311 Service Requests - Vacant and Abandoned Buildings Reported - Map 311 Service Requests - Vacant and Abandoned Buildings Reported - Map Service Requests
Data set contains all 311 calls for open and vacant buildings reported to the City of Chicago since January 1, 2010. The information is updated daily with the previous day's calls added to the records. The data set provides the date of the 311 service request and the unique Service Request # attached to each request. For each request, the following information (as reported by the 311 caller) is available: address location of building; whether building is vacant or occupied; whether the building is open or boarded; entry point if building is open; whether non-residents are occupying or using the building, if the building appears dangerous or hazardous and if the building is vacant due to a fire.

311 Service Requests - Street Lights - One Out 311 Service Requests - Street Lights - One Out Service Requests
This dataset contains all open 311 reports of one or two lights out on metal poles on a residential or arterial street and all completed requests since January 1, 2011. Whenever CDOT receives a report of a street light outage, the electrician assigned to make the repair looks at all the lights in a group (circuit) to make sure that they are working properly. If two requests regarding the same group are made within 30 calendar days of each other, the newest CSR is automatically given the status of “Duplicate (Open).” Since the electrician will be looking at all the lights in a group to verify that they are all working the “Duplicate (Open)” address will also be observed and repaired. Once the street lights are repaired, the CSR status will read “Completed” for the original request and “Duplicate (Closed)” for any duplicate requests. Data is updated daily.
Chicago Traffic Tracker - Congestion Estimates by Regions Chicago Traffic Tracker - Congestion Estimates by Regions Transportation
This dataset contains the current estimated congestion for the 29 traffic regions. For a detailed description, go to: http://bitly.com/TeqrNv. The Chicago Traffic Tracker estimates traffic congestion on Chicago’s arterial streets (non-freeway streets) in real-time by continuously monitoring and analyzing GPS traces received from Chicago Transit Authority (CTA) buses. Two types of congestion estimates are produced every 10 minutes: 1) by Traffic Segments and 2) by Traffic Regions or Zones. Congestion estimates by traffic segments gives observed speed typically for one-half mile of a street in one direction of traffic. Traffic Segment level congestion is available for about 300 miles of principal arterials. Congestion by Traffic Region gives the average traffic condition for all arterial street segments within a region. A traffic region is comprised of two or three community areas with comparable traffic patterns. 29 regions are created to cover the entire city (except O’Hare airport area). There is much volatility in traffic segment speed. However, the congestion estimates for the traffic regions remain consistent for a relatively longer period. Most volatility in arterial speed comes from the very nature of the arterials themselves. Due to a myriad of factors, including but not limited to frequent intersections, traffic signals, transit movements, availability of alternative routes, crashes, short length of the segments, etc. Speed on individual arterial segments can fluctuate from heavily congested to no congestion and back in a few minutes. The segment speed and traffic region congestion estimates together may give a better understanding of the actual traffic conditions.
Green Roofs - Map Green Roofs - Map Environment & Sustainable Development
This map and corresponding dataset 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.
CDPH Environmental Records Lookup Table - Map CDPH Environmental Records Lookup Table - Map Environment & Sustainable Development
This dataset serves as a lookup table to determine if environmental records exist in a Chicago Department of Public Health (CDPH) environmental dataset for a given address. Data fields requiring description are detailed below. MAPPED LOCATION: Contains the address, city, state and latitude/longitude coordinates of the facility. In instances where the facility address is a range, the lower number (the value in the “Street Number From” column) is used. For example, for the range address 1000-1005 S Wabash Ave, the Mapped Location would be 1000 S Wabash Ave. The latitude/longitude coordinate is determined through the Chicago Open Data Portal’s geocoding process. Addresses that fail to geocode are assigned the coordinates 41.88415000022252°, -87.63241000012124°.This coordinate is located approximately just south of the intersection of W Randolph and N LaSalle. COMPLAINTS: A ‘Y’ indicates that one or more records exist in the CDPH Environmental Complaints dataset. NESHAPS & DEMOLITON NOTICES: A ‘Y’ indicates that one or more records exist in the CDPH Asbestos and Demolition Notification dataset. ENFORCEMENT: A ‘Y’ indicates that one or more records exist in the CDPH Environmental Enforcement dataset. INSPECTIONS: A ‘Y’ indicates that one or more records exist in the CDPH Environmental Inspections dataset. PERMITS: A ‘Y’ indicates that one or more records exist in the CDPH Environmental Permits dataset. TANKS: A ‘Y’ indicates that one or more records exist in the CDPH Storage Tanks dataset. Each 'Y' is a clickable link that will download the corresponding records in CSV format.

Micro-Market Recovery Program - Permits - Map Micro-Market Recovery Program - Permits - Map Community & Economic Development
The City of Chicago launched the Micro-Market Recovery Program (MMRP), a coordinated effort among the City, not-for-profit intermediaries, and non-profit and for-profit capital sources to improve conditions, strengthen property values, and create environments supportive of private investment in targeted markets throughout the city. The goal of MMRP is to improve conditions, strengthen property values, and create environments supportive of private investment in targeted areas by strategically deploying public and private capital and other tools and resources in well-defined micro-markets. This MMRP Permits dataset contains all Department of Buildings (DOB) Permits that have occured at properties falling within any MMRP Zone. Permits, Cases and Violations can be linked to the MMRP Geographies dataset using ADDRKEY or ADDRGRPKEY. To link Violations and Inspections to their Permits and Cases use Violation PERMITORCASEKEY to link to Permits APKEY_PERMIT and Cases APKEY_CASE. For more information on the MMRP program, please see http://www.regionalhopi.org/content/city-chicago-micro-market-recovery-program-overview.
