After a meeting that dragged past 1 a.m., Washtenaw County commissioners signed off in a 6-2 vote on a massive brownfield tax-increment financing package for the proposed Arbor South neighborhood on Ann Arbor’s south side. The deal lets developers capture more than $300 million in future property taxes, and it has split local leaders over whether this is a critical tool for housing or a pricey handoff of public dollars to private builders.
The Board of Commissioners’ approval clears a key hurdle for Arbor South, but came over strong objections from Commissioners Yousef Rabhi and Caroline Sanders. Rabhi zeroed in on the developer’s stated 7.4% profit margin, warning that it could mean roughly $26 million in captured tax revenue ending up as private profit. Local attorney Tom Wieder also told reporters the package could face legal challenges if it moved forward, according to MLive.
What the plan would build
City brownfield documents describe a five-phase overhaul of roughly 17–20 acres at State Street and Eisenhower Parkway, swapping out surface parking lots and a gas station for a dense mixed-use district. The concept calls for more than 1,000 housing units, a hotel, ground-floor retail, public plazas, and up to three parking decks.
About 209 of those homes are slated to be income-restricted and owned by the Ann Arbor Housing Commission, according to the City of Ann Arbor brownfield plan. The project team lists Ann Arbor-based Oxford Companies and Dublin, Ohio-based Crawford Hoying on the development website Arbor South.
How the tax capture breaks down
The brownfield plan outlines more than $329 million in tax revenue that could be captured over 30 years. County records indicate that once state and local brownfield fees are included, the total could reach about $374 million.
Coverage of the vote details a projected split that would direct roughly $135 million to Ann Arbor public schools and state education taxes, $81 million to city taxes, and $39 million to county taxes. Millions more are expected to go to the Washtenaw Intermediate School District, Washtenaw Community College, the Ann Arbor District Library, and local transit systems. The plan also allows up to $345 million in reimbursements for eligible development costs if revenues outperform projections, according to MLive.
Supporters' case and critics' concerns
Supporters argued that the tax capture is essentially self-funded, since the new tax revenue would exist only after the buildings are constructed. In their view, the district is designed to pay its own way while covering big-ticket items like parking decks and environmental cleanup.
Backers also highlighted the project’s affordable housing commitments and the long life span of public infrastructure that would be built with captured taxes, which they say will remain in place well beyond the 30-year capture period. Coverage from WEMU and city staff reports indicates that a large share of the funding is earmarked for parking structures and sewer work. Opponents counter that the same dollars should instead bolster budgets for schools and colleges.
Process and next steps
County approval is only one step in a longer process. The brownfield framework still requires a reimbursement agreement, possible city bond issuances to purchase parking decks, and additional state-level filings tied to brownfield and environmental work, according to the City of Ann Arbor.
City documents state that Priority One reimbursements will focus on parking structures, with Priority Two aimed at other on- and off-site infrastructure. Staff have argued that this structure is meant to keep public benefits coming online alongside private construction.
Politically, the vote has already sparked broader debate over tax policy and the upcoming mayor’s race. Critics say they will continue to pressure both the county and the developers, while legal observers are watching for any formal challenges. The 6-2 vote cleared a major hurdle for Arbor South, but detailed financing agreements and the first site plans still need to be hammered out before any cranes rise over State and Eisenhower.
