Bayfront Trail Gap Closure Concept
PROJECT DESCRIPTION
The alignment for the trail gap closure concept extends 1,113 linear feet northerly from the proposed
project along the edge of the Bay from the vacant parcel at 1220 Bayshore Highway to the office property
at 1338 Bayshore Highway. The 12 -foot wide asphalt -concrete trail would be constructed on a raised
embankment with a rock riprap alone the shoreline for slope protection. The conceptual trail alignment
crosses a total of seven parcels including four commercial properties and three vacant parcels, including
easements for Easton Creek and the unnamed drainage channel from Highway 101. These properties
include, from north to south, an office building at 1338-40 Bayshore Highway, the Hyatt Cinema at 1300
Bayshore, the Ramada Inn at 1250 Bayshore (which includes the drainage easement for Easton Creek), an
office building at 1240 Bayshore, and a vacant lot (which includes the easement for the unnamed drainage
channel from Highway 101). The project also includes portions of a vacant parcel on the bayward side,
which largely consists of tidelands but which also includes a strip of upland along the shore.
SUMMARY OF IMPACTS AND MITIGATIONS
IMPACTS
lI8XOROt'S_'1
1. The use of heavy construction equipment or die
improper placement of material stockpiles could
result in potential slope failures and subgmde
damage.
(Potentially Significant Impact)
1. The following measures will be implemented to
avoid slope failures and subgrade damage:
Avoid the use of heavy equipment in project
grading and construction. The maximum equipment
sizes should be Cat D4 or equivalent for dozers and
Cat 943 or equivalent for track -wheeled loader.
Other equipment should be generally limited in
weight to approximately 10 tons per vehicle. Fully -
loaded scrapers should not be used.
Static compaction equipment without vibration
should be used.
In areas where the thickness of the existing fill has
been reduced (i.e., by excavation for the project),
light equipment should be used. Open excavations
in soft Bay Mud cannot support rubber -tired
equipment although light dozers with mud tracks
may be used.
No heavy equipment, stockpiles or other surcharges
should be allowed within 25 feet of the landward
embankment toe of slope.

IMPACTS
GEOLOGY (CONT'D)
2. The strong ground shaking expgcted at_ die trail
alignment during a moderate to severe earthquake
could potentially result in damage to structural
elements such as the bridges and die seawall
section.
(Potentially Significant Impact)
MITIGATION
To avoid damage during a major earthquake, the
bridges would be designed to Caltrans' seismic
standards and the seawall section would be designed
to withstand seismic loads, per the
recommendations of the geotechnical engineer at
the time of final design.
(Less -than -Significant Impact with Mitigation)
HYDROLOGY AND FLOODING
1. Unless mitigated, portions of the trail alignment
would be subject to flooding during die 100 -year
event.
(Potentially Significant Impact)
2. The embankment fills for the trail would be subject to
wave erosion which could ultimately result in
damage to tite trail and its support fills. (Potentially
Significant Impact)
1. To protect the trail from flooding and tidal action
during the 100 -year event, the trail would be
constructed at+10 feet NGVD to provide 3 feet of
freeboard above the 100 -year flood elevation of +7
feet NGVD.
(Less -than -Significant Impact with Mitigation)
2. The trail concept includes riprap shoreline protection
which would provide armoring against wave action
and prevent further shoreline erosion in the project
area.
(Less -than -Significant Impact with Mitigation)
BIOLOGICAL RESOURCES
The implementation of the trail concept would
result in the loss of approximately 0. 14 acres of
remnant salt marsli/mudflat habitat along the Bay
shoreline and drainage charnels in the area.
(Potentially Significant Impact)
i,
1. To compensate for the loss of wetland habitat, it is
likely that the Corps of Engineers and the resource
agencies would require the creation of
approximately 0.3 to 0.45 acres of replacement
habitat in the vicinity of the trail alignment.

•
Streets and parking areas subject to construction traffic will be damp swept
regularly such that all visible debris and soil is removed.
•
If grading and construction activity occurs during the rainy season, silt
fences, hay bales, and/or other measures will be employed along the
landward side of the embankment fills to prevent silt runoff into the
adjacent area.
•
Work within areas subject to tidal influence will be scheduled such that
each increment of excavation, fill, and placement of riprap will be initiated
and completed prior to the onset of the next tide event.
•
Silt fencing will be installed in certain areas at the project limits to provide
a protective barrier for adjacent wetland and habitat areas.
•
The placement of riprap along the banks of Easton Creek and the unnamed
drainage channel will be subject to a Section 1601-1603 Streambed
Alteration Agreement with the California Department of Fish and Game,
which would specify measures for controlling erosion in the channels.
For construction activities conducted during the rainy season, erosion
control practices will include the following additional measures:
Silt fences, bay bales, and/or other measures will be employed along the
landward side of the embankment fills to prevent silt runoff into the
adjacent parking areas.
Storm drain inlets will be protected by Tray bales or silt fences.
Additional erosion control measures may be required per the City of
Burlingame Storni Water Management and Discharge Control Ordinance.
All erosion control measures will be included in the construction contract
documents for the project.

CONSTRUCTION IMPACTS - NOISE
Noise levels would be temporarily elevated 1. The following measures will be implemented to mitigate
during grading and construction. construction noise:
(Potentially Significant Impact)
• To miiuwnize equipment noise, standard practices such as
proper muffling and maintenance of equipment will be
employed.
As required by the City of Burlingame Municipal Code,
the hours of grading and construction will be limited to the
hours of 7 AM to 7 PM on weekdays, 8 AM to 6 PM on
Saturdays, and 10 AM to 6 PM on Sundays.
• To minimize noise resulting from the placement of piles
for the bridge abutments, the piles will not be driven but
will be drilled and filled with reinforced concrete.
To minimize noise disturbance to guests at the Ramada
Inn, grading and construction in the vicinity of the hotel
will be expedited to the extent feasible.
These noise mitigation measures will be included in the
construction contract documents for the project
(Less -than -.Significant Impact with Mitigation)
(Note: If the trail segment through the Ramada site is
constructed in conjunction with construction at the hotel,
the hotel will likely not open for business. If so, then noise
impacts would not be a concern, and the final two
mitigations would not be necessary.)
