B23-153CA - Middle Tributary Upstream of I-25 Channel Restoration

The City of Colorado Springs proposes to repair and stabilize existing channel incision and bank erosion along the Middle Tributary Channel. Middle Tributary Basin is located in El Paso County, in the City of Colorado Springs, Colorado.  The Channel is near the bottom of the Basin, directly East from I-25, and upstream approximately 1,500 feet. The lower portion of the project is located on United States Air Force Academy property (USAFA) and the upper half is within City property.
The project improvements generally consist of regrading the channel with the installation of creek features including rock riffles, grouted boulder drop structures, boulder vanes, buried sheet pile, soils lifts and extensive revegetation.  Special care is required to minimize impacts to the threatened Preble’s Meadow Jumping Mouse habitat within the project area.
