Abstract:The primary objectives of this project included: Assessing the vulnerability to flooding of critical assets using the Boston Harbor – Flood Risk Model (BH-FRM) developed under a previous FHWA grant. Evaluating alternatives to address identified vulnerabilities. Developing bid documents for a selected alternative at the MassDOT Tunnel Egress TE-434 and MBTA Blue Line Aquarium Station. Constructing the selected floodproofing alternative as quickly as possible to make the TE-434 and MBTA Blue Line Aquarium Station resilient to coastal flooding. Developing Standard Operating Procedures for deployment of temporary flood barriers. This report summarizes the project needs, the scope of work performed, interagency partnerships, the approach and methodology, development of Standard Operating Procedures for the deployment of Flood barrier systems, future monitoring and documentation and lessons learned over the course of this project. A Standard Operating Procedure (SOP) is being developed, that identifies responsible parties for decision making, forecasted flood level thresholds used to trigger deployment, personnel in charge of barrier deployment and communication protocols.
