How We Got Into this Mess, and Our Way Out
3. How do we take the principles
of active living, combine them
with active transportation and
expand our ideas and concepts
to achieve a fully sustainable
world?
Have we reached
the precipice yet?
4. How do we take the principles
of active living, combine them
with active transportation and
expand our ideas and concepts
to achieve a fully sustainable
world?
Simple: by waking up, then
using our heads, our heart and
our feet. The question is will
we do this just in the nick of
time? Or not?
5. Is this the landscape we want to leave
our children?
15. The Pedestrian in America has been
marginalized compromised to Death
16. Thirty percent of North Americans old enough to
drive do not drive. This percentage is increasing.
17. Choosing a Preferred Alternative
Scenario A: Low Density Scenario B: Baseline
Scenario C: Walkable Neighborhoods Scenario D: High Infill
18. If you come to a fork in the road, take it.” … Yogi Berra
19. If you want to build a ship. Don’t drum up people
to collect wood and don’t assign them tasks and
work, but rather teach them to long for the
endless immensity of the sea”
— Antoine de Saint-Exupery
27. Driving more miles each
year (like obesity) is a
visible symptom, an
indicator of a disease
that is running amuck in
each of our towns and
villages.

Where are the parks?
Where are the trails?
Where is the public
realm?
Where do people gather?
How do you go place to

Where do you buy a

33. "If we are to have full use of
automobiles, cities must be
remade...awaiting industry that will do
wonders, for prosperity will spring up
when we revamp our cities”
…Post Magazine (circa 1930)
34. “Abundant sunshine, fresh air, fine
green parkways will blend together
seamlessly with dazzling
skyscrapers and seven-lane
highways.”

traffic problem in Los Angeles…

presence is the only solution to our
traffic problems…

37. “A driveable future. An auto company
has a new design competition to imagine
a future city that is car-friendly”
(June 28, 2010)
38. “Automobiles are often conveniently tagged as the villains
responsible for the ills of cities and the disappointments and futilities
of city planning. But the destructive effects of automobiles are much
less a cause than a symptom of our incompetence at city building.
The simple needs of automobiles are more easily
understood and satisfied than the complex needs of cities,
and a growing number of planners and designers have
come to believe that if they can only solve the problems of
traffic, they will thereby have solved the major problems
of cities.
Cities have much more intricate economic and social concerns than
automobile traffic. How can you know what to try with traffic until
you know how the city itself works, and what else it needs to do with
its streets? You can't.”
Jane Jacobs, Death and Life of Great American Cities , 1961
“How can you know what to try with traffic until
….”

45. “What is the first thing an
infant wants to do and the
last thing an older person
wants to give up?”
46. A walkability plan must set a stage for
all other modes of transportation to
work, including transit. If people
cannot walk then transit remains
ineffective.
“What is the first thing an
infant wants to do and the
last thing an older person
wants to give up?”
Walking is the exercise
that does not need a gym. It is
the prescription without
medicine, the weight control
without diet, and the cosmetic
that can’t be found in a chemist.
It is the tranquilizer without a
pill, the therapy without a
psychoanalyst, and the holiday
that does not cost a penny.
What’s more, it does not pollute,
consumes few natural resources
and is highly efficient. Walking is
convenient, it needs no special
equipment, is self-regulating and
inherently safe.
.”
47. Vehicle miles traveled (VMT) around the U.S. have increased by 70
percent over the last 20 years, compared with a two percent increase in
new highway construction. The U.S. General Accounting Office
predicts that road congestion in the U.S. will triple in 15 years even if
capacity is increased by 20 percent.
Traffic is growing about five times faster than the growth in population.
(Data compiled for a report to the U.S. Department of Transportation
in 2006 written by Stephen Polzin, (transportation researcher at the
University of South Florida in Tampa.)
Why we cannot
build our way out
of traffic
48. The World is
Changing
Expect:
Option One:
25% more traffic every ten years.
More intersections failing.
More people spreading out into
canyons, ridges and other high
risk locations.
Also Expect:
More cars per household
Limited new lanes and limits on
intersections being rebuilt
More demand for slowing traffic
More demand for traffic to stay in motion
More demand for safer streets
More demand for quieter streets
49. Option Two:
Return to Traditional
streets and land uses
More connectivity
More walking, bicycling and
transit
People living closer to services,
shorter trips by time and
distance
More funding for well located
engine houses
Improved and more appropriate
equipment
More ways to respond
Fewer personal injury auto
crashes
50. The simple needs of
automobiles are
more easily
understood and
satisfied than the
complex needs of
cities, and a growing
number of planners
and designers have
come to believe that
if they can only solve
the problems of
traffic, they will
thereby have solved
the major problems
of cities.
Following that
philosophy led to
this, redundantly.
A new beaker and
measure will lead to
this.

52. New measure for street performance:
People come to your street to shoot their wedding pictures
53. "If we want a booming economy of mom and pop stores, we'd
better build the environment where they succeed”

55. Build Villages, Not
Traffic

Form, Right Scale,
Right Density
• Circulation System and
Connectivity
• Focus on Access, not
Mobility.
• Seamless switching

Sustainable Future
77. If Cities are to reduce
auto-dependence a
working alternative
should include:
Developers no longer
block access to those
places people want to
reach.
86. Based on the 1928 drawings by James Perry
The intensity of
uses should
gravitate away
from the
neighborhood
center
Townhouses frame the square while open
space provides an outdoor environment for
nearby residents
The largest lots of
the TND can be at
the edge
In these cases where
a TND is bordered by a
principal street higher
intensity uses such as
medium density
housing can be used in
creating the edge
Civic buildings
Should be
terminate street or
open space vistas
87. Personal choices of where to sit or recreate are not accidental.
Balance of sun and shade are determinant in active and passive
activities. In warm climates like Florida, shade is a critical asset to
the comfortable year round use of a space.
Why are these the only three empty tables at this
restaurant?
Why did this person choose this spot?
90. Make blocks a
walkable size:
block perimeters of
1,500’ to 2,000’
create a connected
network of streets
91. Design for a mix
of land uses:
Centers include
denser housing, a
square, civic uses,
and neighborhood-
oriented retail.

120. The Illustrative Plan (above) is the result of this planning process; it shows the
hypothetical buildout of the corridor, locating building footprints (new
and existing), open space, and parking areas. The corridor was divided into four
study areas, the Western Gateway, the Neighborhood Center, the Village Center,
and the Town Center. Each area has it’s own unique characteristics and challenges
which were addressed.
Quick sketches were done to study buildings that would result from the hypothetical
building footprints in the Illustrative Plan, combined with the proposed height limits
in the study areas and potential architectural regulations of the new code. each

153. TWO WOLVES
One evening an old Cherokee told his
grandson about a battle that goes on inside
people. He said, "My son, the battle is
between two wolves inside us all.
"One is Evil - It is anger, envy, jealousy,
sorrow, regret, greed, arrogance, self-pity,
guilt, resentment, inferiority, lies, false
pride, superiority, and ego.
"The other is Good - It is joy, peace, love,
hope, serenity, humility, kindness,
benevolence, empathy, generosity, truth,
compassion and faith."
The grandson thought about it for a minute
and then asked his grandfather: "Which
wolf wins?"
The old Cherokee simply replied,
"The one you feed."
