It was moved by Vice-Chair Peloza, seconded by Chairman Wagner, that the Committee
approve the Public Works Committee minutes for date, January 18, 2011.
Motion carried 2-0.
B. GRANT PERMISSION TO ENTER INTO CONSULTANT AGREEMENT NO. AG-C-401 WITH
TECHNICAL SYSTEMS INC. FOR TECHNOLOGY IMPROVEMENTS ON PROJECT NO.
C524A, SCADA SYSTEM IMPROVEMENTS PROJECT
Project Engineer Lee stated that this project is a technology improvement project, where the
design, software, hardware and construction costs are combined, in response to a question
asked by Chairman Wagner. Chairman Wagner pointed out that there is no competitive bid for
the construction as there is with other projects. Lee explained that the contract value is based
on negotiation between the City and the consultant consistent with other consultant contracts.
Assistant Director/City Engineer Selle stated that the project scope involves technology
enhancement where the consultant assures that the SCADA equipment is integrated with the
software. How the system is set up to interface is very much dependent on the consultant's
professional judgment and services. The project does not lend itself to a typical bidding
process but is more appropriate for a design/build process.
Chairman Wagner verified that Council has approved a budget of $4,099,621.43 for the project.
Project Engineer Lee verified that to be correct and said that is the "not-to-exceed" amount for
the agreement. Vice-Chair Peloza asked if there is a full test of the system included in the
agreement amount. Project Engineer Lee described how the overall system and each site will
be tested. The contract is organized such that testing of specific phases of the installation will
be approved by the City prior to beginning the next phase of the system installation.
Project Engineer Lee answered questions asked by Vice-Chair Peloza, stating that the
consultant will provide maintenance to the system until the complete new system is accepted by
Page 1
Public Works Committee Minutes February 7, 2011
DRAFT MINUTES
the City. The consultant will provide training to staff as part of the contract. After completion of
the new system, the City would need to determine the extent or need for a maintenance
agreement with a consultant similar to our current agreement with S&B (current SCADA support
vender). Vice-Chair Peloza asked that more detail regarding the design, software, hardware
and construction cost allocation of the contract be provided to the Committee. Chairman
Wagner agreed that more detail is needed and suggested postponing Council action until the
detail can be provided by staff. Vice-Chair Peloza supported postponing action by the Council.
Assistant Director/City Engineer Selle asked the Committee to specify the details they would
like to review. Chairman Wagner requested a line item list for the project, similar to a project
bid sheet, listing the tasks and associated costs per task. The Committee and staff discussed
the amount of detailed cost information that can be provided.
In response to Vice-Chair Peloza, Project Engineer Lee verified that the project is funded by the
utility funds.
The Committee and staff reviewed the communications network map. Project Engineer Lee
explained that the communication mode for the new SCADA system is wireless and will no
longer be reliant on land lines.
Chairman Wagner asked what affect the bond funded SCADA project has on utility rates.
Utilities Engineer Repp answered that staff did review the affect on the rate study. Repp
explained that the amount of bond money in the fiscal analysis of the Capital Facilities Program
(CFP) and rate study was higher than the actual $22M coming in from the Build American
Bonds. Repp said that Finance Director Coleman assessed the overall plan and the rate model
and determined that the City could continue to meet its debt coverage and financial obligations
associated with selling the bonds without impacting current utility rates. Chairman Wagner
requested Finance Director Coleman and Utilities Engineer Repp provide the Committee with a
summarized assessment of such at a future meeting separate from a future discussion on
SCADA.
Vice-Chair Peloza asked what company will be installing the system. Project Engineer Lee
answered that the consultant will program and install the system. Utilities Engineer Repp said
that one of the reasons staff selected this particular consultant and design team is because
they have the ability to provide 24/7 maintenance as well as design and installation. Project
Engineer Lee explained that a long term maintenance contract is not part of this Agreement No.
AG-C-401 and that a future maintenance agreement will be considered separately at the
completion of the project. Chairman Wagner stated that the Committee needs some
information as to the cost of maintenance, such as the affect of operating costs that are
normally included in the CFP.
Project Engineer Lee spoke about the security features. Vice-Chair Peloza asked if the new
SCADA system will add security for the pump houses. Assistant Director/City Engineer Selle
answered that there will be security elements included at some of the facilities since the new
SCADA system provides more flexibility to add security elements than the current system.
Assistant Director/City Engineer Selle said that the scope of the project includes some initial
security enhancement at priority sites, but the system can be expanded in the future.
Vice-Chair Peloza asked if there were any grant opportunities for the security elements of the
project. Assistant Director/City Engineer Selle stated that there are currently none, but staff
monitors grant opportunities aggressively.

$1,026.18 FOR A TOTAL CONTRACT PRICE OF $704,001.83 WITH SCI INFRASTRUCTURE
LLC AND ACCEPT CONSTRUCTION OF PROJECT NO. CP0819, PEASLEY CANYON ROAD
CULVERT REPLACEMENT PROJECT
Project Engineer Lee answered questions asked by Chairman Wagner regarding the consultant
cost in comparison with the construction cost. Lee explained that the consultant cost was a
little skewed. due to the very competitive and therefore lower than expected bids on the
construction of the project. Assistant Director/City Engineer Selle pointed out that projects with
a lot of complicated environmental permitting usually have a higher proportional consultant cost.
The Committee commended Project Engineer Lee on a well designed and executed project.
Project Engineer Lee explained how the culvert was constructed, in response to questions
asked by Vice-Chair Peloza.
It was moved by Vice-Chair Peloza, seconded by Chairman Wagner, that the Committee

DESIGN UPDATE
Project Engineer Sweeting distributed an. aerial map of the West Valley Highway Improvements
Project overview to the Committee. Sweeting stated that the West Valley Highway
Improvements Project is a roadway improvement project between West Main Street and the
SR-18 on ramp., Sweeting provided background information on the project. It was discussed
that there is a lot of southbound traffic that backs up during the peak hour, blocking the left turn
pocket, creating safety concerns. There is also-an outdated signal at West, Main Street and
West Valley Highway, the roadway is in poor condition, and there are potential drainage issues
along the corridor, which the.project will also address.
Sweeting reported that there was a Transportation Improvement. Board (TIB) grant awarded
that will fund up to $3,000,000 or 60% of the total project cost to improve the roadway.
Project Engineer Sweeting reviewed: the. scope of the project with the Committee. The roadway
will. be widened, extending the left turn-pocket and a center median and center turn-lane will be
added. The project also-includes construction of a bicycle lane and.a sidewalkon the west side
of the roadway. The signal ,at West Main Street will be updated to the new signal standards
and street-lighting will. be installed. The drainage, issues will also be addressed.
Chairman Wagner asked if major tree removal would occur on the hillside. Project Engineer
Sweetinganswered that the strategy for the hillside is to not disturb it as much as possible,
however'there'will be some tree removal on-the east side of the road related to relocating the
existing roadside ditched, but the trees will be replanted as part of the' mitigation.
Chairman Wagner asked if wetland mitigation is required. Sweeting responded that the project
is. not-.in, a wetland area but it is in a wetland buffer area. There will be some on-site mitigation
-for impacts-to the buffer area.
Sweeting stated-that the construction of the ditches is being permitted through the Army Corps
of Engineers, which may affect the project schedule. Staff intends to go out to construction in
'Summer 2011, pending a timely response from the Corps to proceed.
Project Engineer Sweeting described the new Low. Impact Development (LID) stormwater
management techniques that-will be used as part of the project. The project_will include
pervious concrete sidewalks on the west side, a bio-retention swale (rain garden) in the center
median of the roadway, and a compost amended fill slope on the east side of the roadway.
Sweeting answered questions asked by Chairman Wagner regarding how the stormwater will -
drain into the swale in the center median and how the water will be treated as it drains into the
ditch` located on. the"east side.
Assistant Director/City Engineer Selle responded that there are no requirements to monitor the
water quality, but the: City may decided. to do some monitoring to determine the effectiveness of
the 'new LID techniques being used, following questions asked by Chairman Wagner.

There were no additional questions or comments from the Committee.
F. WELL PUMP DIAGNOSES
Utilities Engineer Repp distributed a discussion outline and some maps and drawings'to the
Committee.
F
Utilities Engineer Repp explained that the wells that staff has,currently been dealing with are
Well .2 and Well 6. Repp reviewed the site map and pointed out-the location of the wells. Both
wells are located in the same building and are separated by approximately 33 feet.
p
Utilities Engineer'Repp continued with the well diagnoses summary. The We116`pump was shut
down in October 2009 and staff.pulled the pump and started analysis, in November-2009 to try
to-determine why it stopped_working.- Well 2 was showing similar declines in production as Well
6 and staff shut it down on June 30, 2010. Staff enlisted the help of a consulting firm to assist
in the_ analysis.
The analysis of the pump included hydraulic, mechanical, chemical, electrical and corrosion
components. Utilities Engineer Repp reviewed what was examined under each `component
during the analysis with the Committee. Repp spoke in depth about some of the things that can
cause corrosion to these types of facilities.
Referencing~the drawing on the pump.column, Repp discussed.the findings for Wells 2 and 6.
Repp said that Wells 2 and 6 showed similar types of corrosion,' although the metal loss in Well
2 was not as severe as Well. 6. Repp explained in-detail how damage to the well components
occurred due to multiple.factors originating with-from sand being drawn into the well casing
from the_surrounding soils:
Mayor Lewis asked how long the well assembly had been operational. Utilities Engineer Repp
answered approximately 5 years.
Utilities Engineer Repp discussed the underlying issues that staff believes is causing. the
problems in the wells,, well hydraulics,,sand production, and well capacity. Repp stated that.as
the wells are producing water sand is starting to get stirred up in the aquifer and is getting into
the pumps:
Director Dowdy spoke about the importance of Well 2 and 6 -and their relationship, to Well 7.
Water is needed from either Well 2 "or 6 to be blended with the water from Well 7.
Repp discussed the well casing and pump.design following questions asked by'Chairman
Wagner.' Mayor Lewis asked if the well casing is damaged. Repp explained that the pump
casing within the well casing was damaged. but the surrounding well- casing was not. Repp
showed the Committee, photos. of-the pump and the pump casing attached to the pump.
Chairman Wagner asked if there were other materials that could be used- in the construction of
the,pump.and casing to prevent the corrosion. Repp answered-that the issue is not with the
Page 7'
Public Works Committee Minutes February 7, 2011
DRAFT MINUTES
type of material utilized but there is more of a problem with the sand production and the
hydraulics of the pump itself. In a normally operating well, these issues would not occur.
Assistant Director/City Engineer Selle explained that the problems with the wells are caused by
a combination of the way the water is being pumped, what is happening in the aquifer, and how
hard the well is being used.
Utilities Engineer Repp went over the next steps in correcting the_problems'with the wells.
Repp stated;that the wells are both high production wells and are close in proximity which may
have an influence, over time,- on the wells producing sand. Repp said that staff is currently
examining options for the wells,. taking into account that resiliency and operational flexibility
needs to be. incorporated. These options include a well field concept using more.,wells with
smaller capacities and more separation, between wells to prevent influence of one well on
others nearby and use of variable speed drives.
Utilities Engineer Repp and Water Utility Engineer Lamothe.answered questions asked by
Chairman Wagner regarding the size of the current well field and the water rights.boundary.
Assistant Director/City Engineer Selle and Director Dowdy responded to questions asked by
Vice-Chair Peloza about why Wells 2 and 6 were placed in such close proximity of one another.
The, Committee, and staff discussed possible locations for the wells.' Assistant'Director/City
Engineer Selle pointed out that there will need to be further study and investigation on the
subject.
Mayor Lewis asked if we are currently able to use Well 7 since Wells 2 & 6 are out of
operation? :Director-Dowdy answered that Well 7 is operational and there is a temporary pump
running Well6 that is being utilized to blend with water from Well 7.
Utilities Engineer Repo concluded that the initial analysis and design report supported the
current. configuration of Wells 2 & 6 but.over time it appears aquifer conditions-may have
changed contributing to more sand-moving into the wells.
Repp discussed using the increased capability of the new SCADA system to monitor, and self
diagnose key operating, parameters at the well sites and using SCADA to also monitor and
record useful preventive. maintenance data such as, vibration, heat, arid well drawdown at
varying pump levels.
Utilities Engineer Repp answered questions asked by Chairman Wagner regarding the use of
monitoring. wells.
Assistant Director/City Engineer Selle reviewed the next steps staff will be taking in their
investigation of the-wells.
G. WATER CONSERVATION
Water Utility Engineer Lamothe distributed a. summary of the current water conservation
program. Lamothe_explained that the conservation plan that the City currently has is defined in
the Comprehensive Water Plan, Chapter .8 and that is in compliance with the Department of
Health Water Use Efficiency Rule.
LaMothe provided. a brief background on when the conservation plan was initially developed.
The City of Auburn developed=their first. conservation program as-part of the 1995
Page 8
Public Works Committee Minutes February 7, 2011
.'DRAFT MINUTES
Comprehensive Plan using the guidelines published by the Department of Health in 1994. As
part of the 2001 Comprehensive Plan the City enhanced the program and defined a goal of a
10% reduction in water use by 2005. Between 2000 and. 2007 the City saw a,significant drop in
their per connection ~demand, not the overall demand because the customer base continued to
grow. There were increases in commercial, school, and irrigation use and decreases in single-
family, multi-family, manufacturing, and City accounts. With the current program that runs from
2009-2014 the City's targeted a 1 % reduction per year per connection in water use as a goal.
Mayor Lewis spoke about the need for. conservation and how that affects City revenue. -
Water Utility Engineer Lamothe reviewed the measures the City currently implemented to meet
the Water Use Efficiency Rule for both demand and supply. The measures the City uses to
encourage customers to use water wisely include.defined rates for customer classes, tiered
customer pricing,, utility bills showing consumption history, school outreach and educational
programs, use of.the City website to promote conservation, the low1low shower and faucet
aerators programs, and the WaterSense toilet rebate program. The toilet rebate program was
launched in November 2010, and three applications have been processed. Chairman Wagner
asked what the toilet rebate amount is. Lamothe answered that the rebate is $100 per toilet
with a. maximum of two toilets per customer account.
Water Utility Engineer Lamothe.stated-that the programs implemented by the City are very
much inline with what other municipalities and other agencies.are doing in the area.
Some of the, supply` side measures. are-mandated by the Department of Health and they include
testing of source meters and replacement if needed,-repair and replacement of service meters,
control of water loss and annual leak detection.. Lamothe described some of the lost water that
the City has to account for, such as water used for firefighting.and flushing the lines. Lamothe
reported'that staff completes 75 miles per year of leak detection.
Vice-Chair Peloza asked who is responsible for testing fire hydrants. Water Utility Engineer
Lamothe answered that the Maintenance. and Operations staff is. Mayor Lewis stated that there
is_a very well documented system for testing hydrants, following questions asked by Vice-Chair
Peloza. Vice-Chair Peloza asked"how many hydrants are in the City. Water Utility Engineer
Lamothe stated that she did not know off-hand but the. number of hydrants in the City is posted
on the City's website. Mayor Lewis asked that staff bring an update on hydrant testing be
brought to the Public Works Committee fo'r review.
Chairman Wagner asked if the City's Resource Conservation Manager brings any expertise to
the City's water conservation activities. Water Utility Engineer Lamothe answered that the
Resource Conservation Manager is assisting.with the pump efficiency and energy consumption
side of the City's conservation efforts.
Water Utility Engineer Lamothe answered questions asked by Chairman Wagner regarding the
25% reduction recorded between 2000 and 2007 and the Water Conservation message that is
included in the annual Water Quality Report.
