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.
In the 1950s, Detroit planning seemed to be all about expressways. This map from the 1951 Master Plan shows the Edsel Ford (I-94) partially built and the Lodge (M-10) creeping Northwest with dotted lines planning to build many more expressways.
The Master Plan also notes that there was a large park within 20min drive or bus ride for every resident of the city.
Come find us this morning at the Gem Theatre for the Civic Tech Forum.
We’ll be talking about people, maps, planners, and how civic tech can bring them all together.
According to the 1915 “Report on Detroit Street Railway Traffic and Proposed Subway” (Barclay, Parsons & Klapp), the Woodward lines saw significantly increased utilization between 1904 (12,990,027 passengers) and 1914 (47,457,294 passengers).
Downtown, where all the routes terminated, impeded efficient movement of people in and out of the city. Therefore, their report proposed a series of rerouting of lines as well as a Woodward Avenue subway system.
This gem of a video (from sometime in 1960s?) that I wish I had known about years before now has been circulating on social media, but needs to be shared more widely.
Former Chair of the Geography Department at Wayne State University, Robert J. Goodman (d.2005), and Gordon W. Draper created this important look at the history behind Detroit’s street patterns.
“To an overhead observer the street pattern of Detroit presents a strange mosaic of conflicting systems which seem to start and end with no apparent reason and to have no relation with each other.”
Who knew that Gratiot jumps one block north before Brush St. so as not to cut through Elijah Brush’s orchard? Or that Detroiters donated 90% of the land in order to create Grand Boulevard? Did you know the Streets in Highland Park are narrower because that city is much older than the areas of Detroit that grew around it? Even Palmer Woods and Sherwood Forest neighborhoods were labeled as “exclusive” at the time with their curved street patterns.
It is all to easy to forget the deep history of Detroit from the original Indian trails that inspired the spoke streets to the varied roads patterns planned at different points in the city’s history. Don’t forget you can use your hand as a map of Detroit if you ever get turned around.
Terrapattern recently launched to investigate typologies of similar places across cities via satellite imagery.
“…the Terrapattern prototype is intended to demonstrate a workflow by which users—such as journalists, citizen scientists, humanitarian agencies, social justice activists, archaeologists, urban planners, and other researchers—can easily search for visually consistent “patterns of interest”. We are particularly keen to help people identify, characterize and track indicators which have not been detected or measured previously, and which have sociological, humanitarian, scientific, or cultural significance.”
I decided to click on the baseball diamond at Tigers Stadium to see what places were similar in “Detroit” – Terrapattern’s sample area for Detroit includes a broader area beyond the city limits, but also cuts off the Far Westside.
The result is this great geographic plot of similar images and a series of snapshots of other baseball diamonds. Terrapattern even gives you a nice GeoJSON file to play with if you want to export your search results. Obviously, this isn’t all baseball diamonds in the city, especially ones that might be overgrown or covered in grass.
The resulting sample area shows the Far Westside cutoff. However, taking into account the significant clustering (z-score: -9.4) in both the suburbs to the east and Downriver, there appears to be a greater level of access to baseball diamonds and/or maintained baseball diamonds.
The unprecedented level of collaboration the Regional Master Transit Plan for Southeast Michigan has produced a hopeful future for a connected region. With over 60% of Detroiters working outside the city limits and over 70% of Detroit jobs held by non-Detroiters, this plan has big potential to improve access to opportunity and equity in our metro-Detroit region.
The map is pretty nice too!
Poverty is a regular topic in Detroit, but there is much more to the data and narrative than an elevated rate of poverty. Since 2000, the Detroit metro area has seen some of the largest increases in racially concentrated poverty (see 2000 map below for comparison).
These maps are part of the Liquid Planning Detroit report from the Detroit Sustainability Indicators Project that sought to reimagine urban infrastructure in Detroit as population is not expected to grow significantly for some time.
“. . .the redrawing of territorial boundaries within the city of Detroit thereby shifting from an infrastructural logic to water-driven one (from sewersheds to watersheds).”
Back in 2009, Rob Linn dug through City of Detroit Assessor data to look at private land ownership specifically looking at some of the city’s largest private land holders. Michael Kelly and Matthew Tatarian had nearly 1,500 properties in 2009.
“Investors such as Allen Shiffman, Matty Moroun, Michael Kelly and Matthew Tatarian often buy property from the city and county at steep discounts with hopes to resell the properties to other parties – including, ironically, the city and county – at a huge profit. The business models of each speculator range drastically, however, so it is difficult to predict their behavior at auctions.”
The Property Praxis project has found similar high numbers of property under Michael Kelly and Matthew Tatarian’s names in the 2015 City of Detroit Assessor data.
Land in Detroit has been widely covered in the media as the city and it’s residents have grappled with widespread subprime mortgage lending, myriad tax foreclosures, and targeted blight removal.
The primary connection between these major crises and efforts in Detroit is property speculation.
At least 20% of land in Detroit is owned by property speculators, defined by the amount of property they own that is not registered to an owner that lives in the same neighborhood. Property speculators benefited from the new inventory of property created by the mortgage crisis, but in turn fueled the decline into blight of once intact neighborhoods.
This collaborative mapping project is not the first to examine individuals and corporations that have held large swaths of land in Detroit, but it is the first to examine the true extent of property speculation by digging into the records of shell companies and LLC that are often used to hide ownership or skirt tax payments. Not all property speculators are bad people, but the process of speculation has far reaching negative impacts on neighborhoods and the people who live in them.

From the New York Public Library (NYPL) digital collections, this map from 1939 shows all the main roads and their status as paved or dirt. Main roads are highlighted in brilliant green.
However, there is no indication of streetcars or any alternative transportation options other than roadways, which seems odd since Rand McNally began by printing timetables for the railroad industry. I guess initiating the numbered highway system and shifting business to publish road atlases for Gulf Oil in the 1920s shifted their focus to roads over rails.
This is the project map from “PIONEERS,” which was commissioned for the “Shrinking Cities” exhibit cohosted by MOCAD and Cranbrook Art Museum in 2002-2008. The PIONEERS project consisted of 12 mini-programs broadcasting on 107.9FM as a way to lift the voices of Detroiters’ to tell the stories of their histories, goals, neighborhoods, communities, and city.

It’s always nice to see Detroit as the focal point for national or regional maps.
“Detroit’s proximity to the geographical center of the nation’s population is obvious.”
This map comes from the 1949 master plan for the “Detroit Festival of the Great Lakes” to be held in 1951 at the 250th anniversary of Detroit’s founding. The Michigan State Fair Grounds were the chosen spot because of easy access via U.S. 10 (Woodward Ave.) and Michigan 102 (Eight Mile) as well as U.S. 16 (Grand River) and U.S. 112 (Michigan Ave.). The new Grand Trunk Railroad passenger platform at the Fair Ground was also projected to be used.
It was written that:
“The Michigan State Fair Grounds is conveniently located for both the farm families and the city families of Michigan. It is central to the heavily populated southeastern part of Michigan. 3.5 million people live within 50 miles of the grounds, almost 3/5 of the residents of Michigan, plus 150,000 in the neighboring Canadian province of Ontario.”
Major changes have been taking place in the Cass Corridor and those changes have accelerated in recent years. Concerns were raised by nonprofits in the early 2000s with the creation of “Midtown” and those same concerns are being raised as the new Red Wings arena is being constructed and property values skyrocket.
This map is a representation of the pathways of the often invisible people in the Cass Corridor. Detroit’s Neighborhood Services Organization (NSO) provides programming and resources to the city’s vulnerable neighbors, many of whom are located in the Cass Corridor area. Desire lines or desire paths are the wore trails that people create between places and spaces when there isn’t necessarily a planned route. The mobility of the vulnerable people in the Cass Corridor is visible here as the desire lines have a clear radial pattern around the NSO building.
