§ 190-19. Protection of adjoining property.

Whether or not a permit is required under this chapter, any person causing any excavation to be made shall provide such sheet piling and bracing as may be necessary to prevent the earth of adjoining property from caving in before permanent supports have been provided for the sides of such excavation; and whenever provisions are lacking for the permanent support of the side of an excavation, the person causing or having caused such excavation to be made shall build a retaining wall at his own expense on his own land, such retaining wall to be carried to a height sufficient to retain the adjoining earth and to be in accordance with specifications acceptable to the Building Inspector.
