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.
A Mitigation Payment will not be required if a Significant Tree qualifies for one of the following special circumstances: emergency situation, significant utility infrastructure projects undertaken pursuant to State or Federal regulations or programs, for City park projects, or where a tree poses significant negative impact to an adjacent Structure as defined in 8.66.030, or for dead or dangerous trees, or a Lot is of such density with existing trees that the removal of certain Significant Trees is considered beneficial to the health of the tree canopy on the Lot.
In the event a tree had to be removed due to an emergency situation prior to receiving a permit, an application must be submitted retroactively.
