Thirteen measures were approved for the ballot through voter petitions. Four initiatives pitted environmentalists against the agriculture and timber industries on issues concerning the use of pesticides and prohibitions on clear-cutting old-growth forests. Proposition 136, requiring a two-thirds voter approval for any tax increases earmarked for specific purposes, competed against three other proposals to raise various taxes. Other tax-related propositions involved an increase in taxes on alcoholic beverages, the proceeds of which would go to drug and alcohol treatment programs, emergency medical care, and mental health services; and a proposed sales tax increase to fund anti-drug education and law enforcement efforts. Two rival initiatives would limit the terms of State officeholders. Several bond issues were proposed for new prison construction, county jails and juvenile facilities, and county courthouses.
