Join the faculty of Lincoln College, the Logan County Soil and Water Conservation Agency, and the Logan County Natural Resource Conservation Service for a free hands-on workshop that will highlight best practices in soil erosion control and prevention. Workshop attendees will participate in an interactive lecture on local impacts of degrading soil and preventative practices for sustaining soil health from 9:00 a.m. – 11:00 a.m. Lunch will be provided for registered attendees, starting at 11:30 a.m. Guests will be able to walk the newly extended boardwalk and observe first-hand signs of erosion and view our new interpretative displays. Guests are also invited to attend the afternoon session from 1:00 p.m. – 3:00 p.m. featuring Lincoln College student projects and tours of the nature center.
Who should attend?
This workshop is free and open to the public. We encourage local landowners, environmental consultants, educators, engineers, university students, and anyone else interested in learning more about soil health and new innovative ways to prevent erosion.
Cardno provides a wide range of infrastructure consulting, design, engineering, and construction services over a broad regional area worldwide. Cardno also provides comprehensive ecological services to successfully restore habitat and ecosystem functionality, including the development and implementation of large, complex, multi-million dollar restoration projects. Cardno has a team of diverse multidisciplinary specialists, including botanists, agronomists, biologists, ecologists and engineers who plan, design, and build stream restoration projects. Cardno has over 6,000 staff working in over 130 offices, on projects across more than 100 countries around the world, with three locations in Illinois.
Indian Creek Streambank Stabilization
Cardno restored nearly 2,000 linear feet of eroding streambank along Indian Creek in Lake County, IL. Cardno completed channel surveys of this entire reach and developed a streambank stabilization design using bioengineering techniques to reduce the sediment load from the banks and upland areas to the creek. Cardno completed all the permitting and provided construction services to install stream energy dissipation structures and integrated bank treatments, including rootwad composites, cross-vanes, and single arm vanes. These methods, along with bankfull bench grading, stabilized the banks while providing improved habitat for the insects, amphibians, reptiles, and fish found within the creek and riparian corridor.
St. Joseph Creek North Branch Streambank Stabilization Design/Build
Cardno and their teaming partners Engineering Resource Associates and Thornton Equipment completed a design/build project to stabilize approximately a combined 900 linear feet of streambank at three project sites along St. Joseph Creek in DuPage County, IL Cardno conducted site assessments, stream surveys, and wetland delineations The overall design concept utilized biotechnical treatments to stabilize the stream bed and bank and provide increased stream function. Cardno completed the permitting process then oversaw project construction. Cardno provided three years of post-construction vegetation maintenance at the sites and the required vegetation monitoring and reporting.
Pheasant Branch Park Street to Century Avenue Streambank Stabilization Project
Cardno restored nearly 1,000 linear feet of eroding streambank and eroded steep slopes using ecologically sensitive techniques. Cardno completed channel surveys and developed a streambank stabilization design using bioengineering techniques. The native seed mix planted on these sites is full of species endemic to southern Wisconsin with deep extensive rooting systems. Once established, the dense roots of these native grasses and forbs trapped and held bank material in place, further reducing erosion of bank sediments while increasing the biotic diversity of the riparian corridor.
Lakeview Park Streambank Stabilization and Habitat Enhancement
Cardno stabilized approximately 1,600 linear feet of eroding streambank using ecologically-sensitive techniques to mitigate erosion by dissipating stream energy, increasing flood flow capacity, and re-establishing dense deep rooted vegetation. Stormwater from a predominately urban residential watershed drains into Lakeview Park through a 54-inch storm sewer pipe opening, flowing through the park and into Lake Mendota in Dane County, WI. Severe erosion and bank collapse and a large sediment delta had built up at the outfall as a result. Cardno’s techniques utilize native vegetation and in-channel habitat enhancement while allowing flood flow capacity and redirecting flow in the eroded areas to the center of the channel in order to mitigate bank erosion created as a result of stormwater inputs. These areas were repaired through the use of toewood to dissipate energy and provide cover for aquatic insects and fish, stone toe stabilization with bank grading and aggressive re-vegetation, log vanes to redirect the thalweg away from the bank thereby reducing near bank stress, and rootwad composites.
