2024 Surveillance Technology Annual Report | 3 Office of Strategic Planning and Community Development 1. A description of how surveillance technology has been used, including whether it captured images, sound, or information regarding members of the public who are not suspected of engaging in unlawful conduct: The drone has been used to take pictures and videos focused on public spaces, and street intersections. Drone footage is recorded only from 100 ft or higher, so no sound of conversations of any kind is captured. Images and videos include residents only if they are in public spaces and in most cases, they are not identifiable due to the distance. 2. Whether and how often data acquired through the use of the surveillance technology was shared with local, state, and federal, the name of any recipient entity, the type(s) of data disclosed, any legal standard(s) under which the information was disclosed, and the justification for the disclosure: No data from the drone has been shared with law enforcement or any other entity outside of OSPCD. 3. A summary of community complaints or concerns about the surveillance technology, if any: None 4. The results of any internal audits, any information about violations of the surveillance use policy, and any actions taken in response other than to the extent that such inclusion would violate the privacy rights of an employee of the city: None 5. Whether the surveillance technology has been effective at achieving its identified purpose: Yes. The videos and images collected have been a helpful resource in OSPCD’s planning efforts. Division or Unit (if applicable): Planning, Preservation & Zoning Compliance Officer: Alan Inacio, Senior Accountant, OSPCD Submitted by: Dan Bartman, Interim Director of Planning, Preservation, & Zoning Date: 1/23/25 Surveillance Technology: Video/Photography Drone

2024 Surveillance Technology Annual Report | 4 6. The number of public records requests received by the city seeking documents concerning surveillance technology approved during the previous year: None 7. An estimate of the total annual costs for the surveillance technology, including personnel and other ongoing costs, and what source(s) of funding will fund the technology in the coming year, if known: Training of a new pilot will be necessary in the coming year but then only staff time in utilizing it. 8. Whether the civil rights and liberties of any communities or groups, including communities of color or other marginalized communities in the city are disproportionately impacted by the deployment of the surveillance technology: Since the purpose of this technology is not to track individuals in any capacity or to be utilized in any law enforcement effort, and since this technology has been used consistent with the stated purpose and with the City’s Surveillance Technology Use Policy to capture arial-view images of public spaces for planning purposes, we do not believe this technology has a negative impact on the civil rights and liberties of individuals or groups. 9. A disclosure of any new agreements made in the past 12 months with non-city entities that may include acquiring, sharing, or otherwise using surveillance technology or the surveillance data it provides: None

2024 Surveillance Technology Annual Report | 5 Parking Department Division or Unit (if applicable): Parking Department, Compliance Compliance Officer: Suzanne Rinfret, Director of Parking Submitted by: Suzanne Rinfret, Director of Parking Date: 1/23/25 Surveillance Technology: Safety Stick 1.

Whether the surveillance technology has been effective at achieving its identified purpose: The technology has been effective, we are seeing more compliance in the 4 areas where the Safety Sticks have been deployed. There are 16 total Safety Sticks at select bus stops, bus lanes and crosswalks in Davis Square and Magoun Square. The Safety Sticks contribute to our Vision Zero goals by allowing the bus to pull up to the curb rather than stopping in the lane of traffic; allowing safe passage on/off busses; allowing full vision for drivers to see pedestrians in the crosswalk to avoid hitting anyone; and allowing the bus to travel smoothly through the square which increases reliability of public transportation.

For Cellular based 911 calls, Advanced/Next Gen 911 has provided callers locations based on cell tower locations. During the course of the previous year, we have also requested cellular providers ping subscribers phones to get a more accurate location of the caller. The reasons for these requests include the fact that the caller may be in imminent danger, the caller is a potential suicide risk, or the caller is the victim of an ongoing crime. The texting feature of the 911 system also allows access to the location of the phone that sent a 911 text. This technology does not capture images and does record the voice communications of the caller and the E911 operator. 2.
