Such wide, graveled banks are a classic feature of sycamore alluvial woodland, and they're integral to the tree's health and longevity. A distinct and vital ecosystem in California, sycamore alluvial woodland is characterized by summer-dry streambeds that branch and braid out through the sandbars, silt, and gravel beds deposited by winter rains and floods. [...]. Livermoore's Sycamore Grove Park is among the few preserved alluvial woodlands left in the East Bay, and as such it provides us a window into an older California.
The flooding that occurred during the 2016/2017 winter rains hopefully boosted the revival and healthy growth of those sycamores that had been damaged in drought years.
Sycamore Grove Park has two main entrances (a few miles south from downtown Livermore): the Wetmore Road entrance at the park's northwest end and the Arroyo Road entrance at the southeast side, not very far from the Del Valle Regional Park entrance.

To get to the Arroyo entrance, drive south on S L Street from downtown Livermore. S L Street continues as Arroyo Road. After passing the Arroyo Road/Wetmore Road junction with the historic Olivina Gate, follow Arroyo Road for another 1.5 miles and find the park entrance and ranger station to your right across the Wente Vineyards.
