STV PROJECT NUMBER 30-19702 Revised April 11, 2019 CONCEPT PRELIMINARY STUDY PERIMETER FENCE REPLACEMENT AT THE U.S. NATIONAL ARBORETUM

The U.S. Department of Agriculture (USDA) selected STV to design the replacement of approximately 2.4 miles of the existing perimeter fencing and gates. The existing fencing and gates are in various states of disrepair and are not consistent in appearance and design due to various sections being installed at later dates from the original fencing installed in the 1960s. Portion of the existing fence, mainly along New York Avenue are located outside USNA property and it is the intent to relocate those sections of fencing onto USNA property. Also, USNA is experiencing deer entering the Property and destroying specimen plantings throughout the year, and fawns being trapped between the pickets. The project proposes to install new fencing that maintains a consistent height of 8’-0” and picket spacing set to a maximum of 4” on center. Studies have indicated that fencing of 8 feet have reduced deer infestation as much as 90%. Due to the nature of the operation of the Arboretum , better perimeter controls are warranted to help maintain the specimen plantings within the property. Therefore, the intent of this project is to provide a consistent look for the perimeter fence, install new gates at the entrances, and provide better perimeter controls to prevent deer from entering the facility. The U.S. National Arboretum (USNA) established in 1927 by an act of Congress, is located in northeast Washington D.C., and consists of an approximate area of 451 acres. The USNA along with being a living museum and park, is also a U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) research and education facility. The limits of the USNA property is bound by New York Avenue NE (Route 50) to the north, Anacostia River to the east, Langston Golf Course to the southeast and south, M Street NE and private properties to the south, Bladensburg Road NE to the west and R Street NE and private properties to the northwest. Refer to Figure 1 for the Visitor’s Map below.

RE: Management Summary of research undertaken in support of perimeter fence replacement United States National Arboretum, Washington, D.C.

Consistent with our contract with STV executed on October 29, 2018, Gray & Pape has undertaken historical research and on-site investigation to determine the history of the existing perimeter fences at the United States National Arboretum (USNA) in support of the proposed replacement project. This Management Summary presents the results of that research in support of the review of the project by the National Capital Planning Commission (NCPC), U.S. Commission of Fine Arts (CFA), and the District of Columbia Historic Preservation Office (DCHPO).

On-Site Investigation

According to the boundary survey conducted by STV in 2018, the USNA property is currently 451 acres, comprised of the core 412-acre property assembled by 1949 (Figure 1), and the approximately 39-acre assemblage of parcels at the Page 2

northwest corner of the USNA that includes the United Brick Corporation parcel acquired by the USNA in 1977.

On October 16, 2018, Gray & Pape walked the length of the existing perimeter fence for the purpose of observation and recordation, and to identify the nature and locations of various segments. Gray & Pape walked the full length of the fence from the former M Street Entrance west to Bladensburg Road, north on Bladensburg Road to R Street, east on R Street to the R Street Entrance, northeast along Hickey Lane to the densely forested area northwest of the greenhouses, and the full length from the northwest corner of the USNA property on New York Avenue to the Conifer Road gate at the northeast corner of the USNA property and adjacent to the Washington Times Building. Because of the difficulty of traversing the dense vegetation, Gray & Pape did not observe the fence from Hickey Lane to New York Avenue between the residential neighborhood to the west of the USNA and the USNA. Gray & Pape only partially observed the fence along the Anacostia River side of the USNA based upon the understanding that the existing chain link fence would remain intact and no work was proposed as part of the project.

Documentary Research

Gray & Pape conducted research on the history and physical development of the USNA property to gain an understanding of the events and land use patterns relevant to the property boundaries, the gates, and the perimeter fence. In so doing, Gray & Pape confirmed that the USNA currently is distinguished with two historic designations, both of which have associated regulatory requirements that apply to the current project.

 The “National Arboretum” was designated as a D.C. Landmark in 1968. The boundaries of the property are not shown in the D.C. Inventory of Historic Sites, but the entry notes that the property is “more than 400 acres.”

 The “United States National Arboretum” was listed in the National Register of Historic Places (NRHP) in 1973. The 412-acre boundaries of the parcel as shown on the map are generally consistent with the current parcel boundaries, except for the exclusion of the former United Brick Corporation property on the south side of New York Avenue, since acquired by the USNA.

In addition to reviewing the NRHP nomination, Gray & Pape identified useful information in the following documentary sources for relevant information:

Page 3

 Written and photographic historical documentation associated with the United Brick Corporation property, which is a D.C. Landmark, is listed in the NRHP, and was recorded by the Historic American Engineering Record (HABS) in 1983. This documentation provided information regarding the segment of the New York Avenue fencing in the area of the brickyard.

 The Washington Post historical database, available online through ProQuest. Articles reviewed provided information on the original establishment of the USNA and the struggle to appropriately fund and develop the property, resulting in limited public access until the 1950s.

 The History and Development of the National Arboretum, by Charles A. Goodrum, 1950, available online through the HathiTrust. Provided written and photographic information on physical improvements on the landscape immediately prior to the opening of the property to the public.

 The Historical Society of Washington, D.C. online image catalogue. Contained several photographs of the area around the USNA from the mid-20th century, showing the condition of the grounds and existing fencing prior to what is there now.

 The Library of Congress and U.S. Geological Survey online map collections. Key maps included the 1887 G.M. Hopkins Map, 1922 and 1928 aerial mosaics, and 1945, 1951, 1956, 1957, and 1965 USGS topographic maps.

 One additional useful map, the 1913 Baist real estate map, was available online on the “Bygone Brookland” blog, along with information on the property prior to the establishment of the USNA in 1927.

This research supplemented the architectural drawings obtained by STV from Kevin Tunison of the USNA that pertain to the construction and alteration of the USNA gates and perimeter fencing at various stages. These drawings provide relatively firm dates for the most significant of the gates and fencing currently extant at the USNA.

Brief History

Research revealed that although the USNA was established by an Act of Congress in 1927, it was not until the late 1950s that the property began to resemble what it is today. The first 189 acres were acquired in 1928, followed by another 196 acres in 1934, and additional parcels in 1938 and 1949 to bring the total to 412. Although the USNA has acquired additional parcels since then, most notably, the former United Brick Corporation property on the south side of New York Avenue,

Page 4

those parcels have remained outside of the cohesive 412-acre property that was planned, improved, and open to the public in the mid-20th century.

The Arboretum was first opened to the public in 1949, but multiple sources indicate that access was limited to the Spring months or by appointment, and to a 60-acre area until 1959. Most of the buildings and landscape features that characterize the property today were planned and built in the 20-year period from 1947, when preparation of the 1947-1948 master plan began, and 1967, when the New York Avenue Springhouse Road and Conifer Road gates and the extant ornamental fencing between them were completed. This includes:

 1947 – First major permanent planting (azaleas) on the south slope of Mount Hamilton.

 1948, 1949 – Additional property acquired.

 1949-1958 – Construction of permanent road system.

 1949 – Garden Club of America donates funding for plantings between Hickey Hill and the Anacostia River.

 1952 – Dogwood area dedicated.

 1954 – Baltimore-Washington Parkway is completed and open to traffic. New York Avenue extension, which defined the north boundary of the USNA, completed by this time.

 1959 – USNA opens to the public year-round.

 1960 – Entrance gates at Bladensburg Road, R Street, and New York Avenue (Conifer Road) constructed (Figure 2).

 1962 – Five greenhouses completed on Hickey Lane.

 1964 – Administration & Research Building dedicated. M Street entrance gate complete by this time.

 1967 – New York Avenue Springhouse Road entrance gate completed. Construction of first segment of fence hereafter described as “Type A” completed.

Fence Type A

Research revealed that prior to the construction of the first set of entrance gates in 1960, a chain link fence enclosed the USNA property. The replacement of chain link fence with a more permanent, aesthetically pleasing fence consistent with the use of the property was planned by 1967 and possibly as early as 1960. Drawings from 1967 in the collection of the USNA show the New York Avenue entrance gates (Springhouse Road and Conifer Road) with a new fence between them. This steel fence is shown as having diagonally-set, bullet-nosed (rounded) steel pickets and I-beam posts capped with urn finials, the latter feature with a note that “a stock modern pattern of equal size will be selected.” This is consistent with the existing fence, Type A, which has a ball finial capping the posts (Figures 3 through 5).

Although the 1960 drawings for the Bladensburg Road, R Street, and New York Avenue Conifer Road entrance gates do not specifically show a freestanding Type A perimeter fence, they do show a similar fence (extant) with diagonally-set, bullet- nosed steel pickets along the top of the curved fieldstone walls flanking the gates. This suggests that the Type A perimeter fence design intentionally copied the M Street entrance gate.

By 1967 all the main entrance gates were completed, including the Bladensburg Road gate, the R Street gate, the New York Avenue Springhouse and Conifer Roads gates, and the M Street gate, and at least one segment of the Type A perimeter fence on New York Avenue.

Drawings in the collection of the USNA indicate that the extant segments of Type A fence along M Street, Bladensburg Road, and R Street were planned in 1982. The use of the same fence design is clearly an intentional effort to maintain consistency. By this time the M Street entrance gate was no longer in use, as shown in a 1979 aerial photograph of the USNA submitted to NCPC, and as reflected in the fact that the Type A perimeter fence constructed in 1982 runs south of and cuts off the M Street entrance gate.

A segment of the Type A fence was also was recorded at the northwest corner of the Arboretum property, running south from New York Avenue. This area was not part of the USNA until the United Brick Corporation property was acquired in 1977, and documentary photographs of the brickyard taken in 1977 and 1983 show a chain-link fence along New York Avenue.

Despite the apparent range in construction dates, all segments of the Type A fence were observed to be the same in material, design, and method of construction.

Page 6

An approximately 830-foot segment of the Type A fence on Bladensburg Road is presumed to have been removed and replaced with the existing chain link following widening and improvements to the road in 2004.

Fence Type B

A second type of perimeter fence, hereafter referred to as “Type B” in this summary, is located along New York Avenue between the northwest corner of the USNA property and the New York Avenue Springhouse Road entrance gate. While the Type B fence is similar, it is distinguished from the Type A fence by the hollow steel posts capped by spear finials and the perpendicular-set, flat-nosed pickets (Figures 6 and 7).

This Type B segment is shown as extant on 1990 project drawings for the construction of a parking lot between the United Brick Corporation buildings and the maintenance buildings, and the reconfiguration of the adjacent New York Avenue entrance gate (Figure 2, Gate 4). The ornate sandstone pillars that now support the gate at this location were brought to the USNA from storage at Fort Totten and placed as part of this project. The pillars are believed to have been part of the perimeter fence that encircled the original Capital building designed by Charles Bullfinch.

A small section of the Type B fence between Hickey Run and the United Brick Corporation buildings has been replaced in recent years. This is likely related to improvements made by WASA to Hickey Run.

Analysis

The NRHP nomination form for the National Arboretum does not directly address the period of significance for the property, and only enters the original date of establishment in this field of the form. The nomination form includes events related to the development of the property through the 1950s. Taking the nomination form as a point of departure, and considering additional research conducted for this study, Gray & Pape would recommend that a period of significance be considered through at least 1967 to encompass the period in which the Arboretum took on the configuration that it has today. Accordingly, all the fieldstone entrance gates from 1960-1967 would be contributing resources to the NRHP property. Because of the continuity of material, design, and construction in the Type A fence, despite the multiple periods of installation, Gray & Pape would recommend consideration of all segments as contributing resources to the NRHP property.
