Los Angeles Summer Night Lights Crime Prevention Program

Case Study | Community Benefits
Los Angeles Summer Night Lights Crime Prevention Program

Key Findings:

  • Gang violence can be reduced by keeping parks open and lit during peak summer night hours
  • Parks that are peak gang activity areas can be transformed into vibrant community spaces after dark with organized activities for at-risk youth and families

Program Details

The Office of Gang Reduction and Youth Development’s (GRYD) was created in 2007 to reduce gang-related violent crime. They determined that a lack of safe and accessible public space, oppressive economic conditions, and crowded housing situations created high levels of stress within families, potentially driving kids to hang out on streets and increasing their likelihood of becoming involved in unhealthy activities or becoming victims of violence and crime. To mitigate this problem, they designed Summer Night Lights (SNL), a program to aims to reduce violent crime while promoting peaceful, positive, and healthy activities.

Beginning with 8 Los Angeles parks in 2008, Summer Night Lights has expanded to 24 sites in 2010 and to 32 sites in 2013. In 2008, the Summer Night Lights program was credited with reducing gang violence to its lowest level since 1967. The city matched donations from philanthropic institutions to fund a range of entertainment, recreation, education, and artistic activities that take place during peak gang activity hours in the summer. All activities are free, and each SNL location is open from 7 – 11 PM on Wednesdays through Saturdays from late June through early August, and on Fridays and Saturdays throughout the remainder of August. These activities serve as a diversion from criminal activities for youth living in these areas and help build social connections that replace gangs. Gang intervention workers are assigned to moderate gang disputes and ensure that there are cease-fires at SNL parks. This strategy has become a nationally recognized success story for both reducing violence and building communities for safer cities. Formal evaluations of the Summer Night Lights program in 2009 and in 2011 can be found on the Urban Institute website.
