Permeable Paving
GrassPave Permeable Paving
Permeable paving, unlike standard asphalt or concrete, holds rainwater underground and on-site, instead of sheeting off the surface and contaminating Indian Creek. Planted in 2009, the grass reduces the heat-island affect while providing structure for vehicles and pedestrians. Our GrassPave permeable paving is located outside the east side of the barn and between prairie gate bridge and the suspension bridge south of the building.
Grasspave2 fulfills the same function as asphalt by providing a load-bearing, sturdy structure for people to walk on or drive on. It provides the aesthetics of grass, does not heat up the way asphalt does, and, like other permeable paving systems, holds rainwater in a gravel bed underneath the surface. The water retention allows the rainwater to percolate slowly into the surrounding surface over time, allowing contaminants to settle out and reduces fast-moving surface water that scours out rivers and creeks and contributes to flooding. The Nature Center selected Grasspave2 from the Coleman Moore Company in part because it is fairly simple to install. It was installed in partnership with Metro High School students.
Permeable Concrete
Permeable concrete fulfills the same function as standard concrete by providing a load-bearing, sturdy structure for people to walk or drive on. The large size of the limestone chips in the concrete allow water to percolate downward, into a gravel bed underneath the concrete, where the water is held. Installed at the Nature Center in 2010 by Eggleston Concrete, our permeable concrete welcomes visitors on the front walk to the building. King’s Masonry and Landscape can also provide permeable pavers that provide load-bearing capability while significantly reducing runoff associated with traditional hard surfaces.
