More than one of these attributes may apply to a single route segment. If this is the case, choose the value that is highest in the hierarchy. All-American Road: All-American Roads are designated by the US Secretary of Transportation for their scenic, historic, natural, cultural, recreational, or archeological qualities and are considered to be the "best of the best." These routes represent the finest examples of scenic drives in America, making them "designations unto themselves." These routes must have prior designation as a State Scenic Byway or State Scenic and Recreational Highway to be submitted for national designation. National Scenic Byway: National Scenic Byways are designated by the US Secretary of Transportation for their scenic, historic, natural, cultural, recreational, or archeological qualities and merit national level recognition. These routes must have prior designation as a State Scenic Byway or State Scenic and Recreation Highway to be submitted for national designation. BLM Back Country Byway: Back Country Byways are designated through a resource management plan (RMP) and showcase the variety of richness of BLM's off-the-beaten track public lands. Most of the byways are either paved or graded gravel and dirt roads, passable in ordinary passenger cars. Others are safely driven only in a high-clearance truck or 4-wheel drive vehicle. National Forest Scenic Byway: The Chief of the Forest Service administratively designates National Forest Scenic Byways. These routes represent the best of the roads running through the national forests and showcase outstanding national forest and grassland scenery. State Scenic Byway (OR): Oregon State Scenic Byways are designated by the Oregon Transportation Commission. They have high national or statewide appeal, feature historic, recreational, archeological, cultural, or natural appeal in addition to scenic qualities, are a minimum of 30 miles long, and must be passable by passenger car. State Tour Route (OR): Oregon State Tour Routes are designated by the Oregon Transportation Commission. They have high local or regional appeal, feature similar qualities as State Scenic Byways, are a minimum of 20 miles long, and must be passable by passenger car or four-wheel drive vehicle. State Scenic and Recreational Highway (WA): Washington State Scenic and Recreation Highways are designated by the state legislative statute for the purpose of ensuring the state's most spectacular and diverse landscapes, including scenic, natural, recreational, cultural, and historic resources. State Scenic Bikeway (OR): Oregon State Scenic Bikeways are designated by the Oregon Recreation and Parks Commission. Bikeways are signed bike routes on roads and bicycle paths that provide access to national, state, or regional resources of superlative quality and scenic splendor. They can be linear routes a minimum of 40 miles long, or a loop a minimum of 5 miles long. Auto Tour Route: These routes are usually self-designated by a variety of entities including counties, state tourism offices, local chambers of commerce, regional industry groups, and land management agencies. They usually highlight and market a local or regional characteristic or product such as a collection of covered bridges, waterfalls, wineries, farm stands, etc. A subset of auto tour routes focuses specifically on wildlife viewing opportunities, including the OR and WA Birding Trails. National Scenic Trail: Part of the congressionally designated National Trail System, these trails comprise of continuous protected scenic corridors for outdoor recreation. National Historic Trail: Part of the congressionally designated National Trail System, these trails recognize broad facets of history such as prominent past routes of exploration, migration, trade, communication, and military action. Historic trails generally consist of remnant sites and trail sections, and thus are not necessarily continuous. National Recreation Trail: Part of the congressionally designated National Trail System, these trails are recognized by the Federal Government as contributing to the National Trail System. They vary in length, terrain, difficulty, and accessibility. National Geologic Trail: Part of the congressionally designated national geologic trail. It is a network of touring routes with interpretive opportunities distributed across the vast west. May consist of both foot and vehicle travel.

BLM interdisciplinary teams make recommendations about trail closures based on impacts to resources and resource protection. These implementation-level NEPA-supported decisions are based on Resource Management Plan (RMP) management direction and are implemented following completion of an EA, an EIS, or a Travel and Transportation Management Plan. The Trail Closure Status field is directly related to the Trail Use field, i.e., trail closure status only pertains to the predominant mode of transportation for which the trail is managed. For information on street legal vehicle closures, refer to the Closure Status field. For information on OHV closures, refer to the OHV Limited Season Designation field. For information on the inter-relatedness of these fields, refer to the OHV Route Designation field. The OHV Route Designation field is not the same as the predominant mode of transportation for which the trail is managed; however, there are inherent logical Trail Closure Status values associated with the different OHV Route Designation, OHV Limited Vehicle Type, and OHV Limited Season values. This field does not capture short-term closure information. This information is captured with a spatial overlay with the defining closure polygon data. Fire, landslides, and eagle nesting are examples of short-term closure situations.

BLM String 2 0 0 PLANCAT PlanCat The Planning Category field represents BLM management decisions. BLM interdisciplinary teams make recommendations about route planning categories based on intended identified use of the linear asset. These implementation-level NEPA-supported decisions are based on Resource Management Plan (RMP) management direction and are implemented following completion of an EA, an EIS, or a Travel and Transportation Management Plan. The intent of this field is to identify the routes where the BLM has the authority to make a designation/decision about the route and the planning category of a route. The BLM has the authority to make designation/decisions on routes that the BLM owns and controls as well as private industry routes within a reciprocal right-of-way (RROW) that the BLM controls. Route ownership and control are defined in the Ownership field. Routes formally designated as a road, primitive road, or trail that are the subject and result of a Travel Management Plan (TMP) make up the BLM Transportation System. Information about these routes is input and maintained in FAMS. Routes can be entered into FAMS as a road, primitive road, or trail without a TMP as long as the information in FAMS is updated as necessary after a TMP is completed. Changes to the BLM’s transportation system, as recorded in FAMS, may occur as part of the formal evaluation and designation process through one of four events: a) Record of Decision (ROD) – for a Resource Management / Environmental Impact Statement (RMP/EIS) or an amendment of an RMP/EIS. b) Decision Records for an Activity Plan, Plan Amendment/Environment Assessment (EA). c) Federal Register Notice Action (under authority of 43 CFR 8341.2, 8364.1, 8365.3-6, or 9268.3) that has a follow-up land-use planning action and associated NEPA action. d) Management decision of appropriate routes in an area that has been designated open to off-highway vehicle use. Routes owned by private industry or another agency can be entered into FAMS as a road, primitive road, or trail when the BLM has an interest in these routes as a result of a maintenance agreement or a reciprocal right-of-way agreement. These routes are part of the BLM Transportation System. BLM Road: A route managed for use by low-clearance vehicles having four or more wheels and maintained for regular and continuous use. The BLM owns and controls the route. Roads are part of BLM’s Transportation System; FAMS is the system of record for these routes. BLM Primitive Road: A route managed for use by four-wheel drive or high-clearance vehicles. Primitive roads do not normally meet any BLM road design standards. The BLM owns and controls the route. Primitive Roads are part of BLM’s Transportation System; FAMS is the system of record for these routes. BLM Trails: A route managed for human-powered, stock, or off-highway vehicle forms of transportation or for historical or heritage values. Trails are not generally managed for use by four-wheel drive or high-clearance vehicles. The BLM owns and controls the route. Trails are part of BLM’s Transportation System; FAMS is the system of record for these routes. BLM WSA Ways: Routes within a Wilderness Study Area (WSA) that are not excluded from the WSA, as in the case of a “cherry-stem” road. They were officially recognized and mapped (as “Ways”) during the FLPMA Sec. 603 Wilderness Inventories (Sec. 603 WSAs) and any Sec. 202 inventories meeting the criteria of the Utah Settlement Agreement (Sec. 202 WSAs). The term “way” derives from a “roadless” definition in the Congressional Record adopted in BLM’s 1978 Wilderness Inventory Handbook, which concludes that “a way maintained solely by the passage of vehicles does not constitute a road.” Based on the complete “roadless” definition, BLM WSA Ways are defined as “A trace maintained solely by the passage of vehicles which has not been improved and/or maintained by mechanical means to insure relatively regular and continuous use.” The BLM owns and controls the route. WSAs are NOT part of BLM’s Transportation System; GTRN is the system of record for these routes. BLM Primitive Route: Routes within (not forming a boundary and not excluded in a “cherry-stem”) a Wilderness Inventory Unit found to possess Wilderness Characteristics. They were found to not be “improved or maintained by mechanical means to insure relatively regular and continuous use.” They are kept passable solely by the passage of vehicles and no hand or power tools have been applied. There is a Land Use Plan decision to protect the Wilderness Characteristics of this Wilderness Characteristics Unit. The ultimate disposition of these routes will depend on the specific protections applied to the area via the RMP and any step-down TMP decisions. The BLM owns and controls the route. Primitive Routes are NOT part of BLM’s Transportation System; GTRN is the system of record for these routes. BLM Interim Primitive Route: Routes within (not forming a boundary and not excluded in a “cherry-stem”) a Wilderness Inventory Unit found to possess Wilderness Characteristics. They were found to not be “improved or maintained by mechanical means to insure relatively regular and continuous use”. They are kept passable solely by the passage of vehicles and no hand or power tools have been applied. There is not a Land Use Plan decision to protect the Wilderness Characteristics of this Wilderness Characteristics Unit. The ultimate disposition of these routes will depend on the specific management allocations applied to the area via the RMP and any step-down TTMP decisions. Unless otherwise prohibited, these primitive routes may be managed at BLM discretion (including improvement by mechanical means) with appropriate NEPA compliance, including analysis of impacts to wilderness characteristics. A change in route status should be reflected in the Wilderness Inventory Report and may warrant reevaluation of the Wilderness Inventory Unit. The BLM owns and controls the route. Interim Primitive Routes are may or may not currently be part of BLM’s Transportation System; GTRN is the system of record for these routes. Following any Land Use Plan decision to protect the Wilderness Characteristics of the Wilderness Inventory Unit, these routes will need to be re-classified as BLM Primitive Routes. BLM Permanently Removed Route: Routes identified to be permanently removed during a BLM Travel and Transportation Management Plan (TTMP); a decision has been made during the planning process not to retain these routes. These routes have a closure rehab/decommissioning plan. BLM Permanently Removed Route is synonymous with Linear Disturbance. Permanently Removed Routes may include engineered (planned) as well as unplanned routes. Routes within a legislative designation, e.g., wilderness designation, that are not designated as a BLM Trail are included in this category. On-the-ground evidence of these routes may exist for some time after the decision is made to permanently remove the routes. The routes remain in the GIS system in order to provide spatial reference of decisions. The BLM owns and controls the route. Permanently Removed Routes are NOT part of BLM’s Transportation System as they are no longer routes; GTRN is the system of record for these routes. BLM Temporary Route: A short-term overland road, primitive road, or trail that is authorized or acquired for the development, construction, or staging of a project or event that has a finite lifespan. Temporary routes are a subset of BLM Permanently Removed Routes and do not need to be moved to the BLM Permanently Removed Route category at the close of the project. Roads built for a timber sale in western Oregon are an example of a temporary route and have a maximum life-span of three years. Routes identified in a mining claim Plan of Operation are another example of a temporary route and have a life-span that may extend to a couple of decades. The project is responsible for remediation at the close of the project; temporary routes will never become a designated route. The BLM owns and controls the route. Temporary Routes are NOT part of BLM’s Transportation System; GTRN is the system of record for these routes. Temporary Routes tracked for reporting in association with the BLM Forest Management Programmatic for Western Oregon (BLM Forest Management Programmatic) Biological Opinion date 03/09/2018 issued by National Marine Fisheries Service covering forest management activities implemented by the two 2016 western Oregon RMPs will need to have construction year, average width, ownership designation and surface type populated with valid values. Total miles of Temporary Routes will use GIS Miles, which is an auto-calculated field. BLM No TTMP Decision: A route that is within the BLM decision space. That is, the BLM owns and controls the route and/or BLM controls a private road within a reciprocal right-of-way (RROW) on BLM land. No BLM Travel and Transportation Management planning decision has been made on the route. There is no route-level record of decision (ROD). PVT RROW Road on BLM Land: A route managed for use by low-clearance vehicles having four or more wheels, and maintained for regular and continuous use. The road is on BLM land, i.e., the BLM controls the road, but the road is owned by a private timber company. The road is encumbered by a reciprocal right-of-way (RROW). The BLM has the authority to make an OHV Route Designation on these routes, including decisions that limit the OHV vehicle type or season. Privately owned RROW roads may or may not be part of BLM’s Transportation System; FAMS or GTRN are the system of record for these routes. Non-BLM Route: BLM does NOT have the route designation authority, i.e., BLM does not own or control the route. Non-BLM Transportation Features include State and US Highways, USFS and other agency roads, county roads, and private roads on BLM land not encumbered by a RROW agreement, all of which may incidentally cross BLM lands.

BLM interdisciplinary teams make recommendations about route OHV designation based on impacts to resources and resource protection as well as to balance the recreational needs of the public and reduce conflict between different user groups. These implementation-level NEPA-supported decisions are based on Resource Management Plan (RMP) management direction and are implemented following completion of an EA, an EIS, or a Travel and Transportation Management Plan. This field represents the OHV route designation on routes as described in terms of Code of Federal Regulation 43 CFR Part 8342 as Open, Limited, or Closed. An off-highway, or off-road, vehicle is defined as: (a) Any motorized vehicle capable of, or designed for, travel on or immediately over land, water, or other natural terrain, excluding: (1) Any nonamphibious registered motorboat; (2) Any military, fire, emergency, or law enforcement vehicle while being used for emergency purposes; (3) Any vehicle whose use is expressly authorized by the authorized officer, or otherwise officially approved; (4) Vehicles in official use; and (5) Any combat or combat support vehicle when used in times of national defense emergencies. BLM IB 2015-060 classifies e-bikes as motorized vehicles; they are considered off-highway vehicles when being operated off a highway. Mechanized vehicles, e.g., non-motorized bicycles, are not considered off-highway vehicles. The OHV Route Designation field does not apply to mechanized use on a route. See the Trail Use field for mechanized route use. The BLM has the authority to make OHV route designations on routes that the BLM owns and controls as well as private industry routes within a reciprocal right-of-way (RROW) that the BLM controls. Route ownership and control are defined in the Ownership field. OHV route designations are related to, but differ, from off-highway vehicle area designations. OHV area designations cover the extent of all BLM surface jurisdiction lands and are determined through a Land Use Planning process (Resource Management Plan (RMP)). OHV route designations apply to individual routes and are determined through the Travel Management Planning process (TMP). A Travel Management Plan can occur concurrently or subsequently with a Land Use Plan (LUP). The OHV area designation sets the over-arching constraints of the routes within an OHV area designation. • If an OHV area designation is open, then all routes within the area will have an open OHV route designation. • If an OHV area designation is closed, then all routes within the area will have a closed OHV route designation. • If an OHV area is limited, then routes within the area can have an open, closed, or limited route designation. This field is related to the Planning Category, Planning Identifier, Off-highway Vehicle Limited Vehicle Type, Off-highway Vehicle Limited Season, Road Use, Trail Use, Closure Status, and Trail Closure Status fields (see the Off-Highway Vehicle (OHV) Route Designation Compatibility Matrix). Open Route: All off-highway vehicle use on the route is permitted at all times, by all OHV vehicle types, subject to operating regulations and vehicle standards. Limited Route: Off-highway vehicle use on the route is restricted by season and/or OHV vehicle type. Closed Route: Off-highway vehicle use on the route is prohibited at all times, by all OHV vehicle types. Non-TTMP Route: Off-highway vehicle use on the route is not applicable because the route is permanently closed, e.g., full decommission (FD), obliterated (OB), closed permanently. Non-BLM Route: BLM does NOT have the route designation authority, i.e., BLM does not own or control the route. Non-BLM Transportation Features include State and US Highways, USFS and other agency roads, county roads, and private roads on BLM land not encumbered by a RROW agreement, all of which may incidentally cross BLM lands.

The OHV area designation sets the over-arching constraints of the routes within an OHV area designation. • If an OHV area is limited, then routes within the area can have an open, closed, or limted route designation. • If an OHV route designation is limited, then the OHV area designation must be limited. This field is related to the Planning Category, Planning Identifier, Off-highway Vehicle Route Designation, Off-highway Vehicle Limited Vehicle Type, Road Use, Trail Use, Closure Status, and Trail Closure Status fields. For a view of the inter-relatedness of these fields, refer to the OHV Route Designation. In the trails feature class, the off-highway vehicle limited vehicle type must have the same value as the trail use field, unless the trail is coincident with the roads feature class. The ability to limit OHV vehicle types on roads and primitive roads, which are all managed for street legal vehicles, necessitates having both fields. UTV (Class IV, OR – 801.194): Any motorized vehicle that: • Travels on four or more pneumatic tires that are six inches or more in width and that are designed for use on wheels with a rim diameter of 14 inches or less; • Is designed for or capable of cross-country travel on or immediately over land, water, sand, snow, ice, marsh, swampland, or other natural terrain; • Has non-straddling seating; • Has a steering wheel for steering control; • Has a dry weight of 1,800 pounds or less; and • Is 65 inches wide or less at its widest point. ATV (Class I, OR – 801.190): A motorized, off-highway recreational vehicle 50 inches or less in width with a dry weight of 1,200 pounds or less that travels on three or more pneumatic tires that are six inches or more in width and that are designed for use on wheels with a rim diameter of 14 inches or less, uses handlebars for steering, has a seat designed to be straddled for the operator, and is designed for or capable of cross-country travel on or immediately over land, water, sand, snow, ice, marsh, swampland or, other natural terrain. Motorcycle (Class III, OR – 801.194): A motorcycle that travels on two tires and that is actually being operated off highway. BLM IB 2015-060 classifies e-bikes as motorized vehicles as defined at 43 CFR 8340.5. NA Route: The OHV Route Designation is open route, closed route, or non- TTMP route or the OHV Route Designation is limited, but does not have a vehicle type restriction.

This field does not apply if the OHV Route Designation is open or closed; if the OHV Route Designation is open or closed then leave this field blank. OHV seasonal limitations are typically related to wildlife habitat or resource protection. Actual seasonal end dates are based on local direction and may deviate from the end date listed in the data. The seven primary groups and general date ranges of protection are: • Bat (White-Nose Syndrome) (Anytime) • Deer (November through March) • Elk (December through March) • Raptor (March through July) • Sage Grouse (May through June) • Resource Protection (Generally Wet Season) • Fire (Anytime) Seasonal limitations should be entered Wildlife Group MM/DD – MM/DD. A semi-colon should be used to separate multiple date ranges, e.g., Raptor 03/01 – 07/31; Sage Grouse 05/01 – 06/30. Additional time of day restrictions can be added after the date, e.g., Raptor 03/01 – 07/31; Sage Grouse 05/01 – 06/30, 2 hours before sunrise to 1 hour after sunrise. An off-highway, or off-road, vehicle is defined as: (a) Any motorized vehicle capable of, or designed for, travel on or immediately over land, water, or other natural terrain, excluding: (1) Any nonamphibious registered motorboat; (2) Any military, fire, emergency, or law enforcement vehicle while being used for emergency purposes; (3) Any vehicle whose use is expressly authorized by the authorized officer, or otherwise officially approved; (4) Vehicles in official use; and (5) Any combat or combat support vehicle when used in times of national defense emergencies.

RouteSeg (o_csegs) and RouteSpur (rte_spur) do not exist in the trails feature class and therefore are not included in the Route_ID equation for trails. BLM String 110 0 0 ROUTENUM RouteNum The route number provides the identifier for each BLM road and trail. Other agency route numbers should be placed in primary route name (RT_NM1) field. BLM String 35 0 0 FCI_CONDCODE FCI_CondCode This field depicts the overall condition of a trail as measured by the Facility Condition Index (FCI) metric. FCI is defined as the ratio of deferred maintenance/current replacement value. FCI is a critically important ranking factor for trail projects submitted for inclusion in BLM’s 5-year deferred maintenance/capital improvement program. FCI is computed for FAMS inventoried trails only. BLM String 4 0 0 GOOD Good - FCI = 0.00 to 0.05 BLM FAIR Fair - FCI = 0.06 to 0.15 BLM POOR Poor - FCI > 0.15 BLM CONSTRYEAR ConstrYear This field is a record of the construction year (FY) of the route. BLM SmallInteger 2 0 0 MAINTINT MaintInt Maintenance is divided into four intensity levels in accordance with the BLM Manual 9113. The intensity levels provide a progressive system of maintenance with even the lowest intensity level ensuring resource protection by controlling surface erosion and sedimentation. Maintenance intensities provide consistent objectives and standards for the care and maintenance of BLM roads based on identified management objectives. Maintenance intensities provide operational guidance to field personnel on the appropriate intensity, frequency, and type of maintenance activities that should be undertaken to keep the road in acceptable condition and provide guidance for the minimum standards of care for the annual maintenance of a road. Western Oregon guidance has been included to assist the reader in determining an appropriate maintenance intensity level for each BLM owned road. Roads functionally classified as resource roads may receive more extensive maintenance during periods of increased administrative or commercial use. The benefitting activity or user (BLM timber sale purchaser or permittee) may be responsible for funding the maintenance work required for their use. Lack of funding or short-term increases in maintenance shall not be considered when assigning long-term maintenance intensity levels. Roads not owned by the BLM, which were constructed on BLM lands under right-of-way grants or permits will be maintained in accordance with the terms of the grant or permit. Maintenance Intensity Levels and descriptions are provided below: Intensity Level 0 Maintenance Description: Existing routes that will no longer be maintained and no longer be declared a route. Routes identified as Level 0 are identified for removal from the Transportation System entirely. Maintenance Objectives: • No planned annual maintenance. • Meet identified environmental needs. • No preventative maintenance or planned annual maintenance activities. Maintenance Funds: No annual maintenance funds. Western Oregon Guidance: The objective of this maintenance intensity level should include road segments currently closed to vehicles that may be used again in the future. This will facilitate assigning decommissioned roads at this level. Roads in storage should be assigned this maintenance intensity level. Intensity Level 1 Maintenance Description: Routes where minimum (low intensity) maintenance is required to protect adjacent lands and resource values. These roads may be impassable for extended periods of time. Maintenance Objectives: • Low (Minimal) maintenance intensity. • Emphasis is given to maintaining drainage and runoff patterns as needed to protect adjacent lands. Grading, brushing, or slide removal is not performed unless route bed drainage is being adversely affected, causing erosion. • Meets identified resource management objectives. • Perform maintenance as necessary to protect adjacent lands and resource values. • No preventative maintenance. • Planned maintenance activities limited to environmental and resource protection. • Route surface and other physical features are not maintained for regular traffic. Maintenance Funds: Maintenance funds provided to address environmental and resource protection requirements. No maintenance funds provided to perform preventative maintenance. Western Oregon Guidance: Traffic is generally administrative with some minor specialized use or moderate seasonal use. These are typically low standard, low volume, single lane, natural or aggregate surfaced logging spurs, functionally classified as resource roads. These roads will be the third priority for expending both annual (6252) and collected (9110) maintenance funding each year. Storm-proofing will be used to maintain open resource roads found within riparian reserve areas receiving infrequent maintenance. Storm-proofing puts a road into more of a self-maintaining condition and will reduce chronic sediment inputs along stream channels and water-bodies. BMPs for storm-proofing may involve: • Relieving inboard ditches more frequently. • Rocking road surfaces. • Seeding, mulching, and re-vegetating erosion prone surfaces, where sediment delivery to stream channels may result. • Applying site-specific measures to alleviate concentration of road drainage causing erosion and sediment delivery to streams. • Lowering risk of stream diversion potential at stream crossings • Upgrading stream crossings to pass the 100 year flood with allowance for debris and bedload. • Removing or lowering unstable fills. • Outsloping in-sloped ditch roads. • Road drainage control to stabilize dissipation areas. Intensity Level 2 RESERVED FOR POSSIBLE FUTURE USE Intensity Level 3 Maintenance Description: Routes requiring moderate maintenance due to low volume use (for example, seasonally or year-round for commercial, recreational, or administrative access). Maintenance Intensities may not provide year-round access but are intended to generally provide resources appropriate to keep the route in use for the majority of the year. Maintenance Objectives: • Medium (Moderate) maintenance intensity. • Drainage structures will be maintained as needed. Surface maintenance will be conducted to provide a reasonable level of riding comfort at prudent speeds for the route conditions and intended use. Brushing is conducted as needed to improve sight distance when appropriate for management uses. Landslides adversely affecting drainage receive high priority for removal; otherwise, they will be removed on a scheduled basis. • Meets identified environmental needs. • Generally maintained for year-round traffic. • Perform annual maintenance necessary to protect adjacent lands and resource values. • Perform preventative maintenance as required to generally keep the route in acceptable condition. • Planned maintenance activities should include environmental and resource protection efforts, annual route surface. • Route surface and other physical features are maintained for regular traffic. Maintenance Funds: Maintenance funds provided to preserve the route in the current condition; perform planned preventive maintenance activities on a scheduled basis; and address environmental and resource protection requirements. Western Oregon Guidance: These road segments are functionally classified as local roads and serve as a connection to the BLM collector and resource road network. These roads will be the second priority for expending both annual (6252) and collected (9110) maintenance funding each year. Intensity Level 4 RESERVED FOR POSSIBLE FUTURE USE Intensity Level 5 Maintenance Description: Route for high (maximum) maintenance due to year-round needs, high volume of traffic, or significant use. Also, may include route identified through management objectives as requiring high intensities of maintenance or to be maintained open on a year-round basis. Maintenance Objectives: • High (Maximum) maintenance intensity. • The entire route will be maintained at least annually. Problems will be repaired as discovered. These routes may be closed or have limited access due to weather conditions but are generally intended for year-round use. • Meets identified environmental needs. • Generally maintained for year-round traffic. • Perform annual maintenance necessary to protect adjacent lands and resource values. • Perform preventative maintenance as required to generally keep the route in acceptable condition. • Planned maintenance activities should include environmental and resource protection efforts, annual route surface. • Route surface and other physical features are maintained for regular traffic. Maintenance Funds: Maintenance funds provided to preserve the route in the current condition; perform planned preventative maintenance activities on a scheduled basis; and address environmental and resource protection requirements. Western Oregon Guidance: These road segments generally link the state and county arterial road network with BLM’s local road network and are functionally classified as collector roads. These roads will be the first priority for expending both annual (6252) and collected (9110) maintenance funding each year.

Definitions used are from the Western Oregon Transportation Management Plan document. Level 1: These trails are closed to motorized and non-motorized use. This level is the minimum maintenance required protecting adjacent lands and resource values. The objective is to remove these trails from the trail system. Level 2: Low use trail with little or no contact between parties. There is little or no monitoring or management of visitor use. Visitors may encounter obstructions like brush and deadfall. Level 3: Moderate use trail with visitor use on a seasonal and/or peak use period with frequent contact between parties. Trail management is conducted with occasional monitoring or management of visitor use. Visitors are not likely to encounter obstructions. Level 4: High use trail used during specific times of the year with high frequencies of contact between parties. These trails have regularly scheduled monitoring or management of visitor use. Level 5: A special high use trail with routine monitoring or management of visitor use.

Capital improvement does not change road ownership. Capital improvements include work and materials expended to better a road by increasing its construction standard when compared to its original construction standard. Examples of capital improvements include widening and/or surfacing the roadway, adding drainage structures, and replacing bridges.

BLM Double 8 0 0 BLMORGCODE BLMOrgCode A combination of the BLM administrative state and field office that has administrative responsibility for the spatial entity. This includes determining the office to cover the entity for planning purposes and the office that is the lead for GIS edits. Another agency or individual may have the physical management responsibility for the on-the-ground entity. This field applies particularly when a spatial entity crosses field office or district boundaries and the administrative responsibility is assigned to one or the other rather than splitting the spatial unit. Similarly, OR/WA BLM may have administrative responsibility over some area that is physically located in Nevada, Idaho, or California and vice versa. When appropriate, identify the office to the district or even the state level rather than to the field office level. BLM String 5 0 0 Administrative Unit Organization Code.

It may eventually link GTRN features to the 2000 TIGER data. BLM String 9 0 0 ACCURACYFT AccuracyFt How close, in feet, the spatial GIS depiction is to the actual location on the ground. There are several factors to consider in GIS error: scale and accuracy of map-based sources, accuracy of Global Positioning System (GPS) equipment, and the skill level of the data manipulators. A value of “0” indicates no entry was made. This is the correct value when the COORD_SRC is another GIS theme (Digital Line Graph, Cadastral National Spatial Data Infrastructure and Digital Elevation Model (DEM)) because the accuracy is determined by that theme. However, if COORD_SRC is MAP (digitized from a paper map) or GPS, a value of “0” indicates a missing value that should be filled in either with a non-zero number or “-1.” A value of “-1” indicates that the accuracy is unknown, and no reliable estimate can be made.
