Abstract:The Arizona Department of Transportation (ADOT) is committed to developing habitat, mitigation,
monitoring, and maintenance plans that replace the loss of the functions and values of an area and
are self-sustaining, thereby providing long-term compensation for habitat adversely affected by ADOT
construction activities. This study focuses on identifying administrative and biological criteria that are
important to the success or failure of mitigation and/or restoration projects and developing
recommendations from these criteria. Files on ADOT and non-ADOT riparian habitat restoration and
mitigation projects were obtained from several sources and were reviewed for project applicability to
the study goals. Thirty-four sites were selected for further analysis. In addition, employees from the
Corps and ADOT were interviewed to gain a realistic perspective. A review of project files, associated
site data sheets, and analysis of the interview results yielded mitigation practices and a variety of
administrative and biological problems commonly associated with restoration projects in Arizona.
More specifically, the problems are associated with ADOT mitigation projects for which Clean Water
Act Section 404 permits are involved. Recommendations based on analysis of these problems, review
of applicable peer-reviewed literature, and research team expertise, are offered in this report to aid
future ADOT projects and all future restoration projects in Arizona, regardless of the agency or
organization undertaking the restoration of riparian areas.
