To help improve the effectiveness of its sustainability policy, the Authority should revise the policy by May 2019 to more clearly differentiate between the construction and operation phases of the high-speed rail system. Further, it should ensure that each objective in each section of the policy is associated with quantifiable metrics for evaluating implementation.
To allow it to evaluate the sustainability of the high-speed rail system's construction, the Authority should, by May 2019, perform and document a review of its compliance with its existing quality controls related to ensuring the validity and completeness of contractor-reported data. The Authority should also establish a formal process to perform such reviews periodically.
To help ensure that it meets its sustainability goals, the Authority should comprehensively compare the three construction projects' performances to their construction contractors' original baseline estimates on a quarterly basis. It should perform the first of these comparisons no later than May 2019.
To help ensure that its contractors' proposed environmental impacts are reasonable and to measure the progress of its sustainable construction efforts over time, the Authority should, by November 2019, identify and track standardized measures-such as project miles-that will allow it to compare construction impacts across the high-speed rail system's different construction projects.
To increase the transparency of its reporting, the Authority should, by May 2019, expand its quarterly small business, DVBE, and DBE utilization reporting to account for the total value of all its contracts and to identify the reasons it has exempted specific contracts.
