Gilbert’s 1909 plan to connect the train stationand
downtown
myth       [mith]

any invented story, idea, or concept:




sacred cow
an
individual, organization, institution, etc., co
nsidered to be exempt from criticism or
questioning.
Myth 1
Traditional Cities are
Obsolete
Le Corbusier‟s
                                                               Plan Voisin for Paris
                                                                      c1925




                     “In the age of the automobile and the skyscraper,
     the corridor street had become a „dead organ‟ incapable of fulfilling its function.

 In the Plan Voisin, Le Corbusier analyzed this function into two parts, transportation and
                                        sociability,
and created two new urban forms to deal with them: superhighways and pedestrian malls.”

The Housing Act
    of 1949
“Our success as a country
 and as a species utterly
depends on the health and
  wealth of the cities.”
“America‟s poor treatment
 of its own cities over the
  past half century helps
 spawn many of out most
    dire problems, from
  increased inequality to
 environmental damage to
   the recent economic
         collapse.”
Myth 2
Networks are no longer
important

Cities with a fine grained network of small streets were
 much safer and also had more walking and biking

                         Cities




                   For example, Network of
                       Neighborhoods
Myth 3
Good Transportation is
Fast Transportation
Sixty years ago, Lewis Mumford reminded us that the exact
        opposite of this myth was true when he said


“A good transportation system minimizes
      unnecessary transportation”
What is Transportation for?
 The purpose of transportation is to
provide access to goods and people

Speed Kills Urbanism
Streetcars: Great Access – Great Urban Compatibility
Speedier Travel, not Faster Vehicles

 This does not mean that we should never try to speed up
travel, but any increase in speed should be done in a way
   that is compatible with the character of urban places

 In Zurich, faster transit is achieved by giving the transit
                    priority in many ways
Myth 4
Traffic is always growing and
we must accommodate it or
the city will come to a halt
Predict and Provide
Street and Highway Capacity




       “With projections indicating fifty thousand cars by
       1960, Moot (chair of the City Planning Commission)
      projected a need for fourteen thousand new (parking)
                             spaces.”
Minimum Parking Standards
 Most cities require that a minimum amount of parking must be
added for each 1000 sq. ft. of new development or each new job
                            or resident
Sufficient Parking a Must!

                    „With projection indicating fifty thousand cars by 1960, Moot
                    (chair of the City Planning Commission) projected a need for
                               fourteen thousand new (parking) spaces.

                  Mayor Joseph Mruk agreed. Not only would the city build three
                     parking ramps (garages), it would encourage the private
                  development of parking facilities downtown “by assisting in
                    the condemnation and assembly of necessary sites.”
                   The campaign to build parking spaces for twenty-five thousand
                                   automobiles began in 1950.‟




“The most critical improvement to [neighborhood shopping districts] which could
   be made at this time is the provision of off-street parking facilities” (City of
                                  Harford, 1972).

Transportation Matters!




The goal of the modernist was to create cities that worked for cars.
We embraced this philosophy in Connecticut, and it failed abysmally
Some Places Developed Transportation
              Systems that Serve the City, Not the Other
                            Way Around

Planning in an Auto-Oriented World
Streetcars and Freeway Removal

1. What are the strategic long term goals of the city?
2. Does a particular project advance or hinder these
   goals?
3. How does the project strengthen vital networks in the
   city (street, transit, neighborhood, regional networks?
4. Does the project help reduce the city’s environmental
   footprint?
5. Does the project reduce the long term economic
   burden for travelers in the city?
6. Does the project make the city more attractive and vital
   over the long run?

  • 56. Speedier Travel, not Faster Vehicles This does not mean that we should never try to speed up travel, but any increase in speed should be done in a way that is compatible with the character of urban places In Zurich, faster transit is achieved by giving the transit priority in many ways
  • 57. Myth 4 Traffic is always growing and we must accommodate it or the city will come to a halt
  • 58. Predict and Provide Street and Highway Capacity “With projections indicating fifty thousand cars by 1960, Moot (chair of the City Planning Commission) projected a need for fourteen thousand new (parking) spaces.”
  • 59. Minimum Parking Standards Most cities require that a minimum amount of parking must be added for each 1000 sq. ft. of new development or each new job or resident
  • 60. Sufficient Parking a Must! „With projection indicating fifty thousand cars by 1960, Moot (chair of the City Planning Commission) projected a need for fourteen thousand new (parking) spaces. Mayor Joseph Mruk agreed. Not only would the city build three parking ramps (garages), it would encourage the private development of parking facilities downtown “by assisting in the condemnation and assembly of necessary sites.” The campaign to build parking spaces for twenty-five thousand automobiles began in 1950.‟ “The most critical improvement to [neighborhood shopping districts] which could be made at this time is the provision of off-street parking facilities” (City of Harford, 1972).

Editor's Notes

  1. Why I am here…. I believe that what happens in New Haven is key to the future of ConnecticutNew Haven is crucial in many ways – Furthest along in terms of restoring urban life of any ConnecticutAnd there are many to credit including the City Government, the Universities and many of you here in this roomBut observing NH over the last several years what I see is a series of fits and starts – lots of good things but also some mis-stepsWe are here today to discuss how we can take better advantage of some incredible opportunities for moving the city forwardThe Streetcar and Downtown Crossing???? Are not just transportation projects but must be seen as opportunities to heal the scares of past planning disasters
