Amounts placed in the conservation futures fund shall be used to acquire rights and interests in farm and agricultural land, open space land, timberland, and public access to water on a voluntary basis, as established in Chapter 84.34 RCW and for the maintenance and operation of any property acquired with these funds. The purpose is to protect, preserve, maintain, improve, restore, limit the future use of, or otherwise conserve the property for public use or enjoyment. Included are debt issuances and debt service costs related to bond monies and repayment in instances where bonds are issued to further these purposes. Until withdrawn for such use, the monies accumulated in the fund may be invested in interest-bearing securities. It shall be the joint responsibility of the Clallam County Treasurer and the County Auditor to account for all aspects of this fund. Any money remaining in the fund upon fund closure shall be transferred as directed by the Board of County Commissioners.
