Map: Detroit Toxic Chemical Releases 2024

This map displays data from the Toxic Release Inventory (TRI) Program at the EPA, which has been under attack in recent years so I'm hoping the data is still reliable and maintained. The majority of toxic releases in Detroit came from the EQ Detroit (better known as US Ecology) facility near the former incinerator location and from the Stellantis Plant on the city's Eastside.

Map: GLWA Stormwater Control in Metro Detroit

The University of Michigan Urban Collaboratory worked with the Great Lakes Water Authority (GLWA) in 2018 to better handle combined sewer overflows in real-time. More from the project: ... they found that Combined Sewer Overflows have been occurring when additional sewer capacity is available. Rather than increasing the amount of storage with costly infrastructure improvements, the research team was able to demonstrate their ability to use a real-time control approach to significantly improve the existing GLWA wastewater and CSO management system by reducing both the occurrence of CSOs and peak flows going to the treatment facility.

Map: The Original Midtown Community 1953

This historic gem of a map comes from the Reuther Library and Archives, "Community Councils Manual, Dec. 1953" (page 5) published by the Detroit Federation of Community Councils. I've been diving into neighborhood histories and came across mentions of a "Midtown Community Council" in the 1950s and had to dig in further.

Map: Detroit Food Pantry Finder 2025

The City of Detroit has taken small steps to better engage with the food system in moments of crisis. The first was food box distribution during COVID-19 and now they have a team verifying food pantries in the midst of uncertainty with federal nutrition benefits. This kind of verification is critical to make sure people can find the right resources and I truly hope this is connected to the wider safety net efforts of the United Way's community information exchange.

Detroit Recreation Property Map 1976

I can't remember where I found this map, but I'm glad that I did. The map is huge and could only be scanned using the large format, flat-bed scanner at the Reuther Library.

I used an early GIS program to load the GPX files and created the finished product by hand.
