During her inaugural address on Monday, Mayor Donna D. Holaday announced that Newburyport has been named a Coast Guard City. To date, the designation has been given to 14 communities across the country, from Rockland, Maine, to Eureka, Calif. In 1998, Congress enacted a law enabling recognition of communities that make “special efforts to acknowledge the professional work of the Coast Guard men and women assigned to its area.” Newburyport was the birthplace of the Coast Guard in 1791, as noted in a document signed by President Lyndon B. Johnson. The document is currently part of the collection of the Custom House Maritime Museum in Newburyport. Local officials are planning a formal celebration of the new distinction on Aug. 4, the date the Coast Guard was founded.
