Land and environmental record

Dated Land Use Breakdown

2006

2006 license-renewal environmental report: PPL Susquehanna owned 2,355 acres; 1,574 acres on west side of river (1,173-acre SSES property, 401-acre Riverlands Recreation Area); 717 acres on east side. Developed portion was approximately 487 acres, including approximately 233 acres inside the Protected Area.

These are dated owner and land-use figures from the license-renewal environmental report and differ from the later 2,347-acre owner statement. Kept separate because they represent different time periods and allocation methodologies.
