Based on public input, several additional and optimized combinations of alternatives are being evaluated. The alternatives will be weighed against the project objectives and potential environmental impacts to determine a preferred alternative that, when implemented, would maximize flood protection and minimize adverse impacts to adjacent communities and the environment, seek to minimize requirements for new land easements, and, where possible, incorporate green infrastructure. The Draft EIR is planned to be released by early 2019 and will include a public comment period. Simultaneously, the U.S. Army Corps of Engineers is preparing a similar federal document, an Environmental Impact Statement (EIS), to potentially aid in the implementation of a project.
