According to the PA State Programmatic General Permit, the linear footage of stream impact should be measured as follows:
A. For regulated work on one stream bank, the linear footage of stream impact should be measured along the bank being impacted. When both stream banks are being impacted at separate locations, the linear footage of stream impact is also measured along the banks being impacted.
B. For regulated work proposed along both stream banks, where at least a portion of the work on the opposing stream bank is overlapping, the linear footage of stream impact should be measured along the centerline of the stream. C. For transverse impacts (perpendicular to the stream bank), the linear footage of stream impact should be measured from the top of the opposite bank and from the upstream to downstream limits of work. The linear footage of stream impacts is the greater of these two measurements.
D. Dewatering – if work involves dewatering of a stream channel, measure the centerline of the stream channel that is impacted through filling, dewatering, and/or flooding, and measure from top of stream bank to top of stream bank. linear footage of stream impact is the greater of these two measurements.
This calculation should be performed based upon the best information available when the NEPA document is completed. This calculation may change during final design or construction, and such a change is acceptable. The CEES requires a numeric answer for this field for reporting purposes.
