It will be the occupants' responsibility to maintain a structurally sound mail box within any Lenawee County Right-of-Way. The Road Commission will repair or replace mail boxes which are physically hit by Road Commission equipment with a standard mail box and post. Mail boxes that are not capable of withstanding the force of flying snow resulting from snow removal operations will be the occupant's responsibility. It will be the occupant's responsibility to clear the snow in and around his own mail box.
