The Port of Hood River Commission will hold its fall planning session on Tuesday.  A number of topics will be discussed, including the phase of planning for a new Interstate Bridge that will come after the draft EIS process, the next opportunities for development of properties in the waterfront area and at the Lower Mill site, and what the Port would look like as an agency after a new bridge is constructed.  Port Executive Director Michael McElwee says no matter how a new bridge comes about and who manages it, the Port will face change.  The planning session will start at noon Tuesday at the Port’s Marina Center conference room.
