Non-emergency service requests submitted through Cambridge's Commonwealth Connect application powered by SeeClickFix Open311.

Please note that the City of Cambridge uses Commonwealth Connect to track both public and internal work orders. Occasionally, a ticket will change from internal to public, or vice-versa. All tickets that originated as public requests are included in this dataset. However, technical constraints prevent us from displaying information for tickets that originated as internal work orders.

Prior to using Commonwealth Connect, the City utilized iReport. Three open datasets derive from historical iReport data:
-Pothole Repair Requests (https://data.cambridgema.gov/Public-Works/Pothole-Repair-Requests/h2y4-rf5c)
-Graffiti Cleanup Requests (https://data.cambridgema.gov/Public-Works/Graffiti-Clean-Up-Requests/hk2d-8z9b)
-Unshoveled/Icy Sidewalk Complaints (https://data.cambridgema.gov/Public-Works/Unshoveled-Icy-Sidewalk-Complaints/72bt-ct3c)
-Snow/Ice Sidewalk Ordinance Violations (https://data.cambridgema.gov/Public-Works/Snow-Ice-Sidewalk-Ordinance-Violations/q8b2-58ab)

The Development Log provides a record of large-scale development projects occurring in the City of Cambridge. The Log, updated on a quarterly basis, is distributed to City departments and the public to keep them posted about development progress, from permitting through construction to completion. This map includes all projects listed in the current edition of the Log, whose status range from In Permitting to Complete in the current calendar year.

Since a project may include more than one use, data on each specific use found within a project is found in the associated Development Log Project Use table.

List of crashes involving motor vehicles, bicycles and/or pedestrians reported in the City of Cambridge over the last 4 years (2010-2013). Please Note: addresses are approximate.

This dataset contains the Average Daily Traffic counts and AM and PM peak hour Traffic counts measured on various road segments in the City of Cambridge from 1972 to 2017. The counts in this data set reflect only vehicle counts. An Average Daily Count measures the number of vehicles for an entire day, or an average of several days. Automatic Traffic Recorders (ATRs) log every vehicle that passes in each direction and this data is used to calculate Average Daily Traffic volumes and AM and PM Peak Hour Traffic Volumes for the street. The Peak Hour is average highest number of vehicles recorded during the morning and evening peak hour. Not all streets have the same peak hour. For example, the peak hour for one street could be 5 pm to 6 pm, whereas a peak hour for another street could be from 5:15 pm to 6:15 pm. The peak hour for a street can also change from day to day. When counts are done for several days, the Peak Hour count is the average of the highest peak hour over those days.
Automatic Traffic Recorders (ATR’s) are rubber hoses temporarily affixed to the street. When a vehicle passes, a pulse of air passes through the hose and triggers an air switch in a recording device on the roadside. The recorder device is a small steel box powered by a battery. Air switch triggers are stored on board and later downloaded to a computer. Note: Traditional and older ATRs were not able to record bicycles, however, more recent ATR’s (past 5 to 10 years) have been able to record bicycles that pass over the recorder.

Fire Hydrants are maintained by the Engineering group at the Cambridge Water Department, Hydrants are also monitored by Cambridge Fire Department. Used for public safety, mapping, and water distribution.

This polygon layer contains all of the property parcels in Cambridge. Each parcel has a unique Map and Lot ID number that links it to a record in the Assessing Department's Vision database system.
Created for internal use by the Assessing Department to provide a visual reference associated with each parcel in the CAMA database. Created for interdepartmental and external use as part of the web viewers on the City's website. Also created for addressing/geocoding needs, although the Buildings and Master Address List are currently more accurate than Parcels. NOTE: The Parcels GIS data layer is NOT used by Assessing to calculate land area or taxes. Assessors refer to actual deeds or plans accepted by the Massachusetts Land Court. The figures stored in the GIS data layer are for general reference purposes only.

The Medical Events data set reflects information approved for general release by the Cambridge Police Department and the Cambridge Fire Department. All entries are inputted by dispatchers in the Emergency Communications Center (ECC). This data set does not reflect all events received by the ECC. Certain entries are not included due to concerns related to privacy, criminal investigation, or protected data. Additionally, not all entries reflect a dispatched response and some data may reflect a duplicate entry for a specific incident.

The decision for a medical incident to be coded as one of the three types is not a reflection of the importance of the call, and should not be misconstrued to mean that the dispatcher or Cambridge ECD feels that the call or caller are unimportant. We strive to provide the best possible emergency service to our constituents, and never withhold care due to classification. Within each Chief Complaint, there are rankings of severity and priority; for privacy and security reasons, we do not provide this information, but this internal ranking is often as important to the dispatcher as the category. All calls received at the Cambridge ECC are treated with the utmost care and respect.

Violations cited (105 CMR 410.000) when inspected by Housing Inspector. This map is created from a filtered view of the main Housing Violation dataset that shows only the 410.55 - Extermination of Insects, Rodents and Skunks Violations.

A demonstration map of open data crashes involving motor vehicles, bicycles and/or pedestrians reported in the City of Cambridge from January 2015 through December 2016.

PLEASE NOTE: Geocoding imperfections in this dataset could result in illusory crash "hotspots" appearing on the map. This map is simply meant to be a demonstration of how the open data portal can be used to visualize geospatial trends.

Any data or text that may identify specific persons or companies has been omitted. Please see attached MassTRAC documentation for additional explanation about crash reporting data elements.

Note: crashes involving pedestrians are indicated in the “P1 Non Motorist Desc” and “P2 Mon Motorist Desc” columns. When using Socrata's built in visualization tools to map crashes, please use the geocoded "Location" column. The column "May involve cyclist" specifies whether a given incident may involve a bicycle operator.

This data set contains all of the sighted locations of public art in the City. Data Set contains the name of the artist, title of the work, location, year, site location name, interior/exterior location, and coordinates for the location of the art work.
