What is a Conversion Option Harvest Plan (COHP)?
A “Conversion Option Harvest Plan” (COHP) is a timber harvest plan developed by the landowner and approved by Pierce County, indicating the limits of timber harvest, road location, critical areas, etc.


  • The proposed COHP is subject to review and approval by Pierce County. The COHP must comply with Title 18E, Pierce County Development Regulations – Critical Areas (Wetlands, Streams, Wildlife Habitat, and Steep Slopes) and Title 18H, Pierce County Development Regulations – Forest Practices.

  • The approved COHP typically includes conditions of approval, resulting from Pierce County’s review, which the landowner must follow during timber harvest.

  • The Pierce County-approved COHP is submitted by the landowner/applicant to the Washington State Department of Natural Resources (DNR) and is attached to the approved Class II or Class III State Forest Practice Application (FPA). The COHP becomes the conditions of approval for the FPA.

  • When followed, the COHP releases the landowner from the otherwise mandatory six-year development moratorium which is imposed on the proposed harvest area(s) by Pierce County for DNR-approved logging permits.

  • The COHP grants no other rights to the landowner and does not release the landowner from state reforestation requirements.
