Dos and Don'ts in Floodplains

Floodplains can be very hazardous, so it's important to know what to do and what not to do to improve your safety.  It is important to realize that some of the things that might protect you may hurt your neighbors.

DON'T build structures close to a wash; at some point in time they may be flooded.

DON'T divert drainage onto your neighbor's property­ this is an illegal activity and the results can be disastrous.

DON'T block washes with fences­ debris will catch on fences and divert water where it is least expected.

DON'T install air conditioners, evaporative coolers, electrical service boxes,water heaters or other appliances below the base flood depth.

DON'T risk your life by walking or driving around barricaded dip sections or across flooded washes­ they're dangerous! Six inches of moving water can knock you off your feet. Two feet of water can carry your car away.
