CDPH Environmental Records Lookup Table CDPH Environmental Records Lookup Table 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.

Average Daily Traffic Counts Average Daily Traffic Counts Transportation
Average Daily Traffic (ADT) counts are analogous to a census count of vehicles on city streets. These counts provide a close approximation to the actual number of vehicles passing through a given location on an average weekday. Since it is not possible to count every vehicle on every city street, sample counts are taken along larger streets to get an estimate of traffic on half-mile or one-mile street segments. ADT counts are used by city planners, transportation engineers, real-estate developers, marketers and many others for myriad planning and operational purposes. Data Owner: Transportation. Time Period: 2006. Frequency: A citywide count is taken approximately every 10 years. A limited number of traffic counts will be taken and added to the list periodically.

Chicago Police Department - Illinois Uniform Crime Reporting (IUCR) Codes Chicago Police Department - Illinois Uniform Crime Reporting (IUCR) Codes Public Safety
Illinois Uniform Crime Reporting (IUCR) codes are four digit codes that law enforcement agencies use to classify criminal incidents when taking individual reports. These codes are also used to aggregate types of cases for statistical purposes. In Illinois, the Illinois State Police establish IUCR codes, but the agencies can add codes to suit their individual needs. The Chicago Police Department currently uses more than 350 IUCR codes to classify criminal offenses, divided into “Index” and “Non-Index” offenses. Index offenses are the offenses that are collected nation-wide by the Federal Bureaus of Investigation’s Uniform Crime Reports program to document crime trends over time (data released semi-annually), and include murder, criminal sexual assault, robbery, aggravated assault & battery, burglary, theft, motor vehicle theft, and arson. Non-index offenses are all other types of criminal incidents, including vandalism, weapons violations, public peace violations, etc.
