The Morton Arboretum paving project has been a watershed for Advanced Pavement Technology (APT), Chuck Taylor's recently formed design/build firm in Oswego, Ill. An APT-certified contractor was the installer on this high-profile project. Pervious pavers were selected for their ecological advantages. Late last year, the nature conservators, the paver manufacturer, installer, and others hosted a symposium to acquaint architects and city and building officials with the system. Taylor believes this market has much growth potential.

And the industry seems poised for more growth, even with a strong overall paver market. Paver sales in North America totaled 615 million square feet in 2003, with the United States accounting for 530 million square feet. The market is growing at more than 8% annually.
