ROLLING FORK STREAM AND WETLAND MITIGATION BANK SITE

200,000 Linear Feet

Casey and Marion County, KY

Construction Completed in 2017

Natural channel design was used for stream re-establishment on perennial and intermittent streams at the watershed scale. Re-establishment included construction of grade control structures in the form of riffles, vanes and habitat features such as toe-wood. Enhancement of ephemeral streams included spot treatments for bank and gully stabilization, minor meander bend adjustments, and grade control structures to control head cutting.

NORTH FORK OF THE KENTUCKY RIVER MITIGATION BANK SITE

107,540 Linear Feet

Breathitt County, KY

Construction Completed in 2018

This project was the first Kentucky mitigation bank to include a stream designated as Outstanding State Resource Water due to the presence of the federally-threatened Kentucky arrow darter. It was specifically designed to replicate ideal arrow darter habitat. During construction, surveys were performed to relocate arrow darter individuals away from the active construction. Following restoration, sampling has shown an increase in the arrow darter population on the site.

Re-establishment included placement of grade control structures, riffles, boulder cross-vanes, J-hook vanes and other habitat features such as toe-wood and large woody debris. Enhancement included spot treatments for bank and gully stabilization, minor meander bend adjustments, and grade control structures to control head cutting.

ELISHA CREEK STREAM MITIGATION PROJECT

4,227 Linear Feet

Leslie County, KY

Construction Completed in 2013

Located in the Daniel Boone National Forest, this project involved full channel reconstruction to create a meandering mountain stream. The old channel was abandoned, and a new channel was created at a higher elevation to reconnect the stream with the floodplain and to elevate groundwater to near the surface across the valley. The old channel was partially filled, and several vernal ponds were created in the old channel. This project required coordination with United States Forest Service on all aspects of the design and construction.

CRANES NEST BRANCH STREAM RESTORATION PROJECT

2,275 Linear Feet

Knox County, KY

Construction Completed in 2013

This project is in the Richland Creek watershed in the Upper Cumberland River basin, which is designated as a conservation area for fish and lamprey species. The design included Priority I and Priority II restoration and enhancement in order to improve aquatic habitats, primarily for macroinvertebrates, reduce streambank erosion and stabilize the channel bed.

GOLDEN MILE STREAM & FISHERIES RESTORATION PROJECT

5,200 Linear Feet

Golden, CO

Construction Completed in 2009

This project included a reference reach analysis, a complete hydraulic design and model using HEC-RAS, and multiple agency permitting with full design submittals. Numerous in-stream grade control features were constructed including J –hooks, cross-vanes, and boulder clusters to reduce streambank scour, braided, shallow watercourses, and improve fish habitat. Eroded banks were also improved along Clear Creek and limited foot traffic to designated high impact areas for access to the river. This project was designed specifically to increase native Brown trout spawning habitats.

JEFFERSON COUNTY OPEN SPACE RESTORATION PROJECT

1,800 Linear Feet

Jefferson County, CO

Construction Completed in 2011

This project included a reference reach analysis, hydraulic design and modeling using HEC-RAS, permitting with full design submittals, and construction of the in-stream features. This project improved fisheries and boating access to portions of the creek. Construction was performed during a historic run-off season and during the height of boating season. Our team worked closely with the rafting companies to minimize our impact on their very limited season and had a very tight construction window due to Brown trout spawning. In-stream work could only occur from June 1 through September 30. High stream flows only allowed for construction between August 1, 2011 through September 30, 2011.

COURTNEY-RYLEY-COOPER PARK STREAM RESTORATION PROJECT

1,800 Linear Feet

City of Idaho, CO

Construction Completed in 2012

This project included cross vane boulder features as well as a series of boulder clusters. The cross vanes create in- stream cover/holding water, remove excess shear stress from the near bank region, provide a stable width to depth ratio, increase sediment transport capacity, provide a natural sorting of gravel on the downstream side of the structure for spawning Redds, provide diversity of depth and structure, and create grade control to prevent further down cutting along this section of stream channel while simultaneously providing safe passage for recreational boaters. The series of boulder clusters, placed at random intervals, provide in-stream cover and scour pools for additional habitat.

BLACK SWAN STREAM RESTORATION PROJECT

5,190 Linear Feet

Boulder, CO

Construction Completed in 2018

This project included a reference reach analysis, a full geomorphic survey, a complete hydraulic design including a HEC-RAS model, channel realignment, multiple agency permitting with full design submittals, and construction. Also included in the project was flood debris removal on streambanks, historic mine tailings removal, and conformation to proposed and concurrent road and bridge construction. The project team worked closely with the Four Mile Watershed Coalition, the Four Mile Fire Protection District, landowners and stakeholders to develop and implement a design that accomplished all design goals while preserving private infrastructure adjacent to the reach.

MILL CREEK RESTORATION PROJECT
