235 5 // TREATMENT RECOMMENDATIONS mimics the visual and spatial qualities as documented in the Period of Significance. The composition should have design relationship with both the Griffin Shrub Border and the Barton Front Yard planting rehabilitations. The Summit Terrace What’s not being replaced in the Summit Terrace: • Modifying the Summit Terrace opening to its Dorothy Martin wedding date condition is not recommended. The original design intent was an enclosed room and it was present this way until 1923, where it was only opened due to an event. The MHRC feels this event can best be interpreted through other means. The Summit Terrace Treatment Tasks 1. Trellis Wire Panels: Design and install trellis wire panels that replicate the appearance, form, size, detailing, and overall quantity of the trellis wire panels along the pergola using available documentation. For interpretive purposes, if deemed necessary for maintenance or longevity, it is suitable to vary the trellis design based on whether or not the trellis is intended to support plant material or intended as a reconstructed visual / interpretive element. 2. Plant Vines Along Pergola: Vine growth should be established on approximately 40-50% of the eastern pergola façade’s trellis wire. Vine species should consist of both wisteria and clematis and follow the plant selection guidelines. If possible, every effort should be made to propagate and utilize plant material from preserved historic vine specimens that have been transplanted outside of the historic core. 3. Accommodate Pedestrian Traffic on Turf Areas: Design and install specialty or reinforced turf profile that provides access from the conservatory doors to plant collections and the Summit Terrace steps. The intervention should mimic the look and feel of traditional turf lawn and be designed to accommodate limited daily pedestrian traffic. Where diamond shaped paver units are being replaced along the route, the reinforcing should be supplemental around the pavers. 4. Building Vine Wire System: Design and install a supplemental trellis wire system (independent of the recreated historic wire panels) that can accommodate growth over portions of the pergola roof and on masonry portions of the main house near the Summit Terrace and Floricycle. The system should follow vine cover guidelines. 5. Plant the Summit Terrace Area: Design and plant a predominantly herbaceous perennial composition on the Summit Terrace that is representative of the visual and spatial relationships, habit, texture, color, bloom, fragrance and scale of the vegetation present during the Period of Significance. The planting composition should reflect the general character of an English border garden and be fully distinguishable from naturalistic plantings closer to the boundaries of the historic property. Woody shrub material should be restricted in quantity to an amount that helps achieve a practical level of maintenance burden and does not significantly alter the intended visual character. Woody plant material should be limited to the peripheries of the terrace (the north and south ends). 6. Plant Elm Tree at South End of Terrace: Plant an American elm tree (or appropriate replacement, per the planting guidelines) in the location documented at the south end of the Summit Terrace. The final precise location should be determined concurrently with the design of the adjacent planting compositions. 7. Plant Cast Urn: Urns should be planted with seasonal annuals and perennials or other interpretive plants from the section list for urns. The habit and character of plants in urns should reflect, as much as possible, that seen in the limited photographic documentation. 8. Plant Ornamental Shrub Specimens: Design and plant a selection of ornamental H H H H H H H M The Summit Terrace
