Goal: Integrate consideration of resilience in transportation decision
making• In support of 23 U.S.C. § 503(b)(3)(B)(viii), which directs the U.S. Department of
Transportation “to carry out research and development activities … to study
vulnerabilities of the transportation system to … extreme events and methods to reduce
those vulnerabilities.”

Resilience Related Regulations
• Risk-based asset management plans must address risks associated with current and future environmental conditions (23 CFR 515)
• Assets requiring repeated repair require analysis of alternatives (23 CFR 667)
• State and metro transportation planning should now include resilience as a planning factor (23 USC 134, 23 CFR 450)
• Metropolitan transportation plans shall include an assessment of capital investment and other strategies to… reduce the vulnerability of the existing transportation infrastructure to natural disasters (23 CFR 450.324(f)(7))

Corridors
• 44 States
• Covers over 100,00 miles of the NHS
• Preparing for Round 3 nomination
process. Announcement likely this fall,
and nominations due in early 2019
• Working with States / stakeholders in

Oregon DOT –Large Scale Solar in ROW
11
Demo Project, I-5 & I-205
• ODOT partnered with
utility and private firm to
build first large scale
solar ROW project in US
in 2008.
• Traffic safety clear zones
carefully considered in
the project setbacks.
Traffic control for
construction access was
reviewed by ODOT and
FHWA.
• Followed 23 CFR 645
Accommodation of
Utilities
• 594 solar panels (104kw)
provide about 1/3 of
energy needed to light
interchange
• Oregon’s transportation system uses ~ 50M kwh per yr, costing > $4M.
• ODOT has >19,000 lane miles of ROW. Solar arrays on < 1% of that could supply all
50M kwh ODOT uses annually.

Analyzing Transportation GHG Emissions
12
• Transportation is now the largest source of U.S. CO2 emissions.
• Analyzing GHG emissions analysis is challenging from a technical perspective
• Tools Developed and Ongoing Projects
• EERPAT (The Energy and Emissions Reduction Policy Analysis Tool) was designed by FHWA to provide an integrated framework for evaluating GHG emissions and mitigation strategies.
• NCHRP 25-56 will provide guidance on currently available, practical, and innovative methods for SDOTs to assess / advance mitigation strategies (Expected 2020 or 2021)
• ICE (the Infrastructure Carbon Estimator) is a FHWA spreadsheet model to estimate energy / GHGs from transportation facilities. MNDOT is leading a pooled fund effort to improve the model (Expected late 2019 or early 2020).
