Note: Editor's Note: Following the approval of Inyo County Ordinance No. 394, in 1980, now set forth as Chapter 7.01 of the Inyo County Code, the City of Los Angeles challenged the ordinance in Inyo County Superior Court Case No. 12908. The Superior Court tentatively ruled that the ordinance was unconstitutional and preempted by state law. The current status of 7.01 is set forth in Section XXVIII of the Inyo County/Los Angeles Long Term Water Agreement entered as an order of the court in Inyo County Superior Court (Case No. 12908) which provides as follows:

A final order in Inyo County Superior Court Case No. 12908 on this Court's ruling on Inyo County's Groundwater Ordinance shall not be entered or filed. 110 Additionally, during the term of this Stipulation and Order, the County its agents, servants, officers, and employees, and all other persons acting in concert with the County, are enjoined from applying, implementing or enforcing in any manner whatsoever, the Inyo County Owens Valley Groundwater Management Ordinance enrolled as Chapter 7.01 of the Inyo County Code, and Inyo County Ordinance Number 395; provided however, that the Inyo County Water Commission, may remain in existence to carry out the provisions of this Stipulation and Order. Further, during the term of this Stipulation and Order, the County will not seek any appellate review of the ruling, decision or injunction of this Court in Inyo County Superior Court Case Number 12908.

§ 7.01.010. Declaration of findings and purpose.

The board of supervisors does find and declare as follows:

A. The groundwater basin of Owens Valley has historically supplied the people and land of Inyo County with spring flow water and a high water table, which has sustained vegetation and wildlife in an otherwise desert environment.

B. The groundwater basin of the Owens Valley forms a significant water resource of the State of California, which must be managed in trust for the benefit of the state's entire population and must be conserved so that it may be perpetually placed to the reasonable and beneficial use of all its potential users.

C. The groundwater basin of the Owens Valley must be managed and operated for the maximum long-range benefit of the environment, as well as for municipal and agricultural uses, by removing and mitigating all adverse environmental effects caused by groundwater extraction and surface water diversion by whatever feasible means are available.

D. In recent years the groundwater basin of the Owens Valley has not been managed in consonance with the findings declared in subsections A, B and C of this section, as a consequence of which unnecessary and excessive drawdown of the groundwater table has occurred. Together with other adverse environmental effects, producing detriment to the people, health and economy of the county, the lowering of the water table has directly led to a loss of vegetation and indirectly to a reduction in irrigated acreage. As a consequence of the recent environmental changes, the California Department of Water Resources in Bulletin 118-80 has identified the Owens Valley as an area of special concern.

E. Inyo County has a paramount right and duty to govern the management and extraction of resources within its jurisdiction in order to protect the health, welfare and safety of the citizens of Inyo County.

F. In order to protect its people, environment and economy, the county must adopt a systematic regulation of extractions from the groundwater basin of the Owens Valley; this regulation must consider environmental and economic factors in the area of origin and the area of use, coordinated use of surface and groundwater resources, and the implementation of water conservation and other feasible preferred alternatives to extraction.

G. To implement the systematic regulation of groundwater extractions, the county must undertake the preparation of a water management plan for both groundwater and the inherently integrated surface water resources of the Owens Valley.
