| Impacts - E19 Information | |
| 10.0 Feet | SCVWD may choose to deploy flood abatement measures at the I-280 underpass to protect downtown San Jose. |
| 13.0 Feet | Guadalup River begins to flood upstream of West Alma Avenue on right (east) bank side near the Elks Lodge. At higher stages, the Alma Avenue underpass beneath CA-87 and the Belmont Avenue neighborhood will likely flood. Ross Creek begins to flood near Jarvis and Cherry Avenues when stage reaches this value on the Guadalupe. At slightly higher stages, Ross Creek will continue to flood northward along surface streets, possibly reaching north of Capitol Expressway/Hillsdale Avenue. Canoas Creek may experience break-out near Nightingale Drive spreading both northward and southward along surface streets. At higher stages, the neighborhood south of Canos Creek at the confluence with the Guadalupe River will be inundated. |
| 17.0 Feet | Flow begins to leave the channel on the right (east) b ank side approximately 500 feet upstream of Branham Lane, at Harvest Meadow Court, upstream of the Capitol Expressway, and between Alma and Willow Streeet along Lelong Street. Flooding between Alma and Willow flow northward, inundating Willow Street underpass. Break-out locations along the left (west) bank include the Minnesota Avenue neighborhood upstream of CA-87. Flooding from Ross Creek will continue northward up to Curtner Avenue along surface streets. Flooding from Canos Creek will continue northward inundating local surface streets and the neighborhood north of Wren Drive at the confluence. |
| 18.7 Feet | Widespread flooding within the Guadalupe River/Ross Creek/Canos Creek confluence area and locations north and south. Inundated areas include the I-280/CA-87 interchange, the CA-87 Lelong Street onramp, Willow and Alma Street underpass, and the Washington-Guadalupe, Tamien, and Alma-Almaden neighborhoods and Washington Elementary school area. On the river's west side flooding is expected north of Alma Avenue and south of Willow Street, and streamward of Prevost Street. Inundation upstream of Branham Lane at the Cherry Avenue/Almaden Expressway shopping center on the river's west side with flows then escaping north along surface streets on the east side. The western edge of the Pinehurst neighborhood will undergo street flooding that will flow northward towards Hillsdale Avenue. Overbanking will occur upstream of Capitol Expressway/Hillsdale Avenue on the right bank, traveling east along the Capitol Expressway before flowing north along Foxworthy Avenue into the Farm Drive neighborhood and eventually ponding along Canoas Creek levee. Ross Creek continues to flood northwards along surface streets until reaching the I-280/CA-87 interchange. Canoas Creek continues to flood northwards into the Mill Pond neighborhood, inundating areas between CA-87 and Almaden Expressway, and eventually joining existing Guadalupe flood waters between CA-87 and the Guadalupe River. |
