Today, we're spotlighting a project that's helping restore and protect a vital local waterway.

The Jacob Reiff Stream Restoration Project has improved more than 1,200 linear feet of degraded streambank within Jacob Reiff Park (in Harleysville, PA), reconnecting the stream to its floodplain and reducing erosion and sediment loss throughout the watershed.

ARRO has worked alongside Lower Salford Township and the Perkiomen Watershed Conservancy to bring this two-phase project to life, providing engineering design, survey support, and regulatory coordination along the way.

With Phase 1 complete, and Phase 2 construction currently underway, the project is helping create a healthier, more resilient stream corridor for the Township, local wildlife, and the broader Perkiomen Creek watershed.

We're proud to support projects like this that help protect natural resources while creating long-term value for the communities they serve.
