Bristol Sea Level Rise Scenarios

The following scenarios were developed by the Maine Geological Survey in conjunction with the Lincoln County Regional Planning Commission for general planning purposes only. They are based on a “bathtub” simulation model and do not take into account impacts associated with erosion, accretion, or wave action. Though local, regional, and national data indicates that sea level is continuing to rise, scientific authorities cannot predict with certainty the precise increase that will be experienced along Lincoln County’s tidal shoreline. Communities are advised to consider the information provided by this project as part of a “scenario-based approach” and create adaption strategies to mitigate impacts on natural systems, public infrastructure and facilities and existing and future development.

Please note the following when viewing the scenarios:

· When a road segment or a rail line is predicted to become inundated it is usually highlighted in black or gray. On occasion the highlighting may be absent so the best indicator of inundation is whether water is shown crossing a road or rail line.

· Buildings are highlighted in red when water is predicted to be present at the building’s foundation during a given scenario. The scenarios themselves do not present information on the depth of water, only that some level of water is present at the building’s foundation.

Inundation Depths

The following PDFs present predicted inundation depths for selected scenarios at selected locations within the community:
