Designing Urban Corridors

Some communities have begun to demand more attractive and functional roadside development. This report shows how to use corridor-specific plans to create a sense of order and place in an increasingly cluttered landscape. These plans integrate well-known regulatory techniques to improve the function, safety, and appearance of corridors. The report includes strategies to improve unsightly and unsafe commercial roadway corridors and techniques to identify and protect scenic corridors. Includes sample corridor development standards from three communities.

Corridor redevelopment is not a new topic. Various planning and design approaches--such as complete streets, living streets, and livable streets--aim to redevelop commercial corridors to meet more of their users' needs, including their need for walking and biking rather than just traveling by car. A marked difference between a healthy corridors approach and other approaches is that the former looks beyond just the street and considers how the street supports the daily needs of all who live, work, and travel along it. Building Healthy Corridors: Transforming Urban and Suburban Arterials into Thriving Places takes a comprehensive view and considers how the corridor contributes to the overall health of the surrounding community, including community members' opportunities to be physically active. It also considers safety, housing affordability, transportation options, environmental sustainability, and social cohesion as well as modifications that would link residents to the corridor and improve connections to jobs and adjacent parts of the community.

As the US population grows—potentially adding more than 110 million people by 2050—cities and their suburbs will continue expanding, eventually meeting the suburbs of neighboring cities and forming continuous urban megaregions. There are now at least a dozen megaregions in the US, such as the one extending from Richmond, Virginia, to Portland, Maine, and the megaregion that runs from Santa Barbara through Los Angeles and San Diego, down to the Mexican border. In Designing the Megaregion, planning and urban design expert Jonathan Barnett takes a fresh look at designing megaregions. Barnett argues that planning megaregions requires ecological literacy and a renewed commitment to social equity in order to address the increasing pressure this growth puts on natural, built, and human resources. If current trends continue, new construction in megaregions will put additional stress on natural resources, make highway gridlock and airline delays much worse, and cause each region to become more separate and unequal. Barnett offers an incremental approach to designing at the megaregional scale that will help prepare for future economic and population growth. Designing the Megaregion explains how we can, and should, redesign megaregional growth using mostly private investment, without having to wait for large-scale, government initiatives and trying to create whole new governmental structures. Barnett explains practical initiatives for adapting development in response to a changing climate, improving transportation systems, and redirecting the forces that make megaregions very unequal places. There is an urgent need to begin designing megaregions, and Barnett offers a hopeful way forward using systems that are already in place.

The NACTO Urban Street Design Guide shows how streets of every size can be reimagined and reoriented to prioritize safe driving and transit, biking, walking, and public activity. Unlike older, more conservative engineering manuals, this design guide emphasizes the core principle that urban streets are public places and have a larger role to play in communities than solely being conduits for traffic. The well-illustrated guide offers blueprints of street design from multiple perspectives, from the bird’s eye view to granular details. Case studies from around the country clearly show how to implement best practices, as well as provide guidance for customizing design applications to a city’s unique needs. Urban Street Design Guide outlines five goals and tenets of world-class street design: • Streets are public spaces. Streets play a much larger role in the public life of cities and communities than just thoroughfares for traffic. • Great streets are great for business. Well-designed streets generate higher revenues for businesses and higher values for homeowners. • Design for safety. Traffic engineers can and should design streets where people walking, parking, shopping, bicycling, working, and driving can cross paths safely. • Streets can be changed. Transportation engineers can work flexibly within the building envelope of a street. Many city streets were created in a different era and need to be reconfigured to meet new needs. • Act now! Implement projects quickly using temporary materials to help inform public decision making. Elaborating on these fundamental principles, the guide offers substantive direction for cities seeking to improve street design to create more inclusive, multi-modal urban environments. It is an exceptional resource for redesigning streets to serve the needs of 21st century cities, whose residents and visitors demand a variety of transportation options, safer streets, and vibrant community life.

The loss and fragmentation of natural habitats is one of the major issues in wildlife management and conservation. Habitat "corridors" are sometimes proposed as an important element within a conservation strategy. Examples are given of corridors both as pathways and as habitats in their own right. Includes detailed reviews of principles relevant to the design and management of corridors, their place in regional approaches to conservation planning, and recommendations for research and management.

Economic corridors—ambitious infrastructural development projects that newly liberalizing countries in Asia and Africa are undertaking—are dramatically redefining the shape of urbanization. Spanning multiple cities and croplands, these corridors connect metropolises via high-speed superhighways in an effort to make certain strategic regions attractive destinations for private investment. As policy makers search for decentralized and market-oriented means for the transfer of land from agrarian constituencies to infrastructural promoters and urban developers, the reallocation of property control is erupting into volatile land-based social conflicts. In Shareholder Cities, Sai Balakrishnan argues that some of India's most decisive conflicts over its urban future will unfold in the regions along the new economic corridors where electorally strong agrarian propertied classes directly encounter financially powerful incoming urban firms. Balakrishnan focuses on the first economic corridor, the Mumbai-Pune Expressway, and the construction of three new cities along it. The book derives its title from a current mode of resolving agrarian-urban conflicts in which agrarian landowners are being transformed into shareholders in the corridor cities, and the distributional implications of these new land transformations. Shifting the focus of the study of India's contemporary urbanization away from megacities to these in-between corridor regions, Balakrishnan explores the production of uneven urban development that unsettles older histories of agrarian capitalism and the emergence of agrarian propertied classes as protagonists in the making of urban real estate markets. Shareholder Cities highlights the possibilities for a democratic politics of inclusion in which agrarian-urban encounters can create opportunities for previously excluded groups to stake new claims for themselves in the corridor regions.
