The Easy Street case study shows 3.5-foot porous
concrete paver block strips on either side of an
18-foot conventionally paved surface. The paver
blocks can easily be lifted off their subbase in order
to reach water pipes beneath the street. In addition,
in the driver’s eye these strips make the street look
narrower, even though the pavers can handle the
same loads as the asphalt. This perception of a
narrower street has resulted in significantly slower
speeds through what once was a “cut-through”
street.
• Take advantage of planted areas surrounded
by impervious surfaces. For instance, cul-de-sac
interior circles and boulevard medians are typically
planted areas. These areas are usually mounded
at or above the road surface (convex topography).
These areas could just as easily be depressions
(concave topography) that capture drainage from
the road, either over ribbon curb or through curb
cuts in mountable or standard curb around the
island or boulevard.
The Pokagonek Edawat Housing Development located in
Dowagiac, MI includes the use of 25,000 square feet of
interlocking pavers for the primary driving surface.
