The Annual Appropriation Ordinance is the final City operating budget as approved by the City Council. It reflects the City’s operating budget at the beginning of the fiscal year on January 1. This dataset details the budgeted expenditures in the Ordinance and identifies them by department, appropriation account, and funding type: Local, Community Development Block Grant Program (CDBG), and other Grants. “Local” funds refer to those line items that are balanced with locally generated revenue sources, including but not limited to the Corporate Fund, Water Fund, Midway and O’Hare Airport funds, Vehicle Tax Fund, Library Fund and General Obligation Bond funds. Owner: Budget and Management. Frequency: Data is updated annually. For more information about the budget process, visit the Budget Documents page: http://j.mp/lPotWf.

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. The sensor locations are listed at https://data.cityofchicago.org/d/g3ip-u8rb.

This dataset lists monthly station entry averages, by day type (Weekday, Saturday or Sunday/Holiday), as well as monthly totals, beginning in 2001. Note that some stations (such as on the Cermak Branch--now Pink Line) and Skokie did not have Saturday and/or Sunday/holiday service until more recent years, although, in cases where weekday service ran past midnight, late evening fares may appear as part of Saturday tallies.

This information is derived from payments made to City of Chicago employees from January 1 of the previous calendar year to the present. Payments are initiated by City Departments and issued by the Department of Finance. Descriptions of each attribute follow:

- Voucher Number: This is a unique number assigned to each payment and is used for identifying that particular payment.

- Amount: This is the dollar amount of the payment made.

- Payment Date: This is the date payment was issued.

- Vendor Name: This is the name of the person or entity to which payment was made.

- Description: This is an optional field that indicates the reason payment was made.

This dataset contains the historical estimated congestion for 1270 traffic segments, in selected time periods from August 2011 to May 2018. Newer records are in https://data.cityofchicago.org/d/sxs8-h27x. The most recent estimates for each segment are in https://data.cityofchicago.org/d/n4j6-wkkf.

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. Current estimates of traffic congestion by region are available at http://bit.ly/Vz3rIh.

The Annual Appropriation Ordinance is the final City operating budget as approved by the City Council. It reflects the City’s operating budget at the beginning of the fiscal year on January 1, 2013.This dataset displays the positions and related salaries detailed in the budget as of January 1. It is extracted from the personnel portion of the Appropriation Ordinance. The dataset presents the position titles (without names) and salaries described in the budget, but does not provide a reflection of the current city workforce with full names and salaries. Disclaimer: the “Total Budgeted Units” column displays either A) the number of employees AND vacancies associated with a given position, or B) the number of budgeted units (ie. hours/months) for that position. “Position Control” determines whether Total Budgeted Units column will count employees and vacancies or hours/months. If a Position Control is 1, then employees and vacancies are displayed; if a Position Control is 0, then the total number of hours/months recorded is displayed. Owner: Budget and Management. Frequency: Data is updated annually. For information on the current city workforce, with names, positions and salaries, visit the "Current Employee Names, Salaries, and Position Titles" dataset: http://j.mp/iutKlR.

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 Violations and Inspections dataset contains Department of Buildings (DOB) Violations and associated Inspections that have occured at properties falling within an 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 and link to Permits APKEY_PERMIT and Cases APKEY_CASE. *Note: Inspections are included only when at least one violation was written. Inspections without violations are not included in this dataset.
