The following dataset includes "Active Benchmarks," which are provided to facilitate the identification of City-managed standard benchmarks. Standard benchmarks are for public and private use in establishing a point in space. Note: The benchmarks are referenced to the Chicago City Datum = 0.00, (CCD = 579.88 feet above mean tide New York). The City of Chicago Department of Water Management’s (DWM) Topographic Benchmark is the source of the benchmark information contained in this online database. The information contained in the index card system was compiled by scanning the original cards, then transcribing some of this information to prepare a table and map. Over time, the DWM will contract services to field verify the data and update the index card system and this online database.This dataset was last updated September 2011. Coordinates are estimated. To view map, go to https://data.cityofchicago.org/Buildings/Elevation-Benchmarks-Map/kmt9-pg57 or for PDF map, go to http://cityofchicago.org/content/dam/city/depts/water/supp_info/Benchmarks/BMMap.pdf.

The website availability metrics below are derived from an automated monitor that sends a request every two minutes to each website. The website is considered unavailable if the response to any request takes longer than a pre-defined wait time. The monitors run continuously and are not normally disabled during scheduled maintenance or downtime, so the reported metrics incorporate both planned and unplanned downtime.

Districts which have been proposed for landmark designation by the Commission on Chicago Landmarks and remain under consideration are not included. This information is for illustrative purposes only; the legal boundaries are as identified by the respective landmark designation ordinances. A data set containing Individual Chicago Landmarks is available separately. Go to http://j.mp/m7t5nB to access the related GIS layer files.

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. Background Info: Auto Pound Locations (http://j.mp/kG5sgF). Tow Process Overview (http://j.mp/lfBOEP). Common Towing Questions (http://j.mp/imFYlp). Parking and Standing Violations (http://j.mp/ifW8Uj). Data Owner: Chicago Police Department. Time Period: Last 90 days. Frequency: Data is updated daily. Related Applications: Find Your Vehicle (http://j.mp/lWn0S7).

This dataset presents current and former locations of vehicles that have been relocated by the City of Chicago within the last 90 days. Vehicles may be relocated, but not impounded, due to inoperability, accident, severe weather, special events, construction or other work being performed in a thoroughfare where the vehicle was previously located. Data Owner: Streets & Sanitation. Time Period: Last 90 days. Frequency: Data is updated daily. Related Applications: Find Your Vehicle (http://j.mp/iZiX0B).

This dataset contains the current estimated congestion for the 29 traffic regions. For a detailed description, go to: http://bitly.com/TeqrNv. 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.

This dataset contains the current estimated speed for about 1250 segments covering 300 miles of arterial roads. For a more detailed description, go to: http://bit.ly/Q9AZAD.

When moisture seeps into pavement, it expands when it freezes and contracts when it thaws. This flexing of the pavement, combined with the melted water and the stress of vehicular traffic, causes pavement to deteriorate and potholes to form. The Department of Transportation (CDOT) responds to potholes reported through 311’s Customer Service Requests (CSR) system by mapping open pothole requests each morning and routing crews in geographic clusters so as to fill as many potholes as possible per day. This metric tracks the average number of days CDOT takes to complete pothole repairs per week. Total number of requests fulfilled per week is also available by mousing over columns. The target response time for pothole repairs is within 7 days. For more information about pothole repairs, see CDOT’s pothole Frequently Asked Questions page: http://www.cityofchicago.org/content/dam/city/depts/cdot/PotholeFAQ_winter1011.pdf
