Campbell voters will see three measures on the ballot for an April 25 special election regarding medical marijuana. Two measures are directly competing with each other, while one is a tax measure.

Measures A and C are city measures, while Measure B is a citizen’s initiative. All three measures focus on the dispensing, delivery and cultivation of medical marijuana within the city.

Measure A asks voters to allow the city to implement a business license tax on marijuana businesses at an initial rate of 7 percent with a maximum of 15 percent of gross receipts.

According to the city, an estimated $130,000 to $260,000 could be raised annually from the gross receipts tax. Money from the tax would go toward city services such as police, fire and code enforcement.

Measure C asks voters to decide if the city should be given time to study traffic, neighborhood and safety issues before it decides to allow medical marijuana dispensaries. If passed, the measure would put a moratorium on dispensaries until April 1, 2019.

Measure C would also give the city discretion to allow dispensaries after April 1, 2019, but to require them to be at least 100 feet from residential properties and 600 feet from child care facilities, schools, parks, community centers and other dispensaries.

Measure C is competing directly with Measure B, which began as a citizen initiative in March when the city approved an ordinance prohibiting the delivery, dispensing and cultivation of medical marijuana.

The measures asks voters to require the city to license up to three medical marijuana dispensaries within manufacturing and planned development zones. It asks voters to require the delivery of medical marijuana to patients throughout the city. If passed, Measure B would allow patients to cultivate up to 100 square feet of marijuana, and caregivers could cultivate up to 500 square feet of marijuana without a license.

Kale Schulte, the citizen who submitted the initiative petition and spokesman for Keep Campbell Green, declined to comment.

On Jan. 12 the council amended the same ordinance petitioners are seeking to change to allow delivery from licensed dispensaries located in other municipalities and cultivation of up to six marijuana plants for medicinal use. The council approved the change to address patients’ need to access medical marijuana.

The April 25 special election will only establish regulations on medical marijuana, which is regulated differently than recreational marijuana. The city does not prohibit the use of medical marijuana.

Each measure requires a simple majority vote to pass, according to the Santa Clara County Registrar’s Office.

The last day to register to vote for the special election is April 10, according to the Registrar.

Voters can cast their ballots beginning March 27 by visiting the Registrar of Voters office at 1555 Berger Drive in San Jose.

Voters can also request a vote-by-mail ballot until April 18. Ballot drop-off locations will be at the Campbell Library, 77 Harrison Ave., and at city hall, 70 N. First St.

Vote-by-mail ballots will be mailed out to voters beginning March 27. Arguments and rebuttals for each of the measures are available online.
