General Recommendations:

Miscellaneous codes include general concerns that are not activity-specific and that apply to sensitive areas and habitats along the coast. These include, but are not limited to, the following: Coastal wetlands; Tidal sand and mud flats; Submerged aquatic vegetation; hard substrate reefs; Cultural resources; Bird rookeries; Private oyster leases; Dredge material placement areas; Endangered species habitat; Designated sand sources; and Designated-use areas.

Dredging may not be allowed and other construction activities should be located at safe distances from sensitive areas. Specific setback distances depend on the type of sensitive areas present. Special methods may need to be incorporated to reduce turbidity and sedimentation impacts to sensitive areas from construction activities. A survey to locate any existing sensitive areas may be required before activity commences. In addition, plans for development and routes and methods of structure installation or construction must be included on applications for U.S. Army Corps of Engineers permits and Texas General Land Office plat maps for all state-owned submerged lands.

All activities should be coordinated with the commenting agencies and should use Best Management Practices to avoid unnecessary impacts to sensitive areas. The following mitigation sequence may be applied during the evaluation of potential adverse impacts of a project: (1) avoidance of adverse impacts; (2) minimization of adverse impacts; and (3) compensation for unavoidable adverse impacts.

Definitions and Explanations

  • MA - No special recommendations relating to sensitive areas, other than cultural resources.
    No specific concerns have been identified at this time.

  • MB – Avoid impacts to hard substrate reefs.
    This tract contains hard substrate reefs which include rock outcrops, coral reefs, serpulid worm reefs (living or dead) and relic reef structures in intertidal or subtidal areas. Activities may be permissible if best management practices are used to avoid adverse impacts to these sensitive habitats.

  • MC – Avoid impacts to artificial reefs.
    This tract contains artificial reefs; however, activities may be permissible if best management practices are used to avoid adverse impacts to these sensitive habitats.

  • MD – Avoid impacts to tidal sand and mud flats.
    This tract contains tidal sand and mudflats; however, activities may be permissible if best management practices are used to avoid adverse impacts to these sensitive habitats.

  • ME – Avoid impacts to coastal wetlands.
    Coastal wetlands exist within this tract; however, activities may be permissible if best management practices are used to avoid adverse impacts to these sensitive habitats. A survey may be required to locate existing wetlands.

  • MG – Avoid impacts to submerged aquatic vegetation.
    Submerged aquatic vegetation, such as seagrass, has been documented on this tract; however, activities may be permissible if best management practices are used to avoid adverse impacts to these sensitive habitats. A survey may be required to locate existing submerged aquatic vegetation.

  • MI – Avoid impacts to bird rookeries.
    Bird rookeries exist within this tract; however, activities may be permissible if best management practices are used to avoid adverse impacts to these sensitive habitats.

  • MJ – Cultural resources may be present.
    These tracts lack sufficient data regarding the presence of submerged cultural resources. An archeological remote-sensing survey, issued under a Texas Antiquities Permit, may be required for proposed work that introduces bottom disturbing activities such as dredging and/or creation of sediment placement areas. Consult with the Texas Historical Commission for more information.

  • MK – Avoid impacts to cultural resources.
    State Antiquities Landmarks or other cultural resources protected by state law are known to be or may be located on this tract and should not be disturbed. An archeological remote-sensing survey, issued under a Texas Antiquities Permit, may be required prior to commencement of activities. Consult with the Texas Historical Commission for more information.

  • ML – This tract contains private oyster leases.
    Private oyster leases have been documented on this tract. Consult with the Texas Parks and Wildlife Department for more information.

  • MM – Avoid impacts to public oysters characterized as reefs, beds, patches, or scattered.
    Oysters (reefs, beds, patches, or scattered) exist on this tract; however, activities may be permissible if best management practices are used to avoid adverse impacts to these sensitive habitats. A survey may be required to locate existing oyster cover.

  • MN – Work on this tract is subject to state threatened or endangered species regulations.
    Activities conducted on this tract would require consultation with the Texas Parks and Wildlife Department. Laws and regulations pertaining to endangered or threatened species are contained in Chapters 67 and 68 of the Texas Parks and Wildlife Code and Sections 65.171 - 65.176 of Title 31 of the Texas Administrative Code.

  • MO – Work on this tract is subject to review under the Endangered Species Act.
    Activities conducted on this tract would require consultation with the corresponding agency. The U.S. Fish and Wildlife Service administers the Endangered Species Act for freshwater and land-based species, while the National Marine Fisheries Service is responsible for marine species.

  • MP – This tract contains designated use areas.
    This tract contains designated use areas such as coastal protected areas, navigation districts, patented areas, and other designated use areas, which may be subject to special recommendations. Federal, state and local government entities should be consulted regarding restrictions or special use permits.

  • MR– This tract contains restoration areas.
    This tract contains restoration areas; activities should not be undertaken which may adversely impact restoration features or the intended recovery of the ecosystem or which may undermine the management goals established for that area.

  • MS – This tract contains mitigation sites.
    This tract contains sites established for the purpose of providing compensatory mitigation; however, activities may be permissible if best management practices are used to avoid adversely impacting mitigation features.

  • MV – This tract contains identified sand sources.
    This tract contains identified sand sources; however, activities may be permissible if conflicts with other uses of this area are avoided.

  • MX – This tract contains dredge material placement areas.
    This tract contains dredge material placement areas; however, activities may be permissible if conflicts with other uses of this area are avoided.
