The Baltimore Pre-Release Unit partners with other government agencies, community groups, and nonprofits to help them accomplish jobs that might otherwise not get done due to limited resources and funding. Projects range from community revitalization efforts to projects that are improving the sustainability of Maryland’s natural resources.

The flagship restorative justice program, Public Safety Works (PSW), provides employment skills as well as an opportunity for offenders to give back to the community they have harmed.
