What WCAG 2.1 Level AA means for city government websites

Because Centennial serves 108,853 residents — above the DOJ's 50,000-person threshold — it falls in the first enforcement wave, with the earlier of the two federal deadlines.

WCAG 2.1 Level AA is the technical standard the DOJ adopted for ADA Title II. In plain terms, it's a checklist that makes sure residents who use screen readers, keyboard navigation, or captions can actually use your website: text on every image, labels on every form field, enough color contrast to read, and video captions.

For first-wave entities, the practical risk isn't only DOJ action — it's private lawsuits and demand letters that cite the federal standard the moment the deadline passes.

Centennial is a major population center, and its website is the front door for business licensing, utility sign-up, and code enforcement requests. Under ADA Title II, that front door has to work for every resident.
