ABSTRACT
In 2011, Maryland adopted a different approach to evaluating sustainability, because the usual indicators of progress, such as gross domestic product, address only economic transactions, ignoring the environmental and social costs of material production and consumption. Maryland's Genuine Progress Indicator includes measures of social and environmental health to help residents and policy makers better understand the true costs and benefits of resource utilization decisions. Concerning best practices for a given land- use pattern, some observers, including Feiden, say that any land-use pattern requiring cars and having a density too low to support high- quality transit is inherently unsustainable. A refreshing approach to sustainability that is much less list-laden and more visionary and inspiring is the one advocated by Heyman Judy and Michael Corbett in designing sustainable communities. In 2011, the American planning association published yet another list detailing eight new principles of planning for sustainable places.
