How the IRWP rebate works
The Illinois River Watershed Partnership, a Northwest Arkansas nonprofit, runs a Green Infrastructure Program that funds up to 50 percent of project costs for homeowners installing a rain garden, bioswale, or permeable surface. The program does not publish a fixed dollar cap. Instead of a straight cash rebate, the remaining cost is covered by matching funds: in-kind labor, equipment, cash, or funding from another grant.
Who this program is for
The program prioritizes properties in the Illinois River watershed, which runs through several Northwest Arkansas cities: Rogers, Fayetteville, Siloam Springs, Bentonville, and Springdale. It is a regional, watershed-based program rather than a statewide one, so eligibility depends on whether a property drains into the watershed, not just its city limits.
