From 1904 to 1925, he was founding mayor of Beausoleil, a town adjacent to Monte Carlo, which had previously formed part of La Turbie and had been known as Monte-Carlo-Supérieur.
While married to Elisabeth Lanxade, his name was also linked to Madame Chinon, whose excessive gambling habits, indulged by Blanc, were widely believed by some observers to be substantially at the origins of the accusations of mismanagement which eventually led to Prince Louis' intervention and termination of his position at Monte Carlo Casino.
In the closing years of Blanc's life, up to his death in 1927, he suffered severely from paralysis, said to have been derived mainly from the reported stresses of his experience of dealing with the Monaco authorities.
The separate existence and prosperity of the neighbouring French town of Beausoleil may be Blanc's principal lasting legacy.
The town hall of Beausoleil in the rue de la République has a sculpture and gardens dedicated to the memory of Camille Blanc.
