The Parkway is part of our urban forest and the lack of care for it increases the concerns about crime in the Lower Reach of the Parkway (from Discovery Park to Cal Expo) due to the overgrown environment that has allowed long-term illegal camping by the homeless (which includes criminals and registered sex offenders –the sex offenders were removed after we brought their presence in the Parkway to the attention of the County Board of Supervisors and Sacramento City Council—) see our posts here and here.
Being able to bring the principles of crime prevention through environmental landscape design (primarily thinning out and opening up sight lines) to increase public safety, into that region would be of great help.
Here are a couple links to information on the subject, one from Wikipedia and one to an academic paper.
