The Watertown Department of Community Development and Planning is holding community meetings to discuss Arsenal Park and the potential for design/redesign of some areas within the park. Anyone interested in learning more about Arsenal Park and in sharing ideas about how the park should be designed and used is encouraged to participate in the process. Of particular interest is the design of the eastern section of the park which includes the existing courts and open space adjacent to the Arsenal Yards and connectivity into and through the park.
