Editor's note— Ord. 842, § 1, adopted Dec. 4, 2017, amended Ch. 8.35 in its entirety. The former chapter derived from Ord. 803, § 1, 8-11-2011.
8.35.000 - Findings and Declarations¶
A. The Federal Controlled Substances Act, 21 U.S.C. § 801 et seq., classifies marijuana as a Schedule 1 Drug, which is defined as a drug or other substance that has a high potential for abuse, that has no currently accepted medical use in treatment in the United States, and that has not been accepted as safe for use under medical supervision. The Federal Controlled Substances Act makes it unlawful under federal law for any person to cultivate, manufacture, distribute or dispense, or possess with intent to manufacture, distribute or dispense marijuana.
B. On November 8, 2016, California voters passed Proposition 64, the Adult Use of Marijuana Act ("AUMA"). AUMA legalizes the cultivation, commercial sale, and possession of recreational cannabis for adults age twenty-one and older under state law. AUMA prohibits the city from entirely prohibiting personal cultivation for adult use of cannabis inside a private residence; however, it does allow the city to impose reasonable regulations on the practice.
C. The city council finds that cultivation of cannabis for adult use can adversely affect the health, safety, and well-being of city residents. Reasonable citywide regulations are proper and necessary to avoid the risks of criminal activity, access by persons under the age of twenty-one, degradation of the natural environment, malodorous smells, and indoor electrical fire hazards that may result from such activities.
D. The city council believes that the regulations specified below for the cultivation of cannabis for personal uses are reasonable and allowable under AUMA.
