Sills are strongly recommended at the upper and lower end. They hold the grade and allow
the fill right up to the inlet/outlet. Typically the stream is lower in elevation, and then the
culvert is just set at a lower elevation, but NOT buried. See illustration and photo of a buried
culvert.

Well being buried is, but not necessarily the inclusion of sills on the culvert. That's something we add depending on
the situation.
Thanks,

Will do. Aren't those conditions of the certification generally already?

Ok, so that looks good for the culvert, BUT you'll need to make sure there are sills on both ends of the culvert and it
is properly buried.

Hey Sean,
Do you have another format for those pictures? We can't open them up in our system.

Alan and Doug,
The attached photos were taken by the engineer in the location of the proposed crossing. He did not pull a tape but
hopefully you can get a pretty good gauge of the stream width.
Let me know if there is anything else you need for the review of the permit application.
Thanks

We are requesting a photo of the stream where the culvert is crossing. The culvert is 11 ft
wide. Which is a pretty wide culvert. The question we have is what is the width of the base
flow of the channel. Typically streams are wider than typical everyday base flow. Ex. For this
7

11 ft wide culvert, the base flow may only be 3 ft wide. Which would mean that culvert is way
to wide to properly pass base flow conditions. Thus we would require baffle, ext.
We were asking for stream photos to provide clarification of what base flow was relative to
the width of the channel (culvert needs). Again culverts are design to pass large storm events
and thus are oversized (my words) for passing base flow.
So, if you have a photo of the stream, that may answer the question. Or Doug can do a site
visit.
Thanks
Alan

Gentlemen,
The NW 29 permit was issued on October 22, 2021. I think the best path forward in to completely address all
your concerns would be to schedule a Teams meeting so we can better understand everything you need so
the 401 Certification may be issued. If you agree with this proposal, please provide some dates that would
work for you all.
Best regards,

Hi Ian,
I talked with Alan on this one. So I get that you're digging out to bury this culvert. So first, our concern is that once it's
buried, native material won't be put back into the culvert, thereby "burying" it. We've recently had some sites that have
done that and now have headcutting issues that they now have to come back and fix. Second, we also had concerns
about the size of the culvert. Do you have pictures of the stream, post -dam removal, so that we can put the stream and
culvert better into context?
Thanks,
Doug

Doug and Alan,
Please see the attached map> The stream will be pumped around, the culvert stream bed location will be excavated
slightly to allow for the culvert to be buried a foot beneath the existing bed, and then fill will be placed on top of the
culvert to bring the road up to the proposed grade.

Hi Sean,
Thanks for getting these to me. I did have a few more questions. Do you have a picture of the stream post -beaver dam
removal? Second, how exactly is the culvert going to be buried? I have concerns that a culvert that big won't be properly
buried 1' and that we'd wind up with unintentional stream impacts.
Let me know,
Doug

Doug,
I attached the culvert cross section which should have been attached to the original submittal. Let me know if you need
any other impact mapping.
The attached photo is from the winter of 2017 at a point slightly upstream of the proposed crossing location. When we
went back to the site the following year the beaver dam had blown out and the stream was back to its normal size of
about 10-12 feet. The stream is pretty deeply incised so that the top of the gully is maybe 4 to 5 feet deep. The stream
itself is maybe 0.5 to 2 feet deep (in pools) but is usually a little shy of 1 foot deep.
Hope that answers your question but if not give me a call.
Thanks

Hello,
10

I am emailing you today about your ePCN application. Do you have better more representative photos of the stream you
are crossing? Also, do you have a cross sectional view of the culvert you plan on putting in? Is the baseflow of the stream
actually 12' wide or are you measuring the whole channel?
Let me know,
