The Ann Arbor DDA's amended Development and TIF Plan for 2026–2055 took effect April 30, 2026, following City Council approval, with a boundary now encompassing more than 80 city blocks. Read against Plat Street's earlier coverage, the sequence is the story: Washtenaw County used Michigan PA 57 of 2018 to opt its levy out of Ann Arbor DDA TIF capture on a 7–0 vote, the first use of that mechanism against a well-run district (Issues 2 and 3), and the DDA has now locked in a thirty-year plan with an expanded footprint. A district facing a jurisdictional opt-out has two available responses: negotiate the opting jurisdiction back in, or extend and expand the plan so the remaining capture base carries the program. Ann Arbor chose the second. Every Michigan DDA with a TIF plan approaching amendment now has both precedents in front of it.

Watch: Whether any other Washtenaw taxing jurisdiction files an opt-out against the amended plan, and whether the expanded boundary changes the county's calculus.
