Hydrogeologic Studies

Hydrogeologic Study Reports

Hydrogeologic study reports are submitted to the county in support of land development proposals involving relatively large withdrawals of groundwater or, more commonly, for planned subdivisions of 10 or more lots that will be supplied by groundwater.

The reports include geologic and groundwater data collected by hydrogeologic and engineering consulting firms from drilling and testing wells on the property. This information is evaluated to determine if the quantity and quality of groundwater can support the proposed use and are sustainable.

Information collected for these studies provides scientists with information to help improve the overall understanding of the complex hydrogeologic conditions in the county for resource development and management purposes. Since the early 1980s, over 165 hydrogeologic studies have been conducted and the reports submitted to the county. View a map where hydrogeological studies have been conducted (PDF).
