♦ Provide uniformity of cost and access
♦ Accommodate long-term producers
♦ Within SAR Watershed
♦ Within MWD service area
♦ Pay equivalent ad valorem taxes
- Annexation applicant collects and pays what
would have been ad valorem property tax
received by OCWD before Prop 13
- Adds an additional approx. $30 -40/af to
pumping costs
z Annexation Policy is Related to
OCWD Management Policies
♦ Seek and develop programs/projects to meet
increased production needs
♦ Uniformity of cost and access to basin supplies
- Equal access to all
- All costs shared equally
♦ Annexing additional land into OCWD puts that
territory under the District's management policies
(however no pumping rights are obtained)
♦ Avoid legal adjudication process of pumping from the
groundwater basin

Subject: OCWD Coastal Groundwater Management Activities
Dear 41R an:
Thank you for the recent meeting where we were able to discuss current groundwater basin
management issues at the District. As discussed, the District is now in a position where we
have to modify how we manage the groundwater basin. A future management approach is
currently being developed in a collaborative manner with the cities and water districts we
serve.
I am also providing you a list of activities we have completed or are in the process of
completing to further protect the coast from seawater intrusion.
1. Constructed two new injection wells for the Talbert Seawater barrier in 2000 on our
property with an estimated 2.5 mgd of injection capacity.
2. OCWD recently awarded a $5 million contract to replace and increase the diameter of
3,000 feet of barrier supply pipeline along Ellis Avenue, install 1,500 feet of extended
pipeline, and construct two sets of new injection wells (6 casings total) at Harper Park.
These wells are expected to be operational in late 2003 and provide an estimated
6 mgd of additional injection capacity to the west end of the Talbert Barrier.
3. Completed the construction of Well 1-26 which consists of three casings that inject into
three separate aquifers. This well is located next to the Orange County Sanitation
District (OCSD) and the 405 Freeway, became operational in 2001, and is capable of
injecting up to 1.5 mgd.
4. This past summer we constructed two multi-depth monitoring wells (M43 and M48) to
investigate the potential for saline intrusion beneath the Newport Mesa. In addition the
District and Mesa Consolidated Water District (MCWD)jointly constructed monitoring

well COSM-2 to a depth of 1,100 feet with 10 separate screens. This well will be used
to evaluate sources of colored water that have affected MCWD wells 7 and 8.
5. Eleven new injection wells were constructed by OCWD at the Alamitos Barrier in 2000.
These wells became operational in 2001 and have increased injection capacity by 600
to 800 acre-feet/year. We are currently evaluating additional alternative ideas with the
Water Replenishment District of Southern California to further strengthen this
seawater barrier.
6. OCWD staff completed calibration of the groundwater basin flow model in 2000 and
has used the model to evaluate various basin management issues, including overdraft
vs. underflow to Los Angeles County, 2020 pumping/recharge conditions at different
overdrafts, mid-basin injection wells, inland wellfields, and seawater barrier
effectiveness. We have worked very closely with the City's consultant on developing
the model.
7. As part of the design of the Groundwater Replenishment (GWR) System, OCWD and
it's consultant, Camp Dresser & McKee Inc., developed a detailed groundwater flow
model of the Talbert Gap. This model was constructed to more precisely evaluate the
current and future Talbert Barrier injection requirements to control seawater. Like the
basin model, the development of the Talbert Gap model was supported by the City's
consultant.
8. Developed and extended an agreement with the Metropolitan Water District of
Southern California (MWD) to allow for imported in-lieu water deliveries (versus
groundwater production) during the summer months for coastal producers. The
agreement allows your city to turn off its wells during the summer months, when water
demands are at their highest, and receive MWD in-lieu supplies at the equivalent cost
of groundwater.
9. We recently developed a program that allows for coastal groundwater producers to
turn off their wells while inland producers increase their groundwater production. This
administrative program shifts groundwater production away from the coast while being
revenue and cost neutral to all parties involved.
10. Our Board and the OCSD Board recently approved the construction of the GWR
System. The project is approximately 60% designed and includes the construction of
eight additional injection wells. After completion in five years, the District will be able
to inject up to 35,000 afy into the Talbert Seawater Barrier.
11. In 2001 we developed an agreement with the City to allow the District to take 3 mgd to
8 mgd of MWD supplies from a pipeline in Adams Avenue for injection into the Talbert
Seawater Barrier. We recently awarded a $3.4 million contact to build the necessary
pipeline from our site down to Adams Avenue to receive the water.

12. In 2001 we processed an agreement with the City of Fountain Valley and constructed
the necessary facilities to allow the District to receive up to 5 mgd of NIWD supplies
though their system for injection into the Talbert Seawater Barrier.
13. The following graph indicates the amount of water we have injected into the Talbert
Seawater Barrier the past few years. The graph shows how the amount of water
injected into the barrier significantly decreased during the mid to late 1990s. This
decline was primarily due the general aging of our existing injection wells, which can
become clogged. We have implemented programs to ensure our existing seawater
barrier wells are regularly serviced to ensure they are injecting maximum amounts of
water.

I hope this information is helpful. Preventing seawater intrusion is one of the primary
objectives of this organization and the City should feel comfortable that we will do whatever
is necessary to accomplish such.
I look forward to working with your City in the future. When appropriate I can provide a
briefing to your City Council on groundwater basin issues.
Very truly yours,

Subject: "H"ITEM FOR OCTOBER 7, 2002, CITY COUNCIL MEETING—
REQUEST FOR DETERMINING THE PROCESS FOR
ADJUDICATING THE ORANGE COUNTYAQUAFIR
STATEMENT OF ISSUE:
As you know, the city of Huntington Beach has sued the Orange County Water District
because they would not subject their master plan to an EIR process. Formalization of
the Orange County Water District Master Plan would address the over drafting of the
AQUAFIR and minimize salt-water intrusion, both of which could adversely affect water
availability to Huntington Beach. The legal challenge by Huntington has had minimum
success and the Orange County Water District refuses to negotiate with Huntington
Beach to guarantee reasonable amounts of potable water to Huntington Beach.
Recent newspaper articles indicate that the Orange County AQUAFIR is indeed being
over-drafted, which in turn increases the chances of salt-water intrusion. The Water
District denied these two eventualities four years ago when Huntington Beach brought
them to their attention. Now they apparently agree but offer Huntington Beach no
reasonable solution.
One of the ways of dealing with such an inequity is called "adjudication." This is a
prolonged expensive legal process where a judge finally parcels out water quotas to the
appropriate parties. It is not the preferred strategy that a pumping city might use, but
the actions of the Orange County Water District leave us little choice.
RECOMMENDED ACTION:
p; The following motion is suggested. It is moved that the City Attorney investigate the
process of adjudicating the Orange County AQUAFIR so that the Council may take an
overt action in this regard at some point in the near future to guarantee reasonable
amounts of drinking water to the residents of Huntington Beach over the long term.
