National Trail Classification System, FSM 2350, and FSH 2309.18

AGENCY: Forest Service, USDA.

ACTION: Notice of proposed policy and directives; request for comment.

-----------------------------------------------------------------------

SUMMARY: The Forest Service is publishing for public notice and comment 
proposed revisions to the agency's national trail classification system 
(TCS), including the Trail Class Matrix and Design Parameters, and 
proposed implementing directives. On May 13, 2005, the Backcountry 
Horsemen of America filed a lawsuit against the Forest Service 
challenging revision of the TCS without public notice and comment. In 
an order dated March 29, 2006, the U.S. District Court found that the 
Forest Service failed to provide public notice and comment as required 
by the National Forest Management Act, 16 U.S.C. 1612. In accordance 
with the Court's order, the Forest Service is publishing the proposed 
revisions to the TCS and proposed implementing directives for public 
notice and comment.

DATES: Comments must be received in writing by September 1, 2006.

ADDRESSES: Send written comments to Jonathan Stephens, National Program 
Manager for Trails and Congressionally Designated Areas, USDA Forest 
Service, Recreation and Heritage Resources Staff, 1400 Independence 
Avenue, SW., Stop 1125, Washington, DC 20250; or by facsimile to 202-
205-1145. Comments also may be submitted by following the instructions 
at the Federal rulemaking portal at https://www.regulations.gov.
    All comments, including names and addresses when provided, will be 
placed in the record and will be available for public inspection and 
copying. The public may inspect comments received on the proposed TCS 
and directives in the USDA Forest Service Headquarters in Washington, 
DC, on business days between 8:30 a.m. and 4:30 p.m. Those wishing to 
inspect comments are encouraged to call ahead at 202-205-1701 to

SUPPLEMENTARY INFORMATION:

1. Background

    The Forest Service is responsible for managing 192 million acres of 
National Forest System (NFS) lands. On these lands, approximately 
133,000 miles of NFS trails are managed by the Forest Service. An NFS 
trail is a forest trail other than a trail which has been authorized by 
a legally documented right-of-way held by a State, county, or other 
local public road authority (36 CFR 212.1). A forest trail is a trail 
wholly or partly within or adjacent to and serving the NFS that the 
Forest Service determines is necessary for the protection, 
administration, and utilization of the NFS and the use and development 
of its resources (36 CFR 212.1). Design, construction, operation, and 
maintenance of NFS trails fall under the authority of Forest and 
Grassland Supervisors.
    In the early 1990s, the Forest Service began developing a new 
information management process and database for inventorying and 
managing NFS trail data. This process included identification of 
national trail classifications and associated physical characteristics 
of trails.

Development of Trail Classes

    Since the mid-1980s, the Forest Service has been concerned that 
there was no system for gathering consistent, comprehensive data on 
real property inventory, facility conditions, program priorities, and 
budget needs for Forest Service resources. Therefore, in 1991, the 
Chief of the Forest Service directed managers of the Forest Service's 
national trails program to develop a system for identifying real 
property inventory, the condition of facilities, and the cost of 
maintaining those facilities to standard and reducing maintenance 
backlogs.
    In 1991, the Forest Service established three categories for 
classifying NFS trails based on their difficulty level. These 
categories, which are enumerated in the Forest Service Handbook (FSH), 
are most difficult, more difficult, and easiest. In addition, since 
1991, the FSH has contained technical guidelines, called trail guides, 
for specific types of uses, including hiking and pack and saddle stock 
use. For each of the three difficulty levels, each trail guide contains 
design, construction, and maintenance guidelines for the physical 
characteristics of trails. The physical characteristics include maximum 
pitch grade and length, clearing width and height, tread width, and 
surface. The difficulty levels in the trail guides encompass trails 
ranging from the least developed, which are typically steep or narrow, 
to the most highly developed, which are typically wide with minimal 
grades.
    Trail management and use were (and still are) based on trail 
management objectives (TMOs), as determined by the applicable land 
management plan, travel management plan, and trail-specific decisions. 
At the same time local managers identified a trail's management and 
use, they identified the applicable difficulty level. Once managers 
determined the applicable trail management and use and difficulty 
level, applicable technical guidelines from the appropriate trail guide 
could be identified.

Development of the National Trail Database

    In 1994, the Forest Service implemented a trails module in 
Infrastructure (Infra), the Forest Service's national database, which 
operated on the agency's Data General (DG) computer system. The DG 
Infra Trails Module provided a national repository for information 
related to the inventory and management of NFS trails. The DG Infra 
Trails Module included numerous trail attributes, including the three 
difficulty levels and three new trail classes roughly based on a 
trail's development scale: Way (minimally developed), secondary (native 
surface with moderate level of development), and mainline (most 
developed). However, these three trail classes did not correlate with 
the difficulty levels in the FSH for categorizing the technical 
guidelines for NFS trails.
    In 1997, the Forest Service adopted Meaningful Measures (MM), a 
spreadsheet system that tracked the condition of agency facilities, 
including trails, and the cost of meeting national standards for those 
facilities. The MM system included spreadsheets with data entry fields 
identifying NFS trails as way, secondary, or mainline, using 
definitions for those classes from the DG Infra Trails Module.

Revision of the DG Infra Trails Module

    In 1994, the Forest Service reconfigured and updated the DG Infra 
Trails Module to a new IBM system providing greater functionality and 
user-friendliness and refined and expanded sets of data attributes. 
Recognizing the inefficiency of having expansive amounts of related but 
unintegrated information, in addition to the mounting confusion in 
terminology, in 1998 the Forest Service identified the need to 
integrate data from the MM system and the IBM Infra Trails Module. The 
agency concluded that providing

[[Page 38023]]

seamless functionality between the Infra Trails Module and the MM 
spreadsheets would greatly improve agency efficiency and data accuracy 
and consistency. Therefore, in 1998, the Forest Service determined that 
a more uniform national trail classification system, applicable to both 
the MM cost data and the Infra trails inventory data, would improve 
information management and make the Infra Trails Module a truly useful 
and effective tool for local trail managers.
    In 1999, the Forest Service transitioned from the three way, 
secondary, and mainline trail classes to five trail classes keyed more 
precisely to the physical characteristics of NFS trails. The Forest 
Service replaced the way, secondary, and mainline data fields in the MM 
spreadsheets with data fields for the five trail classes. The 2000 MM 
User Guide included a matrix of the five trail classes and a set of 
physical characteristics of trails, including tread, immediate 
environs, obstacles, signing, and constructed features. The MM User 
Guide explained that ``[t]he five Trail Management Classes separate 
trails into broad categories which help stratify the Trail System for 
various projects including Infra inventory, Forest Planning Objectives, 
Visitor Information, and helping to establish coefficients for MM 
costing.'' From 1999 to 2001, these five trail classes were 
incorporated nationwide in MM data requirements and costing efforts.
    In 2000, the Forest Service formed the national Trails Development 
Team (TDT) to improve the Infra Trails Module. The primary objectives 
of the TDT were to integrate and build upon trail reference materials 
to enhance trail inventory, tracking of trail condition and needs, and 
accuracy and accountability of trail inventory and costing; to minimize 
confusion and inconsistency in terminology, definitions, and 
interpretation; and to improve the communication, quality, and utility 
of trail data.
    In revising the Infra Trails Module, the TDT refined five concepts 
that are now collectively known as the ``Trail Fundamentals,'' 
including Trail Type, Trail Class, Managed Use, Designed Use, and 
Design Parameters. The Trail Fundamentals provide an updated and more 
effective means for consistently recording and communicating the 
intended design and management guidelines for trail design, 
construction, maintenance, survey, and assessment. This refinement 
clarified the five Trail Classes and their associated terminology, and 
integrated the trail class concept with technical guidelines, called 
Design Parameters, for the design, construction, maintenance, survey, 
and assessment of NFS trails. Relevant facts pertaining to development 
of the Trail Fundamentals follow.
Trail Class
    On June 15, 2001, the 1999 Trail Class Matrix was reformatted and 
refined to include expanded descriptors for each category. Like the 
previous three difficulty levels and 1999 Trail Classes, the 2001 Trail 
Classes range from minimally developed (Trail Class 1) to fully 
developed (Trail Class 5):
    Trail Class 1: Minimal/Undeveloped Trail.
    Trail Class 2: Simple/Minor Development Trail.
    Trail Class 3: Developed/Improved Trail.
    Trail Class 4: Highly Developed Trail.
    Trail Class 5: Fully Developed Trail.
    Each Trail Class has descriptors for the physical characteristics 
of trails, including tread and traffic flow, obstacles, constructed 
features and tread elements, signs, and typical recreational 
environment and experience.
    The 2001 Trail Class Matrix included three sets of additional 
criteria specific to particular types of uses (motorized, snowmobile, 
and water uses), which were applied in addition to the general criteria 
in the five Trail Classes. In 2005, a fourth set of additional criteria 
was added to the Trail Class Matrix for pack and saddle stock use. The 
primary intent of the original sets of additional criteria was to 
address considerations specific to those uses that were not addressed 
by the general criteria. A secondary intent was to indicate the 
applicability of each Trail Class to use types.
    The agency is proposing to remove the four sets of additional 
criteria because they duplicate the user-specific guidance in the 
Design Parameters. The agency is proposing to include a new chart in 
the FSH that shows the relationship between Trail Class and Managed 
Use.
    In addition, attached to the 2001 Trail Class Matrix is a chart 
entitled, ``Trail Operation and Maintenance Considerations.'' While 
these considerations are a useful tool for trail managers, they are not 
part of the 2001 Trail Class Matrix or Design Parameters. Rather, they 
are provided to assist managers in the development of trail 
prescriptions, program management, and trail operation and maintenance. 
The considerations offer a general starting point and will likely be 
adapted locally to reflect site-specific financial limitations and 
applicable district, forest, and regional circumstances. To clarify 
this distinction, the agency is severing this chart from the Trail 
Class Matrix and addressing its context and purpose in Forest Service 
Manual 2353 and FSH 2309.18.
Managed Use
    A Managed Use is a mode of travel that is actively managed and 
appropriate on a trail, considering its design and management. There 
may be more than one Managed Use per trail or trail segment. As 
indicated by use of the word ``actively,'' the term ``Managed Use'' 
reflects a management decision or intent to accommodate a particular 
use through trail design, maintenance, and management. As with the 
previous classification system, the applicable Managed Uses of a trail 
are based on the trail's TMOs. A trail's TMOs are determined by the 
applicable land management plan, travel management plan, and trail-
specific decisions.
    The concepts of Trail Class and Managed Use are interdependent. 
Determining the desired development scale or Trail Class requires 
consideration of the Managed Uses of a trail. Likewise, determining the 
Managed Uses of a trail requires consideration of the development scale 
of the trail. Therefore, the applicable Trail Class is usually 
identified in conjunction with the Managed Uses of a trail.
Designed Use
    The Designed Use is the Managed Use of a trail that requires the 
most demanding design, construction, and maintenance parameters. The 
Designed Use determines which design, construction, and maintenance 
parameters will apply to a trail.
    While there may be more than one Managed Use, there can be only one 
Designed Use per trail or trail segment. For example, if a trail has a 
Managed Use of Hiker/Pedestrian and Pack and Saddle, Pack and Saddle 
would be the Designed Use or design driver because it requires more 
stringent trail design, construction, and maintenance parameters.
    As with the prior classification system, once the Trail Class, 
Managed Uses, and Designed Use are determined for a trail or trail 
segment, the corresponding set of technical guidelines or design 
parameters can be applied.
Design Parameters
    The Design Parameters were released agency-wide in 2004. The Design 
Parameters are the technical guidelines for trail design, construction, 
maintenance, surveying, and assessment, based on Designed Use and

[[Page 38024]]

Trail Class. They reflect the dominant physical criteria that most 
define the geometric shape of a trail, including tread width, surface, 
grade, cross slope, clearing width and height, and turning radius. Some 
of the variables in the Design Parameters identify a specific value, 
while others identify a range of values. In the latter case, managers 
are instructed to narrow the range, selecting the specific value that 
best reflects the TMOs for the trail.
    The Design Parameters do not indicate the types of uses that can 
occur or are allowed on NFS trails, but rather establish general 
guidelines for the design, construction, maintenance, survey, and 
assessment of NFS trails, based on their physical characteristics and 
Designed Use, as determined by preexisting management decisions. All 
non-motorized uses are allowed on any NFS trail unless specifically 
prohibited (motorvehicle use is covered by 36 CFR part 212, subpart B. 
In addition, local deviations from any Design Parameter may be 
established based on trail-specific conditions, topography, or other 
factors, provided that the deviations reflect the general intent of the 
corresponding Trail Class.
    The Forest Service is proposing to replace the trail guides in the 
FSH with the Design Parameters. The proposal would include Design 
Parameters for Hiker/Pedestrian, Pack and Saddle, Bicycle, All-Terrain 
Vehicle (ATV), Motorcycle, Cross-Country Ski, and Snowmobiles. In 
addition, the agency is proposing to remove the barrier-free trail 
guide because it has been superseded by the Forest Service Trail 
Accessibility Guidelines.

2. Need for Proposed Directives

    The Forest Service provides internal direction to field units 
through its Directives System, consisting of the Forest Service Manual 
(FSM) and Forest Service Handbooks (FSH). Directives provide guidance 
to field units in implementing programs established by statute and 
regulation. Forest Service directives establish agency polices for 
delegations of authority, consistent definitions of terms, clear and 
consistent interpretation of regulatory language, and standard 
processes.
    The Forest Service is proposing to revise the FSM and FSH to 
incorporate the national Trail Classes, Design Parameters, and other 
components of the Trail Fundamentals, along with pertinent definitions 
and direction on use of these management concepts. Although the Trail 
Fundamentals are national management concepts, they are applied and 
implemented at the local level.

Summary of Proposed Changes to the Directives

    The Trail Fundamentals--Trail Type, Trail Class, Managed Use, 
Designed Use, and Design Parameters--are the cornerstones for trail 
planning and management. The proposed directives would revise and 
update the definitions in FSM 2353.05 and FSH 2309.18, section 05, to 
include terminology applicable to the Trail Fundamentals. A new section 
in the FSM and FSH would describe the Trail Fundamentals and how they 
should be used for trail planning and management. The proposed 
directives also would provide direction on how the Trail Fundamentals 
should be applied at the local level. In addition, a new chart would be 
included that shows the relationship between Trail Classes and Managed 
Uses. The trail guides would be replaced with the seven sets of Design 
Parameters (Hiker/Pedestrian, Pack and Saddle, Bicycle, All-Terrain 
Vehicle, Motorcycle, Cross-Country Ski, and Snowmobiles). The Trail 
Class Matrix, Trail Class and Managed Use Application Guide, Trail 
Operation and Maintenance Considerations, and Design Parameters would 
be included in the directives as exhibits. Modifications also would be 
made to the FSM and FSH to reflect the direction in the Forest Service 
Trails Accessibility Guidelines (FSTAG). Additional nonsubstantive 
revisions would be made to the FSM and FSH to clarify and to remove 
redundancy.

Section-by-Section Analysis of Proposed Changes

Proposed Changes to FSM 2353

    2353.04g--Forest Supervisors. An additional responsibility for 
Forest Supervisors would be added requiring the use of the five Trail 
Fundamentals (Trail Type, Trail Class, Managed Use, Designed Use, and 
Design Parameters) for the planning, management, and operation of all 
NFS trails.
    2353.05--Definitions. Definitions for the following terms would be 
added alphabetically to FSM 2353.05: Design Parameters, Designed Use, 
Managed Use, Trail Class, Trail Fundamentals, Trail Management 
Objectives, and Trail Type. In addition, the definition for difficulty 
levels would be revised to exclude trails with a Designed Use of Hiker/
Pedestrian because these trails are now addressed in the FSTAG.
    2353.19--Trail Objective. The title of this section would be 
changed to ``Trail Management Objectives.'' This section would be 
modified to incorporate the identification and documentation of TMOs, 
including the five Trail Fundamentals and travel management strategies.
    2353.2--Types of Trails. This section would be renamed, ``Trail 
Fundamentals,'' and would be revised to include direction on 
identifying and applying the five Trail Fundamentals. The content of 
existing FSM 2353.2 would be incorporated into the new sections on 
Managed Use and Designed Use in FSH 2309.18, section 1.4, and the 
reference to trail guides would be replaced with a reference to the 
Design Parameters.
    2353.21--Difficulty Levels. This section would be renumbered FSM 
2353.3, and would be modified to state that trails with a Designed Use 
of Hiker/Pedestrian are addressed in the FSTAG.

Proposed Changes to FSH 2309.18, Trail Management Handbook Zero Code

    05--Definitions. Definitions for the following terms would be added 
alphabetically to section 05: Design Parameters, Designed Use, General 
Forest Area, Managed Use, Maximum Pitch Density, Short Pitch Maximum, 
Target Grade, Trail Class, Trail Fundamentals, Trail Management 
Objectives, and Trail Type.
    The definition for difficulty levels would be modified to exclude 
hiker/pedestrian accessible trail use because accessibility of hiker/
pedestrian trails is addressed in the FSTAG.
    For consistency with current agency terminology, the definition for 
``forest development trail'' would be replaced with the definition for 
``National Forest System trail'' from 36 CFR 212.1. In addition, the 
definition for ``forest trail'' from 36 CFR 212.1 would be added.
    The definition for ``four-wheel drive way'' would be removed 
because it is inconsistent with the definition for ``four-wheel drive 
way'' in FSM 2353.05.
    The definition for ``snow trail'' would be revised and included in 
the definition for Trail Type.

Chapter One

    1.2--Planning Concept. This section would be renamed, ``Planning'', 
and would be amended to address identification and documentation of 
TMOs.
    1.4--Trail Fundamentals. This new section would identify the five 
Trail Fundamentals. Current section 1.4, Analysis Process, would be 
renumbered section 1.5.
    1.41--Trail Types. This new section would address the intent and 
application of Trail Types.
    1.42--Trail Classes. This new section would address the intent and 
application of the Trail Classes and

[[Page 38025]]

would reference a new exhibit in the FSH containing the Trail Class 
Matrix.
    1.42, Exhibit 01--Trail Class Matrix. This new exhibit would 
contain the Trail Class Matrix, which would contain several 
modifications. Nonsubstantive modifications would be made to the 
introductory paragraphs and to footnote 1 to enhance clarity and reduce 
redundancy. Minor, nonsubstantive changes would be made to the text in 
the bulleted item for tread and traffic flow in Trail Class 3 to 
enhance clarity. Footnote 2 would be removed to reduce redundancy, as 
the intent of this footnote is conveyed by the caveats ``often'' and 
``typically'' in the bulleted text for Typical Recreation Environs and 
Experience. The four tables containing additional criteria for pack and 
saddle trails, motorized trails, snow trails, and water trails would be 
removed. The intent of these tables was to provide additional 
descriptors to address substantial differences based on use type that 
are not addressed by the descriptors in the Trail Class Matrix. This 
goal is accomplished more effectively through the Design Parameters, 
which are keyed to use type, and through inclusion of a new exhibit 
called, ``Trail Class and Managed Use Application Guide,'' which is 
described below.
    1.43--Managed Use. This new section would address the intent and 
application of Managed Use and would reference the exhibit containing 
the Trail Class and Managed Use Application Guide.
    1.43, Exhibit 02--Trail Class and Managed Use Application Guide. 
This section would include the Trail Class and Managed Use Application 
Guide. This exhibit would be added to communicate more succinctly and 
effectively the relationship between the Trail Classes and Managed 
Uses, which was one of the objectives of the additional criteria in the 
current Trail Class Matrix that are being removed.
    1.44--Designed Use. This new section would address the intent and 
application of Designed Use.
    1.45--Design Parameters. This new section would address the intent 
and application of the Design Parameters and would reference the 
exhibits for the Design Parameters, which would replace the trail 
guides (currently in exhibits 2.31a through d, 2.32a through b, 2.32d, 
and 2.33a).
    1.54--Opportunities and Constraints. Question number 11 would be 
revised to replace the reference to difficulty levels with a reference 
to Trail Classes. Per the FSTAG, the concept of difficulty levels is no 
longer applicable to trails with a Designed Use of Hiker/Pedestrian.
    1.55--Relation to Existing Facilities. Question number 4 would be 
revised to replace the reference to barrier-free trails with a 
reference to accessible trails in accordance with the FSTAG.
    1.6--Establishment of Priorities and Management Requirements. A 
sentence referencing the Operation and Maintenance Considerations in 
section 1.6, Exhibit 01, would be added to the end of this section.
    1.6, Exhibit 01--Trail Operation and Maintenance Considerations. An 
exhibit entitled, ``Trail Operation and Maintenance Considerations'' 
would be added to section 1.6. This exhibit is based on the Operation 
and Maintenance Considerations that are attached to the current Trail 
Class Matrix. These considerations would be included in a separate 
exhibit from the Trail Class Matrix because they are not part of the 
Trail Class Matrix. Rather, they are merely a reference for trail 
planning, management, operation, and maintenance.
    1.7--Example of Planning Decisions in a Trail Plan. This section 
would be renumbered section 1.8, and would be renamed, ``Considerations 
for Trail Planning''. The four examples provided in this section would 
be revised to include the concepts of Trail Class, Managed Use, and 
Design Use. The third example would be revised to include a snow trail 
only, rather than a snow trail combined with a standard/terra trail.
    1.7, Exhibit 02--Summit District Trail Inventory. This exhibit 
would be removed because it contains management concepts that have been 
replaced by the Trail Fundamentals.

Chapter 2--Trail Development

    2.03--Policy. This section would be revised to incorporate the 
concepts of Managed Use and Designed Use.
    2.21--Trail Management Objectives. This new section would address 
TMOs, including the five Trail Fundamentals.
    2.22--Difficulty Levels. This section would be replaced with the 
Trail Classes being incorporated into the FSM and FSH.
    2.23a--Locations. The title of this section would be changed to 
``Trailhead Location,'' and the content would be modifed to incorporate 
the concepts of development scale and Trail Class. Additionally, this 
section would be revised to reflect current accessibility guidelines.
    2.23b--Parking. The title of this section would be changed to 
``Trailhead Parking,'' and a statement would be added to reflect 
requirements for compliance with the FSTAG.
    2.23c--Pack and Saddle Stock. The title of this section would be 
changed to ``Pack and Saddle Stock Trailheads.''
    2.23d--Barrier Free Design. This section would be renamed, 
``Application of Forest Service Trail Accessibility Guidelines,'' and 
redesignated section 2.23e. The content would be revised because the 
current text has been superseded by the FSTAG.
    2.23e--Snow Removal. This section would be renamed, ``Snow Removal 
at Trailheads,'' and renumbered section 2.23d.
    2.24--Accessibility for Facilities and Associated Constructed 
Features Along Trails. This new section would address compliance with 
accessibility guidelines for facilities and associated constructed 
features along trails.
    2.24--Wilderness Considerations. This section would be renumbered 
section 2.25. The phrase in paragraph 8 would be replaced with the 
phrase, ``to provide trail treads that do not exceed the tread widths 
identified for wilderness areas in the Design Parameters. ''
    2.3--Trail Construction and Maintenance Guides. This section would 
be renamed, ``Design Parameters.'' A statement regarding the intent and 
application of the Design Parameters would be added. The Design 
Parameters would be listed in the order presented in the following 
sections. A reference to Managed Use and Designed Use would be added in 
the first sentence. The word ``guides'' would be replaced with the 
phrase ``Design Parameters.''
    2.31--Non-Motorized Trails. This section would be renamed, 
``Standard/Terra Non-Motorized Trails.''
    2.31--Hiker Trail Guide. This section would be renamed, ``Hiker/
Pedestrian Design Parameters.'' Paragraph 1, ``Design and Location 
Considerations,'' would be revised to incorporate the concepts of 
Hiker/Pedestrian Designed Use, Managed Use, and Design Parameters. In 
the last paragraph, the phrase, ``mountaineering scramble trails'' 
would be replaced with the phrase, ``mountaineering scramble routes.'' 
In the next sentence, ``trails'' would be replaced with ``routes'' and 
``hiker trail category'' would be replaced with ``Hiker/Pedestrian 
category.''
    2.31a, Exhibit 01--Hiker Trail Guide. This exhibit would be revised 
and renamed, ``Hiker/Pedestrian Design Parameters.'' The following 
changes would be made to this exhibit and all other Design Parameter 
exhibits.
    Nonsubstantive changes would be made to the introductory 
paragraphs,

[[Page 38026]]

bulleted text, and footnotes to enhance clarity and reduce redundancy. 
``Target Range'' would be renamed ``Target Grade'' to clarify the 
intent of this trail characteristic. The values for Target Grade would 
be preceded by ``less than or equal to,'' rather than ``less than,'' to 
reflect more clearly and accurately the continuum of Trail Classes. 
Definitions would be added as footnotes for ``target grade,'' ``short 
pitch maximum,'' and ``maximum pitch density.''
    In addition, the value for short pitch maximum in Trail Class 5 
would be preceded by ``less than or equal to'' and the value for 
clearing height in Trail Class 5 would be preceded by ``more than or 
equal to,'' so as to reflect more accurately the maximum or minimum 
tolerance identified for accessible Hiker/Pedestrian trails in the 
FSTAG.
    2.31b--Pack and Saddle Trail Guide. This section would be renamed, 
``Pack and Saddle Design Parameter,'' The last sentence in paragraph 1, 
``Design and Location Considerations,'' would be replaced with the 
sentence, ``For minimum bridge widths and railing heights, refer to FSH 
7709.56b, section 7.69, exhibit 01, Trail Bridge Design Criteria.''
    2.31b, Exhibit 01--Pack and Saddle Trail Guide. This exhibit would 
be renamed, ``Pack and Saddle Design Parameters'' and would be revised 
as discussed above regarding section 2.31a, exhibit 01.
    2.31c--Mountain Bike. This section would be renamed, ``Bicycle 
Design Parameters.'' The content of this section would be removed, and 
the section would be reserved for updating at a later time.
    2.31c, Exhibit 01--Mountain Bike Trail Guide. This exhibit would be 
renamed, ``Bicycle Design Parameters,'' and would be revised as 
discussed above regarding section 2.31a, exhibit 01. In addition, under 
clearing height for Trail Class 1 and Trail Class 2, the erroneous unit 
of measure of inches would be changed to feet.
    2.31d--Cross Country Ski Trail Guide. This section would be 
renamed, ``Cross-Country Ski Design Parameters,'' and renumbered 2.33a.
    2.32--Motorized Trails. This section would be renamed, ``Standard/
Terra Motorized Trails.''
    2.32a--Bike Trail Guide. This section would be renamed, 
``Motorcycle Design Parameters.'' All references to ``bike'' or 
``biking'' would be replaced with ``motorcycle'' or ``motorcycling.''
    In the introductory text and third and eighth paragraphs of 
paragraph 1, ``Design and Location Considerations,'' ``easiest trails'' 
would be replaced with ``Trail Class 4.'' In the fourth and fifth

3. Regulatory Certifications

Environmental Impact

    Section 31.12, paragraph 2, of FSH 1909.15 (67 FR 54622, August 23, 
2002) excludes from documentation in an environmental assessment or 
environmental impact statement ``rules, regulations, or policies to 
establish Service-wide administrative procedures, program processes, or 
instructions.'' The agency has concluded that the proposed revision of 
the TCS and proposed implementing directives fall within this category 
of actions and that no extraordinary circumstances exist which would 
require preparation of an environmental assessment or environmental 
impact statement (see Back Country Horsemen of America v. Johanns, No. 
05-0960 (ESH) (D.D.C. March 29, 2006), slip op. at 16-18).

Regulatory Impact

    The proposed revision to the TCS and proposed implementing 
directives have been reviewed under USDA procedures and Executive Order 
12866 on regulatory planning and review. The Office of Management and 
Budget (OMB) has determined that the proposed TCS and implementing 
directives are not significant. Accordingly, the proposed TCS and 
implementing directives are not required to be reviewed by OMB.
    Moreover, the proposed TCS and implementing directives have been 
considered in light of the Regulatory Flexibility Act (5 U.S.C. 602 et 
seq.). It has been determined that the proposed TCS and implementing 
directives would not have a significant economic impact on a 
substantial number of small entities as defined by the act because the 
proposed TCS and implementing directives would not impose record-
keeping requirements on them; would not affect their competitive 
position in relation to large entities; and would not affect their cash 
flow, liquidity, or ability to remain in the market. The proposed TCS 
and implementing directives would have no direct effect on small 
businesses.

No Takings Implications

    The proposed TCS and implementing directives have been analyzed in 
accordance with the principles and criteria contained in Executive 
Order 12630. It has been determined that the proposed TCS and 
implementing directives would not pose the risk of a taking of private 
property.

Civil Justice Reform

    The proposed TCS and implementing directives have been reviewed 
under Executive Order 12988 on civil justice reform. After adoption of 
the proposed TCS and implementing directives, (1) all State and local 
laws and regulations that conflict with the proposed TCS and 
implementing directives or that impede their full implementation would 
be preempted; (2) no retroactive effect would be given to the proposed 
TCS and implementing directives; and (3) administrative proceedings 
would not be required before parties could file suit in court 
challenging their provisions.

Unfunded Mandates

    Pursuant to Title II of the Unfunded Mandates Reform Act of 1995 (2 
U.S.C. 1531-1538), which the President signed into law on March 22, 
1995, the agency has assessed the effects of the proposed TCS and 
implementing directives on State, local, and Tribal governments and the 
private sector. The proposed TCS and implementing directives would not 
compel the expenditure of $100 million or more by any State, local, or 
Tribal government or anyone in the private sector. Therefore, a 
statement under section 202 of the act is not required.

Federalism and Consultation and Coordination With Indian Tribal 
Governments

    The agency has considered the proposed TCS and implementing 
directives under the requirements of Executive Order 13132 on 
federalism and has determined that the proposed TCS and implementing 
directives conform with the federalism principles set out in this 
Executive Order; would not impose any compliance costs on the States; 
and would not have substantial direct effects on the States, the 
relationship between the Federal government and the States, or the 
distribution of power and responsibilities among the various levels of 
government. Therefore, the agency has determined that no further 
assessment of federalism implications is necessary.
    Moreover, the proposed TCS and implementing directives would not 
have Tribal implications as defined by Executive Order 13175, 
``Consultation and Coordination with Indian Tribal Governments,'' and 
therefore advance consultation with Tribes is not required.

[[Page 38028]]

Energy Effects

    The proposed TCS and implementing directives have been reviewed 
under Executive Order 13211 of May 18, 2001, ``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use.'' It has been determined that the proposed TCS and implementing 
directives would not constitute a significant energy action as defined 
in the Executive order.

Controlling Paperwork Burdens on the Public

    The proposed TCS and implementing directives do not contain any 
record-keeping or reporting requirements or other information 
collection requirements as defined in 5 CFR part 1320 that are not 
already required by law or not already approved for use. Accordingly, 
the review provisions of the Paperwork Reduction Act of 1995 (
    44 U.S.C. 3501 et seq.) and its implementing regulations at 5 CFR 
part 1320 do not apply.

    Dated: June 26, 2006.
Dale N. Bosworth,
Chief, Forest Service.

Chapter One

1.2--Planning

    1. Many of the general objectives for trails are in the applicable 
land management plan or in more detailed travel management decisions. 
These decisions may lack the detail needed to guide field operations. 
Analyze specific concerns to determine standards for a specific trail 
or trail system, maintenance schedules, funding, management of trail 
use, and priorities for construction and reconstruction.
    2. Recognize the need for more detailed analysis when resource 
conditions change, new recreation opportunities are discovered, 
conflicts among uses arise, or new public issues emerge.
    3. Consider trail management in the context of a land unit. 
Establish and document trail management objectives and associated 
management requirements by examining the interaction of resource 
activities, recreation opportunities, and constraints of the area.
* * * * *

1.4--Trail Fundamentals

    For each National Forest System trail or trail segment, apply the 
Trail Fundamentals in accordance with FSM 2353.2 and FSH 2309.18, 
sections 1.41 through 1.45.

1.41--Trail Types

    1. There are three Trail Types applicable to National Forest System 
trails:
    a. Standard/Terra Trails: Trails which have a surface consisting 
predominantly of the ground, and which are designed and managed to 
accommodate use on that surface.
    b. Snow Trails: Trails, as opposed to winter play areas or other 
areas of concentrated public use, which have a surface consisting 
predominantly of snow or ice, and which are designed and managed to 
accommodate use on that surface.
    c. Water Trails: Trails, as opposed to stretches of whitewater that 
are managed for river-based recreation., which have a surface 
consisting predominantly of water, which are designed and managed to 
accommodate use on that surface, and which may include land-based 
portages.
    2. Trail Types are an inventory convention that allows managers to 
identify trail-specific Design Parameters, management needs, and the 
cost of managing the trail for particular uses or seasons.
    3. There can be only one Trail Type identified per trail or trail 
segment. Identify the applicable Trail Type for each National Forest 
System trail based on applicable land management plan direction, travel 
management plan direction, trail-specific decisions, and other related 
direction.
    4. When there is an overlap in Trail Types (such as, a snow trail 
overlaps a standard/terra trail), inventory the trail under both Trail 
Types in the Infra Trails Module.

1.42--Trail Classes

    1. The five trail classes range from least developed (Trail Class 
1) to most developed (Trail Class 5):
    Trail Class 1: Minimal/Undeveloped Trail.
    Trail Class 2: Simple/Minor Development Trail.
    Trail Class 3: Developed/Improved Trail.
    Trail Class 4: Highly Developed Trail.
    Trail Class 5: Fully Developed Trail.
    2. Trail Classes are an inventory convention used to identify 
applicable Design Parameters and to determine the cost to meet the 
National Quality Standards for trails.
    3. Trail Class descriptors reflect typical attributes of trails in 
each class. Trail-specific exceptions may occur for any Trail Class 
descriptor, provided that the general intent of the corresponding Trail 
Class is retained.
    4. There is a direct relationship between Trail Class and Managed 
Use: one cannot be determined without consideration of the other.
    5. There can be only one Trail Class identified per trail or trail 
segment.
    6. Identify the applicable Trail Class for each National Forest 
System trail or trail segment based on applicable land management plan 
direction, travel management plan direction, trail-specific decisions, 
and other related direction. The appropriate Trail Class should be 
determined at the trail-specific level. Apply the Trail Class that most 
closely matches the trail's TMOs.
    7. See the Trail Class Matrix (FSH 2309.18, sec. 1.42, ex. 01).

[[Page 38032]]

1.43--Managed Use

    1. Managed Use indicates a management intent to accommodate a 
specific use.
    2. The Managed Uses for a trail are usually a small subset of all 
the accepted uses on the trail (i.e., uses that are allowed unless 
specifically prohibited). For example, on a trail that is closed to all 
motorized use, but open to all non-motorized use, the Managed Uses 
could be Hiker/Pedestrian and Pack and Saddle. The accepted uses, 
however, would also include bicycles, llamas, and all other non-
motorized uses.
    3. There can be more than one Managed Use per trail or trail 
segment.
    4. Identify the applicable Managed Use or Managed Uses for each 
National Forest System trail or trail segment based on applicable land 
management plan direction, travel management plan direction, trail-
specific decisions, and other related direction. Develop trails for a 
variety of Managed Uses, such as hiking, horseback riding, and 
motorcycling.
    5. There is a direct relationship between Managed Use and Trail 
Class: one cannot be determined without the other. Not all Trail 
Classes are applicable to all Managed Uses. For guidance on the 
potential applicability of each Trail Class to each Managed Use, see 
FSH 2309.18, section 1.43, exhibit 01, Trail Class and Managed Use 
Application Guide. The combinations presented in this matrix are 
generally applicable agency-wide, although trail-specific exceptions 
may occur.

1.44--Designed Use

    1. There is only one Designed Use per trail or trail segment. 
Although a trail or trail segment may have more than one Managed Use 
and numerous uses may be allowed, only one Managed Use is identified as 
the design driver or Designed Use.
    2. Determine the Designed Use for a trail or trail segment from the 
Managed Uses identified for that trail.

1.45--Design Parameters

    1. Design Parameters reflect the design objective for a trail and 
determine the dominant physical criteria that most define its geometric 
shape. These physical criteria include:
    a. Design Tread Width.
    b. Design Surface, expressed in terms of type and obstacles.
    c. Design Grade, expressed as:
    (1) Target Grade;
    (2) Short Pitch Maximum; and
    (3) Maximum Pitch Density.
    e. Design Cross-Slope, expressed as a target range and maximum.
    f. Design Clearing, expressed as width and height.
    g. Design Turns, expressed as the radius.
    2. Local exceptions to any Design Parameter can be established 
based on specific trail conditions, topography, and other factors, 
provided that the exceptions reflect the general intent of the 
corresponding Trail Class.
    3. The complete set of Design Parameters is contained in section 
2.31a, exhibit 01, through section 2.33b, exhibit 01, of this handbook.
    4. Based on the Trail Class and Designed Use for a National Forest 
System trail or trail segment, identify the applicable Design 
Parameters for that trail or trail segment. For a Design Parameter 
expressed as a range of values (e.g., Design Tread Width, Design 
Clearing Width, and Design Turns), identify a specific value applicable 
to the trail or trail segment.

1.7--Establishment of Priorities and Management Requirements

    1. In addition to Trail Class, Managed Uses, Designed Use, and the 
Designed Parameters, consider the following when establishing 
priorities and management requirements for trail projects:
    a. Safety hazards to users.
    b. Potential for or occurrence of resource damage.
    c. Intensity of trail use.
    d. Whether the trail is located in such a way as to affect or 
benefit from other resource activities.
    e. Preliminary cost estimates for construction or reconstruction.
    f. Preliminary requirements for supplemental trailhead and other 
trail-related facilities needed to complement the trail system.
    g. Program funding, availability of volunteer support, and 
scheduling of work.
    h. Public desires.
    2. FSH 2309.18, section 1.6, exhibit 01, Trail Operation and 
Maintenance Considerations, offers general guidelines that assist in 
developing trail prescriptions and in subsequent program management, 
operation, and maintenance. The considerations are a general starting 
point and will likely be adapted to reflect local financial limitations 
and site-specific district, forest, or regional circumstances. 
Exceptions may occur at the trail-specific, district, forest, or 
regional level.

1.8--Considerations for Trail Planning

    1. The following section provides an example of a district trail 
plan resulting from the analysis process. Section 1.8, exhibit 01, 
illustrates the plotting of projects on a map; section 1.8, exhibit 02, 
shows the incorporation of a trail plan into the district trail 
inventory; section 1.8, exhibit 03, illustrates how a trail plan is 
addressed in the budget process.
    2. The following four trails in the trail plan illustrate how 
safety, protection of wilderness values, availability of resources, 
need for preconstruction, and availability to the user influence 
priority, scheduling, and management requirements.
    a. Big Rock Trail. This trail currently is managed for motorcycles, 
with a Designed Use of Motorcycle. Motorcycle use on the trail is high 
and increasing. The lower 5 miles meet the Motorcycle Design 
Parameters, except for brushing out. The upper 5 miles are less than 
standard and would require major reconstruction to meet the Motorcycle 
Design Parameters. The trail falls into Trail Class 3. The area is 
managed for a roaded natural experience. There are limited 
opportunities for motorcycle trails in the area.
    Analysis resulted in a decision to reconstruct the trail to meet 
the Motorcycle Design Parameters for Trail Class 3, so as to provide a 
high-volume, motorcycle trail consistent with the roaded natural 
character of the area. Preconstruction is necessary for the 
reconstruction.
    b. Kawishiwi Trail. This is an unauthorized, four-wheel drive road 
in a wilderness area. The trail use is low-volume, four-wheel driving 
and moderate-volume hiking. The management goal for the area is to 
eliminate illegal motorized use in this wilderness area and to 
naturalize sections of the four-wheel drive way. Inadequate parking at 
the trailhead is also a problem. If this trail were linked to the 
Moraine Trail, a single trailhead could serve both trails.
    Analysis resulted in a decision to close the route to vehicles and 
to allow it to revert to a moderate-volume, Trail Class 3 trail. 
Barriers to close the route are needed, and the parking facilities need 
to be decreased in order for the trail to qualify as Trail Class 3. 
Informational and regulatory signs are also needed. Actions are 
identified to hasten the return of this trail to a more primitive 
character. A short (1/3-mile) trail connecting the Kawishiwi Trail with 
the Moraine Trail will be constructed to allow use of a common 
trailhead. Planned use is consistent with the semiprimitive character 
and wilderness designation.
    c. Moraine Ski Trail. This trail currently is used for cross-
country skiing in the winter. Cross-country skiing on the trail is 
increasing rapidly, but users complain of a 3-mile segment that falls 
into Trail Class 2 on a long trail that generally falls into Trail 
Class 3. Preliminary reconnaissance indicates that minor clearing of 
brush and small trees has occurred and that marking of the trail is 
necessary. A local nordic club has volunteered to help on the project. 
This is one of few areas in this drainage where plowed roads provide 
winter access.
    Analysis resulted in a decision to change the Trail Class for the 
3-mile section from Trail Class 2 to Trail Class 3. Increased 
maintenance of those 3 miles will be required. Space is identified to 
expand the parking area and provide adequate parking to the shared 
trailhead with the Kawishiwi Trail. The desired recreation experience 
is consistent with the semiprimitive, non-motorized character of the 
area.
    d. Meadows Trail. The District identified a need and opportunity to 
construct a relatively short, interpretive hiking trail to provide day 
hiking near a major campground.
    Analysis based on estimated use resulted in a decision to construct 
a high-volume, Class 4 trail designed and managed for hiker/pedestrian 
use only. Other uses are prohibited. Planned use is consistent with the 
roaded natural character of the area.
