The National Center for Smart Growth (NCSG) works to advance the notion that research, collaboration, engagement and thoughtful policy development hold the key to a smarter and more sustainable approach to urban and regional development. NCSG is based at the University of Maryland, College Park, housed under the School of Architecture, Planning, and Preservation, with support from the College of Agriculture & Natural Resources, the A. James Clark School of Engineering, the School of Public Policy, and the Office of the Provost.

Item Determinants and Effects on Property Values of Participation in Voluntary Cleanup Programs: The Case of Colorado(2005) Alberini, AnnaState Voluntary Cleanup Programs (VCPs) were established starting in the 1990s to encourage the environmental remediation and redevelopment of contaminated properties. These programs typically offer liability relief, subsidies and other regulatory incentives in exchange for site cleanup. This paper asks three questions: First, what type of properties are attracted to voluntary cleanup programs? Second, what is the interaction between these state programs and other incentives for remediation and economic development, such as Enterprise Zone and Brownfield Zone designations? Third, what is the effect of participation in the VCP on property values? We use data from Colorado’s VCP to answer these questions. We find that most of the properties enrolled in this program were not previously listed on EPA’s contaminated site registries, and that most applicants seek to obtain directly a “no further action” determination without undergoing remediation. The main determinants of participation are the size of the parcel and whether the surrounding land use is primarily residential, while other incentives have little effect. Properties with confirmed contamination sell at a 47% discount relative to comparable uncontaminated parcels, and participation tends to raise the property price, but this latter effect is not statistically significant. Taken together, these findings suggest that the participating properties are those with high development potential, and hint at the possibility that owners or developers may be seeking to obtain a clean bill of health from the State with only minimal or no cleanup efforts. Were these findings confirmed with data from other states, they would raise doubts about the effectiveness of voluntary programs in encouraging remediation and their usefulness in reversing some of the undesired effects of the Superfund legislation.Item Travel and Environmental Implications of School Siting(2003) Ewing, ReidTravel and Environmental Implications of School Siting, released by the EPA on October 8, 2003, is the first study to empirically examine the relationship between school locations, the built environment around schools, how kids get to school, and the impact on air emissions of those travel choices. Over the next few decades, communities making decisions about the construction and renovation of thousands of schools will be challenged to meet multiple goals -- educational, fiscal, and environmental. The study finds that: School proximity to students matters. Students with shorter walk and bike times to school are more likely to walk or bike. The built environment influences travel choices. Students traveling through pedestrian-friendly environments are more likely to walk or bike. Because of travel behavior differences, school location has an impact on air emissions. Centrally located schools that can be reached by walking and bicycling result in reduced air emissions from driving. More data collection and research are needed to add further to the understanding of these effects. Specifically, improved data about both school travel and the built environment as well as new modeling techniques can build on these results. For some time, there has been a trend toward construction of big schools and requirements for large sites. Guidelines, recommendations, and standards that encourage or require building large schools on new campuses or discourage renovation are embedded in a variety of state and local regulations, laws and funding formulas. This study provides important information about the effect of school location on how children get to school. It shows that school siting and design can affect choices of walking, biking, or driving. In turn, these changes in travel choices could affect traffic congestion, air pollution, and school transportation budgets.Item Measuring the Health Effects of Sprawl: A National Analysis of Physical Activity, Obesity and Chronic Disease(2003) Ewing, Reid; McCann, BarbaraThe findings presented here are from the article, Relationship Between Urban Sprawl and Physical Activity, Obesity and Morbidity, by Reid Ewing, Tom Schmid, Richard Killingsworth, Amy Zlot, and Stephen Raudenbush, published in the September 2003 issue of the American Journal of Health Promotion. This report is intended to make this important piece of research more accessible to the general public. In addition to presenting research findings, this report summarizes recent research done by others on the links between the way we’ve built our communities, physical activity, and health. It also includes recommendations for change and resources for those interested in further exploration of this topic.Item Identifying and Measuring Urban Design Qualities Related to Walkability(2005) Clemente, Otto; Ewing, ReidIn active living research, measures used to characterize the built environment have been mostly gross qualities such as neighborhood density and park access. This project has developed operational definitions and measurement protocols for subtler urban design qualities believed to be related to walkability. METHODS: Methods included: 1) recruiting an expert panel; 2) shooting video clips of streetscapes; 3) rating urban design qualities of streetscapes by the expert panel; 4) measuring physical features of streetscapes from the video clips; 5) testing inter-rater reliability of physical measurements and urban design quality ratings; 6) statistically analyzing relationships between physical features and urban design quality ratings, 7) selecting of qualities for operationalization, and 8) developing of operational definitions and measurement protocols for urban design qualities based on statistical relationships. RESULTS: Operational definitions and measurement protocols were developed for five of nine urban design qualities: imageability, visual enclosure, human scale, transparency, and complexity. CONCLUSIONS: A field survey instrument has been developed, tested in the field, and further refined for use in active living research.Item Getting Cars Off the Road: The Cost-Effectiveness of an Episodic Pollution Control Program(2010) Alberini, Anna; Baur, Patrick; Cropper, Maureen; Jiang, YiGround level ozone remains a serious problem in the United States. Because ozone non-attainment is a summer problem, episodic rather than continuous controls of ozone precursors are possible. We evaluate the costs and effectiveness of an episodic scheme that requires people to buy permits in order to drive on high ozone days. We estimate the demand function for permits based on a survey of 1,300 households in the Washington, DC metropolitan area. Assuming that all vehicle owners comply with the scheme, the permit program would reduce VOCs by 50 tons and NOx by 42 tons per Code Red day at a permit price of $75. Allowing for non-compliance by 15% of respondents reduces the effectiveness of the scheme to 39 tons of VOCs and 33 tons of NOx per day. The cost per ozone season of achieving these reductions is approximately $9 million (2008 USD). This compares favorably with permanent methods of reducing VOCs that cost $645 per ton per year.
