SCENIC VISTA MANAGEMENT ACTIONS IN THE 

MERCED RIVER CORRIDOR: SEGMENTS 2A, 2B & 3 

INTRODUCTION

The Scenic Vista Management Plan for Yosemite National Park Environmental Assessment (SVMP), 

completed in 2010, inventoried 181 potential vista points throughout the park, outside of wilderness and 

chiefly along the major roads. The plan outlined a programmatic framework for prioritizing and prescribing 

the work to be completed at each of the viewpoints necessary to obtain a desirable vista. The 2010 Finding of 

No Significant Impact (FONSI) stipulates that the final determination of vista points for the Merced Wild and 

Scenic River corridor would be deferred to the comprehensive river management plan completion. Once an 

alternative has been selected in a Record of Decision, the management actions included in that selected 

alternative will be incorporated into the Merced River Plan to guide the future management of scenic values 

in the Merced River corridor.

This approach captures the programmatic direction, methods outlined in the SVMP, and analyzes the 

viewpoints from the perspective of the Wild and Scenic Rivers Act mandate to protect and enhance the 

values of the Merced Wild and Scenic River. 

The scenery along the Merced River—considered an outstandingly remarkable value—offers outstanding 

views of the river valley, adjacent meadows, glaciated geology and hanging valleys. The locations where 

these tremendous views intersect with frequent visitation are often along roads and near historic buildings. 

As originally inventoried in the SVMP, eighty-three of these sites were located in, or adjacent to the Wild 

and Scenic River corridor of the Merced River. Upon analyzing these vista locations within the context of 

the Merced River Plan and considerations for river values (including free flow, water quality, and 

outstandingly remarkable values), thirty-two of these sites were removed from consideration. Reasons for 

removal range from sites encroaching on declared Wilderness areas, removal of the viewing area under 

proposed actions of the MRP, or sites being very similar to other nearby vistas. The inventory of sites 

includes analysis of each site with a Visual Resource Assessment (VRA) score that looks at a vista site with 

factors such as current infrastructure, numbers of scenic icons and quality of the view, and quantifies them 

for comparison. The sites are then prioritized by VRA score as high, medium or low based on their score up 

to eighteen. Low priority sites, scoring seven and below, are also be removed from consideration. The 

remaining sites are summarized and the proposed work actions analyzed regarding how the management of 

scenic vistas will take place as described under the Scenic Vista Management Plan, and comply with Merced 

River Plan to protect and enhance river values. As stated in the SVMP, the goal is not to remove all trees 

within a vista, but to remove a minimal number in order to allow a view, retain a natural appearance, and 

with the least invasive management practicable.

This appendix describes the impact over the projected life, typically twenty years for management plans, of 

the MRP. Some vistas are currently open, but will likely be encroached during this time frame, given past 

trends of conifer growth. The descriptions of estimated impact of trees removed during initial management 

for each vista point are by species and size as they are in 2012. Trees less than 6” diameter at breast height 

(dbh) can be removed in order to maintain a vista without additional compliance, and are not included in 

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS H-1 
APPENDIX H 

SCENIC VISTA MANAGEMENT ACTIONS IN THE MERCED RIVER CORRIDOR: SEGMENTS 2A, 2B & 3 

the estimates. If more trees than estimated over 6” dbh need to be removed, additional compliance will need 

to be completed. 

Following tree removal, the work area will be revegetated with native vegetation, if necessary, the soil will be 

decompacted, and the area recontoured. Stumps must remain in place to provide soil stability. In order to 

preserve the natural aesthetic, stumps will be flush cut and buried. Seed collection and plant salvage will 

occur as necessary for revegetation after site work and tree removal are complete. An annual work plan will 

continue to be done that will describe the specific actions involved in initial management of removing larger 

trees, and maintenance involving revegetation or removing trees under 6” dbh. Approximately ten to twenty 

vista points will be done each year. This work plan will be posted on-line as described in the SVMP. 

In the initial management of a vista, some downed trees may be left, but this will generally be no more than 

one tree in twenty. Trees which are removed will be used for traditional cultural purposes, chipped, left as 

woody debris in the river, or hauled away. If chipped, wood chips would remain on site (outside of 

meadows) as mulch (no more than 1 inch deep). The small diameter vegetation is to be lopped and scattered 

such that any saw marks are not visible from the vista point. Remaining woody debris which maybe left will 

depend on the conditions at the time. Woody debris left on site must adhere to the Fire Management Plan

guidelines of tons per acre of downed fuel levels. 

Maintaining these viewpoints will further enhance the visitor’s recreation enjoyment and enhance their 

connection to the natural world along the Merced River. At the same time, management of scenic vistas at 

these select locations must protect biological, cultural values (archeological sites and places of significance 

to American Indian tribes and groups), water quality, and the free-flowing condition of the river. 

Management will involve removal of trees, and when completed following careful review and attention to 

ORV protection will ensure that all other biological and cultural values are minimally affected. The 

outstandingly scenery will continue to evolve in response to natural ecological processes.

Providing and maintaining viewing areas at existing infrastructure (such as roadside turnouts) lessens the 

frequency of visitors creating or using social trails in order to see a view that is referred to in existing signs 

and publications. Many park visitors’ (87%) primary purpose when visiting the park is to take a scenic drive 

(Littlejohn et al 2006). Removing a limited number of trees in locations which support visitor use will give 

visitors an incentive to remain on durable surfaces and therefore not tread in more sensitive areas. Through 

visitors remaining on durable surfaces, the environment will be better protected and biological resources 

will be enhanced. Vista management in the Merced WSR corridor should reestablish vistas that once 

existed, without degrading other outstandingly remarkable values. What follows is a description of the work 

plan for each of the viewpoints established for the Merced River corridor. Each work plan provides

• A description of the viewpoint and its specific location

• Ecological considerations, particularly as they pertain to vegetation 

• A summary of the trees greater than 6” dbh that currently are, or potentially could, obscure the vista 

over the next twenty years. Trees are described by species and size dbh as of 2012.

# 152: Bridalveil Fall Approach (10.25-High)

Location: Southside Drive

View: Bridalveil Falls

The Bridalveil Fall Approach is located on 

Southside Drive, 0.30 miles east of Pohono 

Bridge. Southside Drive heads directly to the 

falls before turning to the east at Bridalveil 

Meadow. This is one of the first waterfalls 

visitors see when entering the Yosemite 

Valley. The current view of the fall is very 

narrow and can only be seen along a brief 

segment of road. Further encroachment of 

mature trees from the sides of the road could 

block the view completely. This site contains 

a large number of cedar, fir and ponderosa 

saplings/seedlings that would need to be 

removed in the initial management of the site. 

The road in its current configuration was 

completed in 1928. Trees established before 1928 should not be removed.

The site was inventoried as part of the Scenic Vista Management Plan as site number 152. This site rated a 

high priority with an average VRA score of 10.25 out of 18.

The Roosevelt Turnout is located 0.45 miles 

east Pohono Bridge. The focal point of the 

Roosevelt Turnout is Bridalveil Falls with a 

portion of Bridalveil meadow in the 

foreground. This sign commemorates the 

general location of where John Muir and 

Theodore Roosevelt camped in 1903. The 

current view is completely obscured by many 

conifers going back to the Wawona Road. A 

number of trees less than 6” dbh would also be 

removed during initial management of the site.

The road in its current configuration was 

completed in 1928. Trees established before 

1928 should not be removed.

The site was inventoried as part of the Scenic Vista Management Plan as site number 156. This site rated a

Location: Southside Drive

View: Bridalveil Falls

The Bridalveil Straight interpretive sign is 

located 0.25 miles east of the intersection of 

Southside Drive and Wawona Road. This 

vista is listed as a contributing feature to the 

Yosemite Valley Historic District. The focal 

point of the vista to be managed is Bridalveil 

Fall to the south. This location also has 

spectacular view of El Capitan to the east, 

over California Black Oaks. It is unlikely the 

oak trees will grow tall enough to obscure the 

view to El Capitan, but this area should also 

be monitored in the future for conifer 

encroachment.

The road in its current configuration was 

constructed in 1928. Trees established before 

1928 should not be removed.

The site was inventoried as part of the Scenic Vista Management Plan as site number 38. This site rated a 

high priority with an average VRA score of 13 out of 18.

The Bridalveil Fall Foot Bridge is located on 

the Bridalveil Fall trail at the base of the fall. 

This vista is from one of three bridges built in 

1913 at the waterfall. These are the oldest 

remaining bridges in the valley. The intention 

in managing this vista is not to create a broad 

view, but a focused and intimate view of the 

fall.

Trees established before 1913 should not be 

removed.

The site was inventoried as part of the Scenic 

Vista Management Plan as site number 37.

This site rated a medium priority with an

# 226: Cathedral Beach Parking (9.75-Medium)

Location: Southside Drive

View: Three Brothers

The Cathedral Beach Parking area is located on 

Southside Drive 0.25 miles east of the 

El Capitan Crossover. 

This vista is located on the terrace above the 

restroom. There were two vistas inventoried 

from this area, this one, and another from the 

beach. The recommendation is to manage the 

vista from this location and not the vista from 

the beach. The view to Three Brothers is 

similar, and new parking could be built in this 

location to better accommodate visitors. Trees 

established before 1928 should not be removed 

when managing this vista.

The site was inventoried as part of the Scenic Vista Management Plan as site number 226. This site rated a

# 3: El Capitan Postage Stamp Turnout (9.5-Medium)

Location: Northside Drive

View: El Capitan, Merced River

The El Capitan Postage Stamp Turnout is 

located on Southside Drive 0.45 miles east of 

the El Capitan Drive intersection. The history 

of this vista began in 1868 when Carlton 

Watkins captured a photograph of El Capitan a 

few feet from the current turnout in 1868. This 

photograph was used in a postage stamp in 

1934. It was a popular vista at one time, but is 

now almost completely obscured with conifers. 

There are a large number of dead trees in the 

area and the intention is to remove the smaller 

trees that have less habitat value and also 

reduce the fuel load. Several large deciduous 

riparian trees partially obscure the view, but 

will not be removed for vista management 

because of their high habitat potential.

The road was completed in 1928, so trees established before then should not be removed.

The site was inventoried as part of the Scenic Vista Management Plan as site number 3. This site rated a 

medium priority with an average VRA score of 9.5 out of 18.

Ferry Bend Turnout is located on Southside 

Drive 1.17 miles east of the El Capitan Road 

intersection. The turnout is near where Ira 

Folsom began a ferry in 1871 to cross the 

Merced. The vista of the river and El Capitan 

is a contributing feature to the Yosemite 

Valley Historic District. The vista should be 

managed from the turnout to allow people to 

enjoy the view with minimal damage to the 

vegetation. Trees established before 1928 

should not be removed from this location for 

vista management.

This site has a considerable number of snags 

from a managed burn in 2004. The area surveyed is approximately 4 acres. The intention is to remove snags 

less than 12” dbh, and retain any larger snags. This would retain 23 snags between 20” and 40” dbh, and 

remove 53 snags less than 12” dbh. There would also be a considerable number of cedar saplings and trees 

less than 6” dbh removed.

Sentinel Beach is adjacent to the Sentinel 

Beach picnic area located off of Southside 

Drive 1.7 miles east of the intersection of 

El Capitan Road. This is a popular destination 

for picnicking, and is also the pullout and 

shuttle stop for raft rentals. Trees established 

before 1928 should not be removed from this 

location.

An alternative picnic and parking area is 

considered under the MRP at the location 

initially surveyed. It is recommended that this 

site is managed within the new developed area 

because it would create a better, more durable 

platform for visitors’ to enjoy the vista. 

The site was inventoried as part of the Scenic Vista Management Plan as site number 22. This site rated a

although some alteration in the trail took place in 

the 1920s, and the trailhead was likely rerouted at 

that time. 

The road in its current configuration was completed 

in 1928. Therefore trees established before 1928 

should not be removed.

There has been a footbridge in this location since 

1938. An older bridge 200 feet downstream was 

destroyed in a flood which resulted in the 

construction of the 1938 bridge. The current

structure was built in 1966. 

Vista should be monitored and maintained, but no 

removal of trees larger than 6” dbh is 

recommended. Trees that are partially obscuring 

the lower falls are riparian deciduous trees that 

shade the river and have high habitat potential.

south bank of the Merced River, looking to 

Yosemite Falls. Trees to be removed are north 

of the river. No riparian species are to be 

removed. Although this meadow has 

numerous examples of historic photographs 

from the 19th century, the year of 1928 is a 

conservative date that can establish the 

Southside Drive and turnouts in its present 

location as an intended vista point. Trees 

established before 1928 should not be removed.

Location: Southside Drive

View: Yosemite Falls, Merced River

Old Hutchings View is located adjacent to the 

southwest corner of Sentinel Bridge. This vista 

looks across the Merced River to Yosemite 

Falls. This is the view that originated from the 

Hutchings House (also called the Upper Hotel) 

that was across Southside Drive. The original 

hotel began in 1859, and was added onto 

during the tenure of James Hutchings. The 

current Sentinel Bridge was built in 1994, a 

replacement to a series of bridges that have 

been in this general location. A conservative 

date for the current location of the vista is 1928 

with the layout of Southside Drive. Trees 

established before this time should not be 

removed. There are numerous conifer saplings 

that will also be removed during initial management of the site.

# 28: Sentinel Bridge (13.5-High)

Location: Sentinel Drive

View: Half Dome, Merced River

The Sentinel Bridge is located at the 

intersection of Southside drive and Sentinel 

Drive. The bridge gives visitors views of Half 

Dome over the Merced River, and filtered 

views of the Upper Yosemite Falls to the west. 

The view of Half Dome in the reflected light 

of sunset over the river has been noted as 

being particularly dramatic. The current 

bridge was constructed in 1994, although this 

is likely the area of the first bridge over the 

Merced River in the Valley beginning in the 

1860s. The state of California replaced James 

Hutching’s timber bridge (that had replaced a 

previous bridge) with a steel bridge in 1878. 

This bridge was then replaced with a concrete span in 1919, and expanded in 1960. A conservative, 

definitive year to reference in the management of the vista is 1878, with the first steel bridge. Therefore any 

tree established before 1878 should not be removed.

Because of the vista’s close ties to the river, it should be noted that no deciduous riparian species, or trees 

overhanging the river will be removed. There are numerous conifer saplings that should also be removed 

during the initial management of the vista.

The site was inventoried as part of the Scenic Vista Management Plan as site number 28. This site rated a 

high priority with an average VRA score of 13.5 out of 18.

# 12: Sentinel Bridge Parking (11.5-High)

Location: Sentinel Drive

View: Yosemite Falls

The Sentinel Bridge Parking area is located on 

the northern side of the Merced River 

adjacent to Sentinel Bridge on Sentinel Drive.

The current Sentinel Bridge Drive was 

constructed in 1956, bypassing the previous 

road from the previous bridge, across Cook’s 

Meadow, to the falls. The vista dates to the 

time of the construction of the bridges in this 

location, and should be considered from the 

period of 1878. The current parking area, bus 

stop and walkways provide excellent 

opportunity to view Cook’s Meadow and 

Yosemite Falls. The main vista from this 

location is yosemite falls across Cook’s meadow. The view of the meadow is as important as the view of the 

waterfall, and as a result the trees recommended for removal are conifers encroaching on the meadow. 

The site was inventoried as part of the Scenic Vista Management Plan as site number 12. This site rated a 

high priority with an average VRA score of 11.5 out of 18.

The Housekeeping Camp Bridge over the

Camp, located a half mile east of Sentinel 

Bridge. This bridge was constructed in 1929 

and is a contributing structure to the 

Yosemite Valley Historic District. The 

primary vista is of Yosemite Falls, over the 

Merced River, There are a limited number of 

ponderosa pines in the middle ground, 

approximately 500 meters downstream that 

could grow taller and block the view in the 

future. It is recommended to monitor and 

manage this vista and remove the trees if 

necessary in the future. No trees established 

before 1929 should be removed.

This vista is similar to the nearby vista inventoried at Housekeeping Beach. It is recommended to manage 

the bridge vista, and not the beach vista, because management actions would be identical.

The rockfall hazard zone has recently been

buffer the impact, and potential damage, of 

rockfall by absorbing some of the force and rock 

debris. Most of the trees currently obscuring the

which are encroaching on the meadow. There 

are trees to the south of the Meadow could 

obscure the Spires in the future. The circulation 

in the Valley was generally set in 1928 and 

therefore no trees established before this time 

should be removed.

The site was inventoried as part of the Scenic Vista Management Plan as site number 42. This site rated a 

high priority with an average VRA score of 12.25 out of 18.

The El Capitan Meadow vista is in the northeastern 

portion of El Capitan Meadow. The vista includes a 

large portion of the Yosemite Valley with iconic 

natural landmarks such as El Capitan, The Three 

Brothers, Cathedral Rocks, and the Cathedral 

Spires. The viewpoint is part of the Yosemite Road 

Guide (marker V8). Views from Northside Drive to 

El Capitan are also listed as a contributing vista to 

the Yosemite Valley Historical District. The 

Meadow is a popular location for visitors to watch 

climbers ascending the Yosemite Valley walls. The 

Merced River Plan proposes constructing a 

boardwalk into the meadow. If a boardwalk is built, 

the vista should be managed from that location. No 

trees should be removed from within the rockfall hazard zone. 

Northside Drive in its current configuration was established by 1928; therefore trees established prior to 

this date should not be removed.

The site was inventoried as part of the Scenic Vista Management Plan as site number 33. This site rated a

The Hanging Valley Viewpoint is on Northside 

Drive, approximately one mile west of El Capitan 

Crossover. The viewpoint gives visitors views across 

the Merced River to well-known Yosemite 

landmarks including Bridalveil Falls and the Leaning 

Tower. The viewpoint is part of the Yosemite Road 

Guide (marker V10) and is a contributing vista to the 

Yosemite Valley Historic District. The vista looks 

over a stand of California Black Oaks. The intention 

of managing this vista is to remove conifers 

encroaching into the oaks. Several trees will also be 

removed from the upper bank on the north side of 

the Merced River.

The current configuration of Northside Drive is in place by 1928, therefore trees established before this time 

should not be removed.

Valley View is at the west end of Northside Drive. 

This is the vista on the 2010 quarter from the US 

Mint’s “America the Beautiful” series. The 

viewpoint is part of the Yosemite Road Guide 

(marker V11) which describes it as being a view of 

the “gates” of Yosemite with El Capitan on the left 

and Cathedral Rocks on the right. The landscape of 

the surrounding Yosemite Valley is reflected in the 

calm water of the Merced River. The primary 

objective in managing the vista is to open the mostly 

obscured view of Bridalveil Fall, and to reduce the 

number of conifers encroaching on the meadow.

There are a large number of dead trees from a 

controlled burn in 2007. The area from which trees 

will be removed is approximately 4 acres. There are 117 snags within this area, and of these, those less than 

12” dbh will be removed and larger snags of greater habitat value will remain.

Northside Drive in its current configuration was in place by 1928. Therefore trees established before this 

time should not be removed.

View: Cascade Falls

Cascade Falls is located three miles east of the 

Arch Rock entrance station. The falls can be 

viewed from a formal viewing point located 

adjacent to the Cascade Falls parking area. 

The current view of the falls is narrow and 

should be opened to allow better visibility. 

Mature trees and shrubs in front of the 

viewing area and falls could obscure the view 

in the near future. This site contains mature 

California Black Oak, which is a species that 

will not be removed in a medium value vista. 

The oaks are growing between the viewing 

area and the waterfall, but they are unlikely to 

become much taller, and as a result will likely 

obscure only the bottom of the falls.

The El Portal Road was constructed in 1908, but turnouts were not added until 1932. Trees established 

before 1932 should not be removed.

The site was inventoried as part of the Scenic Vista Management Plan as site number 35. This site rated a

PURPOSE OF THIS AGREEMENT

This programmatic agreement (PA) supplements 36 CFR Part 800 and the 2008 Programmatic Agreement 

Among the National Park Service (U.S. Department of the Interior), the Advisory Council on Historic 

Preservation, and the National Conference of State Historic Preservation Officers for Compliance with Section 

106 of the National Historic Preservation Act herein referred to as 2008 Nationwide PA and attached as 

(Exhibit 2). This PA recognizes the extensive consultation to date among the NPS, SHPO, ACHP, 

traditionally-associated American Indian tribes and groups, and other consulting parties in accordance with 

36 CFR, Part 800.1 – 5. The extent of adverse effects will require future identification, evaluation and 

assessment of effects to be determined for numerous actions of the Final Merced River Plan /EIS and 

consultation will continue prior to implementation of those actions. However, there are numerous actions 

that the consulting parties have reached agreement that result in No Historic Properties Affected, No 

Adverse Effect, or Adverse Effect. 

APPLICABILITY

This PA only applies to actions proposed in the Final Merced River Plan /EIS and is not intended to 

establish a process for all consultation, review, and compliance activities within the Merced River corridor.

The terms in 36 CFR § 800.16 “Definitions” are applicable throughout this PA; and 

I. Responsibilities, Qualifications, and Training

In addition to 36 CFR Part 800.2 and Stipulation I.A of the 2008 Nationwide PA (Exhibit 2), the following 

responsibilities of the National Park Service apply to this programmatic agreement:

A. Park American Indian Liaison

The Yosemite National Park (YOSE) American Indian Liaison will serve as the Superintendent’s designated 

representative in government-to-government consultations with tribal groups. The YOSE American Indian 

I-2 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS
Applicability

Liaison will provide day-to-day staff support for Section 106 consultation with traditionally-associated 

American Indian tribes and groups and serve as a liaison communicating tribal concerns, suggestions, and 

recommendations to park subject matter specialists, other NPS offices, and others involved in the 

implementation of the undertaking. 

II. Consultation

In addition to 36 CFR Part 800.1 – 6 and Stipulation II.A of the 2008 Nationwide PA (Exhibit 2), the 

following consultation provisions apply to this programmatic agreement:

A. Participation of traditionally-associated American Indian tribes and groups

The federal government has a unique legal relationship with American Indian tribes set forth in the 

Constitution of the United States, treaties, statutes, and court decisions. This relationship is further 

informed and guided by Executive Orders and NPS agency management policies, which underscore the 

important relationship that traditionally-associated American Indians have with park lands and resources. 

The NPS is aware that historic properties of religious and cultural significance to American Indian tribes 

and groups are located on ancestral lands now encompassed by Yosemite National Park. Consultations with 

Indian tribes will be conducted in a sensitive manner, respectful of tribal sovereignty, and recognizing the 

Government-to-Government relationship between the NPS and tribes. The NPS and American Indian 

tribes and groups will continue to collaborate on resources management and historic preservation activities 

guided by existing cooperative agreements to ensure that adverse effects to historic properties with 

traditional religious and cultural significance can be avoided.

Exhibit 1 presents a list of existing agreements Yosemite National Park has with traditionally-associated 

American Indian tribes and groups.

III. Streamlined Review Process

There are no additional provisions proposed beyond the Streamlined Review process set forth in the 2008 

Nationwide PA (Exhibit 2).

IV. Standard Review Process

In addition to 36 CFR Part 800.3 – 6 and Stipulation IV of the 2008 Nationwide PA (Exhibit 2), the 

following criteria provisions apply to this programmatic agreement regarding the use of the standard review 

process:

A. Defining the Merced River Plan undertaking and Identifying Consulting Parties

The Merced River Plan undertaking is presented as Alternative 5: Enhanced Visitor Experience and 

Essential River Bank Restoration (agency-preferred) in the Final Merced River Plan /EIS which addresses 

protection and enhancement of river values, visitor use and user capacity management, and land use and 

development within the river corridor. A substantial portion of these actions are directly related to river 

value protection and enhancement. Many actions in Merced River Plan undertaking affirm the retention of 

existing infrastructure (buildings, structures, and sites), visitor and commercial services, and administrative 

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS I-3
PROGRAMMATIC AGREEMENT REGARDING COMPLIANCE WITH SECTION 106 OF THE NATIONAL HISTORIC PRESERVATION ACT

functions that were not evaluated in the Section 106 Report. However, a complete list of actions for 

Alternative 5 can be found in Appendix K of the Final Merced River Plan/EIS. 

Planning for the Merced River Plan undertaking has been carried out in consultation with state, federal, and 

local agencies; and traditionally-associated American Indian tribes and groups. Consistent with 36 CFR Part 

800.3(b) and 36 CFR Part 800.8, the review process for Section 106 of the National Historic Preservation Act

was initially coordination with the National Environmental Policy Act (NEPA) public participation process 

on the Draft Merced River Plan/EIS. However, the consulting parties have continued to engage in rigorous 

Section 106 compliance efforts independent of the NEPA process as described in Appendix J: National 

Historic Preservation Act Assessment of Effects for the Final Merced River Plan /EIS.

B. The Area of Potential Effect (APE)

The NPS has determined that the Area of Potential Effect (APE) for the undertaking, in consultation with 

the consulting parties, as defined in 36 CFR § 800.16(d), as 1.5 miles on each side of the Merced River’s 

ordinary high water mark and includes the entirety of the known archeological and historic districts 

(Exhibit 3).

Should revision of the APE become necessary to address actions in the Merced River Plan undertaking, NPS 

shall notify the consulting parties and seek comments on proposed revision(s). 

C. Assessment of Effects on Historic Properties

The NPS has determined in consultation with SHPO, ACHP, traditionally-associated American Indian 

tribes and groups, and other consulting parties that two categories of actions regarding assessment of effects 

will be guided by this PA for Section 106 compliance during implementation of the Merced River Plan

undertaking:

• Category 1 actions represent “No Historic Properties Affected” or “No Adverse Effects” and no 

further consultation is required; and

• Category 2 actions represent “Adverse Effects” to known historic properties, which the NPS, in 

consultation with the SHPO, ACHP, traditionally-associated American Indian tribes and groups, 

and other consulting parties as appropriate, shall work to minimize and/or mitigate adverse effects 

in project-specific agreements as necessary. 

For Category 3 Actions in the Final Section 106 Report, future identification, evaluation and or assessment 

of effects determinations will be guided by 36 CFR Part 800 and the 2008 Nationwide PA.

D. Category 1 – No Historic Properties Affected or No Adverse Effect

To evaluate the Merced River Plan undertaking, the NPS used the information on known historic 

properties to make determinations of effect where possible. As such, numerous actions have adequate 

information so that the extent of effects is clear and the historic properties affected are known. 

Exhibit 4 presents a table of actions in the Merced River Plan undertaking that have been determined, based 

on known historic properties and clear action descriptions – in consultation with SHPO, ACHP, 

traditionally-associated American Indian tribes and groups, and other consulting parties – to result in either 

“No Historic Properties Affected” or “No Adverse Effect” and shall be implemented without further review 

or consultation with SHPO and ACHP. The NPS and American Indian tribes and groups will continue to 

I-4 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS
Applicability

collaborate on resources management and historic preservation activities guided by existing cooperative 

agreements to ensure that adverse effects to historic properties with traditional religious and cultural 

significance can be avoided.

E. Category 2 – Adverse Effect

Exhibit 5 presents a table of actions within the program of the Merced River Plan undertaking that have 

been determined, based on known historic properties and clear action descriptions – in consultation with 

SHPO, ACHP, traditionally-associated American Indian tribes and groups, and other consulting parties – to 

result in an adverse effect that cannot be avoided. 

Therefore, the NPS, in consultation with the SHPO, ACHP, traditionally-associated American Indian tribes 

and groups, and other consulting parties (including the public) as appropriate shall seek ways to resolve 

adverse effects through project specific agreements such as a Memorandum of Agreement or Programmatic 

Agreement which will specify all measures taken to avoid, minimize, or mitigate the adverse effects for the 

action. 

F. Annual Report and Meeting

The NPS will include information regarding the Merced River Plan undertaking to the SHPO, ACHP, and 

traditionally-associated American Indian tribes and groups annually in the form of a hard-copy and 

electronic report. The annual report will provide an update on identification, evaluation, assessment of 

effects determinations, and implementation actions as required by the specific actions outlined in Exhibits 4 

and 5. As necessary, an annual meeting will be scheduled with the consulting parties to discuss this 

information and other issues of interest.

V. National Historic Landmarks

There are no additional provisions proposed for National Historic Landmarks set forth in 36 CFR Part 

800.10 and the 2008 Nationwide PA (Exhibit 2).

VI. Inadvertent Discoveries

The provisions set forth in 36 CFR Part 800.13 and 36 CFR 10 (Native American Graves and Repatriation 

Act) shall be followed, and those stipulated in the 2008 Nationwide PA (Exhibit 2) would be replaced for 

this programmatic agreement with the following:

A. Inadvertent Discoveries

If it appears that an action of the undertaking will affect a previously unidentified property that may be 

eligible for inclusion in the National Register or affect a known historic property in an unanticipated 

manner, NPS will halt project activities in the vicinity of the discovery, and take all reasonable measures to 

avoid or minimize harm to the property. Within two (2) working days of the discovery, NPS shall notify 

SHPO via telephone and electronic mail of the discovery, and shall provide SHPO with a proposed schedule 

for assessing eligibility and development of treatment recommendations via electronic mail. 

SHPO shall respond to NPS within two (2) working days of the notification via electronic mail. NPS shall 

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS I-5
PROGRAMMATIC AGREEMENT REGARDING COMPLIANCE WITH SECTION 106 OF THE NATIONAL HISTORIC PRESERVATION ACT

take into account SHPO’s recommendations regarding National Register eligibility and proposed actions, 

and then shall carry out appropriate actions. NPS shall provide SHPO a report of the actions when they are 

completed. If SHPO fails to respond within this time, NPS shall proceed to the next step in the design 

process.

If an action of the undertaking could affect a previously unidentified property that may be of cultural or 

religious significance to traditionally-associated American Indian Tribes and Groups, or a known property 

in an unanticipated manner, NPS will halt project activities in the vicinity of the discovery, and take all 

reasonable measures to avoid or minimize harm to the property. Within two (2) working days of the 

discovery, NPS shall notify traditionally-associated American Indian tribes and groups via electronic mail 

with a proposed schedule for assessing eligibility and development of treatment recommendations.

B. American Indian Human Remains

NPS shall ensure that any American Indian burials or American Indian human remains, funerary objects, 

sacred objects and objects of cultural patrimony discovered during implementation of an undertaking, 

archeological fieldwork, or other actions, are treated with appropriate respect and according to federal law, 

including, but not limited to, the Native American Graves Protection and Repatriation Act, Public Law 101-

601 (NAGPRA) and its implementing regulations (36 CFR § 10, Native American Graves and Repatriation 

Act Regulations). Actions described herein do not constitute compliance with provisions of NAGPRA.

If objections are raised by any Indian Tribe regarding treatment of human remains or cultural items as 

defined under NAGPRA, the objection shall be resolved in accordance with NAGPRA. NPS shall notify the 

SHPO and the ACHP of any such dispute if so requested by involved tribes.

VII. Emergency Actions

There are no additional provisions proposed for Emergency Actions as set forth 36 CFR Part 800.12 or the 

2008 Nationwide PA (Exhibit 2).

VIII. Review and Monitoring of PA Implementation

There are no additional provisions proposed for Review and Monitoring of PA Implementation as set forth 

in the 2008 Nationwide PA (Exhibit 2).

IX. Subsequent Agreements

There are no additional provisions proposed for Subsequent Agreements as set forth in the 2008 

Nationwide PA (Exhibit 2).

X. Dispute Resolution

There are no additional provisions proposed for Dispute Resolution as set forth in the 2008 Nationwide PA 

(Exhibit 2) or 36 CFR 800.6.

I-6 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS
Applicability

XI. Termination

NATIONAL HISTORIC PRESERVATION ACT 

ASSESSMENT OF EFFECT FOR SITE-SPECIFIC ACTIONS

EXECUTIVE SUMMARY

The National Park Service has developed the Merced Wild and Scenic River Final Comprehensive Management 

Plan and Environmental Impact Statement, which is intended to guide the management of the Merced Wild and 

Scenic River corridor within the boundaries of Yosemite National Park and the El Portal Administrative Site. 

The plan and its environmental impact statement, which evaluates potential impacts of a range of alternatives, 

are referred to collectively as the Merced River Plan undertaking. The Merced River Plan undertaking directs 

the protection of the river’s free-flowing condition and the values that make it worthy of designation and will:

• Establish the boundaries, segment classifications (as wild, scenic, or recreational) of the Merced Wild 

and Scenic River, and provide a clear process for protection of the river’s free-flowing condition in 

keeping with the Wild and Scenic Rivers Act (WSRA) Section 7.

• Refine descriptions of the river’s outstandingly remarkable values (ORVs), which are the unique, rare, 

or exemplary river-related characteristics that make the river eligible for inclusion in the National Wild 

and Scenic Rivers System and document the conditions of these ORVs, water quality, and free-flowing 

condition of the river.

• Identify management objectives for the river, and specific actions and/or programs that will be 

implemented to achieve the objectives and commit to a program of ongoing studies and monitoring to 

ensure that river values are protected and enhanced over the life of the plan.

• Establish a user-capacity program that addresses the kinds and amounts of public use that the river 

corridor can sustain while protecting and enhancing the river’s outstandingly remarkable values.

• Fulfill the specific direction of the 1987 legislation designating the Merced River as a component of the 

National Wild and Scenic River System (16 U.S.C. Section 1274 (a)(62)(A)) and make appropriate 

revisions to the park’s 1980 General Management Plan. 

The Merced Wild and Scenic River Draft Comprehensive Management Plan/Environmental Impact Statement 

(Draft Merced River Plan/EIS) was published and distributed for a 112-day public review beginning January 8, 

2013 and ending April 30, 2013. This document analyzed six alternatives. Alternative 1 (No Action) would 

continue current management and trends in the condition of river values. Alternatives 2-6 would protect and 

enhance river values, implement a visitor use and user capacity management program, and call for a suit of 

actions related to land use and development. The action alternatives vary primarily in the degree of restoration 

and the amount of visitor use that could be accommodated by the commensurate level of facilities and services 

necessary to protect river values. 

The guiding principles of Alternative 5 (preferred) as proposed in the Final Merced River Plan/EIS would 

include essential ecological restoration within 100 feet of the river and in meadow and riparian areas, necessary

cultural resource protection and enhancement, accommodation of a daily visitation level in Yosemite Valley 

that would be similar to those observed in recent years, and relocates a select number of facilities and services

outside the river corridor.

Specific actions called for in Alternative 5 would:

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS J-1
NATIONAL HISTORIC PRESERVATION ACT ASSESSMENT OF EFFECT FOR SITE-SPECIFIC ACTIONS

• Restore 189 acres of meadow and riparian habitat. 

• Significantly increase the campsite inventory in all river segments (+36%) and in Yosemite Valley 

(+37%).

• Minimally increase available lodging in all river segments (3%) and in Yosemite Valley (+5%). 

• Increase day-use parking spaces in Yosemite Valley (+8). 

• Reduce some commercial services and relocate others outside the river corridor. 

• Make significant changes to the traffic circulation pattern in Yosemite Valley to accommodate 

ecological restoration goals and reduce traffic congestion. 

• Accommodate approximately 20,100 visitors per day in East Yosemite Valley.

• Continue to manage overnight-use capacity through Wilderness permits and reservation systems for 

lodging and camping.

• Manage day-use capacity for East Yosemite Valley through intentional traffic diversions and 

monitoring. 

There are many actions proposed in the plan that would improve conditions for historic properties associated 

with river-related/river-dependent, rare, unique and exemplary outstandingly remarkable values (see 

Chapter 5). However, some actions proposed in the Merced River Plan undertaking would result in 

unavoidable adverse effects that would need to be minimized or mitigated. The final preferred alternative 

would result in adverse effects due to the following types of actions: 

• Physical destruction of or damage to all or part of the property 

• Alteration of a property, including restoration, rehabilitation, repair, maintenance, stabilization, 

hazardous material remediation and provision of handicapped access, that is not consistent with the 

Secretary of the Interior’s Standards for the Treatment of Historic Properties (36 CFR part 68) and 

applicable guidelines

• Demolition or relocation of a property from its historic location

• Change of the character of the property’s use or of physical features within the property's setting that 

contribute to its historic significance

• Introduction of visual, atmospheric or audible elements that diminish the integrity of a property's 

historic features; [36 CFR Part 800.5(a)(2)]

36 CFR PART 800.3 INITIATION OF THE SECTION 106 PROCESS (STEP 1 OF 4) 

Project Purpose and Need

The purpose of the Merced River Plan undertaking is to preserve the river in free-flowing condition, and to 

protect the water quality and outstandingly remarkable values (ORVs) that make the river worthy of 

designation, for the benefit and enjoyment of present and future generations. In accordance with WSRA, “the 

plan shall address resource protection, development of lands and facilities, user capacities, and other 

management practices necessary or desirable to achieve the purposes of this Act” (WSRA Section 3(d)). The 

Final Merced River Plan/EIS will fulfill the specific direction of the 1987 legislation designating the river as a 

component of the National Wild and Scenic River System (16 U.S.C. Section 1274 (a)(62)(A)) and will make 

appropriate revisions to the 1980 Yosemite General Management Plan. 

Definition of the Undertaking

The Merced River Plan undertaking is presented as Alternative 5: Enhanced Visitor Experience and Essential 

River Bank Restoration (agency-preferred) in the Final Merced River Plan /EIS. The undertaking addresses

protection and enhancement of river values, visitor use and user capacity management, and land use and 

development within the river corridor. A substantial portion of these actions are common to all action 

alternatives and are directly related to river values. Many actions in Merced River Plan undertaking affirm the 

retention of existing infrastructure (buildings, structures, and sites), visitor and commercial services, and 

administrative functions that are not evaluated in the Section 106 Report. However, a complete list of actions 

for Alternative 5 can be found in Appendix K of the Final Merced River Plan/EIS. 

Relevant actions of the Merced River Plan undertaking that have the potential to affect historic properties 

(individual and districts) are presented in three categories for the assessment of effects. Category 1 actions are 

those that will either result in “No Adverse Effects” or “No Historic Properties Affected;” Category 2 actions 

are those that will likely result in “Adverse Effects;” and Category 3 actions require “Identification, Evaluation, 

and/or Assessment of Effect to be Determined.”

The National Park Service in consultation with the SHPO, ACHP, traditionally-associated American Indian 

tribes and groups, the NTHP, and the HBF are in the process of developing a programmatic agreement that will 

outline the process for consultation for each category of actions as they are implemented over the coming 

decades. 

Public and Consulting Party Participation

The NPS has taken advantage of various opportunities for public participation in the Section 106 process, all of 

which have corresponded with general public outreach for the plan. Public comment regarding historic 

properties has ranged from management of specific contributing resources such as the historic bridges in 

Yosemite Valley, to general cultural resource management approaches regarding identification, protection, and 

consultation with stakeholders. 

The public also commented on identification and management of the wild and scenic river’s cultural 

outstandingly remarkable values (ORVs). Management of these values is required under the Wild and Scenic 

Rivers Act and does not necessarily parallel the identification and management of historic properties under the 

NHPA. These public involvement steps are highlighted below in chronological order.

NATIONAL HISTORIC PRESERVATION ACT ASSESSMENT OF EFFECT FOR SITE-SPECIFIC ACTIONS

2009 Summer/Fall/Winter: Initiation of the Section 106 Process

Initiation of the Section 106 process occurred concurrently with the workshops held during the public scoping 

period. A series of 18 public workshops were held, each of which included presentations on the scope, history, 

and purpose of the plan. Participants were asked questions about what they valued and what they wanted to see 

protected in the river corridor, and what, if anything, should be changed. The NPS received the following input 

regarding cultural resources:

• The Merced Wild and Scenic River Comprehensive Management Plan should identify goals, 

measurable objectives, and management prescriptions that explain specifically how the agency will 

define, protect, and enhance the Cultural ORV. 

• The Merced Wild and Scenic River Comprehensive Management Plan should provide for the 

protection of all historic structures and buildings, including the Yosemite Valley bridges. 

• The NPS should promote the diverse heritage of Yosemite National Park by providing interpretive 

experiences, and access to historic resources and facilities. 

• The Merced Wild and Scenic River Comprehensive Management Plan should call for the removal and 

ecological restoration of the area known as Superintendent's Residence (Residence 1). 

• The NPS should protect and enhance the historic orchards of Yosemite Valley.

• The Merced Wild and Scenic River Comprehensive Management Plan should protect and enhance the 

cultural connections reflected by the continuum of use by American Indian peoples, especially the 

tangible resources that reflect ancestral heritage (e.g., archeological sites).

• The NPS should not remove the abandoned sewage treatment plant at El Portal to protect the 

prehistoric burials in the area. 

• The NPS should conduct consultation with traditionally-associated American Indian peoples who are 

lineal descendants. Furthermore, the NPS should analyze and resolve the Paiute and Miwok lineal 

descendent concerns before defining the Cultural ORV. 

• The Merced Wild and Scenic River Comprehensive Management Plan should protect and enhance 

traditional cultural resources including archeological sites, scenic resources, and natural resources 

with traditional cultural uses.

2011 Fall: Alternatives Development Workshops

This series of five workshops provided an opportunity to solicit early public input on the options the NPS 

considered to protect river values, or to address user capacity or land-use management for the Merced River 

Plan. The NPS received the following comments regarding cultural resources:

• The NPS should develop education programs focused on cultural history and stewardship to protect 

and enhance the cultural ORVs and provide opportunities for people to develop connections with the 

river and its values.

• The NPS should incorporate historic orchard management into the action alternatives.

• The NPS should consider alternatives to removing the historic Sugar Pine and Ahwahnee Bridges.

• The NPS should protect and enhance Camp A.E. Wood (an archeological resource contributing to the 

eligible Wawona Archeological District) by restoring and interpreting the arboretum.

• The NPS should protect archeological resources by removing infrastructure and visitor uses from 

sensitive areas.

• The NPS should collaborate with culturally-associated American Indian people to protect and 

enhance prehistoric and ethnographic resources.

2012 Spring: Preliminary Alternatives Concepts Workshops

These workshops, site visits, and webinars presented an initial range of preliminary alternative concepts for 

consideration by the public, stakeholders, and internal and external partners. The information provided to the 

public described the process for developing and refining user capacities for the Merced River corridor. The 

NPS received the following comments regarding cultural resources:

• The NPS should retain the Merced Lake High Sierra Camp because it is a significant historic resource.

• The NPS should not remove the historic bridges because of their important value as historic resources. 

If the bridges must be removed, the NPS should relocate them to an area where they will not adversely 

affect other river values.

• The NPS should not remove the historic bridges because their removal would cause additional traffic 

problems on Yosemite Valley roads.

• The NPS should not remove the historic bridges as they provide opportunities for scenic viewing that 

is protective of other river values.

• The NPS should identify additional cultural ORVs, including historically-significant buildings relating 

to inn keeping and hospitality, history of modern rock climbing, and history of concession services in 

Yosemite.

• The NPS should resolve questions about traditionally associated American Indian people in order to 

better understand claims to ancestral homelands and ongoing cultural connections with Yosemite. 

• The NPS should protect and enhance American Indian values.

2013 Winter: Public Release of the Merced Wild and Scenic River Draft Comprehensive 

Management Plan and Environmental Impact Statement

Beginning with release of the draft plan and continuing through the comment period, the NPS conducted a 

series of presentations and listening sessions. The information provided to the public described the process for 

developing the range of alternatives, and the major differences between each alternative. Chapter 9 of the draft 

plan included NEPA and NHPA analyses for each alternative. Additionally, Appendix J presented the NHPA 

assessment of adverse effects of the draft preferred alternative by historic property. The NPS received the 

following comments regarding cultural resources:

• The NPS should implement a conservative approach to analysis of cultural resources until site-specific 

plan design and resource evaluations can be completed.

• The NPS should evaluate the system of High Sierra Camps for National Register eligibility, in addition 

to the existing site-specific evaluations. 

• The NPS should retain historic bridges (i.e. Sugar Pine Bridge) in order to meet obligations under the 

National Historic Preservation Act.

• The NPS should remove the historic bridges in order to restore the valley to a more natural setting.

• The NPS should preserve historic integrity associated with the Merced Lake High Sierra Camp in 

order to meet obligations under the National Historic Preservation Act.

• The NPS should retain and rehabilitate the Superintendent's House and Garage (Residence 1) in place.

• The NPS should remove the Superintendent's House and Garage (Residence 1) rather than relocate it 

to the NPS housing area.

• The NPS should retain the ice rink as a historic resource.

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS J-5
NATIONAL HISTORIC PRESERVATION ACT ASSESSMENT OF EFFECT FOR SITE-SPECIFIC ACTIONS

• The NPS should consider alternatives to demolition of historic buildings, such as relocation or 

rehabilitation, to preserve historic resources and avoid impacts associated with constructing new 

buildings. 

• The NPS should implement preservation of historic resources as a means of providing jobs.

• The NPS should retain its historic structures because their removal is not required under WSRA.

• The NPS should conduct archeological testing to inform design of the new Wawona Fire Station and 

other proposed ground-disturbing actions near the Wawona General Store.

• The NPS should have a Native American Monitor on site when any ground-disturbing activities in the 

Merced River Corridor are located near pre-historic sites.

• The NPS should not construct the proposed Yosemite Lodge/Lower Yosemite Fall pedestrian 

underpass because it could affect culturally-significant resources.

Identification of Consulting Parties

Planning for the Merced Wild and Scenic River has been carried out in consultation with state, federal, and 

local agencies; and tribes and groups associated with the Merced Wild and Scenic River corridor. Consistent 

with 36 CFR Part 800.3(b) and 36 CFR Part 800.8, the review process for Section 106 of the NHPA is conducted 

in coordination with the NEPA review process for the Draft Merced River Plan/EIS. 

Traditionally-Associated American Indian Tribes and Groups

The Yosemite National Park American Indian Consultation Program facilitates regulatory compliance with 

statutes, executive orders, policies, and guidance related to American Indian resources, issues, and concerns. 

The NPS consults with both federally-recognized and federally non-recognized American Indian tribes and 

groups with ancestral connections to Yosemite National Park lands and resources throughout the development 

and implementation of the Merced River Plan. 

Yosemite National Park currently maintains consultative relationships with seven American Indian tribes and 

groups, including five federally-recognized American Indian tribes (Bridgeport Indian Colony, Bishop Paiute 

Tribe, North Fork Rancheria of Mono Indians of California, Picayune Rancheria of the Chukchansi Indians, 

and the Tuolumne Band of Me-Wuk Indians), and two federally non-recognized American Indian groups 

(American Indian Council of Mariposa County, Inc. [also known as the Southern Sierra Miwuk Nation] and the 

Mono Lake Kutzadikaa). Consultation with federally-recognized American Indian tribes takes place on a 

government-to-government basis.

In December 2009, Yosemite requested tribal participation in development of the Merced River Plan. The NPS 

formally requested information from traditionally-associated American Indian tribes and groups for the 

protection of traditional cultural resources and historic properties with traditional cultural or religious 

significance. The NPS will continue to consult with traditionally-associated American Indian tribes and groups 

about proposed NPS plans and actions that have the potential to affect the treatment, use, and access to cultural 

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS J-9
NATIONAL HISTORIC PRESERVATION ACT ASSESSMENT OF EFFECT FOR SITE-SPECIFIC ACTIONS

and natural resources with religious or cultural significance. Tribal consultation included regularly scheduled 

and special meetings, as well as tribal site visits. Comments received from traditionally-associated American 

Indian tribes and groups have been considered throughout the planning process. 

Received through letters, consultation meetings, site visits, and conference calls, comments from the American 

Indian tribes and groups are summarized as follows:

• The preferred alternative will create a new development footprint in Yosemite. Restoration does not 

solve problems if new development takes place elsewhere as a result.

• Avoid impacts to traditional-use areas, archeological resources, and natural resources. Avoid grounddisturbing activities whenever possible.

• Ensure continued access for traditionally-associated American Indians for the practice of traditional 

cultural activities.

• The proposed pedestrian underpass at Yosemite Lodge would potentially disturb a highlysensitive and culturally-significant area. The entire Lower Yosemite Falls area should be protected 

from any further development and ground disturbance.

• The Old El Portal Waste Water Treatment Plant site should be protected from further development 

and increased visitation. Any plans for the site should be developed in consultation with the 

traditionally-associated tribes and groups.

• There is concern that the park is putting visitors' experiences over protection of tribal resources and 

the cultural heritage of traditionally-associated American Indians. 

California State Historic Preservation Officer

The California State Office of Historic Preservation is responsible for administering federal- and statemandated historic preservation programs to protect California's irreplaceable archeological and historical 

resources. Consultation takes place under the direction of the State Historic Preservation Officer (SHPO), a 

gubernatorial appointee. The NPS initiated consultation with the State Historic Preservation Office regarding 

the Merced River Plan/EIS in June 2007. This initial consultation was undertaken in keeping with the 

stipulations of the 1999 Programmatic Agreement among the National Park Service at Yosemite, the California 

State Historic Preservation Office (SHPO), and the Advisory Council on Historic Preservation (ACHP) Regarding 

Planning, Design, Construction, Operations, and Maintenance, Yosemite National Park, California (1999 PA).

Further consultation with the SHPO in June, July, and August of 2012, determined that the standard four-step 

process outlined in 36 CFR Part 800 would be a more appropriate consultation process for this complex 

planning effort, in addition to a 2014 sunset date for the 1999 PA. The NPS will serve as the lead agency on 

behalf of the U.S. Army Corps of Engineers for consultation with the SHPO.

Comments from the SHPO regarding the Merced River Plan and its NHPA consultation process are summarized 

as follows:

• The NPS should prepare, for all consulting parties, a standard Section 106 consultation package 

meeting the documentation standards of 36 CFR Part 800.11.

• The SHPO appreciates the inclusivity of most of the cultural ORVs, such as the inclusion of the entire 

Yosemite Valley Archeological District (YVAD) in ORV 9.

• The entire Yosemite Valley Historic District should be part of ORV 10, which would presumably result 

in greater protection of historic properties (and Cultural ORVs) under WSRA, NEPA, and NHPA 

Section 106.

• Historic structure condition assessments are not an effective measure of the health of cultural ORVs. 

J-10 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS
36 CFR Part 800.3 Initiation of the Section 106 Process (Step 1 of 4)

Instead, the NPS should consider a metric that acknowledges both a resource’s historic integrity and

its physical condition. 

• ‘What the NPS has defined as “localized” adverse effects are still considered adverse effects, under 

both WSRA and Section 106, and avoiding adverse effects should be the NPS’ preferred management 

strategy for historic properties. 

• The proposed relocation of the Superintendent’s House (Residence 1) would be an adverse effect on 

the entire Cultural ORV 10 given the prominence and rarity of the resource, as would the proposed 

removal of Sugar Pine Bridge. These two examples demonstrate that the definition of “adverse effects” 

under WSRA and the “indicators” that trigger management action are not sufficient to protect and 

enhance the cultural ORVs. 

• NPS should consider retaining the Superintendent’s House (Residence 1) in place, and raising it above 

the flood level, in lieu of relocation. 

• The NPS should discuss, with consulting parties, measures to avoid and/or minimize adverse effects

before seeking to consult on mitigation measures to be included in the Programmatic Agreement.

Advisory Council on Historic Preservation

The Advisory Council on Historic Preservation (ACHP) is an independent federal agency that promotes the 

preservation, enhancement, and productive use of the nation's historic resources and advises the President and 

Congress on national historic preservation policy. This agency administers the NHPA's Section 106 review 

process and works with federal agencies to help improve how they consider historic preservation values in their 

programs. For purposes of advising and improving agencies’ actions under Section 106, the ACHP will, at times,

elect to participate in controversial or precedent-setting consultation. It is under these criteria that the ACHP 

has elected to participate in the MRP Section 106 consultations. 

Yosemite initiated consultation with ACHP in May 2008 by notifying the agency that the park intended to 

prepare an Environmental Impact Statement (EIS) to comply with NHPA’s Section 106. At the time the ACHP 

did not indicate that they would consult on this undertaking. Through outreach efforts in 2012 it was evident 

that the complex set of actions in the plan would involve potential for adverse effects to prominent historic 

properties attracting attention and controversy among the public. The ACHP responded in a letter dated 

August 28, 2012, in which they notified the NPS that they would participate in the Section 106 review process in 

accordance with 36 CFR 800.2(b)(1). Their decision to participate is based on Appendix A to 36 CFR Part 800, 

the Criteria for Council Involvement in Reviewing Individual Section 106 Cases, which include cases where 

agency actions may have substantial impacts on important historic properties (criterion 1), or undertakings that 

invoke important questions of policy or interpretation (criterion 2). The ACHP’s letter noted both criteria, and 

highlighted criterion 2 because of the NPS’ requirements to balance potential for adverse effects to historic 

properties with natural resource values under WSRA, as well as the requirements of the Ninth Circuit consent 

decree which required the preparation of the plan itself.

Comments from the ACHP regarding the Merced River Plan and its NHPA consultation process are summarized 

as follows:

• The NPS should revise its alternatives and analyses to better achieve a balance between the natural 

environment and the historic properties that are recognized as ORVs. 

• The Yosemite Valley Bridges Historic District should be considered a component of the cultural ORV

based on their river-related and river-dependent nature as the bridges span the river and owe their 

existence to the presence of the river.

• The NPS should monitor the condition of the historic resources ORV contributing historic properties 

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS J-11
NATIONAL HISTORIC PRESERVATION ACT ASSESSMENT OF EFFECT FOR SITE-SPECIFIC ACTIONS

using metrics for historic integrity. 

• The NPS should provide clear, consistent, concise, illustrated, and complete documentation to 

support a finding of adverse effects has presented obstacles to Section 106 consultation that adequately 

supports Section 106 consultation. Such documentation should include the following: 

• Maps illustrating the segments of the river; the location of all proposed activities in the selected 

alternative; historic property boundaries for buildings, structures, objects, sites, and districts; 

buildings/structures proposed for demolition; and location of new developments and restoration 

activities. 

• A matrix of all proposed activities in the selected alternative; list of historic properties in the APE for 

each activity including eligibility status; list and description of adverse effects to historic properties, if 

any; and conditions for no adverse effects to historic properties. 

• The ACHP recommends that the NPS consider each of the unevaluated historic properties as “eligible 

for the National Register” for purposes of assessing cumulative effects. The ACHP recommends that 

the NPS consider each of the potential for adverse effects to historic properties as an “adverse effect.”

The ACHP recommends that the stipulations of the PA address the following issues: 

• Process for review of individual undertakings – The ACHP recommends that the parties consider 

adopting the process for streamlined review of individual undertakings stipulated in the 2008 

Programmatic Agreement Among the National Park Service (U.S. Department of the Interior), the 

Advisory Council on Historic Preservation, and the National Conference of State Historic Preservation 

Officers for Compliance with Section 106 of National Historic Preservation Act (2008 Nationwide PA). It 

provides a clear and consistent framework for streamlined review of undertakings that are unlikely to 

adversely affect historic properties. Whereas the Nationwide PA stipulates that the NPS will follow the 

Section 106 review process in the implementing regulations (36 CFR Part 800.3-7) for individual 

undertakings with the potential to adversely affect historic properties, the parties may wish to develop 

an alternate process for these reviews and include it in the Merced River Plan PA. 

• The commitment to follow best practices should be included in the PA, and further documentation of the 

best practices should be an attachment to the PA (e.g., best practices for avoiding adverse effects to 

archeological sites in tree removal, trail removal, prescribed fire, vegetation management activities, etc.).

• Design guidelines for new construction in the park – The PA should include the commitment to 

develop and apply design guidelines that will avoid adverse effects related to visual intrusions and 

setting changes associated with new construction. 

• Procedures for mothballing tent cabin structures – The commitment to apply such procedures should be 

included in the PA, and further documentation of the procedures should be an attachment to the PA. 

• Design guidelines and best practices for habitat restoration and revegetation – The PA should 

include the commitment to develop and apply design guidelines and best practices that will facilitate 

opportunities to design enhanced habitats for animals and plants of traditional cultural importance to 

Indian tribes and will avoid direct adverse effects to known archeological sites or sites of traditional

cultural importance to Indian tribes in the construction of such undertakings. 

• Mitigation measures for the sum total of adverse effects of the MRP program. 

National Trust for Historic Preservation

Chartered by Congress in 1949, the National Trust for Historic Preservation is now a privately-funded 

nonprofit organization that works to acquire and administer historic places, provide education and outreach, 

and support direct action to identify and save threatened historic places throughout the United States. On 

August 27, 2012, the NPS accepted the National Trust for Historic Preservation (NTHP) request to serve as a 

consulting party in the Section 106 process for the Merced River Plan. The NTHP was included on the project’s 

J-12 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS
36 CFR Part 800.3 Initiation of the Section 106 Process (Step 1 of 4)

mailing list, participated in various consultation meetings and site visits in 2012 and 2013, and was sent hard 

copies of public review documents and notification of public involvement opportunities. The NTHP has also 

been instrumental in the development of the plan-specific programmatic agreement and consultation efforts to 

identify measures to avoid, minimize, and mitigate adverse effects to historic properties.

Comments from the NTHP can be summarized as follows:

• The NPS should revise the boundary of the Historic Resources ORV (ORV 10) to include all of the 

historic resources in the Yosemite Valley Historic District, and establish its definition to be flexible and 

include any resources in its boundaries that are later found to be eligible as contributing resources. 

• The NPS should revise the management standard for ORV 10 to encourage the retention of historic

resources. 

• The NPS should retain the Sugar Pine Bridge, as the reasons cited in the MRP for its demolition are 

unsubstantiated by the offered scientific evidence.

• The NPS should rehabilitate Residence 1 in its current historic location, and make modifications that 

allow for the continued use or adaptive use of the approximately 100 other historic properties slated 

for demolition in the draft preferred alternative. 

Historic Bridge Foundation

The Historic Bridge Foundation is a nonprofit organization that advocates for the preservation of historic 

bridges in the United States by sharing information, supporting education, and participating in consultation 

with public officials to devise reasonable alternatives to demolishing or adversely affecting historic bridges. On 

August 23, 2012, the NPS accepted the Historic Bridge Foundation (HBF) request to serve as a consulting party 

in the Section 106 process for the Merced River Plan/EIS. The HBF has been included on the project’s mailing 

list, participated in various consultation meetings in 2012 and 2013, and were sent hard copies of public review 

documents and notification of public involvement opportunities. The HBF has also been instrumental in the 

development of the plan-specific programmatic agreement and consultation efforts to identify measures to 

avoid, minimize, and mitigate adverse effects to historic properties.

Comments from the Historic Bridge Foundation are summarized as follows:

• The resources identified in the historic resources ORV have been inadequately discussed in the EIS,

and the expected adverse effects to these properties are collectively more damaging than adverse 

impacts to other ORVs.

• The historic bridges of Yosemite should be considered as irreplaceable treasures of the park and 

treated with the utmost respect.

• The information presented regarding Sugar Pine Bridge does not provide satisfactory analysis or 

adequate substantiated evidence to justify the removal of the historic bridge.

• Additional research and revision of the management strategies for ORV 10 must occur to encourage 

retention of the historic resources in the Yosemite Valley Historic District and the Yosemite Valley 

Bridges Historic District, and to understand the cumulative harm to these properties given that they 

enhance the values of the Merced River and the park itself.

(STEP 2 OF 4) 

Area of Potential Effects

The Area of Potential Effects (APE) as defined for this undertaking is 1.5 miles on either side of the Merced 

River’s ordinary highwater mark. The full complement of historic properties that have the potential to be 

effected by actions proposed in the plan, both within and outside the river corridor boundary (per WSRA, 

1⁄4 mile on either side of the ordinary highwater mark) are included in the APE. The NPS received concurrence 

from the State Historic Preservation Office (SHPO) on the APE in a letter dated Sept 17, 2012. 

Historic Properties within Area of Potential Effects

The assessment of effects to historic properties presented in this report includes all historic properties located 

within the APE that are either listed, eligible, or have been identified for listing in the National Register of 

Historic Places. 

Historic properties that may require an assessment of their historical significance include Yosemite Lodge, 

Housekeeping Camp, resources with cultural or religious significance to American Indian tribes and groups in 

Yosemite Valley and El Portal, Hennessey’s Ranch, Standard Oil Bulk Fuel Operations, Rancheria Flat Mission 

66-Era Housing, other potential historic resources in Wawona, and 472 archeological sites that have not been 

evaluated for National Register eligibility. Maps of individual properties potentially affected by the undertaking 

are included in Exhibit 1 of this report. Photos of individual properties are included as Exhibit 2 of this report. 

A good faith effort to identify and evaluation historic resources per 36 CFR Part 800.4(b) and 800.4(c) and 

800.5(a)(3) has been made by the National Park Service to present and will continue. Please see Exhibit 3 for a 

summary of recent efforts to identify and evaluate historic properties and for a comprehensive digital library of 

Yosemite National Park historic properties listed on the National Register, please visit the park web site 

(http://www.nps.gov/yose/historyculture/nr-yose-list.htm) to view the full nomination forms. In addition, 

Exhibit 4 provides summary information for all listed, eligible and identified historic properties within the APE. 

Buildings, Structures, Sites, and Districts 

Buildings, Structures, and Sites

The Historic Resource Study (NPS 1987) is the park’s primary baseline document for identifying historic 

buildings, structures, and sites at a parkwide scale. Other major resource studies and documentation efforts 

have provided new information and more detailed resource-specific data for identifying and documenting 

historic properties in the major developed areas of Yosemite Valley, Wawona and El Portal. These include a 

multiple property document, cultural landscape inventories, and historic property nominations.

While some gaps remain, efforts to identify historic buildings, structures and sites are largely complete. Notable 

needs include mid-century modern resources such as the Yosemite Lodge complex and Housekeeping Camp, 

and buildings and structures in the El Portal area that are 50 years old or older, but have yet to be evaluated. 

These gaps will be addressed as noted under Recent Efforts to Identify Historic Resources below.

J-14 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS
36 CFR Part 800.4: Identification of Historic Properties 

(Step 2 of 4)

Districts and National Historic Landmarks

Districts and National Historic Landmarks have been documented within the APE for the Merced River Plan 

undertaking as part of earlier efforts to identify historic properties. Currently these include historic districts 

and archeological districts. The park will continue to identify districts in consultation with SHPO and 

traditionally-associated American Indian tribes and groups as part of ongoing consultation. The APE includes 

eligible, Listed and not yet evaluated historic and archeological districts, and National Historic Landmarks: 

• Merced Lake High Sierra Camp Historic District (Eligible 2004)

• Segment 1 Archeological Resources (not evaluated)

• Yosemite Valley Historic District (Listed 2006)

• Yosemite Valley Archeological District (Listed 1976)

• Yosemite Village Historic District (Listed 1974)

• Camp Curry Historic District (Listed 1979)

• Yosemite Lodge Historic District (not evaluated)

• Housekeeping Camp Historic District (not evaluated)

• Yosemite Valley Bridges Historic District (Listed 1977)

• The Ahwahnee Hotel (NHL) (Designated 1987)

• The Rangers’ Club (NHL) (Designated 1977)

• LeConte Memorial Lodge NHL (Designated 1987)

• Yosemite Valley Historic properties with Religious and Cultural Significance to American Indians (not 

evaluated)

• Merced Canyon Travel Corridor Historic District (Eligible 1997)

• El Portal Archeological District (Listed 1976)

• El Portal Historic properties with Religious and Cultural Significance to American Indians (not 

evaluated)

• Wawona Archeological District (Eligible1978)

• Wawona Hotel and Thomas Hill Studio, NHL (Listed 1987) and Wawona Hotel and Pavilion Historic 

District (Listed 1975)

Archeological Resources

Efforts to identify archeological properties through systematic archeological inventory varies by river segment. 

This coverage ranges from 70% in Yosemite Valley to 10% of the wild segment above Wawona. Given the 

limitations of identification, and the relatively common discovery of buried archeological deposits, additional 

survey and subsurface testing for archeological resources may be necessary prior to implementation of 

particular actions. 

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS J-15
NATIONAL HISTORIC PRESERVATION ACT ASSESSMENT OF EFFECT FOR SITE-SPECIFIC ACTIONS

Historic Properties with Religious and Cultural Significance to Traditionally-Associated 

American Indian tribes and Groups

Many known and unknown historic properties within the Merced River corridor in Yosemite National Park 

and the El Portal Administrative Site hold religious and/or cultural significance to traditionally-associated 

American Indian peoples. Through professional ethnographic studies and government-to-government 

consultation with American Indian tribes, the National Park Service has identified the presence of historic 

properties with religious and cultural significance to American Indian tribal groups that are separate and 

distinct from the Yosemite Valley Archeological District. A continued commitment to hosting site visits and 

engaging tribal partners in discussions during project formulation for Merced River Plan actions will ensure 

efforts are made to avoid adverse effects to resources with religious and/or cultural significance. The NPS and 

American Indian tribes and groups will continue to collaborate on resources management and historic 

preservation activities guided by existing cooperative agreements to ensure that adverse effects to historic 

properties with traditional religious and cultural significance can be avoided.

Throughout the Merced River planning process the National Park Service has made a reasonable effort to 

identify traditional cultural properties through numerous consultation workshops, site visits, and distribution 

of working drafts of the plan’s components. During these consultation efforts the park has worked with groups 

and individuals who have special knowledge and interests in the history and cultural of the Merced River 

corridor. Specifically, comprehensive project and action lists have been distributed to consulting tribes and 

groups and many locations within the APE have been visited by tribal partners and park staff to discuss actions 

and the potential impacts to resources (i.e., meadows, riparian areas, black oak woodlands, etc) or effects to 

historic properties with or without religious and/or cultural significance. Tribal partners have provided written 

feedback on the Draft Merced River Plan / EIS and the Draft Section 106 Report, and during consulting party 

review and preparation of the draft Final Section 106 Report.

The National Park Service has a consultative relationship with traditionally-associated American Indian tribes 

and groups independent of the consultation required on historic properties under the National Historic 

Preservation Act. The park has numerous cooperative agreements with tribes and groups that articulate the 

commitments the respective parties have, for example, made regarding consultation activities, annual 

traditional events and ceremonies in the park, and monitoring requirements during archeological investigations 

and/or construction projects. 

The plan proposes to address information gaps for the Yosemite Valley, El Portal, and Wawona Archeological 

Districts as part of efforts to identify and document historic properties with religious and cultural significance 

to traditionally-associated American Indian tribes and groups throughout the duration of plan implementation.

36 CFR PART 800.5: ASSESSMENT OF ADVERSE EFFECTS (STEP 3 OF 4) 

Under Section 106 of the National Historic Preservation Act (NHPA), once historic properties have been 

identified in an undertaking’s area of potential effect, and it has been determined that those historic properties 

may be affected by a proposed undertaking, the agency official shall assess the effects on those resources in 

accordance with 36 CFR Part 800.5 Assessment of adverse effects. An adverse effect is found when an 

“undertaking may alter, directly or indirectly, any of the characteristics of a historic property that qualify the 

property for inclusion in the National Register in a manner that would diminish the integrity of the property's 

location, design, setting, materials, workmanship, feeling, or association”(36 CFR Part 800.5[a][1]). The criteria 

of adverse effect are applied to all historic properties (listed, eligible, or identified) within the APE, with 

consideration given to all qualifying characteristics of a historic property, including those that may have been 

J-16 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS
36 CFR Part 800.5: Assessment of Adverse Effects (Step 3 of 4)

identified subsequent to the original evaluation of the property's eligibility for the National Register. 

After making an initial assessment of effect, the NPS has worked with consulting parties to determine if the 

assessment reflects all relevant or applicable concerns, developed and evaluated modifications to the Merced 

River Plan undertaking that could avoid, minimize or mitigate adverse effects (36 CFR Part 800.6(a)). 

Application of the criteria of adverse effect has been consulted on with the SHPO, ACHP, traditionallyassociated American Indian tribes and groups, and other consulting parties. The NPS has considered views 

provided by consulting parties and the public concerning the effects of the Merced River Plan undertaking in 

accordance with [36 CFR Part 800.5(a)]. 

A plan-specific Programmatic Agreement (Appendix I of the Final Merced River Plan/EIS) documents the 

concurrence on the assessment of effects of the Merced River Plan undertaking and guides the process for 

future consultation. Avoidance, minimization, and mitigation measures will be developed through subsequent 

project-specific agreements in consultation with SHPO, ACHP, traditionally-associated American Indian tribes 

and groups, and the public as appropriate. 

Criteria for Adverse Effects

Actions that result in an assessment of adverse effects to historic properties include, but are not limited to (36 

CFR Part 800.5(2)): 

(i) Physical destruction of or damage to all or part of the property;

(ii) Alteration of a property, including restoration, rehabilitation, repair, maintenance, stabilization, 

hazardous material remediation and provision of handicapped access, that is not consistent with 

the Secretary of the Interior’s Standards for the Treatment of Historic Properties (36 CFR Part 

68) and applicable guidelines; 

(iii) Removal of the property from its historic location;

(iv) Change of the character of the property’s use or of physical features within the property's setting 

that contribute to its historic significance;

(v) Introduction of visual, atmospheric or audible elements that diminish the integrity of the 

property's significant historic features;

(vi) Neglect of a property which causes its deterioration, except where such neglect and deterioration 

are recognized qualities of a property of religious and cultural significance to an Indian tribe or 

Native Hawaiian organization; and

(vii) Transfer, lease, or sale of property out of Federal ownership or control without adequate and 

legally enforceable restrictions or conditions to ensure long-term preservation of the property's 

historic significance.

According to the regulations, “adverse effects may include reasonably foreseeable effects caused by the 

undertaking that may occur later in time, be farther removed in distance or be cumulative” (36 CFR Part 

800.5(a)(1)). The National Park Service has clearly and thoroughly described the Merced River Plan 

undertaking. While the implementation of the undertaking will proceed over the next 20 years, relatively all 

actions are site-specific and described in the Final Merced River Plan / EIS. Therefore, when determining 

adverse effects, the NPS has accounted for all actions in the undertaking and has presented the cumulative 

assessment of these actions for each district within the APE.

The following tables present an assessment of effects for the actions of the Merced River Plan undertaking

relative to historic properties within the APE. These actions have been broken into three primary assessment of 

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS J-17
NATIONAL HISTORIC PRESERVATION ACT ASSESSMENT OF EFFECT FOR SITE-SPECIFIC ACTIONS

effects categories: Category 1 – No Historic Properties Affected or No Adverse Effect, Category 2 – Adverse 

Effect, and Category 3 – Identification, Evaluation, and/or Assessment of Effects to be Determined.

Category 1 – No Historic Properties Affected or No Adverse Effect

No Historic Properties Affected – An assessment of “no historic properties affected” is found for projects that 

would not affect historic properties either by nature of the action or because the location of the action does not 

intersect physically with the historic property. 

No Adverse Effect – An assessment of “no adverse effect” is found for projects that would not alter, directly or 

indirectly, any of the qualities of a historic property that qualify the property for inclusion in the National 

Register in a manner that would diminish the integrity of the property’s location, design, setting, materials, 

workmanship, feeling, or association. The NPS and American Indian tribes and groups will continue to 

collaborate on resources management and historic preservation activities guided by existing cooperative 

agreements to ensure that adverse effects to historic properties with traditional religious and cultural 

significance can be avoided.

Category 2 – Adverse Effect

An “adverse effect” is found when an undertaking may alter, directly or indirectly, any of the characteristics of a 

historic property that qualify the property for including in the National Register in a manner that would 

diminish the integrity of the property’s location, design, setting, materials, workmanship, feeling, or association. 

Category 3 – Identification, Evaluation and/or Assessment of Effect to be Determined

The NPS in good faith, will make a reasonable effort to carry out appropriate identification and evaluation 

efforts in accordance with Section 110 of the National Historic Preservation Act and 36 CFR 800.4 as needed 

prior to assessment of effects. Category 3 actions also include those that need additional project-level detail 

prior to an assessment of effects being made determined. As project-level details are developed, the NPS in 

consultation with SHPO, ACHP, traditionally-associated American Indian tribes and groups, and other 

consulting parties as appropriate and shall seek ways to resolve adverse effects. 

The NPS will carry out all identification, evaluation, assessment of effects, and consultation requirements in 

accordance with 36 CFR Part 800 and the 2008 Programmatic Agreement Among the National Park Service (U.S. 

Department of the Interior), the Advisory Council on Historic Preservation, and the National Conference of State 

Historic Preservation Officers for Compliance with Section 106 of the National Historic Preservation Act.

the park lands that he was charged to manage. 

LeConte Memorial Lodge NHL (Designated 1987)

The LeConte Memorial Lodge NHL will not be affected by the Merced River 

Plan undertaking. The significance of the NHL and districts would still convey 

the influential Sierra Club in the Sierra Nevada Mountains, architecture with

strong European roots in its Tudor Revival design, and interesting use of building 

materials found in the work of architects of the Bay Area tradition. 

Yosemite Valley Historic properties with Religious and Cultural 

Significance to American Indians (not evaluated)

Though identified – but not yet evaluated – historic properties with religious and 

cultural significance to American Indians will continue to convey relatively 

contiguous and interrelated places that are inextricably and traditionally linked 

to the history, cultural identity, beliefs, and behaviors of contemporary and 

traditionally-associated American Indian tribes and groups. These areas include 

traditional-use areas, spiritual sites, archeological resources, and historic village 

sites that are rooted in the history of traditionally-associated peoples and are 

important to maintain and continue their cultural identity.

Merced Canyon Travel Corridor Historic District 

(Eligible 1997)

Adverse effects to the Merced Canyon Travel Corridor Historic District would 

result from introduction of non-historic features through paving and formalizing 

roadside pullouts, and installing curbing and culverts between Pohono Bridge 

and the intersection of the Big Oak Flat Road and removal of abandoned 

infrastructure associated with the Civilian Conservation Corps camp at Cascades 

Picnic Area. However, the district’s significance would be retained as a travel 

route from El Portal to Yosemite Valley that has been used for at least the past 

2,000 years. Minimization and mitigation of adverse effects would be addressed 

though project-specific agreements.

Actions that cumulatively affect the Merced Canyon Travel Corridor

• Formalize roadside parking and river access points between Pohono 

Bridge and Big Oak Flat Road/El Portal Road intersection. (No Adverse 

Effect)

El Portal Archeological District (Listed 1976)

Adverse effects to the El Portal Archeological District could result from ground 

disturbance that could affect intact deposits of archeological sites within the 

district. However, the district’s significance would be retained because significant 

sites, perhaps as old as 9,500 years, will still contain data important to interpreting 

early settlement patterns, some of the best-preserved archeological resources 

from the protohistoric period, American Indian cultural change as a result of 

contact with Euro-Americans, and prehistoric village sites. These resources are 

exceptional in their significance to local American Indian communities. 

Avoidance, minimization and mitigation of adverse effects would be addressed 

though project-specific agreements.

Actions that cumulatively affect the El Portal Archeological District:

• Various El Portal protection actions for archeological sites (CA-MRP0250/H and 0251/H) (No Historic Properties Affected)

El Portal Historic properties with Religious and Cultural 

Significance to American Indians (not evaluated)

cultural significance to American Indians will continue to convey relatively 

contiguous and interrelated places that are inextricably and traditionally linked 

to the history, cultural identity, beliefs, and behaviors of contemporary and 

traditionally-associated American Indian groups. These areas include traditionaluse areas, spiritual sites, archeological resources, and historic village sites that are 

rooted in the history of traditionally-associated peoples and are important to 

maintain and continue their cultural identity.

Wawona Archeological District (Eligible1978)

Adverse effects to the Wawona Archeological District include relocating the 

dump station, and replacing the septic system at Wawona Campground with a 

pump station and connection to the central wastewater treatment facility, 

replacement of restrooms, construction of a bus stop, expansion of the picnic 

area and hardening river access points in the Wawona Store area, visitor access 

and restrooms developed at the Swinging Bridge area, relocation of the Stock 

Campground, a redesigned maintenance area, and construction of a Wildland 

Fire Station. Ground disturbance may affect up to seven individual sites out of 

100 archeological sites within the district. However, the district’s significance 

would be retained because significant sites will still have the ability to provide 

information pertaining to American Indian subsistence strategies, seasonal use of 

specific ecological zones, and demographic patterns for both prehistoric and 

historic-era occupation of the area. Minimization and mitigation of adverse 

effects would be addressed though project-specific agreements.

Actions that cumulatively affect the Wawona Archeological District:

• Construct pump station and utility corridor connecting the Wawona

No adverse effects within the Wawona Hotel and Thomas Hill Studio, NHL nor 

the Wawona Hotel and Pavilion Historic District would result from the Merced 

River Plan undertaking. The significance of the NHL and districts would still 

convey the largest existing Victorian-style hotel complex within the boundaries 

of a national park with a high-level of integrity.

TRAN-2-005 Yosemite Lodge: pedestrian / 

vehicle conflicts on Northside 

Drive

A tiered NEPA / NHPA compliance effort (EA/Section 106 

Determination) will evaluate a range of alternatives to address 

the pedestrian / vehicle conflicts on Northside Drive between 

the Yosemite Lodge Area and the Lower Yosemite Fall Area. 

The final preferred alternative will include design guidelines to 

ensure that archeological impacts are avoided or minimized; 

the alignment of the crossing keeps pedestrians on the 

pathways and reduces the temptation to cross the road ongrade; the safety of pedestrians is maximized; and visual 

impacts are minimized.

Identification, evaluation and assessment of effects to be 

determined for district and Yosemite Lodge that may 

result from addressing the pedestrian / vehicle conflicts

Yosemite Lodge Determination of Eligibility (2014)

The park is in the initial stages of determining the eligibility of the Yosemite Lodge Complex (the Lodge) for 

the National Register of Historic Places. Originally constructed in 1915, the Lodge was re-built as part of 

"Mission 66," a national park service-wide effort to upgrade or build new visitor facilities in honor of the 

50-year anniversary of the founding of the National Park Service. As characteristic Mission 66 buildings 

approach 50 years of age, they can be considered for eligibility to the National Register. Yosemite Lodge 

displays many of the features that are emblematic of Mission 66 style: Mid-Century Modern architectural 

style including numerous large windows to afford views of the surroundings and an open interior space. 

El Portal Administrative Site Historic Resource Survey with Assessments and 

Recommendations (draft 2011)

The El Portal Administrative Site Historic Resource Survey with Assessments and Recommendations (draft 

2011) provides background for development of the Merced River Plan/EIS. However, it also useful for 

improving our understanding the cultural resources in the El Portal area. The report discusses potential 

historic resources within the district and suggests future actions, such as completion of determinations of 

eligibility for listing in the National Register of Historic Places (National Register), nominations to the

National Register, or creating management plans that acknowledge and retain the historic resources of the 

administrative site.

Wawona Hotel and Meadow Cultural Landscape Inventory (Draft CLI)

The Wawona Hotel and Meadow Cultural Landscapes Inventory is currently in the final stages of preparation

for submittal as a consensus determination of eligibility to SHPO. This report will provide a comprehensive 

inventory and analysis of the cultural landscape that includes and surrounds the Wawona Hotel, which is 

both a National Historic Landmark (NHL) and a historic district. The boundary of the CLI includes the 

Wawona Golf Course on the hotel's west side and the Wawona Meadow, which is adjacent and south of the 

hotel. Also in the CLI boundary is the Washburn Ditch, a 2.7 mile ditch generally following the course of the 

Merced River constructed to supply water to the Wawona complex. The CLI builds on the existing national 

register and national landmark documentation by defining and evaluating the setting and environmental 

context for the historic property. The period of significance for the cultural landscape is from 1876 to 1939.

Wawona Basin Cultural Landscape Inventory (Draft CLI)

The NPS began work on a Cultural Landscape Inventory for the Wawona Basin in order to systematically 

identify and evaluate the historic resources in the Wawona Basin, which is roughly 501 acres and includes all 

historic developments in the area: the Wawona Hotel & Meadow, and the Pioneer Yosemite History 

Center, as well as Civilian Conservation Corps (CCC)-era developments along Chilnualna Falls Road 

Corridor and the Maintenance Area. A draft report was prepared but not finalized. In the course of 

conducting the research, the NPS determined that the resources did not in fact represent a historic district. 

The CLI built on the existing national register and national landmark documentation to further document 

the surrounding landscape (or setting) and associated landscape features in order to provide the 

environmental context for understanding the significance of the Wawona development. Although the sum 

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS J-69
NATIONAL HISTORIC PRESERVATION ACT ASSESSMENT OF EFFECT FOR SITE-SPECIFIC ACTIONS

of the resources in the area did not rise to the level necessary for listing as a cohesive historic district, this 

project did document the existence and integrity of a number of buildings, particularly those related to CCC 

projects in the Wawona area, such as the ranger station on Chilnualna Falls Road. The findings are in draft 

form and will be finalized and forwarded to the SHPO’s office for review and concurrence.

Archeological Sites Baseline Documentation (Darko 2011)

This report details the baseline site documentation for archeological sites within the Merced Wild and 

Scenic River corridor and the National Register of Historic Places (NRHP) districts of Wawona, Yosemite 

Valley, and El Portal. The work was completed as a data gathering effort in support of the Merced River 

Plan/EIS. It focused on bringing archeological site documentation (219 sites) up to current standards, and 

obtaining current condition information for sites in these three areas of the Merced Wild and Scenic River 

corridor. The site documentation was completed by the park’s Division of Resources Management and 

Sciences, Branch of Anthropology, between October 2010 and February 2011.

Assessment of Pack Stock Impacts at Archeological Sites in the Upper Merced River 

Basin (Wills 2011)

This report describes the archeological work in the upper Merced Wild and Scenic River corridor basin, 

and was completed as part of the planning process for the Merced River Plan/EIS. The main purpose of this 

study was to assess the condition of archeological resources and quantify physical impacts of pack stock use 

on those resources in the vicinity of high elevation meadows and campsites. This research contributes to a 

larger condition assessment of meadows in the river corridor, completed by the park’s Division of 

Resources Management and Sciences, Branch of Vegetation and Ecological Restoration (VER. The study 

targeted areas between the top of Nevada Fall and the 10,000 ft elevation band, and included resources 

along the main stem of the Merced River, as well as the Triple Peak and the Lyell Forks. The study was 

completed by the park’s Division of Resources Management and Sciences, Branch of Anthropology, 

between October 2010 and February 2011. 

Annual Condition Assessments and Site Record Updates 

Annually, the NPS conducts several archeological site condition assessments and database record updates 

as part of work under the Pacific West Region Corrective Action Plan. These condition assessments include 

identification of primary threats and disturbances; deferred maintenance needs; recommendations for 

periodic monitoring, preservation and protection treatments; and planning tools for archeological 

interpretation, visitor use, and visitor safety. The primary goal of this work is to assess the site conditions 

for all sites with condition assessments conducted more than 10 years ago, as well as update site record 

entries in the standardized database (the NPS’ Archeological Sites Management Information System, or 

ASMIS).

Synthesis of El Portal Archeological Data for NAGPRA 

The intent of this project is to carry out consultation and research activities necessary to accomplish 

objectives specific to the Native American Graves Protection and Repatriation Act (NAGPRA) for the 

inadvertent discovery of human remains and other cultural items resulting from unauthorized excavations 

at CA-MRP-250/H, and other intentional excavations and inadvertent discoveries at CA-MRP-181/H, both 

J-70 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS
Exhibit 3: Recent Efforts to Identify Historic Resources

in the El Portal Administrative Site of Yosemite National Park. The goal of this two-year project is for the 

principal investigator and other collaborators attached to the project to work in collaboration with NPS 

subject-matter specialists to achieve compliance with NAGPRA. Government representatives will conduct 

consultation with all traditionally-associated American Indian tribes and groups, and require collaborative 

research to address the question of cultural affiliation for these human remains and cultural materials, 

development of a written plan of action for the intended disposition of the human remains and cultural 

items, and publication of the required Notices of Intended Disposition. This project is still in progress.

Finalize Major Wawona Backlog Archeological Report and Site Records

Investigators from the University of California at Merced (UCM) and NPS will collaborate to complete the 

analysis, reporting, and archiving of major archeological collections from the Wawona and Yosemite Valley 

areas. The reports are expected to do the following:

• Provide a platform for further archeological study in both Wawona and Yosemite Valley, 

• Provide information to tribal partners on the archeological aspects of American Indian heritage, 

and 

• Serve as a basis for educating park visitors and students. 

The Yosemite Archeology Program has generated large-scale collections of archeological materials from the 

Wawona Basin and Yosemite Valley during the mid-1980s and mid 2000s field seasons, important 

collections that require systematic analysis and reporting. For example, over 300 artifact lots were recovered 

at Wawona during work at 42 archeological sites. The first phase of work will include systematically 

analyzing the artifacts, updating the Yosemite archeology databases, completing a technical report, 

preparing detailed maps of the work and site areas, and archiving the materials in the Yosemite Museum. 

The second phase entails completing the scientific study and reporting for materials collected at a significant 

prehistoric and historic-era Indian village in Yosemite Valley. Both phases of work will be accomplished by 

Yosemite archeology staff, in collaboration with Dr. Kathleen Hull of UCM.

Testing at CA-MRP-0008/H for Wawona Fire Station Design and Development

The Wawona Fire Station is being proposed in the Merced River Plan/EIS undertaking to consist of the 

construction of a 6,500 square foot combined wildland and structural fire station near the Wawona 

Maintenance area. Preliminary design for construction of the new fire station assumes approximately 12-16 

inches of fill over archeological resources and excavation up to 12 inches into existing soil. Two utility 

trenches measuring approximately 24 inches deep by 18 inches wide will also need to be excavated to 

provide connections from the new building to the main line. An archeological investigation conducted in 

July 2013 provides information to identify presence or absence of potentially-eligible archeological 

resources prior to this undertaking, assess the effects of proposed actions on those properties, and examine 

design alternatives to avoid or mitigate effects.

The ranch house included accommodations for paying guests who were 

usually on their way to Yosemite Valley. The ranch included berries, 

grapes, a vegetable garden, and an orchard of fruit trees, some of which 

still exist. All that is left currently, besides some of the orchard, are some 

stone remnants and the graves of his mother and an unknown traveler 

at the site of the ranch.

Rancheria are typical of Mission 66-style architecture. They were built 

from standard plans designed by the NPS Branch of Architecture to 

create efficient, utilitarian housing that gives these homes a particularly

El Portal 

Archeological 

District

District Listed 1976 Local, 

Regional 

Sites have intriguing evidence of use, perhaps as old as 9,500 years, and 

contain data important to interpreting early settlement patterns (Hull 

and Morratto 1999). Most sites date to between 2500BC and AD 1900, 

with several 19th- and 10th-century homesteads and settlements by 

American Indians. The El Portal Archeological District may contain some 

of the best-preserved archeological resources from this protohistoric 

period reflecting American Indian cultural change as a result of contact 

with Euro-Americans (Moffitt and Anderson 1976). Although land use in 

the early and mid-20th century has altered the landscape and affected 

archeological deposits in many places, a great deal could be learned 

from the remaining resources. Despite the loss of some information, the 

original extent and complexity of the sites, especially the prehistoric 

village sites, indicate that valuable information is still available. 

Archeological resources in the El Portal Archeological District represent 

an important source of data on the growth of the area as a national 

park, as well as on the cultural transition experienced by American 

Indian communities during Euro-American settlement. In addition, these 

resources are exceptional in their significance to local American Indian 

communities.

District

District Eligible1978 Local, 

Regional

The district is 4,940 acres in size, spanning Segments 5 to 8, and 

includes at least 74 archeological sites (Hammack and Anderson 1978, 

Darko 2011), many of which are located within the South Fork Merced 

River corridor. The importance of this eligible district documented in 

1978 lies in its ability to provide information pertaining to American 

Indian subsistence strategies, seasonal use of specific ecological zones, 

demographic patterns, and both prehistoric and historic-era occupation 

of the area (Hammack and Anderson 1978). It is likely that some sites in 

this district also possess additional significance not recognized at the 

time of their determination of eligibility, both in terms of archeological 

information potential and religious or cultural significance to associated 

American Indian tribes and groups. In addition, material cultural remains 

of previously under-reported ethnic groups such as African American 

and Chinese American are important. Historical contexts for these kinds 

of resources have yet to be developed. While not reflected in the existing 

National Register nominations, the NPS recognizes ethnicity as an aspect 

of significance to the Wawona Archeological District.

RES-AS002All Non-historic 

informal trails

Non-historic informal trailing in 

meadows is common, particularly 

in Yosemite Valley. Non-historic 

informal trails lead to direct 

impacts such as soil compaction 

and vegetation trampling and 

may have indirect impacts such as 

changes to hydrology and soil 

moisture, a decrease in habitat 

quality, and the introduction of 

non-native species.

Non-historic informal trailing will 

be removed and restored to 

natural conditions. Fencing and 

signage will be used to direct 

traffic to less sensitive areas that 

can accommodate some use 

without compromising meadow 

health. Through the use of 

closure signs, fencing, and/or

rocks and logs these trails will be 

better defined and delineated.

Convert area to designated 

Wilderness. 

Convert Merced Lake High Sierra 

Camp to a temporary pack camp 

with a maximum of 15 people 

allowed. Remove all permanent 

infrastructure. Convert area to 

designated Wilderness. Establish 

a maximum limit of 2.5 pack 

strings-per-week for re-supply of 

the temporary outfitter camp for 

each season.

historic canvas tents that are 

removed and retain the 

configuration of the remaining 11 

historic canvas tents (possibly 

remove every other tent to 

maintain the “u” shape of the 

camp).

Synergistic effects of many 

factors, including natural 

selection and past human 

actions, have led to changes in 

Yosemite Valley plant 

communities that are ecologically 

connected to the meadow and 

riparian ecosystem of the Merced 

River. Changes in plant 

communities include increasing 

conifers, denser canopy covers, 

and high fuel loading.

re-vegetation, prescribed fire, 

mechanical removal of conifers, 

and re-design of infrastructure. 

These actions will enhance scenic 

vistas and maintain the cultural 

landscape, as well as enhance the 

condition of the Merced River 

ecosystem by sustaining the

RES-2-008 2 Stoneman Meadow

parking lot: road 

through meadow 

and parking lot

Stoneman Meadow is bisected by

Southside Drive. The elevated 

road prism disconnects surface 

and groundwater within the 

meadow. This impacts the high 

water table, which is critical to 

maintain the integrity of meadow 

habitat. Curry Village orchard 

parking area is in what was 

formerly Stoneman Meadow, 

which has an impact on the

RES-2-009 2 El Capitan Meadow: 

non-historic 

informal trails, 

bisected by road, 

conifer 

encroachment

Climber use trails bisect El 

Capitan Meadow on the north 

side. Non-historic informal trails 

through the meadow and 

associated oak woodland lead to 

vegetation trampling and soil 

compaction. Water pools on the 

north side of the road, blocking 

water flows between the 

adjacent cliff walls and the 

meadow. Conifer saplings are 

encroaching on the meadow, 

resulting in the loss of meadow 

habitat. Roadside parking 

remains curbed to prevent 

encroachment on meadow.

Reroute climber use trails on 

north side of road from meadow 

habitat to an appropriate upland 

route (a few meters to the east). 

Remove non-historic informal 

trails through meadow and oak 

woodland. Protect re-vegetated 

areas with fencing or other 

natural barriers and sign the area 

to reduce trampling of sensitive 

meadow vegetation. As 

opportunities arise through 

maintenance or restoration 

projects, improve hydrologic flow 

and meadow connectivity by 

extending the permeable road 

base across the entire segment of 

Northside Drive through El 

Capitan Meadow and add 

additional box culverts with 

bottom elevations equal to the 

meadow surface elevation. 

Remove conifer saplings 

encroaching on meadow habitat.

Soil compaction and trampled 

vegetation would continue to 

exist due to non-historic informal 

trails and easy access to the 

meadow from roadside parking. 

Continue to remove invasive nonnative plants following the 

Invasive Plant Management Plan 

and continue with prescribed fire 

following the Fire Management 

Plan, including mechanical 

removal of conifer saplings to 

reduce fuel load. 

Remove all non-historic informal 

trails and areas of bare 

compacted soils and restore to 

native plant communities. 

Disperse and reduce roadside 

parking along the meadow 

through alternative pavement 

striping (approximately 30 spaces 

removed). Retain some roadside 

parking for SAR and other 

administrative traffic. Use 

restoration fencing and signing 

where necessary to further 

protect the meadow from 

trampling.

Remove all non-historic informal 

trails from the meadow that 

incise, promote habitat 

fragmentation, or are located in 

sensitive and frequently 

inundated areas, and restore to 

natural condition. Use restoration 

fencing and signing to designate 

appropriate meadow access 

points.

Remove all non-historic informal

RES-2-010 2 Bridalveil Meadow: 

stream headcutting 

and absence of 

willows

A deep headcut from a former 

ditch remains adjacent to Bridalveil 

Meadow, which subsequently 

causes meadow dewatering and 

heavy downstream erosion. 

Willows were once abundant in 

Bridalveil Meadow. They do not 

easily regenerate after wholesale 

removal and thus the meadow has 

remained without willows for over 

a century, resulting in less 

biological diversity in the meadow.

Treat by inserting live willow 

cuttings into the headcut area, 

river bank and adjacent meadow.

west edge of meadow by 

planting willow cuttings in the 

impacted area, along riverbank,

RES-2-023 2 Housekeeping 

Camp: riparian 

restoration and river 

access

Several Housekeeping Camp 

units are located in the 2- to 10- 

year floodplains, impeding 

hydrologic function. Additionally, 

high visitor use at the camp has 

resulted in vegetation trampling 

and riverbank erosion, impacting 

both water quality and riparian 

vegetation. Excess erosion is 

caused by high flows over 

parking areas, around tent cabins 

and down roadways and foot 

trails. 

Focus visitor use and river access 

to the two resilient beach 

locations on the western edge of 

Housekeeping Camp and across 

the footbridge. Fence off current 

eastern river access point located 

on a steep eroded bank, and 

actively restore riverbank with 

brush layering. Where 

infrastructure is removed, 

decompact soils and plant 

riparian species. 

There are currently 266 units at 

Housekeeping Camp that are 

protected by riverbank 

revetment. Many Housekeeping 

Camp units are located in the 2- 

to 10-year floodplain. High visitor 

use and the close proximity of 

these units to the riverbank and 

riparian zone would continue to 

result in denuded riverbanks.

RES-2-063 2 Clark's Bridge to El 

Capitan Bridge: 

large wood 

management

Long-term removal of large wood 

from the river between Clark's 

Bridge to El Cap Bridge has 

reduced channel complexity and 

compromised riparian structure 

and aquatic habitat.

Manage large wood according to 

the ”Yosemite Directive #31: 

Large Wood Management in the 

Merced Wild and Scenic River" 

policy. Trees that fall into the 

river will be retained in the river. 

Large wood may be minimally 

manipulated to protect critical 

infrastructure, to ensure visitor 

safety, and to prevent unnatural 

accumulation of wood due to 

bridges.

Large woody debris (LWD) has 

been removed from the river 

between Clark's Bridge to El Cap

the Big Oak Flat 

Road/El Portal Road 

intersection: river 

access and roadside 

parking

The segment of the El Portal 

Road between Pohono Bridge 

and the intersection of the Big 

Oak Flat Road has a number of 

non-delineated, dirt roadside 

pullouts. There are no designated 

river access points in this reach. 

Visitor use of these informal pullouts along the river has resulted 

in substantial non-historic 

informal trailing, riverbank 

erosion and loss of riparian 

vegetation. Visitor experience and 

resource protection are not 

optimal for accessing the river in 

this area.

pull-outs on El Portal Road. Install 

curbing in 4 pull-outs and along 

El Portal Road. Formalize river 

access in other sensitive areas.

Day-use Parking 

Area: vehicle vs.

and intersection 

performance at 

Northside Drive and

Throughout the peak summer 

season, significant delays in 

outbound traffic flow are 

experienced at the intersection of 

Northside Drive and Village Drive 

due to vehicle-pedestrian 

conflicts and poor intersection 

performance. This is an offset 

four-way intersection connecting 

the exit to Yosemite Village Dayuse Area, Northside Drive, and 

Village Drive. A bike path, shuttle 

stop, and pedestrian crossings 

through this intersection create 

conflicts between vehicular and 

pedestrian traffic. The 

intersection's offset design also 

creates confusion for motorists 

diminishing the intersection 

performance significantly. The 

intersection is not currently 

designed to traffic engineering 

standards for such intersections.

 Significant delays in outbound

RES-4-002 4 Old El Portal: 

parking and 

development in 

valley oaks

Seedling recruitment within the 

rare floodplain community of 

valley oaks in Old El Portal is 

limited by competition from 

invasive species, parking under 

the driplines of trees, associated 

soil compaction, herbivory, and 

existing development. Valley oaks 

are also sensitive to overwatering, 

pruning, grade changes, and 

asphalt covering the root system.

community of valley oaks in Old 

El Portal through implementation 

of mitigation measures related to 

invasive species removal, 

overwatering, tree pruning, and

DETERMINATION OF THE EXTENT NECESSARY FOR

COMMERCIAL SERVICES IN THE WILDERNESS SEGMENTS 

OF THE MERCED WILD AND SCENIC RIVER CORRIDOR

PART 1: INTRODUCTION

The vast majority of Yosemite National Park (95%) was designated as federally protected wilderness by the 

California Wilderness Act of 1984.1 Congress delegated management responsibility for Yosemite Wilderness 

to the National Park Service (NPS). In furtherance of its wilderness management responsibilities, the NPS has 

adopted a trailhead quota system to limit overnight visitation, implemented an extensive educational program 

to teach visitors how to minimize their impacts, promulgated a variety of specific regulations that mandate low 

impact practices, and instituted numerous monitoring programs to assess wilderness character and track 

potential threats to that character. 

The National Park Service has not yet completed an Extent Necessary Determination for commercial 

services for Yosemite’s entire designated wilderness. The need for this type of specialized finding has only 

recently been articulated, stemming from a 2004 decision by the U.S. Court of the Appeals for the Ninth 

Circuit in the case High Sierra Hikers Association v. Blackwell.

2 In the Blackwell decision, the Ninth Circuit 

ruled that wilderness managing agencies must complete a specialized finding of necessity prior to 

authorizing commercial services in wilderness. This finding must be made after considering the extent to 

which commercial services are necessary to achieve the purposes for which the affected wilderness area was 

set aside. Congress directed that Yosemite’s wilderness be set aside for recreational, scenic, scientific, 

educational, conservation, and historical use purposes. This document evaluates the necessity for 

commercial services for designated wilderness portions of the Merced River corridor in light of these 

purposes.

The most appropriate framework for completing an assessment of an Extent Necessary Determination for 

commercial services in wilderness is in the park’s wilderness stewardship plan, where commercial services 

will be addressed comprehensively for Yosemite’s entire wilderness. Yosemite National Park has 

appropriated funding for updating its Wilderness Stewardship Plan, and has begun the initial steps in the 

planning process. The plan, however, will not be ready for public review for several more years. Rather than 

await the development of a new Wilderness Stewardship Plan, the park has elected to analyze commercial 

services in the wilderness portions of the Merced Wild and Scenic River corridor at this time and provide 

the public with an opportunity to comment.

DETERMINATION OF THE EXTENT NECESSARY

PART 2: PURPOSE OF THIS EXTENT NECESSARY DETERMINATION AND 

RELATIONSHIP TO OTHER PLANS

The purpose of this document is to determine limits on commercial services in the wilderness sections of 

the Merced River Corridor in accordance with the requirements of the Wilderness Act and NPS wilderness 

management policies. The limits described in this document apply only to the wilderness segments of the 

Merced River corridor. 

As noted above, the NPS is in the early stages of updating the park’s Wilderness Stewardship Plan. Limits 

adopted in this Extent Necessary Determination will be revisited as part of the planning process for the 

Wilderness Stewardship Plan, which will determine the extent of commercial services necessary throughout 

all of Yosemite’s designated Wilderness. There will be many opportunities for public involvement in the 

development of the Wilderness Stewardship Plan, including the ability to provide additional input on the 

amount of commercial services that should be authorized. 

This Extent Necessary Determination is neither a formal element nor a required component of the Wild and 

Scenic Rivers Act as addressed in the Merced Comprehensive River Management Plan. Under the Wild and 

Scenic Rivers Act, the NPS must adopt specific limits on use within the river corridor to ensure that the 

kinds and amounts of visitor use protect and enhance the river’s outstandingly remarkable values, free 

flowing condition and water quality. The MRP’s capacity determinations, then, represent the maximum 

amount of use that can be allowed without degrading river values. The user capacities that were established 

in the MRP planning process were incorporated into this Extent Necessary Determination. In sections 7 

and 8 below, this document analyzes those capacities in accordance with the requirements of Section 4(d) of 

the Wilderness Act to determine the extent to which any portion of the MRP’s numeric use limits should be 

allocated to commercial service users. This Extent Necessary Determination therefore tiers from the 

capacity determinations in the MRP. 

PART 3: LEGAL FRAMEWORK FOR EVALUATING COMMERCIAL 

SERVICES IN WILDERNESS

A. The Wilderness Act

The Wilderness Act was passed in 1964 to “secure for the American people of present and future 

generations the benefits of an enduring resource of wilderness.”3 Section 4(c) of the Wilderness Act 

explicitly bars “commercial enterprises within designated wilderness areas.”4 An exception to this ban, 

subject to limitations, is provided for commercial services such as guides and outfitters in section 4 (d) 6, which 

states that “commercial services may be performed within the wilderness areas designated by this Act to the 

extent necessary for activities which are proper for realizing the recreational or other wilderness purposes 

of the areas.”5 “Wilderness purposes” are defined in section 4 (b) of the Act as “recreational, scenic, 

scientific, educational, conservation, and historical use.”6

Part 3: Legal Framework for Evaluating Commercial Services in Wilderness

The National Park Service has not issued regulations or formal policy guidance outlining the process for 

authorizing commercial services under Section 4(d) of the Act. However, the U.S. Court of Appeals for the 

Ninth Circuit has issued several decisions interpreting the restrictions on commercial activities found in 

Sections 4(c) and (d) of the Act. These decisions have informed the analysis in this Extent Necessary 

Determination. 

In 2003, the Ninth Circuit, in The Wilderness Society v. U.S. Fish & Wildlife Service, examined the overall 

structure of the Act and found that the Act’s broad mandate to protect wilderness areas was furthered by the 

prohibition provision found in Section 4(c), which among other things, prohibits commercial enterprises in 

wilderness. That prohibition, however, is qualified by the introductory language of Section 4(c) which states, 

“Except as specifically provided for in this [Act] ... there shall be no commercial enterprise” within any 

wilderness area. (Emphasis added.) The exceptions to Section 4(c)’s prohibitions are found in Section 4(d), 

which is entitled “Special provisions.” Of relevance here is the exception allowing for commercial services. The 

commercial services exception is limited in scope. Because of the Act’s structure, in which there is a broad 

prohibition on commercial enterprise in Section 4(c) followed by a list of “special provisions” in Section 4(d), 

the Court concluded that the exceptions found in Section 4(d) are most properly read as a series of limited and 

express exceptions to the general prohibition found in Section 4(c) on commercial enterprises in wilderness.7

In 2004, the Ninth Circuit issued an opinion, High Sierra Hikers Assn. v. Blackwell, interpreting the 

commercial services exception found in Section 4(d)(6) of the Act. The Court examined the specific 

language of Section 4(d)(6), and in particular the language stating that commercial services may only be 

authorized “to the extent necessary,” as well as relationship between Section 4(d)(6) and other provisions of 

the Wilderness Act. According to the Court, the phrase “to the extent necessary” imposed a requirement on 

wilderness managing agencies to make a “specialized” finding of necessity before authorizing commercial 

services in wilderness. In this specialized finding, the agency must “show that the number of permits [or 

other authorizations] granted was no more than was necessary to achieve the goals of the Act.” Although it 

determined that a specialized finding is required, the Court recognized that the Wilderness Act is “framed in 

general terms and does not specify any particular form or content” for the specialized finding. Moreover, 

the Court recognized that wilderness managing agencies are charged with diverse and sometimes conflicting 

mandates under the Act. Agencies are obligated to protect and preserve wilderness areas, but the Act also 

embraces competing directives such as those related to the provision of opportunities for public recreation 

and the discretion to take actions to manage fire and insect risks.8

This Extent Necessary Determination follows the direction provided by these Court opinions. In the 

sections that follow, we identify the types of “activities which are proper for realizing recreational and other 

wilderness purposes” and then determine the numeric amount of commercial services that are necessary to 

realize these purposes, ensuring that the number authorized is no more than necessary so that wilderness 

character will be preserved.

DETERMINATION OF THE EXTENT NECESSARY

B. NPS Wilderness Management Policies

Commercial services must be consistent with the application of the minimum requirement concept and with 

the objectives of the park’s Wilderness Management Plan.9 See Section 9 of this document for the 

application of the minimum requirement concept for commercial allocation.

C. Yosemite Wilderness Management Plan

The Yosemite Wilderness Management Plan states that commercial packers “...may be restricted to 

designated park areas.”10

PART 4: USER CAPACITY IN WILDERNESS 

In the Yosemite Wilderness, wilderness character is preserved in part through the use of the trailhead quota 

system, which limits the amount overnight visitation through the use of a wilderness permit system. In order 

to preserve wilderness character, NPS must ensure that natural resources are protected from damage that 

can result from overuse, and that outstanding opportunities for solitude are preserved. 

The Yosemite trailhead quota system was developed in the 1970s, prior to wilderness designation.11 The 

backcountry area of the park was divided into travel zones. For each zone a capacity was set based on the 

number of acres and miles of trails and desired sociological densities for campsites and trails. The capacities 

were then adjusted to protect ecological resources. For example, capacities were adjusted in zones with 

ecosystems that were rare or vulnerable (such as those with subalpine meadows), or that exhibit fragility or 

limited resilience following impacts (such as those with alpine meadows). Zone capacities have been 

adjusted periodically to reflect new or changed scientific findings regarding ecosystem health and the effect 

of patterns of visitor use on resources. 

In concert with these zone capacities, the NPS has implemented a trailhead quota system. This type of 

system requires beginning a trip at a certain trailhead on a certain day, but otherwise does not generally 

restrict travel plans. Visitor travel patterns were studied to determine the relationship between the various 

trailheads and the travel zones.12 By studying wilderness visitation travel patterns, managers were able to 

determine the percentage of visitors to each zone that are attributable to each trailhead. By limiting the 

number of individuals who may enter the wilderness from a given trailhead on a given day, managers limit 

the number of visitors to each zone such that the wilderness character of the zone, including both the 

physical resources and the outstanding opportunities for solitude, are maintained in accordance with law. 

As part of the Merced River Plan, the NPS reevaluated the wilderness zone capacities within the Merced 

River Corridor in light of the Wild and Scenic Rivers’ Act mandate to protect and enhance Outstandingly 

Remarkable Values and the river’s free-flowing condition. The zone capacities adopted for the river

corridor guided the Extent Necessary Determination process. For six of the eight zones that include the 

Merced River corridor, the zone is much larger than the corridor. This extent necessary determination is for 

the full geographic extent of all eight zones rather than just the corridor. In addition to the use limits set by 

the trailhead quota system, additional limits that relate to wilderness will be in place under the Merced Wild 

and Scenic River Plan. For example, a capacity on grazing nights for pack stock is being established for the 

meadow near the Merced Lake Ranger Station.

PART 5: DEFINITIONS

A. Definition of Proper Activities

Section 4 (d) (6) only allows commercial services which are “proper for realizing the recreational or other 

wilderness purposes of the areas.” Not all activities are proper or allowable in wilderness areas. Section 4(c) 

of the Wilderness Act prohibits public use of motor vehicles, other forms of mechanical transport, 

motorized equipment, and landing of aircraft.13 The 2006 Management Policies provide additional guidance 

on the types of activities that are proper in park wilderness areas. NPS policy states that recreational uses in 

wilderness will be of a nature that:

• Enables the areas to retain their primeval character and influence;

• Protects and preserves natural conditions;

• Leaves the imprint of man’s work substantially unnoticeable;

• Provides outstanding opportunities for solitude or primitive and unconfined types of recreation; 

and

• Preserves wilderness in an unimpaired condition.

14

These restrictions apply equally to commercial and noncommercial public use. In the Yosemite Wilderness, 

proper activities are those traditionally associated with wilderness recreation, including hiking, 

backpacking, stock use, rock climbing, photography, nature study, and others. Improper (and illegal) 

activities include snowmobiling, mountain biking, skateboarding, and others. For a commercial service to be 

considered, it must first be related to an activity that is proper in wilderness. Therefore, the only commercial 

services considered in this document are those related to the types of activities found to be proper in 

Yosemite wilderness.

The Wilderness Act directs that wilderness areas be administered “so as to provide...for the gathering and 

dissemination of information regarding their use and enjoyment as wilderness.”15 The making of films in 

wilderness is considered proper for realizing the educational and scenic purposes.

B. Definition of Commercial Services

Before the National Park Service can determine the types of commercial services that are necessary to further 

wilderness purposes, the agency must first determine which services are commercial in nature and which are 

13 16 USC 1133 (c).

APPENDIX L 

DETERMINATION OF THE EXTENT NECESSARY

not. The Wilderness Act does not define the term “commercial service.” When Congress has failed to include 

definitions of important terms in a statute, agencies may rely on commonly accepted definitions. The word 

“commercial” is commonly defined as (1) “[o]f or relating to commerce,” i.e., “[t]he buying and selling of 

goods, esp. on a large scale: business,” (2) “[e]ngaged in commerce,” (3) “[i]nvolved in work designed or 

planned for the mass market,” or (4) [h]aving profit as a primary aim.”16 The word “service” is commonly 

defined as, “the organized system of apparatus, appliances, employees, etc., for supplying some 

accommodation required by the public” or “the performance of any duties or work for another; helpful or 

professional activity.”17 Activities that are necessary and proper for realizing wilderness purposes will be 

evaluated to determine whether they reflect consistent, commonly understood usage of the terms 

“commercial” and “services.”

In addition, the agency’s determination as to what constitutes a “commercial service” is guided by an analysis 

of the primary purpose and effect of each service. This further layer of analysis, focused on purpose and effect, 

is supported by judicial precedent.18 While some services are conducted for more than one purpose and may 

have more than one effect, the focus of our analysis is on ascertaining the primary reason for the service. 

Incidental or subsidiary purposes and effects do not dictate that a service be categorized as commercial.

For purposes of this document, a commercial service is one that relates to or is connected with 

commerce wherein work is performed for another person or entity, if the primary purpose is the 

experience of wilderness through support provided for a fee or charge and if the primary effect is that 

the wilderness experience is guided and shaped through the use of support services provided for a fee 

or charge. 

The form of the organization providing the service is also not dispositive of whether the organization is 

offering a commercial service, for example whether it is a non-profit or not-for-profit. Rather, the 

definitions above, including an analysis of the activity’s purpose and effect, will guide a determination of 

whether a service is commercial or not.

Commercial services may be authorized under a number of different legal authorities, using a number of 

different instruments. Of relevance to designated wilderness areas within Yosemite National Park are 

concession contracts, commercial use authorizations, and special use permits.

1. Authorization Mechanisms for Commercial Services

a. Concessions Contracts and Commercial Use Authorizations: 

Services authorized under concessions contracts and commercial use authorizations are considered 

commercial services because the entities holding these authorizations are businesses engaged in commerce, 

they provide a service to the public, members of the public who use these services experience Yosemite 

wilderness directly as a result of this commercial support, and employees of the concessioner and CUA 

holder direct and guide the wilderness experience of the trip participants. CUA holders who lead either 

stock or hiking trips (hiking trips include those that focus on fishing, photography, Nordic skiing, and other 

appropriate activities that do not involve stock transport or technical climbing) are considered providers of 

16 Webster’s II New College Dictionary 225 (1995); accord Merriam-Webster’s Collegiate Dictionary 230 (2000). See

Wilderness Society v. U.S. Fish and Wildlife Service, 353 F.3d. 1051, 1061 (9th Cir. 2003)

L-6 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS

 
Part 5: Definitions

commercial services, as is the primary park concessioner, which leads stock, hiking, and climbing trips in 

wilderness.

b. Special Use Permits: 

Special Use Permits are used to authorize a wide range of activities, many of which are not commercial. 

Because Special Use Permits are issued on a case by case basis, it is not possible to evaluate all of the 

different activities that might be requested in a special use permit in advance; however, commercial filming 

permits (one type of Special Use Permit) are discussed below. When a request for another type of Special 

Use Permit in wilderness is received, it will be evaluated in accordance with the criteria above to determine 

whether the activity constitutes a commercial service. If it does, a permit will only be authorized in 

accordance with the procedures set out below in Section 8. 

2. Application of the Purpose and Effect Analysis

For the majority of traditional wilderness outfitting and guide services the determination of commerciality is 

straightforward. The commerciality of some uses is not as clear, however, and those uses are analyzed here.

a. Scientific Research:

Scientific research performed by faculty, postdoctoral fellows, or students enrolled in degree-granting 

programs in accredited colleges and universities or holding appointments with governmental agencies or 

scientific research institutions, even when accompanied by pack stock support, will typically not be 

considered commercial. Research trips using pack stock support would normally not be classified as a 

commercial service trip because the primary purpose and effect of the trip is the enhancement of scientific 

understanding of park resources, not commercial interests. The NPS will review requests for scientific 

research permits that involve the support of commercial outfitters to determine whether the trip is 

commercial. In the event that a research trip is categorized as a commercial service, it will be allowed in 

accordance with the procedures set out below in Section 8.19

b. Commercial Filming and Photography: 

The NPS allows commercial filming and photography in national parks provided that there would not be a 

likelihood of resource damage, an unreasonable disruption of the public’s use and enjoyment of the site, or a 

health or safety risk to the public.20 Filming involves movement or motion of the subject whereas photography 

does not. The NPS Management Policies define “commercial filming” as “filming that involves the digital or 

film recording of a visual image or sound recording by a person, business, or other entity for a market 

audience.” All commercial filming is subject to permitting requirements, and is limited to projects that are 

necessary or proper for providing educational information about wilderness uses, resources or values, or 

necessary for other wilderness purposes. Still photography is only subject to permitting requirements if it takes 

place in areas not open to the public, involves the use of models or props that are not part of the location’s 

existing setting, or requires NPS oversight. Based on the NPS policy cited above, all commercial filming and 

photography will be treated as a commercial service. 

19 Some scientific research could involve a commercial component if it contained an element of “bioprospecting.” Any 

such proposals will be reviewed for legality under the Wilderness Act and commerciality under the guidelines noted 

above.

DETERMINATION OF THE EXTENT NECESSARY

c. Trips by Educational Institutions: 

Each year, the park receives requests for wilderness trips by student groups from accredited educational 

institutions that are conducting classes for course credit. These institutions range from elementary, middle, 

and high schools to colleges and universities. The goal of these trips is to provide environmental education 

to students and to foster self-reliance and other qualities. In some cases, employees of the educational 

institution guide the trip. In others, the school retains the services of an institution with expertise in 

environmental education. NatureBridge, a park partner whose mission is environmental education, leads 

many trips of this type (A small percentage of NatureBridge’s trips are not for academic credit and are 

considered commercial). Trips by accredited academic institutions which give course credit for completion, 

even if accompanied by Yosemite Institute or a similar organization, are not considered commercial services 

for the purposes of this Extent Necessary Determination. The primary purpose and effect of these trips is 

fulfilling academic goals for the students involved. The students’ experience is guided and shaped by the 

institution’s academic goals. Support services from environmental education organizations like 

NatureBridge do not change the essential character of the trip, which is academic, not commercial.

C. Definition of Wilderness Purposes

1. Recreation 

All visitors to the Yosemite Wilderness help to realize the recreational purpose. The recreational purpose is

realized when people are engaged in proper activities in wilderness. Those activities are described in Section 

5.A above. Hiking, backpacking, horseback riding, fishing, climbing, nature study, and mountaineering are 

just a few examples of the many ways that visitors help to realize this purpose. Yosemite National Park does 

not allocate capacity to particular wilderness recreational activities.21

2. Education

While many wilderness visitors are engaged in some type of informal, self-directed education, formal 

education is also necessary to realize the educational purpose. 

Examples of formal education that realize the educational purpose of wilderness include, but are not limited 

to the following:

“How to” education on such topics as:

• Equipment selection

• Navigation

• Wilderness first aid 

• Travel and camping skills

More advanced “skills” training on such topics as:

• Rock climbing

21 This approach is reaffirmed by a recent district court ruling that stated: “...neither fishing nor any other particular 

activity is endorsed by the Wilderness Act, nor is the enhancement of any particular recreational potential a necessary 

duty of wilderness area management.” High Sierra Hikers Assn. v. U.S. Forest Service, 436 F.Supp.2d 1117, 1144 (E.D. 

Cal. 2006).

considered to fulfill the “scenic” purpose described below at Section 5.B.3.

DETERMINATION OF THE EXTENT NECESSARY

3. Scenic

Wilderness possesses a particular type of scenery-natural and untrammeled. The scenic purpose is realized 

when visitors observe the natural landscape of wilderness. It is also realized when people take photographs 

of scenery and share them with others outside of the wilderness. As with the educational purpose, however, 

there is a more formal appreciation of scenery that is enjoyed by photographers and other artists. 

Commercial services provide necessary support for this purpose if they offer photography, painting, or even 

writing workshops that focus on appreciating and interpreting the scenery. Commercial filming, 

videography, audiography, and photography also realize the scenic purpose if they focus on wilderness 

scenery and soundscape. 

4. Conservation 

Conservation means actions that help to maintain the wilderness in a largely natural and untrammeled state, 

with native biodiversity intact and natural processes uninterrupted. 

Examples of activities in wilderness that help to realize the conservation purpose include, but are not limited 

to:

• Ecological restoration projects

• Trail building and maintenance 

• Species preservation activities 

• Eradication or removal of non-native invasive species

Realizing the conservation purpose is primarily a government agency responsibility. Occasionally a visitor 

group conducts a “service trip” that includes conservation work. In Yosemite, however, these groups are 

not able to work independently of NPS control and supervision. They are designated as volunteers, and are 

thus agents of the National Park Service. This purpose is realized by the agency, not by commercial services. 

If the primary purpose of the service trip is to construct, implement or maintain a conservation project, then 

the purpose and effect is non-commercial.

5. Historic

“Historic uses” are defined as those uses which emphasize the wild, untrammeled, and natural character of 

the land in its historic state. Visitors help to realize the historic purpose when they encounter the land as did 

those of earlier historical periods. The historic purpose is realized by maintaining the wilderness character 

of the land, by primitive recreation in the wilderness, by the provision of opportunities for solitude, and by 

enjoying the scenic wonders of the natural and untrammeled landscape. The realization of this purpose is 

consistent with the realization of the conservation and recreational purposes. 

The courts have directly addressed the meaning of “historic uses” as used in the Wilderness Act, and have 

uniformly construed “historic use” to mean use of the primeval or ancient wilderness in its natural state. The 

U.S. Court of Appeals for the 11th Circuit found that “the only reasonable reading of “historical use” in the 

Wilderness Act refers to experiencing the natural, rather than man made, features.”23 This decision was 

followed by the district court in Olympic Park v. Mainella, which held that:

23 Wilderness Watch v. Mainella, 2004, 375 F.3d 1085 (11th Cir. 2004), followed by Olympic Park Associates v. Mainella, 

2005 WL 1871114 (D. Wash. 2005) 

L-10 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS

 
Part 6: Extent Necessary Determination

[t]he Park Service references the historic pattern of shelter construction and recreational use in 

concluding that the “setting, association, and feeling are significant aspects of historic use within 

the park” (AR 416-17), but while this may be true, this type of usage is in the past and a new value 

has been placed on the land by the creation of the Olympic Wilderness....a different “feeling” of 

wilderness is sought to be preserved for future generations to enjoy, a place “where the earth and its 

community of life are untrammeled by man” and which retains “its primitive character and 

influence.”24

Thus, “historic use” refers to preserving the wilderness character of the land so that each visitor may 

encounter it in its historic state, as undeveloped as it was when modern humans first experienced it. No 

commercial services are necessary for the realization of the historical purpose because its realization is 

congruent with the realization of the conservation purpose.

6. Scientific 

The natural and untrammeled qualities of wilderness make an area valuable to science. Realizing the 

scientific purpose means allowing scientific research and monitoring to take place in wilderness. Unlike 

conservation activities, scientific activities fall on a spectrum from administrative to independent: Some are 

conducted by the agency, some are conducted by academics but sponsored or overseen by the agency, and 

some are conducted by independent academics or graduate students. Research conducted by or for the NPS 

is considered administrative, not commercial. On rare occasions an independent researcher might require 

commercial services to pack in supplies. However as discussed above in Section 5, the incidental use of pack 

services to support a research trip typically would not convert a research trip into a commercial service. 

In the Yosemite Wilderness, research is reviewed by an interdisciplinary permit committee and limited 

though a process articulated in An Interagency Framework to Evaluate Proposals for Scientific Activities in 

Wilderness.

25 This framework, including the application of the minimum requirement concept, provides 

methods to quantify the impacts and benefits of research, compare costs and benefits, and prioritize 

research proposals.

PART 6: EXTENT NECESSARY DETERMINATION

This section describes the thresholds and methods used to determine limits on commercial services in the 

wilderness portions of the Merced River corridor. As noted above, no commercial services are needed for 

the realization of the historic, scientific, or conservation purposes. All proposed commercial trips in 

wilderness will be assessed to see which purposes they fulfill (see section on the application process, below).

A. Overnight Use

The wilderness portions of the Merced River corridor are overlaid with eight wilderness management 

zones. Each zone has an established capacity and trailhead limits are enforced. The extent necessary 

determination for overnight trips analyzes use in each zone by month. 

24 Olympic Park Associates v. Mainella, 2005 WL 1871114 (D.Wash. 2005)

Activities in Wilderness, 2009 at wilderness.net/toolboxes.

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS L-11

 
APPENDIX L 

DETERMINATION OF THE EXTENT NECESSARY

1. Recreational Purpose 

Under the Wilderness Act, the NPS can only authorize commercial services in wilderness if they are 

necessary to realize wilderness purposes. Therefore it is important to understand the amount of noncommercial use that is occurring in relation to established capacities. If a wilderness zone is substantially full 

with noncommercial visitors, then commercial visitors are not needed to realize the recreational purpose. 

To determine whether an area is “substantially full,” the following method is used: 

Each zone is accessed by a number of trailheads, each with a daily quota for overnight use (see capacity 

discussion above in Part 4). For each zone, permit records for all trailheads that provide more than 10% of 

the overnight visitors to that zone are tallied (minus permits for commercial groups) and compared to the 

trailhead quotas. The number of days per month that those trailhead quotas are at least 90% full is tallied. 

Those days are considered “full.” 90% was chosen instead of 100% because visitors are frequently turned 

away before 100% of the quota is reached. For example, if only one spot is left, groups of two or greater will 

be turned away. On many days reserved permits are cancelled, or groups with a reservation arrive with a 

smaller group than planned. When this happens late in the day, utilization is slightly less than the quota even 

though many groups may have been turned away.

This analysis is done by month, using a five year average of wilderness permit data from 2005-2009. If a zone 

is “full” more than 66% of the days in a month, that zone is considered substantially full, and will be 

considered a “restricted” zone. Those zones where the trailheads serving the zone are full 33% to 65% of 

the time are “weekend restricted” zones. Typically the full days fall on weekend nights, with Fridays and 

Saturdays the most likely to be substantially full. 

Webster’s Dictionary defines “realized” as “to bring into concrete existence.” It is not necessary that a zone 

be filled to capacity in order for the recreational purpose of that zone to be realized. However, “realization” 

implies a level of “concrete” use beyond the minimum. Many zones are popular destinations with great 

demand for access from both the public and commercial outfitters. A zone threshold of 66% for 

“realization” of the recreational purpose means that all wilderness permits for that zone are issued 4.6 days 

per week throughout the month. This means that every weekend and holiday as well as many weekdays is 

filled to capacity for that zone. Additionally, in many popular zones even those days on which utilization 

falls below 90% it often exceeds 80%. This means that the overall percentage of a quota utilized for a given 

month may be significantly higher than the percentage of “full” days. The level at which a purpose is realized 

necessarily entails an exercise of management judgment. This definition of “realization” balances the 

competing factors of access for commercial recreational groups against the overall preference expressed in 

the Wilderness Act for noncommercial recreational visitation. 

A zone threshold of 33% to 65% for a “weekend restricted” zone means that this zone is filled to capacity 

between 10 and 19 days per month. This means that every weekend and holiday is filled to capacity for that 

zone. Noncommercial public recreational demand is dramatically increased on weekends. The “weekend 

restricted” designation maintains commercial recreational access to desirable areas by permitting it on 

weekdays, when it helps realize the recreational purpose, while maximizing noncommercial recreational 

access on weekends. 

The results of the overnight commercial recreational capacity analysis are as follows. Restricted zones are 

LYV in June, July, and August, and Merced Lake in July and August. Weekend restricted zones are LYV in 

May and September, and Merced Lake in September. 

L-12 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS
Part 6: Extent Necessary Determination

Overnight commercial groups will be allowed to travel through restricted or weekend restricted zones as 

long they spend the night outside of such zones.

2. Educational Purpose 

The educational purpose is considered realized when there are opportunities for both informal and formal 

education taking place in the wilderness. Informal education is self-directed learning available to all 

wilderness visitors. The realization of the “informal” component of the educational purpose can be 

considered as numerically congruent with the realization of the recreational purpose: All those who are 

recreating are in some way engaged in informal education. Directed, formal education is also a proper 

activity in wilderness and also realizes the educational purpose. Formal education presented by a qualified 

instructor can promote a deeper, more comprehensive understanding of wilderness related subjects. An 

allocation of 10% of capacity is necessary to ensure that there is sufficient opportunity for formal education 

and classes, including the making of educational films. Trips that realize the educational purpose also, by 

definition, also realize the recreational purpose and therefore educational trips in excess of 10% of capacity 

would be allowed in non-restricted zones to help realize the recreational purpose.

The percent of capacity allocated to formal education is small for a number of reasons:

• The educational purpose is largely being realized through informal education

• NPS Management Policies directs that “. . . the service will, to the extent practicable, afford visitors 

ample opportunity for inspiration, appreciation, and enjoyment through their own personalized 

experiences-without the formality of program or structure.”26

• Commercial educational use in restricted and weekend-restricted zones will displace non 

commercial use. Under the overall structure of the Wilderness Act, denial of access to non 

commercial visitors in favor of commercial visitors should be minimized.

Classes offered by accredited schools for which students receive academic credit are not considered 

commercial and are not restricted by this allocation (see section 5).

For restricted zones, and weekend restricted zones on weekends, formal education conducted by 

noncommercial entities such as the NPS, and accredited schools, colleges, and universities conducting 

classes for academic credit is also realizing the educational purpose, and will first be subtracted from that 

10% of capacity. The remaining allocation, if any, will be available for commercial formal education in order 

to realize the educational purpose.

3. Scenic Purpose

All visitors are engaging in informal appreciation of wilderness scenery, as are individuals located outside of 

wilderness who are looking in from a road or other developed area. Formal appreciation of wilderness 

scenery, such as art and photography workshops, can foster a more structured understanding of scenery 

and is also necessary to realize a purpose of the Wilderness Act. An allocation of 5 % of capacity is necessary 

to ensure that there is sufficient opportunity for formal appreciation of wilderness scenery, including the 

making of films that focus on wilderness scenery. Trips that realize the Scenic purpose also, by definition, 

also realize the recreational purpose and therefore Scenic trips in excess of 5% of capacity would be allowed 

in non-restricted zones to help realize the recreational purpose. 

26 NPS Management Policies 2006 8.2

Merced Wild and Scenic River Final Comprehensive Management Plan / EIS L-13

 
APPENDIX L 

DETERMINATION OF THE EXTENT NECESSARY

The percent of capacity allocated to formal appreciation of scenery is small for a number of reasons:

• The scenic purpose is largely being realized through informal appreciation, both inside and outside 

of wilderness

• Policy guidance, noted above, that directs that non-formal opportunities be “ample.”

• Commercial scenic use in restricted and weekend-restricted zones will displace non commercial 

use. Under the overall structure of the Wilderness Act, denial of access to non commercial visitors 

in favor of commercial visitors should be minimized.

Art and photography classes offered by accredited schools for course credit are not considered commercial 

and are not restricted by this allocation (see section 5). 

B. Day Use

The only significant day use in the Merced River Corridor is in the Little Yosemite Valley area. Nearly all of 

this day use is on the one mile section of the John Muir Trail from the top of Nevada Fall to where the trail 

leaves the corridor near the designated camping area. An analysis of commercial use from 2005-2009 shows 

that all commercial day use in the corridor was limited to hikes to Half Dome. That use has already been 

limited through an Extent Necessary Determination for the Half Dome Stewardship Plan. That plan limits 

commercial day use to a maximum of 30 people per day for trips that realize the educational purpose and 15 

people per day for trips that realize the scenic purpose. Those limits are appropriate for realizing the 

educational scenic purposes of wilderness in the Merced River corridor while protecting other wilderness 

values.

C. High Sierra Camps

In 1984, when Congress designated the Yosemite Wilderness, it allowed the continuation of the High Sierra 

Camps as a non-conforming use and designated the immediate areas of the camps as potential wilderness 

additions. The only High Sierra Camp in the Merced River corridor is Merced Lake. 

The camps are a commercial operation and offer seasonal, rustic accommodations. Under the preferred 

alternative, the Merced Lake High Sierra Camp will provide 42 guest beds, offer full meal service to guests, 

and sell sundry items to both camp guests and other visitors. It is typically open from early July to early 

September. The National Park Service, in conjunction with the concessioner, conducts commercial 

educational “loop trips” to the High Sierra Camps and provides formal interpretative educational programs 

to both High Sierra Camp guests and backpackers from nearby campgrounds. 

The Merced Lake High Sierra Camp is a substantial commercial presence and affects the wilderness 

experience of visitors in the area, as do the visitors, employees, support personnel, and supply trips going to 

and from the camp. The nature of the camp, with a nonconforming level of development and services, 

means that the Merced Lake zone is highly commercialized compared to those zones that have only more 

traditional, conforming outfitter and guide services. To prevent further commercialization of this area, the 

Merced Lake zone will be managed as “restricted” during July and August when the camp is open, and the 

commercial formal education provided by the NPS-concession loop trips will be subtracted from the 

overnight use allocations for such use, as well as noncommercial educational use. 

L-14 Merced Wild and Scenic River Final Comprehensive Management Plan / EIS
Part 6: Extent Necessary Determination

D. Disabled Access

NPS Management Policies states that the agency must “make available equal opportunities for people with 

disabilities in all programs and activities.”27 For some people who are mobility impaired, commercial stock 

services may provide the only reasonable way to access the wilderness. This Extent Necessary 

Determination only prohibits some types of commercial use in two wilderness management zones (there are 

53 such zones in the entire wilderness; 8 in the Merced River corridor) for a part of the use season. Like 

persons without mobility impairments, mobility impaired visitors may not be able to gain access to their 

preferred destination as part of a commercial trip during the restricted period. However, Yosemite has 

many other areas where visitors can take stock-assisted trips. As such, there are “equal opportunities” for 

mobility impaired individuals to use commercial stock trips to visit the Yosemite Wilderness.

E. Other Commercial Use Limits

In order to honor the clearly expressed legislative intent in the Wilderness Act to limit commercialization of 

wilderness, and the legislative mandate to permit commercial use only to the extent necessary to realize the 

wilderness purposes, the following policies will be implemented:

• In the Yosemite Wilderness, off-trail areas are managed to provide outstanding opportunities to 

enjoy solitude as well as a more pristine natural environment: Group size is limited to eight instead 

of fifteen to provide enhanced opportunities for solitude, and stock use is generally prohibited to 

prevent stock impacts in areas without the protection of properly designed and hardened trails. 

Off-trail areas in the Merced River Corridor zones of the Yosemite Wilderness will be commercialfree areas. No commercial use will be allowed more than 1⁄4 mile from a maintained trail, authorized 

cross country stock route, or public access road (as shown on the latest version of U.S.G.S. 

topographic maps.)

• Overnight commercial trips are limited to two per zone per night. There are three reasons for this 

limit. First, this limit is necessary to protect areas from impacts due to displacement from restricted 

and weekend restricted zones. Such displacement, if not properly managed, could result in 

undesirable physical impacts from grazing or from the creation of new campsites large enough to 

accommodate large commercial groups of 12-15 people, as well as the social impacts of increased 

numbers of large groups. Second, this limit will help to prevent “harmful spikes in use”28 and 

protect the wilderness character of areas to which commercial use may be displaced under the 

operation of this plan.29 If three or more large commercial groups are all displaced to the most 

desirable unrestricted zone, it could create crowding that detracts from the wilderness experience 

of noncommercial visitors sharing a zone with such groups.30 A limit of two commercial trips per 

day in unrestricted zones will prevent this from occurring. Third, this limit will prevent commercial 

groups from dominating any one area and therefore further the intent of the Wilderness Act. 

These limits apply in all zones at all times in addition to the other restrictions noted above.

27 NPS Management Policies 6.4.10 28 See High Sierra Hikers v. Blackwell, 390 F.3d 630 (9th Cir. 2004): High Sierra Hikers Association v. Weingardt, 521 F. 

Supp. 2d 1065 (2007) (holding invalidates the USFS commercial use needs assessment in part because it failed to 

control harmful spikes in use). 29 For a review of the research demonstrating that harms caused by new impacts to areas not previously impacted are 

more extensive than harms to previously impacted areas (the “impact curve”), see Hammitt, W. & Cole, D. (1998) 

Wildland Recreation: Ecology and Management, 2d ed., New York: John Wiley 30 Recent empirical research on visitor experience in the Yosemite Wilderness has documented a visitor preference not

DETERMINATION OF THE EXTENT NECESSARY

PART 7: EXTENT NECESSARY CALCULATIONS FOR THE MERCED RIVER 

CORRIDOR 

The following is an application of the rules in Part 7 to the wilderness portions of the Merced River 

corridor. They apply only to the Merced River corridor, and do not apply to commercial use associated with 

the High Sierra Camps. The allocations are summarized in Table L-1. Some trips may realize all three 

purposes. Such trips will be allocated according to the purpose allocation that is most favorable to the 

commercial service provider.31

A. Limits on all Commercial Use: 

• No camping or travel by commercial groups allowed more than 1⁄4 mile from a maintained trail or 

public access road. No camping allowed in the Mount Lyell zone (The entire zone is off trail.) No 

more than two overnight commercial groups per night per zone.

• All commercial stock trips are limited to a 1:1.5 stock to person ratio. Accordingly, for every 

multiple of 3 persons (including employees), only two pack animals are allowed in addition to 3 

riding stock. See section 9 B.

B. Limits on Commercial Trips that only Realize the Recreational Purpose:

1. Overnight Use

• Restricted zones (LYV, June, July and August only; Merced Lake, July and August only): No 

overnight commercial use allowed. 

• Weekend restricted zones (LYV, May and September only; Merced Lake, September only): 

Commercial use allowed on weekdays; but prohibited on weekends and holidays. (This means no 

overnight stays on Friday and Saturday nights or Sunday night before a Monday holiday. July 4th 

will only be treated as a holiday during years when the federal holiday forms a three day weekend. 

• Commercial trips allowed in the Washburn Lake, Clark Range, South Fork, Johnson Creek, and 

Chilnualna Creek zones all year. Commercial trips allowed in the LYV zone October through April 

and the Merced Lake zones October through June. 

31 Such trips are also favorably evaluated under the minimum requirements analysis described in section 9 below 

because they help to realize multiple purposes at a lower impact than would multiple trips.

C. Limits on Commercial Trips that Realize the Recreational and Educational 

Purposes: 

1. Overnight Use

• Restricted zones (LYV, June, July and August only; Merced Lake, July and August only): Merced

PART 8: THE COMMERCIAL USE APPLICATION PROCESS

A. Procedures Applicable to All Commercial Services in Wilderness

Implementation of this Extent Necessary Determination will be integrated into Yosemite’s CUA and SUP 

application procedures and concession management operations. All entities, including concessioners CUA 

holders, and SUP holders desiring to provide commercial services in the designated wilderness of the 

Merced River corridor shall do the following:

(1) The concessioner, CUA, or Special Use Permit holder must submit a proposed trip itinerary to the 

Yosemite Wilderness Office by May 1 or as soon as is feasible. The itinerary must be received prior 

to any trip entry into the park. The itinerary must provide a schedule of planned trips. For 

overnight trips, the itinerary must include the dates, point of entry and exit, each night’s camping 

location, and the group size (including employees). Day trips must include the date, group size, 

trailhead, and destination. Itineraries received prior to May 1 will be used to assign trips for the 

summer season and may include a second and third choice of trips. 

(2) For educational and scenic trips, the applicant must submit an explanation of the manner in which 

the proposed commercial trip meets the educational or scenic purposes, along with copies of, or 

Internet links to, all advertising and other promotional materials related to that trip and submit 

educational syllabus for trip and documentation showing that employees are trained and qualified 

to provide such education.

Details of the application process are subject to change, but will remain subject to this extent necessary 

determination. 

B. The Minimum Requirement Concept

By policy, the National Park Service must apply the minimum requirement concept to decisions about 

commercial use in wilderness.39 The minimum requirement concept is a two part process that determines 

“if administrative actions, projects, or programs undertaken by the Service or its agent and affecting 

wilderness character, resources, or the visitor experience are necessary, and, if so how to minimize 

impacts.”40

As part of the minimum requirement process, the National Park Service weighs the impacts and benefits to 

wilderness character. Commercial trips that realize more than one purpose accrue more benefit to

nights/month) equals 435 use nights. 5% of 435 equals 22 use nights. Average noncommercial scenic use nights, 

average, 2009-2010 is 0 use nights. 22 minus 0 equals 22 use nights available for commercial scenic use. 39 NPS Management Policies 2006 6.4.4 40 NPS Management Policies 2006 6.3.5

DETERMINATION OF THE EXTENT NECESSARY

wilderness character than those that only realize one purpose but have the same amount of impact. For this 

reason trips that realize a higher number of purposes will receive preference over those realizing a lower 

number of purposes when allocating access.

Part of a minimum requirement decision is determining whether an activity is wilderness dependent. 

Wilderness dependence as used here means if the activity can occur outside of wilderness with little loss of 

value, it should not take place in wilderness. The wilderness dependence criteria will be used during the 

application screening process. Commercial trips whose primary purpose is teaching a subject that is not 

wilderness dependent will be treated as recreational rather than educational. Examples of such topics are 

weight loss and cooking.

Consistent with this concept, when two commercial groups that are realizing the same number of purposes 

are competing for the same date in the same location, the lower impact trip will be given preference. When 

comparing otherwise equivalent commercial stock trips preference will be given to the trip with the lower 

stock-to-client ratio.

In order to minimize the impacts of commercial stock use, all commercial stock trips are limited to a 1:1.5 

stock to person ratio. Accordingly, for every multiple of 3 persons (including employees), only two pack 

animals are allowed in addition to 3 riding stock.

C. Process for Allocating Proposed Trips

In the event that there is more than one entity that desires to provide Commercial Services on the same date 

in the same zone, priority shall be determined by the application of the following steps, in order: 

(1) Each proposed commercial trip shall be awarded one (1) point for each wilderness public purpose 

(i.e., recreational, educational, scenic) that it realizes. Priority shall be granted to proposed trips 

with higher point totals;

(2) Proposed commercial trips that utilize a lower-impact mode of transportation will be given priority 

over those using higher impact modes of transportation; and

(3) In the case of otherwise comparable stock trips, the trip with the lowest stock to client ratio will be 

given priority.

(4) Any remaining conflicting proposed commercial trips after the application of steps (1) through (3) 

above will be resolved through a lottery for proposed commercial trips that will be conducted on 

May 1 of each calendar year. 

All trips proposed after the May 1 lottery will be allocated on a first come first served basis. With respect to 

trips requested on the same date, any conflicts over requested dates and trailheads will be resolved by the 

application of steps (1) through (4) above. 

D. Compliance

Wilderness Rangers routinely check on Commercial Trips in the field to assure compliance with park 

regulations. An assessment of the extent to which a Commercial Service provider has met its objective with 

respect to satisfaction of wilderness purposes will be added to the CUA contact form, for example to 

evaluate the claim that wilderness education is being provided by qualified personnel in addition to 

recreation.

Part 9: The Reassessment Process

Failing to provide promised educational or scenic opportunities may be grounds for limiting a commercial 

service provider’s ability to provide future commercial trips in the Yosemite Wilderness. 

PART 9: THE REASSESSMENT PROCESS

The limits on commercial use imposed by this plan will be recalculated when significant changes in use 

patterns occur. Two current actions may affect this process. The first is research on wilderness travel 

patterns that was completed in 2010. Trailhead quotas will be adjusted based on the results of this study. As 

a result, travel patterns may change in a way that would affect the results of an Extent Necessary 

Determination. In addition, the National Park Service has taken the initial steps of rewriting the Yosemite 

Wilderness Stewardship Plan, which will include an Extent Necessary Determination for the entire 

wilderness. At that time both visitor use patterns and the Extent Necessary methodology will be 

reevaluated.

As the nation’s principal conservation agency, the Department of the Interior has 

responsibility for most of our nationally owned lands and natural resources. This includes 

fostering sound use of our land and water resources; protecting our fish, wildlife, and 

biological diversity; preserving the environmental and cultural values of our national 

parks and historical places; and providing for the enjoyment of life through outdoor 

recreation. The department assesses our energy and mineral resources and works to 

ensure that their development is in the best interests of all people by encouraging 

stewardship and citizen participation in their care. The department also has a major 

responsibility for American Indian reservation communities and for people who live in 

island territories under U.S. administration.
