Develop and maintain a Transportation Plan that meets Aquatic Conservation Strategy objectives and also serves the needs of users in an environmentally sound manner. Arterial and major collector roads will form the backbone of the transportation system in the planning area.

Correct problems associated with high road density by emphasizing the reduction of minor collector and local road densities where those problems exist.

Manage roads to meet the needs identified under other resource programs (e.g., seasonal road closures for wildlife). Road management is mentioned or implied primarily under Aquatic Conservation Strategy Objectives, Riparian Reserves, Late-Successional Reserves, Water Quality and Soils, Wildlife, Fish Habitat, Special Status and SEIS Special Attention Species Habitat, Timber Resources, and Recreation.

Land Use Allocations

There are approximately 2,000 miles of roads on BLM administered land in the Eugene District.

Management Actions/Direction for Riparian Reserves

Cooperate with Federal, State, and County agencies and work with parties with road use agreements to achieve consistency in road design, operation, and maintenance necessary to attain Aquatic Conservation Strategy objectives.

For each existing or planned road, meet Aquatic Conservation Strategy objectives as follows:

  1. Complete watershed analyses, including appropriate geotechnical analyses (i.e., examining soil and rock conditions in riparian and stream crossings) prior to construction of new roads or landings in Riparian Reserves;

  2. Minimize road and landing locations in Riparian Reserves;

  3. Prepare road design criteria, elements, and standards that govern construction and reconstruction;

  4. Prepare operation and maintenance criteria that govern road operation, maintenance, and management;

  5. Minimize disruption of natural hydrologic flow paths, including diversion of streamflow and interception of surface and subsurface flow;

  6. Restrict side casting as necessary to prevent the introduction of sediment to streams; and

  7. Avoid wetlands entirely when constructing new roads.

Determine the influence of each road on the Aquatic Conservation Strategy objectives through watershed analysis. Meet Aquatic Conservation Strategy objectives by

  1. reconstructing roads and associated drainage features that pose a substantial risk;

  2. prioritizing reconstruction based on current and potential impact to riparian resources and the ecological value of the riparian resources affects; and

  3. closing and stabilizing, or obliterating and stabilizing roads based on the ongoing and potential effects to Aquatic Conservation Strategy objectives and considering short and long-term transportation needs.

Design and construct new culverts, bridges, and other stream crossings and improve existing culverts, bridges and other stream crossings determined to pose a substantial risk to riparian conditions. New structures and improvements will be designed to accommodate at least the 100-year flood, including associated bedload and debris. Priority for upgrading will be based on the potential impact and the ecological value of the riparian resources affected. Crossings will be constructed and maintained to prevent diversion of streamflow out of the channel and down the road in the event of crossing failure.

Minimize sediment delivery to streams from roads. Out sloping of the roadway surface is preferred, except in cases where Out sloping would increase sediment delivery to streams or where Out sloping is infeasible or unsafe. Route road drainage away from potentially unstable channels, fills, and hill slopes.

Provide and maintain fish passage at all road crossings of existing and potential fish-bearing streams (e.g., streams that can be made available to anadromous fish by removing obstacles to passage).

Develop and implement a Transportation Management Plan that meets the Aquatic Conservation Strategy objectives. As a minimum, this plan will include provisions for the following activities:

  1. Inspections and maintenance during storm events

  2. Inspections and maintenance after storm events

  3. Road operation and maintenance giving high priority to identifying and correcting road drainage problems that contribute to degrading riparian resources

  4. Traffic regulation during wet periods to prevent damage to riparian resources

  5. Establish the purpose of each road by developing the road management objective.

Management Actions/Direction for Late-Successional Reserves

Road construction in Late-Successional Reserves for silvicultural, salvage, and other activities generally is not recommended unless potential benefits exceed the costs of habitat impairment. If new roads are necessary to implement a practice that is otherwise in accordance with these guidelines, they will be kept to a minimum, be routed through unsuitable habitat where possible, and designed to minimize adverse impacts. Alternative access, such as aerial logging, should be considered to provide access for activities in reserves.

Remove trees along rights-of-way if they are a hazard to public safety. Consider leaving material on-site if available coarse woody debris is inadequate. Consider topping of trees as an alternative to felling.

Key Watersheds - Reduce existing road mileage within key watersheds. If funding is insufficient to implement reductions, neither construct nor authorize through discretionary permits a net increase in road mileage in Key Watersheds.

Management Actions/Direction for All Land Use Allocations

The Management Actions/Direction listed under Riparian Reserves also apply to all land use allocations.

Prepare a District wide Transportation Management Plan after approval of the RMP. The management plan will specifically address recreation use, road densities, road closures, wildlife protection, water quality, timber management, construction and maintenance standards, fire suppression, and coordination with adjacent landowners. Address road management planning on a watershed basis consistent with Late-Successional Reserves, Riparian Reserves, and other major allocations. Specific road closures will be determined in the watershed analysis process.

Determine standards for new road construction during the project planning process. Standards will be the minimum necessary to meet resource and allocation objectives (recreation site, timber sale, key watershed, etc.) while having minimal impacts on the environment.

Minimize new road construction in areas with fragile soils to reduce impacts to soils, sensitive resources, water quality, and fisheries. Stabilize existing roads where they contribute to significant adverse effects on these resources.

Locate, design, construct, and maintain roads to standards that meet management objectives in accordance with the District Transportation Management Plan.

Site and schedule road construction to avoid mass movement of slopes.

Where appropriate to the anticipated use, surface roads to minimize sedimentation.

Vegetate cuts and fillslopes using native species capable of supporting vegetation to stabilize them prior to winter rains.

Stabilize temporary roads prior to winter rains and rehabilitate them after use.

Follow Best Management Practices (see Appendix C) for water quality and soil productivity to mitigate adverse effects on soils, water quality, fish, and riparian habitat during road construction and maintenance.

Reduce road density by closing minor collector and local roads in areas or watersheds where water quality degradation, big game harassment, or other road related resource problems have been identified.

Acquire water rights for road management purposes.

Specifically address, in either the Transportation Management Plan or in a watershed analysis, stabilizing existing roads located on fragile soils. These would include watersheds with water quality limited streams and other areas of the District where soil/water quality problems are known to exist.

Avoid road construction in special areas, i.e., ACECs and RNAs, and special habitats.
