In support of permitting for the projects, FWC contracted with Cardno to complete a reconnaissance -level survey of the entire former campus. The reconnaissance -level survey evaluated the historical significance of the property. Purpose of the Work: This reconnaissance -level survey was conducted to satisfy regulatory requirements for obtaining a Joint Aquatic Resources Permit Application (JARPA) from the U.S. Army Corps of Engineers (USAGE). As part of the federal review process, the USACE is required to comply with Section 106 of the National Historic Preservation Act (NHPA; 16 U.S. Code 470) and its implementing regulations (36 Code of Federal Regulations [CFR] Part 800). Section 106 requires federal agencies to take into account the effects of their undertakings on historic properties, which is either listed in or eligible for listing in the National Register of Historic Places (NRHP). The survey was designed to identify built environment resources within the entire former campus, and to provide recommendations to FWC and the USACE concerning the eligibility of these resources for the NRHP. The existing headquarters building was preliminarily determined eligible for listing in the NRHP in 2017; however, none of the other historic resources within the former campus were previously evaluated. Dates of Survey: Multiple days between February 13 and June 7, 2019 Cultural Resources Recommended NRHP Eligible: One historic district (cultural landscape), three buildings (Project House 1, Project House 2, and King County Fire District No. 22 Fire Station) Cultural Resources Recommended Not NRHP Eligible: One building (Former Puget Sound Power & Light Company Service Building) Summary and Recommendations: Following the completion of a built environment survey of the former Weyerhaeuser Corporate Headquarters campus, Cardno recommends that the historic designed landscape is eligible for the NRHP as a historic district at a national level of significance. The recommended -eligible historic district possesses integrity of location, setting, design, materials, workmanship, feeling, and association. Cardno recommends that the proposed historic district meets NRHP Criteria A and C for its associations with the introduction of the suburban corporate campus to the West Coast, its association with Weyerhaeuser Company's changing corporate image, and as an outstanding example of the integrated work of architect Edward Charles "Chuck" Bassett of Skidmore, Owings, and Merrill and Peter Walker of Sasaki, Walker and Associates. Because of the proposed historic district's exceptional historical and design significance, it is recommended eligible at a national level of significance under Criteria Consideration G for resources that have achieved significance within the past 50 years. Its recommended period of significance is 1969 — 1979. In addition, three historic properties are recommended eligible for individual listing in the NRHP at a local level of significance: Project House 1, Project House 2, and the King County Fire District No. 22 Fire Station. Evaluation of potential project effects from FWC's proposed projects will be provided in forthcoming reports. July 2020 Cardno Executive Summary i Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 1 Introduction This technical report presents the results of a reconnaissance -level built environment survey conducted of the former Weyerhaeuser Corporate Headquarters campus in Federal Way, Washington, on behalf of Federal Way Campus, LLC (FWC) (Figure 1 and Figure 2). This survey is intended to provide technical documentation to supplement FWC's Joint Aquatic Resource Permit Applications (JARPA) that will be submitted to the U.S. Army Corps of Engineers (USACE). The analysis in this report relates only to the federal undertaking as reviewed under Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended as amended (NHPA; 16 U.S. Code 470), and its implementing regulations (36 Code of Federal Regulations [CFR] Part 800) (Section 106). The survey and analysis were completed by a Cardno architectural historian who meets the U.S. Secretary of the Interior's Professional Qualifications Standards for architectural history and history (36 CFR Part 61). 1.1 Project Location The project area encompasses approximately 490 acres in Federal Way, King County, Washington. It is bounded at the north by South 320th Street, at the east by parcel lines east of Weyerhaeuser Way South and North Lake and then south via Weyerhaeuser Way south to State Route 18, at the south by State Route 18, and at the West by Interstate 5.

The following discussion briefly describes the federal laws and regulations that govern the cultural resources review process for these projects. The Washington State Environmental Policy Act (SEPA) (Revised Code of Washington 43.21 C) and implementing rules contained in Washington Administrative Code 197-11, require consideration be given to significant historic, archeological, and traditional cultural sites. Additionally, some local governments, such as the City of Federal Way, also have ordinances to protect significant historic resources; however, local jurisdictions have different implementing standards than Section 106 of the NHPA. This report addresses Section 106 and is not intended to address SEPA. 2.1 National Historic Preservation Act Section 106 of the NHPA requires that the lead federal agency with jurisdiction over a federal undertaking (i.e., a project, activity, or program that is funded by a federal agency or that requires a federal permit, license, or approval) consider the potential for project effects to historic properties listed in or eligible for the NRHP before that undertaking occurs. In addition, the federal agency —in this case, the USACE— must consult with the State Historic Preservation Officer (SHPO), federally recognized Indian tribes, applicants for federal assistance, local governments, and any other interested parties regarding the proposed undertaking and its potential effects on historic properties. The goal of consultation is to identify historic properties potentially affected by an undertaking, assess the undertaking's effects, and seek ways to avoid, minimize, or mitigate any adverse effects on historic properties. 2.1.1 Determining the Area of Potential Effects under Section 106 of the NHPA In compliance with the NHPA, this study evaluates the NRHP eligibility of resources that are at least 50 years of age and are located within the Area of Potential Effects (APE), which is the "geographic area or areas within which [the] undertaking may directly or indirectly cause alterations in the character or use of historic properties, if any such properties exist" (36 CFR § 800.16 (d)). This study identifies issues relating to the proposed developments' potential effects on cultural resources in the APE. Cardno has developed a proposed APE based on the proposed development projects' scope and the potential boundary for the existing features of the historic Weyerhaeuser Corporate Headquarters campus. However, the USACE will review and determine the APE. 2.1.2 Evaluation of Historic Properties under Section 106 of the NHPA The NRHP, created under the NHPA, is the federal list of historical, archaeological, and cultural resources worthy of preservation. Resources listed in the NRHP include districts, sites, landscapes, buildings, structures, and objects that are significant in American history, prehistory, architecture, archaeology, engineering, and culture and that possess integrity of location, design, setting, material, workmanship, feeling, and association. Section 106 defines "historic property" as "any prehistoric or historic district, site, building, structure, or object included in, or eligible for inclusion in, the NRHP" (36 CFR § 800.16 (1)(1)). The NRHP is maintained by the National Park Service (NPS) on behalf of the U.S. Secretary of the Interior. The Washington State Department of Archaeology and Historic Preservation (DAHP) administers the statewide NRHP program under the direction of the Washington SHPO, located in Olympia, Washington. The NPS has developed NRHP Criteria for Evaluation to guide the evaluation of cultural resources that may be either listed in or eligible for the NRHP. Section 106 requires the determination of eligibility for the NRHP as a tool for identifying significant historic properties. If a property is determined eligible for the July 2020 Cardno Regulatory Background 2-1 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus NRHP under the Section 106 process, it does not automatically result in the listing of the property in the NRHP. As described in the NPS's National Register Bulletin (NRB) 15 "How to Apply the National Register Criteria for Evaluation," the four criteria used to determine eligibility are that the property: > Criterion A: Is associated with events that have made a significant contribute to the broad patterns of our history; or > Criterion B: Is associated with the lives of persons significant in our past; or > Criterion C: Embodies the distinctive characteristics of a type, period, or method of construction or represents the work of a master, or possesses high artistic values, or represents a significant and distinguishable entity whose components may lack individual distinction; or > Criterion D: Has yielded, or may be likely to yield, information important in prehistory or history (36 CFR Part 60). In addition to these criteria, for a property to be determined eligible for the NRHP, it must continue to possess sufficient physical characteristics that reflect that historical significance, defined as "integrity." The facets of integrity evaluated under the NRHP are integrity of: > Location > Design > Setting > Materials > Workmanship > Feeling > Association Finally, while ordinarily a historic property should be 50 years old or older to be considered eligible for the NRHP, there is an additional Criteria Consideration that provides for the ability of a property that achieved significance more recently than 50 years ago to be considered for eligibility for or designation in the NRHP provided it is "of exceptional importance" (Criteria Consideration G). In addition to NRB 15, other formal guidelines appropriate for the evaluation of a historic property include: > NRB 16a, "How to Complete the National Register Registration Form," which outlines the distinction between contributing and non-contributing properties in historic districts; > NRB 21 and 12, "Defining Boundaries for National Register Properties," which presents guidelines for determining what to include and exclude from the boundaries of historic properties, including historic districts; > NRB 22, "How to Evaluate and Nominate Potential National Register Properties That Have Achieved Significance Within the Last 50 Years," which provides guidance on making determinations of eligibility under Criteria Consideration G (36 CFR Part 60); > NRB 18, "How to Evaluate and Nominate Designed Historic Landscapes," which addresses special factors for determining significance of landscapes; and > Preservation Brief 36, "Protecting Cultural Landscapes: Planning, Treatment and Management of Historic Landscapes," by landscape architect Charles A. Birnbaum, which provides further guidance on unique issues affecting cultural landscapes. Other references consulted during the course of the project are cited in the bibliography in Section 7. 2-2 Regulatory Background Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 3 Project Methodology Cardno conducted a reconnaissance -level survey between February and June 2019. Michelle Sadlier, MA, served as Lead Architectural Historian. Ms. Sadlier meets the U.S. Secretary of the Interior's Professional Qualifications Standards for architectural history and history (36 CFR Part 61). Registered landscape architect Becky Strickler and geographic information system specialist Kevin Gabel provided relevant technical services. Cardno's Pacific Northwest Cultural Resources Practice Group Leader, Jennifer Ferris, MA, was the project manager and provided quality assurance/quality control review with support from Malini Roberts, Technical Editor. Ms. Sadlier conducted multiple site visits to the land represented in the 1969 plans as owned by Weyerhaeuser Company at that time for the purposes of building a headquarters building and other potential future development (Figure 2). Survey methods followed guidelines by the Washington State SHPO and DAHP for Section 106 review, namely that "reconnaissance surveys consist of walking around an area and noting the general distribution of buildings, structures, and neighborhoods representing different architectural styles, periods, and modes of construction" (DAHP 2020). Ms. Strickler and Ms. Ferris each accompanied Ms. Sadlier on one site visit to offer additional insight into the potential historical significance of the campus and its component features. A thorough photographic record was gathered over the course of field survey. Because the property is a campus that is a collection of buildings and landscape features created by a team of architects and landscape architects, Cardno has evaluated it as a designed historic landscape, a type of cultural landscape described by the NPS as follows: A landscape that has significance as a design or work of art; was consciously designed and laid out by a master gardener, landscape architect, architect, or horticultural ist to a design principle, or an owner or another amateur using a recognized style or tradition in response or reaction to a recognized style or tradition; has a historical association with a significant person, trend, event, etc. in landscape gardening or landscape architecture; or a significant relationship to the theory of practice of landscape architecture. (Keller and Keller n.d:1) Cardno further refined this definition under guidance provided by Arnold R. Alanen and Robert Z. Melnick to include the evaluation of topography, vegetation, water features, objects, and site furnishings, not to mention the buildings themselves (Alanen and Melnick 2000:1-2). NRB 18, "How to Evaluate and Nominate Designed Historic Landscapes" guided the analysis and recommendations provided in this report (Keller and Keller n.d.). In addition to visual inspection during site visits, the project team evaluated the historic property using a variety of different resources. These included online databases as well as archival and other records accessed in -person at: > Weyerhaeuser Technology Center (WTC), Federal Way, Washington, where Weyerhaeuser Corporation records approved for viewing were provided by Andy Bylin; > Carl A. Weyerhaeuser Library, Forest History Society, Durham, North Carolina; > Puget Sound Branch of the Washington State Archives, Bellevue, Washington; and > King County Archives, Seattle, Washington. Given the relatively recent age of the historic property, attempts were made to interview any living members of the design team responsible for the development and execution of the campus plan. Two members of this team were known to be living at the time of this survey. A telephone interview was held July 2020 Cardno Project Methodology 3-1 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus on May 22, 2019, with Peter Walker, formerly of Sasaki, Walker and Associates (SWA), who was partner - in -charge of the development of the campus site plan and landscape features. The other living member of the original team who developed the plans was George Weyerhaeuser. While efforts were made to reach Mr. Weyerhaeuser, he was unavailable for interview during the course of this study. To gain further insights into the significance of the campus as well as its inspiration and later influence on the design field, oral interviews were conducted with the following University of Washington College of Built Environment faculty members: > Meredith Clausen, Professor of Art and Architectural History (May 1, 2019); > Brian McLaren, Associate Professor of Architecture and Chair of the Department of Architecture (April 24, 2019); > Jeffrey Ochsner, Professor of Architecture (May 8, 2019); > David Streatfield, Emeritus Professor of Landscape Architecture (May 24, 2019); and > Thaisa Way, Professor of Landscape Architecture (May 8, 2019). Technical guidance was also provided by Charles A. Birnbaum of the Cultural Landscape Foundation (TCLF) and Michael Houser and Holly Borth of the Washington DAHP. Cardno held two information - gathering meetings with Ms. Borth and Mr. Houser: one via video conference on April 10, 2020 and another on site on June 24, 2020. 3-2 Project Methodology Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 4 Historical Context for the Weyerhaeuser Campus 4.1 Weyerhaeuser: A Brief Overview of the Corporation Today, Weyerhaeuser Company is a corporation that owns over 12 million acres of timberland in the United States alone. Nearly three million of those acres are found in the Pacific Northwest states of Washington and Oregon (Weyerhaeuser Company 2018). This makes the company the top-ranking timberland owner in the country, with Rayonier a distant second place at just over two million (Statista 2018). According to a 2018 annual report, the company operates 35 mills nationwide, producing lumber, oriented strand board, plywood, and other construction -related wood products. Five of these mills are located in the Pacific Northwest. The corporation has its origins at the turn of the nineteenth century, when it was founded by German-born Frederick Weyerhaeuser (1834-1914) (Figure 4). Weyerhaeuser emigrated to the United States in the 1850s, eventually finding his way to Rock Island, Illinois, where he started working in the lumber industry. During his decades in the Midwest, he gradually worked his way up in the production side of the industry, and then began buying interest in a number of mills. His move to St. Paul, Minnesota, in the 1890s heralded the start of a friendship with the majority owner of the Northern Pacific Railway, James J. Hill (1838-1916). In 1900, Weyerhaeuser Timber Company was formed when Hill sold 900,000 acres of land in Washington State to Frederick Weyerhaeuser and 11 investors. Initially, management of the company remained with Frederick Weyerhaeuser in St. Paul (Warren 1999). Figure 4. Frederick Weyerhaeuser (left), founder of the company, and George H. Weyerhaeuser, president during the development and execution of plans for the new corporate headquarters in Federal Way, Washington. (Images courtesy of the Weyerhaeuser Company) The purchase of land and sale of standing timber to mill owners was the focus of the company's business in the early years. Weyerhaeuser Timber Company's first facility, however, was the first sawmill in July 2020 Cardno Historical Context for the Weyerhaeuser Campus 4-1 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Everett, constructed in 1903. Business expansion during World War I was fueled by high demand for lumber for ships, airplanes, and barracks. Following the opening of a second mill in Everett in 1915, 20 other new mills were opened around the country in quick succession (Warren 1999). The company continued to expand and diversify during the interwar years, developing new products for insulation, establishing a grade -marked lumber program ("4-Square Lumber"), and entering the steamship business in the 1920s. The new sawmill in Longview, Washington, went into the pulping business in the 1930s (Figure 5). Later that decade, sustainable forestry experiments took shape. Weyerhaeuser Timber Company opened the first tree farm in the country in Montesano, Washington, in 1941 (Weyerhaeuser Company 2019a). � anew Pvly 1ilv�it not urRv r1�i WE loaded : -' Lewiston -.

(Image courtesy of Weyerhaeuser Forest Products 1937) Technological innovation needed to meet the demands of providing raw materials for World War II led to a major expansion of forest products in the decade following the end of the war. Plywood, veneer, particleboard, and containerboard, as well as other wood -fiber products, were produced by Weyerhaeuser Timber Company during this period. In the 1950s, the company expanded in the Southern U.S. as well as overseas. With such a diversity of products, the company decided to drop reference to "timber" and changed its name to Weyerhaeuser Company in 1959, at which time it adopted the logo still used today. From this point until the decision to develop a new headquarters in the mid-1960s, the company moved into the fine paper market, began producing paneling and architectural doors, and harvested its first sustainably produced timber (Weyerhaeuser Company 2019a). Prior to the decision to centralize its headquarters and research facilities in Federal Way, Weyerhaeuser Company's corporate managerial geography was scattered between a centralized urban headquarters and multiple manufacturing centers across North America. These included Northwestern industrial and research centers in Everett, Longview, and Snoqualmie Falls in Washington State, Klamath Falls in Oregon, and Coeur d'Alene and Lewiston in Idaho, and the company's main headquarters in the Tacoma 4-2 Historical Context for the Weyerhaeuser Campus Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Building in Tacoma, Washington (Weyerhaeuser Forest Products 1937). As Weyerhaeuser Company grew, the 10-story Tacoma Building was substantially expanded with a new 12-story wing in 1957 (Figure 6 and Figure 7). By the time a new headquarters building was being conceived, company staff were housed in 20 different buildings in downtown Tacoma. As a result, in 1965, less than 10 years after the expansion of the Tacoma Building, the company began seriously investigating ideas to combine all its Tacoma offices onto one site and commissioned a study of other national examples of contemporary corporate headquarters in 1965 (Forest History Society 2019).

Weyerhaeuser Library, Forest History Society, Durham, North Carolina) The context of the Weyerhaeuser Company story at the time the corporate headquarters facility was designed would be incomplete without a brief introduction to George H. Weyerhaeuser (born 1926) (Figure 4). George Weyerhaeuser's tenure as president of the company (1966-1991) was remarkable due to its length and because he was the last Weyerhaeuser to hold this position. As a great-grandson of founder Frederick Weyerhaeuser, George Weyerhaeuser represented a new generation in leadership. His predecessor, Norton Clapp, had been the first president who was not a member of the Weyerhaeuser family, but George Weyerhaeuser was the first of his generation of Weyerhaeusers to assume the role (Weyerhaeuser Company 2019a). Additionally, he was only 40 years old when he became company president, young by comparison with his predecessors. Under George Weyerhaeuser's leadership, the Weyerhaeuser Company's projected image made a subtle but fundamental shift. Through the 1960s, much of the company's marketing focused on demonstrating its growth and use of trees as a commodity converted into products (Seattle Times 1965:64) (Figure 8). By the 1970s, the message shifted to Weyerhaeuser as a practitioner of forest management under the motto, "The Tree Growing Company" (Seattle Times 1977:D2) (Figure 9). The new corporate headquarters played a role in expressing the image change Weyerhaeuser Company projected from the 1970s onward. According to design -team member Peter Walker, George Weyerhaeuser's youthful creativity and passion played a pivotal role in the successful design and realization of the new corporate campus (P. Walker, personal communication, May 22, 2019). 4-4 Historical Context for the Weyerhaeuser Campus Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Some people All - think our business is tree (that's only half the story) Ask almost anybody what Weyerhaeuser does and he's apt to tell you we grow trees for lumber.

Writing during what is arguably the heyday of the Modern Movement in the U.S., Saylor defines Modernism as, "a school of thought in design which stresses contemporary needs and technics as against following forms of the past" (1952:114). More recently, Fleming, Honour, and Pevsner add more flesh to the bones provided by Saylor, defining the movement as a "term for twentieth-century avant- garde movements in architecture which shared a concern for functionalism and new technology, a rejection of ornament, and aspired to create new solutions for architecture and urban design appropriate to the social conditions of the twentieth century" (1999:384). Part of a wider intellectual movement, it is often perceived as a twentieth-century break with the past, yet its genesis dates to the nineteenth century. Architect and restorer Eugene Emmanuel Viollet-le-Duc's (1814-1879) observation on the need for all elements of architecture to have a structural function may have been an early precursor to the central tenets of the Modernist movement. The integral links between engineering and architecture that would later be hallmarks of the movement can be seen in such Victorian masterpieces as London's Crystal Palace (1851) and the Eiffel Tower (1889) (Peter 1958:14-15). Peter credits skyscraper pioneer Henry Louis Sullivan (1856-1924) with coming up with the phrase that would exemplify the spirit of Modernist architecture: "form follows function" (Peter 1958:19). Influential early practitioners of Modernist design and thinking include the Swiss French designer Charles-Edouard Jeanneret, also known as "Le Corbusier" (1887-1965), and American architect Frank Lloyd Wright (1867-1959), whose sense of space and rejection of Victorian -era nostalgia for the aesthetics of the past helped forge the path to site -level approaches of Modernist design (Peter 1958:21). Modernism in landscape architecture also represented a change in thinking. Walker and Simo observe that the Modernist movement only began to emerge in landscape architecture in the 1930s (1996:3). The authors look back to the long and influential career of Frederick Law Olmsted (1822-1903) as a spring- board to their analysis of Modernism in the field. Along with an aesthetic rooted in romanticism, Olmsted saw the work of the landscape architect as "creating tranquil landscapes in the public domain, where people of diverse backgrounds could relax, intermingle, and develop a sense of community and cooperation" (Walker and Simo 1996:11). Olmsted was viewed as a social improver, and in that way he may be thought to share the sensibilities of the Modern Movement. His work as an artist, however, was rooted in historical romanticism and the picturesque. Another influential thinker of the late nineteenth century who tied social improvement with the landscape was Englishman Ebenezer Howard (1850-1928), who pioneered the concept of the "garden city" in 1898 (Figure 10). Rather than bringing nature to the city to benefit the public, however, Howard's new "town - country" concept was neither truly urban nor truly rural. These garden cities would encompass home, work, and leisure in one community (Howard 1996:322-329). Howard's garden cities were influential in the U.S., albeit as picturesque designs like the 1909 Forest Hills Gardens in Queens, New York, designed by Frederick Law Olmsted, Jr. Forest Hills was designed to be "a cozy domestic landscape built according to the latest 'scientific principles' of town planning," architecturally integrated for a community of middle- class homeowners (Rogers 2001:417). This was early in the transition to widespread suburbanization that followed World War II.

(Howard 1996:324) 4.2.2 Corporate Headquarters: Move to Suburbia In her seminal work on suburban corporate campuses, Mozingo (2011) observes that, prior to the post- war period, most corporation headquarters were either located in downtown commercial centers, within manufacturing plants themselves, or, like Weyerhaeuser, both (Mozingo 2011: 19). The relocation of factories to suburban and rural areas had already gained traction in the earlier part of the twentieth century in part due to the density and challenges of acquiring land in urban cores. The relocation trend also resulted from an increase in "welfare capitalism," which emphasized, among other things, the positive influence of the landscape on the productive blue-collar worker in an era where downtown cores were perceived as having widespread social problems. When corporations began to develop headquarters in new suburban locations in the 1950s, the layout, siting, and design of early suburban factories heavily influenced the features and siting of these new centers of white-collar activity under similar influences (Mozingo 2011: 28-31). 4-8 Historical Context for the Weyerhaeuser Campus Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus In pursuing a suburban campus location, the Weyerhaeuser Company was following in a new tradition set by other corporations in the Midwest and on the East Coast. The project that is generally considered the pioneer suburban corporate campus is that of Connecticut General Life Insurance Company (now CIGNA), completed in 1956 in Bloomfield, Connecticut, on the outskirts of Hartford (Figure 11). The campus was designed by architects Gordon Bunshaft and William S. Brown and landscape architect Joanna Diman of Skidmore, Owings, and Merrill (SOM), the firm that would later design the Weyerhaeuser campus. Frazar B. Wilde, the president of Connecticut General Life Insurance Company, was apparently not a fan of Modernism but, ...he was convinced as a 'good insurance man' that the high modernist design, indeed a sophisticated abstraction of the industrial factory, would deliver 'flexibility, high-grade materials for low maintenance, and qualities of beauty and humanity that would attract and hold clerical employees (mostly young women) in labor short Hartford.' At the same time, Wilde was a famed hiker of New England wildlands and 'an ardent naturalist' who wanted to 'prevent the destruction of wildlife cover on the Bloomfield site (Mozingo 2011:113). Figure 11. An outdoor space for staff relaxation at the Connecticut General Life Insurance Company's headquarters. (Image courtesy of SOM) Concerned that the move from central Hartford to a more rural site might lose employees, Wilde worked with SOM to design a headquarters that would include a range of amenities on -site, such as a cafeteria, game rooms including a bowling alley, a barber shop and beauty parlor, an auditorium, a variety store, and a lending library. As Mozingo notes, "Like the welfare capitalist factories from earlier in the century, the corporation provided an astounding scope of amenities to its employees, in many ways creating an all-inclusive environment, with the services of the city in an ideal rural setting" (Mozingo 2011:113). Soon after the completion of Connecticut General Life Insurance Company's headquarters, many other suburban campuses followed, including the Reynolds Metal Company outside Richmond, Virginia (1957; SOM, with landscape architect Charles Gillette), Upjohn Corporation in Kalamazoo, Michigan (1961; SOM, with landscape architects SWA), and Deere & Company in Moline, Illinois (1964; Eero Saarinen, with landscape architect Hideo Sasaki) (Figure 12).

Site plan of Deere & Company's Moline, Illinois, campus, designed by Eero Saarinen and Hideo Sasaki. Some of the elements that would later characterize the site of the Weyerhaeuser campus are in evidence, including the axial planning in relation to the retention pond and the circulation drive, both of which influence the experience of the integration of the natural and built environment. (Mozingo 2011:125) Weyerhaeuser Company's headquarters in Federal Way was the first notable suburban campus developed on the West Coast (Mozingo 2011:140). This project's pedigree relates directly to these earlier Eastern and Midwestern counterparts. Edward Charles Bassett of SOM, credited with leading the design of the site, worked previously with Eero Saarinen. Additionally, SWA, the landscape architecture firm that developed the remarkable site planning and planting schemes of the Weyerhaeuser corporate headquarters campus, was also involved in a number of these significant early campuses. Indeed, the importance of landscape architects' influence on site planning is critical to the ethos and on -the -ground appeal of the suburban corporate campus. 4-10 Historical Context for the Weyerhaeuser Campus Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 4.3 The Designers 4.3.1 Skidmore, Owings, and Merrill (SOM) The firm of SOM was formed in 1939, when John Ogden Merrill (1896-1975) joined the partnership formed by Louis Skidmore, Sr. (1897-1962) and Nathaniel A. Owings (1903-1984) earlier in the decade (Woodward 1970:11). From its beginnings, SOM's calling card was monumental -scale design. Formed during the early years of World War Il, one of the firm's first major projects was the design of Atomic City (1942-1946), a new town built to support the Manhattan project, in Oak Ridge, Tennessee. The reputation of the firm led to significant —now iconic —commissions that included: > Lake Meadows tower block for the Chicago Land Commission, Chicago, Illinois (1950-1960); > Lever House, New York, New York (1952); > Manufacturers Trust Company Building, New York, New York (1954); > Inland Steel Building, Chicago, Illinois (1957); and > Connecticut General Life Insurance, Bloomfield (Hartford), Connecticut (1957). Using Lever House as his lens (Figure 13), Christopher Woodward describes the SOM partnership's innovative work during this period: More important than its power to startle .... the design of Lever House brilliantly gathered together in one building strands of a large number of contradictory European myths and programmatic requirements of Modern Architecture as set out by Johnson and Hitchcock in The International Style, and the twin American traditions of careful re -use of European forms, and the glamor of display: styling. The building serves as a checklist of those qualities which Hitchcock and Johnson were rash enough to identify in 1932 as qualifying a building for inclusion in the International Style canon: `a new conception of architecture as volume rather than mass'; `regularity rather than axial symmetry serves as the chief means of ordering design'; and the proscription of `arbitrary applied decoration' (Woodward 1970: 12). Woodward also credits Lever House for heralding the return of the public plaza that was to typify urban corporate design during the Modernist era.

SOM's Lever House in New York City. Attributed to William S. Brown, partner in charge, and Gordon Bunshaft, partner in charge of design. (Peter 1958:182) 4-12 Historical Context for the Weyerhaeuser Campus Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Writing over a decade later, Albert Bush -Brown (1983) looks to the transition from SOM's "technological symbolism" work of the 1950s to that completed in the 1970s: In comparison with New York's Lever House or Chicago's Inland Steel of the 1950s, SOM's new buildings often resolve complexities imposed by irregular sites, mixed functions, and struggles to supply maximum rentable space at least cost. The resulting forms depart from the earlier technological imagery. For more than two decades, Lever House and Inland Steel had inspired the architectural profession. Lever House and Inland Steel confined narrow sunlighted slabs to the edges of their sites and offered air space, sidewalk plazas and glazed lobbies. Today their elegance looks innocent: naive about those expediencies prompted by borrowed dollars and rental occupancies, modest in height and land coverage, indifferent about garages or concessionary services, cavalier about historic context, and almost oblivious to energy conservation. (Bush -Brown 1983:11) By the advent of the 1970s, SOM architects had turned away from Lever House or Inland Steel for their inspiration. Bush -Brown observes that their resulting work in the early 1970s "relies on faceted mass, rhythms, texture and color, without exaggerating structural systems to gain formal impact" (Bush -Brown 1983:11). The integration of circulation and public space with the buildings themselves also became more central to the design. Overall, SOM was becoming more responsive to context. Three other, interrelated factors Bush -Brown identifies as influencing SOM's work at this time are important to highlight within the context of the design for the suburban Weyerhaeuser Corporate Headquarters campus. The first is the public's continued, some would say escalating, move toward suburban living and reliance on the car for transportation. With increasing pressure to convert undeveloped land for suburban uses, the second factor was the land -conservation movement, which was gaining momentum, particularly on the West Coast. The third and final issue was the energy crisis and drive to decrease reliance on oil (Bush -Brown 1983:17). Together, these external forces created an environment in which SOM's designs for suburban projects were not only becoming more visually responsive to the non -urban context, but also adaptive to pressures to conserve land and save energy. While the Weyerhaeuser Corporate Headquarters may be the fullest expression of the firm's response to these values, some of the campus' contemporaries that illustrate this shift from SOM's earlier, more urban palette are: > D90 Boots Headquarters, Beeston (Nottingham), England (1968); > Wells College's Louis Jefferson Long Library, Aurora, New York (1968); > University of Chicago's Behavioral Science Building, Chicago, Illinois (1969); and > Boise Plaza, Boise, Idaho (1971). The location of the SOM office responsible for designing a given project was important. During this stage of the company's history, the offices were regionally competitive (J. Ochsner, personal communication, May 8, 2019; P. Walker, personal communication, May 22, 2019). Interestingly, the genesis of the Weyerhaeuser Corporate Headquarters campus project was with Gordon Bunshaft (1909-1990) in SOM's New York City office. According to Peter Walker, Bunshaft was hired by Norton Clapp, who was the New York -based chairman of the board for Weyerhaeuser at that time. However, George Weyerhaeuser was reportedly unhappy with the "big city" quality of Bunshaft's submitted design. With George Weyerhaeuser's interest in grounding the headquarters in the company's West Coast home, the commission was then transferred to Chuck Bassett out of SOM's San Francisco office (P. Walker, personal communication, May 22, 2019). July 2020 Cardno Historical Context for the Weyerhaeuser Campus 4-13 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 4.3.2 Edward Charles ("Chuck") Bassett Edward Charles ("Chuck") Bassett (1921-1999), an architect with SOM, was the partner in charge of design for the San Francisco office for over two decades, a period that included the design and construction of the Weyerhaeuser Company's headquarters. Bassett was born and trained in Michigan, after which he worked with architect Eero Saarinen in Bloomfield Hills, Michigan, for 5 years. In 1955, Bassett joined the SOM office in San Francisco, where he remained until his retirement in 1981 (Pace 1999). Bassett was appointed Fellow of the American Institute of Architecture in 1977 (Pacific Coast Architecture Database 2019a). Bassett's notable work with SOM's San Francisco office spans the length of his 26 years with the firm. According to the Pacific Coast Architecture Database (Pacific Coast Architecture Database 2019a), a selection of the projects attributed to him includes: > Crown Zellerbach Corporation, Office Building #2, San Francisco, California (1957-1959); > John Hancock Mutual Life Insurance Company Office Building, San Francisco, California (1960); > Saint Aidan's Episcopal Church, San Francisco, California (1962-1963); > County of Alameda Coliseum, Oakland, California (1964-1966); > Australian Mutual Provident Tower and Plaza, Melbourne, Australia (1969); > Century City ABI Tower, Los Angeles, California (1971); > San Francisco War Memorial and Davies Symphony Hall, San Francisco, California (1977-1980); > First International Plaza, Houston, Texas (1980); and > City Hall, Columbus, Indiana (1981). Thus, with a few exceptions, Bassett's body of work was monumental in scale and commercial in use. In Bassett's New York Times obituary (Pace 1999), Allan Temko, former architecture critic of The San Francisco Chronicle, described the architect as "'a leader in the efforts of younger modern architects to seek alternatives to the arid formulas of the International Style." This harkens back to Woodward's 1970 comments about SOM's work as a whole (see above). Temko calls out the Weyerhaeuser campus as one of Bassett's most notable works and as "another beauty: it's so handsomely sited the building is like a dam overlooking a lake." 4.3.3 Sasaki, Walker and Associates (SWA) The partnership of Hideo Sasaki (1919-2000) and Peter J. Walker (born 1932) was formed in 1957 as SWA. While the formal partnership dates between 1957 and the 1970s, Sasaki and Walker maintained associations before and after the life of the company. Sasaki was chair of the landscape architecture program at the Harvard Graduate School of Design while maintaining the firm's Watertown, Massachusetts, office (TCLF 2019a). They met while Walker completed his graduate studies at Harvard University (P. Walker, personal communication, May 22, 2019). SWA were integral to the designs of significant projects nationwide, particularly those where architecture and landscape were closely integrated in concept and execution. These include: > Bell Laboratories, Holmdel, New Jersey, with architect Eero Saarinen Associates (1959); > Foothill Junior College, Los Altos, California, with architect Ernest Kump (1960); > Deere & Company Administration Center, Moline, Illinois, with architect Eero Saarinen Associates (1964); > Fashion Island, Newport Beach, California (1970); and 4-14 Historical Context for the Weyerhaeuser Campus Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus > Waterfront Park, Washington, D.C. (1972). While Sasaki maintained the East Coast practice of the firm, Walker opened and maintained their West Coast practice starting with the development of the Foothill Junior College project (P. Walker, personal communication, May 22, 2019). 4.3.4 Peter Walker Originally from California, Peter Walker began his career in landscape architecture at the University of California — Berkeley and Harvard University's Graduate School of Design. Prior to forming SWA, he worked for Lawrence Halprin and Associates. Walker was appointed Fellow of the American Society of Landscape Architects in 1975 and has been an influential leader throughout his career. He has published widely, took on the role of chair at both of his alma maters, and served on multiple design juries and boards, including University of Washington's Architectural Review Commission for many years (Pacific Coast Architecture Database 2019b; TCLF 2019b; P. Walker, personal communication, May 22, 2019). Landscape architect and university professor Thaisa Way refers to minimalism as being a defining characteristic of his work (T. Way, personal communication, May 8, 2019). With projects spanning over half a century, Walker's body of work is extensive and includes large-scale commissions in Germany, Switzerland, Japan, China, the Philippines, Singapore, South Korea, and Australia as well as throughout the U.S. Along with early projects such as Foothill Junior College and the Weyerhaeuser Corporate Headquarters campus, Walker was also responsible for landscape and site planning for: > Boeing Longacres Industrial Park, Renton, Washington (1994); > Novartis Headquarters Landscape Master Plan, Sculpture Plaza, and Forum, Basel, Switzerland (1999, 2005, and 2007); > Pixar Animation Studios, Emeryille, California (2000 and 2011); > Sydney Olympia Park, Sydney, Australia (2000 and ongoing); > U.S. Federal Courthouse, Seattle, Washington (2004); and > National September 11 Memorial, New York, New York (2011). Walker continues to practice as Principal of Peter Walker and Partners (PWP) Landscape Architecture (PWP Landscape Architecture 2019). 4.4 Federal Way Of the land owned by Weyerhaeuser at the time a new corporate headquarters was being conceptualized, a site in Federal Way was selected in part because of its location along two highways (Interstate 5 and State Route 18), ease of access to Sea-Tac Airport, and proximity to both Tacoma and Seattle (P. Walker, personal communication, May 22, 2019). Initially the campus was officially in unincorporated King County. The City of Federal Way incorporated after voter approval in 1990, but the historical events that led to this point date back to Native American settlements and trails. In written records, Captain George Vancouver explored the area in 1792 and encountered many Indians. In 1840, Hudson's Bay Company established a trading post in the area along an established Indian trail. Then came the 1850s surveys to build a road between Fort Steilacoom and Fort Bellingham. This road used existing trail networks, including one that passed through what is now Federal Way. The resulting road was named Military Road. The section between Pierce County and Seattle was completed in 1860 (Stein 2003). The next leap forward for transportation through the area was the construction of a new, federally funded West Coast highway, which would become U.S. Highway 99. Begun in 1915, the section between Seattle July 2020 Cardno Historical Context for the Weyerhaeuser Campus 4-15 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus and Tacoma opened in 1928. The stretch of the highway through the area either subsumed or ran parallel to Military Road. This "Federal Way" became the namesake for the developing school district and, over time, the area in general. The community created its first fire district —Fire District Number 22—by special election in 1944, followed in 1949 by its first fire station (Federal Way Mirror 2017). The Federal Way Commercial Club, the predecessor of the Federal Way Chamber of Commerce, was formed in 1946, and the Greater Federal Way News was established soon after. Businesses developed along the Highway 99 corridor. In 1955, the Federal Shopping Way Mall opened and became a popular shopping and amusement center for the whole area. A further boost to Federal Way's connectivity was the 1962 completion of the section of Interstate 5 that went through the area (Stein 2003). Weyerhaeuser began construction of its corporate headquarters within the well-connected network of highways at the end of that decade. 4-16 Historical Context for the Weyerhaeuser Campus Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 5 Campus Design and Construction 5.1 The Corporate Headquarters 5.1.1 Headquarters Planning and Design Process As documented in an unauthored, tabular report from December 1, 1965, housed at the Forest History Society's Carl A. Weyerhaeuser Library, the company researched a number of other existing corporate campuses during the planning stage. These campuses included: > Chase Manhattan Bank, New York, New York; > Deere and Company, Moline, Illinois; > General Mills, Golden Valley, Minnesota; > Union Carbide, New York, New York; and > Upjohn Company, Kalamazoo, Michigan. Of the 12 sites used for comparison, six were identified as SOM designs, and five were noted as having a suburban location. None were located west of Minnesota (Forest History Society 2019). Weyerhaeuser hired SOM to come up with a design for its new suburban corporate headquarters. In an oral interview, Peter Walker of SWA provided firsthand insight into the people and process that created the Federal Way Weyerhaeuser Corporate Headquarters campus. As described earlier, the relationship between Weyerhaeuser, SOM, and SWA began on the East Coast, but soon moved to the West Coast offices of both firms. Walker described the connection made from the start between himself, SOM's Chuck Bassett, and George Weyerhaeuser, noting that all three were similarly young in comparison to the original team proposed out of SOM's New York Office (P. Walker, personal communication, May 22, 2019). As the new president, George Weyerhaeuser was interested in moving the company's headquarters out of the city environment while entrenching it firmly on the West Coast (P. Walker, personal communication, May 22, 2019). The influence of George Weyerhaeuser's vision of tying the new headquarters with a shift in corporate identity under new leadership cannot be underestimated. Along with his own creativity, Chuck Bassett brought SOM's reputation for being the "go -to" firm for corporate campuses at the time (J. Ochsner, personal communication, May 8, 2019). Peter Walker brought his minimalist's vision and desire to test the boundaries between what is natural and what is human made (T. Way, personal communication, May 8, 2019; P. Walker, personal communication, May 22, 2019). George Weyerhaeuser represented the ideals of a company in transition. This was not solely a matter of younger leadership but a desire to change the image of the company from one that consumes resources to one that manages them, or, in the words of one of Weyerhaeuser's subsequent advertising campaigns, "The Tree Growing Company" (Mozingo 2011:141). Professor of Landscape Architecture Thaisa Way describes designed landscapes like Bloedel Reserve on Bainbridge Island, Washington, and the Weyerhaeuser Corporate Headquarters as "apologetic landscapes," whose very design emphasizes the desire of some industry leaders whose previous reputation may have been more often associated with environmental extraction to demonstrate their interest in environmental protection (T. Way, personal communication, May 8, 2019). Out of a number of different Weyerhaeuser -owned pieces of land, the chosen site was selected because it was near two freeways and the airport between Tacoma and Seattle (P. Walker, personal communication, May 22, 2019) (Figure 14).

In this undated plan from this early development period, the then -existing conditions are laid out and include roads and stands of trees. (Image courtesy of the Carl A. Weyerhaeuser Library, Forest History Society, Durham, North Carolina) The design process itself as described by Walker was highly collaborative. Meetings with both design firms and George Weyerhaeuser generally took place at Chuck Bassett's office in San Francisco, 5-18 Campus Design and Construction Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus California. "He had this office where the floors, walls, and ceiling were white .... There were no desks. There were a couple of tables for models but basically it wasn't an office, it was a studio and that's the way Chuck planned it .... Chuck was essentially holding school" (P. Walker, personal communication, May 22, 2019). According to Walker, the team was sometimes called "Chuck's Brats" because they were young enough to be students. Walker described an environment in which ideas flowed that went beyond the mere integration of architectural and landscape design concepts to the point where, oftentimes, it was difficult to pinpoint who came up with the genesis of a new direction. Speaking from the perspective of the landscape architect on the team, Walker noted, We worked with Bassett to try to extend his ideas and also to bring some ideas from the site back to the building. Out of that came this tiered level where the building was all planted.... Then, the parking stepped down the hill, so that when you came in and parked your car, you would walk right in to your floor. You wouldn't come in a front door and then go to an elevator; only guests would do that .... A lot of these ingenious ideas came out in those first days. It's hard to say whether they were landscape ideas or architectural ideas. (P. Walker, personal communication, May 22, 2019) Indeed, David Streatfield, Emeritus Professor of Landscape Architecture at the University of Washington, notes, "the large structure designed as a stepped dam in the center of a formal allee is as much a landscape as it is a building" (Streatfield 1980:59). The nature of this early design process calls to mind the concept of "total architecture" as described by Bauhaus School founder Walter Gropius in 1943 in Scope of Total Architecture, I have come to the conclusion that an architect or planner worth the name must have a very broad and comprehensive vision indeed to achieve a true synthesis of a future community. This we might call "total architecture." To do such a total job he needs the ardent passion of a lover and the humble willingness to collaborate with others, for great as he may be he cannot do it alone. The kinship of regional architectural expression which we so much desire will greatly depend, I believe, on the creative development of teamwork. (Peter 1958:36) Within this creative, collaborative context, the team worked on initial concepts and site planning. After considering over a dozen locations for the building, Bassett came up with the idea of "a bridge that spanned from hill to hill" and the overall design concept was established (P. Walker, personal communication, May 22, 2019). One earlier site plan developed by the team is illustrated in Figure 15 and Figure 16. The final plan included the tiered parking lots previously described by Walker (Figure 17, Figure 18, and Figure 19). Planting plans were supplied by SWA to identify which trees would be retained as well as areas that would be planted with new vegetation (Appendix A). Inside, the building introduced a new concept in office planning in the United States, that of the open plan or burolandschaft (Streatfield 1980:59). The idea was inspired by a trip the architecture team took to Scandinavia and Germany. The resulting design used furniture to shape the spaces rather than structural partitions, and afforded all employees views out over the landscape from where they worked (P. Walker, personal communication, May 22, 2019).

About half of the Tacoma headquarters staff-835 employees — moved into the building in April 1971. The other half would have to wait for future development at the campus. Chuck Bassett expressed the design team's pride in the project at the time, noting that it would not be complete until the landscape matured (Figure 26) ( Weyerhaeuser World 1971:2).

There are some who build little and talk a lot, and I would much rather be the other kind who builds and talks less. We tried very hard on this building and it has embraced almost four years from the start. It has been a wonderful, fantastic experience with an end result of which 1 and all of us at Skidmore, Owings and Merrill are very proud. Although you start out with something in your mind that is not quite defined yet, you have to wait four years before it happens, and it happens in such little bits and pieces, and over such a long period of time, that the wear and tear on some jobs often overcomes the excitement. This has certainly not been true here where all of us remain inherently devoted to the client and to the building. Good buildings require other kinds of chemistries besides hard work. They require a committed, involved and interested client; they require an interesting, challenging site, and they require a challenging program; and if we are lucky and have some talent, it requires that too. But with all of these things together, the total is greater than the individual parts and 1 think this is what happened on this job. Of course we wanted to make this a beautiful building by itself, as identity; of course we wanted to make it a delightful, wonderful place for people to work in. There are lots of buildings that don't do this and we were very firm in our purpose to accomplish this, but from a total point of view, I would consider these things as the least common denominator. If you cannot do these, then what the hell are you doing there in the first place? Now, everyone thinks the building is completed. I guess it is — 95 percent of it. We still have some things to do, and we have to tune it and get it just right — a process that will go on for the next three months. But to me and to the rest of our gang, the building is, actually, only about 80 percent or 75 percent complete because the important ingredient lacking here at the moment is, simply, maturity. The building has to have the ivy on these tipped burrs, rich and green and a foot thick, and falling all over these edges that you see. The lack edge has to become wonderful and soft and green, and the little willow trees out there have to reach maturity — which is ten years away. The meadow has to be worked carefully and seeded so it is a nice expanse of green, and all the parking lots which are standing there, rather bare at the moment, have to have the sycamore trees along the walk so that, as you approach the building, you will be walking down a lane of sycamore trees in an arched, tunnel -like form of green. And from the building, because of the sycamores, you will hardly be aware of the cars themselves. In the fifth floor gardens at the ends of the building, the yew hedges will be four and a half feet high — rich and deep and opaque, the way those hedges are — not the way they look now. All these things will settle in and become an inherent, integral part of the building and when that happens, then the building is complete. 1 cannot but look at it now and feel that there ought to be some way in our vast technological resources to hurry up God, and things like this. But, as an architect, I know that is useless and I have to wait. We, at SOM, are very proud of the building. We are even prouder of our relationship with the whole Weyerhaeuser family. They are a magnificent group of people, and speaking for everyone in our gang and myself, I would like to thank you all. Figure 26. Part of a speech given by SOM architect, Chuck Bassett, to a meeting of the corporation's shareholders in 1971. (Weyerhaeuser World 1971:2) 5-26 Campus Design and Construction Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 5.1.2 Planning for Expansion When half of the Tacoma staff moved into the new headquarters building in 1971, the employee magazine noted that the other half were waiting for new buildings to be developed on nearby land (Weyerhaeuser World 1971:2). Recalling the process of site planning, landscape architect Peter Walker observed that there was no single plan selected for the entire headquarters property. Certain concepts emerged, such as the intention to set aside land to the north and east of the headquarters for other corporate purposes, as shown in Figure 15, Figure 27, and Figure 28. Over the course of the history of the corporate campus, Weyerhaeuser Company moved forward on developing some of the areas identified in these site plans. While detailed designs were not established on early site plans, the main concept that was thread throughout the ongoing planning process was that each stage of development would have a distinct design and be separated from one another by woods (P. Walker, personal communication, May 22, 2019). Although Weyerhaeuser Company did not follow this guiding principle on more recent development at the north end of the property, it was carried out for the development of the second major stage of the campus's construction, the Weyerhaeuser Technology Center (WTC) (Figure 29).

Site plans identify the California offices of SOM and SWA as the design team (Figure 28). In an interview, Peter Walker also confirmed that he and Chuck Bassett were members of the team for this stage of the project (P. Walker, personal communication, May 22, 2019). 5.1.3.2 WTC Construction and Opening Site excavation for the construction of the WTC began in 1976 and continued through its dedication in 1978 (Figure 30 through Figure 34). Upon completion, one design publication noted that, "in contrast to the highly visible headquarters building, on view from two flanking highways, the Technology Center is dropped into the forest, all but invisible from any distance (Interior Design 1979: no page numbers). Thus, the original site planning concept for each new development on the campus to have a distinct design aesthetic was actualized in this second major construction project during the historical period of significance.

In some cases, the company removed the buildings and streets in order to achieve the 1969 design such as immediately north and east of the headquarters building (Figure 21). In others, Weyerhaeuser acquired the land later and used the existing buildings for different corporate purposes. The four buildings that were constructed prior to the headquarters building and landscape and later used by Weyerhaeuser Company are described below. 5.3.1.1 Former Puget Sound Power & Light Company Service Building This building was designed in 1963 and built in 1964 for the precursor to Puget Sound Energy to serve the Auburn and Federal Way area (Figure 41). At the time it was constructed, its address was 2835 South 344th Street, which no longer exists. Today, it is located at the southern end of the headquarters property and contains a loading dock and office area. The property was acquired by Weyerhaeuser at an unknown date. Its function on the campus site is unknown. Figure 41. A King County Assessor photograph from 1964 showing the Puget Sound Power & Light Company Service Building soon after completion. (Image courtesy of the Washington State Archives) 5.3.1.2 Project House 1 According to King County Assessor records, this former residence was also constructed in 1964 (King County Assessor 2019). The two-story dwelling contains a side entrance and a detached garage on the street side of the property. The name of the original owner is as yet unknown. King County Assessor records note that Weyerhaeuser Company purchased the property from an escrow company in 1988 (King County Assessor 2019). A long-time Weyerhaeuser Company employee, Andy Bylin, noted that the building was converted by the corporation into meeting spaces a number of decades ago (A Bylin, personal communication, June 26, 2019). 5.3.1.3 Project House 2 Weyerhaeuser Company constructed this building in 1969, as indicated in project plans and King County Assessor data (Weyerhaeuser Company 2019b and King County Assessor 2019) (Figure 42). The July 2020 Cardno Campus Design and Construction 5-41 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus northern extension of Weyerhaeuser Way South was not yet completed at the time of construction. Although the property is accessed from that street today, it was given an address of 32820 32"d Avenue South. This address relates to a previously existing road (32"d Avenue) that once passed east of the building. As a result, its orientation may have changed, whereby what may once have been its front elevation (southeast) now faces away from the road from which it is now accessed (Weyerhaeuser Way South). Weyerhaeuser Way South was constructed ca. 1978, almost a decade after Project House 2 was built. It was designed as "Research House 2" in the form of a single-family residence with detached garage; the garage was never built (Weyerhaeuser Company 2019b and A Bylin, personal communication, June 26, 2019). The building is known anecdotally as the "Glue House", reportedly because it was built without nails (A Bylin, personal communication, June 26, 2019). However, the plans provided by Weyerhaeuser Company (2019b) do not include details of fastenings or other adhesives. In addition, these details were not visible on the exterior of the building during the reconnaissance -level survey. As a result, the suggestion that the building was constructed without nails has not been confirmed. There is no evidence that the building was ever used as a residence, despite the name. During the period of Weyerhaeuser Company occupation of the headquarters property, Project House 2 was used as an archives building and offices for a number of work groups. The building was last used by the lands real estate team at the time the corporation moved its headquarters to Seattle in 2016 (A Bylin, personal communication, June 26, 2019). t S 7 - 7v Figure 42. A 1971 King County Assessor photograph of Project House 2 shows what was then its front elevation on the now non -vacated 32"d Avenue South. Today it serves as the building's rear elevation. (Image courtesy of the Washington State Archives) 5.3.1.4 King County Fire District Number 22 Fire Station King County Fire District Number 22 constructed this fire station in 1969 with the hose tower completed in 1971 (Washington State Archives 2019) (Figure 43). Fire District Number 22 was created by special election in 1944. In 1949, its first fire station, which is no longer standing, was opened in a prefabricated Quonset but at the corner of 18t" Avenue and 308t" Street South, Federal Way, approximately 1.5 miles northeast of the 1969 fire station. Other new stations were built as adjacent fire districts merged and the completion of Interstate 5 nearby in 1962 led to growth in the area. These included a station opened in 1959 on 28th Avenue South, Federal Way (Federal Way Mirror 2017). This 1959 station appears to have 5-42 Campus Design and Construction Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus been altered to serve as the Steel Lake Park maintenance facility today (Google Maps 2020). Two more stations opened in the late 1960s (Federal Way Mirror 2017). When King County Fire District Number 22 Fire Station was opened in the area where the new Weyerhaeuser Corporate Headquarters was planned, the earlier road infrastructure illustrated in Figure 14 was still present. The address given to the new fire station was 2821 South 336t" Street. Today, it is accessed off Weyerhaeuser Way South and is used as the office and storage facilities for Osaka Garden Services, the on -site landscaping company that maintains the former headquarters campus property. The date the former fire station was acquired by Weyerhaeuser Company has yet to be determined. However, King County Assessor records indicate that it was remodeled in 1997 and 1998, with new, prefabricated buildings added in 2001 and 2002 (King County Assessor 2020). This suggests potential acquisition by Weyerhaeuser Company for the use of its landscapers during the 1990s. This may have been when the hose tower was removed, although this has not been confirmed. Figure 43. A 1969 King County Assessor photograph of the former fire station shows its front (north) elevation prior to construction of the hose tower. (Image courtesy of the Washington State Archives) 5.3.2 Rhododendron Species Botanical Garden Weyerhaeuser Company began leasing land on the campus to the Rhododendron Species Foundation in 1974 to house their collection, which had been previously located in Oregon (Rhododendron Species Botanical Garden 2020). Peter Walker noted that SWA landscape architect William Callaway (1943- 2014) produced the original design for the rhododendron dell (P. Walker, personal communication, May 22, 2019). A number of buildings and structures were constructed in 1974 and 1975 to house and care for the collection (Washington State Archives 2019) (Figure 44 and Figure 45). The collection was moved from Oregon in 1975 and the first open house at the garden was held in October of 1979 (Seattle Times 1979:A15 and 1981:B2). The garden began keeping regular opening hours in 1981, although work on the design of the garden continued (Figure 39). By 1981, the number of species held by the Rhododendron Species Foundation on site had risen from an initial 263 to a total of 475 species (Seattle Times 1981: B2). After opening to the public, the garden was reorganized according to taxonomy, a significant change from the SWA plan. Replanting was completed in 1984. Other changes to the garden included the construction July 2020 Cardno Campus Design and Construction 5-43 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus of a new greenhouse in 2005, the development of a tropical conservatory and a Victorian "stumpery" for fern collections in 2009, and the addition of other species such as azaleas, blue poppies, and magnolias over the years. Today, the garden occupies 22 acres of an expanded trail network at the southeastern end of the campus (Rhododendron Species Botanical Garden 2020). From its opening to the present day, the Rhododendron Species Botanical Garden has provided a public amenity on the Weyerhaeuser Corporate Headquarters campus. The timing of its addition to the campus coincided with the corporation's continued efforts to position itself as the "Tree Growing Company" (Seattle Times 1977:D2). The garden could be perceived as evidence of the corporation's interest in protecting and displaying a diverse range of plant species. In visiting the garden, the public was also presented with the headquarters' surroundings as an example of the Weyerhaeuser Company's approach to forest management. Figure 44.

This King County Assessor photograph shows the rhododendron garden's Potting and Storage Shed, which was constructed west of the Lath House in 1975 (Image courtesy of the Washington State Archives) 5.3.3 Pacific Bonsai Museum The Pacific Rim Bonsai Collection also acquired facilities on the Weyerhaeuser Corporate Headquarters campus in the late 1980s. The facility for the collection was built adjacent to the Rhododendron Species Botanical Garden. It was officially opened by George Weyerhaeuser and former Washington first lady, Jean Gardner in 1989 in honor of the state centennial. Renamed the Pacific Bonsai Museum in 2013, the organization's website states that "the Collection was established to symbolize Weyerhaeuser's long-term commitments to its customers, its community, and its forest resources (Pacific Bonsai Museum 2020)." 5.4 Weyerhaeuser Company's Other Recent Campus Alterations When comparing site plans from the 1970s to more recent aerial imagery, it is evident that Weyerhaeuser Company did not embark on major redevelopment on the campus following completion of the WTC until after 1990 (Figure 2, Figure 27, Figure 28, and Figure 46). The corporation's alternations that occurred during redevelopment, as described in King County Assessor records (2019) and by Andy Bylin, long- time Weyerhaeuser employee and current facilities manager, over a series of site visits and email correspondence with Cardno throughout 2019, include: > Modifications to the WTC, including painting of the cedar cladding, window and door replacement, expansion of the service yard, conversion of the designed hay fields to lawn, and abandonment of the roof gardens above both entrance vestibules(Figure 47 to Figure 49); > Relocation of the original helipad and addition of a second helipad to the southwest side of the headquarters building in the 1980s (Figure 50); and > Construction of multiple new commercial and warehouse buildings under different owners at the north end of the former campus site between 1999 and 2007. This stage of development failed to follow the July 2020 Cardno Campus Design and Construction 5-45 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus historical site planning concept of utilizing tree buffers to separate different parts of the campus (Figure 51). Periodic management of the ivy, trees, and forests has also taken place to control the undergrowth and protect the health of the vegetation as per the concomitant agreement (Weyerhaeuser Company Concomitant Pre -Annexation Zoning Agreement 1994; A. Bylin, personal communication, various dates throughout 2019). 5-46 Campus Design and Construction Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Figure 46.

Yet with ever-increasing Modernist properties reaching the standard thresholds for consideration for local, state, and national registers, designations have followed. Some significant suburban corporate campuses have been listed in the NRHP. Notable examples are: General Motors Technical Center, construction completed in 1956 in Warren, Michigan; Eero Saarinen (architect), Thomas Dolliver Church (landscape architect). The historic property was initially designated in the NRHP on March 27, 2000, and later listed as a National Historic Landmark in 2014. This property was listed under national significance for its association with corporate research and development during the post-war period (Criterion A) and with Alfred P. Sloan, Jr. and Harley Jefferson Earl (Criterion B), as well as its architectural significance (Criterion C). Its period of significance is 1949 to 1970. With the latter part of the period of significance falling outside the common minimum threshold of 50 years of age, it was also listed using Criteria Consideration G (Kavenagh et al. 1999). The 600-acre site has 22 contributing and nine non-contributing features. All are buildings or structures. The "high -style modernist landscape" —including scenic views, circulation plan, tree planting, and landscaped parking lots —is described in some detail in the nomination form, but no landscape features are listed as either contributing or non-contributing. However, landscape architecture is listed as an area of significance, and landscape architect Church is listed alongside Saarinen as one of the architects of the project (Kavenagh et al. 1999). 2. Reynolds Metals Company International Headquarters, completed in 1958 in Henrico County (near Richmond), Virginia; Gordon Bunshaft of SOM New York office (architect), Charles F. Gillette (landscape architect). The 121-acre historic property was designated in the NRHP on April 11, 2000, as an "office building" with the following contributing resources: > Executive office building; > Unnamed service building; > Greenhouse; > Landscaped park; and > Reflecting pool (Sadler and Witt 1999). The area of significance for the property is architecture (NRHP Criterion C), and the period of significance is 1958. The four non-contributing buildings dating from 1968 to the date of designation. Notably, this historic property was listed in the NRHP prior to it reaching the standard age threshold and was thus approved under Criteria Consideration G for properties that have achieved significance within the past 50 years (Sadler and Witt 1999). 3. The Connecticut General Life Insurance Company Headquarters, construction completed in 1957 in Bloomfield, Connecticut; Gordon Bunshaft of SOM New York office (architect), Isamu Noguchi (landscape architect). The historic property was designated on December 29, 2009, for national- and state -level significance for its associations with patterns of community planning and development (NRHP Criterion A) and its architecture (NRHP Criterion C). The period of significance is 1954 to 1957. This 30.52-acre property has only one contributing element: > Wilde Building, which contains the main building, north wing, and cafeteria (Hembree 2009). July 2020 Cardno Evaluation of Significance 6-1 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Non-contributing elements are the 1972 parking garage and associated pedestrian walkway. While the nomination report refers to a number of landscape features that remain intact, the landscape is not a listed contributing element to the designated property (Hembree 2009). 4. Virginia National Bank Headquarters, construction completed in 1967 in Norfolk, Virginia; Roy O. Allen and J. Walter Severinghause of SOM's New York office with local firm Williams and Tazewell (architects). This complex was listed for local significance as a historic district under NRHP Criteria A (for commercial importance) and C (for architectural importance) on August 15, 2016. The contributing resources are: > Skyscraper; > Parking garage; and > Plaza with sunken pool. Non-contributing elements post-date the 1965 to 1968 period of significance (Pollard 2016). With these four examples, we see that integrated landscapes —hallmarks of the suburban campus typology —are not consistently represented in formal designation. As of the date of this report, no properties associated with Charles Bassett are known to have been listed in the NRHP. At a local level, one of his buildings, the 1959 Crown Zellerbach Building, has been listed as a San Francisco Designated Landmark since 1987. Relevant to the Pacific Northwest context, SOM's San Francisco office was involved in the design of the 1958 Norton Building, which was designated a Seattle City Landmark in 2008. While primarily designed by local architects Bindon & Wright, SOM worked in consultation as "the nation's preeminent practitioner of highrise design during this era" (Gordon 2008:4). However, it was not Bassett who represented SOM on the project but Elliott F. Brown, Alan S. Robinson, and Myron Goldsmith. Similarly, Modernist landscapes as a whole are underrepresented on heritage registers. Charles Birnbaum (2016; C. Birnbaum, personal communication by email, May 25, 2019), founder of TCLF in 1998 and current president and CEO of the organization, notes a number of Lawrence Halprin NRHP listings that are listed in heritage registers, namely Park Central Square in Springfield, Missouri (listed 2009), Heritage Park Plaza in Fort Worth, Texas (listed 2009), and Portland Open Space Sequence in Portland, Oregon (listed 2013). Dan Kiley's (1912-2004) work has also received some recognition through NRHP listing, including Miller House Garden in Columbus, Indiana, which was designated as a National Historic Landmark in 2000. As noted with Bassett above, no landscapes designed by Walker have been identified as listed in the NRHP. 6.2 NRHP Eligibility Evaluation The former Weyerhaeuser Corporate Headquarters campus, as defined below, possesses integrity of location, setting, design, material, workmanship, feeling, and association, which are defined in NHPA (36 CFR § 800.16). The property as defined is recommended eligible for the NRHP as a historic district under Criteria A and C and Criteria Consideration G at a national level of significance under the following analysis: > Criterion A: The former Weyerhaeuser Corporate Headquarters campus has had significant associations with community planning and development in introducing the corporate campus to the West Coast, a form of corporate planning that would become the template to respond to corporate growth in the region. It has also played a pivotal role in representing Weyerhaeuser Company's changing public image as a forest management corporation. As a result, the campus is recommended eligible for listing in the NRHP as a historic district under Criterion A; 6-2 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus > Criterion B: The former Weyerhaeuser Corporate Headquarters campus is not directly associated with the lives of persons significant in our past as distinct from their roles in the significant events captured under Criterion A, or design significance addressed under Criterion C. The campus is, therefore, not recommended eligible for listing in the NRHP under Criterion B; > Criterion C: The former Weyerhaeuser Corporate Headquarters campus is an exceptional example of built heritage that responds to its Northwest context by integrating buildings and landscape into a synergistic whole while using materials, design, and workmanship to reflect the corporate identity projected by the Weyerhaeuser Company at this time in its history. The campus is also an outstanding example of the work of landscape architect Peter Walker (SWA) and architect Edward Charles Bassett (SOM). The former Weyerhaeuser Corporate Headquarters campus is recommended eligible for listing in the NRHP as a historic district under Criterion C; > Criterion D: The significance of the former Weyerhaeuser Corporate Headquarters campus is fully visible in its above -ground built features, and the historical record has been found to be rich in detail. Further research is unlikely to yield new avenues of historical significance not otherwise captured under Criteria A, B, and C. In addition, the campus has not been found to possess archaeological significance (Costa et al. 2018 and Payne et al. 2020). Additional archaeological research is also unlikely to yield new information important in our history. Therefore, the campus is not recommended eligible for listing in the NRHP under Criterion D; and > Criteria Consideration G: The former Weyerhaeuser Corporate Headquarters campus, as defined below, is a historic property so exceptional in historical and design importance that it has achieved significance within the past 50 years. It is recommended eligible for listing in the NRHP under Criterion Consideration G. Considering that both the main headquarters area and the WTC were designed on the whole by the same team and, at the same time, all associated design elements are less than 50 years of age, following NPS guidance on determining eligibility under Criteria Consideration G was critical to the analysis. In their work on NRB 22, "Guidelines for Evaluating and Nominating Properties that have Achieved Significance within the past Fifty Years," Sherfy and Luce note the following: Properties that achieved significance within the past 50 years may be listed in the National Register of Historic Places, according to the National Register Criteria for Evaluation, only if they are of "exceptional importance," or if they are integral parts of districts that are eligible for listing in the National Register. This principle safeguards against listing properties which are of only contemporary, faddish value and ensures that the National Register is a register of historic places .... The passage of time is necessary in order to apply the adjective "historic" and to ensure adequate perspective. (Sherfy and Luce 1998:1) The guidelines note that the term "exceptional' is not defined in the criteria, because what is covered under this term "cannot be fully catalogued or anticipated" (Sherfy and Luce 1998:1). Recommended methods of evaluating whether a resource younger than 50 years of age is exceptional that are applicable to a historic designed landscape like the Weyerhaeuser Corporate Headquarters campus include: > Understanding its context to determine those features that "best illustrate or represent the architectural, cultural, or historical values being considered" (Sherfy and Luce 1998:3); > Uncovering scholarly evaluation of the resource, since "a case can be more readily be presented and accepted for a property that has achieved significance within the past 50 years if the type of architecture or its historic circumstances with which the property is associated have been the object of scholarly evaluation" (Sherfy and Luce 1998:4); and > Locating a property within a significant movement, such as the Cold War, whose period of significance may continue into a timeframe that is less than 50 years old. In such instances, July 2020 Cardno Evaluation of Significance 6-3 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus resources should be compared to others associated with that movement regardless of age (Sherfy and Luce 1998:6). The proposed historic district possesses a high level of integrity. The innovative and influential design of the headquarters and its associated landscape is noted in scholarly research and has received multiple awards. These awards include the American Institute of Architects (AIA) 1972 Honor Award, the Bartlett Award for accessibility in 1972, the American Society of Landscape Architects (ASLA) Merit Award in 1972, the ASLA Classic Award in 1998, and the especially prestigious AIA National 25 Year Award in 2001 (AIA Journal 1972:37, Skidmore Owings & Merrill 2020, and PWP Landscape Architects 2020). The continued development of the campus not only represented the corporation's changing projected image as a forest management company, it also played a pivotal role in introducing the corporate campus to the West Coast. Cardno recommends that the Weyerhaeuser Corporate Headquarters campus satisfies Criterion Consideration G. The recommended period of significance for the district is 1969 to 1979. This period encompass the completion of the design and construction of the headquarters and its surrounding landscape (1969- 1971), construction of Project House 2, completion of the WTC design and construction activities (1975- 1978), and the initial construction and public opening of the Rhododendron Species Botanical Garden (1975-1979). Only those buildings, structures, and landscape features that have been found to relate directly to Weyerhaeuser Company's occupation of the site during this time period are recommended as elements that contribute to the significance of the proposed historic district. Given the highly integrated nature of this historic designed landscape, recommending individual eligibility for the NRHP for may be inappropriate for a number of historic features whose significance is tied to the whole. Discussion regarding any individual building, structure, object, or landscape feature that is considered eligible for listing in the NRHP on its own merits is provided in Section 6.6. 6.3 Historic District Boundary Analysis NRB 15, "How to Apply the National Register Criteria for Evaluation," describes the physical characteristics of a historic district as a concentration, linkage, and continuity of features. "The identity of a district results from the interrelationship of its resources, which can convey a visual sense of the overall historic environment or be an arrangement of historically or functionally related properties" (NPS 1997a:5). Determining an appropriate property boundary is critical to the integrity of the historic property and its ability to accurately represent its significance. As described in NRB 21 and 12, "Defining Boundaries for National Register Properties," factors to consider include interpreting the integrity of the property and comparing the current and historical setting and use (Seifert 1997:2-3). Seifert summarizes the guidelines for boundary determination as follows: > Select boundaries to encompass but not exceed the extent of the significant resources and land areas comprising the property; > Include all historic features of the property, but do not include buffer zones or acreage not directly contributing to the significance of the property; > Exclude peripheral areas that no longer retain integrity due to alterations in physical conditions or setting caused by human forces, such as development, or national forces, such as erosion; and > Include small areas that are disturbed or lack significance when they are completely surrounded by eligible resources. "Donut holes" are not allowed. (Seifert 1997:2) The recommended boundary for the proposed Weyerhaeuser Corporate Headquarters Historic District encompasses most of the area known to have been proposed by the company for its headquarters complex at the time the 1969 plans were finalized (Figure 52). The areas excluded from the 6-4 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus recommended boundary lie to the north of the original site and follow existing parcel lines that demarcate the subdivided parcels that were developed between 1999 and 2007 (King County Assessor 2019). Not only did this development take place in the recent past, it also failed to follow the concept defined by the original design team of surrounding each stage of campus development with tree buffers. East of Weyerhaeuser Way South, the proposed northern boundary of the district ends at Parcel 1521049201, which is owned and managed by the Washington Department of Fish and Wildlife as a water access facility. West of Weyerhaeuser Way South, the proposed northern boundary of the district runs east -west along the parcel boundaries associated with the mixed commercial district to the north held by a variety of different owners. As currently configured, the following privately owned parcels lie north of the proposed district boundary in this area, with current uses as identified by the King County Assessor (2020): > Parcel 2154650170 — Public utility use, retention pond > Parcel 2154650080 — Office building use > Parcel 2154650110 — Vacant industrial use > Parcel 2154650160 — Public utility use, retention pond > Parcel 2154650180 — Reserve/Wilderness area The proposed NRHP-eligible historic district is bounded: > At the north by the parcel boundaries that form a continuous, forested, east -west line ca. 500 feet south of South 323rd Street, then crossing Weyerhaeuser Way to the property south of the Washington Department of Fish and Wildlife access road to North Lake; > At the west by Interstate 5; > At the south by State Route 18; and > At the east by Weyerhaeuser Way at the south end, and following parcel boundaries roughly at the point where Weyerhaeuser Road meets Weyerhaeuser Way to link to North Lake, which then forms the remaining eastern boundary. What follows is a description of which buildings, structures, and landscape features are recommended as contributing to the significance of the property.

Proposed NRHP-eligible historic district boundary. 6-6 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 6.4 Recommended Contributing Features to NRHP-Eligible Historic District Most of the buildings, structures, fixed objects, and landscape elements found within the proposed historic district boundary are recommended as contributing to the significance of the historic property (Figure 52 and Appendix B-1). As described in NRB 16a, a "contributing" building, site, structure, or object: Adds to the historic associations, historical architectural qualities, or archeological values for which a property is significant because it was present during the period of significance, relates to the documented significance of the property, and possesses historic integrity or is capable of yielding important information about the period, or it independently meets the National Register criteria. (NPS 1997b:16) As a recommended -eligible NRHP historic district, the former Weyerhaeuser Corporate Headquarters campus has an array of contributing resources ranging from landscape features to buildings, structures, and objects. Below is a description of contributing resources, which are illustrated on maps provided in Appendix B-1. A tabular summary is found at the end of this section in Table 1. Note that at the core of the cultural landscape's significance is the integration of landscape and architectural features; they are subdivided below for organizational purposes and do not imply a hierarchy of significance. 6.4.1 Corporate Headquarters Structural Elements, completed ca. 1971 Designed as an integrated, architectural whole, the exterior and interior spaces have an exceptionally high level of integrity. Recommended contributing features easily illustrated on Appendix B-1 are marked with letters of the alphabet as described below. 6.4.1.1 Building (Map Identification (ID) "A", Appendix B-1) The headquarters building itself is a five -story, ca. 358,000-square-foot, steel -frame structure characterized by its horizontal, linear form of projected, fluted, concrete planters alternating with inset, frameless, nearly floor -to -ceiling glazing (Figure 53 through Figure 57). Stout, smooth, concrete piers are exposed throughout interior and exterior spaces. A continuous promenade paved with crushed, pink gravel wraps around the fourth floor of the building (see Section 5.5.2). The shallow -pitch, copper -clad, pavilion -style roof is flat in its interior, providing a lightness in form. Oriented on an east -west axis, the building's location within the landscape emphasizes its appearance as a bridge or dam forming the pond to the north. Floors have different overall volumes, decreasing as the floors rise, creating a subtle ziggurat. With the lower floors having the appearance of being sunken into each corresponding parking level, the overall effect is of a building growing out of the landscape.

View of the headquarters building from the southern meadow. 6.4.1.2 Headquarters Parking Lots and Access Driveways (Map ID `B", Appendix B-1) Also contributing is the design of the parking lots, six in all, with access off Weyerhaeuser Road (Figure 58 through Figure 63). Groups of three radiate north- and south -ward from the eastern and western ends of the building, each linked to a different floor. This allows staff working on levels 1, 2, and 3 to have direct access from the parking lots to their floor without need of an elevator. Significant landscape features and street furniture for the parking lot are addressed in Section 5.5.2. Fourth -floor driveway access provides the public entrances at the eastern and western ends. Each driveway leads to a roundabout at each of the two main entrances, designed with radiating paving of plain concrete and crushed red gravel. The art within the roundabout at the west entrance —Guardian Rock —is described in Section 5.5.3. Along the driveway, a projecting roof protects additional parking spaces. 6-10 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Figure 58.

Contributing resources in this category are: > The ivy planting on the building itself, > Meadows that form a north -south axis "through" the building from State Route 18 to Interstate 5 (Map ID "C"), > Pond to the north of the building (Map ID "D"), > Managed woods of evergreen and deciduous trees captured within the circulation road (Map ID "E"), and > Hardscaping and planting schemes that surround the headquarters building, headquarters parking lots, and pond (Map ID "F"). These features include sidewalks paved in pink, crushed gravel with ivy planted in linear and square, sunken planters within allees of sycamore trees. Figure 64. Ivy planting on fluted concrete. 6-14 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Figure 65.

Guardian Rock, a work of art commissioned by SOM in 1970, is installed in the roundabout at the western entrance to the fourth floor of the headquarters building (Map ID "G"). Sculptor Gordon Newell selected the stone from Finegold Ranch School near Fresno, California (House n.d.). The flagpole on the eastern side of the pond is also an early feature of the campus (Map ID "H"). According to notes on a historical corporate photograph it is, "120' tall, plus base; laminated wood weighs 9,400 lbs. Done in our Cottage Grove, Oregon plant." A commemoration plaque was added in 1978 in honor of Norton Clapp's retirement as chairman of the board. Finally, street furniture dating to this early period of development includes tall lighting standards on square glulam posts in the parking lots and around the circulation drives, concrete sidewalk lighting fixtures to and from headquarters parking lots, and exterior waste receptacles with pink, crushed gravel cladding to match walkways.

Waste receptacles without the pink gravel are non-contributing. 6.4.4 Campus -Wide Circulation Roads, completed ca. 1971 and ca. 1978 (Map ID "I", Appendix B-1) The circulation road around the main headquarters landscape was an important element of the 1969 design. This historic circulation road is composed of Weyerhaeuser Road as it circumnavigates the headquarters area, the section of South 336th Street that connects Weyerhaeuser Road at its northwestern end and connects with the roundabout with Weyerhaeuser Way South, Weyerhaeuser Way South from the roundabout with South 336th Street to the northeastern end of Weyerhaeuser Road. The roundabout was built circa 2005 so is not included with the contributing circulation road. In addition, Weyerhaeuser Way South was also proposed to continue north of the main headquarters area, although its path was conceptual in initial plans. Kroll Map Company Atlas of Seattle maps from 1970-1971 and 1975 indicate that the extension of Weyerhaeuser Way South north of South 336th Street to South 320th Street took place in tandem with the development of the WTC (Kroll Map Company 1971, 1975). The pavement of the circulation roads is not a contributing element due to ordinary, periodic replacement, but the configurations with curving lines is highly significant to the experience of the campus, giving the driver the feeling of being in a forest punctuated by sweeping views of the headquarters building. Campus -Wide Wooded Buffers, completed ca. 1971 and ca. 1978 (Map ID "J", Appendix B-1) Related to the experience of both the campus circulation roads and the meadows, wooded buffers were identified by designer Peter Walker as an important element of the campus landscape (P. Walker, personal communication, May 22, 2019) (Figure 77 through Figure 81). These buffers were managed by Weyerhaeuser Company, which included cycles of understory clearance for the health of the woods as a whole (A. Bylin, personal communication, 2019). They provide the forest -like setting for other contributing elements and, as noted by Walker, were to be a hallmark of the long-term site planning vision, whereby each stage of future development would be set within its own tree buffer. A prescribed buffer size was not specified by landscape architect Peter Walker as the depth needed to provide the woodland setting would July 2020 Cardno Evaluation of Significance 6-21 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus depend on the site conditions, including the tree and undergrowth species, their ages, and their health (P. Walker, personal communication, May 22, 2019). In addition, there is no universally accepted industry standard on buffer widths, either to frame views or to represent a 50-year-old softwood forest. The concomitant agreement originally drawn up between Weyerhaeuser Corporation and the City of Federal Way, dating August 23, 1994, contains a provision for a managed forest buffer on parts of the eastern edge of the campus along sections of Weyerhaeuser Way South. There is no such provision for a forest buffer along the meadows or on Weyerhaeuser Road in the concomitant agreement (Weyerhaeuser Company Concomitant Pre -Annexation Zoning Agreement 1994). On -the -ground conditions are the most informative source of information to determine the buffer width needed to provide sufficient tree cover to frame views and "represent the character of a softwood forest at 50 years or more maturity and to provide open meadows," as described in the concomitant agreement (Weyerhaeuser Company Concomitant Pre -Annexation Zoning Agreement 1994:C-3). For the purposes of evaluating the former Weyerhaeuser Corporate Headquarters campus for NRHP eligibility, Cardno recommends using the 50-foot tree buffer standard provided in the concomitant agreement for wooded areas adjacent to a city or county road (Weyerhaeuser Company Concomitant Pre -Annexation Zoning Agreement 1994:C-2).

July 2020 Cardno Evaluation of Significance 6-25 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 6.4.6 Weyerhaeuser Technology Center (WTC), completed ca. 1978 The second significant development at the campus by the same firms during the period of historical significance was the construction of the WTC building, its associated parking lots, and access driveways. A research and development facility was conceptualized at the outset of the project to centralize corporate functions at the campus. On this stage of the project, SOM was represented by John Merrill as partner in charge, Charles Bassett as partner in charge of design, and Richard Foster as design associate partner. Peter Walker of SWA continued to work on site planning and landscape design. Although the building was designed to be expanded at the administrative end, these expansions never materialized. Weyerhaeuser Company leases a small portion of the WTC building. The largest tenant in the building today is International Paper Company. 6.4.6.1 WTC Building (Map ID "L ". Appendix B-1) The WTC building is a large, rectangular, two-story, flat -roof, concrete- and glulam-framed structure with cedar lap siding and nearly full -height (three-quarters) glazed walls with window units set in metal frames (Figure 84, Figure 85, and Figure 86). Two entrances are inset into the north and south elevations, providing a visual break between the administrative (eastern) and research (western) sides of the facility. Each entrance contains a circular vestibule with a glazed, sliding door system that replaced the original units. A basement houses the services. The building's setting includes lawns north and south of the administrative (eastern) end of the building and tree stands to the east. Access driveways terminate at a loop at each of the two entrances. To the west of the building is a loading dock and paved yard with a number of structures that date to the 1990s or later. Parking lot landscaping is located to the north and south of the service yard. A number of alterations have taken place as shown in a comparison of the current site conditions and historical plans and photographs. Originally the cedar siding was unfinished in the belief that it would weather to grey naturally. However, instead of performing as intended, the cedar siding was subject to water stains in the Northwest climate. As a result, the siding was later painted grey. Peter Walker's contributions included roof gardens over the two entrance vestibules and hay fields north and south of the building. Over time, Weyerhaeuser Company abandoned the regular maintenance of the roof gardens and converted the hay fields to mown lawn. Finally, the service yard was doubled in size ca. 1990, which eliminated the tree stands that originally lined the perimeter driveway at this end. The non -historic buildings and structures were also added at that time. 6-26 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Figure 84.

West elevation of the building and loading dock area. The fire hydrant marks the original western edge of the yard. Because of significant alterations, the service yard is recommended as a non-contributing element to the historic district. 6.4.6.2 WTC Parking Lots, Circulation Driveways, and Landscaping (Map ID "M" and "N", Appendix B-1) As with the headquarters area, the parking lots and their associated access driveways (Map ID "M") are integral to the design of the WTC. Each range of three parking lots fans out in a truncated arc north and south of the building (Figure 87 and Figure 88). Parking lots contain light standards similar to those at the Headquarters. Two driveways provide access to all six parking lots. The main driveway also provides direct access to the northern and southern entrances of the building. The perimeter driveway provides access to the service yard, parking lots, and detention pond. The driveways are lined with stands of trees. The parking lot landscaping consists of trees and understory vegetation (Map ID "N"). The landscaping screens the parking lots from views to and from the WTC building as well as each other. While there were originally four lots constructed, early site plans indicate that an additional lot to the outside of each set was identified from the outset. Photographic evidence indicates that these were added within a year or two of the WTC's initial construction following original plans. 6-28 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Figure 87.

July 2020 Cardno Evaluation of Significance 6-29 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 6.4.6.3 Evaluation of the WTC's Significance Modifications to the WTC building diminish its design and material significance when evaluating under Criteria Consideration G for resources that have achieved significance within the past 50 years. However, Cardno recommends the WTC as a whole is a contributing element to the historic district due to its historical significance to the development of the Weyerhaeuser Corporate Headquarters campus. As proposed by the design team in early site planning for the campus, the aesthetics for the WTC differ from that of the headquarters area and retain a prescribed buffer of trees that separate it from the Headquarters area. It also mirrors the Headquarters concept of a central building with six parking lots. On architectural merits alone, however, Cardno recommends that the WTC fails to achieve the standard of exceptional significance of the headquarters area, due in part to the WTC's diminished integrity. Weyerhaeuser Company altered or abandoned some of the original concepts and features over time, such as the unfinished cedar siding and landscaping. Cardno recommends that the WTC does possess exceptional historical significance as part of the 1970s development of the historic campus. The building, parking lots, and adjacent landscaping were envisioned and designed by the same team as the Headquarters Building and its integrated landscape. Its construction also accomplished the original goal of integrating corporate administration with research and development on a single campus. Finally, with its wooded landscaping adjacent to Weyerhaeuser Way South, part of the originally -conceived circulation road, the WTC contributes to the image projected by Weyerhaeuser Company in the 1970s as a corporation committed to forest management practices rather than the simple exploitation of natural resources. With this historical significance, the WTC contributes to the overall significance of the campus by representing the corporation's history in this second and final major stage of campus development during its recommended period of historical significance (1969 to 1979). 6.4.7 Rhododendron Species Botanical Garden, opened 1975 with continuous development thereafter (Map ID "O", Appendix B-1) The rhododendron garden is comprised of plantings accessed by a circulation network of gravel walking paths (Figure 89). The path network has changed over time to accommodate new plantings and structures, including a non -historic visitor center, plant -sale pavilion, and Rutherford Conservatory, which are the main buildings found within the garden (Figure 90). West of the garden itself, adjacent to Interstate 5, is a series of greenhouses and other buildings used to propagate plants (Figure 91). Records at the King County Assessor date a number of the buildings to 1974 and 1975 (Washington State Archives 2019). These 1970s buildings contribute to the garden's historical significance as the facilities where the collection was cared for and expanded from the outset of the garden's establishment. As the garden has evolved, it has lost integrity of design and materials, which detracts from its design significance. However, its historical associations with Weyerhaeuser Company are significant, making it a contributing feature to the district. As the corporation worked to shift its image away from simple exploitation of natural resources, the Rhododendron Species Botanical Garden provided the public with an outdoor amenity that was surrounded by an example of the corporation's managed forests. 6-30 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Figure 89.

These are contributing elements to the garden. 6.4.8 Project House 2, completed ca. 1969 (Map ID "P", Appendix B-1) Project House 2, also known as the "Glue House", is a two-story building set on a concrete foundation on a sloping site (Figure 92 and Figure 93). As a result, the building appears to be a single -story building from the roadway, which is on higher ground. Entrances face southeast and northwest. A tree buffer separates the building from the roadway. A curving driveway passes the southwest side of the building to provide direct access to the entrances on the southeast side. A small parking lot to the southwest is within close proximity to the northwest -side entrance. The building has the appearance of a single-family dwelling, with a side -gable roof clad in composite shingles. The roof has a complex profile, with the central portion projecting slightly above and out from the side ends. A single, brick chimney projects from the ridgeline of the projecting section. The deep eaves are boxed with light fixtures inset above the doors on the east and west elevations. Exterior cladding consists of vertical T1-11 in the gable ends and horizontal wood -product, clapboard panels with wide battens over the vertical junctures. A wood stringer provides definition between the two floors. Windows are vertical, wood -framed units combined in pairs and groups of three or four in varying sizes. Some units are casements, others are fixed. All entrances contain slab doors. The doors to the second story of the southeast elevation each contain a single, upper light. All fenestration has matching, unornamented, wood surrounds. The most prominent feature on the southeast elevation is a two-story porch, which has been altered from its original design to provide exterior stair access to the second floor. The porch is clad in clapboard. Aside from alterations to the porch, which were made in kind, Project House 2 retains integrity. It served as the campus's archives and offices throughout Weyerhaeuser Company's occupation of the site. Given its form as a residence and name given on original plans ("Research House 2"), Project House 2 appears to be associated with the corporation's history of building demonstration houses to test and display its products. Another example is the Weyerhaeuser Company's 1936 model home at 545 361" Avenue East 6-32 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus in the Madison Park neighborhood of Seattle, which was used to demonstrate the use of plywood in house construction (Seattle Sunday Times 1934:11). Additionally, in 1961, the company sponsored the construction of another "wood -research" house in Bellevue, Washington following two years of research into wood products (Seattle Times 1961:33).

Opinions of those who provided interviews during the course of this study were unanimous on the importance of views to the significance of this historic designed landscape (P. Walker, personal communication, May 22, 2019; M. Clausen, personal communication, May 1, 2019; B. McLaren, personal communication, April 24, 2019; J. Ochsner, personal communication, May 8, 2019; D. Streatfield, personal communication, May 24, 2019; and T. Way, personal communication, May 8, 2019). As noted by Mozingo, "The restored woodland edge enclosed the long valley view. Framed by forest, meadow, and wetland, the palatial vista from two adjoining highways particularly pleased George Weyerhaeuser" (2011:142). As described in the U.S. Department of Transportation (USDOT) report "Guidelines for the Visual Impact Assessment of Highway Projects," views are, by their nature, subjective (USDOT 2013). Given that a number of the critical views of the Weyerhaeuser Corporate Headquarters campus are experienced in cars, Cardno used the USDOT guidelines to define views as objectively as possible. Views were evaluated during field surveys in winter, spring, and summer to assess views during varying stages of tree cover and state of vegetation (Figure 94 and Figure 95). To evaluate views from the headquarters building, photographs were taken on each floor of the surrounding landscape in order to consider the perspective of the different heights (Figure 95 and Figure 96). Additional, desk -based analysis compared site photographs with topographical maps. Topographical maps were of particular use in estimating the limits of views from the headquarters building, where trees on higher ridges blocked views of the landscape beyond. 6-34 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Figure 94. Photograph of the pond taken in February 2019 from the eastern end of the headquarters building's fourth floor, facing north-northwest. To evaluate the views of stands of trees, they were identified as: managed woods (red outline), wooded buffers (blue outline), and borrowed views (yellow outline). These correspond to foreground, middle ground, and background views. Figure 95. Photograph of the pond taken in May 2019 from slightly east of the previous view on the fourth floor of the headquarters building, facing north-northwest. As in the previous image, the managed woods are outlined in red (included in foreground views), wooded buffers in blue (middle ground views), and borrowed views in yellow (background views). July 2020 Cardno Evaluation of Significance 6-35 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Figure 96. Photograph of the pond taken in June 2019, this time from the first floor of the headquarters building, facing north. Again, stands of trees are identified as the managed woods (red, foreground), wooded buffers (blue, middle ground), and borrowed views (yellow, background). The views recommended as critical to the significance of the recommended NRHP-eligible district are: > North and south from inside the headquarters building (Appendix B-2) — These views from all floors of the headquarters building reveal the character -defining pond and meadow as well as the surrounding landscape. Views are guided along a visual axis by the use of managed forests in the foreground and wooded buffers along the meadow in the middle ground and background. Topography plays a role in determining the terminus of these views. Borrowed views of the highways and trees beyond as well as occasional glimpses of Mt. Rainier are also features of these character -defining views; > The headquarters building (Appendix B-3 and B-4) — Following the same axis as described above, framed views of the headquarters building by drivers on Interstate 5, State Route 18, and the circulation road around the headquarters are also character -defining features of the historic district. Additional views of the headquarters for pedestrians that were part of the 1969 plan are those from the parking lots and informal path around the pond; and > The forest buffer as experienced by the driver from the circulation road (Appendix B-5) — While arguably less dramatic than the views to and from the headquarters building, the experience of the wooded buffers while driving around the headquarters circulation road emphasizes the evolving image of Weyerhaeuser at the time as a corporation in the business of managing forests. Because of their wooded setting, the driver's experience of crossing the meadows is all the more dramatic, allowing the eye to be drawn to the headquarters building. Although views are less tangible than the structural and landscape features at the headquarters, they are nonetheless recommended as contributing elements to the historic district due to their pivotal design significance. 6-36 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Regarding "borrowed views" of and across State Route 18 and Interstate 5, these have been excluded from the historic district boundary due to their location on and across state highways, which form a human -made boundary, as well as the challenge of determining their limits. However, these borrowed views are an important component of the background views from the headquarters building.

For example, the headquarters building, parking lots, parking lot landscaping, pond, managed woods, meadows, and circulation roads were designed as a single composition, which is part of what makes this designed landscape exceptional. Four buildings built before or during the recommended period of significance (1969 — 1979) and located within the boundary of the recommended -eligible historic district can be evaluated individually because they were not designed to be integrated within the headquarters campus landscape: > Former Puget Sound Power & Light Company Service Building; > Project House 1; > Project House 2; and > Former King County Fire District Number 22 Fire Station. July 2020 Cardno Evaluation of Significance 6-41 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Cardno recommends that three of these buildings meet the criteria for evaluation under the NHPA (36 CFR § 800.16) for individual NRHP eligibility as discussed below. Recommendations of individual eligibility for listing in the NRHP do not imply greater significance than NRHP eligibility as a historic district. 6.6.1 Former Puget Sound Power & Light Company Service Building (2835 South 344t" Street This former utility service building is one story tall set on a poured concrete foundation with an irregular footprint. The eastern end of the building holds offices while the western end is used for storage. The site is accessed off of Weyerhaeuser Road south of the headquarters via a tree -lined driveway. The building is surrounded by a concrete parking lot. The property is now under separate ownership from the rest of the area proposed as the Weyerhaeuser Corporate Headquarters Campus Historic District; as a result, only what was visible from the parking lot near the driveway was surveyed. The western end of the building has a covered loading dock that spans most of the north elevation surmounted by a flat roof with parapet. There are no windows on the visible elevations of this end of the building (north and west). Doors within the loading dock area were not accessible. The north elevation of the eastern end of the building is clad in patterned concrete block. The flat roof at this end has boxed eaves. A bank of seven metal -framed, floor -to -ceiling windows set in metal frames with transoms and mullions is located east of the pedestrian entrance. A metal -framed, canvas -wrapped, half -cylinder hood protects the entrance from rain. The door is a glazed, metal unit. Cardno recommends the Former Puget Sound Power & Light Company Service Building not eligible for listing the NRHP. Although it possesses integrity of location, setting, material, workmanship, and feeling, it fails to satisfy the four criteria of evaluation for NRHP listing as follows: > Criterion A: As a utilitarian utility building from its construction until 50 years ago, it has not been found to be associated with a significant event in our past; > Criterion B: It is also not associated with a person significant in history; > Criterion C: Due to its diminished integrity, it fails to embody the distinctive design characteristics, represent the master, possess high artistic values, or represent a significant collection of designed resources; and > Criterion D: The building is unlikely to reveal information important to history through further investigation. 6-42 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Figure 97.

The loading dock addition is located in the foreground. 6.6.2 Project House 1 (33636 30' Avenue South) This former single-family dwelling with two -car, detached garage was constructed in 1964 and acquired by Weyerhaeuser Company in 1988 per King County Assessor records (King County Assessor 2019). The house is a stepped, three-story building set on a concrete foundation on a sloping site (Figure 100, Figure 101, and Figure 102). Because of the combination of the stepped form and sloping site, it appears to be a two-story building when viewed from the front or rear of the site. The most prominent feature from the public right-of-way is the flat -roof, two -car garage, which obstructs views of the house. The main entrance to the house is located on the southeastern side, towards the rear of the building, accessed via a covered, poured concrete walkway. Both buildings have flat roofs with eaves. Their exteriors are clad in plywood panels in horizontal lap formation, with wide battens over the vertical junctures. Windows are a combination of wood -framed, picture windows mostly paired with single, aluminum casement units. The front entrance has a stained, wood, slab door with offset, full -height, reeded side lights, two to the left and one to the right. The rear of the house contains an open, second -story porch with exposed framing and stick balustrade. Below the porch is a ground floor, concrete patio. Both levels are accessed via a pair of stained wood, single -light, French doors. The fenestration to the garage is a single, two -car, painted plywood, up -and -over unit, and a single, slab, pedestrian door on the same elevation as the door to the dwelling. Project House 1 possesses integrity of location, setting, design, materials, workmanship, and feeling. It was converted for use as a meeting space by Weyerhaeuser Company, most likely after the period of significance. It, therefore, fails to possess integrity of association with the Weyerhaeuser Corporate Headquarters during the recommended period of significance. Cardno applied the NRHP criteria of evaluation to Project House 1 and recommends that it is eligible for listing in the NRHP under Criterion C based on the following: 6-44 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus > Criterion A: Having been acquired by Weyerhaeuser Company less than 50 years ago and having no significant associations with an event important in history, Project House 1 fails to meet this criterion for listing; > Criterion B: The building is not associated with a person significant in history. It is not recommended eligible for listing in the NRHP under this criterion; > Criterion C: Possessing all elements of historical integrity, Project House 1 embodies the distinctive characteristics of a stepped -level, Modernist dwelling featuring exterior plywood paneling. Cardno recommends the building eligible for individual listing in the NRHP under Criterion C; and > Criterion D: Because the potential significance of the resource is fully expressed by its above -ground construction, it is unlikely to reveal additional information important in our past. It has a local level of significance. Its recommended date of significance is 1964. Because the surrounding vegetation does not directly contribute to the significance under Criterion C, its recommended boundary is the footprint of the former dwelling and garage only. Figure 100.

Alterations to the porch on the southeast elevation have impacted the property's integrity of design and materials. The integrity of setting has also been negatively impacted by the change in orientation as a result of the loss of its original access road (32"d Avenue South) and construction of Weyerhaeuser Way South. Overall, the property possesses integrity of location, materials, workmanship, feeling, and association. Cardno applied the NRHP evaluation criteria to Project House 2 and recommends that it is eligible for listing in the NRHP under Criterion A based on the following analysis: > Criterion A: Project House 2 possesses sufficient integrity to represent Weyerhaeuser Company's historical practice of constructing demonstration houses to test and display its products. As a result, it is recommended eligible for listing in the NRHP under this criterion; > Criterion B: The building is not significantly associated with important historical persons. It fails to meet this criterion for listing in the NRHP; > Criterion C: In design terms, Project House 2 has diminished integrity and does not embody the distinctive characteristics of a type, period, or method of construction, represent the work of a master or exhibit high artistic value. It also does not represent an important entity whose individual components fail to possess distinction. The building is not recommended eligible for listing under Criterion C; and > Criterion D: It is unlikely to yield information important to history through archaeological investigation so is not recommended for listing under Criterion D. It has a local level of significance. Its recommended date of significance is 1969 and boundary is the footprint of the building only. Figure 103. Rear elevation of Project House 2, facing northwest. This was originally the front elevation. The porch has been significantly altered. July 2020 Cardno Evaluation of Significance 6-47 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus 6.6.4 King County Fire District Number 22 Fire Station (33663 Weyerhaeuser Way South) This former fire station was constructed in 1969 with the hose tower added in 1971. The tower is no longer extant. The single -story building is oriented to the north and has a depressed front -gable roof with extended east slope (Figure 104 and Figure 105). Rafter tails are exposed on the side elevations. The deep eaves are treated with fascia boards and boxed with drop siding. A pair of rafters is exposed just below the eaves. The building is set on a poured concrete foundation. The front exterior cladding is blond brick; the side and rear elevations are treated with concrete block. The front elevation is dominated by two garage doors and a single pedestrian door. The garage doors are paneled wood and glazed roller units. The slab front door is set in a steel frame that is shared with a fixed picture window. Side windows are horizontal, aluminum sliding units. The windows on the east elevation have window boxes supported by metal brackets. The paved rear yard is surrounded by a chain link fence and contains a number of non -historic utility buildings that support the work of the landscaping business that maintains the campus (Figure 106). Because the hose tower was added two years after original construction, its loss does not significantly affect its overall integrity. The former King County Fire District Number 22 Fire Station possesses integrity of location, design, materials, and workmanship. Recent alterations and the acquisition by Weyerhaeuser Company have negatively impacted its integrity of setting, feeling, and association. However, Cardno recommends that it possesses sufficient architectural integrity to be recommended eligible for listing in the NRHP under Criteria A and C as follows: > Criterion A: — The former fire station is associated with the historical development of South King Fire & Rescue following its establishment in 1944 as the population of the region expanded. It is recommended eligible for NRHP listing under this criterion; > Criterion B: The building is not associated with persons significant in our past. It is not recommended for listing under Criterion B; > Criterion C: The former fire station embodies the distinctive characteristics of the later phase of Northwest Modernism as applied to public buildings. As a result, it is recommended eligible for listing under Criterion C; and > Criterion D: The building is unlikely to reveal additional information important to history through further investigation and therefore, is not recommended eligible for listing in the NRHP under Criterion D. Cardno recommends that it has a local level of significance. Its recommended date of significance is 1969. Because all outbuildings were constructed less than 50 years ago, the recommended historic property boundary is the footprint of the building only. 6-48 Evaluation of Significance Cardno July 2020 Results of Built Environment Survey of Former Weyerhaeuser Corporate Headquarters Campus Figure 104.

Within the recommended boundaries of the historic district, the historic property possesses integrity of location, setting, design, materials, workmanship, feeling, and association. Cardno recommends the proposed historic district eligible for the NRHP under Criteria A and C for its associations with the introduction of the suburban corporate campus to the West Coast, its association with Weyerhaeuser Company's changing corporate image, and as an outstanding example of the integrated work of architect Edward Charles "Chuck" Bassett of Skidmore, Owings, and Merrill and Peter Walker of Sasaki, Walker and Associates. Because of the proposed historic district's exceptional historical and design significance, it is recommended eligible under Criteria Consideration G for resources that have achieved significance within the past 50 years. Its recommended period of significance is 1969 through 1979. In addition, three historic resources are recommended eligible for individual listing in the NRHP: Project House 1, Project House 2, and the Former King County Fire District Number 22 Fire House. Of these three properties, only Project House 2 is also recommended contributing to the Weyerhaeuser Corporate Headquarters campus historic district due to its construction and use by Weyerhaeuser Company during the district's recommended period of significance.
