8.24.010 Legislative Findings and

Statement of Purpose A. The City Council finds that an ordinance is necessary to regulate the Cultivation of Marijuana or Cannabis in a manner that protects the health, safety and welfare of the community consistent with Proposition 64, also known as the Control, Regulate, and Tax Adult Use of Marijuana Act (“AUMA”). This Chapter is not intended to interfere with a patient’s right to medical Marijuana or Cannabis, as provided for in California Health & Safety Code Section 11362.5, nor does it criminalize medical Marijuana or Cannabis possession or cultivation by specifically defined classifications of persons, pursuant to state law. This Chapter is not intended to give any person unfettered legal authority to grow Marijuana or Cannabis; it is intended to impose zoning restrictions on the personal indoor Cultivation of Marijuana or Cannabis permitted under when it is authorized by California state law for medical or other lawful purposes. B. No part of this Chapter shall be deemed to conflict with federal law as contained in the Controlled Substances Act, 21 U.S.C. §§ 800 et seq., nor to otherwise permit any activity that is prohibited under that Act or any other local, state or federal law, statute, rule or regulation. (Ord. 801 § 1, 2013; Ord. 835 § 1, 2016; Ord. 856 § 1, 2017)
