RICHLAND, Wash. – The U.S. Army Corps of Engineers, Walla Walla District (Corps), invites public comments on proposed improvements for a section of the multi-use Duportail Trail. The trail section would follow the alignment of a gravel path that is located along the northeast shoreline of the lower Yakima River from the Chamna Natural Preserve to Duportail Street in Richland, Washington. This trail would be located entirely on Corps-managed lands.
