DATE: March 22, 2007
CONTENTS: Salton Sea Authority Plan for Multi -Purpose Project and Adopted
Salton Sea Authority Budget Administration and Preferred Altemative
July 2006 — June 2007
RECOMMENDATION:
1. Waive further reading and adopt Resolution No. 07- 20 .
2. By Minute Motion, appropriate $5,000 from the unobligated General Fund to the
Salton Sea Authority for community outreach programs.
EXECUTIVE SUMMARY:
The Salton Sea Authority has developed a plan for a multi -purpose project to restore and
revitalize the Salton Sea. The Authority has requested the Palm Desert City Council join
other Valley cities and organizations and approve the attached Resolution and appropriate
$5,000 from the unobligated General Fund for community information and education
outreach efforts.
BACKGROUND:
The proper management of the Salton Sea will provide an important benefit to the City of
Palm Desert as well as the entire Coachella Valley. Restoration and revitalization of the
Sea is critical to protect our quality of life, including air and water quality, as well as to
preserve the wildlife habitat, tourism, and recreational activities in the Coachella Valley.
The local plan is the result of technical research and analysis and represents a consensus
of the Authority's member agencies.
Given current and expected future conditions, the Authority has developed and is
advancing a combined multi -purpose revitalization/restoration project aimed at currently: 1)
Restoring the Sea as a nationally important wildlife refuge; 2) maintaining the Sea as a vital
link along the International Pacific Flyway; 3) reducing odor and other air quality problems
for re-establishing the Sea as a tourist destination and recreational playground; and 4)
revitalizing the Sea as a local economic development engine. These project objectives are
derived from and consistent with the Salton Sea Authority Board policy positions that were
enacted in October 2005, and reaffirmed at an Authority Board workshop meeting held in
CITY COUNCIL STAFF REPORT MARCH 22, 2007
RE: ADOPT RESOLUTION NO. 07-20 , A RESOLUTION OF THE CITY OF
PALM DESERT, CALIFORNIA, PROVIDING FINANCIAL ASSISTANCE AND
SUPPORT TO THE SALTON SEA AUTHORITY PLAN FOR MULTI -PURPOSE
PROJECT
April 2006. The Authority's proposed project design is also being considered as one of ten
alternatives contained in the separate Salton Sea Restoration Project studies being
conducted concurrently by the Resources Agency of the State of California and the U.S.
Bureau of Reclamation.
The Authority's project objective is to achieve the habitat restoration and air and water
quality goals set out in State and Federal Legislation while simultaneously meeting the
needs of the residents of the region, local property owners, and civic leaders in the
Coachella Valley. These interests desire a large sustainable recreational lake with reduced
odor that serves as a catalyst for regional economic development. This lake would also
provide critical habitat values as it has in the past.
In addition to consideration of a Resolution of support for the local plan, the Salton Sea
Authority has requested that the City of Palm Desert join other local cities to contribute
$5,000 for community information and education efforts. The Authority is conducting a
significant community outreach effort to inform and educate the public about the
Restoration Plan and the consequences of failures that introduce the potential for
significant negative impacts of our quality of life and public health, as well as the transfer of
water currently going into the Salton Sea to coastal urban communities. The request for
funding is to allow the Authority to conduct presentations before municipalities, trade and
civic groups, and non-profit clubs and organizations. The effort has already included a
direct mail flyer sent to residents and a 30 second public service announcement airing on
local television. Future plans include a video documentary on the Sea that will be aired
later this year.
Staff recommends that the City Council: 1) Waive further reading and adopt Resolution No.
07- ; and 2) appropriate $5,000 from the unobligated General Fund to the Salton Sea
Authority for community outreach programs.

� Figure ES-3 Conceptual Plan for Salton Sea Revitalization&Restoration Including Land-Use Plan for the
Authority's 300,000 acre Planning 8�Financing District Surrounding the Sea
7
Saltan Sea Authority Plan for Multi-Purpose Project
In addition to the features discussed above that are designed to address water quality
problems and the potential air quality concerns associated with exposed lakebed,a
plan for development of areas around the Sea has been prepared. The plan was
prepared to guide creation of"Seaside Villages" and the build-out of over 250,000
new homes with accompanying entertainment,recreational,retail and business
establishments within specified areas of the Authority's 300,000-acre planning and
financing district aYound the Sea.
The project has been developed to a conceptual level at this time. The conceptual
project features are discussed briefly below and in more detail in the main body of
this report. Greater details will be developed in concert with site-specific
environmental documentation and entitlements at the next stage of analysis. Exact
locations and facilities will be determined during these subsequent reviews and a site-
specific Environmental Impact Statement/Report (EIS/EIR) will be prepared.
Reviews of this documentation will involve numerous local, State and Federal
regulatory agencies.
In-Sea Barriers and Recircvlation Canal
Once the required environmental documentation permits and approvals are finalized
(including the permitting of one or more local rock sources),construction will begin
on the signature feature of the Authority project: an approximately 33.5-mile-long,
rock-fill,in-Sea barrier located as shown in Figure ES-3.This engineered structure
will separate permanently the present 360-sq.-mile Sea into two separate water
bodies,namely:
a) An outer 180-s�.-mile lake water s�stem.This outer water body will be held
at a relarively stable elevation so the shorelines of the two newly created lakes
and the interconnecting boating channel on the west shore will remain
unchanged as long-term inflows decrease. The water in the two joint-use
recreational/habitat lakes will be treated as required and circulated to
maintain recreational water-quality standards.The larger northern salt water
lake (140 sq.miles) will be maintained at ocean-like salinity (35,000 mg/L
salt), and the smaller southern estuary lake (40 sq.-miles) will be held at a
lower saliniry(20,000 mg/L salt).The south lake elevation (-228'msl) will be
held about 2 feet above the north lake (-230'msl) since a slight hydraulic
gradient is needed for circulating the water in both lakes in a continuous
counter clockwise loop for blending and aeration. An earthen channel will be
excavated along the east shore of the south basin to convey north lake water
to the south lake and to support the 12,000-acre saline habitat complex in the
south basin.A pumping plant will be built at the end of this channel to lift
the extracted and treated north lake water into the south lake to blend with
the Alamo and New River inflows.
b) An inner 180-sc�.mile habitat and salt de�osit area in the south end of the
current Sea.The wetted surface area of this inner water body will shrink and
its elevation will decline as inflows decrease over time.A salt-purge stream
from the north lake will be discharged into the inner basin after being used in
8
Executive Summary
the saline habitat complex. The purpose of this purge stream is to balance
salt inflows and outflows in the outer lake-water system. By sending salt to
the inner basin in this manner,the two lakes can be held at relatively
constant, controlled salinity levels. The lower inner basin will also serve as an
overflow basin in the event of storm events. Salt pond pilot projects
conducted at the Salton Sea indicate that as the shoreline inside the inner
basin recedes,hard-surface salt deposits 12-to-24 inches thick will form on
top of the old lakebed. The cement-like salt deposits will prevent blowing
dust. Other air-quality miugation techniques will be used if needed. A
permanent hyersaline brine pool will eventually form in the lower depths.
Construction of the in-Sea barrier will require the excavauon, sizing, transport,and
placement by bottom-drop barges of approximately 64 million cubic yards of rock.
The barrier will be built to seismic dam-design standards. This will require extraction
by suction dredges of appro�mately 20 million cubic yards of soft sediments so the
placed rock rests directly on the underlying stiff lacustrine clay deposits. The height
of the barrier will range from 15 to 50 feet (including 10 ft of freeboard) depending
on water depth.
Water Treatment Facilities
While investigations are on-going to better define treatment needs,it is currently
anticipated that water treatment facilities will include a bottom drain and treatment
system for removing and destroying hydrogen sulfide, ammonia, and other
contaminants from the 50-foot-deep saltwater lake.A second treatment plant will
remove phosphorus and other contaminants from the Alamo River inflows. The
lake-water circulation system is designed to changeout the larger saltwater lake's
water volume every four to five years. The circulation system will also serve to
increase oxygen levels and avoid stagnation in the saltwater lake,and reduce selenium
levels in the southern estuary lake. In concert these measures will improve overall
water quality and fish habitat and greatly reduce odors.
Whitewater, New and Alamo Rivers Wetlands
With the Authority's assistance, the Citizens Congressional Task Force is completing
the design and permitting and is beginning construction of a system of several
thousand acres of water treatment wetlands along the New and Alamo Rivers in
Imperial County. Similar wetlands are planned on Torres Martinez tribal land along
the Whitewater River. (These wetlands coupled with a stable,better qualiry lake
should significantly improve conditions for the Tribe and stimulate economic
opportunities.) Although designed primarily for improving water qualiry (i.e.,
removing silt,nitrogen and phosphorus and increasing dissolved oxygen levels),
these wetlands also provide significant wildlife habitat.
Habitat Enhancement Features
The Authority believes the greatest ecosystem benefit of its conceptual project
design is the retention of a 90,000-acre, 50-foot-deep lake that will be restored to
ocean-like salinity (35 g/L salt) and will be managed to maintain habitat-safe water
9
Saltan SeaAutbority Plan forMulti-Pur�o.re Project
qualiry. This restored saltwater lake will enhance the existing fishery and thus
reestablish an abundant food source for the fish-eating birds that have historically
resided at the Sea or migrated along the Pacific Flyway. The Authoriry project design
also includes a 12,000-acre saline habitat complex located in the south and a 1,250-
acre estuarine habitat complex near the mouth of the Whitewater River. In addition,
half of the 26,000-acre estuary lake located in the south basin and a 6,000-acre area in
front of the barrier across the north lake will be designated"habitat zones"in which
motorized watercraft will be prohibited.
Colorado River Water Storage Reservoir
IID seeks a storage reservoir within the district's water system. A storage reservoir
has been incorporated into the Authority Plan project design to provide for this
need. This faciliry will be created by constructing a second barrier in 30-foot of water
outside the initial barrier.The enclosed 11,000-acre area will create a 250,000 AF
storage reservoir creating wildlife habitat. In addirion, the reservoir will provide air
qualiry mitigation by covering areas that would otherwise have exposed sediments.
Park, Open Space, and Wildlife Areas
Park, open space,and wildlife areas around the Salton Sea will be preserved. These
areas include the Salton Sea State Recrearion Area (SRA, commonly referred to as
the State Park) and the Sonny Bono National Wildlife Refuge. While the Wildlife
Refuge will be preserved,it is envisioned that the boundaries of the Refuge will be
modified to match the newly created habitat features. The SR�provides camping,
fishing and boating opportunities and the Wildlife Refuge provides bird watching
opportunities.With five campgrounds totaling approxunately 1,600 campsites, the
SRA provides more public access points than any other single shoreline access area.
The estimated historic peak seasonal use of the SRA was approxirnately 660,000
visitors in 1961-62, and the last three years reveal evidence of a resurgence in public
attendance,with a doubling of the total number of visitors in that period to 275,000.
With improved water quality and habitat values at the Salton Sea,the recreation
experience at both the SRA and the Wildlife Refuge is expected to be significantly
improved.
Master Plan for Planning Districf around the Sea
In December 2005,the Authoriry released a Master Development Plan for the
300,000-acre planning district surrounding the Sea. Conceptual plans for creating
separate and distinct seaside villages incorporating smart growth and sustainable
development concepts have been developed. This plan could accommodate 250,000
new homes with associated entertainment,recreational,retail and business
establishments being built over the next 75 years on 78,000 acres (less than 25% of
the 300,000-acre planning district). Under this plan,over 50% of the land around the
Sea would remain as habitat,parks and open space;and 20%would remain as
farmland.This plan is shown in Figures ES-3 and ES-4 and is presented in greater
detail later in this report.

Salton Sea Authority Plan for Multi-Purpo.re Project
Cost Estimate, Financing Plan & Implementation
As shown in Figure ES-5,the total preliminary capital cost estimate is $2.2 billion for
all components of the current Authority Plan. The various individual components of
the overall project will be constructed in a phased manner over the next 20 years as
funds become available from Federal,State and local sources.
A significant portion of the capital costs of a locally supported Plan can be locally
financed through the funding mechanisms applied within the Authority's 300,000-
acre planning and financing district around the Sea. These local funding mechanisms
include a combination of: (1) the formation of tax-increment financing and benefit
assessment districts; (2) public land acquisitions,transfers,and sales; (3) developer
payments and impact fees;and (4) use of public-private partnerships for the
construction and operation of the treatment plants.
The balance of the required capital funding is presumed to come from State and/or
Federal sources. The State of California has historically funded major habitat
restoration and water projects from both voter approved bonds and general funds.
The Authority member agencies will work to have the Salton Sea included in future
State bond issues and future State ballot measures.At this time, the only known State
or Federal funding source is the $90 million that contractually has been (or will be)
paid into the Salton Sea Restoration Fund (SSRF� by the QSA parties under the 2003
State legislation. Another$150 million of QSA-related funding is possible should the
Resources Secretary determine that it is feasible to sell the balance of the mitigation
water earmarked for stabilizing the Sea until a restoration project is in place.As
shown in Figure ES-5, the best case is that facilities could be in place in time to
obviate the need for the last two years of mitigation water. If this happens,it would
add$70 million to the SSRF.There is also a water and parks bond measure on the
November 2006 ballot in California with $47 million earmarked for the SSRF and
another potential$100 million for wildlife habitat and water quality projects.
The in-Sea barrier in the Authority Plan project design should be constructed within
10 years and the water qualiry improvements necessary for returning the Sea to
recreational quality water standards can be achieved within 15 to 20 years. This
project implementation schedule is shown in Figure ES-5. Water system design&
operating flows at design-case conditions are illustrated in Figure ES-6.
Next Steps
The Authority Plan presented in this document has been developed to a conceptual
level. Specific project details and designs will be developed in concert with site-
specific environmental documentation and enridements at the next stage of analysis.
Exact locarions and facilities will be determined during those subsequent reviews and
a site-specific Environmental Impact Statement/Report (EIS/EIR) will be prepared.
Reviews of the plans, designs and environmental documentation will be
accomplished in concert with appropriate local, State and Federal regulatory
agencies.
