AC § 27-689
(a)Required by soil bearing capacity. The provisions of paragraph one of subdivision (b) of section 27-700 of article eight of this subchapter shall apply.
(b)Required for lateral restraint. The provisions of section 27-694 of this article shall apply.
(c)Piles located near a lot line. Piles located near a lot line shall be designed on the assumption that the adjacent lot will be excavated to a depth of ten feet below the nearest legally established curb level. Where such excavation would reduce the embedded length of the pile, the portion of the pile exposed shall be considered as providing no lateral or vertical support, and the load-carrying determination in accordance with the provisions of article eight of this subchapter shall be made after the resistance offered by the soil that is subject to potential excavation has been discounted.
