Our high rise apartment building is located in a fairly dense urban area. The project team felt pretty confident that we could make ID level density. However, our site is proximate to coastline such that several marina moorage properties fall within the density radius. These properties are large SF with obviously no buildings on them. No building could ever actually occur, but they are parcels with SF that are identified in the County Assessor maps. Are we obliged to treat these parcels like parking lots and include them?
