PORTLAND — Portland City Council wants the U.S. Postal Service to preserve an island community’s post office, which is on the list for possible closure.

In a unanimous vote Monday, the council said it would tell the Postal Service that the Cliff Island post office is a key part of island life and that its elimination would mean a three-hour round trip by ferry for residents who need to mail out packages.

Cliff Island is about 10 miles off the mainland.

WCSH-TV reports that the postal service has suggested contracting with a business to sell stamps and send packages if the Cliff Island branch is closed.

Last month, the financially troubled Postal Service said it was considering closing 1 in 10 of its retail outlets to save money.
