Description: In the fall of 2013, the Detroit Blight Removal Task Force commissioned Data Driven Detroit (D3), the Michigan Nonprofit Association, and LOVELAND Technologies to complete a survey of every parcel in the City of Detroit. This effort, called Motor City Mapping, leveraged relationships with the Rock Ventures family of companies and the Detroit Employment Solutions Corporation to assemble a dedicated team of over 200 resident surveyors, drivers, and quality control associates. From December 4, 2013, to February 16, 2014, the team collected data on over 370,000 properties, including information on use and condition of structures, fire damage, boarding, and the presence of dumping. This dataset formed the centerpiece of the Blight Removal Task Force's report, "Every Neighborhood has a Future...and It Doesn't Include Blight."Following the completion of the survey, D3 and LOVELAND have continued to collaborate on a second phase of the Motor City Mapping project, involving the build-out of a technology infrastructure intended to keep the data updated as conditions change across the city. LOVELAND issued a public release of the "Blexting" application used to conduct the initial survey, allowing Detroit's residents, workers, and community organizations to survey properties across the city. Responses, or "blexts", are reviewed by a quality-control team to ensure that the information is consistent with the standards set forth by D3 and LOVELAND, and then are displayed publicly on This file consists of the most recent "blext" for each parcel through October 1, 2014, the date that responsibility for surveying and quality control transitioned from D3 to LOVELAND.In addition to the MCM dataset, D3 has enhanced this file with several other datasets, including 2014 tax foreclosures and delinquency, likely public ownership, and building footprint information. The tax foreclosure data flags properties that were likely headed to Tax Foreclosure as of August, 2014, while the tax delinquency data dates to June, 2014. Likely public ownership identifies properties identified by one of several sources as being owned by a public entity as of 2013/2014, while the building footprint information has been aggregated to parcel and dates to 2008.Metadata accompanying this dataset includes field description metadata and a narrative document describing the process of creating the final file.We look forward to seeing how this data can lead to a deeper understanding of Detroit!
