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.

Basic Parcel Information Report With Use

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. A separate Development Log table includes general project information, such as development status and statistics related to the entire project.

The MapLot Table provides location information used by the Cambridge Assessing Department for all developments found in the last published edition of the Log, whose status range from In Permitting to Complete in the current calendar year, as well as any completed since 2011.

Description
This data set derives from several sources. The primary source is a data dump from the VISION assessing data system, which provided data up to date as of January 1, 2012, and is supplemented by information from subsequent building permits and Development Logs. (Use codes provided by this system combine aspects of land use, tax status, and condominium status. In an effort to clarify land use type the data has been cleaned and subdivided to break the original use code into several different fields.) The data set has further been supplemented and updated with development information provided by building permits issued by the Inspectional Services Department and from data found in the Development Log publication. Information from these sources is added to the data set periodically. Land use status is up to date as of the Last Modified date.

Differences From “Official” Parcel Layer

The Cambridge GIS system maintains a separate layer of land parcels reflecting up to date subdivision and ownership. The parcel data associated with the Land Use Data set differs from the “official” parcel layer in a number of cases. For that reason this separate parcel layer is provided to work with land use data in a GIS environment. See the Assessing Department’s Parcel layer for the most up-to-date land parcel boundaries.
