MTG. 4114198 DIEGO COUNTY WATER AUTHORITY WATER
TRANSFER AGREEMENT CITY ATTY. lGE2
DEPT. CMWD
RECOMMENDED ACTION:
Adopt Resolution No. 10 13 supporting the Imperial Irrigation District/San Diego County
Water Authority transfezemeit, conditioned on an acceptable wheeling rate negotiated with
or imposed upon the Metropolitan Water District of Southern California.
ITEM EXPLANATION:
The San Diego County Water Authority Board of Directors released for public review and
comments of a water conservation and transfer agreement negotiated by the Authority with the
Imperial Irrigation District (IID).
Under the negotiated terms, IID would sell conserved Colorado River water to the Authority -
20,000 acre-feet in the first year of the contract and up to 200,000 acre-feet in the tenth year.
The contract would last 45 years, with a renewal provision for another 30 years. The water’s
cost would be determined by a formula that takes into account the cost of MWD water, the
estimate cost of wheeling the water to San Diego County, and the actual wheeling cost (which is
being negotiated with MWD). The negotiated contract builds on the extensive public input
compiled during review of the summary of draft terms in 1996. The water that would be gained
through the agreement would help the Authority achieve goals outlined in the Water Resource
Plan. It also would help the Metropolitan Water District maintain access to surplus water from
the Colorado River and would further development of California’s plan to live within its Colorado
River entitlement. (This proposed transfer is explained in additional detail in the attached
Exhibit A.)
CMWD staff will be making a presentation for further discussion of this important issue and to
provide this Board’s representative on the CWA Board direction by supporting this proposed
transfer by adoption of the attached resolution.
FISCAL IMPACT:
The cost of the transferred water to CWA will be equal to MWD rates and charges, minus the
wheeling rate and a declining discount starting at 25 percent.
However, as defined in the agreement, premium charges during times of shortages can be
instituted.
Additionally, prices can be redetermined when a water market is mature’ enough to establish a
new price, but no sooner than 10 years.
The cost of the transferred water to Carlsbad is expected to be equal to the cost of water from
MWD. This is contingent, however, on the final negotiated or legislatively imposed wheeling
rate from Metropolitan.

EXHIBIT A
DETAIL OF IID TRANSFER AGREEMENT
Background
The Water Resources Plan adopted by the Board in February 1997
projects that water demand in the Authority’s service area will increase by
approximately 30 percent between now and 2015, from approximately 600,000
acre-feet to 780,000 acre-feet. The plan outlines actions the Authority may take in
concert with its member agencies to ensure that San Diego County’s water
supply remains safe, reliable, and sufficient over the next 18 years. In brief, these
actions call for the Authority to supplement water purchases from the
Metropolitan Water District (MWD) with intensified development of local water
resources and the arrangement of long-term water transfers. The plan identifies
transfers as “one of the Authority’s greatest potential resources.”
In fact, the Authority has examined possible water transfers along with
other potentially feasible new water supplies over the years. One transfer
opportunity arose in 1995, when the IID Board of Directors adopted a policy to
consider water conservation and transfer programs with other agencies. IID
already had one conservation and transfer program in place. Under this program,
MWD pays for conservation projects in the Imperial Valley and receives the water
that is saved. The program will yield a maximum of 106,000 acre-feet of water per
year.
In September 1995, the Authority signed a memorandum of understanding
with IID concerning a long-term conservation and transfer program between the
two agencies. Since then, the Authority and IID have negotiated an agreement
through which the Authority would buy from IID water conserved through
extraordinary means, either by the district, its agricultural customers or both.
Negotiators for the two agencies agreed to draft terms for an agreement last year.
The Boards for the two agencies agreed in July 1996 to release a summary of the
draft terms for public review and comment.
Summary of draft terms
Under the draft terms, the Authority would buy conserved water - a
minimum of 200,000 acre-feet and a maximum of 500,000 acre-feet per year -at a
price that included the cost of on-farm conservation plus an incentive for Imperial
Valley farmers who volunteered for the program. The program would begin in
1999 with the transfer of 20,000 acre-feet of water; the quantity would increase in
20,000-acre-foot increments annually until it reached 200,000 acre-feet per year
in 2008. Further increases in quantity would depend on demand in San Diego
County and the ability to supply more through conservation in the Imperial Valley.
The contract would last for a minimum of 75 years and include provisions to
extend it for a total of 125 years.
Following public release of the summary of draft terms in July 1996, the
Authority acted to ensure that all interested stakeholders were informed about the
terms and had an opportunity to comment on them. Directors and staff conducted
more than 100 briefings on the draft terms. Every member agency and city in the
service area was briefed, as were many other interested organizations. The
Authority assembled a citizen committee comprised of representatives of every
member agency that reviewed the draft terms in depth and commented on them.
In addition, the Board held a formal public hearing.
Staff summarized all of the public input received by the Authority for review
by the Board. With this input, the Board refined parameters for staff to use in
further negotiations with IID. Negotiations resumed in June 1997 and led to a
proposed water conservation and transfer agreement between the Authority and
IID.
Water conservation and transfer agreement with IID
Under the negotiated contract, IID would sell Colorado River water
resulting from extraordinary conservation by its agricultural customers to the
Authority for 45 years. Either agency would be able to extend the contract for
another 30 years beyond the initial term. Deliveries in year one of the contract
would total 20,000 acre-feet and increase in 20,000 acre-foot increments annually
until they reach a maximum of 200,000 acre-feet per year in the tenth year. The
two agencies may agree to transfer an additional 100,000 acre-feet per year after
year 10. The water would result from voluntary extraordinary conservation by
Imperial Valley farmers, not from land following.
The Authority would pay an amount for the water that equals the cost of
conserving the water, plus an incentive to encourage participation by farmers.
The contract includes a formula to determine the water’s price that takes into
account the cost of MWD water. The water’s price reflects due diligence by the
Authority and IID to confirm the cost of on-farm conservation measures such as
pumpback systems and the lining of earthen irrigation canals. While the price
does not include the cost of conveying the water from the Colorado River to San
Diego County, it does account for both the estimated cost of wheeling the water
(the base wheeling rate) to San Diego County -as based on interpretations of
state law by the Authority and IID -and the actual wheeling cost which is being
negotiated with MWD. A discount is applied to the price that begins at 25 percent
in year one and declines gradually over 17 years to stabilize at 5 percent for the
remainder of the contract. (The discount on the transfer rate goes out of
r ‘1
existence once the rate is redetermined in the future based entirely on the price
of other similar transfer transactions; price redetermination is explained below.)
An example of the formula follows (the numbers used are only examples):
MWD untreated water rate
Other MWD charges
MWD “full rate”
Base wheeling rate
25 percent discount (year 1)
Year 1 price
$349/acre-foot
+ 51
400
- 68.50
331.50
- 82.87
$248.63/ate-foot
The contract also features a provision under which the Authority and IID
would share the difference between the estimated cost and the actual cost of
wheeling the water. In the example above, if the actual wheeling rate is $10 per
acre-foot higher than the estimated rate, the Authority and IID would split the $10
difference. The Authority would subtract its $5 from the $248.63 total, making the
transfer rate $243.63 per acre-foot.
Under the negotiated terms, either the Authority or IID may request a
redetermination of the water’s price after the first 10 years of the contract and no
sooner than every 10 years thereafter. Until the market for water transfers
reaches a maturity threshold, the price would be redetermined based on a
comparison with the cost of comparable transfers, Authority water supply
projects, and MWD’s water rates. Once the transfer market matures, the price
redetermination would be tied to the price of eligible water transfers in the Lower
Colorado River Basin. A mature market would have two primary defining
elements: There must be at least 10 eligible transactions, based on criteria
including reliability, legal and technical feasibility, quantity, location, duration and
water quality, and the annual volume of water transferred to California must
exceed a defined minimum amount. The goals of the price redetermination
process would be to ensure that the price of Authority-IID transfer water is
consistent with the water’s estimated market value and to limit as much as
possible the scope for arbitrary decision-making concerning price.
Water transferred under the agreement would result from IID’s Colorado
River rights, which are among the most senior In the Lower Colorado River Basin.
In recognition of the value added by this reliability, the contract requires the
Authority to pay a shortage performance premium to IID for transferred water if:
l The Authority declares a water shortage and imposes mandatory
conservation and rationing; or
l The State Water Project declares a critically dry year; or
l The Interior Department declares a shortage for the Lower Colorado
River Basin.
The premium would apply only while the transfer price is indexed to the
MWD water rate. Staff believes that while there is some probability of a shortage
premium being triggered prior to the first price redetermination based on historic
hydrologic conditions for the State Water Project and the Colorado River, existing
and planned regional storage programs, dry-year option agreements and the
availability of spot market water through the state’s drought water bank will
significantly mitigate this exposure.
Should the Secretary of the Interior declare a shortages in Colorado River
supplies, the Authority and IID would share the cutbacks proportionally. If IID
deliveries to the Authority represent 6 percent of IID’s total annual Colorado River
supplies, water transferred to the Authority would be reduced by 6 percent in a
shortage. IID would be responsible for any reductions in its quantified third priority
rights to Colorado River water. No shortage premiums would apply in such a
case.
The contract would go into effect in the first year after the Authority and IID
satisfy a series of contingencies. The state Water Resources Control Board and
the federal Bureau of Reclamation must approve the contract. The Authority must
arrange cost-effective and reliable conveyance for the water. (More on this in
section below headed “Wheeling negotiations with MWD.“) IID must have
participation by landowners representing at least 130,000 acre-feet of water per
year for the program. Both agencies must be able to reasonably mitigate
environmental impacts of the transfer. lid’s cost of environmental mitigation would
be limited to $30 million. The Authority’s environmental mitigation responsibilities
would be related to conveyance of the transferred water and would be limited to
$2 million.
Potential benefits of IID water conservation and transfer agreement The water
conservation and transfer agreement negotiated with IID offers several potential
benefits to San Diego County. In general, they relate to provisions of the
Authority’s Water Resources Plan regarding maintenance of an adequate and
reliable water supply for San Diego County. Water resulting from the agreement
negotiated with IID would represent a new, long-term and reliable supply for the
county that would help to meet increased future demand and serve as an
insurance policy against shortages caused by drought or other factors. As the
price of the transferred water would be set b- contract, its price would be stable
for planning purposes for a minimum of 10 years. Thereafter, the price would
remain competitive with the transfer market. In addition, the securing of a long-
term transfer would enable the Authority to diversify the county’s water supply -a
prime objective of the Water Resources Plan. The plan envisions a San Diegc
County supply in 2015 that gets 55 to 60 percent of its water from MWD, 15-20
percent from local resources and 25 percent from long-term transfers.
-
The water transfer agreement with IID also presents potential benefits for
the MWD service area and California. Water transferred from IID to the Authority
would expand the overall supply available to MWD and its member agencies,
which is especially important given that MWD stands to lose almost half of the
water it presently imports through the Colorado River Aqueduct. This would
relieve pressure on MWD’s limited Colorado River entitlements and help MWD
member agencies to have more secure supplies.
As to the state as a whole, an Authority-IID transfer of 200,000 acre-feet of
water per year is a key component of the plan being developed by the Colorado
River Board of California and Department of Water Resources Director Kennedy
regarding California’s future use of Colorado River water. Thanks to surplus
conditions, California takes about 5.3 million acre-feet of water per year from the
Colorado River -20 percent more than its allocation. Almost all of the use above
California’s 4.4 million acre-foot annual allocation goes to MWD, but the U.S.
Department of the Interior and the other Colorado River Basin states have
insisted that California develop and implement a plan to live within its allocation.
Development of such a plan may enable MWD to maintain access to surplus
supplies when available.
A transfer agreement between the Authority and IID also may benefit
California in several other ways. It potentially may strengthen the Southern
California economy by making San Diego County’s water supply more reliable
and stimulating the Imperial Valley’s economy. It could reduce Southern
California’s need for additional State Water Project deliveries from the
environmentally sensitive Bay-Delta system. It may help California avoid disputes
with other states regarding Colorado River water.
