SOUTH PORTLAND — The impact of Superstorm Sandy and the lessons Maine can learn from the storm will be a focus of 2013 Maine Beaches Conference.

Friday’s event at Southern Maine Community College in South Portland is expected to draw as many as 200 coastal property owners, recreational beach users, volunteer beach monitors, scientists, public officials and others.

The daylong symposium features sessions on tourism, erosion control, pollution and other beach-related topics, with the opening session focusing on Sandy.

Sandy’s biggest problem was the storm surge with waters flooding 90,000 structures and damaging some 25,000 vehicles beyond repair.
