Forest Park Trail Work: Rock Armoring and Drainage Work on Newton Road Trail

NWTA Volunteers Improve Newton Road Trail in Forest Park

It cannot be understated what 13 motivated and skilled people can accomplish when given a clear vision and a common goal. The results of this effort are now visible on the lower section of the Newton Road Trail in Forest Park.

Collaboration with PP&R Addresses Long-Standing Trail Issues

Working in collaboration with Portland Parks and Recreation’s trail team, NWTA volunteers tackled several long-standing issues along this section of trail. The crew addressed multiple drainage problems, widened a narrow trail bench in an exposed area to make it significantly safer to traverse, and rock armored a notoriously muddy stretch of trail.

Learning Stone Pitching and Rock Armoring Techniques

Along the way, volunteers learned about stone pitching, a rock armoring technique where medium-sized stones are set on end like books on a shelf. When placed correctly, the flat faces of the rocks lock together to form a strong structural membrane. This method helps raise the trail tread through flat, poorly draining terrain while allowing water to drain through the rock, resulting in a more durable and sustainable trail.

Building a Causeway Through Muddy Terrain

To bring the causeway to life, volunteers used rocks staged for the project along with a remarkable number of wheelbarrow loads of ballast. Rocks were carefully fitted together like puzzle pieces, with crushed rock packed into every crack and crevice. At the same time, another group uncovered a nearly hidden culvert and dug a small ditch parallel to the trail to help move water out of the surrounding swampy area. It was muddy, mucky work, and deeply satisfying.

Volunteers Power Through Heavy Work with Momentum and Humor

Once water was flowing freely and the larger rocks were locked in place, the trail tread was finished with ballast. Load after load of crushed rock was moved by wheelbarrow. Despite the physical demands, the crew powered through with humor, smiles, and steady determination.

What Comes Next for Newton Road Trail

By the end of the day, the crew had outworked their materials, running out of larger rock before the causeway could be fully completed. PP&R’s trail team will return in the coming weeks to wrap up the final section and complete the project.
