Volunteers from the veterans nonprofit organization Team Rubicon meet this morning with Butler First United Methodist Church representatives to prepare for flood cleanup.

Military veterans are helping out victims of the flooding in Butler last week.

Team Rubicon, an international nonprofit organization that uses volunteers who are mainly veterans, began its efforts this morning.

Jonah Thompson, Pennsylvania field operations coordinator for Team Rubicon, said volunteers, which also include people who are first responders, will aid residents whose basements were flooded.

“The key is to get all the water out,” he said.

Along with water and mud, crews will tackle mold.

Thompson said mold can make a residence uninhabitable if left to fester in walls and insulation.

“That's a significant health hazard,” he said.

Thompson said volunteers will pry off flooring if necessary.

Workers met at First United Methodist Church on East North Street.

Thompson said Team Rubicon has roughly 50 employees and 45,000 volunteers.

The organization was founded after two U.S. Marines organized a trip to Haiti in 2010 after a major earthquake hit Port-au-Prince.

Among the tasks Team Rubicon does are debris management, damage assessment, disaster mapping and hazard mitigation.

On international operations, Team Rubicon provides emergency medicine.

In addition to emergency response, volunteers also participate in fitness and social events, and service projects.

The organization's headquarters is in Los Angeles.

Wednesday night through early Thursday morning, several streets were flooded after Sullivan Run overflowed.
