Yesterday, San Diego County Water Authority’s General Manager, Maureen Stapleton, sent a letter to CA Natural Resources Secretary John Laird asserting that Dr. David Sunding’s economic analysis for the Delta Tunnels project “may significantly overstate Southern California’s future demand for water from the Bay-Delta.” Ms. Stapleton’s letter explains that Dr. Sunding’s economic analysis used water planning assumptions from Metropolitan Water District’s 2015 Integrated Resources Plan (IRP) regarding the need for San Francisco Bay-Delta water. However, as Ms. Stapleton points out, MWD’s 2015 IRP only included local projects that were recently completed or under construction.
