n ARCHITECTURE 'SUBTILE' WEST SACRAMENTO / LANDSCAPE ARCHITECT: QUADRIGA In May 2015, West Sacramento released a heavily pub- licized request for proposal for a public art installation at the city’s River Walk Park. The city was looking to animate the landscape in a way that would ref lect the historical, cultural and geographic character of the site through art and landscape. After receiving more than 100 proposals from artists around the world, the panel- ists selected "Subtile," a submission from internationally renowned Czech-Argentinian artist Federico Diaz. A very kinetic piece, "Subtile" is meant to suggest a grove of trees whose more than 17,000 ref lective stainless-steel disks are in constant motion with the breeze and echo the chang- ing colors and visual patterns of the clouds, river and surrounding cottonwoods. The artist used a mathemati- cal algorithm to determine the shape and silhouette of the sculpture’s form. Landscape architecture firm Quadriga finalized the site selection and designed the environment surrounding the sculpture. The firm assembled a team of engineers to help with the lighting, footing solutions and permitting, and recommended siting the art piece along the riverfront near a grove of cottonwood trees between The Barn and the Tower Bridge. “The first thing we found was that this piece ref lected the world around it — the vegetation, the skyline, the river — and we wanted to make sure the site would take advantage of views of the mature cottonwood trees, and ref lect both its urban and riparian setting,” says Quadriga principal John Suesens. 46 | May 2019 Because the sculpture is on a protected levee, permits were required from the Central Valley Flood Control Board, the City of West Sacramento, the U.S. Army Corps of Engi- neers and the California Department of Fish and Wildlife. To gain the necessary approvals, the landscape architects provided detailed descriptions of the design, light patterns and improvements and how those might affect potential wildlife species, which added another layer of complex- ity to the design solutions.
