This study compares net impacts of developmental potentials, externalities, and uncertainties associated with the urban growth boundary (UGB) with those of certainty and tax savings in the exclusive farm use (EFU) districts on land values in Portland, OR, using a hedonic Thünian econometric model. Using a geographic information systems-based data set of Christmas tree and horticultural farms, value effects of the urban growth boundary were found to vary by farm size, land use, and proximity to urban activities. The results suggested that proximity to negative externalities associated with urban activities had strong impacts on farming within the UGB. These impacts overweighed advantages associated with tax savings and increasing certainty within EFU districts. © 2007 Sage Publications.
