THE DRY GARDEN: HARVESTING RAINNovember 11, 2009 | By Emily Green
“It stands to reason that some of the most progressive environmentalists in Los Angeles work for the Department of Public Works’ Bureau of Sanitation. They are the front line between what we discard and the environment.”
Treats Polluted Urban Runoff:
Nearly 40% of the county’s
needs for cleaning polluted
runoff could be met by LID
projects on existing public
lands.

Energy Use & Climate Change:
Greater reliance on local water
supply instead of pumping from
distant locations would save
72,000—233,500 MWH of
energy per year.
