A. Subgrades subject to poor drainage, underground seepage or a high water table shall be adequately drained for roadbed stabilization. Drains shall be installed to prevent the high ground water level from coming within four (4) vertical feet of the bottom of the roadway pavement. Perforated pipe shall be used to carry away collected water. French drains that contain no pipe are unacceptable. (Ord. 2007-06, 8-14-2007)
