Craig Brooks, Sheriff’s Office Captain, shared they are continuing with efforts to combat
illegal dumping, but haven’t been able to do targeted enforcement with the overtime due to
staffing issues. Stacey Grassini, Assistant District Attorney, highlighted that the amount of
enforcement done now has increased significantly then what it was 6 years ago and they
will continue to move forward. Supervisor Burgis asked how we are holding the illegal
dumpers accountable. Stacey responded that it depends on the situation, but he knows there
is a lot of effort on the Sheriff’s side of things to follow up on these cases and sometimes
they can get dumpers to go back and pick up their waste. He further mentioned that if the
file case is fairly egregious, they get filed, and it’s a matter of leaning on the courts to enact
the punishment. Supervisor Scales-Preston asked how many people have been fined for
illegal dumping in 2024. Dylan Chiu showed the Contra Costa County Illegal Dumping
Dashboard to highlight the stats provided by the Sheriff’s and the District Attorney’s office.
From August 2024 to January 2025, there were 72 Mobile Citizen App reports for clean-up,
36 Litter/Illegal Dumping reports written, 14 Cases submitted to DA for filing, and 6
citation issues. In 2024, there were approximately 36 illegal dumping cases received by the
DA for review. Stacey clarified that his office only handles misdemeanor cases, which
involve more than one cubic yard of waste. Smaller violations are handled as infractions in
Traffic Court.
Fencing - Strategy #6
Chris Lau, Assistant Public Works Director of the Maintenance Division, shared they
installed 4,300 linear feet of fencing along 3 roadways which include San Pabo Dam Road,
Frank Canyon Road, and Crockett Blvd. The project cost about $350,000 and created a
physical barrier to prevent dumping.
Surveillance Cameras - Strategy #46
Chris Lau reminded the committee that 10 mobile surveillance units were first deployed in
September-October 2024. Most were initially in District 1, with redeployments every 90
days. They are currently in Districts 3 and 5. Each unit has three PTZ cameras monitored
24/7 by a private company using AI to set up alert zones. Units cost $2,500 per month or
$30,000 annually each.
Chris presented slide of what the video monitoring system looks like and the capabilities to
review old footage to gather evidence to send to the Sheriff’s Office.
Chris shared three videos with the committee. The first video shared was of a potential
illegal dumper pulling into the alert zone and throwing garbage off the side of the road. The
second video was of a vehicle pulling over to illegally dump on the side of the road which
led to the agent monitoring the camera to use the loudspeaker function to dissuade the
illegal dumper from dumping more trash. The last video showed another vehicle pulling
over to dump garbage under a freeway overpass and in this situation the cameras were able
to get a license plate. The information was provided to Sergeant Haley with the Sheriff’s
Office, who was able to contact the perpetrators and have them return to retrieve their
items. Supervisor Burgis asked if these cameras have helped with any other type of
investigation. Captain Brooks responded that he isn’t aware of these cameras helping, but
