231 5 // TREATMENT RECOMMENDATIONS Landscape Rehabilitation Tasks and Prioritization The following section provides specific treatment tasks associated with rehabilitation of the Darwin D. Martin House cultural landscape. These recommended treatment tasks have been developed to provide guidance in implementing the primary treatment goal. Site-wide guidelines should be followed when planning for and completing these tasks. To help organize these tasks they have been organized by landscape unit, as defined within the introduction of the CLR. Furthermore, each treatment task has been prioritized (high, medium, low) based on factors such as feasibility, overall influence on the rehabilitation treatment or interpretive goals of the MHRC. The rehabilitation tasks also identify the features of the landscape that may be missing from the unit but are not recommended to be replaced due to the current use or program purposes. In some instances these tasks may not fully meet the priority recommendations noted within the site-wide guidelines. Generally these represent conflicts with other, higher priority site-wide recommendations such as the protection and preservation of other historic assets. The Jewett Frontage What’s not being replaced in the Jewett Frontage: • Western side of driveway American elm should not be replaced due to the maturity of the historic adjacent beech tree. • The driveway apron at Jewett Parkway should remain in its current rehabilitated condition (concrete) to mitigate potential damage from intermittent driveway use or city right-of-way snow removal. It is not recommended that the surface paving treatment be changed to chip-seal for these reasons. • The street lighting should remain consistent throughout the neighborhood and not altered in front of the Martin House for interpretive purposes. If in the future the street lighting will be replaced by the City or the neighborhood, then an appropriate Olmsted-period fixture should be selected based on a neighborhood wide lighting plan. Jewett Frontage Treatment Tasks 1. Preserve Beech: Efforts should be made to preserve and maintain the health of the extant purple leaved cultivar of European Beech (Fagus sylvatica, atropurpurea group). This may include enhanced monitoring or future preventative treatments for Phytophthora Bleeding Canker, and/ or adaptations of landscape rehabilitation intent of nearby garden spaces to maintain health of root system. A certified arborist should be contracted on an annual basis to inspect (and potentially treat, if warranted) the tree. Should the beech be removed or reach the end of its lifecycle, this portion of the landscape unit should be reassessed for appropriate treatment. 2. Remove Non-Contributing Street Trees: Remove non-contributing <10” dbh purple leave cultivar of Norway maple (Acer platanoides ‘Crimson King’). 3. Remove Miscanthus: Remove non- contributing miscanthus ornamental grasses from front raised planter. 4. Plant Street Trees: Plant American elm street trees (or appropriate replacement, per the planting guidelines) along the Jewett Parkway right-of-way (treelawn). Spacing of trees should approach the density of the historic condition while promoting long-term health of root systems or accommodating known obstacles such as street lights or utilities. Street trees should be located and installed concurrently with all adjacent-unit street trees. 5. Plant East Driveway Elm Tree: Plant an American elm tree (or appropriate replacement)) in the location documented on the east side of driveway.
