    Comparing objective measures of environmental supports for pedestrian travel in adults
    (Springer Nature, 2009-11-19) Shay, Elizabeth; Rodriguez, Daniel A; Cho, Gihyoug; Clifton, Kelly J; Evenson, Kelly R
    Evidence is growing that the built environment has the potential to influence walking--both positively and negatively. However, uncertainty remains on the best approaches to representing the pedestrian environment in order to discern associations between walking and the environment. Research into the relationship between environment and walking is complex; challenges include choice of measures (objective and subjective), quality and availability of data, and methods for managing quantitative data through aggregation and weighting. In particular, little research has examined how to aggregate built environment data to best represent the neighborhood environments expected to influence residents' behavior. This study examined associations between walking and local pedestrian supports (as measured with an environmental audit), comparing the results of models using three different methods to aggregate and weight pedestrian features. Using data collected in 2005-2006 for a sample of 251 adult residents of Montgomery County, MD, we examined associations between pedestrian facilities and walking behaviors (pedestrian trips and average daily steps). Adjusted negative binomial and ordinary least-squares regression models were used to compare three different data aggregation techniques (raw averages, length weighting, distance weighting) for measures of pedestrian facilities that included presence, condition, width and connectivity of sidewalks, and presence of crossing aids and crosswalks. Participants averaged 8.9 walk trips during the week; daily step counts averaged 7042. The three aggregation techniques revealed different associations between walk trips and the various pedestrian facilities. Crossing aids and good sidewalk conditions were associated with walk trips more than were other pedestrian facilities, while sidewalk facilities and features showed associations with steps not observed for crossing aids and crosswalks. Among three methods of aggregation examined, the method that accounted for distance from participant's home to the pedestrian facility (distance weighting) is promising; at the same time, it requires the most time and effort to calculate. This finding is consistent with the behavioral assumption that travelers may respond to environmental features closer to their residence more strongly than to more distant environmental qualities.

    Smart Growth in Maryland: Looking Forward and Looking Back
    (2007) Frece, John; Knaap, Gerrit
    Spring of 2007 will mark the 10th anniversary of the passage of Maryland’s Smart Growth and Neighborhood Conservation Initiative; an effort designed to discourage sprawl development, foster more compact communities, protect the best remaining farms and open space in the state, and save taxpayers from the growing cost of providing services and infrastructure to serve far-flung development. Almost before its various provisions took effect in 1997 and 1998, the Maryland initiative generated interest and acclaim across the country. It received numerous awards and became the principal legacy of the program’s primary architect, former Governor Parris N. Glen- dening. Governors in other states, such as New Jersey, Colorado and Massachusetts, instituted their own “smart growth” proposals, often modeled after portions of the Maryland program. Even the popularity and wide usage of the now omnipresent phrase “smart growth” can be attributed in large part to the Maryland program. But, what has been the effect of Maryland’s Smart Growth pro- gram? Looking at it some ten years later, has it worked? Did it accomplish what it was designed to do? What have been the strengths and weaknesses of the Maryland approach, and how can lessons from the Maryland experience be used to offer a new set of policymakers in Maryland, as well as elsewhere in the nation, practical suggestions on how to make smart growth smarter?

    The Puzzle of Local Double Taxation: Why Do Private Community Associations Exist?
    (The Independent Review, 2009) Nelson, Robert
    Private community associations have spread quickly in many parts of the United States, even though their members must pay both association dues and local taxes for similar services. Not only do private community associations offer several advantages over traditional governance structures, but local governments often encourage developers to establish them.

    The Rise of Private Neighborhood Associations: A Constitutional Revolution in Local Government
    (Edward Elgar Publishing, 2002) Nelson, Robert H.
    A revival of the neighborhood is seen by many commentators as a key element in a wider effort to reenergize the intermediate institutions of American society. The weakening of these institutions is blamed for a decline in trust, public spirit, and generally an erosion of civic values in the United States in recent decades. The rise of the private neighborhood follows in the wake of the rise of the corporate form of business ownership of property in the late nineteenth century, both representing fundamental turns away from individual ownership of private property and towards new collective forms of private ownership. Indeed, the rise of private neighborhood associations represents the most important property right development in the United States since the rise of the modern business corporation.

    Assessing the impact of urban form measures in nonwork trip mode choice after controlling for demographic and level-of-service effects
    (2003) Rajamani, Jayanthi; Bhat, Chandra R.; Handy, Susan; Knaap, Gerritt; Song, Yan
    The relationship between travel behavior and the local built environment continues to be a contentious issue, despite several research efforts in the area. The current paper investigates the significance and explanatory power of a variety of urban form measures on nonwork activity travel mode choice. The travel data used for analysis is the 1995 Portland Metropolitan Activity Survey conducted by Portland Metro. The database on the local built environment was developed by Song (2002) and includes a more extensive set of variables than previous studies that have examined the relationship between travel behavior and the local built environment using the Portland data. A multinomial logit mode choice model results indicate that higher residential densities and mixed-uses promote walking behavior for nonwork activities.

    Internally Connected, No Commercial, With a Touch of Open Space: The Neighborhoods of New Homes in the Portland Metropolitan Area
    (2004) Song, Yan; Knaap, Gerrit
    For many years, neighborhoods have been classified as either “suburban” or “traditional.” But new homes today are built in many different types of neighborhoods with many different design features. In this paper, we develop a quantitative method for classifying the neighborhoods of new homes in the Portland metropolitan area. We proceed in three steps. First we measure urban form attributes of neighborhoods around newly developed homes. We then use factor analysis to identify a small set of factors that capture essential differences in urban form. Finally we use cluster analysis on these factor scores to identify distinctly different neighborhood types. Applying these methods to neighborhoods around new single family homes in the metropolitan Portland, Oregon, we are able to identify eight factors of urban form and six neighborhood types. We then show that most new single family homes in metropolitan Portland are built in new suburban neighborhoods but a substantial portion is occurring in traditional urban neighborhoods.

    Economies of Scale in Wastewater Treatment and Planning for Urban Growth
    (2003) Hopkins, Lewis; Knaap, Gerrit; Xiaohuan, Xu
    Can urban growth patterns take advantage of economies of scale in infrastructure by relying on fewer and larger treatment plants? Estimates of potential cost savings from alternative wastewater treatment consolidation strategies for the metropolitan Chicago region suggest that the timing of consolidation is important. Carefully timed consolidation, even consolidation that occurs after development has occurred, might yield present value savings on the order of $170 million in capital costs. These potential savings are large enough that such strategies should be considered when planning for metropolitan growth.

    Information Technology in the 1990s: More Footloose or More Location-bound?
    (2002) Sohn, Jungyul
    This paper examines if information technology has worked towards dispersion or concentration of economic activities in two steps of analysis. The first analysis using locational Gini coefficient and Moran’s I focuses on distribution of the urban area as a whole and finds that dispersion was prominent over the years. The second analysis using Gi* statistic as the dependent variable in the regression model, however, shows that the technology has induced more concentration rather than dispersion at an intrametropolitan scale, reflecting that there is a discrepancy in the results of the two analyses depending on the spatial scale of the analysis.

    Determinants and Effects on Property Values of Participation in Voluntary Cleanup Programs: The Case of Colorado
    (2005) Alberini, Anna
    State 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.

    What Are the Effects of Contamination Risks on Commercial and Industrial Properties? Evidence from Baltimore, Maryland
    (2005) Alberini, Anna; Longo, Alberto
    Using the hedonic pricing approach, we investigate how the information released on public registries of contaminated and potentially contaminated sites affects nearby commercial and industrial properties in Baltimore, Maryland. We find that commercial and industrial properties are virtually unaffected by proximity to a site with a history of contamination. Knowing that the site is no longer considered contaminated does not have a rebound effect on property prices either. We also find that urban economic development policies, such as Empowerment Zones and Enterprise Zones, have little effect on property values. In sum, brownfield properties in Baltimore are not particularly attractive investments for developers, and there is little potential for self-sustaining cleanup based on appropriate fiscal incentives, such as Tax Increment Financing. It is doubtful that “one size fits all” measures to encourage the cleanup of contaminated sites can be successful in this context.
