All dust resulting from wrecking or demolition operations shall be immediately settled by wetting the same with water of sufficient quantity to prevent the dust from leaving the site of the demolition or wrecking project. Demolition shall be stopped during periods of high winds that carry the dust from the site before it can be settled by wetting. The permittee shall be responsible for maintaining clean public streets during such operation. The permittee must obtain the necessary permits for water from the manager of the division of water and sewers and pay for such permits and for water used.
The permittee shall wash off public property to remove all silt and dust. In order to prevent such material from entering any public sewer, the permittee shall properly pond the gutter in order to permit such material to settle, and it shall be then cleaned up and hauled away. This procedure shall be followed in accordance with the requirements and policies of the water and sewers division. This section shall also apply to Section 15.40.050 of this title.
