BACKGROUND AND SUMMARY • The Ball Aerospace Control Cells Building was designed by Hobart Wagener and constructed in 1956 and added onto in 1960. • A condition of staff’s recommendation for Site Review approval for the redevelopment of the larger Ball Aerospace site is submission of landmark designation application for the 1956 Control Cells portion of the building and a portion of the property (excluding the 1960 addition). A landmark application was submitted on November 19th, 2021; the designation is pending and contingent upon Site Review approval of the development by the Planning Board. • Four other Hobart Wagener-designed buildings on the property, constructed between 1959 and 1962, have been approved by staff for demolition (HIS2021-00293). • On Nov. 9, 2021, the owner submitted a Landmark Alteration Certificate (LAC) application for the removal of the 1960 addition and restoration of the building. • On Nov. 24, the LDRC referred the application to the Landmarks Board for review. • Staff recommends that provided the stated conditions are met, the proposal will meet the criteria for a Landmark Alteration Certificate as per 9-11-18(a) & (b)(1)-(4) B.R.C. 1981 and be generally consistent the General Design Guidelines. PROPERTY DESCRIPTION Ball Aerospace & Technologies Boulder Campus at 1600 Commerce Ave. and 5001 Arapahoe Ave. is located on the north side of Arapahoe Avenue, between Commerce and Range streets in East Boulder. The property is not located in a potential historic district. Figure 1. Location Map, Ball Aerospace & Technologies Campus, 1600 Commerce St. and 5001 Arapahoe Ave. Figure 1. Aerial, Ball Aerospace & Technologies Campus, 1600 Commerce St. and 5001 Arapahoe Ave. Building Description – 1956 ADO/Control Cells Building The Ball Brothers Control Cells building was constructed in two phases. The original building was completed in 1956, and the addition on the west side of the building was completed in 1960. The Regional Modernist building is constructed of painted concrete block with an alternating pattern of projecting blocks. Stylistically, the building can best be described as Expressionistic in inspiration with its strong sculptural forms paired with non-traditional structural elements. The building was constructed in two phases: a square volume with a butterfly roof and a wing extending from the west elevation with an accordion roof form. The most distinctive characteristics of the building are the expressive roof forms, exposed skeletal structural systems, patterned concrete block and clerestory windows. Figure 3.

Building Description – 1960 Addition In 1960, Ball Brothers converted the use of the Control Cells Building from a laboratory to an administrative office. Hobart Wagener was commissioned to design an addition, which extends from the west elevation of the original building. The addition is stylistically similar, with concrete block with an alternating block pattern, clerestory windows, alternating roof forms and exposed skeletal structural systems. Where the original ADO/Control Cell building is a single story, the addition is two-stories due to the grade.

HISTORIC CONTEXT In the 1950s Boulder began marketing itself as the perfect place for “clean” industry (City of Boulder website, accessed May 9, 2008). Instead of relying on the land for products to process, Boulder looked for industries which focused on electrical, engineering, environmental, or computer science. 1 In 1949, Boulder successfully secured the establishment of the National Bureau of Standard’s (NBS) Central Radio Propagation Laboratory and the following decades saw the establishment of several public and private research institutions. The Chamber of Commerce bought an eighteen-acre tract [in East Boulder], called it the Boulder Industrial Park, and convinced Ball Brothers Research Corporation to be its first tenant (first building was completed by May 1956).2 Edmund F. Ball purchased Control Cells Inc. and founded the Ball Brothers Research Corp in 1956. Ball Brothers Research Corporation became Boulder’s largest employer outside of the university, with over 3,000 employees.3 O.E. “Pete” Bartoe, was the company’s first employee and worked as a seminal space craft designer. Bartoe, CU physicist David Stacey, and CU engineer Jim Jackson moved into the Control Cells building and started designing a new pointing control.4 R.C. “Merc” Mercure, joined the company in 1957 and became the company’s president. The company started out with orbiting solar observatories which were crucial in the development of the company. Mercure said, “We became very skilled at it [making instruments for space] and developed an enormous reputation among space scientists of the nation because we could take what they wanted to do and make instruments.”5 1 Bryant, Jennifer, and Carrie Schomig. “Historic Context and Survey of Post-World War II Residential Architecture Boulder, Colorado,” April 2010. https://www- static.bouldercolorado.gov/docs/Combined_Post_WWII_Residential_Survey,_2010-1- 201509031405.pdf?_ga=2.250775622.170951014.1608483712-1638280431.1606173491 2 Smith, Phyllis.

As the company grew, so did the Industrial Park. Hobart D. Wagener, a notable architect in Boulder and Colorado, was commissioned to design the buildings for Ball Brothers.6 Wagener’s design for the Control Cells building was realized in 1956 and is the earliest building on the site.7 A year later, it was converted into a research lab. Around 1960 it was converted into an administrative building. An addition also designed by Wagener was added in 1960. A series of “Tech” building (Tech I – Tech III) were constructed in 1959 after design by. Wagener Associates. A Boulder Daily Camera article from November 1959 captions a photo of the new Technical Building No. 1 with “Ball Brothers Research Corporation, a growing factor in U.S. 6 “Hobart D. Wagener,” Coronado Eagle & Journal | Coronado News | Coronado Island News, October 2005, http://www.coronadonewsca.com/obituaries/hobart-d-wagener/article_0486f2ba-aad6-554c-95c0- b9ed4d769269.html. 7 City of Boulder Historic Preservation Program, “History of Buildings, Ball Aerospace,” December 2020. space experiments, recently moved into this new building in Boulder Industrial Park … which is already proving inadequate.”8 The Tech Tower was constructed in 1962 and was another design by Hobart D. Wagener Associates and was featured in the 1966 book “Mountains, Mines & Mansions: An Architectural Guide to Colorado.” The Tech Tower served as additional research space, office and laboratory areas.9 Figure 13.

Hobart Wagener Hobart Wagener is one of Boulder’s most well-known and prolific Modernist architects. He graduated with honors from the University of Michigan School of Architecture and worked in the offices of Eggers and Higgens in New York City and Pietro Belluschi in Portland, Oregon before moving to Boulder in 1950. After working in the offices of James Hunter, he opened his own office in 1953 and practiced until retirement in 1985. He designed over 200 public and private buildings, including St. John's Episcopal Chapel, First Methodist Sanctuary, Midland Saving and Loan (the Atrium), Fairview High School, Presbyterian Manor Apartments, Fruehauf Garden Center and the First National Bank. Sixteen buildings were featured in architectural and professional publications; ten received national or regional awards from the American Institute of Architects (AIA). In 1971, “Hoby” was elected a Fellow in the AIA and in 1985 was recognized as the architect of the year with the AIA Colorado Honor Award. In 1995, Williams Village received an award as the outstanding building built in Colorado in the past 25 years. In 1998, the Colorado North Chapter of the AIA presented him the President's Award for practicing architecture significant to the professional development of a future generation of architects. Local Recognition of Buildings Designed by Wagener The 2000 Historic Context and Survey of Modern Architecture in Boulder, Colorado 1947-1977 identifies Wagener as an acknowledged master of local architecture. The survey identifies “the most important architects and sixty-six of the most significant buildings of the period.” The survey included 10 buildings designed by Wagener: 1. Midland Savings and Loan, 1300 Canyon, 1969 (Pending Landmark Designation Application) 2. Fire Station #2, 2225 Baseline Rd., 1958 3. Green Shield Office Building, 900 28th St., 1959 (individually landmarked) 4. LaBrot House, 819 6th St., 1954 (individually landmarked) 5. Central Fire Station, 2441 13th St., 1957 6.

CRITERIA FOR THE BOARD’S DECISION STANDARDS FOR LANDMARK ALTERATION CERTIFICATES, 9-11-18, B.R.C., 1981 (a) The Landmarks Board and the City Council shall not approve an application for a Landmark Alteration Certificate unless each such agency finds that the proposed work is consistent with the purposes of this chapter. (b) Neither the Landmarks Board nor the City Council shall approve a Landmark Alteration Certificate unless it meets the following conditions: 1. Does the proposed application preserve, enhance, or restore, and not damage or destroy the exterior architectural features of the landmark or the subject property within a historic district? Provided the stated conditions are met, staff finds the proposal will be generally consistent with the purposes of this chapter, in that the proposed removal of the 1960 addition and restoration of the 1956 Control Cells Building will not damage the historic character of the property. 2. Does the proposed application adversely affect the special character or special historic, architectural, or aesthetic interest or value of the landmark property? Provided the stated conditions are met, staff considers the removal of the 1960 addition and restoration of the 1956 Control Cells Building will not adversely affect the special character or special historic, architectural, and value of the property as the changes are generally consistent with the General Design Guidelines. 3. Is the architectural style, arrangement, texture, color, arrangement of color, and materials used on existing and proposed structures compatible with the character of the landmark property? Provided the stated conditions are met, staff considers that the materials proposed for the restoration of the 1956 Control Cells Building will be compatible with the landmark property. (c) In determining whether to approve a Landmark Alteration Certificate, the Landmarks Board shall consider the economic feasibility of alternatives, incorporation of energy-efficient design and enhanced access for the disabled. Specific information specific to economic feasibly of alternatives, incorporation or energy- efficiency design and enhance access for the disabled was not submitted with the application. The reuse of an existing building is inherently sustainable, and the rehabilitation of the building will need to meet the City’s energy code regulations and Section 106.5 helps ensure that any alterations needed to meet the energy will not detract from the historic character of the site. DESIGN GUIDELINE ANALYSIS The Historic Preservation Ordinance sets forth the standards the Landmarks Board must apply when reviewing a request for a Landmark Alteration Certificate (LAC). The Board has adopted the General Design Guidelines for Boulder’s Historic Districts and Individual Landmarks to help interpret the ordinance. Design guidelines are intended to be used as an aid to appropriate design and not as a checklist of items for compliance. SUMMARY As outlined in the General Design Guidelines, the Secretary of the Interior provides four approaches to responsible preservation practices (p22). “Restoration focuses on the retention of materials from the most significant time in a property's history, while permitting the removal of materials from other periods.” The Boulder Revise Code establishes the criteria for the approval of Landmark Alteration Certificates in Section 9-11-18, including: “The proposed work preserves, enhances, or restores and does not damage or destroy the exterior architectural features of the landmark or the subject property within an historic district.” Staff considers that the proposed removal of the west 1960 addition will restore the ADO/Control Cells Building to its original 1956 appearance and will retain materials from the most significant time in the property’s history, as the building was the very first building on the Ball Aerospace Campus and in the Boulder Industrial Park. While the 1960 addition was designed by Wagener and in keeping with the architectural language of the 1956 Control Cells Building, staff considers its removal to allow for the restoration of the very striking west (Commerce Street facing) glass-curtain wall of the original building. Likewise, staff is of the opinion that the small portion on the north side (rear) of the original Control Cells Building not a character-defining feature and its removal would not adversely affect the special character of the building. 2.4 Parking and Driveways •Restoration of circular drive based on historic photographs and drawings is consistent with design guidelines. 3.7 Windows and Doors •Windows preserved / proposed for replacement – details not submitted; resolve at the Ldrc. •New garage door opening on north elevation will not be detrimental to the historic character of the property as it is located on a tertiary elevation. Its installation will require the removal of two windows and a small portion of concrete block. Staff considers that the proposal to remove the 1960 addition and accurately restore the 1956 Control Cells Building and Site features is generally consistent with the Secretary of the Interior’s Standards for Restoration and the General Design Guidelines for Boulder’s Historic Landmarks, but that the Landmark Board’s approval be contingent upon details on all windows, doors, grading/hardscaping, and final paint colors being reviews and approved by the Landmark design review committee prior to application for a building permit. PUBLIC COMMENT Staff has received no public comment regarding this application. FINDINGS Staff recommends the Landmarks Board adopt the following findings: The Landmarks Board finds that the project meets the standards for issuance of a Landmark Alteration Certificate set forth in Section 9-11-18, “Standards for Landmark Alteration Certificate Applications,” B.R.C. 1981. In reaching this conclusion, the Board considers the information in the staff memorandum dated January 5, 2022, and the evidence provided to the Board at its January 5, 2022 meeting. Specifically, the Board finds, if the stated conditions are met, that: •The proposal will be generally consistent with the purposes of this chapter, in that the proposed restoration will not damage the historic character of the landmark property. •The proposed restoration will not adversely affect the special character or special historic, architectural, and value of the landmark property as they are generally consistent with the General Design Guidelines and Section 9-11-18(b)(3) of the Boulder Revised Code 1981.
