Seattle’s Hidden Surveillance Grid: A New Guide Maps the City’s Data Infrastructure

A digital guide detailing a 1.3-mile walking tour of surveillance infrastructure in downtown Seattle has been published by coveillance.org. Originally developed through pilot workshops in October 2019 by the Tech Equity Coalition in partnership with the ACLU of Washington, the resource maps hidden layers of the "smart" city. It examines six primary categories of surveillance technology: security cameras, Amazon Go stores, automated license plate readers (ALPRs), Acyclica Wi-Fi tracking devices, the Washington State Fusion Center, and NSA wiretapping peering sites. The guide highlights data collection mechanisms, social implications for privacy and civil liberties, and the lack of regulatory oversight.

The guide provides specific operational details for each technology, including addresses, physical appearances, and technical mechanisms. For ALPRs, the text states the Seattle Department of Transportation (SDOT) has at least 99 stationary units, while the Seattle Police Department (SPD) has 19 vehicles equipped with mobile ALPRs. It claims SDOT’s stationary ALPR system collects approximately 37,000 license plates in 24 hours, equating to 13.5 million scans annually.

Regarding the Acyclica device, the guide explains it tracks mobile devices by listening for probe packets containing MAC addresses. The Washington State Fusion Center (WSFC) is described as seating 15-30 intelligence officers, linked to the State Intelligence Network and having physical and digital access to the FBI’s Field Intelligence Group. The guide references the 2007 arrest of anti-war protester Phil Chinn as a notable case involving the fusion center.

An AT&T peering site at 1110 3rd Ave is identified as one of eight wiretap rooms in the NSA’s FAIRVIEW surveillance program. The resource notes that while the WSFC does not store most data itself, it negotiates agreements for remote access to existing databases, including those from private entities. The guide argues that this fractured chain of command and lack of transparency make it difficult to expose political policing or ensure accountability.

The publication serves as a field guide for citizens to "spot" surveillance technology in the wild, categorising each site by address, appearance, function, and technical operation. It emphasises that data collected by these systems often escapes its original context, potentially being shared with law enforcement, private corporations, or used for predictive analytics without public consent. The guide remains a work in progress, inviting feedback and adaptation for other cities.
