The City of Chicago has released a handful of new datasets which pertain to several parts of daily life in Chicago. The public will be able to explore the water quality at Chicago beaches, find who and which vehicles are licensed to carry passengers, activities for Chicago’s Micro-Market Recovery Program, and the geographic areas targeted by the City’s Broadband Innovation Challenge.

Sensors at Chicago’s Beaches

Chicago Parks District maintains automated sensors that report water data at the city’s beaches, including water temperature, water clarity (turbidity), and wave height–the same information 
The new dataset provides current and historical information from sensors starting during the 2014 swimming season. The graph below shows water temperatures every hour for each Chicago beach from Memory Day 2014 until present

These sensors will go offline during the winter, but the data will remain and be active each summer.

Public Chauffeurs, Vehicles, and Pedicabs

Every day, licensed chauffeurs carry Chicago residents in taxis, limousines, and even horse-drawn carriages and pedicabs. Each driver is licensed by the City of Chicago’s Department of Business Affairs and Consumer Protection (BACP). Now, a dataset on the portal shows the licensed chauffeurs in the city and the vehicles authorized to carry passengers.

The public chauffeurs dataset lists which drivers have applied for a chauffeurs permit to operate ambulances, horse-drawn carriages, pedicabs, taxis, and livery vehicles (e.g., limos).

Meanwhile, public passenger vehicle licenses show which vehicles are authorized to carry passengers. The make, model, and year of vehicle is shown, including the vehicle color and type of fuel the vehicle uses. The graph below shows the most popular model for taxi cabs with an active license.

Additionally, the data also shows if the vehicle is wheelchair accessible, the name of the company which owns the vehicle and their address is also available through this dataset.

Finally, the dataset also includes permits recently issued by BACP in response to a new city ordinance. Individuals who applied to pedicab licenses are displays alongside other public chauffeur applicants. Want to just view pedicab permits?

Micro-Market Recovery Program

The portal contains several datasets on the Micro-Market Recovery Program (http://www.cityofchicago.org/city/en/depts/dcd/supp_info/micro_market_recoveryprogram.html) in the City of Chicago. The city has identified several MMRP zones to provide real estate purchasing assistance to stabilize the local housing market. Community development organizers work to provide residents the ability to buy vacant or abandoned properties from absentee landowners and banks to revitalize neighborhoods.

The MMRP data consists of five different datasets covering addresses, building permits, cases, and violations and inspections of properties within MMRP zone. A map of the boundaries for each MMRP zone is also available.

Need to link data, for instance, matching violations with cases? You can join the data using the address_key or address_grouping_key fields.  Below is a diagram showing the relationship between these tables.

Broadband Innovation Zones

Last year, the City released a request-for-qualifications for companies to build gigabit or near-gigabit broadband in designated innovation zones at affordable prices. We’ve posted a machine-readable, GIS map on the broadband innovation zones. Maps can be explored within your browser, so you won’t need to use special GIS software to view the innovation zones.
