West elevation of retaining wall & drains

Sketch plan drawing showing a west elevation view of June, 2010 installation of a stone-paved spillway, drains, and masonry retaining structures along the DeTurk House details west eaves wall foundation. [SEE DTR09FN7--1001.01.236 for discussion of the function of this installation in controlling and redistributing roof runoff and ground-surface water incursion, both of which frequently and progressively degraded the foundation mortar and wooden window framing in this west wall; see also, in same record, comments on the establishment and restoration of the early grade [now paved in stone] along this wall]. Also see DTR09FN7--1001.01.236, DTR09FN9--1001.01.238, and DTR09FN10--1001.01.239 for alternate plan drawings of this installation. See DTR09PH134--1001.01.230 for photographs of this installation.
