Alameda Creek and the 1955 flood
In December 1955, Alameda Creek rose about 20 feet at Niles after three days of rain and overflowed, and more than 300 mostly new ranch homes stood in four to five feet of water. It was the creek's last major flood. The Alameda Flood Control Channel, built in the 1950s and 1960s, now keeps the creek from flooding Niles, Fremont and Union City.
Mud, cleaning and drying
Shovels and wet vacuums remove mud first, because it holds moisture against floors and walls. Surfaces are then washed and treated, and the structure is dried with air movers and dehumidifiers.
- Mud removed before extraction ends
- Surfaces cleaned and treated
- Air scrubbing during removal

Is flood cleanup different from a leak cleanup?
Yes. Floodwater is contaminated by mud and bacteria, so porous materials are removed and surfaces are cleaned and treated instead of simply dried.
When did Alameda Creek last flood Niles?
The last major flood was in December 1955, when the creek rose about 20 feet at Niles. The flood control channel followed.
What happened to people during the 1955 flood?
Evacuees went to an emergency center at Washington Union High School in Centerville, and the nearby Alvarado area flooded too.
Can furniture be saved after a flood?
Solid wood and some hard goods can be cleaned and dried. Upholstered pieces, mattresses and particleboard that sat in floodwater are usually discarded.
Does a flash flood always need a crawl space check?
If a home has a raised floor, yes, since mud and water collect below. The crew checks and dries that area as part of the job.
Will insurance pay for flood cleanup?
Flood is often a separate coverage from standard homeowner policies, so ask the insurer early and keep photos of the water line.
