The Coastal Resilience Engineering Design project aims to enhance the resilience of Bath Maine's coastline against the impacts of climate change and flooding, including sea level rise, storm surges, riverine events, and coastal erosion. This project will involve the development of engineering solutions to protect infrastructure, natural habitats, and communities. In 2023, the City of Bath, Maine assessed the vulnerability of infrastructure and open spaces (i.e., wetlands and conserved land) to flooding from storm surge, sea level rise, and extreme riverine events throughout the entirety of Bath's coastline. The purpose of the work was to evaluate present-day flood risk, flood risk in 2050, and flood risk in 2100 and recommend next steps towards adaptation, including timelines for when adaptation measures should be in place to limit the impact flooding may have on people, places, and infrastructure within the City. The results (i.e., water surface elevation, depth and extent of inundation, duration of inundation) of the flood vulnerability assessment were compiled and organized by land use: transportation, buildings, industries, public safety, power, pump stations, open spaces, and ports. The results for the 15 flood scenarios are summarized in the report and its attachments (figures, tables, and appendices). This study identified the following key assets that warrant adaptation in the near-term based on two critical flood scenarios:
o For present-day sea levels, approximately 1.1 miles of roadways, 44 residential buildings, 4 remediation sites, 4 pump stations, and 146.2 acres of wetland not likely already experiencing flooding due to average daily tides would likely be inundated during combined 1% annual chance ("100-yr") coastal storms and riverine events.
o For average daily tides and average daily streamflows in the year 2050 and assuming 1.5 ft of sea level rise, approximately 0.1 miles of roadways, 13 residential buildings, 2 remediation sites, and 73.8 acres of wetland not likely already experiencing flooding due to average daily tides would likely be inundated during high tides. Anticipated scope of services may include but is not limited to the following tasks: o Identification, development, and preparation of federal, state, local, and private grant applications to fund work, and then implement work funded under those grants, including grants originating with, but not limited to Congressionally Directed Spending (CDS), the Maine Department of Transportations' Infrastructure Adaptation Fund (MAIF), the Federal Emergency Management Agency (FEMA), Maine Emergency Management Agency (MEMA), Maine Community Resilience Partnership Grants (GOPIF), and Maine Coastal Program Grants. This work will also include both pre-award and post award engineering services and management for Hazard Mitigation Assistance (HMA) project(s) and/or projects(s), if awarded.
o Asset Management, condition assessment, planning, design, permitting, and estimating probable construction Costs; bid document preparation, bidding assistance, construction management, oversight and inspection (either full-time or part-time as necessary); as-built drawings and operation and maintenance plan preparation for various public infrastructure improvement projects.
o Investigating and quantifying existing conditions of various public infrastructure, including the preparation of engineering
o Conducting assessments and reviewing current coastal resilience plans for the City of Bath.
o Developing and evaluating coastal resilience strategies and solutions.
o Designing and recommending engineering interventions.
o Collaborating with stakeholders and other professionals.
o Preparing technical reports and documentation.
o Providing expert advice and recommendations. The City reserves the right to evaluate the submitted proposals, waive any irregularity therein, and to select any firm(s) which submits a proposal and/or reject any or all proposals should it be deemed in the best interest of the City.
