The Port of Hood River Commission approved a memorandum of understanding with Pfriem Family Brewers to allow the company to do a series of improvement projects to the Halyard Building on the waterfront that would increase its brewing capacity.  A three-phased multi-year construction schedule calls for internal improvements, additional utilities, and more equipment inside and outside of the building.  But the changes and ensuing staff increases will trigger a need for a City-required 26 additional parking spaces.  Port Executive Director Michael McElwee says the agency will help find those spaces.  Pfriem is the only tenant in the Halyard Building.
