Winterbrook is assisting NNA Landscape Architecture with environmental documentation and permitting for trail and shelter improvements at the Columbia Children’s Arboretum. Winterbrook provides guidance on park design, which include trail improvements, new ADA access, new shelter and park furnishings, and native plantings to enhance Columbia Slough riparian habitat.

The area around the site was proposed as a park in 1904 by landscape architect John Charles Olmsted.
