The Multnomah Channel Marsh is a 278-acre natural area located on a large floodplain tucked between the base of the Tualatin Mountains (the mountain range that includes Forest Park) and Multnomah Channel, a waterway connecting the Willamette and Columbia Rivers.
Creston Annex houses an early childhood education program for 3 to 5-year-old children, and is located directly adjacent to Portland’s busy SE Powell Boulevard. In 2026, the Estuary Partnership led a project to improve the parking lot and schoolyard by building stormwater management facilities to capture and treat polluted runoff and creating a safe space at the front of the school for student engagement.
