Abstract: This portion of the overall D4 program strives to integrate geomorphic analysis and aquatic ecology principles to increase in-stream complexity in 8 of the urbanized waterways in Santa Clara Valley: Stevens Creek, Los Gatos Creek, Guadalupe Creek, Alamitos Creek, Guadalupe River, Upper Penitencia Creek, Coyote Creek and Uvas Creek. Major tributaries believed to support anadromy are also considered including Pheasant and Hicks, on Guadalupe Creek, Arroyo Aguague on Upper Penitencia Creek, and Little Arthur Creek and Bodfish Creek on Uvas Creek. The eight priority SC-CCCST [South-central and central California coast steelhead trout] streams selected by the District, based on the literature and input from various resource agencies. In a future second phase of work, the District plans to apply this Program to the remaining SC-CCCST streams. Table of contents: 1. Introduction -- 2. Physical setting -- 3.
