updated 2 months ago.
In 2009, Data Driven Detroit partnered with Living Cities, the Detroit Office of Foreclosure Prevention and Response and Community Legal Resources (Michigan Community Resources) to conduct a survey of 1-4 unit residential structures and vacant lots in the City of Detroit. Surveyors went out in the field in August and September of 2009, and following this, data were entered into a database and cleaned. The survey collected information on property type, condition, vacancy, danger to the surrounding community, fire damage, and improvements on vacant lots.For more information on the DRPS, including aggregations and maps of the original data, please visit www.detroitparcelsurvey.org.<div><br /></div><div>Upon request, field description metadata is also available for this dataset.</div>

Motor City Mapping, Enhanced File (October 1st Survey Results)
(from Data Driven Detroit Data Portal)

updated 2 months ago.
<div> <p>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."</p> <p>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 www.motorcitymapping.org. 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.</p> <p>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.</p> <p>Metadata accompanying this dataset includes <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/MCM_Enhanced_10012014/Metadata_MCM_Enhanced_10012014.xls" target="_blank">field description metadata</a> and a <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/MCM_Enhanced_10012014/MCM_10012014_Enhanced_Documentation_11242014.pdf" target="_blank">narrative document</a> describing the process of creating the final file.</p> <p>We look forward to seeing how this data can lead to a deeper understanding of Detroit!

updated 2 months ago.
<p>This dataset contains the locations of all properties that have been sold by the Detroit Land Bank Authority through a direct sale to a purchaser (rather than through their side lot or home auction programs). While most housing transactions fall into one of those two categories, a small number have been sold through other programs and means. Information contained in this dataset includes name of purchaser, date of transaction, and the cost the purchaser paid for the property. <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/DLBA_ProgramSales/Metadata_DLBADirectSales.xls" target="_blank">Field description metadata are available for download</a> to provide more detail on the specific contents of the dataset.</p> <p>The analyst downloaded these data in their raw format from the City of Detroit's Open Data Portal on March 31, 2015. The analyst then geocoded the data to spatialize the properties and assign a parcel ID to each record.</p>

Vacancy Index, November 2014 (Aggregated)
(from Data Driven Detroit Data Portal)
Shared by

on December 30, 2014.
updated 2 months ago.
<div> <p>The D3 vacancy index was designed to provide a more nuanced assessment of structural vacancy than the "occupied/unoccupied/maybe" categories used in the Motor City Mapping windshield survey. The dataset includes several sources, including Motor City Mapping, utility data, and other resources to create a score evaluating the occupancy status of a parcel. These values are then coded as "Likely Occupied", "Potentially Vacant", "Likely Vacant", and "Very Likely Vacant", helping to show a spectrum of vacancy across Detroit.</p> <p>Because the vacancy index incorporates proprietary data sources, D3 is unable to release the raw values of the index to the public at the address level. To allow the public to obtain some of the benefit from this highly-effective tool, however, D3 aggregated this data to the Census Tract level. This file allows Detroit's policymakers and community members to track vacancy across the city using data that is as up-to-date as possible.</p><p>Metadata associated with this file includes <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/Vacancy_Index_Aggregation/Metadata_VacancyIndexAggregation.xls" target="_blank">field description metadata</a> and a <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/Vacancy_Index_Aggregation/VacancyCount_Aggregated_Documentation_Final_12302014.pdf" target="_blank">narrative summary</a> documenting the creation of the dataset.</p></div>
