This map demonstrates the electrical system in Detroit as of 1915 projected to 1924. The interconnected dual generating plant system in the city supplied over 300 miles of electrical cable across the city. However, by 1922 the Detroit system was becoming strained for capacity. As the surrounding region continued to grow the Detroit system became overtaxed and additional plants had to be constructed in Monroe and Marysville to bear the load of the electricity demand.
In a major advancement in Detroit public transportation, DDOT announced that it will expand 24-hour service to a number of routes.
Since the major reductions in DDOT services in 2012, this is an incredible and welcome change. The increased mobility and services will hopefully improve the day-to-day experiences for many Detroiters.
In 1940, the Department of Parks and Boulevards was merged with the Department of Recreation to aid “economy and efficiency.” The new Department inherited 4,162 acres of land in 138 locations:
In 1946, the new Department added an additional 1,005 acres with plans for an additional 269 acres at 41 sites to bring the grand total by 1950 to 5,521 acres.
This map serves as the cover art for a report titled: “some notes on the Detroit negro vote.” The map notes that the Fifth Ward and area best known historically as Paradise Valley has been a majority African American area. The report goes on the chart the Black vote in Detroit and its precipitous decline in support of Republican politicians between 1932 – 1952. It notes that in 1932 the majority of the Black vote went to Hoover over Roosevelt.
Amid the firestorm that was/is Pokemon Go, an interesting geographic disparity was discovered. The above map has been shared widely and articles have covered why majority Black cities have fewer pokestops. The map displays “claimed” pokestops and not all pokestops, but regardless demonstrates serious disparities.
The problem is that pokestops relied on a database of historic markers and crowdsourcing. Locations were crowdsourced from Ingress, a previously established real-world/virtual reality game. The most important point being here that the crowdsourcing is only as good as the crowd. For Detroit that means a heavy density in Downtown, Midtown, and along the Woodward Corridor, but not as much in the neighborhoods.
Internet access disparities, smartphone reliability, service coverage, opportunity and income gaps – sometimes it is the little things that demonstrate the most persistent problems we face.

The Detroit Greenways initiative has been working hard to develop an “inner circle” greenway to allow non-motorized transit around the entire city. Little did we know that this was similarly proposed Around Outer Drive in the 1915 Preliminary Plan of Detroit by Herbert Bennett.
Artesian, not to be confused with the wave “artisanal” foods and other products these days, refers to the geology of accessing underground water sources. From USGS:
Groundwater in aquifers between layers of poorly permeable rock, such as clay or shale, may be confined under pressure. If such a confined aquifer is tapped by a well, water will rise above the top of the aquifer and may even flow from the well onto the land surface. Water confined in this way is said to be under artesian pressure, and the aquifer is called an artesian aquifer. The word artesian comes from the town of Artois in France, the old Roman city of Artesium, where the best known flowing artesian wells were drilled in the Middle Ages. The level to which water will rise in tightly cased wells in artesian aquifers is called the potentiometric surface.
This map is included in the 1917 “Detroit folio, Wayne, Detroit, Grosse Pointe, Romulus, and Wyandotte quadrangles, Michigan” with geological analysis by W. H. Sherzer. It is interesting to see that Springwells was historically an area where flowing wells were “known to occur.”
At the August 4th, 2016 Community-wide meeting, Mayor Duggan and new Planning Director, Maurice Cox shared information about how the city will be planned for the future and specifics on the goal of creating “20 minute neighborhoods.”
As part of tackling the size and expansiveness of Detroit, the Planning and Development Department (PDD) is breaking the city up into East, West, and Central “Design” Districts – not to be confused with the “Design District” proposed for Cass Corridor or the existing City Council Districts.

This map by Dr. Steven Fleming of Cyclespace looks at space for bicycles in Detroit with a dense and bikeable future:
Did you know that a 9.3 mile (15 kilometer) diameter city, if it were as dense as Manhattan, would have a population of 6 million people? And did you know that if it were designed around cycling – the way, say, Houston was designed around driving, or how Venice was designed around boats – and if no vehicle were allowed in that city that impeded the smooth flow of bikes, that the average commute time would be faster than in any other city that size? This was one finding from a design research project I ran. I’m now in the process of disseminating these and other findings to my colleagues and bike transportation enthusiasts.

WDET’s CuriosiD series recently examined the idea of the “Gayborhood” in Detroit. Many people assume that the northern suburb of Ferndale hosts the most gay-friendly establishments, but just south of 8 Mile there existed and still exists a strong gay neighborhood in Detroit’s Palmer Park area. The main difference today is the demographic shift.
“I think it would be a mistake to say that Palmer Park is no longer a gay neighborhood,” says Dr. Tim Retzloff, a historian who has tracked the gay migration in Metro Detroit. “In some respects there’s still a strong gay presence in Palmer Park, it’s now just an African-American gay presence and not a White gay presence.”
Listen to the whole story on WDET.
This map represents an analysis from the 1915 “Report on Detroit Street Railway Traffic and Proposed Subway” (Barclay, Parsons & Klapp) looking at travel times from Downtown. The isochrone lines show that in 1915 it would take 40min to get 7 miles (to Highland Park) and the same distance and time to reach Grosse Pointe Park.
The Design Inquiry (DI) group made up of Dan McCafferty, Joshua Singer, Patricio Davila, and Rachele Riley created this installation at MOCAD based on some of our data and others:
The Different Data Detroit project is a mapping of various narratives of the city of Detroit, combining and layering data gathered from diverse sources: information on water usage and future water infrastructure (from Detroit Future City proposal and Detroitography); visualizations and reports on spaces in Detroit whose official use is ‘unknown’ (as determined by Data Driven Detroit in their recent Motor City Mapping Parcel Survey); historical maps, large sample collections of typographic typologies from the urban landscape; our own photography, notes, and GIS mappings from field visits in the city; imaginary structures that delineate hidden pasts.
Yesterday’s #Maptime workshop went analog at Repair the World (which has their own awesome wall map). This time we were focused on the time-tested practice of hand drawing maps. Each person took a different section of Southwest Detroit to recreate in their own style.
Using fieldpapers.org, I generated a quick grid for Detroit that wasn’t too granular, but allowed for a single page to have a good amount of detail.
Everyone has a different way of viewing and understanding maps and geographic areas. Since we were focused on Southwest Detroit there were a number of discussions about industry, pollution, and environmental impact.
This map was found and posted by architect, Robert Saxon Jr., while looking for historic information on Detroit brickyards.
It’s unclear whose signature “T. Klug” appears in the bottom corner. Nevertheless, a great example of a hand drawn map used to understand a specific area of Detroit.
UPDATE 07/08/16: Dr. Thomas Klug, Director of the Institute for Detroit Studies at Marygrove College has confirmed he is the map creator. The map was part of a 1999 Report titled: “Railway Cars, Bricks, and Salt: The Industrial History of Southwest Detroit Before Auto.”More from Dr. Klug:
I used a relatively contemporary map of Detroit…in order to situate “industrial” places in SW Detroit based on the 1905 city directory and the 1899 Sanborn maps.
It was a real eye opener to come across all those brick yards in Springwells Township. They looked pretty impressive in the Sanborns, and i came across a description of the miserable conditions facing the workers (German immigrants) from the Michigan Bureau of Industrial & Labor Stats.

Nothing beats a good mental map. Nothing.
It has been great participating in the Data Discotech’s put on by the Detroit Community Technology Project (DCTP). In the last event held at the Boggs School, we shared the hand map example to help students understand the geography of their city.
Hand maps are rarely accurate, but help build a conceptual understand of the world around us. The Boggs students taught us as much about the geography of Detroit as we hoped to teach them about spoke streets.
This map is from La Nouvelle Géographie universelle, la terre et les hommes, 19 vol. (1875-94) by the French cartographer, Charles Perron published with colleague Élisée Reclus. The two cartographers produced nearly 10,000 maps from the 16th to the 20th century, including several reproductions of early maps from Antiquity and the Middle Ages. They were considered pioneers in the field of cartography.
This Washington Post article uses data from Black Knight Financial Services to examine home values pre-recession to the more current 2015 home values. As many other socio-economic analyses have suggested, the examination of home value data shows a deeply uneven recovery. On the data:
“The estimates reflect repeat sales and loan data from 2004 to 2015 across the country, down to the neighborhood level for some 19,000 Zip codes. Values are not adjusted for inflation. The data are adjusted to correct for the sales prices of distressed properties such as foreclosures to better capture what homes would sell for on the open market.”
Across zipcodes in Detroit, home values are down between 50% and 73%. The zipcode 48216, where Corktown is located and quickly becoming an expensive neighborhood in which to own housing, has seen the lowest home value loss since 2004.
Spent the day starring at this colorful wall map of Detroit in Repair the World‘s space in Southwest.
It’s not the most geographically accurate, Belle Isle is a little shaved down on one end, but it sure is beautiful and must have taken a long time to put up. Each block of color looks like it was painted, but I might be wrong.
From the Detroit City Plan Commission’s “Central Business District Study: Land Use, Trafficways, and Transit: A Basis for the Long Range Growth of Downtown Detroit.”
Compared to the most recent data on building heights, not too much has changed. Most notably the Renaissance Center had not yet been built (see the large empty space where Woodward ends at the Detroit River).
Francis Grunow wrote a post a while back on the shortcomings of the Detroit Future City plan, its lack of regionalism, and collaborative pathways that could be used moving forward. Most notably, he calls for a Planning Corps to integrate efforts with existing community-based organizations.
He also drew this map to accompany the post which mashes up City Council Districts and neighborhood names within those areas.
