Methodology
The homepage at https://www.costamesaca.gov/ was loaded in a real headless browser on August 1, 2026 and audited with axe-core 4.12.1, restricted to the WCAG 2.0/2.1 Level A and AA rule tags — the standard the DOJ rule references. Counts are failing elements at each impact level, on the homepage only. Automated checks find a subset of WCAG 2.1 AA; a full assessment also requires manual review. The grade formula and the full open dataset are on the Index page.
