Flint, the Vehicle City, birthplace of the General Motors Company and the United Auto Workers, a vanishing city propelled to the spotlight by one of the largest municipal public health crises in the 21st Century, the Flint Water Crisis

  • Mapping Flint: Roadways, Boulevards, Avenues, and Streets

    Flint’s roadways follow a merged historical pattern and urban grid layout. The downtown area features a high-density, traditional grid network near the Flint River and surrounding areas like Saginaw Street and Beach Street.

    Much like Detroit, early roadways were defined around the river direction before being planned by cardinal directions. Key north-south routes include Saginaw Street, Chavez Drive, and Crapo Street. Major east-west routes include Third Street, Kearsley Street, and Robert T Longway Boulevard.

    I first saw this roadway name-mapping idea in Bill Rankin’s work in Vancouver, and then Derek Watkins applied a similar approach to the Portland–Seattle area. I was finally given my last push and decided to create this map after following Bostonography — which mapped out the roadway naming in the City of Boston. This type of map has now become a commonly created map of interest for any city. There are tiny details that reveal interesting bits of history and take you down new paths.

    The patterns of roadway naming show the growth and change of Flint over the years. There are not many Boulevards which show how that road type was reserved for important places. The “Road” naming itself didn’t become more common until after U.S. control of the Michigan Territory, when standardized land surveying and urban planning instituted a recognizable grid system.

    It appears that “Street” was the top choice of early Flint development, while “Avenues” became popular later. The Avenue groupings pop up on the edges of the city. Notably, Flint’s hydrology: rivers and creeks heavily influenced the road layout, creating areas of less roadway density.

  • Downtown Flint Walking Maps 2011

    I found these “Flint by Foot” maps by The Greenway Collaborative to be interesting as a point in time image of what Downtown looked like and how opportunities were presented before the Great Recession and before the Flint Water Crisis. Walking across Downtown from Kettering to Mott Park past UM Flint campus was estimated to take 45 minutes.

  • Flint Fictional Metro Transit Map

    What if “Vehicle City” had a metro rail system? This is a long running topic for the Detroit metro area where I organize an annual “transit fantasy” meetup where people have created over a dozen fake mass transit systems over the years.

    This transit fantasy map of Flint comes from Redditor, RikkaTheSecond:

    I was bored and decided to make a Metro Map! I randomised all the cities in the US to decide what to do and it came up with the quaint town of Flint, Michigan, north of Detroit. This was probably the most design-focused map I’ve done in a while, as halfway through making it I really started loathing the design. I did my best to try and make it look good and overall I think I did a good job. Let me know what you think of it!

  • Mapping Flint: Flint River Watersheds

    The Flint River Watershed is a vital, 1,363-square-mile drainage basin across seven southeastern Michigan counties, ultimately feeding into the Saginaw Bay and Lake Huron. Originating in Columbiaville, the river flows northwest through diverse landscapes, including agriculture, forests, and the urban center of Flint.

    Historically central to regional development and mill power, the watershed now faces significant environmental stress from industrialization and urban runoff. Persistent issues such as nutrient runoff, bacterial contamination, and legacy pollutants threaten aquatic life and recreational use, making cleanup essential for the region’s ecological and economic health.

    Numerous organizations are actively dedicated to the conservation and restoration of the Flint River Watershed. Leading the local charge is the Flint River Watershed Coalition (FRWC), a non-profit group that focuses on monitoring water quality, restoring natural habitats, and educating the public. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) provides regulatory oversight, funding, and technical assistance. This multi-faceted, collaborative approach is essential for addressing contamination.

    Larger regional and national organizations, such as the Saginaw Bay Watershed Initiative Network (WIN), support the health of the Flint River by addressing broader ecosystem connections and non-point source pollution. Various environmental groups and universities also contribute by conducting research on pollution sources, developing innovative restoration techniques, and advocating for stronger environmental policies.

    This network of dedicated organizations is crucial to the ongoing work of protecting, restoring, and ensuring the long-term vitality of the Flint River and its surrounding lands.

  • Flint Pipe Map: Mapping Water Service Lines 2022

    The “Flint Pipe Map” was created in October 2020 and last updated in June 2022. The map is based off of a mathematical model that predicts water service line material based on multiple factors like building age, existing water line inspection data, and other factors.

    More from the FAQ:

    This map provides information about the known or likely material of the water service lines at different addresses in Flint, Michigan. It is intended to share up-to-date water service line information with the citizens of Flint. The map includes information gathered by the City of Flint during water line inspections and/or replacements. At residential addresses where the City has not yet inspected the water service lines, the map indicates the likelihood of lead or galvanized steel service lines based on mathematical modeling by Dr. Jacob Abernethy and Dr. Eric Schwartz. The map website was built and is maintained by Jared Webb. Dr. Stacy Woods of the Natural Resources Defense Council collaborated on the map and site design.

    Dr. Jacob Abernethy and Dr. Eric Schwartz and their affiliates do not guarantee the accuracy of the information contained in the Flint Water Service Line Materials Map or otherwise represent that the map is accurate. The Flint Water Service Line Materials Map shall be used for the sole purpose of providing Flint residents with the best available data regarding their water service lines, and not for any commercial, legal, or other use. Dr. Jacob Abernethy and Dr. Eric Schwartz reserve the right to alter, amend, or terminate at any time the display of the Flint Water Service Line Materials Map.

  • Mapping Flint: Vacant Land

    Flint is home to “The” Land Bank, or at least the first modern implementation of a public authority tasked with managing vacant properties. Today there are 353 land banks at the city, county, or state level. Most land banks take advantage of state level laws that enable them to exist and in Michigan that law was passed in 2004. In Michigan, a new interpretation of brownfields, or any property that has been developed, opened the door for innovation in managing vacant and abandoned properties to bring them back to productive use for cities. 

    The Genesee County Land Bank Authority (GCLBA) has tracked its work since 2004 and boasts over 9,000 structures, sales of over 10,000 vacant lots, and 5,000 lots back to community uses. The GCLBA has taken control over over 14,000 properties in its time, but still has an inventory of 13,626 properties. The GCLBA’s property inventory is 80% vacant land. Across the City of Flint there are over 17,000 vacant lots and not all of them are publicly owned or managed by the GCLBA. 

    The distribution of ownership across vacant land in Flint shows how difficult it can be to manage land in a city experiencing economic stress. The majority of GCLBA vacant land is residential while most of the privately held vacant land is commercial and industrial.

  • Map: North Flint defined by Mott Foundation

    What cardinal direction matters most in Flint? The Mott Foundation is focused on North Flint:

    “We define north Flint as everything within the city limits north of the Flushing Road/5th Avenue/Longway Boulevard corridor.”

  • Map: Crapo Island on the Flint Sanborn Map 1886

    Sanborn maps are a useful historical tool and often reveal interesting pieces of the past that are long forgotten. On this fire insurance map in particular I was surprised to see such a sizable island in the Flint River, Crapo Island.

    Named for Henry Crapo, the UM Flint Genesee Historical Collections Center notes the Crapo family to be the biggest impact on Flint. Crapo moved to Flint in the 1850s and had a very successful lumber business. He was elected mayor of Flint in 1860 and then Governor of Michigan for two terms from 1864 to 1869 before retiring. William Crapo Durant, founder of General Motors, is the grandson of Henry and Mary Ann Crapo.

    Now the oddity of Crapo Island appears to be long gone, but I can’t find any reference to when it was removed from the river. In 1907, William Crapo, Henry’s oldest son, presented the island as “Crapo Island Park” to the City of Flint. In 1929, the east channel of the river filled in and Crapo Island became the east riverbank. In 1940, the Flint City Market was built on land that had been part of Crapo Island and the old river channel.

    You can still see how the riverbank bumps out under the 5th Avenue bridge.

  • Mapping Flint: Understanding Flint Geography

    Flint, to me, has always been about family and cars. 

    My great grandfather worked for Chevrolet in what became better known as “Chevy in the hole.” My grandfather worked at the Flint Assembly Plant and was an active member of the UAW. My grandmother’s family opened the first Chrysler dealership in the Flint area in 1926 before running the Oldsmobile dealership.

    Both of my parents grew up in Flint with stories of attending community schools, watching the spark plug parades, and ice skating at Atwood Stadium. Actually five members of my immediate family were born at St. Joe’s hospital which closed in 1997. My dad bought his first home on the Bradley Avenue hills of Crim notoriety. 

    My childhood was spent visiting the Cultural Center of the city, taking trips to the Flint Institute of Arts, Longway Planetarium, or the Flint Public Library, learning to swim at Hurley Health and Fitness, running the Crim, and taking classes at Mott Community College. I attended Powers Catholic when it was located in the North End and often volunteered with the St. Luke Center. Most of my family lived in areas of South End near Miller Road, Thread Lake, and Bristol Road.

    Thinking about all the Flint places important to my own story I tried to come up with a way to quickly reference the geography of the city. North, Downtown, and South area helpful geographic divisions. Specific ZIP codes are easy to know from family and business addresses. How do you represent Flint? What are the ways that you reference where you are in the city?

  • Map: Flint River Indian Reservations 1879

    Flint’s history is that it was a collection of 11 Indian Reservations along the Saginaw Trail next to the Flint River called Grand Traverse Village. Present day Saginaw Street is the bold line noted by the arrow on the map.

    Indigenous burial mounds were documented along the Flint River in the 1830s and archaeological digs in 1899 noted the presence of historic indigenous villages. The names of these villages became enshrined in the Saginaw Treaty of 1819 that established 11 reservations along the Flint River under Governor Lewis Cass. The reservations constituted 7,041 acres of land along the south bend of the river.
