MARTINEZ — The City Council will host a workshop Sept. 6 to discuss how the city should handle “the nuances and complexity of laws surrounding cannabis, both medical and recreational,” from both policing and city policy angles.

David McPherson, cannabis compliance director for Southern California-based consultant HdL Companies, is scheduled to make a presentation about considerations cities should make as changes unfold with laws concerning both medicinal and recreational marijuana.

In December, the City Council extended by 10 months three urgency marijuana ordinances to allow time for thorough research on city’s legalization of marijuana options.

Such urgency ordinances are intended to give a local community control of marijuana-related activities until new state regulations are clear, after which point more complete ordinances would replace them. Wednesday’s workshop comes just ahead of that 10-month extension expiring; however, the emergency ordinances could be extended for another year.

The Martinez urgency ordinance was adopted to conform with California state Proposition 64, passed in November, to prohibit outdoor marijuana growth, and establish requirements for indoor growth. Medical marijuana use, with some restrictions, is already allowed in Martinez, but Prop. 64 allowed the use, indoor cultivation and sale of recreational marijuana.

The questions faced by city governments and police departments are many, ranging from landlords’ rights on property where medicinal or recreational marijuana can be grown, as per Proposition 64; and whether the city wants to allow businesses that sell either kind of marijuana.

At the end of Wednesday’s presentation, the council could direct the city staff in any of a number of directions, based on how much, or little, marijuana cultivation, sales and use the council wants to host.

Wednesday’s meeting begins at 7 p.m. at Martinez City Hall, 525 Henrietta Ave. (at Alhambra Avenue).
