California Code, Public Resources Code - PRC § 3602

Where a parcel of land contains one acre or more, but is less than 250 feet in width, there may be drilled on the parcel of land not more than one well to each acre of the area if the surface location of any well or wells is so placed as to be as far from the lateral boundary lines of the parcel of land as the configuration of the surface and the existing improvements thereon will permit.
