KeyBank Foundation has donated $450,000 payable over three years to Coastal Enterprises Inc. to support small business growth and job creation in Maine’s rural counties, the financing organization said Thursday. The grant, approved as part of KeyBank’s $16.5 billion National Community Benefits Plan, will provide new support for CEI’s small business lending and advisory services, and partnerships with local organizations to help grow economic opportunity and quality jobs in rural Maine, it said. “We are grateful for KeyBank’s recognition of the challenges and opportunities that Maine’s rural regions face as they work to grow more – and better quality – jobs and environmentally sustainable enterprises,” said CEI CEO Betsy Biemann in a news release.
