4DMINISTRATlON
Dear Ms Quinney:
Subject:
San Tomas Injection Well, Demonstration Test Well, Project No. 9417-101-Encroachment
Permit Request
The Santa Clara Valley Water District (District) requests an encroachment permit to excavate within the
intersection of Bucknall Road and Virginia A venue to install a tap on our existing Campbell Distributary
and construct a temporary pipeline to convey treated water to the Demonstration Test Well site (see
Sheets 4 and 5 of the enclosed Plans and Specifications). The pipeline originates at the intersection of
Bucknall Road and Virginia A venue, continues eastward beneath West Rincon A venue, and then south
along the levee surface of the San Tomas Aquino Creek to the injection well site.
The construction of this Demonstration Test Well and pipeline is necessary to verify the ability of the
aquifer to receive injecta water from our Rinconada Water Treatment Plant. This project will be
advertised in early April 1996 with construction activity to begin in late May 1996. Overall construction
will take approximately 60 days and consists of approximately 1100 feet of 6-inch diameter pipeline and
the drilling of a 620-foot deep, 14-inch diameter injection well.
The District has taken the following steps to fully address the concerns listed in your letter dated,
January 4, 1996, regarding the potential noise impacts associated with this project's 24 hour-per-day
drilling operation which may last up to 7 days:
· Additional Neighborhood Meeting
An additional informational neighborhood meeting was held at the Campbell Community Center
on Thursday, February 15, 1996. A resident informational mailing for this meeting was delivered
to over 600 tenants and property owners who may possibly experience noise impacts form this
project's drilling operation. For more information on this meeting, please refer to the meeting
invitation that was mailed to you on January 25, 1996.
· Construction Notices
The resident informational mailing for the additional neighborhood meeting explicitly explains that,
prior to the commencement of drilling, notices will be distributed to residents 30, 14, and 3 days
to assist residents in preparing for this short duration inconvenience. These construction notices
will provide the residents a District (24 hour-per-day) point of contact during construction of the
"
~J recycled paper
Ms. Michelle Quinney, P.E.

March 4, 1996
Demonstration Test Well and supply pipeline. The requirement for these construction notices is
included in Section 15 of the Specifications for this project. Additionally, the District will also
erect a large sign on the injection well site which describes the project's purpose and provides
contact phone numbers.
· Public Interaction
Only six (6) people from the 600 plus resident information mailing attended the additional
neighborhood meeting on February 15, 1996. There were a total of five phone calls from residents
responding to mailings. The District discussed potential impacts with these individuals as well as
with the five residents who attended the first neighborhood meeting held on September 21, 1995.
There was minimal public reaction displayed by those calling or attending neighborhood meetings.
In all cases, the necessities for this project's 24 hour-per-day drilling operation were explained as
discussed in our letter to you dated, December 18, 1995.
· Noise Mitigation
The District's noise mitigation efforts were discussed in detail at both meetings and in the resident
informational mailing. Provisions are made in our Plans and Specifications to minimize the noise
impacts on the nearby residents due to drilling. Section 15 of the enclosed Specifications clearly
establishes noise limits of drilling equipment, passing criteria for a noise emissions test during
installation of the conductor casing at the start of drilling operations, and construction of
engineered sound walls around the drilling rig to lessen drilling noise (see Figure No. 1 of the
Plans for sound wall placement). The successful bidder will have to strictly adhere to these
specifications before being allowed to initiate 24 hour-per-day drilling activities.
· Categorical Exemption
Our letter dated December 18, 1995 describes how the District has classified this project as
Categorically Exempt under Section 15304, Applicable Exemption Class 4, Minor Public
Alterations of Land. This classification is based on the minimal public reaction and the temporary
nature of the project. A draft copy of the Categorical Exemption was faxed to you on January 10,
1996. The final Categorical Exemption will be filed when our Board approves the construction
the Demonstration Test Well next month. This Categorical Exemption would apply only to the
construction of the Demonstration Test Well and the associated temporary pipeline.
· Project Schedule and Scope
Once the project is awarded, we will invite you and representatives to a preconstruction meeting
with the successful bidder. A more detailed project schedule will be available at that time. To
date, there are no significant changes to the project's overall schedule as described above nor are
there any significant changes in the project scope. Should there be any major changes in either the
project schedule or scope, we will notify you.
We hope that our actions to date have adequately addressed your concerns regarding the construction of
this Demonstration Test Well and that our request for a permit is favorably considered. Four copies of
our trench alignment and pavement restoration drawings are enclosed for your review as well as portions
of Section 19 of the Specification covering trench backfill and pavement restoration materials. These
Ms. Michelle Quinney, P.E.
3
March 4, 1996
trench and pavement drawings and Specifications conform to the City of Campbell Standard Specifications
and Details, dated 1994.
We ask that an encroachment permit be issued by March 13, 1995, so that construction of the test well,
associated facilities, and temporary pipeline can proceed. Copies of our letter dated December 18, 1995,
the neighborhood meeting invitation dated January 25, 1996, resident informational mailing, and the
categorical Exemption (draft) are enclosed for your convenience and reference. If you have any
questions, please call me at (408) 265-2607, extension 2028.

12.02 Schedule of Work
Except as provided for in the Specifications, the Contractor shall arrange the sequence of operations
in prosecuting the major division of work. Once work has begun, it shall proceed in a manner in
accordance with the accepted schedule.
Since the connection to the Campbell Distributary will require a shutdown of the Distributary, it
will be necessary for the District to suspend delivery of treated water to its retailers during the
shutdown. It is therefore necessary for the Contractor to schedule this shutdown period well in
advance and to confirm the exact schedule with the Engineer, in writing, at 30, 14.. and 3 days
prior to the proposed shutdown. At the time of the 30-day confirmation, the District reserves the
right to reschedule the shutdown period to a later date for reasons of convenience or necessity to
itself or its treated water retail customer. These rescheduling delays will not exceed 14 days. No
additional compensation will be made to the Contractor as a result of rescheduling of the shutdown
period by the District. The period of time for the shutdown shall not extend beyond 36 consecutive
hours.
Immediately prior to the shutdown period, the District will take the existing Campbell Distributary
out of operation and drain the pipe by gravity (blowoff). The Contractor shall provide for any
pumping necessary to further drain the pipe to provide for the connection and valve installations.
The connection and valve installation on the existing Campbell Distributary shall include installation
of a steel tee and butterfly valve, making the physical connections, and repairing the linings and
coatings as shown on the Drawings, and as specified herein. It shall also include the disposal of
any water removed from the pipe by the Contractor in accordance with all applicable federal, state,
or local requirements. If the Contractor decides to dispose of this water into storm drains or into
the creek, he/she shall reduce the chlorine concentration in the water to less than .05 parts per
million (ppm) as required by the Regional Water Quality Control Board (RWQCB). The
Contractor shall notify Mr. Steve Moore of the RWQCB at (510) 286-1262 about the disposal of
such water at least 24 hours, but not more than 72 hours, before the scheduled disposal. Within
the allowable shutdown period, the Contractor shall complete the installation of the steel nozzle and
butterfly valve and required auxiliary equipment and appurtenances such that the valve is watertight
and manually operable.
Upon satisfactory completion of the installation of the steel nozzle and butterfly valve, the
Contractor shall disinfect the localized areas affected by the installations in accordance with
A WW A Standard C651 and return the use of the existing Campbell Distributary to the Engineer.
Upon completion, the District will resume operation of the existing Campbell Distributary.
No other shutdowns of the existing Campbell Distributary will be made during this Contract. The
Contractor is required to complete all items of work which would require a shutdown during this
3-day shutdown period.
12.02.01 Detail Schedule of Work
Within 35 days of the date of the award of the Contract, a Detail Schedule of Work, in writing,
6fl tran~fJ!ireRt sheets, showing all major items of work shall be submitted to the Engineer. The
Detailed Schedule of Work shall identify specific tasks and time duration to perform these tasks.
PC0700
2
12.02.02. Schedule Updates
As the work progresses, the Contractor shall submit to the Engineer on a monthly basis a Progress
Schedule of Work showing the actual status of the work in the respective categories. This schedule
shall be maintained in the Contractor's field office where it will be available to the Engineer at all
times.
12.02.03. Adjustments to Schedule
If the Contractor considers that an ordered change or delay will impact the Contract progress, a
schedule analysis and an updated schedule supporting the Contractor's request for adjustment of
time shall be submitted to the Engineer within 45 days of the occurrence of the ordered change or
delay.
All changes shall be shown as separate activities or groups of activities and entered into the relevant
part of the approved network schedule current at the time of change. In case of a deductive change
reducing the quantity of work to be done under affected activities, the estimated duration of these
activities shall be adjusted to reflect the reduced quantities of work.
The Contractor shall also submit a narrative report describing the adjustments, reasons for the
adjustments, and the impact of the changes.
The Engineer will use these analyses of the effect of the change(s) or delay(s) on the critical path
and the approved schedule current at the time of the change(s) or delay(s) to determine the
applicable adjustment of time to any target date or completion date due to the change(s) or delay(s).
Only changes or delays that affect or create controlling items of work as defined by the schedule
will result in time adjustments. Extensions of time for the Contract will only be considered if, after
a delay is properly incorporated into the schedule logic, an extension of the project end date beyond
the Contract end date results.
12.03. Liquidated Damages
In accordance with Article 7.06, the District shall deduct, as liquidated damages, from monies due
the Contractor the following amounts:
$150 per day for failure to submit the Detailed Schedule of Work, Schedule of Work,
Schedule Updates, Schedule Adjustments, and Schedule of Submittals within the time limits
allowed.
$157 per d~ for failure to complete all work necessary for the Engineer to initiate the
Injection Test 60 days after the issuance of the Notice to Begin Work.
$730 per hour for each hour exceeding the time specified for shutdown on the existing
eimpbell Distributary.
$530 per day for failure to complete all work included in the Contract within the time limit
~
PC0700

Liquidated damages will be assessed independent of each other. The total damages assessed shall
be the cumulative of the assessed values specified above.
12.04. Hours of Work
Except where specifically stated, normal working hours for the project shall begin no earlier than
7:30 a.m., and end no later than 7:00 p.m., Monday through Friday. However, drilling operation
shall be continuous. Once it has commenced, it shall continue 24 hours per day, 7 days per week,

Dear Ms Quinney:

San Tomas Injection Well, Demonstration Test Well,-Project No. 9417-101
Thank you for the Encroachment Permit No. 94-197, under which the District recently potholed the
existing Campbell Distributary in the northwest corner of the intersection of Bucknall Road and Virginia
Avenue. It is important that we keep the project on schedule, and your assistance in helping us complete
some of the crucial activities is greatly appreciated.
In your November 14, 1995 letter, you expressed concerns regarding the proposed 24-hour per day
drilling operation for our Demonstration Test Well and the noise associated with such drilling activity.
The District shares your concerns and is evaluating ways to minimize the noise impacts. We plan to make
provisions in our contract documents that would limit allowable noise levels of drilling equipment. We
would also require the contractor to construct an engineered sound wall around the drilling rig to further
reduce drilling noise (see attached figure). The contractor would first be required to pass a noise
rehearsal test limiting allowable emissions from the drill rig to 65 dBA at 100 feet. This emission level
would produce noise contours similar to the contours shown on the attached figure. The District will also
investigate other possible options.
We believe that keeping the community informed is an integral factor in the successful completion of this
project. We invited several nearby residents for a neighborhood meeting held on September 21, 1995.
At the meeting we described the project and advised those in attendance about the noise impacts due to
well drilling. We also established personal contact with the Kingdom Hall of Jehovah's Witnesses,
Greenhills Manor Convalescence Home, and The Church of God of Prophecy on Virginia Avenue, who
are all located immediately west of the project site, and spoke with several of the residents just south of
the project site. These contacts were in addition to resident notification for the neighborhood meeting.
To our knowledge, no major concerns have been expressed by anyone.
Based on the minimal public reaction and the temporary nature of the project, the District has classified
this project as Categorically Exempt under Section 15304, Applicable Exemption Class 4, Minor Public
Alterations of Land. This Categorical Exemption would apply only to the construction of the
Demonstration Test Well and the associated temporary pipeline. This demonstration test of the
groundwater aquifer beneath the site must be conducted before a full-scale facility can be considered.
Should the results of the Demonstration Test Well merit the design and construction of a full-scale
injection facility and permanent supply pipeline, a Negative Declaration may be required.

Your letter inquires into the possibility of drilling options that do not require 24-hour drilling operations.
We have attached a letter from our consultant, Fugro West, Incorporated, who specializes in these types
of designs and construction activities. Fugro West's letter explains the need for 24-hour per day drilling
of this Demonstration Test Well. Our Engineering geologist is also in agreement with the need to drill
24-hours per day, citing the same mud invasion and hole stability problems we listed in our November 8,
1995, letter. We hope the information in Fugro West's letter serves to answer your questions.
Fugro West's letter also includes an anticipated noise level model. We are using this model to define the
boundaries for a new informational mailing about this project. This additional mailing is being conducted
so that the District may satisfy the City of Campbell's request that, those residents who may experience
a noise level in excess of the normal ambient noise level, be informed of the project's impacts and provide
them an opportunity to discuss the project at a second neighborhood meeting. The limits of this mailing
are based on the 50 decibel (dBA) contour line shown on the attached figure. The 50 dBA noise level
contour also conforms to Campbell's Municipal Code 18.02.060 concerning construction noise limits.
This mailing will be followed by another neighborhood meeting. Our communication process is consistent
with the District's desire to construct the Demonstration Test Well with as little detrimental impact on the
nearby residents as possible. This additional mailing and neighborhood meeting should assist nearby
residents to better understand the need for this project and prepare for the short-term inconvenience
associated with the 24-hour drilling activities. You are invited to attend this neighborhood meeting and
will be sent the same information as the residents.
Municipalities regularly drill water wells on a 24-hour schedule in situations identical to or worse than
the situation that exists at this project I s location. Wells can be drilled with a minimum of complaints from
those nearby residents experiencing the noise impacts from the drilling. An informational program such
as the one we have already performed, and as you have suggested, which clearly defines when the noise
will begin, how loud it will be, and how long it will last, lays the foundation for residents to prepare for
the short duration inconvenience.
The District would not attempt this project unless it served the interests of Campbell residents as well as
the residents of the entire Santa Clara County. This project will establish a framework for injection wells
at other locations in the Santa Clara County. Additionally, we wish to emphasize that this project is
required by the State Water Resources Control Board to mitigate for the loss of 660 acre-feet of
groundwater recharge in the west San Jose area. This lost recharge was due to the construction of
Highway 85. This project will satisfy the lost recharge and supplement the District's groundwater
recharge program. The District also intends to utilize this project to develop the practical application of
current injection well technology as a possible means to augment water storage capacities in Santa Clara
County.
This project has the support of the Environmental Protection Agency (EPA). The EPA perceives this
project as beneficial to Santa Clara County's groundwater resources and poses no threat to drinking water
quality. The California Regional Water Quality Control Board (RWQCB), San Francisco Bay Region has
adopted the singular Resolution No. 95-211 Waiving Waste Discharge Requirements so that this project
may come to fruition. The California State, Department of Health Services, waived permit requirements,
because the injected water is potable and complies with the State's drinking water standards.
Your letter states that you intend to inform your City Council of this project. Should you wish, the
District would be happy to assist you in your presentation of this project to your City Council. We
welcome the opportunity to convey the importance of this project and that the success of this
Demonstration Test Well represents a tremendous tool in securing the water supply needs and preserving

the natural resources of Santa Clara County. Please let me know when, and if, a presentation is scheduled
as an agenda item for your City Council.
We hope that the information in this letter and the attached letter form Fugro West Incorporated has
adequately addressed your questions and concerns. If you have further questions or desire additional
information on this project, please call me at (408) 265-2607, extension 2359 or Mr. Stein at

San Tomas Injection Well; Drilling Operations and Noise Issues
Dear Mr. Mody:
At your request, we are providing this letter with additional clarification of the nature of
the proposed drilling operations to be conducted at the San Tomas Injection Well location. It is
our understanding that the City of Cambell (City) has raised questions regarding the necessity of
performing drilling operations on a 24-hour basis and the expected noise levels generated from
this drilling. This letter attempts to address the City's questions and concerns.
As way of background, we have provided a brief discussion on rotary drilling and an
overview of the work to be performed.
Rotary Drilling Method. The proposed well is to be constructed by the rotary drilling
method. This methodology utilizes a drilling bit that is rotated on the end of successively-added
lengths of pipe (drill stem) as the drilling advances. Through the drill stem and out jets in the bit, a
mixture of clay (bentonite) and water is circulated to cool the drill bit, advance the hole
hydraulically, and to remove cuttings. The cuttings are removed at the surface and the drilling
fluid is recirculated. The drilling fluid also serves to seal the borehole wall and promote hole
stability by providing hydrostatic pressure against formation waters.
Overview of Work. As you are aware, the proposed drilling program would consist of
the drilling of a 6- to 12-inch diameter pilot boring to a depth of 620 feet. After reaching final
depth, the borehole would be geophysically logged. After logging, the contractor would begin
reaming operations consisting of the progressive reaming of the pilot hole Upon completion of
reaming, the contractor would immediately begin the installation of the casing. As you are likely
aware, the casing in a modern water well is installed in a single continuous operation as each
casing length is welded to the preceeding length. After installation of all of the casing, gravel
packing operations are initiated to fill the annular space around the perforated portion of the
casing string. Following gravel packing operations, the remaining annular space is sealed with
cement.

Basis for 24-hour Drilling Requirement. The specifications require that the well be
constructed on a 24-hour basis for many reasons. Most important are issues of hole stability and
drilling fluid invasion. The most significant factor in hole stabiiIty is the quality of the drilling fluig/
and the length of time that the hole is unsupported. Instability of the borehole can result in hole
collapse, resulting in repeated redrilling, additional development time, and the possibility of hole
abandonment and the redrilling of a new borehole. Hole instabilities derive from either the
swelling of hydrophilic clays or the raveling of sandy materials. Both of these conditions
progressively worsen with increasing duration of time in the borehole; however, both of these
processes can be slowed to a limited extent with proper drilling fluid control. Swelling can be
slowed by controlling drilling fluid characteristics and maintaining circulation. Raveling can be
slowed by developing an adequate wall cake in the unsaturated zones and maintaining sufficient
hydrostatic pressure in the saturated zones. Ultimately, these processes are best controlled by
minimizing the time period in which the borehole is unsupported.
Related to hole stability issues is drilling fluid invasion. The invasion of drilling fluid into
the formation will reduce permeability, thereby reducing well performance and increasing
electrical energy consumption for pumping or injection; ultimately reducing the capacity of the
well. Mud invasion can be minimized by good fluid control and by minimizing the time during
which drilling fluid is in contact with the producing portions of the aquifer. This can be achieved
by minimizing the time required for the final ream, casing installation, and gravel packing.
The recommendation for 24-hour drilling operations also derives from the nature of the
drilling process. Accepted drilling practices require that drilling fluid circulation be maintained
while the drill string (bit and drill stem) is in the borehole. This is to assure that materials above
the bit do not cave on top of the bit preventing its removal. Because of this practice, any time
drilling is terminated and circulation is stopped, the drill string is removed from the borehole. The
requirement to remove the drill string when drilling is stopped means that drilling deep borings on
other than a 24-hour basis is extremely inefficient. Drilling on an 8-hour basis requires installation
of the drill string each morning and removal at the end of the day. Assuming standard 30-foot
drill pipe and an average skill drilling crew, the time to install or remove drill pipe (trip) to a depth
of 600 feet is approximately 2.5 hours. The daily installation and removal of drill pipe will require
over half of the 8-hour work period. This inefficiency increases drilling time substantially,
increasing the time required to drill the pilot hole from approximately one 24-hour day to
approximately five to six 8-hour days. In addition to the increased job duration time, the
increased time in the borehole increases hole stability problems. The reduction in drilling progress
resulting in the switch from 24-hour to 8-hour is further reduced during the reaming operation
because penetration rates are much slower, reducing daily footage between trips.
Well construction (installation of casing, gravel pack, and cement) also necessitates a
continuous 24-hour schedule. As discussed above, borehole stability is a function of fluicr
properties, circulation, and time. Once casing installation has started, the contractor does not
have the ability to circulate fluid and maintain borehole conditions. The contractor also has no
way to remove obstructions that might block the casing. During casing installation, the contractor

is essentially racing against the time required for eventual hole collapse. If the hole would
collapse while installing casing, removal of the casing would likely require the use of a crane and
the cutting of each weld. After removal of the casing, the contractor would have to re-ream the /
hole and attempt to reinstall the6asing. After successful installation of casing, the celerity of
installation of the gravel pack and cement seal is also essential to avoid problems associated with
borehole collapse.
Response to City of Campbell Suggestions
The City of Campbell has suggested that, in order to reduce nighttime noise, the drilling
schedule be modified to perform the drilling of the pilot hole and the upper 300 feet of the final
borehole on an 8-hour a day basis. We have no technical concerns regarding the drilling of the
pilot hole on this schedule. However, we would suggest that, if the pilot hole is to be drilled on
this schedule, the geophysical logging operations be allowed to occur upon reaching final dept~
regardless of time of day. F or the reasons discussed above, the drilling of the pilot hole on this
schedule will take substantially longer and will therefore increase both the drilling and
construction management costs for this portion of the drilling process.
As you are aware, the final borehole will be constructed through a series of progressively
larger diameter reams of the pilot hole. While drilling all but the final ream of the lower 300 feet
of the borehole on an 8-hour basis may serve to reduce noise while minimizing mud invasion in
this production zone, the repeated daily trips in and out of the borehole would likely extend the
drilling operations to approximately 3 to 5 weeks. The duration of time in the borehole and the
number of trips would likely cause borehole stability problems that may cause further extension of
the schedule. Again, the duration of the drilling process will increase both drilling and
construction management costs substantially. These increased costs will be particularly high for
drilling, as drilling contractors are accustomed to amortizing equipment costs on a 24-hour day.
The use of equipment on a 33 percent basis will be accounted for in the contractor's bid footage
rate.
While it is possible that the pilot hole drilling schedule could be modified, we cannot
support the modification of the well construction schedule. Construction of the well on a
schedule other than 24-hour a day would put the completion of the well at risk. We also. do not
believe that a responsible contractor would agree (and therefore bid) to specifications that could
require termination of casing, gravel packing, and cementing operations in the middle of
installation.
Noise Issues
The City has expressed concern over potential noise levels associated with drilling
activities conducted on a 24-hour basis. The following discussion describes potential noise levels
associated with 24-hour drilling operations, and discusses measures that will be incorporated into
the proposed project to reduce potential impacts.

The project site is located directly adjacent to the San Tomas Expressway, which bounds
the eastern side of the project site. Land uses in the vicinity of the project site consist of
residential and public facility uses, with residential units located directly adjacent to the project
site's southern boundary. Ambient exterior nighttime noise levels within urban settings are
typically 45 dBA, although ambient nighttime noise levels in the vicinity of the project site are
expected to be slightly higher due to noise associated with the San Tomas Expressway.
During well construction, short-term ambient noise levels will be increased in the vicinity
of the project site. Drilling rigs of the size to be utilized for this well typically operate at
approximately 85 dBA, measured at a distance of 50 feet. Because of the structure of the human
auditory system, noise level changes of less than 3 decibels are generally not perceptible.
Therefore, an exterior nighttime noise of 48 dBA would maintain typical ambient noise levels
within the project vicinity. Generally, an increase of 10 decibels above ambient (55 dBA) would
be necessary to perceive a "doubling" of noise. Based upon the two parameters discussed above,
and given the typical operational noise levels associated with drilling rigs, a "tolerable" noise level
during nighttime operations can be established within the 50 to 55 dBA range. It should be noted
that individual reaction to noise levels is subjective, and may vary on a case by case basis.
In order to reduce noise exposure to sensitive receptors to the extent feasible, several
noise reduction measures will be utilized during drilling operations. Foremost among these is the
construction of a temporary sound attenuation barrier around the actual drilling rig. The
proposed location of this barrier is shown on the attached figure. The engineered barrier will
utilize sound absorptive materials with a minimum ASTM standard Sound Transmission Class
(STC) rating of 25. Based upon a barrier height of 20 feet, a noise level reduction of 25 to 33
dBA is projected.
In addition, noise levels generated by point sources naturally attenuate at a rate of 6 dBA
per doubling of distance. Projected short-term noise levels associated with project
implementation utilizing sound wall mitigation were modeled, and are shown on the attached
figure. Due to the site's direct proximity to residential uses, residential units south of the project
site will be exposed to short-term noise levels of 60 to 65 dBA, or approximately 10 dBA above
the tolerable noise levels previously discussed. However, as can be seen from the modeled noise
contours, noise exposure above 60 dBA will be limited to the three residential units immediately
south of the project site. Exposure above 55 dBA will be limited to the residential and public
facility uses within an approximately 275-foot radius.
In addition to the utilization of sound buffering techniques, equipment orientation would
be utilized to the extent feasible to provide maximum screening and directional control of noise
sources. Quiet work practices will also be implemented onsite to avoid startling noises, such as
pipe clanking or dropping. Implementation of these measures will be ensured through their
inclusion in the contractor bid. IAdditionally, a District site manager will be assigned to the
project on a 24-hour basis. Implementation of these measures will reduce noise levels associated
with the proposed project to the extent feasible, and in conformance with industry standards.

We understand that construction of a water well on a 24-hour-a-day basis can be
disruptive and a burden on a neighborhood. Having been involved in the construction of many
municipal water wells, we can assure you that the issues of noise are always paramount to a
community. The noise ci,ncems were anticipated and,is such, we incorporated noise suppression
requirements into the drilling specifications. We believe that the noise suppression provisions will
provide adequate protection. We believe that the drilling and construction of the well on a 24-
hour-a-day basis is still the best approach for all parties. The 24-hour-a-day approach, while
creating some noise at night for a short number of days, will complete the project quickly, reduce
cost to the rate payers, and result in a better quality product. Drilling the well on a less than 24-
hour-a-day basis will prolong the project duration, increase project costs substantially, increase
the risk of well collapse and will compromise well performance.
Please call if you have any questions.

AN AFFIRMATIVE ACTION EMPLOYER
January 25, 1996
Dear Resident:
You are invited to attend an informational neighborhood meeting to discuss the construction of the
Demonstration Test Well for the San Tomas Injection Well project. The meeting will begin at
7 p.m. on Thursday, February 15, 1996, in the Roosevelt Redwood Room No. Q-80 of the Campbell
Community Center, 1 West Campbell Avenue, Campbell, California. A site map and directions
to the Community Center are attached.
The proposed Demonstration Test Well is located on a parcel of land adjacent to the San Tomas
Expressway, about 700 feet south of West Rincon Avenue. One of the Santa Clara Valley Water
District's (District) main concerns with this project's construction is the potential noise impacts it may
have on nearby residents during a 24 hour-per-day drilling operation which may last up to 7 days. This
continuous work schedule is a unique necessity associated with installing water wells.
The attached map shows noise level contour rings for 65 Decibels (dBA) which is approximately
equivalent to normal speech at 3 feet. Also shown is a 50 (dBA) noise level contour which is
approximately equivalent to a dishwasher operating in the next room. This noise contour ring model
represents the expected maximum noise emission levels produced by the drilling of the Demonstration
Test Well. By keeping doors and windows shut during construction, the expected noise levels could be
even lower. The District would limit allowable noise levels of drilling equipment by requiring the
contractor to install suitable mufflers and to construct a sound wall around the drilling rig. These
measures will help reduce noise emission levels to those shown on the map. Notices will be mailed to
residents 30, 14, and 3 days before the drilling operation begins, to assist residents in preparing for this
short-duration inconvenience.
This neighborhood meeting will provide an opportunity to become informed of not only the project's
potential noise impacts and the steps that the District is taking to minimize these noise impacts, but also
of the San Tomas Injection Well project as a whole.
At this neighborhood meeting we will:
1. Discuss the District's planning process and how this site was selected.
2. Outline the purpose and current status of the project.
3. Describe the Demonstration Test Well and Temporary Supply Pipeline that will be installed.
4. Discuss environmental issues and associated construction nuisance of this Demonstration Test Well.
5. Receive your comments and incorporate them into this project's environmental documents.

Good Day Randy and Michelle.
I'm faxing a copy of the filed Categorical Exemption. Randy requested a copy at last Thursday's preconstruction
meeting. This is the same CE that I faxed to Michelle in early January. In regards to this project's schedule,
I think we should get one form the contractor within the month.
You will receive plenty of advanced notice before either the pipeline intertie or 24 hour drilling activities begin.
A District 24 hour per day phone number will be furnished before any construction activities begin.
Know that I will make every effort to fully address and resolve your's and the residents' of Campbell concerns
throughout the duration of this project. Please feel free to use me as a District point of contact for any other
concerns in which you think I may be of assistance with.

MEMORANDUM
CITY OF CAMPBELL PUBUC WORKS DEPARTMENT
TO:
Mark Ochenduszko
City Manager
DATE: March 29, 1996
FROM: Michelle Quinney ~
City Engineer
SUBJECT: SANTA CLARA VALLEY WATER DISTRICT - PROPOSED SAN TOMAS
INJECTION WELL PROJECT
Attached is a brief overview of the events that have taken place to date regarding the
SCVWD's proposed San Tomas Injection Well Project. According to the SCVWD Project
Manager, Walt Stein, the current project scheduled is to go to the SCVWD Board for
approval to solicit bids in April, advertising of the project would take place in May, and they
are hoping to begin construction in July. If all goes well with this first project and they are
able to "establish" the well and successfully inject groundwater, they will construct another
well sometime in the Fall 1996.
.SCVWD is proposing to construct a demonstration test well (620 feet deep) on property
located at the corner of Virginia Avenues and Bucknall/Rincon Avenues. The purpose is to
replace 660 acre feet of groundwater recharge area lost with the Route 85 construction in
west San Jose. Treated water would be piped into the well and injected into the underground
aquifer in an attempt to recharge groundwater supplies. This is a pilot project, and if
successful, another well would be constructed in the same location to make the groundwater
recharge/injection well project a permanent facility.
. One phase of the construction of this well requires a continuous 24 hour drilling operation.
SCVWD estimates this phase will take a maximum of 7 days. Other communities have
completed this process in approximately 3 days and SCVWD hopes to be able to do the
same.
.The drill rig is anticipated to produce between 85-95 dBA. SCVWD is requiring the
construction of a mitigating sound wall that would reduce the noise levels by 20 dBA.
. Ambient noise levels for quiet urban and suburban nighttime are shown at 35-40 dBA on
the attached Figure 1 which was provided to me by SCVWD. The consultant working for
SCVWD estimates ambient nighttime noise levels in this vicinity to be approximately 45 dBA
or higher due to noise from the adjacent San Tomas Expressway.
. According to the SCVWD consultant for the project, increases of .10 dBA over the normal
ambient noise levels can be perceived as a doubting of noise. The consultant therefore
........- ...
March 29, 1996

Page
believes that "tolerable" nighttime noise levels for this neighborhood would be between 50-55
dBA.
-SCVWD has prepared the attached Figure 4 showing the anticipated projected noise levels
in the surrounding community resulting from the drill rig following the 20 dBA reduction
from the sound wall.
-We have met with and communicated to SCVWD that we have significant concerns
regarding the nighttime noise emissions from construction of this project, questioned their
environmental review process for this project, and requested that they look for other
locations for the project. There are many reasons why this location was selected by SCVWD
and they intend to pursue the project at this location.
-We have requested that if they continue with this project that they complete an extensive
public information program and be available 24 hours during the nighttime drilling operation
to respond to citizens. SCVWD has agreed to this.
-SCVWD has noticed the surrounding community of the project and has held two
community meetings (September 21, 1995 and February 15, 1996) which were not well
attended by the community.
\1/ . -As requested by Campbell staff, SCVWD has agreed to notice all residents within the 45
~ dBA contour line (on Figure 4) 30, 14 and 3 days prior to the nighttime drilling operations,
and has agreed to include a 24 hour contact number for the SCVWD project manager on the
notices.
I have prepared the attached draft letter for you to communicate our concerns to the
SCVWD. Please let me know if you need any additional information.

Dear Ms. Quinney:
Subject:
San Tomas Injection Well, Demonstration Test Well-Project No. 9417-101
Attached for your reference are the final plans and specifications for the construction of the San Tomas
Injection Well, Demonstration Test Well. This project has heen advertised and construction should begin
in October 1996.
Mr. Randy Westfall will be invited to the pre-construction meeting with the contractor. In review, the
City of Campbell's (City) encroachment permit requires receipt of the contractor's insurance certificates
before construction begins. The encroachment permit also stipulates that final project closeout and release
of the contractor's surety bonds are contingent upon the City's satisfaction with the finished work within
your right of way. We will ensure that the Santa Clara Valley Water District and its contractor comply
with the conditions of the permit.
In regards to the specifications, please observe the incorporation of the City's Standard Specifications for
2 sack sand-cement slurry backfill and pavement restoration in Sections 19.08 and 19.09, Sheet 4, and
Details 1 and 2 of Sheet 8. Additionally, although not specifically requested, we have added traffic
control (Section 26). I also invite you to review the noise mitigation measures specified in Section 15.02,
and note the incorporation of your concerns of this project's potential noise impacts.
We look forward to working with the City to complete the construction of this portion of the San Tomas
Injection Well program. If you have any questions, please call me at (408) 265-2607, extension 2028.

Dear Stan:
I have recently been briefed by my staff on the Santa Clara Valley Water District's San Tomas
Injection Well Project proposed for construction in the City of Campbell near the intersection
of Virginia Avenue and Rincon/Bucknall Avenues. Although I understand this project was
required by the State Water Resources Control Board as a Route 85 construction mitigation
measure, I am concerned about the impacts that the construction of this project will have on the
Campbell residents surrounding the proposed. well site.
I would urge the SCVWD to make every effort to reduce the noise impacts on the surrounding
neighborhood and to ensure that the residents that will be affected. by such a project have a clear
understanding of the necessity of the project and the impacts upon their neighborhood during
construction.
A comprehensive and effective public information campaign should continue to be a key
component of the project so that residents remain informed and have a meaningful opportunity
to provide feedback to the District.

Dear Stan:
I have recently been briefed by my staff on the Santa Clara Valley Water District's San Tomas
Injection Well Project proposed for construction in the City of Campbell near the intersection
of Virginia Avenue and RinconlBuckna1l Avenues. Although I understand this project was
required by the State Water Resources Control Board as a Route 85 construction mitigation
measure for the loss of 660 acre-feet of groundwater recharge in the west San Jose area, I am
concerned about the impacts that the construction of this project will have on the Campbell
residents surrounding the proposed well site.
As I understand this project, the establishment of the first well will involve a 7 day 24 hour
continuous drilling process that will consist of a large drill rig emitting decibles in the range of
85-95 dBA. This will be in stark contrast to the nightime ambient noise levels of approximately
35-45 dBA. If the fIrst well is successful, the drilling of the second well will repeat this
process. I also understand that your project managers are investigating various means to reduce
the projected noise levels, but that a reduction to the ambient levels is not possible. If there is
no other location that would allow for the development of these groundwater recharge wells, and
the Santa Clara Valley Water District is to proceed with this project at the Campbell location,
it is imperative that all options to reduce the impacts to the surrounding community be
investigated and implemented. This should include investigation into the most technologically
advanced methods and equipment available for this type of construction in this environment.
Any options that could reduce the impact of nighttime drilling hours should be implemented.
The project should also require the use of the most efficient and quiet equipment available and
references on the selected contractor should be diligently reviewed to ensure that the selected
contractor has the required equipment and the ability to complete a project of this nature quickly,
efficiently, and responsively with the least possible impact on the neighborhood. Postponement
of the project to the winter months should also be considered to allow the surrounding residents
to comfortably keep their doors and windows closed and help to reduce the noise intrusion.

Your Project Manager has indicated that the two public information meetings held by the District
on September 21, 1995 and February 15, 1996 were not well attended by the surrounding
community. This lack of involvement by adjacent residents is of great concern because of the
major intrusion of the project within a quiet residential neighiborhood.
Every effort should be made to ensure that the residents that will be affected by such a project
have a clear understanding of the necessity of the project and the impacts upon their
neighborhood during construction.
