State agencies in charge of modifying Warren County’s flood risk maps will educate local officials for 90 minutes before maps are shown to the public Nov. 9, a joint memo this week said.

Public viewing of new maps will be from 4:30 p.m. to 6:30 p.m. in the Board of Supervisors meeting room on the third floor of the Warren County Courthouse. At 3 p.m., one county supervisor, the mayor, an alderman and any appropriate engineers, administrators, planners or geotechnical staff have been asked to attend a briefing to inform them of the method by which the state updated parts of the existing maps, said Al Goodman, of the Mississippi Emergency Management Agency, also the state coordinator of the National Flood Insurance Program.

Updates involve 17 of the 45 sections of land that compose the county’s map that are in the most flood-prone zones, officials have said. The effort in Mississippi, undertaken by MEMA, FEMA and the Mississippi Department of Environmental Quality, is part of ongoing digitization of flood maps nationwide.
