L.A. Is Quietly Replacing Thousands of Duplicate Public Images — Here's How It Stacks Up Against Tokyo and London

Los Angeles city archivists have spent the better part of 18 months working through a backlog of roughly 340,000 duplicate image files sitting inside municipal databases — records that range from building permit photographs in the Department of Building and Safety to aerial survey shots used by the Bureau of Engineering. The cleanup, part of a broader digital asset management push tied to 2028 Olympic infrastructure deadlines, has become one of the more unglamorous but consequential technology projects city hall is quietly running this year.

The timing matters for a practical reason: as the city spends billions preparing venues from SoFi Stadium in Inglewood to the expanded Los Angeles Convention Center on South Figueroa Street, engineers and planners pulling site photographs from city servers have repeatedly encountered conflicting or redundant files that slow down approvals. A duplicate image of a retaining wall or a utility corridor — filed twice under slightly different metadata — can stall a structural review by days. In a project timeline measured in months, that adds up.

How L.A. Compares to London and Tokyo

London's equivalent effort, run through the Greater London Authority's digital services directorate beginning in 2023, focused heavily on planning and land registry image records. The GLA used automated deduplication software to flag files before human reviewers made final deletion calls — a two-stage model that city technology officers there credited with reducing redundant storage by a significant margin across borough-level planning systems. Tokyo, preparing its own post-Olympics infrastructure review after the 2021 Games, took a more centralised approach through the Tokyo Metropolitan Government's Digital Services Bureau, building a unified asset registry that prevented new duplicates from entering the system rather than retroactively clearing old ones.

Los Angeles has landed somewhere between those two models. The city's Information Technology Agency, which oversees the project in coordination with the Department of City Planning on North Spring Street, opted for a hybrid: automated flagging using a commercial deduplication platform, followed by departmental review teams who make the final calls on deletion or archival. The model reflects a city with decentralised department structures — 44 city departments each with some level of independent data governance — that makes a Tokyo-style top-down registry harder to impose quickly.

The Bureau of Engineering, which manages image records tied to capital projects across all 15 council districts, reported internally that duplicate files had consumed an estimated 18 terabytes of redundant server space as of a January 2026 internal audit. The Information Technology Agency has not released the full audit publicly, and those figures come from a summary presented to the city's ad hoc Committee on Technology and Innovation earlier this year. The project's current contract with the deduplication vendor runs through March 2027, with an option to extend.

What the Olympic Deadline Changes

The 2028 Games deadline is the sharpest forcing function. The Los Angeles 2028 organizing committee, known as LA28, has its own image asset library for venue branding and construction documentation, but it interfaces with city systems at several points — particularly for publicly owned infrastructure like the Sepulveda Basin Recreation Area, which is being considered for equestrian and shooting events. Duplicate or mislabeled photographs in shared databases create version-control problems that both city engineers and LA28 project managers have flagged in coordination meetings.

For residents and businesses, the practical effect is most visible in the permit process. The Department of Building and Safety, which processes tens of thousands of permit applications per year across neighborhoods from Boyle Heights to Canoga Park, has piloted a cleaner image submission portal since February 2026 that rejects files already existing in its database — a front-end prevention measure that complements the back-end cleanup effort already underway.

City officials have not set a firm public completion date for the full deduplication project, but the internal target remains the end of the first quarter of 2027, before the final wave of Olympic venue construction reviews begins. Departments that have not completed their own file reviews by December 2026 face being folded into a centrally managed audit — the kind of administrative consequence that tends to accelerate bureaucratic timelines considerably.
