WHEREAS, the City Council held a public hearing on this Initial Study and requested
Mitigated Negative Declaration and Mitigation Montioring Program on September 16, 1997, and
has examined pertinent maps, drawings and documents; and
WHEREAS, the City Council made the following findings:
2
The project does not have the potential to degrade the quality of the environment,
substantially reduce the habitat of fish or wildlife species, cause a fish or wildlife population
drop below sustaining levels, threaten to eliminate a plant or animal community, reduce the
number or restrict the range of a rare or endangered plant or animal or eliminate important
examples of California history because the site is currently covered with a combination of
pavement, gravel, open ground sparsely covered by predominantly non - native plant species
and a remaining warehouse building. There is no identified area which is habitat for rare
or endangered species.
The project does not have the potential to achieve short-term to the disadvantage of long-
term environmental goals because the project will promote the long -term economic
development of the site, and is consistent with the long -term goals of the General Plan to
provide business uses and public shoreline access at the site.
The project does not involve impacts which are individually limited but cumulatively
considerable because the described project constitutes all intended changes to the project
area, is not related to any other project or policy change, and will incorporate both project -
specific mitigation measures and participate in area -wide mitigation measures.
The project does not have any environmental effects which will cause substantial adverse
effects on human beings, either directly or indirectly because the construction of the
proposed office/ research and development complex will enhance the existing office park
uses at Marina Village and other business park and industrial use in the immediate vicinity
of the subject site and provide public access shoreline enhancements.
5. The applicant has agreed to incorporate all the mitigation measures set forth in the Mitigated
Negative Declaration into the project. These mitigations would either avoid adverse impacts
or lessen the potentially significant environmental impacts to less than significant levels.
There is no substantial evidence that the project as revised may have a significant effect on
the environment.
WHEREAS, on the basis of the whole record before the City Council, including the
Mitigated Negative Declaration and all comments received upon it, there is no substantial evidence
that the project will have a significant effect on the environment, and the City Council finds that the
Mitigated Negative Declaration reflects its independent judgement and analysis;
THEREFORE BE IT RESOLVED that the City Council adopts Mitigated Negative
Declaration (IS- 97 -02) with findings (Attachment "A ") and the attached mitigation monitoring
program (Attachment "B ").
NOTICE: Pursuant to Public Resources Code Section 21167, a judicial challenge to the City
Council's action on the Mitigated Negative Declaration must be brought within thirty (30) days after
the filing of a Notice of Determination.

ATTACHMENT A
FINDINGS REGARDING SIGNIFICANT IMPACTS
THAT CAN BE MITIGATED TO A LEVEL OF INSIGNIFICANCE
The following sets forth all significant effects of the Project, all of which can be reduced to a level
of insignificance, and with respect to each effect, makes one or more of the findings set forth in
the Introduction above, states facts in support of such findings.
1 Affordable Housing
1.2.1 Significant Effect. The failure of the Project proponent to incorporate an appropriate
share of affordable housing (either on- or off - site), or make payment of the required in -lieu
fees established by the City of Alameda would result in a potentially significant impact on
the supply of affordable housing in Alameda.
Findings. The City Council hereby makes findings (1). (Finding 1: Changes or alterations
have been required in, or incorporated into the Project which avoid or substantially lessen
the significant environmental effect as identified in the Mitigated Negative
Declaration/Initial Study, because the measures will provide funds to construct the needed
affordable housing units).
Facts in Support of Findings. The following facts or mitigation measures indicate the
identified impact will be reduced to a level of insignificance.
(1) The Project proponent shall be required to pay an in -lieu Affordable Housing
Impact Fee to the City of Alameda, according to the adopted City's Affordable
Housing Fee schedule, or provide affordable housing (it is assumed that the Project
applicants will choose to pay the Housing Fee). The fee is required by the City to
be expended on programs for affordable housing (for very low- and low- income
households), which will reduce the potential impact to a level of insignificance.
(2) Payment of In -Lieu Housing Impact Fee, with payments required according to the
current Fee Schedule, will be made by the Applicant at the time prescribed by the
Affordable Housing Program for individual buildings, to be verified by the Central
Permits Office.
1.2 Differential Settlement
1.2.1 Significant Effect. Due to the presence of up to 30 feet of soft, highly compressible Bay
Mud underlying the surface fill material, large total and differential settlements may occur
at the Project site due to increased loads from new fill and buildings. Settlement may vary
considerably across the site, which could result in damage to buildings and paved areas
which is a potentially significant impact.
Findings. The City Council hereby makes findings (1). (Finding 1: Changes or alterations
have been required in, or incorporated into the Project which avoid or substantially lessen
the significant environmental effect as identified in the Mitigated Negative
Declaration/Initial Study, because the measures will ensure that the building foundation
remain stable and will minimize settlement).
Facts in Support of Findings. The following facts or mitigation measures indicate the
identified impact will be reduced to a level of insignificance.
(1) To minimize these effects, finished site grading plans and structural systems of the
planned buildings shall be designed to minimize abrupt grade changes and irregular
concentration of building loads. Site grades shall remain as close to existing
grades as possible to minimize post - construction settlement. Building foundations
shall be anchored to the hard alluvial soils underlying the Bay Mud by concrete
friction piles. A final geotechnical investigation shall be performed when structural
loads become available to determine the feasibility of reducing pile length by
surcharging building pads. Approach slabs at building entrances shall be
constructed to accommodate differential settlement. All construction shall be
performed in accordance with the current Uniform Building Code and with
recommendations contained in the preliminary and final geotechnical
investigations. Implementation of this mitigation measure would reduce the impact
to a less than significant level.
(2) It will be the responsibility of the Applicant to submit the Final Geotechnical Study
to the City Engineer and the Public Works Department for approval, complete
with submission of grading and structural plans for review of compliance with
approved Final Geotechnical Report.
(3)
Staff of the Public Works Department shall inspect work for each building phase to
determine compliance with approved plans.
1.3 Lateral Displacement
1.3.1 Significant Effect. Strong groundshaking associated with an earthquake could laterally
displace slopes adjacent to Alaska Basin and the Oakland Estuary.
Findings. The City Council hereby makes findings (1). (Finding 1: Changes or alterations
have been required in, or incorporated into the Project which avoid or substantially lessen
the significant environmental effect as identified in the Mitigated Negative
Declaration/Initial Study because the measures will cause buildings to locate in the area
which minimize lateral displacement).
Facts in Support of Findings. The following facts or mitigation measures indicate the
identified impact will be reduced to a level of insignificance.
(1) To avoid damage to Project buildings, they shall be set back at least 30 feet from
the top of slopes. In addition, a final detailed geotechnical investigation shall be
performed following completion of site grading and development plans.
2
Implementation of this mitigation measure would reduce the impact to a less than
significant level.
(2) It will be the responsibility of the Applicant to submit the Final Geotechnical Study
to the City Engineer and the Public Works Department for approval, complete
with submission of grading and structural plans for review of compliance with
approved Final Geotechnical Report.
(3) Staff of the Public Works Department shall inspect work for each building phase to
determine compliance with approved plans.
1.4 Pier Instability
1.4.1 Significant Effect. Heavy vehicular traffic, soil loading associated with landscaping, and
strong groundshaking associated with an earthquake could undermine the structural
stability of the heavy timber pier section of the proposed Project site, potentially resulting
in collapse of all or a portion of the timber section. This could be a significant impact.
However, as currently proposed, the Project would not permit vehicular traffic on the
wooden pier.
Findings. The City Council hereby makes findings (1). (Finding 1: Changes or alterations
have been - required in, or incorporated into the Project which avoid or substantially lessen
the significant environmental effect as identified in the Mitigated Negative
Declaration/Initial Study because the measures will either increase structural load on the
piers or provide for their replacement).
Facts in Support of Findings. The following facts or mitigation measures indicate the
identified impact will be reduced to a level of insignificance.
(1) The current proposal is that the wooden pier would be restricted to pedestrian use.
If at any time in the future the.Project is changed to permit any other use, such as
vehicular traffic or other loading of the heavy timber pier section, the following
mitigation measure shall be implemented: Unsound wooden piers shall be
replaced, and 3 to 5 rows of piling closest to the mooring edge shall be laterally
braced by heavy horizontal timbers at 20 -foot intervals between the pier deck and
the shore mud line. In addition, lateral cross - bracing shall be installed on at least 2
rows of piling parallel to the mooring edge of the pier. This measure would reduce
the potential impact to an insignificant level.
(2) It will be the responsibility of the Applicant to submit the Final Geotechnical Study
to the City Engineer and the Public Works Department for approval, complete
with submission of grading and structural plans for review of compliance with
approved Final Geotechnical Report.
(3)
Staff of the Public Works Department shall inspect work for each building phase to
determine compliance with approved plans.
1.5 Construction Emissions
1.5.1 Significant Effect. The construction- related air quality impact of the proposed Project
would be due to dust generated by equipment and vehicles at the site. Fugitive dust is
emitted by the action of equipment and vehicles and as a result of wind erosion over
exposed earth surfaces. Clearing, grading and earthmoving activities comprise the major
source of construction dust emissions; but, traffic and general disturbance of the soil also
generate significant dust emissions.
The effects of construction activities would include increased settling of dust on horizontal
surfaces in the vicinity of the Project site and locally elevated levels of PM10 downwind of
construction activity. (The prevailing downwind direction from the Project site is east -
southeast.) Depending on the weather, soil conditions, amount of activity taking place
and the nature of dust control efforts these impacts could extend downwind from the
Project site, thereby affecting adjacent businesses by increasing soiling and requiring more
frequent cleaning and /or maintenance activities. These impacts would occur for a period
of approximately 24 months. Construction particulate impacts are considered potentially
significant.
Findings. The City Council hereby makes findings (1). (Finding 1: Changes or alterations
have been required in, or incorporated into the Project which avoid or substantially lessen
the significant environmental effect as identified in the Mitigated Negative
Declarationflnitial Study, because the measure will prevent significant amounts of PM 10
(particles) from being released into the air).
Facts in Support of Findings. The following facts or mitigation measures indicate the
identified impact will be reduced to a level of insignificance.
(1) Construction contracts shall require contractors to prepare and implement a
construction dust mitigation plan for those periods of time when the moisture
content of the soil is so low as to cause the possibility of dust movement off the
site. An appropriate dust mitigation plan shall, at a minimum, include the
following:
(1) Provision of equipment and staffing for watering of all exposed or
disturbed soil surfaces at least twice daily. An appropriate non -toxic dust
palliative or suppressant, added to water before application, shall be
utilized.
(2) Watering or covering of stockpiles of debris, soil, sand or other materials
that can be blown by the wind.
(3)
Regular sweeping of construction area and adjacent streets of all mud and
debris, since this material can be pulverized and later re- suspended by
vehicle traffic.
4
(4) Enforcement of a speed limit of 15 miles per hour for all construction
vehicles when off pavement. This speed restriction shall be incorporated
into the construction contract and enforced by the prime contractor.
Additional enforcement would be provided during visits by the project
inspector.
(5)
All materials transported by truck will be covered or wetted down.
(6) All inactive portions of the site will be watered with an appropriate dust
suppressant, covered or seeded.
(7)
When the above dust control measures are unable to avoid visible dust
plumes during periods of high winds (the wind speed at which this will
occur will vary depending on moisture conditions on the site), all
earthmoving or other dust - producing activities shall be suspended.
The use of watering alone for dust control is estimated to reduce dust emissions by
about 50 percent. The combined effect of the above measures, including the use of
a dust suppressant, would have a control efficiency of 70 to 80 percent, which
would be expected to reduce construction- related impacts to a less -than-
significant level.
(2) It will be the responsibility of the Applicant to submit a copy of the construction
contract to the City Engineer and the Public Works Department, which shall
include the above dust mitigation measures.
(3) Staff of the Public Works Department shall inspect work for each building phase to
determine compliance with approved plans by the Applicant and Contractor.
1.6 Traffic
1.6.1 Significant Effect. The proposed project would have impacts on local streets, and would
affect the level of service at the following intersections in the immediate vicinity of the
project: Atlantic Avenue and Challenger Drive, Marina Village Parkway and Challenger
Drive, Sherman Street at Buena Vista Avenue, and possibly at Triumph Drive and Atlantic
Avenue. Project - generated traffic, in combination with cumulative traffic (i.e., traffic from
existing and other concurrent development projects) would affect other local intersections
including: Santa Clara at Sherman, Buena Vista at Entrance Road, and Webster Street at
Atlantic Avenue. Finally project traffic could affect regional roadways including: the I-
880 on ramps at Jackson Street, the 7th and Harrison Streets intersection and the 5th
Street and Broadway intersection. These impacts are potentially significant.
Findings. The City Council hereby makes findings (1) and (2). (Finding 1: Changes or
alterations have been required in, or incorporated into the project which avoid or
substantially lessen the significant environmental effect as identified in the Mitigated
Negative Declaration/Initial Study). (Finding 2: Such changes or alterations are within
5
the responsibility and jurisdiction of another public agency and not the agency making the
finding. Such changes have been adopted by such other agency or can and should be
adopted by such other agency).
Finding of Equivalent Mitigation Measure
The City Council finds, based upon the entire record before it, that the mitigation measure
presented below in 1.6 (3)(b) is equivalent in scope and effectiveness to the mitigation
measure identified and discussed in the Initial Study because the substitute measure will
provide resources which will, with the contributions from other impacting projects, ensure
that the I -880 corridor - Broadway /Jackson interchange will operate at acceptable levels
of service.
Facts in Support of Findings. The following facts or mitigation measures indicate the
identified impact will be reduced to a level of insignificance by insuring that the
interspection and road signals operate at Level of Service "D" or better or otherwise
performs at an acceptable level.
(1) Traffic Improvement Contributions in Vicinity of Project Site The City of
Alameda has planned traffic improvements at several locations in the project
vicinity, including some of the intersections evaluated in the project Traffic Impact
Study. As a condition of approval for new land use development projects, the City
requires project developers to pay the pro -rata, or fair share costs of traffic
improvements required to mitigate their impacts, based on their relative
contribution'to the deterioration of traffic conditions. Although an individual
project by itself may not cause the LOS of a given intersection to deteriorate
substantially, it may have cumulative impacts that would combine with other
development to cause deterioration over time. (Refer to the Initial Study for an
explanation of Level of Service - LOS) The required mitigations ensure that no
individual project will be burdened with the total costs of providing traffic
mitigations when, for example, a minor, but cumulative impact increases an
intersection delay by less than ten seconds and thereby "tips the scale" and causes a
LOS D to deteriorate to LOS E. The project applicant will be required to
contribute a fair share to the cost of the following improvements within the
immediate vicinity of the project site:
a. Installing a traffic signal at the Marina Village Parkway /Challenger Drive
intersection.
Installing a traffic signal at the Atlantic Avenue /Challenger Drive
intersection. The applicant shall fully fund a separate right turn
improvement on Atlantic Avenue at the intersection of Atlantic /Challenger
to facilitate traffic flow, prior to the occupancy of Building One.
c. Improvements to the intersection of Triumph Drive /Atlantic Avenue, if
required.
6
Phase Three of the improvements to Sherman Street, which includes
widening in the area of the Alameda Belt Line Railroad crossing, and other
improvements including bicycle facilities, Buena Vista to Santa Clara..
e. Signalization/channelization of the main project driveway at Atlantic if
warranted.
The fair share contribution to these improvements will be determined by
monitoring actual traffic conditions, as determined by the City Engineer, pursuant
to the Traffic Monitoring Program outlined below.
(2) Other Local Traffic Improvement Contributions: The applicant shall contribute a
fair share portion towards those traffic improvement projects which are expected
to alleviate congestion or otherwise mitigate the cumulative impacts of the project
on other local streets, as determined by monitoring actual traffic conditions
pursuant to the Traffic Monitoring Program outlined below.
(3)
a. The Atlantic/Webster Intersection.
b. The Buena Vista/ Entrance Intersection. Signalization at the intersection
of Buena Vista and Entrance Road if warranted.
c. Santa Clara/Sherman. If warranted, a fair share contribution to this
improvement, as,determined by monitoring actual traffic conditions.
Regional Cumulative Traffic Improvement Contributions. The applicant will be
required to contribute its fair share to several projects addressing cumulative
effects of traffic growth in west Alameda and the regional highway system as
determined by the City Engineer. At present, the contemplated improvements
which the applicant will be required to contribute its fair share to include:
I -880 Corridor Broadway /Jackson Interchange, as described in the Notes of
Meeting, 1-880 Corridor Broadway Jackson Interchange Improvements, dated July
31, 1997 and a one page plan graphic entitled City of Alameda Route 880 in
Oakland Improve Access to Alameda, prepared by Mark Thomas & Co. Inc. date
stamped received on August 26, 1997, which are marked Exhibit "C" and are on
file in the City of Alameda Planning Department. The applicant's fair share shall
be based on the project's actual average am and pm peak hour traffic generation
through the Interchange, divided by the total estimated am and pm peak hour
traffic growth in the Interchange from 1997 to 2010, multiplied by the projected
cost of the improvements at the time the applicant's contribution is due.
Currently, this is estimated as approximately 2% of $17,000,000, which would be
$340,000 based on trip generation as a standard office use. The actual
contribution will be based on best traffic and cost estimates available at the time of
contribution. Components may includel -980 Southbound Off Ramp at Jackson
Into Tube , Posey Exit on 5th to I -880 Southbound On at Oak Street, Depressed
right turn at 7th Harrison., Widen throats of Tubes, Dual I -880 Northbound On-
ramp at Jackson w /auxiliary lane.
7
The fair share contribution to these improvements will be determined by
monitoring actual traffic conditions, as determined by the City Engineer, pursuant
to the Traffic Monitoring Program outlined below. Direct mitigation of some of
the cumulative impacts is beyond the jurisdiction of the City of Alameda, and are
under the jurisdiction of the California Department of Transportation (Caltrans)
and the City of Oakland.
(4) Other Traffic Mitigations. The applicant shall also make annual contributions for
the BART Shuttle and other transportation systems management (TSM) measures
already in place for the Marina Village development area, which will be needed to
serve the project, as determined by monitoring actual traffic conditions pursuant to
the Traffic Monitoring Program outlined below.
(5)
Project Traffic Impact Mitigation and Monitoring Program. The proposed use is
basically an office use and office trip generation rates have been used to assess
worst case traffic impacts. However, the project applicant's existing trip
generation rates are substantially lower than those normally used for office uses,
more like a Research and Development Use. Similar to other computer firms,
Wind River Systems employees tend to travel to and from work outside of peak
hours and work longer hours. The applicant has requested that the extent of
project mitigation requirements be linked to the actual amount of traffic generated,
especially at peak hours. If the project applicant's existing traffic systems
management (TSM) measures, including flextime rules, continue to prevail, fewer
of the contemplated mitigation measures or lower proportionate contributions may
be necessary than would be the case under typical or standard office use
conditions. Therefore, the extent of mitigation required beyond those specific
measures set forth herein and the applicant's contribution towards mitigating
cumulative impacts (and fair share costs thereof) will be determined on the basis of
monitoring of actual Project traffic.
The fair share of improvements in the project vicinity, shall be calculated on the
percentage share of the project traffic compared to a base year of 1984 for those
intersections listed. Project traffic shall be monitored beginning when the Project
reaches 50 percent of projected maximum occupancy and continue until five years
after completion of the Project. However, monitoring of the intersection of Buena
Vista Avenue and Entrance Road will be continued indefinitely, until the City
Engineer is reasonably satisfied with the operation of the intersection.
The Project applicant shall bear the cost of monitoring Project traffic and the
monitoring shall be accomplished in a manner and on a schedule reasonably
acceptable to the City Engineer. Prior to the issuance of an occupancy permit, the
applicant shall enter into an agreement or provide adequate security for the funding
of such monitoring as well as for funding improvements, if found to be needed, to
the satisfaction of the Planning Director and the City Engineer prior to the issuance
an occupancy permit for buildings one and two. This monitoring program will
incorporate the monitoring requirements for all other traffic mitigation measures
identified in the Mitigated Negative Declaration.
These actions would mitigate the potential traffic impacts of the project to a less
than significant level.
1.7 Lead - Contaminated Soil
1.7 .1 Significant Effect. An extensive area of the Project site is contaminated with lead.
Measured lead concentrations range from 2.5 to 43,000 mg/kg. Soil in an area measuring
approximately 700 feet by 80 feet contains lead exceeding a concentration of 1,000 mg /kg,
which is the EPA's Preliminary Remediation Goal for soil on commercial /industrial sites.
The presence of this lead has the potential to cause adverse health effects on the Project
occupants. Lead exposure has been shown to cause adverse health effects in humans,
including the following: brain and nervous system damage; impaired reproductive
function, including premature birth, low birth rate, and birth defects, including mental
retardation; circulatory system damage, including high blood pressure, hypertension,
stroke, and heart attack; and kidney damage. This is a significant impact on public health
and safety, which can be reduced to a level of insignificance with implementation of the
identified mitigation measure.
Findings. The City Council hereby makes findings (1). (Finding 1: Changes or alterations
have been required in, or incorporated into the Project which avoid or substantially lessen
the significant environmental effect as identified in the Mitigated Negative
Declaration/Initial Study because the process will ensure that the site is remediated before
grading to a level satisfactory to local and State regulatory agencies).
Facts in Support of Findings. The following facts or mitigation measures indicate the
identified impact will be reduced to a level of insignificance.
(1) All soil containing lead in concentrations exceeding 1,000 mg/kg will be excavated
and removed from the Project site by the current owners prior to Wind River
System's acquisition of the Project site and prior to commencement of Project
activities.
(2) A Removal Action Workplan (Woodward- Clyde, Removal Action Workplan for
Lead - Impacted Soil, Wind River Systems Site, Alameda, California, June 13,
1997) for performing the excavation and off -site disposal of lead - impacted soils
was submitted to the Alameda County Department of Environmental Health in
June 1997 by the current property owners. The Department indicated that the
approach would be acceptable, and that they anticipate approving the workplan in
the near future. Removal of lead in accordance with the Removal Action
Workplan would ensure that the impact of lead - contaminated soil would be
insignificant.
9
A\
,
It will be the responsibility ofthe Applicant to present proofto the City (City
Engineer, and/or Public Works Dep that the mitigation has been
performed by the previous land owner in compliance with the Removal Action
Workplan approved by the Alameda County Department of Environmental Health
rior to the issuance of any permits for P jnct activities
1.8 TPH-Contaminated Soil
1.8.1 Significant Effects. TPH motor oil was detected at numerous locations throughout the
Project site, at a maximum concentration of 8,800 nn/kg. A concentration of 3,100
mg/kg of TPH diesel was also detected in one soil sample taken from near the northern
end ofthe site. Although the EPA has not established Preliminary Remediation Goals for
TPH in soil, the Alameda County Department of Environmental Health has established
1,000 mg/kg as the maximum acceptable concentration nfTP}I motor oil in soil at the
Project site, assuming there are no appreciable concentrations ofBTE}( or PNA.
Therefore, this would be a si mificonticopac1 on public health and safety, but which can
be reduced to an insi m �want level with implementation of the mitigation measure
Findings. described below.
The Ci Council hereby makes findings (1). (Finding 1: Changes or alterations
have been required in, or incorporated into the Project which avoid or substantially lessen
the significant environmental into zffectasidcntdOedintbe Mitigated Negative
Declaration/Initial Study because the process will ensure that the site is remediated to a
level satisfactory to local and State regulatory agencies).
Facts in Support of Findings. The following facts or mitigation measures indicate the
identified impact will be reduced to a level of ii ifi .
(1) On-site soil contaminated with TPH motor oil shall be lefi in place and covered
with pavement, concrete slab on grade, or Iandscaping soil, to prevent human
exposure or mi inn. Implementation of this mitigation would reduce this
impact to an insignificant level
(2) A Risk Management and/or Plan addressing the handling
f TPH
contaminated soil shall be developed and approved by the Alameda County
Department of Environmental Health prior to issuance of permits to execute the
plan. The Department has given preliminary indication that the planned approach
would be acceptable, providing there are adequate buffers of clean soil at least 2 to
3 feet above groundwater and adequate encapsulation.
The applicant shall preserlt grading plans that comply with the Risk Management
and/or Remediation Plan approved by Alameda County Department of
Environmental Health.
(4) City Public Works staff shall inspect the grading upon cornpletion to determine
compliance with approved plans.
10
It will be the responsibility of the Applicant, the Alameda County Department of
Environmental Health, the City Engineer, and the City of Alameda Public Works
Department to ensure the effective implementation of the above program.
1.9 Pile Driving.
1.9 .1 Significant Effects. Construction of the proposed Project would require driving piles for
building foundation support. Because the Project would be constructed in phases, the
duration of pile driving activities would be reduced, but would recur each time a new
phase of construction began. Typical pile driving equipment generates about 100 dBA of
noise at 50 feet during each impact. The closest off -site building, which houses some
offices, would be approximately 200 feet from the nearest pile - driving activity. Peak
outdoor noise levels at this distance are predicted to be 89 dBA. With noise attenuation
from typical office building facades of 30 dBA, this would result in an interior Lmax of 59
dBA. This level of sound may cause speech interference and annoyance at the adjacent
land uses. This would be a significant impact unless it is mitigated to a level of
insignificance with implementation of the following mitigation measure.
Findings. The City Council hereby makes findings (1). (Finding 1: Changes or alterations
have been required in, or incorporated into the Project which avoid or substantially lessen
the significant environmental effect as identified in the Mitigated Negative

ATTACHMENT B
WIND RIVER MITIGATED NEGATIVE DECLARATION
MITIGATION MONITORING PROGRAM
I. Impact:
Affordable Housing. The failure of the Project proponent to incorporate an appropriate
share of affordable housing (either on- or off-site), or make payment of the required in-lieu
fees established by the City of Alameda would result in a potentially significant t impact on
the supply of affordable housing in Alameda.
Mitigation Measure:
Payment of In-Lieu Affordable Housing Impact Fee. The Project proponent shall be
required to provide affordable housing, or pay an in-lieu Affordable Housing Impact Fee to
the City of Alameda, according to the adopted City's Affordable Housing Fee schedule. It
is assumed that the Project applicants will choose to pay the Housing Fee. The fee is required
by the City to be expended on programs for affordable housing (for very low- and low-income
households), which will reduce the potential impact to a level of insignificance. The City will
establish a time schedule for payment of the fees at the time it approves the Project.
Responsibility:
Applicant and Central Permits Office
Action:
Payment of In-Lieu Housing Impact fee to be made at the time required by the
Affordable Housing Program, for individual buildings.
II. Impact:
Differential Settlement. Due to the presence of up to 30 feet of soft, highly compressible
Bay Mud underlying the surface fill material, large total and differential settlements may occur
at the Project site due to increased loads from new fill and buildings. Settlement may vary
considerably across the site, which could result in damage to buildings and paved areas. This
is a potentially significant impact.
Mitigation Measure:
Differential Settlement. To minimize these effects, finished site grading plans and structural
systems of the planned buildings shall be designed to minimize abrupt grade changes and
irregular concentration of building loads. Site grades shall remain as close to existing grades
as possible to minimize post-construction settlement. Building foundations shall be anchored
to the hard alluvial soils underlying the Bay Mud by concrete friction piles. A final
geotechnical investigation shall be performed when structural loads become available to
determine the feasibility of reducing pile length by surcharging building pads. Approach slabs
at building entrances shall be constructed to accommodate differential settlement. All
construction shall be performed in accordance with the current Uniform Building Code and
with recommendations contained in the preliminary and final geotechnical investigations.
Implementation of this mitigation measure would reduce the impact to a less than significant
level.
Responsibility:
Applicant, City Engineer & Public Works Department
Action:
Applicant to submit Final Geotechnical Study to City Engineer for approval.
Applicant to submit grading and structural plans for review of compliance with
approved Final Geotechnical Report.
Public Works Staff shall inspect work for each building phase to determine
compliance with approved plans.
III. Impact:
Lateral Displacement. Strong groundshaking associated with an earthquake could laterally
displace slopes adjacent to Alaska Basin and the Oakland Estuary. This would be a
significant impact.
Mitigation Measure:
Lateral Displacement. To avoid damage to Project buildings, they shall be set back at least
30 feet from the top of slopes. In addition, a final detailed geotechnical investigation shall be
performed following completion of site grading and development plans. Implementation of
this mitigation measure would reduce the impact to a less than significant level.
Responsibility:
Applicant, City Engineer & Public Works Department
Action:
Applicant to submit Final Geotechnical Study to City Engineer for approval.
2
2. Applicant to submit grading and structura plans for review of compliance with
approved Final Geotechnical Report.
3. Public Works Staff shall inspect work for each building phase to determine
compliance with approved plans.
IV. Impact:
Pier Instability. Heavy vehicular traffic, soil loading associated with landscaping, and strong
groundshaking associated with an earthquake could undermine the structural stability of the
heavy timber pier section of the proposed Project site, potentially resulting in collapse of all
or a portion of the timber section. This could be a significant impact. However, as currently
proposed, the Project would not permit vehicular traffic on the wooden pier.
Mitigation Measure:
Pier Limitations and Stabilization. The current proposal is that the wooden pier would be
restricted to pedestrian use. If at any time in the future the Project is changed to permit any
other use, such as vehicular traffic or other loading of the heavy timber pier section, the
following mitigation measure shall be implemented: Unsound wooden piers shall be replaced,
and 3 to 5 rows of pilings closest to the mooring edge shall be laterally braced by heavy
horizontal timbers at 20-foot intervals between the pier deck and the shore mud line. In
addition, lateral cross-bracing shall be installed on at least 2 rows of pilings parallel to the
mooring edge of the pier. This measure would reduce the potential impact to an insignificant
level.
Responsibility:
Applicant, City Engineer & Public Works Department
Action:
Applicant to submit Final Geotechnical Study to City Engineer for approval.
2. Applicant to submit grading and structural plans for review of compliance with
approved Final Geotechnical Report.
3. Public Works Staff shall inspect work for each building phase to determine
compliance with approved plans.
V. Impact:
Construction Emissions. The construction-related air quality impact of the proposed
Project would be due to dust generated by equipment and vehicles at the site. Fugitive dust
is emitted by the action of equipment and vehicles and as a result of wind erosion over
exposed earth surfaces. Clearing, grading and earthmoving activities comprise the major
source of construction dust emissions; but, traffic and general disturbance of the soil also
generate significant dust emissions.
The effects of construction activities would include increased settling of dust on horizontal
surfaces in the vicinity of the Project site and locally elevated levels of PM,, downwind of
construction activity. (The prevailing downwind direction from the Project site is east -
southeast.) Depending on the weather, soil conditions, amount of activity taking place and
the nature of dust control efforts these impacts could extend downwind from the Project site,
thereby affecting adjacent businesses by increasing soiling and requiring more frequent
cleaning and/or maintenance activities. These impacts would occur for a period of
approximately 24 months. Construction particulate impacts are considered potentially
significant.
Mitigation Measure:
Construction Emissions. Construction contracts shall require contractors to prepare and
implement a construction dust mitigation plan for those periods of time when the moisture
content of the soil is so low as to cause the possibility of dust movement off the site. An
appropriate dust mitigation plan shall, at a minimum, include the following:
Provision of equipment and staffing for watering of all exposed or disturbed soil
surfaces at least twice daily. An appropriate non -toxic dust palliative or suppressant,
added to water before application, shall be utilized.
Watering or covering of stockpiles of debris, soil, sand or other materials that can be
blown by the wind.
Regular sweeping of construction area and adjacent streets of all mud and debris,
since this material can be pulverized and later re- suspended by vehicle traffic.
Enforcement of a speed limit of 15 miles per hour for all construction vehicles when
off pavement. This speed restriction shall be incorporated into the construction
contract and enforced by the prime contractor. Additional enforcement would be
provided during visits by the Project inspector.
All materials transported by truck will be covered or wetted down.
All inactive portions of the site will be watered with an appropriate dust suppressant,
covered or seeded.
When the above dust control measures are unable to avoid visible dust plumes during
periods of high winds (the wind speed at which this will occur will vary depending on
4
moisture conditions on the site), all earthmoving or other dust - producing activities
shall be suspended.
The use of watering alone for dust control is estimated to reduce dust emissions by
about 50 percent. The combined effect of the above measures, including the use of
a dust suppressant, would have a control efficiency of 70 to 80 percent, which would
be expected to reduce construction- related impacts to a less- than - significant level.
Responsibility:
Applicant, Contractor
Action:
Construction contract shall include the required mitigation measure.
mpact:
Traffic. The proposed project would have impacts on local streets, and would affect the level
of service at the following intersections in the immediate vicinity of the project: Atlantic
Avenue and Challenger Drive, Marina Village Parkway and Challenger Drive, Sherman Street
at Buena Vista Avenue, and possibly at Triumph Drive and Atlantic Avenue. Project -
generated traffic, in combination with cumulative traffic (i.e., traffic from existing and other
concurrent development projects) would affect other local intersections including: Santa Clara
at Sherman, Buena Vista at Entrance Road, and Webster Street at Atlantic Avenue. Finally
project traffic could affect regional roadways including: the I -880 on ramps at Jackson Street,
the 7th and Harrison Streets intersection and the 5th Street and Broadway intersection. These
impacts are potentially significant.
Action:
In order to mitigate potential traffic impacts, the City would require the following
comprehensive program:
Traffic Improvement Contributions in Vicinity of Project Site: The City of Alameda
has planned traffic improvements at several locations in the Project vicinity, including
some of the intersections evaluated in the Project Traffic Impact Study. As a
condition of approval for new land use development projects, the City requires
project developers to pay the pro -rata, or fair share costs of traffic improvements
required to mitigate their impacts, based on their relative contribution to the
deterioration of traffic conditions. Although an individual project by itself may not
cause the LOS of a given intersection to deteriorate substantially, it may have
cumulative impacts that would combine with other development to cause
deterioration over time. (Refer to the Initial Study for an explanation of Level of
5
Service - LOS) The required mitigations ensure that no individual project will be
burdened with the total costs of providing traffic mitigations when, for example, a
minor, but cumulative impact increases an intersection delay by Tess than ten seconds
and thereby "tips the scale" and causes a LOS D to deteriorate to LOS E. The
Project applicant will be required to contribute a fair share to the cost of the following
improvements within the immediate vicinity of the project site:
a. Installing a traffic signal at the Marina Village Parkway /Challenger Drive
intersection.
Installing a traffic signal at the Atlantic Avenue /Challenger Drive intersection.
The applicant shall fund a separate right turn improvement on Atlantic Avenue
at the intersection of Atlantic /Challenger to facilitate traffic flow, prior to the
occupancy of Building One.
c. Improvements to the intersection of Triumph Drive /Atlantic Avenue,
required.
Phase Three of the improvements to Sherman Street, including bicycle
facilities, Buena Vista to Santa Clara.
e. Signalization/channelization of main project driveway at Atlantic if warranted.
The fair share contribution to these improvements will be determined by
monitoring actual traffic conditions, as determined by the City Engineer,
pursuant to the Traffic Monitoring Program outlined below.
Other Local Traffic Improvement Contributions: The applicant shall contribute a fair
share portion towards those traffic improvement projects which are expected to
alleviate congestion or otherwise mitigate the cumulative impacts of the Project on
other local streets, as determined by monitoring actual traffic conditions pursuant to
the Traffic Monitoring Program outlined below.
a. The Atlantic/Webster Intersection.
The Buena Vista/ Entrance Intersection. Signalization at the intersection of
Buena Vista and Entrance Road if warranted.
c. Santa Clara/Sherman If warranted, a fair share contribution to this
improvement, as determined by monitoring actual traffic conditions.
Regional Cumulative Traffic Improvement Contributions. The applicant will be
required to contribute its fair share to several projects addressing cumulative effects
of traffic growth in west Alameda and the regional highway system as determined by
6
the City Engineer. At present, the contemplated improvements which the applicant
will be required to contribute its fair share to include:
1-880 Corridor Broadway/Jackson Interchange, as described in the Notes of Meeting,
1-880 Corridor Broadway/Jackson Interchange Improvements, dated July 31, 1997
and a one page plan graphic entitled City of Alameda Route 880 in Oakland Improve
Access to Alameda, prepared by mark Thomas & Co. Inc. Date stamped received on
August 26, 1997, which are marked Exhibit"C" and are on file in the City of Alameda
Planning Department. The applicant's fair share shall be based on the project's actual
average am and pm peak hour traffic generation through the Interchange, divided by
the total estimated am and pm peak hour traffic growth in the Interchange from 1997
to 2010, multiplied by the projected cost of the improvements at the time the
applicant's contribution is due. Currently, this is estimated as approximately 2% of
$17,000,000, which would be $340,000 based on trip generation as a standard office
use. The actual contribution will be based on best traffic and cost estimates available
at the time of contribution. Components may include 1-880 Southbound Onramp at
Oak Street, Depressed right turn at 7th/ Harrison, Widen throats of Tubes, Dual I-880
Northbound On-ramp at Jackson with auxiliary lane.
The fair share contribution to these improvements will be determined by monitoring
actual traffic conditions, as determined by the City Engineer, pursuant to the Traffic
Monitoring Program outlined below.
4. Other Traffic Mitigations. The applicant shall also make annual contributions for the
BART Shuttle and other transportation systems management (TSM) measures already
in place for the Marina Village development area, which will be needed to serve the
Project, as determined by monitoring actual traffic conditions pursuant to the Traffic
Monitoring Program outlined below.
5. Project Traffic Impact Mitigation and Monitoring Program. The proposed use is
basically an office use and office trip generation rates have been used to assess worst
case traffic impacts. However, the Project applicant's existing trip generation rates
are substantially lower than those normally used for office uses, more like a Research
and Development Use. Similar to other computer firms, staff tend to travel to and
from work outside of peak hours and work longer hours. The applicant has requested
that the extent of Project mitigation requirements depend on the actual amount of
traffic generated, especially at peak hours. If the Project applicant's existing traffic
systems management (TSM) measures, including flextime rules, continue to prevail,
fewer of the contemplated mitigation measures or lower proportionate contributions
may be necessary than would be the case under typical or standard office use
conditions. Therefore, the extent of mitigation required beyond thosc specific
measures set forth herein and the applicant's contribution towards mitigating
cumulative impacts (and fair share costs thereof) will be determined on the basis of
monitoring of actual Project traffic.
7
The fair share of improvements in the project vicinity, shall be calculated on the
percentage share of the project traffic compared to a base year of 1984 for those
intersections listed. Project traffic shall be monitored beginning when the Project
reaches 50 percent of projected maximum occupancy and continue until five years
after completion of the Project. However, monitoring of the intersection of Buena
Vista Avenue and Entrance Road will be continued indefinitely, until the City
Engineer is reasonably satisfied with the operation of the intersection.
The Project applicant shall bear the cost of monitoring Project traffic and the
monitoring shall be accomplished in a manner and on a schedule reasonably acceptable
to the City Engineer. Prior to the issuance of an occupancy permit, the applicant shall
enter into an agreement or provide adequate security for the funding of such
monitoring as well as for funding improvements, if found to be needed, to the
satisfaction of the Planning Director and the City Engineer prior to the issuance an
occupancy permit for buildings one and two. This monitoring program will
incorporate the monitoring requirements for all other traffic mitigation measures
identified in the Mitigated Negative Declaration.
These actions would mitigate the potential traffic impacts of the project to a less than
significant level.
Responsibility:
Applicant, City Engineer, Public Works Department
VII. Impact:
Lead- Contaminated Soil. An extensive area of the Project site is contaminated with lead.
Measured lead concentrations range from 2.5 to 43,000 mg/kg. Soil in an area measuring
approximately 700 feet by 80 feet contains lead exceeding a concentration of 1,000 mg/kg,
which is the EPA's Preliminary Remediation Goal for soil on commerciaUindustrial sites. The
presence of this lead has the potential to cause adverse health effects on the Project
occupants. Lead exposure has been shown to cause adverse health effects in humans,
including the following: brain and nervous system damage; impaired reproductive function,
including premature birth, low birth rate, and birth defects, including mental retardation;
circulatory system damage, including high blood pressure, hypertension, stroke, and heart
attack; and kidney damage. This is a significant impact on public health and safety, which
can be reduced to a level of insignificance with implementation of the following mitigation
measure.
8
Mitigation Measure:
Lead - Contaminated Soil. All soil containing lead in concentrations exceeding 1,000 mg/kg
will be excavated and removed from the Project site by the current owners prior to Wind
River System's acquisition of the Project site and prior to commencement of Project activities.
A Removal Action Workplan (Woodward- Clyde, Removal Action Workplan for Lead -
Impacted Soil, Wind River Systems Site, Alameda, California, June 13, 1997) for performing
the excavation and off -site disposal of lead - impacted soils was submitted to the Alameda
County Department of Environmental Health in June 1997 by the current property owners.
The Department indicated that the approach would be acceptable, and that they anticipate
approving the workplan in the near future: Removal of lead in accordance with the Removal
Action Workplan would ensure that the impact of lead - contaminated soil would be
insignificant.
Responsibility:
Applicant, City Engineer, Public Works Department
Action:
The applicant shall present proof to the City that the mitigation has been performed
by the previous land owner in compliance with the Removal Action Workplan
approved by the Alameda County Department of Environmental Health prior to the
issuance of any permits for Project activities.
II. Impact:
"PH- Contaminated Soil. TPH motor oil was detected at numerous locations throughout
the Project site, at a maximum concentration of 8,800 mg/kg. A concentration of 3,100
mg/kg of TPH diesel was also detected in one soil sample taken from near the northern end
of the site. Although the EPA has not established Preliminary Remediation Goals for TPH
in soil, the Alameda County Department of Environmental Health has established 1,000
mg/kg as the maximum acceptable concentration of TPH motor oil in soil at the Project site,
assuming there are no appreciable concentrations of BTEX or PNA. Therefore, this would
be a significant impact on public health and safety, but which can be reduced to an
insignificant level with implementation of the following mitigation measure.
Mitigation Measure:
TPH- Contaminated Soil. On -site soil contaminated with TPH motor oil shall be left in
place and covered with pavement, concrete slab on grade, or landscaping soil, to prevent
human exposure or migration. Implementation of this mitigation would reduce this impact
to an insignificant level.
9
Responsibility:
Applicant, Alameda County Department of Environmental Health, City Engineer, Public
Works
Action:
A Risk Management and/or Remediation Plan addressing the handling of TPH-
contaminated soil shall be developed and approved by the Alameda County
Department of Environmental Health prior to issuance of permits to execute the plan.
The Department has given preliminary indication that the planned approach would be
acceptable, providing there are adequate buffers of clean soil at least 2 to 3 feet above
groundwater and adequate encapsulation.
2. The applicant shall present grading plans that comply with the Risk Management
and/or Remediation Plan approved by Alameda County Department of Environmental
Health:
City Public Works staff shall inspect the grading upon completion to determine
compliance with approved plans.
IX. Impact:
Pile Driving. Construction of the proposed Project would require driving piles for building
foundation support. Because the Project would be constructed in phases, the duration of pile
driving activities would be reduced, but would recur each time a new phase of construction
began. Typical pile driving equipment generates about 100 dBA of noise at 50 feet during
each impact. The closest off-site building, which houses some offices, would be
approximately 200 feet from the nearest pile-driving activity. Peak outdoor noise levels at
this distance are predicted to be 89 dBA. With noise attenuation from typical office building
facades of 30 dBA, this would result in an interior L 59 dBA. This level of sound may
cause speech interference and annoyance at the adjacent land uses. This would be a
significant impact unless it is mitigated to a level of insignificance with implementation of the
following mitigation measure
Mitigation Measure:
Pile Driving. The hammer driving area shall be surrounded with a pile-driving shield to
deflect and reduce noise. Pile driving activities shall be limited to the hours 8:00 a.m. to 6:00
p.m., Monday through Saturday. Implementation of these mitigation measures would reduce
this impact to insignificance.
10
Responsibility:
Applicant, Contractor, Central Permits Office,
Action:
1 The contractors schedule for pile driving shall conform with the Mitigation.
X. Impact:
Schools. The Project would result in new employee residents of Alameda. Therefore, the
Project would indirectly result in an increased demand for enrollment at local schools. This
impact would be insignificant.
Mitigation Measure:
Schools.. Although this impact is not defined as significant, the applicant shall be required to
pay a per-square-foot impact fee for commercial development to the school district.
Responsibility:
Applicant and Central Permits Office
Actions:
Payment of In-Lieu Impact fee to be made at the time of filing for building permit for
individual buildings.
Impact:
Off-Site Glare. Depending on the design of site lighting standards, including their height and
luminaries, there may be adverse off-site glare to motorists and neighboring residential
properties.
Mitigation Measure:
Shielded Site Lighting. The City of Alameda will require the on-site lighting to meet
standards for downward-directed lighting and shielding to avoid excessive leakage into
adjacent residential areas.
Responsibility:
Applicant, Public Works
11
Action:
The applicant shall submit plans of lighting fixtures, including pole height and number
of lights, for review.
2. The Planning Director shall review the photometric plan submitted by the applicant
and determine whether the plans comply with her requirements. The Planning
Director shall advise the applicant of the decision.
The applicant shall install all lighting in substantial compliance with the Photometric
Plan approved by the Planning Director.
4. Planning Staff shall inspect the work upon completion to verify compliance with the
Photometric Plan. The applicant may be required to modify the on-site lighting and
may be required to install additional shielding in order to comply with the photometric
plan.
