GRAND RAPIDS (WZZM) -- A Kent County spokesperson says 150 people, forced from their homes by flooding, are back home.

The high waters forced 700 people to evacuate over the past week. That number does not include Grand Rapids, where 1,000 people are displaced after an estimated 1.3 million gallons of water knocked out power at the Plaza Towers downtown.

A no-contact advisory for the Grand River remains in effect because of dangerous debris and contamination. County workers plan to collect and test water samples, starting Thursday.

Meanwhile, the Kent County Board of Commissioners is expected to decide whether to extend the local state of emergency for another 30 days during their Thursday meeting.
