This file corrects several problems in the original TIGER/line files, notably the inclusion of parts of Lake Michigan within the city limits, and the numerous irregularities that are a function of the way the TIGER/line files were created. This file will consequently not line up with TIGER/line streets or tracts; it will line up with the 1992 ward boundary file. Its author is Christopher Siciliano.

This map is part of a collection of 10 maps showing the location of Presbyterian Churches in relation to ethnic groups in the city of Chicago. The manuscript title is "The effects of subsity of Presbyterian Churches", by Henry Hughes Presler, and can be found at Mansueto Library, University of Chicago under the call number BX 10999. These maps have been outlined and vectorized as the originals, and points placed for location of churches as they were in the original. Call number for the maps: G4104.C6E1 1948.H6. Map Collection, Regenstein Library, University of Chicago. Drawn from Map 7 - Location of Presbyterian churches in relation to ethnic groups in the city of Chicago, by Census Tracts, 1920.

Applications to the Chicago Department of Transportation for permits under its jurisdiction where the work type is "Filming." These permits typically are permits to block or otherwise affect public streets in some way. Because all permits start as applications, this dataset also serves as a list of permits granted. See more information about CDOT permits at http://www.cityofchicago.org/city/en/depts/cdot/provdrs/construction_information/svcs/online-permit-portal.html.

Ward boundaries in Chicago from May 2003 to May 2015, corresponding to the dates when a new City Council is sworn in, based on the immediately preceding elections. Neither this description nor the dataset should be relied upon in situations where legal precision is required. The data can be viewed on the Chicago Data Portal with a web browser. However, to view or use the files outside of a web browser, you will need to use compression software and special GIS software, such as ESRI ArcGIS (shapefile) or Google Earth (KML or KMZ), is required.

This dataset and corresponding map provide the location, satellite images and square footage of existing green roofs within the City of Chicago. This information is derived from an analysis of high-spatial resolution (50cm), pan-sharpened, ortho-rectified, 8-band multi-spectral satellite images collected by Digital Globe’s Worldview-2 satellite. The City supplied the consultant with a 2009 City boundary shapefile to determine the required extent of the imagery. Acquisition of three different strips of imagery corresponding to the satellite’s paths was required. These strips of imagery spanned three consecutive months and were collected in August 2010 (90% coverage), September 2010 (5% coverage) and October 2010 (5% coverage). The results of the analysis include overall count of vegetated roofs, their total square footage, and the ratio of required to elective vegetated roofs. A total of 359 vegetated roofs were identified within the City of Chicago. The total square footage of these vegetated roofs was calculated to be approximately 5,469,463 square feet. The ratio of required vegetated roofs to elective vegetative roofs was 297:62 (~5:1). The median size of the vegetated roofs was calculated to be 5,234 square feet.

Preference boundaries for selected charter schools in the Chicago Public Schools district for school year 2019-2020. As opposed to elementary or high school attendance boundaries wherein each residing student is entitled to attend, charter boundaries simply serve as a guide for charter school administrators to use during the application/lottery process. Applicants residing within a specific boundary are generally given preference over applicants residing outside of the boundary.

DISCLAIMER:Subregional Councils of Mayors (COM) boundaries are a hybrid of county and municipal boundaries. The council boundaries are based on the membership of municipalities within a subregional council. County boundaries are followed in unincorporated areas. For municipalities designated as belonging to more than one council, the county boundary is followed. Example 1: the City of Naperville is a member of the DuPage Council of Mayors; since Naperville city limits extend into Will County, the DuPage COM boundary follows the Naperville boundary (including all unincorporated pockets) in Will County. Example 2: Buffalo Grove belongs to both the Lake County and Northwest subregional councils; in this case, the subregional boundary follows the county boundary through Buffalo Grove.It is important to note here that the portions of COM boundaries, defined by municipalities, are fluid: they change as a village annexes adjacent unincorporated land. The boundaries depicted in this shapefile reflect municipal boundaries of varying vintages and sources, and cannot be considered “true” for any given point in time. For more information please visit the Subregional Councils page on the CMAP website: http://www.cmap.illinois.gov/web/guest/about/involvement/committees/advisory-committees/council-of-mayors/subregional-councils.

The Historical Urban Ecological (HUE) data project was created for exploring and analyzing the urban health environments of seven major United States cities - Baltimore, Boston, Brooklyn, Chicago, Cincinnati, Manhattan, and Philidelphia - from 1830 through 1930. The data for each city includes ward boundary changes, street networks, and ward-level data on disease, mortality, crime, and other variables reported by municipal departments. The HUE data set was produced for the "Early Indicators of Later Work Levels, Disease and Death" project, funded by the National Institute of Aging. This collection represents the GIS data for each of the seven American cities, and in addition to ward boundary changes and street networks, includes in-street sewer and water sanitation systems coverage. All cities except Cincinnati include sanitation infrastructure data, and for Baltimore only water infrastructure is available. The city of Chicago includes supplemental GIS layers which reflect a reconstruction of two of Homer Hoyt's maps of average land value (1933 dollars) in the City of Chicago for 1873 and 1892. The square mile areas defined by Hoyt using Chicago's system of mile streets have been fit to the HUE street centerlines for Chicago. The Excel data tables include information about deaths in each ward broken down by cause of death, age, race, gender, as well as information about live births and deliveries.
