In 2020, the City of Portsmouth NH acquired a red granite sculpture, Odyssey, by Richard Erdman in VT and installed it as centrepiece of the Prescott Park formal garden fountain in honor of Michael Warhurst who tended the park gardens for 43 years.

"Cod and the Mortal Sea" was created by Terrence Parker under commission from the Portsmouth NH 400th, Inc. The open-sided kiosk in Bohenko Gateway Park on Market Street was transformed by the addition to the Bohenko Gateway Park Sculpture Garden, a joint City and Portsmouth NH 400th, Inc. Legacy Project.
