If you take a stroll along the Razorback Greenway trail system in Northwest Arkansas, keep your eyes open for some special demonstration projects that have been completed to improve water quality for the Illinois River Watershed.
Five green infrastructure demonstration projects have been completed along various trailheads along the Razorback Greenway. The greenway is a multi-use trail system spanning the central corridor of northwest Arkansas, including Fayetteville, Springdale, Johnson, Lowell, Rogers, Bentonville and Bella Vista. Along the Greenway are designated areas for parking, named trailheads, as they are the access point for the beginning of a trail. With parking and amenities, these trailheads are a prime opportunity for communities to demonstrate green infrastructure to cyclist, walkers, runners and families that enjoy the trails each day.
Razorback Greenway Trail System Corridor
Green Infrastructure is the use of vegetation and porous materials to allow rain water to soak into the ground and reduce problems runoff can cause, such as erosion, flooding and transferring pollutants to nearby waterways. Many of the Razorback Greenway’s trails run along urban creeks and streams, and most are tributaries to the Illinois River. Our watershed boasts over 1,200 miles of creeks and streams, and the Illinois River and its tributaries have many designated uses set forth by the Arkansas Pollution Control and Ecology Commission (APCEC), including fisheries, primary and secondary contact recreation, drinking water supply, and agricultural and industrial water supply.
Installations of rain gardens, bioswales, porous pavers, porous pathways and native plants make up the green infrastructure elements installed. IRWP worked with the City of Fayetteville, City of Springdale, City of Johnson, City of Rogers and the new Amazeum facility to incorporate these elements into the construction of the five trailheads. Check out some of the highlights from this water quality demonstration grant project, made possible through the EPA 319 Program and the Arkansas Natural Resources Commission, with additional funding provided by an Arkansas Forestry Commission Urban Riparian Forestry grant to the IRWP to plant trees, install green infrastructure demonstration elements, and provide educational signage and programming along the Razorback Greenway. We appreciate all of our sponsors, partners, volunteers and staff that make good things possible for the Illinois River Watershed.
