Honorable President
and Members of the City Council,
Transmitted herewith is a Resolution approving a Joint Funding Agreement and Proposal for
Green Infrastructure Monitoring between the City Of Omaha and the United States Department of
the Interior, U.S. Geological Survey (USGS).
This Agreement provides for continued monitoring of the water balance of storm water runoff
through a rain garden test site currently located at the Public Works Department's Sewer
Maintenance Facility, located at 6880 Q Street. The Proposal provides the scope for obtaining
this quantitative data which would provide both the means to meet certain regulatory requirements
and additional data needed for the continuous management of the storm water management plan.
The USGS will provide data monitoring, validation and publication, as,well as a portion of the
project costs. The City will pay its local share, in the amount of,$29,700.06, as.a lump sum from
the Storm Water Fee Revenue Fund 12128, Storm Water Management Organization 116312,
year 2019 funding..
The Public Works Department requests your consideration and approval of the attached
Resolution and Joint Funding Agreement.
Respectfully submitted, Referred to City Council for Consideration:

Dear Mr. Kee:
•
Enclosed are two copies of Supplemental Joint Funding Agreement No. 18EMNE000210.
Mod 001 for the Green Infrastructure Monitoring project at the sewer and maintenance facility
in Omaha,NE.This modification will provide funding for an additional year of monitoring
and data collection in the bioretention cell. The total amount of the agreement is increased by •
$36,300 or$6,600 for the U.S. Geological Survey and$29,700 for the City of Omaha. The
end date has been extended until December 31, 2019. Please sign both copies of the
agreement and return one to this office as soon as possible. The second copy is for your
records. Work cannot be continued until we receive the signed agreement.
Work performed with funds from this agreement will be conducted on a fixed-price basis
under the authority of statute 43 USC 36C. Billings will be rendered quarterly. The results of
all work under this agreement will be available for publication by the U.S. Geological Survey.
Please contact Brent Hall at 402-328-4121 if you have any questions concerning this
agreement.

BACKGROUND/INTRODUCTION
Stormwater management methodologies are shifting from the traditional detention
basin to a more green-infrastructure approach that stresses the importance of capturing,
retaining, and treating stormwater. The implementation of green infrastructure uses
various Best Management Practices(BMPs)to mitigate the detrimental effects of
stormwater on water quality.A bioretention cell is a BMP that captures and treats
stormwater by evapotranspiration and infiltration,thereby reducing the quantity of
stormwater.Bioretention cells have been used for a number of years in the United States,
and factors such as soil type,vegetation, evaporation rate, and cell design can affect
performance. Therefore,monitoring the performance of a local bioretention cell is needed
to evaluate and validate green-infrastructure BMPs.
OBJECTIVES AND SCOPE
The purpose of this project is to monitor the water balance of stormwater runoff
entering a bioretention cell. Inflow, outflow, evapotranspiration(ET), and soil moisture
data will all be measured and transferred to the web near-real time. Data will be collected
on a seasonal basis starting as early as April and ending as late as October and will span
the 2019 federal fiscal year(October 1,2018-September 30,2019)with data approval
and publication occurring in the first quarter of FY 2020. Collected water level and flow
data will go through the established review process and will be published in the USGS
National Water Information System(NWIS)online database.
APPROACH .
The water balance will be measured in the bioretention cell in the following
manner: inflow into the bioretention cell will be measured by a cutthroat flume at the
swale entrance, and by a Palmer Bowlus flume for the flow entering the cells through the
pervious pavers. Potential evapotranspiration(ET0)will be measured by a Campbell
Scientific ET107. The movement of water in the soil will be monitored by an array of soil
moisture probes nested at various depths. Flow out of the cell will be measured by a
Palmer Bowlus flume installed on the underdrain pipe.To measure the flow leaving the
cell through the overflow weir, stage in the cell will be measured to determine the depth
of water flowing over the weir.
