Document Description
The Project is limited to one encroachment for improvements to an existing stream crossing that was replaced in 2020 under Lake or Streambed Alteration Agreement, Notification No. 1600-2019-0264-R1. Work for the stream crossing will include replacement and compaction of washed-out road fill along the length of an existing 30-inch diameter culvert using Class II road base rock, addition of a flared end-piece at the inlet set below grade to prevent water from flowing underneath the culvert, and addition of 6-9-inch riprap at the culvert inlet and outlet to minimize erosion.
