Subject: Middle Fork Greenway Section 4 - questions
Hi Mr. Furman,
I am reviewing the 401/404 application for the Middle Fork Greenway and have a few questions:
I. Where is the greenway in relation to the Middle Fork New River along the 4275' stretch (how far away
from the river is it?)?
2. Why is a temporary crossing needed for the Middle Fork of the New River for the stabilization section?
3. Will the stone used for the temporary crossings be removed once the crossings are no longer needed?
4. The PCN states that the UT to Elrod Br will be culverted with a 24" HDPE culvert, but the photo sheets
state that it will be crossed with an arch culvert. Which is it? We much prefer an arch culvert.
5. Likewise, is it possible to change the UT to Middle Fork New 36" HDPE culvert to an arch culvert? What
length will the impact be (it's stated that it'll be 18 ft in the text and 24 ft in the impact table). We also
recommend against using HDPE material for culverts, as it is difficult for aquatic animals to move through
these slick culverts.
6. For the Middle Fork South Fork New River stabilization:
a. Will you be sloping the banks? If so, at what slope?
b. Can you isolate the work areas from the thalweg using a coffer dam? This is important especially at
bank work areas - e.g., toe wood, j -hook tie ins, boulder toe.
c. Will you be working from the bank or from within the river itself?
Thank you,
Andrea
