CITY COUNCIL AGENDA REPORT

STEVE ALBRECHT, DIRECTOR OF PUBLIC WORKS
CONSIDER APPROVAL OF A RESOLUTION 1) ACCEPTING THE DESIGN
REPORT AND 2) AUTHORIZING PREPARATION OF PLANS AND
SPECIFICATIONS FOR THE WATER TREATMENT FACILITY
Introduction
The purpose of this agenda item is for the City Council to accept the design
report and authorize preparation of plans and specifications for the Water
Treatment Facility.
Historv
On August 7, 2006 the City Council approved the City's Standardized Contract
with Bolton & Menk, Inc. for the Water Treatment Facility Design. The initial
phase of the project, the design report was initiated that night.
As part of the design report preparation, the Water Treatment Facility
Committee (WTFC) and the consultant completed a public involvement
process. Meetings were held on September 6th, October 11th and November
2nd. In excess of 500 notices were mailed for each meeting. Additionally three
newsletters have also been sent out to area residents. Turnout at the
meetings has been confined to the residents living adjacent to the site.
During the last meeting held at the WTF site the outer perimeter of the building
was staked for residents to view and computer generated images were used to
show the view from different yards.
The results of the public involvement process are contained in the report. The
neighborhood's preference was for a building that had a residential feel and
utilized landscaping for screening and filtering of the building.
The WTFC feels that the preliminary concept design contained in the design
report achieves these goals while balancing the greater communities
concerns of function and budget.
Current Circumstances
The WTF design report has been completed and is attached for City Council
review. Copies of the final concept drawings area also attached to this report.
The proposed timeline for the project is as follows:

ISSUES:
Several issues were raised by the WFTC and the residents during preparation
of the design report.
1) Plant Size
The plant was planned to be 6.5 MGD in the CIP and 2004
Comprehensive Water System Study. However based on the findings
of the Water Supply Plan presented to the City Council on November
20, 2007 City Staff is recommending the oversizing of the plant to
accommodate growth based on the limitations of the City's water
supply west of the lake. Staff is recommending the plant be oversized
to 7.5 MGD. This oversizing will have a negligible impact on the plant
building size and foot print. The additional costs will be funded by
development fees as the direct beneficiary of the expanded capacity.
2) Buildina Desian
The proposed WTF needs a Conditional Use Permit. This permit
requires that the building and landscaping meet certain standards.
The DRC has been updated on the concepts proposed landscaping
and building materials throughout the process to ensure that the
building will meet City requirements. The proposed facility does
exceed the minimum standards and is very similar to Fire Station No. 1
and the Police Station in proposed materials. The area where the
facility discernibly will exceed the design standards is the roof system.
This is discussed in item 3 below.
3) Plant Roof Desian
During the public involvement process the neighbors on the west and
north sides asked the City to bring some residential scale and feel to
the north and west side of the building. In an effort bring a residential
feel to the neighborhood side of the structure a roof option was
included in the design. This roof option will add an estimated $200,000
to the project. The incorporation of this roof does greatly add to the
residential look of the facility and the WFTC does support inclusion of
the roof upgrade to better assimilate the plant into the surrounding
neighborhood.
4) Garaae
The concept plan includes a three bay garage in the facility. This
garage will be used to store the City's Vac Truck, generators and other
water system related equipment. Currently the City's Maintenance
Center is at vehicle capacity. The moving of the City's water system
equipment and Vac Truck to this facility will create additional vehicle
storage in the Mainenance Center. Small garages are part of most
WTF's. The WTF will be the City's nerve center and response point for
the water system and therefore it is appropriate to store necessary
equipment on-site.
5) Facilitv Fencinq
As proposed in the concept drawings the facility will only be fenced on
the south and east sides. The north and west sides of the building are
not accessible and form a wall. Staff does not feel it is necessary to
fence the north and west sides of the property. Currently there is some
fencing on the west side which will be salvage and reused. Concerns
regarding access to the northern part of the site by the public have
been raised. As mentioned above the plant will be secure as proposed
the only purpose of the northern fence is to prevent vandalism and
loitering. This is currently not a problem on site. Staff feels that the
north portion of the site is no different than any park or other public
facility non-secure area which we do not fence. The neighbors support
this fencing plan.
6) Budaet
The City's CIP and 2005 Water Rate Adjustment were based on a $13
million dollar facility. This budget was based on the size and similar
facilities in other communities. This budget included $11 million in
water revenue bonds which are funded by water rates. As part of the
long term strategy to mitigate water rate increases associated with
operation and maintenance of the City's water system, staff is
proposing that the portion of the project funded by water revenue
bonds be limited to $10 million. Staff feels the budget that is discussed
in the next section reflects the City's commitment to meet those goals.
FINANCIAL
IMPACT:
The design report details the estimated and proposed costs for the project.
The estimated project construction costs are as follows:
I
I Estimated Construction Cost
I Design Contingency (1)
Construction Contingency (2)
Admin/EnQineerina/LeaallTesting (3)
Bonding Costs
I
I Total Project Cost $12,656,300
(1) For changes during design and material cost increases
(2) For changes during construction
(3) Includes City Administration Costs of $150,000
6.5 MGD
$10,905,000
$475,000
$200,000
$868,300
$208,000
The proposed funding for the project is as follows:
7.5 MGD
$12,535,000
$475,000 I
$200,000 I
$918,000 I
$208,000
$14,336,000
7.5 MGD I
$2,000,000 I
$2,332,260 I
$10,004,040 I
I
I Total Fundin,.Q $12,656,300 _ $14,336,300 ]
(4) 8% (0.5 MGD) New Development Cost for 6.5 MGD, 20% (1.5 MGD) for 7.5 MGD
I Funding Source
I Water Storage Fund
I Trunk Reserve Fund (4)
I Water Revenue Bonds
I
6.5 MGD
$2,000,000
$798,504
$9,857,796
The above funding shows that the impact to the water rates will be $10 million
or less regardless of which size plant the City builds. This is $1 million less
than was planned for in the CIP and rate study. This is very important as it
allows the City to defer future water rate increases that would be needed for
operation and maintenance of the City's existing water system to 2009. Under
the large plant scenario the Trunk Reserve fund from new development fees
pays for the oversizing of the plant. The oversizing of the plant from 6.5 MGD
to 7.5 MGD increases the design and construction administration costs by
$50,000 for the additional filters and equipment design along with testing and
other construction activities. Both plant options minimize impact to rate
payers as was discussed in the City's Water Supply Plan update at the
November 20th City Council meeting.
Based on the above budget the City Staff and WTFC are recommending
construction of a 7.5 MGD plant.
ALTERNATIVES:
The alternatives are as follows:
1. Accept the design report and approve a resolution authorizing
preparation of plans and specifications for construction of a 7.5 MGD
Water Treatment Facility.
2. Table this agenda item for a specific reason.
3. Deny this agenda item for a specific reason and provide staff with
direction.
RECOMMENDED
MOTION:
Staff recommends alternative number 1.
