Sorry I had not gotten back up with you. Since it's above Milburnie and last surveys above there hadn't really
turned up much, I think its ok to skip surveys. However before installation, a salvage/relocation should be
conducted.

Hey there John,
I hope you are doing well. Just wanted to reach back out to see if you have an update on the questions I had regarding
T&E surveys for the Perry Creek siphon. Your response will be helpful especially as I am requesting proposals for survey
work. Thanks and let me know if you would like to discuss over the phone.
Best,
Alex

Let me think some more and talk to some folks about applying the downstream surveys to the upstream
location.

What do you mean by formal vs informal surveys?

Thanks for getting back to me so quickly. With regard to the horseshoe section, please see attached map with comment
(there is no sewer proposed in the river at the horseshoe). The siphon location is specified in the Perry Creek_Wetland
Maps 11 pdf for clarity.
With regard to the HDD question, my understanding is that there are engineering and cost impediments to utilizing
HDD. One of the major engineering obstacles is that the entry angle for HDD doesn't provide enough design distance to
clear the houses on the south side of the Neuse while tying into the existing sewer on the north side.
Thanks for also answering my question regarding species to survey for. There is suitable habitat in the vicinity of the
siphon for aquatic species, but not terrestrial. I will provide additional information on the absence of habitat for the
terrestrial species along with the PCN. My two other specific questions are:
• The City of Raleigh is funding other listed species surveys for other crossings. Can the results of downstream
surveys that the City of Raleigh is performing on other crossings be used to augment information for this
crossing? Any opportunity to reduce survey costs here would be helpful.
• Please provide clarity on the type of survey (Formal or Informal).
Thanks for the reminder on the Sturgeon. I will be in touch with NMF as well.

Alex,
I'm resending and copying the Corps.

Alex,
I just read over your email again. I had missed that it said trenchless is not an option. Can you explain why
that isn't an option?
Ultimately the Corps will be processing a permit for this project and will need to make a Sect 7 determination
re: effects of the project. My recommendation on how to proceed would be for all stream crossings, not just
the Neuse, be assessed for potential suitable habitat for listed species and species proposed for listing. If
potential suitable habitat is present, then a species survey will need to be conducted. You should also contact
NMFS re: the Atlantic sturgeon.
Please remember the same habitat assessment needs to be happening for terrestrial species too.

Alex,
Has a crossing method been selected yet? We would recommend HDD to minimize impacts.
Also can you share what is happening along that "horseshoe section?"

John,
I trust this message finds you well! As you may be aware, the City of Raleigh is working on designing a number of
stream/river crossings for sewer improvements in the North Raleigh area. One of the projects involves a crossing of the
Neuse River in the Perry Creek/US 401 area (see attached maps and iPaC results). A close-up of the crossing location is
shown on Figure 6.5 of the maps.
Based on the presumed habitat suitability of this reach of the Neuse River for the aquatic species identified in the iPaC
results as well as the lack of trenchless options for the crossing, it is anticipated that species survey(s) may be required.
My specific questions are as follows:
• If surveys are required, which species need to be surveyed for?
• The City of Raleigh is funding other listed species surveys for other crossings. Can the results of downstream
surveys that the City of Raleigh is performing on other crossings be used to augment information for this
crossing?
• Please provide clarity on the type of survey (Formal or Informal).
Thanks in advance and please let me know if you have any questions or if I can provide additional information.
