SUPPLEMENTARY INFORMATION:
    1. Authorization. The proposed feasibility study was authorized 
under Congressional Resolution, which reads as follows:

    Senate Resolution, approved 25 June 1969, reading in part: 
``Resolved by the Committee on Public Works of the United States 
Senate, that the Board of Engineers for Rivers and Harbors, created 
under Section 3 of the River and Harbor Act, approved June 13, 1902, 
be, and is hereby requested to review the report of the Chief of 
Engineers on the Los Angeles and San Gabriel Rivers and Ballona 
Creek, California, published as House Document Numbered 838, 
Seventy-sixth Congress, and other pertinent reports, with a view to 
determining whether any modifications contained herein are advisable 
at the present time, in the resources in the Los Angeles County 
Drainage Area.''

    2. Background. Historically, the Los Angeles River is subject to 
flooding and two of the largest floods in recorded history occurred in 
the 1930s, causing both a substantial loss of life and property damage. 
During the latter 1930s and 1940s the Federal Government (U.S. Army 
Corps of Engineers) constructed the concrete flood control channel in 
the Los Angeles River to expedite movement of stormwater flows to the 
ocean for flood prevention, causing a complete loss of the natural 
hydrologic and hydraulic regime and the natural riparian environment. 
Development along most of the River is a mix of housing, industrial and 
commercial land uses that contribute to the overall degradation of the 
ecosystem. The City of Los Angeles, city residents, and other local 
agencies have expressed interest and support for a feasibility study 
that would evaluate the potential for restoration of the Los Angeles 
River's aquatic ecosystem.
    The entire Los Angeles River travels through a highly urbanized 
area

[[Page 72456]]

covering a distance of 51 miles beginning at the confluence of Bell 
Creek and Arroyo Calabasas Creek in the San Fernando Valley community 
of Canoga Park, located approximately 32 miles northwest of downtown 
Los Angeles. The River flows through San Fernando Valley and the Los 
Angeles Basin, in a southeasterly direction until it empties in to the 
Pacific Ocean in San Pedro.
    The general project area includes approximately one-half mile on 
each side of the 32-mile river corridor that begins at the confluence 
near Owensmouth Avenue in Canoga Park, and continues downstream to 
Washington Boulevard, near the northern boundary of the city of Vernon.
    The Corps and the City of Los Angeles have prepared and published a 
Programmatic Environmental Impact Report/Programmatic Environmental 
Impact Statement (PEIR/PEIS, April 2007) for the Los Angeles River 
Revitalization Master Plan (LARRMP). The LARRMP is intended to serve as 
a blueprint for restoring some of the River's ecological functions and 
toward improving the overall health of the watershed by implementing a 
variety of projects, including channel modifications, improvements to 
the River corridor, revitalized riverfront communities in key 
opportunity areas, recreational amenities such as parks and open space, 
pedestrian and bicycle trails, bridges, enhanced connector streets, and 
green space networks in River adjacent neighborhoods. Implementing 
LARRMP recommendations over the near-term planning period (5 to 20 
years) and the long-term period (20 to 50 years) constitutes the 
proposed action evaluated in the Programmatic EIR/EIS. However, since 
the PEIR/PEIS did not evaluate site specific ecosystem restoration 
opportunities, it will not serve as a decision document for the Corps 
(i.e., result in a project action).
    Although components of the LARRMP include opportunities for 
restoring a more natural riverine environment along the Los Angeles 
River, the FS/EIS/EIR to be prepared for the Corps' Los Angeles River 
Ecosystem Restoration Feasibility Study will provide the necessary site 
specific evaluations and detailed analysis for ecosystem restoration, 
including various alternatives for restoration of riparian and aquatic 
habitats and functions, and increased habitat values. The FS/EIS/EIR 
will also consider the goals and objectives identified in the LARRMP 
and where they might meet the requirements of the Corps of Engineers 
Federal planning guidance for ecosystem restoration. The Corps is the 
Lead Agency for compliance with the National Environmental Policy Act 
(NEPA) for the project, and the City of Los Angeles is the Lead Agency 
for compliance with the California Environmental Quality Act (CEQA).
    The purpose of the Los Angeles River Ecosystem Restoration 
Feasibility Study is to consider opportunities for ecosystem 
restoration along 32 miles of the river within the City of Los Angeles, 
from the Canoga Park area of the northwest San Fernando Valley, to the 
southwestern quadrant of Los Angeles, near the border with the City of 
Vernon. The Project will identify opportunities to: (1) Evaluate and 
assess the problems and needs associated with loss of riparian habitat; 
(2) formulate alternative measures for environmental restoration, 
develop viable alternatives, and identify the National Ecosystem 
Restoration (NER) Plan, which will provide maximum ecosystem benefits; 
and (3) identify opportunities for Corps involvement in restoring the 
functions and values of the River's ecosystem. Secondary benefits would 
include associated recreational, water quality, and community 
revitalization opportunities.
    3. Proposed Objectives. The following planning objectives were 
identified to direct formulation and evaluation of alternative plans 
that implemented within and/or adjacent to the Los Angeles River:
    a. Restore riparian and aquatic habitat within the 32-mile reach of 
the Los Angeles River within the City of Los Angeles, where feasible.
    b. Support the restoration of more natural hydrologic processes 
within significant reaches of the study area.
    c. Support the restoration of habitat in reaches contiguous to 
existing habitat corridors where connectivity can be reestablished. 
(Note: These existing habitat corridors will be specifically identified 
in later iterations of planning objectives.)
    d. Support the modification of hydrology and stream hydraulics to 
maximize infiltration and inflow, decrease peak discharges, and 
identify storage where available.
    e. Provide recreation where appropriate along the 32-mile river 
corridor.
    The Los Angeles River Ecosystem Restoration Study is being 
conducted in a watershed context. While not a watershed study, this 
Feasibility Study is attempting to identify opportunities to engage in 
collaborative efforts with others who are addressing ecosystem 
restoration and other related water resources needs within the 
watershed. Planning objectives that could be affected by collaborative 
efforts within the watershed include:
    a. Identify opportunities to store or redirect flood waters within 
the watershed to reduce water surface elevations and support the 
reestablishment of baseflow within the mainstem;
    b. Identify opportunities to reestablish riparian corridors on 
tributary streams and to link sites to mainstem restoration sites;
    c. Identify areas for open space and recreation;
    d. Identify opportunities for groundwater recharge;
    e. Identify opportunities for water quality treatment/enhancement 
of mainstem inflows.
    4. Planning Constraints. Consistent with these planning objectives, 
the Los Angeles River Ecosystem Restoration Study will be formulated in 
recognition of a variety of planning constraints, which include:
    a. Restoration alternatives cannot degrade the existing Corps flood 
risk management project.
    b. Velocity reductions in the main river channel must be offset 
with measures that will provide additional flood storage capacity or 
the means to reduce flood flows to a level that will allow for riparian 
and/or aquatic restoration.
    c. The highly urbanized nature of the floodplain, competing land 
uses, and Corps policies limiting land acquisition costs (as a 
percentage of total project costs) will constrain the opportunities for 
acquisition of additional lands for floodplain restoration. Potential 
restoration locations will need to be identified opportunistically, 
based in large part on the availability of lands and the ability to 
acquire significantly sized parcels of floodplain lands.
    d. Existing infrastructure (roads, highways, utilities) adjacent to 
the waterway limits the physical extent of restoration activities.
    e. Potential restoration sites with unresolved hazardous, toxic and 
radioactive waste (HTRW) problems would be avoided.
    f. Public safety is primary concern for persons living adjacent to 
the Los Angeles River.
    g. Avoid conflicts with other legitimate uses of re-developable 
floodplain lands (e.g., active recreation).
    Based on the objectives and constraints, the FS/EIS/EIR would 
evaluate potential alternatives, including the proposed action and the 
no action alternative, and associated impacts for environmental 
resources (beneficial and adverse) on the

[[Page 72457]]

environment along the 32-mile river corridor.
    5. Alternatives. The FS/EIS/EIR will consider a range of viable 
alternatives and their impacts, including the No Action Alternative. 
The range of viable alternatives may include a locally preferred 
alternative or features that are improvements or measures desired by 
the project non-Federal sponsor (City of Los Angeles) that is not part 
of the Federal project. The Scoping will be an early and open process 
designed to determine the issues and alternatives to be addressed in 
the Report. Four initial sites within the general study area have been 
identified by the City and Corps:
     Portions of the Los Angeles State Historic Park.
     Glendale Narrows/Taylor Yard Reach.
     Sepulveda Basin.
     Reseda Park.
    These initial sites appear to have the greatest likelihood at this 
time to be readily-implementable, where alternative plans could be 
developed and implemented to meet the study's purposes. Additional 
sites may be identified during the scoping process and development of 
the draft FS/EIS/EIR. A range of alternatives will be developed for the 
sites identified and may include (but not be limited to) the following 
features or measures as applicable for each site:
     Water Storage.
     Widen Channel.
     Offline Channel.
     Create Pervious Surfaces in Watersheds.
     Tributary Reconfiguration/Restoration.
     Remove Concrete.
     Reconfigure Concrete.
     Connect Riparian Corridors to Existing Corridors.
     Create Riparian Corridors to Woodlands.
     Daylight Outfalls.
     In-channel Vegetation.
     Habitat Wetlands.
     Water Treatment Wetlands.
     Bio-engineering Channel Walls.
     Real Estate Acquisition (non-structural measure).
     Local Water Conservation Program.
     Community Education Programs.
     Establish Community Programs.
     Habitat Management Plan.
    6. Content of the Report. The FS/EIS/EIR will identify the 
anticipated effects of the project alternatives (negative and 
beneficial) and describe and analyze direct, indirect, and cumulative 
potential environmental impacts of the project alternatives, including 
the No Action Alternative, in accordance with NEPA (40CFR1500-1508) and 
CEQA. For each issue listed below, the FS/EIS/EIR will include a 
discussion of the parameters used in evaluating the impacts as well as 
recommended mitigation, indicating the effectiveness of mitigation 
measures proposed to be implemented and what, if any, additional 
measures would be required to reduce the impacts to a less-than-
significant level. The list of issues presented below is preliminary 
both in scope and number. These issues are presented to facilitate 
public comment on the scope of the FS/EIS/EIR, and are not intended to 
be all-inclusive or to be a predetermination of impact topics to be 
considered.
    Biological Resources. The Report will address the following issues 
and potential detrimental and beneficial effects related to biological 
resources:
     Increased habitat for all organisms that use multiple 
wetland and/or aquatic habitats, including birds, mammals, and fish;
     Improved habitat connectivity within the riparian habitat 
and adjacent upland habitats;
     Effects on habitat potentially supporting populations of 
endangered species and other species of concern;
     Shifts in geographic distribution of populations and 
effects on population sizes of migratory waterfowl and shorebirds;
     Effects of flood control structures on existing ecosystem 
attributes and functions including aquatic and terrestrial species; and
     Effects of public access and recreation on aquatic and 
terrestrial species.
    Hydrology and Flood Protection. The FS/EIS/EIR will address the 
following issues and potential detrimental and beneficial effects 
related to hydrology and flood protection:
     Existing and future without-project flood hazards;
     Changes in channel geometry and characteristics as a 
result of ecosystem restoration alternative measures; and
     Effects on flood flow conveyance as a result of ecosystem 
restoration alternative measures.
    Water Quality. The Report will address the following issues and 
potential detrimental and beneficial effects related to water quality:
     Engineering design and techniques to improve water quality 
in segments and throughout the project area;
     Effects of proposed ecosystem restoration alternative 
measures on base flow water quality.
    Recreation and Public Access. The Report will address the effects 
of ecosystem restoration alternative measures on existing recreation 
facilities and their use as well as the potential effects of ecosystem 
restoration measures on planned or new facilities. The benefits and 
impacts of increased or decreased public access on biological resources 
and achievement of other project objectives will also be addressed.
    Economics. The Report will evaluate the economic effects of the 
alternatives, including a cost effectiveness and incremental cost 
analysis of proposed restoration features, and a benefit-cost analysis 
of any flood control or recreation features.
    Cumulative Impacts. The Report will examine the cumulative impacts 
of past, ongoing, and reasonably foreseeable future projects affecting 
the Los Angeles River riparian corridor, as well as effects on adjacent 
urban and rural lands and communities.
    7. Environmental Analysis Process. The FS/EIS/EIR will be prepared 
in compliance with NEPA and Council on Environmental Quality 
Regulations, contained in 40 CFR parts 1500 -1508; and with CEQA, 
Public Resources Code Sec 21000 et seq., and the State and City CEQA 
Guidelines as amended. The Corps will be the Lead Agency for the NEPA 
process and the City of Los Angeles will be the Lead Agency for the 
CEQA process. In accordance with both CEQA and NEPA, these Lead 
Agencies are responsible for the scope, content, and legal adequacy of 
the document.
    The scoping process will include the opportunity for public input 
through written comments submitted during the 30-day scoping period. A 
public scoping meeting will also be held to solicit comments on the 
environmental effects of the range of potential actions and the 
appropriate scope of the FS/EIS/EIR.
    The draft FS/EIS/EIR will incorporate public concerns associated 
with the project alternatives identified in the scoping process and 
will be distributed for at least a 45-day public review and comment 
period. During this time, both written and verbal comments will be 
solicited on the adequacy of the document. The final FS/EIS/EIR will 
address the comments received on the draft during public review and 
will be made available to all commenters on the draft Report. Copies of 
the draft and final reports will be posted on the Internet as part of 
the public review process.
    The final step in the Federal EIS process is the preparation of a 
Record of Decision (ROD), a concise summary of the decisions made by 
the Corps. The ROD will identify the alternative selected and other 
alternatives that were considered. It also will discuss the mitigation 
measures that were adopted.

[[Page 72458]]

The ROD may be published no earlier than 30 days after publication of 
the Notice of Availability of the final EIS. The final step in the 
State EIR process is certification of the EIR, which includes 
preparation of a Mitigation Monitoring and Reporting Plan and adoption 
of its findings, should the project be approved.
    8. Scoping Process. Participation of affected Federal, State and 
local resource agencies, Native American groups and concerned interest 
groups/individuals is encouraged in the scoping process. Public 
participation is important in defining the scope of analysis in the FS/
EIS/EIR, identifying significant environmental issues and impact 
analysis in the FS/EIS/EIR and providing useful information such as 
published and unpublished data and personal knowledge of relevant 
issues.
    The Corps and City of Los Angeles conducted a public scoping 
meeting on April 18, 2007 for both the Feasibility Study and the LARRMP 
PEIR/PEIS (2007). Public input and comments received during the scoping 
meeting as well as other comments received during public outreach 
efforts associated with the LARRMP will be considered during 
preparation of the FS/EIS/EIR.
    A second public scoping meeting will be held on December 4, 2008, 
from 7--8:30 p.m. at the Metropolitan Water District, 700 North Alameda 
Street, Los Angeles, CA 90012, to solicit additional comments on the 
environmental effects of the range of potential actions and the 
appropriate scope of the FS/EIS/EIR. The public is invited to comment 
on environmental issues to be addressed in the FS/EIS/EIR during this 
meeting. Public input and comments received during the scoping meeting 
will be considered during preparation of the FS/EIS/EIR.
    Those interested in providing written comments, information, or 
data relevant to the environmental or social impacts that should be 
included or considered in the environmental analysis can furnish this 
information by writing to the point of contact (see ADDRESSES). 
Requests to be placed on the mailing list for announcements and the 
Draft FS/EIS/EIR also should be sent to Ms. Bostwick (see ADDRESSES).
