The Washington State Department of Natural Resources (DNR) has approved the addition of approximately 2,100 acres to the Mt. Si Natural Resources Conservation Area.

“The addition of these lands to Mt. Si will enhance one of the most popular conservation and recreation areas in the Greenway,” says Cynthia Welti, Executive Director of the Mountains to Sound Greenway Trust.

“With this addition, the Mount Si NRCA is now protecting more than 12,000 acres from development in eastern King County,” said State Public Lands Commissioner Peter Goldmark.

The expansion will extend the Mt. Si conservation area boundary to the banks of the Middle Fork of the Snoqualmie River.

The Mountains to Sound Greenway Trust coalition has been working over the past two decades to conserve lands on and around Mt. Si through public ownership. The Greenway Trust in partnership with the Washington State Department of Natural Resources has undertaken major trail improvement projects on the 4-mile Mt. Si Trail and the 2.5-mile Little Si Trail over the past several years.
