Colleen, just wanted to give you a heads up that since it has been over 90 days since we got
the buffer SOA from a mitigation bank they have less credits available and they are from
another bank location (see attached) I will send you another SOA from another bank for the
remaining credits needed, just wanted you to have so you could note the approval accordingly
prior to issuing.

Good afternoon, Kevin!
Great timing!
The plans and ePCN show 12,084 square feet total temporary and permanent impacts in Zone 1 for impacts 6&7 that
would require mitigation, and the SOA you provided covered the 36,252 square feet. I spoke with Sue earlier today to
refresh my memory and double check the mitigation. I just sent the approval letters to be signed by my supervisor.
i

I'm in the field on Monday and part of Tuesday, so it might be Tuesday afternoon before I get a chance to email the
letters.
Have a great weekend!

Colleen, I know you are slammed but I just got the email below from the project engineer and
felt like I needed to send it to you. It has been 50 days since we replied to the concerns you
raised back in early April and I think the only thing left for you to figure out is what if any
buffer mitigation would be required. At most I believe it would only be the Zone 1 temporary
and permanent impacts at Impact 6 & 7 on sheet 6 of the impact maps submitted with the
PCN. These impacts total 12,064 so the most the mitigation would be is 36,192 sqft. If only
Zone 1 permanent buffer impacts of 4,007 sqft require mitigation, the mitigation required
would be 12,021 sqft. I sent you a SOA from a mitigation bank that would cover either of these
scenarios. Please let me know if you have questions and when you might be able to pick this
one back up. I believe you had started drafting the approval back when we did a conference
call on April 7th so maybe it will not be too time consuming to wrap up.

Subject: Richland Creek Outfall DWR Permitting
Kevin,
As you know, my firm is the design engineer for the City of Raleigh and Town of Wake Forest's Richland Creek Outfall
Renovations project in Wake Forest.
I can imagine how busy DWR must be, but it is extremely important to the Town and Raleigh Water to get the
construction of the Richland Creek Outfall moving forward. The only thing left in the way of starting that work is the
DWR approval of the buffer, stream and wetland impacts.
This has been in review for over 100 days and we have had the provisional USACE approval for over a month now.
The existing sewer lines that are to be replaced are undersized and many are over capacity.
I know this permit application must be close to being approved.
Raleigh Water and the Town or Wake Forest cannot issue a sewer extension permit or land disturbance permit until
the DWR approval is in hand. Without the sewer extension permit our contractor cannot order manholes or pipe
which are currently months out due to supply chain issues. Without the grading permit we cannot begin to install the
erosion control measures necessary to begin construction. Without the DWR approval, we are literally dead in the
water.
Please do whatever you can to get DWR to get this approval out the door.

Coleen, I contacted the project engineer and have the following responses to your questions
(see below and attached).
Summary
1. The attached sheet 6 of the impact maps, RichlandCrkOFSht6Easements.pdf, shows the
Town of Wake Forest, Harvey, and Meadows HOA properties, outlined in red, from whom
sewer easements had to be negotiated and acquired.
2. We shifted the alignment between Manholes 61 and 62 to make the crossing more
perpendicular to the creek. See the attachment RichlandCrkPrevAlignment.pdf for the
previous alignment.
3. Below is a draft explanation and attached exhibit, RichlandCrkOFSlopes.pdf, to illustrate :
1. Steep slopes — the attached plan shows in red the areas of existing slope greater than
20%. At 20% it would be impossible to keep dirt out of the creek, and highly likely that a
backhoe or excavator would wind up in the creek. The existing slopes on the south side were
just too severe. The north side route, while challenging, is not as severe and provides better
protection for the buffer, creek and wetlands.
2. Acquiring an easement from Harvey — There was no existing sewer easement through
the Harvey property. Initially Harvey refused, but then after Raleigh Water explained his
options he agreed. No other property owners were contacted. We knew Wake Forest would
cooperate with easements on their property, and felt like the easement through the HOA
property would be doable. But easements through individual properties are difficult to get
and in most instances if there is a way to avoid condemnation of a homeowners property, the
utility company to avoid it. Raleigh Water and the Town of Wake Forest are not eager to
condemn a sewer easement. Moving the line to the south side of the creek would have put the
4

clearing, construction and easement much closer to Harvey's house. Harvey would not have
granted an easement for the sewer that close to his home.
3. Boring under Coram Fields — shifting the line to the south would place the bore pit on
the east side of Corman Fields in close proximity to the sharp bend in the creek on the Harvey
property. This would make the bore under Coram Fields much more difficult to control in the
event of rain and higher stream flows during construction. The north side route provides
better protection for the creek.
Detailed Explanation
We have taken care with the design of the new proposed sewer outfall to minimize impacts
along the route. The site constraints are challenging due to Stream Feature A as well as the
large existing stormwater culvert under Coram Fields Road. There was no existing sewer
easement provided with the development of the existing neighborhood. The easement had to
be negotiated with the adjoining property owners and due to the existing street and utility
infrastructure, the available routes for the sewer outfall were extremely limited. The
proposed Sewer Outfall under Coram Fields Road is aligned parallel with the existing
culvert. The proposed Sewer Outfall's alignment best reduces the impacts to the Stream
Feature A to the east of Coram Fields Road. The Walter's Property and the shape of Stream
Feature A increase the difficulty of the proposed Sewer Outfall alignment to the west of Coram
Fields Road. The Sewer Outfall alignment crosses Stream Feature A as close to perpendicularly
as possible given the constraints. Additional manholes were used along the proposed route to
bend the alignment in order to minimize impacts and avoid placing new manholes within the
stream buffers and wetlands.
Due to the extremely steep existing slope to the west of Coram Fields Road, it is necessary to
give the contractor an alternative route to access the existing and proposed sewer easement
from the north. This alternative route uses an existing sewer easement then crosses into an
existing Town of Wake Forest Powerline Easement. The alternative route also gives the
contactor the ability to have a staging area at the end of Whistable Ave., away from any
wetlands or stream buffers. This staging area and access keep the contractor from needing
additional impacts along the existing sewer easement. The alternative route will no longer be
necessary once the sewer construction has been completed. Once construction is completed,
the contractor is to restore this disturbance back to existing conditions and stabilize with
wetland seeding_
