Coastal Coordination Advisory Committee



On January 10, 1997, the State of Texas received federal approval of the Coastal Management Program (CMP) (62 Federal Register pp. 1439 - 1440). Under federal law, federal agency activities and actions affecting the Texas coastal zone must be consistent with the CMP goals and policies identified in 31 TAC Chapter 501. Requests for federal consistency review were deemed administratively complete for the following project(s) during the period of December 18, 2020 to January 8, 2021.  As required by federal law, the public is given an opportunity to comment on the consistency of proposed activities in the coastal zone undertaken or authorized by federal agencies.  Pursuant to 31 TAC §§506.25, 506.32, and 506.41, the public comment period extends 30 days from the date published on the Texas General Land Office web site. The notice was published on the web site on Friday, January 15, 2021.  The public comment period for this project will close at 5:00 p.m. on Sunday, February 14, 2021.

FEDERAL AGENCY ACTIONS:

Applicant: Port of Corpus Christi Authority

Location: The project site is located in Corpus Christi Bay at Indian Point, Portland,

Nueces and San Patricio Counties, Texas.

Latitude & Longitude (NAD 83): 27.85109, -97.35711

Project Description: The applicant proposes the placement of a maximum of 5,000 cubic yards (cy) of sand along approximately 3 acres of the Indian Point shoreline to stabilize the soil, help absorb low-energy waves, and increase intertidal habitat conditions by establishing a stable slope for the shoreline. The sand fill would be placed along the shoreline below the High Tide Line (HTL) within the unvegetated bay bottom. Fill would not be placed within any existing seagrass areas. Nearshore segmented breakwaters placed in approximately 2 acres of bay bottom would further absorb wave energy offshore and create a low-energy environment in the lee area; they may be constructed of approx. 10,000 cy of material or units composed of concrete, rock, steel, mesh, geotextile, geogrid, bedding stone, piles, chains, anchors, floating platforms, oyster shell, or similar placed within unvegetated bay bottom below the HTL. Oyster reefs would be constructed to provide new marine habitat; they would be composed of approximately 2,000 cy of shell hash, shell bags, live oysters, or similarly placed material within unvegetated bay bottom below the HTL in an approximate 1.5-acre area. 

The offshore breakwaters would be constructed using heavy construction equipment such as barge-mounted excavators, marsh excavators, or similar. The rock would be selectively placed to meet the designed breakwater parameters, elevations, and slopes. The beach fill would likely be constructed using land-based earthwork equipment such as loaders, mini excavators, and similar. The oyster reefs may be installed by hand and/or with heavy equipment such as an excavator. Construction material may be stockpiled on land away from any sensitive habitats and/or on barges anchored within the work area limits. Silt curtains or approved equal Best Management Practices (BMPs) would be placed adjacent to existing seagrasses. The water depths are shallow where the silt curtains would be placed, but stakes may be used to secure the curtain if needed. Stakes would be either installed by hand or pushed into the bottom using an excavator. Operations requiring sound mitigation such as impact driving are not proposed as part of this project. As the breakwaters are constructed, wave energy in the lee area (i.e., where the silt curtains would be located) would reduce. It is anticipated that the silt curtains would be stable, and the contractor would be required to monitor and maintain the curtains throughout construction to ensure their placement remains stable, and they function as needed.

Type of Application: U.S. Army Corps of Engineers permit application # SWG-2020-00839. This application will be reviewed pursuant to Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the Clean Water Act. The consistency review for this project may be conducted by the Texas Commission on Environmental Quality as part of its certification under §401 of the Clean Water Act.

CMP Project No: 21-1161-F1
