Greenway NHA Public Comment Opportunity

The Mountains to Sound Greenway National Heritage Area (Greenway NHA) is a unique geographic corridor made up of connected ecosystems and communities spanning 1.5 million acres from Seattle to Ellensburg along Interstate-90. The diverse and dramatic landscape has shaped the region’s history and is interwoven with its culture and character. NHAs are places designated by Congress where historic, cultural, and natural resources combine to form cohesive, nationally important landscapes.

As the coordinating entity for the Greenway NHA, the Mountains to Sound Greenway Trust is pleased to share a draft Management Plan for public review and input from May 20 – June 20, 2022.

The Greenway NHA Management Plan describes a framework of Themes that convey the rich history and heritage of the Greenway NHA, and it recommends partnerships, strategies and priorities for historic preservation, natural resource conservation, responsible recreation, heritage tourism, and interpretive projects and activities. The plan was created over the last two years with input from hundreds of contributors including historical societies, conservation and recreation groups, government agencies, tribal governments, local businesses, and interested community members across the Greenway NHA.

Get Involved in the Planning Process!

The public comment survey for the draft plan was open for comment from May 20 – June 20, 2022. Now, the Greenway NHA planning team is reviewing all input and creating a final draft of the Management Plan to submit to the National Park Service for approval by the Secretary of the Interior.

Thank you to all involved in the public comment process, we appreciate your time and input!
