For three months this fall, a 24,000 square-foot vacant lot at the intersection of Mandela Parkway, West Grand Avenue and Peralta Street in West Oakland will be transformed into a creative community space filled with art and commerce. Each weekend from October 4 to December 15, the Peralta Junction Project will harness the strong local presence of the industrial arts and artists to create rich social and economic opportunities for an often-challenged neighborhood.
