LA's City Archives Struggle With Millions in Duplicate Digital Photos

Los Angeles city departments collectively store an estimated tens of millions of digital image files across fragmented server systems, and a growing share of that data is redundant—the same photograph saved two, three, or more times under different file names. The City of Los Angeles Information Technology Agency has been working through a mandate, formalized in a 2024 departmental memo, to audit and purge duplicate imagery from shared municipal drives before the 2028 Olympic infrastructure buildout generates a second, far larger wave of documentation files.

The timing matters because the city is already under pressure. Every gigabyte of redundant data stored on enterprise servers carries a real cost—cloud storage contracts the city holds with vendors run roughly $0.023 per gigabyte per month at commercial rates, and municipal contracts negotiated through the ITA typically reflect tiered pricing in that range. When you multiply that across petabyte-scale municipal storage, the arithmetic gets uncomfortable fast.

What the Numbers Actually Show

The Department of Public Works, which manages documentation for road projects from the 405 corridor to the Sixth Street Viaduct precinct near the Arts District, was among the first departments flagged in the 2024 audit cycle. Internal file inventories—records obtained through routine budget review processes—showed that duplicate image files in some project folders accounted for as much as 30 percent of total stored assets, according to figures presented at a Los Angeles City Council Budget and Finance Committee session earlier this year. The Harbor Department, operating out of the Port of Los Angeles in San Pedro, faced a similar finding during a separate IT review tied to its capital improvement documentation for the West Basin Container Terminal expansion.

The Los Angeles County Metropolitan Transportation Authority, though a separate agency from the city, has dealt with an overlapping problem as it documents construction progress on the Crenshaw/LAX Line extension and the planned East San Fernando Valley Transit Corridor. Metro's digital asset library, maintained partly through a vendor contract, ballooned significantly during COVID-era remote-documentation practices when field inspectors began uploading raw camera rolls rather than curated image sets. The result: thousands of near-identical site photographs consuming server capacity that now requires active deduplication software to untangle.

The deduplication tools themselves carry costs. Licenses for enterprise-grade duplicate-image-removal platforms used by large municipal clients range from roughly $8,000 to upward of $50,000 annually, depending on the scale of the deployment and whether AI-assisted perceptual hashing—software that identifies visually similar images even when file metadata differs—is included. The Los Angeles ITA began piloting one such platform in the third quarter of 2025 at the El Pueblo de Los Angeles Historical Monument's digitization center near Olvera Street, where archivists have been scanning historical photography collections for public access.

Why This Matters Beyond IT Housekeeping

The practical stakes extend well past server bills. Karen Bass's housing emergency declaration, now in its third year, has generated an enormous volume of photographic documentation—inspection photos, encampment clearance records, Inside Safe program site imagery—spread across the Housing Department, the Los Angeles Homeless Services Authority, and the Los Angeles Police Department. Each agency stores its own copies. Duplicates across those systems complicate legal discovery, slow public records responses under the California Public Records Act, and make genuine audit trails harder to reconstruct.

The city's 2028 Olympic and Paralympic Games preparation is already compounding the problem. The Los Angeles 2028 organizing committee and city agencies are jointly documenting venue construction at sites including SoFi Stadium in Inglewood, the Intuit Dome, and the Los Angeles Memorial Coliseum. Without a standardized image-management protocol established before that documentation wave hits, city IT officials have warned in budget hearings that storage costs and administrative overhead will scale sharply.

For residents and journalists filing public records requests, the practical advice is straightforward: expect slower turnaround times on image-heavy requests through at least mid-2027, while the ITA completes its deduplication audit across the 42 city departments covered under the current contract. The audit's Phase Two—covering the Bureau of Engineering and the Department of Recreation and Parks—is scheduled to begin in September 2026. The city has set a target of reducing redundant digital asset storage by 25 percent before the end of fiscal year 2026-27.
