Urbanization is the key driver of land use change across the globe and in the United States. When examining urban growth in many natural amenity-rich regions, such as northern Idaho, the tension between urban and population growth and land developability or conservation has been of greater importance. In this study, we conducted an analysis of the urban growth pattern and underlying drivers through a case of Coeur d’Alene in Northern Idaho. Results derived from spatial-temporal dynamics analysis suggest that both macro-level economic development contexts (e.g., the economic recession in the 2000s) and local level zoning regulation play a key role in shaping the spatial patterns of new urban areas in the greater Coeur d’Alene region. Furthermore, by using logistic regression analysis, we found that there has been a very high preference to develop land near to existing city boundaries and in close proximity to water and in areas with a high percentage of Bachelor degrees. The application of geographically weighted logistic regression not only improved model prediction accuracy and goodness of fit, but also allowed us to examine the local variations and influences of each of the independent variables.
