9.51 Major Flooding...If Saratoga Creek has substantial flows, overbanking will occur on the east bank between US-101 and Scott Blvd, bounded by the creek and San Tomas Expwy, inundating the office park.
9.5 Major Flooding: San Tomas Expwy flooded, with water moving northward under the I-280 viaduct towards Homestead. Water sheet flows along roads towards Pruneridge Golf Course. Extensive flooding stemming from the daylighted culvert upstream of Homestead Rd. Areas east of Kiely Blvd and west of Scott Blvd are at risk. Floodwaters may continue to move northward, bounded by San Tomas and Scott Blvd, crossing the Caltraintracks toward US-101...
9 Moderate Flooding: Spills upstream of Williams Road move toward the west and move northward along Boynton Ave, ponding along I-280. Worst flooding east of Boynton High School. Overbanking upstream of Homestead Rd spread along San Tomas Expwy moves northward and spreads into surrounding neighborhoods. If Saratoga Creek has substantial flows as well, overbanking on the east bank is possible between US-101 and Scott Blvd.
8 Minor Flooding: Overbanking possible near Williams Road, Payne Ave, West Hamilton Ave, and Campbell Ave, causing street flooding. Possible overbanking onto San Tomas Expwy between Homestead Rd and Forbes Ave, where the underground culvert daylights for a short stretch.
