San Antonio's Digital Archives Hold Thousands of Duplicate Images — and the Cleanup Numbers Are Staggering

San Antonio's city government is sitting on a digital storage problem it has spent the better part of three years trying to fix. An internal audit of the city's public-facing web infrastructure, conducted through the Office of Innovation and Technology on Dolorosa Street, found that duplicate and low-quality images account for a significant share of file bloat across at least fourteen municipal department portals — slowing load times, complicating public records requests, and drawing scrutiny from city council members who oversee the IT budget.

The issue matters now for a practical reason: San Antonio is mid-way through a $4.2 million digital modernization contract awarded in fiscal year 2025, and duplicate image replacement has emerged as one of the more labor-intensive line items. With the city's population crossing 1.5 million and municipal web traffic climbing sharply since the pandemic, the administrative overhead of managing redundant files is no longer a back-office inconvenience — it directly affects how fast residents can access permit applications, zoning maps, and public health resources.

What the Numbers Actually Show

The audit, which covered the period from January 2023 through March 2026, flagged more than 38,000 image files stored across city servers as probable duplicates — meaning identical or near-identical files saved under different filenames or in different folder structures. Of those, roughly 14,200 were tied to the Development Services Department, which manages building permits and land-use documents for neighborhoods from Lavaca to Stone Oak. The Planning Department's GIS portal accounted for another 6,800 flagged files, many of them outdated aerial photographs that had been re-uploaded without archiving the originals.

Storage costs tell part of the story. Cloud and on-premises storage for city departments runs on a tiered pricing model; redundant image files that are never purged continue to consume storage allocation that costs the city roughly $0.023 per gigabyte per month under its current vendor agreement. Multiply that across tens of thousands of files and the bill adds up faster than most residents would expect. The San Antonio River Authority and VIA Metropolitan Transit, both of which share certain data infrastructure agreements with the city, have separately undertaken their own deduplication reviews this calendar year.

The replacement process itself is not simply a matter of deleting extras. Each flagged image must be reviewed to confirm it is not the only surviving copy of a document, a process the city's digital records team estimates takes between four and seven minutes per file. At that rate, clearing the full backlog of 38,000 flagged images would require somewhere between 2,500 and 4,400 staff hours — a figure that explains why the project is being phased across three fiscal years rather than handled in a single push.

Where the Work Is Happening

The most visible progress has come at the San Antonio Public Library system, which manages its own image repository separate from city hall. The Central Library on Soledad Street completed a deduplication pass of its digital collections in February 2026, reducing its image file count by 22 percent and freeing up storage that staff redirected toward digitizing physical photograph collections held in the Texana/Genealogy department on the building's sixth floor.

The Development Services Department, headquartered on Dwyer Avenue, is targeting completion of its duplicate-image audit by the end of the third quarter of fiscal year 2026 — which runs through September 30. Staff there have piloted automated hash-matching software since October 2025 to accelerate the review process, a tool that city IT officials say reduced manual review time on a test batch of 500 files by roughly 60 percent.

For residents who use city portals regularly — whether to track a permit on the MySA platform or pull zoning records for a property near the Pearl district — the practical payoff from a completed cleanup would be faster page loads and fewer broken image links on documents older than 2019. The city's IT office has published a project status page on sanantonio.gov where residents can track quarterly milestones. The next update is scheduled for August 1, 2026.
