parking lots vs climate. food. clean water
From suburban driveways to the sprawling lots that spring up
around big retailers, Americans devote lots of space to parking
spaces -- a growing land-use trend that plays a role in
heating up urban areas and adding to water pollution, according
to a recent study.
Purdue University researchers surveyed the total area devoted
to parking in a midsize Midwestern county and found that
parking spaces outnumbered resident drivers 3-to-1 and
outnumbered resident families 11-to-1. The researchers found
the total parking area to be larger than 1,000 football fields,
or covering more than two square miles.
Pijanowski said that his results are cause for concern, in
part, because parking lots present environmental and economic
problems. They are, for instance, a major source of water
pollution, he said.
Tippecanoe County parking lots turn out about 1,000 pounds of
heavy metal runoff annually, said Purdue professor Bernard
Engel, who used a computer model to estimate changes in water-
borne runoff caused by land-use changes. Engel, head of the
Department of Agricultural and Biological Engineering, said
lots are troublesome because pollutants collect on their non-
absorbent surfaces and are then easily carried away by rain.
Pijanowski counted 355,000 parking spaces in Tippecanoe County,
home to about 155,000 residents. Farmers could produce 250,000
bushels of corn in the same space taken up by county parking
lots, he said.

- 3 spaces per registered driver is low. I expect its 4 or more. The
researcher noted that he didn't count them all.
Land use codes in the county probably dictate the provision of most of
As NYC mostly predated minimum parking requirements it hasn't suffered
under their burden.
