Moratorium on hemp cultivation
On November 17th, 2020, the Board of Supervisors voted to enact Ordinance No. 2020-28, an urgency interim ordinance imposing a 45 day moratorium on industrial hemp cultivation. On December 15th, 2020, the Board voted to enact Ordinance No. 2020-30, extending the moratorium until March 10th, 2021. While the moratorium is in effect, no new registrations for the cultivation of hemp will be issued, and current registrations will not be renewed upon expiration.
The purpose of the moratorium is to give the county time to develop a permanent ordinance that will provide local requirements for the cultivation of industrial hemp.
