The Cathance River Education Alliance was created in 2000 as part of a land-use agreement between Highland Green Developer John Wasileski and the Topsham Citizen group, Topshams Future. It quickly became a living partnership that included the Brunswick-Topsham Land Trust, area educators, various members of Highland Green residents and interested area citizens.
