Abstract: The Coastal Texas Protection and Ecosystem Restoration Feasibility Study, also known as the Coastal Texas Study, was undertaken to determine the feasibility of constructing coastal storm risk management and ecosystem restoration features using a multiple lines of defense strategy along the Texas coast. The project feature selection process resulted in six coastal storm risk management options and nine large-scale ecosystem restoration features that were evaluated for engineering, economic and environmental viability and reviewed under the National Environmental Policy Act, to determine feasibility for Congressional consideration. The Final Environmental Impact Statement (FEIS) discloses the anticipated effects to the natural and human environment from the alternatives considered based on the best available information at the time of publication. The EIS employs a tiered-NEPA approach in which full environmental compliance with NEPA and environmental laws has been demonstrated for “actionable measures,” which primarily consist of ecosystem restoration actions where the impacts and designs are well understood and minimal changes are anticipated during the preconstruction, engineering design (PED) phase. For measures referred to as Tier One measures, some uncertainty remains on the design of the measure or additional modeling is needed to fully understand and quantify the effects of the action, so the disclosure of impacts at this phase is an overview of the worst-case scenario to give the decision maker a full understanding of the possible impacts. For these measures, additional NEPA will be completed during PED to more accurately disclose the impacts based on refined designs and updated modeling. Significant impacts to natural resources are expected with implementation of the coastal storm risk management measures (CSRM), while impacts would be less than significant for ecosystem restoration (ER) measures.
