Madrone Wall Concept Site Plan

On HoldThis project is currently on hold.

The site was purchased in the early 1900s by the County for use as a quarry. In recent years, the Clackamas County Board of Commissioners (BCC), with input from local citizens, decided to recommend the site become part of an area for Clackamas River Watershed Protection and designated the site as a priority for master planning. The property is in the County’s current inventory of timberland. Wetlands are present along the road and be considered for development of Clackamas County Parks.

The defining physical feature of the site is the 120-foot high basalt wall that bisects the property, which has previously provided opportunities for local rock climbers. While hosting striking examples of the namesake Madrone tree and possessing sweeping views of the nearby Clackamas River, the site also contains invasive plant species and has been used for illegal dumping. Previous quarry activity has left the site with a considerable number of roadbeds and previous recreation activity has created a network of trails. The site is currently not open to the public.

Previous citizen input has indicated that the undeveloped nature of Madrone Wall is one of its appeals, and numerous studies confirm that the site is of value to native flora and fauna. Balancing the potential development of recreation with the need to preserve and enhance the site’s natural resources will be one of the primary design challenges and will result in the creation of a concept plan for possible future development.
