Sec. 10A.13.010 - Definitions.¶
Unless the context otherwise requires, the following definition in this section govern the construction of this Ordinance in order for more effective interpretation and enforcement.
AGRICULTURAL LAND. Shall mean those land areas of the County specifically classified and zoned as Agricultural, Rangeland, Forestland, or Timberland Preserve within which agricultural, timber growing and related activities are to be encouraged and protected.
AGRICULTURAL OPERATION. Shall mean and include, but not be limited to, the cultivation and tillage of the soil, animal husbandry, the production, cultivation, growing, harvesting and processing of any agricultural commodity including horticulture, timber or apiculture, the raising of livestock, fish or poultry, and any acceptable cultural practices performed as incident to, or in conjunction with, such farming operations, including preparation for market, delivery to storage or market, or to carriers for transportation to market.
FARM OPERATION. Shall mean those activities normally conducted in the pursuit of agricultural operations which includes the farming of trees for commercial purposes.
(Ord. No. 3414, adopted 1983.)
Sec. 10A.13.020 - Policy.¶
It is the declared policy of this County to conserve, protect and encourage intensive agricultural production. Where nonagricultural land uses extend into agricultural areas or exist side by side, agricultural operations have often become the subject of nuisance complaints. As a result, agricultural operations are sometimes forced to cease or curtail operation, and many others are discouraged from making investments in farm improvements. It is the purpose and intent of this section to reduce the loss to the County of its agricultural resources by limiting the circumstances under which agricultural operations may be considered a nuisance. This section is not to be construed as in any way modifying or abridging State law as set out in the California Civil Code, Health and Safety Code, Fish and Game Code, Food and Agricultural Code, or Division 7 of the Water Code, relative to nuisances, but rather is only to be utilized in the interpretation and enforcement of the provisions of this code and County regulations.
No existing or future agricultural operation or any of its appurtenances, conducted or maintained for commercial purposes, and in a manner consistent with proper and accepted customs and standards, shall become or be a nuisance, private or public, for adjacent land uses in or about the locality thereof after the same has been in operation for more than three (3) years, when such action was not a nuisance at the time it began; provided that the provisions of this subsection shall not apply whenever a nuisance results from the negligent or improper operation of any such agricultural operation or its appurtenances.
(Ord. No. 3414, adopted 1983.)
Sec. 10A.13.030 - Findings.¶
The Board of Supervisors of Mendocino County finds that it is in the public's interest to preserve and protect agricultural land and oper-ations within the County of Mendocino and to specifically protect these lands for exclusive agricultural use. The Board of Supervisors of Mendocino County also finds that residential development adjacent to agricultural land and operations often leads to restrictions on farm operation to the detriment of the adjacent agricultural uses and economic viability of the County's agricultural industry as a whole. The purposes of this Chapter, therefore, are to promote the general health, safety and welfare of the County, to preserve and protect for exclusive agricultural use those lands zoned for agricultural use, to support and encourage continued agricultural operation in the County, and to forewarn prospective purchasers and residents of property adjacent to or near to agricultural operation of the inherent potential problems associated with such purchase of residence including, but not limited to, the sounds, odors, dust, and chemicals that may accompany agricultural operations.
(Ord. No. 3414, adopted 1983.)
Sec. 10A.13.040 - Disclosure.¶

Mendocino County has established zoning for agricultural land which sets as a priority the agricultural use of the lands included therein, and residents of such property, or within zoned areas, should be prepared to accept such inconvenience or discomfort as normal and necessary to farm operation.
