[[Page 61798]]

Reclamation (Reclamation), the TRPA, and the California Tahoe 
Conservancy (Conservancy), intend to prepare a joint EIS/EIS/EIR. The 
EIS/EIS/EIR would evaluate a joint Reclamation and TRPA restoration 
project along the reach of the Upper Truckee River that extends from 
U.S. Highway 50 north to Lake Tahoe and its adjacent wetland. The 
purpose of the proposed action is to restore natural geomorphic 
processes and ecological functions in this lowest reach of the Upper 
Truckee River and the surrounding marsh to improve ecological values of 
the study area and help reduce the river's discharge of nutrients and 
sediment that diminish Lake Tahoe's clarity.
    The Upper Truckee River and Marsh Restoration Project is identified 
in TRPA's Environmental Improvement Program (EIP) as a project that is 
necessary to restore and maintain environmental thresholds for the Lake 
Tahoe Basin. EIP projects are designed to achieve and maintain 
environmental thresholds that protect Tahoe's unique and valued 
resources.
    Two public scoping meetings will be held to solicit comments from 
interested parties to assist in determining the scope of the 
environmental analysis, including the alternatives to be addressed, and 
to identify the significant environmental issues related to the 
proposed action.

DATES: The public scoping meeting dates are:
     Tuesday, October 24, 2006, 12 to 2 p.m., South Lake Tahoe, 
California.
     Tuesday, October 24, 2006, 6 to 8 p.m., South Lake Tahoe, 
California.
    In addition, the proposed project will be an agenda item at a TRPA 
Governing Board Meeting on Wednesday, October 25, 2006 in Stateline, 
Nevada (see agenda item at http://www.trpa.org/ 
default.aspx?tabid=258).
    All comments are requested to be received by October 31, 2006.

ADDRESSES: Scoping meetings will be held at the Inn By The Lake, Sierra 
Nevada Room, 3300 Lake Tahoe Boulevard, South Lake Tahoe, CA 96150.
    The TRPA meeting will be held at the TRPA Governing Board Rooms, 
128 Market Street, Stateline, NV 89449.
    Written comments on the scope of the environmental document, 
alternatives, and impacts to be considered should be sent to Ms. Jacqui 
Grandfield, Natural Resources Program Manager, California Tahoe 
Conservancy, 1061 Third Street, South Lake Tahoe, CA 96150.

SUPPLEMENTARY INFORMATION: 

Background

    The Upper Truckee River has been substantially altered by land 
practices during the past 150 years. Throughout its watershed, the 
river has experienced ecosystem degradation typical of what has 
occurred elsewhere in the Basin. The river has been modified from its 
original conditions by human activities, such as logging; livestock 
grazing; roads; golf courses; an airport; and residential, commercial 
and industrial developments. These conditions have resulted in 
increased sediment and nutrient loads discharging into Lake Tahoe from 
the river, which contribute to the declining clarity of the lake. Human 
influences have also resulted in reduced habitat quality for plant, 
wildlife, and fish species in the watershed. Restoration of natural 
processes and ecological functions of the river is an important part of 
the response to the decline in lake clarity.
    Restoration planning for the marsh began in the early 1990s with 
studies conducted by the University of California. In 1995, the 
Conservancy commissioned a restoration planning and design study, which 
identified a tentatively preferred river restoration concept 2 years 
later. However, it was determined that river restoration required use 
of the entire Upper Truckee Marsh and, at that time the east side of 
the marsh was not owned by the Conservancy; therefore, this tentatively 
selected concept could not be pursued. In 1998, the Conservancy began 
planning and design of an initial phase of wetland restoration on a 23-
acre portion of a study area located on the east side of the Upper 
Truckee River near Lake Tahoe. This is an area, called the Lower West 
Side Wetland Restoration Project (LWS), where the marsh had been 
previously filled during the construction of the adjacent Tahoe Keys. 
After careful investigations, planning, and design; extensive 
environmental review; and community outreach, the Conservancy approved 
restoration of 12 acres of wetland through fill removal as the LWS 
Project in 2001. Construction commenced in the summer of 2001 and was 
completed in the summer of 2003. In 2000, the Conservancy purchased 311 
acres of land in the center of the marsh from a private party, bringing 
nearly the entire Truckee Marsh into public ownership. Currently, the 
majority of the study area is owned by the Conservancy, including the 
marsh and meadows surrounding the lower reach of Trout Creek. 
Restoration concepts encompassing the whole marsh and the lower reach 
of the river could be developed after the acquisition. As part of this 
process, the Conservancy has also conducted public access and 
recreation use management planning for the river, marsh, and beach.
    Initially, the Conservancy defined project objectives and desired 
outcomes to direct the restoration planning process. A comprehensive 
evaluation and documentation of the existing natural processes and 
functions in the study area were conducted to begin the alternatives 
planning process. This evaluation enabled the identification of 
potential restoration opportunities and constraints. Armed with 
detailed information about the river and marsh processes and ecological 
functions, the Conservancy hosted a design charrette (i.e., interactive 
workshop) for agencies and other stakeholders to identify the spectrum 
of potentially feasible restoration ideas to be considered in the 
development of concept plan alternatives. Four alternative concept 
plans, all developed to be potentially feasible, were formulated to 
represent a reasonable range of restoration approaches. The four 
concepts generated by this extensive process are four action 
alternatives being evaluated in the EIS/EIS/EIR. A preferred 
alternative will be identified after public review of the alternatives 
and public comments are received on the Draft EIS/EIS/EIR.
    To date, key stages of the Upper Truckee River and Wetland 
Restoration project have included the following:
     Evaluating existing natural processes and functions of the 
Upper Truckee River and marsh in 2000 and 2001.
     Establishing project objectives and desired outcomes in 
2002, and updating them in 2005.
     Defining restoration opportunities and constraints in 2002 
and 2003.
     Conducting a restoration design charrette in 2003 to 
receive input from stakeholders on project priorities, concerns and 
constraints, and design ideas.

     Conducting hydraulic modeling studies to support the 
development and evaluation of project alternatives.
     Initial development and comparative evaluation of four 
conceptual restoration alternatives in 2004 and 2005.
     Regulatory agency review of alternative concepts for key 
issues and regulatory requirements in 2005.
     Further refinement and evaluation of the alternatives, and 
preparation of a Concept Plan Report (July 2006).

Project Objectives

    The following objectives were developed for the proposed action:
     Objective 1. Restore natural and self-sustaining river and 
floodplain processes and functions.
     Objective 2. Protect, enhance, and restore naturally 
functioning habitats.
     Objective 3. Restore and enhance fish and wildlife habitat 
quality.
     Objective 4. Improve water quality through enhancement of 
natural physical and biological processes.
     Objective 5. Protect and, where feasible, expand Tahoe 
yellow cress populations.
     Objective 6. Provide public access, access to vistas, and 
environmental education at the Lower West Side and Cove East Beach.
     Objective 7. Avoid increasing flood hazard on adjacent 
private property.
     Objective 8. Design with sensitivity to the site's history 
and cultural heritage.
     Objective 9. Design the wetland/urban interface to help 
provide habitat value and water quality benefits.
     Objective 10. Implement a public health and safety 
program, including mosquito monitoring and control.
    The following alternatives will be considered at an equal level of 
detail in the EIS/EIS/EIR:
     Alternative 1, Channel Aggradation and Narrowing (Maximum 
Recreation Infrastructure);
     Alternative 2, New Channel--West Meadow (Minimum 
Recreation Infrastructure);
     Alternative 3, Middle Marsh Corridor (Moderate Recreation 
Infrastructure);
     Alternative 4, Inset Floodplain (Moderate Recreation 
Infrastructure); and
     Alternative 5, No Project/No Action.
    Alternative 1 would include raising and reconfiguring a portion of 
the main channel, reconfiguring two sections of split channel, reducing 
the capacity of the river mouth, changing the hydrologic connectivity 
of the sailing lagoon, constructing a river corridor barrier to reduce 
wildlife disturbance, restoring sand dunes at Cove East, re-routing an 
existing recreational trail, and developing several new recreational 
components (i.e., full- and self-service visitor centers, pedestrian 
and bicycle trails, boardwalks, viewing platforms), an interpretive 
program, and signage.
    Alternative 2 would include excavation of a new channel and fill of 
a portion of the existing channel, constructing a new river mouth, 
changing the hydrologic connectivity of the sailing lagoon, 
constructing a river corridor barrier to reduce wildlife disturbance, 
and restoring sand dunes at Cove East, re-routing an existing 
recreational trail, constructing observation platforms, and developing 
an interpretive program and signage.
    Alternative 3 would include excavation of a new channel and fill of 
a portion of the existing channel, reducing the capacity of the river 
mouth, changing the hydrologic connectivity of the sailing lagoon, re-
routing an existing recreational trail, developing several new 
recreational components (i.e., self-service visitor center, pedestrian 
and bicycle trails, boardwalks, viewing platforms), and an interpretive 
program and signage.
    Alternative 4 would include excavation of portions of the meadow 
surface along the corridor of the existing channel to create an inset 
floodplain, reducing the capacity of the river mouth, constructing a 
river corridor barrier to reduce wildlife disturbance, (i.e., self-
service visitor center, pedestrian and bicycle trails, boardwalks, 
viewing platforms), and an interpretive program and signage.
    Under Alternative 5, existing conditions on the project site would 
be projected into the future.
    Potential Federal involvement may include the approval of the 
proposed action and partial funding of the river restoration component 
of the proposed action. The EIS will be combined with an EIR prepared 
by the Conservancy pursuant to the CEQA and an EIS prepared by the TRPA 
pursuant to its Compact and Chapter 5 of the TRPA Code of Ordinances.

Additional Information

    The environmental review will be conducted pursuant to NEPA, CEQA, 
TRPA's Compact and Chapter 5 of the TRPA Code of Ordinances, the 
Federal and State Endangered Species Acts, and other applicable laws, 
to analyze the potential environmental impacts of implementing a range 
of feasible alternatives. Public input on the range of alternatives 
proposed for detailed consideration will be sought through the public 
scoping process.
    The EIS/EIS/EIR will assess potential impacts to any Indian Trust 
Assets or environmental justice issues. There are no known Indian Trust 
Assets or environmental justice issues associated with the proposed 
action. Input about concerns or issues related to Indian Trust Assets 
are requested from potentially affected federally recognized Indian 
Tribes and individual Indians.
    Our practice is to make comments, including names, home addresses, 
home phone numbers, and e-mail addresses of respondents, available for 
public review. Individual respondents may request that we withhold 
their names and/or home addresses, etc., but if you wish us to consider 
withholding this information you must state this prominently at the 
beginning of your comments. In addition, you must present a rationale 
for withholding this information. This rationale must demonstrate that 
disclosure would constitute a clearly unwarranted invasion of privacy. 
Unsupported assertions will not meet this burden. In the absence of 
exceptional, documentable circumstances, this information will be 
released. We will always make submissions from organizations or 
businesses, and from individuals identifying themselves as 
representatives or officials of organizations or businesses, available 
for public inspection in their entirety.
