DEPARTMENTAL CORRESPONDENCE

THRU: Scott Linebaugh, City Manager //—
FROM: City Engineer
SUBJECT: Overall Design Report
Recommended Routing
DATE: February 13, 1991
McGoodwin, Williams, and Yates has presented the final Overall
Design Report for the 36 -Inch Transmission Line and Storage
Facilities which was authorized in July of 1991. The purpose of the
Study was to establish primary design responsibility for the
project, and to provide the information necessary to make a
decision between an eastern and western routing for the line.
The eastern route involves following as closely as possible
the route of the existing 36" line utilizing existing right of way
as much as possible until the north edge of Fayetteville was
reached. Then the routing goes across the north part of the city
to a point west of Highway 71 and then south to the proposed
storage tanks south of Highway 62.
The western route follows the existing line to a point north
of Springdale and then crosses over to the west side of Highway 71.
From that point the routing generally follows along the west side
of Highway 71 to the proposed storage facilities south of Highway
62.
Attached to this memorandum is a copy of the Recommendations
section of the Overall Design Study which sets out McGoodwints
recommendation on the routing of the line and gives the associated
costs. Also attached is a small scale plat which shows the eastern
and western routing as described above. The McGoodwin Report
recommends that the City construct the new pipeline along the
eastern route. generally following the routing as indicated on the
attached plat. Their reasons for this recommendation are:
1. Surge protection can easily be provided for
by a tie to the existing surge tank on
Fitzgerald Mountain.
2. Much of the right of way required for the
project was obtained during original
construction.
3. The opportunity exists for ties across the
north part of Fayetteville which will signifi-
cantly improve system reliability and fire
flows.
4. The eastern route is the least expensive
•route by some $200,000.00.
As noted above, the cost difference is minimal (less than 2
percent) between the two routes and should not be a major factor
in the decision making process. That being the case, the
considerations that drive the decision should be factors such as
the ease of implementation, how the line location affects the rest
of the system, and future tie-ins and connections to the line.
The discussion given below of these factors does not include
the line south of the intersection of Mt. Comfort Road and Highway
71 Bypass since that route is common to both alternatives.
EASE OF IMPLEMENTATION:
It would appear that since we already have many of the
easements on the existing route that there would be fewer permanent
easements to acquire utilizing the eastern route, making the
acquisition process of shorter duration and less expensive. Also
the area where most of the new easements would have to be acquired
(across the north.part of Fayetteville) is in our water service
area would tend to make those easements easier to acquire. Along
the western route we would be taking easements that would be of no
benefit at all to the affected property owners. In our opinion the
eastern route would be the easiest to implement.
SYSTEM TIE-INS:
The western route would have only one point where it would tie
to our system, that is at Highway 112 west of the Hushpuppy
Restaurant. On the eastern routing there would be tie-ins at Joyce.
Street and'Highway 265, Old Missouri Road, Highway 71 Business, and
Highway 112. This would significantly strengthen our system across
that area.
FUTURE TIE-INS:
The western route provides somewhat better access to the
northwest growth area north of Mt. Comfort Road. However, the
eastern routing comes close to that area and could with minor re-
routing provide the same access. Both will provide direct access
to the new Industrial Park. Additionally, the eastern route
provides access to the northeast area of the City and to the
northeast growth area.
Early in the planning process there was a great deal of
discussion of whether a larger line might be constructed along the
western route and access to provided to supply water to either the
City of Springdale or to areas in western Washington County (Siloam
Springs, etc). Beaver Water District was particularly interested
in this kind of arrangement.
The Beaver Water District was not able to put together any
kind of proposal, mainly because the City of Siloam Springs has
already made or is in' the process of making other permanent
arrangements for a water supply and would not be interested in
Beaver Lake water for the foreseeable future. Nor did we get any
indication from Springdale that they would be interested in joining
in on some cost sharing basis with a larger line.
Based on the recommendations of McGoodwin, Williams, and Yates
Overall Design Report and on the factors discussed above, the Staff
recommends the construction of a 36" transmission line along the
eastern route.
The Overall Design Report sets out the cost of construction
as follows:
Transmission Line, 36", 30", and 24"
Storage Facilities (12 Million Gallons)
Estimated Right of Way costs
Engineering and Contingencies (21%)
TOTAL ESTIMATED COST

$11328,000 $14,040,000
There is a difference of $2,160,000 between the cost given in
the Overall Design Report and the budgeted amount. The reason for
that cost difference is that we did not account for inflation when
developing costs for the CIP. However, after discussions with
McGoodwin, Williams, and Yates we feel due to the contingencies
built into their figures and due to the competitive nature of the
project that there is a very good chance that we will be able to
construct the project within our budgeted figures.
In the event the cost exceeds our budgeted amount, we will
have some funding options open to us. Those options would include
the utilizing of additional pay as you go sales tax money, an
increase in the water and sewer bond issue, and the transfer of
funding from undesignated water projects.

FIGURE NO. 1
• The eastern route provides immediate service to a large industrial tract
northwest of the intersection of U. S. Highway 71 and Arkansas Highway 112.
An additional responsibility of this study was to provide a preliminary design and cost
estimate for storage tanks recommended in the Water Master Planning Study to be
constructed on the north end of Kessler Mountain near U. S. Highway 62. The
preliminary site designated in the Water Master Planning Study proves to be a site on
which two 6 million gallon water storage tanks can be constructed very economically.
Due to the steepness of the north face of Kessler Mountain, it seems impractical to
attempt to develop an access road to the tank site directly off of Hanshew Drive. We
recommend that an agreement be worked out with the land owner near the tank site
that the existing private drive to near the tank site be used as a portion of the access
to the tank site. As shown on Exhibit 3, the total estimated cost of the storage
facilities is $2,300,000.
The Water Master Planning Study dated June 1989 provided a cost estimate for the
eastern route of $12,500,000, and the two 6 million gallon water storage tanks at
$2,400,000. The report sets out that these estimates are based on 1989 values and
thus to compare the 1989 estimated cost with the cost as estimated by this study, we
have adjusted the 1989 cost with a five percent per year adjustment in order to
compare today's cost estimate with the 1989 projection. This calculation is shown
below:

As shown above, the total cost estimates for these facilities today are less than the
1989 values adjusted to 1991. We recommend that the City proceed with the
development of plans to construct these facilities as soon as possible.

VI. RECOMMENDATIONS
4:f -
The primary purpose of this study was to make a detailed route selection and a
preliminary design for the possible routes of constructing a new 36 -inch transmission
main between Beaver Water Plant to the southwest part of Fayetteville. These routes
were selected and cost estimates made as heretofore set out in this study. As set out
In the previous section, the estimated cost of the eastern route is $13,900,000, while
the estimated cost of the western route is $14,100,000, or about $200,000 more
expensive.
It is our recommendation that the City construct the pipeline along the eastern route
for the following reasons:
•
•
The pipeline can be* tied directly to an existing surge tank on Fitzgerald
Mountain, which affords an almost fool -proof surge protection for the pipeline.
While the projected surges along the western route are not excessive, there is
no economically feasible opportunity along the route to construct a comparable
surge tank facility.
Permanent easements for most of the first 50,000 feet of the pipeline were
acquired during the construction of the initial pipeline. Additional permanent
right-of-way will need to be acquired along a portion of this section of the
pipeline as well as temporary construction easements throughout its entire
length.
The western route will require acquisition of permanent right-of-way for its
entire length.
A portion of the eastern route (see Figures 1 and 4) will be constructed across
the northern part of the City, roughly paralleling Joyce Street from Crossover
Road to U. S. Highway 71.13, and proceeding on west to near the Hush Puppy
Restaurant, then south along U. S. Highway 71. to Mount Comfort Road. This
section of pipeline crosses several major feeder lines (such as a 16 -inch main
near the Intersection of Joyce Street and U. S. Highway 7113) throughout its
entire length. These ties significantly improve system reliability and fire flows
across the northern section of the City in the event of shutdown of any of the
lines to which it can be tied.
Based on our cost estimate to construct this facility, it is $200,000 less than
the western route.
