As part of the green component to the City of Aurora’s Long-Term Control Plan for CSO control, our firm and project partner, Hey and Associates, designed 112 individual rain gardens at 28 city intersections. This $1.7 million project is funded by the largest IEPA Illinois Green Infrastructure Grant to-date and relies on Aurora’s sandy soils to provide significant infiltration/volume control. Design considerations included multiple engineered soil mix pilots, porous pavement at two intersections, traffic operations design, ADA curb ramp upgrades, neighborhood-based landscape architecture restoration plans, provision for future performance monitoring, stormwater quantity and quality modeling, routine and non-routine rain garden maintenance, and integrated public informational meetings. The incorporation of green features into this project will result in an aesthetic amenity for the city.
