It shall be unlawful to extract groundwater underlying County, directly or indirectly, for use of that groundwater so extracted, outside County boundaries, without first obtaining a Permit as provided in this Chapter. The extraction of groundwater to replace a surface water supply to be transferred for use outside County boundaries shall be considered an indirect extraction of groundwater for purposes of this section, which shall require a Permit. This Chapter shall not apply for the extraction of groundwater (1) to prevent the flood of lands or (2) to prevent the saturation of the root zone of farmland, or (3) for use within the District boundaries of a District which is in part located within County and in part in another County(s) where such extraction quantities and use are consistent with historical practices of the District, or (4) for extractions to boost heads for portions of District facilities, consistent with historical practices of the District, or (5) for use on lands outside the County which are contiguous and in the same ownership to lands within the County from which the groundwater is extracted, where such extraction quantities and the use are consistent with historical practices of the landowners. The applicant shall have the burden of supporting an assertion of an historical practice with competent evidence. (§ 1, Ord. 1195, eff. December 26, 1996, as amended by § 1, Ord. 1210, eff. October 23, 1997)
