Urbanism Principles


PRINCIPLES OF URBANISM


The principles of urbanism can be applied increasingly to projects at the full range of scales from a single building to an entire community.


1. Walkability

-Most things within a 10-minute walk of home and work

-Pedestrian friendly street design (buildings close to street; porches, windows & doors; tree-lined streets; on street parking; hidden parking lots; garages in rear lane; narrow, slow speed streets)

-Pedestrian streets free of cars in special cases


2. Connectivity

-Interconnected street grid network disperses traffic & eases walking

-A hierarchy of narrow streets, boulevards, and alleys

-High quality pedestrian network and public realm makes walking pleasurable


3. Mixed-Use & Diversity

-A mix of shops, offices, apartments, and homes on site. Mixed-use within neighborhoods, within blocks, and within buildings

-Diversity of people - of ages, income levels, cultures, and races


4. Mixed Housing

A range of types, sizes and prices in closer proximity


5. Quality Architecture & Urban Design

Emphasis on beauty, aesthetics, human comfort, and creating a sense of place; Special placement of civic uses and sites within community. Human scale architecture & beautiful surroundings nourish the human spirit


6. Traditional Neighborhood Structure

-Discernable center and edge

-Public space at center

-Importance of quality public realm; public open space designed as civic art

-Contains a range of uses and densities within 10-minute walk

-Transect planning: Highest densities at town center; progressively less dense towards the edge. The transect is an analytical system that conceptualizes mutually reinforcing elements, creating a series of specific natural habitats and/or urban lifestyle settings. The Transect integrates environmental methodology for habitat assessment with zoning methodology for community design. The professional boundary between the natural and man-made disappears, enabling environmentalists to assess the

design of the human habitat and the urbanists to support the viability of nature. This urban-to-rural transect hierarchy has appropriate building and street types for each area along the continuum.


7. Increased Density

-More buildings, residences, shops, and services closer together for ease of walking, to enable a more efficient use of services and resources, and to create a more convenient, enjoyable place to live.

-New Urbanism design principles are applied at the full range of densities from small towns, to large cities


8. Green Transportation

-A network of high-quality trains connecting cities, towns, and neighborhoods together

-Pedestrian-friendly design that encourages a greater use of bicycles, rollerblades, scooters, and walking as daily transportation


9. Sustainability

-Minimal environmental impact of development and its operations

-Eco-friendly technologies, respect for ecology and value of natural systems

-Energy efficiency

-Less use of finite fuels

-More local production

-More walking, less driving


10. Quality of Life

Taken together these add up to a high quality of life well worth living, and create places that enrich, uplift, and inspire the human spirit.



BENEFITS OF URBANISM


1. BENEFITS TO RESIDENTS

Higher quality of life; Better places to live, work, & play; Higher, more stable property values; Less traffic congestion & less driving; Healthier lifestyle with more walking, and less stress; Close proximity to main street retail & services; Close proximity to bike trails, parks, and nature; Pedestrian friendly communities offer more opportunities to get to know others in the neighborhood and town, resulting in meaningful relationships with more people, and a friendlier town; More freedom and independence to children, elderly, and the poor in being able to get to jobs, recreation, and services without the need for a car or someone to drive them; Great savings to residents and school boards in reduced busing costs from children being able to walk or bicycle to neighborhood schools; More diversity and smaller, unique shops and services with local owners who are involved in community; Big savings by driving less, and owning less cars; Less ugly, congested sprawl to deal with daily; Better sense of place and community identity with more unique architecture; More open space to enjoy that will remain open space; More efficient use of tax money with less spent on spread out utilities and roads


2. BENEFITS TO BUSINESSES

Increased sales due to more foot traffic & people spending less on cars and gas; More profits due to spending less on advertising and large signs; Better lifestyle by living above shop in live-work units - saves the stressful & costly commute; Economies of scale in marketing due to close proximity and cooperation with other local businesses; Smaller spaces promote small local business incubation; Lower rents due to smaller spaces & smaller parking lots; Healthier lifestyle due to more walking and being near healthier restaurants; More community involvement from being part of community and knowing residents


3. BENEFITS TO DEVELOPERS

More income potential from higher density mixed-use projects due to more leasable square footage, more sales per square foot, and higher property values and selling prices; Faster approvals in communities that have adopted smart growth principles resulting in cost / time savings; Cost savings in parking facilities in mixed-use properties due to sharing of spaces throughout the day and night, resulting in less duplication in providing parking; Less need for parking facilities due to mix of residences and commercial uses within walking distance of each other; Less impact on roads / traffic, which can result in lower impact fees; Lower cost of utilities due to compact nature of New Urbanist design; Greater acceptance by the public and less resistance from NIMBYS; Faster sell out due to greater acceptance by consumers from a wider product range resulting in wider market share


4. BENEFITS TO MUNICIPALITIES

Stable, appreciating tax base; Less spent per capita on infrastructure and utilities than typical suburban development due to compact, high-density nature of projects; Increased tax base due to more buildings packed into a tighter area; Less traffic congestion due to walkability of design; Less crime and less spent on policing due to the presence of more people day and night; Less resistance from community; Better overall community image and sense of place; Less incentive to sprawl when urban core area is desirable; Easy to install transit where it's not, and improve it where it is; Greater civic involvement of population leads to better governance




WAYS TO IMPLEMENT NEW URBANISM


The most effective way to implement New Urbanism is to plan for it, and write it into zoning and development codes. This directs all future development into this form.

New Urbanism is best planned at all levels of development:


-The single building

-Groups of buildings

-The urban block

-The neighborhood

-Networks of neighborhoods

-Towns

-Cities

-Regions


Increasingly, regional planning techniques are being used to control and shape growth into compact, high-density, mixed-use neighborhoods, villages, towns, and cities. Planning new train systems (instead of more roads) delivers the best results when designed in harmony with regional land planning - known as Transit Oriented Development (TOD). At the same time, the revitalization of urban areas directs and encourages infill development back into city centers.


Planning for compact growth, rather than letting it sprawl out, has the potential to greatly increase the quality of the environment. It also prevents congestion problems and the environmental degradation normally associated with growth.


OBSTACLES TO OVERCOME


The most important obstacle to overcome is the restrictive and incorrect zoning codes currently in force in most municipalities. Current codes do not allow New Urbanism to be built, but do allow sprawl. Adopting a TND ordinance and/or a system of 'smart codes' allows New Urbanism to be built easily without having to rewrite existing codes.


An equally important obstacle is the continuous road building and expansion taking place in every community across America. This encourages more driving and more sprawl which has a domino effect increasing traffic congestion across the region. Halting road projects and building new train systems helps reverse this problematic trend. Read more



"Only when humans are again permitted to build authentic urbanism — those cities, towns, and villages that nurture us by their comforts and delights — will we cease the despoiling of Nature by escaping to sprawl" -Andres Duany
