It’s going to be quite a primary June 7 for San Jose voters, especially if California for once matters in the presidential nominations. Several city council seats have no long-time incumbents running, and candidates are swarming.

We suggest getting an early start on those choices with Measure C, the marijuana zoning initiative. It’s easy. Just Say No.

Seriously.

The measure floated by medicinal pot club interests would allow them to locate in any agricultural, commercial pedestrian, commercial neighborhood, industrial park, light industrial, heavy industrial zoning districts, and certain planned development zoning districts — even near preschools . This would pretty much restore the chaos that existed when more than 100 clubs sprang up all over town several years ago, prompting the city to tax and regulate them, including rules about where they can locate.

The measure would set a dangerous precedent. Other businesses could bankroll campaigns to get voters to change zoning in their favor. Your neighborhood could be the loser.

This is not about whether you think marijuana should be available for medical purposes, as we do. Nor does it matter whether you think pot should be legal for recreational use. Most people believe selling alcohol should be legal, but it doesn’t mean the Shots ‘n’ Beer Saloon should be able to locate anywhere it wants.

San Jose is painted as a villain by the clubs, but it has struggled to make this industry work while most other Silicon Valley cities took the easy way out and just banned the collectives. The city conducted long, careful deliberations before deciding how to limit locations, and it adjusted some rules to be compatible with the regulations California finally adopted last year.

San Jose was prompted to act after city council members and police were bombarded with complaints from neighbors of the clubs who saw unsavory behavior, including kids coming and going after school and people toking up outside the premises. Officials learned some businesses didn’t want the clubs near them even in office parks, giving a bad impression to clients.

So the city limited where the clubs could go, set licensing requirements and asked voters to approve taxing them for enforcement costs. By the end of last year, 16 had met city requirements to operate. It’s the others that want to roll back zoning to pretty much anything goes.

At least one proposition to legalize pot for recreational use will be on the fall ballot, although voters have rejected these before. Fortunately, the state appears ready to regulate the business, taking lessons from Colorado and other pioneers in legalization. In the meantime, it’s important for San Jose to control where pot clubs can locate. Vote no on Measure C.
