California Water Fix and Eco Restore

California Water Fix and Eco Restore, formerly known as the Bay Delta Conservation Plan, is a controversial $15 billion[1] plan proposed by Governor Jerry Brown and the California Department of Water Resources to build two large, four-story tall tunnels to carry fresh water from the Sacramento River under the Sacramento-San Joaquin Delta toward the intake stations for the State Water Project and the Central Valley Project.[2]

Each tunnel would be 150 feet (46 m) below ground,40 feet (12 m) in diameter and 30 miles (48 km) in length. The tunnel project is as big or bigger than the English Channel Tunnel and Boston's Big Dig. The project would also include three new intakes with a capacity of 9000 cubic feet per second each, and a total annual yield of 4.9 million acre-feet.[3][4] The proposed cost for the tunnels is $15 billion, with $8 billion additional devoted to habitat restoration. The project is to be funded by revenue bonds created by the agencies who benefit, and paid by the farmers and urban water users who benefit from the project, not taxpayers, and does not require legislative or voter approval.[1][5]

Background

The precipitation in the northern part of California is vital to the arid southern portion of the state where water demand is met only by importing water from distant locations. In the 1960s, Governor Pat Brown successfully supported two large projects that reallocate water from the wet northern portion of the state to the more arid southern part. In the early 1980s, his son and then Governor Jerry Brown attempted a third, the Peripheral Canal, which failed to gain voter support. After his re-election as Governor in January, 2011 Jerry Brown once again proposed a project attempting to support this goal.

Central Valley Project and State Water Project

The Central Valley Project (CVP) is a federally owned and operated project completed in the 1970s. It has 600 miles (970 km) of canals and moves up to 13 million acre feet per year and generates electricity—about half of which is used by the system. Overall, depending on the weather and amount of rain, up to 80% of of water in the state is used for agriculture.[6] Before the Central Valley Project Improvement Act (CVPIA) in 1992, the water transported from northern California went primarily to agriculture (90%), with the remaining 10% going to urban users. The CVPIA required that 11% of the water go to environmental uses, with agriculture getting only 79% of the water and urban users still getting 10%.

The State Water Project is owned and operated by the state and was conceived and supported in the late 1960s by Governor Edmund Pat Brown. The SWP has 700 miles of canals and can move 5.8 million acre feet of water per year. It uses more than twice the amount of electricity it generates. The water transported by the State Water Project is divided 75% for urban use and 25% for agriculture.

Peripheral Canal

When Governor Jerry Brown was previously in office, he championed an earlier version of the tunnels project called the Peripheral Canal. It would have transported water from near Sacramento around the Sacramento-San Joaquin Delta into the Central Valley Project, and exported it to southern California. It was submitted to the voters for approval as a ballot referendum in 1982 but was turned down.[7]

Bay Delta Conservation Plan

The Water Fix and Eco Restore project was previously called the Bay Delta Conservation Plan. When proposed in 2009, the project as originally conceived included both plans for building the tunnels and restoring the delta. The Bay Delta Conservation Plan included restoring 100,000 acres (40,000 ha) over a 50-year span. The US Fish and Wildlife Service said it would not issue permits for the plan because the state could not prove that the habitat restoration project would help the salmon, sturgeon, or delta smelt.[8]

As a result, the Brown administration drastically reduced the habitat restoration plan and separated the water supply improvement plan,[8][9] renaming it the Water Fix and Eco Restore project. The revised plan proposes short-term permits for each endangered species encountered. The Eco Restore project only attempts to restore 30,000 acres (12,000 ha) over a five years at a cost of $300 million, funded with state bond money and other sources.[5][10]

Proposed Delta Tunnels

Responsible agencies

Six agencies are responsible for funding the project. The Santa Clara Valley Water District, receives 40% of its water from both the SWP and CVP, and serves 1.9 million residents of Silicon Valley. The San Joaquin River Exchange Contractors Water Authority serves 240,000 acres (97,000 ha) and received 50% of its water from CVP in 2015. The San Luis & Delta-Mendota Water Authority is a wholesale water provider that delivers CVP largely to farmers covering 2,100,000 acres (850,000 ha) million acres in 29 separate districts. It received no CVP water in 2014 and 2015. The Kern County Water Agency is a SWP contractor serving 674,000 acres (273,000 ha). It received 20% of its normal SWP allotment in 2015. The powerful Westlands Water District is the largest member of San Luis Authority. The Metropolitan Water District of Southern California is a SWP contractor and one of the largest players in California water politics, serving 19 million urban residents. It is one of the tunnels' strongest supports.[11]

Water Fix

The Water Fix project was proposed to address the issues of the water system infrastructure in California being "unreliable and outdated".[12] The proposal also prepares for possible threats to the water system such as climate change and seismic activity.[12]

Currently, water is exported from the Sacramento-San Joaquin Delta to the State Water Project and the Central Valley Project. The water flows through a maze of river channels and sloughs before entering the Clifton Court Forebay north of Tracy. From here, the Banks Pumping Plant pumps water into the California Aqueduct and the South Bay Aqueduct; the nearby Bill Jones Pumping Plant pumps water into the Delta-Mendota Canal. If not diverted, the water would flow into San Francisco Bay. The freshwater/saltwater gradient has moved inland because of the 5 to 7 million acre feet (6.2 to 8.6 km3) of water being removed from the delta each year for delivery to the Central Valley and Southern California.

The Water Fix proposal includes two categories of construction: the north tunnels and the main tunnels. The north tunnels are three separate tunnels, each about 14 miles long, which connect the three intake facilities to the Intermediate Forebay (IF).[1] The main tunnels are intended to connect the Intermediate Forebay to the Clifton Court Forebay. These twin tunnels, depicted in the adjacent image, will be about 30 miles long.[1] The main tunnels are also known as the twin tunnels, but are different from the Peripheral Canals proposed in 1982. The Water Fix is intended to make conveyance of water for the State Water Project and Central Valley Project more reliable while relieving environmental pressure on the Delta area.

The proposal details the planning and construction of the project. It provides that the Department of Water Resources enters a contract with the project manager for the Water Fix and a program director will coordinate with the department.[1] Managing the project would be a board of directors known as the "Authority Board", which would receive and review monthly status updates on the construction of the Water Fix.[1] The "Authority Board" has a "Program Advisory Group" to advise board members, made up of technical experts from the Department of Water Resources.[1] The director of the Department of Water Resources would have final control of all aspects of the project.[1] To control and monitor each of the facilities the proposal includes a Supervisory Control and Data Acquisition (SCADA) system at each location which can be controlled locally or remotely. The system would connect to the Delta Field Division Operations and Maintenance Center as well as to the Joint Operations Center in Sacramento.[1]

Though the Water Fix proposal aims to resolve some issues with the California water system, there are many it does not address. The plan does not consider the possibility that there could be less flow in the Sacramento River, not does it address how to allocate water to fisheries found in the Delta, some of which are already struggling because of current water exports from the Delta.[13] There are also no plans to deal with the extreme subsidence that is happening in the Delta.

Eco Restore

The Eco Restore plan is to mitigate the effects the California Water Fix will have on the environment either through construction or operation.[12] The planned Eco Restore includes upwards of 30,000 acres for restoration; 1000 of these acres will be for upland and habitat protection linked to flood protection, 3,500 acres for wetland restoration, 9000 acres for tidal and sub tidal zones, and the last 17,500 will be permitted for floodplain restoration.[14] Another item to note is that the Design and Construction Enterprise intends to get 2018b permits from the Department of Fish and Wildlife, this permit allows the incidental take of a species listed on the Endangered Species Act.[1]

Table of the endangered or threatened species that will be affected by the proposed California Fix

Proposition 1 allocated $7.545 billion in general obligation bonds for water projects including surface and groundwater storage, ecosystem and watershed protection and restoration, and drinking water protection.[1][15]

Restoration is viewed by ecologists as an important way to promote the recovery of an ecosystem.[16] The California Water Fix was subject to a biological assessment, which is required for any project that has the potential of having an impact on the environment. The table to the right shows a page from the biological assessment which lists threatened and endangered species that have the potential of being affected by the implementation of the California Water Fix.[1]

There are currently 12 environmental commitments that are included in the proposal for the Eco Restore. The Bay Delta Conservation Plan proposal before this included similar mitigation under the name of, "conservation measures" and there were 21 of these measures; the 21 have been cut down to 12 measures and are now known as environmental commitments for the Eco Restore.[17] The environmental commitments are as follows:[1]

Environmental Commitment Details
Environmental Commitment 3 Natural Communities Protection and Restoration
Environmental Commitment 4 Tidal Natural Communities Restoration
  • Restoring tidal natural communities and uplands (including transitional uplands & wetland restoration)
  • Includes restoration of 59 acres (this is subject to change, but total will not be more than 177 acres)

Environmental Commitment 11 Natural Communities Enhancement and Management
  • This actions states that there will be enhancement and management of all protected and restored areas
Environmental Commitment 12 Methylmercury Management
  • The goal is decrease the production of methylmercury in restored tidal wetlands
  • This no longer includes monitoring the Yolo Bypass.
Environmental Commitment 15 Localized Reduction of Predatory Fishes
Environmental Commitment 16 Nonphysical Fish Barrier
  • Installation at Georgiana Slough to alter the direction of juvenile salmon so they avoid channels with more risk

Financing

According to the Metropolitan Water District, southern California receives about 30 percent of its water supply from delta sources originating in snowmelt from the Sierra Nevada. In 2014, the state proposed that customers of the project would make billions of dollars in annual fixed payments, even during drought periods when water deliveries would drop or even cease. The state treasurer's office said the $25 billion financing plan would only be possible if water agencies adopted a set yearly payment plan. The State Treasurer's Office released a study in November, 2014 conducted by consultants who found the project was feasible. According to the plan, the cities, water agencies—including an estimated 25 million residents—and farmers of 3 million acres, not taxpayers, would be responsible for the billions of dollars in debt over 50 years, even during dry years while receiving little or no water.[18] The Metropolitan Water District has stated that the project will only cost each homeowner $5 a month, but it hasn't provided any analysis to support the figure. Critics say large projects like this tend to go over budget and the actual cost will be much higher.[18]

Legislative and voter approval not required

The state is planning to fund the project using bonds issued by the water agencies, not the state, which if successful would not require approval by the state legislature or a public vote.[18] The study said the annual payment plan is required to sell revenue bonds at reasonable rates.[19][20] But several of the agencies who would be required to pay for the construction project have stated they can’t justify the costs if there’s a chance they’ll end up with less water.[18] On November 8, 2016, California voters defeated Proposition 53, which would have required a public vote on any projects backed by state-issued revenue bonds over $2 billion, including the WaterFix project.[18]

Westlands fine

In March, 2016, the Securities and Exchange Commission assessed a rare fine on Westlands in a settlement for misleading bond investors about the impact that the drought and water cuts had on its revenues. Their action raised concern about their ability to finance the WaterFix project.[21]

Audit ordered

After Westlands was fined for its questionable spending and accounting practices, the Joint Legislative Audit Committee in August 2016 requested an audit of the project by the California State Auditor. The audit will be started in April 2017 and take about seven months to complete. [22]

Comparable projects

The size of the WaterFix project is as large or larger than English Channel Tunnel and Boston's Big Dig,[21] both of which were significantly more costly than originally anticipated. The Channel Tunnel project at £4.65 billion (about USD$5.10 billion) was 80% over its predicted budget.[23] The Boston highway project grew from an original estimate of $2.8 billion in 1982, and by December 2007 had risen to over $14.6 billion, a cost overrun of about 190% when adjusted for inflation.[24] This was before a series of significant defects that resulted in several deaths were discovered. The Boston Globe estimated that the project will ultimately cost $22 billion, including interest, and that it would not be paid off until 2038.[25]

Benefit-cost study

In August, 2016, a comprehensive benefit-cost analysis conducted by the University of the Pacific's Center for Business and Policy Research found that the project provided 23 cents in benefit for every dollar spent, or in the most optimistic scenario, 39 cents per dollar. Economist Jeffrey Michael, a professor of policy at the university, wrote that the project would deliver too little additional water for the cost. The study was funded by the Delta Counties Coalition, representing Contra Costa, Sacramento, San Joaquin, Solano, and Yolo county governments.[26]

Current legislation

The application of the Eco Restore is not guaranteed because of a bill that has been introduced in the House and has currently been assigned to the House Appropriations committee. Bill H.R. 5055 makes it so there is a no funding for restoration along the San Joaquin River and it would make it so that pumping is mandated out of the Sacramento-San Joaquin Delta.[27] If the bill is passed there will be no mitigation for the damage that may occur along the San Joaquin river or in the Delta due to the California Water Fix.

Another bill that may change the fate of the California Water Fix and Eco Restore is Assembly Bill 1713[28] If passed, it would require California voters to approve the Water Fix and Eco Restore.[29]

Environmental impact

The basis for the project is that a new diversion system and extensive habitat restoration would improve delta conditions, boost the populations of imperiled fish, and ease limits on exports.[5] Those who favor building the tunnels state that pumping water through the tunnels to the pumping plants would mitigate the problem of salt water intrusion into the delta, as the pumps would no longer pump directly from the delta. Proponents also believe that the project would protect the state's water system from the sea level rise expected to occur due to global warming.[30] It would also "reinstate a more natural direction of river flows in the South Delta by 46-160 percent".[4]

However, opponents note that some of the water that would normally flow into the delta is obligated under senior water rights to farmers in the delta.[30] Opponents are concerned that the project will reduce the amount of freshwater flowing through the delta and cause worsening saltwater intrusion. Farmers in the delta are among the most opposed to the project because it would decrease the amount of water available to them for irrigation.[31] The current federal and state delta water projects that fill the big aqueducts with water for southern California have altered natural water flow, causing the water in the estuary to run backward. They have disturbed the natural salinity patterns [32]

The flow of freshwater to the sea is about half of what it once was.[5] To attempt to improve the quality of the bay's fresh water supply, the California State Water Resources Control Board has begun revising the fresh water standards which have not been updated since 1996. In September, 2016, the board proposed rules that would allow up to 40 percent of the San Joaquin River watershed’s water to flow through into the delta during the winter and spring months. Current rules allow the pumps to suck as much as 90 percent of the water from the river into the canals for Southern California's use.[33]

Even though environmental regulations bar pumping under certain conditions, the pumping has pulled migrating fish away from their intended destinations. The formerly large populations of Delta smelt, Chinook salmon and other native fish have dropped to historically low levels. At least 35 native fish, plants and animal species have been added to federal and state endangered-species lists.[5][32] The Delta smelt may be near extinction. State biologists conducted a study of Delta smelt in 2015, and found only six in the study area, where prior surveys netted hundreds.[34][35]

The WaterFix plan does not provide any guarantee how much water the project would produce each year. When the Bay Conservation Development Plan was dropped, so was the 50 year plan. The current plan relies on a year-to-year environmental permits, which causes uncertainty about the plan's ability to fulfill its purpose.[32]

Several environmental groups are opposing the project, including California Water Impact Network, Restore the Delta, and Delta Tunnels Action.[34] Farmers in the delta are among the most opposed to the project because it would decrease the amount of water available to them for irrigation.[31]

Delta islands purchase

The Metropolitan Water District of Southern California passed a measure to buy four delta islands for $175 million earlier in 2016, this buying of delta islands was challenged by many organizations (including San Joaquin, North Coast Rivers Alliance, Pacific Coast Federation of Fishermen's Association), but a district court did decide that it was legal for the water district to purchase these islands because there are no negative impacts of their purchase as of yet.[36]
