Dear Gabriel:
The statements of work covered herein are submitted to the City of Corpus Christi Utilities
Department(CCUD) for consideration. These statements will constitute a fee for services
rendered by the Conrad Blucher Institute for Surveying and Science (CBI) at Texas A&M
University- Corpus Christi (TAMUCC). Included is an outline of our scope of work and budget to
continue to maintain operation of environmental monitoring stations in the Oso Creek and
within the City of Corpus Christi under.
PROPOSED SCOPE OF WORK FOR OSO CREEK WATER LEVEL AND CITY OF CORPUS CHRISTI
METEROLOGICAL MONITORING: 2017
SUMMARY
Ten real-time environmental monitoring stations in the Oso Creek and the City of Corpus Christi
will continue to be covered under this agreement. All meteorological monitoring stations will
report air temperature, wind speed,wind direction, liquid precipitation, barometric pressure
and relative humidity. In addition to these parameters, water level stations will report water
level and stage. All data will be available in graphical and tabular format on CBI's website
(http://cbi.tamucc.edu) for the duration of the project period.This proposal covers a period of
3 months.
RESEARCH OBJECTIVES
Oso Creek Water Level Monitoring
Three water level monitoring stations are located on bridges along the Oso Creek at Saratoga
Rd. near Calle Cuernavaca ("'27°43' 18.26" N 97° 27' 28.55" W),Weber Rd. near Yorktown
Blvd. ("27°41' 19.82" N 97° 25' 45.36" W) and at Staples St. near Oso Pkwy. (^'27°39' 24.89" N
97°24' 5.89" W).These stations consist of a Campbell Scientific CS-475 radar water level
sensor, Vaisala WXT-520 weather transmitter, IP modem, Campbell Scientific CR1000
datalogger, and photovoltaic power system and will report water level and stage height, air
temperature, liquid precipitation, barometric pressure and relative humidity.The Oso Creek
water level stations will assist the CCUD in predicting water consumption rates and provide
meteorological information to residents by measuring rainfall and water level.

Corpus Christi Meteorological Monitoring
Seven meteorological stations are located throughout the City of Corpus Christi at TAMUCC(27°
42' 54" N 97° 19' 43" W), Rodd Field Rd near Wooldridge Rd (27°40' 34" N 97° 21' 9" W),
Carmel Pkwy near S Alameda St (27°43' 54" N 97° 22' 40" W), Cedar Pass Dr near Sun Valley Dr
(27° 41' 6" N 97° 25' 0" W), Del-Mar college east campus (27°45' 51" N 97° 24' 15" W),Del-
Mar college west campus (27°46' 24" N 97° 26' 24" W) and in Calallen at the Nueces River
pump station (27°52' 4.2" N 97°37' 54.5" W).These stations consist of a Vaisala WXT-520
weather transmitter, IP modem, Campbell Scientific CR1000 datalogger and a photovoltaic
power system and reports air temperature, wind speed,wind direction, liquid precipitation,
barometric pressure and relative humidity. A webpage is currently being developed to assist
city technicians monitor rainfall at http://www.cbi.tamucc.edu/ccrl/. This webpage will
continue to be developed through the duration of the project period.
STATION SERVICE AND MAINTENANCE
Oso Creek Water Level Monitoring
Regular maintenance on water level stations will be conducted every six months. Leveling by
CBI will be conducted annually during a regular visit at each water level station to ensure
accurate data is being reported. During a leveling site visit, a leveling gun will be used to
accurately measure the horizontal and vertical distance between a fixed point and a point on
the water level sensor so that the sensor location relative to the NAVD88 datum is known.
Leveling site visits will continually monitor and document any drift in the distance from the
fixed point to the water level sensor so that correction can be made to the data if needed. A full
annual inspection will also be made annually during a regular site visit during which the voltage
output of every component on the power system will be checked, pictures of every station
component will be taken, the sensor orientation will be checked and the desiccant will be
replaced.The creek stage height directly below the sensor will also be measured and the stage
offset value will be updated in the water level sensor. One emergency site visit has been
budgeted to repair damaged station components as needed and will be used in the event that
the damaged component prevents proper data collection or transmission.A short summary of
each site visit conducted will be placed on the station's website and publically available at all
times.
Corpus Christi Meteorological Monitoring
Regular maintenance on meteorological stations will be conducted every 12 months. One site
visit has been budgeted by CBI to conduct a full inspection during which the voltage output of
every component on the power system will be checked, pictures of every station component
will be taken and the desiccant will be replaced. One emergency site visit have been budgeted
to repair damaged station components as needed and will be used in the event that the
damaged component prevents proper data collection or transmission. A short summary of each
site visit conducted will be placed on the station's website and publically available at all times.

DATA COLLECTION
Each real-time environmental monitoring station has its own webpage created within the
website http://cbi.tamucc.edu.A custom computer program, written by staff at CBI, polls each
station every six minutes. During a poll, averaged readings from the datalogger will be
requested. The averages are then placed into the CBI database and reported on the station
webpage so that each value will represent a six minute average. All data stored in the CBI
database is publically available on the internet at http://cbi.tamucc.edu and will be available for
retrieval during the duration of the proposal period. CBI staff performs a quality control check
(QC) of all real-time data daily. During a QC, the data will be checked for missing transmissions
and data anomalies such as readings outside of a feasible range, readings of a constant value,
random spikes, etc. Data anomalies, suspect data, missed transmissions and other factors
affecting the data will be posted as a message on each station's webpage.
INSTRUMENT CALIBRATION
Vaisala WXT-520 Weather Transmitter
The Vaisala WXT-520 weather transmitter does not require a regular calibration. However, the
replacement part WXT-PTUSP contains calibration data and will be replaced every two years as
recommended by the manufacturer for accurate data collection.
Campbell Scientific CS475 Radar Water Level Sensor
The Campbell Scientific CS475 Radar Water Level Sensor does not require a regular calibration.
However, the sensor will be checked for accuracy during annual inspections and will be sent
back to the manufacturer for a quality check if the data provided by the sensor becomes
suspect.
REPLACEMENT PARTS AND EQUIPMENT
TAMUCC owns and maintains the instrumentation and equipment purchased with funds from
this project. In the case of damage,TAMUCC will repair or replace instrumentation as needed
to ensure a continuous data collection record as long as enough funds are available. If not
enough funds are available, the CCUD will be responsible for replacement or repair of
instruments. Replacement equipment will be purchased for this project and kept in inventory
until needed. If additional replacement equipment beyond what is kept in inventory is needed,
every effort will be made by CBI and the CCUD to replace needed components.
COLLABORATATIVE MONITORING
This proposed installation and maintenance of environmental monitoring stations will be
designed to provide data to support those research efforts currently being done by the CCUD
and the Nueces River Authority(NRA). The CBI will work with staff at the CCUD and NRA to
Amend. No. 7
Exhibit A

provide data, information, instructions, etc. that will help them gather the resources needed to
conduct research. Should the need or occasion arise where additional monitoring efforts are
required, CBI will be in a position to support those efforts.
