This document discusses Alternative 2 for flood protection as presented by the Santa Clara Valley Water District and raises concerns about how it was illustrated. It notes that Alternative 2 would involve constructing flood walls for 1% flood protection and estimates that around 5 acres of oak woodlands could be at risk if trees within 25 feet of the walls are impacted. The document advocates for using underground diversion alternatives instead of flood walls to protect the area in order to save the oak trees. It provides examples of potential overflow diversion routes under roads that could achieve flood protection without using walls.
