Stormwater Management on Public Lands

Altogether, this suite of projects represents various partners, types of practices, and varieties of land. This allows the Schuylkill Action Network (SAN) to test its theories about public lands, assess which best management practices (BMPs) are most effective, and consider what levels of effort and cost should be involved. They also provide built in educational opportunities for visitors to such sites regarding threats to the Schuylkill River due to stormwater, as well as the impact that BMPs can have in helping to improve water quality conditions. Because public lands in the watershed are typically large tracts with one title holder, fewer logistics and administrative costs for stormwater management projects are anticipated. Public landowners may also be more willing partners, and the maintenance personnel associated with these tracts can help to ensure proper long-term implementation of BMPs.

There are six stormwater management demonstration projects on public lands utilizing Schuylkill Watershed Initiative Grant funding from the Partnership for the Delaware Estuary, each with its own local project manager:

• Brookside Country Club
This project, managed locally by the Delaware Riverkeeper Network, involves dam removal and stream bank restoration at a high-priority, municipally-owned golf course in the Schuylkill Watershed.

Thanks to the Montgomery County Conservation District, an integral SAN member, this Stoney Creek stream bank in Norristown Farm Park now serves as a demonstration site where others can learn about riparian buffers, their stabilization and the value of such projects.


Status
: In 2006, the planning and design phases were completed for this site, and implementation got well underway. The Delaware Riverkeeper Network installed four fish-habitat structures — including a rock cross vane and three log vanes — removed gravel bars, and stabilized approximately 12,000 square feet of stream bank through the use of newly installed plants.

• Riparian Buffer & Stormwater Retrofit Along Wissahickon Creek
This project, managed locally by the Borough of Lansdale, involves the design and installation of a stormwater outfall retrofitting project in the riparian buffer of a public park located at the headwaters of the Wissahickon Creek.

Status: The majority of the final engineering and design work for this project was completed in 2006, including the initial determination of permitting requirements. Construction will get underway sometime in 2007.

• Norristown Farm Park Project
This project (see photograph) is being managed locally by the Montgomery County Conservation District, and it involves invasive-species removal and riparian-buffer installation on parkland adjacent to Stony Creek.

Status: Invasive plants have been removed and a “living berm” has been installed on a steeply eroded bank of Stony Creek, adjacent to a popular stream-access location. Furthermore, educational signage has been installed. The planning and design of floodplain-restoration work in a former ballpark area is also complete. Additional plantings in the “living berm,” as well as structure removal and restoration efforts of the ball park area, are set for 2007.

• Riparian Buffer & Bio-infiltration at Norristown High School
This project, managed on the local level by the Norristown Area School District, involves the installation of a native riparian buffer, as well as the construction of bio-infiltration pockets for parking lot drainage at a high school located along Stony Creek.

Status: The planning and design of a riparian buffer was complete as of January 2007, and 200 trees and shrubs have been planted by volunteers who are largely from the school and community. Final design and engineering plans have also been completed for stormwater/bioinfiltration components of the project, and preparations are being made to select a contractor.

• Spring-Ford High School Stormwater Basin Naturalization
Locally managed by the Montgomery County Conservation District, this project involves the naturalization of a stormwater detention basin at Spring-Ford High School to help treat stormwater runoff draining to the basin from a large parking lot and several playing fields on the school’s campus.

Status: Contractor selection is underway for implementation work.

• Stormwater Management Technical Assistance for Schools
This project, managed by the Philadelphia Water Department, will provide technical assistance from a consultant to establish a conceptual design for effective stormwater management controls and retrofits at two schools in the watershed.

Status: Two schools have been identified and are under cultivation.
