The grades by sector are: dams (D), drinking water (D), hazardous waste (D), levees (D-), solid waste (B-), wastewater (D), aviation (D), bridges (C+), inland waterways (DO, ports (C), rail (C+), roads (D), transit (D), public parks and recreation (C-), schools (D), and energy (D+).

To contrast, the 2010 Report Card for Oregon's Infrastructure sector grades included aviation (D), bridges and roads (C-), dams and levees (C), drinking water and wastewater (D), energy (C), navigable waterways (B-), rail (C), solid waste (B), and transit (C-).
