Powers Childcare Center Richmond, California This new childcare center replaces a WWII-era building and will accommodate 200 preschoolers. The play yard celebrates a nautical theme with a sandbox in the shape of a ship's hull, an embedded compass rose of colored concrete, a cargo net, an undulating wall simulating tidal action, and a working hand pump that moves water from the ship into the sand area. Images of sea creatures are embedded into the concrete.
