In a best-practices installation, rainwater enters the voids and is collected in layers of aggregate underneath. From there it is absorbed into the ground, where it is naturally filtered, or is collected into an outflow pipe or other disposal means. StormPave came with one additional benefit: It was a good fit for the neighborhood. "As the proposed development is intending to emulate the historic character of this District, the design team and owner determined the best aesthetic solution to achieving this is through the use of clay pavers," said Hinte. A COMEBACK ON THE CUYAHOGA More than four decades after the fire, the Cuyahoga is showing signs of life again. At about the same time that the latest phase of Flats East Bank was opened, researchers on the Cuyahoga found a walleye 10 miles south of Lake Erie, according to the Cleveland Plain Dealer. The walleye, which was among smallmouth bass, yellow and white perch, bluegills and catfish, is a good sign that the lake is coming back to life. Environmentalists are building fish habitats to help the process along, as the presence of healthy fish and other aquatic life is seen as a good sign that the river is well on its way to recovery. But what's needed is a way for more water to get into the soil, which will mean more trees, better shade, and cleaner water throughout the watershed that leads into the Cuyahoga, according to Jane Goodman, executive director of Cuyahoga River Restoration, which is the group charged with the responsibility of overseeing the river's cleanup. Goodman said that permeable pavers address impervious surface area. Stormwater and septic sewer overflows during rainstorms have historically prompted frequent beach closures. The solution would be to slow the flow of stormwater, which would effectively ease the burden from sewage treatment plants. Putting in rain gardens on lawns and bioswales on commercial parking lots do help somewhat, but what's needed is to find a way to treat larger volumes of stormwater by removing solid surfaces entirely. "In order to really recover the water quality, we will need to replace impervious surfaces with permeable surfaces, which is why we love permeable paving," said Goodman. "The fact that permeable pavers sit on top of temporary storage vaults means that more stays there to filter down through the soil. And the fact that these are put in adjacent to impervious surfaces is a really important factor in making permeable paving so attractive, so useful and so effective." Walt Steele is a recognized expert on clay pavers. He is paver business manager for Pine Hall Brick Company, America's largest manufacturer of genuine clay pavers. The company has plants in Madison, NC and Fairmount, GA. Its corporate headquarters is at 2701 Shorefair Drive NW, Winston-Salem, NC 27105.

Tumbled clay pavers were specified in the streets and pedestrian plazas to match the character of decades-old brick roadways. Clay permeable pavers play center stage in a large pedestrian plaza that connects the riverfront to the main mixed-use building where festivals, street fairs and concerts are held. Paver accent bands bisect the plaza with a radial form that is centered on the riverwalk overlook. Truncated dome pavers and changes in color and pattern define a vehicular zone through the plaza for daytime driving and deliveries, but the flush installation prioritizes pedestrians as the primary users of the plaza. StormPave permeable clay pavers from Pine Hall Brick Company were chosen to address stormwater management requirements on the riverwalk. It's part of a national trend prompted by regulatory changes. Many cities — large and small — are requiring new commercial developments to treat their stormwater on site, rather than tying into overtaxed storm drains or allowing stormwater to discharge surface pollutants into a nearby river.
