• Evaluation of the data obtained from the investigation and an engineering analysis to provide recommendations for use in the project design and preparation of construction specifications. • Preparation of this report summarizing the results, conclusions, recommendations, and findings of our investigation.

PROPOSED CONSTRUCTION
We understand that design of the proposed development is currently underway; structural load information and other final details pertaining to the structures are unavailable. On a preliminary basis, it is understood the proposed development will include the construction of a new multi-family residential development. It is anticipated the buildings will be four- or five-story structures utilizing concrete slabon-grade construction. Foundation loads are anticipated to be moderately heavy. On-site paved areas and landscaping are also planned for the development of the project.

In the event, these structural or grading details are inconsistent with the final design criteria, the Soils Engineer should be notified so that we may update this writing as applicable.

SITE LOCATION, SITE HISTORY AND SITE DESCRIPTION
The site is roughly rectangular in shape and encompasses approximately 0.9 acres. The site is located approximately 200 feet southwest of El Camino Real at Distel Circle in Los Altos, California. The site has a street address of 330 Distel Circle. The site is predominately surrounded by commercial developments.

Site history was obtained by reviewing historical aerial photographs taken in 1948, 1991, 2010 and 2020. Review of the 1948 aerial photograph indicates that a rural residential development was located adjacent to the site. Two large linear excavations appeared to be present in the northern portion of the site.

Review of the 1991 aerial photograph indicates that a building and parking lot had been constructed at the site. Several trees were located along the edges of the site.

Review of the 2010 and 2020 aerial photographs indicate that the project site conditions appeared to be relatively similar to that noted in the 1991 aerial photograph.

Presently, the site conditions appear relatively similar to that noted in the previous aerial photographs.

The site is occupied by a commercial building with an associated parking lot and landscaped areas consisting of trees and shrubs. Buried utilities are located along the edges of the site and extend into portions of the site. The site is relatively level with no major changes in grade.

GEOLOGIC SETTING
The project area is located just south of San Francisco Bay and east of the Santa Cruz Mountains within the northern portion of the Coast Ranges Geomorphic Province of California. The Coast Ranges generally consist of an alternating series of parallel mountains and valleys located adjacent to the Pacific Krazan & Associates, Inc.

Coast. The bedrock units that form the range have been disrupted by intense folding, faulting, and crushing that occurred when the range was formed by the processes of plate tectonics. During the Jurassic and Cretaceous Periods (about 150 to 80 million years ago), the Pacific Oceanic Plate, which was progressively moving towards the east, collided with the North American Continental Plate, which was moving toward the west. This collision caused the less rigid Pacific Oceanic Plate to be subducted beneath the North American Continental Plate. The colliding motion of the two plates caused portions of the Pacific Oceanic Crust and overlying marine sediments to be piled onto the North American Continental Plate along the west coast of California. The resulting chaotic jumble of bedrock units scraped off onto the North American Plate, is known as the "Franciscan Assemblage" and comprises a large portion of the Coast Range Province. Subsequent development of a series of northwest-trending fault zones has further contributed to the deformation of the Coast Range.

The near-surface deposits in the vicinity of the subject site are indicated to be comprised of Holocene alluvial fan deposits consisting of sands, silt, and clays derived from erosion of local mountain ranges.

Deposits encountered on the subject site during exploratory drilling are discussed in detail in this report.

Seven major faults are located near the site: The Monte Vista-Shannon fault, the San Andreas fault, the Hayward fault, the Calaveras fault, the San Gregorio fault, the Zayante-Vergeles fault, and the Mount Diablo Thrust fault. The Monte Vista-Shannon fault and the San Andreas fault are located approximately 3.2 and 5.7 miles west of the site, respectively. The San Andreas fault was the source of the 1906 San Francisco Earthquake. The Hayward fault is located approximately 13 miles northeast of the site. The Hayward fault is considered capable of producing an earthquake event of magnitude 7.0.

The last recorded movement of the Hayward fault was in 1868. The Calaveras fault is located approximately 16 miles northeast of the site and is considered capable of producing an earthquake of magnitude of 6.9. The Zaynte-Vergeles fault is approximately 22 miles north of the site and is considered capable of producing an earthquake of magnitude 7.0. The San Gregorio fault and Mount Diablo Thrust are located approximately 17 miles west and 28 miles east of the site, respectively, and are also considered capable of producing large earthquakes. Although the site is in close proximity to several faults, the site is not within a State of California Earthquake Fault Zone or Special Study Zone for faulting.

The probability of one or more earthquakes of magnitude 6.7 or higher occurring in the San Francisco Bay Area within a 30-year period of time was evaluated by the U.S. Geological Survey (USGS) Working Group on California Earthquake Probabilities on a periodic basis. The result of the 2008 evaluation indicated a 63 percent likelihood that such an earthquake event will occur in the Bay Area between 2007 and 2036 (USGS 2008). The faults with the greater probability of a magnitude 6.7 or higher earthquake are the Hayward fault at 31 percent and the San Andreas fault at 21 percent.

The Alquist-Priolo Earthquake Fault Zoning Act went into effect in March, 1973. Since that time, the act has been amended 11 times (Hart, 2007). The purpose of the Act, as provided in CGS Special Publication 42 (SP 42), is to prohibit the location of most structures for human occupancy across the traces of active faults and to mitigate thereby the hazard of fault-rupture." The act was renamed the Alquist-Priolo Earthquake Fault Zoning Act in 1994, and at that time, the originally designated "Special Studies Zones" was renamed the "Earthquake Fault Zones."

The area of the subject site is not included on an Earthquake Fault Zones Map. At this time there is no Earthquake Fault Zones Map for the Mountain View Quadrangle. In addition, the site is not within a Fault-Rupture Hazard Zone. The nearest zoned faults are portions of the Monte Vista-Shannon, San Andreas and Hayward faults located more than 3.2 miles southwest, 5.7 miles southwest and 13 miles northeast of the subject site, respectively.

In 1990, the California State Legislature passed the Seismic Hazard Mapping Act to protect public safety from the effects of strong shaking, liquefaction, landslides, or other ground failure, and other hazards caused by earthquakes. The Act requires that the State Geologist delineate various seismic hazards zones on Seismic Hazards Zones Maps. Specifically, the maps identify areas where soil liquefaction and earthquake-induced landslides are most likely to occur. A site-specific geotechnical evaluation is required prior to permitting most urban developments within the mapped zones. The Act also requires sellers of real property within the zones to disclose this fact to potential buyers. The area of the subject site is located within the bounds of the hazard zone associated with liquefaction potential and is outside of the zones associated with landslide potential, on the Seismic Hazards Zones Mountain View Quadrangle, dated, October 18, 2006. In addition, the site is included on the U.S. Geological Survey map entitled "Liquefaction Susceptibility, Central San Francisco Bay Region, California" (U.S.

Geological Survey Open-File Report 2006-1037), dated 2006. The site is not located within an area identified as a moderate susceptibility to liquefaction. However, groundwater was encountered within the site during our subsurface investigation. Therefore, a liquefaction analysis is included in this report.

FIELD AND LABORATORY INVESTIGATIONS
Subsurface soil conditions were explored by drilling 4 borings to depths ranging from approximately 20 to 45 feet below existing site grade, using a truck-mounted drill rig. In addition, 2 bulk subgrade samples were obtained from the site for laboratory R-value testing. The approximate boring and bulk sample locations are shown on the site plan. During drilling operations, penetration tests were performed at regular intervals to evaluate the soil consistency and to obtain information regarding the engineering properties of the subsoils. Soil samples were retained for laboratory testing. The soils encountered were continuously examined and visually classified in accordance with the Unified Soil Classification System. A more detailed description of the field investigation is presented in Appendix A.

Laboratory tests were performed on selected soil samples to evaluate their physical characteristics and engineering properties. The laboratory testing program was formulated with emphasis on the evaluation of natural moisture, density, gradation, shear strength, consolidation potential, expansion potential, plasticity, R-value and moisture-density relationships of the materials encountered. In addition, chemical tests were performed to evaluate the soil-cement reactivity. Details of the laboratory test program and results of the laboratory tests are summarized in Appendix A. This information, along with the field observations, was used to prepare the final boring logs in Appendix A.

SOIL PROFILE AND SUBSURFACE CONDITIONS
Based on our findings, the subsurface conditions encountered appear typical of those found in the geologic region of the site. Portions of the site were covered by approximately 1 ½ inches of asphaltic concrete underlain by up to approximately 6½ inches of aggregate base. Within areas not covered by Krazan & Associates, Inc.

pavement, the upper soils consisted of approximately 6 to 12 inches of very loose clayey sand and clayey sand with gravel. These soils are disturbed, have low strength characteristics and are highly compressible when saturated.

Beneath the pavement section and loose surface soils, approximately 4 to 5 feet of medium dense to dense clayey sand with gravel was encountered. Field and laboratory tests suggest that these soils are moderately strong, slightly compressible and have a moderate expansion potential. Penetration resistance ranged from 34 to 52 blows per foot. Dry densities ranged from 113 to 125 pcf. A representative soil sample consolidated approximately 2½ percent under a 2 ksf load when saturated. A representative soil sample had an angle of internal friction of 43 degrees.

Below 4 to 5½ feet, layers of predominately medium dense to very dense clayey sand and silty sand or stiff to hard sandy clay were encountered. These soils were intermixed with varying amounts of gravel.

Field and laboratory tests suggest that these soils are moderately strong and slightly compressible.

Penetration resistance ranged from 10 blows per foot to greater than 50 blows per 6 inches. Dry densities ranged from 95 to 127 pcf. Representative soil samples contained approximately 13 to 63 percent fines. These soils had similar strength characteristics as the upper soils and extended to the tennination depth of our borings.

For additional information about the soils encountered, please refer to the logs of borings in Appendix A.

GROUNDWATER
Test boring locations were checked for the presence of groundwater during and immediately following the drilling operations. Free groundwater was encountered at approximately 31 to 36 feet below existing site grade. Historic high groundwater was estimated to be 21 feet based on information obtained from the California Geological Survey.

It should be recognized that water table elevations may fluctuate with time, being dependent upon seasonal precipitation, irrigation, land use and climatic conditions, as well as other factors. Therefore, water level observations at the time of the field investigation may vary from those encountered during the construction phase of the project. The evaluation of such factors is beyond the scope of this report.

SOIL LIQUEFACTION
Soil liquefaction is a state of soil particle suspension, caused by a complete loss of strength when the effective stress drops to zero. Liquefaction normally occurs in soils, such as sands, in which the strength is purely frictional. However, liquefaction has occurred in soils other than clean sands. Liquefaction usually occurs under vibratory conditions, such as those induced by seismic events.

To evaluate the liquefaction potential of the site, the following items were evaluated:

The soils encountered within a depth of 45 feet on the project site predominately consist of medium dense to very dense clayey sands and silty sands or stiff to hard sandy clays. Groundwater was encountered below the site at approximate depths of 31 to 36 feet during subsurface exploration.

The potential for soil liquefaction during a seismic event was evaluated using the LIQUEFYPRO computer program (version 5.8h) developed by CivilTech Software. For the analysis, a maximum earthquake magnitude of 7.51 Mw and a peak horizontal ground surface acceleration of 0.917g were considered appropriate for the liquefaction analysis. A groundwater depth of 21 feet was used for the analysis. The computer analysis indicates that soils above a depth of 21 feet are non-liquefiable due to the absence of groundwater. The soils between depths of 28 feet to 36 feet in Boring Bl and in Boring B4 at about 28 to 37 feet are considered to be slightly to moderately liquefiable. The analysis indicates that the total and differential seismic induced settlement is not anticipated to exceed 2½ inches and 1 ¼ inches, respectively. Accordingly, the liquefaction potential at the site is considered moderate and design of the development the liquefaction potential should consider the anticipated settlements in the project design.

CONCLUSIONS AND RECOMMENDATIONS
Based on the findings of our field and laboratory investigations, along with previous geotechnical experience in the project area, the following is a summary of our evaluations, conclusions, and recommendations.

Administrative Summary
In brief, the subject site and soil conditions, with the exception of the existing development, moderate expansion potential of the on-site clayey soils and estimated settlement associated with the potential for liquefaction, appear to be conducive to the development of the project. The surface soils have a loose consistency. These soils are disturbed, have low strength characteristics and are highly compressible when saturated. Accordingly, it is recommended that the surface soils be recompacted. This compaction effort should stabilize the surface soils and locate any unsuitable or pliant areas not found during our field investigation.

Fill material was not encountered in our borings. However, fill may be present between and beyond our boring locations. The extent of fill material was determined based on limited test borings and visual observation. Verification of the extent of fill should be determined during site grading. It is recommended that fill soils which have not been properly compacted and certified be excavated and Krazan & Associates, Inc.

stockpiled so that the native soils can be prepared properly. It is anticipated the fill material will be suitable for reuse as Engineered Fill, provided it is cleansed of excessive organics and debris. However, supplemental testing would be required for re-use as non-expansive Engineered Fill.

The site is occupied by existing structures with associated concrete and asphaltic concrete pavements. In addition, several structures are located within the project site vicinity. Associated with these developments are buried structures, such as utilities. Any surface or buried structures, including utilities, encountered during construction should be properly removed and the resulting excavations backfilled. It is suspected demolition of the existing structures will disturb the upper soils. Areas disturbed by demolition activities should be excavated to firm native ground. The resulting excavations should be backfilled with Engineered Fill. This compaction effort should stabilize the upper soils and locate any unsuitable or pliant areas not found during our field investigation.

Several trees and shrubs are located within portions of the site. If not utilized for the proposed development, tree and shrub removal operations should include roots greater than 1 inch in diameter.

The resulting excavations should be backfilled with Engineered Fill compacted to a minimum of 90 percent of maximum density based on ASTM Test Method D1557.

The on-site clayey soils have a moderate swell potential. The clayey soils in their present condition present a minor to moderate hazard to construction in terms of possible post-construction movement of slab-on-grade construction. To reduce potential soil movement related to swell potential of the clayey soils, it is recommended that conventional slabs-on-grade and exterior flatwork areas be supported by at least 12 inches of non-expansive Engineered Fill. The fill material should be a well-graded silty sand or sandy silt soil. A clean sand or very sandy soil is not acceptable for this purpose. A sandy soil will allow the surface water to drain into the expansive soils below, which may result in soil swelling. The replacement soils and/or upper 12 inches of Imported Fill soils should meet the specifications as described under the subheading Engineered Fill. The replacement soils should extend 5 feet beyond the. perimeter of slab-on-grade areas. The non-expansive replacement soils should be compacted to at least 90 percent ofrelative compaction based on ASTM Test Method D1557. The exposed native soils in the excavation should not be allowed to dry out and should be kept continually moist, prior to backfilling.

In addition, it is recommended that slab-on-grade, continuous footings and slabs be nominally reinforced to reduce cracking and vertical off-set.

As an alternative to the use of non-expansive soils, the upper 12 inches of soil supporting conventional slab areas can consist of lime-treated clayey soils. The lime-treated soils should be recompacted to a minimum of 90 percent of maximum density. Preliminary application rate of lime should be 5 percent by dry weight. The lime material should be calcium oxide, commonly known as quick-lime. The clayey soils should be at or near optimum moisture during the mixing operations.

Based on the soil liquefaction analysis performed within the site, the estimated total seismic-induced settlement is less than 2½ inches. Differential settlement caused by a seismic event is estimated to be less than 1 ¼ inches. The anticipated differential settlement is estimated over a horizontal distance of Krazan & Associates, Inc.

100 feet. The seismic settlements would develop if liquefaction of the underlying saturated subsoils were to occur during a seismic event. If these potential movements are not tolerable, mitigation measures are recommended to reduce structural damage due to soil liquefaction.

After completion of the recommended site preparation and over-excavation, the site should be suitable for shallow footing support. The proposed structure footings may be designed utilizing an allowable bearing pressure of 2,500 psf for dead-plus-live loads. If the structure is supported on geogridreinforced Engineered Fill, this value can be increased to 3,500 psf. Footings should have a minimum embedment of 24 inches. As an alternative, the proposed structure may be designed utilizing a posttensioned or structural slab system. Utilization of post-tensioned or structural slabs designed utilizing the design parameters provided in this report, will eliminate the requirement for 12 inches of nonexpansive or lime-treated Engineered Fill below slab-on-grade. However, the previously recommended densification of the upper native soils and fill material at the site should still be performed.

Groundwater Influence on Structures/Construction
During our recent field investigation groundwater was encountered at approximately 31 to 36 feet below existing site grade. Historic high groundwater level for the site was determined to be 21 feet. Therefore, dewatering and/or waterproofing may be required should structures or excavations extend below this depth. If groundwater is encountered, our firm should be consulted prior to dewatering the site.

Installation of a standpipe piezometer is suggested prior to construction should groundwater levels be a concern.

In addition to the groundwater level, if earthwork is performed during or soon after periods of precipitation, the subgrade soils may become saturated, "pump," or not respond to densification techniques. Typical remedial measures include: discing and aerating the soil during dry weather; mixing the soil with dryer materials; removing and replacing the soil with an approved fill material; or mixing the soil with an approved lime or cement product. Our firm should be consulted prior to implementing remedial measures to observe the unstable subgrade conditions and provide appropriate recommendations.

Site Preparation - General
General site clearing should include removal of vegetation; ex1stmg utilities; structures including foundations; basement walls and floors; existing stockpiled soil; trees and associated root systems; rubble; rubbish; and any loose and/or saturated materials. Site stripping should extend to a minimum depth of 2 to 4 inches, or until all organics in excess of 3 percent by volume are removed. Deeper stripping may be required in localized areas. These materials will not be suitable for reuse as Engineered Fill. However, stripped topsoil may be stockpiled and reused in landscape or non-structural areas.

stockpiled so that the native soils can be prepared properly. It is anticipated the fill material will be suitable for reuse as Engineered Fill, provided it is cleansed of excessive organics and debris. However, supplemental testing would be required for re-use as non-expansive Engineered Fill.

Existing structures are located within the site and vicinity. Associated with these developments are buried structures, such as utility lines. Any surface or buried structures, such as utilities or loosely backfilled excavations, encountered during construction should be properly removed and the resulting excavations backfilled. After demolition activities, it is recommended that these disturbed soils be removed and/or recompacted. Excavations, depressions, or soft and pliant areas extending below planned, finished subgrade levels should be cleaned to firm, undisturbed soil and backfilled with Engineered Fill. In general, any septic tanks, debris pits, cesspools, or similar structures should be entirely removed. Concrete footings should be removed to an equivalent depth of at least 3 feet below proposed footing elevations or as recommended by the Soils Engineer. Any other buried structures should be removed in accordance with the recommendations of the Soils Engineer. The resulting excavations should be backfilled with Engineered Fill.

Several trees and shrubs are located within portions of the site. If not utilized for the proposed development, tree and shrub removal operations should include roots greater than 1 inch in diameter.

The resulting excavations should be backfilled with Engineered Fill compacted to a minimum of 90 percent of maximum density based on ASTM Test Method D1557.

Following stripping, fill removal, and demolition activities, it is recommended that at a minimum, the upper 24 inches of exposed subgrade soils beneath existing site grade or 12 inches below the bottom of planned footings, whichever is deeper, in the building pad areas be excavated, worked until uniform and free from large clods, moisture-conditioned to a minimum of 2 percent above optimum moisture content, and recompacted to a minimum of90 percent of maximum density based on ASTM Test Method D1557.

Limits of recompaction should extend a minimum of 5 feet beyond structural elements. Prior to backfilling, the bottom of the excavation should be proof-rolled and observed by Krazan & Associates, Inc. to verify stability. Soft or pliant areas should be excavated to finn native ground. This compaction effort should stabilize the upper soils and locate any unsuitable or pliant areas not found during our field investigation.

Following stripping, fill removal, and demolition activities, it is recommended that at a minimum, the upper 12 inches of exposed subgrade soils beneath the exterior flatwork and pavement areas be excavated, worked until uniform and free from large clods, moisture-conditioned to a minimum of 2 percent above optimum moisture content, and recompacted to a minimum of 90 percent of maximum density based on ASTM Test Method D1557. Limits of recompaction should extend a minimum of 2 feet beyond flatwork and pavements. Prior to backfilling, the bottom of the excavation should be proofrolled and observed by Krazan & Associates, Inc. to verify stability. Soft or pliant areas should be excavated to firm native ground. This compaction effort should stabilize the upper soils and locate any unsuitable or pliant areas not found during our field investigation.

It is recommended that any uncertified fill material encountered within pavement areas be removed and/or recompacted. The fill material should be moisture-conditioned to near optimum moisture and recompacted to a minimum of 90 percent of maximum density based on ASTM Test Method Dl557. As an alternative, the Owner may elect not to recompact the existing fill within paved areas. However, the Owner should be aware that the paved areas may settle which may require annual maintenance. At a minimum, it is recommended that the upper 12 inches of subgrade soil be moisture-conditioned as necessary and recompacted to a minimum of 90 percent of maximum density based on ASTM Test Method D1557.

It is recommended that the upper 12 inches of soil within proposed conventional slab-on-grade and exterior flatwork areas consist of non-expansive Engineered Fill or lime-treated Engineered Fill. The fill placement serves two functions: 1) it provides a uniform amount of soil which will more evenly distribute the soil pressures and 2) it reduces moisture content fluctuation in the clayey material beneath the building area. The non-expansive fill material should be a well-graded silty sand or sandy silt soil.

A clean sand or very sandy soil is not acceptable for this purpose. A sandy soil will allow the surface water to drain into the expansive ?layey soil below, which may result in soil swelling. Imported Fill should be approved by the Soils Engineer prior to placement. The fill should be placed as specified as Engineered Fill. In addition, it is recommended footings and concrete slabs-on-grade be nominally reinforced.

The upper soils, during wet winter months, become very moist due to the absorptive characteristics of the soil. Earthwork operations performed during winter months may encounter very moist unstable soils, which may require removal to grade a stable building foundation. Project site winterization consisting of placement of aggregate base and protecting exposed soils during the construction phase should be performed.

A representative of our firm should be present during all site clearing and grading operations to test and observe earthwork construction. This testing and observation is an integral part of our service, as acceptance of earthwork construction is dependent upon compaction and stability of the material. The Soils Engineer may reject any material that does not meet compaction and stability requirements.

Further recommendations of this report are predicated upon the assumption that earthwork construction will conform to recommendations set forth in this section and the Engineered Fill section.

Supplemental Site Preparation - Geogrid
Subsurface soils within the site are prone to liquefaction under high groundshaking acceleration during an earthquake. If the proposed structure will be constructed over a geogrid mat the building area should be excavated to a minimum depth of 5 feet and the resulting excavation should be backfilled with a layered system of Engineered Fill and geogrid reinforcement. The depth of the over-excavation should be measured from existing ground or rough pad grade, whichever is deeper.

The first layer of geogrid reinforcement will be placed directly at the bottom of the excavation. The geogrid material should be overlapped a minimum of 3 feet in all directions. The geogrid strips should be "shingled" such that the exposed geogrid edge is opposite the direction of fill placement (as roof shingles to rain runoff). The interlock between the geogrid and Engineered Fill will provide load transfer. No vehicles may traverse the geogrid prior to placement of the Engineered Fill cover.

The next layer of geogrid should be pla~ed on top of the compacted Engineered Fill. This and subsequent layers need only be overlapped a minimum of 1 foot on all sides. The geogrid strips of this layer, and all subsequent layers within the footprint, should be placed with lengths perpendicular to those in the layer immediately below. The fill soils excavated from the area beneath the structure may be moisture-conditioned and recompacted between geogrid layers as reinforced fill. The reinforced fill should be conditioned from 2 to 5 percent above optimum moisture and recompacted to a minimum of 90 percent of maximum density based on ASTM D1557 Test Method.

A total of 4 geogrid layers, including the layer at the base of the excavation, should be installed at vertical increments of 1 foot. The geogrid layers should extend to a minimum of 5 feet beyond the exterior footing perimeter of the structure. The geogrid reinforcement fabric should consist of Tensar® BX 6200 or Triax TX-7 Geogrid, or equivalent. Any additional unstable soils within building areas should be excavated and backfilled with Engineered Fill as requested by the Soil Engineer.

It is recommended that the building site be excavated at once, and soils be stockpiled. The geogrid and excavated soil may then be placed and recompacted as recommended herein. Alternatively, the Contractor may elect to excavate the site in two stages, where excavated soil can be stockpiled over onehalf of the site while the other half is mitigated. However, if the Contractor elects the option of two stages over the preferred option of using one stage, a minimum of 5 feet of geogrid from the first half should overlap the second half. Furthermore, the overlapping geogrid should be protected from damages, which may be caused by operating equipment. It is further recommended that flexible utility connections be used for the project.

Engineered Fill
The organic-free, on-site, upper native soils and fill material are predominately clayey sands and sandy clays. These soils contained varying amounts of gravel. The clayey soils will not be suitable for reuse as non-expansive Engineered Fill. The clayey soils will be suitable for reuse for fill placement within the upper 12 inches of conventional slab-on-grade and exterior flatwork areas, provided they are limetreated. The preliminary application rate of lime should be 5 percent by dry weight. The lime material should be calcium oxide, commonly known as quick-lime. The clayey soils should be above optimum moisture-condition during mixing operations. Additional testing is recommended to determine the appropriate application rate of lime prior to placement. These clayey soils will be suitable for reuse as General Engineered Fill, within pavement areas, structural areas supported by post-tensioned or structural slabs, and below 12 inches from finished pad grade in building areas, provided they are cleansed of excessive organics, debris, and moisture-conditioned to at least 2 percent above optimum moisture. It is recommended that additional testing be performed on the on-site soils and fill material to evaluate the physical and index properties prior to reuse as Engineered Fill.

The preferred materials specified for Engineered Fill are suitable for most applications with the exception of exposure to erosion. Project site winterization and protection of exposed soils during the construction phase should be the sole responsibility of the Contractor, since he has complete control of the project site at that time.

Imported Fill should consist of a well-graded, slightly cohesive, fine silty sand or sandy silt soil, with relatively impervious characteristics when compacted. This material should be approved by the Soils Engineer prior to use and should typically possess the following characteristics:

Percent Passing No. 200 Sieve 20 to 50
Plasticity Index 10 maximum
UBC Standard 29-2 Expansion Index 15 maximum
Fill soils should be placed in lifts approximately 6 inches thick, moisture-conditioned to a minimum of 2 percent above optimum moisture content, and compacted to achieve at least 90 percent of maximum density based on ASTM D1557. Additional lifts should not be placed if the previous lift did not meet the required dry density or if soil conditions are not stable.

Drainage and Landscaping
The ground surface should slope away from building pad and pavement areas toward appropriate drop inlets or other surface drainage devices. In accordance with Section 1804 of the 2019 California Building Code, it is recommended that the ground surface adjacent to foundations be sloped a minimum of 5 percent for a minimum distance of 10 feet away from structures, or to an approved alternative means of drainage conveyance. Swales used for conveyance of drainage and located within 10 feet of foundations should be sloped a minimum of 2 percent. Impervious surfaces, such as pavement and exterior concrete flatwork, within 10 feet of building foundations should be sloped a minimum of 1 percent away from the structure. Drainage gradients should be maintained to carry all surface water to collection facilities and off-site. These grades should be maintained for the life of the project.

Slots or weep holes should be placed in drop inlets or other surface drainage devices in pavement areas to allow free drainage of adjoining base course materials. Cutoff walls should be installed at pavement edges adjacent to vehicular traffic areas these walls should extend to a minimum depth of 12 inches below pavement subgrades to limit the amount of seepage water that can infiltrate the pavements.

Where cutoff walls are undesirable subgrade drains can be constructed to transport excess water away from planters to drainage interceptors. If cutoff walls can be successfully used at the site, construction of subgrade drains is considered unnecessary.

Utilit Trench Backfill
Utility trenches should be excavated according to accepted engineering practice following OSHA (Occupational Safety and Health Administration) standards by a Contractor experienced in such work.

The responsibility for the safety of open trenches should be borne by the Contractor. Traffic and Krazan & Associates, Inc.

vibration adjacent to trench walls should be reduced; cyclic wetting and drying of excavation side slopes should be avoided. Depending upon the location and depth of some utility trenches, groundwater flow into open excavations could be experienced; especially during or following periods of precipitation.

Utility trench backfill placed in or adjacent to buildings and exterior slabs should be compacted to at least 90 percent of maximum density based on ASTM Test Method Dl557. The utility trench backfill placed in pavement areas should be compacted to at least 90 percent of maximum density based on ASTM Test Method Dl557. Pipe bedding should be in accordance with pipe manufacturer's recommendations.

Sandy and gravelly soil conditions were encountered at the site. These cohesionless soils have a tendency to cave in trench wall excavation. Shoring or sloping back trench sidewalls may be required within these sandy and gravelly soils.

The Contractor is responsible for removing all water-sensitive soils from the trench regardless of the backfill location and compaction requirements. The Contractor should use appropriate equipment and methods to avoid damage to the utilities and/or structures during fill placement and compaction.

Foundations - Conventional
After completion of the recommended site preparation and over-excavation, the site should be suitable for shallow footing support. The proposed structures may be supported on a shallow foundation system bearing on a minimum of 12 inches of Engineered Fill. Spread and continuous footings can be designed for the following maximum allowable soil bearing pressures:

Load Allowable Loadin2
Dead Load Only 1,875 psf
Dead-Plus-Live Load 2,500 psf
Total Load, Including Wind or Seismic Loads 3,325 psf
The footings should have a minimum embedment depth of 24 inches below pad subgrade (soil grade) or adjacent exterior grade, whichever is lower. Footings should have a minimum width of 12 inches, regardless of load.

The footing excavations should not be allowed to dry out any time prior to pouring concrete. It is recommended that footings be reinforced by at least one No. 4 reinforcing bar in both top and bottom.

Resistance to lateral footing displacement can be computed using an allowable friction factor of 0.35 acting between the base of foundations and the supporting subgrade. Lateral resistance for footings can alternatively be developed using an allowable equivalent fluid passive pressure of 275 pounds per cubic foot acting against the appropriate vertical footing faces. The frictional and passive resistance of the soil may be combined without reduction in determining the total lateral resistance. A ½ increase in the value above may be used for short duration, wind, or seismic loads.

The total static movement is not expected to exceed 1 inch. Differential static movement should be less than ½ inch. Most of the static settlement is expected to occur during construction, as the loads are applied. However, additional post-construction movement may occur ifthe foundation soils are flooded or saturated. The total seismic-induced settlement is estimated to be less than 2½ inches. The estimated differential settlement associated with a seismic event for a structure supported on Engineered Fill is less than 1 ¼ inch. The anticipated differential settlement associated with a seismic event is estimated over a horizontal distance of 100 feet. The seismic settlements would develop if liquefaction of the underlying saturated soils were to occur during a seismic event.

Foundations - Conventional (Supported on Geogrid Reinforced Fill) After completion of the recommended site preparation and over-excavation, the site should be suitable for shallow footing support.

Foundations - Post-Tension or Structural Slab
KA No. 042-21020
Page No. 15
The building may be supported on a post-tension slab or structural slab/foundation system. Utilization of a post-tensioned or structural slab designed utilizing the design parameters provided in this report, will eliminate the requirement for 12 inches of non-expansive or lime-treated Engineered Fill below slab-on-grade. However, the previously recommended densification of the upper native soils and fill material at the site should still be performed. Recommendations for a structural slab system are also provided herein. After completion of the recommended site preparation and over-excavations, the posttension or structural slab foundation can be designed utilizing allowable bearing pressure of 1,500 pounds per square foot for dead-plus-live loads. This value may be increased ½ for short duration loads such as wind or seismic. The slab may be designed using a modulus of subgrade reaction (k) of 75 pounds per square inch per inch (pci). The thickened edges of the slab should have a minimum depth of 18 inches below pad grade (soil grade) or exterior grade, whichever is lower. Ultimate design of the slab and reinforcement should be performed by the project Structural Engineer.

The thickness of the slab-on-grade and locations and sizing of stiffening beams (if used) should be determined by the structural consultant during a subsequent structural analysis, which incorporates our design recommendations, including a deepened perimeter or edge section. Post-tensioned slab-on-grade foundations should be structurally designed to resist or distribute the stresses that are anticipated to develop as the result of supporting soil movement. The following preliminary parameters are recommended for use in the structural design of the post-tensioned slab-on-grade foundations in accordance with Design of Post-Tensioned Slabs-on-Ground, 3rd Edition, by the Post-Tensioning Institute. In addition, the computer software program Volflo 1.5, by Geostructural Tool Kit, Inc. was also utilized in the analyses. The recommended edge moisture variation ( em) and differential swell (Ym) values for use in preliminary design of post-tensioned slabs are as follows:

Edge Moisture Variation Distance:

Center lift, em = 9 feet
Edge lift, em= 4.8 feet
Estimated Differential Swell:

Center lift, Ym = 1 inch
Edge lift, Ym = 1 ¼ inch
To aid in reducing the potential for differential soil movement associated with shrinkage and swelling of the fine-grained soils due to changes in moisture contents with changing seasons and landscaping, we recommend that the exterior edge of the slab be deepened to provide a moisture cut-off around the perimeter of the building. The deepened edge should extend at least 18 inches below the top of the pad grade, where the top of pad grade is defined as the grade beneath the bottom of the capillary moisture break gravel course or the adjacent exterior subgrade, whichever is deeper. hnport and placement of the amount of fill required for the building pad should correspond to the import fill specifications.

Resistance to lateral displacement can be computed using an allowable friction factor of 0.35 acting between the base of foundations and the supporting subgrade. Lateral resistance for footings can a,.ematively be developed using an allowable equivalent fluid passive pressure of 275 pounds per cubic Krazan & Associates, Inc.

foot acting against the appropriate vertical footing faces. The frictional and passive resistance of the soil may be combined without reduction in determining the total lateral resistance. A ½ increase in the above value may be used for short duration, wind, or seismic loads.

The structural or post-tensioned slab foundations should be designed to withstand a combined total static and seismic settlement of 3 inches, and a differential settlement of up to 2 inches. Most of the static settlement is expected to occur during construction as the loads are applied. However, additional postconstruction movement may occur if the foundation soils are flooded or saturated. The anticipated differential settlement is estimated over the width of the building. The seismic settlements would develop only if liquefaction of the underlying saturated soils were to occur during a seismic event.

Floor Slabs and Exterior Flatwork
To reduce post-construction soil movement beneath floor slabs and exterior flatwork, it is recommended that mitigation measures be performed. For conventional slab-on-grade, it is recommended that the upper 12 inches of soil consist of non-expansive or lime-treated Engineered Fill.

In areas that will utilize moisture-sensitive floor coverings, concrete slab-on-grade floors should be underlain by a water vapor retarder. The water vapor retarder should be installed in accordance with accepted engineering practice. The water vapor retarder should consist of a vapor retarder sheeting underlain by a minimum of 3 inches of compacted, clean, gravel of ¾-inch maximum size. To aid in concrete curing an optional 2 to 4 inches of granular fill may be placed on top of the vapor retarder. The granular fill should consist of damp clean sand with at least 10 to 30 percent of the sand passing the 100 sieve. The sand should be free of clay, silt, or organic material. Rock dust which is manufactured sand from rock crushing operations is typically suitable for the granular fill. This granular fill material should be compacted.

It is recommended that the concrete slabs be reinforced at a minimum with No. 3 reinforcing bars, placed at 18 inches on center in each direction within the slabs middle third, to reduce crack separation and possible vertical offset at the cracks. Thicker floor slabs with increased concrete strength and reinforcement should be designed wherever heavy concentrated loads, heavy equipment, or machinery is anticipated.

The exterior floors should be poured separately in order to act independently of the walls and foundation system. Exterior finish grades should be sloped a minimum of 2 percent away from all interior slab areas to preclude ponding of water adjacent to the structures. All fills required to bring the building pads to grade should be Engineered Fills.

Moisture within the structure may be derived from water vapors, which were transformed from the moisture within the soils. This moisture vapor can travel through the vapor membrane and penetrate the slab-on-grade. This moisture vapor penetration can affect floor coverings and produce mold and mildew in the structure. To reduce moisture vapor intrusion, it is recommended that a vapor retarder be installed. It is recommended that the utility trenches within the structure be compacted, as specified in our report, to reduce the transmission of moisture through the utility trench backfill. Special attention to the immediate drainage and irrigation around the building is recommended. Positive drainage should be Krazan & Associates, Inc.

established away from the structure and should be maintained throughout the life of the structure.

Ponding of water should not be allowed adjacent to the structure. Over-irrigation within landscaped areas adjacent to the structure should not be performed. In addition, ventilation of the structure (i.e. ventilation fans) is recommended to reduce the accumulation of interior moisture.

Lateral Earth Pressures and Retaining Walls
Walls retaining horizontal backfill and capable of deflecting a minimum of 0.1 percent of its height at the top may be designed using an equivalent fluid active pressure of 50 pounds per square foot per foot of depth. Walls that are incapable of this deflection or walls that are fully constrained against deflection may be designed for an equivalent fluid at-rest pressure of 70 pounds per square foot per foot per depth.

Expansive soils should not be used for backfill against walls. The wedge of non-expansive backfill material should extend from the bottom of each retaining wall outward and upward at a slope of 2: 1 (horizontal to vertical) or flatter. The stated lateral earth pressures do not include the effects of hydrostatic water pressures generated by infiltrating surface water that may accumulate behind the retaining walls; or loads imposed by construction equipment, foundations, or roadways.

During grading and backfilling operations adjacent to any walls, heavy equipment should not be allowed to operate within a lateral distance of 5 feet from the wall, or within a lateral distance equal to the wall height, whichever is greater, to avoid developing excessive lateral pressures. Within this zone, only hand operated equipment ("whackers," vibratory plates, or pneumatic compactors) should be used to compact the backfill soils.

Retaining and/or below grade walls should be drained with either perforated pipe encased in freedraining gravel or a prefabricated drainage system. The gravel zone should have a minimum width of 12 inches wide and should extend upward to within 12 inches of the top of the wall. The upper 12 inches of backfill should consist of native soils, concrete, asphaltic concrete or other suitable backfill to reduce surface drainage into the wall drain system. The aggregate should conform to Class 2 permeable materials graded in accordance with the CalTrans Standard Specifications (2018). Prefabricated drainage systems, such as Miradrain®, Enkadrain®, or an equivalent substitute, are acceptable alternatives in lieu of gravel provided they are installed in accordance with the manufacturer's recommendations. If a prefabricated drainage system is proposed, our firm should review the system for final acceptance prior to installation.

Drainage pipes should be placed with perforations down and should discharge in a non-erosive manner away from foundations and other improvements. The pipes should be placed no higher than 6 inches above the heel of the wall in the center line of the drainage blanket and should have a minimum diameter of 4 inches. Collector pipes may be either slotted or perforated. Slots should be no wider than ½ inch in diameter, while perforations should be no more than ¼ inch in diameter. If retaining walls are less than 6 feet in height, the perforated pipe may be omitted in lieu of weep holes on 4 feet maximum spacing.

The weep holes should consist of 4-inch diameter holes (concrete walls) or unmortared head joints (masonry walls) and not be higher than 18 inches above the lowest adjacent grade. Two 8-inch square overlapping patches of geotextile fabric ( conforming to the CalTrans Standard Specifications for "edge drains") should be affixed to the rear wall opening of each weep hole to retard soil piping.

It is recommended that any uncertified fill material encountered within pavement areas be removed and/or recompacted. The fill materials should be moisture-conditioned to near optimum moisture and recompacted to a minimum of 90 percent of maximum density based on ASTM Test Method D 1557. As an alternative, the Owner may elect not to recompact the existing fill within paved areas. However, the Owner should be aware that the paved areas may settle which may require annual maintenance. At a minimum, it is recommended that the upper 12 inches of subgrade soil be moisture-conditioned to a minimum of 2 percent above optimum moisture content and recompacted to a minimum of 90 percent of maximum density based on ASTM Test Method D1557.

Soil Cement Reactivitv
KA No. 042-21020
Page No. 20
Excessive sulfate in either the soil or native water may result in an adverse reaction between the cement in concrete ( or stucco) and the soil. HUD/FHA and CBC have developed criteria for evaluation of sulfate levels and how they relate to cement reactivity with soil and/or water.

Soil samples were obtained from the site and tested in accordance with State of California Materials Manual Test Designation 417. The sulfate concentrations detected in these soil samples were less than 150 ppm and are below the maximum allowable values established by HUD/FHA and CBC. However, it is recommended that a Type II cement be used within the concrete to compensate for sulfate reactivity with the cement.

Compacted Material Acceptance
Compaction specifications are not the only criteria for acceptance of the site grading or other such activities. However, the compaction test is the most universally recognized test method for assessing the performance of the Grading Contractor. The numerical test results from the compaction test cannot be used to predict the engineering performance of the compacted material. Therefore, the acceptance of compacted materials will also be dependent on the stability of that material. The Soils Engineer has the option of rejecting any compacted material regardless of the degree of compaction if that material is considered to be unstable or if future instability is suspected. A specific example of rejection of fill material passing the required percent compaction is a fill which has been compacted with an in-situ moisture content significantly less than optimum moisture. This type of dry fill (brittle fill) 1s susceptible to future settlement if it becomes saturated or flooded.

Testing and Inspection
A representative of Krazan & Associates, Inc. should be present at the site during the earthwork activities to confirm that actual subsurface conditions are consistent with the exploratory fieldwork.

This activity is an integral part of our service, as acceptance of earthwork construction is dependent upon compaction testing and stability of the material. This representative can also verify that the intent of these recommendations is incorporated into the project design and construction. Krazan & Associates, Inc. will not be responsible for grades or staking, since this is the responsibility of the Prime Contractor.

LIMITATIONS
Soils Engineering is one of the newest divisions of Civil Engineering. This branch of Civil Engineering is constantly improving as new technologies and understanding of earth sciences advance. Although your site was analyzed using the most appropriate and most current techniques and methods, Krazan & Associates, Inc.

undoubtedly there will be substantial future improvements in this branch of engineering. In addition to advancements in the field of Soils Engineering, physical changes in the site, either due to excavation or fill placement, new agency regulations, or possible changes in the proposed structure after the soils report is completed may require the soils report to be professionally reviewed. In light of this, the Owner should be aware that there is a practical limit to the usefulness of this report without critical review. Although the time limit for this review is strictly arbitrary, it is suggested that 2 years be considered a reasonable time for the usefulness of this report.

Foundation and earthwork construction is characterized by the presence of a calculated risk that soil and groundwater conditions have been fully revealed by the original foundation investigation. This risk is derived from the practical necessity of basing interpretations and design conclusions on limited sampling of the earth. The recommendations made in this report are based on the assumption that soil conditions do not vary significantly from those disclosed during our field investigation. If any variations or undesirable conditions are encountered during construction, the Soils Engineer should be notified so that supplemental recommendations may be made.

The conclusions of this report are based on the information provided regarding the proposed construction. If the proposed construction is relocated or redesigned, the conclusions in this report may not be valid. The Soils Engineer should be notified of any changes so the recommendations may be reviewed and re-evaluated.

This report is a Geotechnical Engineering Investigation with the purpose of evaluating the soil conditions in terms of foundation design. The scope of our services did not include any Environmental Site Assessment for the presence or absence of hazardous and/or toxic materials in the soil, groundwater, or atmosphere; or the presence of wetlands. Any statements, or absence of statements, in this report or on any boring log regarding odors, unusual or suspicious items, or conditions observed, are strictly for descriptive purposes and are not intended to convey engineering judgment regarding potential hazardous and/or toxic assessment.

The geotechnical engineering information presented herein is based upon professional interpretation utilizing standard engineering practices and a degree of conservatism deemed proper for this project. It is not warranted that such information and interpretation cannot be superseded by future geotechnical engineering developments. We emphasize that this report is valid for the project outlined above and should not be used for any other sites.

APPENDIX A

FIELD AND LABORATORY INVESTIGATIONS
Field Investigation
Appendix A
Page A.I
The field investigation consisted of a surface reconnaissance and a subsurface exploratory program.

Four 4½-inch to 6½-inch diameter exploratory borings were advanced. The boring locations are shown on the site plan.

The soils encountered were logged in the field during the exploration and with supplementary laboratory test data are described in accordance with the Unified Soil Classification System.

Modified standard penetration tests and standard penetration tests were performed at selected depths.

These tests represent the resistance to driving a 2½-inch and 1 ½-inch diameter split barrel sampler, respectively. The driving energy was provided by a hammer weighing 140 pounds falling 30 inches.

Relatively undisturbed soil samples were obtained while performing this test. Bag samples of the disturbed soil were obtained from the auger cuttings. The modified standard penetration tests are identified in the sample type on the boring logs with a full shaded in block. The standard penetration tests are identified in the sample type on the boring logs with half of the block shaded. All samples were returned to our Clovis laboratory for evaluation.

Laboraton Investigation
The laboratory investigation was programmed to determine the physical and mechanical properties of the foundation soil underlying the site. Test results were used as criteria for determining the engineering suitability of the surface and subsurface materials encountered.

In-situ moisture content, dry density, consolidation, direct shear and sieve analysis tests were completed for the undisturbed samples representative of the subsurface material. Atterberg limits, expansion index and R-value tests were completed for select bag samples obtained from the auger cuttings. These tests, supplemented by visual observation, comprised the basis for our evaluation of the site material.

The logs of the exploratory borings and laboratory determinations are presented in this Appendix.

APPENDIXB

EARTHWORK SPECIFICATIONS

GENERAL
AppendixB
Page B.1
When the text of the report conflicts with the general specifications m this appendix, the recommendations in the report have precedence.

SCOPE OF WORK: These specifications and applicable plans pertain to and include all earthwork associated with the site rough grading, including but not limited to the furnishing of all labor, tools, and equipment necessary for site clearing and grubbing, stripping, preparation of foundation materials for receiving fill, excavation, processing, placement and compaction of fill and backfill materials to the lines and grades shown on the project grading plans, and disposal of excess materials.

PERFORMANCE: · The Contractor shall be responsible for the satisfactory completion of all earthwork in accordance with the project plans and specifications. This work shall be inspected and tested by a representative of Krazan and Associates, Inc., hereinafter known as the Soils Engineer and/or Testing Agency. Attainment of design grades when achieved shall be certified by the project Civil Engineer.

Both the Soils Engineer and the Civil Engineer are the Owner's representatives. If the Contractor should fail to meet the technical or design requirements embodied in this document and on the applicable plans, he shall make the necessary readjustments until all work is deemed satisfactory as determined by both the Soils Engineer and the Civil Engineer. No deviation from these specifications shall be made except upon written approval of the Soils Engineer, Civil Engineer or project Architect.

No earthwork shall be performed without the physical presence or approval of the Soils Engineer. The Contractor shall notify the Soils Engineer at least 2 working days prior to the commencement of any aspect of the site earthwork.

The Contractor agrees that he shall assume sole and complete responsibility for job site conditions during the course of construction of this project, including safety of all persons and property; that this requirement shall apply continuously and not be limited to normal working hours; and that the Contractor shall defend, indemnify and hold the Owner and the Engineers harmless from any and all liability, real or alleged, in connection with the performance of work on this project, except for liability arising from the sole negligence of the Owner or the Engineers.

TECHNICAL REQUIREMENTS: All compacted materials shall be densified to a density not less than 90 percent relative compaction based on ASTM Test Method D1557 or CAL-216, as specified in the technical portion of the Soil Engineer's report. The location and frequency of field density tests shall be as determined by the Soils Engineer. The results of these tests and compliance with these specifications shall be the basis upon which satisfactory completion of work will be judged by the Soils Engineer.

SOILS AND FOUNDATION CONDITIONS: The Contractor is presumed to have visited the site and to have familiarized himself with existing site conditions and the contents of the data presented in the soil report.

The Contractor shall make his own interpretation of the data contained in said report, and the Contractor shall not be relieved of liability under the Contract documents for any loss sustained as a result of any variance between conditions indicated by or deduced from said report and the actual conditions encountered during the progress of the work.

DUST CONTROL: The work includes dust control as required for the alleviation or prevention of any dust nuisance on or about the site or the borrow area, or off-site if caused by the Contractor's operation either during the performance of the earthwork or resulting from the conditions in which the Contractor leaves the site. The Contractor shall assume all liability, including court costs of codefendants, for all claims related to dust or windblown materials attributable to his work.

SITE PREPARATION
Site preparation shall consist of site clearing and grubbing and the preparations of foundation materials for receiving fill.

CLEARING AND GRUBBING: The Contractor shall accept the site in this present condition and shall demolish and/or remove from the area of designated project earthwork all structures, both surface and subsurface, trees, brush, roots, debris, organic matter, and all other matter determined by the Soils Engineer to be deleterious or otherwise unsuitable. Such materials shall become the property of the Contractor and shall be removed from the site.

Tree root systems in proposed building areas should be removed to a minimum depth of 3 feet and to such an extent which would permit removal of all roots larger than 1 inch. Tree roots removed in parking areas may be limited to the upper 1 ½ feet of the ground surface. Backfill of tree root excavations should not be permitted until all exposed surfaces have been inspected and the Soils Engineer is present for the proper control of backfill placement and compaction. Burning in areas which are to receive fill materials shall not be permitted.

EXECUTIVE SUMMARY
The Property is located on the northwest side of Distel Circle, southwest of the intersection with El Camino Real, in the City of Los Altos, Santa Clara County, California. The Property consists of a rectangular-shaped parcel of approximately 36,450 square feet in size, which is improved with a one-story commercial office building, approximately 12,120 square feet in size, with associated asphalt paved parking and areas of maintained landscaping. According to the Property profile, the building was constructed in 1975. The Property is legally described as Assessor’s Parcel Number 51 of Assessor’s Map Book 170, Page 4 (APN 170-04-051).

The subject Property is occupied by Midpensinula Regional Open Space District. The Property is located in an area comprised of commercial usage southwest of El Camino Real, with commercial usage on adjoining streets. The Property and vicinity slope gently towards the northeast. None of the adjacent properties are considered to be of significant environmental concern to the Property.

On August 19, 2021, PIERS conducted a visual reconnaissance of the Property. PIERS inspected all exterior areas of the Property but did not enter any residences due to current environmental concerns (Covid-19) during the site reconnaissance.

The Property building occupies the western side of the parcel with other exterior areas including concrete paved walkways, a patio, asphalt paved parking on the eastern portion and areas of maintained landscaping.

The interior of the Property building includes offices, a lobby, kitchen, meeting rooms, storage rooms and bathrooms.

No hazardous materials or other chemicals were observed at the Property except for cleaning supplies and paints observed a storage room. All of these materials were observed to be stored correctly, and there was no evidence of any improper storage, usage, or disposal of hazardous materials or other chemicals.

No evidence of water supply, irrigation, oil, injection, or dry wells was observed on the Property.

No storage tanks were observed at the Property. No stained soil was observed. No significant staining was observed on the exterior paved surfaces.

No drains, sumps or clarifiers were observed.

Building department records included various permits related to the interior remodel work, reroofing, and a fire hydrant replacement in the sidewalk. No other local agency files were found.

The Property is listed sixteen times on the HAZNET database in the attached IHMRR as Midpeninsula Regional Open Space District for disposal of 0.2 ton of other organic solids in 2006, 0.17 ton of unspecified oil-containing waste in 2009, and 0.005 ton of inorganic solid waste and Polychlorinated biphenyls (PCBs) in 2011; as US Army Corps of Engineers for disposal of 0.02 ton of other organic solids in 2007 and 6.25 tons of unspecified oil-containing waste in 2008; and as Almaden Air Force Station for disposal of 45.08 tons of PCBs in 2008. 607
Agenda Item # 10.

Phase I ESA Report August 2021
330 Distel Circle, Los Altos, CA Page 2
The HAZNET status for Midpeninsula is inactive in 2000, 2006, 2011 and 2013; for US ACE, inactive in 2007 and 2008; and for Almaden AFS, inactive in 2009.

The adjacent parcel to the south at 370 Distel Circle, is listed on the HAZNET database as Sutter Bay Medical Foundation (active as of 2020) for the removal and disposal of pharmaceutical waste in 2019, and as Palo Alto Medical Foundation (inactive in 2016) for the disposal of photochemicals/photoprocessing waste, oxygenated solvents and asbestos containing waste from 1994 to 2004; the site does not appear to be of significant environmental concern to the Property.

The adjacent parcel to the north at 5000 W. El Camino Real is listed twice on the ERNS database for 130 gallons of mineral oil released from an electric pad mounted transformer due to external corrosion – no PCBs were released – in 2004; the release was removed by soil excavation and the equipment was repaired.

Based on historical research conducted using aerial photographs, in 1948, the Property was occupied by orchards, as is the surrounding area, except for scattered rural residences. El Camino Real bounds the Property to the northeast.

On the 1956, 1960 and 1968 aerial photographs, the Property has been cleared of orchard trees.

On the 1980 and later aerial photographs, the Property appears developed with the current building and associated parking lot. The adjacent and vicinity appear largely developed from 1987 onwards. No features of obvious environmental concern were identified at the Property or vicinity on any of the aerial photographs reviewed.

The prior use of the Property for agriculture implies the use of agricultural chemicals such as fertilizers and pesticides. However, former use of agricultural chemicals is considered de minimis under ASTM E1527-13. Fertilizers and pesticides tend to biodegrade over time and the last likely use of agricultural chemicals was prior to the development of the Property in 1956, nearly 65 years ago. Additionally, subsurface migration of agricultural chemicals tends to be low, and surface soils were likely removed during development of the Property. Therefore, the Property’s former use as an orchard is not likely to pose significant environmental risk to human health or the environment.

Based on city directory listings and local building department records, the Property was occupied by various commercial tenants from 1980 to 2017. No listings of environmental concern were identified. No other uses are known.

No sites with VOC contamination were identified within the critical distances cited in the VES guidance document. Therefore, it is unlikely that a VEC exists on or near the subject Property. 608

FINDINGS AND OPINIONS
This assessment has revealed no evidence of Recognized Environmental Conditions (REC), Historical Recognized Environmental Conditions (HRECs) or Controlled Recognized Environmental Conditions (CRECs) associated with the subject Property.

An environmental issue is defined as an environmental concern which does not qualify as a REC, but which may warrant further discussion. PIERS did not identify any environmental issues during this Phase I ESA.

CONCLUSIONS AND RECOMMENDATIONS
This Phase I ESA has revealed no evidence of Recognized Environmental Conditions (RECs) or environmental issues in connection with the subject Property or adjacent properties. PIERS recommends no further investigation of the Property at this time. 609

INTRODUCTION

PROPERTY
PIERS Environmental Services, Inc. (PIERS) has completed this Phase I Environmental Site Assessment (ESA) for the property located at 330 Distel Circle, in the City of Los Altos, Santa Clara County, California (cited hereafter as the Property). PIERS was retained by Mr. Steve Pratt of EAH Housing (cited hereafter as the Client) to conduct this Phase I Environmental Site Assessment for the subject Property for the purpose of compliance with the “All Appropriate Inquiries” Final Rule (40 CFR Part 312) under CERCLA (42 USC 9601). This report follows the guidelines as stated in ASTM Standard Designation E1527-13: Standard Practice for Environmental Site Assessments:

Phase I Environmental Site Assessment Process. This Standard complies with “All Appropriate Inquiries” (AAI) 40 CFR Part 312. Any exceptions to, or deletions from, this practice are described in the Deviations Section of this report.

PURPOSE
The purpose is to conduct a Phase I Environmental Site Assessment (Phase I ESA) on this parcel of commercial real estate at 330 Distel Circle, Los Altos, CA with respect to the range of contaminants within the scope of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) (42 USC 9601) and petroleum products. This practice (ASTM E1527-13) is intended to permit a user, (i.e. Property owner, buyer, seller, or the Client) to satisfy one of the requirements to qualify for the innocent landowner, contiguous property owner or bona fide prospective purchaser limitation on CERCLA liability (hereinafter, the “landowner liability protections,” or “LLPs”) as defined under 42 USC 9601(35)(B).

The goal of the Phase I ESA is to identify recognized environmental conditions (RECs); historical RECs (HREC); or Controlled RECs (CREC). RECs are defined as the presence or likely presence of any hazardous substances or petroleum products, in, on or at a property due to release to the environment; under conditions indicative of a release to the environment or under conditions that pose a material threat of a future release. De minimis conditions are not recognized environmental conditions. HRECS are defined as the historical presence or likely presence at a property of any hazardous substances or petroleum products which were remediated or had undergone risk-based cleanup to meet unrestricted land use criteria. CRECs are defined as past releases of hazardous substances or petroleum products at a property that were addressed with risk-based closures, but contaminants are allowed to remain in place subject to the implementation of required activity and use limitations (AULs), for example, institutional controls or engineering controls.

De minimis conditions are defined as a condition that generally does not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. 610
Agenda Item # 10.

Phase I ESA Report August 2021
330 Distel Circle, Los Altos, CA Page 5
The identification of potential or existing RECs, HRECs, and/or CRECs affecting the Property is to determine if it:
 Constitutes or results in a potential or material violation of any applicable environmental laws;
 Imposes any material constraints of the operations of the Property or requires a material change in the use thereof (i.e. institutional controls/deed restrictions);  Requires remedial actions or other responses with respect to hazardous substances or petroleum products affecting the Property under any applicable environmental law;
 May affect the value of the Property; and
 May require specific actions to be performed with regard to such conditions and circumstances.

The Client may use the information contained in this Phase I ESA report for the purposes of:
 Evaluating the Client’s legal and financial liabilities for transactions related to purchase, sale, loans, seller financing, or foreclosure of the Property;  Evaluating the Property’s overall development potential, associated market value and the impact of applicable laws that restrict financial or other types of assistance for Property development; and/or
 Determining if specific actions are required prior to the purchase, sale, loan, financing or foreclosure of the Property.

SCOPE OF WORK
The Scope of Services for the performance of this Phase I ESA included the following tasks:
 On-site visual reconnaissance of the Property to evaluate on-site activities in respect to hazardous materials use, storage and disposal activities.  On-site visual survey of the current uses of the immediately adjacent sites, and surrounding area.
 Review of selected historic documentation for the Property to determine what activities have occurred at the subject site since the Property’s first developed use.  Review of reasonably ascertainable regulatory agency files concerning hazardous material use, storage and disposal at the Property and at adjacent and surrounding sites.
 Acquisition and detailed professional review of a current environmental sites radius report (PIERS Identified Hazardous Materials Sites Radius Report [IHMSRR]).
 Preparation of this report in general accordance with the document entitled Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process (The American Society for Testing and Materials [ASTM], Designation E 1527-13) and “All Appropriate Inquiries” Final Rule, 40 Code of Federal Regulations (CFR) Part 312.
 Interviews with available Property contacts, regulatory officials and personnel associated with the subject and adjoining properties.

To achieve the study objectives for this project PIERS was required to base conclusions and recommendations on the best information available during the period the investigation was conducted. PIERS professional services are performed using the degree of care and skill ordinarily exercised by environmental consultants practicing in this or similar fields. The findings are mainly based upon examination of historic records, maps, aerial photographs, and governmental agencies lists. It should be noted that governmental agencies often do not list all sites with environmental contamination; the lists and data used could be inaccurate and/or incomplete. Recommendations are based on the historic land use of the subject Property, as well as features noted during the site inspection. The absence of potential gross contamination sources, historic or present, does not necessarily imply that the subject Property is free of any contamination.

This project did not include sampling of materials (for example: soil, water, air, mold, building materials). This Phase I ESA does not include the mention of, recovery, sampling, or reporting of the nature or extent of Asbestos Containing Materials or any mold issues. PIERS does not warrant or guarantee that no significant events, releases or conditions could have arisen during the periods with data gaps (if they exist).

This Phase I ESA does not include information or advice relating to any environmental issues, laws or environmentally related business decisions that have not been stated in the above outline. No warranties, therefore, are expressed or implied. PIERS has no liability towards consequential damages. In some cases, an environmental compliance audit may be necessary for a Property. The information and opinions rendered in the report are exclusively for use by the Client.

RECORDS REVIEW

PHYSICAL SETTING SOURCES

TOPOGRAPHIC MAP REVIEW
The Property is located at an elevation of approximately 80 feet above mean sea level (U. S. Geological Survey 7.5 Minute Topographic Quadrangle, “Mountain View”). The Property is located within an area that is relatively flat. Regionally, the area slopes towards the north-northeast.

HYDROGEOLOGICAL REVIEW
The direction of groundwater flow in the vicinity of the Property is inferred to be to the north-northeast, consistent with the topography.

According to Helley et al (1979), the Property and vicinity are underlain by Late Pleistocene alluvium (Qpa). These sediments are described as weakly consolidated, slightly weathered, poorly sorted irregular interbedded clay, silt, sand and gravel that is at least 150 feet thick. This material grades progressively from coarse-grained stream deposits toward higher elevations to fine-grained alluvial fan and fresh-water marsh deposits nearest the present shore of the bay.

Based on information obtained online from the USDA Natural Resources Conservation Service Web Soil Survey database, the Property is mapped as Urban Land – Flaskan Complex. These soils include sandy loams, sandy clayey loams, gravelly sandy clayey loams and very gravelly sandy loams in alluvial fan settings. The soils are well drained with low runoff, non-saline to very slightly saline, and generally have a depth to water table of more than 80 inches.

A Request for Case Closure, dated March 11, 2013, for a nearby Leaking Underground Storage Tank (LUST) case site, at 895 North San Antonio Road, measured depths to groundwater of between 28.48 feet to 42.51 feet below ground surface (bgs), with a groundwater flow direction towards the northwest. The inferred groundwater flow direction in the vicinity is to the northwest.

REGULATORY AGENCIES DATABASES REVIEW
Attached to this report as Appendix C is a PIERS Identified Hazardous Materials Sites Radius Report (IHMSRR) for the subject Property. The report identifies sites of environmental concern within a one-mile radius of the subject Property.

The databases searched to compile the enclosed report are gathered from numerous federal, state and local governing environmental entities. All of the databases required to be searched by ASTM E1527-13 – Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process – Section 8.2.1 Standard Federal, State, and Tribal Environmental Record Sources have been included in this report, and searched to the required distances from the subject Property. The following is an analysis of the attached report.

SUMMARY OF DATABASES REVIEWED:

SUBJECT PROPERTY
The Property is listed sixteen times on the HAZNET database in the attached IHMRR as Midpeninsula Regional Open Space District for disposal of 0.2 ton of other organic solids in 2006, 0.17 ton of unspecified oil-containing waste in 2009, and 0.005 ton of inorganic solid waste and Polychlorinated biphenyls (PCBs) in 2011; as US Army Corps of Engineers for disposal of 0.02 ton of other organic solids in 2007 and 6.25 tons of unspecified oil-containing waste in 2008; and as Almaden Air Force Station for disposal of 45.08 tons of PCBs in 2008. The HAZNET status for Midpeninsula is inactive in 2000, 2006, 2011 and 2013; for US ACE, inactive in 2007 and 2008; and for Almaden AFS, inactive in 2009.

The Property is not listed on any of the other regulatory agency databases summarized in the attached IHMRR. No spills or releases were noted for the site.

SURROUNDING SITES

NPL - NATIONAL PRIORITIES LIST/TRIBAL NPL
One site within a one-mile radius from the Property were listed on the National Priority List (NPL) database. No sites were listed on the Proposed NPL database, Delisted NPL database or on a Tribal NPL database. The Jasco Chemical Corp is located approximately 4,804 feet east from the Property. As the inferred groundwater flow direction is to the northwest, the site is considered to be in the cross-gradient direction, and as such, does not appear to be of significant environmental concern to the Property.

CORRACT
No sites within a one-mile radius from the Property were listed on the CORRACT database.

Phase I ESA Report August 2021
330 Distel Circle, Los Altos, CA Page 18
TSD
Twenty-three sites within a one-mile radius from the Property were listed on the TSD database. Twenty sites are located between approximately 650 feet south west to 5,150 feet north east from the Property, cross-gradient to down-gradient, and as such, do not appear to be of significant environmental concern to the Property.

Two sites are located approximately 1,586 feet southeast and 3,283 feet southeast from the Property, up-gradient. Based on the distances of these sites from the Property, the risk to the groundwater beneath the Property from these potential sources appears low.

DEFENSE
No sites within a one-mile radius from the Property were listed on the DEFENSE sites database.

BROWN
No sites within a one-mile radius from the Property were listed on the BROWNFIELDS sites database.

CSL
Thirty sites within a one-mile radius from the Property were listed on the CSL database. Some sites have multiple listings. Eighteen sites are closed cases, certified cases or in verification monitoring, and therefore do not appear to be of significant environmental concern to the Property.

Twelve open case sites (some sites are listed twice) are located between approximately 2,716 feet north and 4,795 feet east, cross-gradient or downgradient from the Property, and as such, do not appear to be of significant environmental concern to the Property.

DEED
Two sites within a one-mile radius from the Property were listed on the DEED database. The sites are located approximately 2,882 feet northeast and 2,891 feet northeast, cross-gradient, and as such, do not appear to be of significant environmental concern to the Property.

SUPERFUND
No sites within a one-half mile radius from the Property was listed on the SUPERFUND database.

U.S. INSTITUTIONAL AND ENGINEERING CONTROL

REGISTRIES/TRIBAL
No sites within a one-half mile radius from the Property were listed on the federal institutional control/engineering control registries database. No sites within a one-half mile radius from the Property were listed on a tribal institutional control/engineering control registries database.

LUST/ TRIBAL LUST
Ten sites within a one-half mile radius from the Property were listed on the LUST database. Some sites have multiple listings. Some of the cases are closed.

In fuel leak cases, research conducted in the State of California by Lawrence Livermore National Laboratory (LLNL) indicates that attenuation and degradation of the product in groundwater play major roles in reducing the hydrocarbon contamination to non-detectable levels within several hundred feet of the contaminant source. Moreover, this research indicates that in over 90% of the hydrocarbon contamination cases, with the possible exception of MTBE or other fuel oxygenates, groundwater contaminant plumes do not extend more than 250 feet from the source. Solvent/toxic contamination plumes may extend farther from the source.

Based on the discussion above, fuel leak LUST sites that are within one-eighth mile in the up-gradient direction, and up-gradient solvent or toxic leak sites are considered to have potential risk to the subsurface soils and/or groundwater of the Property.

Two LUST sites (one site, listed twice) within one-eighth mile of the Property were listed. The site was listed as case closed in 1996, and therefore does not appear to be of environmental concern to the Property.

SWLF/ TRIBAL SWLF

No sites within a one-half mile radius from the Property were listed on the SWLF database or a Tribal SWLF database.

WELLS
No sites within a one-quarter mile radius from the Property were listed on the WELLS database.

HAZMAT
Twelve sites within a one-quarter mile radius from the Property were listed on the HAZMAT database. Neither the Property nor any other adjacent parcels were listed on the HAZMAT database.
625
Agenda Item # 10.

Phase I ESA Report August 2021
330 Distel Circle, Los Altos, CA Page 20
All of the sites are located over 510 feet from the Property. These sites would only be of potential environmental concern where they are located up-gradient and are listed on other agency databases as having had unauthorized releases or spills, in which case they are discussed under the agency-listed heading.

ERNS
The adjacent parcel to the north at 5000 W. El Camino Real is listed twice on the ERNS database for the release of 130 gallons of mineral oil from an electric pad mounted transformer due to external corrosion – no PCBs were released – in 2004; the release was removed by soil excavation and the equipment was repaired. The site is located 175 feet northwest, down-gradient, and therefore does not appear to be of environmental concern to the Property. Neither the Property nor any other adjacent parcels were listed on the ERNS database.

GENERATORS
The adjacent parcel to the south at 370 Distel Circle was listed on the GENERATORS database (4 listings) for being a small quantity generator of pharmaceutical waste with no violations. The site does not appear to be of significant environmental concern to the Property. Neither the Property nor any other adjacent parcels were listed on the GENERATORS database.

UST/TRIBAL UST
No sites within one-eighth mile of the Property were listed on the UST database.

No sites were listed on the Tribal UST database.

AST/TRIBAL AST
No sites within one-eighth mile of the Property were listed on the AST database.

No sites were listed on the Tribal AST database.

AIR EMISSIONS
No sites within one-eighth mile of the Property were listed on the Air Emissions database.

HAZNET
Seventy-four sites within one-eighth mile of the Property are listed on the HAZNET database. The Property is listed (16 listings) and discussed above. The adjacent parcel to the south at 370 Distel Circle is listed twice each for Sutter Bay Medical Foundation for the removal and disposal of pharmaceutical waste in 2019 (active as of 2020); and Palo Alto Medical Foundation for the disposal of photochemicals/photoprocessing waste, oxygenated solvents and asbestos containing waste from 1994 to 2004, and is not active at this time. No other adjacent parcels were listed on the HAZNET database.
626
Agenda Item # 10.

Phase I ESA Report August 2021
330 Distel Circle, Los Altos, CA Page 21
All of the remaining sites are located over 126 feet from the Property. These sites would only be of potential environmental concern where they are located upgradient and are listed on other agency databases as having had unauthorized releases or spills, in which case they are discussed under the agency-listed heading.

HISTORICAL USE INFORMATION
As described under ASTM E1527-13 – Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process – Section 8.3 Historical Use Information, Historical Use Information is the objective of consulting historical records sources to develop a history of the previous uses of the Property and surrounding area in order to identify the likelihood of past uses having led to recognized environmental conditions in connection with the Property. All obvious uses of the Property shall be identified from the present back to the Property’s first developed use or back to 1940 whichever is earlier.

Sources of such information are typically: interviews, aerial photographs, Sanborn Fire Insurance (Sanborn) Maps, city directories, and local fire, building and health department files. Other historical sources include internet sites, community organizations, local libraries and historical societies, and current owner/occupants of neighboring properties. Historical research documentation is attached to this report as Appendix D.

SANBORN FIRE INSURANCE MAPS REVIEW
No historical Sanborn Fire Insurance Map coverage of the Property or vicinity was found.

LOCAL CITY DIRECTORY REVIEW
City Directories have been published for major cities and towns across the United States since the 18th century. Originally, these Directories, published in the 20th century, also included a street index. For each street address, the Directory lists the name of the resident or business operating from this address during a given year. City Directories are a valuable source of historical information with regard to site tenancy and use. Directories for rural areas were not often published.

PIERS reviewed The EDR – City Directory Image Report. Available directories for the period of 1973 through 2017 were reviewed, as follows:

HISTORICAL AERIAL PHOTOGRAPH REVIEW
PIERS reviewed available aerial photographs from the NETR online database were reviewed for evidence of hazardous materials and features that may have impacted the Property. Aerial photographs from 1948, 1956, 1960, 1968, 1980, 1987, 1991, 1993, 1998, 2002, 2004, 2005, 2012, 2014 and 2016 were reviewed.

On the 1948 aerial photograph, the Property is occupied by orchards, as is the surrounding area, except for scattered rural residences. El Camino Real bounds the Property to the northeast.

On the 1956, 1960 and 1968 aerial photographs, the Property has been cleared of orchard trees. Two parcels to the north appear developed with residential structures. The surrounding area is similar, gradually becoming more developed during this period.

On the 1980 and later aerial photographs, the Property appears developed with the current building and associated parking lot. The adjacent and vicinity appear largely developed from 1987 onwards.

No features of obvious environmental concern were identified at the Property or vicinity on any of the aerial photographs reviewed.

The prior use of the Property for agriculture implies the use of agricultural chemicals such as fertilizers and pesticides. However, former use of agricultural chemicals is considered de minimis under ASTM E1527-13. Fertilizers and pesticides tend to biodegrade over time and the last likely use of agricultural chemicals was prior to the development of the Property in 1975, nearly 46 years ago. Additionally, subsurface migration of agricultural chemicals tends to be low, and surface soils were likely removed during development of the Property.

Therefore, the Property’s former use as an orchard is not likely to pose significant environmental risk to human health or the environment.

VAPOR ENCROACHMENT SCREENING
The Vapor Encroachment Screening (VES) Standard (ASTM E2600-10) may include a twotiered screening process. Initially, the Tier 1 VES focuses on known or suspected contaminated properties located within the area of concern (AOC). According to ASTM E2600-10:
“the AOC is one third of a mile around the TP [Target Property], unless the use of a shorter distance (such as for petroleum hydrocarbon constituents of concern [COCs]) is appropriate. The AOC is measured from the TP to a contaminated property with known or suspect COC contamination of soil or groundwater or both.” “If there are known or suspect property sources of contamination within the AOC, the environmental professional should evaluate whether COC may be present at the TP. “For a contaminated property identified in Tier 1 located cross-gradient from the TP, the AOC will be the area within the critical distance plus one half of a reasonable estimation of the contaminated plume width (at the point nearest the closest TP boundary) that might be associated with the nearby known or suspect contaminated property (that is, the contaminated property where the groundwater contamination originated).” ASTM E2600-10 states that if a VEC cannot be ruled out in the Tier 1 screen, the user can undertake more refined screening, as provided in Tier 2. “Tier 2 applies numeric screening criteria to existing or newly collected soil, soil gas, and/or groundwater testing results to evaluate whether or not a VEC can be ruled out. Tier 2 has two data collection components: one non-invasive and one invasive.

The objective of the non-invasive Tier 2 process is to identify through documentation, information regarding plume lengths and contaminants, remediation status, etc. The noninvasive Tier 2 VES uses a plume test and critical distance determination to evaluate whether vapors from the contaminated property might migrate to and encroach upon the Target Property.

The critical distance between the Target Property and a contaminated plume is defined by E2600-10 as 30 feet (9 meters) for dissolved petroleum hydrocarbons, and 100 feet (30.5 meters) for separate-phase product petroleum hydrocarbons and non-petroleum chemicals of concern (“COCs”) such as volatile organic compounds (VOCs). Contaminated groundwater plumes within these distances may constitute a VEC to the Target Property.

The User should be aware that:
 The presence of a VEC does not necessarily constitute a REC. The EP is to determine if the VEC represents a REC for the Target Property.
 The VES process does not evaluate the potential for vapor intrusion (VI) of subsurface vapors into existing buildings. Evaluation of VI conditions requires field sampling, and is not included in ASTM E1527-13.

EVALUATION
No sites with VOC contamination were identified within the critical distances cited in the VES guidance document. Therefore, it is unlikely that a VEC exists on or near the subject Property. 630

IDENTIFIED HAZARDOUS MATERIALS SITES RADIUS REPORT

TABLE OF CONTENTS

Agenda Item # 10.

The databases searched to compile the enclosed report are gathered from numerous federal, state and local governing environmental entities. All of the databases required to be searched by ASTM Standard E 1527 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process "Standard Environmental Records Sources" have been included in this report, and searched to the required distances from the subject property. Additionally, Cypress Technology Solutions, Inc (CTS) has acquired other valuable databases and integrated them into the Cypress STARReport System in order to provide more valuable information to our clients regarding hazardous materials storage and release sites within a onemile radius from the subject property.

CTS has created a sophisticated data update system, keeping our report databases as current as possible (surpassing ASTM E1527 requirements). CTS consistently requests and updates data from each of the government agencies used to create this report. Depending on the type of database, records are updated at the agencies at varying intervals (daily, monthly, quarterly, semiannually, or annually). An overall data update (including all available updates) is loaded into our specialized software on a quarterly basis. It should be clearly understood that this database/map report lists only reported and accurately entered sites. Numerous sites have yet to be discovered and therefore are not yet listed by any governmental agency. The most effective way to determine if a site may be listed by a government agency in the future is by performing a Transaction Screen or Phase I Environmental Site Assessment, which include a professional site inspection and review of historical records. This radius report satisfies only one subsection requirement found within the ASTM Phase I Environmental Site Assessment reporting requirements. This report should not be considered a Phase I Environmental Site Assessment. If no sites are found for a database searched, the database and its description are excluded from the report details so as to report recorded sites only. Sites that include erroneous or incomplete address information may not show up on the report. Every attempt is made to include a listing of these unlocated sites in the report where there is a possibility of their impacting the subject property, but no guaranty can be made.

CTS has used a technology called Geocoding to locate the sites on the map. While this technology is the standard of care in the industry and is generally reliable for well formatted, complete and correct addresses, due to the limitations of this technology no guaranty of the accuracy of site placement can be made.

For specific data inquiries or interpretations, environmental consultation, or to order Transaction Screen Reports, Phase I Environmental Site Assessment Reports, or other environmental reports, please contact us via email at [email protected], or via telephone at 4085591248. A full summary of our firm, including services offered and pricing can be viewed at www.pierses.com.

DISCLAIMER
This report contains data obtained from multiple governmental agencies. Neither CTS nor PIERS can insure the accuracy of the enclosed information. CTS and PIERS are in no way responsible for errors and/or omissions occurring in data, data conversion, or for the client's use of the information (report). CTS, PIERS and its affiliates cannot be held liable for accuracy, storage, loss or expense suffered by customers resulting directly or indirectly from any data provided by CTS. No warranty expressed or implied is made in any way in connection with this report.

CTS has researched and obtained certain local, State and Federal environmental databases (Data) to assist its client's in meeting the requirements of ASTM Standards. CTS has obtained Data that is readily available and of adequate quality to be included in this report. As of the date of this report, there are certain Data that are either not yet available or are not of adequate quality and therefore are not included in this Report. 21215 1

spaces. There was a release of tetrachloroethene
(PCE), a solvent used in dry cleaning, to soil and
groundwater. Only low levels of PCE were found
in soil. Elevated levels of PCE were found in
groundwater and a groundwater extraction and
treatment system was installed and operated to
cleanup groundwater. The extraction and
treatment system was shut down when it was no
longer significantly reducing PCE levels in
groundwater.

Site His to r y No Water Board oversight of cleanup at this site.

This case is included in Geotracker because the
site is covered by the Water Boards NPDES
general permits for discharges from pump and
treat systems to surface waters (one each for
fuels- and VOC-impacted sites). This can
happen for two reasons: (i) the site is overseen
by another agency (e.g., USEPA or DTSC) and
needs coverage under one of the NPDES general
permits or (ii) construction dewatering in an
area of groundwater contamination necessitates
NPDES general permit coverage. Including this
case in Geotracker helps staff to receive and
review required NPDES reports. The Water
Board issued a Notice of Termination for this
facility on November 3, 2009.

2nd floor. Elevator maintenance company came
out and added oil to the system and did not note
a leak at that time. The release was reported to
OES on 4/18/11. In May, the elevator jack was
