Department of Transportation. Federal Highway Administration AB - The main objective was to assemble a framework for writing effective visual impact mitigation measures for adverse visual resource impacts and preparing design guidelines. This included strategies to implement National Environmental Policy Act (NEPA) visual impact mitigation commitments through transportation project planning, design, construction, and maintenance. FHWA Region 8 recommended adapting FHWA “SMART” (Specific, Measurable, Attainable, Realistic and Tangible) concepts as a tool to inform the development of more effective visual impact mitigation measures and design guidelines. Implementation: Once a framework was developed to evaluate the existing visual mitigation writing process using SMART criteria, the team contacted and invited landscape architects representing four state DOTs and the US Forest Service to contribute to this research by providing examples of VIA reports (case studies) and participating in interviews with CDOT. To facilitate the composition of mitigation strategies, the team recommended using guidance tools, including work flowcharts and a Mitigation Planning Checklist, to organize, develop, and write effective mitigation measures.

Additionally, climate change is projected to increase the frequency of extreme precipitation events, leading to an increase in embankment failure potential. This study evaluated (1) the effect of future climate scenarios on the long-term performance of clay embankments, and (2) the effect of extreme precipitation events brought about by future climate scenarios on the hydromechanical response of clay embankments to these extreme events. The study area examined was Central Los Angeles, CA. A multi-phase hydromechanical geotechnical model was developed for exemplary high plasticity and low plasticity clay embankments with varied side slope angles. Overall, it was concluded that climate change is generally projected to adversely affect the performance of clay embankments both in the long-term and during extreme events.
