Flood Control

Be Prepared Early

  • Clear debris from drains and stream banks. Remove debris from roadway gutters and storm drains closest to your property. Keep yard debris away from stream banks and out of the stream.
  • Sandbag Information. Consider getting sandbags in advance to protect your home or business from localized flooding. Residents may fill their own sandbags at the self-serve station at Centerville Public Works.  We are no longer providing sandbags at the self-serve station. Contact Centerville Public Works - 801-292-8232. Sandbagging demonstration
  • Monitor weatherMonitor the National Weather Service forecasts and focus on any alerts of flooding. 
  • Monitor streamflow.  Check local stream gauges to help determine the likelihood of flooding. 
  • Report Flooding. Call the Non-Emergency Hotline - 801-298-6000, to report flooding of any kind.

  • Is your property located in a flood-prone area?  Possible flooding is more likely if your home, residence, or business is located within a FEMA regulated 100-yr floodplain (1% Annual Chance Flood) special flood hazard area (SFHA).

Clear Debris

  • Be sure roadway gutters and storm drains closest to your home are clear of any debris. Flood risks increase when drains are clogged with snow or debris.

  • Streamside residents should keep all yard debris away from stream banks and out of the stream. Any debris on or near the banks can easily get swept away when stream levels rise. Once branches, grass clippings, leaf piles, firewood, lumber, and other debris get into the stream, they can block culvert openings, snag on bridge crossings, or quickly clog in-stream trash grates. This can cause flooding, severe bank erosion, and property damage.

  • NRCS Snow Water Equivalent Map
  • Snowpack density has significant implications for the spring melt scenario. Heavy, dense snow holds more water as compared with a light, dry snowpack. Dry snow is light with lots of air pockets. This lower density insulates itself well, which slows down the melt when temperatures start warming up in the spring.
  • There are many other variables that play into the timing of spring runoff, not just the consistency of the snowpack. Cloud cover, sun angle, and air temperature all play a part. Daytime highs and nighttime lows are particularly important. In the ramp-up to runoff, the Watershed Program keeps a close eye on the lows, checking every day to see if overnight lows are below freezing overnight at the 9,000' elevation.
