 2016 Island Annexation ProcessUpdated September 15, 2016 

As the city limits have expanded over time, several small "islands" or pockets of Chelan County have remained. Over the past five years, property owners completing this annexation process have reduced many of these island areas in size. While it is anticipated this approach and process will naturally continue, providing services in the current size and location of the islands has become increasingly inefficient for both the City and the County.

To see if your property is within one of the islands - please click here to see the detailed location maps.

Chelan County and the City of Wenatchee agree that both residents and service providers could benefit through increased service efficiency if the islands become part of the city. - August 29, 2016 Letter from Chelan County Commissioners. To facilitate this process, the Mayor and City Council initiated the 2016 annexation process outlined below.
