High Ground Water
Dealing with High Groundwater Issues
If water over driveway:
  • ​Get a vehicle on the opposite side of the water so you have ingress and egress
    • Check the water depth then call a tow company and see if they have a tow truck that can pass through the water and that uses car carrying technology to come pick up your car and move it to the opposite side. You will need waders or small boat to get back and forth.
    • Call a relative or friend that can put a spare car on the opposite side.
    • Make arrangements with relative or friend with high water 4x4 for transportation needs or bring you a small boat.
  • If you can cross the water in waders or by small boat, but can’t get a vehicle stationed at the other side:
    • Make arrangements with relative or friend for transportation needs.
       
If you want to leave your house until water recedes:
  • ​Make arrangements with relative or friend with high water 4x4 for transportation needs.
  • Call Thurston County Emergency Management (360.867.2800). They may be able to arrange a onetime transport if you have no other options.
If you have your home or other structure being flooded by high groundwater:
  • ​Sandbagging alone does not stop high groundwater; the water will rise equally on either side of the sandbag unless one side is impervious. You will need a pump on the side you are protecting; this basically creates a circulating system because as you pump the water over the sandbag it puts more pressure on the opposite side which pushes more water up on the side you are pumping from. It is a good idea to lay a plastic sheet or tarp down that is weighted down by sandbags to create a clean location to pump the water from. This reduces pump clogging and burnout.
  • If your home is being flooded contact Thurston County Emergency Management about the potential of elevating your home.
  • If you have concerns about your septic or water well see the Environmental Health website at http://www.co.thurston.wa.us/health or contact them with questions at (360) 867-2673.
If you have an emergency and need to call 911:
  • ​Be clear about driveway condition so they can come prepared.
