1. Reexamine the 2007 Master Plan and the analyses that informed it, and reimagine within a more sustainable context (fiscally & environmentally).

2. Preserve and elevate the cultural resources reflecting the Arboretum’s history, the agricultural context of the institute and the land, and the diverse landscapes of the Mt. Hamilton site.

3. Bring cohesion to the visitor experience by clarifying circulation and way-finding.

4. Acknowledge and embrace community connections, by increasing accessibility and supporting District alternative transportation plans.

5. Develop a Master Plan Update that will be implemented mostly through small, incremental changes, while allowing for strategic but often stochastic major investments.

RECOMMENDATIONS AS A SCIENTIFIC INSTITUTION 1. Renovate the greenhouse complex to provide state of the art facilities to serve the research and horticultural needs of the Arboretum 2.

Build a new maintenance building to provide for the increased maintenance requirements that will come from additional Arboretum Development 4. Enlarge the area devoted to research plots to 35 acres and increase the area devoted to collections of plants for the preservation of genetic diversity 5. Develop an efficient composting and staging facility

RECOMMENDATIONS SERVING THE COMMUNITY 1. Build a new main entrance to Bladensburg Road that is worthy of a major public institution. The corollary to this is to close all the other entrances to the public. This entrance should be as attractive as the rest of the Arboretum experience. 2. Create a core pedestrian precinct around the ellipse linking the Visitor’s Center, Azalea Collections, herb Garden, Bonsai and Penjing Museum, Fern Valley, and the Capitol Columns supplemented by new displays 3. Create a perennial display within the core to further enhance the core and provide popular appeal. 4. Create an area which engages families and educates and enchants the next generation of Arboretum supporters 5. Simplify the circulation to create a series of loops for visitors to tour the grounds. 6. Renovate and modernize the existing infrastructure 7. Create a comprehensive introduction of the USNA on the www which includes virtual tour

Build a visitor center to serve as the gateway to the site and provide facilities to educate the public about the world of plants 3. Build a garden about the Origin of Cultivated Plants to introduce the public to the origin and evolution of economically important plants. 4. Provide a network of educational and visitor facilities across the site including interpretive centers, restrooms, limited satellite parking and places to get on and off the tram.

REED HILDERBRAND USNA MP UPDATE JULY 2, 2020 PAGE 40 APPENDIX APPENDIX: SUMMARY OF SITE DEVELOPMENT Summary

DEVELOPMENT PATTERNS Long before the establishment of this site as the US National Arboretum, it reflected an agricultural heritage that began in the mid-1800’s. The farmsteads of Abercrombie, Colonel Hickey, Dr. Palmer and Corcoran subdivided this landscape into a patchwork of fields, orchards and woodlands. Historical maps suggest that some site features, such as the Ellipse Meadow, have existed in place for nearly 150 years. The 1933 aerial photograph still reflects this patchwork even as new developments such as the New York Avenue Brickworks and the neighborhood north of R street begin to grow around at the periphery of the Arboretum. The 1937 Preliminary Road study by the National Capital Parks in collaboration with the National Capital Park and Planning Commission suggested a system of loop roads that circumnavigate the topography and ecology of the landscape. Portions of this proposed road system have been in place since 1951, such as the loops at Mt. Hamilton and Hickey Hill, while the loop at the Ellipse meadow had been truncated. Entrances exist on R Street and M Street. Research nurseries occupied the open space of former agricultural fields prior to opening to the public in 1959. By 1988, the public offerings of the Administration Building (1962-63), the National Herb Garden (1980), and the Japanese Pavilion (1972) within the Bonsai Museum had been constructed within the core, and the site of the 1933 AERIAL PHOTOGRAPH OF THE US NATIONAL ARBORETUM SITE Capitol Columns appears to have been under construction. The majority of the vehicular circulation that exists today had been implemented by then, including the boulevard and parking area at the M street gate and the New York Avenue entrance. By 2017 the majority of public offerings existed within the Core of the Arboretum. Today their spatial relationship is fragmented, with public offerings disconnected from each other, and devoid of the larger spatial expansiveness of the Arboretum.

IDENTITY The Arboretum is defined by two primary hills, Mt. Hamilton to the west, and Hickey Hill to the east, that are divided by a strong ravine of Hickey Creek that drains to the Anacostia. There is over two hundred feet of elevation change within the Arboretum, offering different ecosystems and plant communities. Relating directly to topography, the Arboretum could be distilled into four primary zones of character: dendritic ravines, wooded hills, rolling meadows and agrarian fields. These four zones represent the heritage of this landscape for the past 200 years and establish a pastoral identity for the Arboretum.

ARRIVAL, CIRCULATION AND PARKING The current system of circulation lacks hierarchy and clarity, a form that appears to be a result of accretion and varied incomplete master plan efforts that shifted priorities. The current entrance on R Street at the Arboretum disrupts a pedestrian neighborhood and would be more appropriate if off a major road as indicated in the previous master plan. Former entrance ideas at New York Avenue and M Street remain with vast remnant parking lots that ARBORETUM CORE no longer serve the current needs. The two-way drive system represents The Arboretum Core offers the majority of concentrated visitor offerings. nearly 10-miles of roadway, and lacks hierarchy and clarity, complicating These offerings are adjacent but not systemically organized, resulting in a wayfinding for the visitor. series of fragmented internal rooms. In an effort to connect them, and as a response to visitor interest, large plantings of resource-intensive perennial Pedestrian dedicated circulation is limited to areas in the core and collections gardens have been established that do not contribute to the larger Arboretum on the east edge of the Arboretum, forcing pedestrians to walk amongst landscape. vehicles to connect between the two sides of the arboretum. The large void of dedicated pedestrian circulation in the Arboretum correlates to a large void The Core also exhibits a concentration of the scientific research facilities in the collections. including the greenhouses, poly-houses, and nursery/research fields north of the Administration Building.
