Lot Size Regulations and Water Quality Protection: The Case for Large Lots in Rural Areas

Reference Type
Conference Proceedings (Chapter)

"Development at the rural - urban interface has many consequences for the natural environment. In areas rich with surface water resources such as lakes and streams, the urbanization of the landscape can dramatically transform the natural hydrology and threaten high quality water resources. This paper examines the relationships between parcelization, development, impervious surfaces, stormwater runoff and surface water quality in the urban - rural interface. We focus on the impact s of impervious surfaces and developed pervious surfaces (lawns) on stormwater infiltration. Drawing on existing research, we develop a new model to quantify the nutrient loading that is associated with various lot sizes. We then apply this model to a rural watershed experiencing exurban development pressure. The model indicates that without requiring landowners to implement stormwater management best management practices, the continuing division of land into smaller parcels and subsequent development will most likely result in water quality degradation. These results have significant implications for local, state, and national policy makers seeking to manage development in ways that ensures the long-term sustainability of critical freshwater resources. They suggest that large lot requirements may be necessary in the short term in order to manage the increase in impervious surfaces. These results potentially contradict development and stormwater policy recommendations derived from more urban contexts." [Abstract from Conference Program and Book of Abstracts]
