(Ord. # 150-2011) 10-7. COMMERCIAL MEDICAL MARIJUANA CULTIVATION AND CULTIVATION ON VACANT PROPERTIES, AND LIMITING CULTIVATION AMOUNTS. 10-7.1 Findings. a. The existing commercial and medical marijuana cultivation sites on vacant properties and within community areas and other incorporated areas of the City of Clearlake, along with the potential establishment of additional such cultivation sites and excessive cultivation of amounts by individuals poses a current and immediate threat to public health, safety or welfare. If medical marijuana cultivation, in significant quantities, is allowed to proceed without appropriate review of location and operational criteria and standards, the cultivation could continue to result in ever increasing adverse secondary effects on neighborhoods and the City that present a clear and immediate danger to the public health, safety, and welfare, and to the natural environment. b. The failure to adopt this ordinance, therefore, may result in significant irreversible change in the character of the community and the neighborhood surrounding any commercial and/or large marijuana cultivation site or cultivation on vacant properties and in residential zones; may result in further environmental damage related to stormwater pollution, groundwater contamination and loss of wildlife habitat; may increase the potential for catastrophic wildland fires due to the practices of growers on undeveloped properties, and; may contribute to blight and further decrease of property values for nearby residents, and; may result in increased criminal activity endangering the citizens of City of Clearlake.
