Wyandotte, Riverview Post Offices Latest Victim Of Budget Cuts (UPDATE)

Wyandotte's Post Office has become the latest casualty of cuts to the nation's postal service. The office which has operated since 1855, is scheduled to close in June of next year.

"Not having a satellite office in this city would be devastating," Wyandotte Mayor Joseph Peterson said as Monday's City Council Meeting, Patch reports. He urged residents to write letters in protest of the move.

Postmaster Michael Taurence "confirmed the closure plans, but said nothing is written in stone," according to Patch.

The Riverview post office is also set to close. Mail operations for both closed offices would move to Southgate.

Seventeen other post offices in southeastern Michigan, including 10 in Detroit, turn up on an August U.S. Postal Service closure list.

"Given the extraordinary decline in mail volume -- a decline of nearly 26 billion pieces this past year alone -- we must take action to reduce the size of our retail and delivery network," Charles Howe, U.S. Postal Service district manager said in a statement to CBS News.

The closings are part of a nationwide trend. The USPS is considering closing 3,700 offices and laying off more than 120,000 workers to overcome an $8 billion budget shortfall, according to the Baltimore Sun.

Some union members say the closings and layoffs are unnecessary. Instead, they blame a 2006 congressional mandate to fund pensions for the next 75 years for the postal service's current fiscal woes.

UPDATE 6:20 p.m. -- Also on Tuesday USPS announced that it would not close any facilities nationwide until May 15. The agency is waiting for Congress to come through with a budget overhaul. Depending on what happens, the downriver post offices could still be closed.
