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 Retail Location and Transit: An Econometric Examination of Retail Location in Prince George’s and Montgomery County, Maryland(2014) Knaap, Elijah; Knaap, Gerrit; Ma, TingTransit oriented development (TOD) is a widely accepted policy objective of many jurisdictions in the United States. There is both anecdotal and empirical evidence to suggest that the vitality of TODs and the transit boardings from any TOD depends significantly on the extent of retail development in the transit station area. We focus in this paper, on the determinants of retail location in two counties, Montgomery County and Prince George’s County, Maryland, with a particular focus on the influence of proximity to rail transit stations. We used data from two counties in the Washington DC suburbs to construct measures of transit and retail accessibility and constructed an econometric model to estimate the relationship between urban contextual factors and retail firm locations. The results from our analysis provide empirical support for the notion that retail firms are attracted to locations with high levels of transit accessibility. By extension, these findings suggest that investments in transit—particularly fixed rail transit—may be an effective method for stimulating retail development in metropolitan areas.Item Exploring Alternative Futures Using a Spatially Explicit Econometric Model(2008) Kaza, Nikhil; Knaap, Gerrit; Meade, DouglasThis paper illustrates the application of various forecasting methodologies in constructing multiple scenarios for the state of Maryland using Long term Inter Industry Forecasting Tool that tracks inter-industry outputs at a macro scale, and State Employment Model that disaggregates these outputs to the states. We then use accessibility, land availability and observed relationships of employment categories to distribute employment at a county level. In this paper, we identify the possible advantages and pitfalls of using large scale economic models to drive employment forecasts at the county level. This framework allows for simulating the implications of macroeconomic scenarios such as changes in exchange rates and unemployment levels, as well as local land use and transportation policies on local employment and demographics. In particular, we focus on two scenarios as test cases both of which involve very different ideas about how future might unfold and their effects on land use and transportation policy prescriptions. One of the scenarios involves, among others, rises in health care spending over the next few years and the other involves increases in energy prices. As will be shown, they have different spatial effects and suggest different policy actions on the part of various governments.Item Economic Scenarios and Development Patterns in the Baltimore‐Washington Region(2009) Clifton, Kelly; Kaza, Nikhil; Knaap, GerritThis paper illustrates the use of scenarios in land use, environmental and transportation planning in and around the State of Maryland. Different assumptions about futures result in different patterns of growth with differential impacts on particular sectors of the economy. Such different patterns require formulation of contingent plans as well as robust plans. In this paper, we illustrate the quantitative modelling methodology of loosely linked economic demographic, transportation and other impact assessment models in constructing two scenarios; one of which represented the best possible guess about the continuation of the future and other involving rapid changes to energy prices and Federal spending. We illustrate the spatial development outcomes and the transportation and environmental plans that are necessary to deal with these different outcomes. Further, we illustrate that different planned actions have different efficacies in different futures and thus multiple futures should be carefully considered. Finally, we illustrate the notions of contingent plans and robust plans.Item Does Job Creation Tax Credit Program in Maryland Induce Spatial Employment Growth or Redistribution?(2002) Knaap, Gerrit; Sohn, JungyulThe Job Creation Tax Credit (JCTC) program is one of the five major Smart Growth Programs initiated by the State of Maryland in 1996 and amended in 1997. Like other tax credit programs it is intended to create jobs, but it is also a place-based policy in the sense that eligibility is limited to jobs created in Priority Funding Areas (PFAs). This paper examines whether the JCTC program has furthered the goals of smart growth by concentrating job growth within well defined regions of the state. Towards this end, both the number and the relative share of employment inside and outside of the PFAs are compared using three econometric models. The empirical analysis examines employment in five economic sectors ((1) primary, (2) manufacturing, (3) transportation, communication and utilities (T.C.U.), (4) finance, insurance and real estate (F.I.R.E.) and (5) services) over the years (1994 to 1998) using ZIP Code data. The result shows that jobs in the T.C.U. and services industries have responded to the state incentive program while three other sectors have not; the distribution of jobs in the primary sector have grown counter to the state incentive policy and jobs in manufacturing and F.I.R.E. have been unaffected by the program.Item Mapping Opportunity: A Critical Assessment(2014) Knaap, Elijah; Knaap, Gerrit; Liu, ChaoA renewed interest has emerged on spatial opportunity structures and their role in shaping housing policy, community development, and equity planning. To this end, many have tried to quantify the geography of opportunity and quite literally plot it in a map. In this paper we explore the conceptual foundations and analytical methods that underlie the current practice of opportunity mapping. We find that opportunity maps can inform housing policy and metropolitan planning but that greater consideration should be given to the variables included, the methods in which variables are geographically articulated and combined, and the extent to which the public is engaged in opportunity mapping exercises.Item Talking Smart in the United States(2002) Knaap, GerritAs in many countries around the world, concerns about contemporary urban development patterns and their effects on the natural and social environment are high and rising in the United States. Though these concerns are not new, the recent period of sustained economic growth has led to both rapid urban expansion and falling relative concerns about other problems like crime, unemployment, and government deficits. Urban sprawl is now a major public policy issue (U.S. Office of Technology Assessment 1995, U.S. General Accounting Office (GAO) 1999, GAO 2000). How to address -- even define -- the problem, however, remains unresolved and contentious. Some view urban sprawl as a major threat to environmental quality, fiscal stability, and human health. Those with this point of view support policy reforms sometimes called smart growth, new urbanism, and sustainable development (Ewing 1997, Smart Growth Network 2002). To others, sprawl is simply the result of increases in population, rising real incomes, and the expression of consumer demands (Brueckner 1999). To those with this point of view, there is little evidence that urban sprawl has adverse social or environmental consequences or warrants a policy response (Gordon and Richardson 1997, Urban Futures 2002). In a nation rich in land resources and steeped in traditions of private property rights, this view is not easily dismissed.
