Funding to Diversify Maine’s Island and Coastal Economies



The Tom Glenn Fund Community Impact Fund is a community development catalyst fund that seeks to build a more diverse coastal economy through the investment of capital with planning grants as well as loans and equity support for small businesses. The Fund is made possible through a grant from The Wilbur and Hilda Glenn Family Foundation; daughters Rand and Louisa; and wife, Lou, to honor Tom Glenn II and his lifelong commitment to Maine’s island and coastal communities.



Since 2012, we have invested over $1 million in Maine’s island and coastal communities—with close to $600,000 in small business support and over $400,000 in community infrastructure support for projects focusing on broadband, clean energy, and sea level rise.



The Community Impact Fund offers grant and loan support for small businesses and community infrastructure planning. Business resilience grants and catalyst loans to support small business growth are available for all island and coastal small businesses, including artists and makers and marine small businesses. Grants and revolving loans for community infrastructure planning are available for broadband, energy, and sea level rise.

Community Infrastructure Planning Funding

Broadband Planning Grants

Broadband Planning Grants support community-driven broadband projects in Maine’s coastal and island communities.

The amount of a grant may range from $5,000 to $15,000. An application for a grant serving a large region of communities may request a larger amount. Matching funds are required, and any application with an amount requested that is more than $15,000, or without a 1:1 match, will be considered only if significant need and impact is demonstrated.



Spark! Clean Energy Grants

Spark! Clean Energy Grants fund working waterfront energy projects that improve energy efficiency, switch to renewable energy, and/or reduce consumption of fossil fuels. Projects with environmental and financial benefits, that are highly visible within the community and/or marine sector are more likely to receive funding.

Applicants can receive up to $4,000 per fiscal year. Note: For-profit businesses must provide matching funds for applications. E.g. If a project cost is $5,000 Spark! would fund up to $2,500.

Past projects have supported the purchase of:

  • Heat pumps
  • Solar panels
