Hi Amy,
I’m following up on your email below. I’m in agreement with the upgrades proposed.
My concern would be compac?on of na?ve material and rip-rap used under the perched culvert to prevent further
scouring.
Based on the photos and the low stream flow depicted, addi?on of a plunge pool would increase stabiliza?on at the
culvert outlet but it should also avoid restric?on of water flow in dryer periods. Let me know if you need further
assistance.
Thanks

Steve and Ryan,

Steve, per our conversa?on, we are going to install a plunge pool lined with rip rap at the pipe outlet. The revised plan is
included below. Its our understanding that a permit modifica?on will not be required since the plunge pool will not be a
loss of water. Ryan, I’ve included a picture of the current perched pipe. These were provided to Dave
previously. Please advise if you have any ques?ons.

We would take the material that is in the exis?ng bank along with rip rap and build the channel up. The exis?ng material
is typical of the piedmont and a mixture of silt, clay and small cobble. We would not add any red clay to the stream. The
channel as installed too narrow, so we will open that up to the appropriate width, and use any suitable material in the
stream. We aren’t opposed to using only rip rap if that is what ya’ll prefer. We suggested na?ve material because we
are hoping to keep the impact from being deemed a the ‘loss of water’. We’ll see what Steve has to say, and go from
there.

Dave,
Please see a?ached photos. As we need to widen the channel at the turn and that rip rap can be reused for this purpose
I’d es?mate we wouldn’t need to supplement with more than a ton to complete what’s needed.

Let me know if you need anything else on this.

Thanks,

Hi Amy,
What will the na?ve material consist of? I’m thinking that if it is mostly sand/gravel that it
would likely be flushed out during the next storm event. Wouldn’t rip rap alone take care of
the perch and allow upstream sediments and na?ve material backfill riprap voids over?me
with subsequent storm events? Just wondering what the best approach might be. If possible,
could you send a couple of pictures of the perched outlet’s exis?ng condi?on and channel and
es?mates of amount of riprap needed? Not sure about a formal permit modifica?on at this
?me. I would like to hear the Corp’s opinion.

Thanks for the no?fica?on.

We have a small pipe perch at permit site 19 on the U-2579AB project. We propose to place rip rap mixed with na?ve
material to the stream bed to bring the stream bed eleva?on up to the exis?ng pipe. If we combine rip rap with na?ve
material, can we proceed without a permit modifica?on? The addi?onal rip rap/na?ve material combo would be within
the are permi?ed as bank stabiliza?on. In the picture below, there is purple text and an arrow to the loca?on.

Thanks.
