There were broken portions of the headwall, and sections of the culvert that were missing (see Exhibit B). Additionally, the northern concrete headwall was being supported by 2 different trees.
This project replaced the culvert and headwalls during the month of February (while the lake was empty). The project also removed the two trees that were impacting the northern headwall.
