The Bureau of Land Management’s (BLM) transportation system represents one 

of the most critical assets in the accomplishment of the BLM’s mission to manage 

public lands. It affords entry for public access and provides the infrastructure that 

supports uses ranging from recreation to commercial activity and is the primary 

means of access to the 261.8 million acres under BLM jurisdiction.

Requirements associated with the effective stewardship of public lands, such as 

the Government Performance and Results Act, Federal Accounting Standards 

Advisory Board, Federal Land Policy and Management Act, and Off-Road 

Vehicle Executive Orders, continue to focus expectations internally and externally 

on a coordinated, consistent, and cohesive approach to the management of 

transportation-related linear features—generically referred to as routes—on 

public lands. The rationale for this effort is that the broad effect of the 

transportation system across the BLM’s missions, strategic goals, and programs 

makes a consistent, organization-wide approach, rooted in common terms and 

definitions, an essential part of the management of public lands.

Several terms are used in reference to roads and trails on BLM lands. For 

purposes of this report, the term “linear features” has been used to describe 

transportation system-related “features,” from engineered roadways with asphalt 

surfaces through challenging trails accessible only to nonmotorized traffic; “linear 

features” includes designated and nondesignated assets. The implementation 

of the Facility Asset Management System (FAMS) highlighted the need for a 

standard lexicon.

Access to public lands is crucial for the effective use and stewardship of those 

lands. The Bureau of Land Management’s (BLM) extensive transportation system 

provides the basis for access to the BLM’s 261.8 million acres and supports all of 

the BLM’s Strategic Goals as the “backbone” for administrative, commercial, and 

recreational use.

Because of the wide range of needs and uses, the BLM’s routes represent a broad 

spectrum of linear features—from engineered roadways with asphalt surfaces 

through challenging trails accessible only to nonmotorized traffic. Inherent in the 

wide range of uses and “customers” is a varied vocabulary used to describe the 

linear features that includes roads, trails, paths, routes, and a host of derivatives 

of the basic terms. All of these terms have meaning and context within their 

respective programs but, when used collectively, often conflict and lead to 

confusion caused by the use of the same term to describe very different physical 

features.

The development of a consistent set of terms and definitions for use across 

the BLM is an essential first step to comprehensive travel management. By 

establishing a common set of terms and definitions, the foundation is established 

for effective interchange of management needs and information within and across 

programs. Standard terms and definitions also allow the BLM to communicate 

efficiently and consistently with customers and stakeholders.

The Roads and Trails Terminology Team was chartered to “establish strategic 

direction and consistent terminology used by the recreation, planning, National 

Science and Technology Center (NSTC), National Landscape Conservation 

System (NLCS), lands, property, and engineering groups to manage the BLM 

transportation system in activities such as planning, inventorying, designating, 

mapping, signing, monitoring, developing public information, maintaining, 

assessing condition, tracking, and reporting data so ongoing alignment of current 

and future strategic comprehensive travel management and transportation 

objectives can be achieved.” The present report represents the results of that effort 

and provides analysis, findings, and recommendations that address the key issues 

identified within the Team’s charter (provided as Attachment 1).

The Roads and Trails Terminology Team (see Attachment 2 for a list of Team 

members), a joint effort between the National Recreation and Visitor Services 

Group, WO-250 (Recreation) and Protection and Response Group, WO-360 

(Engineering) within the BLM, was formed to address critical issues surrounding the BLM approach to management of transportation linear features (such as 

routes, roads, trails, and paths). The issues included developing organization-wide 

approaches to:

1. Establishing standard terms and definitions for the management of the 

BLM’s linear assets that consistently identify, categorize, and track linear 

features that occur on the BLM’s land, as well as those terms used to describe 

appropriate levels of stewardship to manage, protect, and preserve the 

public’s assets.

2. Developing processes for collection, storage, and management of 

data used to manage public lands and associated transportation system to 

include linear features identified for removal or reclamation, as well as those 

designated as part of the BLM’s transportation system.

3. Establishing a national data dictionary for all BLM roads, trails, and 

related items that provides the basis for consistency across the BLM in the 

management of data associated with linear features. 

4. Aligning the various programs responsible for travel management 

functions in a parallel fashion through the use of consistent terminology for 

conducting inventories, assessments, plans, monitoring, and other program 

functions. 

The Team’s approach to addressing these objectives included a combination of 

core team members and “advisors” (for a list of advisors, see Attachment 3) that 

represented the BLM’s programs and allowed the Team to develop a comprehensive travel management approach suited to all the BLM’s program needs. The 

Team, once engaged, realized a need to combine two of these objectives, as the 

data dictionary component relates to the collection, storage, and management of 

data. The result provided three objectives:

 N o v e m b e r 2 0 0 6 Te c h n i c a l N o t e 4 2 2

R O A D S A N D T R A I L S T E R M I N O L O G Y

Objective 1. Establish Bureau Definitions and Standards for Transportation Linear 

Features

Objective 2. Determine Appropriate Minimum National Data Standards and 

Electronic Storage Location for Linear Feature Data (the integration of 

original objectives 2 and 3);

Objective 3. Develop a Strategy to Align the Inventory and Management of 

Transportation Linear Features between Resource Management 

Programs (formerly objective 4).

The process used to address the three objectives incorporated three steps:

• Understanding

• Analysis

• Findings and Recommendations

Through facilitated discussions within the core group and the advisors, each identified issue 

was reviewed to develop a clear understanding of the problem that included:

• Evaluation of the issue statement to define necessary outcomes and resolutions to 

achieve success

• Breadth of impact (programs affected, relations to non-BLM organizations, and legal 

or policy implications)

• Stakeholders

The Team’s analysis of each issue included research into similar approaches taken by other 

Federal, State, and local agencies, as well as applicable private sector strategies, development 

of recommended approaches for consideration by the Team, and then vetting of those 

potential approaches within the Team and the advisor group to develop the Team’s findings 

and recommendations for each established issue.

For clarity and a consistent understanding of the report’s findings and recommendations, the 

following terms were established by the Roads and Trails Terminology Team:

• Transportation Linear Features—“Linear features” represents the broadest category 

of physical disturbance (planned and unplanned) on BLM land. Transportationrelated linear features include engineered roads and trails, as well as user-defined, 

nonengineered roads and trails created as a result of the public use of BLM land. 
Te c h n i c a l N o t e 4 2 2 N o v e m b e r 2 0 0 6 

R O A D S A N D T R A I L S T E R M I N O L O G Y

Linear features may include roads and trails identified for closure or removal, as well as 

those that make up the BLM’s defined transportation system.

• Transportation System—The “transportation system” represents the sum of the 

BLM’s recognized inventory of linear features (roads, primitive roads, and trails) 

formally recognized, designated, and approved as part of the BLM’s transportation 

system.

• Routes—“Routes” represents a group or set of roads, trails, and primitive roads 

that represents less than 100% of the BLM transportation system. Generically, 

components of the transportation system are described as routes.

• Roads, Trails, and Primitive Roads—These terms describe specific categories of 

transportation linear features and represent subsets of the BLM’s transportation 

system.

• Transportation Linear Disturbances—“Linear disturbances” is used to identify 

human-made linear features that are not part of the BLM’s transportation system. 

Linear disturbances may include engineered (planned) as well as unplanned single and 

two-track linear features that are not part of the BLM’s transportation system.

The use of consistent terminology is at the heart of many of the issues identified by the 

Roads and Trails Terminology Team. The Proposed Comprehensive Travel Management 

Terminology Hierarchy (Figure 1) provides an organizational context for the linear features 

that exist on BLM land. Generally, those linear features are described in two categories: 

transportation system and transportation linear disturbances representing the human-made 

linear features that are not part of the transportation system.

Figure 1. Proposed Comprehensive Travel Management Terminology Hierarchy.

Findings and recommendations were developed from the Team’s research, analysis, and 

deliberation to address the identified issues. Findings were generally developed as a result 

of the Team’s efforts to understand and “quantify” the issue, while the recommendations 

represent the culmination of the Team’s research and analysis to develop suggested 

resolutions.

Detailed approaches in support of several of the recommendations were also developed by 

the Team for issues such as minimum national data standards and recommended definitions.

Additionally, some recommendations require development of an implementation plan, 

policy directives, or other related follow-up actions, including proposed “Action Plans” with 

preliminary schedules, responsibilities, and objectives.

Linear Features

Understanding

The Bureau of Land Management presently manages more than 82,000 

miles of road and more than 16,000 miles of trail within the Facility Asset 

Management System (FAMS) that combine to traverse the BLM’s 261.8 

million acres of land. Many other miles of transportation-related linear 

features exist, yet are not actively managed.

A common lexicon and understanding of terms, definitions, and standards 

associated with the identification, description, and categorization of linear 

assets is essential to the effective communication and management of the 

BLM’s assets. Common terms provide a wide range of benefits, including:

• Reasonable categorization and detail in the way the BLM identifies and 

describes its transportation assets.

• Consistent reporting to internal and external stakeholders and customers 

with respect to the size, type, quantity, designation, and use of the BLM’s 

transportation assets.

• Auditable management strategies and asset inventories

Collectively consistent standards and definitions provide the basis for 

clear coordination and communication in the management of the BLM’s 

transportation assets.

Analysis

Definitions and standards presently used to define and describe the BLM’s 

transportation assets are contained within a myriad of documents, including 

BLM Recreation Manuals, Land-Use Planning Manuals, Engineering 

Manuals, Software System Manuals, Federal Regulations, and internal 

policy and guidance documents. Attachment 4 provides a list of the major 

documents reviewed by the Team.

Additionally, existing executive orders, laws, and statutory, regulatory, and 

policy guidance provide a framework within which many of the definitions 

and standards are required to function.

To clarify the problem, the Team conducted three, multiday workshops (in Phoenix, 

Sacramento, and Portland) in which the personnel present (core team and advisors) 

identified the types and characteristics of linear features that create the greatest challenges 

in consistency.

Pictures of existing BLM transportation linear features were used for the exercises that 

allowed each participant to identify and classify a common set of 20 photos (Attachment 

12 contains the initial set of photos).

The results of the exercises indicated that the Team was relatively consistent in classifying 

engineered, low-clearance vehicle linear features as roads and single-track, linear features 

as trails, but was inconsistent in classifying two-track linear features.

Further analysis by the Team identified a common “disconnect” for those linear features 

that are not generally suited for low-clearance vehicular traffic, but which support 

4 × 4 and high-clearance vehicle use. The following diagram (Figure 2) illustrates the 

type of transportation linear features (highlighted) that were identified as the source of 

confusion.

Roads and trails are presently identified and defined in a number of BLM manuals and 

publications, yet none of those definitions seems to provide sufficient clarity to allow 

either the Team or BLM field personnel to classify transportation system linear assets 

consistently.

Research into common practices by other agencies, as well as State and local 

governments, identified “primitive roads” as a third category of routes presently used 

by a number of organizations to describe high-clearance and 4 × 4 routes that are not 

designed to an engineering standard, but are available for use and should be identified 

on transportation systems. Attachment 4 contains a list of documents that includes 

references to similar uses within State and local governments.

An exercise was undertaken by the Team with the representative photos of BLM routes 

to determine whether the introduction of a third asset category identified as “primitive 

roads” would provide sufficient delineation and address the needs of BLM programs. 

The results of that effort, as well as subsequent discussions with the Roads and Trails 

Terminology Team Advisors, indicated strong understanding and support for the 

introduction of the third asset classification.

The Team then developed a set of three basic definitions that describe a road, primitive 

road, and trail for use in categorizing BLM linear features that are part of the BLM’s 

transportation system. Basic definitions for a road and primitive road were developed 

according to the BLM’s 9100 Engineering Manual and the definition for a trail was 

developed from the Interagency Trail Data Standards.

The proposed standard terms and definitions were then reviewed against existing 

documents, known business rules, and identified requirements. On the basis of the 

review, potential issues and required actions were identified and addressed to ensure that 

the resulting definitions provide clear guidance and direction for the identification and 

classification of linear features that compose the BLM’s transportation system.

Existing maintenance levels were also reviewed in conjunction with the development 

of the new asset categories for linear features. The Team’s evaluation of the use of 

Maintenance Levels within the BLM also revealed inconsistent understanding and 

application of the present standards. In many instances, Maintenance Levels were poorly 
10 N o v e m b e r 2 0 0 6 Te c h n i c a l N o t e 4 2 2

R O A D S A N D T R A I L S T E R M I N O L O G Y

understood by field personnel and seemed to be mainly used to describe the type of 

linear feature (e.g., Maintenance Level 2 generally described a high-clearance or 4 × 4 

accessible road) rather than the actual maintenance strategy or intensity determined by 

BLM management as being appropriate to the route.

To address this issue, the Team developed a recommendation to change Maintenance 

Levels to Maintenance Intensities and develop a consistent standard for use across all 

linear features.

Conclusions and Recommendations

1. Standard Terms for Linear Features are based on three asset categories: “Road,” 

“Primitive Road,” and “Trail.”

Finding—The BLM’s “transportation system” includes a broad range of linear assets 

well beyond those presently identified as “roads” and “trails” within the BLM inventory. 

BLM definitions presently used to identify and describe the BLM’s linear assets 

vary within and across existing guidance documents. BLM definitions for defining, 

describing, and categorizing linear assets seem to provide insufficient guidance to 

existing personnel and allow for multiple interpretations that degrade the consistency 

of the BLM’s inventory and reporting process. The Team concluded that reasonable, 

consistent, and auditable results are only achievable by institutionalizing a consistent set 

of terms and definitions across the BLM.

Recommendation—Standardize the terms used as primary categories of transportation 

assets within the BLM as “Road,” “Primitive Road,” and “Trail.” Existing definitions 

for road and trail seem to provide inconsistent guidance for those linear assets that allow 

for motorized traffic of high-clearance vehicles but do not support low-clearance vehicles 

or use clear design standards. Descriptions and standards for describing and classifying 

these assets seem to allow the greatest level of inconsistency. Recommended definitions 

are:

• Road: A linear route declared a road by the owner, managed for use by low-clearance 

vehicles having four or more wheels, and maintained for regular and continuous use. 

• Primitive Road: A linear route managed for use by four-wheel drive or highclearance vehicles. Primitive roads do not normally meet any BLM road design 

standards.

R O A D S A N D T R A I L S T E R M I N O L O G Y

• Trail: A linear 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 addition of a third major classification category (primitive roads) for linear assets 

is viewed by the Team as a key recommendation. Attachment 5 provides the Team’s 

recommendations for an initial set of terms and definitions for use across all programs 

within the BLM when identifying, describing, or categorizing transportation assets.

2. Change “Maintenance Levels” to “Maintenance Intensity” and simplify the 

standards for consistency across all linear features.

Finding—Existing Maintenance Level definitions presently address both the type 

of road (road geometry or construction material) and the level of use but do not 

provide a clear standard for the actual maintenance level. As a result, they are used 

inconsistently across the BLM as a means for describing everything from road 

construction type through appropriate maintenance standards.

Recommendation—Change “Maintenance Levels” to “Maintenance Intensity” and 

simplify the standards for consistency across all linear features. The implementation of 

primary transportation asset categories provides an opportunity to review and enhance 

current standards for determining maintenance levels, managed use standards, and 

other descriptive information used to describe and report on the BLM’s assets. 

Attachment 5 provides the Team’s recommendations for the new Maintenance 

Intensity levels. It includes four primary Maintenance Intensity levels that allow for 

removal, low, medium, and high maintenance intensities, irrespective of the type of 

route (road, primitive road, or trail).

A draft Action Plan with recommended responsibilities and outcomes to support the 

transition of definitions and maintenance standards is provided as Attachment 6.

Objective 2. Determine Appropriate Minimum National Data Standards 

and Electronic Storage Location for Linear Feature Data

Understanding

Directions provided within Land-Use Plans are an important part of the 

BLM’s strategic approach to stewardship of public lands. An integral component to the development, implementation, and management of the plans 

is an accurate knowledge of the transportation linear features identified on 

the BLM’s 261.8 million acres. Information that describes the transportation 

linear features is presently collected through a myriad of efforts ranging from 

interpretation of aerial photography to field investigation utilizing remote 

sensing (Global Positioning System—GPS) equipment.

Data developed as a result of the management planning efforts are generally 

stored in a Geographical Information System (GIS). States and Field Offices 

presently use their own discretion in determining the appropriate information to collect and where the data will be stored after the planning effort.

Inconsistent standards across Field Offices and States have the potential 

to limit the functionality and long-term value of the data to the BLM, as 

well as affect the interoperability between programs (e.g., Recreation and 

Engineering).

Analysis

Existing references, including the Interagency Trail Data Standards and BLM 

Instruction Memorandum 2004-117, “Minimum National Data Standard 

for Roads,” provide specific guidance on the format and content of linear 

feature data and were used as the baseline for the analysis.

The approach allowed the Team to focus on developing recommendations 

and business rules that align the location and storage of linear feature data 

in an approach consistent with the basic objectives and “customers” of the 

electronic systems (e.g., the Facility Asset Management System [FAMS] 

is the BLM’s electronic system for asset management. Therefore, all asset 

management information should reside in FAMS).

R O A D S A N D T R A I L S T E R M I N O L O G Y

The issue of determining which information should reside in the Facility Asset 

Management System (FAMS) versus the Recreation Management Information System 

(RMIS) or BLM-wide geographical information systems such as the National Integrated 

Land System (NILS) was reviewed to identify the customer for the information, which 

business functions the information supports, and key stakeholders for the information 

(see Attachment 11, Trail Data Standards Cross-Walk).

Linking the “customer” and “business purpose” to the potential information allowed 

the Team to develop a recommended approach for the storage of linear feature data 

and identify information that seemed to be beyond the “business purpose” of current 

national level electronic systems within the BLM.

Conclusions and Recommendations

3. Develop and formalize through policy guidance the required minimum national 

data standard for all transportation linear features that compose the BLM transportation system.

Finding—Present standards such as the “Interagency Trail Data Standards” and the 

Bureau of Land Management IM 2004-117, “Minimum National Data Standard for 

Roads,” provide excellent sources for an organization-wide minimum national standard 

for roads, primitive roads, and trails. However, national-level guidance is not presently 

available for primitive roads and trails that indicates the appropriate minimum national 

data standards (a mandated and consistent set of linear feature data across the BLM), recommended data repository, or party responsible for maintaining all of the transportation 

linear feature data within the Bureau of Land Management.

Recommendation—Develop and formalize through policy guidance the required minimum national data standard for all linear features that compose the BLM transportation 

system. The required minimum national data standard should define the required minimum data standards that must be adhered to by all organizations within the BLM when 

planning, collecting, or managing linear feature data that is part of the BLM’s transportation system. The minimum national data standard would not preclude the collection of 

additional information if deemed necessary, but would provide a consistent set of data 

across the entire BLM. Attachment 7 represents the Team’s recommendation for a minimum national data standard for primitive roads and trails that incorporates data from the 

Interagency Trails Data Standard and existing Instruction Memorandum (IM 2004-117) 

on roads into two consistent requirements.

R O A D S A N D T R A I L S T E R M I N O L O G Y

4. Use the Facility Asset Management System (FAMS) as the system for the 

management of all Bureau of Land Management transportation system assets.

Finding—BLM-wide information technology solutions such as the Facility Asset 

Management System (FAMS), Recreation Management Information System (RMIS), 

and National Integrated Land System (NILS) have each identified or “stated” business 

objectives that define their purpose and role within the Bureau of Land Management. 

Those business objectives or roles also define the appropriate location for the BLM’s 

linear feature information and should serve as the guidance for the correct storage and 

management location for BLM linear feature information. 

Recommendation—Use the Facility Asset Management System (FAMS) as the system 

for the management of all Bureau of Land Management transportation system assets. 

The term “assets” in this context represents linear features that have been formally 

identified (or “designated”) as BLM assets versus the sum of all linear features on 

BLM land. Doing so allows the BLM to use a single set of data and provide consistent 

information internally and externally, as well as enhance efficiency through reduced 

duplication of effort and access to the same data across multiple programs.

5. Develop a Minimum National Data Standard for the Collection of Transportation 

Linear Feature Data during Land-Use Planning and Related Efforts.

Finding—Discussions with the programs engaged in land-use planning indicate a single, 

comprehensive BLM-wide approach to the collection and management of transportation 

linear feature information gathered as part of land-use planning efforts is not presently 

available. Moreover, such a national data standard would provide a consistent means of 

collecting a baseline data set for all linear features identified on BLM land.

Recommendation—Develop a Minimum National Data Standard for transportation 

linear features that incorporates national data requirements from Recreation, NLCS, 

and Engineering and provides a consistent set of guidance to the Field. Collection of 

information beyond the minimum national data standard is left to the discretion of 

the individual States and Field Offices. However, when data elements contained within 

the Interagency Trail Data Standards are used, collection of data should conform to the 

guidance provided in the most recent edition of the Interagency Trail Data Standards.

A draft “Action Plan” with recommended responsibilities and outcomes to support the 

implementation and standardization of minimum national data standards for all linear 

features included in the BLM asset inventory, as well as the broad-based use of the 

Facility Asset Management System across the BLM, is provided as Attachment 8.
Objective 3. Develop a Strategy to Align the Inventory and Management 

of Transportation Linear Features between Resource Management 

Programs

Understanding

Transportation linear features on BLM Lands compose one of the most 

significant issues facing the BLM and are the focus of a concentrated 

investment of BLM resources to adequately identify, categorize, designate, 

operate, and maintain. A comprehensive framework that identifies the 

relations, responsibilities, and interconnectivity between the various efforts is 

an essential element to the immediate and long-term objectives of the BLM’s 

planning efforts.

Analysis

The Roads and Trails Terminology Team identified current efforts within the 

BLM that affect the management of linear features. Some of the programs 

that are directly engaged in those types of activities include:

• Recreation

• Engineering

• Minerals (Energy Development)

• Lands and Realty

• Wild Horse and Burro

• Budget and Performance

• National Science and Technology Center

• National Landscape Conservation System

• Fire

• Wildlife

Defining the roles of each organization and how management decisions are 

communicated, incorporated, maintained, and enforced is at the crux of an 

articulated comprehensive framework between the various activities.

The Team’s findings with respect to the alignment between land-use 

planning and asset management highlight some of the specific issues and 

needs that surround the interrelations between land-use planning and the 

resource management of the BLM’s transportation system.

R O A D S A N D T R A I L S T E R M I N O L O G Y

Transportation linear features that exist on public lands are identified on a wide range 

of sources, from the BLM’s internal databases through third-party publications, and the 

quantity, use, and location of those linear features may vary greatly depending on the 

sources. Such a range of sources complicates the effective communication of information 

and makes it difficult to accurately report on the BLM’s inventory of roads, primitive 

roads, and trails.

Additionally, planning efforts associated with land and resource use represent a 

significant investment by the BLM in developing guidance and direction for the 

short- and long-term management of public lands. Given the level of investment and 

effort associated with completing the land-use plans, it is essential that the information 

and decisions they contain be preserved and implemented as part of the BLM’s asset 

management program.

Finally, an integral part of asset management is an approach for modification, 

decommissioning, reclamation, or removal of transportation linear features that no 

longer meet the BLM’s management objectives.

Conclusions and Recommendations

6. Recognize the Facility Asset Management System (FAMS) inventory of routes as the 

BLM’s current transportation system. 

Finding—The BLM does not have a BLM-wide standard for what constitutes 

the current recognized transportation system. While various programs within the 

BLM provide data and maps that depict the BLM’s transportation system, no single 

organization or data system is identified as the “standard” within the BLM. As a result, 

projections and reports of the total miles within the BLM’s transportation system vary 

significantly depending on the source of information and cause the BLM challenges in 

addressing annual financial audit, Government Performance and Results Act, and other 

reporting requirements.

Recommendation—Recognize the Facility Asset Management System (FAMS) as the 

initial inventory of the BLM’s transportation system. FAMS presently contains 82,000 

miles of road and 16,000 miles of trails that are used to report the BLM’s asset inventory 

and deferred maintenance requirements and develop annual maintenance needs. FAMS

R O A D S A N D T R A I L S T E R M I N O L O G Y

represents the “baseline” for the BLM’s current transportation system and comprises the 

designated roads and trails within the BLM. Formal recognition of FAMS as the baseline 

will provide consistency between all BLM Programs.

7. Implement a BLM-wide policy that requires any change in the BLM’s inventory of 

designated roads, primitive roads, and trails to occur through the land-use planning process.

Finding—A BLM-wide policy that provides management controls on changes to 

the designated inventory of routes within the BLM’s transportation system operates 

informally but does not exist as part of formal guidance or policy.

Recommendation—Implement a BLM-wide policy that requires any change in the 

BLM’s designated transportation system to occur through the land-use planning process. 

Changes to the BLM’s designated transportation system should occur as part of the 

formal evaluation and designation process through one of four events:

• Record of Decision (ROD) for a Resource Management Plan/Environmental Impact 

Statement (RMP/EIS) or an Amendment or Revision of an RMP/EIS.

• Decision Record for an Activity Plan, Plan Amendment/Environmental Assessment 

(EA).

• Federal Register Notice Action (under the authority of 43 CFR 8341.2, 8364.1, 

8365.1-6, or 9268.3) that has a follow-up land-use planning action and associated 

NEPA action.

• Management decision of appropriate routes in an area that has been designated open 

to off-highway vehicle use.

The recommended approach for implementation of guidance between the land-use 

planning and formalized recognition and management of routes within FAMS is an 

Instruction Memorandum (IM) that clearly identifies the appropriate process for formal 

changes to the BLM’s transportation system asset inventory.

8. Develop a comprehensive travel management policy for land-use planning guidance 

to facilitate a consistent approach and process across the BLM. 

Finding—BLM guidance for transportation-related land-use planning is presently 

contained in a wide range of documents, from BLM manuals through planning 
20 N o v e m b e r 2 0 0 6 Te c h n i c a l N o t e 4 2 2

R O A D S A N D T R A I L S T E R M I N O L O G Y

handbooks. The lack of a single, comprehensive source of guidance contributes to the 

difficulty in providing consistency in the process and its application within the BLM.

Recommendation—Develop comprehensive travel management policy guidance on 

land-use planning to facilitate a consistent approach and process across the BLM. Travel 

planning and management guidance presently exists in a number of locations. Develop 

a BLM comprehensive travel management source guide for use across the BLM that 

provides consistency within the BLM and also minimizes the effort required to maintain 

BLM guidance.

Attachment 9 provides a draft “Action Plan” with recommended responsibilities and 

outcomes to support the standardization of comprehensive travel management planning 

guidance in a source guide.

9. The BLM should develop policy guidance to identify, track, monitor, prioritize, and 

fund the removal of unwanted transportation linear features (routes and other linear 

disturbances on BLM land).

Finding—A BLM-wide approach to addressing transportation linear features identified 

as part of the land-use planning process, but not designated as part of the BLM’s 

transportation system, does not exist. States and Field Offices presently address the issue 

with approaches that range from abandonment through aggressive remediation. Lack of 

a nationwide approach to address the need makes it extremely difficult for the BLM to 

even articulate the full extent of the requirement, let alone proactively resolve it.

Recommendation—The BLM should develop policy guidance and implement a 

formalized approach to identify, track, monitor, prioritize, and fund the removal of 

transportation linear features (routes and other linear disturbances on BLM land).

A formalized approach to the mitigation of existing transportation linear features 

through decommissioning, reclamation, or modification of use is an integral part of 

the implementation of land-use planning efforts. Formalizing the BLM’s approach 

to addressing these needs provides a consistent advocacy for seeking funding through 

internal and external funding sources, developing priorities, and monitoring the progress 

of the BLM’s efforts to implement the land-use plans. A draft “Action Plan” with 

recommended responsibilities and outcomes to support the development of a BLM-wide 

approach to address unwanted linear features is provided as Attachment 10.

Attachment 1. Roads and Trails Terminology Team Charter 

Purpose

The purpose of the Roads and Trails Terminology Team is to establish strategic direction and 

consistent terminology used by the recreation, planning, National Science and Technology 

Center (NSTC), National Landscape Conservation System (NLCS), lands, property, and 

engineering groups to manage the BLM transportation system in activities such as planning, 

inventorying, designating, mapping, signing, monitoring, developing public information, 

maintaining, assessing condition, tracking, and reporting data so ongoing alignment of 

present and future strategic comprehensive travel management and transportation objectives 

can be achieved.

Objectives

Specific objectives of this team effort are to:

1) Establish BLM definitions for the many different types of roads, trails, and other 

associated terms (e.g., maintenance levels) that are used when managing these assets.

2) Determine what information on roads and trails will be stored in the Facility Asset 

Management System (FAMS), as well as in other existing data management systems.

3) Establish a national travel management data dictionary for all roads, trails, and closely 

associated linear feature travel and transportation management terminology.

4) Develop a strategy that aligns the various programs responsible for travel management 

functions in a parallel fashion through the use of consistent terminology for conducting 

inventories, assessments, plans, monitoring, and other program functions. 

Membership

The National Recreation Group representative (WO-250) and National Engineering Group 

representative (WO-360) will co-chair the Team. The Team will consist of a facilitator, note 

taker, and representatives from recreation, planning, NSTC, NLCS, lands, property, and 

engineering groups as core members and advisors. In addition, representatives from the field 

and State level, Recreation Visitor Services Advisory Team, the Engineering Advisory Team, 

as well as others will be included as appropriate. The temporary services of a contractor will 

be employed to assist with meeting note-taking, writing and editing draft reports, finalizing 

reports, printing, and distributing final Team products.

2004.

Deliverables

The final report will be submitted to the Assistant Director, Renewable Resources & 

Planning (AD-200), and Assistant Director, Minerals, Realty & Resources Protection 

(AD-300), by January 30, 2005, and will include:

• An updated list of terminology and definitions along with an interpretation for various 

applications.

• A coordination and integration strategy between FAMS, GIS, and RMIS for roads and 

trails planning and management. 

• A travel management data dictionary for all roads, trails, and associated linear travel and 

transportation structures.

• A strategy to coordinate and merge the roads and trails inventory effort with condition 

assessments of those assets.

• A strategy to merge the inventory of roads and trails with land-use plan and recreation 

databases for the identification, designation, and management of travel management 

networks.

Attachment 5. Terms, Definitions, and Maintenance Intensity Standards

DEFINITIONS:

TRANSPORTATION SYSTEM LINEAR FEATURES (ASSETS):

Road: A linear route declared a road by the owner, managed for use by low-clearance 

vehicles having four or more wheels, and maintained for regular and continuous use.

Primitive Road: A linear route managed for use by four-wheel drive or high-clearance 

vehicles. These routes do not normally meet any BLM road design standards.

Trail: A linear 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.

OTHER TERMS USED IN THIS REPORT:

Assets—Term used to describe roads, primitive roads, and trails that comprise the 

transportation system. Also the general term used to describe all BLM-constructed 

“Assets” contained within the Facility Asset Management System (FAMS).

Closed Area—An area where off-highway vehicle use is prohibited. Use of off-highway 

vehicles in closed areas may be allowed for certain reasons; however, such use shall be 

made only with the approval of the authorized officer.

Comprehensive Travel Management—The proactive interdisciplinary planning, 

on-the-ground management, and administration of travel networks (both motorized 

and nonmotorized) to ensure that public access, natural resources, and regulatory 

needs are considered. It consists of inventory, planning, designation, implementation, 

education, enforcement, monitoring, easement acquisition, mapping and signing, and 

other measures necessary for providing access to public lands for a wide variety of uses 

(including uses for recreational, traditional, casual, agricultural, commercial, educational, 

and other purposes).

Designated Roads and Trails—Specific roads and trails identified by the BLM (or other 

agencies) where some type of motorized vehicle use is appropriate and allowed either 

seasonally or yearlong. (BLM Manual H-1601-1, Land Use Planning Handbook)
Te c h n i c a l N o t e 4 2 2 N o v e m b e r 2 0 0 6 29

R O A D S A N D T R A I L S T E R M I N O L O G Y

Limited Area—An area restricted at certain times, in certain areas, or to certain 

vehicular use. These restrictions may be of any type but can generally be accommodated 

within the following categories: Numbers of vehicles; types of vehicles; time or season 

of vehicle use; permitted or licensed use only; use on existing roads and trails; use on 

designated roads and trails; and other restrictions.

Maintenance Intensities–Transportation System Assets—BLM Route Maintenance 

Intensities provide guidance for appropriate “standards of care” to recognized routes 

within the BLM. Recognized Routes by definition include Roads, Primitive Roads, 

and Trails carried as Assets within the Bureau of Land Management Facility Asset 

Management System (FAMS).

Maintenance Intensities provide consistent objectives and standards for the care 

and maintenance of BLM routes according to identified management objectives. 

Maintenance Intensities are consistent with land-use planning management objectives 

(for example, natural, cultural, recreation setting, and visual). 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 route in 

acceptable condition and provide guidance for the minimum standards of care for the 

annual maintenance of a route.

Maintenance Intensities do not describe route geometry, types of route, types of use, or 

other physical or managerial characteristics of the route. Those items are addressed as 

other descriptive attributes to a route. 

Maintenance Intensities provide a range of objectives and standards, from “identification 

for removal” through frequent and intensive maintenance.

Level 0 Maintenance Description: Existing routes that will no longer be 

maintained or declared as routes. 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 preventive maintenance or planned annual maintenance activities

R O A D S A N D T R A I L S T E R M I N O L O G Y

Maintenance Funds: No annual maintenance funds

Level 1 Maintenance Description: Routes where minimal (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.

• Meet identified resource management objectives

• Perform maintenance as necessary to protect adjacent lands and resource 

values

• No preventive 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 preventive maintenance.

Level 2 RESERVED FOR POSSIBLE FUTURE USE

Level 3 Maintenance Description: Routes requiring moderate maintenance 

because of low-volume use (e.g., 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 for keeping 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 
Te c h n i c a l N o t e 4 2 2 N o v e m b e r 2 0 0 6 31

R O A D S A N D T R A I L S T E R M I N O L O G Y

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.

• Meet identified environmental needs

• Generally maintained for year-round traffic

• Perform annual maintenance necessary to protect adjacent lands and 

resource values

• Perform preventive 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 present condition, perform planned preventive maintenance activities 

on a scheduled basis, and address environmental and resource protection 

requirements.

Level 4 RESERVED FOR POSSIBLE FUTURE USE

Level 5 Maintenance Description: Routes for high (Maximum) maintenance 

because of year-round needs, high-volume traffic, or significant use. Also 

may include routes identified through management objectives as requiring 

high intensities of maintenance or to be maintained open year-round. 

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 because of weather conditions but are generally intended for yearround use.

• Meet identified environmental needs

• Generally maintained for year-round traffic

traffic

Maintenance Funds: Maintenance funds provided to preserve the route in 

the present condition, perform planned preventive maintenance activities 

on a scheduled basis, and address environmental and resource protection 

requirements.

Off-Highway Vehicle (off-road vehicle)—Any motorized vehicle capable of—or 

designated 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 for national defense.

Open Area—An area where all types of vehicle use is permitted at all times, anywhere in 

the area subject to the operating regulations and vehicle standards set forth in 43 CFR 

8341 and 8342.

Transportation Linear Disturbances—Human-made linear features that are not 

part of the BLM’s Transportation System. Linear disturbances may include engineered 

(planned), as well as unplanned single- and two-track linear features.

Transportation Linear Features—The broadest category of physical disturbance 

(planned and unplanned) on BLM land. Transportation-related linear features include 

engineered roads and trails, as well as user-defined, nonengineered roads and trails 

created as a result of the public use of BLM land. May include roads and trails identified 

for closure or removal, as well as those that make up the BLM’s defined transportation 

system.

R O A D S A N D T R A I L S T E R M I N O L O G Y

Transportation Plan—A transportation facility plan shown on forms and maps of all 

existing and planned access routes needed to use, protect, and administer the public 

lands. (Preparation of the transportation plan does not depend on RMPs; but as they are 

completed, the transportation plan should be revised to reflect changes.) (BLM Manual 

9100—Engineering)

Transportation System—The sum of the BLM’s recognized inventory of linear features 

(roads, primitive roads, and trails) formally recognized and approved as part of the 

BLM’s transportation system.

Travel Management Areas—Polygons or delineated areas where a rational approach has 

been taken to classify areas as open, closed, or limited; and where a network of roads, 

trails, ways, and other routes that provide for public access and travel across the planning 

area are identified or designated. All designated travel routes within travel management 

areas should have a clearly identified need and purpose, as well as clearly defined 

activity types, modes of travel, and seasons or time frames for allowable access or other 

limitations (BLM Manual H-1601-1, Land Use Planning Handbook).

Way—Roadlike feature used by vehicles having four or more wheels but not declared 

a road by the owner and which receives no maintenance to guarantee regular and 

continuous use.

Lead: WO-360

Due Date:

Reviewer:

Objective 1, Recommendation 1

1. Objective:

The Objective of this Action Plan is to update the Bureau of Land Management’s 

existing guidance documents (manuals, handbooks, and related publications) so that 

they incorporate the new terms, definitions, and Maintenance Level (Maintenance 

Intensity) guidance developed by the BLM Roads and Trails Terminology Team.

2. Action Plan Tasks:

♦ Initiate after Approval of the Roads and Trails Terminology Report

♦ Assemble team to identify existing guidance documents for revision:

 • BLM 9100 Series Engineering Manuals

 • BLM “Gold Book”

 • BLM land-use planning process and documents

 • Facility Asset Management System (FAMS) data standards

 • Facility Asset Management System (FAMS) Maintenance Level designations

 • Minimum National Data Standard—BLM Roads

 • Condition Assessment Protocols—Roads, Primitive Roads, and Trails

 • BLM Real Property and “Asset” Standards

♦ Update existing documents in accordance with Roads and Trails Terminology 

 Report

♦ Update existing documents published by BLM and provided to customers to

 reflect new designations

3. Responsible Organization(s):

WO-250 and WO-360 are each to assign an individual as “lead” to identify and 

update appropriate guidance. WO-360 is responsible for Engineering and Asset 

Management-related information; WO-250 is to update land-use planning documents.

4. Outcomes:

Consistent terms, definitions, and maintenance needs within the BLM, as well as an 

“alignment” of existing terms and definitions across multiple programs within the 

BLM.

Attachment 8. Action Plan—National Standard for Transportation Linear Features

Bureau of Land Management

Action Plan

Subject: Minimum National Data Standard for Linear Features

Lead: WO-250

Due Date:

Reviewer:

Objective 2, Recommendation 5

1. Objective:

The Objective of this Action Plan is to create a minimum national data standard that 

will form the “baseline” for the collection of linear feature information across the 

BLM and allow for aggregation, analysis, and comparison across Field Offices, States, 

and the BLM.

The BLM does not presently provide guidance or direction on a required minimum 

data standard for collection during the land-use planning process. As a result, 

State and Field Office personnel collect a wide range of data during the linear 

feature inventory process based on an inconsistent set of data standards and naming 

conventions.

This effort is intended to provide guidance and direction to all BLM personnel and 

facilitate a common “baseline” of linear feature information across the BLM. It is not 

intended to preclude BLM personnel from collecting additional information beyond 

the minimum national standard.

2. Action Plan Tasks:

♦ Initiate after Approval of the Roads and Trails Terminology Report

♦ Assemble Team to develop “draft” minimum national data standard for linear 

 features based on existing standards and efforts.

 • National Trails Data Standard

 • IM 2004-117, Minimum National Data Standard Roads

 • National Integrated Land System (NILS) data standards

 • UTAH BLM GIS Data Standards, January 22, 2004.

 • Recreation Information Management System (RMIS) data requirements

♦ Present “draft” minimum national data standards to Recreation Visitor Services 

 Advisory Team (RVSAT) and Engineering Advisory Team (EAT) for concurrence

♦ Provide “draft” minimum national data standards to WO-250 and WO-360 for 

 approval

♦ Publish minimum national data standards for linear features

R O A D S A N D T R A I L S T E R M I N O L O G Y

3. Responsible Organization(s): WO-250 is to provide leadership on the effort and 

coordinate with WO-360 for consistency and the ability to integrate linear feature 

data into FAMS in the event linear features become assets. 

4. Outcomes: Minimum national data standards for all BLM transportation and landuse planning efforts that provide a common baseline while preserving the field’s ability 

to augment the standards to meet location specific requirements.

Attachment 9. Action Plan—Standard Guidance for Land-Use Planning

Bureau of Land Management

Action Plan

Subject: Standardize BLM Comprehensive Travel Management 

Planning Guidance in a Single Source Guide to Provide 

Consistency within BLM

Lead: WO-250

Due Date:

Reviewer:

Objective 3, Recommendation 8

1. Objective:

The Objective of this Action Plan is to bring together and standardize existing 

transportation planning and management guidance in a single location and provide 

a single approach across the BLM that links to other program initiatives and 

requirements.

Travel planning and management guidance is presently contained in several guidance 

documents and does not provide a consistent policy and approach across the BLM. 

The ability for successfully implementing comprehensive travel management 

will enhance the BLM’s consistency, allow for improved communication with 

stakeholders, and provide a more efficient approach to the BLM’s planning efforts.

This effort is intended to provide a common reference and single source of 

information for all land-use planning efforts. 

2. Action Plan Tasks:

♦ Initiate after Approval of the Roads and Trails Terminology Report

♦ Assemble team to identify existing sources of land-use planning guidance

♦ Develop a single standard source guide document for all land-use planning efforts

♦ Publish updated land-use planning document for BLM use

3. Responsible Organization(s): The recommended approach is for WO-250 to 

provide leadership on the effort and coordinate with appropriate BLM programs and 

Divisions as necessary. 

4. Outcomes: The outcome of this effort is a single reference source for all BLM landuse planning that is coordinated with other programs and provides land-use planners 

with a consistent and efficient reference.

Attachment 10. Action Plan—Removal of Transportation Linear Features

Bureau of Land Management

Action Plan

Subject: Develop and Implement a Formalized Approach for 

Tracking and Removal of Unwanted Linear Features on 

BLM Land

Lead: WO-360

Due Date:

Reviewer:

Objective 3, Recommendation 10

1. Objective:

The Objective of this Action Plan is to develop and implement a formal program 

within BLM that identifies, tracks, and prioritizes unwanted linear features (linear 

disturbances and existing roads and trails identified for removal) and develops a 

funding mechanism to support the removal or rehabilitation process without adversely 

affecting existing limited resources used for annual and deferred maintenance.

The BLM does not presently have a formal process or program that identifies, tracks, 

prioritizes, and funds the removal of unwanted linear features. Such a program is 

essential to the long-term asset management of BLM land and is considered essential 

by the Roads and Trails Terminology Team.

This effort is intended to provide a concerted, long-term effort that provides the BLM 

with a consolidated means of reporting the present levels of unwanted linear features 

on BLM land and a means for proactively managing their removal and remediation.

2. Action Plan Tasks:

♦ Initiate after Approval of the Roads and Trails Terminology Report

♦ Develop a team composed of key BLM Stakeholders to formulate a recommended 

 program for implementation within the BLM

♦ Coordinate the effort with existing land-use planning, asset management, and 

 related activities.

♦ Develop a recommended BLM strategy for implementation across the BLM

♦ Staff and Manage the effort on an ongoing basis

3. Responsible Organization(s): The recommended approach is for WO-360 to 

provide leadership on the effort with a combined task team that includes engineering 

and recreation personnel and to coordinate with appropriate BLM programs and 

Divisions as necessary.

to use in identifying, tracking, prioritizing, funding, and removing or rehabilitating 

unwanted linear features on a nationwide basis.
