II. State DOT Survey and Interviews

To identify and recommend solutions that provide significant habitat connectivity benefits, and are cost effective and immediately implementable using readily available technology, the following outreach was conducted with State DOTs across the country:

  • 8 Minimization Phone Interviews  (selected states based on NCHRP Report 615)
  • 1 Online Screener Survey  (to determine Avoidance & Compensation candidates)
  • 7 Avoidance & Compensation Phone Interviews  (based on results of Online Screener Survey)

The following section describes the results of this outreach.  The online screener survey was run while the minimization interviews were being conducted, and based on the results of the screener survey, interviews were conducted with 7 states that were found to have such avoidance & compensation techniques in place and were willing to discuss them further. The results of the two sets of interviews assisted in the development of the flow chart by identifying key steps and techniques to assess and mitigate the impacts of existing and planned highway development on aquatic and terrestrial habitat fragmentation, based in part on the actual experiences of State DOTs.
