Westmoreland StreetWestmoreland Street, Portland, OR

In November of 2004, a pilot project to install Ecoloc® permeable interlocking concrete pavement (PICP) in the 80-year old Westmoreland neighborhood was undertaken as part of a joint project by the Portland Office of Transportation, Bureau of Environmental Services, and the Portland Water Bureau.


The project will test how well PICP performs on a public residential street and will provide data on durability, drainage capabilities of the Ecoloc pavement, and maintenance requirements.

Jordan Cove Glen Brook GreenJordan Cove Glen Brook Green Waterford, CT

This project is part of the EPA's Section 319 National Monitoring Program that addresses non-point source pollution. It was the first NMP project in the country to study the impact of residential development on stormwater runoff quantity and quality, as well as management practices used to manage the runoff. The neighborhood utilizes a number of BMP practices including grass swales, vegetated bio-retention areas, roof leader rain gardens, street sweeping, and fertilizer and pesticide management. The project's cul-de-sac, reduced-width street and some of the driveways are paved with permeable UNI Eco-Stone® pavers.

Morton Arboretum

Morton Arboretum, DuPage County, IL

The Morton Arboretum decided in the late 10090s to under take a large-scale redevelopment of their 1700-acre outdoor museum. The facility had received a grant from the Illinois Environmental Protection Agency's Clean Lakes Program for a complete renovation of Meadow Lake, which is adjacent to the visitor center and parking lot. An impervious parking area was deemed inappropriate for the low impact design parameters of the project and it was decided to construct a "green" parking lot that would incorporate a number of best management practices.
