The purpose of this revision is to primarily show the adjustments to the grading adjacent to the commercial property to the west, The Village Green, so that the wall height is reduced significantly. The two owners have an agreement to allow grading onto the adjacent property for this purpose. See attached documents. The yard drains have been coordinated with the plans as well for buildings along the south and western edge of the property. The sanitary sewer system has been extended between units 21 and 22 to collect the waste from The Village Green. In addition there have been several utility conflicts that are being addressed. The first is the Dominion Virginia Power, DVP, switch that is located at the intersection of Hydraulic and Inglewood. The switch was designed to be raised during construction to meet the proposed grades. DVP is reluctant to do so and has agreed to the addition of a wall so that the grades can remain around the switch area. Additional drainage structures have been added to accommodate this change. The other utility conflict is with the DVP concrete duct-bank that runs along Inglewood Drive. Proposed storm and water lines have been adjusted to avoid the existing duct- bank.
