Flood debris that's been festering along state highways since historic levels of water in August wrecked nearly a third of structures in East Baton Rouge Parish should finally be picked up over the next several weeks.

The city-parish announced late Tuesday that it reached an agreement with the state's Department of Transportation and Development and FEMA to coordinate pickup of debris in right-of-ways on state highways. The city-parish's debris removal crews will sweep up the flood remains on state highways in East Baton Rouge, Baker, Zachary and Central.

Debris pickup costs have already added up to more than $30 million, with FEMA expected to reimburse close to $32 million and the city-parish being left on the hook for roughly $3 million. Contractors have picked up 1.92 million cubic yards of debris.

City-parish leaders are asking those who live along state highways to move their debris curbside for pickup. More than 40 roads will be covered in the effort, including the following:

As with debris removal that's been ongoing in the parish, city-parish leaders say they cannot pick up construction and reconstruction debris as people rebuild. They have not reached an agreement for FEMA to reimburse those costs, and say contractors are responsible for hauling off that type of debris themselves.

“Our decision to pick up eligible flood debris along state routes is intended to address many of these remaining needs and provide relief to residents throughout East Baton Rouge Parish who live on state highways, helping them  like so many of us impacted by this flooding – continue on the path to full recovery," said Mayor-President Sharon Weston Broome in a statement.
