The comment period was originally scheduled to end Jan. 9, according to a Corps news release.
Several people, including U.S. Rep. Randy Weber, R-Friendswood, and Galveston County Commissioner Ken Clark, requested a 45-day extension on the comment period during a Dec. 18 meeting on the study.
"Public involvement is integral to assessing the environmental consequences of the proposed project and improving the quality of the environmental and feasibility decision-making," the Corps' release reads.
