How Boston's City Archives Ended Up With Thousands of Duplicate Photographs — and What It's Doing About It

Boston's city government is sitting on a problem that has been quietly compounding since at least the early 2000s: thousands of duplicate photographs embedded in public-facing documents, planning reports, and digital archives maintained by agencies ranging from the Boston Planning Department to the MBTA's communications office. The issue came to a head this spring when a citywide audit of digital asset management systems — ordered as part of Mayor Michelle Wu's broader push to modernize municipal infrastructure — flagged redundant image files occupying an estimated 40 percent of allocated storage across several departments.

The timing matters. Boston is in the middle of an aggressive push to digitize housing records tied to developments in Jamaica Plain and Dorchester, two neighborhoods at the center of the city's production targets under the Wu administration's housing agenda. Duplicate images embedded in environmental review filings and community meeting presentations have slowed the indexing process, according to city procurement documents reviewed by The Daily Boston. When the same photograph of, say, the Neponset River Greenway appears under four different file names in three different folders, automated cataloguing systems flag conflicts — and staff have to intervene manually.

A Problem Built Over Two Decades

The roots of the duplication backlog stretch back to a structural gap in how Boston agencies historically handled photographs. Before 2012, there was no unified digital asset management policy for municipal departments. Individual offices — Public Works, the Environment Department, the Boston Redevelopment Authority (since reorganized into the Boston Planning Department) — maintained their own file servers with their own naming conventions. When the city migrated to shared cloud storage between 2015 and 2018 under a contract with a third-party vendor, files were uploaded wholesale, with no deduplication layer applied first.

The result was predictable. A single aerial photograph of Dudley Square — taken during a 2009 planning study and later renamed Nubian Square — exists in at least six distinct copies across city servers, each tagged with different metadata, different resolution settings, and different access permissions. Staff at Boston City Hall on City Hall Plaza have known about the problem informally for years. The 2026 audit put numbers to it for the first time.

The MBTA, though a state agency rather than a city one, has a parallel problem. Marketing and communications staff pulling images for Green Line Extension announcements between 2019 and 2022 regularly downloaded and re-uploaded photographs from shared drives, creating layered duplicates. The agency's own internal review, completed in March 2026, found redundant files across its public affairs digital library dating to 2011.

What the City Plans to Do Next

The Wu administration's Office of Digital Innovation is now overseeing a phased cleanup program. Phase one, which began in April 2026, covers the Boston Planning Department's archive — roughly 180,000 image files, according to the procurement scope published on the city's supplier portal. A contract worth just under $340,000 was awarded to a vendor specializing in digital asset deduplication, with work expected to run through December 2026.

Phase two will extend the process to Public Works and the Parks and Recreation Department, which maintains extensive photographic records of green spaces including Franklin Park and the Rose Kennedy Greenway. That phase has no confirmed start date yet, though city budget documents submitted to the Boston City Council in May 2026 include a placeholder allocation of $210,000 for fiscal year 2027.

For residents and researchers who regularly pull documents from the city's public records portal — a resource heavily used by housing advocates, Northeastern University urban planning students, and biotech firms conducting environmental due diligence before signing leases in the Seaport — the practical upshot is a cleaner, faster-loading archive. Duplicate images inflate document file sizes, slow PDF rendering, and create mismatches when automated systems try to verify document integrity.

The city's Office of Digital Innovation has encouraged anyone who finds broken image links or flagged duplicates in public-facing documents to submit a report through the BOS:311 app. The cleanup is unglamorous work, but the backlog didn't build overnight — and neither will the fix.
