Flood Damage Potential
If you want to know where your property is situated in the floodplain contact the City Building Department at 656- 4690. Reference materials are also available at the Santa Clara Public Library. In the event of a potential flood, Santa Clara will notify Residents and Businesses through a mass communication Parlant technology service. The sign up for our community alert system can be found on our City website under “Community Alert“.
Portions of the City of Santa Clara can experience significant damage during major flooding events as evidenced by the floods of January, 2005 and December, 2010. The Santa Clara River and Sand Hollow Wash have potential to become major flood hazards during or after heavy rain storms. Both tributaries appear small but have large drainage basins and can produce large flood flow events.
According to the 2009 FEMA Flood Insurance Study, the 100 year flood event in the Santa Clara River is projected to be 8,200 CFS; and 6,600 CFS in the Sand Hollow Wash. Other tributaries within the City include the Tuachan Wash and Lava Flow Wash.
Although many hillsides within the City are located outside of the floodplain, they also pose a flood threat to the properties located below them.
Hillside floods occur frequently and often deposit debris.
The flood hazard areas of the city are subject to periodic inundation of flood waters which could result in loss of life and property, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety and general welfare.
Flood losses can be caused by the cumulative effect of obstruction in areas of special flood hazards which increase flood heights and velocities, and when inadequately anchored, damage uses in other areas. Structures that are inadequately, elevated or otherwise protected from flood damage also contribute to the flood loss.
Help Protect Natural Floodplain Functions
Floodplains are defined as areas of low-lying ground adjacent to a rivers, ponds, lakes, and oceans that are formed mainly of river sediments and are subject to flooding. Floodplains provide a wide range of benefits to both human and natural systems. They serve important functions in protecting the physical, biological, and chemical integrity of water.
The riparian tree canopy along the Santa Clara River facilitates transpiration, provides shade, and maintains habitat for deer, ducks, geese and other creatures. Natural stream meanders also create a slower water movement thereby lessening erosion and providing better filtration than man-made concrete waterways. A Master Plan Document has been prepared to assist property owners in restoring the riparian corridors along the river.

Santa Clara City has strict regulations prohibiting dumping any material or harmful substance in a stream channel, ditch, storm drain, or street gutter system which regularly or periodically carries surface water. This includes brush, fill, and other debris that will raise flood and storm water levels in the City’s drainage system. This material also includes chemicals, oil, and other substances that are harmful to water quality, surface water and ground water quality. Residents need to be aware that it is against the City Storm Water Ordinance [Chapter 13:24] to sweep or blow leaves and grass clip-pings into the street, curb and gutter or sidewalk. Residents are also responsible to retain any dirt, top soil or rock, etc. onto their property.
The City is committed to protect our water quality. Your help is needed to help protect this valuable resource. Together we do make a difference.
To report spills, dumping emergencies, violations or suspicious activities please call (435)-673-6712, the main City phone number and after hours number, or call the Dixie Clean Storm Water Coalition HOT LINE at (435) 634-5730. Generally an investigator will respond and in most cases visit the problem site.
Although no one can prevent natural disasters from occurring, there are many things you can do to make the impact less devastating for your family. Every home should have 3 key elements in place before a disaster strikes:
- Evacuation Plan
- Communication Plan
- Emergency Supply Kit

There are a number of techniques you can implement that can protect your property from flood damage. Retrofitting, re-grading, correcting drainage problems are common examples of preventative measures. Another approach is to make walls waterproof and place water-tight closures over doorways. This is effective in areas with very shallow flooding. The Public Library and the City Building Department have more information on retrofitting and flood-proofing.

Flood Plain Development
Development in a regulatory floodplain requires a Floodplain Development Permit. Always check with the Building Department at 656-4690 before you build, fill, alter, or grade your property to find out what permits are required. In some cases, State and Federal permits may also be required.
The City has also designated Erosion Hazard Zones within the City which require additional engineering studies and erosion protection improvements to be completed prior to development.
If you don’t have flood insurance, talk to your insurance agent. Homeowner’s insurance policies DO NOT cover damage from floods. However, because Santa Clara City participates in the National Flood Insurance Program, you can purchase a separate flood insurance policy. This insurance is backed by the Federal government and is available to everyone, even for properties that have been flooded. Some people have purchased flood insurance because it was a condition required by the bank to obtain a mortgage or home improvement loan. Usually these policies cover only the building’s structure and NOT the contents. Floods often cause more damage to furnishings and contents than to structures. If you have flood insurance, check the amount and consider purchasing contents coverage. Contact your insurance agent for more information about flood insurance.

Flood Safety Tips
Do not walk through flowing water. Drowning is the number one cause of flood deaths, mostly during flash floods. Currents can be deceptive; six inches of moving water can knock you off your feet.
Do not drive through a flooded area. More people drown in their cars than anywhere else. Do not drive around road barriers; the road or bridge may be washed out.
Stay away from power lines and electrical wires. The number two flood killer after drowning is electrocution. Electrical current can travel through water. Report downed power lines to the City Public Services Department at 656-4690.
Some appliances, such as televisions, keep electrical charges even after they have been unplugged. Don’t use appliances or motors that have gotten wet unless they have been taken apart, cleaned, and dried.
Look before you step. After a flood, the ground and floors are covered with debris including broken bottles and nails. Floors and stairs that have been covered with mud can be very slippery.
Be alert for gas leaks. Use a flashlight to inspect damage. Don’t smoke or use candles, lanterns, or open flames unless you know the gas has been turned off and the area has been ventilated.
Contact Questar Gas at 800-541-2824 for emergency service.
Sewers may surcharge during flooding and in extreme cases, back-flow into basements. Be aware of your home sewer clean-out locations, pumps and operation controls.
All new and substantially improved development in the flood plain is required to have an Elevation Certificate completed by a Registered Professional Engineer or Surveyor. Elevation Certificates are kept on file for public inspection at the City Building Department located at 2603 Santa Clara Drive.
