Maintenance Supervisor Wendie Butler of Sublette County, Wyo., decided the stormwater management and runoff filtration benefits of pervious pavers would be a good fit for the county's needs, and selected Xeripave® SP Pavers for a variety of projects.

The SP Paver has an infiltration rate exceeding one gallon per second per square foot; enough to successfully manage runoff while only covering 12 to 18 percent of a project's total surface area. When impervious surfaces like standard concrete or asphalt cover most of a project area, stormwater can be directed from the impervious surfaces to the pervious pavers, filtering the water into the soil below and providing a cost effective stormwater management solution.

Sublette County's first pervious addition was two eight-foot strips of pavers for drainage under a gas meter, where the hardscaped area was originally composed of asphalt and cement. Butler was impressed by the pavers' ease of installation and maintenance, and moved on to a larger, higher-profile project.

The county was having difficulty maintaining an area hardscaped with river rock at the circuit court building. A rock sealant was added, but brought high maintenance fees due to cleaning difficulties. Looking for an alternative approach, Butler replaced the river rock with SP Pavers. Maintenance costs dropped, and the pavers provided the natural look county officials were searching for.
