Wards and Precincts

See full metadata: https://www.cambridgema.gov/GIS/gisdatadictionary/Elections/ELECTIONS_WardsPrecincts Description This polygon layer contains 11 wards and 33 precincts within the City of Cambridge. These were adjusted in 2021 from the 2020 U.S. Census. The Massachusetts Legislative boundaries do not follow these Cambridge Ward and Precinct boundaries in several areas. In part, this was because of the compressed timeline due to the Covid-19 pandemic during the 2020 US Census. Municipalities and the State were unable to coordinate precincts and legislative districts, and as a result sub-precincts within 9 precincts were unavoidable. Voters in a sub-precinct are listed on a separate voting list and have different ballots from other voters in the precinct during State Elections. Purpose This layer was created for general use by the Cambridge Election Commission and for public distribution. Cambridge wards and precincts which designate where voters will vote.

Resident and Visitor Parking Permits

This dataset contains a list of both Residential Parking Permits and Visitor Parking Permits. The Traffic, Parking and Transportation Department’s Permit Year spans from November 1st through October 31st of the following year. The Parking Permit renewal period spans from November 1st through January 31st of the following year. This dataset will be updated semi-annually at the end of the Permit Year, and at the end of the Parking Permit renewal period, to provide users with updated information from before and after permit renewals occur. The dataset identifies the Census Block that each parking permit is located in. The first person that applies for a Resident Parking Permit will automatically receive that household’s single Visitor Parking Permit with their Resident Permit. For households without a vehicle or those who only require a Visitor Parking Permit, the associated fee is $25.00, except for Senior Residents (age 65 or older) or persons with disabilities. The Account Number field is associated with the first resident in a household who applied for either a Resident Parking Permit or a Visitor Parking Permit. If the resident applied for a Resident Parking Permit they should have an associated Visitor Parking Permit with the same Account Number. Each permit is characterized by a permit type. The permit types in this dataset include: A1: Standard Cambridge residential parking permit. A2: Replacement residential permit. A3: Senior resident permit. G1: Visitor permit, no resident permit. G2: Visitor permit with Resident Permit. G3: Senior Visitor Permit Only. A Senior Resident could have both an A3 and G3 permit, or just a G3 permit. Resident Parking Permits allow Cambridge residents to park their vehicles, including motorcycles, in locations throughout the City posted "Parking by Permit Only". The purpose of the City's Resident Parking regulation is to maximize the availability of parking for Cambridge residents while discouraging long-term parking on residential streets near commercially zoned areas or transportation access points. Visitor Parking Permits are provided to Cambridge residents for use by their guests to park near the residents’ homes. When placed on the dashboard, it may be used for up to three consecutive days in locations signed as “Parking by Permit Only” in the geographic area shown on the map on the back of the visitor permits or here on the Traffic and Parking Department’s website. http://www.cambridgema.gov/traffic/Permits/visitorparkingpermits/visitorparkingmap
