The County encourages all residents to get ready before the rains begin. Historical storm events have caused heavy rains and winds resulting in mudslides, downed trees, flooding, and property damage.
Avoid problems by preparing yourself and your property now!
Know Your Flood Risk
Evaluate your property. Where does rain pool? How does runoff drain, and to where? Also get to know your neighborhood’s drainage facilities. Flooding can be caused by drainage inlets, gutters, ditches, pipes, over-flowing creeks, or levee breaks. FEMA Floodplain Program
Prepare For Your Needs
Get emergency supplies in order. Plan for food, water, medical, and personal comfort needs for each household resident. Plan an evacuation route in case of fast rising water. Ready.gov
Prepare Your Home and Property
Clean gutters. Clear leaves off of nearby storm drains. Make sure pipes and ditches on your property are not obstructed. If you live near a creek, take special precautions.
