Parisian municipal workers from every branch of the city's staff came to the aid of people, including the agents of Métro Line 8, who received a recommendation for special praise for their diligent work on the Left Bank. As the water began to rise, they fanned out across the area, preparing residents for what was to come.
In the words of the nomination: "They immediately warned the inhabitants and businessmen of the Grenelle neighborhood and recommended that they protect their merchandise and furniture for the time being." For days, these men returned to place after place, checking on people and making sure that everyone was safe. Several of them spent hours at a time in water at least two feet deep, collecting scraps of wood to construct rafts and walkways that could move stranded people out of harm's way.
