In 2017, Sacramento County received grants from the California Department of Water Resources (DWR) Small Communities Flood Risk Reduction Program (SCFRRP) to complete feasibility studies to reduce flood risk to six Delta Legacy Communities in the north Delta, including: Hood, Courtland, Locke, West Walnut Grove, Ryde, and East Walnut Grove.
East Walnut Grove is located on the east or left bank of the Sacramento River approximately 25
miles south of Sacramento, just south of the Delta Cross Channel (DCC), approximately 1.0 mile
south and downstream of the community of Locke. Levees which protect the tract of land known
as East Walnut Grove are primarily maintained by Reclamation District (RD) 554; and the levees
protecting the industrial, southern portion of East Walnut Grove located on the tract of land
known as Tyler Island are maintained by RD 563.
