We are continuing on the design of the project, and should be acquiring a grading
permit in February.
b. White River Use Attainability Analysis (Minerals)
As discussed previously, there is a relatively strong indication that the EPA is likely
going to look at the issue of appropriate levels of minerals and appropriate methods for
determining those levels on a national scale over the next several years. We will likely
hold a meeting with ADEQ in the first part of 2015 to clarify the expectations of the
Department.

system requires full evaluation every 10 to 15 years. These evaluations and
subsequent repairs will prevent future sanitary sewer overflows (SSOs) and help
protect the environment and the City. This project will include field investigations and
the development of recommended sewer improvements. The proposed services are
not to exceed $1,116,251. This item will be presented at the January 20th Council
Meeting.
6. New Business
a. 1-49 & Garland Water and Sewer Relocation Design, Professional Engineering
Services Contract Garver, LLC
The 1-49 & Garland water and sewer relocation design is required for the planned
AHTD interchange improvements (Job BB0414). Garver LLC was selected by a
formal Engineering Selection Committee to perform the design of the water and sewer
relocations associated with the interchange construction. A preliminary phase contract
($19,500.00)was approved January 7, 2015. Another contract, for final design, is
anticipated for the February 17, 2015 City Council meeting and will be discussed at the
Water/Sewer Meeting February 10, 2015 (after Agenda session). The design is
required by AHTD no later than April 1, 2015. The water and sewer relocation costs
appear to be eligible for reimbursement from AHTD.

c. Storm Water Monitoring
Multiple options have been researched regarding stormwater sampling at one or two
major streams within Fayetteville. Please find attached documents showing the various
options available through the USGS as well as a memorandum describing each option
with the staff recommendation. Essentially staff would recommend a system that would
allow for continuous monitoring of major constituents including flow, temperature,
specific conductivity and turbidity. These constituents would allow for the estimation of
other pollutants due to the relationship that will be established by physically sampling the
locations 12X/year for a broad range of the identified pollutants (i.e. various seasons,
storm events, flows, etc...) Provided two locations are chosen, east and west sides of
town, the proposed service through USGS would total $71,721. The USGS has
proposed to include $10,000 of funding which would bring the City total to $61,721. The
City's portion of the monitoring station on Town Branch to the east would be a total of
$26,513 and a station on the west would total $33,808. The remaining cost would
include a crest stage gauge on Niokaska Creek at Township and would total $1,400.
Due to the fact both divisions benefit, it is proposed to split the City's portion 50/50
between Engineering and Water& Sewer Divisions. This would be a total cost of
$30,860.50 per division.

L PY l le STAFF MEMO
ARKANSAS
TO: Water and Sewer Commission
THRU: Don Marr
Jeremy Pate
Chris Brown
FROM: Alan Pugh
DATE: January 8, 2015
SUBJECT: Approval of the 2015 USGS Contract for stream gage installation and
monitoring as well as water quality sampling and monitoring for various outfall locations
for the City of Fayetteville
RECOMMENDATION:
Staff Recommends approval of the 2015 USGS Contract for stream gage installation and
monitoring as well as water quality sampling and monitoring for various outfall locations for the
City of Fayetteville.
BACKGROUND:
The City of Fayetteville has historically contracted with USGS to operate and maintain three
urban stream gages. These gages are located at Mullins Branch at Martin Luther King Blvd,
Town Branch at Highway 16 and Niokaska Creek at Township Avenue. This program has not
included any water quality sampling at these locations in the past. The gauging stations strictly
monitor flow and generate hydrographs for various storm events. The information produced by
the gages can be viewed on the USGS website by following:
http://waterwatch.usgs.gov/?m=real&r=ar
In 2014 the City of Fayetteville contributed $21,528 to the stream gage program and the USGS
contributing $5,802 in funds. If no changes to the program are required, the same funding
levels are being proposed for 2015.
DISCUSSION:
In an effort to further quantify potential pollutants to some of the main tributaries of Fayetteville,
a revision to the USGS contract that would include at least one new stream gage and water
quality monitoring. The associated water quality monitoring could be periodic or continuous.
USGS has provided pricing for each of the requested scenarios. The scenarios with the
associated pricing can be found on the attached spreadsheet and generally described below:
• Scenario 1: No change to current contract.
• Scenario 2 TB: Includes a continuous record stream gage on Town Branch with
sampling six (6) times per year for various constituents and two (2) times per year during
storm events for a total of 8 samples. USGS will compute annual sediment and nutrient
loads using the LOADEST program.
Mailing Address:

Fayetteville,AR 72701
• Scenario 3 TB: Includes continuous record stream gage on Town Branch with sampling
twelve (12) times per year. This sampling would be in an effort to establish continuous
water quality monitoring for temperature, specific conductivity and turbidity. USGS will
compute annual sediment load using surrogate relationship w/turbidity; compute annual
nutrient loads using LOADEST program.
• Scenario 2 ALT: Same as Scenario 2 for Town Branch, however, City could pick a
second location on the west side of town. The cost listed would be in addition to the cost
associated with the option selected for Town Branch. USGS will compute annual
sediment and nutrient loads using the LOADEST program.
• Scenario 3 ALT: Same as Scenario 3 for Town Branch, however, City could pick a
second location on the west side of town. The cost listed would be in addition to the cost
associated with the option selected for Town Branch. USGS will compute annual
sediment load using surrogate relationship w/turbidity; compute annual nutrient loads
using LOADEST program.
• Single Storm Sampling: Additional cost if sampling in scenarios above is complete and
the City would like additional sampling.
As noted, Scenarios 2 and 3 above include operating the three (3) existing stream gages as
"crest-stage gaging stations." Elimination of these gages could reduce the listed cost by
approximately$4,200.
Staff would recommend approval of Scenario 3 TB and Scenario 3 ALT as well as maintaining a
crest stage gauge on Niokaska Creek at Township. This recommendation would allow the City
to monitor two of its major outfall locations for both flow and pollutant loading. The station
located on Town Branch would monitor a largely developed area that discharges into the West
Fork of the White River which currently has Total Maximum Daily Load (TMDL) defined by
ADEQ for turbidity. Monitoring just upstream of the West Fork would allow the City to determine
Fayetteville's contribution to this TMDL. While no waste load allocation (WLA) has been set for
Fayetteville, it would be beneficial to have a base line measurement in the event ADEQ sets a
WLA.
Staff would also recommend a second gauge to be located on the west side of town. The
current locations being considered are Clabber Creek at Wheeler Road or Mud Creek at Greg
Street and would also provide information as to any contribution from portions of the City to the
overall amount of pollutants to the Illinois River. As you may be aware, the Illinois River
phosphorus concentration is currently under dispute between the States of Arkansas and
Oklahoma. Pending the outcome of this litigation, additional enforcement measures may be
placed on Arkansas municipalities regulating both point and non-point source pollution. Again, it
would be beneficial to have a base line from which to judge the set TMDL as well as monitor the
progress of measures developed to reduce pollutants.
In addition to the items above, staff would also recommend maintaining a crest stage gauge on
Niokaska Creek at Township. This gauge has been useful in the past in determining the
intensity of storm events and the extent of any flooding that they caused.
The total cost for the recommended program described above would be $71,721 with the USGS
contributing $10,000 in Cooperative Funding for a total cost to the City of Fayetteville of
$61,721. In addition to the Cooperative Funds, the USGS is proposing to provide and install the
equipment at no cost to the City.
2
BUDGET/STAFF IMPACT:
As stated the total cost of the program would be $71,721 with the USGS contributing $10,000 in
funding. The remaining $61,721 would be split between the Engineering Division and the Water
and Sewer Department. As the information collected would benefit both departments equally, it
is proposed to split the required funds 50/50 between the two divisions or a total of$30,860.50
each.
