![]() Sacramento County’s response to the Validation Complaint explains how the General Bond Resolution goes far beyond the authorizing statute: The Delta Program General Bond Resolution authorizes bonds to be issued for “phases” of the “Delta Program.” Governor Gavin Newsom’s two-intake, one tunnel project could be just the first “phase” of the “Delta Program.” Later phases could include a second tunnel and the other three intakes for DWR’s original five-intake, twin tunnel project. ![]() Delta Program facilities may include, but are not limited to, water diversion intake structures located on the Sacramento River and a tunnel to convey water to Banks Pumping Plant. ![]() It is a sweeping assertion of unlimited authority to issue bonds for an open-ended “Delta Program.” The General Bond Resolution statesĭelta Program means the environmental review, planning, engineering, design, and, if and when the Department determines to be appropriate, acquisition, construction, operation and maintenance of facilities for the conveyance of water in, about and through the Sacramento-San Joaquin Delta, subject to such further specification thereof as the Department in its discretion may adopt. In reality DWR’s Delta Program General Bond Resolution goes far beyond a resolution for a single project. The State Water Contractors have countered that DWR is simply “validating its own authority to issue revenue bonds to raise funds.” The General Bond Resolution is expected to fund Governor Newsom’s Delta tunnel project, which is currently estimated to cost $15.9 billion.
