Cal. Water Code § 37942

The groundwater management plan may include a policy for the issuance of new well permits that takes into consideration the location of proposed wells and area of use, projected extractions from the wells, and the effect of the extractions on existing users and on storage. In developing the management plan, the district may consider a ban on new irrigated acreage or new municipal water system wells. The district may include a contingency plan to deal with seawater intrusion, basin contamination, or other risks that could impair the ability to rely on the basin for groundwater.
