California’s infrastructure, from highways to levees to water systems, received an overall grade of “C-” from the American Society of Civil Engineers in its annual evaluation. The Golden State’s airports, wastewater systems and ports received the highest grade at “C+,” while energy came in at a near-failing “D-” in the report released last week. “Recent investments have been made across all 17 categories that comprise the state’s infrastructure network,” the ASCE noted. “However California is playing catch-up after years of under-investment and must identify investment needs for resilient infrastructure in preparation for future natural and man-made disasters.”
