Off-campus parties that foster underage and high-risk drinking and become a nuisance to neighbors are often a sore spot when it comes to town-gown relations. Responding to these parties is leading communities to adopt new measures and enforcement strategies to reduce a range of problems faced by students and residents alike. While many policy and enforcement strategies have been identified and implemented at colleges and universities and in surrounding communities aimed at reducing underage and/or unruly house parties, little research has been conducted to identify the effectiveness of specific measures. Two separate studies reported in a special college drinking supplement of the "Journal of Studies on Alcohol and Drugs" (July 2009) developed programs in which colleges worked closely with their surrounding communities, using measures such as increased police patrols in problem neighborhoods and raising student awareness of their responsibilities as community residents.
