City-parish and state officials are expected to speak about the 2016 flood and ways to mitigate the effects of future floods during Together Baton Rouge's Flood Matters Assembly scheduled 6:30 p.m. Tuesday.  

Together Baton Rouge, a coalition of residents and houses of worship, wants to build grassroots momentum to improve flood prevention, encourage development in higher, less flood-prone areas, and push for an overhaul of the city-parish drainage system, organizers said in a statement.

"This event will bring together key elected and appointed officials with citizens affected by the flood and others interested in taking action," the group said in the statement, "as we seek to help galvanize the political will we need to address flood recovery and flood prevention as aggressively as our circumstances demand."

Officials who, the group says, have confirmed their attendance for the event at First United Methodist Church, 930 North Blvd., are Pat Forbes, director of the state Office of Community Development; Frank Duke, director of the city-parish Planning Commission; Rowdy Gaudet, assistant chief administrative officer for city-parish Public Works; Dietmar Rietschier, director of Amite River Basin Commission; Metro Council members Trae Welch, Erika Green and Tara Wicker; and state Rep. Valarie Hodges, R-Denham Springs.

In addition to raising awareness of the region's flooding problems, the group plans to launch a campaign at the assembly to promote interest in the Restore Louisiana Homeowner Assistance Survey.

The survey is a first step that those affected by the 2016 flood must take if they want to access nearly $1.7 billion in federal recovery assistance.
