Creeping floodwaters have consumed more than a quarter of the north parking lot at Warren Township High School.

This comes just a few days after volunteers and village employees spent another full day filling sandbags.

Mayor Kristina Kovarik called the flooding “epic,” and says those who volunteer are welcome.
