15.51 Cont'...Areas along Thousand Oaks Park and near Capitol Expressway at risk of overbanking. If flood is sustained or increasing, car dealerships along Capitol Expressway are inundated. The Thousand Oaks Neighborhood experiences significant street flooding and overtopping occurs near Branham Lan as well as flooding of businesses and the Erikson Neighborhood. Potential flooding on Ross and Canoas Creeks due to high backwater caused by Guadalupe River.

Widespread flooding in the eastern Willow Glen Neighborhood, as well as the Gardner and Atlanta/Bird Neighborhoods. CA87/I-280 interchange at risk from overland flow spilling onto the roadway. Possible overtopping of Guadalupe River between Branham and Capitol, mainly on the east side, with water flowing through streets.
14 Major Flood Stage. Flooding continues to spill near Alam Avenue, flowing northward and crossing east under Willow Street and Alma Avenue viaducts, continuing to flow north. Overbanking occurs at Atlanta Avenue just upstream of CA87. The Willow Glen Neighborhood bounded by Willow Street and Minnesota Avenue see overland flooding.
