RINCON BAYOU DIVERSION PROJECT-
BIOLOGICAL MONITORING: 2006-2007
CONTRACT FOR SERVICES
The City of Corpus Chnstl, Texas, hereinafter called "City", and the Harte Research Institute at Texas
':"'&M University - Corpus Christi hereinafter called "Harte", hereby agree as follows:
SERVICES TO BE PERFORMED
Harte hereby agrees to perform all consulting services necessary to plan develop, undertake, complete, and
ceport the results of a studv for
· Biological monitorirlg at three (3) locations as described in the "Research Contract Proposal titled
'Rincon Bayou Diversion ProJect, Biological Monitoring, Year 6 2006 - 2007 dated September 5,
2006.
SCOPE OF SERVICES
HARTE's services will be those necessary to provide the monitoring required deliver an annual written report
cOITesponding to the major tasks outlined in the Research Proposal dated September 5, 2006. Harte will
,complete the tasks set forth by Section II A as set forth in the research proposal attached as Exhibit A.
TASKS
Rincon Bavou Monltorin9.::
The monitoring will assist In the
· Determination of whether any harm occurs as the result of freshwater diversion from the Nueces
River Into Rincon Bayou
· Assessment of the benefits of the diversion on primary and secondary productivity in Rincon Bayou;
and
· Development of an optimal oDerational management procedure for freshwater pass-through based on
sound scientifiC baSIS.
Tasks to be completed Include monthly
· Benthic sampling and collection of phytoplankton biomass (chlorophyll a) and water chemistry (e.g.,
nutnents salinity, & temperature) for analysis by UTMSI; and
· Determination and comparison of biomass, abundance, density, diversity, and species distribution of
benthic Infauna in Rincon Bayou for relevant changes in water quality (e.g., salinity) and soil
cnaractienstlcs (eg sediment grain size)
Ej RESEARCH PLAN AND METHODS
The specific research plan and methods for the 2006 - 2007 monitoring period are set forth in the Research
CO'ltract Proposal incorporated as E<hibit A of this contract.
PRODUCTS
Harte Will deliver an annual written report by January 2008. The annual report will be written by the principal
Investigators. Harte Will not change the principal investigators without notifying the City of the proposed
replacement and receiving \Nritten approval from the City The City will not unreasonably withhold approval.
The comprehensive annual report WII describe the results of the tasks associated with the Rincon Bayou and
Allison 'Nastewater DiverSion Findings will be integrated and presented to assess the current status of the
estuarine ecosystem of the Nueces Delta. All annual reports will be technical reports of the Harte Research
Institute at Texas A&M Unl'/ersity-Corpus Christi. The principal investigators involved with this project will
assist the City of Corpus Christi, either through written or personal communication or direct presentation to the
Texas Commission on Envir.onmental Quality, should any proposed changes to the work plan be necessary.
Pnncipal'nvestigators will participate in any meetings necessary to allow the City to coordinate the findings
with other studies prepared by separate contract.
