EXHIBIT B - NEGATIVE DECLARATION
Page 2
The City of Burlingame.by WAYNE M. SWAN on May 12, 1978 ,
completed a reyiew of the proposed project and determined that:
( ) It will not have a significant effect on the environment.
�( X) No Environmental Impact Report is required.
Reasons for a Conclusion:
Restaurant uses are compatible and consistent wi.th the General Plan. Waterfront
Commercial land use is shown on the General Plan at the project site. Concept plans
satisfy'building, fire and zoning regulations except for the compact car spaces. An
alternative parking layout could be used to provide 30 more standard size par.king spaces
and avoid the variance but it would reduce the landscaping to 15% of the site and result
in a less attractive and less functional project. The chanc�es required would be as
fol l ows :
. (1) Convert the 13 compact spaces behind the building to landscaping; and reduce
existing landscaping for more parking;
. (2)�Push the parking lot closer to Airport Blvd. and convert 19 compact spaces
to 17 standard size spaces; ,
(3) Drop the entry plaza and the end-of bay planters to gain 6 spaces;
(4) Push the parking 1ot 9' closer to Bayview�Place to gain 4 spaces; and
(5) Remove landscaping along north property. line to gain 3 spaces.
The net change would reduce the amount of parking by two spaces and reduce the landscaped
area by nearly 3,700 SF.
The Open Space Element of the General Plan shows street righis-of-way and "adjacent
front yards" along Bayshore Highway and Airport Blvd: as street space. Wide landscaped
berms around the street frontage wili screen the open parking area from the adjacent site.
Four Seas Center will occupy a prominent corner. This intersection will become a major
point of entry for northbound traffic along Bayshore Freeway destined for Anza Shareholders'
Liquidating Trust:territory. When the buttonhook freeway ramp is constructed, access to
the project site will be enhanced. '
� A reasonable standard for office buildings which require more than 50 parking spaces
is�to allow up to 20q of the total required spaces to be for compact cars. For a mixed
occupancy project the guideline might be 15 or 16% of the total parking requirement.
The first 20� might be standard size spaces and then 20% of the balance could be compact
spaces. For this project this would mean.that the first 20% (37 of 185) should be full
size and 20% of the balance (30 of 148} could be of compact size.

EXHIBIT Q- NEGATIVE DECLARATION � Page 3
The proposed projeet parking layout has been designed and balanced to serve the �
mixed uses by time, provide the numbe,r of parking spaces required and allow a reasonable,
realistic mix of compact spaces. � . �
Traffic to and from this prominen�t corner site will have two driveways; one on
Airport Blvd. and the other on.Bayview Place. This affords operational flexibility, with
the possibility of a signalized intersection. Truck access is simplified. On-site
loading/unloading can take place behind the building Tn �the rear driveway. Projeci
sponsors made off-site modifications to the median planter in Airport alvd. to include
lanes for left turn movemerits to and from the project parking lot. �
The existing water distribution system has sufficient capacity for the proposed
project. The existing wastewater lift station has sufficient capacity and creates no
new unanticipated sewage load at the treatment plant. Pollution from storm water runoff �
will be mitigated by�the installation of a pit-type clarifier which combines sedimentation
and skimming action. .
� The impact of iraffic generated by the proposed office/restaurant project can be
mitigated by staggered work hours and flexible working time, transit and car pools and
mixed occupancy. Space used by restaurants will generate traffic at different times
than office uses. �
The Bayfront Alternatives under consideration.in land use studies all show office use
at the project location. The concurrent Bayfron.t Traffic Study�has assumed office use
for projecting traffic generated by this 1.74 acre site. It is estimated that 140
permanent employees will work at Four Seas Center.
Three study area permits have been approved for restaurant uses on neighboring sites,
one being at the end of Bayview Place. Notices of Exemption or Negative Declarations
have been prepared and -posted for each of these three restaurants. The proposed project
will be tall but it will not have the appearance of a solid building.. It will be possible
to see through the parking garage. The fifth floor restaurant will have a magnificent
view of San Francisco, the Bay and the Burlingame backdrop of wooded hills and the
San�Francisco watershed. � �
Sign�ficant project effects can be mitigated by sharing in the cost of circulation
system improvements ar�d future traffic signals at the intersection. Economic, social
and physical benefi�s will accrue to the City. This unusual project will become an
attractive asset for the City of Burlingame.

DESCRIPTION OF PROJECT

PROJECT DESCRIPTION
J
It is proposed to construct on Lots 2 and 3 in Block 1 of �'Anza
Airport Park Unit No. 4", Burlingame, California, a five-story
office, restaurant, and parking complex. The office and restaurant
facilities shall be located above two levels of parking �aithin the
structure; additional parking being on the surrounding site.
�
The basic concept of the building is the stepping-out of each floor
£rom the one beneath it. This serves several functions. It
increases the floor area where it is most desirable; that being as
one gets higher within the building. The uppermost and consequently
l.argest floor is devoted to restaurant use which brings a higher
> return per_ square foot than does the office space.
In addition, this type of scheme utilizes.more efficiently those
functions at ground levQl, such as parking and circulation, since
buffers do not need to be created between these and occupiable office
space.
9
The first two levels of the structure are devoted to parking. The
lowest being depressed approximately'two feet below existing grade.
� This lowest level of cars is screened from view by a landscaped berm.
The second level of parking is above eye level and its cars are
screened by a precast concrete parapet. Therefore, one can at grade
J level virtually look "through" the building at the bay and not be at
� all aware of the fact that the building sits above a parkin.g struct�re.
The freight elevator servicing the top floor is accessible froin the
lowest level of parking: The.second level of parking is reached by
a ramp directly from Bayview Place: This reduces the circulation
> within the main parking lot and distributes the ingress and egress.
among different points. �
It is presently contemplated to have the main lobby two stories high
adjacent to the exterior.
�� The building is located ori the site so as to provide maximum views
of the bay while at the same time being oriented so that the building
to the west is seen only in a fore-shortened perspective.

ENVIRQNMENTAL SETTING

�
? CLIMATE AND AIR QUALITY
The project area experiences a marine type climate similar to
� that at the San Francisco International Airport.
The winters are�relatively mild and wet; the summers, dry and
cool. Because of the marine influence, the daily and annual
, temperature range is relatively narrow. Temperatures in the project
J
area range from an average high of 69°F (degrees Fahrenheit) to an
average low of 48°F for a mean temperature of 58�F. Prevailing �aind
� is from west to northwest, light in the morning but increasinq in
�strength in the afternoon. The average wind velocity throughout
�
the year is eight miles per hour, although in the summer months
� � the average increases to twelve or thirteen miles per hour. Severe
storms and gale winds occur only occasionally; however, unusual wind
v�locities of fifty miles per hour have been experienced in sumi:�er,
� as well as winter. The afternoon winds, together with a typical
morning overcast, are responsible for the generally cool summers.
Winter rains (December through rZarch) account for about three-fourt-hs
> of the average annual rainfall of about eighteen inches.
The air quality in the vicinity of the project site is generally
good. The site falls within an�area where there�are approximately
� 15-20 days per year with high oxidant levels (.10 ppm) (See Figure 13
Air Pollution Contours). The major elements of air pollution are
most likely from automobile and aircraft sour_ces.

GEOLOGICAL AND SOIL CHARACTERISTICS
�
�
�
The project site is situated within the northern part of
the Coast Range Province which extends from San Francisco for
The Coast Range landscape is characterized throughout its length
by a series of rugged, subparallel, northwest-trending mountain
about 200 miles to the Transverse Ranges in Southern California.
ranges and intervening valleys. This regional landscape is
reflected in the study area by the flat Baylands Valley which
trends northwest.parallel to the nearby Burlingame Hills located
west of the site.
�
The geologic structure of the area is complex and known only
�
on a regional basis. The structure has been molded by orogenic
� events and is characterized by extensive folding, fracturing, and
fault'ing of variable intehsity. Regionally, the folds�and faults
trend northwesterly. This trend has been responsible for the
� erosional,development of the region's pronounced northwest trending
ridge-valley s.ystem.�`The�oldest bedrock formations of the study
area (Jurassic-Cretaceous) have been subjected to repeated episodes
� of deformation and are intensely and complexly folded, faulted and
sheared. By comparison, the youngest formations (Late Quaternary)
have been only mildly flexed. Under the Bay and around the Bay
� perimeter are very young (less than 10,000 years) unconsolidated
bay sediments which are flat-lying. These deposits overlie older,
more compact sediments, locally several hundred feet thick, which
�
1
J
�
in turn overlie old basement rock.
� The study site is considered to be in a region of high seismic
activity, as are all the sites in the San Francisco Bay area. It
is possible that an.earthquake having a magnitude equal to or
� greater than those which are known to have occurred in the past
may occur during the economic life of the proposed structure.
Relative to other Bay Area localities, the damage intensity in the
' Baylands area of Burlingame was high (IX on the Ross-Forel Scale,
Carnegie Institute, 1908) during the 1906 San Francisco.earthquake.
�
The 1973 Uniform Building Code requires a seismic design factor
as set forth under Section 2314. No specific figures are given for
�
soil slopes and fills. .
� In recognizing the possible effects of earthquake activity_on the
planned building; a reasonable :balance should be made between the
probability of the occurence of an earthguake that produces a
� specific acceleration and the cost associated with resisting that
specific acceleration.
� A number of soils investigations have been performed in the
vicinity of the project within the last year by LeRoy Crandall and
Associates, Consulting Geotechnical Engineers. While there is
� local variation of the subsurface conditions, at the three sites
which fall within a mile of the site along Airport•Boulevard and
�
� _
�
which bracket the site, certain �imilarities of geology are
apparent and a general understanding of subsurface conditions
J can be gleaned. �
Soil Conditions
�
The site is a part of a reclamation project that was developed
by filling a low tideland area. The filling reportedly �aas done
in the late 1960's. Fill soils, which range throughout the Anza
�
� lands in depth from three to eight feet, overlie the project site.
The fill consists of silts.and clays and contains some debris.
This site is one of the older and thus�more stable fills in the
,
,
� , area. .- --- --- � _- - - - _ _
�
The natural soils immediately beneath the fill consist of
� highly compressible soft clays (bay mud). These soils rancje from
four to twelve feet in thickness within the area but borings on
adjacent properties indicate a probable thickness of about four
� to five feet.

NOISE
1
�
The General Land Use Recommendations of the Interim Airport
Land Use Plan adopted 2/28/73 by the Regional Planning Committee
states that a commercial development of this type in a 65 CNEL
area is "satisfactory, with little noise impact.and requiring no.
special insulation requirements for new construction".
% The other noise factor in the vicinity is the Bayshore Freeway.
However, the project is adequately buffered by 600 feet of open
space and landscaping. Noise effects are minimal.
,
;
�
�
�
,
�
Within the project, noise will be maintained at a minimal level
� due.to mandatory speed limits of 10 m.p.h. and the relatively short
distance which can be driven. There will be a minimum of through
traffic; the majority of the automobiles will be stopping within
the facility. The project will not draw large, excessively noisy
trucks.
�
�
�
�
BIOLOGICAL
� '
Tne site presently consists of a cleared and compacted vacant
lat. No vertibrates or evidence of their habitations were observed
� on.the site, although rodents may be presumed to occasionally pass
th�ough the site and a variety of bird life to fly over it. Some
ha�rdy native plants, particularly lambsquarter, are found in scattered
� portions of the sa.te. The greatest amount of plant materials near
tl�e area occurs in the landscaped areas across the street from tne
site at the Purdy Building.
� � Since the site does not_b�order the Bay or the Lagoon, its appeal �
, �s a habitat is limited for marsh dwelling species which constitute
the pzedominant ecosystem of the Anza Park area.� None of the
J animals on the Department of the Interior's "Rare" or "Endangered"
species list are likely ,to make use of or be encountered upon the �
. site. . .

�
�
�
�
TRAFFIC
�
The traffic generation (volume of traffic to and from a building)
is a function of the usage of the building. The present traffic
situation is one where little traffic is observed at non-peak hours.
�
Airport Boulevard basically serves only the existing office buildings
with hardly any through traffic. Through traffic is normally
confined to the Bayshore Freeway.
�
During morning and evening peak hours there is considerably more
traffic visible. This traffic, however�did have free flow capability
; in that Airport Boulevard has been designed to accomodate up to two
million square feet of office space and one million square feet of.
�
hotel and commercial space. The critical strictures on access, as
� investigated in the Drachman and Blayney reports are the intersection
capacities at 101 and Bayshore and at Airport and Cayote Point Road.
These reports indicate levels of usage at these points still have
� reserve capacity for future development.
�
�
�
> -
�
UTILITIES
�
The master plan for the street and utility systems for the
Froject was basically developed in 1967. Although it was not
known what the ultimate building layout would be when the utility
�
master plan was designed in 1967, that initial master utility plan
did envision a heavy use of utilities comparable to what will be
� '
�
required for the Master Plan, which was eventually proposed in 1974.
Consequently, the utility systems which have been installed, along
w�.th those remaining to be installed, will be�adequate to serve the
proposed project and will meet the latest requirements of the various
. Utility Corripanies and City of Burlingame Departments involved: The
� bulk of the utility systems required to serve the Project are
currently in place and all of these existing uti7.ity systems were
,
J
designed, constructed, and inspected under the jurisdiction of the
City of Burlingame, P.G. & E. and P. T. & T., are of the latest
�
modern type and quality, and all are in excellent working coridition.
Although the bulk of the utility systems lie within Airport Blvd.,
the.construction of which was completed in 1970, the 1967 street
� master plan called for the connection of Anza Pacific Blvd. east
and west across what has since become �he Anza Lagoon (Outer Lagoori)
and the current Utility Master Plan has thus been ammended to fit �
� the Lagoon land use configuration. The fact that 11.2 acres of land
�
�
�
is now being uti,lized for the Anza Lagoon is a plus factor on the
� utility systems as that area will not now be used for structures
that were originally to contribute loads to the various utility
systems.
,
J Water Distribution
Generally, the water distribution system is designed to deliver
� a minimum of 4000 gallons per minute with a residual pressure of at
least 20 pounds per square inch (psi) at any given point within the
Development, which is the City of Burlingame Fire Department and
� Insurance Underwriters fire fighting requirements for the Project.
The water fire flow requirements far exceed the daily use.of the
� water supply by the Project building occupants and is thus the
� controlling factor in the overall design of the system.
The existing water system is equipped with Burlingame standard
Greenberg '76' fire hydrants which are approximatel.y 280 feet
� apart and within the street right-of-ways. The proposed project.
will be equipped with an automatic sprinkler system.. The area is
also served by an underground fire alarm system with Fire Alarm
�
' boxes and building connections per Burlingame Fire Department
requirements.
� Water for.the Burlingame City water system is obtained.from.the
City of San Francisco 60" diameter mains which pass through the
City of Burlingame approximately one mile south of the project. The
7
� �
,
�
Burlingame water supply is pretreated by the City of San Francisco
� and is of excellent quality.
Sanitary Sewer System
�. Generally, the area's sanitary sewer system consists of epoxy
lined asbestos cement gravity mains which flow to a sanitary sewer
lift station located within Airport Blvd. From the lift station
� the sewage is pumped via an 8" diameter, 3600 feet long force main
directly to the Burlingame Sewage Treatment Plant.
>
The existing lift station consists of two 7-1/2 horse power
elactrically driven pumps which are automatically controlled and
has a c.apacity af 600 gallons per minute with one pump operating
� .
'� and approximately 750 gallons`per miriute when both pumps are
,
� operating simultaneously. �.
The City of Burlingame Sewage Treatment Plant serves a population
� of approximately 35,000 people and is a modern efficient facility
which has undergone extensive reconstruction during the past several
years.
�
Storm Drainage System ..
At the time the existing storm drain pipes for the Development
j were sized, the Anza Lagoon did not,exist and it was assumed that
those 11.2 Lagoon acres would contribute runoff. �The.Anza Lagoon is
subject to Bay tidal flucuation through the porous rip/rap dyke at
�
�
�
the Lagoon/Bay connection, and of course, will not now contr'ibute
� rurio�f to the storm drain system. The existing storm drain
underground system is therefore oversized and should be adectuate
�
�
�
i
7 -
�,
J
J
�
to drain this project during the worst storm and against the very
severest high tide and wind conditions. The project is adjacent
to the upper end of a 21" � storm drain which flows south easterly
before terminating in the slough.
Electrical Power, Gas; and Telephone Systems
The electrical Power and Natural Gas systems for the Project
are supplied by the Pacific Gas & Electric Company, whil.e the
Telephone system is provided by the Pacific Telephone & Telegraph
Company. With the excepti:on of the existing three wire, overhead,
Streamline type of electric distribution systems down the center
planter islands of Airpo,rt Blvd. all of the electric power,
telephone, fire alarm, and street lighting conduit systems and
services are underground.

CLIMA'�E AND AIR QUALITY
�
The proposed development would generally have an insignificant
effect on the microclimate of the area. A shadow analysis of the
� proposed building indicates.that shading of other properties
adjacent to the development would be insign.ificant throughout the
year. �
� Air quality will be at its lowest level during peak hour traffic_
{'7 - 9 A.M. and 4:30 - 9 P.Pd.) when employees and restaurant patrons
enter and leave the parking areas. However, the amount of emissions
�
� from.traffic to the project will be negligible due to lo�a maximum
, speed rates of 10 m.p.h. and short.traveling distances.-

�EOLOGIC AND SOIL CHARACTERISTICS
�
�
�
y
�
:�
,
.�
�
On the basis of soil investigations it can be concluded that
�he primary geologic hazards affecting the proposed development
w9.thin the site are associated with the settlement-prone bay mud
subsoils and with severe ground shaking related to an earthquake
generated on the San Andreas Fault. Danger of site inundation
by a tsunami or flooding is considered very low during the
economic lifetime of the project. Danger of flooding has been
adequately mitigated by tne existing perimeter dikes. According
to San Mateo County (1975), in the event of a 20-foot high tsunami
runup at the Golden Gate, a 4-foot high tsunami runup nay be
! expected at Ravenwood Point south of the site and an 8-foot runup
at Sierra Point,�north of the site. It is therefore felt that
the existing perimeter dike will provide the site with protection
from a tsunami with roughly 200 year recurrence intervals. Because
no fault�traces are located within the site, the risk of creep or
ground rupture due to faulting is too low to be calculated. In
the event-of a major earthquake, services and public utilities may
j be disrupted.
The compressible bay mud underlying the site surface fills is
�
shallow.in thickness and is largely consolidated under the existing
J fill loads. The addition of.new fill (as for parking and driveway
ramps) and structural loads could result in additional consolidation
and settlement. The settlement would be differential in amount
'>
�
�
because of the varying characteristics and thicknesses of both
� the fill and the underlying compressible soils. �

NOISE
Tn the short term, for approximately one year, the effect of
the construction ot the development will be noticeable to
� pedestri.ans along the street and practically negligible to
building occupants.
Noise levels above 65 to 70 dBA will interfere with normal
� conv�rsation, and a noise level between 60 and 70 dBA can disrupt
s7,eep. During construction, noise levels up to 98 dBA can be
expected at 50 feet from the source.

The most significant source of noise which may affect neighboring

entera.ng or leaving the site.

J
�
�
Within the project, noise will be maintained at a minimal level
due to mandatory speed limits of 10 m.p.h. and the relatively short
�
dis�ance which can be driven. Also, the project is not the type
that is likely to draw large, excessively noisy trucks.

The proposed plan will require construction over 16% of the
site, but since the site is now barren, the loss of negligible
� animal life and the sparse but common plant life will not constitute
a major negative impact. Due to the present condition of the site,
the proposed planting will provide a major positive visual and
� biological impact.
Extensive tree, shrub and ground cover plantings will provide a
pleasing visual aspect. The plant life will be a compatible element
�
with the adjacent features and will provide necessary relief from
buildings, parking lots and garages. Such plantings, if properly
� �
selected, may also attract bird life to augment the transient fowl
� occasional to the area. It is proposed that 160 of the site area
shall be devoted to landscaping. This shall have a very positive
effect on what is presently a barren, compacted earth parking area
�
which is sporadically maintained.

TRAFFIC
/7
This project wi11 involve changes in automobile traffic
patterns in the area. Entrance and exit ramps and dr-iveways
� as shown on the plans, are proposed for this project.
A total of 190 parking spaces shall be provided. Of this
number 59 will be covered by the building concealed by concrete
� railings from street level view. The balance are screened from
the street by landscaped berms.
� The principal source of trip generation data for this report
.--� was "Trip Ends Generation Research Counts" by the California -
�' Department of Transportation. Based on this data we can conclucie
� that the anticipated 140 permanent employees of the building will
have sufficient on site parking with approximately 90 stalls being
devoted to visitors. Also, based on.the average determination that
� 1�,000 square feet.of building area generate 70�trips per day, one
can determine that there will be some 310 trips per day as a result
of this project. Research data indicates that 24.0% of the average
� weekday traffic is concentrated at peak hours resulting in 74 cars
involved at maximum loading.
This analysis is somewhat complicated by the proposed restaurant
� useage of the top floor. Normal office building traffic flow is
bi-lobar, with one peak period in morning and one in the afternoon.
Si.nce restaurant traffic flow is also bi-lobar but with peaks
�
�
�
offset by about four hours from the office �flow peaks, the net
�. �'e5ult for combined use is to lower the peak flows but to have a
higher median flow. This results in a more efficient usage of
the traffic�facilities.
� It is felt that the traffic generated by this project will have
minimal impact on the existing throughfares in that Airport Boulevard
has been designed for traffic far in excess of what this project can
� generate.

UTTLITTES

Water Distxibution
The overall water distribution system in the area has sufficient
� .
capacity for the proposed project as well as for the planned future
development. The existing water mains which were installed by Anza
Pacific for the overall development of the area have been of benefit
� to the adjacent Burlingame water system by nroviding much needed
additional capacity to the Humboldt/Howard vicinity of the City and
by praviding overall continuity�and capacity to the City system
7
northerly of.the Bayshore Freeway.
? Sanitary Sewe� System
� The existing lift station, which serves the area�has sufficient
capaci.ty ta accomodate this project and 610 of the total future
planned development"of.Anza Airport Park. The.existing gravity`
� mains in the vicinity of the project will take�.the estimated peak
hourly flow tributary to that main, flowing less than full with
ze.ro head.
�
The City of Burlingame Sewage Treatment Plant serves a population
o£ approximately 35,000 people and is a modern efficient facility
� which has undergone extensive reconstruction during the past several
years. Reference is hereby made to "WASTEWATER DISPOSAL SYS'�EM
PROJECT" by Jenks & Adamson, consulting Civil Engineers, which
M
�
�
s��tdy details the Treatment Plant installation. The entire Anza
� Projeet, including this project,.creates.no new unanticipated
burden an the Treatment Plant as sufficient plant capacity has
, been prova.ded to serve the Project area arid use. The sewage load
� im�osed on the Treatment Plant won't effect the Plant in any
meanzngful way, as the quantity will be small compared to the
plarit capacity and the quality of sewage generated by commercial
> type developments causes no special treatment problems. As the
peak flow from the;office buildings occurs during working hours,
and the peak flow fram the restaurant occurs during late evening,
� whereas the peak flow from .the predominately residential area . �
serv�d by the Treatment Plant occurs before and after working
� hours, the�Project sewage should not seriously effect the sewage
� plant �eak flow, but should average out the flow rate. Also
because the sewer mains within the�project vicinity are water.
tight and utilize flexible joint type of pipe, storm water .
� infiltra-kion into the Project sariitary system should be virtually
zera, .
j
• Sto�m Drainage
The site consists of 1.74 acres. By the rational formula for
storzn runoff, and assuming a rainfall iritensity of 3-1/2 inches
� p�r hour for a five minute peak or 2 inches per hour for a sixty
minute period, a design steady maximum flow of 4.75 cubic feet
per second. This indicates that tne site would utilize roughly
�
�
�
�� o� the available storm sewer capacity, based upon The
� Tal}aot Formula.
A� the time the existing storm drain pipes for Anza Airport
Pa�'k were sized, the Anza Lagoon did not exist and it was assumed
�
�that those 11.2 Lagoon acres would contribute runoff to the
drainage system. The existing storm drain underground system is
�therefore oversized and will be adequate for the proposed project
�
as well as for future development during the worst storm and
against the very severest high tide and wind conditions.�
� Electrical Power, Gas, and Telephone Systems
When PG&E and Pacific Telephone were contacted in 1974 relative
i
to the proposed development of Anza Airport Park, they indicated at
�
that time that they could provide the required services for the
enti.re Anza Airport Park development. This new service is to be
tinderground and except for consideration of noise and possible
�
traffic disruption due to construction, no negative impact will
resul.t. �

�
UNAVOID!�BLE ADVERSE IT�9PACTS
.�
�
�
� Tl�e foregoing analysis of the environmental impacts of the
proposed project indicates that the impacts are very slight and
�hat many of them are due to the construction of the project
j rather than the operation of the project. Therefore, the impacts
listed below will be broken down into two categories.
Construction related adverse impacts

Heavy equipment noise
Truck traffic and noise �

Creation of dust •
Destruction,of some'existing plant life

PIITIGATION OF ADVERSE IMPACTS
�
�
� TY�e construction related adverse environmental impacts are for
,
a relatively short period of duration. These may be mitigated by
using dust control measures where possible and by coordinating
� traffic diversions to such times as would not conflict with peak
hour traffic patterns. Since there is no housing in the area and
since the site is fairly isolated, construction noise would not
� be a matter for serious concern.
The proposed project is designed in accordance to the massing
�
u
�
proposed in the Anza Airport Park Master Plan. This Mater Plan
was designed to maximize open space and view with access to the
bay and bayfront. Landscaping berms around the street frontage
will visually reduce the structure's height and screen the
parking area from the street.
Landscaping, as shown on the drawings in another section of
� �this report,�shall result in a substantially im�roved environment.
�
�
The lar�dscaping is intended to soften the impact of the building
as we11 as to�block from view the parking.
� Mi�ic�ating the traffic impact may be accomplished in three basic
ways; Staggered and Flexible 6Vorking Time, transit and car pbols.,
and mi�ed occupancy.
The process where the employer schedules different employees to
start and stop work at various times of the day is known as
�
.
�
.J
; staggered working times. When the employee, with the consent of
the employer, selects his own working times it is known as flexible
working time. Either of these techniques can be very effective in
� �reducing peak period traffic; recently, both have become a popular
means of avoiding traffic congestion.
A1so related to the environmental and energy problems are the
� �
recent return to transit and the implementation of new programs
for setting up car pools. As recent trends have shown an upturn
in transa,t usage throughout the nation, San Mateo County has been
,
.�
studying the feasibility of improving commuter rail and bus
service on the peninsula. The Federal EPA recently proposed a
�
series of rules�intended to restrict private use of the automobile.
a .
One of these requires the establishment of regional car pool systems.
I£ BART were extended from San Francisco to San Francisco Airport,.
� a shuttle service between the airport and the project should be
. implemented. While this extension would not be entirely effective
in serving the working force of the project because the line would
,;, not liave many westbay stations near employee honies, the Southern
Pacific line's peninsula stations are located near residential
areas. A shuttle between the Southern Pacific and the project's
� concentrated employment area would therefore be quite effective in
mitigating automobile traffic and reducing traffic below the
estimates herein.
�
.
y _
�
�
; The mixed occupancy of the building, with restaurant and office
uses, acts to lower peak traffic flows and to lower peak utility
demands. When the offices are most active the restaurant is
� dormant and when the offices begin to close, the restaurants corie
to 1ife. -
Since the runoff from the site becomes contaminated with
�
petroleum products during concentration and overland flo�,�, means
must be instituted to prevent these volatiles from reaching the
waters of the Bay. A pit-type clarifier (grease trap) which
z
� combines sedimentation and skimming action shall be installed
to purify the storm waters before they are discharged from the
�
site into the municipal storm drains ,in the right-of-way.

RELATIO�JSHIP BETWEEN SHORT TERM
ENVIR�J�lP1ElVTAL USES & MAINTElVANCE &
ENH,�NCEI�ENT OF LOPJG TERh1 PRODIlCT�VITY
�
�
�
� The shart-term environmental disruption will involve largely
the construction period.insofar as most elements are concerned.
The exception to this is the long-term visual impact of the project.
� Tn other regards, from a long-term point of view, this project will
be productive of substantial enhancement to this site through the
landscaping and design features of the building.
�
The project would also provide a very pleasing 2nvironment in
which many people could work or visit to �ine while enjoying the
�stretic advantage of a bayfront environment. With this type of
�
commercial development and grocath in tax base, the indirect.result
� may be to hasten the day when Burlingame is fully able to develop
its rather extensive park holdings, including its bayfront park
>
immediately to the west and south of the Anza Airport Park
development.
� The overall long-term res.ult of this building and those to
�o�.low should enhance the enjoyment of the bayfront and provide
opportunities for more of our citizens to visit and enjoy the
� watertront environment that has so long been cut off by mud .flats,
the City Dump, and the high speed Bayshore Freeway. The.final� result
will be one which�will greatly.enrich the City of Burlingame and
� make them one of the ou:tstanding environmentally oriented cities
ot the area.
�
IRREVERSIBLE ENVIRONMENTAL CHAP�GES
�
�
� From a long rangepoint of view, there are no irreversible changes,
as a building such as this could always be removed. However, without
contemplating the removal of such a building, whicn is normally
� expected to remain in place for at least fifty years, the environ-
mental changes such as.development and beautification of the
particular site, the provision of employment opportunities, and a �
� project in which persons can enjoy the bayfront and environment
and views would seem to be positive irreversible environmental
changes .
