Susquehanna-Roseland Transmission Line
Northwestern New Jersey
PSE&G Services Corporation
AKRF developed habitat restoration plans for PSE&G as part of the Comprehensive Management Plan (CMP) for 26 miles of disturbed right-of-way for the electric utility company’s Susquehanna-Roseland Transmission Line.
Since the transmission line passed through the environmentally sensitive Highlands Region and the Delaware Water Gap National Recreation Area, agencies including the National Park Service, the New Jersey Department of Environmental Protection, and the New Jersey Highlands Council all had an interest in seeing that wildlife habitats and vegetation were properly restored following of the required access roads and upgraded transmission towers. While the CMP included sketches to illustrate the measures promised for mitigation of disturbed areas, it soon became clear that more detailed plans would be required by the contractors in order to build the recommended habitat improvements.
To translate the science-based proposed measures into realistic construction documents, AKRF landscape designers and environmental scientists worked with other consulting biologists to develop detailed plans for elements such as wildlife crossings, hibernacula, brush piles, wood turtle nesting sites, and Indiana bat roost enhancements—just to name a few.
And because actual conditions in the field can require on-the-spot modifications, we were also called upon by the field biologists to quickly modify the construction documents, often producing hand-drawn plans for the contractors so construction could proceed on schedule.
Below are examples of our illustrations for this project. On the left is an American Kestrel Box. AKRF created this construction detail and illustration as part of the CMP restoration plan set and report. Each bird species has very specific requirements for nest box and entrance opening sizes, and mounting height and location. AKRF identified suitable habitat throughout the transmission right-of-way for potential American Kestrel nest box placement.
On the right is a Wildlife Crossing Tunnel. AKRF prepared this wildlife access road crossing tunnel detail to assist contractors with appropriate construction methods in the field. Several types of animals may benefit from using wildlife crossings, including small mammals, amphibians, and reptiles, such as the wood turtle.
