I. SERVICES TO BE PERFORMED
TAMU-CC hereby agrees to perform all consulting services necessary to monitor, perform,
complete, and report the results of a comprehensive study of morphology and changes and
current velocity at Packery Channel.
IL SCOPE OF SERVICES
TAMU-CC's services will be those necessary to provide the monitoring required to deliver an
annual written report and presentation of the observations and results of the monitoring program
that takes place during the term of this contract.
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.
TAMU-CC will complete the tasks in Section II as set forth in the research proposal attached as
Exhibit "A".
A. TASKS
Specific tasks to be undertaken are set out as follows:
Task 1. Project Management and Aerial Photography
1-1. Project Management
Project management includes historic analysis, reporting, survey organization and scheduling as
well as presentations and generation of materials requested by the City of Corpus Christi.
Additional support includes coordination with surveyors, engineers and other environmental
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 2014 show that the cost
of aerial photography is comparable to the 2013 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 2014 (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 2014).
(2) Intensive surveys of beach nourishment area fronting the North Padre Island
seawall (Sept/Oct 2014 and Feb/March 2015)
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: (2) Surveys. Tentative survey schedule: Sep/Oct 2014, Jan/Feb 2015.
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.

CHANNEL MONITORING 2014-2015.DOCX Page 2 of 6
,
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 2014, Jan/Feb 2015 and June 2015.
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: Jan/Feb 2015,
Second Survey conducted under Amendment 9. 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 2014 and Jan/Feb 2015) and (1) transitional survey (June 2015). 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:
a. Shoreline position survey (1) Task 2-2.
b. Abbreviated MBCHC survey (1) Task 2-2 OR TBA survey up to 5 days.
c. Bathymetric channel and nearshore survey (1) as described in Task 2-3.
d. Beach profile survey (1) Task 2-1.
e. Baseline survey of existing bathymetry of the Lake Padre region and canals of Padre
Isles
(does not include modeling or analysis).
Purpose: To define morphology immediately before or after a storm event or related to sensitive

Packery Channel Monitoring Program
Proposed Amendment #10 (2014/15)
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 2014/2015
Monitoring and analysis will continue to focus on both the channel mouth and nourished region
along the North Padre Island Seawall during 2014/2015. The following are specific areas of
concern over the next monitoring year.
• Entrance Channel Shoal and Navigation
Monitor changes in area of localized shoaling along the south jetty that was measured
during July 2014 and stimulated a Notice to Mariners to be recommended. Future
abbreviated surveys will be performed to track changes and provide public updates on
channel navigability at the peak of summer season.
• 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 a bypass bar have repeatedly developed in
response to seasonal forcing and events such as Hurricane Ike. In addition, deep scour at
the mouth is no longer well-developed, with the shallower nearshore depths merging at the
channel mouth. Therefore, the nearshore is also a focus area for 2014/2015.
• Beach Nourishment at North Padre Island Seawall
The shoreline position fronting the seawall has steadily receded since placement during the
primary nourishment conducted during the winter of 2011/2012 and supplementary
placement in 2012/2013. The rate of recession is comparable to that observed after the
initial placement during 2005. At the present rate of change the shoreline at the south end
EXHIBIT"A"
2 Page 2 of 10
of the seawall is predicted to approach the baseline 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. As of Feb 2014, the shoreline at the south end of the seawall had receded on
the order of 50 to 80 ft, after one year post-nourishment. The rate of change moderated to
on the order of 20 ft to the north and south of the end of the seawall at Whitecap Blvd.
• 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. Prior to this winter
period the shoreline had been relatively stable without significant advance 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.
• Documentation of Baseline Bathymetry of Lake Padre and Padre Isles Canals
A baseline survey of the existing bathymetry of the Lake Padre and Padre Isles Canals will
be conducted. A channel connecting the Padre Isles canal system to Lake Padre has been
proposed by developers. This would provide a new connection providing for water
exchange between the Laguna Madre and Gulf of Mexico via Packery Channel. No studies
of potential change in hydrodynamics or subsequent changes in bathymetry have been
conducted by the developers to date. This baseline survey will document the existing
bathymetry prior to changes in hydrodynamics of the system. An additional shoreline
survey may be recommended to document the position of MHHW.
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).
• Sponsorship 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).
Ongoing Contribution of Program
• Program supports pro-active system management by the City of Corpus Christi.
EXHIBIT"A"
3 Page 3 of 10
•
• 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.
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.
• Seasonal monitoring of shoaling will allow adequate warning of navigation limitation and
support dredge implementation or placement of navigation aids.
• Beach profile and shoreline surveys continue to track changes in beach width for planning
beach nourishment and/or restriction of vehicular access.
• Inland channel surveys track changes in bank expansion that could impact protected
habitat, residential property, and Nueces County Park boundaries.
• Proposed changes to adjacent system: Define baseline conditions in Lake Padre and canal
system prior to channel changes at Park Road 22.
Seasonal Monitoring and Long-term Channel Management
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 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 tracking of changes which allows both 1) identification of trends in
sediment transport and 2) deviation from those trends that could indicate a change in system
dynamic and need for management action. The monitoring program has documented both a
seasonality and event driven component to sediment transport in this system with shoaling most
prevalent during the summer and after 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
This proposal describes the 2014/2015 amendment (Amendment 10) to the existing contract for
the Packery Channel Monitoring Program. Five Tasks are outlined as a guide following the
EXHIBIT"A"
4 Page 4 of 10
•
successful program implemented in 2008. The goal of the 2014/15 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.
Amendment 9 (September 2014)
Amendment 9 provided for immediate authorization of surveys necessary to determine changes in
the shoal that peaked with potential to limit navigation during July 2014. Unobligated funds from
Amendment 7 and 8 were applied to facilitate the survey in a timely manner. Therefore the annual
survey cost per task shown has been reduced by that funded by Amendment 9.
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
coordination with surveyors, engineers and other environmental professionals to assist the City of
Corpus Christi with related projects including potential dredge operations and/or FEMA
reimbursement for storm damage.
Cost:
Salary/Wages/Benefits/Supplies/Travel/FA: $53,988
Estimated Cost Task 1-1: $53,988
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 2014 indicate that the
cost of aerial photography is comparable to the 2013 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. In addition, the aerials are critical for application to the development of visuals and
explanation aids to City staff, residents and laypersons.

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.
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 North Padre Island 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) Annual survey conducted during peak summer condition (Sep/Oct 2014).
(2) Intensive surveys of beach nourishment area fronting the North Padre Island seawall (Sept/Oct
2014 and Feb/Mar 2015).
Cost:
Annual Survey: $ 0.00 (Amendment#9 funded $20,000)
NPI Seawall Surveys: $ 0.00 (Amendment #9 funded $11,950)
Salary/Wages/Benefits/Supplies/Travel/FA: $0.00 (Amendment #9 funded $16,960)
Estimated Cost Task 2-1: $0.00 (Amendment#9 Total: $48,910)
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
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
EXHIBIT"A"
6 Page 6 of 10
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. This data is instrumental to the management of the future bollard placement
along the North Padre Island Seawall.
Schedule:
(2) Seasonal Surveys. Tentative survey schedule: Sep/Oct 2014 and Jan/Feb 2015.
Cost:
Survey: $0.00 (Amendment#9 funded $7,800)
Salary/Wages/Benefits/Supplies/Travel/FA: $0.00 (Amendment#9 funded $8,502)
Estimated Cost Task 2-2: $0.00 (Amendment #9 Total: $16,302)
2-3. Surveys of Channel and Nearshore Depth and Morphology (Features of seafloor and
bottom of channel)
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
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 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 identify navigation hazards.
Schedule:
(3) Seasonal Surveys. Tentative survey schedule: Sep/Oct 2014, Jan/Feb 2015 and June 2015
(abbreviated-Basin to Gulf only). Additional surveys may be required if data indicate that depth-
limited navigation is imminent.
Cost:
Survey: $50,600 (Amendment#9 funded $28,700)
Salary/Wages/Benefits/Supplies/Travel/FA: $34,176.55 (Amendment#9 funded $1,936.45)
Estimated Cost Task 2-3: $84,776.55 (Amendment#9 Total: $30,636.45)
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
EXHIBIT"A"
7 Page 7 of 10
•
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.
Schedule:
(1 of 2) Survey Set (Transects and MHHW). Tentative survey schedule: Jan/Feb 2015. Second
survey conducted under Amendment 9. Additional surveys may be required if data indicate that
the rate of change has increased during the study period.
Cost:
Survey: $9,400 (Amendment#9 funded $9,400)
Salary/Wages/Benefits/Supplies/Travel/FA: $14,895 (Amendment#9 funded $ 0.00)
Estimated Cost Task 2-4: $24,295 (Amendment #9 Total: $9,400)
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
2014 and Jan/Feb 2015) and (1) transitional reduced-cost survey (June 2015). 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:
a. Shoreline position survey (1) Task 2-2.
b. Abbreviated MBCHC survey (1) Task 2-2 OR TBA survey up to 5 days.
c. Bathymetric channel and nearshore survey (1) as described in Task 2-3.
d. Beach profile survey (1) Task 2-1.
e. Baseline survey of existing bathymetry of the Lake Padre region and canals of Padre Isles
(does not include modeling or analysis).
Purpose: To define changes in morphology, wetland boundaries, volume, and bathymetry of
associated waterways related to issues outside of the umbrella of the seasonal surveys.
Schedule: Post-storm and as needed relative to management concerns during 2014/2015. Other
tasks as directed by City staff.
