We can't wait to show you and hopefully get you on the system! It's sort of freaking us out how sweet it is.
This time around I wanted to try out StoryMap -- the Knight Lab's fabulous contribution to displaying a series of events on a map supported by video, photography, social media, and text. For a subject matter to explore, I thought I'd take a look at a week's worth of structure damaging fires in Detroit.
Surveyors working on Motor City Mapping keep close tabs on every structure damaging fire in Detroit -- each is surveyed usually within a day of the fire. The city is especially vulnerable to structure damaging fires -- arson in Detroit is a well known and persistent problem.
Telling this story is challenging. Conveying the scale of damage across the size of the city, the challenges faced by the Detroit Fire Department... Detroit's Motor City Muckraker has taken on the task of documenting each of the city's fires, and while StoryMap wouldn't be ideal for presenting thousands of fires, it is perfect for presenting a slice of time that is indicative of the whole. In the map above you'll see 53 structure fires over seven days in Detroit. Typically Detroit averages 14 fires / day, the week above is around 8 / day.
As I started building my StoryMap I realized I was following a very repetitive process -- saving the image, titling the photo with the address, copy & pasting the notes. My colleague, Mike Evans, saw what I was doing and said, "Hey stop that, I bet we can publish automatically from Site Control."
Site Control is LOVELAND's (coming soon) software that gives you access to all the parcels and data that we present publicly, but in your own private LOVELAND universe. You can develop your own survey questions, pipe in data from open data portals, build and color code parcel maps, and build queries of the information in your maps.
Once you've done all that in Site Control, we want to give you options if you want to share and publish your maps. Of course Site Control maps are embeddable, or shareable in read-only formats, but now, you can also publish a Site Control map to StoryMap. That's what you see above. Thanks to some deft and thoughtful work by Mike, you can select data and photography in Site Control that you want published, and your StoryMap will generate with the selected content.
Even better, if you publish a StoryMap via Site Control and then continue surveying property in the Site Control map you've connected to your StoryMap, the new imagery and information will pipe into your StoryMap automagically.
We're still working on some things -- like making sure the progression through the story map matches the chronology of data in your Site Control map -- but this little proof of concept was too interesting not to share. More to come!
Scanning some parcel data for El Paso County, Texas (a newer edition to the LOVELAND explorer), I noticed a lot of subdivisions with larger parcels around them. When I turned on the satellite view I thought we had some bad data for a moment: thousands of subdivided parcels in the middle of the desert. Not only are there parcels with no structures, but sometimes no actual roads underneath, just the outlines of roads which should be there based on the parcels themselves. That is when I discovered the cautionary tale of real estate investment gone wrong.
It turns out these desert parcels are no accident but instead spearheaded by a devious real estate corporation of the 1960’s. The company was called Horizon Corp., and back between 1962 through 1975 it “was one of the largest sellers of undeveloped land in the Southwest” ( El Paso Times, 2011). Unfortunately for those who purchased plots of land from Horizon Corp. in the middle of undeveloped Texas desert, there would never be any development of utilities like water, electricity and roads. People from all over the world encountered extremely aggressive salesmen from Horizon Corp., the kind who likely would sell you two encyclopedia sets, the second just to get them to leave.

If this were not enough, it turns out those who own the parcels of land are now stuck with them due to a Texas law attempting to solve a different issue. The Colonia Act of 1994 makes the selling of properties impossible if they do not contain water and utilities. Worthy of further investigation for a later story, Colonias are an issue in Texas, as they are developments primarily along the Mexican-American border that have substandard services and utilities, are often in floodplains or other undesirable lands, and have homes constructed by the residents themselves with haphazard building materials. Though this was never the intention of the subdivisions of Horizon, the parcels of land nevertheless fit the criteria since they are without utilities.
Using the LOVELAND explorer tool enables entities like the Horizon Communities Improvement Association to further plan how to handle these properties. As the homeowner association of the area, they have assembled properties from owners in order to offer larger lots to developers to actually develop the land as habitable properties. Regardless of what becomes the fate of the Horizon City area, it is fascinating to view these desert ghost parcels of El Paso and discover other parcel mysteries in America.

A Property Surveying Time Machine
The ability to drop in on almost any corner of America via Google Street View is an unprecedented and, we at LOVELAND Technologies think, under appreciated bit of magic. But it was the release of Street View's "Time Machine" feature last year that turned the magic of Street View into a full on superpower, letting you rewind and see a city's recent past.
By combining Street View's Time Machine with LOVELAND's suite of parcel mapping and surveying tools that let you collect and visualize lots of parcel data quickly, you can monitor a neighborhood, a city, or a whole country's change over time, trace its trajectory, find causes for growth or decline, and reveal problems before they metastasize. It's a powerful concoction. We tested it out in the Detroit neighborhood shown in the parcel map above.
The Experiment and The Tools
Over the weekend, I surveyed a 190 property area on Detroit's east side, just across the street from the shuttered Alexander Macomb Elementary School. I knew from Motor City Mapping (a project LOVELAND worked on in which we surveyed all 385,000 properties in Detroit) that the area was distressed and had a high vacancy rate, as the neighborhood at large does. What I didn't know, and wanted to try to find out, is:
When did people start to leave the neighborhood, and are they leaving in greater numbers now, or in the past?
What factors might have informed, or forced, their departure?
What is the impact of all this vacancy on property values?
To figure this out, I surveyed the area in 2008, 2011, and 2013 (via Google Street View) and present day (April 2015) with surveyors in the field using the LOVELAND App*. For every parcel, I recorded whether there was a structure on the site, whether the structure appeared occupied, and, if a structure was present, whether it was fire damaged and to what extent. These are all pretty quick indicators of a Detroit neighborhood's overall health.
Unfortunately, Google's Street View API does not support access to Time Machine imagery, so for 2008 and 2011 I sat there like a goof, taking pictures of my computer screen with the LOVELAND App (pretending like I was out in the field surveying property) and collecting survey data. For 2013, which the Street View API does support, I contributed to LOVELAND's Great American Parcel Survey, and surveyed the 190 properties in a wonderfully speedy hour (an example of that survey process is animated below).
I used LOVELAND's Site Control platform to visualize data on each of the 190 properties in the neighborhood for each of the years surveyed. Site Control is LOVELAND's parcel mapping platform that gives you the tools to work with parcel data and build parcel maps anywhere in the country where we have coverage. I built a series of maps with Site Control that shows properties color coded as either vacant lots, occupied homes, or vacant homes. You can explore the maps for each year at the bottom of the post, and click parcels to see data and imagery for that year.
The chart above shows the breakdown of occupied homes, vacant homes, and vacant lots for each year surveyed. The surge from 2008 to 2015 of between 41 and 46 vacant homes is shocking (ambiguity due to demolitions and properties with unclear occupancy status) but it's worth noting a perhaps less obvious number, too: In 2008 there were 62 vacant lots in this neighborhood. At some point, many of these properties likely had a single family home on them.
Detroit, of course, has been in decline for decades, but the financial crisis unleashed a new and virulent wave of devastation on the city that is still rumbling through with potent aftershocks. With Street View, which started collecting imagery at the very moment the 2008 financial crisis began, and LOVELAND's tools, we can see just how this latest collapse unfolded, and some of where it's heading. To return to the initial questions:
When did people start to leave the neighborhood, and are they leaving in greater numbers now or in the past?
Clearly the steepest population drop occurred between 2008 and 2011. Though the slope is still downward from 2011 to 2015, it is trending towards a tapering off, or at least a deceleration. So, it seems safe to say that the most dramatic population loss occurred in the year or two following the financial crisis.
What factors might have been informing, or forcing, residents' departure?
There are plenty of reasons one might have left Detroit just after the financial crisis -- jobs, crime, education (Alexander Macomb Elementary closed its doors in 2009, and certainly could have contributed a reason not to stay in the area), to name a few. One force unique to Detroit is tax foreclosure -- 62,000 properties in the city face foreclosure in 2015.
There has always been something of a chicken or the egg dynamic with tax foreclosure: Do vacant properties fall to tax foreclosure because their former residents left and are no longer paying property taxes? Or do residents become unable to pay property taxes, and wind up leaving once they've lost their homes to foreclosure, or perhaps are forced from their homes by speculators?
By surveying tax foreclosed properties both before and after their foreclosure, as we did here via Street View, we can see the order of operations, and develop a more informed understanding of how tax foreclosure and vacancy interact. (Of course, this should be tested across a larger sample size, but the results are revealing at this small scale.)
In 2012, thirteen properties from the surveyed neighborhood were tax foreclosed. As the graph below shows, vacancy amongst those thirteen properties cropped up both before and after their foreclosure, and in equal number.
By 2011, four homes that were occupied in 2008 had gone vacant -- a year before the actual foreclosure date (there is a three year fuse on tax foreclosure, so presumably residents may have known it was coming). By 2013, one year after foreclosure, another three homes were added to the vacancy list. The four homes that remain occupied did so in an interesting way -- they were all foreclosed, and all four passed through the foreclosure auction without a bid. Today, all four remain occupied and are owned by the City of Detroit.
Though this is a small sample size, it rings true with our experience monitoring tax foreclosure across the city: Tax foreclosure is both a cause, and symptom, of vacant properties in Detroit. In what proportion this is the case would be very valuable to examine across a number of different kinds of neighborhoods.
Property speculation, the practice of bidding on auction properties from afar in expectation that they will be worth more later with no effort for the buyer, does not appear to have been the cause of any vacancy in this neighborhood: Of the 34 properties in the area that went to foreclosure auctions between 2011 and 2014, only one property sold -- for $500.
26 of those 34 foreclosure properties are now vacant homes owned by the City of Detroit -- properties that will likely need to be demolished at a priced tag of $10,000 - $15,000 per home.
What is the impact of all this vacancy on property values?
Detroit Assessor's data does not show a property sale in this neighborhood since the $500 purchase of a foreclosed property in 2013. Another 15 properties in the area face tax foreclosure in 2015, three of which are occupied. Of the 66 occupied homes that remain, 23 are next door to, or back up to, a vacant structure, putting these properties at increased risk of fire damage among other hazards of being in close proximity to vacant properties.
Below is a scatterplot of available sales data for properties in the survey area (note this graphic only includes the latest sale, not ALL sales), with trendlines showing the weight of property sales trajectory.
If foreclosure begets more vacancy, and vacancy leads to more foreclosure, a vicious cycle driving down property values will continue.
We're only scratching the surface of what time series survey data can do when collected at scale, at the parcel level, and merged with governmental data like foreclosure information, tax assessments, and more. The flip side of surveying Detroit's decline is looking at the rapid development of growing cities. Across the country there is a wealth of information contained in the archive that is Google Street View, and with LOVELAND's tools and ability to organize and present property data, there are insights close at hand.
