The Hood River City Council approved an amendment to the municipal sign code clarifying that feather signs and similar signs that are supported by a pole and designed to flutter in the wind are prohibited.  City Codes Enforcement Officer Marty Morgan told the Council the code does not specifically specify these types of banners as prohibited under the sign ordinance.  City Manager Abigail Elder explained there is a safety issue with the fluttering flags, and there is an aesthetic concern as well.  City Attorney Dan Kearns also noted recently a business that had one felt they were allowed in the sign code, when it had been assumed over the years it was not.  The Council passed the amendment unanimously, and it will go into effect in 30 days.
