Potrero Point

Potrero Point San Francisco is the location of the earliest and most important industrial facilities in the Western United States on the eastern extension of San Francisco's Potrero Hill, a natural land mass extending into San Francisco Bay south of Mission Bay. Potrero Point, the point of Potrero Hill, was systematically blasted and cut, its serpentine cliffs removed. The work yielded two square miles of rock for fill and hundreds of acres of flat industrial land east of Illinois street between 20th Street and Islais Creek.
