Editor's note— Ord. No. 349-D, adopted May 8, 2018, amended ch. 18.175 in its entirety to read as herein set out. Former ch. 18.175, §§ 18.175.010—18.175.060, pertained to medical marijuana cultivation, and derived from Ord. No. 349-C, §§ 1A—C, 2A, 3, 4, adopted Dec. 16, 2013.

18.175.010 - Legislative findings.

The board of supervisors finds as follows:

In 1996, the voters of the State of California approved Proposition 215 which was codified as Health and Safety Code Section 11362.5, and entitled "The Compassionate Use Act of 1996."

The intent of the Act was to enable persons who are in need of marijuana for medical puiposes to legally obtain and use it without fear of criminal prosecution under limited, specified circumstances.

This ordinance is enacted, consistent with Health and Safety Code Section 11362.7 et seq., to protect the public health, safety and welfare of Modoc County residents from the negative effects of commercial marijuana cultivation, marijuana processing, and marijuana dispensaries.

In 2004, Senate Bill 420 was enacted, codified as California Health and Safety Code Section 11362.7, et seq. and entitled the "Medical Marijuana Program Act," to clarify the scope of the Act and allow cities and counties to adopt and enforce rules and regulations consistent with its provisions.

On October 9, 2015, Governor Jerry Brown signed the "Medical Marijuana Regulation and Safety Act" ("Act") into law. The Act became effective on January 1, 2016, and contains new statutory provisions regarding marijuana cultivation and distribution.

The Act does not supersede or limit local authority for local law enforcement activity, enforcement of local ordinances, or enforcement of local permit or licensing requirements regarding marijuana (Business and Professions Code Section 19315(a));

The Act does not limit the authority or remedies of a local government under any provision of law regarding marijuana, including but not limited to a local government's right to make and enforce within its limits all police regulations not in conflict with general laws (Business and Professions Code Section 19316(c);

On November 8, 2016, California Voters approved Proposition 64 allowing for the adult use of marijuana for recreational purposes, without the need for a doctor's recommendation, and set limits on the amount of marijuana that may be possessed and where marijuana may be consumed.

State law allows local governments to enact ordinances expressing their intent to prohibit the commercial cultivation of marijuana and their intent not to administer a conditional permit program pursuant to Health and Safety Code Section 11362.777 for the cultivation of marijuana (Health and Safety Code Section 11362.777(c)(4);

The board of supervisors finds that this chapter: (1) expresses its intent to prohibit the commercial cultivation of marijuana in the County and to not administer a conditional permit program pursuant to Health and Safety Code Section 11362.777 for the cultivation of marijuana in the county; (2) exercises its local authority to enact and enforce local regulations and ordinances, including those regarding the permitting, licensing, or other entitlement of the activities prohibited by this chapter; (3) exercises its police power to enact and enforce regulations for the public benefit, safety, and welfare of the county and its community; (4) expressly prohibits the commercial cultivation, sale, dispensing of medical marijuana in the county; and (5) regulates personal cultivation for medical and recreational users consistent with state law.

The county has adopted a zoning ordinance identified as title 18 (zoning) of the Modoc County Code.

That prior to the enactment of this section, there were no adopted rules and regulations specifically applicable to the cultivation of marijuana and the lack of such controls could lead to a proliferation of marijuana cultivation and the inability of the county to regulate this land use.

That based on the adverse secondary impacts that have occurred and the lack of any regulatory program in the county regarding the cultivation of marijuana; it is reasonable to conclude that negative effects on the public health, safety, and welfare may occur in the county as a result of the proliferation of large-scale, unregulated marijuana cultivation and the lack of appropriate regulations governing the establishment and operation of such land uses.

That unregulated large scale marijuana cultivation has rapidly increased in the county which increases the risk of criminal activity and the degradation of the natural environment.

That some marijuana grows are occurring on unattended private lands as well as residential areas without owner consent and have been the subject of criminal activities and violations that have threatened the safety and property of nearby land owners and their families.

That in some cases, people protecting the marijuana cultivation operations have been armed and constitute a threat to others who may attempt to use land in the vicinity of the operations.

That some growers are indiscriminately using chemicals and cultivation practices that are causing damage to wildlife and contamination to soil and water sources.

That some growers are clearing land without regard to the consequences resulting in the removal of vegetation, including timber, which leads to soil erosion and siltation of waterways.

That indoor cultivation of substantial amounts of marijuana within a residence presents potential health and safety risks to those living in the residence, especially to children, including risk of fire from lighting systems, exposure to chemicals and exposure to property crimes as the plants themselves may be an attractive nuisance.

Children are particularly vulnerable to the effects of marijuana use and the presence of marijuana plants in close proximity to sensitive areas where children might be present could present an unreasonable hazard or adversely affect the health, safety and welfare of children.

That the county has a compelling interest in protecting the public health, safety and welfare of its residents and businesses, in preserving the peace and quiet of the neighborhoods, and in providing access to marijuana consistent with the intent of the Act.
