o Wind breaks (e.g., trees, fences) shall be installed on the windward side(s) of actively disturbed areas of construction adjacent to sensitive receptors.

Wind breaks should have at maximum 50 percent air porosity. o Vegetative ground cover (e.g., fast-germinating native grass seed) shall be planted in disturbed areas as soon as possible and watered appropriately until vegetation is established.
o The simultaneous occurrence of excavation, grading, and ground- disturbing construction activities in the same area at any one time shall be limited. Activities shall be phased to reduce the amount of disturbed surfaces at any one time.
o Avoid tracking of visible soil material on to public roadways by employing the following measures if necessary: (1) site accesses to a distance of 100 feet from public paved roads shall be treated with a six to 12-inch compacted layer of wood chips, mulch, or gravel and (2) washing truck tires and construction equipment of prior to leaving the site. o Sandbags or other erosion control measures shall be installed to prevent silt runoff to public roadways from sites with a slope greater than one percent.

Specific Plan Requirement 10.3.3-2: Construction and Operations Modeling. If future construction projects do not meet the screening level size identified by the Bay Area Air Quality Management District (BAAQMD) for less than significant construction criteria air pollutant emissions, future construction projects shall estimate construction and operation period emissions using modeling methodologies recommended BAAQMD and approved by the City. Average daily emissions predicted for construction projects shall be estimated and compared against project level thresholds identified in Table 3.3-4 in the EIR. Projects that have emissions exceeding the thresholds shall implement appropriate measures to achieve emissions that are below the thresholds, such as the following:
o Use construction equipment that has zero or low diesel particulate matter exhaust and NOx emissions. Exhaust emission (NOx and PM) control measures include:
 All construction equipment larger than 25 horsepower used at the site for more than two continuous days or 20 hours total shall meet U.S.

level. Measures to avoid and/or reduce significant construction health risk impacts, could include the following:
o Use Tier 4 engines for all off-road equipment greater than 25 horsepower (hp) and operating for more than 20 total hours over the entire duration of construction activities.
o Use diesel trucks with 2010 or later compliant model year engines during construction.
o Use renewable diesel during construction.
o Use low-VOC coatings during construction.
o Implement fugitive dust best management practices and if necessary, enhanced measures recommended by BAAQMD.
o Use portable electrical equipment where commercially available and practicable to complete construction. Construction contractors shall utilize electrical grid power instead of diesel generators when (1) grid power is available at the construction site; (2) when construction of temporary power lines is not necessary in order to provide power to portions of the site distant from existing utility lines; (3) when use of portable extension lines is practicable given construction safety and operational limitations; and (4) when use of electrical grid power does not compromise construction schedules.
o Phase construction appropriate to lower the intensity of emissions at any one location with sensitive receptors.
o Provide enhanced air filtration for sensitive receptors adversely affected by project emissions.

Impact AIR-4: The project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people. (Less than Significant Impact)
Specific Plan Requirement 10.3.3-5: Odor Control Plan. Future projects that would generate odors shall develop an odor control plan that addresses plant design to control odors, operating and maintenance procedures to prevent odors, and an action plan to respond to upset conditions that could cause odors and measures to respond to odor complaints. The odor control plan shall describe the design elements and BMPs built into the facility that include:
o Ventilation of the system using carbon absorption, biofiltration, ammonia scrubbers, or other effective means to treat exhausted air from the enclosed facility;

BIOLOGICAL RESOURCES
Impact BIO-1: The project would not have a substantial effect, either directly or through habitat modifications, on any special status species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the CDFW or USFWS. (Less than Significant Impact) Specific Plan Requirement 10.3.5-1: Special Status Plants. At the time development is proposed, focused special status plant surveys shall be completed by a qualified biologist (defined as a person with a minimum of a four-year degree in wildlife sciences, biology, environmental sciences, or equivalent experience in the biological sciences) for alkali milk-vetch and Congdon’s tarplant in the grasslands and vernally mesic areas (e.g., areas with a moderate supply of moisture) of Moffett Park’s northwestern corner.

These surveys shall be completed prior to ground disturbance and shall be timed to occur during the appropriate blooming season for each species.

Surveys conducted in or around April, June, and September would be sufficient to confirm their presence or absence; the timing and number of surveys shall be adjusted based on environmental conditions that may affect blooming in a particular year. The surveys shall follow protocols outlined in the “California Native Plant Society Botanical Survey Guidelines” and the California Department of Fish and Wildlife’s (CDFW’s) “Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Sensitive Natural Communities.” If the alkali milk-vetch and Congdon’s tarplant are determined absent, no additional measures are required.

If the alkali milk vetch and/or Congdon’s tarplant are present, to the maximum extent practicable, the project shall be designed to avoid populations of special status plants. If the project cannot be redesigned to avoid impacts to the identified species, and these impacts are found to be significant as defined by CEQA, then compensation measures shall include development of an on-site restoration plan for these species. The determination of the significance of impacts shall be based on, but not limited to, criteria such as the nature of the habitat impacts (i.e., temporary versus permanent impacts), extent of the species’ range, relative abundance The applicant is responsible for

of regional populations of the species in its range, and the number of plant populations in Moffett Park. Areas to be preserved on-site as open space are expected to be able to fully accommodate any compensation measures for these species. If compensation measures cannot be fully accommodated on- site, then off-site compensatory mitigation (in the immediate vicinity of the identified populations(s), where feasible) would need to be considered. At a minimum, the restoration plan shall contain the following elements:

o Location of restoration areas,
o Propagation and planting techniques to be employed for the restoration effort,
o Timetable for implementation,
o Monitoring plan and performance criteria;
o Adaptive management techniques, and
o A site maintenance plan.

A report would be prepared summarizing the results of the surveys and submitted to the City, along with the restoration plan (if required). The restoration plan shall be reviewed and approved by the City for approval prior to the start of project construction. The objective of the restoration plan would be to replace the special status plants and habitat lost during project buildout at proportional basis to the impact. This would incorporate both the spatial and relative density of the impacted plant and its habitat. Success of the restoration effort would be based on a five-year monitoring program. significant as defined by CEQA,

Specific Plan Requirement 10.3.5-2: Burrowing Owl Survey.

Preconstruction surveys shall be completed by a qualified biologist in areas where burrowing owl habitat occurs such as ruderal lots (not including impervious surfaces). Each preconstruction survey shall consist of two surveys: an initial survey no more than 14 days in advance of the on-set of ground-disturbing activity and a follow-up survey occurring within 24 hours prior to the start of construction. These surveys shall be conducted in accordance with the methods described in the Staff Report on Burrowing Owl Mitigation or the most recent California Department of Fish and Wildlife (CDFW) guidelines at the time development is proposed. The surveys shall cover all areas of suitable burrowing owl habitat within the construction zones.

o If preconstruction surveys are undertaken during the non-breeding season (September 1 through January 31), any burrows occupied by resident owls in areas planned for construction shall be protected by a construction-free buffer with a radius of 150 to 250 feet around each active burrow, with the required buffer distance to be determined in each case by a qualified biologist with at least two years of experience surveying for burrowing owls. Passive relocation of resident owls is not recommended by the CDFW where it can be avoided. If passive relocation is unavoidable, resident owls may be passively relocated according to a relocation plan prepared by a qualified biologist.

o If preconstruction surveys are undertaken during the breeding season (February 1 through August 31) and active nest burrows are located within or near construction zones, a construction-free buffer of 250 feet shall be established around all active owl nests. The buffer areas shall be enclosed with temporary fencing, and construction equipment and workers shall not be allowed to enter the enclosed setback areas. Buffers shall remain in place for the duration of the breeding season. Should construction work be halted or paused for more than one week, new preconstruction surveys shall be prepared meeting the same requirements. After the breeding season (i.e., once all young have left the nest), passive relocation of any remaining owls may take place but only under the conditions described below.

If breeding owls are detected, suitable compensation shall be provided.

Compensation could include collaborating with existing protected areas for the burrowing owls along the San Francisco Bay or collaborating and interacting with the Santa Clara Valley Habitat Plan (Habitat Plan) burrowing owl program. Although the City of Sunnyvale is not within the Habitat Plan area, it is within the extended area for preserving habitat to assist with conservation of burrowing owls for the Habitat Plan; the applicant should collaborate with the Santa Clara Valley Habitat Agency to define a suitable and acceptable compensation strategy. This most likely would result in the applicant funding a defined conservation need for the Habitat Plan.

A report shall be submitted to the City summarizing the results of the survey, any buffer zones, and measures implemented to prevent impacts to nesting burrowing owls and their habitat.

Specific Plan Requirement 10.3.5-3: Bumble Bees Survey. At the time development is proposed in the potentially suitable habitat in the natural lands on the northern side of the Lockheed Martin property, four separate surveys shall be completed by a qualified biologist when the ambient temperatures are greater than 60 degrees Fahrenheit, wind speeds are ideally less than eight miles per hour (mph), and skies are clear enough to see your shadow. Bumble bees typically have an active season, or flight period in warmer months. The flight periods of the two different bumble bees which have potential to occur in Moffett Park are: (1) the Crotch bumble bee’s flight period is typically late February through late October, peaking in early April with a second pulse in July; and 2) the western bumble bee’s flight period is typically early April to early November, with workers peaking in early August and males peaking in late September; the queens’ flight period is early February through late November, peaking in late June and late September. The survey period should be from March through September and should aim for a survey in April, July, August, and September at the least; surveys will depend on local temperatures to identify the specific active season for any given area.

The surveys shall be completed between 12:00 PM and 4:00 PM but may be completed earlier if the weather conditions are good. The surveys shall be completed by walking transects spaced up to approximately 100 feet apart within the affected habitat. Transect widths shall be reduced if needed, so there is complete visual coverage of potential nest, overwintering, and forage sites. These bumblebees are typically found in potential nesting, overwintering, and forge habitat within brush piles, in un-mowed or overgrown areas, hollow logs, abandoned rodent burrows, but can also nest above ground in tufts of grass, old bird nests, rock piles, or cavities in dead trees, as well as milkweeds, daisies, lupines, burclovers, phacelias, and salvias. To the degree any of this habitat exists onsite, focused surveys shall occur within suitable habitat. If possible, bumble bee species shall be The applicant is responsible for

determined, the location of potential or known Crotch bumble bees and western bumble bees shall be recorded via a handheld GPS unit, and a representative picture shall be taken. No bumble bees shall be handled to determine species.

If protected bumble bees are observed on the project site, they shall be avoided via buffer zones (the size of which would be determined at the time surveys are prepared). If protected bumble bees are observed on the site or adjacent to the site and they cannot be fully avoided, construction shall occur during a period of time that minimizes the effect of dust on their lifecycles (which would be determined at the time surveys are prepared). If protected bumble bees are observed on the site, compensation may be necessary; any habitat compensation should protect suitable habitat proportional to the impact.

Following completion of the surveys, a report shall be prepared that documents the methods and summarizes the results of the survey which would identify any buffer zones, and measures to prevent impacts to protected bumble bees. The report shall be submitted to the City prior to issuance of grading permits.

Specific Plan Requirement 10.3.5-4: Steelhead. Plans shall contain the following elements:
o All work adjacent to waterways which may support steelhead shall use adequate silt fencing and Stormwater Pollution Prevention Plan (SWPPP) measures to ensure debris (i.e., soil) does not enter the waterway. o All work over waterways (e.g., bridge work) shall use netting to ensure items such as tools and pollutants do not fall into the waterway. o All work in or around waterways shall ensure an appropriate spill kit is onsite to avoid polluting the waterway.

A bat assessment shall be completed by a qualified biologist and submitted to the City for approval, no more than 30 days prior to removal of trees or buildings. If a non-breeding bat colony is found, or if the tree supports suitable roosting habitat that cannot be fully visibly surveyed (such as peeling bark or cavities in trees, especially high up in trees), the individuals shall be humanely evicted via two-step removal as directed by a qualified biologist to ensure no harm or “take” would occur to any bats as a result of demolition activities. Two-step removal shall occur during the volant seasons in fair weather and outside of the maternity season for bats (March 1 to April 15 or September 1 to October 15). Two-step removal consists of one day of disturbance and removing portions of buildings or trees, as directed by a qualified biologist, followed by the removal of that building or tree the following day; the goal is to disturb the bats and render the trees and The applicant is responsible for

Specific Plan Requirement 10.3.5-7: Salt-marsh Harvest Mouse Survey. A habitat survey shall be completed by a qualified biologist 30 days prior to work within 250 feet of the emergent wetland habitat located in the northeastern corner of Moffett Park to confirm current habitats. If pickleweed or salt grass habitats are within the work area, these areas shall be avoided, and a report shall be submitted to the City summarizing the results of the habitat survey which would identify any buffer zones and expected monitoring efforts to prevent impacts to the salt-marsh harvest mouse and their habitat.

A qualified biologist shall monitor work occurring within 50 feet of habitat identified as suitable for the salt-marsh harvest mouse. This monitor shall stop work should a salt-marsh harvest mouse be detected in the work area until the individual moves out of the construction area and into suitable habitat on its own.

o Stationary noise sources shall be located as far from adjacent receptors as possible, and they shall be muffled and enclosed within temporary sheds, incorporate insulation barriers, or include other measures. o Noise and vibration reducing pile-driving techniques shall be implemented during construction and shall be monitored to ensure no damage to nearby structures occurs (i.e., vibrations above PPVs of 0.25 in/sec at nearby structures). These techniques shall include:
 Installing intake and exhaust mufflers on pile-driving equipment.  Vibrating piles into place when feasible, and installing shrouds around the pile-driving hammer where feasible
 Implementing “quiet” pile-driving technology (such as pre-drilling of piles and the use of more than one pile driver to shorten the total pile driving duration), where feasible, in consideration of geotechnical and structural requirements and conditions
 Using cushion blocks to dampen impact noise, if feasible based on soil conditions
 At least 48 hours prior to pile-driving activities, notifying building owners and occupants within 600 feet of the project area of the dates, hours, and expected duration of such activities
o Prohibit unnecessarily idling of internal combustion engines. o Construction staging areas shall be established at locations that create the greatest distance between the construction-related noise sources and noise- sensitive receptors nearest the project site during all project construction.

Material stockpiles, as well as maintenance/equipment staging and parking areas, shall be located as far as feasible from residential receptors. o Control noise from construction workers’ radios to a point where they are not audible at existing residences bordering the project site. o Where feasible, temporary power service from local utility companies shall be used instead of portable generators.
o Locate cranes as far from adjoining noise-sensitive receptors as possible. o During final grading, substitute graders for bulldozers, where feasible.

o During interior construction, the exterior windows facing noise-sensitive receptors should be closed.
o During interior construction, locate noise-generating equipment within the building to break the line-of-sight to the adjoining receptors. o The contractor shall prepare a detailed construction schedule for major noise-generating construction activities (including pile driving, removal of existing structures; site grading and excavation; installation of utilities; construction of building foundations, cores, and shells; paving; and landscaping). The construction plan shall identify a procedure for coordination with adjacent residential land uses so that construction activities can be scheduled to minimize noise disturbance. o Designate a “disturbance coordinator” who would be responsible for responding to any complaints about construction noise. The disturbance coordinator will determine the cause of the noise complaint (e.g., bad muffler, etc.) and will require that reasonable measures be implemented to correct the problem. Conspicuously post a telephone number for the disturbance coordinator at the construction site and include in it the notice sent to neighbors regarding the construction schedule.

Specific Plan Requirement 10.3.4-2: Operational Noise. Prior to the issuance of building permits, a qualified acoustical consultant shall be retained to review mechanical equipment systems during final design of future projects. The consultant shall review selected equipment and determine specific noise reduction measures necessary to reduce noise to comply with the City’s noise level requirements (including SMC Section

19.42.030 requires that operational noise not exceed 75 dBA along the property line, and that the noise levels not exceed 60 dBA during daytime hours or 50 dBA during nighttime hours at any point on adjacent residential properties). Noise reduction measures could include, but are not limited to, selection of equipment that emits low noise levels and/or installation of noise barriers, such as enclosures and parapet walls, to block the line-of- sight between the noise source and the nearest receptors. Additionally, enclosures and interior wall treatments shall be considered to reduce noise exposure within the on-site units. Alternate measures may include locating equipment in less noise-sensitive areas, where feasible. The specific equipment shall be included on the approved building permit plan set.
