The
existing parking lot is paved with traditional curbing to direct
stormwater to the street and adjacent lawn area. The project goal
is to provide infiltration by utilizing various porous materials
as well as vegetative islands to manage and reduce stormwater
runoff.
Impervious
parking lots are a major generator of polluted runoff, particularly
in commercial and industrial areas. Working in partnership with
Weston Solutions, Inc., a leading environmental firm specializing
in redevelopment, the NEMO Program replaced two asphalt parking
stalls with permeable alternative surfaces that promote infiltration
of stormwater. After carefully preparing a subbase that included
processed stone, filter fabric and sand, concrete grid pavers
with an open lattice work structure were put into place. These
“gridders” were then finished in two different fashions:
one with gravel, and one with topsoil and grass seed.
