Concessions are granted in return for payment of a capital sum, the amount of which is set by the municipal council.
Temporary concessions, thirty-year concessions and fifty-year concessions are renewable at the price of the tariff in force at the time of renewal.
Failing payment of this new fee, the conceded plot reverts to the municipality. However, it may not be taken back by the commune until two years after the expiry of the period for which the plot was granted.
In the interval between these two years, the concession holders or their successors in title may make use of their right to renew. Communes are required to inform concession holders and their successors by any means of the existence of this right of renewal.
