Thank you for reporting! The Police Department's Community Service Section (CSS) has opened a case for this issue. CSS has one part-time and three full-time employees who are responsible for addressing all quality of life concerns, supporting Neighborhood Watch groups, and working with the Neighborhood Law Program and Code Enforcement to address distressed and dangerous properties. We work hard to investigate each report in a timely manner, and will investigate this report as soon as we possibly can. Please keep in mind there is a lengthy process to remove illegal encampments. If you have any questions, please call our office at (707) 553-7218.

If you witness any suspicious or criminal activity that requires an immediate response, please call 9-1-1.

Municipal city code 8.4 0.120. Use or occupancy of motor vehicles for living purposes prohibited. It is unlawful for any person or persons to occupy or use any motor vehicle for living purposes upon any street, alley, lane, Highway, municipal offstreet parking lot or other public space, or upon any lot, peace, parcel or tract of land within the city except as provided in chapter 7.96 of the Vallejo municipal code.
If you read the exception to the code 7.96.020, these people do not meet any criteria for the exception of living in your vehicle. There's absolutely nothing protecting them from being removed as far as I can see.

I did notice that, I'm glad someone reported it

They got ran out of the College Park a few weeks ago. Keep em' moving!
