As part of Washington State planning for growth management in 1998, Kitsap County placed Illahee into the East Bremerton Urban Growth Area with urban zoning for the Illahee community.
As Kitsap County updated its Comprehensive Growth Management Plan in 2006, one of the questions presented was whether Illahee should be part of Bremerton or part of a new City of Silverdale.
A large consensus among Illahee residents at this time was not to be part of the urban growth plan of either city. Thus, two years later in 2008, Kitsap County and citizens of Illahee had defined and approved a community plan for the Illahee.
The details of the Illahee Community Plan can be found at the following Kitsap County Internet page: http://www.kitsapgov.com/dcd/community_plan/subareas/Illahee/subarea_finaled.htm
