A post office that has served Manoa Valley residents for decades will not be shuttered at the end of this month, as was expected.

U.S. Rep. Ed Case announced in a press release Wednesday that the Manoa Post Office Contract Postal Unit will instead remain open.

P.O. box customers were informed beginning in late August that the facility would close Sept. 30.

According to Case’s office, there was no explanation for the abrupt closure, nor any explanation of how the United States Postal Service would continue to service Manoa, a large neighborhood which is located on Oahu.

In a Sept. 17 letter Case complained to Postmaster General Louis DeJoy, pointing out that many federal cost-benefits analysis formulas “are not viable for Hawaii.”

Hawaii has “very high land prices and cost of goods and services,” Case explained.

The congressman, a Democrat, said the USPS has since reached an agreement with the operator of the Manoa Contract Postal Unit that will allow it to continue operations at the Manoa Marketplace.

“This is certainly good news, not just for the 24,000 residents in the community I was privileged to represent for so many years in our State House, but for delivery of government services where people live and work wherever possible,” said Case in his press release. “I applaud our local, regional and national USPS for taking a second look, recognizing local realities and making it work.”
