Question 20: This synthesis will also include case examples discussing current state DOT practices for using sustainable materials in ESC practices. During the development of the case examples, additional follow-up questions may be required to develop a better understanding of current approaches for incorporating sustainable materials into erosion and sediment practices. Would you be willing to participate in a follow-up interview? Note, interviews will take no longer than one hour to complete and will be in virtual video format.
