The Memorandum of Understanding with the State of California
Regional Water Quality Control Board allows for wet weather
percolation and groundwater testing between January
1 and March 1,
and after having received 50% of the average rainfall.
Depth to groundwater determinations can be conducted within ten (10)
calendar days following a rainfall of 0.8 inches in a 48 hour period.
Sonoma County is divided into 7 geographic areas for this purpose.
The amount of rainfall will be posted for each area.
