The subdivision of land into lots is governed in Washington State by chapter 58.17 RCW and by Grays Harbor County Code Title 16 which was adopted under that chapter's authority. Grays Harbor County Code Chapter 16.20 governing long subdivisions applies to the division of land into five  (5) or more lots, any of which is less than five acres.  Planning staff will review your application and submittal documents for completeness and compliance with GHC subdivision, zoning, and environmental regulations.  If the proposal is consistent with the local regulations, staff will issue preliminary approval of the subdivision.

  • Final plat approval is issued and the subdivision is recorded.
