San Francisco Bay Basin Plan
The San Francisco Bay RWQCB regulates water quality in accordance with the Water Quality Control Plan for the San Francisco Bay Basin (Basin Plan). The Basin Plan lists the beneficial uses that the San Francisco Bay RWQCB has identified for local aquifers, streams, marshes, rivers, and the San Francisco Bay, as well as the water quality objectives and criteria that must be met to protect these uses. The San Francisco Bay RWQCB implements the Basin Plan by issuing and enforcing waste discharge requirements, including permits for nonpoint sources such as the urban runoff discharged by a City' s stormwater drainage system. The Basin Plan also describes watershed management programs and water quality attainment strategies.

Municipal Regional Permit Provision C.3
The San Francisco Bay RWQCB re -issued the MRP in May 2022 to regulate stormwater discharges from municipalities and local agencies ( co- permittees) in Alameda, Contra Costa, San Mateo, and Santa Clara Counties, and the cities of Fairfield, Suisun City, and Vallejo. 56 Under Provision C.3 of the MRP, new and redevelopment projects that create or replace 5, 000 square feet or more of impervious surface area are required to implement site design, source control, and Low Impact Development ( LID) -based stormwater treatment controls to treat post -construction stormwater runoff.

LID -based treatment controls are intended to maintain or restore the site' s natural hydrologic functions, maximizing opportunities for infiltration and evapotranspiration, and using stormwater as a resource e. g., rainwater harvesting for non -potable uses). The MRP also requires that stormwater treatment measures are properly installed, operated, and maintained.

In addition to water quality controls, the MRP requires new development and redevelopment projects that create or replace one acre or more of impervious surface to manage development -related increases in peak runoff flow, volume, and duration, where such hydromodification is likely to cause increased erosion, silt pollutant generation, or other impacts to local rivers, streams, and creeks. Projects may be deemed exempt from these requirements if: (1) the post -project impervious surface area is less than, or the same as, the pre -project impervious surface area; ( 2) the project is located in a catchment that drains to a hardened ( e. g., continuously lined with concrete) engineered channel or channels or enclosed pipes, which extend continuously to the Bay, Delta, or flow controlled reservoir, or, in a catchment that drains to channels that are tidally influenced; or (3) the project is located in a catchment or subwatershed that is highly developed (Le., that is 70 percent or more impervious). 57 56 California Regional Water Quality Control Board San Francisco Region.

Municipal Regional Permit Provision C. 12.f
Provision C. 12. f of the MRP requires co- permittee agencies to implement a control program for PCBs that reduces PCB loads by a specified amount during the term ofthe permit, thereby making substantial progress toward achieving the urban runoff PCBs wasteload allocation in the Basin Plan by March 2030. 58 Programs must include focused implementation of PCB control measures, such as source control, treatment control, and pollution prevention strategies. Municipalities throughout the Bay Area are updating their demolition permit processes to incorporate the management of PCBs in demolition building materials to ensure PCBs are not discharged to storm drains during demolition. Buildings constructed between 1950 and 1980 that are proposed for demolition must be screened for the presence of PCBs prior to the issuance of a demolition permit. Single- family residential and wood frame structures are exempt.

Water Resources Protection Ordinance and District Well Ordinance Valley Water operates as the flood control agency for Santa Clara County. Their stewardship also includes creek restoration, pollution prevention efforts, and groundwater recharge. Permits for well construction and destruction work, most exploratory boring for groundwater exploration, and projects within Valley Water property or easements are required under Valley Water' s Water Resources Protection Ordinance and District Well Ordinance.
2021 Groundwater Management Plan
The 2021 Groundwater Management Plan ( GWMP) describes Valley Water' s comprehensive groundwater management framework, including existing and potential actions to achieve basin sustainability goals and ensure continued sustainable groundwater management. The GWMP covers the Santa Clara and Llagas subbasins, which are located entirely in Santa Clara County. Valley Water manages a diverse water supply portfolio, with sources including groundwater, local surface water, imported water, and recycled water. About half ofthe county' s water supply comes from local sources and the other half comes from imported sources. Imported water includes the District' s State Water Project and Central Valley contract supplies and supplies delivered by the San Francisco Public Utilities Commission ( SFPUC) to cities in northern Santa Clara County. Local sources include natural groundwater recharge and surface water supplies. A small portion of the county' s water supply is recycled water.

Local groundwater resources make up the foundation of the county' s water supply, but they need to be augmented by the District' s comprehensive water supply management activities to reliably meet the county' s needs. These include the managed recharge of imported and local surface water and in -lieu groundwater recharge through the provision of treated surface water and raw water, acquisition of supplemental water supplies, and water conservation and recycling. 59 California Regional Water Quality Control Board San Francisco Region.

Local
City of Mountain View 2030 General Plan
The General Plan contains goals and policies to avoid significant impacts due to hydrology and water quality impacts. The following goals and policies are applicable to the proposed project.

Policy Description
Infrastructure and Conservation Element
INC- 8. 2 National Pollutant Discharge Elimination System Permit. Comply with requirements in the Municipal Regional Stormwater National Pollutant Discharge Elimination System Permit MRP).

INC- 8. 4 Runoff pollution prevention. Reduce the amount of stormwater runoff and stormwater pollution entering creeks, water channels and the San Francisco Bay through participation in the Santa Clara Valley Urban Runoff Pollution Prevention Program.

INC- 8. 5 Site -specific stormwater treatment. Require post -construction stormwater treatment controls consistent with MRP requirements for both new development and redevelopment projects.

INC 8. 6 Green streets. Seek opportunities to develop green streets and sustainable streetscapes that minimize stormwater runoff, using techniques such as on -street bio- swales, bio- retention, permeable pavement or other innovative approaches.

INC- 8. 7 Stormwater quality. Improve the water quality of stormwater and reduce flow quantities.

City of Mountain View Code of Ordinances
Chapter 8 ( Buildings) of the City Code includes the currently adopted Green Building Code which details the stormwater management best management practices and regulations required by the City.

Chapter 35 ( Water, Sewage, and other Municipal Services) ofthe City Code outlines the City policies surrounding water infrastructure, including requirements for the discharge of stormwater into the City' s stormwater infrastructure.

4. 10. 1. 2 Existing Conditions
Stormwater Drainage
The municipal storm drain system serving the project site consists of storm drain inlets, conveyance pipes, culverts, channels and retention basins operated by the City of Mountain View Public Works Department. Drainage into the City system generally flows south to north towards San Francisco Bay.

The project site consists of 4. 54 acres ( or approximately 95 percent) of percent impervious surfaces and 0.26 acre ( or approximately five percent) of pervious surfaces. Runoff from the site flows into a 12- inch storm drain line in Terra Bella Avenue and 8- inch storm drain line in Linda Vista Avenue.

Water Quality
The water quality of streams, creeks, ponds, and other surface water bodies can be greatly affected by pollution carried in contaminated surface runoff. Pollutants from unidentified sources, known as Terra Bella Public Storage & ALTA Housing Project 110 Initial Study City of Mountain View November 2022
Resolution No. 18773

nonpoint source pollutants, are washed from streets, construction sites, parking lots, and other exposed surfaces into storm drains. Urban stormwater runoff often contains contaminants such as oil and grease, plant and animal debris ( e. g., leaves, dust, animal feces, etc.), pesticides, litter, and heavy metals. In sufficient concentration, these pollutants have been found to adversely affect the aquatic habitats to which they drain.

While there are no streams, creeks, ponds, or other surface water bodies located within the project site, Stevens Creek is located approximately 0. 22- mile east ofthe project site. Stevens Creek is on the 2006 Clean Water Act Section 303( d) list due to diazinon pollution, total toxicity levels, the water temperature in the creek, and solid waste pollution.

Groundwater
The City of Mountain View is located within the Santa Clara Groundwater Basin ( DWR Basin 2-

9. 02). 60 Hydrologically, the groundwater basin is separated into recharge and confined zones.

Geological conditions in the recharge areas allow precipitation, stream flow, and water diverted into percolation areas to recharge the deeper aquifers. The confined zones include areas of the valley where low permeability clays and silts overlie the major groundwater aquifers which impedes the vertical flow of groundwater into the deeper aquifers. The City of Mountain View, including the project site, lies entirely within the area of the confined zone. 61
As discussed in Section 4. 7. 1. 2, groundwater was encountered under the proj ect site at depths between seven to eight feet bgs.62 Water levels on -site may vary depending on seasonal precipitation, irrigation practices, and other climate conditions.

Flooding
The project site is located within Flood Zone X, which is not a Special Flood Hazard Area as identified by FEMA FIRM.63 Flood Zone X is defined as an area determined to be outside the one percent and

0. 2 percent annual chance floodplains, indicative of a minimal flood hazard.

Seiches and Tsunamis
A seiche is the oscillation of a body of water, typically caused by changes in atmospheric pressure, strong winds, earthquakes, tsunamis, or tidal movements. Seiches occur most frequently in enclosed or semi -enclosed basins such as lakes, bays, or harbors. There are no enclosed or semi -enclosed bodies of water near the project site.

Resolution No. 18773

Impact HYD- 1: The project would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality. ( Less than Significant Impact)
Construction
Implementation of the proposed project would require demolition, excavation, grading, and paving of the project site, which could result in temporary impacts to surface water quality. These construction activities could expose building materials containing PCBs and increase erosion and sedimentation once the disturbed soil is exposed to water and wind. This would increase the potential for soil, sediment, and pollutants to be carried by runoff into local waterways and the San Francisco Bay.

Since the proposed project would disturb more than one acre, it is required to comply with the State of California General Construction Permit and submit a SWPPP and NOI to the SVWRCB. Compliance with the General Construction Permit would ensure that all BMPs related to stormwater pollution prevention for construction projects are implemented. Further, the project is required to comply with the MRP Provision C. 12. f and submit a PCBs Screening Assessment Applicant Package consistent with the City' s Environmental Protection requirements, which require applicants to screen the buildings proposed for demolition to determine whether it is appropriate to conduct additional testing on building materials ( City standard condition of approval COA HAZ- 2. 2). 65 The project would also require dewatering during construction. As discussed in Section 4. 9 Hazards and Hazardous Materials, the project shall implement City standard condition of approval COA HAZ- 2. 1 to implement a soil and groundwater management plan to properly dispose dewatered groundwater. The project would be required to comply with the below City standard conditions of approval, which are consistent with the California General Construction Permit and MRP requirements.

City Standard Conditions of Approval:

COA HYD- 1. 1: The project shall implement the following measures:

State of California Construction General Stormwater Permit: A " Notice of Intent" and " Stormwater Pollution Prevention Plan" shall be prepared for construction projects disturbing one ( 1) acre or more ofland. Proof of coverage under the State General Construction Activity Stormwater Permit shall be attached to the building plans.

Construction Sediment and Erosion Control Plan: The applicant shall submit a written plan acceptable to the City which shows controls to be used at the site to minimize sediment runoff and erosion during storm events. The plan shall include installation of the following items where appropriate: ( a) silt fences around the site perimeter; ( b) gravel bags surrounding catch basins; ( c) filter fabric over catch basins; ( d) covering of exposed stockpiles; ( e) concrete washout areas; ( f) stabilized rock/ gravel driveways at points of egress from the site; and ( g) vegetation, hydroseeding, or other soil stabilization methods for high -erosion areas. The plan shall also include routine street sweeping and storm drain catch basin cleaning.

Terra Bella Public Storage & ALTA Housing Project 113 Initial Study City of Mountain View November 2022
Resolution No. 18773

Construction Best Management Practices: All construction projects shall be conducted in a manner which prevents the release of hazardous materials, hazardous waste, polluted water, and sediments to the storm drain system High -Erosion Storage Areas: High -erosion areas ( areas paved with loose sand/ gravel, areas used for storage of high -sediment -producing materials, such as rock or sand, or areas designated for high traffic or heavy equipment traffic) shall be designed to prevent the run- on of stormwater and runoff of spills by one of the following: ( a) covering the area and either sloping the area inward negative slope) or providing a berm or curb around its perimeter; or ( b) retrofitting the area with a treatment system to intercept and remove sediments from storm drain runoff.

The project, with the implementation of the above City standard conditions of approval COA HYD1. 1, would reduce construction - related water quality impacts to a less than significant level by limiting the release of pollutants into waterways through preparing a NOI and SWPPP, implementing a construction sediment and erosion control plan, construction BMPs and covering high -erosion staging areas. ( Less than Significant Impact)
Post -Construction
Construction of the project would replace more than 10, 000 square feet of impervious surface area.

As a result, the project would be required to comply with the requirements of the MRP. Provision C. 3 requires the project to incorporate site design, source control, and LID -based stormwater treatment controls to reduce the pollutant loads of runoff from the project. The project would reduce and treat surface runoff on -site by using flow -through planters, directing runoff from impervious surfaces to landscaped areas, and installing bioretention areas within the project site. Development of the proposed project, in compliance with existing regulations and best management practices including the MRP and City Code), would reduce water quality impacts.

In addition, the project would be required to include the following measures, based on RWQCB requirements, to reduce stormwater runoff impacts from project implementation.

City Standard Conditions of Approval:

COA HYD- 1. 2 The project shall implement the following measures:

Stormwater Treatment ( C. 3): This project would create or replace more than ten thousand ( 10, 000) square feet of impervious surface; therefore, stormwater runoff shall be directed to approved permanent treatment controls as described in the City' s guidance document entitled, " Stormwater Quality Guidelines for Development Projects." The City' s guidelines also describe the requirement to select Low -Impact Development ( LID) types of stormwater treatment controls; the types of projects that are exempt from this requirement; and the Infeasibility and Special Projects exemptions from the LID requirement.

The " Stormwater Quality Guidelines for Development Projects" document requires applicants to submit a Stormwater Management Plan, including information such as the type, location, and sizing calculations ofthe treatment Terra Bella Public Storage & ALTA Housing Project 114 Initial Study City of Mountain View November 2022
Resolution No. 18773

controls that shall be installed. Include three stamped and signed copies of the Final Stormwater Management Plan with the building plan submittal. The Stormwater Management Plan must include a stamped and signed certification by a qualified Engineer, stating that the Stormwater Management Plan complies with the City' s guidelines and the State NPDES Permit. Stormwater treatment controls required under this condition may be required to enter into a formal recorded Maintenance Agreement with the City.

Landscape Design: Landscape design shall minimize runoff and promote surface filtration. Examples include: ( a) No steep slopes exceeding 10 percent; b) Using mulches in planter areas without ground cover to avoid sedimentation runoff, ( c) Installing plants with low water requirements; and ( d) Installing appropriate plants for the location in accordance with appropriate climate zones. Identify which practices shall be used in the building plan submittal.

Efficient Irrigation: Common areas shall employ efficient irrigation to avoid excess irrigation runoff. Examples include: ( a) Setting irrigation timers to avoid runoff by splitting irrigations into several short cycles; ( b) Employing multi - programmable irrigation controllers; ( c) Employing rain shutoff devices to prevent irrigation after significant precipitation; ( d) Use of drip irrigations for all planter areas which have a shrub density that would cause excessive spray interference of an overhead system; and ( e) Use of flow reducers to mitigate broken heads next to sidewalks, streets and driveways. Identify which practices shall be used in the building plan submittal.

Outdoor Storage Areas ( Including Garbage Enclosures): Outdoor storage areas ( for storage of equipment or materials which could decompose, disintegrate, leak or otherwise contaminate stormwater runoff), including garbage enclosures, shall be designed to prevent the run- on of stormwater and runoff of spills by all of the following: ( a) Paving the area with concrete or other nonpermeable surface; ( b) Covering the area; and ( c) Sloping the area inward (negative slope) or installing a berm or curb around its perimeter. There shall be no storm drains in outdoor storage areas.

With the implementation ofthe City standard conditions of approval, based on RWQCB requirements, the project' s post -construction water quality impacts would be less than significant by treating surface runoff. ( Less than Significant Impact)
Impact HYD- 2: The project would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin. ( Less than Significant Impact)
Groundwater recharge occurs when surface water percolates through the soil to recharge groundwater aquifers. As shown in Table 4. 10- 1, the proposed project would decrease the amount of impervious surface on -site from 95 percent to 81 percent compared to existing conditions. Therefore, implementation of the project would not interfere with groundwater recharge because it would not Terra Bella Public Storage & ALTA Housing Project 115 Initial Study City of Mountain View November 2022
Resolution No. 18773

reduce the amount of surface water that is allowed to percolate on -site. In addition, the project site is not located in a recharge area as identified by the 2021 GWMP. 66 Table 4. 10- 1: Impervious Surface Acreage On -Site

Net Difference ( A- B) 0. 65 14
As discussed in Section 4. 7 Geology and Soils, implementation ofthe project would require temporary groundwater dewatering during construction activities due to the presence of groundwater seven to eight feet bgs and the proposed maximum excavation depth of eight feet. Although construction would require temporary dewatering, the amount of water that would be pumped is not expected to be significant. The project would implement City standard condition of approval COA GEO- 1. 1 to minimize the volume of groundwater removed during project construction and ensure construction dewatering does not substantially decrease groundwater supply. Based on the above discussion, implementation of the proposed project would not substantially deplete groundwater supplies or interfere substantially with groundwater recharge. ( Less than Significant Impact) Impact HYD- 3: The prof ect would not substantially alter the existing drainage pattern ofthe site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would result in substantial erosion or siltation on- or off -site; substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off - site; create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff, or impede or redirect flood flows. ( Less than Significant Impact)
There are no streams or rivers on -site, therefore, the proposed project would not affect the existing drainage pattern of any streams or rivers. As discussed under Impacts HYD- 1 and HYD- 2, the proposed project would comply with Provision C.3 of the MMP requirement to incorporate site design, source control, and LID -based stormwater treatment controls and would decrease the amount of impervious surfaces on -site from 95 to 81 percent, thereby reducing the amount of surface runoff compared to existing conditions. The existing storm drain system, therefore, would continue to adequately serve the project site under project conditions. As a result, the project would not result in substantial erosion or siltation, flooding, or additional sources of polluted runoff.

Impact HYD- 4: The project would not risk release of pollutants due to project inundation in flood hazard, tsunami, or seiche zones. ( Less than Significant Impact) As discussed in Section 4. 9 Hazards and Hazardous Materials, the proposed residential and storage facility buildings would not use or store substantial quantities of hazardous materials on -site. As discussed in Section 4. 10. 1. 2 Existing Conditions, the project site is not located within a 100- year flood hazard area or located in an area that is subject to flood risks associated with tsunamis or seiches. For these reasons, the project would not risk release of substantial pollutants due to inundation. ( Less than Significant Impact)
Impact HYD- 5: The project would not conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan. ( Less than Significant Impact)
The San Francisco Basin Plan provides a framework for state and local governments to meet water quality objectives and criteria to protect the beneficial uses of local aquifers, streams, marshes, and San Francisco Bay. Consistent with the San Francisco Basin Plan, the proposed project would comply with the MRP requirement to install LID treatment controls to treat stormwater runoff and implement the City standard conditions of approval COA HYD- 1. 1 identified under Impact HYD- 1. In addition, the project would decrease impervious surfaces on -site and would not result in any substantial depletion of groundwater supplies. Therefore, the project would not interfere with implementation of the 2021 Groundwater Management Plan.

For these reasons, the project would not conflict with water quality control plans or sustainable groundwater management plans. ( Less than Significant Impact) Terra Bella Public Storage & ALTA Housing Project 117 Initial Study City of Mountain View November 2022

Impact MIN- 1: The project would not result in the loss of availability of a known mineral resource that would be of value to the region and residents of the state. ( No Impact)
As discussed above in Section 4. 12. 1. 2 Existing Conditions, there are no known mineral resources on - site. Therefore, the proposed project would not result in the loss of availability of a known mineral resource that would be of value to the residents in the state or region. ( No Impact) Impact MIN- 2: The project would not result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan. ( No Impact)
The project site is not identified in the General Plan as containing any locally important mineral resources and no known mineral resources have previously been discovered on -site. The project, therefore, would not result in impacts to locally important mineral resource recovery sites. ( No Impact)

4. 13 NOISE
The following discussion is based on a Noise Assessment prepared by Illingworth & Rodkin, Inc. dated September 15, 2022. A copy of this report is included in Appendix J of this Initial Study.

4. 13. 1 Environmental Setting

4. 13. 1. 1 Background Information
Noise
Factors that influence sound as it is perceived by the human ear, include the actual level of sound, period of exposure, frequencies involved, and fluctuation in the noise level during exposure. Noise is measured on a decibel scale, which serves as an index of loudness. The zero on the decibel scale is based on the lowest sound level that the healthy, unimpaired human ear can detect. Each 10 decibel increase in sound level is perceived as approximately a doubling of loudness. Because the human ear cannot hear all pitches or frequencies, sound levels are frequently adjusted or weighted to correspond to human hearing. This adjusted unit is known as the A -weighted decibel, or dBA.

Since excessive noise levels can adversely affect human activities and human health, federal, state, and local governmental agencies have set forth criteria or planning goals to minimize or avoid these effects.

Noise guidelines are generally expressed using one of several noise averaging methods, including Leq, La, or CNEL.70 These descriptors are used to measure a location' s overall noise exposure, given that there are times when noise levels are higher ( e. g., when a jet is taking off from an airport or when a leaf blower is operating) and times when noise levels are lower ( e. g., during lulls in traffic flows on freeways or in the middle of the night). L. ax is the maximum A -weighted noise level during a measurement period.

Vibration
Ground vibration consists of rapidly fluctuating motions or waves with an average motion of zero.

Vibration amplitude can be quantified using Peak Particle Velocity ( PPV), which is defined as the maximum instantaneous positive or negative peak ofthe vibration wave. PPV has been routinely used to measure and assess ground -borne construction vibration. Studies have shown that the threshold of perception for average persons is in the range of 0. 008 to 0. 012 inches/ second ( in/ sec) PPV. 70 Leq is a measurement of average energy level intensity of noise over a given period of time. Day -Night Level (L,dn) is a 24- hour average of noise levels, with a 10 dB penalty applied to noise occurring between 10: 00 PM and 7: 00 AM. Community Noise Equivalent Level ( CNEL) includes an additional five dB applied to noise occurring between 7: 00 PM and 10: 00 PM. Where traffic noise predominates, the CNEL and Ldi, are typically within two dBA of the peak -hour Leq.

4. 13. 1. 2 Regulatory Framework
Federal and State
Federal Transit Administration Vibration Limits
The Federal Transit Administration ( FTA) has developed vibration impact assessment criteria for evaluating vibration impacts associated with transit projects. The FTA has proposed vibration impact criteria based on maximum overall levels for a single event. The impact criteria for groundbome vibration are shown in Table 4. 13- 1 below. There are established criteria for frequent events ( more than 70 events of the same source per day), occasional events ( 30 to 70 vibration events of the same source per day), and infrequent events ( less than 30 vibration events ofthe same source per day). These criteria can be applied to development proj ects in jurisdictions that lack vibration impact standards.

California Buildin4 Standards Code
The CBC establishes uniform minimum noise insulation performance standards to protect persons within new buildings housing people, including hotels, motels, dormitories, apartments, and dwellings other than single- family residences. Title 24 mandates that interior noise levels attributable to exterior sources not exceed 45 Ldn/ CNEL in any habitable room. Exterior windows must have a minimum Sound Transmission Class ( STC) of 40 or Outdoor -Indoor Transmission Class ( OITC) of 30 when the property falls within the 65 dBA Ldn noise contour for a freeway or expressway, railroad, or industrial source.

the vicinity of the airport, as well as aircraft occupants. 71 The CLUP includes noise exposure maps and guidelines intended to minimize the public' s exposure to excessive noise and safety hazards. The CLUP identifies the AIA. The AIA is a composite of areas surrounding the Airfield that are affected by noise, height, and safety considerations. Within the AIA, the CLUP establishes a ( 1) noise restriction area, ( 2) height restriction area, and ( 3) safety restriction area.

The Santa Clara County ALUC has jurisdiction over new land uses in the vicinity of airports, and establishes 65 dBA CNEL as the maximum allowable noise level considered compatible with residential uses. Recommendations made by the ALUC are advisory in nature to the local jurisdictions, not mandatory.

City of Mountain View 2030 General Plan
The purpose of the City of Mountain View 2030 General Plan Noise Element is to guide policies for addressing exposure to current and projected noise sources in Mountain View. The Noise Element includes a land use compatibility section which outlines acceptable outdoor noise environment standards for land use categories, as shown below in Table 4. 13- 2.

Terra Bella Public Storage & ALTA Housing Project 126 Initial Study City of Mountain View November 2022
Resolution No. 18773

Policy Description
NOI 1. 1 Land Use Compatibility. Use the Outdoor Noise Acceptability Guidelines as a guide for planning and development decisions.

NOI 1. 2 Noise - sensitive land uses. Require new development of noise - sensitive land uses to incorporate measures into the project design to reduce interior and exterior noise levels to the following acceptable levels:

New single-family developments shall maintain a standard of 65 dBA Ldn for exterior noise in private outdoor active use areas.

New multi -family residential developments shall maintain a standard of 65 dBA Ldn for private and community outdoor recreation use areas. Noise standards do not apply to private decks and balconies in multi -family residential developments.

Interior noise levels shall not exceed 45 dBA Ldn in all new single- family and multi -family residential units.

Where new single- family and multi -family residential units would be exposed to intermittent noise from major transportation sources such as train or airport operations, new construction shall achieve an interior noise level of 65 dBA through measures such as site design or special construction materials. This standard shall apply to areas exposed to four or more major transportation noise events such as passing trains or aircraft flyovers per day.

NOI 1. 3 Exceeding acceptable noise thresholds. If noise levels in the area of a proposed project would exceed normally acceptable thresholds, the City shall require a detailed analysis of proposed noise reduction measures to determine whether the proposed use is compatible. As needed, noise insulation features shall be included in the design of such projects to reduce exterior noise levels to meet acceptable thresholds, or for uses with no active outdoor use areas, to ensure acceptable interior noise levels.

NOI 1. 4 Site planning. Use site planning and project design strategies to achieve the noise level standards in NOI 1. 1 ( Land Use Compatibility) and in NOI 1. 2 ( Noise Sensitive Land Uses). The use of noise barriers shall be considered after all practical design -related noise measures have been integrated into the project design.

NOI 1. 5 Major roadways. Reduce the noise impacts from major arterials and freeways.

NOI 1. 6 Sensitive uses. Minimize noise impacts on noise -sensitive land uses, such as residential uses, schools, hospitals and child- care facilities.

NOI 1. 7 Stationary sources. Restrict noise levels from stationary sources through enforcement of the Noise Ordinance.

City of Mountain View Code of Ordinances
The City of Mountain View addresses noise regulations and goals in the zoning chapter of the City Code. The City' s codes help protect the community from exposure to excessive noise and also specify how noise is measured and regulated. Noise is also regulated through standard project conditions of approval, and the Mountain View Police Department and the City Attorney' s office enforce noise violations.

Construction noise impacts primarily occur when construction activities occur during noise -sensitive times of the day ( early morning, evening, or nighttime hours), the construction occurs in areas immediately adjoining noise - sensitive land uses ( e. g., residences), and/ or when construction duration lasts over an extended period oftime. Section 8. 70. 1 ofthe City Code restricts the hours of construction Terra Bella Public Storage & ALTA Housing Project 127 Initial Study City of Mountain View November 2022
Resolution No. 18773

activity to 7: 00 a.m. to 6: 00 p.m., Monday through Friday. No construction activity is permitted on Saturday, Sunday, or holidays without written approval from the City. Construction activities are defined to include any physical activity on the construction site or in the project' s staging area, including the delivery of materials.

The City of Mountain View also identifies limits on noise from stationary equipment ( such as heating, ventilation, and air conditioning mechanical systems, delivery truck idling, loading/ unloading activities, recreation activities, and parking lot operations) in Section 21. 26 of the City Code. The maximum allowable noise level is 55 dBA during the day and 50 dBA at night ( 10: 00 p. m. to 7: 00 a. m.), unless it has been demonstrated that such operation would not be detrimental to the health, safety, peace, morals, comfort or general welfare of residents subjected to such noise, and the use has been granted a permit by the Zoning Administrator.

4. 13. 1. 3 Existing Conditions
The noise environment at the proposed project site is currently dominated by vehicular traffic along US 101. Secondary noise sources would include vehicular traffic along Terra Bella Avenue. A summary of the noise levels measured on -site are included in Table 4. 13- 3 and Table 4. 13- 4 below.

The CEQA Guidelines state that a project would normally be considered to have a significant impact if noise levels conflict with adopted environmental standards or plans, or if noise levels generated by the project will substantially increase existing noise levels at noise -sensitive receivers on a permanent or temporary basis. CEQA does not define what noise level increase would be substantial. As discussed in CEQA Guidelines Section 15064( b), the determination of whether a project may have a significant effect on the environment calls for judgment on the part of the lead agency and must be based to the extent possible on scientific and factual data.

Impact NOI- 1: The project would not result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies. ( Less than Significant Impact) Construction Noise
Project Construction
Noise impacts resulting from construction depend upon the noise generated by various pieces of construction equipment, the timing and duration of noise -generating activities, and the distance between construction noise sources and noise -sensitive areas. Construction noise impacts primarily result when construction activities occur during noise -sensitive times of the day ( e. g., early morning, evening, or nighttime hours), the construction occurs in areas immediately adjoining noise -sensitive land uses, or when construction lasts over extended periods of time.

Construction of the entire project would take approximately 30 months and would be split into two main phases. The residential building and the westernmost storage facility building (Building 1) would Terra Bella Public Storage & ALTA Housing Project 130 Initial Study City of Mountain View November 2022
Resolution No. 18773

be constructed in Phase 1 and would take approximately 22 months to complete, with seven of those months consisting of overlapping construction at both portions of the project site. The easternmost storage facility building (Building 2) would be constructed in Phase 2 and would take approximately 12 months to complete. Project construction activities would include demolition, site preparation, grading and excavation, building construction, architectural coatings, and paving.

The City of Mountain View does not establish noise level thresholds for construction activities. In past practice, the City has required standard construction noise reduction measures if the hourly average noise levels exceed 60 dBA Leq, and the ambient by at least five dBA Leq, for a period of more than one year at adjacent residential land uses to reduce impacts to a less than significant level. The City currently utilizes the noise limits established by the Federal Transit Administration ( FTA) to identify potential impacts due to substantial temporary construction noise, which are 80 dBA Leq at residential land uses and 90 dBA Leq at commercial and industrial land uses during daytime hours.

As described in additional detail in Appendix J, the nearest existing residence is located approximately 445 feet east as measured from the center ofthe project site.' A new residential building approximately 515 feet west ofthe center ofthe project site is under construction, and would be constructed when the proposed project begins construction. The nearest non-residential use is the adjacent office building approximately 80 feet southwest of the center of the project site. The project specific analysis determined that construction noise levels would potentially reach 74 dBA Leq on occasion at the nearest residential land use, and 80 dBA Leq at the nearest existing commercial land use, as calculated from the center ofthe project site phases. The potential highest noise level for both the nearest residence and office use would occur in the grading and excavation phase of construction. Construction noise levels would not exceed 80 dBA Leq at residential land uses near the site or 90 dBA Leq at the commercial land uses near the site, however, comparing against City' s past practices, project construction would exceed one year and would be subject to the following City standard conditions of approval to reduce construction noise impacts to surrounding land uses.

City Standard Conditions of Approval:

COA N0I- 1. 1: The project shall implement the following measures:

Work Hours - No work shall commence on the job site prior to 7: 00 a. m. nor continue later than 6: 00 p.m., Monday through Friday, nor shall any work be permitted on Saturday or Sunday or any holiday unless prior approval is granted by the Chief Building Official. At the discretion of the Chief Building Official, the general contractor or the developer may be required to erect a sign at a rominent location on the construction site to advise subcontractor and material suppliers ofthe working hours. Violation ofthis condition of approval may be subject to the penalties outlined in Section 8. 6 ofthe City Code and/ or suspension of building permits.

Notice of Construction - The applicant shall notify neighbors within 300 feet ofthe project site ofthe construction schedule in writing, prior to construction. 72 Similar to the air quality analysis, the noise assessment conservatively assumed that the former residential building east of the project site, currently occupied by a roofing company, is the closest residence.

Terra Bella Public Storage & ALTA Housing Project 131 Initial Study City of Mountain View November 2022
Resolution No. 18773

A copy ofthe notice and the mailing list shall be submitted prior to issuance of building permits.

Construction Noise Reduction - The following noise reduction measures shall be incorporated into construction plans and contractor specifications to reduce the impact of temporary construction - related noise on nearby properties: a. comply with manufacturer' s muffler requirements on all construction equipment engines; b. turn off construction equipment when not in use, where applicable; c. locate stationary equipment as far as practicable from receiving properties; d. use temporary sound barriers or sound curtains around loud stationary equipment ifthe other noise reduction methods are not effective or possible; e. and shroud or shield impact tools and use electric powered rather than diesel -powered construction equipment.

Disturbance Coordinator - The applicant shall designate a " disturbance coordinator" who shall be responsible for responding to any local complaints regarding construction noise. The coordinator ( who may be an employee ofthe general contractor) shall determine the cause ofthe complaint and will require that reasonable measures warranted to correct the problem be implemented. A telephone number of the noise disturbance coordinator shall be conspicuously posted at the construction site fence and on the notification sent to neighbors adjacent to the site. The sign must also list an emergency after- hours contact number for emergency personnel.

The project, with the implementation of City standard conditions of approval COA NOI- 1. 1, would result in less than significant construction noise impacts by notifying neighbors of the project construction schedule, designating a disturbance coordinator, working within the allowed construction hours, and implanting noise reduction measures. ( Less than Significant Impact) Cumulative Construction
As discussed in Section 4. 3 Air Quality under Impact AIR- 1, there are two other development proj ects within 1, 000 feet of the project site:
1001 North Shoreline Boulevard ( 150 feet west) — two buildings totaling 303 dwelling units and a five level parking garage( approved)
1155 & 1185 Terra Bella Avenue ( 400 feet southwest) — 20, 000- square foot office building proposed/ pending)
The 1001 North Shoreline Boulevard project is developing two residential buildings. The first building is currently under construction approximately 515 feet west from the center ofthe 1020 and 1040 Terra Bella Avenue portion ofthe project site and is scheduled to be completed before construction of Phase 1 at the 1020 and 1040 Terra Bella Avenue portion ofthe project site begins. Construction ofthe second building at 1001 North Shoreline Boulevard is to begin in early 2024 and its construction would overlap with the construction of Phase 1 and 2 at the proj ect site. During this overlapping construction period, temporary combined construction noise levels at nearby receptors may be up to two dBA higher than if only one project was under construction. Construction at nearby 1155 & 1185 Terra Bella Avenue if approved) is scheduled to begin early 2024, which could overlap with construction at the project Terra Bella Public Storage & ALTA Housing Project 132 Initial Study City of Mountain View November 2022
Resolution No. 18773

site and 1001 North Shoreline Boulevard. During this overlapping construction period, temporary combined construction noise levels at nearby receptors may be up to three dBA higher than if only one project was under construction. However, in no case would construction noise levels exceed the 80 dBA noise limit at existing nearby residential properties or the 90 dBA noise limit at existing nearby commercial properties. Therefore, cumulative construction noise impact would be less than significant.

Less than Significant Cumulative Impact)
Operational Noise
Mechanical Equipment Noise
The proposed residential and commercial structures would include mechanical equipment such as air conditioning, heating systems, and exhaust fans. The project would implement the following City standard condition of approval to ensure that impacts from mechanical equipment noise would meet stationary equipment noise limits identified in City Code Section 21. 26. During the building permit process, a project -specific acoustical analysis that demonstrates compliance with day and nighttime noise limits at the adjoining residentially used property would be required as part of the permit application.

City Standard Condition of Approval:

COA NOI- 1. 2: Mechanical Equipment - The noise emitted by any mechanical equipment shall not exceed a level of 55 dB( A) during the day or 50 dB( A) during the night, 10: 00 p.m. to 7: 00 a.m., when measured at any location on the adjoining residentially used property.

A qualified acoustical consultant shall be retained to review mechanical noise as these systems are selected to determine specific noise reduction measures necessary to reduce noise to comply with the City' s noise level requirements. Noise reduction measures could include, but are not limited to, selection of equipment that emits low noise levels and installation of noise barriers, such as enclosures and parapet walls, to block the line -of -sight between the noise source and the nearest receptors.

Alternate measures may include locating equipment in less noise -sensitive areas, such as the rooftop of the buildings away from the building' s edge nearest the noise -sensitive receptors, where feasible.

With implementation of the above City standard condition of approval COA N0I- 1. 2, project mechanical equipment would not substantially increase noise levels in the project area. ( Less than Significant Impact)
Project Traffic
A significant noise impact would occur iftraffic generated by the project would substantially increase noise levels at sensitive receivers in the vicinity. A substantial increase would occur ifthe noise level increase is three dBA DNL or greater, as existing noise levels at the nearby residences in the area would exceed 60 dBA DNL. Generally, traffic volumes need to double to result in a perceptible ( three dB) noise increase. As discussed in the project -specific Transportation Analysis, the project would result in a net increase of 996 new daily vehicle trips. 7' The main source of traffic noise at the prcj ect 73 Hexagon Transportation Consultants, Inc. 1020- 1040 Terra Bella Avenue Transportation Analysis. November 22, 2022. Page 14.

Terra Bella Public Storage & ALTA Housing Project 133 Initial Study City of Mountain View November 2022
Resolution No. 18773

site is from US 101, and the number oftrips generated by the project would not double traffic volumes on US 101. Therefore, the project -generated traffic would not increase ambient noise levels by three dBA DNL or more. For this reason, the project -generated traffic noise would result in a less than significant impact. ( Less than Significant Impact)
Cumulative Traffic
Cumulative traffic noise could also result from the traffic generated by the project when added to the traffic generated by other reasonably foreseeable projects. Cumulative traffic conditions were reviewed to determine if the proposed project would make a cumulatively considerable contribution to significant traffic noise increases expected in the area. A significant cumulative traffic noise increase would occur if two criteria are met: 1) if the cumulative traffic noise level increase was three dBA DNL or greater for future levels exceeding 60 dBA DNL or was five dBA DNL or greater for future levels at or below 60 dBA DNL; and 2) ifthe project would expose persons to or generate noise levels that would exceed applicable noise standards presented in the General Plan. Cumulative traffic noise levels were calculated to increase by less than two dBA DNL in the project vicinity. For these reasons, the cumulative traffic noise impact would be less than significant. ( Less than Significant Cumulative Impact)
Impact NOI- 2: The project would not result in generation of excessive groundborne vibration or groundborne noise levels. ( Less than Significant Impact with Mitigation Incorporated)
Construction activities associated with the project may generate perceptible vibration when heavy equipment or impact tools ( e. g., jackhammers, hoe rams) are used. Construction activities would include site demolition, preparation work, foundation work, and new building framing and finishing.

The proposed project is not expected to require pile driving, which can cause excessive vibration.

As discussed in Section 4. 13 Cultural Resources, no historical buildings have been identified in proximity to the project site. The project -specific Noise and Vibration Assessment used two groundborne vibration levels to determine the threshold of significance at which buildings in the project vicinity would have the potential to be subject to a significant vibration impact. These thresholds were groundborne vibration levels in excess of 0. 5 in/ sec PPV for surrounding commercial/ industrial structures and 0. 3 in/ sec PPV for surrounding residential buildings. Table 4. 13- 5 shows the estimated vibration levels at nearby structures resulting from operation of construction equipment at the proj ect site.

As shown in Table 4. 13- 5, operation of heavy equipment during the construction process would result in vibration levels of up to 0. 575 in/ sec PPV for the commercial uses to the south of the project site.

This would exceed the 0. 5 in/ sec PPV threshold and would have the potential to result in cosmetic damage, which would be a significant impact. To reduced potential vibration impacts resulting from construction activities, the City requires implementation of the following City standard condition of approval.

City Standard Condition of Approval:

COA N0I-2. 1: Vibration Best Management Practices Construction Measures:

Avoid impact pile driving and drill piles instead where possible. Drilled piles cause lower vibration levels where geological conditions permit their use.

Avoid using vibration rollers and tampers near sensitive areas.

In areas where project construction is anticipated to include vibration generating activities, vibration studies shall be conducted to determine the Terra Bella Public Storage & ALTA Housing Project 135 Initial Study City of Mountain View November 2022
Resolution No. 18773

areas ofimpact and to present appropriate mitigation measures that may include the following:
o
Identification of sites that would be exposed to project vibration compaction activities and could result in vibration impacts to structures;
o Develop a vibration monitoring and contingency plan;
o Construction contingency plan; and
o Conduct post -survey on structures where either monitoring has indicated high levels or complaints of damage have been made.

In compliance with the above City standard condition of approval, a vibration study was conducted, and the following mitigation measure is required.

Mitigation Measure:

MM NOI- 2. 1: The following measures shall be implemented during construction to reduce vibration levels to 0. 5 in/ sec PPV or less at adjacent commercial/ industrial buildings south of the site.

Place operating equipment on the construction site as far as possible from vibration -sensitive receptors.

Use smaller vibratory rolling equipment, for example the Caterpillar model CP433E vibratory compactor, within 15 feet of the adjacent commercial/ industrial buildings south of the site to reduce vibration levels to

0. 5 in/ sec PPV or less.

Select demolition methods not involving impact tools.

Avoid dropping heavy equipment, such as a clam shovel drop, within 15 feet of the adjacent commercial/ industrial buildings south of the site, and use alternative methods for breaking up existing pavement, such as a pavement grinder.

Designate a person responsible for registering and investigating claims of excessive vibration. The contact information of such person shall be clearly posted on the construction site.

With implementation of City standard condition of approval COA NOI-2. 1 and mitigation measure NM NOI- 2. 1, impacts related to groundborne vibration at adjacent structures would be reduced to a less than significant level by avoiding the use of high vibration impact equipment near sensitive receptors, using lower vibration impact construction methods and equipment, and designating a person on the construction site to respond to and address claims of excessive vibration.

Impact NOI- 3: The project would not be located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport. The project would not expose people residing or working in the project area to excessive noise levels. ( Less than Significant Impact)
The nearest airport to the project site is Moffett Federal Airfield, which is approximately 1. 2 miles northeast of the site. While aircraft flyovers from Moffett Federal Airfield would at times be audible at the outdoor use areas on the project site, the site is outside ofthe Airfield' s 65 dBA CNEL noise contour area. Therefore, the project would not expose people residing or working in the project area to excessive noise levels. ( Less than Significant Impact)

4. 13. 3 Non- CEOA Effects
Per California Building Industry Association v. Bay Area Air Quality Management District, 62 Cal. 4th 369 ( BIA v. BAAQMD), effects of the environment on the project are not considered CEQA impacts. The following discussion is included for informational purposes only because the City has policies ( including General Plan Policies NOI 1. 2, NOI 1. 3, NOI, 1. 4, NOI 1. 5, and NOI 1. 6 identified in Section 4. 13. 1. 2 Regulatory Framework) that address existing noise conditions affecting a proposed proj ect.

Future Exterior Noise Environment
The proposed residential building would face Terra Bella Avenue. The primary outdoor use areas would be a courtyard located on the third story on the south side of the building, enclosed by three residential levels on the north, east, and west sides, and the pedestrian plaza area on Terra Bella Avenue. The acoustical shielding provided by the building would reduce the noise level in the courtyard and pedestrian plaza to 51 dBA DNL and 64 dBA DNL, respectively, which is below the City' s maximum acceptable outdoor noise exposure level for multiple -family residential areas of 65 dBA DNL.

The worst -case noise exposure for the storage facility buildings would remain at 75 dBA DNL, with Building 1 being partially shielded by an elevated ramp that reduces noise levels to 72 dBA at some portions of the building. The noise exposure at the storage facility manager' s apartment unit would remain at 72 dBA DNL. No outdoor -use areas are planned around the storage buildings.

Future Interior Noise Environment
Residential units along the northeastern fagade of the residential building nearest to US 101 and the manager' s apartment unit in Storage Building 1 would be exposed to exterior noise levels as high as 72 dBA DNL. General Plan Policy NOI 1. 2 requires that indoor noise levels for residences not exceed 45 dBA DNL. To meet the indoor noise level standard would require at least 27 decibels of attenuation to meet the required indoor level of 45 dBA DNL
The project would be required to implement the following City standard condition of approval.

Terra Bella Public Storage & ALTA Housing Project 137 Initial Study City of Mountain View November 2022
Resolution No. 18773

City Standard Condition of Approval:

COA NOI-4. 1: The project would implement the following measures.

Interior Noise Levels - Construction drawings must confirm that measures have been taken to achieve an interior noise level of 45 dB( A)L& that shall be reviewed and approved by a qualified acoustical consultant prior to building permit submittal.

Site Specific Building Acoustical Analysis - A qualified acoustical consultant shall review final site plans, building elevations, and floor plans prior to construction to calculate expected interior noise levels as required by State noise regulations. Project -specific acoustical analyses are required by the California Building Code to confirm that the design results in interior noise levels reduced to 45 dB( A)DNL or lower. The specific determination of what noise insulation treatments are necessary shall be completed on a unit -by -unit basis. Results of the analysis, including the description of the necessary noise control treatments, shall be submitted to the City along with the building plans and approved prior to issuance of a building permit. Building sound insulation requirements shall include the provision of forced -air mechanical ventilation for all residential units as recommended by the qualified acoustical consultant, so that windows can be kept closed at the occupant' s discretion to control noise.

Special building techniques ( e. g., sound -rated windows and building facade treatments) shall be implemented as recommended by the qualified acoustical consultant to maintain interior noise levels at or below acceptable levels. These treatments shall include, but are not limited to, sound -rated windows and doors, sound -rated wall construction, acoustical caulking, protected ventilation openings, etc.

The site -specific noise assessment conducted for the project found the proposed buildings, with standard construction and incorporation of adequate forced -air mechanical ventilation, can be feasibly designed to reduce noise levels below the 45 dBA DNL threshold for the residential units in the residential building and manager' s apartment unit in Storage Building 1.

The performance method enforced in the CALGreen Code requires that interior noise levels for nonresidential use be maintained at 50 dBA Leq( 1_ hr) or less during hours of operation. The proposed storage facility buildings would be exposed to exterior noise levels between 72 and 75 dBA DNL along US 101. The worst -case hourly Leq would be 73 dBA at this location. Standard construction materials for commercial uses would provide approximately 25 dBA of noise reduction in interior spaces and the inclusion of adequate forced -air mechanical ventilation systems would provide an additional five dBA reduction which would satisfy the daytime threshold of 50 dBA Leq( 1- hr).

Implementation ofthe above City standard condition of approval would ensure that interior noise levels are reduced to acceptable levels by utilizing specific design measures and construction materials.

Plan Bay Area 2050 is a long- range plan for the nine -county San Francisco Bay Area that provides strategies that increase the availability of affordable housing, support a more equitable and efficient economy, improve the transportation network, and enhance the region' s environmental resilience. Plan Bay Area 2050 promotes the development of a variety of housing types and densities within identified Priority Development Areas ( PDAs). PDAs are areas generally near existing job centers or frequent transit that are locally identified for housing and job growth. 75 ABAG allocates regional housing needs to each city and county within the San Francisco Bay Area, based on statewide goals. These allocations are designed to lay the foundation for Plan Bay Area 2050' s long-term envisioned growth pattern for the region. ABAG also develops a series of forecasts and models to project the growth of population, housing units, and jobs in the Bay Area.

A project can induce substantial population growth by proposing new housing beyond projected or planned development levels, generating demand for housing as a result of new businesses, extending roads or other infrastructure to previously undeveloped areas, or removing obstacles to population growth ( e. g., expanding capacity of a wastewater treatment plant beyond that necessary to serve planned growth).

The project site currently has a General Plan designation of General Industrial, which does not allow residential development and, therefore, was not projected to accommodate any population or housing growth at the buildout ofthe General Plan. The proposed project would construct a 108- unit residential building, and potentially an additional unit for the storage facility manager in Building 1 of the proposed storage facility, which would result in approximately 256 new residents more than what was 76 California Department of Finance.

The Quimby Act (included within Government Code Section 66477) requires local governments to set aside parkland and open space for recreational purposes. It provides provisions for the dedication of parkland and/ or payment of fees in lieu of parkland dedication to help mitigate the impacts from new residential developments. The Quimby Act authorizes local governments to establish ordinances requiring developers of new residential subdivisions to dedicate parks, pay a fee in lieu of parkland dedication, or perform a combination ofthe two.

Government Code Section 65995 through 65998
California Government Code Section 65996 specifies that an acceptable method of offsetting a project' s effect on the adequacy of school facilities is the payment of a school impact fee prior to the issuance of a building permit. Government Code Sections 65995 through 65998 set forth provisions for the payment of school impact fees by new development by " mitigating impacts on school facilities that occur ( as a result of the planning, use, or development of real property" ( Section 65996[ a]). The legislation states that the payment of school impact fees " are hereby deemed to provide full and complete school facilities mitigation" under CEQA ( Section 65996[ b]).

Developers are required to pay a school impact fee to the school district to offset the increased demands on school facilities caused by the proposed residential development project.

Station Five is the nearest fire station to the project site, and the site is less than 1. 5 miles from three other MVFD fire stations. In addition, the project would be constructed to comply with current Fire Code standards as adopted by the City of Mountain View, and MVFD would review project plans to ensure to adequate fire safety and prevention measures on -site.

( Less than Significant Impact)
As discussed in Impact PS- 1, the project would result in an increase of up to 109 residential units and approximately 256 new residents. The project would also expand the existing storage facility. The addition of approximately 256 new residents and additional customers generated by the storage facility would result in an incremental increase in the demand for police protection services in Mountain View.

The project site is located in an area that is currently served by the MVPD. In addition, the project would include nighttime security lighting, privately accessed control points, and surveillance cameras.

These safety features are incorporated to minimize and deter the opportunity for criminal activity. The City' s General Plan policies ( PSA 1. 1 and PSA 2. 7) ensure that the City maintains adequate police staffing and performance levels while continually exploring ways to improve police effectiveness.

Less than Significant Impact)
The project would develop up to 109 residential units ( including two manager' s units). Based on the most recently available student generation rates provided by MVWSD and MVLASD, the project would generate approximately 61 elementary and middle school students and 34 high school students. 86 As discussed in Section 4. 15. 1. 2, both Theuerkauf Elementary School and Crittenden Middle School have existing capacity to accommodate project generated students based on current enrollment numbers. Therefore, the addition of 61 elementary and middle school students would not require the expansion of those schools or construction of any new school facilities. As of the end of the 2021 to 2022 school year, Mountain View High School is over capacity by 770 students. 87 The school currently utilizes portable classrooms in addition to permanent education facilities to accommodate the additional students. The construction of permanent classroom facilities is underway through Measure E bond program funding and has undergone separate environmental review. The construction of these additional facilities would result in an overall capacity of 2, 379 students, which would be sufficient to accommodate the currently enrolled students in addition to the approximately 34 new students that would be generated by this proj ect. 88
As required by state law ( Government Code Section 65996), the project proponent shall pay the appropriate school impact fees to offset and mitigate the increased demands on school facilities caused by the project.

Resolution No. 18773

Impact PS- 4: The project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for parks. ( Less than Significant Impact)
As discussed in Section 4. 16. 1. 1, the City Code exempts affordable housing units from paying park land dedication or in -lieu fees. Since the project would provide 100-percent ( excluding manager' s units) affordable housing units, it would not be required to contribute the park land dedication fee that is typically required for market -rate residential developments in the City. The new residents generated by the proposed project would incrementally increase the use of existing recreational facilities in the project area. The residential portion of the proposed project would include approximately 10, 300 square feet of common amenity space on the podium deck of the building which would help offset the increase in demand on parks and recreational facilities. The ground -floor of the residential building would also include landscaped seating areas and an entry plaza. The inclusion of landscaping areas, walking paths, lounge areas, and play equipment on -site would offset the project' s demand on City park facilities. As such, the project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities. ( Less than Significant Impact)
Impact PS- 5: The project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for other public facilities. ( Less than Significant Impact)
Implementation of the proposed project would contribute to an incremental increase in demand for other public facilities, such as libraries, because it would add new residents to the City. The single library in the City currently serves the existing population of 83, 864, and the addition of the approximately 256 project residents would result in a potential increase in patrons of less than 0. 3 percent. This incremental increase in demand would not require the construction or expansion of new library facilities. ( Less than Significant Impact)

State
Government Code Section 66477
The Quimby Act (included within Government Code Section 66477) requires local governments to set aside parkland and open space for recreational purposes. It provides provisions for the dedication of parkland and/ or payment of fees in lieu of parkland dedication to help mitigate the impacts from new residential developments. The Quimby Act authorizes local governments to establish ordinances requiring developers of new residential subdivisions to dedicate parks, pay a fee in lieu of parkland dedication, or perform a combination ofthe two.

Local
Mountain View 2030 General Plan
The General Plan contains goals and policies to avoid significant impacts due to recreation impacts.

The following goals and policies are applicable to the proposed project.

Policy Description
Parks, Open Space and Community Facilities
POS 1. 1 Additional parkland. Expand park and open space resources to meet current City standards for open acreage and population in each neighborhood.

POS 1. 2 Recreation facilities in new residential developments. Require new development to provide park and recreation facilities.

POS 2. 6 Diverse park amenities. Design parks to address a range of activities for diverse populations.

POS 4. 2 Park design. Implement high -quality park amenities and design.

POS 6. 1 Citywide network of pathways. Develop a citywide network of pedestrian and bicycle pathways to connect neighborhoods, employment centers, open space resources and major destinations within the city.

City of Mountain View Code of Ordinances
Chapter 41 of the City Code contains a Park Land Dedication Ordinance, which sets requirements for park land dedication or in -lieu fees. The City requires developers to dedicate at least three acres ofpark land for each 1, 000 persons who will live in a new housing project ( owned or rented), or to pay an in - lieu fee that would be used to offset the increased demands on park facilities. The City also allows developers to propose, for City Council consideration, a POPA space within a residential development site for park land credit, reducing the land or in -lieu fee obligation generated by the development.

Section 41. 11 ofthe City Code exempts affordable housing units from being counted towards the total number of dwelling units used to calculate the park land dedication requirement.

4. 17. 1. 1 Regulatory Framework
State
Regional Transportation Plan
MTC is the transportation planning, coordinating, and financing agency for the nine -county San Francisco Bay Area, including Santa Clara County. MTC is charged with regularly updating the Regional Transportation Plan, a comprehensive blueprint for the development of mass transit, highway, airport, seaport, railroad, bicycle, and pedestrian facilities in the region. MTC and ABAG adopted Plan Bay Area 2040 in July 2017, which includes a Regional Transportation Plan to guide regional transportation investment for revenues from federal, state, regional and local sources through 2040.

Senate Bill 743
SB 743 establishes criteria for determining the significance of transportation impacts using a vehicle miles traveled ( VMT) metric intended to promote the reduction of GHG emissions, the development of multimodal transportation networks, and a diversity of land uses. Specifically, SB 743 requires the replacement of automobile delay —described solely by level of service ( LOS) or similar measures of vehicular capacity or traffic congestion —with VMT as the recommended metric for determining the significance of transportation impacts. The Governor' s Office of Planning and Research ( OPR) approved the CEQA Guidelines implementing SB 743 on December 28, 2018. Local jurisdictions are required to implement a VMT policy by July 1, 2020.

SB 743 did not authorize OPR to set specific VMT impact thresholds, but it did direct OPR to develop guidelines for jurisdictions to utilize. CEQA Guidelines Section 15064. 3( b)( 1) describes factors that might indicate whether a development project' s VMT may be significant. Notably, projects located within 0. 50 mile of transit should be considered to have a less than significant transportation impact based on OPR guidance.

Regional and Local
Congestion Management Program
VTA oversees the Congestion Management Program ( CMP), which is aimed at reducing regional traffic congestion. The relevant state legislation requires that urbanized counties in California prepare a CMP in order to obtain each county' s share of gas tax revenues. State legislation requires that each CMP define traffic LOS standards, transit service standards, a trip reduction and transportation demand management plan, a land use impact analysis program, and a capital improvement element. VTA has Terra Bella Public Storage & ALTA Housing Project 152 Initial Study City of Mountain View November 2022

review responsibility for proposed development projects that are expected to affect CMP- designated intersections.

City of Mountain View 2030 General Plan
The following transportation -related policies from the General Plan are applicable to the proj ect.

Policy Description
Land Use and Design
LUD 3. 1 Land use and transportation. Focus higher land use intensities and densities within 0. 5 mile of public transit service and along major commute corridors.

LUD 8. 5 Pedestrian and bicycle amenities. Encourage attractive pedestrian and bicycle amenities in new and existing developments, and ensure that roadway improvements address the needs of pedestrians and bicyclists.

LUD 9. 4 Enhanced pedestrian activity. Ensure commercial development enhances pedestrian activity through these strategies:

Encourage the first level of the building to occupy a majority of the lot' s frontage, with exceptions for vehicle and pedestrian access Allow for the development of plazas and dining areas
Encourage the maj ority of a building' s ground floor frontage to provide visibility into the building by incorporating windows and doors
Require that ground floor uses be primarily pedestrian -oriented Ensure pedestrian safety and access when designing parking areas and drive - through operations
Minimize driveways
LUD 17. 2 Transportation Demand Management strategies. Require development to include and implement Transportation Demand Management strategies.

Mobility
MOB 1. 5 Public accessibility. Provide traffic calming, especially in neighborhoods and around schools, parks, and gathering places.

MOB 1. 6 Traffic calming. Provide traffic calming, especially in neighborhoods and around schools, parks, and gathering places.

MOB 8. 3 Multi -modal transportation monitoring. Monitor the effectiveness of policies to reduce vehicle miles traveled ( VMT) per service population by establishing transportation mode share targets and periodically comparing travel survey data to established targets.
2030 General Plan Action Item MOB 8. 1. 3
General Plan Action Item MOB 8. 1. 3 established interim Level of Service ( LOS) standards for the City to use based on the LOS standards from the 1992 General Plan. These standards include a target peak hour LOS policy of LOS D for all intersections and roadway segments, except for intersections and street segments within the Downtown Core and San Antonio areas and intersections and street segments on CMP designated roadways in Mountain View which have a target of LOS E.

Terra Bella Public Storage & ALTA Housing Project 153 Initial Study City of Mountain View November 2022
Resolution No. 18773

Mountain View VMT Policy
The Mountain View City Council adopted a Vehicle Miles Traveled Policy on June 30, 2020, which replaces LOS with VMT as the metric for determining a significant transportation impact under CEQA consistent with SB 743. The City' s VMT policy includes screening criteria for projects which are presumed to have a less than significant transportation impact. Specifically, the City' s VMT Policy states that projects would have a less than significant VMT impact and do not require further proj ectspecific VMT analysis ifthe prof ect meets the screening criteria for small prof ect screening, map -based screening, transit screening, or affordable housing screening. Projects determined by the City to be local -serving retail would also be exempt from being required to conduct a detailed CEQA VMT analysis.

Mountain View Comprehensive Modal Plan
The City identifies the level of comfort for pedestrians on any given roadway using the Pedestrian Quality of Service ( PQOS) metric. The Mountain View Comprehensive Modal Plan ( AccessMV) identifies the continuity or gaps in the City' s pedestrian facilities and identifies PQOS scoring ranging from 1 to 5. A higher PQOS score indicates a low quality of service. The PQOS metric covers the following factors:

Proximity to a variety of destinations and amenities
Street connectivity and directness of routes to destinations Presence of a continuous network of pedestrian facilities Motor vehicle traffic speed; and
Street width and intersection conditions
The City also identifies the perceived comfort and safety of existing roads and bikeway facilities from the perspective of cyclists using the Bicycle Level of Traffic Stress ( BLTS) metric. Accessw identifies the BLTS scoring ranging from 1 to 4. A higher BLTS score indicates that the bikeway is comfortable for a more confident adult. A BLTS score of 1 is comfortable for all ages and abilities, a BLTS score of 2 is comfortable for an average adult, while a BLTS score of 4 indicates that the streets are comfortable only for highly confident riders. The metric ( ranging from 1 to 4) in the AccessMV document covers the following factors:

Number of through lanes or street width
Posted speed limit or prevailing vehicle speed
Presence and type of bicycle facilities
Presence of traffic signals
Shoreline Boulevard Transportation Corridor Study
In November 2014, the Mountain View City Council approved the Shoreline Boulevard Transportation Corridor Study which determined the feasibility of, and developed a conceptual design for, integrated transit, bicycle, and pedestrian facilities in the Shoreline Boulevard Corridor from the Downtown Transit Center to North Bayshore. The Corridor Study provided a phasing program for the transportation improvements to achieve the North Bayshore commute mode -share goals and identified recommended Shoreline Boulevard bus lane and utility improvements.

2015 Bicycle Transportation Plan
The 2015 Bicycle Transportation Plan ( BTP) provides a vision, strategies, and actions for improving and encouraging bicycle travel in and through the City. The 2015 BTP also expands on the City' s 2030 General Plan mobility goals by more specifically addressing bicycle -related needs of the community. The 2015 BTP proposes Class IV cycle tracks along Shoreline Boulevard and Moffett Boulevard and a Class 11 full time bike lane along Middlefield Road.

2030 General Plan Action Item MOB 8. 1. 3
Compared to existing conditions, the project is estimated to generate 996 net new daily vehicle trips, with 68 trips during the AM peak hour, and 98 trips during the PM peak hour. While a project' s effect on automobile delay is no longer considered an impact under CEQA, local jurisdictions have roadway LOS standards. Per 2030 General Plan Action Item MOB 8. 1. 3, the City' s interim standard for signalized intersections is LOS D. The City does not have an adopted level of service standard for unsignalized intersections; however, the City strives to maintain LOS D for unsignalized intersections.

As discussed in more detail in Appendix K, the results of the LOS analysis conducted for the project show that one signalized intersection ( Shoreline Boulevard and US 101 northbound offramp/ La Avenida Street) would have a substandard LOS F with or without the project being constructed, and one unsignalized intersection ( Linda Vista Avenue and Middlefield Road) would have its LOS degrade from LOS D to LOS E during the PM peak hour under project conditions. Although the signalized intersection ( Shoreline Boulevard and US 101 northbound offramp/ La Avenida Street) would have a substandard LOS in the future, the increase in average critical delay would not be greater than four seconds, therefore, no adverse effect would be caused by the project. In addition, the residential development proposes to implement a TDM plan, which is estimated to reduce the residential vehicle trips by 15 percent. With the implementation of a TDM plan, the PM peak hour would no longer degrade to LOS E and would not have an adverse effect on traffic operations at this intersection.

Furthermore, the unsignalized intersection does not have volume of at least 100 vehicles per hour, it does not warrant installation of a traffic signal. The project is consistent with General Plan Action Item MOB 8. 1. 3. ( Less than Significant Impact)

Transit Facilities
As described in Section 4. 17. 1. 2 Existing Conditions, the project site is currently served by transit routes with existing bus stops proximate to the site that facilitate travel to the MVTC ( which provides access to Caltrain and VTA light rail service) and nearby employment centers. The prof ect- specific TA estimated that the addition of project residents could result in a slight increase in transit use that would equate to approximately two to three new transit riders during AM and PM peak hours. That projected increase would be minimal and existing transit services would be able to accommodate the additional riders. The City identified Shoreline Boulevard bus lane and utility improvements in the Shoreline Boulevard Transportation Corridor Study that would construct several improvements at the intersection of Terra Bella Avenue and North Shoreline Boulevard, including four new bus stops and dedicated bus lanes in with direction. Implementation of the project would not interfere with these planned improvements. Based on this discussion, the project would not conflict with a program, plan, ordinance or policy addressing transit. (Less than Significant Impact) Bicycle Facilities
As described in Section 4. 17. 1. 2 Existing Conditions, existing bicycle facilities near the project site are limited to Class 11 striped bike lanes on North Shoreline Boulevard and lanes that are available part-time on Middlefield Road. Shoreline Boulevard, Middlefield Road, and Moffett Boulevard have a BLTS score of 3 or more, and the project would add bicyclist demand to these roadways. The City' s 2015 BTP proposes Class IV cycle tracks along Shoreline Boulevard and Moffett Boulevard and a Class 11 full time bike lane along Middlefield Road. In addition, the City' s Shoreline Boulevard Bus Lane and Utility Improvements project, currently in implementation, would upgrade the bicycle facilities along Shoreline Boulevard, between US 101 and Montecito Avenue with protected bike lanes.

These planned improvements by the City of Mountain View would increase bicyclist comfort and safety while improving the BLTS and are consistent with the guidelines described in the City' s Comprehensive Modal Plan. The North Bayshore Precise Plan also identified a new Bicycle and Pedestrian Overcrossing that would provide a dedicated overcrossing to bicyclists and pedestrians.

Implementation ofthe project would not interfere with any of these identified improvements or result in the need for additional improvements.

The residential portion of the project proposes a total of 108 long-term bicycle parking spaces located in a secure storage room on the ground floor of the residential building and 12 short- term bicycle parking spaces on racks outside of the building adjacent to Terra Bella Avenue. The storage facility portion of the project would provide short-term bicycle parking spaces on racks outside of the rental office. The amount ofprovided bicycle parking spaces would comply with City requirements. For these reasons, the project would not conflict with any programs, plans, ordinances, or policies addressing bicycle facilities. ( Less than Significant Impact)

As discussed in Section 4. 17. 1. 2 Existing Conditions, pedestrian facilities in immediate site vicinity include continuous sidewalks on both sides of all surrounding streets, including Terra Bella Avenue, Linda Vista Avenue, and San Rafael Avenue. In addition, there are crosswalks and pedestrian signal heads at all signalized intersections surrounding the project site, with the exception of several corners ofthe Shoreline Boulevard and Terra Bella Avenue intersection. Based on the City' s PQOS map, Terra Bella Avenue, San Rafael Avenue, Linda Vista Avenue, and Middlefield Road and Shoreline Boulevard have a PQOS score of 3 or more, and the project would add pedestrian demand to these roadways. However, as discussed in Section 3. 0, the project would reconstruct and widen the project frontages on Terra Bella Avenue, Linda Vista Avenue, and San Rafael Avenue to include planter strips and new streetlights to create a more walkable pedestrian space adjacent to the proj ect site. Crosswalks would be striped at all four sides of the intersection of Terra Bella Avenue and San Rafael Avenue, and curb ramps would be reconstructed at the intersection as necessary. These improvements would increase pedestrian comfort and safety while improving the pedestrian quality of service and be consistent with the City' s Comprehensive Modal Plan and General Policy LUD 8. 5 by ensuring that roadway improvements address the needs of pedestrians. For these reasons, the project would not conflict with a program, plan, ordinance, or policy addressing the pedestrian circulation system. ( Less than Significant Impact)
Impact TRN- 2: The project would not conflict or be inconsistent with CEQA Guidelines Section 15064. 3, subdivision ( b). ( Less than Significant Impact) As discussed in Section 4. 17. 1. 1 and Impact TRN- 1, the City' s VMT policy includes screening criteria for projects which are presumed to have a less than significant transportation impact. The project would construct 108, 100 percent affordable residential units ( excluding manager' s units) and two storage facility buildings totaling of 408, 964 square feet. Under the City' s VMT policy, projects with 100 percent affordable housing are presumed to result in less than significant transportation impacts.

Therefore, the residential portion of the project would not be required to complete a detailed VMT analysis.

The City' s VMT policy does not provide any specific screening criteria for storage facility projects; however, the City has a methodology for evaluating the VMT of this type of use, which assumes that demand for storage facilities is constant, and the addition of a new (or redeveloping) self -storage site would redistribute existing personal storage -based trips within the City instead of creating new trips.

Ifthe project trip length is less than the average personal storage trip length for this type of use, then the project is considered to have a less than significant VMT impact.

There are 13 personal storage facilities in the City and, are on average, 2. 1 miles to the City' s geographic center. The proposed storage facility would be approximately 1. 4 miles to the City' s geographic center. Therefore, it is concluded that the proposed project would reduce the average distance traveled for this type of development and would result in a less than significant VMT impact.

Based on the discussion above, the project would comply with the City' s VMT policy, consistent with the requirements of CEQA Guidelines Section 15064. 3, subdivision ( b). ( Less than Significant Impact)

Impact TRN- 3: The project would not substantially increase hazards due to a geometric design feature ( e. g., sharp curves or dangerous intersections) or incompatible uses e. g., farm equipment). ( Less than Significant Impact) Site Access
The driveway to the residential parking garage on Terra Bella Avenue would be approximately 22 feet wide, and the driveway on San Rafael Avenue would be approximately 20 feet wide. Both driveway widths meet the required width of 18 feet for a two- way driveway, as described in the City of Mountain View' s Zoning Ordinance. To ensure adequate sight distance for vehicles entering and exiting the residential driveways, it is recommended that 25 feet of red curb be painted on both sides of the driveways along Terra Bella Avenue and San Rafael Avenue to prohibit on -street parking. Both driveways to the storage facility buildings would be 26 feet wide, which would meet the requirement of 18 feet for two- way driveways. To ensure adequate sight distance for vehicles entering and exiting the two driveways, it is recommended that the entire cul- de- sac on Linda Vista Avenue be painted with red curb and that the western half of the San Rafael Avenue cul- de- sac be painted with red curb.

Conditions of Approval
COA TRN- 3. 1: The project would implement the following measures:

Paint 25 feet of red curb on both sides of the driveways along Terra Bella Avenue and San Rafael Avenue to prohibit street parking Paint the cul- de- sac on Linda Vista Avenue and the western half of the San Rafael Avenue cul- de- sac with red curb
Implementing these conditions of approval would increase the level of visibility that motorists would have while approaching or exiting the driveway, which would limit conflicts vehicles, pedestrians, and bicyclists.

Based on the number of projected trips generated by both portions of the project and the relatively low traffic volume on surrounding streets, significant operational issues related to vehicle queueing and vehicle delay are not expected to occur at any of the four driveways on -site. The driveways would operate acceptably and not introduce any significant hazards. 91 In addition, the project would not construct any geometric design changes to the existing streets surrounding the site.

Intersection Queuing
The project would add additional turning vehicles at the intersection of Shoreline Boulevard and Terra Bella Avenue and contribute to the insufficient storage for the southbound left -turn movement during the AM peak hour. However, the proposed residential TDM plan is estimated to reduce the residential vehicle trips by 15 percent. With this reduction, the project is estimated to add 10 vehicles during the AM peak hour to the southbound left -turn movement and would not extend the 95th percentile AM peak hour queue under background conditions and would not have a noticeable effect on traffic operations at this intersection or cause unsafe traffic conditions. 91 Hexagon Transportation Consultants, Inc. 1020- 1040 Terra Bella Avenue Transportation Analysis.

Resolution No. 18773

Land Use Compatibility
Although the development surrounding the project site consists primarily of office and industrial uses, there are already storage facilities on -site and there are residential land uses approximately 700 feet south ofthe project site. Furthermore, as discussed in Section 4. 3 Air Quality and Section 4. 13 Noise, there is a residential development project west ofthe project site that is under construction. The project, therefore, does not propose a use that is incompatible with the existing mix of uses in the project area or propose a use that would bring unusual equipment on the roadways ( e. g., farm equipment). For this reason, the project would not result in a significant impact due to incompatible uses. ( Less than Significant Impact)
Impact TRN- 4: The project would not result in inadequate emergency access. ( Less than Significant Impact)
Access to the prcj ect site for emergency vehicles would be provided via the new two- way driveways.

The project site would be reviewed by the NWFD and be required to meet the standards set forth by the City' s fire code to ensure the project includes the appropriate fire building safety design features and adequate emergency access. As a result, the project would not result in inadequate emergency access. ( Less than Significant Impact)

State
Assembly Bill 52
AB 52, effective July 2015, established a new category of resources for consideration by public agencies called Tribal Cultural Resources ( TCRs). AB 52 requires lead agencies to provide notice of projects to tribes that are traditionally and culturally affiliated with the geographic area if they have requested to be notified. Where a project may have a significant impact on a TCR, consultation is required until the parties agree to measures to mitigate or avoid a significant effect on a TCR or until it is concluded that mutual agreement cannot be reached.

Under AB 52, TCRs are defined as follows:

Sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe that are also either:
o Included or determined to be eligible for inclusion in the California Register of Historic Resources, or
o Included in a local register of historical resources as defined in Public Resources Code Section 5020. 1( k).

A resource determined by the lead agency to be a TCR.

4. 18. 1. 2 Existing Conditions
As discussed in Section 4. 5 Cultural Resources, based on a site -specific records search and literature review, there are no known archaeological sites on -site. However, the record search found a single Native American resource within one- half mile of the project site, which was located approximately

0. 4- mile east of the site. The NAHC was contacted on May 18, 2022, per AB 52, to initiate tribal consultation and a Sacred Lands File search. On June 27, 2022, the NAHC responded and determined the results of the search were positive, and provided a list of nine Native American organizations to reach out to for additional information. These organizations were contacted on July 8, 2022 and the AB 52 30- day consultation window ended on August 7, 2022. No responses to initiate tribal consultation have been received to date.

The project would implement mitigation measure NM CUL- 2. 1, identified in Section 4. 5 Cultural Resources, to reduce the potential for adverse impacts to buried cultural resources ( including TCRs) to a less than significant level. The mitigation measure would provide cultural sensitivity training to educate all contractors on types of artifacts and features that may be encountered and what to do if those items are encountered. In addition, the project would implement the City standard condition of approval ( COA CUL- 2. 1) identified in Section 4. 5 Cultural Resources that would ensure that any objects encountered during ground -disturbing activities are appropriately evaluated for cultural significance and protected if significant, and if human remains are found, determine ifthe remains are Native American.

State
State Water Code
Pursuant to the State Water Code, water suppliers providing water for municipal purposes to more than 3, 000 customers or supplying more than 3, 000 acre- feet ( approximately 980 million gallons) of water annually must prepare and adopt an urban water management plan ( UWMP) and update it every five years. As part of a UWMP, water agencies are required to evaluate and describe their water resource supplies and projected needs over a 20- year planning horizon, water conservation, water service reliability, water recycling, opportunities for water transfers, and contingency plans for drought events.

The City of Mountain View adopted its most recent UWMP in June 2021.

Assembly Bill 939
The California Integrated Waste Management Act of 1989, or AB 939, established the Integrated Waste Management Board, required the implementation of integrated waste management plans, and mandated that local jurisdictions divert at least 50 percent of solid waste generated ( from 1990 levels), beginning January 1, 2000, and divert at least 75 percent by 2010. Projects that would have an adverse effect on waste diversion goals are required to include waste diversion mitigation measures.

Assembly Bill 341
AB 341 sets forth the requirements of the statewide mandatory commercial recycling program.

Businesses that generate four or more cubic yards of garbage per week and multi -family dwellings with five or more units in California are required to recycle. AB 341 sets a statewide goal for 75 percent disposal reduction by the year 2020.

Senate Bill 610
SB 610 amended state law, effective January 1, 2002, to improve the link between information on water supply availability and certain land use decisions made by cities and counties. SB 610 requires preparation of a WSA containing detailed information regarding water availability to be provided to the decision -makers prior to approval of specified large development projects that also require a General Plan Amendment. This WSA must be included in the administrative record that serves as the evidentiary basis for an approval action by the city or county on such projects. Under SB 610, WSAs must be furnished to local governments for inclusion in any environmental documentation for certain projects subject to CEQA.

The ordinance requires all residents and businesses to separate organics out of the trash. 93

4. 19. 1. 2 Existing Conditions
Water Supply and Demand
The City of Mountain View provides water service to the project site. The City is the water retailer for the area and purchases water from two wholesale water suppliers, the SFPUC and Valley Water. In 2020, the City' s water supply production was 84 percent SFPUC, 10 percent Valley Water, two percent groundwater, and four percent recycled water. As of 2020, the City' s existing water supply is 10, 456 acre- feet per year ( AFY) and the City' s water demand is 9, 856 AFY. 94 When accounting for recent updates to the plumbing code, the UWMP has a projected citywide water demand of 12, 058 AFY in 2025 and 14, 163 AFY in 2045. 95
The project site is currently developed with 18 storage facility buildings ( including an on -site rental office) and one dilapidated, uninhabitable residence. These land uses combined have an estimated water demand of approximately 3, 980 gallons per day ( gpd). Water is supplied to the project site by existing 12- inch water mains in Terra Bella Avenue and San Rafael Avenue and an eight -inch water main in Linda Vista Avenue.

Water System
Water Storage
The State Water Resources Control Board Division of Drinking Water ( DDW) requires cities to store enough water to meet eight hours of Maximum Day Demand ( MDD) in addition to four hours of fire flow volume. In order to meet DDW requirements for existing development in the City, the City must have storage capacity for 13. 67 million gallons ( mg) of water. The City' s maximum water storage capacity is approximately 17 mg; however, the City currently operates with only the operational active storage of 14. 3 mg which provides sufficient storage capacity for current needs.

Hydraulic Conveyance
The water system must meet minimum allowable pressure levels under two scenarios, Maximum Day Demand with Fire Flow (MDD+FF) and Peak Hour Demand (PHD). The minimum allowable pressure for the PHD scenario is 40 pound -force per square inch ( psi) and the minimum allowable pressure for the MDD+FF scenario is 20 psi. Mountain View is split into three different pressure zones, and the project site is located in Pressure Zone 1. Under existing conditions, the pressure citywide ( i.e., in all three pressure zones) under the PHD scenario meets the performance criteria of 40 psi. 93 City of Mountain View.

Terra Bella Public Storage & ALTA Housing Project 172 Initial Study City of Mountain View November 2022
Resolution No. 18773

Fire Flow
Based on existing conditions, the fire flow rate required for the project site is approximately 3, 500 gallons per minute ( gpm). This demand is adequately served by the existing fire flow nodes in the area, which can provide maximum flow rates ranging from 3, 747 gpm to 6, 761 gpm. There are several nodes within Pressure Zone 1 with existing deficiencies that do not meet the required flow rate; however, these are not near the project site.

Wastewater Treatment and Sanitary Sewer System
Wastewater Treatment
The City of Mountain View maintains its own wastewater collection system. Sanitary drains in the City are operated and maintained by the Wastewater Section of the Public Works Department. The City pumps its wastewater to the Palo Alto Regional Water Quality Control Plant ( PARWQCP) for treatment. The PARWQCP has an overall 40 million gallons per day ( mgd) average annual treatment capacity. The City has an average annual flow treatment allocation of 15. 1 mgd at the PARWQCP. In 2020, approximately 6. 9 mgd of wastewater from Mountain View was collected and treated by the PARWQCP. 96
Sanitary Sewer System
The existing buildings on -site are estimated to generate approximately 353, 320 gallons of wastewater per year, or 968 gpd. The proj ect site is served by an eight -inch sewer main in Linda Vista Avenue and a 15- inch sewer main in Terra Bella Avenue.

The performance criteria of the sanitary sewer system is calculated by dividing the maximum flow depth ofthe sewage by the diameter ofthe pipe ( d/D). Based on the City' s standard design guidelines, for pipes with a diameter equal to or less than 12 inches, a d/D performance criteria ratio of 0. 50 or less is considered adequate, and any ratio higher than that would be considered deficient. Pipes with a diameter greater than 12 inches would have to meet a d/D performance criteria ratio of 0. 75 or lower to be considered adequate, and any ratio higher than that would be considered deficient.

The sewer system meets the City' s d/D performance criteria along the project flow path. There are no pipes along the flow path that are at risk of surcharging. The system meets d/D performance criteria in all pipes downstream of the project site.

Stormwater Drainage
The storm drainage system that serves the proj ect site is owned and maintained by the City ofMountain View. The project site is currently developed with 18 storage facility buildings and one dilapidated, uninhabitable residence, surface parking lots, and landscaping. The current project site consists of approximately 4. 54 acres ( or 95 percent) of impervious area, including the rooftops of the existing buildings and surface parking areas. The remaining 0. 26 acre ( or five percent) of the site consists of pervious area, which is comprised of landscaping and other permeable surfaces. Stormwater runoff from the project site is collected by a municipal storm drain system consisting of storm drain inlets, 96 Ibid. P. 31.

Terra Bella Public Storage & ALTA Housing Project 173 Initial Study City of Mountain View November 2022
Resolution No. 18773

conveyance pipes, culverts, channels and retention basins operated by the City of Mountain View Public Works Department. Drainage into the City system generally flows north towards the San Francisco Bay. The project site is served by an existing 21- inch storm sewer line in Terra Bella Avenue, 15- inch storm sewer line in Linda Vista Avenue, and 18- inch storm sewer line in San Rafael Avenue.

Solid Waste
Solid waste collection and recycling services for residents and businesses in Mountain View are provided by Recology Mountain View. Once collected, solid waste and recyclables are transported to the SMaRT Station® in Sunnyvale for sorting, and commercial compostable are transported to a composting facility in Vernalis, California. Non -recyclable waste is transported and landfilled at Kirby Canyon Sanitary Landfill in south San Josh. Kirby Canyon Landfill has an estimated remaining capacity of approximately 14. 6 million tons, and a closing date of approximately January 1, 2071. 97 It is estimated that the uses on -site generate approximately 74. 03 tons of solid waste per year. 98 Electric Power and Telecommunications Systems
The project site is served by existing phone and electrical services. Phone service is provided to the site by AT& T, and electrical service is provided by SVCE and delivered over PG& E' s existing utility lines. The site is served by existing electrical vaults on the western border of the site and on northeastern border of the site, in addition to an electric main in Linda Vista Avenue.

( Less than Significant Impact)
Water Supply and Demand
Water supply is analyzed cumulatively based on the buildout of the General Plan and implementation of recommended Capital Improvement Projects ( CIPs). The Average Daily Demand ( ADD) under future cumulative conditions ( 2030 General Plan buildout) is estimated to be approximately 18. 01 mgd.

According to the Utility Impact Study conducted for this project, the project demand for potable water on -site under future cumulative conditions would increase from approximately 5, 370 to 35, 438 gpd, which results in a net increase of 30, 068 gpd ( approximately 0. 0299 mgd). The storage facility would make up 24, 638 gpd ( approximately 70 percent) of the water demand and the residential building would make up 10, 800 gpd ( approximately 30 percent) ofthe water demand. The project' s net increase in water demand would account for 0. 16 percent of the citywide ADD. This incremental increase in demand for water would not substantially impact the City' s ability to meet total system demand. The post project demand under PHD would be 50. 25 mgd and the total supply available to the City under PHD is projected to be 52. 19 mgd, which is adequate to meet the demand from buildout ofthe General Plan and the project. For these reasons, no improvements to or expansion of existing water supply infrastructure is required to serve the proposed project. ( Less than Significant Impact) Water System
Water Storage
The proposed project' s impact on the utility system for water storage was analyzed under cumulative conditions. The cumulative condition scenario incorporates the projected buildout under the 2030 General Plan and recommended CIPs. As discussed in Section 4. 19. 1. 2, the City must maintain a Terra Bella Public Storage & ALTA Housing Project 175 Initial Study City of Mountain View November 2022
Resolution No. 18773

storage capacity of 13. 67 mg of water. The City' s maximum water storage capacity is approximately 17 mg; however, the City currently operates with only the operational active storage of 14. 3 mg which provides sufficient storage capacity for current needs. Post -project, the citywide total for eight hours of MDD would remain the same at 13. 67 mg. Since there is no increase in the DDW requirement, implementation of the project would not require any additional increases in storage capacity, as the City' s infrastructure is capable of storing 14. 3 mg. Therefore, the project would have a less than significant impact on water storage infrastructure. ( Less than Significant Impact) Hydraulic Convey
The proposed project' s impact on the utility system for hydraulic conveyance was analyzed under existing conditions and cumulative conditions. The existing conditions scenario models the project' s impact on the existing condition and configuration of the utility system. The cumulative condition scenario incorporates the projected 2030 General Plan buildout ofthe City, including the recommended CIPs and other recommended upgrades that have been previously identified. As discussed in Section

4. 19. 1. 2, the water system must meet minimum allowable pressure levels under two scenarios, 1VIDD+ FF and PHD. The minimum allowable pressure for the PHD scenario is 40 psi and the minimum allowable pressure for the 1VIDD+ FF scenario is 20 psi.

Under existing conditions, the performance criteria under the PHD scenario is met system -wide in both the pre- and post -project scenarios. Under future cumulative conditions, the analysis in the Utility Impact Study found that the system would continue to maintain an adequate pressure level with the exception of several nodes by Shoreline Golf Links that are just under the performance criteria of 40 psi, but not below 37 psi; however, no new deficiencies result from the project. The analysis in the Utility Impact Study found that despite this slight shortfall in performance criteria in both pre- and post -project scenarios, the system would still maintain adequate pressures. 99 Based on this analysis, the project would have a less than significant impact on pressure levels within the system. ( Less than Significant Impact)
Fire Flow
The proposed project' s impact on the utility system for fire flow was analyzed under existing conditions and cumulative conditions. The existing conditions scenario models the project' s impact on the existing condition and configuration of the utility system. The cumulative condition scenario incorporates the projected 2030 General Plan buildout of the City, including the recommended CIPs and other recommended upgrades that have been previously identified.

Under existing conditions, the planning -level required flow rate is 3, 500 gpm in both pre- and post - project scenarios. Based on the analysis in the Utility Impact Study, the hydrant locations at the proj ect site would continue to maintain adequate fire flow under existing conditions in both pre- and post - project scenarios. Post- proj ect, the available flow rate from these hydrants would decrease slightly to provide a flow rate ranging from 3, 736 gpm to 6, 712 gpm, which would continue to meet the required rate of 3, 500 gpm. As discussed in Section 4. 19. 1. 2, there are several nodes within Pressure Zone 1 with existing deficiencies that do not meet the required flow rate; however, these are not near the 99 Schaaf & Wheeler. 1020 and 1040 Terra Bella & 1055 San Leandro Avenue Utility Impact Study.

project site. Implementation of the project would result in a slight decrease in available fire flow at these deficient nodes; however, the decrease would be less than one percent and is not considered significant."'
Under future cumulative conditions, the required planning -level fire flow rate would be 3, 500 gpm for both pre- and post -project scenarios. Based on the analysis in the Utility Impact Study, two ofthe three hydrant locations at the project site provide an adequate fire flow rate and one is considered deficient as its pre -project available flow is limited to 3, 330 gpm, which is below the required flow rate of 3, 500 gpm. Implementation ofthe project would result in an incremental increase in this existing deficiency, as the post -project available flow rate would decrease to 3, 319 gpm. The increase in water demand would result in less than a one percent decrease in available fire flow at the nearest deficient nodes; therefore, the impact is not considered significant. In addition, although the fire flow rate at this hydrant would not meet the required planning level flow rate of 3, 500, the prof ect would install fire sprinklers in all three buildings which would be consistent with California Fire Code ( CFC) Section B 105. 2. The installation of these automatic fire sprinklers in each building would reduce the project -specific fire flow rate requirement to 1, 500 gpm, which would be met by all three fire hydrants at the project site. 101 Based on this discussion, the project would have a less than significant impact on required fire flow rates at the project site. ( Less than Significant Impact) Sanitary Sewer Infrastructure
The project site is served by an eight -inch sewer main in Linda Vista Avenue and a 15- inch sewer main in Terra Bella Avenue. The residential portion of the proposed project would construct new domestic sanitary sewer lateral connections to the existing sanitary sewer main in Terra Bella Avenue. The storage facility portion of the project would construct new sanitary sewer lateral connections to the existing sanitary sewer main in Linda Vista Avenue. Under existing plus project conditions, the estimated sewer flow would be 26, 579 gpd ( 18, 479 for the storage facility and 8, 100 gpd for the residential building), which is an increase of 25, 611 gpd compared to the existing sewer flow on -site of 968 gpd. The storage facility would make up 18, 479 gpd ( approximately 69. 5 percent) ofthe sewer flow and the residential building would make up 8, 100 gpd ( approximately 30. 5 percent) ofthe sewer flow.

Existing Plus Project Impacts
Under existing conditions, the sewer system would meet the City' s d/D performance criteria along the project flow path in both pre- and post -project scenarios. There would be no pipes with deficiencies downstream ofthe project site under either scenario.

Cumulative Plus Project Impacts
The future cumulative condition assumes that the CIPs recommended as part ofthe 2030 General Plan Update Utility Impact Study ( GPUUIS) are constructed. Four of the recommended CIPs from the GPUUIS are located downstream of the project site. The model also accounts for the buildout of the 2030 General Plan and other additional projects that are currently under review, under construction, approved, or recently completed as of June 2022.

Resolution No. 18773

Under these future cumulative conditions, the sewer system downstream ofthe project site would meet the City' s d/D performance criteria along the project flow path in both pre- and post -prof ect scenarios.

There would be no new deficiencies downstream of the project site due to the projects incremental increase in sewer flow under either scenario.

City policy requires that a proj ect' s contribution to recommended CIPs be calculated to determine the fair share fee required from developers to assist in the implementation of the CIP. The City has determined that contributions of less than one percent fall within the margin of error for variability within the model. Therefore, only projects that contribute more than one percent would be responsible for the fair share fee associated with the CIP. Of the four GPUUIS recommended CIPs downstream of the project site, the storage facility would result in a contribution of more than one percent to CIP 9P100 at 13 pipe segments, ranging from 1. 04 to 1. 07 percent. The residential building would result in a contribution under one percent to CIP 9P- 100, ranging from 0. 38 to 0. 47 percent. The storage facility applicant would be required to pay the appropriate fair share fee prior to redevelopment of the project site given the storage facility' s contribution of more than one percent. The fees would be used by the City to fund the identified CIP and reduce the project' s impact to the sanitary sewer system to a less than significant level. The Future CIPs required within the City would be subject to a separate project specific environmental review at the time the design and construction details of the CIPs are known.

Mitigation measures for construction -related impacts ( such as the ones discussed in this Initial Study) typically reduce construction -related impacts to a less than significant level. ( Less than Significant Impact)
Stormwater Drainage Infrastructure
The project site is currently comprised of 4. 54 acres ( or approximately 95 percent) ofimpervious area, and 0. 26 acre ( or approximately five percent) of pervious area. The proposed project would reduce the amount of impervious surface to 3. 89 acres ( or 81 percent). The project would replace portions of the project site that are currently impervious with improvements such as bioretention areas, landscaping, and rain gardens. These improvements would result in a reduction of impervious surface would result in a corresponding decrease the amount of runoff from the project site. Runoff from the project site currently flows into an existing 21- inch storm drain line in Terra Bella Avenue, 15- inch storm drain line in Linda Vista Avenue, and 18- inch storm drain line in San Rafael Avenue.

Both the residential and storage facility portions of the project would construct new storm drain inlets on -site and make lateral connections to the existing storm drain lines in Terra Bella Avenue, Linda Vista Avenue, and San Rafael Avenue. The storm drain improvements needed in order to convey stormwater to the existing storm drain lines would require trenching during construction. Construction related impacts from trenching for the storm drain improvements would be less than significant. ( Less than Significant Impact)
Electric Power and Telecommunications Facilities
Existing electricity and telecommunications utility infrastructure currently serve the project site and would continue to serve the site under the proposed project. The project would be 100 percent electric and no new natural gas connections are proposed. Electric lines for the residential portion ofthe project would connect to an existing electrical vault on San Rafael Avenue northeast ofthe proposed building, Terra Bella Public Storage & ALTA Housing Project 178 Initial Study City of Mountain View November 2022
Resolution No. 18773

and overhead electricity lines along the project frontage on Terra Bella Avenue would remain in place.

The storage facility portion ofthe project would install electric lines and transformers on -site to connect to the existing electric main in Linda Vista Avenue. The work would be completed within the boundaries of the project area, limiting the impact on the public right- of-way. Construction - related impacts from these improvements are less than significant. ( Less than Significant Impact) Impact UTL- 2: The project would have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years. ( Less than Significant Impact)
The current water demand at the project site is estimated to be approximately 5, 370 gpd based on the existing land uses and densities. That demand would increase by 30, 068 net gpd for a total of 35, 438 gpd after the project is completed. The proposed residential building would achieve GreenPoint Rated Gold certification level, in part, by installing drought tolerant landscaping with high -efficiency irrigation and water efficient interior fixtures to further reduce the demand for water on -site. The storage facility buildings would have a limited number of water fixtures given the use ofthe buildings; however, the two buildings would also install water efficient interior fixtures and high -efficiency irrigation for the drought tolerant landscaping around the perimeter of the site.

As of 2020, the City' s existing water supply is 10, 456 acre- feet per year ( AFY) and the City' s water demand is 9, 856 AFY. 102 The project' s estimated net increase in water demand compared to existing conditions of 30, 068 gpd ( approximately 33. 7 AFY) would account for approximately 0. 3 percent of the overall water supply in the city. The project would result in an incremental increase in demand for water in the city; however, Mountain View would maintain sufficient supply to accommodate the small increase in demand during normal years. As discussed in Section 4. 19. 1. 2, the City' s 2020 UWMP found that the City had adequate water supplies to meet demand through 2045 in normal years, with potential shortfalls up to 20 percent due to cuts in supply from SFPUC in dry years. 103
To maintain adequate water supply during dry and multiple dry years where there may be shortfalls in supply, the City would institute mandatory conservation measures, with escalating levels of conservation requirements as the shortages in water supply increase. These measures include limiting outdoor water use, encouraging further conservation through outreach programs, and requiring the rapid repair of leaks. The entire City, including the proposed project, would be subject to these measures during dry and multiple dry years. Compliance with mandatory conservation measures in the City would ensure that sufficient water supply in maintained in normal, dry, and multiple dry years.

Impact UTL- 3: The project would not result in a determination by the wastewater treatment provider which serves or may serve the project that it does not have adequate capacity to serve the project' s projected demand in addition to the provider' s existing commitments. ( Less than Significant Impact)
Existing Plus Project Impacts
As discussed in Section 4. 19. 1. 2, the PARWQCP treats wastewater from the City and has an overall average annual treatment capacity of 40 mgd. The City has an average annual flow treatment allocation of 15. 1 mgd at the PARWQCP. In 2020, approximately 6. 9 mgd of wastewater from Mountain View was sent to the PARWQCP for treatment.104 This results in an available capacity of approximately 8. 2 mgd of available treatment capacity for the City at the PARWQCP. As discussed under Impact UTL1, the project would generate approximately 25, 611 gpd ( 0. 026 mgd) more than the current development on -site under existing conditions. Based on this information, the PARWQCP would have adequate capacity to treat the existing demand in addition to the increase in wastewater resulting from the proposed project. ( Less than Significant Impact)
Cumulative Plus Project Impacts
Under future cumulative conditions, it is estimated that the City would generate approximately 14. 15 mgd of wastewater in the pre -project scenario, which would account for approximately 93. 7 percent of the capacity available to the City at the PARWQCP. In the post -project scenario, that total would increase to 14. 176 mgd ( approximately 93. 88 ofthe capacity available to the City), which is an increase of approximately 0. 026 mgd contributed by the project. Under the Basic Agreement between the City, Palo Alto, and Los Altos, an engineering study to redefine the anticipated future needs ofthe treatment plant is required once each respective service area reaches 80 percent of their contractual capacity rights. Based on this agreement, the City would be required to conduct this engineering study once the average annual flow to the PARWQCP increases to 12. 08 mgd during the buildout ofthe General Plan.

Any recommendations regarding physical improvements to the PARWQCP resulting from this engineering study would be subject to separate environmental review. Although the project would contribute to the increased generation of wastewater associated with the bwldout of the General Plan, it would only account for less than a quarter of one percent of the overall capacity need in the City.

Based on this discussion, the project' s contribution would considered less than significant. ( Less than Significant Impact)
Impact UTL- 4: The project would not generate solid waste in excess of state or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals. ( Less than Significant Impact) In compliance with CALGreen requirements, the project would be required to recycle and/or salvage for reuse a minimum of 65 percent ofthe nonhazardous construction and demolition debris resulting from construction activities. The proposed project would limit the amount of operational waste disposed of through the provision of on -site recycling collection, as required by AB 341. 104 Ibid. Page 31.

Terra Bella Public Storage & ALTA Housing Project 180 Initial Study City of Mountain View November 2022
Resolution No. 18773

As discussed in Section 4. 19. 1. 2, the existing improvements on -site produce approximately 74. 03 tons of solid waste per year. Once operational, the project would generate an additional 360. 53 tons of solid waste compared to existing conditions, for an annual total of approximately 434. 56 tons. Solid waste generated by the project would be sorted at the SMaRT Station® in Sunnyvale, and any non -recyclable waste would be transported to Kirby Canyon Landfill, which has an estimated remaining capacity of approximately 14. 6 million tons and a closing date of approximately January 1, 2071. Based on the remaining capacity at Kirby Canyon Landfill and the estimated amount of waste generated by the project, the landfill would have sufficient capacity to serve the project.

Because the project can be served by a landfill with capacity and would be required to comply with existing local and state programs and regulations, the project' s impacts related to solid waste and landfill capacity and attainment of solid reduction goals would be less than significant. ( Less than Significant Impact)
Impact UTL- 5: The project would be compliant with federal, state, or local management and reduction statutes and regulations related to solid waste. ( Less than Significant Impact)
As discussed under Impact UTL- 4, the proposed project would comply with state and local regulations related to solid waste reduction. The project would comply with CALGreen standards for construction waste recycling and divert at least 65 percent of construction waste resulting from construction activities on -site. The proposed project would comply with AB 341 by utilizing the City' s garbage service, which commercially sorts recyclable material at the SMaRT Station®. In addition, the residential portion ofthe project would comply with SB 1383 and City Code by offering compost bins in the on -site trash collection rooms that residents could utilize to dispose of their organic waste ( i.e., food scraps). Furthermore, solid waste from the project site would be disposed of at the Kirby Canyon Landfill in San Josh, as discussed under Impact UTL- 4. The project would not result in a substantial increase in waste landfilled at Kirby Canyon, nor would it be served by a landfill without sufficient capacity. In compliance with the City Code and General Plan policies, the project would not conflict with state and federal solid waste regulations and statutes.

As discussed in Section 4. 0 of this Initial Study, the proposed project would not degrade the quality of the environment with implementation of City standard conditions of approval and the identified mitigation measures. As discussed in Section 4. 4 Biological Resources, the project would not impact sensitive habitats or special -status species. The project would implement City standard condition of approval COA 13I0- 1. 1 to reduce impacts to nesting birds to a less than significant level.

Impact MFS- 2: The project does not have impacts that are individually limited, but cumulatively considerable. ( Less than Significant Impact with Mitigation Incorporated)
Under Section 15065( a)( 3) of the CEQA Guidelines, a lead agency shall find that a project may have a significant effect on the environment where there is substantial evidence that the project has potential environmental effects " that are individually limited, but cumulatively considerable." As defined in Section 15065( a)( 3) ofthe CEQA Guidelines, cumulatively considerable means " that the incremental effects of an individual project are significant when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects." As discussed in Sections 4. 2, 4. 12, and 4. 20, the project would not impact agricultural or forestry resources, mineral resources, or wildfire. Therefore, the project would not contribute to a cumulative impact to these resources.

In general, an individual project' s impact on broader resources including air quality, energy, GHGs, and VW are evaluated at a cumulative level. That is, if a project results in a significant impact to air quality ( specifically criteria air pollutants), energy, GHGs, and VMT, the project would be considered to have a significant cumulative impact to those resources. As discussed in Sections 4. 3, 4. 6, 4. 8, and

4. 17, the project would not result in significant ( individual and cumulative) impacts to those resource areas with the implementation of the identified City standard conditions of approval ( COA AIR- 1. 1 and AIR- 3. 1) and mitigation measure ( NM AIR- 1. 1). Cumulative health risk impacts are discussed in Section 4. 3. 2 and found to be less than significant with the implementation of City standard condition of approval COA AIR- 1. 1 and mitigation measure MM AIR- 1. 1. Cumulative utility impacts are discussed in Section 4. 19. 2and found to be less than significant with the implementation of planned CIPs.

The project' s impacts to cultural resources and TCRs are specific to the site, and as discussed in Sections 4. 5 and 4. 18, implementation of mitigation measure MM CUL- 2. 1 and City standard condition of approval COA CUL- 2. 1 would reduce those impacts to a less than significant level.

The geographic area for cumulative aesthetic, cultural resources ( including TCRs). geology and soils, hazards and hazardous materials, and noise impacts is generally the immediate vicinity of the project site because it would affect common resources and impacts would be limited to the immediate vicinity.

In regard to cumulative aesthetic impacts, there are two cumulative projects in the immediate vicinity of the project: 1) a commercial office project located 1155 & 1185 Terra Bella Avenue that proposes to construct a 20, 000 square foot office building and surface parking lot and 2) a mixed -use project located at 1001 North Shoreline Boulevard that would construct a seven -story, 203- unit apartment building, a seven - story, 100 condominium -unit building, and a six -level parking structure to accommodate the existing office building on -site. These cumulative projects would not result in a significant cumulative aesthetics impact because the cumulative projects are required to undergo the same DRC review process to ensure compliance with General Plan policies and City Code regulations regarding view preservation, minimization of light and glare, and neighborhood compatibility.

Cumulative projects are subject to the same existing state, regional, and local regulations including the MBTA, Fish and Game Code, City Tree Preservation Ordinance, CBC, NW provisions, PCB/ACM/L,BP regulatory screening requirements, NPDES permit requirements, General Plan policies, and City Code regulations identified in Sections 4. 4, 4. 5, 4. 7, 4. 9, 4. 10, and 4. 18. Compliance Terra Bella Public Storage & ALTA Housing Project 184 Initial Study City of Mountain View November 2022
Resolution No. 18773

with these regulations, in addition to implementation of City standard conditions of approval ( such as COAs, BIO- 1. 1, BIO- 5. 1, CUL- 2. 1, GEO- 1. 1, GEO- 6. 1, HAZ- 2. 1, 14AZ- 2. 2, HYD- 1. 1) would ensure significant individual and cumulative biological resources, cultural resources ( including TCRs), geology and soils, hazards and hazardous materials, hydrology and water quality, are reduced to a less than significant level. Cumulative noise impacts are discussed in Section 4. 13. 2 and found to be less than significant.

In addition, except for affordable housing projects, cumulative residential developments are required to pay park land dedication fees required by the City. Cumulative residential projects are also required to pay school impact fees in accordance with California Government Code Section 65996 and comply with General Plan Policy MOB 10. 4, which would ensure adequate emergency response times. For these reasons, cumulative projects would not contribute to a cumulative significant recreation or public services impact.

Land uses in the City are regulated through the General Plan, Zoning Ordinance, and depending on the location ofthe site, the Moffett Federal Airfield CLUP. The project requires a General Plan amendment and rezoning to allow for construction of residential uses on -site. As discussed in Section 4. 11, the prof ect would comply with the Moffett Federal Airfield CLUP by implementing condition of approval COA 14AZ- 5. 1 and notifying the FAA if any construction equipment on -site would exceed 146 feet in height.

As discussed in Section 4. 14, the proposed project would result in up to 109 residential units ( and approximately 256 new residents) that were not accounted for the in the 2030 General Plan buildout.

The project' s number of residential units and estimated residents represents a 0. 2 percent increase in population compared to the General Plan buildout. Given this incremental increase and the projected City growth, the project would not result in a significant cumulative population and housing impact.

As discussed in Section 4. 19. 2, a cumulative utility analysis was conducted to evaluate the potential impacts of the proposed project on the water and sanitary sewer system in the City. This cumulative analysis determined that the project would have a less than significant impact on the water and sanitary sewer system under future cumulative conditions. Future cumulative projects would be required to confirm sufficient water supply, wastewater treatment capacity, and solid waste disposal capacity. In addition, cumulative projects would detail the exact locations for all utility connections and utility plans as part of the design review process. Therefore, cumulative projects would not result in a significant cumulative utility and service impact.

Given the above considerations, the proposed project would not result in a cumulatively considerable contribution to a significant cumulative impact. ( Less than Significant Cumulative Impact with Mitigation Incorporated)
Impact MFS- 3: The project does not have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly. ( Less than Significant Impact with Mitigation Incorporated)
Consistent with Section 15065( a)( 4) of the CEQA Guidelines, a lead agency shall find that a project may have a significant effect on the environment where there is substantial evidence that the project has the potential to cause substantial adverse effects on human beings, either directly or indirectly.

Under this standard, a change to the physical environmental that might otherwise by minor must be treated as significant if it would cause substantial adverse effects to humans, either directly or indirectly. This factor relates to adverse changes to the environment of human beings generally, and not effects on particular individuals.

The potential for the proposed project to result in changes to the environment that could directly or indirectly affect human beings is evaluated in each section of this Initial Study using the CEQA Checklist. In particular, the resource areas that could directly affect human beings include air quality, geology and soils, hazards and hazardous materials, and noise. The potential project -related impacts discussed in Sections 4. 3, 4. 7, 4. 9, 4. 13 would all be reduced to a less than significant level with adherence to existing regulations and implementation ofthe identified mitigation measures ( NM AIR- 1. 1 and NOI-2. 1) and City standard conditions of approval ( COAs AIR- 1. 1, AIR- 1. 2, AIR-5. 1, GEO- 1. 1, 14AZ- 2. 1, HAZ- 2. 2, NOI- 1. 1, NOI- 1. 2, NOI- 2. 1, and NOI-4. 1). No other direct or indirect adverse effects of the project on human beings have been identified. ( Less than Significant Impact with Mitigation Incorporated)

L RESPONSE TO COMMENTS
One comment letter from the Department of Toxic Substances Control dated December 22, 2022 was received by the City during the public review period for the IS/ MND. Responses to the comments are provided below. A copy of the comment letter is provided in Attachment A of this memorandum.

Comment 1: The Department of Toxic Substances Control ( DTSC) received a Mitigated Negative Declaration ( MND) for the Terra Bella Public Storage & ALTA Housing Project ( Project). The Lead Agency is receiving this notice from DTSC because the Project includes one or more ofthe following:
groundbreaking activities, work in close proximity to a roadway, importation of backfill soil, and/or work on or in close proximity to an agricultural or former agricultural site.

Response 1: The comments pertaining to the topics mentioned in the above comment are responded to below.

Comment 2: The MND references the listing compiled in accordance with California Government Code Section 65962. 5, commonly known as the Cortese List. Not all sites impacted by hazardous waste or hazardous materials will be found on the Cortese List. DTSC recommends that the Hazards and Hazardous Materials section of the MND address actions to be taken for any sites impacted by hazardous waste or hazardous materials within the Project area, not just those found on the Cortese List.

Response 2: Section 4. 9. 1. 2 ofthe IS/MND summarizes the site history and hazardous materials contaminations documented in the project area based on Phase I Environmental Site Assessments ( ESAs) completed for the project site. The Phase I ESAs were prepared in accordance with American Society for Testing and Materials ASTM) standard practices and included a search of databases that comprise the Cortese List ( including DTSC' s EnviroStor and the State Water Resources Control Board' s GeoTracker) and other federal, state, tribal, and county regulatory databases.

The other federal, state, tribal, and county regulatory databases searched included the Comprehensive Environmental Response, Compensation and Liability Information System ( CERCLIS), RCRAInfo, Leaking Underground Fuel Tank Reports, Aboveground Storage Tanks, Leaking Underground Storage Tanks on Indian Lands, Underground Storage Tanks on Indian Lands, Santa Clara County — CUPA Facilities List, and Santa Clara County — Local Oversight Program Listing databases. Refer to Appendices E and G of the IS/MND for the names of all databases searched and the results.

Comment 3: DTSC recommends consulting with other agencies that may provide oversight to hazardous waste facilities and sites in order to determine a comprehensive listing of all sites impacted by hazardous waste or hazardous materials within the Project area.

Response 3: The IS/ MND was submitted to the State Clearinghouse, where it was distributed to state agencies including the DTSC, State Water Resources Control Board, and the San Francisco Regional Water Quality Control Board ( Water Board).

The City also provided the Notice of Intent to adopt the IS/ MND to the public, 2 1871 The Alameda, Suite 200 • San Josh, CA 95126 9 Tel: ( 408) 248- 3500 9 Fax: ( 408) 248- 9641 9 www. davidjpowers. com Resolution No. 18773

responsible and trustee agencies, and the Santa Clara County Clerk. The City did not receive comments from other agencies besides DTSC.

Comment 4: DTSC hazardous waste facilities and sites with known or suspected contamination issues can be found on DTSC' s EnviroStor data management system. The EnviroStor Map feature can be used to locate hazardous waste facilities and sites for a county, city, or a specific address. A search within EnviroStor indicates that numerous hazardous waste facilities and sites are present within the Project' s region.

Response 4: As discussed in Response 2 above, the Phase I ESAs completed for the project included a search of DTSC' s EnviroStor database. The Phase I ESAs ( which are included in Appendices E and G of the IS/MND) includes the search results and identified conditions that could affect the project site based on distance, type of contamination, and groundwater gradience. The summary of the Phase I ESA findings is included in Section 4. 9. 1. 2 of the IS/MND.

Comment 5: DTSC recommends that the following issues be evaluated in the Hazards and Hazardous Materials section ofthe MND: 1. A State of California environmental regulatory agency such as DTSC, a Regional Water Quality Control Board ( RWQCB), or a local agency that meets the requirements of Health and Safety Code section 101480 should provide regulatory concurrence that project site is safe for construction and the proposed use.

Response 5: Condition of approval COA HAZ- 8. 1 on pages 105 and 106 of the IS/ MND requires the project applicant work with an oversight agency, which could be the U.S. Environmental Protection Agency ( U.S. EPA), DTSC, SRWQCB, or County of Santa Clara Department of Environmental Health, to address site remediation or building design/ construction requirements. The condition requires the design of remediation equipment, equipment placement, or remediation activities be reviewed by the oversight agency and City. In addition, the condition requires written proof from the regulatory agency be submitted to the City that the remediation and/ or design is adequate. Alternatively, ifit is determined no remediation is required, documentation that no regulatory oversight is needed is required to be submitted to the City.

Comment 6: 2. The MND acknowledges the potential for historic or future activities on or near the Project site to result in the release of hazardous wastes/ substances on the Project site. In instances in which releases have occurred or may occur, further studies should be carried out to delineate the nature and extent ofthe contamination, and the potential threat to public health and/or the environment should be evaluated. The MND should also identify the mechanism( s) to initiate any required investigation and/ or remediation and the government agency who will be responsible for providing appropriate regulatory oversight.

Response 6: Condition of approval COA HAZ- 8. 1 on pages 105 and 106 of the IS/MND requires the project to obtain oversight by the appropriate regulatory agency and conduct any additional studies as required by the oversight agency to further delineate and implement site remediation or building design/ construction requirements to ensure the health and safety of future occupants and the environment. 3 1871 The Alameda, Suite 200 • San Josh, CA 95126 9 Tel: ( 408) 248- 3500 9 Fax: ( 408) 248- 9641 9 www. davidjpowers. com Resolution No. 18773

Comment 7: 3. Refiners in the United States started adding lead compounds to gasoline in the 1920s in order to boost octane levels and improve engine performance. This practice did not officially end until 1992 when lead was banned as a fuel additive in California. Tailpipe emissions from automobiles using leaded gasoline contained lead and resulted in aerially deposited lead ( ADL) being deposited in and along roadways throughout the state. ADL- contaminated soils still exist along roadsides and medians and can also be found underneath some existing road surfaces due to past construction activities. Due to the potential for ADL- contaminated soil, DTSC recommends collecting soil samples for lead analysis prior to performing any intrusive activities for the Project described in the MND.

Response 7: Text has been added to Section 4. 9. 1. 2 ofthe IS/MND to clarify the site' s potential to contain ADL- contaminated soil. Text has also been added to condition of approval COA HAZ- 2. 1 to clarify the potential presence of elevated levels of ADL would be investigated as part of the regulatory oversight review and approval process with documentations submitted to the City prior to issuance of any project permits.

Refer to Section II of this memorandum for the added text.

Comment 8: 4. If any projects initiated as part of the proposed Project require the importation of soil to backfill any excavated areas, proper sampling should be conducted to ensure that the imported soil is free of contamination. DTSC recommends the imported materials be characterized according to DTSC' s 2001 Information Advisory Clean Imported Fill Material.

Response 8: The project does not propose to import soils; therefore, the above reference to the 2001 Information Advisory Clean Imported Fill Material is not applicable.

Comment 9: 5. If any sites included as part of the proposed Project have been used for agricultural, weed abatement or related activities, proper investigation for organochlorinated pesticides should be discussed in the MND. DTSC recommends the current and former agricultural lands be evaluated in accordance with DTSC' s 2008 Interim Guidance for Sampling Agricultural Properties ( Third Revision).

Response 9: As discussed in Section 4. 9. 1. 2 on page 97 and Section 4. 9. 2 on page 100 of the IS/MND, the project site was previously used as agricultural land and on -site soil could be contaminated with agricultural chemicals. Text has been added to condition of approval COA HAZ- 2. 1 ( which requires the preparation of a soil management plan) to clarify that the potential presence of elevated levels of organochlorine pesticide would be investigated as part of the regulatory oversight review and approval process, with documentations submitted to the City prior to issuance of any project permits. DTSC' s 2008 Interim Guidance for Sampling Agricultural Properties ( Third Revision) and any other applicable DTSC guidance documents, would be considered.

been REVISED as follows:

The project site, located along U.S. 101, has historically been used as agricultural land. In 1953 the o, 0s, a single- family residence ( which has since been converted into commercial office space), a detached garage, and a shed were constructed on the 1020 Terra Bella Avenue parcel. The existing storage facility on the 1040 Terra Bella Avenue parcel was constructed by 1974.

Contamination has been ADDED as follows:

California banned lead as a fuel additive in 1992. Due to the site' s proximity to U.S. 101, the on -site soils closet to U.S. 101 may contain aerially deposited lead ( ADL) from automobiles driving along U. S. 101.

Section 4. 14. 1. 2 has been ADDED as follows:

The project site is currently developed with one uninhabitable single -story residence and 77, 418 square feet of commercial space including habitable one manager' s unit, therefore, the existing population on - site is approximately two residences.

Pages 140 and 141 Draft Initial Study; text in the second paragraph under Impact POP- 1 in Section

4. 14. 2 has been REVISED as follows:

The project site currently has a General Plan designation of General Industrial, which does not allow residential development and, therefore, was not projected to accommodate any net population or housing growth at the buildout of the General Plan. The proposed project would construct a 108- unit residential building, and potentially replace the existing an additional unit for the storage facility manager in Building 1 of the proposed storage facility, which would result in 109 units and approximately 2-5.6 254 new residents more than existing conditions and what was assumed in the 2030 General Plan buildout ( approximately 0.2 percent more than assumed from the General Plan buildout) 8o Although the project would result in an incremental increase in population beyond what was anticipated in the General Plan, the 0. 2 percent increase in population would not be a substantial increase in unplanned population.

REVISED as follows:
2022.
80 The population estimate uses the City' s average of 2. 35 persons per household for all of the dwelling units, including the two manager' s units.

Impact POP- 2 in Section 4. 14. 2 have been REVISED as follows:

As discussed in Section 4. 14. 1. 2, there is one are re hattsi„ g „ r4 e habitable manager' s unit es eon- site, which would bereplaced by the project.

ADDED as follows:

The project site is currently developed with 18 storage facility buildings ( including an on -site rental office and a manager' s unit) and one dilapidated, uninhabitable residence. These land uses combined have an estimated water demand of approximately 3, 980 gallons per day ( gpd). The existing water use is based on Darcel- level demand adopted from the Citv' s InfoWater model developed as Dart of the 2010 Water Master Plan. The demand in the model was calibrated af4ainst water billing records from 2005 and 2006_ as explained in the 2010 Water Master Plan ( refer to ADDendix M for additional information about the modeled demand). Water is supplied to the project site by existing 12- inch water mains in Terra Bella Avenue and San Rafael Avenue and an eight -inch water main in Linda Vista Avenue.

Water Supply and Demand in Section 4. 19.2 has been ADDED as follows:

Water supply is analyzed cumulatively based on the buildout of the 2030 General Plan land uses and implementation of recommended Capital Improvement Projects ( CIPs). The Average Daily Demand ADD) under future cumulative conditions ( 2030 General Plan buildout) is estimated to be approximately 18. 01 mgd. According to the Utility Impact Study conducted for this project, theejee demand for potable water on -site under future cumulative conditions ( 2030 General Plan buildout) would be approximately 5, 370 gpd. With implementation of the project, the water demand on -site would increase from approximately 5, 370 to 35, 438 gpd, which results in a net increase of 30, 068 gpd approximately 0. 0299 mgd). Water unit duty factors used to calculate the project' s water use were developed as part of the North Bayshore Precise Plan Phase II from water meter records of recent developments throughout the City. The unit duty factors applied are representative of the proposed uses. The City does not currently have a specific water demand factor for storage buildings, therefore, the City' s closest water demand factor of Industrial was used for calculating the storage facility' s water use, consistent with studies the City coMpleted for other similar projects ( refer to Appendix M for additional information about the methodology used). The storage facility would make up 24, 638 gpd approximately 70 percent) of the water demand and the residential building would make up 10, 800 gpd ( approximately 30 percent) ofthe water demand.

INTRODUCTION AND OVERVIEW
HMH was contracted to complete a survey, assessment and arborist report for trees located within the limit of work illustrated on Exhibit A. The project site encompasses parts of two adjacent parcels, totaling approximately 1 acre. One parcel is currently a Public Storage property and the other currently has a house. The 101 Freeway is to the north of the site and there are primarily commercial parcels to the east, south and west of the site. Our scope of services includes locating, measuring DBH, assessing, and photographing the condition of all trees within the limit of work. Disposition and health recommendations are based on current site conditions. Site development/ design may affect the preservation suitability.

METHODOLOGY
Our tree survey work is a deliberate and systematic methodology for cataloging trees on site:

1. Identify each tree species.

2. Note each tree' s location on a site map.

3. Measure each trunk circumference at 4. 5' above grade per ISA standards.

4. Evaluate the health and structure of each tree using the following numerical standard:
5 - A healthy, vigorous tree, reasonably free of disease, with good structure and form typical of the species. 4 - A tree with slight decline in vigor, small amount of twig dieback, minor structural defects that could be corrected.
3 - A tree with moderate vigor, moderate twig and small branch dieback, thinning of crown, poor leaf color, moderate structural defects that may that might be mitigated with care. 2 - A tree in decline, epicormic growth, extensive dieback of medium to large branches, significant structural defects that cannot be abated.
1 - A tree in severe decline, dieback of scaffold branches and or trunk, mostly epicormic growth, - extensive structural defects that cannot be abated.
0 - Tree is dead.

SU viiilAkY Ut FINDINGS
HMH conducted a tree inventory of 12 trees located within the limit of work outlined in Exhibit A.

Two ( 2) of the trees inventoried are classified as heritage trees under the City of Mountain View Tree Removal permit. The trees were initially evaluated on 2/ 22/2021 and re- evaluated on 12/ 6/ 2022.

A heritage tree is:

Single Trunk - 48 inches or more in circumference at 4 %2 feet above ground; or Multi -trunk - which has major branches below fifty- four ( 54) inches above the natural grade with a circumference of forty-eight (48) inches measured just below the first major trunk fork.; or Any Quercus ( oak), Sequoia ( redwood) or Cedrus ( cedar) with a circumference of 12" measured at 4 %2 feet above natural grade; or
A tree or grove of trees designated as " heritage" by the City Council.

Table 1 - Tree Quantity Summary summarizes tree quantities by both species and size. Each species that was inventoried as part of this scope is included. This is a useful tool for analyzing the mixture of trees as part of the project. The size table is useful when calculating mitigation requirements in the case of tree removal as well as aiding in determining tree maturity.

GENERAL OBSERVATIONS AND RECOMMENDATIONS
For tree removal justification, please see Tree Disposition Plan.

Species: Corymbia ficifolia ( Red Flowering Gum)
Quantity: 2
Tree Number: 6, 8
Observations / Recommendations:

The Red Gum trees are mature specimens and are in good shape and are a significant canopy tree at the front of the Public Storage site. The internal branching structure of these trees could benefit from a structural pruning effort. These trees, as all along the street frontage, are under power lines that could be problematic long term if topping occurs. These trees are not good candidates for transplanting. Tree # 6 is being removed due to site design.

Upon reviewing the civil plan set dated 12/ 12/2022 and the landscape plan set dated 9/22/2022, here are recommendations to consider for retaining Tree # 8 and to lessen the impact of construction:

Follow the City of Mountain View tree protection specifications.

It is best to avoid installing utility lines underneath the dripline of the tree. But it appears a storm drain line will be installed approximately 7- 1/ 2 feet from the trunk. It is important to follow standard best practices such as avoiding mechanical trenching or excavation. The use of an air spade or hand excavation should be done. If root pruning is needed this should be done with a clean cut and the area around the cut should be kept moist until it can be backfilled. If there are roots larger than 2", tunnel underneath with horizontal boring.

Avoid constructing decking/ footings underneath the dripline of the tree There is a new sidewalk approximately almost 6 feet from the trunk. Mechanical trenching and excavation should be avoided. An air spade or hand excavation should be done to for the construction area. If root pruning is needed this should be done with a clean cut and the area around the cut should be kept moist until it can be backfilled.

New plantings underneath the dripline of the tree should match the WUCOLS water use rating, which is low.

It appears the new building will be further from the tree than the existing building. Generally the root structure has probably developed to avoid this area and the new construction will not greatly affect the existing root system. The structural plans should be reviewed by the design team to see the extent of the building' s footings under the dripline of the tree and consider alternatives, if possible.

Resolution No. 18773

Species: Magnolia grandiflora ( Southern Magnolia)
Quantity: 1
Tree Number: 2
Observations / Recommendations:

The Magnolia tree is a younger specimen and is in good to moderate shape. It is located on the east site of the Public Storage site on San Rafael Avenue. Tree number two is under the powerlines which could be an issue long term if topping occurs. As Magnolia are a moderate water use tree ensuring that adequate irrigation is being applies would help the vigor of these trees. This tree is not a good candidate for transplanting. Tree # 2 is being removed due to site design.

Species: Pistacia chinensis ( Chinese Pistache)
Quantity: 5
Tree Number: 3, 4, 9, 10, 11
Observations / Recommendations:

The Pistache trees are younger specimens and are in good shape. These trees, as all along the street frontage, are under power lines that could be problematic long term if topping occurs. These trees are not good candidates for transplanting. These trees are being removed due to site design.

Species: Platanus x hispanica ( London Plane Tree)
Quantity: 1
Tree Number: 7
Observations / Recommendations:

The London Plane Tree is a mature specimen and is in good shape. This tree is also along the street frontage, are under power lines that could be problematic long term if topping occurs. There is also some crowding with the adjacent Eucalyptus which could be a conflict for space in the future. This tree is not a good candidate for transplanting. Tree #7 is being removed due to site design.

Species: Prunus caroliniana ( Carolina Laurel Cherry)
Quantity: 1
Tree Number: 5
Observations / Recommendations:

The Carolina Cherry is a volunteer multi -stem shrub / tree growing under the Red flowering gum tree. This tree does not have a proper tree structure and should be removed. This tree is not a good candidate for transplanting. Tree #5 is being removed due to arborist recommendation.

Species: Pyrus calleryana ( Callery Pear)
Quantity: 2
Tree Number: 12, 13
Observations / Recommendations:

The Pear trees are in good shape and in the front of the Public Storage office. They are younger specimens and with proper care and maintenance will continue to thrive. Pear trees are susceptible to fire blight so proper pruning practices should be taken into consideration to limit the spread if infected. These trees are not good candidates for transplanting. These trees are being removed due to site design.

RECOMMENDATIONS FOR TREE PROTECTION DURING CONSTRUCTION Site preparation: All existing trees shall be fenced off 10' beyond the outside the drip line (foliar spread) of the tree. Alternatively, where this is not feasible, fence to the drip line of the tree. Where fencing is not possible, the trunk shall be protected straw waddle and orange snow fencing. The fence should be a minimum of six feet high, made of pig wire with steel stakes or any material superior in quality, such as cyclone fencing. Tree protection zone sign shall be affixed to fencing at appropriate intervals as determined by the arborist on site. If the fence is within the drip line of the trees, the foliar fringe shall be raised to offset the chance of limb breakage from construction equipment encroaching within the drip line. All contractors, subcontractors and other personnel shall be warned that encroachment within the fenced area is forbidden without the consent of the certified arborist on the job. This includes, but is not limited to, storage of lumber and other materials, disposal of paints, solvents or other noxious materials, parked cars, grading equipment or other heavy equipment. Penalties, based on the cost of remedial repairs and the evaluation guide published by the international society of arboriculture, shall be assessed for damages to the trees. Please see City of Mountain View tree protection specifications.

Grading/excavating: All grading plans that specify grading within the drip line of any tree, or within the distance from the trunk as outlined in the site preparation section above when said distance is outside the drip line, shall first be reviewed by a certified arborist. Provisions for aeration, drainage, pruning, tunneling beneath roots, root pruning or other necessary actions to protect the trees shall be outlined by an arborist. If trenching is necessary within the area as described above, said trenching shall be undertaken by hand labor and dug directly beneath the trunk of the tree. All roots 2 inches or larger shall be tunneled under and other roots shall be cut smoothly to the trunk side of the trench. The trunk side should be draped immediately with two layers of untreated burlap to a depth of 3 feet from the surface. The burlap shall be soaked nightly and left in place until the trench is back filled to the original level. An arborist shall examine the trench prior to back filling to ascertain the number and size of roots cut, so as to suggest the necessary remedial repairs.

Remedial repairs: An arborist shall have the responsibility of observing all ongoing activities that may affect the trees, and prescribing necessary remedial work to ensure the health and stability of the trees. This includes, but is not limited to, all arborist activities brought out in the previous sections. In addition, pruning, as outlined in the " pruning standards" of the western chapter of the International Society of Arboriculture, shall be prescribed as necessary. Fertilizing, aeration, irrigation, pest control and other activities shall be prescribed according to the tree needs, local site requirements, and state agricultural pest control laws. All specifications shall be in writing.

For pest control operations, consult the local county agricultural commissioner' s office for individuals licensed as pest control advisors or pest control operators.

Final inspection: Upon completion of the project, the arborist shall review all work undertaken that may impact the existing trees. Special attention shall be given to cuts and fills, compacting, drainage, pruning and future remedial work. An arborist should submit a final report in writing outlining the ongoing remedial care following the final inspection.

MAINTENANCE RECOMMENDATIONS FOR TREES TO REV
Regular maintenance, designed to promote plant health and vigor, ensures longevity of existing trees. Regular inspections and the necessary follow-up care of mulching, fertilizing, and pruning, can detect problems and correct them before they become damaging or fatal.

Tree Inspection: Regular inspections of mature trees at least once a year can prevent or reduce the severity of future disease, insect, and environmental problems. During tree inspection, four characteristics of tree vigor should be examined: new leaves or buds, leaf size, twig growth, and absence of crown dieback ( gradual death of the upper part of the tree). A reduction in the extension of shoots ( new growing parts), such as buds or new leaves, is a fairly reliable cue that the tree' s health has recently changed. Growth of the shoots over the past three years may be compared to determine whether there is a reduction in the tree's typical growth pattern. Further signs of poor tree health are trunk decay, crown dieback, or both. These symptoms often indicate problems that began several years before. Loose bark or deformed growths, such as trunk conks mushrooms), are common signs of stem decay. Any abnormalities found during these inspections, including insect activity and spotted, deformed, discolored, or dead leaves and twigs, should be noted and observed closely.

Mulching: Mulch, or decomposed organic material, placed over the root zone of a tree reduces environmental stress by providing a root environment that is cooler and contains more moisture than the surrounding soil. Mulch can also prevent mechanical damage by keeping machines such as lawn mowers and string trimmers away from the tree' s base. Furthermore, mulch reduces competition from surrounding weeds and turf. To be most effective, mulch should be placed 2 to 4 inches deep and cover the entire root system, which may be as far as 2 or 3 times the diameter of the branch spread of the tree. If the area and activities happening around the tree do not permit the entire area to be mulched, it is recommended that as much of the area under the drip line of the tree is mulched as possible. When placing mulch, care should be taken not to cover the actual trunk of the tree. This mulch -free area, 1 to 2 inches wide at the base, is sufficient to avoid moist bark conditions and prevent trunk decay. An organic mulch layer 2 to 4 inches deep of loosely packed shredded leaves, pine straw, peat moss, or composted wood chips is adequate. Plastic should not be used as it interferes with the exchange of gases between soil and air, which inhibits root growth. Thicker mulch layers, 5 to 6 inches deep or greater, may also inhibit gas exchange.

Fertilization: Trees require certain nutrients ( essential elements) to function and grow. Urban landscape trees may be growing in soils that do not contain sufficient available nutrients for satisfactory growth and development. In certain situations, it may be necessary to fertilize to improve plant vigor. Fertilizing a tree can improve growth; however, if fertilizer is not applied wisely, it may not benefit the tree at all and may even adversely affect the tree. Mature trees making satisfactory growth may not require fertilization. When considering supplemental fertilizer, it is important to consider nutrients deficiencies and how and when to amend the deficiencies.

Soil conditions, especially pH and organic matter content, vary greatly, making the proper selection and use of fertilizer a somewhat complex process. To that end, it is recommended that the soil be tested for nutrient content. A soil testing laboratory and can give advice on application rates, timing, and the best blend of fertilizer for each tree and other landscape plants on site.

Mature trees have expansive root systems that extend from 2 to 3 times the size of the leaf canopy. A major portion of actively growing roots is located outside the tree' s drip line.

Understanding the actual size and extent of a tree' s root system before applying fertilizer is paramount to determine quantity, type and rate at which to best apply fertilizer. Always follow manufacturer recommendations for use and application.

Pruning: Pruning is often desirable or necessary to remove dead, diseased, or insect -infested branches and to improve tree structure, enhance vigor, or maintain safety. Because each cut has the potential to change the growth of ( or cause damage to) a tree, no branch should be removed without reason. Removing foliage from a tree has two distinct effects on growth: ( 1) it reduces photosynthesis and, ( 2) it may reduce overall growth. Pruning should always be performed sparingly. Caution must be taken not to over -prune as a tree may not be able to gather and process enough sunlight to survive. Pruning mature trees may require special equipment, training, and experience. Arborists are equipped to provide a variety of services to assist in performing the job safely and reducing risk of personal injury and property damage ( See also ANSI A300 Part 1 Pruning Standards- https:// www.tcia. org).

Removal: There are circumstances when removal is necessary. An arborist can help decide whether or not a tree should be removed. Professionally trained arborists have the skills and equipment to safely and efficiently remove trees. Removal is recommended when a tree: ( 1) is dead, dying, or considered irreparably hazardous; (2) is causing an obstruction or is crowding and causing harm to other trees and the situation is impossible to correct through pruning; ( 3) is to be replaced by a more suitable specimen, and; ( 4) should be removed to allow for construction.

Pruning or removing trees, especially large trees, can be dangerous work. It should be performed only by those trained and equipped to work safely in trees.

TERMS AND CONDITIONS
The following terms and conditions apply to all oral and written reports and correspondence pertaining to consultations, inspections and activities of HMH.

1. The scope of any report or other correspondence is limited to the trees and conditions specifically mentioned in those reports and correspondence. HMH assumes no liability for the failure of trees or parts of trees, either inspected or otherwise. HMH assumes no responsibility to report on the condition of any tree or landscape feature not specifically requested by the named client.

2. No tree described in this report was climbed, unless otherwise stated. HMH does not take responsibility for any defects, which could have only been discovered by climbing. A full root collar inspection, consisting of excavating the soil around the tree to uncover the root collar and major buttress roots was not performed unless otherwise stated. HMH does not take responsibility for any root defects, which could only have been discovered by such an inspection.

3. HMH shall not be required to provide further documentation, give testimony, be deposed, or attend court by reason of this appraisal or report unless subsequent contractual arrangements are made, including payment of additional fees for such services as described by HMH or in the schedule of fees or contract.

4. HMH guarantees no warrantee, either expressed or implied, as to the suitability of the information contained in the reports for any reason. It is the responsibility of the client to determine applicability to his/ her case.

5. Any report and the values, observations and recommendations expressed therein represent the professional opinion of HMH, and the fee for services is in no manner contingent upon the reporting of a specified value nor upon any particular finding to be reported.

6. Any photographs, diagrams, graphs, sketches or other graphic material included in any report, being intended solely as visual aids, are not necessarily to scale and should not be construed as engineering reports or surveys, unless otherwise noted in the report. Any reproductions of graphic material or the work produced by other persons, is intended solely for clarification and ease of reference. Inclusion of said information does not constitute a representation by HMH as to the sufficiency or accuracy of that information.

7. Trees can be managed, but they cannot be controlled. To live near trees is to accept some degree of risk. The only way to eliminate all risk associated with trees is to eliminate all trees.
