Specifically, the Bay-Delta supplies some or all of the water needs for two-thirds of the state's homes and businesses and over four million acres of agricultural land. Water moves through the Bay-Delta's conveyance system of canals and channels, and is trans ported to cities and farms in the Bay Area, the San Joaquin Valley, and most of Southern California by the State Water Project and the federal Central Valley Project (CVP). This diversion of water for uses elsewhere in the state (particularly during drought years), together with other factors (such as water pollution), has resulted in the deterioration of the ecological health of the region and reduced the region's role as a fish and wildlife habitat. As a result, fish and wildlife populations have declined to the point where some species have been classified as threatened or endangered.
To address the declining fish and wildlife habitat in the Bay-Delta, the State Water Resources Control Board will implement over the next few years more stringent water quality standards for the Bay-Delta in com pliance with state and federal clean water laws. As a consequence, the ability of some of the 7,000 or so water right holders to draw water could be affected and it is almost cer tain that the supply of water to nonenvironmental users will be reduced.
The Bay-Delta also serves as an important agricultural region. Its productivity de pends on flood-protecting levees and freshwater releases to counter the intrusion of salty seawater. Diversion of water for other uses reduces the volume of fresh water to control salinity. At the same time, levees are deteriorating and must be maintained for the Bay-Delta to continue functioning as a viable agricultural region.
Problems Are Interrelated and Involve Competing Interests. The Bay-Delta problems of inadequate water quality, declining fish and wildlife popula tions, deteriorating levees, and uncertain water supplies to meet future needs are all interrelated. Unless these problems are addressed in a coordinated way, the Bay-Delta will not be able to provide in the future a reliable source of clean water for all users. Potential solutions that address one problem may have an adverse impact on supply available for other water users. Thus, balancing the needs of competing users of Bay-Delta waters must be a fundamental component of the overall solution to the state's water supply problem.
The basic objectives of the Bay-Delta Program are four-fold:
Status and Future of CALFED Bay-Delta Program. In mid-1996, CALFED staff and stakeholder advisors narrowed a list of potential Bay-Delta solutions to three broad conceptual alternatives. All three alternatives have common elements relating to water quality, levee stability, water use efficiency, and ecosystem restoration. (Ecosystem restoration involves restor ing the qualities of the natural environment that allow native fish, wildlife, and plants to prosper.) The alternatives vary primarily in the manner and scope of changes to the conveyance system and storage facilities. For example, one alternative essentially main tains the existing system of channels and canals which move water through the Bay-Delta, while the other alternatives make significant improvements, with one in cluding the construction of a bypass to carry water around the Delta.
The CALFED staff anticipates that environmental review of the three alternatives will be conducted through 1998, cumulating in final federal and state environmental impact reports and the recommendation for a single solution. Beginning in 1999, the chosen solution will be implemented, following detailed project-level environmental review. Full implementation will continue potentially for 20 to 40 years, depending on the solution adopted. As the implementation of individual projects will occur over time, funding needs will be spread out over many years as well.
CALFED Program Costs Substantial. The capital outlay costs for the three alternatives under consideration are estimated to range from $4 billion to $8 billion, with the ecosystem restoration component, common to all three alternatives, costing an estimated $1.6 billion. No matter which alternative is chosen, major capital expenditures would likely include the construction of water stor age facilities, the rebuilding of many miles of levees, and the development of hundreds of acres of new habitat. Funding for these capital costs will be sought from a variety of federal, state, local, and private sources. Some of these costs, however, will be met with existing program funding, such as that under the federal Central Valley Project Im provement Act.
The Legislature, recognizing the importance of the water supply problem and re lated Bay-Delta issues, has placed a bond measure on the November 1996 ballot. If ap proved by the voters, Proposition 204, the Safe, Clean, Reliable Water Supply Act (SB 900, Costa) would authorize the state to sell $995 million in general obligation bonds for various water quality and supply projects. Of this amount, $390 million would be available exclusively for ecosystem restoration projects to be identified in CALFED's final environmental review documents. Another $193 million would be used for other Bay-Delta improvements, including fish and wildlife restoration projects associated with the CVP, and levee rehabilitation. The remaining $412 million is dedicated mainly for loans and grants for local wastewater treatment, water recycling, water con servation, and water supply projects. Some of this funding could be used for projects related to the Bay-Delta.
The Bay-Delta Program and the CALFED process to develop a long-term solution to the Bay-Delta problem will continue regardless of the outcome of Proposi tion 204. As a chosen alternative is being determined, the Legislature will have to deliberate the policy merits as well as fiscal feasibility of the alternatives.Contact -- Mark Newton -- (916) 445-5921
In other positive developments, taxable sales were up by 7.8 percent between the second quarter of 1995 and the second quarter of 1996, the strongest increase since 1990. Exports of California goods also continued to expand in the first half of 1996, in creasing by 13 percent from the prior year.
September is a major month for tax collections, as it includes quarterly estimated payments from both individuals and corporations as well as a variety of other key pay ments. Collections for this period should provide the first significant indication of how the underlying trend in revenues during 199697 compares to that assumed in the 1996 Budget Act.
