The first inhabitants of the Sausal Creek watershed were the Huchiun or Yrgin
tribelets of the
Ohlone people. They harvested acorns, buckeyes and other foodstuffs at a time when enormous live oaks, alders, willows, and big-leaf maples grew on the creek's banks in what is now
downtown Oakland, California. Also, large
Coast redwoods (
Sequoia sempervirens) grew on the ridge where Skyline Boulevard now runs. Sausal Creek was named
Arroyo del Bosque by
Father Juan Crespí during the
Pedro Fages Expedition in 1772. Later the Sausal watershed became part of the
Rancho San Antonio land grant to Sergeant Luis Maria Peralta in 1820. By 1841 Peralta's descendants were selling the giant redwoods and by 1850 there were at least ten sawmills operating in the watershed. The Blossom Rock Tree had a trunk diameter of 33.5 feet and was over 300 feet tall. It was so named because sailors used it as a navigational aid to avoid an underwater hazardous rock,
Blossom Rock, in San Francisco Bay. The creek was also known as
Fruitvale Creek, when the settlement of
Fruitvale was established in 1856 when Quaker nurseryman
Henderson Luelling, planted hundreds of cherry trees along Sausal Creek, and named the area "Fruit Vale". As Oakland grew larger, the Sausal Creek watershed was significantly altered. When people built their houses next to Sausal Creek, they often planted gardens, which brought in plants from around the globe. Over time, since many of these plants were foreign, they were not adapted to the environment, and they could not be controlled. In 1935, the Works Progress Administration began work deep in the canyon. Initially they were funded to clear landslides and build fire trails. In 1937, the WPA constructed a sanitary sewer that runs adjacent to Sausal Creek under the creek-side trail that runs from Dimond Park to slightly beyond the Leimert Bridge. In 1939 and 1940, further work was done to channelize the creek in concrete and stabilize its banks. The creek still ran, but at a quickening pace. What had once been a slow, babbling brook was now a torrential storm. Culverts soon covered the creek. In the 1980s, behind the Cohen-Bray House, on 29th Avenue near International Boulevard, preservationists fought over a culvert project that preservationists thought would deal a blow to a neighborhood rife with drugs and crime. ==Restoration projects==
