The document summarizes the efforts of the Safe Streets Coalition in Topeka, Kansas to reduce underage drinking through community partnerships and evidence-based strategies. Over 17 years, the 172-member coalition worked to establish law enforcement task forces, implement school prevention programs, conduct community awareness campaigns, and monitor outcomes through surveys. Key strategies included increased enforcement of underage drinking laws, the Positive Action prevention curriculum in schools, and public awareness events. Data shows reductions in past 30-day alcohol use, binge drinking, and increased perceptions of getting caught by police among youth. The success was attributed to long-term collaborative efforts across sectors using science-based approaches.
