Attachment A – Historic Snapshot: N101 & N201

Buildings N101 and N201 are contributing resources in the Nisqually Entrance Historic District, listed on the National Register of Historic Places in 1991 (NRHP Ref. No.

91000172).

• N101, constructed in 1915, served as the Superintendent’s residence and reflects early administrative planning in the park.

• N201, built in 1934 by the Civilian Works Administration, remains in its original use as a six-bay utility and equipment garage.

Both structures retain defining characteristics of the National Park Service Rustic architectural style including wood siding, gabled cedar-shingle roofs, and minimal ornamentation. They exemplify the park’s 20th-century development and operational continuity.

These buildings not only remain structurally intact, but their continued use in support of park operations further demonstrates the relevance of their original design. This attachment validates the need for preservation-sensitive door replacements that ensure operational continuity while respecting architectural legacy. The historical integrity and location within the historic district underscore the necessity for a carefully scoped project compliant with federal preservation guidelines.

Attachment B – Photo Documentation Log

A comprehensive set of photos documents:

• Exterior and interior views of all garage bays

• Condition of existing door panels, tracks, locking hardware

• Environmental impacts such as water intrusion, moss, and wear patterns

• Surrounding structural context including vegetation, access roads, and siding

The photographs reinforce the project’s necessity. Visual records show wear from decades of use, deferred maintenance, and environmental exposure common in high-elevation, high-moisture locations. Damage to lock systems and weathered panel materials highlight vulnerability to theft, wildlife intrusion, and material degradation—all of which compromise secure storage for park vehicles and tools essential to ranger and maintenance duties.

Attachment C – NRHP Form (Nisqually Entrance District)

The NRHP nomination form outlines the historic context, construction history, and architectural integrity of both N101 and N201.

It substantiates their inclusion as contributing structures and confirms their preservation significance under:

• Criterion A – early park administration and federal development

• Criterion C – Rustic style architecture employing local materials

The nomination documentation describes how park structures were intended to harmonize with the surrounding environment and provide minimal visual disruption. This foundation mandates that any intervention—such as garage door replacement—uphold those design principles. Reference to this form substantiates the design approach selected for this SOW and confirms compliance with preservation responsibilities.

Justification: This form serves as the federal basis for Section 106 review and treatment scope.

While it does not contain prescriptive work details, it provides the official framework for evaluating the appropriateness of all proposed modifications.

Attachment D – NRO Inventory Forms

The NPS Cultural Resources Division inventory forms offer detailed architectural descriptions, historic background, materials analysis, and modifications to both structures.

• N101: This 1½-story residence, built in 1915, features a steeply pitched gabled roof with cedar shingles, overhanging eaves, and a large front veranda originally supported by whole log columns. Though modest in size, its log-framed structure and thoughtful craftsmanship reflect the early philosophy of harmonizing architecture with the natural setting. With cedar siding stained in deep brown and a floor plan that once housed the superintendent and his family, the building still communicates its original role as a year-round operational hub.

• N201: Constructed in 1934 by the Civilian Works Administration, this elongated, low-profile garage served as a utilitarian core of ranger and maintenance operations.

Its six wood-clad overhead doors open into individual bays, framed by rough-sawn siding and a saltbox-style gable roof. While simple in form, the structure is visually unified with the park’s rustic design palette and has remained nearly unchanged in plan and appearance since its inception.

Code Reference: NPS Cultural Resource Management Guidelines (DO-28), FMSS documentation standards, and SOI Standards for evaluating alterations.

Justification: Inventory records establish physical parameters for what constitutes contributing features, guiding the limits of scope work such as door replacement.

These detailed architectural profiles support decisions on materials, finish, and installation approaches that preserve historic integrity.

Attachment E – Lock Evaluation & Security Notes

Current locks are weathered, misaligned, or no longer functional. Several garage bays have no lockable features, presenting vulnerabilities to unauthorized entry, wildlife access, and equipment loss.

Recommendations:

• Install new commercial-grade matching keyed entry locks rated for exterior security

• Locks to comply with NPS Facility Security Guidelines and FMSS records

• Ensure locks align with ADA and egress codes per NFPA 101 Life Safety Code

Code Reference: NFPA 101, NPS Risk Management Program Manual, DOI Access Control Standards

Justification: Modernized locks increase security without harming historic material. All installations shall be surface-mounted and reversible.

Attachment F – Site Map: Nisqually Housing Area

This site plan shows:

• Proximity of N101 and N201 to roadways, residential areas, and support facilities

• Staging constraints due to one-lane roads and vegetation buffers

• Limits on vehicle turnaround and delivery truck access

Code Reference: NPS Transportation Planning Manual, OSHA 1926.21 site safety and access control

Justification: A clearly defined site map ensures contractor access routes are environmentally sensitive and safety-compliant. It supports pre-mobilization planning and avoids disruption to nearby housing operations.
