Two Portland-based nonprofits this week announced plans to address affordable housing challenges in neighboring New Hampshire.

Evernorth, a nonprofit with dual headquarters in Portland and Burlington, Vt., said it will oversee a workforce housing loan fund for the Upper Connecticut River Valley, which includes parts of New Hampshire and Vermont. Bar Harbor Bank & Trust is a key partner on that.

Closer to Maine, in Conway, N.H., Avesta Housing, broke ground on its first affordable housing development in Mount Washington Valley on Sept. 23. Bangor Savings Bank is a partner in that venture.

Avesta is the largest nonprofit affordable housing provider in northern New England.
