Once completed, the new U.S. DOT Volpe development will include primarily below-grade vehicular parking and ample bicycle parking. In addition, over 100 new diverse native-species trees will be installed using current best practices in planting, and an extensive landscaping program will be available for the public to enjoy. Even though the federal government is exempt from Cambridge’s local tree ordinance, the tree replacement plan is designed to materially exceed the current local requirements for large projects. To prepare the site for construction, 21 private trees will be removed that are within the building’s footprint or security perimeter. Twenty of those trees are Norway Maples, an invasive species that Massachusetts prohibits from being sold, planted, or propagated. In addition, two street trees will need to be relocated or replaced to accommodate a curb cut required by the project.
