Wayland Patch 2/15/11: Residents, DPW Talk the Future of Hannah Williams Park. The Department of Public Works and citizens from throughout Wayland have begun discussions regarding the future of the Hannah Williams Playground on Main Street. In recent years, the play equipment at the park has drawn concerns that the aging wood can lead to splinters and that the chemicals used to treat that wooden playground equipment, popular when the structure was constructed years ago, are, in fact, not particularly healthy for children. Don Oullette, DPW director, has been gathering information for reconfiguring the park and presented a few options to citizens during a meeting late last week.
