The Last Green Valley National Heritage Corridor generates $303.3 million in economic impact, supports 3,630 jobs, and generates $25.8 million in tax revenue annually, according to a study released last week.

The Last Green Valley is comprised of 35 towns in Connecticut and Massachusetts, including Griswold, Norwich, Plainfield, Preston, Sprague, Voluntown and Lebanon.

The figures in the study were developed in an Economic Impact Study produced by a consultant using standardized methods developed to evaluate National Heritage Corridors around the country, corridor officials said in a news release.

Visitor and tourism expenditures at partner sites account for the largest economic impacts, according to the study. From corn mazes, country fairs and historic houses, to antique shows, street festivals, museums, and regionwide events such as Walktober, almost 1.9 million people spend money annually on a wide range of activities and attractions throughout The Last Green Valley National Heritage Corridor, the study said.

According to the study, “The development of hiking trails, paddle guides, and signature events such as Walktober has allowed TLGV NHC to become a tourist destination. Increased tourism in the corridor has spurred economic and community development with the creation of businesses that provide needed services to visitors. TLGV has been able to balance its endeavors in preservation and development to ensure the quality of life is enhanced, while upholding the integrity of the region. As TLGV continues to pursue grant opportunities, work with local organizations and business, and find ways to provide cultural and recreational opportunities for visitors, the NHC moves forward in fulfilling its vision for the region.”

The study is the second comprehensive study that has been conducted in the National Heritage Corridor over the last two years. This past fall, the National Park Service released its recommendations for continued support of The Last Green Valley National Heritage Corridor.
