overall site plan that shows all phases, Phases 1, 2, 3, and 4 on one map. Indicate on the
map the outline of each Phase, all jurisdictional waterbodies, and the proposed impact
areas for each phase.
2. On Figure 2, "Concept Plan with Missing Wetland Areas Redelineated", it appears that
the site layout for Phase 1 is different than that provided in September 2016 and
different than the portion of Phase 1 shown on the large map identified as "Overall Lot

Redeli,neated", including BMP1 impacting an intermittent stream, Barn Door
Drive impacting a wetland, and Farm House Drive impacting a
stream/jursdicitonal pond/wetland area. If this is the layout proposed,
enumerate each of these additional impact areas and include impact maps for
each proposed impact area. Impact maps should be at a scale of no smaller than
1" = 50' with topographic contours shown. Please include cross section details
for any proposed culverts.
