Notice of Availability of a Final Environmental Impact Statement/
Environmental Impact Report on the Bair Island Restoration and
Management Plan, Don Edwards San Francisco Bay National Wildlife Refuge
and the Bair Island State Ecological Reserve, San Mateo County, CA
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of Availability.
-----------------------------------------------------------------------
SUMMARY: This notice advises the public of the availability of the
Final Environmental Impact Statement/Environmental Impact Report (Final
EIS/EIR) for the Bair Island Restoration and Management Plan. The
Record of Decision will be signed no sooner than 30 days after this
notice.
The Fish and Wildlife Service (Service) and the California
Department of Fish and Game (CDFG) plan to restore to tidal action
1,400 acres of former salt ponds on Bair Island, a unit of the Don
Edwards San Francisco Bay National Wildlife Refuge (Refuge) and the
Bair Island State Ecological Reserve in South San Francisco Bay. The
restoration would involve breaching existing former commercial salt
pond levees, adding flow restricters to Corkscrew Slough, and adding
wildlife-oriented public use facilities. It could also include
rerouting Smith Slough to its former slough bed and raising the bottom
elevation of Inner Bair Island with dredge and/or fill material or
adding water control structures to Inner Bair Island.
DATES: The Environmental Protection Agency (EPA) notice officially
starts the 30-day waiting period for these documents. It is the goal of
the Service to have our notice published on the same date as the EPA
notice. However, if that does not occur, the date of the EPA notice
will determine the closing date for the Final EIS/EIR. The 30-day
waiting period will end on August 28, 2006. Written comments should be
received on or before this date.

SUPPLEMENTARY INFORMATION:
[[Page 42873]]
Background
Pursuant to the National Environmental Policy Act (NEPA), the
Service prepared a Final EIS evaluating the impacts of restoring and
managing up to 1,400 acres of former salt ponds to tidal wetland in San
Francisco Bay.
The Bair Island Complex is divided into three distinct areas
separated by slough channels: Inner, Middle, and Outer Bair. Inner Bair
Island is connected to the mainland with access from Whipple Avenue and
U.S. Highway 101. Inner Bair Island is separated from Middle Bair by
Smith Slough, which in turn is separated from Outer Bair by Corkscrew
Slough.
Historically, Bair Island was part of a large complex of tidal
marshes and mud flats within the drainage of San Francisco Bay, Redwood
Creek, and Steinberger Slough. Bair Island was diked in the late 1800's
and early 1900's for agricultural purposes. It was converted to
commercial salt ponds in 1946 and remained in production until 1965.
The lands were then drained and sold to a series of real estate
development companies. A local referendum in the City of Redwood City
halted development plans for Bair Island. The CDFG and the Refuge both
acquired portions of Bair Island over time. The Peninsula Open Space
Trust purchased the majority of the remaining portions of Bair Island
in 1999, and their interests were acquired by these agencies. Among
several other landowners still remaining on Bair Island, the San Carlos
Airport retains a portion of Inner Bair Island as a flight safety zone.
In addition, two easements exist on Bair Island, for the Pacific Gas
and Electric transmission towers and lines that run throughout the site
and for the South Bayside System Authority (SBSA) force main that runs
underneath most of the southern part of the levee on Inner Bair Island.
Pedestrians and bicyclists currently use the top of the Inner Bair
Island levee as a 3-mile loop trail with a \1/2\-mile trail cutting
across Inner Bair Island during the dry season. Portions of Middle and
Outer Bair Island are used for waterfowl hunting, but there is little
fishing occurring. Redwood Creek and to a lesser extent, Smith,
Corkscrew and Steinberger Sloughs, are popular recreational boating areas.
The goal of the proposed Bair Island Restoration and Management
Plan is to evaluate options to restore Bair Island to a tidal salt
marsh to provide habitat for endangered species and other native
wildlife, as well as to enhance the public's appreciation and awareness
of the unique resources at Bair Island. Once restored, the site will
assist with the preservation and recovery of both the California
clapper rail and the salt marsh harvest mouse. These two species were
listed by the Service as endangered on October 13, 1970.
The restoration of Bair Island would take place in phases. The
first phase would be breaching of Outer Bair Island at one location on
Steinberger Slough near its entrance to San Francisco Bay. The second
phase would be restoration of Inner and Middle Bair Island. The third
phase, which could take place during or after the first two phases,
would be the construction of wildlife-oriented public use facilities.
On March 27, 2000, the Service published a Notice of Intent to
prepare an EIS in the Federal Register (59 FR 16217). Scoping
activities included a public scoping meeting on April 27, 2000.
Comments received in response to this notice were incorporated into the
Draft EIS/EIR.
On August 27, 2004, the Service published a Notice of Availability
of the Draft EIS/EIR in the Federal Register (69 FR 52730). A public
meeting to accept comments on the draft document was held on September
22, 2004. In the Draft EIS/EIR, we proposed to restore 1,400 acres of
former commercial salt pond to tidal wetlands on Outer, Middle and
Inner Bair Island. Wildlife-oriented public use improvements were also
proposed. Project impacts were also described in the Draft EIS/EIR.
Development of the Final EIS
The Draft EIS/EIR was jointly developed with CDFG, which owns a
portion of the lands to be restored on Bair Island. All comments
received by either the Service or the CDFG are included and considered
in the Final EIS/EIR. A total of 31 comment letters were received from
organizations or individuals. The Final EIS/EIR incorporates all
changes or additions to the draft into one complete document.
The Analysis provided in the Final EIS/EIR is intended to
accomplish the following: Inform the public of the proposed action;
address public comments received on the Draft EIS/EIR; disclose the
direct, indirect, and cumulative environmental effects of the proposed
actions; and indicate any irreversible commitment of resources that
would result from implementation of the proposed action.
Alternatives Analyzed
The Final EIS/EIR considers five alternatives: A. No-Action
Alternative, Alternative 1: Tidal Marsh Restoration with Moderate
Public Access Alternative (Proposed Action), Alternative 2: Tidal Marsh
Restoration with Restricted Public Access Alternative, Alternative 3:
Tidal and Managed Marsh Restoration with Moderate Public Access
Alternative, and Alternative 4: Tidal and Managed Marsh with Restricted
Public Access Alternative.
Under the No-Action alternative, the Refuge would discontinue
ongoing levee maintenance and would not repair any levee breaks. The
Refuge would work with the San Carlos Airport and the SBSA to protect
their infrastructure on Inner Bair Island. The existing levees on
Middle and Outer Bair Island would eventually breach, causing unmanaged
tidal inundation of the ponds. This would result in several impacts to
existing infrastructure. There would be an increase in the
sedimentation rate of the Redwood Creek Shipping Channel, resulting in
the need for more frequent dredging by the Port of Redwood City. At
least in the short term, there would be an increase in the velocity
rate of the tidal waters at the junction of Smith Slough and Redwood
Creek, making use of the Pete's Harbor Marina more difficult. Ponding
of water on Inner Bair Island would increase the bird strike issue for
the San Carlos Airport. Approximately 1,400 acres of tidal salt marsh
would eventually be restored, but the No-Action Alternative would delay
restoration of the ponds to salt marsh by 20-100 years and, at least in
the short term, result in poorer quality endangered species habitat
being developed compared to the four action alternatives.
In the short term (approximately 5 years), the No-Action
alternative would provide limited public use consistent with protection
of wildlife habitat and public safety. In the long term (approximately
5 to 10 years), as the Inner Bair Island levee became unsafe, public
use of the 3-mile trail would be eliminated and the area would be
closed to public access. No additional public use infrastructure such
as wildlife viewing platforms and interpretive signage would be
installed, and the Bair Island parking lot would be closed.
In Alternative 1, the proposed action, the Tidal Marsh Restoration
with Moderate Public Access Alternative, full tidal salt marsh
restoration would occur on Outer, Middle and Inner Bair Island. The
levees on Middle and Outer Bair Island would be breached. Dredge and/or
fill material would be used to raise the elevation of Inner Bair Island
to prevent increasing the bird strike issue for San Carlos Airport.
Following dredge or fill material placement, the Inner Bair Island
levee would be breached, restoring the historic meander
[[Page 42874]]
of Smith Slough to prevent unacceptable tidal velocities at Pete's
Harbor Marina. A flow restricter would be installed in Corkscrew Slough
to prevent increased sedimentation of the Redwood Creek Shipping
Channel. Approximately 1,400 acres of tidal salt marsh would be
restored more quickly than would occur under the No-Action Alternative
for the endangered California clapper rail, salt marsh harvest mouse,
and other native wildlife.
A wildlife viewing platform with portage for small boats would be
constructed at the flow restricter in Corkscrew Slough. A 5-mile-per-
hour speed limit and no-wake zone would be implemented in Smith and
Corkscrew Slough to protect harbor seals and other sensitive wildlife.
In addition to waterfowl hunting, Refuge guided trips would continue to
be the only public access allowed on Outer and Middle Bair Island. On
Inner Bair Island, 1.8 miles of trails on the levee, which would end at
two wildlife platforms adjacent to Smith Slough, would replace the 3-
mile loop trail. A predator-resistant pedestrian bridge would be built
from the existing parking lot to Inner Bair Island. The parking lot
would be enlarged to accommodate school buses, a restroom and an
information kiosk. The Whipple Avenue entrance would be closed to
public access but maintained for emergency vehicle access. Pets (dogs
only) would be allowed on the Inner Bair Island trails on a 6-foot
leash. Future dog access to Bair Island will be determined during a
test period of compliance with Refuge regulations designed to protect
wildlife.
As a result of comments made on the Draft EIS/EIR, Alternative 1 in
the Final EIS/EIR differs from Alternative 1 in the Draft EIS/EIR in
the following ways: (1) The public access trail on Inner Bair Island
would be shortened from 2.7 miles to 1.8 miles; (2) a predator-
resistent pedestrian bridge would be added to directly connect the
existing Bair Island Parking Lot to Inner Bair Island; (3) a 3-foot
high berm or one strand fence would be added, to be placed between the
public access area and the restored habitat; and (4) the existing
parking lot would be enlarged to accommodate school buses, a restroom,
and an information kiosk.
Alternative 2, the Tidal Marsh Restoration with Restricted Public
Access Alternative, would be the same as the Preferred Alternative
(Alternative 1), except for the following: (1) No pets would be allowed
on Inner Bair Island; (2) there would be a seasonal closure to boating
in Corkscrew Slough to protect harbor seals; (3) no pedestrian bridge
would be built from the Refuge parking lot and the parking lot would
not be enlarged to accommodate school buses and a restroom; (4) an
existing unimproved trail on the mainland from the Refuge parking lot
to the Whipple Avenue trailhead would be improved, and Whipple Avenue
would continue to be used as the primary public access route to Inner
Bair Island; and (5) the 1.8-mile Inner Bair Island Trail would not
extend east of Whipple Avenue, but would extend further along Smith
Slough on the west side of Whipple Avenue, ending in one wildlife
viewing platform along Smith Slough. Approximately 1,400 acres of tidal
salt marsh would be restored more quickly than would occur under the
No-Action Alternative for the endangered California clapper rail,
endangered salt marsh harvest mouse, and other native wildlife.
Alternative 3, the Tidal and Managed Marsh Restoration with
Moderate Public Access Alternative, would be the same as Alternative 2
except for the following: (1) Inner Bair Island would not be restored
to tidal salt marsh; (2) Pets (dogs only) would be allowed on the Inner
Bair Island trails on a 6-foot leash for a test period to determine
compliance with Refuge regulations designed to protect wildlife; and
(3) there would not be a seasonal closure of Corkscrew Slough to
protect harbor seals. Using water control structures, managed salt
marsh would be created on Inner Bair Island, a flow restricter would be
built in Smith Slough to prevent an unacceptable increase in tidal
velocity at Pete's Harbor Marina, and the slough would not be restored
to its historic meander. Approximately 1,100 acres of tidal salt marsh
would be restored on Outer and Middle Bair Island more quickly than
would occur under the No-Action Alternative for the endangered
California clapper rail, endangered salt marsh harvest mouse, and other
native wildlife. Three hundred acres of managed salt marsh would be
created on Inner Bair Island for the endangered salt marsh harvest
mouse but no habitat would be created for the endangered California
clapper rail.
Alternative 4, the Tidal and Managed Marsh Restoration with
Restricted Public Access Alternative, would be a mixture of
Alternative's 2 and 3. The restoration of 1,100 acres of tidal salt
marsh and 300 acres of managed salt marsh on Inner Bair Island would be
the same as in Alternative 3. The public access would be the same as in
Alternative 2.
This notice is provided pursuant to regulations for implementing
the National Environmental Policy Act of 1969 (40 CFR 1506.6).
