HISTORIC PROPERTIES 

Historic Buildings, Structures, and Cultural Landscapes 

Comprehensive investigations of historic sites, structures, and cultural landscape resources have been 

undertaken for Yosemite Valley and El Portal. For other areas, information is taken from overview 

documents (e.g., Greene 1987) and specific inventories (e.g., the Wilderness Historic Resource 

Surveys). The types of resources potentially affected by the Merced River Plan include districts, 

buildings, structures, and landscapes listed in the National Register of Historic Places (NRHP, or 

National Register) or designated as National Historic Landmarks. These resource types are described 

below. 

 Districts. A district is a geographically definable area, urban or rural, possessing a significant 

concentration, linkage, or continuity of sites, buildings, structures, or objects united by past 

events or aesthetically by plan or physical development. A district may also comprise individual 

elements separated geographically but linked by association or history (36 CFR 60.3). 

 Buildings. A building is a structure created to shelter any form of human activity, such as a 

house, barn, church, hotel, or similar structure. Building may refer to a historically related 

complex such as a courthouse and jail or a house and barn (36 CFR 60.3). 

 Structures. A structure is a work made up of interdependent and interrelated parts in a 

definite pattern of organization. Constructed by man, it is often an engineering project large in 

scale (examples are historic trails, bridges, road systems, etc.) (36 CFR 60.3). 

 Cultural Landscapes. Cultural landscapes are a geographic area, including both cultural and 

natural resources and the wildlife or domestic animals therein, associated with a historic event, 

activity, or person or exhibiting other cultural or aesthetic values. Cultural landscapes are the 

result of the long interaction between people and the land, and the influence of human beliefs 

and actions over time upon the natural landscape. Shaped through time by historical land use 

and management practices, as well as politics and property laws, levels of technology, and 

economic conditions, cultural landscapes provide a living record of an area’s past, a visual 

chronicle of its history. The dynamic nature of modern human life contributes to the continual 

reshaping of cultural landscapes, making them a good source of information about specific 

times and places but at the same time rendering their long-term preservation a challenge (NPS 

Management Policies 2006). 

National Historic Landmarks. National Historic Landmarks (NHL) are nationally significant 

historic places designated by the Secretary of the Interior because they possess exceptional value or 

quality in illustrating or interpreting the heritage of the United States. Designation as an NHL affords a 

property additional protection as the federal government is tasked with avoiding or minimizing any 

potential adverse effects to the landmark, and monitoring the condition of the property (36 CFR 65) 

National Register of Historic Places Eligibility Criteria. The criteria of the NRHP provide the basis 

under which a structure, site, building, district, or object can be considered significant for listing on the 

National Register. A potential resource needs to meet only one of the four criteria to achieve 

significance. The criteria include resources that (36 CFR 60.4):

and distinguishable entity whose components may lack individual distinction; or 

(D) have yielded or may likely yield information important in prehistory or history. 

Affected Environment 

Regulations and Policies 

Section 106 of National Historic Preservation Act 1966 (as amended). Section 106 of the National 

Historic Preservation Act of 1966 (NHPA) (16 USC 470) directs federal agencies to take into account 

the effects of any undertaking on properties listed in or eligible for listing in the NRHP. The Advisory 

Council on Historic Preservation (ACHP) has developed implementing regulations (36 CFR 800), 

which allow agencies to develop agreements for consideration of these historic properties. 

2008 Programmatic Agreement. The servicewide 2008 programmatic agreement provides coordination 

between the NPS, ACHP, and National Conference of SHPOs for the section 106 compliance process. 

The NHPA, 36 CFR 800, and the 2008 programmatic agreement provide the NPS with a roadmap to 

plan for and carry out undertakings to minimize harm to cultural resources. 

Proposed Merced River Plan Programmatic Agreement. As a part of the current Merced Wild and Scenic 

River Comprehensive Management Plan, the Park is proposing, via consultation with the ACHP, 

SHPO, and traditionally associated American Indian tribes and groups, the development of a 

programmatic agreement regarding treatment of historic resources under the proposed management 

plan (Merced River Plan PA) (36 CFR 800.14). Based on the long term nature of plan implementation, 

a plan specific programmatic agreement will assist in guiding actions in order to avoid or minimize 

adverse effects to historic resources. This document, while not yet finalized, will provide guidance for 

the identification, evaluation, treatment, and mitigation of adverse effects for actions affecting historic 

resources, including potentially eligible historic resources, impacted by the Merced River Plan. A 

process for identifying and implementing appropriate mitigations measures will be developed through 

the programmatic agreement. In the event that the programmatic agreement is not completed prior to 

project initiation, actions will proceed under the guidance of the standard 36 CFR part 800 

consultation process. 

Secretary of the Interior’s Standards for the Treatment of Historic Properties. The Secretary of the 

Interior’s Standards for Treatment of Historic Properties (Standards for Treatment of Historic 

Properties) are prepared under the authority of NHPA Sections 101(f) (g), and (h), and NHPA 

Section 110 and are intended to promote responsible preservation practices that help protect 

irreplaceable cultural resources. The Standards for Treatment of Historic Properties are not intended 

to make decisions about which features of a historic building should be saved and those features that

Historic Buildings, Structures, and Cultural Landscapes 

Merced Wild and Scenic River Comprehensive Management Plan / DEIS 9-1117

may be changed; rather, when a treatment is selected, they provide guidance for consistency in the 

proposed work. 

The four treatment approaches are preservation, rehabilitation, restoration, and reconstruction. 

Preservation places a high premium on the retention of all historic fabric through conservation, 

maintenance, and repair. Rehabilitation emphasizes the retention and repair of historic materials, but 

more latitude is provided for replacement because it is intended to provide a compatible use for a 

property (when the use for which it was originally built is no longer practical or feasible) through 

repair, alterations or additions. Restoration focuses on the retention of materials from the most 

significant time in a property’s history, while permitting the removal of materials from other periods. 

Reconstruction establishes limited opportunities to re-create a nonsurviving site, landscape, building, 

structure, or object in all new materials (Weeks 2001). 

NPS Management Polices 2006. The NPS Management Policies 2006 also provide direction regarding 

the management and preservation of historic properties. In accordance with these policies, the NPS is 

committed to protecting cultural resources against theft, fire, vandalism, overuse, deterioration, 

environmental impacts, and other threats without compromising the integrity of the resources. The 

NPS Management Policies 2006 also provide guidance on procedures for protection and maintenance 

of historic properties under lease, among other instruction. 

Director’s Order 28-Cultural Resources Management Guideline (1998). Director’s Order-28 guides the

NPS to protect and manage cultural resources in its custody through effective research, planning, and 

stewardship and in accordance with the policies and principles contained in the NPS Management 

Policies. It also ensures that the NPS comply with the substantive and procedural requirements 

described in the Secretary of the Interior’s Standards and Guidelines for Archeology and Historic 

Preservation. Additionally, the NPS would comply with the 2008 programmatic agreement with the 

ACHP on Historic Preservation and the National Conference of SHPOs. 

Yosemite National Park General Management Plan (1980). The Yosemite General Management Plan calls 

for a reduction in traffic congestion, removal of nonessential buildings and facilities, restoration of 

large areas of the Valley to their natural conditions, and relocation of visitor and employee 

accommodations away from environmentally sensitive or dangerous areas. 

Cultural Resources Management Plan (1973). The Cultural Resources Management Plan completed for 

the Yosemite General Management Plan was designed to protect the significant cultural resources of 

the park through compliance with all cultural resource legislative, executive, and regulatory 

requirements. The CRMP provides specific policies to guide cultural resources management at 

Yosemite, including consultation, survey and evaluation, preservation/restoration/reuse, and 

documentation. 

Concession Services Plan (1992). The Concession Services Plan, which is a 1992 amendment to the 

Yosemite General Management Plan, guides the management of concession enterprises, such as 

lodging, food, retail, and other commercial services in Yosemite. This plan serves as the basis for 

contracts between the NPS and the park’s primary concessioner.

Scope of the Analysis 

Historical Context 

Arguably, the earliest record of non-indigenous presence in Yosemite was Joseph Rutherford Walker’s 

1833 exploratory party that crossed the Sierra Nevada from east to west, along the divide between the 

Tuolumne River and Merced River drainages. Walker’s party may have been the first non-Indians to see 

Yosemite Valley. Prior to the 1850s, the U. S. military, which had increased its presence in the Central 

Valley, responded to raids by local American Indian tribes and conducted the 1851 relocation of the 

Ahwahneechees, led by Chief Tenaya, to the Fresno River Reservation (Greene 1987). The California 

Gold Rush, the single largest migration in human history, had profound impacts on the land, people and 

resources in the Sierra Nevada foothills. This event triggered massive disruption of native cultures and 

lifeways, brought thousands of people to the lands immediately surrounding Yosemite, and inspired the 

violent conflicts that lead to these military campaigns. In response to the increased military presence, 

some American Indians relocated, though many, including Chief Tenaya, left the camp. 

During the 1850s and 1860s, tourism drove numbers of visitors to Yosemite Valley. Magazines 

depicting the scenery of the Valley drew the attention of the nation, and in 1855 James M. Hutchings 

organized the first tourist excursion to the Valley. Within two years of this trip, entrepreneurs 

constructed hotels to capitalize on what would become a thriving tourist trade. The community of 

Wawona, for example, was founded near the site of the log cabin built by Galen Clark in 1857. Clark, 

originally from New Hampshire, had moved to California during the Gold Rush, and moved to the 

Valley in 1856 as a homesteader. Clark established a 160-acre homestead and 12-foot-by-16-foot 

cabin, which was called “Clark’s Station” or “Clark’s Crossing” (Greene 1987). 

Homestead claims were filed, orchards were planted, and Yosemite Valley became a residential base 

for many families during the 1850s and 1860s. Hutchings became a permanent resident of the Valley in 

1864 and constructed several structures, including a sawmill on Yosemite Creek. By 1870, the 

establishment of visitor hotels in the Valley had created a need for local fresh produce and livestock. 

James Lamon, the Valley’s first non-indigenous homesteader, became one of the largest producers of 

commercial agricultural products in the Valley (Greene 1987). 

In 1864, President Abraham Lincoln and the U.S. Congress set aside the Big Tree Grove (Mariposa 

Grove) and Yosemite Valley as a public park to preserve the monumental scenic qualities of the area. 

The act clearly stated that the Valley and Mariposa Grove were to be managed by the governor of 

California and his eight appointed commissioners, with Frederick Law Olmsted appointed as 

chairman by the governor and elected by the commission (Greene 1987). 

Due to the early conservation movement led by people such as John Muir and Robert Underwood 

Johnson, Congress passed an act establishing Yosemite National Park in 1890. This act brought 

protection to the lands and resources within the watersheds of the Tuolumne River and Merced River 

systems. The park was managed by U.S. Cavalry troops sent from the Presidio in San Francisco. 

Yosemite was the responsibility of the Department of the Interior (DOI), and army units answered to 

both DOI and Army. By 1906, the State of California had relinquished their rights of control over the 

Yosemite Valley and Mariposa Grove grant lands, ceding them to the U.S. government (Greene 1987).

Between 1906 and 1914, Yosemite Valley and the Mariposa Grove were administered by the 

U.S. Army, which established camp at the site of an American Indian village. Major H.C. Benson, 

acting superintendent from 1905 until 1908 under the Department of the Army, stated in his 1907 

annual report that, “[s]ome definite general plan should be devised for the beautifying of the valley and 

making it the most beautiful park in the world. All bridges and buildings constructed in the future 

should conform to a definite plan, suited to existing conditions. All roads should be laid out according 

to a plan fully worked out by a competent landscape gardener, nothing should be done in the way of 

expending money which does not tend to carry out these ideas. All small buildings, practically shacks, 

should be replaced by stone buildings, and all bridges, when replaced, should be either of stone or 

concrete.” Many bridges and roads were, in fact, built by the U.S. Army Corps of Engineers between 

1905 and 1915 (Carr 1998). Bridges such as the Bridalveil Falls bridges in 1913 set the precedent for 

later Rustic design for bridges established in the Yosemite Bridge Historic District. 

In 1916 Congress created the National Park Service with a mandate to conserve the scenery and the 

natural and historic objects and provide opportunities for the enjoyment of future generations. The 

advent of automobile culture in the late 1910s and early 1920s changed the management plan for the 

park. As early as 1919, nearly 75% of visitors to Yosemite entered as auto tourists in their own cars. The 

demographic shift indicated that the era of the national park as a minimally funded, semiprivate resort 

had seen its day. After the All-Year Highway (Highway 140) to Yosemite opened in 1926, the annual 

number of visitors jumped to nearly half a million, up from about 40,000 just 10 years prior. Auto tourists, 

not reliant on concessioners, were part of a much larger and broader public that required additional 

facilities at a scale previously absent from the park (NPS 2006d).Rustic-style architecture was a type of 

design and style of construction used throughout the national parks beginning with the Yosemite 

Administration Building in 1924, and remains in use through the present. The style expressed the 

philosophy that buildings should be in harmony with the landscape and in harmony with each other. 

Oversized stone and logs were used in construction to ensure that the mass of the building appeared to fit 

within the setting. For example, The Ahwahnee hotel, which opened in 1927, is a six-story steel-framed 

building, sheathed in textured concrete and stone veneer to simulate rough wood siding and massive 

stone piers. The Ahwahnee culminated epitomized the tradition of massive, centralized national park 

lodges built by concessioners to cater to wealthy tourists (NPS 2006d). Yosemite Village Historic District 

contains a collection of rustic architecture dating from the 1918 through the 1930s. 

The primary trails originating in the valley are the Mist Trail, Four Mile Trail, Yosemite Falls Trail, 

Pohono Trail, and the Valley Loop Trail. The Valley Loop Trail dates from the 1920s and was originally 

built as a bridle trail, generally aligned along existing circulation routes. Thirteen additional miles were 

added to the Valley Loop Trail in 1928, requiring the construction of 14 bridges. Today, the Valley Loop 

Trail includes the entire remaining bridle trail system in the valley and it is approximately 21 miles long. 

The Great Depression resulted in a decrease of tourists visiting the Valley, but the initiation of 

Franklin D. Roosevelt’s New Deal in the spring of 1933 resulted in an unprecedented era of park 

development and park system expansion. The Public Works Administration and Civilian Conservation 

Corps (CCC) were responsible for completing a tremendous amount of work in the 1930s. Their 

extensive range of projects in the Valley included construction of roads, trails, bridges, fire roads, fire 

buildings, fire lanes, fire trails, comfort stations, campgrounds, and a rock diversion channel at Yosemite 

Creek (Greene 1987).

Visitation to the Valley further decreased during World War II but increased to unprecedented levels 

as soon as the war ended. In 1954, over a million park visitors were recorded. However, in 1955, 

Yosemite experienced the worst flooding ever recorded in the Valley. Facilities that had already been 

damaged in the floods of 1950 were inundated, along with additional roads, trails, bridges, and other 

facilities. In 1956, Park Service Director Conrad L. Wirth announced Mission 66 as a major new 

construction campaign. Intended to improve or replace aging and inadequate national park facilities, 

Mission 66 was implemented to meet the demand for services created by postwar levels of visitation. 

This increased funding and visitation, as well as flood damage repair, came together and resulted in 

major changes to Yosemite Valley. Major Yosemite projects in the Mission 66 program included the 

Tioga Road middle segment and the El Portal Administrative area housing. The Yosemite Valley visitor 

center was completed in 1968. In 1970, much of the Valley’s road network was made into a one-way 

loop. The addition of parking lots along with the new concession and visitor use buildings during the 

Mission 66 period make the public plaza area of the Village one of the most changed areas since 1942 

(NPS 2006d). 

Properties Analyzed for this Plan 

Historic properties that could potentially be affected by the Merced River Plan include various 

National Register-listed historic districts, landscapes, individual historic buildings, structures, trails, 

and other features in each of the river segments that are eligible or potentially eligible for inclusion in 

the NRHP. It should be noted that the majority of post-WWII buildings have not been assessed for 

eligibility and that prior to removal or alteration of these resources, assessments as to their eligibility 

for listing on the National Register would be completed in order to carry out actions with potential 

impact to these areas and appropriate mitigations consistent with the proposed Merced River Plan 

programmatic agreement and consistent with Section 110 of the NHPA. Tables 9-207 through 9-210 

provide detail regarding the historic properties within the APE. 

Historic Period Resources 

Segment 1: Merced River Above Nevada Falls – Historic Properties. Known historic resources 

within Segment 1 consist of the eligible Merced Lake High Sierra Camp Historic District and the 

eligible Merced Lake Ranger Station. Table 9-207 and figure 9-47 describe these resources. 

Segment 2: Yosemite Valley – Historic Properties. Known historic resources within the APE 

associated with Segment 2 include four NRHP- listed districts (Camp Curry Historic District, 

Yosemite Valley Bridges Historic District, Yosemite Valley Historic District, Yosemite Village Historic 

District), including their associated contributing historic buildings and structures; numerous 

structures that have been determined to be eligible for listing on the NRHP as well as those that are 

individually listed; and three National Historic Landmarks (The Ahwahnee, Rangers’ Club, and the 

LeConte Memorial Lodge);. In addition, eight granite-faced, concrete arched, two-lane vehicle bridges 

were constructed along the Valley Loop Road between 1922 and 1933. Six of the bridges (Ahwahnee, 

Clark’s, Pohono, Sugar Pine, Happy Isles, and Stoneman) cross the Merced River, while two others 

(Yosemite Creek and Tenaya Creek) cross creeks. Each bridge is listed in the NRHP as contributing 

features to the Yosemite Valley Historic District, as well as a separate Yosemite Valley Bridges Historic 

District. Table 9-208 describes these resources.

Many historic sites and structures within the Valley have been singled out for their significance and are 

either National Historic Landmarks or are listed in or have been determined eligible for listing in the 

NRHP. National Register-listed historic properties in Yosemite were identified in a 2012 consultation 

letter with SHPO. These resources are described in greater detail in tables 9-207 through 9-210 and 

figure 9-48. 

The geophysical characteristics of Yosemite Valley have shaped patterns of human use since the 

earliest days of American Indian settlement. As a result, the Valley’s cultural landscape is significant for 

its role in the exploration and settlement of the west, as well as for its architecture, art, landscape 

architecture, recreation, and conservation. The historical importance of the Valley landscape derives 

from the fact that countless generations of local tribal groups and, later, millions of park visitors have 

infused the Valley’s natural features with great cultural significance. 

Segments 3 and 4: Merced River Gorge and El Portal – Historic Properties. Known historic 

resources within Segments 3 and 4 include the Merced River Travel Corridor, the Yosemite 

Hydroelectric Power Plant (the Cascades Powerhouse), the Old Coulterville Forestry Department 

Road and Trail, and designated El Portal Historic Structures. Table 9-209 describes these resources 

and figures 9-49 and 9-50. 

The primary element of the Merced Canyon Travel Corridor is El Portal Road, which was originally 

constructed as a wagon road in 1905 and was substantially reconstructed in 1925. The road includes 

hand-laid stone parapet guardwalls and drainage catchment structures. Following consultation with 

the SHPO and the ACHP, many of these features were removed as part of the El Portal Road 

Reconstruction Project that was a direct consequence of damage caused by a catastrophic flood in 

1997. Other properties within the river corridor include rock quarries, historic trash scatters, sections 

of pre-1925 roadbed, historic work campsites, and the Arch Rock Entrance Station complex (eligible 

for the NRHP as an individual property), which consists of a ranger residence/office, entrance kiosk, 

parking lot, and restroom building (Volpe 1997).

Yosemite Valley Historic District (2004001159) 

District Listed National The Valley floor landscape as a whole is nationally significant 

in the themes of outdoor recreation, tourism, and conservation. Since 1864, Yosemite has been an archetype for the preservation of scenic places through their development as public parks. 

District consists of 929 buildings and sites, including Yosemite Valley Chapel, LeConte Memorial Lodge, El Capitan Bridge, Ansel Adams Residence, Yosemite Pioneer Cemetery, and The Ahwahnee, located within specific developed areas including the Yosemite Village, Camp Curry, and The Ahwahnee Additionally, Yosemite Valley Historic District includes resources such as natural systems/features, spatial organization, veg, circulation, land use, vistas, etc. all contribute to the significance of the district 

Yosemite Village Historic District (1978000354) 

District Listed National This historic district, through both sites and structures, 

represents almost the entire range of Yosemite history since 1855, including early homesteading, John Muir’s early residence in the park, the development of the national park, the U.S. Army’s role in park administration, and the evolution of early NPS administration and interpretation of the resources of Yosemite. 

District consists of 44 buildings and sites, including residences, Ansel Adams studio, museum, post office, and park administration building. 

National Historic Landmarks The Ahwahnee Hotel Building Listed National The Ahwahnee, because of its Rustic architectural design and 

unaltered condition, is among the most significant park hotels in the country. The significance of the hotel lies in the preservation of the exterior of the building and its setting, and in the preservation of the interior, with its original decorative features and furnishings. 

Included within the boundaries of the nomination are the meadow directly south of the hotel, the stone gatehouse marking the entrance to the property, the parking lots, and the small pond and walkways at the building's entrance, directly north of the porte-cochere. 

LeConte Memorial Lodge Building Listed Regional, local Originally constructed in 1903, and moved and rebuilt in 1919, 

this lodge was the principal foothold of the influential Sierra Club in the Sierra Nevada Mountains. It is a transitional building in 20th century architecture, with strong European roots in its Tudor Revival design combined, with an interesting use of building materials found in the work of architects of the Bay Area tradition. An outstanding example of the theory that the materials and site should determine the design of the building.

resources within Segments 5, 6, 7, or 8 include the Wawona Hotel and Thomas Hill Studio District 

NHL Wawona, Wawona Covered Bridge, Hodgdon Homestead Cabin, Chris Jorgensen Studio, 

Acting Superintendent’s Headquarters, and the Pioneer Yosemite History Center. Table 9-210 and 

figure 9-51 describe these resources. 

The most significant of the historic structures in Wawona is the Victorian-style Wawona Hotel 

complex. The hotel complex includes seven structures and is significant for its architectural features as 

well as for its historical associations with early California commerce and the landscape painter Thomas 

Hill. The complex includes the Pavilion (former Hill’s Studio), Little White (Manager’s Cottage), Little 

Brown (Moore Cottage), Long White (Clark Cottage), Long Brown (Washburn Cottage), the Wawona 

Hotel, and the annex. The complex was designated a National Historic Landmark on May 28, 1987. 

The Wawona Golf Course, in operation since 1918, is a being evaluated as a contributing resource 

under the current Cultural Landscape Inventory being completed by the NPS Pacific West Regional 

Office staff. 

The Pioneer Yosemite History Center, which was determined eligible for listing as a historic district by 

the California SHPO in 2011, contains many structures relocated from other areas of the park to its 

current location on the bank of the South Fork Merced River. This site consists of 26 contributing 

features, including Wawona Grey Barn/Washburn Barn; Hodgdon homestead/cabin, Yosemite 

Transportation Company office/Wells Fargo office, Wells Fargo utility building, Acting 

Superintendent's Headquarters/Army cabin, Army tack room, Crane Flat ranger cabin/ranger patrol 

cabin, jail/powder house/morgue, Chris Jorgenson Studio/artist cabin, wagon shelter/wagon shed, 

Wawona Covered Bridge, Wawona stables, Chinese laundry/laundry/carriage shop; Pioneer Yosemite 

History Center signs (two); historic circulation system; flagpoles (two); hitching posts (two); retaining

Environmental Consequences Methodology 

Historic districts, buildings, structures, and landscapes are considered eligible for inclusion in the 

NRHP when the properties have significance and retain integrity associated with events that have 

made a significant contribution to the broad patterns of our history (Criterion A); when they are 

associated with the lives of persons significant in our past (Criterion B); when they embody the 

distinctive characteristics of a type, period, or method of construction (Criterion C); or when they 

have contributed or have the potential to contribute information about the past (Criterion D). 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. Adverse effects include those detailed in CFR 800.5 (a)(2)(i-vii), which include 

physical destruction or damage, alterations inconsistent with the Standards for the Treatment of 

Historic Properties (36 CFR part 68), relocation of the property, change in character of use, or neglect 

resulting in deterioration. 

NEPA Methodology 

Analyses of impacts on the historic built-environment for the purposes of the NEPA are based on: 

 Context. The context of the impact considers whether the impact would be local, 

segmentwide, parkwide, or regional. For this analysis, local impacts would be those that occur 

in a specific area within a segment of the river. This analysis further identifies whether there 

are local impacts in multiple segments. Segmentwide impacts would consist of a number of 

local impacts within a single segment, or larger-scale impacts that would affect the segment as 

a whole. Parkwide impacts would extend beyond the river corridor and the study area within 

Yosemite. Regional impacts would be those that extend to the Yosemite gateway region. 

Intensity. The intensity of impact would depend on the nature, location, and design of the 

undertaking, measurable change in character-defining features of a historic property, and the 

number of contributing elements of a historic district that would be affected. Under NEPA 

criteria, intensity of the impact depends on the eligibility of the resource and considers 

whether the impact on eligible or listed historic resources would be negligible, minor, 

moderate, or major, based on the criteria of adverse effect described above. 

- Negligible. Impact is barely perceptible and not measurable; would be expected to 

have no discernible effect on historic resources; confined to small areas or a single 

contributing element of a larger National Register district or historic resource 

- Minor. Impact is perceptible and measurable; remains localized and not expected to 

have an overall effect on historic resources.

- Moderate. Impact results in clearly detectable changes to a character-defining feature 

of a historic resource and could have an appreciable effect on historic resources. 

- Major. Impact results in a substantial and highly noticeable change in characterdefining features; could permanently alter historic resources.

 Duration. The duration of the impact considers whether the impact would occur in the short 

term or the long term. A short-term impact would be temporary in duration, such as shortterm impacts associated with construction or restoration activities. A long-term impact would 

have a permanent effect on historic resources. 

 Type of Impact. The type of impact considers whether the impact would be beneficial or 

adverse to visitor services. Beneficial impacts would stabilize a historic resource to prevent 

future degradation, or appropriate active intervention would be performed to preserve the 

elements of the resource that qualify it for NRHP eligibility. 

For the purposes of NEPA, “historic resources” include resources listed in and eligible for the NRHP. 

Resources that are assessed by park staff as being potentially eligible for listing on the National 

Register, but have not yet been inventoried, would require additional documentation prior to further 

planning, design and/or construction consistent with Sections 106 and 110 of the NHPA. In 

accordance with 36 CFR 800 criteria of effect, historic properties in the Merced River corridor are 

analyzed qualitatively, based on existing knowledge about values and significant elements and 

modifications that could be identified to alter character-defining features (features that qualify 

properties for inclusion in the NRHP). The proposed actions are assessed for the effects they may have 

on properties within the APE. Actions specific to individual alternatives that would affect these 

historic properties are described under each alternative. 

Evaluating Impacts under the National Historic Preservation Act 

Any prehistoric or historic building, structure, object, site, landscape, or district that is included in, or 

is eligible for inclusion in the National Register, is termed a historic property and is managed for 

protection under the NHPA. 

 Non-eligible historic resources. These are resources that fail to meet the criteria of the NRHP 

as described above. 

 Listed historic resources. Listed historic resources are those properties that the Keeper of the 

National Register has officially added to the National Register of Historic Places.

 Eligible historic resources. Eligible historic resources are those which meet the criteria for 

listing on the National Register of Historic Places, and have been determined eligible either in 

concurrence with the SHPO or the Keeper of the National Register of Historic Places.

Types of historic properties include archeological sites, historic built-environment resources, 

archeological and historic districts, cultural landscapes, and traditional cultural properties. These 

resources may also be considered under the Archeological Resources Protection Act, the Native 

American Graves Protection and Repatriation Act, the American Indian Religious Freedom Act, and 

EO 13007 (Indian Sacred Sites). 

Section 106 of the NHPA requires the federal agency to consider the effects of its undertakings on 

historic properties and to provide the ACHP a reasonable opportunity to comment. The agency must 

also identify the appropriate SHPO/Tribal Historic Preservation Officers to consult with during the 

process. It should also plan to involve the public, and identify other potential consulting parties. 
AFFECTED ENVIRONMENT AND ENVIRONMENTAL CONSEQUENCES

9-1142 Merced Wild and Scenic River Comprehensive Management Plan / DEIS

Section 106 also applies to properties not formally determined eligible, but which meet eligibility 

requirements for the National Register and are therefore treated as eligible until a formal 

determination can be made. 

NHPA Determinations of Effect 

Conventional terms used by the NPS to measure the context, duration, intensity, and type of impact as 

part of NEPA analysis are not valid for assessing effects on historic properties under NHPA standards. 

Because the effect on a historic property is measured by the status of the historic property’s eligibility for 

listing in the NRHP, the negligible, minor, moderate, and major degrees do not apply. Either a historic 

property maintains the characteristics making it eligible for listing in the National Register or it does not. 

The ACHP has issued regulations for the implementation of section 106, entitled Protection of Historic 

Properties (36 CFR 800). ACHP regulations discuss the following types of effect: 

No Historic Properties Affected: When there are no historic properties present, or the action 

would have no effect on historic properties, the action is said to have no effect on historic properties. 

No Adverse Effect: Occurs when there would be an effect on a historic property, but the action 

would not alter characteristics that make the property eligible for inclusion in the National 

Register of Historic Places in a way that would diminish the integrity of the property. 

Adverse Effect: Occurs when an action would alter, directly or indirectly, any of the 

characteristics of a historic property that qualify it for inclusion in the National Register of 

Historic Places in a way that would diminish the integrity of the property’s location, design, 

setting, materials, workmanship, feeling, or association. Adverse effects may include reasonably 

foreseeable effects caused by the action that may occur later in time, be farther removed in 

distance, or be cumulative. 

The regulations allow an agency, such as the park, to defer both the identification of historic 

properties (that is, the identification of whether or not a resource is eligible for the NRHP) and the 

effects assessment through the development of a programmatic agreement. The agreement may also 

stipulate additional terms, such as consultation, reporting criteria, monitoring, and dispute resolution. 

Yosemite National Park’s section 106 review process is governed by national and park-specific 

programmatic agreements among the NPS, the ACHP, and the National Council of SHPOs or the 

California SHPO (NPS, ACHP, and NCSHPO 2008; NPS, SHPO, and ACHP 1999). As described 

previously, the Park is also proposing, via consultation with the ACHP, SHPO, and traditionally 

associated American Indian tribes and groups, the creation of a Merced River Plan PA regarding 

treatment of historic resources under the proposed management plan. 

Resolving Adverse Effects on Historic Properties 

Adverse effects on built-environment historic properties (aboveground buildings and structures) under 

section 106 of the NHPA may be resolved with a good-faith effort to consider whether and how to avoid, 

minimize, or mitigate the effect. This may involve modifying the undertaking, imposing certain 

mitigation conditions, or implementing other measures negotiated in consultation with the SHPO, 

ACHP, American Indian tribal governments, and the public.

Merced Wild and Scenic River Comprehensive Management Plan / DEIS 9-1143

As requested by the State Historic Preservation Officer, compliance for the Merced River Plan will be 

in accordance with standard procedures for the protection of historic properties as identified in 36 

CFR Part 800 as well as the 2008 Nationwide programmatic agreement between the NPS, ACHP, 

NCSHPO for compliance with section 106 of the NHPA. The park is committed to completing a planspecific programmatic agreement per 36 CFR 800.14 prior to completion of the Record of Decision for 

the Merced River Plan. This programmatic agreement will be developed in coordination with the 

California State Historic Preservation Office (SHPO) and the Advisory Council for Historic 

Preservation (ACHP) as well as in consultation with all traditionally associated American Indian tribes 

and groups affiliated with the park. The public will have the opportunity to review the draft 

programmatic agreement between the DEIS and FEIS. 

All action would comply with guidance of the proposed Merced River Plan programmatic agreement. 

In the event that the programmatic agreement is not completed prior to project initiation, actions will 

proceed under the guidance of the standard 36 CFR Part 800 consultation regarding consultation with 

SHPO. 

Special Requirements for Protecting National Historic Landmarks 

The ACHP regulations also discuss special requirements for protecting National Historic Landmarks 

at 36 CFR § 800.10. The Wawona Hotel and Thomas Hill Studio District NHL, for example, is a 

National Historic Landmark in Segment 7 of the river corridor that would be subject to this rule. 

National Historic Landmarks are afforded special consideration in planning efforts to minimize harm. 

This statutory requirement stems from Section 110(f) of the NHPA. 

Area of Potential Effect for this Plan 

As defined under the ACHP regulations at 36 CFR 800.16(d), the area of potential effect means the 

geographic area or areas within which an undertaking may directly or indirectly cause alterations in 

the character or use of historic properties. The proposed APE for the Merced River Plan/DEIS is larger 

than the area encompassed by the Merced River corridor to ensure that the effects of all actions 

proposed under the plan are thoroughly considered. More specifically, the APE extends out 1.5 miles 

on each side of the river channel and includes the boundaries of the archeological and historic districts 

that extend outside the boundaries of the 0.25-mile river corridor (Figure 9-52). 

Environmental Consequences of Alternative 1 (No Action) 

All River Segments 

Under Alternative 1 (No Action), all cultural landscape resources, historic buildings, and structures 

would continue to be managed as they are today. Alternative 1 also includes rehabilitation or other 

historic preservation as defined in existing or future plans that address specific structures, such as the 

Ahwahnee Comprehensive Rehabilitation. Impacts would occur only as a result of ongoing park 

operations and programs, such as facilities maintenance and repair. For historic buildings, cultural 

landscapes, and structures, these activities would be subject to the Secretary of the Interior’s Standards 
AFFECTED ENVIRONMENT AND ENVIRONMENTAL CONSEQUENCES

9-1144 Merced Wild and Scenic River Comprehensive Management Plan / DEIS

for the Treatment of Historic Properties. Under Alternative 1 (No Action), impacts on these resources 

would be negligible under NEPA criteria. Alternative 1 would have no adverse effect on Register-listed 

resources under the NHPA. 

Segment 1: Merced River Above Nevada Fall 

Known historic resources in Segment 1 include the Merced Lake High Sierra Camp Historic District 

and the Merced Lake Ranger Station. Other resources may exist in the upper reaches of the Merced 

River drainage, such as structures associated with early stock men. Under Alternative 1 (No Action), 

impacts on these resources would be negligible under NEPA criteria. Alternative 1 is expected to have 

no adverse effect on these National Register-listed historic properties in Segment 1. 

Segment 2: Yosemite Valley 

The Yosemite Valley Historic District is listed on the NRHP in 2006. Several historic sites, structures, 

and districts throughout the Valley were nominated for the NRHP prior to the Yosemite Valley 

Historic District nomination. These properties are significant on their own merits as well as 

contributing to the Yosemite Valley Historic District. Table 9-211 describes potential impacts to these 

resources under the No Action Alternative. 

Under Alternative 1 (No Action), impacts on the majority of resources would be negligible under 

NEPA criteria, although there would be minor, segment-wide, adverse impacts to the Yosemite Valley 

and Yosemite Village Historic Districts. Alternative 1 is expected to have no adverse effect on the 

majority of National Register-listed historic properties in Segment 2 under NHPA criteria. 

Segments 3 and 4: Merced River Gorge and El Portal 

Based on a cultural resources inventory completed in support of the reconstruction of El Portal Road, 

the NPS, in consultation with the SHPO, determined that the Merced Canyon Travel Corridor is a 

significant historic resource and is eligible for listing in the NRHP. A preliminary cultural landscape 

study conducted in El Portal revealed Old El Portal as a potential historic resource within Segment 4, 

although two other reports have not identified the resource eligible as a district. Both of these 

segments include several historic sites and structures considered eligible for listing in the NRHP. 

Under Alternative 1 (No Action), impacts on these resources would be negligible under NEPA criteria. 

Alternative 1 is expected to have no adverse effect on these National Register-listed historic properties 

in Segments 3 and 4 under NHPA Criteria. 

Segments 5, 6, 7, and 8: South Fork Merced River 

Cultural landscape inventories are being conducted for the Wawona area, focusing on Washburn 

Company holdings (including the Wawona Hotel and Thomas Hill Studio District NHL). This resort 

complex once encompassed many other facilities necessary to support such a remote facility. The 

Pioneer Yosemite History Center, on the banks of the South Fork Merced River, contains many 

structures relocated from other areas of the park. Other structures include the Wawona Covered 

Bridge, gray barn, slaughterhouse, and laundry, now used as a wagon repair shop. Wilderness areas

Segment 2 Actions to 

Protect and Enhance River Values 

Yosemite Valley Historic District (2004001159) (Contributing meadows to the Yosemite Valley Historic District include Bridalveil Meadow, El Captain, Slaughterhouse, Sentinel, Leidig, Cook’s, Ahwahnee, Stoneman, and Lamon Meadows) 

The continued encroachment of conifers into contributing meadows within the Yosemite Valley Historic District would have an adverse effect on the setting of these contributors. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is 

nationally significant in the themes of outdoor recreation, tourism, and conservation. A history of intensive use and management, as well as the iconic significance of the meadows as elements of Yosemite scenery, make the Yosemite meadows contributing sites in the historic district (NPS 2006d). The encroachment of conifers into historic meadow areas in the Yosemite Valley Historic District would impact the historic setting of the meadows, as well as the potential loss of the meadows as contributing resources, resulting in a long term, moderate adverse impact under NEPA. The encroachment of conifers into historic meadow areas in the Yosemite Valley Historic District would alter the character of the contributing resources, and would result in an adverse effect to the historic district under NHPA. 

Segment 2 Actions to 

Manage Visitor Use and Facilities 

Yosemite Valley Historic District, Yosemite Village Historic District 

The continued mothballing of the Superintendent’s 

House would result in an 

adverse effect to both the Yosemite Valley and Yosemite Village Historic Districts. 

Yosemite Village has one of the largest and most significant collections of NPS Rustic style buildings in the national park system, with both concessioner and NPS buildings representing a range of rustic types and building materials (Criterion 3). The Superintendent’s House is a 

contributor to the Yosemite Valley Historic District and the Yosemite Village Historic District (Hart, 1978). The Superintendent's Residence and Garage is subject to recurring flooding and subsequent water damage. The building was mothballed following the 1997 floods. The historic interior finishes of the Superintendent’s Residence, especially the distinctive plaster work, are in poor condition. Also, structural issues related to settling of the foundation have resulted in displacement of walls and floors. Visitor use in this area has caused radiating informal trails that impact Cook's Meadow. The continued impacts to the Superintendent’s House have the potential to diminish the 

integrity of the Yosemite Valley and Yosemite Village Historic Districts. This action would result in a long term, minor adverse impact to the Yosemite Valley and Yosemite Village Historic Districts under NEPA. While the Superintendent's Residence and Garage was mothballed following the 1997 floods, mothballing does not prevent deterioration. The continued mothballing of Residence 1 would result in an adverse effect to the Yosemite Valley and Yosemite Village Historic Districts under NHPA.

above Wawona contain historic trails. Potential impacts under Alternative 1 (No Action) would 

include ongoing degradation of resources from visitor and operational use; however, ongoing 

maintenance and rehabilitation would result in negligible impacts on historic resources. Under 

Alternative 1, impacts on these resources would be negligible under NEPA criteria. Alternative 1 

(No Action) would likely have no adverse effect on these National Register-listed historic properties in 

Segments 5, 6, 7, and 8 under NHPA Criteria. 

Summary of Impacts Under No Action Alternative 

Identified historic resources that could be adversely affected by the No Action Alternative include the 

Yosemite Valley Historic District and the Superintendent’s House. These effects include the alteration of 

character-defining features of these National Register-listed resources through neglect. 

Cumulative Impacts from Alternative 1 (No-Action) 

Past Actions 

Past actions have resulted in a range of beneficial and adverse impacts. Beneficial impacts of past 

actions include extensive actions to preserve and maintain historic resources, including the Camp 

Curry Historic District (Curry Village Registration Building, Guest Lounge and Amphitheater 

Rehabilitation), as well as restoration of meadows associated with the Yosemite Valley Historic 

District (Cook's Meadow). Adverse effects include the removal of the NR eligible Cascades area 

houses. 

Present Actions 

Present actions contribute to a mixture of beneficial and adverse impacts. These impacts include 

efforts to restore, preserve, and protect the historic integrity and character-defining features of The 

Ahwahnee NHL while completing long-term rehabilitation of the building and associated features, 

construction of the Wawona fire station, Camp 4 relocating eight campsites, and the Ahwahnee Hotel 

Porte Cochère Access Walkways and Fence project. Additionally, the park has established the 

Yosemite Valley Rockfall Hazard Zone in Curry Village, which has resulted in the loss of historic 

structures. These structures are being documented under a separate MOA. 

Future Actions 

Impacts from future actions would be similar to those discussed for past and present actions as a mix 

of beneficial and adverse impacts to historic resources. The Curry Village Rehabilitation of Historic 

Cabins with Bath Structures, seismic upgrade to the Ahwahnee Dormitory, and efforts to stabilize the 

floor of the Ahwahnee Hotel, all consist of potential future actions with the potential to affect historic 

resources within the park.

Overall Cumulative Impact 

There would be no change in the treatment and management of historic buildings, structures, and 

cultural landscape resources as a result of Alternative 1 (No Action). The results of the neglect in 

Segment 2 would contribute towards a moderate adverse cumulative effect.

Abandoned infrastructure 

Throughout the corridor, abandoned underground infrastructure that alters hydrology, including remnants of former sewer treatment facilities, sewer and water line, and manholes, will be removed and the area restored to natural conditions. This may affect historic resources. 

Throughout all segments of the Merced Wild and Scenic River corridor, removing abandoned infrastructure has the potential to affect historic resources. These resources have not been previously evaluated for their historic significance, and the loss or demolition of historical resources would be a long term, local, moderate adverse impact, depending on whether the resources are found to be contributors to a historic district or significant in their own right. Park actions to remove abandoned infrastructure throughout the river corridor would be completed subject to the proposed Merced River Plan programmatic agreement (or standard 36 CFR Part 800 consultation) when site-level information is available. Following the determination of site level information, impacts to these properties will be determined per NEPA and NHPA.

The Ahwahnee Hotel (1977000149: NHL) ; Yosemite Valley Historic District (2004001159) 

Restoring the impacted portion of Ahwahnee Meadow to natural meadow conditions, through removal of tennis courts, irrigation, ditches, and restoration of topography would result in the removal of the tennis courts which are a contributing structure to the Ahwahnee Hotel. 

The Ahwahnee, because of its architectural design and pristine condition, is among the most significant park hotels in the country. Its rustic style was designed to reflect its environment, and its significance lies with the preservation of the building and its setting. The Tennis Courts are a contributor to the National Register Ahwahnee Hotel and the Yosemite Valley Historic District, but are located outside the boundary of the National Historic Landmark. The Ahwahnee Meadow is a contributor to the Yosemite Valley Historic District, the National Register listed Ahwahnee Hotel, and the National Historic Landmark Ahwahnee Hotel (Hart 1977; NPS 2006d; Harrison, 1977). NEPA: The removal of the tennis courts, a contributing resource to the Yosemite Valley Historic District and Ahwahnee Hotel, would result in to the alteration of the Ahwahnee Hotel and the Yosemite Valley Historic District. The tennis courts and Ahwahnee meadow are parts of the historic setting and landscape of the Ahwahnee Hotel and contribute to its aesthetic and significance. The removal of the tennis courts would, however, result in a beneficial impact through the restoration of an earlier configuration of the historic Ahwahnee Meadow. The action would be taken consistent with mitigation measure HIST-2 and guidance to be established through development of a programmatic agreement for the Merced River Plan or the standard 36 CFR Part 800 consultation. The proposed removal of the tennis courts would result in a long term, local, moderate adverse effect to the NR Ahwahnee Hotel and the Yosemite Valley Historic District under NEPA. The restoration of the Ahwahnee Meadow would result in a long term, local, beneficial impact to the NR Ahwahnee Hotel and the Yosemite Valley Historic District under NEPA. NHPA: The removal of the tennis courts, a contributing resource to the Yosemite Valley Historic District and Ahwahnee Hotel, would alter both the Yosemite Valley Historic District and NR Ahwahnee Hotel. As described above, the action would be taken consistent with mitigation measure HIST-2 and guidance to be established through development of a programmatic agreement for the Merced River Plan or the standard 36 CFR Part 800 consultation.

Restoration efforts for meadows contributing to Yosemite Valley Historic District (Cook's, Sentinel, Ahwahnee, Stoneman) would result in no adverse effects to the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. The Cook's, Sentinel, Ahwahnee, and Stoneman Meadows are contributing sites to the Yosemite Valley Historic District as characteristic landscape features in the Valley (NPS 2006d). NEPA: The restoration of the meadows to their historic setting would result in a long term, segment-wide, beneficial impact to the Yosemite Valley Historic District under NEPA.

Biological Resource Actions. Biological resource actions to protect and enhance river values in 

Segment 2 under Alternatives 2-6 would result in minor or moderate, local, long term adverse impacts 

on the listed Yosemite Valley Historic District and Ahwahnee Hotel, as both an individual resource 

and a contributor to the Yosemite Valley Historic District, under NEPA, and an adverse effect to the 

Yosemite Valley Historic District and NR Ahwahnee Hotel under NHPA.

Scenic Resource Actions. Scenic resource actions to protect and enhance river values in Segment 2 

under Alternatives 2-6 would result in long term, segment-wide, beneficial effect to the Yosemite 

Valley Historic District through restoration of contributing meadows, and no adverse effect to the 

Yosemite Valley Historic District under NHPA. 

Impacts of Actions to Manage User Capacities, Land Use, and Facilities 

Table 9-214 describes impacts of actions intended to protect and enhance river values in Segment 2 

under Alternatives 2-6. 

Yosemite Village and Housekeeping Camp. Actions in the Yosemite Village area include the 

removal of the Ahwahnee tennis courts and pool and redesign and formalization of parking at the 

Ahwahnee Hotel, redesign of the parking lot and re-routing Northside Drive at Yosemite Village DayUse Parking area, removal of the Valley Concessioner Garage Building and 4 garages north of Curry 

Garage, and repurposing of the Yosemite Valley Group Utility Building (Fort Yosemite). As described 

in table 9-214 below, these actions, other than the Ahwahnee Parking lot redesign, would have a minor 

to moderate, local, long term adverse impact to the listed Yosemite Valley Historic District under 

NEPA, and an adverse effect to the Yosemite Valley Historic District, the Yosemite Village Historic 

District, and the Ahwahnee Hotel under NHPA. The redesign of the Ahwahnee parking lot would 

have no adverse impact to the Yosemite Valley Historic District or Ahwahnee Hotel under NEPA, and 

no adverse effect to the Yosemite Valley Historic District or Ahwahnee Hotel under NHPA. 

Yosemite Lodge and Camp 4. Actions to manage visitor use and facilities in the Yosemite Lodge and 

Camp 4 areas would include the removal of facilities from the Yosemite Lodge area and construction 

of a new bus stop, parking area, and campsites near Camp 4. As described in table 9-214 below, 

Yosemite Lodge was identified as being a non-contributing site within the Yosemite Valley Historic 

District. However, it has not been evaluated for its post-WWII significance under the 50-year rule for 

the inventorying of historic properties for the National Register, and a determination of effect under 

both NEPA and NHPA would occur after a determination of eligibility is completed and concurred upon 

by SHPO during future site planning. Impacts to the Yosemite Valley Historic District through the 

construction of new facilities within the district near Camp 4 would result in a minor, local, long term 

adverse impact on the listed Yosemite Valley Historic District under NEPA, and no adverse effect 

under NHPA.

Retaining the existing facilities and services, including bar and food service, dining room, gift shop, and sweet shop would not affect the Ahwahnee Hotel. Removal of the noncontributing pool would not affect the Ahwahnee Hotel. The tennis courts are considered a contributing structure to the Ahwahnee Hotel, and their removal would affect this historic resource. 

The Ahwahnee, because of its architectural design and pristine condition, is among the most significant park hotels in the country. Its rustic style was designed to reflect its environment, and its significance lies with the preservation of the building and its setting. The pool is a non-contributor to the Yosemite Valley Historic District, the National Register listed Ahwahnee Hotel, and the National Historic Landmark Ahwahnee Hotel (Harrison, 1977; NPS 2006d). NEPA: The retention of existing facilities and removal of the pool would result in no adverse impact to either the NR Ahwahnee Hotel or Yosemite Valley Historic District. The impact of removal of the tennis courts is discussed above in table 9-213. The pool is a non-contributing resource, and its removal would have no effect on the Ahwahnee Hotel or Yosemite Valley Historic District. As described above, the removal of the tennis courts would result in a long term, local, moderate adverse impact to the NR Ahwahnee Hotel and a long term, local, minor adverse impact to the Yosemite Valley Historic District under NEPA. NHPA: The retention of existing facilities and the removal of the pool would not alter historic properties. The pool is a non-contributing resource to the Ahwahnee Hotel and Yosemite Valley Historic District, and the continued use of existing facilities would not diminish the integrity of the Ahwahnee Hotel or Yosemite Valley Historic District. The adverse effect of the removal of the tennis courts is described under actions to restore the Ahwahnee Meadow in table 9-213. As described in table 9-213, the removal of the tennis courts would have an adverse effect on the Yosemite Valley Historic District and NR Ahwahnee Hotel through removal of an identified contributing resource.

The relocation of parking to the north of the road and rerouting Northside Drive south of the parking at Yosemite Village Day-Use Parking area would affect historic circulation patterns in the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is 

nationally significant in the themes of outdoor recreation, tourism, and conservation. Northside and Southside drives create a framework for circulation around the valley, on either side of the Merced River, and are contributing structures to the Yosemite Valley Historic District. The historic circulation of Yosemite Village is predominantly centered on Village Drive between Northside Drive and Village bike path (NPS 2006d). Northside Drive is not a contributor to the Yosemite Village Historic District (Donahoe 1994).

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. Many recreational trends, including sightseeing, camping, auto camping, mountaineering, winter sports, and others began or were significantly advanced at Yosemite (Criterion A). Camp 4 is a historically significant site for its association with the growth and development of rock climbing as a recreational activity within the valley. During its period of significance, Camp 4 earned national and international acclaim as the center of modern rock climbing.

The construction of 12 infill housing units in vacant lots in old El Portal to facilitate removal of temporary housing in Yosemite Valley may impact the historic setting of the area. 

El Portal is a small community comprised of 1200 acres of land on both the north and south sides of the Merced River and Highway 140. Old El Portal contains several listed and eligible historic resources in the vicinity of the proposed infill (El Portal Chapel, Track Bus No. 19, Bagby Stationhouse, Hetch Hetchy Railroad Engine No. 6, and the Yosemite Valley Railroad Caboose No. 15). Old El Portal has been proposed as a historic district and would be significant under Criterion A due to its role in settlement, industry, and tourism in the Yosemite Region, from 1907-1951. Old El Portal historic district was recommended eligible under Criterion C because of its eclectic assemblage of landscape characteristics, including buildings, structures, land use, spatial organization, cluster arrangements, and circulation (NewFields International, 2005).Additionally, some historic resources in El Portal are considered potentially eligible by the Park, including El Portal Hotel and Motor Inn Historic District, Foresta Road, Rancheria Mission 66 Historic District, and Standard Oil office and bulk fuel storage tanks (NPS 2011r). The construction of new housing in old El Portal has the potential to alter the historic setting of the area. A historic resource study identifying potentially eligible properties in the vicinity of El Portal has been completed by park staff (NPS 2011r). This study provides the park with enough research/information to identify potentially eligible resources that will need further Section 110 inventory/analysis to determine eligibility. A determination of effect under NEPA would occur after a determination of eligibility is completed and concurred upon by SHPO during future site planning.

The trailer park was built during the Mission 66 era as part of the development intended for transient structures but lacks any distinct qualities to warrant inclusion on the National Register by itself (NPS 2011r). The removal of private residences in Abbieville and Trailer Village would not alter historic resources in the area. These residences were determined unlikely for listing in the National Register, and their removal would result in a no adverse impact under NEPA.

Historic Buildings in Wawona 

In Wawona Town center, the park plans to construct a 4,500 square foot building and grounds maintenance facility, a 6,800 square foot combined structural and wild land fire station, and a 4,000 square foot roads maintenance facility, and rehabilitate the existing California Conservation Corp (CCC) structures for potential re-use. The construction of new facilities may impact the historic setting of the area, and the reuse of the CCC structures may impact their integrity. 

The community of Wawona possesses several historic resources (Hogdon Homestead Cabin, Acting Superintendent's Headquarters, Chris Jorgensen Studio, and Wawona Covered Bridge), all located over .25 miles from the proposed construction site. The CCC structures have not been previously evaluated as a National Register-eligible resources. The construction of new maintenance facilities in Wawona has the potential to alter the historic setting of the area. The installation new facilities and would comply with NPS cultural resource management guidelines and stipulations of the Merced River Plan programmatic agreement or standard 36 CFR Part 800 consultation. Any new facilities design would be compatible with the distinctive character of the landscape and surrounding buildings. These existing and proposed guidelines would protect historic resources by requiring new facilities to be compatible to the maximum extent possible with the historic materials, features, size, scale, proportion, and massing of existing historic properties. New construction that follows these guidelines would minimize adverse impacts on historic resources under NEPA. The CCC structures have not been evaluated for NR eligibility. The park will complete a Determination of Eligibility prior to implementing the selected action. This action would be completed in compliance with the proposed Merced River Plan programmatic agreement. A determination of effect under both NEPA and NHPA would be required to inform the planning/design process after a Determination of Eligibility is completed and concurred upon by the SHPO.

Merced Lake High Sierra Camp Historic District 

The closure of the Merced Lake High Sierra Camp and conversion of the area to designated wilderness. This would result in the loss of the Merced Lake High Sierra Camp. 

The Merced Lake High Sierra Camp is considered significant in recreation and education as one of seven high country camps whose origin dates back to the earliest days of the National Park Service. The Yosemite camp system initially began in 1916 as an effort to attract people into the park’s high country. Through the use of organized parties guided by a Yosemite naturalist, the Park Service established a unique pattern of interpretive service in the high country of one of the most populous national parks, which helped acquaint the American public with the conservation objectives of the agency in all natural areas of the system (Criterion A) (Kirk, 2004). NEPA: The alteration or removal of historic period buildings and structures in the Merced Lake High Sierra Camp area would affect the Merced Lake High Sierra Camp Historic District. The Merced Lake High Sierra Camp Historic District is one of the few National Register-eligible resources in Segment 1. The demolition of an eligible historic resource represents a substantial and highly noticeable change in character-defining features and the permanent alteration of the historic setting and character of the segment. While the action would be completed consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation), the proposed action would result in a major, long term, local adverse impact on the district under NEPA through the removal and delisting the Merced Lake High Sierra Camp Historic District from the National Register NHPA: The alteration or removal of historic period buildings and structures in the Merced Lake High Sierra Camp area would affect the Merced Lake High Sierra Camp Historic District.

Removal of historic Ahwahnee Row and Tecoya Housing buildings would result in loss of 21 contributing resources to the Yosemite Valley Historic District and Yosemite Village Historic District 

Yosemite Village has one of the largest and most significant collections of NPS Rustic style buildings in the national park system, with both concessioner and NPS buildings representing a range of rustic types and building materials (Criterion 3). Structures in Lower Tecoya include dormitories, apartments and associated laundry rooms, the Ahwahnee Row Houses, small cottages, cabins, and curvilinear roads connects the housing units. The Ahwahnee Row Houses are a group of one-and twostory residences built in the 1920s on the east side of Lower Tecoya, and form a boundary between a densely developed and coniferous Lower Tecoya area and the open Ahwahnee meadow. To the west of the row houses are four three-story wood dormitory buildings and an adjacent kitchen facility. Half of the dormitories in Lower Tecoya were constructed in the late 1920s and significantly altered in the 1930s, while the other half were constructed in the 1930s and remain unchanged. NEPA: The Tecoya concessioner housing area and Ahwahnee Row houses are contributors to both the National Register-listed Yosemite Valley and Yosemite Village Historic Districts. These buildings reflect the rustic architecture characteristic of Yosemite Village, and their loss would result in an adverse impact on this historic resource. These buildings constitute 21 of the 302 contributing buildings within the Yosemite Valley Historic district (with 929 total contributing resources) and 68 contributing buildings to the Yosemite Village Historic District. While the action would be taken consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan (or 36 CFR 800 consultation), the proposed action would result in a moderate, long term, local, adverse impact to both the Yosemite Valley Historic District and the Yosemite Village Historic District under NEPA. NHPA: The Tecoya concessioner housing area and Ahwahnee Row houses are contributors of the National Register-listed Yosemite Valley Historic District, and their removal or demolition would result in an adverse effect on

The restoration of Stoneman Meadow including the re-alignment of Southside Drive would affect historic circulation patterns in the Curry Village Area of the Yosemite Valley Historic District. This action would, however, improve Stoneman Meadow, another contributor to the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is 

nationally significant in the themes of outdoor recreation, tourism, and conservation. Many recreational trends, including sightseeing, camping, auto camping, mountaineering, winter sports, and others began or were significantly advanced at Yosemite (Criterion A). The cultural landscape of Yosemite Valley features nationally significant examples of architecture. Camp Curry is a rare example of a surviving tent cabin complex of the type that was once common in many parks (Criterion C). The historic circulation of Camp Curry is predominantly pedestrian, with vehicular approaches from the west (Old Village) and northwest (Stoneman Bridge). Today vehicular access is limited mainly to the northwestern approach, and the western approach has been converted to parking and foot trail. Since the original entry was oriented to this entrance, the historic gateway has become somewhat obsolete, at least in the current circulation configuration. Stoneman Meadow is a contributing site to the Yosemite Valley Historic District as a characteristic landscape feature in the Valley, as is Southside Drive (NPS 2006d). Southside Drive is not considered a contributor to the Camp Curry Historic District (Hart, 1979). Boys town is not included in the Camp Curry Historic District nomination. NEPA: The realignment of Southside Drive through Boys Town would affect the Yosemite Valley Historic District through alteration of historic circulation patterns in Curry Village and in the Valley. The action will not, however, result in an adverse effect to the historic approach to the Curry Village area, which is the focus of remaining historic vehicular circulation. The road realignment will include a small segment of the entire length of Southside Drive, in an area not out of character with its existing route. Additionally, the restoration of Stoneman Meadow to a more historic setting would have a beneficial effect on the Yosemite Valley Historic District. Finally, the action would be taken consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan or standard 36 CFR Part 800 consultation. The proposed action will have a moderate, local, long term adverse impact on the listed Yosemite Valley Historic District under NEPA.

Rerouting the Valley Loop Trail through Slaughterhouse Meadow has the potential to affect both these contributors to the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. Valley Loop Trail is one of the primary trails originating in the valley. The Valley Loop Trail dates from the 1920s and was originally built as a bridle trail, generally aligned along existing circulation routes. Thirteen additional miles were added to the Valley Loop Trail in 1928, requiring the construction of 14 bridges. Today, the Valley Loop Trail includes the entire remaining bridle trail system in the valley and it is approximately 21 miles long (Criterion A). The Slaughterhouse Meadow is a contributing site to the Yosemite Valley Historic District as a characteristic landscape feature in the Valley (NPS 2006d). NEPA: Both the Valley Loop Trail and Slaughterhouse Meadow are contributors to the National Register-listed Yosemite Valley Historic District. Rerouting the Valley Loop Trail could alter both of these resources. Any sections of Valley Loop Trail that would be rerouted would require additional analysis prior to construction or demolition. The action would comply with guidance to be established through development of a Programmatic Agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation). A determination of effect under both NEPA would occur after a determination of eligibility is completed and concurred upon by SHPO during future site planning.

Removal of Stoneman Bridge, redesign of Sentinel intersection, removal of the Ahwahnee and Sugar Pine Bridges, and restoration to natural conditions would remove contributing structures to the Yosemite Valley Bridges and Yosemite Valley Historic Districts. 

Bridges have been a major component of the cultural landscape of the Yosemite Valley from the first years of non-indigenous settlement. The Yosemite Valley Bridges Historic District consists of 8 granite-faced, concrete arch road bridges on the Valley floor, constructed between 1921 and 1933. The Valley bridges are unique for their architectural design and aesthetic considerations, representing an effort to build structures in the national parks which are simple and uniform in design to blend in with the environment (Criterion C) (Wilson, 1977). This bridge is also a contributor to the Yosemite Valley Historic District. NEPA: The demolition and removal of Stoneman, Ahwahnee, and Sugar Pine Bridges would affect the Yosemite Valley Historic District and the Yosemite Valley Bridges Historic District. The loss of the bridges would result in the loss of nearly half of the contributing resources in the National Register-listed Yosemite Valley Bridges Historic District. This would also result in the loss of several of the major Merced River crossings affecting the integrity of the historic circulation patterns in the Yosemite Valley Historic District. The action would be implemented with either the proposed Merced River Plan programmatic agreement or standard 36 CFR Part 800 consultation.

The re-design of the Curry Orchard Day Use Parking area and extension of the boardwalk through to Curry Village would result in the removal of historic trees and alteration of a contributor to the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. Many recreational trends, including sightseeing, camping, auto camping, mountaineering, winter sports, and others began or were significantly advanced at Yosemite (Criterion A). The cultural landscape of Yosemite Valley features nationally significant examples of architecture. Camp Curry is a rare example of a surviving tent cabin complex of the type that was once common in many parks (Criterion C). In 1927, the Park addressed a growing problem with parking by converting a nearby apple orchard into a unique parking area for Curry Village. Curry Orchard Day Use Parking area is a contributing site to the Yosemite Valley Historic District, but not the Camp Curry Historic District (NPS 2006d; Hart, 1979).NEPA: Efforts to redesign parking within the Curry Orchard parking lot 

would affect a contributing site to the Yosemite Valley Historic District. All trees will be removed from the parking lot. This action would be completed consistent with management practices outlined in the Orchard Management Guidelines and guidance to be established through development of a programmatic agreement for the Merced River Plan (or 

standard 36 CFR Part 800 consultation). The proposed action would result in a long term, local, moderate adverse impact to the Yosemite Valley Historic District under NEPA. NHPA: Efforts to redesign parking within the Curry Orchard parking lot would alter a contributing resource to the Yosemite Valley Historic District. All trees will be removed from the parking lot. This action would be completed consistent with management practices outlined in the Orchard Management Guidelines and guidance to be established through development of a programmatic agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation).

Ecologically restoring the Curry Village Stables area and removal of associated housing would result in removal of the following historic buildings and structures: Concessioner Stables Office, Horse Stable, Mule Barn, Linen Building, Tack Building, Harness Shop, Blacksmith Shop, Comfort Station, Pony Tack Shed #1 and #2, Employee Residence, Employee Cabins (5), Corral, Feeders, and Fence. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. In 1927, the massive stable complex known as Kenneyville was removed to make way for the Ahwahnee Hotel, and a new, smaller stable complex was built to replace it. Now located farther east near the Lamon Orchard, today Kenneyville stables (or Concessioner stables) includes a mule barn, horse stable, five associated support buildings, six employee housing units and a comfort station. With the corrals and fencing through the complex, the cluster remains with good integrity (NPS 2006d). NEPA: The removal of the concessioner stables and associated buildings would affect the Yosemite Valley Historic District through the removal of 16 contributing buildings out of 302 contributing buildings, and 3 contributing sites out of 611 contributing sites, within the district (with 929 total contributing resources). The concessioner stables are the only contributing historic stables within the Yosemite Valley Historic District. The loss of these buildings would result in a clearly detectable change Yosemite Valley Historic District. This action would comply with the guidance to be established through development of a Programmatic Agreement for the Merced River Plan or standard 36 CFR Part 800 consultation.

El Portal is a small community comprised of 1200 acres of land on both the north and south sides of the Merced River and Highway 140. In 1961 the National Park Service began building housing in Rancheria Flat, west of El Portal as part of the Mission 66 initiative in the National Park Service. The Rancheria Mission 66 area has been recommended as a historic district as part of a historic resource study identifying potentially eligible properties in El Portal, but has not yet received SHPO concurrence (NPS 2011r). The construction of new housing in the Rancheria area of El Portal has the potential to alter the historic setting of the area and any potential historic resources not currently eligible or listed by the Park. A historic resource study identifying potentially eligible properties in the vicinity of El Portal has been completed by park staff (NPS 2011r). This study provides the park with enough research/information to identify potentially eligible resources that will need further Section 110 inventory/analysis to confirm eligibility before forwarding to the SHPOs office for review and concurrence.

Some of the management actions proposed under Alternative 2 would affect known historic resources 

through demolition, alteration, and relocation related to restoration, construction, and facilities 

removal. Identified historic resources that would be affected by Alternative 2 include the Merced Lake 

High Sierra Camp, Camp Curry Historic District, the Yosemite Valley Historic District, the Yosemite 

Valley Bridges Historic District, the Yosemite Village Historic District, and the Wawona Hotel and 

Pavilion Historic District. Table 9-222 summarizes the impacts to these historic resources. These 

impacts would include altering character-defining features or historic context, or potentially 

demolishing National Register-listed or eligible resources. These actions could have long-term, 

negligible to major adverse effects on individual historic buildings and sites, and minor to moderate 

impacts on historic districts under NEPA. The proposed demolition of the Merced Lake High Sierra 

Camp Historic District would result in an adverse effect under NHPA, and alteration of contributing 

resources to the Yosemite Valley, Yosemite Village, Yosemite Bridges, and Camp Curry Historic Districts 

would potentially diminish the integrity of these resources, resulting in an adverse effect under NHPA. 

Cumulative Impacts from Alternative 2: Self-Reliant Visitor Experiences and Extensive

Past Actions 

Past actions have resulted in a range of beneficial and adverse impacts. Beneficial impacts of past 

actions include extensive actions to preserve and maintain historic resources, including the Camp 

Curry Historic District (Curry Village Registration Building, Guest Lounge and Amphitheater 

Rehabilitation), as well as restoration of meadows associated with the Yosemite Valley Historic 

District (Cook's Meadow). Adverse effects include the removal of the NR eligible Cascades area 

houses. 

Present Actions 

Present actions contribute to a mixture of beneficial and adverse impacts. These impacts include 

efforts to restore, preserve, and protect the historic integrity and character-defining features of The 

Ahwahnee NHL while completing long-term rehabilitation of the building and associated features, 

construction of the Wawona fire station, Camp 4 relocating eight campsites, and the Ahwahnee Hotel 

Porte Cochère Access Walkways and Fence project. Additionally, the park has established the Curry 

Village Rockfall Hazard Zone, which has resulted in the loss of historic structures. These structures are

Cabins with Bath Structures, seismic upgrade to the Ahwahnee Dormitory, and efforts to stabilize the 

floor of the Ahwahnee Hotel, all consist of potential future actions with the potential to affect historic 

resources within the park. 

Overall Cumulative Impact 

Alternative 2 would involve the demolition or alteration of several historic properties (Lake High 

Sierra Camp Historic District, Camp Curry Historic District, Yosemite Village Historic District, and 

Yosemite Valley Bridges Historic District). Additionally, actions common to Alternatives 2–6 would 

involve the relocation or alteration of several National Register-eligible or listed structures (the NR 

Ahwahnee Hotel, Superintendent’s House [Residence 1], Camp Curry Historic District, and Camp 4 ]). 

The removal of the Merced Lake High Sierra Camp Historic District, relocation of the Superintendent’s 

House, loss of nearly half of the contributing bridges of the Yosemite Valley Bridges Historic District, 

and the loss of resources in the Curry Village Area of the Yosemite Valley Historic District would 

potentially result in a long-term, major, adverse impact on both the individual cultural resources and

Merced Lake High Sierra Camp Historic District 

The conversion of the Merced Lake High Sierra Camp to a temporary pack camp and removal of the infrastructure would adversely affect contributors to the Merced Lake High Sierra Camp Historic District. 

The Merced Lake High Sierra Camp is considered significant in recreation and education as one of seven high country camps whose origin dates back to the earliest days of the National Park Service. The Yosemite camp system initially began in 1916 as an effort to attract people into the park’s high country. Through the use of organized parties guided by a Yosemite naturalist, the Park Service established a unique pattern of interpretive service in the high country of one of the most populous national parks, which helped acquaint the American public with the conservation objectives of the agency in all natural areas of the system (Criterion A, association with historic events) (Kirk, 2004). NEPA: The alteration or removal of historic period buildings and structures in the Merced Lake High Sierra Camp area would greatly alter the Merced Lake High Sierra Camp Historic District to the point of delisting the district from the National Register. The Merced Lake High Sierra Camp Historic District is one of the few National Register-eligible resources in Segment 1. The removal of contributing resources of an eligible historic district represents a substantial and highly noticeable change in character-defining features and the permanent alteration of the historic setting and character of the segment. While the action would be completed consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation), the proposed action would result in a major, long term, local adverse impact on the district under NEPA and potential delisting of the district.

Impacts of Actions to Protect and Enhance River Values 

Table 9-224 describes impacts of actions intended to protect and enhance river values in Segment 2 

under Alternative 3. 

Biological Resource Actions. Biological resource actions to protect and enhance river values in 

Segment 2 under Alternative 3 would result in moderate, local, long term adverse impact on the listed 

Yosemite Valley Historic District under NEPA through impacts to the contributing resources of 

Southside Drive, Boys Town, Valley Loop Trail, and Slaughterhouse Meadow, and an adverse effect to 

the Yosemite Valley Historic District under NHPA. No NHL would be affected. 

Hydrologic/Geologic Resource Actions. Hydrologic/geologic resource actions to protect and 

enhance river values in Segment 2 under Alternative 3 would result in major, long term, local, adverse 

impacts on both the Yosemite Valley Bridges Historic District and the Yosemite Valley Historic District 

under NEPA through impacts to the contributing resources of Sugar Pine Bridge, Ahwahnee Bridge, 

Stoneman Bridge, and an adverse effect on the Yosemite Valley Historic District and Yosemite Valley 

Bridges Historic District under NHPA. No NHL would be affected. 

Cultural Resource Actions. Cultural resource actions to protect and enhance river values in Segment 2 

under Alternative 3 would result in a moderate, long term, local, beneficial impact on the Yosemite 

Valley and Yosemite Village Historic Districts under NEPA, and no adverse effect on the Yosemite 

Valley and Yosemite Village Historic Districts under NHPA through impacts resulting from the 

stabilization of the contributing resource of the Superintendent’s House. No NHL would be affected. 

Impacts of Actions to Manage User Capacities, Land Use, and Facilities 

Table 9-225 describes impacts of actions intended to manage visitor use and facilities in Segment 2 

under Alternative 3. 

Curry Village. Project level actions to manage visitor use and facilities in the Curry Village area would 

include the re redesign of the Curry Orchard parking area, and rerouting Southside Drive through 

Boys Town. Programmatic actions to manage visitor use and facilities include the reduction of the 

Curry Village Stables. As described in Table 9-225 below, actions to remove housing, reduce the 

stables, reroute Southside Drive, and alter the Curry Orchard Parking area would result in a long term, 

local, moderate to minor adverse effect to the Yosemite Valley Historic District under NEPA. These 

actions would result in an adverse effect to the Yosemite Valley Historic District through alterations to 

contributing historic properties under NHPA. 

Yosemite Lodge and Camp 4. Project level actions to manage visitor use and facilities in the Yosemite 

Lodge and Camp 4 areas would include alterations to Yosemite Lodge, such as the redesign of parking 

areas, removal of existing buildings and facilities, construction of new employee housing, and 

repurposing of existing buildings. As described in table 9-225 below, Yosemite Lodge was identified as 

being a non-contributing site within the Yosemite Valley Historic District. However, it has not been 

evaluated for its post-WWII significance under the 50-year rule for the inventorying of historic

The restoration of Stoneman Meadow including the realignment of Southside Drive would affect historic circulation patterns in the Curry Village Area of the Yosemite Valley Historic District. This action would, however, improve Stoneman Meadow, another contributor to the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is 

nationally significant in the themes of outdoor recreation, tourism, and conservation. Many recreational trends, including sightseeing, camping, auto camping, mountaineering, winter sports, and others began or were significantly advanced at Yosemite (Criterion A). The cultural landscape of Yosemite Valley features nationally significant examples of architecture. Camp Curry is a rare example of a surviving tent cabin complex of the type that was once common in many parks (Criterion C). The historic circulation of Camp Curry is predominantly pedestrian, with vehicular approaches from the west (Old Village) and northwest (Stoneman Bridge). Today vehicular access is limited mainly to the northwestern approach, and the western approach has been converted to parking and foot trail. Since the original entry was oriented to this entrance, the historic gateway has become somewhat obsolete, at least in the current circulation configuration. Stoneman Meadow is a contributing site to the Yosemite Valley Historic District as a characteristic landscape feature in the Valley, as is Southside Drive (NPS 2006d). Southside Drive is not considered a contributor to the Camp Curry Historic District (Hart, 1979). NEPA: The realignment of Southside Drive through Boys Town would affect the Yosemite Valley Historic District through alteration of historic circulation patterns in Curry Village and in the Valley. The action will not, however, result in an adverse impact to the historic approach to the Curry Village area, which is the focus of remaining historic vehicular circulation. The road 

realignment will include a small segment of the entire length of Southside Drive, in an area not out of character with its existing route. Additionally, the restoration of Stoneman Meadow to a more historic setting would have a beneficial impact on the Yosemite Valley Historic District. Finally, the action would comply with guidance to be established through development of a Programmatic Agreement for the Merced River Plan or standard 36 CFR Part 800 consultation. The proposed action will have a moderate, local, long term adverse impact on the listed Yosemite Valley Historic District under NEPA.

Yosemite Valley Historic District (2004001159) 

Rerouting the Valley Loop Trail through Slaughterhouse Meadow has the potential to affect both these contributors to the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. Valley Loop Trail is one of the primary trails originating in the valley. The Valley Loop Trail dates from the 1920s and was originally built as a bridle trail, generally aligned along existing circulation routes. Thirteen additional miles were added to the Valley Loop Trail in 1928, requiring the construction of 14 bridges. Today, the Valley Loop Trail includes the entire remaining bridle trail system in the valley and it is approximately 21 miles long (Criterion A). The Slaughterhouse Meadow is a contributing site to the Yosemite Valley Historic District as a characteristic landscape feature in the Valley (NPS 2006d). Both the Valley Loop Trail and Slaughterhouse meadow are contributors to the National Register-listed Yosemite Valley Historic District. Rerouting the Valley Loop Trail could alter both of these resources. Any sections of Valley Loop Trail that would be rerouted would require additional analysis prior to construction or demolition. The action would comply with guidance to be established through development of a Programmatic Agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation). A determination of effect under both NEPA and NHPA would occur after a determination of eligibility is completed and concurred upon by SHPO during future site planning.

Yosemite Valley Bridges Historic District (1977000160); Yosemite Valley Historic District (2004001159) 

Removal of Stoneman Bridge, redesign of Sentinel intersection, removal of the Ahwahnee and Sugar Pine Bridges, and restoration to natural conditions would remove contributing structures to the Yosemite Valley Bridges and Yosemite Valley Historic Districts. 

Bridges have been a major component of the cultural landscape of the Yosemite Valley from the first years of non-indigenous settlement. The Yosemite Valley Bridges Historic District consists of 8 granite-faced, concrete arch road bridges on the Valley floor, constructed between 1921 and 1933. The Valley bridges are unique for their architectural design and aesthetic considerations, representing an effort to build structures in the national parks which are simple and uniform in design to blend in with the environment (Criterion C) (Wilson, 1977). This bridge is also a contributor to the Yosemite Valley Historic District. NEPA: The demolition and removal of Stoneman, Ahwahnee, and Sugar Pine Bridges would alter the Yosemite Valley Historic District and the Yosemite Valley Bridges Historic District. The loss of the bridges would result in the loss of nearly half of the contributing resources in the National Register-listed Yosemite Valley Bridges Historic District. This would also result in the loss of several of the major Merced River crossings within the Yosemite Valley Historic District. The action would be implemented with either the proposed Merced River Plan programmatic agreement or standard 36 CFR Part 800 consultation. The proposed actions would result in a major, long term, local, adverse impact on the Yosemite Valley Bridges Historic District and the Yosemite Valley Historic District under NEPA. NHPA: The demolition and removal of Stoneman, Ahwahnee, and Sugar Pine Bridges would result in the loss of nearly half of the contributing resources in the National Register-listed Yosemite Valley Bridges Historic District and the Yosemite Valley Historic District.

El Portal The construction of additional 

concessioner housing in the Rancheria area of El Portal has the potential to alter the historic setting of potential historic resources in El Portal. 

El Portal is a small community comprised of 1200 acres of land on both the north and south sides of the Merced River and Highway 140. In 1961 the National Park Service began building housing in Rancheria Flat, west of El Portal as part of the Mission 66 initiative in the National Park Service. The Rancheria Mission 66 area has been recommended as a historic district as part of a historic resource study identifying potentially eligible properties in El Portal, but has not yet received SHPO concurrence (NPS 2011r). The construction of new housing in the Rancheria area of El Portal has the potential to alter the historic setting of the area and any potential historic resources not currently eligible or listed by the Park. A historic resource study identifying potentially eligible properties in the vicinity of El Portal has been completed by park staff (NPS 2011r). This study provides the park with enough research/information to identify potentially eligible resources that will need further Section 110 inventory/analysis to confirm eligibility before forwarding to the SHPOs office for review and concurrence.

Impacts of Actions to Manage User Capacities, Land Use, and Facilities 

Table 9-227 describes impacts of actions intended to manage visitor use and facilities in Segments 5, 6, 

7, and 8 under Alternative 3. 

Summary of Impacts from Alternative 3: Dispersed Visitor Experiences and Extensive 

Riverbank Restoration 

Some of the management actions proposed for Alternative 3 could have adverse effects on known 

historic resources through demolition, alteration, and relocation related to restoration, construction, 

and facilities removal. Identified historic resources that would be affected by Alternative 3 include the 

Merced Lake High Sierra Camp, Camp Curry Historic District, the Yosemite Valley Historic District, 

Camp 4, the Ahwahnee Hotel, the Yosemite Valley Bridges Historic District, the Pioneer Yosemite 

History Center, and the Wawona Hotel and Pavilion Historic District. Table 9-228 summarizes the 

impacts to these historic resources. These actions could have long-term, minor to moderate adverse 

effects on individual historic buildings and sites, and moderate to major adverse effects on historic 

districts under NEPA. The proposed demolition of the Merced Lake High Sierra Camp Historic 

District would result in an adverse effect under NHPA, and actions resulting in the alteration of 

contributing resources to the Camp Curry Village, Yosemite Bridges, or the Yosemite Valley Historic 

Districts would diminish the integrity of these districts and result in an adverse effect under NHPA. 

Cumulative Impacts from Alternative 3: Dispersed Visitor Experiences and Extensive 

Riverbank Restoration 

Past Actions 

Past actions have resulted in a range of beneficial and adverse impacts. Beneficial impacts of past 

actions include extensive actions to preserve and maintain historic resources, including the Camp 

Curry Historic District (Curry Village Registration Building, Guest Lounge and Amphitheater 

Rehabilitation), as well as restoration of meadows associated with the Yosemite Valley Historic 

District (Cook's Meadow). Adverse effects include the removal of the NR eligible Cascades area 

houses. 

Present Actions 

Present actions contribute to a mixture of beneficial and adverse impacts. These impacts include 

efforts to restore, preserve, and protect the historic integrity and character-defining features of The 

Ahwahnee NHL while completing long-term rehabilitation of the building and associated features, 

construction of the Wawona fire station, Camp 4 relocating eight campsites, and the Ahwahnee Hotel 

Porte Cochère Access Walkways and Fence project. Additionally, the park has established the Curry 

Village Rockfall Hazard Zone, which has resulted in the loss of historic structures. These structures are 

being documented under a separate MOA.

Wawona Hotel and Pavilion 

The removal of the tennis courts would affect potential contributors to the National Register Wawona Hotel and Pavilion District. 

The Wawona Hotel and Pavilion's architectural importance to American architecture is as the largest existing Victorian hotel complex within the boundaries of a national park, and one of the few remaining in the United States with this high level of integrity (Criterion C). The removal of the Wawona tennis courts would potentially affect the NR WHPHD. The Wawona tennis courts have not been previously evaluated as a National Register-eligible resource, either contributing or individually. Removal of facilities in this location would result in a potentially adverse effect. The Park will complete NHPA section 110 prior to this action, with a DOE completed prior to site planning. Additional consultation (tribal or SHPO) would also be required. In the event that the property is found eligible, planning and design efforts would be reassessed prior to construction in order to ensure that the park has attempted to avoid, minimize or mitigate any potentially adverse impacts to the historic property. This action would be completed in compliance with guidance to be established through development of a Programmatic Agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation), without this above described analysis. A determination of effect under both NEPA and NHPA would occur after a determination of eligibility is completed and concurred upon by SHPO during future site planning.

Impacts from future actions would be similar to those discussed for past and present actions as a mix 

of beneficial and adverse impacts to historic resources. The Curry Village Rehabilitation of Historic 

Cabins with Bath Structures, seismic upgrade to the Ahwahnee Dormitory, and efforts to stabilize the 

floor of the Ahwahnee Hotel, all consist of potential future actions with the potential to affect historic 

resources within the park. 

Overall Cumulative Impact 

Alternative 3 would involve the demolition or alteration of several National Register-eligible, listed, or 

National Register structures (Merced Lake High Sierra Camp Historic District, Wawona Hotel and 

Pavilion Historic District, Yosemite Valley Historic District, and Yosemite Valley Bridges Historic 

District). Additionally, actions common to Alternatives 2–6 would involve the relocation or alteration 

of several National Register-eligible or listed structures (the NR Ahwahnee Hotel, Superintendent’s 

House [Residence 1], Camp Curry Historic District, and Camp 4 ]). The alteration or removal of these 

resources would potentially result in a long-term, moderate, adverse impact on both the individual 

resources and the cumulative historic fabric of the Merced River corridor. While all site-specific 

planning and compliance actions would be accomplished in accordance with stipulations in the park’s 

proposed Merced River Plan programmatic agreement, the potential effect on the character-defining 

features of historic resources within the Merced River corridor would result in a long-term, moderate, 

adverse cumulative impact on historic resources.

Merced Lake High Sierra Camp Historic District 

The closure of the Merced Lake High Sierra Camp conversion of the site to its natural condition would adversely affect the Merced Lake High Sierra Camp Historic District. 

The Merced Lake High Sierra Camp is considered significant in recreation and education as one of seven high country camps whose origin dates back to the earliest days of the National Park Service. The Yosemite camp system initially began in 1916 as an effort to attract people into the park’s high country. Through the use of organized parties guided by a Yosemite naturalist, the Park Service established a unique pattern of interpretive service in the high country of one of the most populous national parks, which helped acquaint the American public with the conservation objectives of the agency in all natural areas of the system (Criterion A, association with historic events) (Kirk, 2004). NEPA: The alteration or removal of historic period buildings and structures in the Merced Lake High Sierra Camp area would greatly alter the district to the point of delisting the district from the National Register consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation)local adverse impact. The Merced Lake High Sierra Camp Historic District is one of the few National Register-eligible resources in Segment 1. The removal of contributing resources of an eligible historic district represents a substantial and highly noticeable change in character-defining features and the permanent alteration of the historic setting and character of the segment. While the action would be completed consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation), the proposed action would result in a major, long term, local adverse impact on the district under NEPA and potential delisting of the district. NHPA: The alteration or removal of historic period buildings and structures in the Merced Lake High Sierra Camp area would greatly alter the Merced Lake High Sierra Camp Historic District to the point of delisting the district from the National Register. The Merced Lake High Sierra Camp Historic District is one of the few National Register-eligible resources in Segment 1. The removal of contributing resources of an eligible historic district represents a substantial and highly noticeable change in character-defining features and the permanent alteration of the historic setting and character of the segment. The action would be completed consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan or standard 36 CFR Part 800 consultation.

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. The El Captain Meadow is a contributing site to the Yosemite Valley Historic District as a characteristic landscape feature in the Valley (NPS 2006d). NEPA: The restoration of the meadow to its historic setting would result in a long term, local, beneficial effect to the Yosemite Valley Historic District under NEPA.

The restoration of Stoneman Meadow including the realignment of Southside Drive would affect historic circulation patterns in the Curry Village Area of the Yosemite Valley Historic District. This action would, however, improve Stoneman Meadow, another contributor to the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. Many recreational trends, including sightseeing, camping, auto camping, mountaineering, winter sports, and others began or were significantly advanced at Yosemite (Criterion A). The cultural landscape of Yosemite Valley features nationally significant examples of architecture. Camp Curry is a rare example of a surviving tent cabin complex of the type that was once common in many parks (Criterion C). The historic circulation of Camp Curry is predominantly pedestrian, with vehicular approaches from the west (Old Village) and northwest (Stoneman Bridge). Today vehicular access is limited mainly to the northwestern approach, and the western approach has been converted to parking and foot trail. Since the original entry was oriented to this entrance, the historic gateway has become somewhat obsolete, at least in the current circulation configuration. Stoneman Meadow is a contributing site to the Yosemite Valley Historic District as a characteristic landscape feature in the Valley, as is Southside Drive (NPS 2006d). NEPA: The realignment of Southside Drive through Boys Town would affect the Yosemite Valley Historic District through alteration of historic circulation patterns in Curry Village and in the Valley.

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. Valley Loop Trail is one of the primary trails originating in the valley. The Valley Loop Trail dates from the 1920s and was originally built as a bridle trail, generally aligned along existing circulation routes. Thirteen additional miles were added to the Valley Loop Trail in 1928, requiring the construction of 14 bridges. Today, the Valley Loop Trail includes the entire remaining bridle trail system in the valley and it is approximately 21 miles long (Criterion A). The Slaughterhouse Meadow

In order to address river flow concerns, Stoneman Bridge would be left in place, but engineer solutions, such as installation of large wood or culverts to Northside Drive, would be installed. This would result in an effect to a contributing structure to these historic districts. 

Bridges have been a major component of the cultural landscape of the Yosemite Valley from the first years of Non-indigenous settlement. The Yosemite Valley Bridges Historic District consists of 8 granite-faced, concrete arch road bridges on the Valley floor, constructed between 1921 and 1933. The Valley bridges are unique for their architectural design and aesthetic considerations, representing an effort to build structures in the national parks which are simple and uniform in design to blend in with the environment (Criterion C) (Wilson, 1977). This bridge is also a contributor to the Yosemite Valley Historic District. NEPA: The installation of engineered solutions in the vicinity of Stoneman Bridge may alter the historic setting of a contributor to the historic Yosemite Valley Bridges Historic District and Yosemite Valley Historic District. If culverts were installed in the vicinity of Stoneman Bridge, the culverts would be installed following Yosemite Design Guidelines and mitigation measure HIST-1, and with guidance to be established through development of a Programmatic Agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation) and should not affect the historic setting of the bridge, resulting in a negligible, long-term, local, adverse impact on the Yosemite Valley Bridges Historic District and Yosemite Valley Historic District under NEPA.

Cultural Resource Actions. Cultural resource actions to protect and enhance river values in Segment 

2 under Alternative 4 would result in a moderate, long term, local, beneficial impact on the Yosemite 

Valley and Yosemite Village Historic Districts under NEPA, and no adverse effect on the Yosemite 

Valley and Yosemite Village Historic Districts under NHPA through impacts resulting from the 

rehabilitation of the contributing resource of the Superintendent’s House. No NHL would be affected. 

Impacts of Actions to Manage User Capacities, Land Use, and Facilities 

Table 9-231 describes impacts of actions intended to manage visitor use and facilities in Segment 2 

under Alternative 4. 

Curry Village. Project level actions to manage visitor use and facilities in the Curry Village area would 

include the redesign of the Curry Orchard parking area, and rerouting Southside Drive through Boys 

Town and construction of a 40-site campground. As described in table 9-231 below, actions to remove 

housing, redesign Curry Orchard Parking area, and reroute Southside Drive would result in a long 

term, local, moderate adverse impact to the Yosemite Valley Historic District and Camp Curry 

Historic District under NEPA. These actions would result in an adverse effect to the Yosemite Valley 

Historic District and Camp Curry Historic District through alterations to contributing historic 

properties under NHPA.

Yosemite Lodge and Camp 4. Project level actions to manage visitor use and facilities in the Yosemite 

Lodge and Camp 4 areas would include alterations to Yosemite Lodge, such as the redesign of parking 

areas, removal of existing buildings and facilities, construction of new employee housing, and 

repurposing of existing buildings. As described in table 9-231 below, Yosemite Lodge was identified as 

being a non-contributing site within the Yosemite Valley Historic District. However, it has not been 

evaluated for its post-WWII significance under the 50-year rule for the inventorying of historic 

properties for the National Register, and a determination of effect under both NEPA and NHPA would 

occur after a determination of eligibility is completed and concurred upon by SHPO during future site 

planning. of this action. Impacts to the Yosemite Valley Historic District through the construction of 

new facilities within the district would result in a minor, local, long term adverse impact on the listed 

Yosemite Valley Historic District under NEPA.

Construction of additional housing or facilities would result in an alteration to the setting of the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. The introduction of new permanent buildings, facilities, or additional parking has the potential to alter the setting of the Yosemite Valley Historic District. This includes actions such as increased parking at Lost Arrow and camping at Upper Pines and the former Lower River Campground. The Park will complete NHPA section 110 prior to this action, with a DOE completed prior to site planning. Additional consultation (tribal or SHPO) would also be required. In the event that the property is found eligible, planning and design efforts would be reassessed prior to construction in order to ensure that the park has attempted to avoid, minimize or mitigate any potentially adverse impacts to the historic property. This action would be completed in compliance with the proposed Merced River Plan PA and a determination of effect under both NEPA and NHPA would occur after a determination of eligibility is completed and concurred upon by SHPO and during future site planning.

Manage Visitor Use and Facilities 

Yosemite Valley Historic District (2004001159) 

The re-design of the Curry Orchard Day Use Parking area and extension of the boardwalk through to Curry Village would result in the removal of historic trees and alteration of a contributor to the Yosemite Valley Historic District. Associated restoration of Stoneman Meadow would have no affect on this Yosemite Valley Historic District contributor. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. Many recreational trends, including sightseeing, camping, auto camping, mountaineering, winter sports, and others began or were significantly advanced at Yosemite (Criterion A). The cultural landscape of Yosemite Valley features nationally significant examples of architecture. Camp Curry is a rare example of a surviving tent cabin complex of the type that was once common in many parks (Criterion C). In 1927, the Park addressed a growing problem with parking by converting a nearby apple orchard into a unique parking area for Curry Village. Curry Orchard Day Use Parking area is a contributing site to the Yosemite Valley Historic District, but not the Camp Curry Historic District (NPS 2006d; Hart, 1979).

The action will not, however, result in an adverse effect to the historic approach to the Curry Village area, which is the focus of remaining historic vehicular circulation. The road realignment will include a small segment of the entire length of Southside Drive, in an area not out of character with its existing route. The action does have the potential to alter historic pedestrian circulation through the rerouting of pedestrian paths. The conversion of Boys Town to a campground would also result in the removal of historic tent cabins and structures, altering both the Yosemite Valley and Camp Curry Historic Districts. The action would comply with guidance to be established through development of a Programmatic Agreement for the Merced River Plan (or 36 CFR Part 800 consultation).

The relocation and formalization of the parking to the north of the road and re-routing Northside Drive south of the parking at Yosemite Village Day-Use Parking area would affect historic circulation patterns in the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. Northside and Southside drives create a framework for circulation around the valley, on either side of the Merced River, and are contributing structures to the Yosemite Valley Historic District. The historic circulation of Yosemite Village is predominantly centered on Village Drive between Northside Drive and Village bike path (NPS 2006d). Northside Drive is not a contributor to the Yosemite Village Historic District (Donahoe 1994). NEPA: The formalization of the parking lot will occur within the existing developed former footprint of the Concessioner GO and the Concessioner Garage. The re-routing of Northside Drive would affect the Yosemite Valley Historic District through alteration of historic circulation patterns as well as alteration of a contributing resource (Northside Drive).

Relocation of the Superintendent’s House and garage to the NPS housing 

area and restoration of the area to natural conditions would result in an adverse effect to a contributor to the Yosemite Valley and Yosemite Village Historic Districts. This will occur in addition to the rehabilitation actions described above. 

Yosemite Village has one of the largest and most significant collections of 

NPS Rustic style buildings in the national park system, with both concessioner and NPS buildings representing a range of rustic types and building materials (Criterion 3). The Superintendent’s House and garage

are contributors to the Yosemite Valley Historic District and the Yosemite Village Historic District (Donahoe 1994). NEPA: The relocation of the Superintendent’s House and garage from its 

historic location has the potential to alter the Yosemite Valley and Yosemite Village Historic Districts. The action would be taken consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan or the standard 36 CFR Part 800 consultation. The relocation of a building from its historic location results in the loss of historic contextual setting, and can result in the delisting of the resource from the National Register. Additionally, the introduction of the Superintendent’s House and garage to a new location has the potential to alter the setting of historic resources in that location as well. The relocation of a building within the Yosemite Valley and Yosemite Village Historic Districts would result in a long term, moderate, local, adverse impact. NHPA: The relocation of the Superintendent’s House and garage from its 

isolated historic location would alter the Yosemite Valley and Yosemite Village Historic Districts. The action would be taken consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan or the standard 36 CFR Part 800 consultation. The relocation of the building would result in the loss of historical setting of the resource, resulting in the building no longer being eligible for the National Register.

Yosemite Lodge; Yosemite Valley Historic District 

Construction of new employee housing or parking in the vicinity of Yosemite Lodge or the removal of existing buildings within the flood plain would potentially result in the removal of a historic resource. 

In 1956, the Yosemite Lodge was completely rebuilt and most of the old lodge buildings were demolished. The Yosemite Lodge is almost entirely the product of postwar planning and construction, but has not been evaluated for eligibility as a National Register-eligible resource (NPS 2006d). The construction of additional employee housing or parking in the vicinity of Yosemite Lodge or removal of existing buildings could affect historic resources, including the Yosemite Valley Historic District. Yosemite Lodge has not been previously evaluated as a National Register-eligible resource. Addition of new facilities or removal of existing buildings in this location potentially would alter the Yosemite Valley Historic District.

El Portal is a small community comprised of 1200 acres of land on both the north and south sides of the Merced River and Highway 140. In 1961 the National Park Service began building housing in Rancheria Flat, west of El Portal as part of the Mission 66 initiative in the National Park Service. The Rancheria Mission 66 area has been recommended as a historic district as part of a historic resource study identifying potentially eligible properties in El Portal, but has not yet received SHPO concurrence (NPS 2011r). The construction of new housing in the Rancheria area of El Portal has the potential to alter the historic setting of the area and any potential historic resources not currently eligible or listed by the Park. A historic resource study identifying potentially eligible properties in the vicinity of El Portal has been completed by park staff (NPS 2011r). This study provides the park with enough research/information to identify potentially eligible resources that will need further Section 110 inventory/analysis to confirm eligibility before forwarding to the SHPOs office for review and concurrence.

Alternative 4 would result in fewer adverse effects on historic resources than under Alternatives 2 and 

3; however, some of the management actions proposed with Alternative 4 could adversely affect 

known historic resources through demolition, alteration, and relocation related to restoration, 

construction, and facilities removal. Identified historic resources that would be affected by 

Alternative 4 include the Merced Lake High Sierra Camp, Camp Curry Historic District, NR 

Ahwahnee Hotel, Camp 4, Yosemite Valley Historic District, and the Yosemite Valley Bridges Historic 

District. Table 9-234 summarizes the impacts to these historic resources. These impacts would include 

altering the character-defining features or historic context, or potentially demolishing National 

Register-listed resources or eligible resources. These actions could cause long-term, moderate, local, 

adverse impacts on historic buildings and sites, and minor to moderate adverse impacts on historic

Cumulative Impacts from Alternative 4: Resource-Based Visitor Experiences and Targeted 

Riverbank Restoration 

Past Actions 

Past actions have resulted in a range of beneficial and adverse impacts. Beneficial impacts of past 

actions include extensive actions to preserve and maintain historic resources, including the Camp 

Curry Historic District (Curry Village Registration Building, Guest Lounge and Amphitheater 

Rehabilitation), as well as restoration of meadows associated with the Yosemite Valley Historic 

District (Cook's Meadow). Adverse effects include the removal of the NR eligible Cascades area 

houses. 

Present Actions 

Present actions contribute to a mixture of beneficial and adverse impacts. These impacts include 

efforts to restore, preserve, and protect the historic integrity and character-defining features of The 

Ahwahnee NHL while completing long-term rehabilitation of the building and associated features, 

construction of the Wawona fire station, Camp 4 relocating eight campsites, and the Ahwahnee Hotel 

Porte Cochère Access Walkways and Fence project. Additionally, the park has established the Curry 

Village Rockfall Hazard Zone, which has resulted in the loss of historic structures. These structures are 

being documented under a separate MOA. 

Future Actions 

Impacts from future actions would be similar to those discussed for past and present actions as a mix 

of beneficial and adverse impacts to historic resources. The Curry Village Rehabilitation of Historic 

Cabins with Bath Structures, seismic upgrade to the Ahwahnee Dormitory, and efforts to stabilize the 

floor of the Ahwahnee Hotel, all consist of potential future actions with the potential to affect historic 

resources within the park. 

Overall Cumulative Impact 

Alternative 4 would involve the demolition or alteration of several National Register-eligible or -listed 

structures and historic districts (Merced Lake High Sierra Camp Historic District, Yosemite Valley 

Historic District, and Yosemite Valley Bridges Historic District). Additionally, actions common to 

Alternatives 2–6 would involve the relocation or alteration of several National Register-eligible, listed, 

or National Historic Landmark structures (the NR Ahwahnee Hotel, Superintendent’s House 

[Residence 1], Camp Curry Historic District, and Camp 4). The alteration or removal of these resources 

would potentially result in a long-term, moderate, adverse impact on both the individual cultural 

resources and the cumulative historic fabric of the Merced River corridor. While all site-specific 

planning and compliance actions would be accomplished in accordance with stipulations in the park’s 

proposed Merced River Plan programmatic agreement, the potential effect on the character-defining 

features of historic resources within the river corridor would result in a long-term, moderate adverse 

cumulative effect on historic resources.

Merced Lake High Sierra Camp Historic District 

The reduction of the number of beds at the Merced Lake High Sierra Camp to 11 units (of an original 22) would not adversely affect the Merced Lake High Sierra Camp Historic District. 

The Merced Lake High Sierra Camp is considered significant in recreation and education as one of seven high country camps whose origin dates back to the earliest days of the National Park Service. The Yosemite camp system initially began in 1916 as an effort to attract people into the park’s high country. Through the use of organized parties guided by a Yosemite naturalist, the Park Service established a unique pattern of interpretive service in the high country of one of the most populous national parks, which helped acquaint the American public with the conservation objectives of the agency in all natural areas of the system (Criterion A) (Kirk, 2004). NEPA: The Merced Lake High Sierra Camp Historic District is one of the

Rerouting the Valley Loop Trail, including the construction of boardwalks through sensitive habitat in Slaughterhouse Meadow, has the potential to affect both these contributors to the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is 

nationally significant in the themes of outdoor recreation, tourism, and conservation. Valley Loop Trail is one of the primary trails originating in the valley. The Valley Loop Trail dates from the 1920s and was originally built as a bridle trail, generally aligned along existing circulation routes. Thirteen additional miles were added to the Valley Loop Trail in 1928, requiring the construction of 14 bridges. Today, the Valley Loop Trail includes the entire remaining bridle trail system in the valley and it is approximately 21 miles long (Criterion A). The Slaughterhouse Meadow is a contributing site to the Yosemite Valley Historic District as a characteristic landscape feature in the Valley (NPS 2006d). Both the Valley Loop Trail and Slaughterhouse meadow are contributors to the National Register-listed Yosemite Valley Historic District. Rerouting the Valley Loop Trail could alter these historic resources. Any sections of Valley Loop Trail that would be rerouted would require additional analysis prior to construction or demolition.

Construction of new employee housing or parking in the vicinity of Yosemite Lodge or the removal of existing buildings within the floodplain would potentially result in the removal of a historic resource. 

In 1956, the Yosemite Lodge was completely rebuilt and most of the old lodge buildings were demolished. The Yosemite Lodge is almost entirely the product of postwar planning and construction (NPS 2006d). NEPA: The construction of additional employee housing or parking in the vicinity of Yosemite Lodge or removal of existing buildings could impact historic resources. Yosemite Lodge has not been evaluated for NR eligibility as a Mission 66 resource. The park will complete a Determination of Eligibility prior to implementing the selected action.

El Portal Historic Structures 

The construction of additional concessioner housing in the Rancheria area of El Portal has the potential to alter the historic setting of potential historic resources in El Portal. 

El Portal is a small community comprised of 1200 acres of land on both the north and south sides of the Merced River and Highway 140. In 1961 the National Park Service began building housing in Rancheria Flat, west of El Portal as part of the Mission 66 initiative in the National Park Service. A draft historic resource study for El Portal has identified the Rancheria Mission 66 complex as being potentially eligible for listing in the National Register. A Section 110 inventory would need to be completed prior to site planning (NPS 2011r). The construction of new housing in the Rancheria area of El Portal has the potential to alter the historic setting of the area and any potential historic resources not currently eligible or listed by the Park. A historic resource study identifying potentially eligible properties in the vicinity of El Portal has been completed by park staff (NPS 2011r). This study provides the park with enough research/information to identify potentially eligible resources that will need further Section 110 inventory/analysis to confirm eligibility before forwarding to the SHPOs office for review and concurrence.

Summary of Impacts from Alternative 5: Enhanced Visitor Experiences and Essential River 

Bank Restoration

Alternative 5 would result in fewer adverse effects on historic resources than Alternatives 2, 3, or 4; 

however, some of the management actions proposed for Alternative 5 could have adverse effects on 

known historic resources through demolition, alteration, and relocation related to restoration, 

construction, and facilities removal. Identified historic resources that would be affected by Alternative 5 

include the Camp Curry Historic District, the Yosemite Valley Historic District, Yosemite Village 

Historic District, and the Yosemite Valley Bridges Historic District. Table 9-239 summarizes the 

impacts to these historic resources. These impacts would include the alteration of character-defining 

features or historic context, or potential demolition of National Register-listed resources or eligible 

resources.

Past Actions 

Past actions have resulted in a range of beneficial and adverse impacts. Beneficial impacts of past 

actions include extensive actions to preserve and maintain historic resources, including the Camp 

Curry Historic District (Curry Village Registration Building, Guest Lounge and Amphitheater 

Rehabilitation), as well as restoration of meadows associated with the Yosemite Valley Historic 

District (Cook's Meadow). Adverse effects include the removal of the NR eligible Cascades area 

houses. 
AFFECTED ENVIRONMENT AND ENVIRONMENTAL CONSEQUENCES

9-1250 Merced Wild and Scenic River Comprehensive Management Plan / DEIS

Present Actions 

Present actions contribute to a mixture of beneficial and adverse impacts. These impacts include efforts 

to restore, preserve, and protect the historic integrity and character-defining features of The Ahwahnee 

NHL while completing long-term rehabilitation of the building and associated features, construction of 

the Wawona fire station, Camp 4 relocating eight campsites, and the Ahwahnee Hotel Porte Cochère 

Access Walkways and Fence project. Additionally, the park has established the Curry Village Rockfall 

Hazard Zone, which has resulted in the loss of historic structures. These structures are being 

documented under a separate MOA. 

Future Actions 

Impacts from future actions would be similar to those discussed for past and present actions as a mix 

of beneficial and adverse impacts to historic resources. The Curry Village Rehabilitation of Historic 

Cabins with Bath Structures, seismic upgrade to the Ahwahnee Dormitory, and efforts to stabilize the 

floor of the Ahwahnee Hotel, all consist of potential future actions with the potential to affect historic 

resources within the park. 

Overall Cumulative Impact 

Alternative 5 would involve the demolition or alteration of several National Register-eligible or -listed 

structures and historic districts (Merced Lake High Sierra Camp, the Yosemite Valley Historic 

District, Yosemite Village Historic District, and Yosemite Valley Bridges Historic District). 

Additionally, actions common to Alternatives 2–6 would involve the relocation or alteration of several 

National Register-eligible, listed, or National Historic Landmark structures (the NR Ahwahnee Hotel, 

Superintendent’s House [Residence 1], Camp Curry Historic District, and Camp 4). The alteration or 

removal of these resources would potentially result in a long-term, moderate, adverse impact on both 

the individual cultural resources and the cumulative historic character of the Merced River corridor. 

While all site-specific planning and compliance actions would be accomplished in accordance with 

stipulations in the park’s proposed Merced River Plan programmatic agreement, the potential effect 

on the character-defining features of historic resources within the river corridor would result in longterm, moderate, local adverse cumulative impacts on historic resources.

Table 9-240 describes impacts of actions intended to protect and enhance river values in Segment 2 

under Alternative 6. 

Biological Resource Actions. Biological resource actions to protect and enhance river values in 

Segment 2 under Alternative 6 would result in moderate or beneficial, local, long term adverse impacts 

on the listed Yosemite Valley Historic District under NEPA through impacts to the contributing 

resources of Valley Loop Trail, Slaughterhouse and Bridalveil Meadows, and an adverse effect to the 

Yosemite Valley Historic District under NHPA. No NHL would be affected. 

Hydrologic/Geologic Resource Actions. Hydrologic/geologic resource actions to protect and 

enhance river values in Segment 2 under Alternative 6 would result in minor adverse impact on both 

the Yosemite Valley Bridges Historic District and the Yosemite Valley Historic District under NEPA, 

and no adverse effect on the Yosemite Valley Historic District or Yosemite Valley Bridges Historic 

District under NHPA. No NHL would be affected. 

Cultural Resource Actions. Cultural resource actions to protect and enhance river values in Segment 

2 under Alternative 6 would result in a negligible, long term, local, adverse impact on the Yosemite 

Valley and Yosemite Village Historic Districts under NEPA, and no adverse effect on the Yosemite 

Valley or Yosemite Village Historic Districts under NHPA through impacts resulting from the 

rehabilitation of the contributing resource of the Superintendent’s House. No NHL would be affected.

Restoration of El Captain Meadow would result in no adverse effect to the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is nationally significant in the themes of outdoor recreation, tourism, and conservation. The El Captain Meadow is a contributing site to the Yosemite Valley Historic District as a characteristic landscape feature in the Valley (NPS 2006d). NEPA: The restoration of the meadow to its historic setting would result in a long term, local, beneficial effect to the Yosemite Valley Historic District under NEPA. NHPA: The restoration of the meadow would improve the condition of a resource and would result in no adverse effect to the Yosemite Valley Historic District under NHPA.

Rerouting the Valley Loop Trail, including the construction of boardwalks through sensitive habitat in Slaughterhouse and Bridalveil Meadows, has the potential to affect both these contributors to the Yosemite Valley Historic District. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is 

nationally significant in the themes of outdoor recreation, tourism, and conservation. Valley Loop Trail is one of the primary trails originating in the valley. The Valley Loop Trail dates from the 1920s and was originally built as a bridle trail, generally aligned along existing circulation routes. Thirteen additional miles were added to the Valley Loop Trail in 1928, requiring the construction of 14 bridges. Today, the Valley Loop Trail includes the entire remaining bridle trail system in the valley and it is approximately 21 miles long (Criterion A). The Slaughterhouse Meadow is a contributing site to the Yosemite Valley Historic District as a characteristic landscape feature in the Valley (NPS 2006d). The Valley Loop Trail and Slaughterhouse and Bridalveil Meadows are contributors to the National Register-listed Yosemite Valley Historic District. Rerouting the Valley Loop Trail could alter these historic resources. Any sections of Valley Loop Trail that would be rerouted would require additional analysis prior to construction or demolition. The action would comply with guidance to be established through development of a Programmatic Agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation)), but without the above described analysis. A determination of effect under both NEPA and NHPA would occur after a determination of eligibility is completed and concurred upon by SHPO during future site planning.

Yosemite Valley Bridges Historic District (1977000160), Yosemite Valley Historic District (2004001159) 

In order to address river flow concerns, Stoneman Bridge would be left in place, but engineer solutions, such as installation of large wood or culverts to Northside Drive would be installed. In the event that these solutions do not resolve impacts to the condition of the river, more aggressive solutions may be pursues. This would result in an effect to a contributing structure to this historic district. 

Bridges have been a major component of the cultural landscape of the Yosemite Valley from the first years of Non-indigenous settlement. The Yosemite Valley Bridges Historic District consists of 8 granite-faced, concrete arch road bridges on the Valley floor, constructed between 1921 and 1933. The Valley bridges are unique for their architectural design and aesthetic considerations, representing an effort to build structures in the national parks which are simple and uniform in design to blend in with the environment (Criterion C) (Wilson, 1977). This bridge is also a contributor to the Yosemite Valley Historic District. NEPA: The installation of engineered solutions in the vicinity of Stoneman Bridge may alter the historic setting of a contributor to the historic Yosemite Valley Bridges Historic District and Yosemite Valley Historic District. If culverts were installed in the vicinity of Stoneman Bridge, the culverts would be installed following Yosemite Design Guidelines and mitigation measure HIST-1, and should not affect the historic setting of the bridge, resulting in a negligible, long-term, local, adverse impact on the Yosemite Valley Bridges Historic District and Yosemite Valley Historic District under NEPA. NHPA: The installation of engineered solutions in the vicinity of Stoneman Bridge may alter the historic setting of a contributor to the historic Yosemite Valley Bridges Historic District and Yosemite Valley Historic District. If culverts were installed in the vicinity of Stoneman Bridge, the culverts would be installed following Yosemite Design Guidelines and mitigation measure HIST-1, and should not affect the historic setting of the bridge, resulting in no adverse effect to the Yosemite Valley Bridges Historic District or Yosemite Valley Historic District under NHPA. In the event that more aggressive solutions are required, the Park will complete additional site planning to determine the extent of impacts to Stoneman Bridge. While this action would be completed consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan (or standard 36 CFR Part 800 consultation), without finalized designs is not possible to determine the impact of this action under NEPA/NHPA.

Impacts of Actions to Manage User Capacities, Land Use, and Facilities 

Table 9-241 describes impacts of actions intended to manage visitor use and facilities in Segment 2 

under Alternative 6. 

Curry Village. Project level actions to manage visitor use and facilities in the Curry Village area would 

include the replacement of 90 tent cabins and 14 cabins without baths in Boys Town with 78 new hardsided units, and formalizing the Curry Orchard Parking area. As described in table 9-241 below, 

actions to remove housing, formalization of Curry Orchard Parking, and reroute Southside Drive 

would result in a long term, local, major adverse impact to the Camp Curry and Yosemite Valley 

Historic Districts under NEPA. These actions would result in an adverse effect to the Camp Curry and 

Yosemite Valley Historic Districts through alterations to contributing historic properties under 

NHPA. 

Yosemite Lodge and Camp 4. Project level actions to manage visitor use and facilities in the Yosemite 

Lodge and Camp 4 areas would include alterations to Yosemite Lodge, such as the redesign of parking 

areas, removal of existing buildings and facilities, construction of new employee housing, and 

repurposing of existing buildings. As described in table 9-241 below, Yosemite Lodge was identified as 

being a non-contributing site within the Yosemite Valley Historic District. However, it has not been 

evaluated for its post-WWII significance under the 50-year rule for the inventorying of historic 

properties for the National Register, and a determination of effect under both NEPA and NHPA would 

occur after a determination of eligibility is completed and concurred upon by SHPO during future site 

planning. Impacts to the Yosemite Valley Historic District through the construction of new facilities 

within the district would result in a moderate, local, long term adverse impact on the listed Yosemite 

Valley Historic District under NEPA, and no adverse effect under NHPA.

Yosemite Village and Housekeeping Camp. Actions in the Yosemite Village area include the 

relocation and formalization of the parking lot and re-routing Northside Drive at Yosemite Village 

Day-Use Parking area, construction of roundabouts and a pedestrian underpass at Yosemite Village 

Day-Use Parking area, and removal of facilities from Housekeeping Camp. As described in table 9-241

nationally significant in the themes of outdoor recreation, tourism, and conservation. Northside and Southside drives create a framework for circulation around the valley, on either side of the Merced River, and are contributing structures to the Yosemite Valley Historic District. The historic circulation of Yosemite Village is predominantly centered on Village Drive between Northside Drive and Village bike path (NPS 2006d). Northside Drive is not a contributor to the Yosemite Village Historic District (Donahoe 1994).

Yosemite Valley Historic District (2004001159) 

The construction of vehicular roundabouts at Northside Drive and Sentinel Drive (Bank 3-Way) and Northside Drive and Village Drive at Yosemite Village Day-Use Parking area would affect historic circulation patterns. 

The cultural landscape of Yosemite Valley is nationally significant under National Register criteria A and C. The valley floor landscape as a whole is 

nationally significant in the themes of outdoor recreation, tourism, and conservation. Many recreational trends, including sightseeing, camping, auto camping, mountaineering, winter sports, and others began or were significantly advanced at Yosemite (Criterion A). Circulation within Yosemite Valley consists of a variety of vehicular, pedestrian, and equestrian routes. Northside and Southside drives create a framework for circulation around the valley, on either side of the Merced River (NPS 2006d). The historic circulation of Yosemite Village is predominantly centered on Village Drive between Northside Drive and Village bike path (NPS 2006d). Northside Drive is not a contributor to the Yosemite Village Historic District (Donahoe 1994).

Housekeeping Camp Removal of buildings from 

Housekeeping Camp would potentially result in the removal of a historic resource. 

The Housekeeping Camp area developed after 1942, and consists of closely sited, rustic cinderblock and canvas tent cabins. Service buildings include a camp store and laundry and shower facilities, all built after 1942. This area has not been evaluated for eligibility as a National Register-eligible resource. The removal of 34 lodging units and other facilities out of the observed ordinary high water mark could affect historic resources. Housekeeping Camp has not been previously evaluated as a National Register-eligible resource. The Park will complete NHPA section 110 prior to this action, with a DOE completed prior to site planning. Additional consultation (tribal or SHPO) would also be required. In the event that the property is found eligible, planning and design efforts would be reassessed prior to construction in order to ensure that the park has attempted to avoid, minimize or mitigate any potentially adverse impacts to the historic property. This action would be completed consistent with guidance to be established through development of a programmatic agreement for the Merced River Plan or standard 36 CFR Part 800 consultation.

Summary of Impacts from Alternative 6: Diversified Visitor Experiences and Selective 

Riverbank Restoration

Alternative 6 would result in the fewest adverse effects on historic resources; however, some of the 

management actions under Alternative 6 could adversely affect known historic resources through 

demolition, alteration, and relocation related to restoration, construction, and facilities removal. 

Identified historic resources that would be affected by Alternative 6 management actions include the 

Camp Curry Historic District, the Yosemite Valley Historic District, and the Yosemite Valley Bridges 

Historic District. Table 9-244 summarizes the impacts to these historic resources. These impacts 

would include altering character-defining features or historic context, or potentially demolishing 

contributing resources to NRHP-listed or eligible districts. These actions could cause long-term, 

adverse minor effects on historic buildings, sites, and districts.

El Portal The construction of 

additional concessioner housing in the Rancheria area of El Portal has the potential to alter the historic setting of potential historic resources in El Portal. 

El Portal is a small community comprised of 1200 acres of land on both the north and south sides of the Merced River and Highway 140. In 1961 the National Park Service began building housing in Rancheria Flat, west of El Portal as part of the Mission 66 initiative in the National Park Service. The Rancheria Mission 66 area has been recommended as a historic district as part of a historic resource study identifying potentially eligible properties in El Portal, but has not yet received SHPO concurrence (NPS 2011r). The construction of new housing in the Rancheria area of El Portal has the potential to alter the historic setting of the area and any potential historic resources not currently eligible or listed by the Park. A historic resource study identifying potentially eligible properties in the vicinity of El Portal has been completed by park staff (NPS 2011r). This study provides the park with enough research/information to identify potentially eligible resources that will need further Section 110 inventory/analysis to confirm eligibility before forwarding to the SHPOs office for review and concurrence.

Cumulative Impacts from Alternative 6: Diversified Visitor Experiences and Selective 

Riverbank Restoration 

Past Actions 

Past actions have resulted in a range of beneficial and adverse impacts. Beneficial impacts of past 

actions include extensive actions to preserve and maintain historic resources, including the Camp 

Curry Historic District (Curry Village Registration Building, Guest Lounge and Amphitheater 

Rehabilitation), as well as restoration of meadows associated with the Yosemite Valley Historic 

District (Cook's Meadow). Adverse effects include the removal of the NR eligible Cascades area 

houses. 

Present Actions 

Present actions contribute to a mixture of beneficial and adverse impacts. These impacts include 

efforts to restore, preserve, and protect the historic integrity and character-defining features of The 

Ahwahnee NHL while completing long-term rehabilitation of the building and associated features, 

construction of the Wawona fire station, Camp 4 relocating eight campsites, and the Ahwahnee Hotel 

Porte Cochère Access Walkways and Fence project. Additionally, the park has established the Curry 

Village Rockfall Hazard Zone, which has resulted in the loss of historic structures. These structures are 

being documented under a separate MOA. 

Future Actions 

Impacts from future actions would be similar to those discussed for past and present actions as a mix 

of beneficial and adverse impacts to historic resources. The Curry Village Rehabilitation of Historic 

Cabins with Bath Structures, seismic upgrade to the Ahwahnee Dormitory, and efforts to stabilize the 

floor of the Ahwahnee Hotel, all consist of potential future actions with the potential to affect historic 

resources within the park. 
AFFECTED ENVIRONMENT AND ENVIRONMENTAL CONSEQUENCES

Overall Cumulative Impact 

Under Alternative 6, the park would alter several National Register-eligible or -listed structures or 

districts (Yosemite Valley Historic District, Yosemite Valley Bridges Historic District, and Camp Curry 

Historic District). Additionally, actions common to Alternatives 2–6 would involve the relocation or 

alteration of several National Register-eligible, listed, or National Historic Landmark structures (the 

NR Ahwahnee Hotel, Superintendent’s House [Residence 1], Camp Curry Historic District, and 

Camp 4). The alteration of these resources would potentially result in a long-term, minor, adverse 

impact on both the individual cultural resources and the cumulative historic fabric of the Merced 

River corridor. While all site-specific planning and compliance actions would be accomplished in 

accordance with stipulations in the park’s proposed Merced River Plan programmatic agreement, the 

potential effect on the character-defining features of historic resources within the river corridor would 

result in a long-term, moderate adverse cumulative impact on historic resources.
