This paper reviews different approaches to using transferable development rights (TDRs) as a way to preserve rural lands in the face of development pressure. One TDR program is examined in detail, that of Calvert County, Maryland, which has had an active TDR market since the mid-1980s. This...

Urban density is a key feature of urban structure, and there is continuing interest in what determines density and how it might be influenced over time. Residential lot sizes are the underlying determinant of urban density, and lot sizes are determined by complex interactions of supply and...

The paper explores a number of issues related to lot size and urban density. First, trends in single-family residential lot size over the past 35 years are examined in eight counties in the state of Maryland.
