As Chairman of the Blackstone Boulevard Park Committee, Principal Colgate Searle has been tasked with creating an inventory and maintenance manual addressing issues of sustainability as the park begins to change in the face of global warming. Blackstone Boulevard was originally designed as a corridor for streetcars connecting to the Swan Point Garden Cemetery, and is now a popular route for joggers and dog-walkers. SDG has been working to inventory and map all tree species and their conditions as well as identify areas for improvement pertaining to erosion and drainage on the paths. Part of the proposal for the park's future is to expand the boundaries to include the street trees on either side, creating a complete segment of urban forest. Colgate recently presented the park's fascinating geologic history (see below) to the members of the Blackstone Parks Conservancy.
