This chapter describes how to help create vibrant downtowns and business districts, and how this helps support TDM objectives.
Commercial Centers (also called Downtowns, Central
Business Districts, and
· Density and Clustering. Commercial centers should be medium- to high-density, with multi-story buildings. Densities of 50 employees or more per gross acre are desirable. As much as possible the ground floor of buildings should have activities and services that involve frequent public interaction (such as retail, professional services, civic offices, etc.), with office or residential activities above, which creates an attractive street environment while accommodating dense employment.
· Diversity. Centers contain a diverse mix of office and retail space, banks and law offices, public institutions (such as city hall, courthouses, and other government offices), entertainment and arts activities, and other suitable industries. Increasingly, commercial centers also have residential buildings, either within or nearby.
· Local and Regional Importance. Commercial Centers should contain a significant portion of total regional employment and business activity.
· Walkability. Most Commercial Centers are less than 250 acres in size so all destinations are within about 10-minute walk, with good sidewalks and pathways, pedestrian shortcuts, attractive Streetscapes, pedestrian scale and orientation, relatively narrow streets (4 lanes or less is desirable), relatively slow vehicle traffic (30 miles-per-hour or less is desirable), Universal Design, and a high degree of pedestrian Security. Some have Pedways, which are indoor walking networks that connect buildings and transportation terminals.
· Transportation Diversity. The area should be accessible by walking, cycling, taxi, automobile, and public transit.
· Parking Management. In order to avoid the need to devote a large portion of land to parking, Commercial Centers require that parking be managed for efficiency (Manfille and Shoup, 2004). It is often appropriate to use structured or underground parking, and to limit the total amount of parking in a commercial center.
· Transit Oriented Development. This refers to districts designed with features that facilitate transit accessibility, with maximum developing within convenient walking distance of Attractive Transit Stations.
There are many types of Commercial Centers, ranging from Downtowns (also called Central Business Districts or CBDs), which are the primary Commercial Center serving a region, to Secondary Business Districts and Village Centers. A large Central Business District can contain thousands of businesses with tens of thousands of employees, while a local village center may be considered successful if it has a dozen businesses with two or three hundred employees. Some have a particular base or specialty, such as a cluster of medical facilities, a wholesale district, a tourist district, or an adjacent university campus, but such centers include a diverse range of businesses providing support services.
Business activities tend to be more efficient in a
Strong Commercial Centers are an important component of Smart Growth and New Urbanism. Many central business districts and nearby neighborhoods are experiencing new residential development in the form of high- and medium-density condominiums and apartments, townhouses, and small-lot single-family homes. Urban living is particularly popular among young adults and retirees. Market surveys indicate that about a third of home buyers would prefer to live in mixed-use new urbanist community if available (Hirschhorn, 2001). Some central business districts are still losing business and population, but there are numerous indications that, with proper support, downtowns can be successful and provide numerous economic, social and environmental benefits.
Transportation planning decisions have significant impacts on the success of Commercial Centers. Walking, Public Transit and Parking Management are particularly important, and Commute Trip Reduction programs tend to be particularly effective. Public Bike Systems increase the convenience of cycling in downtown areas.
People who work, shop and live in a
Commercial Centers are an alternative to more Automobile Dependent commercial land use patterns, such as suburban strips (activities are scattered along major arterials, which requires a car trip between each destination), and private malls or campuses (which have a high degree of internal walkability, but are generally surrounded by large parking facilities, are widely dispersed, and contain a limited range of activities, and so tend to require numerous automobile trips).
Downtown
Development Evaluation (Jacobs, 2008):
There are many ways that public policies can encourage businesses to locate in commercial centers, and support their economic development (Smart Growth Policy Reforms).
· Governments can locate their own offices and services in suitable Commercial Centers.
· Zoning codes can encourage or require businesses (particularly large employers) to locate in suitable commercial centers and discourage strip commercial development.
· Tax policies and utility fees can favor the location of businesses in commercial centers.
· Infrastructure investments (roads, walking facilities, utilities, transit services) can favor commercial centers, particularly for industries that have numerous employees.
· Improve marketing efforts in Commercial Centers, for example, by sponsoring special events and coordinated advertising among businesses.
· Transportation policies and planning can favor multi-modalism, including walking, cycling and transit services. Walking and Cycling improvements are important in Commercial Centers.
· Parking Management tends to be particularly important in Commercial Centers.
· Transit Oriented Development often provides a catalyst for the development of Commercial Centers.
· Encourage infill development.
· Suburban malls can be converted into more mixed-use Commercial Centers by adding employment and residential land uses, improving pedestrian connections with nearby destinations, and expanding the range of services and activities available.
· Locate major organizations, such as universities and industrial centers, either within or near existing commercial centers.
Residents living in or near
Commercial Centers tend to own fewer cars than residents of more dispersed,
isolated areas (Land Use Impacts on Transportation). People
who work in major centers tend to commute by transit significantly more than
those who work in more dispersed locations, and they tend to drive less for
errands (
Because activities and people are
concentrated, road and parking Congestion tend to be
relatively intense in major Commercial Centers, but because people use
alternative modes and travel shorter distances, particularly for businesses
meetings, per capita traffic congestion costs tends to be lower. Commute
trips may be somewhat longer if employment is concentrated in a central
business district. For this reason, many urban planners believe that the most
efficient urban land use pattern is to have a Central Business District that
contains the highest level business activities (“main offices”), and smaller

Costs include more concentrated traffic congestion and pollution emissions, although this is usually offset by reductions in per capita vehicle use. Infill redevelopment may increase some development costs, but total development and public service costs are generally lower than dispersed, sprawl development (Litman, 2004). Other advantages and disadvantages associated with higher density development are discussed in the Land Use Evaluation chapter.

Land Use Management
Strong Commercial Centers support and are supported by Smart Growth, New Urbanism, Location Efficient Development and Transit Oriented Development land use policies. They tend to support Walking and Cycling, Public Transit, and Universal Design. They support Commute Trip Management, Parking Management, Shared Parking and Parking Pricing.
Major stakeholders include local government officials (who set land use policies), businesses (which decide where to locate and what type of building to use), residents (who may either support or oppose infill development), employers (who choose work locations and policies, such as Parking Cash Out) employees (who may support or oppose working in a Commercial Center, and customers (who decide where to shop).
Major barriers include various practical and legal constraints on clustered and infill development, and a preference among some employees and customers for more dispersed, suburban locations for commercial activities.
· Locate public facilities within Commercial Centers.
· Encourage infill development and increased density in Commercial Centers.
· Use Transit Oriented Development as a catalyst for Commercial Centers.
· Use location-based development and utility fees to encourage infill over dispersed development (Smart Growth Policy Reforms).
· Use Commute Trip Reduction programs and Parking Management to address transportation problems in Commercial Centers.
· Allow Context Sensitive Design so development can better fit into existing commercial areas.
· Discourage urban-fringe commercial development.

Concerned
about the impacts that pollution was causing on local economy, the Chattanooga
Chamber of Commerce created a Air Pollution Control Board in 1967. The board
included a diversity group of business leaders and citizens. It established a
1972 deadline for all existing major sources of pollution to be in compliance
with emission standards, which was met at a cost of $40 million. National and
international attention was focused on a city that in three years had changed
from the most polluted city in the

led to creation of the RiverCity Corporation, a private, nonprofit organization
with a mandate to implement the Riverfront Master Plan and 40 community
development goals. Among other achievements, it developed the Tennessee
Aquarium, the world’s largest freshwater aquarium, which opened in 1992. The
structure has become a trademark for the city that in 10 years transformed
itself from a dying city to one of growth and sustainable development. As a

Downtown
Revitalization (also called Main Street Programs) is intended to make
downtowns and neighborhood commercial centers more successful and attractive,
helping to create more mixed-use, infill development reflecting New Urbanist principles. Such efforts involve downtown
economic development programs, increased downtown housing, promoting community
activities (such as recreational, cultural and civic events that attract
regional residents to the downtown), Parking Management,
Traffic Calming and building rehabilitation.
Many
cities are experiencing population growth. An analysis of downtown population,
household, and income trends in 44 selected cities from 1970 to 2000 finds
that:
During the 1990s, downtown population grew by 10 percent, a
resurgence following 20 years of overall decline. Forty percent of the
sample cities began to see growth before the 1990s. While only
From 1970 to 2000, the number of downtown households increased 8 percent—13 percent in the 1990s alone—and their composition shifted. Households grew faster than population in downtowns, reflecting the proliferation of smaller households of singles, unrelated individuals living together, and childless married couples.
Downtown homeownership rates more than doubled during the
thirty-year period, reaching 22 percent by 2000. Overall the number of
homeowners grew steadily each decade. By 2000, the share of homeowners across
the sample downtowns swung from a high of 41 percent in
Downtowns are more racially and ethnically diverse than 20 years ago. From 1980 to 2000, the combined share of white and black residents living in the sample downtowns fell from 81 percent to 73 percent, while the share of Hispanic and Asian residents increased. The number of white residents living downtown rebounded in the 1990s, however, despite an overall loss of this group in cities as a whole.
In general, downtowns boast a higher percentage of both young adults and college-educated residents than the nation's cities and suburbs. In 2000, 25- to 34-year olds represented nearly a quarter of the downtown population—up from 13 percent in 1970. Forty-four percent of downtowners had a bachelors degree or higher.
Downtowns are home to some of the most and least affluent
households of their cities and regions. Twenty of the sample downtowns—such
as Midtown Manhattan, Dallas, and

this proviso, the merchants agreed to the proposal. They began to see parking
meters in a new way: as a way to fund the projects and services that directly
benefit their customers and businesses. Because parking had previously been
unpriced, the city didn’t lose anything from the general fund by dedicating the
revenue to the local area. In fact, the city gained additional revenue from
overtime fines. The city formed a PMZ advisory board consisting of business and
property owners, which recommended parking policies and set spending priorities
for the meter revenues. This approach of connecting parking revenues directly
to added public services and keeping it under local control help guarantee the
program’s success. Investments included new street furniture and trees, more
police patrols, better street lighting, more street and sidewalk cleaning,
pedestrian facility improvements and marketing (including production of area
maps showing local attractions and parking facilities. To highlight these
benefits to motorists, each parking meter has a small sticker which reads,
“Your Meter Money Will Make A Difference: Signage, Lighting, Benches, Paving”
This created a “virtuous cycle” in which parking revenue funded community improvements that attracted more visitors which increased the parking revenue, allowing further improvements. This resulted in extensive redevelopment of buildings, new businesses and residential development. Parking is no longer a problem for customers, who can almost always find a convenient space. Local sales tax revenues have increased far faster than in other shopping districts with lower parking rates, and nearby malls that offer free customer parking. This indicates that charging market rate parking (i.e., prices that result in 85-90% peak-period utilization rates) with revenues dedicated to local improvements can be an effective ways to support urban redevelopment.
Developer Christopher B. Leinberger identifies twelve specific steps for local officials, businesses and community members to create a vital, healthy and economically-successful downtown (see his report for details).
1. Capture the Vision
2. Develop a Strategic Plan
3. Forge a Healthy Private/Public Partnership
4. Make the Right Thing Easy
5. Establish Business Improvement Districts and Other Non-Profits
6. Create a Catalytic Development Company
7. Create an Urban Entertainment District
8. Develop a Rental Housing Market
9. Pioneer an Affordability Strategy
10. Focus on For-Sale Housing
11. Develop a Local-Serving Retail Strategy
12. Re-create a Strong Office Market
The
publication, Getting To Smart Growth: 100 Policies for Implementation
(SGN, 2002 and 2004) describes a variety of specific policy reforms and
administrative strategies to support more efficient development. Below are some
examples:
· Many communities offer “density bonuses” to developers who meet certain design objectives.
· The Washington State Department of Transportation has flexible design standards that allow state highway funds to be used to create wider sidewalks, curb extensions, bus stops and crosswalk improvements on urban arterials.
· The San Francisco Bay Area Metropolitan Transportation Commission provides special funding for transit-oriented development improvements such as pedestrian and cycling facilities, streetscape improvements and transit village development for areas within one-third mile walk of a transit station. Funding increased with development densities: $1,000 per bedroom in projects containing 25 units per acre, and up to $2,000 per bedroom for developments with 60+ units per acre.
·
The city of
· The Maryland DOT’s neighborhood conservation program provides funding for transportation improvements on roadways and other transportation facilities located in state designated neighborhoods (often referred to as neighborhood revitalization areas), where the improvements will provide economic revitalization and improved livability to older, run-down neighborhoods. Eligible projects include roadway repaving or reconstruction, roadway signing, lighting and traffic controls, walking improvements, bus shelters and transit station access improvements, streetscaping, etc.
