Designation of Initial Voting Members of Regional Flood Planning Groups (RFPGs)
In May 2020, the Texas Water Development Board’s Executive Administrator opened a solicitation for nominations of individuals to serve as initial regional flood planning group members to fill the 12 required voting interest categories for each of the 15 flood planning regions. More than 600 nominations were received during the nomination period.
At the October 1, 2020 Board meeting, the Texas Water Development Board (TWDB) designated the initial voting members of the 15 regional flood planning groups. These planning groups will be responsible for developing Texas’ first regional flood plans by January 2023, which will culminate in the state’s first-ever state flood plan.
For information on the selection process, please see the October 1, 2020, Board item.
The TWDB Regional Flood Planning Group Meetings webpage includes meeting agendas, meeting materials, and information to access and attend scheduled RFPG meetings. All flood planning group meetings and members are subject to the Open Meetings Act and Public Information Act. Meetings will include an opportunity for public comment and will be conducted in an open and transparent manner.
