Average Daily Traffic Counts 1972 to 2017 (Historical)

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.
ASSESSING_ParcelsFY2016

NEW MAP: https://data.cambridgema.gov/Assessing/Cambridge-Parcel-Data-Map/nz6r-3fde This dataset is OBSOLETE as of 10/24/2024 and will be removed from the Open Data Portal on 10/24/2025 An updated version of this dataset is available at https://data.cambridgema.gov/Assessing/Cambridge-Parcel-Data/c392-hjk3/about_data 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. For more information and download links see: https://www.cambridgema.gov/GIS/gisdatadictionary/Assessing
Article 22 Green Building Review Projects

Profiles of development projects that are subject to Section 22.20 – Green Building Requirements of the Zoning Ordinance. Green Building Requirements ensures that major new projects and substantially rehabilitated buildings are planned, designed and constructed using environmentally sustainable and energy-efficient practices. The green building ordinance uses sustainable building rating systems such as LEED, Phius, PHI and Enterprise Green Communities as technical frameworks to ensure that buildings throughout the City achieve a higher level in building energy use and efficiency, sustainability, and resiliency. Certification by the rating agency is NOT required, but project developers must provide documentation and signed affidavits from a Green Building Professional that confirm that the standards are being met.
American Community Survey 5-Year Estimates by Neighborhood: Socio-Economic Characteristics

This dataset provides socio-economic information for Cambridge neighborhoods, based on 2020-2024 American Community Survey estimates. Because the U.S. Census Bureau does not publish data at the geographic level of Cambridge neighborhoods, 2020 Census block groups were aggregated to approximate neighborhood boundaries. In most cases, block group boundaries align closely with neighborhood boundaries; however, there are notable discrepancies - especially in neighborhoods 10 (West Cambridge), 12 (Cambridge Highlands), and 13 (Strawberry Hill). For these neighborhoods in particular, the geographic boundary differences are significant, so interpret the aggregated data with extra caution.
American Community Survey 5-Year Estimates by Neighborhood: Median Income

This dataset provides median income information for Cambridge neighborhoods, based on 2020-2024 American Community Survey estimates. Because the U.S. Census Bureau does not publish data at the geographic level of Cambridge neighborhoods, 2020 Census block groups were aggregated to approximate neighborhood boundaries. Block group-level household and family income distributions were aggregated to generate neighborhood-level distributions. Median incomes for each neighborhood were then estimated from the neighborhood-level distributions. All amounts are reported in 2024 dollars. In most cases, block group boundaries align closely with neighborhood boundaries; however, there are notable discrepancies - especially in neighborhoods 10 (West Cambridge), 12 (Cambridge Highlands), and 13 (Strawberry Hill). For these neighborhoods in particular, the geographic boundary differences are significant, so interpret the aggregated data with extra caution.
American Community Survey 5-Year Estimates by Neighborhood: Housing Statistics

This dataset provides housing information for Cambridge neighborhoods, based on 2020-2024 American Community Survey estimates. Because the U.S. Census Bureau does not publish data at the geographic level of Cambridge neighborhoods, 2020 Census block groups were aggregated to approximate neighborhood boundaries. In most cases, block group boundaries align closely with neighborhood boundaries; however, there are notable discrepancies - especially in neighborhoods 10 (West Cambridge), 12 (Cambridge Highlands), and 13 (Strawberry Hill). For these neighborhoods in particular, the geographic boundary differences are significant, so interpret the aggregated data with extra caution.
American Community Survey 5-Year Estimates by Neighborhood: Basic Demographics

This dataset provides basic demographic information for Cambridge neighborhoods, based on 2020-2024 American Community Survey estimates. Because the U.S. Census Bureau does not publish data at the geographic level of Cambridge neighborhoods, 2020 Census block groups were aggregated to approximate neighborhood boundaries. In most cases, block group boundaries align closely with neighborhood boundaries; however, there are notable discrepancies - especially in neighborhoods 10 (West Cambridge), 12 (Cambridge Highlands), and 13 (Strawberry Hill). For these neighborhoods in particular, the geographic boundary differences are significant, so interpret the aggregated data with extra caution.
Tree Removal Permits

This dataset shows issued tree removal permits in Cambridge. For any Significant Tree removal, a permit is required from the City Arborist and subject to rules and regulations under City of Cambridge’s Tree Protection Ordinance, Title 8, Chapter 8.66, of the City’s Municipal Code. A Significant Tree is defined as any tree that has a diameter equal to or greater than six inches (6”) measured at breast height (4.5 feet above the ground). A Mitigation Payment will be required for all Significant Trees removed where an insufficient quantity of Replacement Trees is provided.

Traffic Speed Studies (Historical)

The Traffic, Parking &Transportation department has conducted over 600 speed studies since 1987. Some locations have been studied more than once. The speed of each passing vehicle is recorded by radar for an hour each in the morning rush hour, evening rush hour, and midday. From these results, we find the 85th percentile speed for each one-hour period. The 85th percentile speed describes a speed that 85% of drivers are traveling slower than (and 15% of people are driving faster than). Traffic engineers use 85th percentile speed for most traffic safety analyses and design standards. In this dataset, the speed reported is the highest 85th percentile speed for all three one-hour periods studied.
TRAFFIC_MeteredParkingSpaces

This polygon layer contains metered street parking spaces in the City of Cambridge. Created for use with online permitting for street obstructions (moving vans, dumpsters, etc.) and for the Traffic and Parking Department for parking meter inventory. For more information and download links see: http://www.cambridgema.gov/gis/gisdatadictionary/traffic/traffic_meteredparkingspaces.aspx
Stormwater Permits

Stormwater Permits since May 2019. Stormwater runoff is generated when precipitation from rain and snowmelt flows over land and does not soak into the ground. As runoff flows over impervious surfaces (paved streets, parking lots, and building rooftops), it accumulates debris, oil, pet waste, chemicals, sediment or other pollutants that could adversely affect the quality of nearby waterways if untreated. Stormwater management is a combination of engineering, construction, site maintenance and public outreach efforts to address runoff quality and quantity. Structural controls such as pipes, catch basins, and grit chambers are used to control both the quantity and rate of stormwater runoff and the quality of stormwater discharged to water bodies. Non-structural controls such as water quality monitoring, vegetative swales, public education, and policies relative to pest management, fertilization and construction erosion control are also important.
