Context:
A heavy winter storm in the fall of 1962 caused significant flooding along Temescal Creek where it crossed San Pablo Avenue. As a result, Alameda County agreed in 1963 to provide flood protection to the cities of Oakland and Emeryville, and the Alameda County Flood Control and Water Conservation District began drawing up plans to contain Temescal Creek, where it flowed through the flatlands, in an underground culvert. Significant culverting from Lake Temescal to Hardy Street was completed in the late 1960s as part of the Grove-Shafter Freeway (Highway 24) project. In the 1970s, two stretches in the flatlands were culverted: from Hardy Street to Telegraph Avenue, and from Adeline to San Pablo Avenue. The middle section, from Martin Luther King Jr. Way to Adeline, was completed in the 1980s. Today, virtually the entire creek, from Lake Temescal to the bay, has been buried.
