San Francisco used to be covered with creeks and streams, but now only a few remain. Most of the waterways are long gone, having been built over or blocked as the city developed. But for a few days in April, the former Hayes Creek will reappear in an artistic new way. The creek used to travel through Hayes Valley and near City Hall during the wetter months of the year and then disappear during the dry season. Wet season waterways like Hayes Creek were known as arroyos. Next year, its path will be retraced in either paint or light between Seventh and Ninth streets as part of the Market Street Prototyping Festival.
The creek will rendered on the city's sidewalks for the festival's duration as part of a project known as "Ghost Arroyos." Visitors will be able to trace the path of the disappeared arroyos while listening to a recording of "hydrological soundscapes and oral histories." The festival lasts only three days, though, so the reappearance of the creeks will be even more fleeting than their original existence.
