Urban Growth and Decline: The Role of Population Density at the City Core
December 21, 2011|Economic Commentary, Federal Reserve Bank of Cleveland

In recent decades, some cities have seen their urban centers lose population density, as residents spread farther out to suburbs and exurbs. Others have kept populous downtowns even as their environs have grown. Population density in general has economic advantages, so one might wonder whether a loss of density, which may be a symptom of negative economic shocks, could amplify those shocks. This paper looks at four decades of census data and show that growing cities have maintained dense urban centers, while shrinking cities have not. There are reasons to think that loss of population density at the core of the city could be particularly damaging to productivity. If this is the case, there could be productivity gains from policies aimed at reversing that trend.
10 Strategies For Attracting Investment Near Transit

Background
Over the next 25 years, the San Francisco Bay Area is projected to grow by an estimated 22 percent—adding around 1.6 million new residents. Land use and development professionals are engaged in a dialogue around how the region can accommodate this growth in a way that maintains the extraordinary quality-of-life that attracts people to live and work in the region. With an eye toward demographic shifts like an aging population and an increasing number of smaller and non-family households, planners and developers recognize the growing demand for homes and jobs in walkable, urban environments.
High land and housing costs in the core areas of the region, however, create continued development pressure in the outskirts of the region, leading to commute-times and household transportation costs that are among the highest in the nation. The high cost of housing and transportation is particularly felt by the region’s moderate- and lower-income families, who in some cities spend as…
Model Design Manual for Living Streets

Context
A growing number of communities are discovering the value of their streets as important public spaces for many aspects of daily life. People want streets that are safe to cross or walk along, offer places to meet people, link healthy neighborhoods, and have a vibrant mix of retail. More people are enjoying the value of farmers’ markets, street festivals, and gathering places. And more people want to be able to walk and ride bicycles in their neighborhoods.
People from a wide variety of backgrounds are forming partnerships with schools, health agencies, neighborhood associations, environmental organizations, and other groups in asking their city councils to create streets and neighborhoods that fit this vision.
As a result, an increasing number of cities are looking to modify the way they design their streets. They are often stifled by standards and guidelines that prevent them from making the changes they seek. Some want to modify their standards and manuals, but don’t…
Walking to the station: The effects of street connectivity on walkability and access to transit

Summary
This thesis analyzes an on-board transit survey conducted by the Atlanta Regional Commission in order to determine how far urban density, mixed land-uses, and street network connectivity are related to different walking behaviors, namely transit walk-mode shares and walking distances to/from stations. The data are drawn from all the stations of Atlanta’s rapid transit network (MARTA).
Allowing for quite a bit of noise in the data, some of the findings confirm for the case of Atlanta what a review of existing literature would lead one to expect: mixed land-use and denser street networks are associated with higher proportion of riders traveling to/from the station “walking” (noise in the data does not allow to fully distinguish with certainty walking as the sole mode of access to/from the station from walking combined with the use of bus services).
The thesis also explores questions that have not been previously covered systematically in the literature. First, does urban…
Overlooked Density: Rethinking Transportation Options in Suburbia

Executive Summary
Suburban multifamily housing is an often overlooked housing typology that is the fastest growing housing market in the country and holds strong potential for achieving smart growth goals in suburbia. This housing type is ubiquitous throughout all regions in the nation, is a widespread example of density in suburbia, and is typically located next to commercial uses. The proximity between suburban multifamily housing and commercial uses creates the potential for nodes of concentrated activity, mixed use, and the possibility of substantial non-auto transport in suburbia. While this potential exists, the design of this housing type often follows an enclaved pattern of development, negating any synergy, minimizing the possibility of non-auto transport, and denying any potential for sustainable development.
Through case studies of suburban multifamily development in Oregon, Arizona, Florida, and Massachusetts, this report looks at the specific ways in which regulation,…

This report has been developed in response to widespread interest for improving both mobility choices and community character through a commitment to creating and enhancing walkable communities. Many agencies will work toward these goals using the concepts and principles in this report to ensure the users, community and other key factors are considered in the planning and design processes used to develop walkable urban thoroughfares.

Bringing work back to the city
Since 1990, Bay Area residents have been driving nearly 50 million more miles each day. Regionally, transit ridership to work fell from a high of 11.4 percent in 1980 to around 9.4 percent in 2000. Although it has increased slightly since 2000 (to 9.8 percent), Bay Area transit ridership remains less than 10 percent of all commute trips. Meanwhile, our heavy reliance on automobile commutes is one the Bay Area’s chief contributions to climate change. This pattern of driving to work and other destinations — and its resulting environmental impact — stems from the sprawling geography of homes and jobs, and an infrastructure system that builds ever outward.
The smart growth movement has long called attention to the problems with sprawl, but has often been focused on residential sprawl. Yet the dispersion of jobs into suburban and exurban office parks that can never be served by transit is just as much of a threat to the environment as residential…
