Presentation Outline El Nino and Flood Risk Property Preparedness Family Preparedness

What is El Nino? El Niño is a weather phenomenon that involves a warming of the Pacific Ocean west of Peru. The temperature increase can cause dramatic changes in weather patterns worldwide, bringing wet rains to California but drought to Indonesia and Australia.

Change in Jet Stream Delivers More Rain to Southern California L L L

Why is this one such a big deal? This El Niño is as strong as the record 97/98 El Niño Strong El Niños tend to predict wet years

Property Preparedness Tips

Preventable El Nino Rain Impacts: Unprotected slope failures Retaining wall failures from blocked drain holes Collapsed commercial building roofs due to plugged roof drains Fallen trees Localized flooding from blocked drainage courses

Before the Storm Clean gutters and cut down weakened trees that could damage your home. Take care of grading or drainage needs on your property. Check for loose roof tiles or shingles, fix roof leaks. Store outdoor furniture and other objects that could be damaged by storms or thrown by winds. Inspect retaining wall drain holes, surface and subsurface drains and yard drains for signs of obstruction or malfunction. Establish native plants or place other ground cover on bare ground, slopes or freshly graded areas.

Before the Storm – Clear private drainages of obstructions Most flood-prone drainage areas of low-lying property will have a natural water courses that must remain clear of obstruction. Failure to maintain drainage areas can contribute to flooding of adjacent property. Riverside County Unincorporated Community Drainage Task Force Homeowner guidance for watercourse cleaning and slope stabilization; Guidance for removal of structures/walls/debris blocking drainage; Assistance with regulatory permitting; and Drainage junk/debris removal support. (951) 955-2004

Before the Storm –Stream Stabilization Contact the County to determine if local, state or federal permits are required before doing any of the following in a wash, stream, lake or river (whether or not water is flowing): Remove soil, rock or plant material from a streambed or bank; Place any waste, material or structures within or on the bank– even if to armor or stabilize; Divert, obstruct or otherwise modify the bed, channel or bank; or Dispose or deposit debris, liquid, solid waste or soil. Failure to do so may result in violations of local, state and/or federal law – Call (951) 955-2004 for assistance from the County

Before the Storm – Sand Bagging Stage and store sand and sandbags before the storm. You can obtain sand and sandbags from the local hardware store. For information regarding how to fill a sandbag: http://www.rcflood.org/FloodSafety.aspx Sandbags will last as long as they don’t have a hole. If the bags are reusable, residents should keep them for the next major rainstorm. To discard, distribute sand in a flower bed or over a lawn, and then throw away the empty bags. It is illegal to dump sand in a stream, in the gutter, or in the storm drain system.

During the Storm Avoid unnecessary trips, only travel in emergency situations. DO NOT “sightsee” in flooded areas. DO NOT attempt to go around barricades. DO NOT try to cross low water crossings that have flowing water. Two feet of flowing water can move a 2,000 pound car. 6 inches of water can sweep you off your feet.

During the Storm In an emergency dial “911” Clogged channels – call 951.955.1230 Clogged inlets, road culverts, roadside ditches – call 951.955.1230
