Washington State Department of Transportation maintenance crews performed more than 2.6 million hours of work in 2015 without getting a single environmental notice. That’s roughly the equivalent of a two-man crew working every hour of every day since Alaska was purchased in 1867 and never once impacting the environment.

WSDOT recently published its quarterly performance and accountability report, the Gray Notebook (pdf 3.7mb). In addition to environmental compliance, the report takes a closer look at the data and the stories behind pavement conditions and whether they are improving, how commute trip reduction is reducing costs for drivers, and how drought conditions impacted Grain Train carloads in eastern Washington.

Highlights from these Gray Notebook articles include:

• WSDOT’s preservation backlog for pavement past due for rehabilitation declined by 10 percent between 2013 and 2014 due to strategic preservation activities (page 11)

• Employees at worksites with Commute Trip Reduction programs are leaving approximately 14,500 cars at home every day (page 22)

• Washington Grain Train carloads decreased from 1,974 in 2014 to 1,815 in 2015, a decline of 8.1 percent (page 34)
