River Wilderness Park: Arroyos Development is the creation of two functioning arroyos to re-establish degraded historical ephemeral streambeds. The drainages are located within two sub-watersheds on the River Wilderness Park (RWP) site and above the San Gabriel River. RWP is located within the steep-sided San Gabriel Canyon, at the gateway to the newly established San Gabriel Mountains National Monument. Due to the topography and local weather of the canyon, runoff here can be extreme, but also life-giving to native flora and fauna. The flows from the San Gabriel watershed also supports a majority of the potable water needs of San Gabriel Valley residents, infiltrated through the mountains, river, and spreading basins. This proposed project will reshape and vegetate the arroyos and adjacent landscape to be both functional and to showcase the power of natural systems: to effectively manage, capture, and conserve water as a precious resource, to nourish our communities and habitat, and to celebrate this diverse wildland interface.
