The first step is to try to figure out where the water is coming from. Runoff due to the slope of your property, downspouts and water across driveways can often be mitigated by Low Impact Development (LID) Methods. There are many resources available to help resolve drainage issues on your property.
Here are a few:
Rain Garden Handbook for Western Washington
Whidbey Island Conservation District
Washington State University Extension
If water runoff from an Island County road, ditch or culvert is impacting your private property, please advise the Island County Public Works Department at 360.679.7331. Questions on erosion/slope stability may be directed to the Development Coordinators through the Planning Department at 360-679-7339.
Please note: On the older Plats within Island County the developers, in the dedication of the plat, included language stating:
"… Also the right to drain all streets over any lot or lots where water might take a natural course after the street or streets are graded.”
As a result of this language, Island County has the right to send public roadway drainage over and across private property. If the amount of water is considered excessive and occurs on a frequent basis, Island County Public Works will investigate.
