PRGWB Area of Severe Decline

If your property uses water from within the area of severe decline, then your property is not eligible for the 5 AFY exemption for new irrigated crop production for properties without existing irrigated crop production. ​

The County Land Use Ordinance originally defined the area of severe decline within the PRGWB as the area where groundwater elevation levels dropped 50 feet or more from Spring 1997 to Spring 2013, based on groundwater level contours generated using a computer-based contouring program, which are based on groundwater elevations measured at monitoring well locations. Click here for a technical memo explaining the mapping methodology.
