Abstract
This paper describes the design, rationale and implementation of the Alcohol Access Component within the Community Trials Project of the Prevention Research Center, Berkeley, California (USA). The Alcohol Access Component was to reduce the concentration or density of alcohol outlets in each experimental community by a combination of local zoning and land-use planning approaches which was an effect to occur over several years. During the time of this trial, local regulations of alcohol outlets and public sites for drinking were changed in all three experimental communities. The amount of such alcohol police change exceeded the goals for this component. (A)
