What it runs on
The site served a page identifying CivicPlus. That matters more than it sounds: across the whole survey, failure tracks the platform far more closely than it tracks the size of the government. A defect in a shared template is not something one town can fix alone — and it is not something one town caused.
What was found
- Frames must have an accessible name — 4 instances (serious)
- Zooming and scaling must not be disabled — 1 instance (moderate)
- [role="img"] and [role="image"] elements must have alternative text — 1 instance (serious)
Most of these are fixable without redesigning anything: colour contrast, missing labels, links with no discernible text.
The deadline that applies here
26 April 2028 — entities under 50,000, and all special district governments.
The Interim Final Rule of 20 April 2026 split the ADA Title II compliance date in two. Remediation, document cleanup and vendor contracts routinely run 12 to 18 months.
What this does not show
- Homepage only. One page was tested. This site may pass its homepage and fail everywhere behind it.
- Automated only. Automated testing catches roughly a third of real accessibility problems. It cannot judge whether alt text is meaningful, whether a form works with a screen reader, or whether a keyboard user can escape a menu. Passing every automated check is not compliance.
- This is a floor, not a verdict, and not a legal opinion.
