Sec. 6.35.010 - Title.¶
This Chapter shall be known as and may be referred to in all proceedings as the "Mendocino County Right to Industry Ordinance".
(Ord. No. 4319, 1-7-2014)
Sec. 6.35.020 - Purpose.¶
The purpose of this ordinance is to enhance the prospects of growth and stability for Mendocino County's businesses that are located within the County's established industrial zones: I-1 (Limited Industrial), I-2 (General Industrial), I (Coast Industrial), and P-1 (Pinoleville Industrial). The County recognizes that industrial interests operating within the County may be endangered by residents or other businesses located nearby and who seek to abate what they deem a nuisance arising from operations by said industrial interests.
This ordinance seeks to reduce nuisance complaints by disclosing to existing and potential property owners of land zoned "Industrial Land", or which may be located within three hundred (300) feet of land zoned "Industrial Land", that they are affected by this ordinance. Furthermore, this ordinance seeks to clarify the circumstances in which an industrial operation may ultimately be declared a nuisance and ordered to change operations, after an initial investigation, declaration of a potential violation, and review of the evidence by a County Enforcement Officer or a Hearing Officer.
(Ord. No. 4319, 1-7-2014)
Sec. 6.35.030 - Policy.¶
Pursuant to the Planning Principles of the Mendocino County General Plan, it is the declared policy of this County to encourage sustainable economic growth. This objective directly correlates with the success of Mendocino County's industrial operations located within its industrially zoned districts. Where non-industrial land uses extend into industrial areas or exist side by side, industrial operations may become the subject of nuisance complaints. As a result, industrial operations could be forced to cease or curtail operation, and others could be discouraged from making investments and improvements.
It is the purpose and intent of this ordinance to reduce the loss to the County of its employment base by limiting the circumstances under which industrial 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, Division 7 of the Water Code, or Government 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 industrial business or any of its appurtenances, consistent with the industrial operation provisions of the Mendocino County Zoning Code, conducted or maintained for commercial purposes, and in a manner consistent with applicable land use and environmental laws and regulations, 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 a negligent or improper operation of any such industrial operation or its appurtenances.
(Ord. No. 4319, 1-7-2014)

The purposes of this Chapter, therefore, are to promote the general health, safety and welfare of the County, to preserve and protect for exclusive commercial use those lands zoned for industrial use, to support and encourage continued industrial operation in the County, and to disclose to prospective purchasers and residents of property adjacent to or near to industrial operation of the inherent potential ramifications associated with such purchase of residence including, but not limited to, the sounds, odors, dust, and chemicals that may accompany industrial operations.
