Can save $10 million in annual energy costs each year in Los Angeles. By planting four trees at your home, you can save up to 30% on summer cooling costs.
Can remove 2,240,000 pounds of air pollutants annually in Los Angeles, and save $23 mil l ion per year in air pollut ion clean up costs.
Can capture 1,925,000,000 gallons of stormwater per year, which decreases both polluted runoff and soil and hill erosion and would save $5 mil l ion in annual storm-water runoff costs.
One million trees…
“I t’s good to know about trees. Just remember
nobody ever made any big
money knowing about trees.”
“Nature should provide the order and
underlying structure of the metropolis”.
- P. Calthrope
Infrastructure – the substructure or
underlying foundation… on which the
continuance and growth of a community or
state depends.
– Webster's New World Dictionary
Green infrastructure is our natural life support
system- an interconnected net work of waterways,
wetlands, woodlands, wildlife habitats, and other
natural areas; greenways , parks and other
conversation lands; working farms, ranches and
forests; and wilderness and other open spaces that
support native species, maintain natural ecologic
processes, sustain air and water resources and
contribute to to the health and qualities of life or
Americas communities and people.
Green Infrastructure –
The network of open spaces in and around
cities designed to enhance local economic
vitality, sustain natural systems, connect
people to the natural world, and increase
individual and community well being.
“A connected system of parks and
parkways is manifestly far more complete
and useful than a series of isolated
parks.”
- Fredrick Law Olmsted, 1903

each place, expressing it in the design of
communities, integrating it within our
towns, and respecting its balance are
essential ingredients of making the human
place sustainable and spiritually
nourishing.”- P. Calthorpe.
Physically connected green spaces maintain ecological processes, wildlife populations and human health.

A settling pond helps cleanse runoff before it flows into Willamette River
Bioswale cleanses stormwater runoff from
the parking lots and roof of the Wal-Mart in
McKinney, TX
Stormwater flows through a biotope to cistern and back to top of stream
Rain garden uses bioretention to treat stormwater runoff
Swales receive all runoff from the parking
lot and use it for irrigation
Biopaver contains a phytoremediating plants that
filter pollutants from stormwater runoff.
“We abuse the land because we regard it
as a commodity belonging to us. When
we see land as community to which we
belong, we may begin to use it with love
and respect…conservation is a state of
harmony between men and land.”
- Aldo Leopold, 1949
“Man’s mind, once stretched by a
new idea, never regains its
original dimensions.”

“To live fully is to be engaged in the
passions of one’s time.”
- Oliver Wendell Holmes
Preserving our desert heritage
while creating a great desert city
are two sides of an inseparable
quest. The choice before us is to
excel in both or end up with
neither.
“To live fully is to be engaged in
the passions of one’s time.”
- Oliver Wendell Holmes
Hey how are you doing? Scottsdale is already a "Tree City USA". I agree with you. We just need to find away to water them consistantly (sic) with non-potable water.Say hi to Vern.Tony
Thank you, Mark! I agree, the more trees the better.
