The Chicago Park District maintains weather sensors at beaches along Chicago's Lake Michigan lakefront. These sensors generally capture the indicated measurements hourly while the sensors are in operation during the summer. During other seasons and at some other times, information from the sensors may not be available. See https://data.cityofchicago.org/id/qmqz-2xku for a dataset with similar measurements on the lake water, itself.

Map of 811 Chicago Utility Hit Tickets

Chicago Department of Transportation (CDOT), Division of Infrastructure Management (DIM), operates Chicago’s “One Call” service—known as “811 Chicago.” Per Municipal Code of Chicago (MCC) § 10-21-080, “in the event of damage to any underground facilities, the person responsible for the damage shall immediately notify…811 Chicago.”

811 Chicago records all reported damages as “hit tickets.” This dataset contains hit tickets since January 1, 2020. (Prior to that date, hit tickets data is a less reliable measure of utility damages.)

Please note, a hit ticket does not necessarily mean damage occurred or implicate the parties listed on the hit ticket as having caused the damage. For example, an excavator may report damage they discovered, but did not cause; an entity may incorrectly report the utility that was damaged or who caused the damage; the same damage may be reported by more than one entity. 811 Chicago investigates all reported damages to determine if there was a violation of MCC § 10-21. During the course of its investigation, 811 Chicago will confirm the information on the hit ticket. If 811 Chicago discovers inaccurate information, it may not update the hit ticket. The data related to 811 Chicago’s investigation is not exposed in this data set. Importantly, 811 Chicago does not determine which entity is liable for the damage, and the “hit by” field does not indicate that the individual or entity caused the damage or violated MCC § 10-21.

This dataset displays location for vehicles that have been towed and impounded by the City of Chicago within the last 90 days. Illegally parked vehicles, abandoned vehicles and vehicles used for illegal activities may be towed by the Chicago Police Department, the Department of Streets and Sanitation, the Department of Revenue, Aviation and the office of the City Clerk. After a tow request is issued, an inventory number is assigned by the Department of Streets and Sanitation and a truck is dispatched to tow the requested vehicle to a City auto pound. Disclaimer: This dataset includes vehicles towed or relocated by the City of Chicago; it does not include vehicles towed by a private towing company.
