Left in the dust: How a billionaire-owned concrete plant took over a Detroit community

July 6, 2026

Crown Enterprises, a real estate firm owned by Detroit's wealthy Moroun family, has systematically acquired over 160 properties in the Cadillac Heights neighborhood through a 2019 city land-swap deal and subsequent purchases, transforming the residential area by demolishing homes and operating a concrete-mixing plant called Kronos. The plant has generated persistent dust pollution, noise, and industrial disruption, prompting approximately 80 complaints from residents, though city and state officials have rarely enforced violations due to a unique property maintenance agreement that allows Crown to avoid fines. The original land swap, championed by former Mayor Mike Duggan to facilitate a Stellantis auto plant elsewhere in Detroit, gave Crown first rights to purchase additional neighborhood properties through 2034, effectively enabling the company's takeover.

Who is affected

Christina Kary (86-year-old longtime resident whose family built the first houses in Cadillac Heights in the early 1900s)
Remaining residents of Cadillac Heights neighborhood, particularly those living near the Kronos concrete plant
Matthew Tomasz (former resident who sued Crown and eventually sold his home to the company)
Mitchell Gross (50+ year resident whose son and grandchildren left Detroit due to health concerns)
Samantha Flowers (resident who sold her home and parcels to Crown)
Jahdante Smith (Detroit resident who filed dust complaints)
At least 16 residents who have sold their properties to Crown since the land swap
Workers employed at the Kronos plant (described as Detroit hires by the company)
Community groups receiving donations from Crown
Broader Detroit residential neighborhoods hosting other concrete facilities

What action is being taken

Crown Enterprises is operating the Kronos concrete plant six days per week
Crown is purchasing additional properties from homeowners to create a buffer around the plant
Crown is spraying water every hour the plant operates to minimize dust
Residents are filing complaints with city and state environmental offices (about 80 complaints filed since the plant opened)
Residents and advocates are protesting, speaking at City Council meetings, and collecting signatures to shut down the plant
The Wayne County Commission is paying JustAir to track and analyze air quality near Kronos
Mayor Mary Sheffield's administration has installed four air quality monitors near the plant
City inspectors are issuing tickets to Crown for violations (though most are being dismissed under the property maintenance agreement)
Councilmember Scott Benson is advocating for zoning changes to make the area less industrial

Why it matters

This situation represents a fundamental tension in Detroit's post-bankruptcy rebuilding between economic development and residential community preservation. The case demonstrates how municipal decisions prioritizing infrastructure development and job creation can systematically dismantle established neighborhoods, particularly when special agreements shield companies from enforcement. It reveals problematic governance practices, including a unique property maintenance agreement that effectively exempts Crown from fines, permits issued despite outstanding violations, and a land swap deal that gave one company unprecedented control over neighborhood property acquisition for 15 years. The story illustrates environmental justice concerns, as working-class Black residents bear the burden of industrial pollution while witnessing their century-old community disappear. It also raises questions about municipal accountability when officials admit they would have asked "additional protections and questions" had they known the consequences, yet legal mechanisms to reverse course appear unavailable even as residents suffer documented health and quality-of-life impacts.

What's next

Crown plans to demolish additional homes it has purchased, including one acquired in January (waiting for utilities to be disconnected)
The city is considering rezoning some parts of Cadillac Heights to make them less industrial, though plans currently stop short of Crown-owned lots
The Moroun family's concrete supply business, Hercules Material Holdings, expects to open additional facilities in Toledo, Ohio, and Windsor, Ontario
Mitchell Gross said he will plant evergreen trees himself to filter dust if Crown doesn't make improvements soon
Crown retains first rights to purchase additional properties in Cadillac Heights through 2034 if they enter the Land Bank
The city will not grant Crown permission for neighborhood improvements until the company addresses code violations, including an unpermitted fence and inadequate operational screening
