/� / .-` Erosion Control One issue of construction is erosion control, Because there is little soil on the lot, erosion should be easily treated. On any boundary of the property that slopes downward to an adjacent property, an erosion control measure should be placed. This includes the back boundary and portions ofthe houndary on the left. ifyou were to face the property from the road. Several types of erosion control can be used. Contractors often install silt fences in cases like this. However, hecause silt fences require digging into the ground, which in this case is rock, it may be more practical to place straw bales and sand bags along the boundary. A third option is to build an earth barricr approximately 12" - 18" high to retain the silt-laden water until it can infiltrate into the ground. ess of the method, erosion during construction can be casily contained on-site. Grading The owner will have to obtain a gradi perrnit from the Department of Puhlic Works prior to gradi activities. The permit application would involve a grading plan p by a Ucenamd- professional civil en ce: lbc grading plan would ensure that the natural drainage pattern is niaintained as much as possible. Basically, the owner cannot change the location where storm water enters or leaves his or her property. The gentle siopes of the property and the smali amount ofstorm water that it generates should make drainage o relatively simple issue to settle. At a community meeting discussing this project, a neighbor offered aconcern that grading the property or placing an impervious surface such as concrete or asphalt on the property could result in groundwater hcing hrought to the immediate subsurface through some sort of
