ESA’s 1975 Environmental Impact Report on Christo’s Running Fence was featured in the Smithsonian’s exhibition of Christo and Jeanne-Claude: Remembering the Running Fence, a definitive record of the Running Fence, Sonoma and Marin Counties, California, 1972-76, a major early work of art by the world-renowned artists Christo and Jeanne-Claude. The work of art, a 24 1/2-mile long, 18-foot high fabric fence, lasted for 2 weeks and stretched from Petaluma, California through the town of Valley Ford and, finally, into the Pacific Ocean at the northern tip of Marin County. ESA’s EIR was the first environmental impact report created for a work of art. The exhibition ran from April 1-September 26, 2010.
