> ADA does add to the costs of projects
Not in the long run.
ADA just forces better designs. Retrofits are costly.

Committees, political turf wars, getting funding for the project through grants (that are complicated to apply for, that's why you need a dedicated bureaucrat to do it!). Then there's union rules since construction workers from the city are government employees.
That's half a million in employee's salaries right there and not a single concrete steps has been taken yet!
