    Marmot Road/West Creek culvert replacement environmental assessment, finding of no significant impact, and decision record
    (2007-05) United States. Bureau of Land Management. Salem District
    EA proposes action to remove the perched 42 inch culvert and replace it with a structure that will allow upstream movement of fish and reduce the erosive energy of the stream. The culvert would be removed and replaced with a bridge that will link the road on either side of the creek. The existing fill over the culvert would be removed with a tracked excavator, and then the culvert would be removed. Additional excavation would be required prior to installation of the bridge footings. Backfill would be placed behind the bridge footings and the precast bridge would be installed. FONSI finds no environmental impact statement is needed.

    Maxfield Creek density management project 2 aquatic habitat restoration and project 1 transportation aquatic habitat restoration final decision and decision rationale
    (2007-01) United States. Bureau of Land Management. Salem District
    Announces decision to implement projects, including replacing one culvert that is undersized and a barrier to fish passage with a larger diameter, correctly positioned culvert. A series of rock and log weirs may be needed downstream of the culvert to prevent head-cutting and maintain passage through the culvert. The proposed action will also place approximately 30 pieces of large woody debris (LWD) through the west half of Section 19 in Maxfield Creek using selected trees from upland treatment areas and transported and placed in the stream via helicopter. To reduce impacts to Maxfield Creek, approximately 1,200 feet of existing road (Road # 10-6-14) will be decommissioned with a comparable distance constructed farther away from Maxfield Creek. In addition, two stream crossings (fish passage barrier culvert and undersized culvert) will be eliminated and one culvert will be installed on an intermittent stream.

    Moon Creek projects decision record
    (2008-12) United States. Bureau of Land Management. Salem District
    Announces approval of projects, including: 1) density management thinning on approximately 420 acres of 30-55 year old, relatively dense Douglas-fir and western hemlock stands, construct and then fully decommission approximately one-half mile of new temporary road, renovate approximately 2.5 miles of existing road and then fully decommission 2 miles of those roads, and reopen and then re-decommission approximately 4.5 miles of previously decommissioned rocked road; and 2) coarse wood development project on approximately 300 acres of forest stands between about 90 and 125 years old.

    Moon Creek projects finding of no significant impact
    (2008-12-17) United States. Bureau of Land Management. Salem District
    Finds NEPA documentation fully covers plan to to conduct two different project types in the Late Successional Reserve portion of the Northern Coast Range Adaptive Management Area and the Riparian Reserve land use allocations. The first project is a density management thinning of approximately 420 acres. Thinning would occur on federal land in portions of Township 3 South, Range 8 West, Sections 3, 11, 13, 14, 15, and 24, Willamette Meridian. The second project involves coarse wood development treatments on approximately 300 acres.

    Upper and Lower Alsea River Watershed fish passage restoration environmental assessment and finding of no significant impact
    (2008-11-19) United States. Bureau of Land Management. Salem District
    Upper and Lower Alsea River Watershed Fish Passage Restoration is a proposal to restore fish passage to approximately three miles of anadromous and resident fish habitat. The project would replace six stream crossing culverts that currently block fish passage with six culverts that would allow fish passage. The project would also remove a portion of a trash rack that also blocks fish passage.

    Yamaha LSR enhancement/aquatic habitat restoration environmental assessment and finding of no significant impact
    (2007-10-16) United States. Bureau of Land Management. Salem District
    Proposes six projects: Project 1 (LSR Enhancement) is a proposal to hasten the development of late-seral wildlife habitat stand structure on approximately 159 acres of early and mid-seral forest land. Project 2 (Young Stand Enhancement) is a proposal to promote late-seral forest conditions on approximately 23 acres within a 20 year old stand by variable density management. Project 3 (Snag/CWD Creation & Large Tree Release) is a proposal to create large, hard snags and CWD structure which is lacking in the project area and to release the largest trees with the fullest crowns in selected mid and late-seral stands. Project 4 (Large Woody Debris Placement) is a proposal to enhance approximately 5 miles of fish and aquatic habitat by the placement of conifer trees and logs into streams. Project 5 (Trout Creek County Road Culvert Replacement) is a proposal to replace two existing concrete culverts on Road 14-7-22 with an arched pipe culvert that would reduce sediment from entering a stream and eliminate a barrier to fish migration. Project 6 (South Mountain County Road Improvement) is a proposal to improve road drainage (installing ditches, water run-outs and culverts) and infrastructure (placement of approximately six inch lift of rock) to 3.5 miles of the South Mountain County Road, thereby reducing erosion run-off and improving water quality.
