This program provides financial assistance in the form of reimbursement grants up to $500,000 to help public entities accelerate the pace of cleanup, restore sites, and turn today’s problems into tomorrow’s opportunities. Widespread illegal dumping of solid waste adversely impacts Californians in many ways. Properties on which illegal dumping occurs lose economic value; create public health and safety and environmental problems; and degrade the enjoyment and pride in the affected communities. Abandoned, idled, or underutilized properties due to unauthorized dumping impact what were once the sources of economic benefits to a community. Many such properties have been abandoned or have owners who are unable or unwilling to pay the costs of cleanup.
