If, in the opinion of the Director of Public Works, any special or general deposit or undertaking is not sufficient for the proper protection of the public interest in the highways in which it is proposed to excavate or on which it is proposed to place obstructions, the Director of Public Works may require an additional deposit or may require that the amount of the undertaking be increased to such an amount as he determines will be sufficient to protect such public interest.
