Proposed Features on the Upper Texas Coast
Orange, Jefferson, Chambers, Harris, Galveston, and Brazoria counties

As shown on the map below, the Gulf of Mexico coastline and the Galveston Bay are two different vulnerable areas. Each of these areas requires different and uniquely tailored measures of protection. The proposed projects for both the bay and the gulf are listed below:


The Gulf Side

  • Bolivar Roads Gate System
    This surge mitigation gate would stretch across the entrance to the Houston Ship Channel, between Bolivar Peninsula and Galveston Island. The proposed gate has been updated to provide a more efficient way to prevent storm surge while reducing the overall cost of the structure.
  • Galveston Seawall
    The current Galveston Seawall does not currently provide robust protection from storm surge. The existing 10-mile Seawall on Galveston Island will be improved to complete the continuous line of defense against the Gulf surge, along with an increase in height in some regions.

    To better understand the Bolivar Roads Gate System and Seawall improvement features, see the StoryMap titled: Bolivar Roads Gate System.
  • Beach and Dune Improvements
    To reduce storm surge from entering the Bay system, the Upper Coast Plan includes 43 miles of beach and dune improvements on Bolivar Peninsula and West Galveston Island that work with the Bolivar Roads Gate System.

    To better understand the proposed Beach and Dune Improvements across the Texas coast, see the StoryMap titled: Beaches & Dunes.

The Bay Side

The Bay defense systems manage the less dangerous, yet still concerning risks caused by storm surge and Gulf surge that makes it past the Gulf lines of defense. Bay defense components include:

  • Ring Barrier System
    An 18-mile Galveston Ring Barrier System that prevents Bay waters from flooding neighborhoods, businesses, and critical health facilities within the City of Galveston. The proposed system has been revised since publication of the Draft Report in October 2018 to incorporate residents’ concerns and comments.

    To better understand this feature, see the StoryMap titled: Ring Barrier.

  • Surge Gates
    Two surge gates would be on the west perimeter of Galveston Bay (at Clear Lake and Dickinson Bay) to reduce surge volumes that push into neighborhoods and thousands of homes around the critical industrial facilities that line Galveston Bay.

  • Pumping Stations
    Because Galveston Island currently operates on a gravity drainage system, the plan would add a forced drainage system consisting of approximately six new pump stations to move water off the island.

    To better understand the proposed Surge Gates and Pumping Stations, see the StoryMap titled: Clear Lake and Dickinson Bay.

  • Additional Protection
    Complementary non-structural measures, such as elevating homes, floodproofing structures and potential property buyouts, to further reduce Bay risks are proposed.

    To learn more about these possible actions, see the StoryMap titled: Real Estate.

Ecosystem Restoration (Bay and Gulf)

Ecosystem restoration addresses habitat loss and provides a natural buffer from coastal storms. Each ecosystem restoration measure represents a combination of features and is formulated in a specific geographic location to restore diverse habitats and provide multiple lines of defense.
