**FINDING OF NO SIGNIFICANT IMPACT**

**Rehabilitate Superintendent's Residence Project**

# CRATER LAKE NATIONAL PARK

**Oregon**

## Purpose And Need

The National Park Service has elected to rehabilitate the
Superintendent's Residence at Crater Lake National Park headquarters for
the stabilization, preservation, and adaptive reuse of the structure as
part of the park's future science and learning center. The center is
planned as an interdisciplinary facility that would facilitate science
and unite it with place-based learning and appreciation.

The Superintendent's Residence was built in 1932, and completed in 1933.
In 1987, the building was designated a national historic landmark
because it is one of the finest examples of rustic architecture in the
nation. In 1985, a condition assessment was conducted for the
Superintendent's Residence, which described the interior as "in
extremely dilapidated condition." In 1998, a condition survey was
performed on the residence and noted deficiencies in the following
areas: roof structure, roof shakes, roof sheathing, electrical,
structural, and heating and ventilation. At that time, the building was
determined to be uninhabitable, and no renovations were undertaken due
to funding constraints. In 1999, park management conceived the idea to
develop a science and learning center at Crater Lake National Park. Park
management proposed to adaptively reuse the Superintendent's Residence
as a support facility for the new center. During 2002 and 2003, a
historic structures report was developed for the residence that
describes the character-defining features, again assesses the condition
of the structure, and describes the requirements for rehabilitation.
This assessment, along with the proposal for a new park science and
learning center, provided the basis for the selected action.

The selected action involves several repairs and modifications to
interior and exterior features of the Superintendent's Residence.

The selected action is needed and desired for several reasons. First, to
ensure the continued preservation of the structure. Secondly, the
structure, if to be used, needs to be rehabilitated to conform with
applicable safety require­ments, appropriate building codes, and Uniform
Building Accessibility Standards, as warranted. Finally, adaptively
using the structure as part of the science and learning center will
ensure continued maintenance and upkeep with minimal alteration to the
structure.

The National Park Service's selected action (rehabilitation,
preservation, stabilization, and restoration of the Superintendent's
Residence) is alternative B, which is also the preferred alternative in
the environmental assessment. A complete description of alternative B
(the preferred alternative) is found in the "Environmentally Preferred
Alternative" section of the environmental assessment.

## ALTERNATIVES

### Selected Action

The selected action (preferred alternative), adaptive rehabilitation of
the Superintendent's Residence, meets the park's planning objectives of
preserving historic structures, creating universally accessible
facilities, and providing safe and reliable use of existing structures.
The selected action (preferred alternative) will improve drainage around
the structure; strengthen the roof framing and seismic strength;
rehabilitate building systems, power, and lighting; improve
accessibility; provide fire protection; enhance the historic character;
and preserve much of the historic fabric of the Superintendent's
Residence. The structure was originally designed as a residence, the
proposed new function will be considered an adaptive use. The primary
treatment category is rehabilitation. However, overall treatment will
also include preservation, stabilization, and restoration, to varying
degrees, as appropriate.

The rehabilitation of the structure will allow safe use as part of the
park's new science and learning center and will allow access to the
building by all populations. The rehabilitation of the Superintendent's
Residence will require a number of stabilization and repair treatments
including:

-   Driveway -- drainage will be directed away from the garage by
    sloping the pavement in the other direction (if grade allows), or
    installation of a collection system.

-   Architectural -- as needed, interior and exterior finishes will be
    removed, rehabili­tated, or replaced in accordance with the
    *Secretary of the Interior's Standards for Rehabilitation of
    Historic Properties* in order to install structural modifications.
    Some historic treatments and features will be retained; non-historic
    items will be removed. While the ceilings and walls are open, new
    electrical and mechanical treatments will be installed.

-   Interior Architectural Finishes -- historic plaster, woodwork, doors
    and associated hardware, staircase, wood floors, and floor coverings
    will be retained, where possible, and rehabilitated. Non-historic
    elements will be removed and replaced, in accordance with the
    *Secretary of the Interior's Standards for Rehabilitation of
    Historic Properties*, with materials that match the historic fabric.

-   Interior/Exterior Items -- most interior historic light fixtures,
    historic heating supply registers and return grilles, plumbing
    fixtures, steel casement windows, and doors will be rehabilitated.
    Metal primer and paint will be applied to match historic finish
    color. Historic furnishings will be retained, cleaned, and
    rehabili­tated. During construction, historic furnishings will be
    stored at a suitable facility. After construction is complete, the
    furnishings will be returned to the Superintendent's Residence since
    they are an integral part of the structure's historic integrity.

-   Exterior Treatments -- roof and dormer wood shingles will be
    replaced in-kind; existing non-historic roll-up garage door and
    single-leaf garage door will be replaced with doors that match the
    historic configuration using the historic design drawings as a
    guide; the porch light will be relocated to its historic location;
    false outlookers (false rafter tails) that have fallen off will be
    replaced to match the existing configuration of existing outlookers;
    and a permanent solution for the snow shutters will be designed that
    is functional and in keeping with the historic character of the
    structure.

-   Accessibility For All Populations (Americans with Disabilities Act
    of 1990 (ADA)) -- modifications for accessibility will include
    modification of the back porch for universal access; modification of
    the living room and bathroom on the first floor to create a
    universally accessible bathroom; modifi­cation to the back door and
    openings from the laundry to the master bedroom to create accessible
    routes to all first-floor rooms; an exterior ramp to the back door;
    and an accessible path from the parking area to the back door ramp
    (approximately 180 feet).

-   Public Access -- a short spur trail will be built to connect the
    Superintendent's Residence with the existing Park Headquarters
    Historic Walking Tour loop trail in order to enhance access to the
    building by the general public.

-   Structural Work -- the roof framing will be strengthened. The
    undermined footings in the crawl space will be underpinned. The
    Lateral Force Resisting System (the resistance of the building
    structure to earthquakes) will be strengthened.

-   Building Systems -- the building envelope, heating and ventilation,
    plumbing, and fire protection systems will be rehabilitated or
    replaced. Alternatives to replacement could include new historically
    compatible storm windows that allow operation of the original
    steel-sash windows, installation of an instantaneous water heater,
    and installation of a dry-pipe automatic sprinkler system. A new
    sewerline will also be installed to service the building.

-   Power and Lighting -- new wiring will be run in walls and ceilings
    that are being replaced or repaired for architectural reasons.
    Lighting will be reused and rehabilitated when possible. Power and
    receptacles will be brought up to current safety standards.

-   Landscaping -- using historic photographs and primary drawings,
    original landscaping will be restored. Where plantings are currently
    missing, vegetation matching the historic plant materials will be
    added in the vicinity of the residence.

### Other Alternatives Considered

The no-action alternative, alternative A in the environmental
assessment, would not meet the project objectives of rehabilitating the
Superintendent's Residence. Under the no-action alternative, general
deterioration of the Superintendent's Residence would continue. Limited
maintenance and repairs would be performed to stabilize the structure.
However, the Superintendent's Residence would remain uninhabitable due
to its condition, the structure would continue to degrade without
significant repairs, and the building would remain inaccessible to
disabled persons.

An alternative was considered that would rehabilitate the
Superintendent's Residence as a residential dwelling. Restoration of the
Superintendent's Residence to serve again as a single-family residence
or as a multi-occupancy residence would be more in keeping with the
historic use of the structure. However, past attempts to use the house
as a residence have proven to be impractical or have resulted in
unacceptable impacts to historic fabric and furnishings. For these
reasons, this alternative was considered but rejected from analysis.

### Rationale for the Selected Action

The selected action is considered beneficial for the preservation and
maintenance of the historic fabric and historic characteristics of the
structure. Without the rehabilitation alternative, general maintenance
is not sufficient to bring the structure to current health and safety
standards. As summarized in the following sections, the selected action
(preferred alternative) also best meets the criteria in section 101 of
the National Environmental Policy Act (NEPA) for the environmentally
preferred alternative. Also, after consideration of the effects
described in the environmental assessment, there are no significant
impacts to the human environment from the selected action, as defined by
criteria presented in 40 *Code of Federal Regulations* (CFR) 1508.27.

### Environmentally Preferred Alternative

In accordance with Director's Order -- 12, the National Park Service is
required to identify the environmentally preferred alternative in all
environmental documents, including environ­mental assessments. The
environmentally preferred alternative is determined by applying the
criteria suggested in NEPA, which is guided by the Council on
Environmental Quality. The Council on Environmental Quality provides
direction that "\[t\]he environmentally preferable alternative is the
alternative that would promote the national environmental policy as
expressed in section 101 of NEPA, which considers:

1.  Fulfilling the responsibilities of each generation as trustee of the
    environment for succeeding generations.

2.  Assuring for all generations safe, healthful, productive, and
    aesthetically and culturally pleasing surroundings.

3.  Attaining the widest range of beneficial uses of the environment
    without degradation, risk of health or safety, or other undesirable
    and unintended consequences.

4.  Preserving important historic, cultural, and natural aspects of our
    national heritage and maintain, wherever possible, an environment
    that supports diversity and variety of individual choice.

5.  Achieving a balance between population and resource use that would
    permit high standards of living and a wide sharing of life's
    amenities.

6.  Enhancing the quality of renewable resources and approach the
    maximum attainable recycling of depletable resources."

The environmentally preferred alternative in this environmental
assessment is rehabilitation of the Superintendent's Residence, the
National Park Service preferred alternative. This alterna­tive was
selected as the best value when considering construction costs,
life-cycle costs, and other advantages including:

-   preventing loss of cultural/historic resources (NEPA criteria 1 and
    4)

-   protecting public health, safety, and welfare (NEPA criteria 2 and
    3)

-   improving operations efficiency and sustainability (NEPA criteria 1
    and 6)

-   protecting employee safety and welfare (NEPA criteria 3)

In short, this alternative will minimize disturbance to a known historic
structure and landmark; limit introduction of new human-made features
into the environment; preserve the cultural landscape; provide
protection of public and employee health, safety, and welfare; and
improve day-to-day operations of the facility.

The no-action alternative would allow the Superintendent's Residence to
continue in a state of disrepair and would not adequately preserve this
national historic landmark. The no-action alternative does not meet the
criteria for the environmentally preferred alternative.

## MITIGATION

Throughout our planning process, mitigation measures were identified and
have been incorporated into the selected action (preferred alternative)
to reduce impacts below a significant level. All mitigation measures for
the rehabilitation of the Superintendent's Residence are summarized in

### Why the Selected Action (Preferred Alternative) Would Not Have a Significant Impact on the Human Environment

As defined by 40 CFR 1508.27, significance is determined by examining
the following criteria:

#### Impacts That May Be Both Beneficial and Adverse

Impacts that may have both beneficial and adverse aspects and that may
be beneficial, but may still have significant adverse impacts that
require analysis in an environmental impact statement.

No major adverse or beneficial impacts were identified that would
require analysis in an environmental impact statement. The selected
action (preferred alternative) will have no or negligible impacts on air
quality, archeological resources, concessions operations, ecologically
critical areas, wildlife, threatened and endangered species,
environmental justice, ethnographic and Indian trust resources, land
use, floodplains, geological resources, lightscapes, prime and unique
farmlands, scenic resources, socioeconomics, soundscapes, wetlands, and
water quality.

Short-term, adverse, negligible impacts on health and safety and visitor
use and experience are expected during construction from the selected
action. There will be short-term, minor, adverse impacts on cultural
land­scapes, vegetation, and park operations, and negligible to minor,
adverse impacts to soils. There will be long-term, negligible to minor,
adverse impacts to park operations from maintenance and operations
requirements. There will be long-term, minor, beneficial effects to
cultural landscapes, soils, health and safety, and visitor use and
experience when construction is complete. There will be short-term,
minor to moderate, adverse impacts and long-term, moderate, beneficial
effects to the historic structures from the rehabilitation. Impacts
associated with the selected action (preferred alternative) will be
localized to the site of the historic Superintendent's Residence or the
park.

#### Degree of Effect on Public Health or Safety

Under the selected action (preferred alternative), the Superintendent's
Residence will meet safety standards for electrical, mechanical,
seismic, accessibility, and fire protection, allowing for safe
occupation of the building. Rodent and wildlife infestation will be
abated, reducing safety and health risks to its occupants. Removal of
the oil furnace and tank will reduce risk of contamination to the
environment. The general condition of the structure will be improved.
The selected action (preferred alternative) will result in potential
short-term, negligible impacts to construction workers and long-term,
minor, beneficial impacts to visitor and employee health and safety.

#### Unique Characteristics of the Geographic Area such as Proximity to Historic or Cultural Resources, Park Lands, Prime Farmlands, Wetlands, Wild and Scenic Rivers, or Ecologically Critical Areas

As described in the environmental assessment, ecologically critical
areas, threatened and endangered species, floodplains, prime and unique
farmlands, wetlands, and water quality will not be affected.

There are no known archeological, ethnographic, or Indian trust
resources proximate to the project area; therefore, no impacts to these
resources are anticipated.

The Superintendent's Residence was built in 1932, and completed in 1933.
In 1987, the building was designated a national historic landmark
because it is one of the finest examples of rustic architecture in the
nation. In 1988, the Munson Valley Historic District, which contains the
park headquarters area, including the Superintendent's Residence, was
listed on the National Register of Historic Places (NRHP). The NRHP
nomination designated 18 buildings constructed between 1926 and 1941, in
the rustic style that contribute to the significance of the district. As
a district, these buildings are representative of rustic architecture
built in the national parks during the Hoover Administration and
Roosevelt New Deal programs of the Depression era.

The selected action (preferred alternative) will result in short-term,
minor to moderate, adverse impacts to the historic structure during
construction, but will allow the building to be restored and maintained
as a historic structure. Therefore, the selected action (preferred
alternative) will provide long-term, moderate, beneficial effects for
the national historic landmark. In the short-term, construction
activities, including construction of the ADA-accessible path and
restoration of the historic landscaping, as well as outside work on the
building itself and construction of the sewer line, will result in
minor, adverse impacts to the cultural landscape. The overall impacts to
cultural landscapes will be short term, minor, and adverse and long
term, minor, and beneficial.

After applying the Advisory Council on Historic Preservation's criteria
of adverse effect (36 CFR 800.5), the National Park Service determined
that the activities proposed in alternative B would have *no adverse
effect* to the national historic landmark or the NRHP-listed historic
district. Concurrence with this determination was received from the
Oregon State Historic Preservation Office on January 13, 2004.

#### Degree to Which Effects on the Quality of the Human Environment are Likely to be Highly Controversial

There were no highly controversial effects identified during preparation
of the environmental assessment, agency consultation, or the public
review period.

#### Degree to Which the Possible Effects on the Quality of the Human Environment are Highly Uncertain or Involve Unique or Unknown Risks

There were no highly uncertain, unique, or unknown risks identified
during preparation of the environmental assessment, agency consultation,
or the public review period.

#### Degree to Which the Action May Establish a Precedent for Future Actions with Significant Effects or Represents a Decision in Principle About a Future Consideration

The selected action (preferred alternative) neither establishes a
National Park Service precedent for future actions with significant
effects nor represents a decision in principle about a future
consideration.

#### Whether the Action is Related to Other Actions with Individually Insignificant but Cumulatively Significant Impacts

Impacts to vegetation, soils, cultural landscapes, historic structures,
health and safety, park operations, and visitor use and experience were
analyzed in the environmental consequences section of the environmental
assessment.

As described in the environmental assessment, cumulative impacts were
determined by combining the impacts of the selected action (preferred
alternative) with other past, present, and reasonably foreseeable future
actions. There were no past projects identified during scoping that
would contribute to cumulative impacts. Present and future actions that
may have potential to cumulatively impact resources include:

-   rehabilitation of the historic Naturalist's Residence (building 20)

-   restoration of the Munson Valley Historic District landscaping

-   rehabilitation of the historic warehouse

-   rehabilitation of the historic hospital

-   reconstruction of the Rim parking lot

-   rehabilitation of the Rim cafeteria

-   waterline replacement from Munson Springs to Garfield

-   rehabilitation of the sewage lagoons at Munson Valley

The short-term, negligible to moderate, adverse impacts of the selected
action (preferred alternative), combined with impacts of past, present,
and reasonably foreseeable actions, could result in short-term,
negligible to moderate, adverse, cumulative impacts to vegetation,
soils, cultural landscapes, historic properties, health and safety, park
operations, and visitor use and experience.

The long-term, negligible to moderate, beneficial effects of the
selected action (preferred alternative), combined with impacts of past,
present, and reasonably foreseeable actions, could result in long-term,
negligible to moderate, beneficial, cumulative effects on vegetation,
soils, cultural landscapes, historic properties, health and safety, park
operations, and visitor use and experience.

#### Degree to Which the Action May Adversely Affect an Endangered or Threatened Species or Its Critical Habitat

The rehabilitation of the Superintendent's Residence will not affect
endangered or threatened species or critical habitat potentially
occurring in or near the project area. Consultation with the U.S. Fish
and Wildlife Service was completed and led to the same finding.

#### Whether the Action Threatens a Violation of Federal, State, or Local Environmental Protection Law

The selected action (preferred alternative) violates no federal, state,
or local environmental protection laws.

## Impairment of Park Resources or Values

In addition to reviewing the list of significance criteria, Crater Lake
National Park determined that implementation of the selected action
(preferred alternative) will not constitute an impairment of park
resources or values. This conclusion is based on a thorough analysis of
the impacts described in the environmental assessment, the lack of
agency and public comments received, and the professional judgment of
the decision-maker in accordance with the *NPS Management Policies 2001*
(December 27, 2000). As described in the environmental assessment,
implementation of the selected action (preferred alternative) will not
result in major adverse impacts to a resource or value whose
conservation is (1) necessary to fulfill specific purposes identified in
the establishing legislation or proclamation of Crater Lake National
Park; (2) key to the natural or cultural integrity of the park; or (3)
identified as a goal in the park's *General Management Plan* or other
relevant National Park Service planning documents.

## Public Involvement and Agency Consultation

The environmental assessment was made available for public review and
comment during a 30-day period ending December 24, 2003. Copies of the
environmental assessment were made available at the park. Approximately
16 environmental assessments were distributed during the comment period.
An electronic copy of the environmental assessment was also placed on
the park's Web site. No comments were received during this 30-day public
review and comment period.

Compliance with section 106 of the National Historic Preservation Act
was completed through consultation with the Oregon State Historic
Preservation Office. Consultation began in July of 2001. Oregon State
Historic Preservation Office specialists conducted three site visits in
2001, 2002, and 2003. In November of 2003, transmittal of the
environmental assessment to the State Historic Preser­vation Office
occurred. The State Historic Preser­vation Office determined that the
selected action (preferred alternative) would have *no adverse effect*
on identified historic resources (letter from James M. Hamrick Jr.,
Oregon Parks and Recreation Department, State Historic Preservation
Office, January 13, 2004).

Compliance with section 7(c) of the Endangered Species Act of 1973, as
amended, was completed through consultation with the U.S. Fish and
Wildlife Service. The U.S. Fish and Wildlife Service sent a letter of
concurrence on the determination that the project will have no effect on
federally listed endangered or threatened species, dated December 16,
2003.

## CONCLUSION

The selected action (preferred alternative) does not constitute an
action that normally requires preparation of an environmental impact
statement. The selected action (preferred alternative) will not have a
significant effect on the human environment. Negative environmental
impacts that could occur are considered short term and negligible to
moderate in intensity. Mitigation measures are incorporated into the
selected action (preferred alternative) to avoid, reduce, or eliminate
impacts. A letter of concurrence on the determination of no effect on
federally listed endangered or threatened species was received from the
U.S. Fish and Wildlife Service. There are no foreseen significant
adverse impacts on public health, public safety, threatened or
endangered species, historic properties either listed in or eligible for
listing in the NRHP, or other unique characteristics of the park. Nearby
wetlands will be delineated and avoided. No highly uncertain or
controversial impacts, unique or unknown risks, significant cumulative
effects, significant effects from connected actions, or elements of
precedence were identified. Implementation of the action will not
violate any federal, state, or local environmental protection law, nor
will it cause impairment of park resources or values.
