Flock Safety Automated License Plate Reading (ALPR) Camera Installation ProjectThe City of Santa Rosa is initiating the installation of Flock Safety automated license plate reading (ALPR) cameras across multiple public right-of-way locations to enhance law enforcement capabilities in identifying vehicles linked to criminal activity. The project involves mounting ALPR cameras and integrated solar power systems onto existing traffic signal or streetlight poles where feasible, and installing new breakaway support poles with small concrete foundations in areas lacking suitable infrastructure. These cameras are designed to operate continuously, capturing license plate data to assist the Santa Rosa Police Department in investigations and proactive public safety efforts. The system is intended to benefit both law enforcement and the broader community by supporting crime deterrence, increasing response efficiency, and improving overall safety throughout the city. All work will be performed within Santa Rosa, California, specifically in the 95409 zip code area, with no set-aside requirements or procurement restrictions specified. The project is forecasted and not yet awarded, with primary contact information provided through Chief of Police John Cregan, who can be reached via email or phone for inquiries. The initiative reflects a targeted investment in technology-driven public safety infrastructure, aligning with the city’s broader goals to modernize policing tools and strengthen community security through data-enabled surveillance systems that comply with public space usage standards.
