Oakland's territory covers what was once a mosaic of California coastal terrace prairie, oak woodland, and north coastal scrub.[20] Its land served as a resource when its hillside oak and redwood timber were logged to build San Francisco.[20] The fertile flatland soils helped it become a prolific agricultural region. In the late 1860s, Oakland was selected as the western terminal of the Transcontinental Railroad.[21] Following the 1906 San Francisco earthquake, many San Francisco citizens moved to Oakland, enlarging the population, increasing its housing stock, and improving its infrastructure. It continued to grow in the 20th century with its busy port, shipyards, and a thriving automobile manufacturing industry.
