Intent To Prepare a Draft Supplement (DSEIS) to the Final
Environmental Impact Statement; Sacramento River Bank Protection
Project, Lower American River, California
AGENCY: U.S. Army Corps of Engineers, DoD.
ACTION: Notice of intent.
-----------------------------------------------------------------------
SUMMARY: The proposed action is the implementation of streambank
protection along the lower American River where erosion threatens the
integrity and reliability of Federal flood control levees which provide
flood protection to the Greater Sacramento Metropolitan Area. The
proposed action, developed cooperatively by a task force composed of
government agencies and local interest organizations, comprises a near-
term bank protection action and possible longer-term bank protection
actions. Near-term actions include bank protection at five critical
sites comprising 13,800 linear feet of streambank protection. Longer-
term actions may be taken at any location along the lower American
River where project flood control levees become threatened by bank
erosion. The proposed action is being implemented by the Sacramento
River Bank Protection Project, a continuing construction project
authorized by the 1960 Flood Control Act.
FOR FURTHER INFORMATION CONTACT:
Questions or comments regarding this DSEIS should be addressed to Mr.
Matt Davis, Planning Division, Corps of Engineers, 1325 J Street,
Sacramento, California, 95814-2922, ATTN: CESPK-PD-R, telephone (916)
557-6708. An issues-scoping meeting for this project will be held on
July 11, 1995, as described below.
SUPPLEMENTARY INFORMATION:
1. Proposed Action
The Corps of Engineers and non-Federal sponsors (The Reclamation
Board, State of California, and the Sacramento Area Flood Control
Agency) are proposing to implement streambank protection measures on
the lower American River, California. The purpose of the proposed
action to implement streambank protection measures is to ensure the
reliability of the lower American River Federal levees, while
preserving existing environmental values and other values that lead to
the river's inclusion in the Federal and State Wild and Scenic Rivers
systems and creation of the American River Parkway.
The proposed action is being implemented under the Sacramento River
Bank Protection Project (SRBPP). The SRBPP is a continuing construction
project of the Corps of Engineers authorized by the Flood Control Act
of 1960. The purpose of the SRBPP is to protect the existing levees and
flood control facilities of the Sacramento River Flood Control Project.
The proposed action on lower American River is within the project area
of SRBPP.
The area of the lower American River to be affected by the proposed
action consists of the reach of the river bounded by Federal levees of
the American and Sacramento River Flood Control Projects. This reach
extends upstream from the confluence with the Sacramento River in the
City of Sacramento about 11 miles (south bank) to 14 miles (north
bank), through the American River Parkway of Sacramento County. This
reach of the American River is a designated Recreational Zone
[[Page 36124]]
of a Wild and Scenic River under both the Federal and State Acts.
Since January 1994, the lower American River Task Force, comprised
of flood-control agencies, resource-management agencies, local
governments, and local interest organizations, has been developing the
foundation for a locally preferred alternative for a flood control
project along the lower American River. This task force is addressing
five related areas: streambank protection measures, levee design and
stabilization issues, infrastructure needs and alternative flows, a
floodway management plan, and opportunities for parkway improvements.
The environmental document noticed herein would address the task
force's proposed streambank protection measures. The streambank
protection action would protect the existing flood control levee system
but not provide for a greater level of flood protection. Solutions to
flood problems along the American and Sacramento Rivers in the greater
Sacramento area are being addressed separately by the Corps of
Engineers under the American River Watershed Project (DSEIS and
Supplemental Information Report to be released for public review in
summer of 1995).
The proposed action to be addressed in the DSEIS, developed by
consensus among the task force participants, comprises a near-term bank
protection action and possible longer-term actions. Near-term actions
include bank protection at five critical sites comprising 13,800 linear
feet of streambank. Bank protection construction at these five sites is
proposed to begin in 1997. Longer-term actions may be taken at any
location along the Federal levee system where levees become threatened
by bank erosion. Although some potential sites have been identified,
other eroding sites may develop during future floods. The document will
identify sites most likely to need treatment, the process to be used to
determine if treatments are needed, the expected approaches to
treatment, and the process to be used to determine the actual
treatments.
To shorten the time period between identification of treatment need
and actual treatment in the future, as encouraged by the President's
Council on Environmental Quality, the document will also provide a
programmatic impact assessment of possible future bank protection
throughout the lower American River project area. This assessment will
focus on common, expected, and cumulative impacts of bank protection.
Actual proposed actions in the future would be subjected to further,
site-specific environmental review under this overall assessment, as
provided for by NEPA. The selection of both sites and methods of
protection will continue to involve collaboration with flood-control
and resource agencies.
All bank protection actions will be followed by monitoring of
installation stability and development of vegetation and habitat
values. In addition to onsite mitigation, offsite mitigation may be
incorporated into the proposed action. Advanced project mitigation will
also be considered in the document.
2. Alternatives
Alternative bank protection measures for near-term and longer-term
actions will be considered in the DSEIS. Streambank protection measures
under consideration include both bank revetment and indirect measures
to reduce erosion threats to the levees. Alternative designs retain as
many environmental features of the proposed actions as possible, while
modifying features potentially having adverse hydraulic effects. The
bank protection design proposals are intended to provide a high level
of flood safety and to retain and recreate onsite as much aquatic and
riparian habitat value and visual quality as feasible. The preferred
designs employ well-vegetated, visually irregular surfaces composed of
soil and biotechnical materials overlying rock protection. Large woody
material will be placed in embayments where hydraulic forces allow, and
riparian vegetation will be established above the summer water level.
The diverse physical structures are expected to result in a diversity
of plant communities and habitat types. Construction methods will
ensure minimum disturbance of vegetation on the remnant flood plains
within the levees.
3. Scoping Process
``Scoping'' is the process of identifying the range of actions,
alternatives, and impacts to be evaluated in an environmental document.
The following activities will be used to assist the Corps in scoping
the DSEIS:
a. Concurrent with publishing this notice of intent in the Federal
Register, the notice of intent will be sent to public agencies,
organizations, and individuals known to have an interest in the
project. All interested parties are encouraged to respond to this
notice and to provide scoping comments and a current address if they
wish to be contacted about the DSEIS. Comments received from the notice
will be used in determining the scope of the DSEIS.
b. Potential environmental impacts of the proposed action have been
identified in the following areas: Aquatic, wetland, and riparian
habitats; fish and wildlife populations; channel hydraulics, bank
stability, and flood control safety; visual character, recreation
opportunity and use, and recreation safety; construction traffic, air
quality, and noise; construction water quality; and cultural resources.
The environmental document will examine impacts in these topic areas
and any other potentially significant effects identified in the scoping
process. The ``no-action'' alternative, allowing bank erosion to
proceed unimpeded, will provide the baseline for assessing impacts of
the proposed action and the other alternatives.
c. After the draft environmental document is prepared, it will be
circulated for a 45-day review period to all interested parties for
review and comment. A public meeting, documented through a transcript,
will be held to receive verbal and written comments. All written and
verbal comments will be considered and responded to in the subsequent
Final SEIS.
4. Scoping Meeting
The public is invited to assist the Corps of Engineers in scoping
this DSEIS. To facilitate this involvement, the Corps will hold a
public scoping meeting in Sacramento on July 11 at noon at the
Sacramento Public Library, first floor, 828 I Street. A transcript of
the meeting will be made. Individuals, organizations, and agencies are
also encouraged to submit written scoping comments; these must be
received by July 21, 1995.
5. Estimated Date of DSEIS
The DSEIS is scheduled to be made available to the public on
February 5, 1996.
Dated: June 28, 1995.
