PUBLIC WORKS COMMITTEE 2015/01/21 MinutesPUBLIC WORKS COMMITTEE MEETING
WEDNESDAY, JANUARY 21, 2015 – 6:00 P.M.
MUNICIPAL SERVICES BUILDING – 800 N. FIELD DRIVE
AGENDA
I. ROLL CALL/CALL TO ORDER: Chairman Cathy Waldeck called the meeting of the
Public Works Committee to order at 6:10 p.m. Aldermen Stanford Tack and
Michelle Moreno were present.
Staff in attendance included Robert Ells, Superintendent of Engineering; Dan
Martin, Superintendent of Public Works; Michael Thomas, Director of Public Works;
Charlie Douglas, Assistant Chief Water Plant Operator; John Gulledge, Supervisor
of Water & Sewer Utilities; Donna Dunn, Assistant to the Director of Public Works;
Chuck Myers, Superintendent of Parks and Forestry; and Robert Kiely, City
Manager.
Also in attendance were Douglas Crampton, Wiss, Janney, Elstner Associates;
Brian Hackman, Strand Associates; and members of the public Charlie
Kohlmeyer and Walter Hamann.
II. APPROVAL OF THE DECEMBER 10, 2014 PUBLIC WORKS COMMITTEE MEETING
MINUTES: Alderman Moreno moved to approve the minutes of the December 10,
2014 Public Works Committee meeting as written. Alderman Tack seconded the
motion, which carried unanimously.
III. WESTLEIGH ROAD BRIDGE OPTIONS: Director of Public Works Michael Thomas
introduced Doug Crampton of Wiss Janney Elstner Associates. Mr. Crampton
explained that a Westleigh Road Bridge Condition Study was performed in the
fall of 2014 and reviewed the report which included safety concerns, aesthetic
improvements, and maintenance items. According to Mr. Crampton, the safety
concerns for the Westleigh Road Bridge were minor. There is concrete
deterioration from the freeze/thaw cycles on the bridge abutments and the
debris on the stairway is a trip hazard.
Mr. Crampton then reviewed the potential aesthetic improvements, which
involved improving the appearance of the paint coatings, moisture staining, and
corrosion staining.
Finally, Mr. Crampton discussed the maintenance items under consideration for
this bridge, which included the freeze/thaw damage, the missing paint on the

steel structure system, moisture staining, concrete deterioration, and the
membrane protection for the bridge deck that has significantly deteriorated.
Additionally, the pedestrian railing is losing support at the base and this may
create a safety concern at some point in the future.
Following the overview of the report, Mr. Crampton reviewed several different
options with the Committee. In Option 1, 7,500 square feet of the outside faces
of the bridge would undergo aesthetic improvements. This would not include
the fascia girder facing each other in between the two bridges. Option 2 would
expand the aesthetic improvements to 15,000 square feet of the bridge face. A
separate option involved the conversion of the northwest stairwell to a
planter/vegetation.
Improvements to the Westleigh Road Bridge could be completed in phases: the
first phase being aesthetic improvements, the second phase being interim
maintenance such as the railing and concrete repairs, and the third being the
full rehab or superstructure replacement.
Mr. Crampton added that the aesthetic improvements would begin with
abrasive blasting and then coating of the concrete surface. There are a number
of options available for coating the concrete surface to include silane sealer,
anti-graffiti coatings, silane-based anti-graffiti coatings, concrete stain, and
breathable paint.
Alderman Moreno questioned the possibility of allowing an artist to showcase
their artwork on the bridge in the form of a mural. Chairman Waldeck added
that the Committee and City Council would need to decide if they want the
bridge to blend in or stand out. If they decided that they would want it to stand
out, they would have to go “all in”.
Cost estimates for the different options were also presented to the Committee.
Option 1 (7,500 sq. ft.) $45,000 - $55,000
Option 2 (15,000 sq. ft.) $80,000 - $95,000
Stairwell Planter Conversion $10,000 - $30,000
Plans, Specs, and Coordination $15,000
Director Thomas explained that the expenditures presented to the Committee
are not currently included in the FY2016 Capital Plan. The study was done
because residents in the Whispering Oaks area have complained about the
appearance of this bridge. Option 1 addresses the issues raised by Aldermen
Pandaleon and Moore; however, maintenance items in the other phases
presented will need to be added into the future Capital Plan.

In reviewing the different options, Mr. Crampton explained that the proposal for
aesthetic improvements to 7,500 square feet of the bridge is the minimum the
City would want to do in order to be cost effective. However, until the
membrane roof is repaired, water will continue to drip down and continue
staining the concrete that was just cleaned and/or repaired. The Committee
asked about the expected life of Option 1. Mr. Crampton replied that they
would expect to get 7 – 10 years out of Option 1, and further explained that this
work would not have to be redone in other phases of the bridge improvements.
Director Thomas added that Aldermen Pandaleon and Moore will receive Mr.
Crampton’s report to review. The Westleigh Road Bridge will be an item for
Council to consider through this and next year’s budget process. Additionally,
staff will investigate if grant funding is available to replace the bridge. The
Committee noted that the bridge could potentially have historical significance,
which would need to be considered if replacement is pursued.
No action was required.
IV. WATER PLANT UPDATE: Brian Hackman of Strand Associates provided the
Committee with an update on information requested at the December meeting,
to include annual historical flows, probable costs for a third option based on
historical flows, and anticipated project time and probable expenditures.
The Committee was presented Option 3, which considers the cost to expand
based on demand. Mr. Hackman reviewed the historical flow data and
described how each option impacts the level of confidence in meeting future
demands. He explained that Option 3B would meet the demand on
approximately 96% of the days, while Option 3C meets the demand 100% of the
time.
Mr. Hackman then presented a breakdown of probable costs for Options 1
through 3C and provided a detailed breakdown for Manufacturer A, B, C, and
D.
The Committee discussed the possibility of installing the infrastructure, while not
purchasing all the modules. This would allow future City Council members to
gradually increase the capacity of the Plant and budget for those expenditures
as needed. The Committee acknowledged the impact of irrigation systems on
the water system, but agreed that they are more comfortable recommending
an 11.4 MGD system with the option to expand than recommending a 14 MGD
system when that demand has not yet occurred. At minimum, the Committee
would like to see Option 3B because it meets the current demands and provides
future expansion possibilities. Mr. Hackman reviewed how minimally the water
rates were impacted between Option 3B and Option 3C.

The Committee further discussed the impact of water rates based on a $7.1
million bond issue versus a $9.5 million bond issue. The Committee asked what
the average rate increase is each year. In a chart provided by Finance Director
Elizabeth Holleb, City Manager Robert Kiely replied that water rates typically
increase 2.5% – 3% each year. However, several years ago when the new Water
Plant went online, there were years with 7% increases. Alderman Tack suggested
that the fixed rate be increased to compensate for Option 3A and the per
gallon rate be increased to compensate for the additional capacity. He
believed that the infrastructure within the plant is for all residents, but the extra
capacity is necessary for those residents who choose to irrigate and use more
gallons of water per month.
Mr. Hackman reviewed the project timeline and probable budget. City Council
approvals would be required on May 18, 2015; January 16, 2016; and April 17,
2017.
Staff’s recommendation was to select Option 3B at 11.4 MGD with a bid
alternative for Option 3A. The proposal and recommendation would be
presented to the City Council at their March 9, 2015 Budget Meeting. Design
would start in May 2015. Non-membrane system items would be budgeted for
and addressed beginning in FY2019. The Committee supported staff’s
recommendation as presented and added that public relations regarding this
decision for the Plant will be important.
V. MAILBOX REIMBURSEMENT POLICY: Assistant to the Director of Public Works Donna
Dunn reviewed the current policy for mailbox replacement/reimbursement due
to snow plow damage and historical data from previous winters. The current
policy is that the City will repair or replace mailboxes with a standard post and
standard black mailbox if damaged by a City snow plow. Residents can also
purchase their own mailbox and be reimbursed up to $50. Staff has received
complaints regarding the low reimbursement amount and asked the Committee
if they felt the policy should be changed.
The Committee asked staff how many of the damaged mailboxes are recurring.
Director Thomas replied that several have been damaged more than once.
Due to this, Public Works’ crews will evaluate damaged mailboxes in the spring to
determine if the post should be moved back from the curb. In some locations,
the mailboxes are placed too close to the road; in other cases, it’s simply the
weight of the snow that damages the mailbox as it comes off the plow.
After group discussion, the Committee did not recommend a change in the
current policy. However, the Committee recommended that staff post

information and a diagram on the City’s website regarding proper mailbox
placement.
VI. EAB FUNDING REQUEST: Superintendent of Parks and Forestry Chuck Myers
provided a brief update on the status of Emerald Ash Borer tree removals. Of the
7,227 ash trees, half have been removed. There are 650 trees being treated. The
1,263 trees that have been tagged are those with heavy infestation and are a
safety concern. Mr. Myers explained that they have expended all the budgeted
funds for FY2015 and no further funds are available to continue removals until
May 2015. Due to the nature of the disease and the safety concern these trees
pose, staff is requesting funding now. The City received favorable bids to aid in
removals, which was scheduled for FY2016. Staff requests that $160,000 from
FY2016 be made available in FY2015 in order to keep up with EAB removals. Mr.
Myers explained that this accelerated plan has been discussed with and
approved by City Manager Kiely and Finance Director Holleb. The proposed
plan will provide a $100,000 savings overall, even though additional money is
being requested up front. If the accelerated plan is approved, most of the trees
will be removed by this time next year.
With the requested funding, the remaining 1,263 tagged trees in Wards 1, 2, and
3 would be removed by Kinnucan and Trees-R-Us. Ward 4 trees would be
removed by in-house staff. All removals would occur by May 2015.
Mr. Myers added that the same proposal will be reviewed with the Park &
Recreation Board next week. The request for approval for the Kinnucan and
Trees-R-Us contract will be on the City Council agenda for February 2, 2015.
Finally, additional funding will be requested at the March 9, 2015 budget
meeting.
The Committee discussed public education about tree replacement efforts. Mr.
Myers explained that there will be a delay in tree replacement. Staff will need to
shift from removal efforts to reforestation and replanting, which will be
communicated to residents at some point in the future.
The Public Works Committee supported staff’s recommendation to utilize FY2016
funds in FY2015 to continue EAB tree removal efforts.
VII. OTHER ITEMS: None.
VIII. OPPORTUNITY FOR PUBLIC COMMENT
• Mr. Paul Hamann asked for clarification regarding the non-membrane
expenses discussed for FY2019. Mr. Hackman explained that these non-
Public Works Committee

membrane expenses included chemical feeds, storage facilities, etc.
These are expenses not related to the retrofit that would need to be done
at the Plant regardless of the change in modules/membranes.
• Mr. Paul Hamann also asked about pushing the membrane system harder
versus slower and questioned a higher flux rate. Mr. Hackman explained
that pushing at a higher flux rate, there is a greater potential for fouling
and a lesser life of each module. Proposals include more modules and
lower flux so that the exposure to material is less and therefore lengthens
the life. The same flux was assigned to Options 3A – 3C.
IX. NEXT MEETING – FEBRUARY 18, 2015: Not all Committee members were available
for the proposed meeting on February 18, 2015. Therefore, the Committee will
instead meet on February 11 at 4:00 p.m. at City Hall.
X. ADJOURNMENT: Alderman Moreno moved to adjourn the meeting of the Public
Works Committee at 7:50 p.m. Chairman Waldeck seconded the motion, which
carried unanimously.
Respectfully submitted,
Donna Dunn
Assistant to the Director of Public Works
