York County Commissioners on Wednesday voted to approve $10 million in financing for a $27 million project to switch the county's 911 radio communication frequencies.

Congress ordered the switch to a different bandwidth a few years ago, following a recommendation from a federal commission formed after the Sept. 11, 2001, terrorist attacks.

Under the project, the county must shift from its current T-band frequency to the 700 MHz frequency.

Reimbursement: The federal government has committed to pay back at least part of the cost for the counties that make the switch, but officials said they haven't been told when or how much.

The work must be completed by 2019, when the government will take back the bandwidths currently being used.

The project is expected to start in March and run 41 months, with completion and a new system launch expected in summer 2017.

Bond issuance: Wednesday's vote secured $10 million through a bond issuance at a rate of 2.6 percent, to be used for the project's early equipment purchases, said Doug Hoke, vice president commissioner.

He said the 2.6 percent rate, considered low in the lending industry, can be attributed to the county's stellar credit rating.
