Overhanging branches, northeast corner, Kingscote.
• Trim back overhangign branches; monitor roots to make sure they are not invading or disrupting the foundation.
Moss on roof, north elevation, carriage house, Kingscote.
• Cleanoff the moss; trim tree branches that are contributing to this growth.
Front drive, with pool to the right (west), above the basement, Marble House.
• Inspect the condition of all artificiat and natural pools to make sure theer is no seepage of water into the building.
East elevation, south corner, Green Animals.
• Minimize or elimate perimeter plantings and seek means to increase the exposure of the foundation and positive pitch away from the house.
Carriage House, Kingscote.
• The entire structure is at grade, creating complex, damaging conditions for the framing, whcih is being affected by insect damage and fungal rot. Correct these conditions.
North elevation and grade, Green Animals.
• Mimimize delivery of water onto lawn near porch. Increase pitch away from building.
Gravel drive, entry, Isaac Bell House.
• Reduce transport of gravel into house (with its wood flooring) by adding grates at entrance.
Drive, Château sur Mer.


Poor pitch of grade around perimeter of some houses is promoting ingress of water.

Inadequate exposure of foundations contribute to splashback and migration of moisture, which contributes to deterioration of wood and masonry.

Trees and shrubs near house are contributing to moisture-related damage on the exterior and interior and physical damage caused by branches.


Coordinate the preservation of the buildings and landscapes in such a manner that the presence of foundation plantings, nearby trees, negative grade (slope), and application of fertilizers are reduced without compromising the intergrity of the sites and their landscapes.

Grade and pitch along the perimeter, making sure that there is a positive slope away from that structures allowing for distribution of surcharge water, and that there is at least nine inches between the grade and any wood framing.

Prune trees and shrubs, making sure that there are not overhanging branches, trees whose roots may invade exterior pipework, or shrubs whose proximity to the perimeter may contribute to or hide insects, rot and other deterioration.

Monitor subsurface conditions, including soils and their effect on hydrostatic pressure; the introduction of water into spaces below grade; the location and condition of utilites; and any potential cultural material (archaeological finds).

Document and assess macro- and micro-environmental conditions and their pertinence to risk management and buildings.
