professionals to assist the City of Corpus Christi with related projects including potential dredge
operations and/or FEMA reimbursement for storm damage.
1-2. Aerial Photography
Description: Acquisition of an annual set of rectified aerial photographs of the Packery Channel
region including the entire channel from the GIWW to the Gulf of Mexico (GOM); including North
Padre and Mustang Islands from the south end of the seawall to Newport Pass. Photographs are
applied in ArcGIS environment for comparative analysis of change relative to key features and as
a reference for overlay of data and terrain models. Bids received during 2015 show that the cost
of aerial photography is comparable to the 2014 effort.
Purpose: For interpretation of large-scale changes in vegetation, dune line, and inter-tidal regions
adjacent to the inland segment of the channel as well as along Padre and Mustang Islands. In
addition, the aerials are appropriate for visuals and explanation aids to residents and laypersons.
Schedule: (1) annual set conducted Sept/Oct 2015 (pending weather conditions).
Task 2. Measurement of Morphologic change in Packery Channel and along Mustang and
Padre Island.
2-1. Beach Profile Survey
Description: The beach profile survey provides information on changes occurring at 18 specified
locations from the Nueces Kleberg County Line to north of Fish Pass. There are historic data for
these locations since 1995. Elevation measurements are collected along transects that initiate
landward of the dune or other landward limiting feature(seawall or pavement)and extend offshore
up to one mile into the Gulf of Mexico.
Purpose: To document changes in features such as the dune toe (seaward limit of dunes) berm
crest (most landward point of active sediment transport on the beach), and sand bars. The data
are applied to calculate volumetric change along historically surveyed areas of the beach and
sand volume which is required for sand placement and documentation for FEMA funding. Data
is also applied to verify shoreline position data and to determine the maximum region of sheltering
(Zone of Influence) by the jetties.
Schedule: (1)Annual survey conducted during peak summer condition (Sep/Oct 2015).
(3) Intensive surveys of beach nourishment area fronting the North Padre Island
seawall (Sept/Oct 2015 and Feb/March 2016 and June 2016)
2-2. Shoreline Position surveys
Description: Elevation data are collected by RTK GPS across the beach from close to the dune
toe to the water line along a zigzag path. The beach is surveyed from south of the Nueces Kleberg
County Line to north of Fish Pass at Mustang Island State Park.
Purpose: These surveys are an efficient and low-cost way to measure changes in the width of
the dry beach over the broad study area. Within days, a large section of the beach can be
measured to determine changes in shoreline position from which regions of beach erosion and
accretion can be determined and potential "hot spots" can be identified. Monitoring the seasonal
position of the shoreline assists in management of beach vehicular access south of the inlet and
addresses persistent regions of shoreline recession that have been identified fronting the North
Padre Island Seawall and Whitecap Blvd as well as regions of receding shoreline north of the inlet
near Newport Pass.
Schedule: (3) Surveys. Tentative survey schedule: Sep/Oct 2015, Jan/Feb 2016 and June 2016
2-3. Surveys of channel and nearshore depth and morphology (Features of seafloor and
bottom of channel)
Description: These bathymetric surveys combine single-beam and multi-beam sonar coverage
to provide high resolution of morphology (shoals, scour and bars). Seasonal series of data is

•
applied to interpretation of pathways of sediment transport.
Purpose: Data is applied to define features such as shoals (areas of deposition) and scour(areas
of erosion) in the channel, nearshore and around structures. This data is applied to determine
pathways of sediment transport and to calculate volumetric change for application to the
estimation of the sand volume available for dredging. The data are applied to interpret trends in
sediment transport as well as to calculate volumetric change of sand, for nourishment projects,
and to identify potential regions of shoaling which could limit navigation. A primary application of
this data is to assist with determining potential scheduling of dredging.
Schedule: (3) Surveys. Tentative survey schedule: Sep/Oct 2015, Jan/Feb 2016 and June 2016.
(abbreviated — Basin to Gulf only). Additional surveys may be required if data indicate that depth-
limited navigation is imminent.
2-4. Inland Channel Segment and Mollie Beattie Coastal Habitat Community (MBCHC)
Description: The inland channel segment bordering MBCHC continues to modify as the region
adjusts to changes in water flow in the channel and over the wetland. These changes are best
captured seasonally through a network of cross-sections that document changes in wetland
extent, channel boundaries and shoreline change. Elevation is measured along transects (survey
lines) roughly perpendicular to channel orientation starting at the location of mean higher high
water (MHHW) shoreline position along the south shore and then extending across the channel
to the location of MHHW shoreline position or until a limiting feature (such as coverage of a raised
placement area) is defined. Measure the MHHW shoreline position along the south shore of
Packery Channel from the HWY 361 Bridge to the Relief Channel west of the channel dog leg.
Purpose: These surveys define change in the inland segment of the channel that borders the
MBCHC and changes in the elevation of the wetland. Analysis of these data sets provide
quantification of change in primary (-5 ft) and upper bank (MSL) width along MBCHC. In addition
the MHHW position of the west side of the inland channel segment (residential) is surveyed and
compared to previous surveys to determine historic change in position.
Schedule: (2) Survey Sets (Transects and MHHW). Tentative survey schedule: Sept/Oct 2015,
Jan/Feb 2016. Additional surveys may be required if data indicate that the rate of change has
increased during the study period.
2-5. Event/Storm or Environmental Engineer Support Surveys
Description: In a continued effort to respond to reported City of Corpus Christi budgetary
constraints, the monitoring program continues at a modified schedule to include (2) seasonal
surveys (Sept/Oct 2015 and Jan/Feb 2016) and (1)transitional reduced-cost survey (June 2016).
To accommodate monitoring concerns beyond these seasonal surveys this task provides for
event survey or other survey requirements as needed. Such support outside of seasonal surveys
could include but is not limited to dredge support, engineering support, environmental assessment
(wetland), and sand placement activities outside the seasonal survey scope. The primary
purpose of the event surveys is to facilitate timely pre- or post- storm surveys. Surveys may be
needed beyond the seasonal designation, such as after storms, and to assist with the
investigation of sensitive environmental habitat or anthropogenic influences on the coastal
environment that are identified during the course of the three seasonal surveys. The cost is based
upon the following survey suite but may be utilized as needed.
An additional line item is the maintenance of the water current monitoring stations in the GIWW
and Packery Channel. Monitoring changes in current flow provides data for future studies of
hydrodynamic change potentially associated with the addition of channels in the Lake Padre
Island region of the study area. See Exhibit A.

Packery Channel Monitoring Program
Amendment #11 (2015/16)
Purpose
To continue to protect the City of Corpus Christi's vested interest in the inlet, beach (Mustang
and North Padre Island), and sensitive habitat that comprise the Packery Channel System. This
program supports the City of Corpus Christi's pro-active approach to research-based
management of this system.
The monitoring program consists of three seasonal investigations of shoaling and scour in the
channel and nearshore (Gulf of Mexico) as well as changes in the width/depth of the inland
channel segment and beach width/volume as related to:
• Post-dredge and post-nourishment monitoring
• Future dredge planning and support
• Navigation safety and placement of aids to navigation where required
• Beach nourishment planning and support
• Sensitive habitat management at the Mollie Beattie Coastal Habitat Community
(MBCHC)
• FEMA reimbursement documentation
• Data acquisition for application of structural stability assessment (coastal structures:
jetties, revetment, bridge scour protection)
• Public awareness and community education/outreach
• Support and collaboration on vicinity coastal projects and concerns.
Focus of Monitoring Year 2015/2016
Monitoring and analysis will continue to focus on both the channel mouth and nourished region
along the North Padre Island Seawall during 2015/2016. The following are specific areas of
concern/interest over the next monitoring year.
• Entrance Channel Shoal and Navigation
Monitor changes in area of transient and persistent localized shoaling in the entrance
channel that has previously stimulated two previous Notice to Mariners to be
recommended (Sep 2011 and July 2014).
• Reduction in Scour at Mouth and Potential for Ebbshoal Development
An additional region of concern is located in the nearshore surrounding the channel
mouth where ebbshoal development is monitored. No persistent shoaling has been
identified at the channel mouth but transient shoals and bypass bar formation have
repeatedly developed seasonally and in response to seasonal forcing and events such as
Hurricane Ike. In addition, deep scour at the mouth is less developed than after
construction, with the shallower nearshore depths merging at the channel mouth.
Therefore, the nearshore is also a focus area for 2015/2016.
• Beach Nourishment at North Padre Island Seawall
The shoreline position fronting the seawall has steadily receded since placement during
the combined nourishment conducted over the primary nourishment conducted during the
winter of 2011/2012 and supplementary placement in 2012/2013. The rate of recession
2
EXHIBIT"A"
Page 2 of 11
has moderated and is comparable to that observed after the initial placement during 2005.
At the present rate of change the shoreline at the south end of the seawall is predicted to
approach the baseline 2011 position within 2 years in the absence of the influence of
tropical storms or other extreme events. Post-construction monitoring between 2005 and
2011 determined that the recent rate of shoreline change along the shoreline stretching
from the south jetty to 1-mile south of Bob Hall Pier is on the order of -2.43 ft/yr
(including influence of nourishment at seawall). While the average rate of change
calculated for the direct nourishment region along the seawall was on the order of-9.72
ft/yr. The rate of change is often accelerated immediately post-nourishment. As of
Apr 2015, approximately 2-years post-nourishment, the shoreline at the south end of the
seawall had receded on the order of 50 to 80 ft or at an average rate of 30 ft/yr. Within
the placement area (Holiday Inn to Whitecap Blvd) the shoreline was either at or in
advance (seaward) of the 2011 position by up to 50 ft (south end) during Apr 2015. Of
interest was that the shoreline north of the placement area was landward of the 2011
position by up to 40 ft, likely related to a combination of management practices and
strong winter forcing that continued into the late spring. The moderation of such change
over the summer months will be a focus of the monitoring program during the summer of
2015.
• Shoreline Change at North Packery
The shoreline north of Packery Channel between the north jetty and Newport Pass
advanced on the order of 50 to 70 ft between Nov 2013 and Feb 2014 and approximately
00 ft between Sep 2014 and Apr 2015. Prior to these two bursts of advance over two
successive winter periods the shoreline had been relatively stable with moderate
incremental advance observed since 2009. Additional analysis will investigate related
changes in the nearshore morphology and the potential contribution of associated
nearshore advance to shoaling at the mouth and in the entrance channel. The recent
changes are attributed to a combination of maintenance practices and a greater influence
of strong winter forcing over the winter of 2014/2015 on sediment transport.
• Continuation of real-time Water Current Monitoring
Water current has been monitored in the GIWW and in Packery Channel since 2006. This
data provides information on potential changes in hydrodynamics as changes in channel
morphology occur due to shoaling and scour. Additional changes in the channel system
are proposed by local developers including the connection of the Laguna Madre to
Packery via Lake Padre which may result in unanticipated changes to flow. Therefore the
monitoring stations provide a baseline as well as provide for analysis of change in flow.
The funding for these stations was originally provided by the USACE and intermittently
as recently as 2014. No funding is presently available to maintain these stations.
Although outside funding will continue to be sought, funding for this component is
requested for 2015/16 to maintain continuity and avoid interruption of data collection.
Background
• Monitoring began in August 2003, prior to construction (originally funded by Galveston
District, USACE and the Coastal Hydraulics Laboratory, Coastal Inlets Research
Program).
• Inlet opened during Hurricane Emily (July 2005), one year prior to completion of
construction (October 2006).

EXHIBIT"A"
Page 3 of 11
• Sponsorship of monitoring transferred to the City of Corpus Christi (2008 to present).
• Limited dredge in Deposition Basin at ramp to facilitate boat entry(Jan 2010).
• Notice to Mariners issued regarding elevation of Entrance Shoal (Sep 2010).
• Dredge (#1) of channel from Deposition Basin to Entrance Channel to within 550 ft of
the channel mouth (completed March 2012). Total pay volume was 190,757 cu yd
(HDR). Completion of dredge was deferred to Winter 2012/2013.
• Dredge (#2) of Inner Entrance Channel and Entrance Channel completed to within 550 ft
of channel mouth (completed March 2013). Total volume was 48,757 cu yd.
Remaining 550 ft of Entrance Channel shoal was not removed.
• Notice to Mariners issued regarding elevation of Entrance Channel Shoal (Jul 2014).
• Greatest period of scour of persistent entrance shoaling to date during Apr 2015 (net loss
of 12,000 cu/yd from Entrance Channel).
Ongoing Contribution of Program
• Program supports pro-active system management by the City of Corpus Christi.
• Analysis has supported decision to defer dredging, originally predicted at an interval of
every 2-3 years,to 5 years from channel completion.
• Analysis has identified need(shoaling) for placement of aids to navigation.
• Seasonal data identified need for initiation of Notice to Mariners during September 2010
and July 2014 due to shoaling and potential of limited navigation at the channel mouth.
• Data and analysis applied to request FEMA reimbursement after Hurricane Ike.
• Data and analysis document measured condition (as opposed visual interpretation often
reported by community).
• Data and analysis applied to assess post-dredge 2011/2012 condition for recommendation
of Dredge#2 to complete to specifications.
• Monitoring of nourishment fronting seawall for vehicular access concerns and bollard
placement.
• Analysis to support alternative dredge/nourishment funding sources such as CEPRA
grants initiating in 2015.
Continuation of Monitoring and Analysis
• Monitor persistence of bypass bar and increased nearshore shoaling at mouth for potential
ebb shoal formation.
• Quantify post-dredge channel shoaling and scour and determine early trends.
• Quantify change in post-nourishment beach width and volume along seawall.
• Initiate warnings should the potential for depth limited seasonal monitoring of shoaling
will allow adequate warning of navigation limitation and support dredge implementation
or placement of navigation aids.
• Track Changes through historic beach profile and shoreline surveys for planning beach
nourishment and/or redirection of vehicular access.
• Track changes in Inland channel bank expansion that could impact protected habitat,
residential property, and Nueces County Park boundaries.
• Prepared to mobilize rapidly to monitor post-storm conditions as needed.
Seasonal Monitoring and Long-term Channel Management
4
EXHIBIT"A"
Page 4 of 11
The key to successful management of an inlet system is knowledge of the processes that force
sand into and out of the system; and to identify developing and changing trends in sediment
transport, particularly after major changes such as channel dredging or in the case of storm
damage. Seasonal monitoring at Packery Channel provides for the tracking of changes over
rapid short period and historic intervals which allows both 1) identification of trends in sediment
transport and 2) deviation from established trends that could indicate a change in system
dynamic and need for management action. The monitoring program has documented both a
seasonal and event driven component to sediment transport in this system with shoaling most
prevalent during the spring and throughout the summer as well as during storms. Future
monitoring will determine if the change in channel depth due to dredging will alter the
magnitude and rate of such seasonal change.
Monitoring Program Tasks
The 2015/2016 amendment to the existing contract (Project# E14051) for the Packery Channel
Monitoring Program consists of five tasks. The five Tasks are outlined as a guide following the
successful program implemented in 2008. The goal of the 2015/16 year is to measure and
document the continued changes in post-dredge status of channel morphology and post-
nourishment status of the adjacent beach. The program will continue to assist the City in the
anticipation of future dredge events and document the annual pre-storm beach width and volume
for FEMA reimbursement should the area sustain damage during seasonal hurricanes. The
monitoring will directly support the City of Corpus Christi in the coordination of potential
CEPRA grant funded support of dredging and subsequent nourishment of the beach fronting the
North Padre Island Seawall.
Unallocated Funds
The opportunity to apply funds previously unallocated may be exercised by the City of Corpus
Christi with the potential to reduce the budget commitment for Amendment 11. The actual
amount available will be assessed at the time of amendment authorization at the end of the
summer storm season.
Task Implementation
Tasks 1-5 may be conducted simultaneously or independently and in the order that best supports
the monitoring program goals.
Task 1. Project Management
1-1. Project Management
Description
Project management includes historic analysis, reporting, survey organization and scheduling as
well as presentations and generation of materials in support of the management of the inlet and
associated beach and wetland by the City of Corpus Christi. Additional support includes

1-2. Aerial Photography
Description: Acquisition of an annual set of rectified aerial photographs of the Packery Channel
region including the entire channel from the GIWW to the Gulf of Mexico (GOM); including
North Padre and Mustang Islands from the south end of the seawall to Newport Pass.
Photographs are applied in ArcGIS environment for comparative analysis of change relative to
key features and as a reference for overlay of data and terrain models. Bids received during 2015
indicate that the estimated cost of aerial photography is comparable to the 2014 effort.
Purpose: For interpretation of large-scale changes in vegetation, dune line, and inter-tidal
regions adjacent to the inland segment of the channel as well as along Padre and Mustang
Islands. Aerial imagery is particularly important to document adjacent regions that are outside of
the topographic survey area. In addition, the aerial imagery is applied as a backdrop to channel
and beach elevation data. The aerial images are critical for application to the development of
visuals and explanation aids to City staff, residents and laypersons.
Schedule:
(1) Annual set of imagery conducted Sep/Oct 2015 (pending weather conditions).
(2) QA/QC of imagery and integration into GIS project
Cost:
Aerial Imagery: $12,000 (Vendor acquired)
Salary/Wages/Supplies/Travel/F&A: $9,634
Estimated Cost Task 1-2: $ 21,582
Task 2. Measurement of Morphologic change in Packery Channel and along Mustang and
Padre Island.
2-1. Beach Profile Surveys
Description:
Beach profile surveys provide detailed information describing changes in elevation and
morphology at 18 specified locations along the beach stretching from the Nueces Kleberg
County Line to north of Fish Pass at Mustang Island State Park. There are historic data for these
locations since 1995. The beach profile survey has been conducted annually during the peak
summer period to allow for analysis of change that reflects the same forcing agents active over
the summer season. Elevation measurements are collected along transects that initiate landward
of the dune or other landward limiting feature (seawall or pavement) and extend offshore up to
one mile into the Gulf of Mexico. The surveys capture the region of active sediment transport
and therefore extend offshore to a depth, referred to as the depth of the closure, beyond which
limited movement of the sediment occurs.
A denser transect grid is applied along the beach fronting the North Padre Island (NPI) Seawall
in an effort to quantify volumetric change and document changes in beach profile with greater
detail. This information is applied to monitor change before during and after nourishment of the
beach fronting the seawall and along the area south near Whitecap Blvd.
6
EXHIBIT"A"
Page 6 of 11
Purpose: To document changes in features such as the dune toe (seaward limit of dunes) berm
crest (most landward point of active sediment transport on the beach), and sand bars. The data
are applied to determine regions of erosion and to calculate volumetric change along historically
surveyed areas of the beach. This data set is critical to the calculation of sand volume which is
required for sand placement and documentation for FEMA funding. Data is also applied to
verify shoreline position data and to determine the maximum region of sheltering along the
beach (Zone of Influence) that is provided by the jetties. An additional set of beach profile
transects was added to better describe the beach fronting the NPI Seawall to facilitate more
accurate monitoring of changes in the recent beach nourishment. This focused survey along the
nourishment area includes profiles at 400-ft to 1100-ft spacing to accommodate more accurate
beach volume calculations for FEMA application.
Schedule:
(1)One annual survey conducted during peak summer condition(Sep/Oct 2015).
(3) Three intensive surveys of beach nourishment area fronting the NPI seawall (Sep/Oct 2015,
Feb/Mar 2016 and Jun 2016).
Cost:
Annual Survey: $ 19,900.00
NPI Seawall Surveys: $17,925.00
Salary/Wages/Benefits/Supplies/Travel/F&A: $11,927
Estimated Cost Task 2-1: $49,752
2-2. Shoreline Position Surveys
Description: Elevation data are collected by RTK GPS across the beach from close to the dune
toe to the water line along a zigzag path in order to cover the entire beach face. The beach is
surveyed from south of the Nueces Kleberg County Line to north of Fish Pass at Mustang Island
State Park.
Purpose: Shoreline position surveys are an efficient and low-cost way to measure changes in the
elevation of the dry beach berm over the broad study area. Within days, a large section of the
beach can be measured to determine changes in shoreline position from which regions of beach
erosion and accretion can be determined and potential "hot spots" can be identified. Monitoring
the seasonal position of the shoreline assists in management of beach vehicular access south of
the inlet and addresses persistent regions of shoreline recession and resulting narrowing of beach
that have been identified fronting the North Padre Island Seawall and Whitecap Blvd. This data
is instrumental to the management of bollard placement along the North Padre Island Seawall.
Schedule:
(3) Three Seasonal Surveys. Tentative survey schedule: Sep/Oct 2015, Jan/Feb 2016 and Jun
2016.
Cost:
Survey: $11,700
Salary/Wages/Benefits/Supplies/Travel/F&A: $ 8,263
Estimated Cost Task 2-2: $19,963
2-3. Surveys of Channel and Nearshore Depth and Morphology (Features of seafloor and
bottom of channel)
7
EXHIBIT"A"
Page 7 of 11
Description: These bathymetric surveys combine single-beam (nearshore/offshore) and multi-
beam (channel) sonar coverage to provide high-resolution data sets that describe the morphology
(shoals, scour and sandbars) on the channel bottom and seafloor. The analysis of seasonal data
sets is applied to interpret pathways of sediment transport and to anticipate development of
features such as bypass bars, channel shoals and ebb shoaling.
Purpose: Data is applied to define morphologic features such as shoals (areas of deposition) and
scour (areas of erosion) in the channel, nearshore and around structures. This data is applied to
interpret pathways of sediment transport and to calculate volumetric change for application to the
estimation of the sand volume available for dredging. The data are applied to interpret trends in
sediment transport as well as to calculate volumetric change indicating sand loss or gain, to
prepare for nourishment projects, and to identify potential regions of shoaling which could limit
navigation. A primary application of this data is to identify trends in shoaling which provides
guidance in future dredge planning and the identification of navigation hazards.
Schedule:
(3) Three Seasonal Surveys. Tentative survey schedule: Sep/Oct 2015, Jan/Feb 2016 and
Jun 2016 (abbreviated-Basin to Gulf only). Additional surveys may be required if data indicate
that shoaling is rapidly increasing and depth-limited navigation is imminent.
Cost:
Survey: $ 79,300
Salary/Wages/Benefits/Supplies/Travel/F&A: $ 17,993
Estimated Cost Task 2-3: $ 97,293
2-4. Inland Channel Segment and Mollie Beattie Coastal Habitat Community(MBCHC)
Description: The inland channel segment bordering MBCHC continues to modify as the region
adjusts to changes in water flow in the channel and over the wetland. These changes are best
captured seasonally through a network of cross-sections that document changes in wetland
extent, channel boundaries and shoreline change. Elevation is measured along transects or
survey lines, that are roughly perpendicular to channel orientation. The surveys start at the
location of the mean higher high water (MHHW) shoreline position located along the western
residential shore and then extend across the channel to the location of MHHW shoreline position
or until a limiting feature (such as coverage of a raised placement area) is defined. The position
of the MHHW shoreline position is measured along the residential side of the channel extending
from the HWY 361 Bridge to the Relief Channel west of the channel dog leg. The MHHW
position is not as well defined along the MBCHC due to extended sections of submerged area,
therefore a MHHW position survey is not conducted on the east side of the channel.
Purpose: These surveys define morphologic change in the inland segment of the channel that
borders the MBCHC as well as changes in the elevation across sections of the wetland. The
purpose is to evaluate the response of the channel and wetland to the opening of the inlet and
assess the approach to an equilibrium status. Analysis of this data set provides quantification of
change in the primary (-5 ft) and upper bank (MSL) width along the channel bordering the
MBCHC. In addition, the MHHW position of the west side of the inland channel segment
(residential) is compared to historic survey data surveys to determine historic change in position.

(2) Survey Sets (Transects and MHHW). Tentative survey schedule: Sep/Oct 2014,
Jan/Feb 2015. Additional surveys may be required if data indicate that the rate of change has
increased during the study period.
Cost:
Survey: $ 18,800
Salary/Wages/Benefits/Supplies/Travel/F&A: $ 11,995
Estimated Cost Task 2-4: $ 30,795
2-5. Event/Transitional Survey and/or Dredge Support
Description: In a continued effort to respond to City of Corpus Christi budgetary constraints,
the monitoring program continues at a modified schedule to include (2) seasonal surveys
(Sept/Oct 2015 and Jan/Feb 2016) and (1) transitional reduced-cost survey (June 2016). To
accommodate monitoring concerns beyond these seasonal surveys the Event Task provides for
event surveys or other survey requirements as needed. Such support outside of seasonal surveys
could include but is not limited to dredge support, engineering support, environmental
assessment (wetland, endangered species, modeling hydrodynamics), and sand placement
activities outside the seasonal survey scope. The primary purpose of the event surveys is to
facilitate timely pre- or post- storm surveys. Surveys may be needed beyond the seasonal
designation, such as after storms, and to assist with the investigation of sensitive environmental
habitat or anthropogenic influences on the coastal environment that are identified during the
course of the three seasonal surveys. The cost is based upon the following survey suite but may
be utilized as needed in support of management concerns on an as needed basis.
An additional line item is the maintenance of the water current monitoring stations in the GIWW
and Packery Channel. Monitoring changes in current flow provides data for future studies of
hydrodynamic change potentially associated with the addition of channels in the Lake Padre
region of the study area. Monitoring includes the public online data access to real time
measurement of water current velocity (http://lighthouse.tamucc.edu/gc/138 and
http://lighthouse.tamucc.edu/qc/150). These stations were previously funded by the USACE
(2006-2014) but no funding has been identified or secured for 2015/16. Funding options will
continue to be explored to fund these stations in the future.
The Task 2-5 cost is based upon the following Monitoring suite for budget development but may
be utilized as needed in support of City of Corpus Christi Packery Channel management
concerns on an as needed basis. Funds not allocated at the end of the contract period may be
conserved for future applications.
a. Shoreline position survey(1)Task 2-2.
b. Abbreviated Bathymetry survey(1)
c. Full bathymetric channel and nearshore survey (1) as described in Task 2-3.
d. Beach profile survey(1)Task 2-1.
e. Current monitoring in Packery Channel and GI W W
