In order to help contractors and private residents avoid existing utility lines (including gas, electrical, and water lines) when digging, the Chicago Department of Transportation maintains 811 Chicago, a free, 24-hour service to private contractors and homeowners in Chicago. Anyone planning to dig within Chicago must obtain a “dig ticket” from 811 Chicago. 811 Chicago notifies all utilities of the impending excavations. The utility owners then send out staff to mark the location of the underground facilities within 48 hours (excluding emergencies), not counting Saturdays, Sundays, and holidays.

The dataset on which this filtered view is based shows these utility notifications. Since it is common for the same dig ticket to produce multiple notifications, the same dig ticket will appear multiple times and the dataset cannot be used without further refinement to count, map, or analyze unique excavations in Chicago.

This filtered view shows only the columns that should remain constant for a dig ticket and de-duplicates them, Therefore, it should represent a unique list of dig tickets. Because of the technique used, while it is possible to show the LATITUDE and LONGITUDE columns, it is not possible to show the LOCATION column and therefore not possible to create map views directly from this filtered view within the data portal software.

See https://ipi.cityofchicago.org/Digger for more information on the dig ticket system.

Bike racks in Chicago.

This dataset contains bike racks installed between 2015-2021. There is another dataset from 2011 at https://data.cityofchicago.org/d/cbyb-69xx that shows bike racks in existence at that time. We hope eventually to consolidate the data into this dataset.

Applications to the Chicago Department of Transportation for permits under its jurisdiction, which 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.

These feeds of information help developers to get the latest information about planned and unplanned events that affect CTA services.
