§ 66-187. Typical street cross section, underdrain.

In lieu of an enlarged right-of-way, or drainage easements along the proposed street right-of-way, an underdrain may be used to provide drainage for surface water and/or water from the subbase of the street. Included with the submittal of the preliminary plan shall be a profile and cross section of the underdrain system and arrangement of the filter media surrounding the pipe. Selection of drain size and arrangement of the surrounding filter media shall be designed by a licensed professional engineer, and his statement to this effect shall accompany the plan for approval. When underdrain is used, the base and subbase as much as possible shall extend to the right-of-way line. It should be understood that surface drainage will still have to be handled satisfactorily and separate from the underdrain.
