Development Act of 1986, will address
channel modification opportunities to
Unit 4 of Corte Madera Creek, Marin
County, CA. The purpose of the Corte
Madera Creek Flood Control Project is to
provide flood risk management for Corte
Madera Creek, from the upstream end of
the existing Unit 3 concrete channel to
Sir Francis Drake Boulevard at the
border of Ross and San Anselmo.
Although Units 1, 2, and 3 channel
modifications were completed in 1971,
public concerns led to a delay in the
planned actions for Unit 4. In 1996,
Marin County requested the completion
of Unit 4 by the Corps, and damages
incurred by the December 2005 flood
have also renewed public interest in
finding solutions to minimize the risk of
future floods. Since 1971, additional
technical studies were conducted that
provide another opportunity to
formulate and review new alternatives
in order to complete the project. This is
a notice of intent to prepare a joint
Environmental Impact Statement/
Environmental Impact Report (EIS/EIR)
to consider all reasonable alternatives
and to evaluate potential impacts
associated with the proposed actions.
The U.S. Army Corps of Engineers is the
lead agency for this project under the
National Environmental Policy Act
(NEPA) and Marin County Flood
Control and Water Conservation District
Zone 9 is the lead agency under the
California Environmental Quality Act
(CEQA).
DATES: A public scoping meeting will be
held on July 23, 2008, from 7 p.m. to 9
p.m. Written comments from all
interested parties must be received by
August 6, 2008.
ADDRESSES: The scoping meeting will be
held at the Drakes Landing Community
Room, 300 Drakes Landing, Greenbrae,
CA 94904.

proposed action and NEPA aspects of
the study can be addressed to Ms.

area, recent development of technical
studies, and some of the alternatives
that will be addressed in this study.
1. Background. Corte Madera Creek
drains an area of approximately 28
square miles in Marin County, CA, and
discharges into the San Francisco Bay
just nine miles north of the Golden Gate
Bridge. Units 1, 2, and 3 extend from
San Francisco Bay through the
communities of Corte Madera, Larkspur,
Kentfield, and Ross. Unit 4 extends from
the Lagunitas Road Bridge, near the
upstream terminus of Unit 3, to the Sir
Francis Drake Boulevard Bridge right
before the Ross/San Anselmo town line.
The project was originally authorized in
1962 and construction for Units 1, 2,
and 3 were completed by 1971. Unit 4
of the original project was not started
due to a series of design changes,
transfer of district ownership, property
litigation, and lack of public support.
Unit 3 was built so that it could be
modified with the future design plans of
Unit 4, such that changes to the Unit 3
channel would also be evaluated if
implementation of project construction
in Unit 4 caused flooding downstream.
The Corps has conducted additional
studies focused on evaluating the design
performance of Units 3 and 4 since
1971. These studies have identified the
unsmooth transition between Units 3
and 4 created by the existing Denil fish
ladder, the narrow channel condition on
the east and west bank, and the
Lagunitas Road Bridge as constrictions
to flood flow. The replacement of
Lagunitas Road Bridge is an option that
is being evaluated by the Town of Ross
and is not currently part of this federal
project.
The following proposed action seeks
to address the issues associated with the
current channel capacity of Unit 4.
2. Proposed Action. The U.S. Army
Corps of Engineers and the Marin
County Flood Control and Water
Conservation District propose to manage
flood risk along Corte Madera Creek,
downstream of Sir Francis Drake
Boulevard. The proposed action may
include changes to the existing design of
Unit 3 to ensure a total project design
capacity. The alternatives evaluated will
be developed in consideration of fish
passage for threatened and endangered
fish species that migrate through the
project area.
3. Project Alternatives. The following
represent a minimum of the alternatives
that will be evaluated in the EIS/EIR
regarding the proposed project to
increase flood flow capacity, in addition
to considering the improvement of fish
passage and bank stability in Corte
Madera Creek. The possibility of hybrid
PO 00000
Frm 00035
Fmt 4703

alternatives representing a combination
of measures will also be evaluated:
a. No action. Under this alternative,
the current conditions would be
retained at Units 3 and 4, and flood
capacity would remain unchanged at
approximately 3,200 cfs (cubic feet per
second). Under these existing
conditions, excess flood flows would
pass outside the channel onto a
residential floodplain. The no action
alternative would be considered as a
baseline in evaluating other alternatives.
b. Minimum action. This alternative
addresses the existing Denil fish ladder
which exacerbates flooding in the Unit
4 channel and is inadequate for fish
passage. The existing ladder would be
replaced with a concrete pool-and-chute
fish ladder, with a proposed location
within the upstream length of the Unit
3 concrete channel. Other design
considerations include meeting current
fish passage criteria as established by
NOAA’s National Marine Fisheries
Services (NMFS) restrictions on the
height of vertical leaps. The estimated
flood flow capacity of Unit 4 would
depend on the design of the
replacement fish ladder.
c. Unit 4 structural design alternative.
In addition to the minimum action,
flood risk management measures
proposed for Unit 4 include (1)
Installing vertical wall configurations
that would widen the channel and
increase the maximum flood flow
capacity to approximately 5,100–5,400
cfs, depending on the specific design;
(2) constructing a bypass culvert
adjacent to Lagunitas Bridge that would
convey high flows from the bridge to the
beginning of the concrete channel, with
capacity ranging from 300–1,300 cfs
depending on the type of culvert
structure; (3) installing temporary or
permanent low floodwalls or landscape
berms; (4) enlarging the sediment basin
immediately downstream of Lagunitas
Bridge, which would decrease the water
surface profile downstream and increase
flood flow capacity; (5) creating a
natural channel bottom with natural
grade protection that would
accommodate a flow rate of
approximately 5,400 cfs; and (6)
implementing grade control in order to
stabilize the stream bottom.
d. Unit 3–4 structural design
alternative. Measures that are proposed
to modify the junction between Unit 3
and 4 include (1) Replacing the existing
fish ladder with a natural grade
roughened rock channel between the
Unit 3 and 4 transition, which would
allow for fish passage while increasing
flood flow capacity to 4,900 cfs and
improving conveyance into the existing
concrete channel; (2) bank regrading

and use of biotechnical bank
stabilization techniques involving such
natural materials as native vegetation,
logs, and woody debris; and (3)
installing concrete wing walls to
facilitate flood flows into the stream
channel.
e. Non-structural alternative. The
non-structural plan would include
expanding the existing floodplain by
moving residential property through
real estate acquisitions.
4. Environmental Considerations. In
all cases, pursuant to NEPA and CEQA
guidelines, environmental
considerations will include human
health, riparian habitat, improving fish
passage and fish habitat, geophysical
impacts, air quality, hazards, noise,
utilities and service systems,
transportation, land use and planning,
historic and cultural resources,
aesthetics, recreation, social and
economic effects, as well as other
potential environmental issues of
concern.
5. Scoping Process. The Corps and the
Marin County Flood Control and Water
Conservation District is seeking
participation of all interested federal,
state, and local agencies, Native
American groups, and other interested
private organizations or individuals
through this public notice. The public
scoping meeting will be held in
Greenbrae, CA (see DATES). Any changes
to the date, time, or location will be
published in the local newspaper or
provided by mail to those requesting
information. The purpose of this
meeting is to solicit comments and
questions regarding the potential
impacts, environmental issues, and the
alternatives that should be discussed in
the EIS/EIR. Public participation will
help define the scope of the
environmental analysis, identify other
significant issues, provide other relevant
information, and recommend mitigation
measures, where possible. The public
comment period closes on August 6,
2008.
6. Availability of EIS. The public will
have an additional opportunity to
comment on the proposed alternatives
after the draft EIS/EIR is released.
