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 impact, for categorical determination, is the greater of these two measurements. A (width) or B (length) whichever is greater.

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. The linear footage of stream impact, for categorical determination, is the greater of these two measurements.

E. When two or more waters are part of a Single and Complete linear project, the linear footage of the crossing is the summation of all of the crossings that are part of the Single and Complete Project. The impacts for each water being crossed is calculated as described in C and D above.  For the example shown below (in the current PASPGP text), the proposed road is crossing two streams. In determining if the two stream crossings constitute one Single and Complete Project, the distance (indicated by the “?”) between the two streams is taken into consideration. If the crossings are not distant, meaning that the location of the first crossing dictates the location of the second crossing, then the two crossings are considered to be one Single and Complete Project. In the example, the distance between the two streams is undefined (indicated by the “?”) because determinations must be made on a case by-case basis based on the proposed project. Linear projects such as roads do not allow for abrupt changes in layout, thus requiring a greater distance between resources for each crossing to be a separate Single and Complete Project. Small utility lines may change direction over a much smaller distance and result in the distance between separate Single and Complete Projects being less. For the below example (in the current PASPGP text), both crossings have been determined to comprise one Single and Complete Project, and the linear footage of stream impact for the Single and Complete Project is calculated as Stream 1, Measurement A + Stream 2, Measurement B = Linear footage of the Single and Complete Project.   

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.
