Washington Revised Code Title 76. Forests and Forest Products § 76.13.130. Small parcels--Alternative management plans

On parcels of twenty contiguous acres or less, landowners with a total parcel ownership of less than eighty acres shall not be required to leave riparian buffers adjacent to streams according to forest practices rules adopted under the forests and fish report as defined in RCW 76.09.020. These landowners shall be subject to the permanent forest practices rules in effect as of January 1, 1999, but may additionally be required to leave timber adjacent to streams that is equivalent to no greater than fifteen percent of a volume of timber contained in a stand of well managed fifty-year old commercial timber covering the harvest area. The additional fifteen percent leave tree level shall be computed as a rotating stand volume and shall be regulated through flexible forest practices as the stream buffer is managed over time to meet riparian functions.

On parcels of twenty contiguous acres or less the small forestland owner office shall work with landowners with a total parcel ownership of less than eighty acres to develop alternative management plans for riparian buffers. Such alternative plans shall provide for the removal of leave trees as other new trees grow in order to ensure the most effective protection of critical riparian function. The office may recommend reasonable modifications in alternative management plans of such landowners to further reduce risks to public resources and endangered species so long as the anticipated operating costs are not unreasonably increased and the landowner is not required to leave a greater volume than the threshold level. To qualify for the provisions of this section, parcels must be twenty acres or less in contiguous ownership, and owners cannot have ownership interests in a total of more than eighty acres of forestlands within the state.
