An email approval for the stormwater management plan is attached.
Here is a summary of the stormwater plan:
10.0 CONCLUSIONS
. - 2-_ 10-, and 100-year 24-hour peak control for the overall watershed is met -.without water quantity
controls, refer to Table 1,
1-year 24-horn peak control for the site is met with the use of the three proposed baoretcutiott
cells_ refer to Table 2.
- Bioretentiolt cells are desisted to meet 851:!o TSS removal
▪ Bioretention cells along with off -site mitigation to meet required nitrogen and phosphorus loading
rates
The plans & calc package can be provided at your request.
If you need anything else to help in your review, please let us know.

I am swamped right now, so it will probably be a couple of weeks before I can finish my review.
i

If there is an increase in the amount of buffer mitigation required, then a SOA needs to be provided that accounts for
the increased buffer mitigation. Additionally, if the original SOA hasn't been paid, you probably need to get a new SOA
anyway because those credits may no longer be available. I don't remember the language used in the SOA provided in
Version 1 off the top of my head.
Is the SMP for the site approved? Can you please provide a copy?

Good afternoon Colleen,
I'm jumping in for Taylor here. Please see responses to your comments below in blue as well as the attached comments
from the City of Durham. Please review at your convenience and let me know if you have any additional questions or

comments. Assuming you have everything you need, do you have any idea when you may be able to process the
modification? Any rough estimate would be greatly appreciated so that we may relay the information to the applicant.

Hi Taylor,
It is 60 days, which is today. I'm looking at it now, and I need some more information:
1) The cover letter mentions that a new SOA from EBX should be attached to the package for the required buffer
mitigation, but I'm not seeing it. Can you please send me a copy of the SOA? The previous SOA dated 8/6/21 is
for 45,102 SF. Our modification is to increase to 47,033 SF. Do we need to request a new SOA?
2) The cover letter says that Impact Site 5 is a hammerhead turnaround (as in Version 1), but the new maps seem
to show a cul-de-sac. This also seems to imply that there will not be an extension to Ross Rd. Please clarify and
provide a copy of the comments from the City of Durham that required these increases in buffer impacts. A
hammerhead turnaround was initially proposed to minimize impacts. The City required a cul-de-sac due to
the distance between the temporary end of Lynn Road and the closest intersection. An email where we
coordinated this with the reviewer is attached. A future extension of Lynn Road is still planned (by the City,
not the project), and the project is reserving right-of-way for the future extension.
3) Please provide more details on the large increase in buffer impacts for Impact 6a, specifically on avoidance and
minimization, including alternate configurations of the SCM. This increase was due to design modifications
needed to meet stormwater requirements during permitting. These included:
a. 1YR-24HR peak attenuation requirements
b. Larger surface area to measure WQv at bottom of pond rather than top of bank
c. Larger surface area to provide a slope on the outfall pipe. We originally showed the outfall pipe flat to
further minimize velocity into the buffer. The City requested a slope on the outfall pipe, which is at a
set elevation to outfall into the stream. Adding a slope to the outfall pipe raised the bottom of the
pond and berm. Raising the berm created additional grading that encroached on the SCM surface
area, requiring the SCM to be reconfigured.
Thanks,

Hey Colleen,
I wanted to check in on this because I wasn't sure if it is a 60 day or 90 day review on your end!
