Several follow-up items revisit the troubled contaminated-soil work under Prop N — including whether to waive privilege on a Law Department memo about site-by-site accounting. Residents near remediation sites are watching for accountability.

MeetingNov 2, 2026

Public Health and Safety Standing Committee

The Law Department submitted a privileged memo on site-by-site accounting of contaminated-dirt removal sites. The committee directed drafting of a resolution to waive privilege so the full council can make it public, with a one-week return. McCampbell's related Prop N remediation memo also returns in one week.

MeetingOct 30, 2026

Committee of the Whole

A contractor (Gyanga) and a fill source (Iron Horse) supplied unapproved, contaminated dirt to city demolition sites — 655 in total. 500 of 533 tested public sites failed state residential cleanup standards, and about 195 pose elevated health risks from direct contact or vapor intrusion. Cleanup so far cost $7.8 million with $11.65 million more needed.

Detroiters likely to bear the cost of ‘dirty dirt’ site remediation, city’s top lawyer says

Detroit’s top attorney said Friday that the contractor responsible for the “dirty dirt” is unlikely to have the resources to cover the costs and, absent state or federal grants, the bill for remediation will most likely fall on Detroiters.

Detroit could block billionaire-owned concrete plant from further neighborhood expansion

We reported on how a concrete plant took over a Detroit neighborhood after a historic land swap facilitated by city officials. Now after years of complaints from residents about dust and noise, officials say they want to limit further growth.

Public Health and Safety Standing Committee

Residents and council members raised serious concerns about contaminated fill dirt used across Detroit demolition sites, demanding a complete site-by-site accounting and clearer remediation plans.

MeetingOct 5, 2026

Public Health and Safety Standing Committee

Council wants a full site-by-site accounting of every property that received contaminated or potentially contaminated fill dirt, and a follow-up on funding.

MeetingOct 1, 2026approved

Neighborhood and Community Services Standing Committee

The city is running low on environmental testing capacity for its lead hazard remediation program because two of four contractors left. Two CDBG-funded contract increases keep lead, water, soil and air inspections going while new firms are procured.

MeetingSep 28, 2026

Public Health and Safety Standing Committee

Members again delayed demolition contracts while demanding a site-by-site accounting of where contaminated dirt went and how much cleanup will cost. Waters and Santiago-Romero warned the city is paying for demolitions already done — without approval — and may be repeating the contamination problem with the same contractors.

MeetingSep 21, 2026

Public Health and Safety Standing Committee

Council Member McCampbell is still pressing for a complete site-by-site list of every property that received contaminated or potentially contaminated fill dirt. A caller cited estimates of 650 sites needing redo work at roughly $30,000 each — about $25 million.

Public Health and Safety Standing Committee

MeetingMay 11, 2026

Public Health and Safety Standing Committee

The city is still cleaning up contaminated fill left at demolished properties, and it's expensive — one site costs $51,842 to remediate.
