new urbanism: theory, principles& its evolution
2017: DPZ Partners
Epidemic of sprawl development patterns: USA
• Areas dominated by single-use• Car dependence• Excessive automotive traffic• Lack of transportation alternatives• Lack of useable open space• Excessive land consumption• Degraded wilderness & habitat• Increased air pollution• Increased burden on municipal
infrastructure• Diminished quality of life
2017: DPZ Partners
2 patterns of development since beginning of time
Complete Community: Walkable Urbanism
(up to 1940’s)
Fragmented Development: Drivable Sprawl(since 1940’s)
+600 new cities, of 10 million each estimated to be built over next century to accommodate new urban dwellers.

The Theory of New Urbanism
2017: DPZ Partners
Seaside: renaissance of place, 1980
• Achieve and restore time-tested forms of urbanism
• Provide vitality, walkability and economic resilience to our towns and cities
• Preserve natural environment and cultural heritage of areas.

13-pt Checklist of NU1. The Neighborhood has a discernible center.
This is often a square or green, and sometimes a busy or memorable street intersection. A transit stop would be located at this center.
2017: DPZ Partners
13-pt Checklist of NU2. Most of the dwellings are within a five minute walk of the center.
This distance averages one quarter of a mile.
2017: DPZ Partners
13-pt Checklist of NU3. There is a variety of dwelling types within the Neighborhood.
These usually take form of houses, rowhouses and apartments, such that younger and older people, singles and families, the poor and the wealthy, may find places to live.
2017: DPZ Partners
13-pt Checklist of NU4. There are shops and offices at the edge of the neighborhood.
The shops should be sufficiently varied to supply the weekly needs of a household. A convenience store is the most important among them.
2017: DPZ Partners
13-pt Checklist of NU5. A small ancillary building is permitted within the backyard of each house.
It may be used as one rental unit, or as a place to work.
2017: DPZ Partners
13-pt Checklist of NU6. There is an elementary school close enough so that most children can
walk from their dwelling This distance should not be more than 1.5 km.
• 1969: > 41% of children walked or biked to school• 2001: < 13% of children walked or biked to school
2017: DPZ Partners
13-pt Checklist of NU7. There are small playgrounds quite near every dwelling.
This distance should not be more than one eighth of a mile.
2017: DPZ Partners
13-pt Checklist of NU8. The streets within the neighborhood are a connected network.
This provides a variety of itineraries and disperses traffic congestion
ABC
A = vehicular & cycling streetB = parking street / courtC = pedestrian Street
2017: DPZ Partners
13-pt Checklist of NU9. The streets are relatively narrow and shaded by rows of trees.
This slows down the traffic, creating an environment for the pedestrian and the bicycle.
2017: DPZ Partners
13-pt Checklist of NU10. Buildings at the neighborhood center are placed close to the street.
This creates a strong sense of place.
2017: DPZ Partners
13-pt Checklist of NU11. Parking lots and garage doors rarely front the streets.
Parking is relegated to the rear of buildings, usually accessed by alleys.
2017: DPZ Partners
13-pt Checklist of NU12. Certain prominent sites are reserved for civic buildings.
Buildings for meeting, education, religion or culture are located at the termination of street vistas or at the Neighborhood center.
2017: DPZ Partners
13-pt Checklist of NU13. The Neighborhood is organized to be self-governing.
A formal association debates and decides on matters of maintenance, security and physical change (but not on taxation which should be the responsibility of the larger community).

Smart Growth Principles
1. Create range of housing 2. Create walkable neighborhoods 3. Encourage community and stakeholder collaboration 4. Foster communities’ sense of place 5. Make development decisions predictable and fair 6. Mix land uses 7. Preserve open space, farmland, natural beauty, critical environmental areas 8. Provide transportation choices 9. Develop existing communities first 10. Encourage compact building design

Congress for New Urbanism (CNU)
“We stand for the restoration of existing urban centers and towns within coherent metropolitan regions, the reconfiguration of sprawling suburbs into communities of real neighborhoods and diverse districts, the conservation of natural environments, and the
preservation of our built legacy.”

Principles of NU: 4 scales

Designing Sustainable Communities
Smart Locations & Linkages Neighborhood Pattern & Design Green Infrastructure & Buildings
• Include transportation energy intensity of buildings into total building’s performance.
• Any green rating system must consider context and pattern of settlement.

Sprawl & Health

Need policies that produce walkable urbanism:• reduce exposure to toxins and pollutants;• minimize environmental impact; • encourage a healthy life-style; and• makes people happier!

Economic Success of Smart Growth
“Smart Growth development generates 10 times more tax revenue per acre than conventional suburban development.”

Social Equity: tangibles & intangibles
People in more compact, connected places are:
• Happier• Safer• Live longer• Have greater upwards mobility

Paradigm of Scientific Planning
• Provides for an effective framework for implementation.
• The TRANSECT as a SCIENTIFIC TOOL, for classifying sustainable urban development patterns.
• Calibrated to LOCAL CONTEXT.
