RENEE MONTAGNE, HOST:
Detroit is in the midst of mapping its own decay. The city is trying to figure out exactly how many abandoned homes and buildings it has, and then decide which ones to tear down and which ones to spare. It's a new approach to the city's longstanding problem in the midst of the largest-ever municipal bankruptcy. Quinn Klinefelter, of member station WDET, reports.
QUINN KLINEFELTER, BYLINE: Inside one in a series of abandoned homes along a blighted block of Detroit's Brightmoor neighborhood, filmmaker Tom McPhee walks through the remnants of a life: broken furniture, scattered knickknacks and a flooded basement.

TOM MCPHEE: This is fresh water that's coming into the basement here. All of that plumbing has been ripped away because someone found a value in it. So they don't care that it's running. This is all over the city.
KLINEFELTER: McPhee helps catalog blight in Detroit, but the sheer size of this city makes it hard to pin down. Detroit has 380,000 parcels of land stretched across 139 square miles, so many parcels that its antiquated computer system can't keep up. Last fall, White House officials created a Blight Task Force here, in partnership with some private foundations, to determine just what property is salvageable.

KLINEFELTER: Now, that information is pouring into here - a long room with dozens of people poised over laptops. A map of Detroit covers one table and is replicated on the laptop screens, overlaid by a computer grid of the city.
LAUREN HOOD: Here's the map, right here. And these blue dots represent surveyors that are out in the field. So they're all over the city right now.
KLINEFELTER: Lauren Hood is with Loveland Technologies, which developed a new way of mapping Detroit. They call it blexting: sending teams throughout the city to text pictures and descriptions of blight to a database. She says in a few months, that data will be available as an app for anyone to access or correct.
HOOD: People that actually live in the neighborhoods can respond to what's been said about their neighborhoods, and add to it or change it or update it. They can have the power.
KLINEFELTER: Nearby, supervisor Mark Weaver remembers meeting residents whose initial suspicion quickly changed to hope once he described the project's goals. He says the feeling of despair in these neighborhoods can be palpable.
MARK WEAVER: You're seeing people who just gave up. They moved away. They gave up their homes. And it becomes like a domino effect because once all of your neighbors begin moving out, then you think, why should I stay here and maintain my home when I'm surrounded by blight and terror?
KLINEFELTER: Detroit officials spent decades trying to tear down such homes, but each demolition costs between 5- and $10,000. The mapping project's manager, Sean Jackson, says the new database will help them better use the scarce funding by compiling information that the city and county departments' outdated computers could never integrate.
SEAN JACKSON: And a lot of times, they might own a couple properties next to each other, and they just don't know that they all own a house on the same block. So now, we can actually show them, hey, all four of you guys, all four different departments, you all have property on this street. If you're going to send in a demo crew, instead of sending them in four different times, why don't you all put your properties together and do all four of them at the same time, so you can help get some cost savings and be able to work together on solving these problems?
KLINEFELTER: That's the kind of information new Detroit Mayor Mike Duggan says he's waiting for. Despite a state-appointed emergency manager making all of the financial decisions for the city, Duggan vows to use what power he retains to make Detroit a more attractive place to live, beginning by bringing anti-blight agencies under a single Land Bank Authority. But the mayor says he needs the information from the mapping database to improve Detroit beyond its thriving downtown and midtown areas.
MIKE DUGGAN: Everything starts with the neighborhoods. And so we're going to build a legal team at the Land Bank to do what I was doing when I was in the prosecutor's office - with lawyers who go in and sue the owners of the abandoned houses, knock down the ones that can't be fixed, sell the ones that can, and move through this city on a systematic basis.
KLINEFELTER: At least one decision already appears to have been made. Remember the flooded basement inside the abandoned home in Brightmoor? Once abandoned homes are removed, water service will be turned off to those areas permanently.
