When permits are requested to disturb, dig up or in any way obstruct any street or public place in the city, the Building Official may require from the applicant, before granting a permit, a cash bond, conditioned to secure the city against all loss, damage or injury of any kind which may result to the city by reason of the disturbance, digging up or obstruction of the street. The amount of the bond shall be as determined by the Director of Public Works and the City Engineer.
