Roger meets landscape designer Tim Lee to see how the small stream in the backyard affects all other areas of the yard, including a patch of grass that has to be returned to the wild, and a stand of trees out front that can now be removed after careful consideration by the Conservation Commission. Before the trees come down, Roger shows Kevin the valuable shade plants that could be damaged in the process, so they’re relocated to a new bed in the side yard to provide screening from the neighboring house. Tom and Kevin cut away a five-foot section of wall to connect the new kitchen to the old great room. Richard shows Kevin two common rough plumbing conditions in the kitchen: a main sink that has a traditional drain and vent configuration, and an island prep sink, which requires a bow vent in order to work properly. Kevin meets building inspector Fred Lonardo to learn how a GC can call for a 'partial framing inspection' to keep progress moving on a job, as in the case with our front porch. Arborist John Marquis shows Roger the proper preparation, safety precautions, and procedures for doing a 'take down' of the 12 trees in the front yard.
