When state experts sat down with Flint planners two days after Gov. Rick Snyder declared a water
emergency, they asked about the locations of lead water pipes connecting to residents’ homes.
The information was mostly there, on paper, filed in a large vault. There are hundreds of hand-drawn
plat maps from the 1980s and hand-written notes on thousands of cards about updates to home
plumbing systems.
Over the years, a dedicated Flint city employee has been translating inspectors’ handwritten notes
about plumbing updates into an Excel spreadsheet. But like many cities with limited budgets, Flint
doesn’t have a robust staff converting the information from paper to searchable data.
All that paper is now being be digitized so the State Emergency Operations Center can figure out where
safe water is needed.
Five GIS analysts are working on the project — including one from FEMA, which entered the picture after
President Obama granted Gov. Snyder’s request for a federal emergency on Jan. 16.
Mapping infrastructure to this depth of detail is highly unusual, said James Tchorzynski, manager of the
GIS analysts for the Emergency Management and Homeland Security Division of the Michigan State
Police.
In a disaster like severe flooding, “You’re used to watching the water rise and you count the houses.
Here, it’s all underground.”
Once the maps are in digital format, they’re synched with 2015 parcel data. Then they can be overlayed
with Census information and infrastructure information, allowing analysts to pinpoint which inhabited
homes have lead service lines.
That has been the job of Scott Bailey, a FEMA GIS analyst, for the past several days.
“The state is doing a great job of collecting the data,” said Scott Bailey, a GIS data analyst with FEMA
helping with the mapping project. “That’s going to be a success story that comes out of this. They're
able to upload large amounts of data in a matter of hours.”
Credit goes to the ArcGIS Online app that the state is using to upload home data in real time.
Teams going door to door to deliver water supplies to residents are armed with iPads and the app,
which feeds into the GIS system, noting whether there are children in the household and which ones
have been provided with bottled water, a water test kit, a water filter and replacement cartridges.

HOW MANY SO FAR WITH LEAD SERVICE LINES? 3,600 OUT OF 26,000??////
The app information also helps Nikkia Anderson, a Michigan State Police GIS data analyst who is
determining the number of inhabited homes in a city severely affected by blight.
