=v= I would hope so, but the panhandle path in San Francisco's
Golden Gate Park has been doing the opposite for as long as
anyone can remember (three decades, at least). They waste a
lot of water on paths, spraying riders and amblers, despite
longstanding drought conditions.
=v= Last year they tested a new Irritation System (in the
middle of the day, naturally):
It didn't change a thing.
=v= There are efforts towards permeable surfaces in some cities,
since so much concrete and asphalt keeps rainwater from the
aquifers and diverts them into overtaxed sewage systems. In
some cases this means special paving blocks that water soaks
into (until they're blocked with gunk), and in other cases
it means breaking up concrete and putting in landscaping.
=v= Not to harp on the foolishness of San Francisco's city
government again, but in some cases they're doing this on
too-narrow sidewalks, where a landscaped bulbout or would
be far more appropriate:
It's pretty frustrating when good ideas get implemented in
a way that ruins other good ideas!
