Good Afternoon,
The attached document contains the revised impact exhibit for the culvert and exhibits for the sewer line impacts. I also
included revised figures and some additional photos from the delineation we did for the sewer line.
Thanks,

Good morning Mr. O'Halloran,
I am reviewing the above -mentioned project for your Water Quality Certification. Please include me on the email
with the updated exhibits once you have received them.
Best,

They've corrected the burial depth and made it 12", they used 20% by mistake.

We haven't added the sills and baffles yet, wanted to confirm with you first if that would be acceptable to reduce the
flow rate and keep the native bed material within the culvert.

Ok, so if that's the current slope of the stream, how is it being proposed to keep all of the native bed material within the
culvert? I don't see any sills proposed for this. Why is it being buried a further two inches below the typical 12" for a
culvert that size?

Hi Doug,
Following up on this to see what else is needed before we submit that additional information for the sewer line crossing.
I'm not seeing anything in the NWP 29 about special considerations for the slope exceeding 2.5%, I'm sure slopes are
greater than that in the mountains and foothills all the time. Let me know what you think is needed, trying to get this
one finalized ASAP.

Hey Doug,

I spoke with our civil engineer and the slope that is shown on the impact exhibits is the existing slope of the stream.
Riprap would be placed at the outfall of the culvert to minimize scouring and erosion and really the only way to minimize
the slope is to lengthen the culvert, which would only reduce the slope by half a percent. With the topography they
won't be able to get the slope down to 2.5% -- and they're trying to minimize their stream impacts as much as possible.
As for the culvert burial, they're at 14 inches, does it need to be right at 12 inches?
Can a special consideration be made for the culvert slope to keep stream impacts to a minimum?

Hey Ti m,
Yup send me a "Proposed Impacts Inventory' and I'll add it to the file.

Hi Doug,
Thanks for the feedback. I forwarded your comments to our civil engineer to see what can be done to reduce the slope
and changing the burial depth.
Also, they'll be installing a sewer line as part of the project which would result in a temporary stream impact. Can I
submit the 'Proposed Impacts Inventory' sheet from the PCN word doc for that additional impact or is there something
else that you'd need?

Hey Ti m,
I did have some questions about this culvert. First, why is such a large slope proposed for this? Per the regional
conditions of the NWP 29, culverts of this size 1) should be buried approximately 1' and 2) would need special
consideration for slopes greater than 2.5%. Similarly, how is it proposed to keep the native material within the culvert at
this proposed slope? If as much water is flowing through this culvert as is described and at this slope, I have a hard time
believe the material will stay within the culvert as thus you would lose aquatic passage requirements that are mentioned
again within the regional conditions. If you could get back to me on this, it would be most appreciated.

Good Morning,
I'm reaching out to see if you could provide a status update for the Lincolnton Meadows Phase 2 project.
Could you please provide a timeline for review and let me know if a site visit is needed.
Thank you,
