Ciorba Group has extensive experience designing drainage systems for new and rehabilitated roadways and bridges.  We regularly work on various types and scales of transportation drainage systems, including local municipalities and townships, counties, and state systems such as IDOT, INDOT, and the Illinois Tollway.  Depending on the roadway’s jurisdiction and the project’s funding sources, Ciorba utilizes the appropriate design criteria to meet all local, state, and federal requirements.  Project components include inlet spacing analysis, storm sewer design, cross-road culvert design, ditch design, and any associated detention or floodplain compensatory storage requirements.  Many projects include challenges related to available space for drainage improvements.  We systematically tackle these challenges with effective drainage designs that serve the need and fit within the land available
