Flood Resiliency and Land Stewardship Act This bill amends the purpose of the Regional Conservation Partnership Program (RCPP) of the Department of Agriculture (USDA) to include the prevention and mitigation of the effects of flooding and drought and the improvement or expansion of flood resiliency. (Under the RCPP, USDA enters into agreements with eligible partners to deliver conservation projects in specific geographical areas. Within an RCPP project, producers enter into contracts and agreements with USDA to carry out eligible conservation activities.)
