Island and coastal communities are on the front line of the impacts associated with sea level rise, a persistent and long-term problem.

The predicted impacts on homes, businesses, and critical infrastructure, including working waterfronts, could structurally change the communities and economies along our coast. These changes may happen over a long period of time, or they may happen abruptly if we are hit with a large storm.

Island Institute partners with coastal and island community leaders to address the impacts of sea level rise. Through research, outreach, advocacy, and financial support, we help businesses and municipalities along the Maine coast plan and build infrastructure that improves their resilience to rising seas and other climate change effects.

ShoreUp Grants

Much of Vinalhaven’s downtown and working waterfront can be underwater during several high tides throughout the year.

Funding for community Sea Level Rise preparedness

Communities along the Maine coast are taking steps to address coastal flooding exacerbated by sea level rise. Each community faces unique challenges particular to their working waterfront, existing infrastructure, and citizen engagement. Because of that, each community is taking a different approach to planning for the impacts of rising seas.

Island Institute’s ShoreUp Grant offers flexible funding and support, so that communities can plan for the assistance they need to start taking the steps that are right for them. ShoreUp Grants offer funding support (up to $10,000) for Maine island and coastal communities as they assess, implement, and/or plan for sea level rise. Sea level rise preparedness projects might include (but are not limited to): risk assessments, infrastructure and natural resource planning, and community engagement programs related to sea level rise.

Tools to Help Guide Your Community

Sea level rise impacts communities in a variety of ways, requiring unique solutions to meet their individual needs. Some are seeing threats to their downtowns, others have working waterfront infrastructure at risk, still others are concerned about underground utilities, water supplies, and wastewater treatment plants being inundated.

How can your community become more resilient to sea level rise?

  • Start the Conversation: Initiate community conversations through town meetings, informal discussions, documentation of inundation and other impacts​ and active networks with others grappling with similar problems.
  • Risk Assessment: Better understand the risks related to storm damage, and how these risks are projected to change due to sea level rise through a risk assessment.
  • Formalize a Plan: Translate this increased understanding into informed decision-making and actionable steps to enhance resiliency by formalizing a plan.
  • Funding and Adaptation: Secure funding and begin construction of mitigation and adaptation measures. ​

  • Sea Level Rise Basics: For a basic primer on what sea level rise is, the impacts to coastal communities, and some attainable steps see Sea Level Rise and Coastal Flooding: The Basics for Maine Communities.
  • The Cost of Sea Level Rise: Check out the first in our three-part Economic Impact Study – The Cost of Sea Level Rise – Vinalhaven Edition – an interactive story map that walks one through the challenges faced by an island community.
  • Flood Resiliency Checklist: Take a look at the Maine Flood Resiliency Checklist, a self-assessment tool for Maine’s coastal communities to evaluate vulnerability to flood hazards and increase resilience.
  • Solutions Library: To share stories around the challenge of planning for sea level rise resiliency, and provide additional resources to help communities here and beyond, we continue to develop our What Works Solutions Library. Solutions in the library highlight community struggles to protect working waterfront infrastructure and downtowns from impending inundation and some of the steps being taking to address these issues.

A Climate of Change: Sea Level Rise

The fifth film in our ongoing climate-related documentary series, A Climate of Change: Sea Level Rise follows the community of Vinalhaven, Maine, over a two-year period as they have conversations around planning for and responding to sea level rise on the island. It highlights some of the challenges they face, but more importantly, shows us how a small, yet engaged community can lead the way to planning for change.

Sea Level Rise in Maine

Sea Level Rise is Happening! Created for the Island Institute, this O’Chang Comics / Puckerbrush Animation original calls attention to the challenges of increased coastal flooding, storm surge events, and sea level rise impacts for Maine communities.
