Ben Haggard (ReGenesis Design) and partners in Santa Fe have done a
number of parking lots that, although compromised by code restrictions
and the engineering mentality (Water is your enemy! Banish it to the
ocean!), work pretty well. They are asphalt, laid out more or less on
contour, and have parking-space-sized slots and other well-planted
interruptions in the pavement to intercept runoff and allow it to
percolate (think "series of small swales"). The engineers have forced
them to put drains in them too, but even in big storms, water rarely
makes it to the drains, or so Ben told me. The plantings probably help
filter out petroleum pollutants too. You might be able to design some
of the swales so that snow from plowing could be piled onto them to
melt. They get some snow in Santa Fe, but not as much as Organic Valley
does.
Anyone have any
experience in a northern clime with something other than gravel,
asphalt, & these permeable tiles which shift around & would make it
hard for snow plowing?
