'Williams The Conrad Blucher Institute for Surveying and Science Texas A&M University-Corpus Christi 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. This proposal provides for the application of unobligated funds from Amendment #7 and #8 for the purpose of expediting the channel bathymetric survey to investigation the region of shoaling that peaked during July 2014. This effort represents only a subset of the tasks that compose the annual monitoring program. Monitoring Program Tasks This proposal describes the Tasks that will be conducted under Amendment 9. This represents only a subset of the overall 2014/2015 monitoring year. The remaining Tasks will be authorized in Amendment 10 which is anticipated during October 2014. In addition Tasks 2-3 and 2-4 are only partially provided for by Amendment 9. All components of Tasks 2-1 and 2-2 will be completed under Amendment 9. All tasks are shown for continuity but a budget is provided only for the tasks to be directly covered under 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 EXHIBIT"A" Page 1 of 5 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. Differed to Amendment 10 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. Schedule: (1) Annual set of imagery conducted Sep/Oct 2014 (pending weather conditions). Differed to Amendment 10 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. 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 EXHIBIT"A" Page 2 of 5 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: $20,000 NPI Seawall Surveys: $11,950 Salary/Wages/Benefits/Supplies/Travel/FA: $16,960 Estimated Cost Task 2-1: $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 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: $7,800 Salary/Wages/Benefits/Supplies/Travel/FA: $8,502 Estimated Cost Task 2-2: $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 EXHIBIT"A" Page 3 of 5 • 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: One (1) Seasonal surveys will be conducted during Sep/Oct 2014. Two (2) additional surveys are proposed for the 2014/2015 monitoring year. Additional surveys may be required if data indicate that depth-limited navigation is imminent. Cost: Survey: $28,700 (Differed to Amendment#10 S50,600) Salary/Wages/Benefits/Supplies/Travel/FA: $1,936.45 (Differed to Amendment #10 534,176.55) Estimated Cost Task 2-3: $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 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: (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: $9,400 Salary/Wages/Benefits/Supplies/Travel/FA: $0.00 (Differed to Amendment 10 ($14,895)) Estimated Cost Task 2-4: $9,400 EXHIBIT"A" Page 4 of 5 • 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 2012 and Jan/Feb 2013) and (1) transitional reduced-cost survey (June 2013). 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). £ Abbreviated Entrance Channel Shoal Survey (1) planned for Aug/Sep 2014 to monitor changes in the Entrance Channel shoal that had expanded to potentially limit navigation (Identified during the July 2014 survey). 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. Differed to Amendment 10 Deliverables: ASCII data sets (x,y,z)NAVD88 State Plane south Zone FIPS 4205 Email status report (monthly or as updates are available) Status Reports (post-survey reports) Note: all surveys may be rescheduled based upon study findings or weather and sea conditions. Additional surveys may be recommended upon seasonal findings or evidence of change based upon observations in the field.
