Rose Valley Creek Retrofit Design


In October 2009, the Friends of Borough Park in Ambler began an effort to restore 3.5 acres of the park bisected by Rose Valley Creek. The riparian buffer that had been established had become overgrown with invasive species, including multiflora rose, bamboo, Norway maple, Japanese knotweed, and other invasive species. The first phase of the project focused on invasive plant removal. Grant funds from the TreeVitalize program will be used to purchase native species that will be planted in the buffer, expanding the buffer’s width from 10 to 50 feet. In addition to reducing flooding downstream and reducing the amount of nonpoint source pollution entering the stream, the buffer also provides streamside habitat for small wildlife.

Other restoration projects to be installed at Borough Park are a rain garden and a meadow. These will replace existing turfgrass, which provides less infiltration of runoff. The meadow will be planted with native grasses, and will be mowed to create walking paths. The project also features a public education component focused on increasing stewardship of the stream as a valuable natural resource.

This project is expected to be completed by October 2010.
