L.A. Leads Cities in Scrubbing Duplicate Images From Public Databases — but the Job Is Far Than Done

The City of Los Angeles has quietly removed more than 340,000 duplicate photographs and scanned documents from its public-facing digital archives since January 2026, according to figures released last month by the Bureau of Contract Administration. The cleanup — driven partly by 2028 Olympic infrastructure deadlines and partly by Mayor Karen Bass's push to digitize permitting records for emergency housing projects — has made L.A. one of the more aggressive municipalities in the world when it comes to tackling what archivists call the "duplicate image problem." Other major cities, including London and São Paulo, are still largely in the planning stages of similar efforts.

The stakes are higher than they might appear. Duplicate images clog permit-review queues, slow down insurance assessments after disasters, and — critically for Los Angeles right now — complicate wildfire preparedness mapping when aerial survey photos are stored in multiple, conflicting versions across different city departments. After the January 2025 fires tore through Altadena and Pacific Palisades, city auditors flagged redundant drone imagery as one factor that had slowed damage-assessment workflows in the immediate aftermath.

What L.A. Is Actually Doing

The primary effort runs through the Department of City Planning's Digital Services division, which is based in the Civic Center complex on Spring Street in downtown Los Angeles. Starting in February 2026, the division deployed automated deduplication software across its GeoHub platform — the same mapping system that feeds data to the Los Angeles Fire Department's pre-incident planning tools. The Bureau of Engineering, which manages infrastructure drawings for everything from the Sixth Street Viaduct maintenance records to storm drain schematics in Boyle Heights, is running a parallel cleanup on a separate contract awarded to a vendor through a competitive bid process that closed in March.

The Los Angeles County Assessor's Office, a distinct agency from the city but whose parcel photography overlaps heavily with city permit records, announced in April that it had identified roughly 180,000 duplicate parcel images going back to digitization efforts that began in 2009. Those records are scheduled for consolidation by the end of the third quarter of this year. The Assessor's office has estimated the redundant storage was costing the county approximately $2.1 million annually in cloud infrastructure fees — a figure cited in its April budget presentation to the county Board of Supervisors.

How Other Cities Compare

London's Government Digital Service published a white paper in May 2026 acknowledging that duplicate imagery across the Greater London Authority's planning portal had reached what the document described as an unmanageable volume, but the GLA has not yet awarded a remediation contract. São Paulo's municipal government launched a pilot deduplication program in two of its 96 subprefectures in late 2025 but has not announced a citywide rollout timeline. Tokyo, which faced similar pressure before its 2020 Olympics cycle, completed a major archive consolidation in 2019 and is often cited by digital records specialists as the benchmark — though Tokyo's highly centralized administrative structure made the task structurally easier than it would be in a fragmented system like Los Angeles County, where dozens of agencies maintain separate databases.

New York City's Department of City Planning has been running a deduplication initiative through its NYC Open Data portal since 2023, and has publicly logged the removal of more than 600,000 redundant files — a higher raw number than Los Angeles, though New York's archive is also considerably larger and older. The comparison is imperfect, but it gives a rough sense of where L.A. sits: ahead of most cities globally, trailing New York on volume processed, and meaningfully ahead of European and Latin American counterparts that are still scoping the problem.

For Angelenos with a practical stake in this — anyone pulling building permits in Koreatown, submitting insurance claims on fire-damaged property in the San Fernando Valley, or working on an Olympic venue bid near the Sepulveda Basin — the cleanup has real consequences. The Department of City Planning says its permit-processing times for digital submissions have dropped by an average of four business days since the GeoHub deduplication began, though that figure covers only a portion of the total archive work. The full consolidation is expected to wrap up by the first quarter of 2027, well ahead of the Olympic torch arriving in Los Angeles in the summer of 2028.
