Subject : Notice of Receipt of Petition for Cancellation of Land Conservation Contract
No. 75-913 (Santa Clara Recorder's Office Document #4954827) and
Preliminary Evaluation of the Required Five Consistency Findings
Dear Mr. Bunn,
Pursuant to Government Code Section 51284.1 (a), we are sending you this Petition for
Cancellation of Williamson Act Contract No. 75 -913 (Santa Clara Recorder's Office Do c ument
#4954827) for your review and comment. Enclosed are petition materials submitted by the
current landowners, Surrey Farms Group, LLC (Linda Ramsbottom), Walter-Robert, LLC (Larry
Dodge), and Twin Oaks Hike, LLC (Tom Dodge), for removal of an approximately 17.8-acre
parcel from the Williamson Act program.
The applicant is petitioning for cancellation of the contract in order to subdivide the 17.55 -acre
site into 12 lots for future development of 10 new single-family residences (plus one lot for
private streets, and one open space lot).
The following information is provided to as si st you in your evaluation of the petition and in
providing comments.
Soil Classifi cation : Oth er Land
Water Availability: Water service would be provided by the San Jose Water Company. Eight-
inch water lines would be extended along the proposed Private Streets, connecting with
ex isting water lines i n Twin Oak s Drive at the western project boundary, Brooke Acre s Drive at
the southern boundary, and Cerro Vi sta Court at the northern project boundary.
Farming History: The si t e wa s u sed for orchard s in th e 1930s (and pos sibly the 1940s), but the
orcha r d s were removed by 1948. Th e site does not appe ar to have been in agricultural use
since that tim e. The surrounding properties are all d eveloped with single family homes, w ith
the exception of the Hillbrook School, an elementary sc hool which shares a portion of th e
property's northern boundary.

Petition Documents: Al so included for your review, are documents provided by the applicant
and related to the cancellation process such as the petition for cancellation, a copy of Land
Conservation Contract No. 75-913 (Santa Clara Recorder's Office Document #4954827), a copy
of the recorded notice of non-renewal, findings prepared by the applicant, an area map, a
biological memo, current market value estimate, and a shallow soil sampling report.
Town Staff Evaluation : Below is our preliminary evaluation of the five required Consistency
findings for cancellation of Land Conservation Contract No . 75-913 (Santa Clara Recorder's
Office Document #4954827). This preliminary analysis is based on evaluating the proposed
alternate use against the General Plan policies that would apply if the proposed zoning and
General Plan designation were approved, as well as addressing the five Consistency findings
from Town staff's perspective.
1. That the cancellation is for land on wh ich a Notice of Non renewal has been served,
pursuant to Section 51245 of the Government Code.
A Notice of Nonrenewal for the 17.8-acre property was accepted by the Town on April
28, 2015, and recorded by the County Recorder on October 31, 2017, and was assigned
Document No. 23789473.
Based on the fact stated above, staff believes that Finding No. 1 can be made.
2. That the cancellation is not likely to result in the removal of adjacent lands from
agricultural use .
None of the adjacent lands are under agricultural use or zone, therefore staff does not
believe that removal of the 17.8-acre parcel from Contract restrictions will result in
removal of adjacent land from farming; therefore, staff believes this finding can be
made .
3 . That the cancellation is for an alternate use that is consistent with the provisions of the
Town's General Plan .
The 2020 General Plan Land Use Element designates the project site as Agriculture . In
1988, the Town Council adopted Resolution No . 1988-230, which required amendment
of the General Plan and Hillside Specific Plan designations to reflect rezoning of
properties subject to Williamson Act contracts . Therefore, as part of a subsequent
General Plan update, all Williamson Act lands were redesignated to Agriculture. Prior to
this redesignation, the project site was designated in the Town's 1961 General Plan as
Residential (Oto 2 families per acre). Since the Williamson Act contract is proposed to
be cancelled , the project site's General Plan designation will, once again, require
amendment pursuant to Resolution 1988-230 if the cancellation is approved .
2
The 2020 General Plan designates the area immediately west and southwest of the site
as Low Density Residential (Oto 5 units per acre), while contiguous areas to the north,
east, and southeast are designated as Hillside Residential (Oto 1 unit per acre). In
connection with this petition for cancellation the Town is processing an application to
change the General Plan Designation to Hillside Residential and rezone the property
from Resource Conservation to Hillside Residential (Oto 1 units per acre). At 0.57 unit
per acre, the proposed density would be consistent with the Hillside Residential
designation .
The Draft Environmental Impact Report for the project (available with other project
related documents online here: http ://www.losgatosca .gov/2390/T) includes the
following table of applicable General Plan Policies :

to protect the riparian habitat. See discussion below

conditions. Issues relating to taking "advantage of scenic

Goal CD -7: To preserve the quality of the
private open space throughout Los Gatos.
CD-7.1: Maximize quality usable open space
in all new developments.
Private open space associated with the 10 single-family
residences would be provided as yards and hillside on the
10 project lots. In addition, the project would provide to
the public approximately 3.6 acres of open space in the
southeast corner of the site and a pedestrian/ equestrian
trail that would provide an important connection/link
between the Shannon Road neighborhood with the
Kennedy Road neighborhood.
The soil of the subject parcel is classified as "Other Land " on the Santa Clara County
Important Farmland Map. This classification is land that is not included in any other
mapping category. Our understanding is that this category is given to this site because
of the site's size under 40 acres, its current vacant state, and the fact that it has urban
development on all sides.
Based on these facts, staff believes that the proposed alternate use is not
inconsistent with the Town's General Plan policies and therefore, believes Finding No. 3
can be made .
4. That the cancellation will not result in discontiguous patterns of urban development.
The surrounding parcels are located in a developed residential area of the Town of Los
Gatos. Zoning of adjacent properties include Single Family Residential (R-1) and Hillside
Residential (HR), including the Hillbrook School which shares part of the property's
northern boundary. No vacant, undeveloped, or agricultural lands are adjacent to the
subject property. Therefore, staff believes the proposed cancellation will not result in
discontiguous patterns of urban development .
Based on the facts stated above, staff believes Finding No . 4 can be made .
5. That there is no proximate, non-contracted land which is both available and suitable for
the use to which it is proposed that the contracted land be put, or that development of
the contracted land would provide more contiguous patterns of urban development
than development of proximate non-contracted land .
The applicant provided a map and a list identifying similar sized non-contracted parcels
within a 3-mile radius of the subject parcel, and addressed utilizing any of the non-
contracted parcels for the proposed use. The applicant included information on the
map regard ing the suitability of those parcels . Staff believes that the applicant has done
a reasonable search to find a non-contracted parcel that can be used for the alternate
use and therefore Finding No . 5 can be made.
We request that you send us your comments regarding the proposed cancellation within 30-
days from the receipt of this letter.

Findings for Cancellation of Williamson Act Contract
Surrey Farms, Los Gatos, CA
(APN 532-16-006)
Per section 51282(a) of the Government Code, a landowner may petition the Los Gatos Town
Council for cancellation of a Williamson Act Contract ("WAC") as to all or any part of the subject
land . The Town Council may grant tentative approval for cancellation of a WAC only if it makes
one of the following findings :
(1) That the WAC cancellation is consistent with the purposes of the W illiamson Act.
(2) That the WAC cancellation is in the public interest.
For purposes of Government Code section 51282(a)(1) cancellation of a WAC shall be
consistent with the purposes of the Williamson Act only if the Town Council makes all of the
following findings :
A. That the WAC cancellation is for land on which a notice of nonrenewal has been served
pursuant to Section 51245.
The notice of nonrenewal was filed and recorded on October 31 , 2017 (Document
#23789473) by the landowners and is consistent with the Williamson Act.
B . That the WAC cancellation will not result in the removal of adjacent lands from
agricultural use.
The subject property (APN 532-16-006) ("Property") is owned by Surrey Farms Estates,
LLC . The Property is surrounded by lands that are not designated prime agricultural
land and are not under WACs. Therefore, the cancellation is not likely to result in
removal of adjacent lands from agricultural use.
C . That the WAC cancellation is for a proposed alternative use, which is a single-family
residential subdivision that includes 10 single-family lots and one open space lot
("Project"). As discussed below, the Project is consistent with the applicable provisions
of the Town's General Plan and zoning.
Prior to entering into a WAC , the Property was designed for residential use at a density
higher than the Project's density . With the proposed cancellation of the WAC , the Project
is proposed to be developed with single-family residences at a density that is less than
or equal to adjacent residential densities. The Project's overall density of 0 .57 unit per
acre would be consistent with the proposed General Plan's density of O to 1 unit per acre
and lower than the density that was specified for the site in the 1961 General Plan (prior
to establishment of the WAC).
4828-5594 -1457v1
JH\23008001
1
The current General Plan Land Use E lement designation for the Property is "Agriculture"
and the zoning designation is RC (Resource Conservation) in Chapter 29 of the Los
Gatos Town Code. Single-family residential dwellings are permitted in the RC zoning
district. The Project will require a General Plan Amendment to Hillside Residential and
rezoning Hillside Residential (HR-1 . However, th is will be consistent with the General
Plan and zoning designation of adjacent lands. The re-designation of the Property to
Hillside Residential would be consistent with Policy LU-1 .5 of the General Plan, which
states that "Infill projects shall de designed in context with the neighborhood and
surrounding zoning with respect to the existing scale and character of surrounding
structures, and should blend rather than compete with the established character of the
area." Therefore rezoning of the Property would be considered consistent with the
Town's General Plan.
The Property is surrounded by hillside residential properties and one school property
and is considered to be an in-fill development. Adjacent lands to the west are zoned R-1-
10, whereby the minimum lot area is 10,000 sq . ft. Adjacent lands to the southwest , east
and north are zoned HR-1 whereby the minimum lot area is 1-5 acres.
The Project includes 10 single-family lots and one open space lot. Five lots are in the
vicinity of the existing R-1-10 zoned properties and range in size from 0 .94 acres
(40 ,912 sq . ft.) to .98 acres (42,648 sq . ft.). The remain ing 5 lots range from 1.03 acres
(44,698 sq . ft.) to 2 .67 (116,327 sq . ft .) that are adjacent to properties, which are zoned
HR-1 (minimum lot area is 1 -5 acres). The Project will include a 3 .32 acre open space
area. When compared to existing lots in the Project vicin ity, the Project lots would fall
within the range of lot sizes that surround the Project site with lower lots smaller and
upper lots larger, consistent with the lot size pattern that occurs in the immediate Project
vicinity. Therefore, the Project would protect the quality of life for surrounding residences
and blend with the established character of the area.
This price range property has been underserved from 2008 -2017. The draft 2015 -
2023 Housing element has identified a total of 174 "Above Moderate" income-housing
units required to meet the Regional Housing Needs Allocation (RHNA) for this category
of housing . This development provides 10 lots towards the 132 homes in th is income
category that need to be developed during the 2020 General Plan build out period . This
project would contribute to the town's proportion of regional housing supply requirements
and also be consistent with the development of 1,600 new housing units as anticipated
by the 2020 General Plan .
D. That the WAC cancellation will not result in discontinuous patterns of urban
development.
The WAC cancellation for the existing agriculturally designated ground will not result in
the removal of adjacent lands from agricultural use to a more urbanized envi ronment.
The Project is surrounded by hillside residential properties. Therefore, the Project and
the subdivision of the land to hillside residential homes would not encourage removal of
nearby lands nor encourage "leap frog" development of u rban uses.

E. That the re is no non-contracted vacant land with in three-miles of the subject property -
see attached map) of the subject Property which is both available and su itable for the
use to which it is proposed the contracted land be put or that development of proximate
non -contracted land . The term "suitable" for the proposed use means that the salient
features of the proposed use can be served by land not restricted land may be single
parcel or may be a combination of contiguous or discontinuous.
No proximate non-contract lands that are available and/or suitable for the development
of 10 single-family homes and an open space parcel within Three-miles of the property .

RE: Biological Technical Memo evaluating project impacts on regulated habitats for the
Surrey Farm Estates DEIR (August 2015), Town of Los Gatos, Santa Clara County,
California.
Dear Ms. Ramsbottom :
The following memo evaluates impacts to regulated habitats (i.e ., Waters of the U.S. and State)
on both the proposed project and the new Two Access Alternative relying on new information
provided by the U.S. Army Corps of Engineers (Corps) as to their jurisdiction on the project site.
The primary objective is to incorporate this updated data and analysis into a revised DEIR for
the Surrey Farm Estates Project. We have also recommended some additional small changes to
better reflect CEQA requirements.
The mitigations provided for the bats are somewhat inconsistent with bat biology and timing of
various types of surveys . We recommend to replace those mitigations with the following,
which ensures that the project would not impact roosting bats nor disturb any active maternity
colonies, if present. These mitigations would be consistent with either the proposed project, or
the new Two Access Road Project. See the recommended changes below :
Mitigation Measure 4.3-4, Protection of Roosting Bats
Implementation of these measures would reduce impacts to maternity colonies or roosting bats
to a less than significant level.
a. A habitat assessment (e.g ., visual inspection of trees for sign or evidence of bats) for
roosting bats should be conducted prior to any demolition or tree removal. The explicit
purpose of these surveys is to identify potentially suitable roosting habitat in the trees
and outbuilding onsite . For example, not all trees or structures support potential
roosting habitat, and many of these features can be excluded from further
consideration by a thorough habitat assessment by a qualified biologist . In addition, a
qualified biologist can also employ a lift to visually inspect potential tree cavities to
more definitively determine if roosting bats are present .
b . For any trees and/or the single outbuilding that are found not to be suitable roosting
San Jose: 6840 Via del Oro, Suite 220 • San Jose, CA 95119 • Phone: (408) 224-8300 • Fax: (408) 224-1411

Bakersfield: 8200 Stockdale Highway, M10 -293. Bakersfield, CA 93311
habitat or for any tree or outbuilding definitively determined that roosting bats are
absent, may be removed with no further action .
c. For any trees and/or the single outbuilding that are found to be potentially suitable
for roosting bats, different measures are required depending on the season they are to
be removed.
1. From March 1-April 15 and August 15-0ctober 15 a two-step removal
process should be in place under the direction of a qualified biologist.
2 . From October 16-February 28 the two-step removal process should not occur
so as to avoid take of overwintering bats.
3. From April 15-August 14, the two-step removal should not occur if a
maternity colony is detected or suspected . At this time, nighttime emergence
surveys can be conducted to determine if bats are using these trees or the
outbuilding.
i. If nighttime emergence surveys determine that the tree(s) or
outbuilding do not support roosting bats, these can be removed within 2
days of the survey.
ii. If on the other hand, nighttime emergence surveys determine that the
tree(s) or outbuilding do support a maternity colony, then tree removal
or demolition would have to wait until August 15 or until a qualified
biologist has determined the maternity colony is no longer present.
iii. If nighttime emergence surveys determine that the tree(s) or
outbuilding does support roosting bats but does not support a maternity
colony, a two-step removal process may commence under the direction
of a qualified biologist.
IMPACTS TO WATERS OF THE U .S. AND STATE FOR THE PROPOSED PROJECT
The DEIR (August 2015) notes that Ross Creek, an intermittent "blue line" stream course, abuts
the project site at the southwestern corner. Ross Creek crosses the property via a buried 36"
corrugated metal pipe built sometime prior to 1920, and daylights well off the project site,
some 650' downstream from Hillbrook School campus . The DEIR identifies an ephemeral
drainage swale crossing the site from southwest to northwest. This swale is incised for only
short reaches in the upper portions of the site. Apparently, surface flows from the ephemeral
drainage swale are picked up at a culvert inlet located near the property's northwestern corner
and conveyed via a buried pipe approximately 200 feet to the west, where it empties into the
buried culvert associated with Ross Creek .
LOA, wetland ecologist Pam Peterson, visited the site with Mr. Keith Hess from the Corps on
June 30, 2016 for the explicit purpose of establishing what if any features on site met the
definition of Waters of the U.S . and would then be regulated by them . Mr. Hess from the Corps
determined that the only area falling under their jurisdiction was a 340 ft 2 seasonal wetland in
the northwest corner of the site. His wetland verification visit found that the ephemeral
drainage swale crossing the site failed to meet the Corps technical definition of Waters of the
U.S . Therefore, the only feature regulated by the Corps on the project site is the 340 ft 2
seasonal wetland in the northwest corner of the site.
The Corps does not consider the ephemeral drainage swale as a Waters of the U.S. and
therefore it would not regulate impacts to this feature, nor any other area on site . However,
for the purposes of evaluating impacts in the DEIR, it has been assumed that the Regional
Water Quality Control Board (RWQCB) under Section 401 of the Clean Water Act and the State
Porter Cologne Act, and the California Department of Fish and Wildlife (CDFW) under Fish and
Game Code Section 1602, may regulate impacts to this drainage swale.
While the RWQCB would also regulate actions that result in discharge or fill of the seasonal
wetland in the northwest corner of the site, the California Department of Fish and Wildlife
(CDFW) would not as this feature does not have a defined bed and bank as required by Fish and
Game Code.
The project will avoid impacts to the single small wetland in the northwest corner of the site by
constructing the bioswale and detention basin to the southeast of this wetland and by jacking
and boring under the wetland at a minimum depth of 30 inches in order to install a 27-inch
storm water line that will connect to an existing underground line that occurs northwest of the
wetland, approximately 5 ft . below grade. However, the construction of Streets A and B of the
proposed project would impact portions of the ephemeral drainage channel.
Impacts to the ephemeral drainage swale from the construction of Street A and B are
considered a significant impact to sensitive aquatic habitat for the purpose of this analysis.
Impacts to this drainage swale, while not regulated by the Corps, may be regulated the RWQCB
and CDFW.
The following mitigation is proposed to reduce impacts to the ephemeral drainage swale to a
less than significant impact.
Mitigation. Avoidance, minimization, and/or compensation measures should be implemented
to reduce to the ephemeral drainage swale to a less-than-significant level.
Mitigation 4.3-la (Avoidance). The preferred method of mitigation would be
avo idance of all impacts to the ephemeral drainage swale.
As the proposed project is designed, it is not possible to avoid all regulated habitats
because of the current road design . Thus, full avoidance of the drainage swale is not
feasible .
Mitigation 4.3-lb (Minimization). Because full avoidance is not possible, actions should
be taken to minimize impacts to the ephemeral channel (e.g ., potentially waters ofthe
State and under the jurisdiction of both RWQCB and CDFW). Measures taken during
construction activities should include placing construction fencing around the riparian
habitat and ephemeral channel to be preserved to ensure that construction activities do
not inadvertently impact these areas .
Mitigation 4.3-lc {Compensation). The Proposed Project would impact some small
areas of an ephemeral drainage swale resulting from construction of Streets A and B.
Therefore, the project should replace the lost habitat value resulting from this impact
through the creation, restoration, and/or enhancement of riparian habitat at the impact
location or at one or more appropriate locations near the impacted areas at a minimum
of a 1 :1 replacement-to-loss ratio and no more than 3 :1 for permanent acreage impacts
(up to 3 acres created for each acre permanently impacted) as well as reseeding or
replanting of vegetation in temporarily disturbed areas according to a site-specific
mitigation plan. The final mitigation amounts will be based on actual impacts to be
determined during the design phase. If impacts are lessened, then the amount of
mitigation should be appropriately reduced .
It is expected that all compensation measures can be accommodated onsite within the
existing ephemeral channel. An onsite habitat mitigation and monitoring plan (HMMP)
would need to be developed with the goal of creating, restoring, and/or enhancing
riparian habitats with habitat functions and values greater than or equal to those
existing in the impact zone. As such, compensation measures should include, but would
not be limited to:
• Replacement of all riparian trees (i.e., trees typically associated with riparian
woodland habitats) at a replacement-to-removal ratio that conforms with the
Town's tree replacement standard. To the maximum extent practicable,
removed trees should be replaced with like species or, if such trees are non-
native, with species that are known to occur naturally within riparian habitats in
the region . These trees should be planted along the ephemeral channel for
riparian restoration. Replacement trees should be grown from seeds, acorns, or
other planting stock collected from the site or from nearby creeks within the
same watershed .
• Reseeding or replanting of riparian or vegetation (i.e ., a combination of trees,
shrubs, and herbaceous vegetation) in temporarily impacted areas and
designated habitat restoration areas .
At a minimum, the HMMP should include:
•
•
•
•
•
•
•
•
The location of all enhancement and/or restoration activities;
Evidence of a suitable water budget to support any created habitats;
Planting specifications;
Site maintenance and management requirements;
Monitoring requirements;
Final success criteria;
Adaptive management procedures; and
A long-term funding mechanism for site management into perpetuity .
The monitoring period should be a minimum of five years to ensure that the success
criteria have been achieved .
Regulatory Framework:
Impacts to the ephemeral drainage channel, while not regulated by the Corps, may be
r egulated by the RWQCB and CDFW . The applicant should therefore, seek authorizat ion from
the RWQCB or CDFW for any impacts to the ephemeral drainage channel that cannot be
avoided . If the project is able to implement an avoidance strategy, that would vacate the need
to obtain permits from either agency.
IMPACTS TO WATERS OF THE U.S. AND STATE FOR THE NEW TWO ACCESS ROAD
ALTERNATIVE PROJECT
The new Two Access Road Alternative Project will avoid all impacts to the seasonal wetland and
the ephemeral drainage swale. Therefore, this Alternative vacates the need to obtain permits
from the Corps, RWQCB and CDFW as it employs a total avoidance strategy -the preferred
option by the agencies.
The single small wetland in the northwest corner of the site will be avoided by constructing the
bioswale and detention basin to the southeast of this wetland and by jacking and boring under
the wetland at a m inimum depth of 30 inches in order to install a 27-inch stormwater line that
will connect to an existing underground line that occurs northwest of the wetland,
approximately 5 ft . below grade. Access roads have in this Alternative been designed
specifically to avoid the entire drainage swale, thereby resulting in a total avoidance scenario.
Therefore, this Alternative results in a less than significant impact to sensitive aquatic and
wetland features as it avoids all impacts to them.
Mitigation. As the project avoids impacts to these sensit ive habitats no mitigation is
warranted .
Regulatory Framework:
No regulatory permits are requ i red nor applicable fo r this Alternative as all potential features
are being avoided .
If you have any questions, or need additional i nformation o r clarifications, please feel free to

The intent of this letter is to estimate the fair market value of your land in Los Gatos.
After reviewing the past sales of lots located in Los Gatos and Saratoga since
January 2016 forward, it is my opinion that the value of your land as it is currently
zoned, would be approximately three million eight hundred thousand
($3,800,000.00),

1.0 INTRODUCTION
AEI Consultants (AEI) is pleased to provide this report which describes the activities and results
of samp ling for chlorinated pesticides, chlorinated herbicides, dioxins, furans and metals
performed at the above referenced property (Figures 1 and 2). This investigation was
completed in general accordance with the authorized scope of services outlined in our signed
proposal number 32200-8 dated September 21 , 2012.
2.0 SITE DESCRIPTION
The site consists of 16.37 acres of partially wooded , undeve loped former orchard land east of
Twin Oaks Drive in Los Gatos . The property has been divided into 11 parcels for a proposed
development. A 1939 aerial photograph shows the property as being under orchard cultivation.
The property varies in elevation from a high of 945 feet above mean seal level (amsl) on a knoll
in the southeast corner of the property to 425 at the western edge of the property.
3.0 BACKGROUND AND PURPOSE
AEI was requested to perform shallow soil sampling for chlorinated herbicides, chlorinated
pesticides, dioxins/furans, and CA Title 22 metals (Cam 17) to confirm the presence or absence
of these chemicals which may have been used on the site during operation of the former
o rchard .
4.0 INVESTIGATIVE EFFORTS
Permits & Clearances
No boring permits are required from the Santa Clara County Water District as the soil borings
were shallower than 45 feet bgs. The work area was clearly identified with white marking paint
and Underground Service Alert North (USAN) was notified in compl iance with state law.
Health & Safety
AEI prepared a site specific Health and Safety Plan (HASP). On November 7, 2012, prior to the
start of field activities drilling, a tailgate safety meeting was held at entrance of the work area
to review the HASP . Work ing ha zards and emergency procedures were discussed at this
meeting, including an ex planat ion of the hazards of the known or suspected chemicals of
interest as well as the location and route to the nearest hospita l. All site personnel wore
modified Level D personal prot ection equipment.

Soil Sampling
4.3.1 Sample Locations
The subject property is undeveloped but has been divided into 10 lots to be developed and one
lot designated "open space" lot (see Figure 2). Three (3) soil sampling locations (A, B, and C)
were selected on each lot and two samples were collected from each location. Surface soil
samples were collected from a depth of 0.0 -0 .5 feet below the ground surface (bgs) and were
labeled with the letter suffix added as shown below:
• SS-1-A, SS-1-B, SS-1-C and SS-2-A, SS-2-B, SS-2-C, etc.
Soil samples were also collected from a depth of 1.0 -1.5 feet bgs and labeled in the same
manner as surface samples with the letter suffix added as shown below :
• SS-1-0, SS-1-E, SS-1-F and SS-2-0, SS-2-E, SS-2-F, etc.
4.3.2 Sample collection
A total of 33 surface (0.0 -0.5 feet bgs) and 33 deeper (1.0 -1.5 feet bgs) samples were
collected at the site on November 7, 2012. Where accessible, samples were collected using a
Geoprobe® 5400 series, truck mounted, direct push, four wheel drive, drilling rig operated by
Environmental Control Associates, of Aptos, CA, California C-57 (drilling) License 695970.
Samples were collected using a standard 2.25-inch outside diameter by 4-feet long Geoprobe
Macro-Core® soil sampler. The Macro-Core® sampler is lined with an inert plastic sample liner
to collect the continuous sediment core . At each accessible location, the sampler was driven to
depth of approximately 2.0 feet bgs, to allow recovery of at least 18-inches of soil in the
sampler. The sampler was then retrieved, disassembled, and the sample liner containing the
core removed and transferred to the onsite AEI geologist. Samples from several locations on
steep hillsides that were inaccessible by truck were collected manually using hand tools. A
detailed description of the soil cores was not made, however the soil present on the site
typically consisted of light brown sandy clayey silt to silty clay with common gravel, pebbles and
cobbles of igneous and metamorphic origin. The coarser sediment appears to represents lag
deposit derived from the igneous and metamorphic rocks outcropping in the hills to the south of
the site.
Soil samples were retained from the intervals of 0.0-feet to 0.5-feet bgs and 1.0-feet to 1.5 feet
bgs . The shallow soil samples were placed into laboratory supplied 4-ounce (oz) glass jars.
Samples from the depth of 1.0-feet bgs were cut from the liner. The ends of each liner were
sealed with Teflon® tape and plastic end caps. Each sample was labeled with a unique
identifier, project number, time, date and sampler ID. The samples were then entered on a
cha in of custody record, and placed in a pre -chilled cooler on water ice pending transportation
to the laboratory.
Samples were transported by the sampler under chain of custody protocol to McCampbell
Analytical , Inc. of Pittsburg, California (OHS Certification #1644). The surface soil samples
were composited into 3 point composites by the laboratory and analyzed for Organochlorine
Pestic ides by GC-ECD (8080 Bas ic Target List) by Method SW8081A; for Chlorinated He rbicides
by GC-ECD (Basic Target List) by method SW8151A; for Polychlorinated Dibenzo-p-Diox ins
(Dioxins) and Polychlorinated Dibenzofurans (Furans) by method SW8280A; and for CAM/CCR
Project No . 313883

17 Metals (Title 22 Metals) by method SW6020 . The deeper soil samples were held for possible
analysis following evaluation of the shallow soil samples. Copies of the analytical reports with
chain of custody documentation are included in Appendix A.
Boring Destruction
Following completion of sampling, each soil boring was backfilled filled with compacted native
soil.
5.0 FINDINGS
The San Francisco Bay Regional Water Quality Control Board (SFB-RWQCB) and California
Department of Toxic Substance Control (DTSC) have the responsibility for overseeing soil and
groundwater cleanups which are managed under a variety of different regulatory
programs. The results of this investigation were compared with the RWQCB Environmental
Screening Levels (ESLs) for Shallow Soil Screening Levels ( <3 meters bgs) for Residential Land
Use where groundwater is not a potential drinking water resource and the DTSC California
Human Health Screening Levels (CHHSLs) to evaluate the potential for impact to the
environment and human health. The RWQCB ESLs which are designed primarily for protection
of the groundwater are typically used by Santa Clara County Environmental Health (SCCEH) at
petroleum based sites while the CHHSLs are typically used to evaluate human health concerns
with regard to surface occupancy.
5 .1 Soil Sample Analytical Results
Pesticides and Herbicides
No organochlorine pesticides or chlorinated herbicides were reported at or above laboratory
reporting limits . The analytical results for organochlorine pesticides and chlorinated herbicides
are summarized on Tables 1 and 2, respectively .
Dioxins
The least toxic of the dioxins, Octachlorodibenzodioxin (OCDD), was reported in samples 55-1-
A,-B,-C and 55-3-A,-B,-C through SS-11 A,-B,-C at concentrations ranging from 10.2 nano-
grams per kilogram (ng/kg) (55-3-A,-B,-C) to 43.4 ng/kg (55-8-A,-B,-C). OCDD was reported as
non detectable in sample 55-2 at a reporting limit of 5.0 ng/kg . The most toxic of the dioxins,
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) was reported as non detectable at a reporting limit
of 1.0 ng/kg. All other dioxins were reported as non detectable at their respective reporting
limits.
Furans
No furans were reported at or above laboratory reporting limits. The analytical results for
dioxins and furans are summarized on Tables 3.
Metals
Arsenic was reported in all samples at concentrations ranging from 2.3 mg/kg to 7.0 mg/kg. All
of these values exceed both the CHHSL of 0 .07 mg/kg and RWQCB ESL 0.39 mg/kg . However;
back ground levels of arsenic commonly exceed these established guidelines. The 1996
Kearney Foundation report, Background Concentrations of Trace and Major Elements in
California Soils, reported arsenic concentrations ranging from 0.6 mg/kg to 11 mg/kg. As a
Project No . 313883

Consultants
consequence of high background levels in the area , Santa Clara County Environmental Health
commonly accepts concentrations of arsenic up to 14 mg/kg for residential property. AEI does
not consider the reported concentrations of arsenic as significant.
Mercury was reported in one sample (SS-4-A) at a concentration of 1.4 mg/kg which is above
the ESL of 1.3 mg/kg but be low the CHHSL of 18 mg/kg. Re-extraction and analysis of sample
SS -4-A reported a concentration of 0.11 mg/kg which gives an average mercury concentration
for the lot of 0. 76 mg/kg. All other samples reported mercury at concentrations below the ESL
and CHHSL. AEI believes all mercury concentrations reported are within the range of normal
background for the area and does not consider the reported concentrations of mercury as
sign ificant.
Nickel was reported in one sample (SS-1-A) at a concentration of 330 mg/kg which is above the
ESL of 300 mg/kg but below the CHHSL of 1,600 mg/kg . All other samples reported nickel at
concentrations below the ESL and CHHSL. AEI believes all nickel concentrations reported are
within the range of normal background and does not conside r the reported concentrations of
nickel as significant.
Vanadium was reported at concentrations ranging of 39 mg/kg to 80 mg/kg. All of these
reported concentrations are above the ESL of 16 mg/kg but below the CHHSL of 530 mg/kg. All
of the concentrations reported are with in the background concentrations reported in the
Kearney report. AEI believes all vanadium concentrations reported are within the range of
normal background and does not consider the reported concentrations of vanadium as
significant.
The standard CAM 17 analysis reports total chromium, which includes both chromium III and
chromium VI, while the regulatory guidelines have been establ ished for both species of
chromium . Typically chromium VI represents a small fraction of the total chromium . Follow ing
the common practice, the samples with total chromium concentrations at or above 100 mg/kg,
were analyzed for chromium VI. All these samples reported chromium VI as non-detectable at
the laboratory reporting limit of 4 .0 mg/kg. AEI believes all chromium concentrations reported
are with in the range of normal background and does not consider the reported concentrations
of chromium as significant.
Concentrations of antimony, barium, beryllium, cadmium, cobalt, copper, lead, molybdenum,
selenium, silver, thallium , and zinc were reported below both the RWQCB ESL and the DTSC
CHHSLs .
6.0 SUMMARY AND CONCLUSIONS
No organochlorine pesticides or chlorinated herbicides were reported in the soil samples . All
metals except for arsenic, mercury, and vanadium were reported below both the RWQCBs ESLs
and CHHSLs.
Vanadium and mercury concentrations are within expected background concentrations and
below the CHHSLs . Arsenic was reported at concentrations above the RWQCBs ESLs and
Project No . 313883

CHHSLs but is within normal background concentrations and below the Santa Clara County
Environmental Health's arsenic standard of 14 mg/kg.
No furans were reported at or above the laboratory reporting limits and no dioxins except OCCD
were reported at or above laboratory reporting limits. No ESL or CHHSL has been establ ished
for OCDD . Toxic Equivalency Factors (TEF) for dioxins are listed in Department of Toxic
Substances Control (DTSC) Human Health Risk Assessment (HHRA), Note 2 (attached in
appendi x A). TTCD which has an ESL and CHHSL of 4 .5 ng/kg and 4.6 ng/kg, respectively, is
the most toxic of the dioxins listed and has a TEF of 1.0. OCDD with a TEF of 0 .0003 is the
least toxic d ioxin on the list. The ratio of TEFs and the TCCD ESL can be used to establish an
equiva lent ESL for OCDD . 4 .5 ng/kg divided by 0.0003 gives an equivalent ESL for OCDD of
15,000 ng/kg. For this reason , the reported concentrations of OCDD are not considered
significant.
Based on a comparison of the laboratory analytical results and the CHSLs, the subject site will
meet the established DTSC criteria for residential development.

MS / MSD spike recoveries and / or %RPO may fall o utside of laboratory acceptance criteria due to one or more of the following reasons: a) the sample is inhomogenous AND contains
significant concentra1ions of analyte relative to the amount spiked, orb) the spiked sample's matrix interfere s with the spike recovery.
NIA = not applicable to this method .
NR = analvte concentration in samole exceeds spike amount for soil matrix or exceeds 2x scike amount for water matrix or sample diluted due to hiqh matrix or analvte content.

HUMAN HEAL TH RISK ASSESSMENT (HHRA) NOTE 2
ISSUE DA TE: May 2009 INTERIM
ISSUE: Remedial Goals for Dioxins and Dioxin-like Compounds for Consideration at
California Hazardous Waste Sites
SUMMARY
This note presents a suite of suggested Dioxin-TEO soil remedial goals that have been
developed for consideration at mitigation sites in Californ ia for the protection of human
health . These goals may be revised in the future, as new scientific information
becomes available .

Residentiala ,o 50 • 10-6 risk level
• 95% UCL
Commercial/lndustrialc 200 -1000 • 10-6 risk level -HI of 1
• 95% UCL
Agricultural 0 <40 • Based on Germany Guideline
(6)
• Ceiling value
a) Based on the California Human Health Screening Level (CHHSL) (3). The CHHSL is
adjusted , multiplied by 10, to account for the minimal contribution of soil and dust to
the dioxin human body burden as shown in the University of Michigan Dioxin
Exposure Study (7, 8). In this study of 946 persons , it was found that less than
0.01 % of the variation in serum dioxin concentrations could be attributed to soil and
household dust polychlorinated dibenzo-p-dioxins (PCDDs). Similar observations
were made in a study of women in West Virginia (4). EPA SW-846 screening level
bioanalytical assays (4000 series) may be considered in initial site investigation
activities, if this remedial goal is used.
b) The suggested residential remedial goal should only be considered if no farming
(raising food animals and/or the majority of the food supply of families) is likely to
take place at the site .
c) A range is proposed from a 10-5 risk , based on the commercial/industrial CHHSL (3)
to a concentration based on a Hazard Index of 1 (see below). This risk range should
be adequately protective , given the results of the dioxin exposure studies (7, 8, 4).
d) Use of this remedial goal as a ceiling value should result in 95% UCL concentrations
close to 10 ppt, the guideline for dairy farming in The Netherlands and sensitive uses
in Sweden (6).
Dioxin remed ial goals based on non-cancer effects : A non-cancer remedial goal of 78
ppt is calculated for the residential child based on 1 pg/kg/day (the Minimum Risk Level ,
MRL, based on neurological effects in monkeys) (1 , 10). Therefore, the suggested
residential remedial goal of 50 ppt should be protective of non-cancer adverse health
effects . The non-cancer commercial/industrial remedial goal is 1,000 ppt, based on the
same MRL.
Dioxin remedial goals based on the protection of ecological health : This is variable
depending on the ecological receptors of concern at the site but may drive a risk-based
cleanup.

The TEQ concentrations shown in Table 1 are calculated by converting the measured
congener concentration in a soil or sediment sample by its TEQ, shown in Table 2, and
adding these converted values to get a Dioxin-TEO concentration for the sample .
These TEQs were accepted by the DTSC/HERD October 2006.
