Boulder Creek located between N 109th Street and Kenosha Road on the county's Alexander Dawson open space property. This area was degraded by past mining and creek channelization.

Restoration Plan

In June 2011, the Corps completed a feasibility study for the project, which recommended a preferred restoration plan. This conceptual plan was formally approved by the Corps of Engineers and Boulder County in summer 2011.

Project Status

The project is currently in the Design and Implementation Phase. The Corps of Engineers with the assistance of Parks & Open Space will complete the final restoration design by fall 2014. Project construction is anticipated to begin in late 2014 or early 2015 and be completed within one year.


The project, which was originally proposed in the Lower Boulder Creek and Coal Creek Open Space Master Plan, is being carry out under the authority granted to the Corps of Engineers in Section 206 of the Water Resources Development Act of 1996. Section 206 allows the Corps of Engineers to undertake restoration projects in aquatic ecosystems, such as rivers, lakes, and wetlands, with a non-federal sponsor, such as Boulder County. The program provides up to $5 million in federal funding and requires a 65% federal / 35% local sponsor cost-sharing agreement.
