This bill amends the Omnibus Public Land Management Act of 2009 to address aging water canals that run through urban areas and pose safety risks if they fail. It creates a new legal category called an "urban canal of concern," defined as a canal segment whose failure could endanger more than 100 people and that the Secretary of the Interior classifies as an urban canal reach. The bill authorizes the Secretary of the Interior or the local entity operating the canal to carry out extraordinary repair and maintenance work on these urban canals of concern. Under a cost-sharing arrangement, the federal government would cover 25 percent of the total repair costs without requiring repayment, while the remaining 75 percent would be advanced by the Secretary but repaid over time by the local operating entity, except in emergency situations. This legislation primarily affects local water districts and municipalities that manage canal systems originally built by the federal government but later transferred to local control, particularly in growing urban areas where aging infrastructure now runs through populated neighborhoods.
