Dearborn trustees hear $1.5 billion facilities estimate, weigh preservation vs. new construction

Trustees of the Dearborn City School District heard consultants present options for a long-range facilities program and debated how much of the district’s aging inventory should be preserved rather than replaced.

A consultant said a 30-year model based on recent local examples produced an illustrative figure near $1.5 billion and warned that inflation and supply-chain pressures mean later projects will likely cost more. Trustees compared that modeled figure to an Ann Arbor program cited by one member as a $2,000,000,000 benchmark.

The discussion centered on how the district will define "historic" and how preservation would affect feasibility and cost. Consultants said buildings generally become candidates for historic review once they are at least 50 years old, and that historical value, structural integrity and neighborhood context must be assessed on a case-by-case basis. A presenter said the project team includes historians and that some older schools can be adapted successfully because of durable construction and higher floor-to-ceiling heights.

Trustees repeatedly pressed for building-level cost comparisons and asked consultants to show options that include major renovation, adaptive reuse and new construction for each school. Presenters said the current analysis will provide three options (renovation, major renovation and new construction) with associated costs and escalation assumptions so trustees can evaluate trade-offs for each site.

Consultants also addressed operational and sustainability implications. One presenter said energy-efficiency upgrades and mechanical-system replacements are part of the baseline recommendations and can reduce long-run operating costs and embodied carbon compared with poorly maintained older systems.

On phasing and affordability, consultants described strategies used elsewhere: staging work in phases, reusing boilers and window air-conditioning units as short-term stock, and limiting large construction volumes to $100 million–$300 million per year to match labor availability and summer-only construction windows. They warned that labor and materials costs have risen — roughly 30 percent since the pandemic, by the consultant’s estimate — and that tariffs and global supply disruptions make exact escalation rates unpredictable.

The consultants outlined a community engagement program that will include one-on-one stakeholder interviews, focus groups and a districtwide survey; they said they expect to finalize the draft report in early June and recommended taking time to educate voters before selecting a ballot date.

Trustees did not set a bond amount at the meeting. Several members emphasized they want a transparent, building-by-building presentation to the public that includes preservation options as well as replacement scenarios before the board decides whether and when to place a bond question before voters.
