Hi Stephanie. I contacted Kelly Williams with NCDMS regarding the mitigation ratio and she provided the response
below. Does the explanation she provided address your needs? If not please let me know.
Thanks, Mark. Sr.

Mark,
DMS letters reflect impacts not mitigation ratios. The letter states that DMS agrees to accept
payment for the mitigation the permit requires which may exceed the impacts. The invoice will
reflect the credits Stephanie requires for buffer. If you are in need of a customized letter, I
think we can accommodate that, but permitting agencies have not asked for that previously.

Hi Kelly; I'm handling this project while the primary project engineer is away and apparently I didn't get
all the information on this buffer impact. Stephanie Goss informed me today that the number I sent you
does not include the 3:1 mitigation ratio so I need to bump up that number to 4,032 SF of buffer
mitigation (see her email below). I'll revise the form and resend it today.
Thanks, Mark Sr.

Mark,
Mitigation for the 1,344 square feet of Zone 1 impacts have a multiplier. So, for Zone 1 impacts it is
times 3, so mitigation needed for your project would be 4,032 square feet of mitigation credits required.
Can you please resend the statement of availability letter stating you have obtained 4,032 sf or credits.
Thanks and sorry for the confusion.

Good afternoon Stephanie; I am following up on the fee in -lieu for the buffer impacts on this project
while Tom is away from the office. Our client decided to pursue the mitigation option. We determined
that there were no private mitigation credits available for this portion of the Jordan Lake watershed and
reached out to Kelly Williams with NCDMS. She has provided the attached letter confirming DMS
acceptance for this project.
Please let me know if this satisfies what you needed and please don't hesitate to let me know if you
need additional information or if I can help in any way.

Tom,
I am currently reviewing the Elliot Storage Design project. I wanted to bring to your attention the Jordan
Lake Watershed buffer rule for Stormwater BMP's (below is a snip from the Jordan Lake Watershed
table of uses for Stormwater BMP's):
<image001.jpg>

So, you have two options:
1. the Stormwater BMP stays as is and the Town of Chapel Hill pays mitigation for the 1,344 square
feet of Zone 1 impacts from the BMP (Mitigation needed would be 4,032 square feet of
mitigation credits) provided that diffuse of discharge is provided into Zone 1'.
https://deg.nc.gov/about/divisions/water-resources/water-quality-permitting/401-buffer-
permitting-branch/nutrient
2. The Stormwater BMP impacts are removed from Zone 1, can the BMP be shifted a bit to the
East, but tree preservation is to be considered as well. (no Zone 1 impacts from the BMP) and
diffuse flow of discharge is provided into Zone 1.
Please let me know your decision and we can proceed. If you choose the mitigation route, I will need a
statement of availability letter from a mitigation bank. I have included the link above for your
convenience. Please do not hesitate to contact me if you have any questions.

Thank you for meeting with us on Monday 3/25 on the Elliott storage project. I hope the attached information
addresses your comments. We have included the following:
• Memo response to DWR comments
• Revised Figure 5 showing detailed buffer impacts
• Update PCN page 7, Section 6 for buffer impacts that corresponds to Figure 5
• Tree protection exhibit
• Revised Sheet 6 of construction plans
• Proposed SCM design
The Town and Federal Realty are requesting that the attached SCM plans for Eastgate Shopping Center be incorporated
into this 401 submittal with the goal of being constructed at the same time as the Elliott Storage project. At the origina
time of permit submittal, it was uncertain if the SCM would be permitted and designed at the same time as the Elliott
Storage project. The proposed SCM does not impact streams or wetlands. As shown in the attached Figure 5, the SCM
will impact approximately 5,500 sf of buffers. The majority of the buffer impacts occur in an area with limited wood
vegetation as shown in the aerial photography. While the SCM shown in the attached plans is a bioretention area, the
SCM will be adjusted to a constructed wetland with the same footprint based on comments from the Town. If you
require further information related to the SCM, please let me know. Thanks,
IG

Thank you very much for your comments on the Elliott Storage project. The Town is anxious to move forward. I noticed
in the comments that you would like to have a site visit. Do you think it would make sense to meet in your office prior
to the site visit to address your other comments either on the same day as the site visit or prior? I would like to get the
meetings scheduled as soon as possible to make sure we comply with the 30 day time period. Are there others we
should invite to the meetings? In April 2018 we completed a site visit with Sam Dailey, Katie Merritt, and Chonticha
McDaniel.
We have not had a response from the Corps to our PCN submittal. I reached out to Sam Dailey upon receiving the DWR
comments to check on their review progress.

DATE: March 28,'2019
RE: Elliott Storage Design
This memo is in response to. the comments received from DWR on March 7, 2019 on
the 401 Water Quality Certification submittal for the Elliott Storage Design project in
Chapel Hill. The additional'information submitted includes the following:
l ,
• Response to DWR comments
• GIS exhibit showing detailed buffer impacts
Updated Section 6 of'PCN to reflect specific buffer impacts
• Exhibit showing tree protection areas
� I r
• Updated Sheet 6 of construction plans
• Design plans for proposed SCM
The numbered responses to DWR's comments correlate with .the numbers in the letter received
from DWR on March 7, 2019 and are as follows:
1. WKD Response:, The Town of Chapel Hill is focused on developing integrative
solutions for stormwater management and utilizing limited resources for infrastructure
upgrades. The Elliott Storage project is located in a highly impervious commercial area
and is one of the few opportunities at this location for stormwater management. The
primary goal ofJhe project is to reestablish floodplain connectivity that will allow
storm flow to access the floodplain, more frequently and also lower water surface
elevations in project area. The lower water surface elevations in the project area will
reduce the tailwater of the culvert under the Eastgate Shopping,Area thereby reducing
peak water surface elevations for�the 2 -year, 10 -year, and 25 -year storms by
approximately'one foot in the Eastgate shopping center that currently floods during the
10 -year event. 'The project,will reduce the severity, frequency, and duration of flooding
in a floodprone area. The project was prioritized as the top project in the Lower J3ooker

Creek Watershed Study that evaluated the entire Booker Creek Watershed for
stormwater control opportunities.
The existing channel was classified as channelized and entrenched during the stream
assessments completed utilizing the Unified Stream Assessment Protocol and the EPA
Rapid Bioassessment Protocol. Typical bank slopes are approximately 1:1 for the reach.
Shear forces become elevated above 1 lb/sf in the lower third of the channel reach
approximately 300 feet upstream of Elliott Road. In some instances shear forces exceed
1.5 lb/sf particularly for the 25 -year storm event. The proposed improvements will
reduce shear forces in this area for the 25 -year event to approximately 0.51b/sf in the
same location.
The Town of Chapel Hill maintains approximately 17.6 miles of greenways and trails
with the goal of providing alternative transportation to residential areas and shopping
centers. The greenways promote the health and well-being of Chapel Hill citizens by
providing recreational opportunities, preserving the natural environment by providing
buffers between developed areas and open green spaces, and can provide educational
opportunities for stormwater management and preservation of natural stream
corridors. Aside from the perpendicular stream crossings, the majority of the proposed
greenway was designed to be outside of the 50 -foot buffer. As shown in the attached
figure 5, the location of the greenway is predominantly located outside of the buffer.
Total buffer impacts as a result of the greenway are 3,213 sf (1,932 Zone 1). While
pervious surfaces were considered, there is concern about the erosion and maintenance
of pervious surfaces during flood events. Runoff from the trail will be dispersed in a
diffuse manner to prevent concentrated runoff.
2. WKD response: Buffer impacts are shown in Figure 5 in a more detailed manner as
follows:
a. B1 Zone 1 floodplain grading impacts: 44,735 sf. These impacts include
excavating in the floodplain above the ordinary high water mark for the
purpose of reducing flood elevations in the upstream shopping area currently
at risk of flooding. All areas shown as B1 will be replanted and vegetated
according to the planning plan shown in the provided design plans.
b. B1 Zone 2 floodplain grading impacts: 25,075 sf. These impacts include
excavating in the floodplain above the ordinary high water mark for the
purpose of reducing flood elevations in the upstream shopping area currently
at risk of flooding. All areas shown as B1 will be replanted and vegetated
according to the planning plan shown in the provided design plans.
c. B2 Greenway Zone 1: 1,932 sf. These impacts are associated with installing the
proposed greenway. The location of the greenway was designed to minimize
buffer impacts to only those associated with the perpendicular stream
crossings.

d. B2 Greenway Zone 2:.1.281 sf. These impacts are associated with installing the
proposed greenway. The location of.the greenway was designed to minimize
buffer impacts to only those associated with the perpendicular stream
crossings.
e. B3 Retaining Wall Zone 1: 250 sf. The proposed retaining wall is installed to
provide more conveyance at the pinch point immediately upstream of Elliott
Road. The wall along the right bank is located adjacent -to a sidewalk in an
already impacted buffer.
f. B4 Stormwater Control Measure (SCM) Zone 1: 1,344-sf. The property owner is
proposing to use a portion of the project site for a stormwater control measure.
This was not included in the original permit application. At the time of permit
application it was assumed the projects would be'permitted and constructed at
different times. The property owners would like to permit and construct the
SCM at the same time as the Elliott Storage project. Design plans for the SCM
are attached. While the provided plans show the SCM as a bioretention area,
the SCM will be revised to a constructed wetland with the same footprint to the
location of the seasonal high water table. The proposed SCM does not change
the function or benefits of the Elliott Storage project. There are no stream or
wetland impacts associated with the proposed SCM. While there are Zone 1
buffer.impacts as shown the condition of the buffer at this location is sparse.
grass vegetation with minimal woody vegetation. The total proposed buffer
impacts do not change as a result of the SCM, but the use changes for a small
percentage of the overall buffer impact as shown in Figure 5.
g. B4 Stormwater Control Measure (SCM) Zone 2: 4,107 sf. See description above
h. The overlook area is located outside of the buffer.
3. WKD response: The Corps has issued" NWP 27 for this project. A copy has been sent to
DEQ.
4. WKD response: The greenway was located outside of the buffer except for bridge
crossings required for connectivity. Runoff from the greenway will sheet flow
overland_ through the storage area before entering the stream.
5. WKD response: For streams where grading occurs above the ordinary high water
mark, livestakes and temporary matting will be installed for streambank stabilization
purposes. The banks will also be' graded at a 2:1 slope as compared to the existing 1:1
slope. Three rows of livestakes will be installed on each bank. See Sheet D1 for further
stabilization details.
i
6. WKD response: The pedestrian bridges will be structurally designed to withstand the
stream flows and are designed to; withstand overtopping.
7. WKD response: The flooding in the area is a result of the approximate 6 square mile
3

watershed upstream of the project site. The watershed is largely developed. The
proposed impervious surfaces will have a negligible effect on peak flows. Furthermore
any runoff from the impervious surfaces located in the project area will be conveyed
downstream prior to the timing of the peak flow from the upstream watershed.
8. WKD response: The planting plans shown on Sheets 9, 10, 11, and D1 include 6 zones
as follows:
a. Zone A: Wetland seedings and plantings. Includes live stakes along channel
banks, bare root, and container plants. Planting densities, species type, and
seed mix is shown on Sheet D1.
b. Zone B: Wetland seedings and plantings. Includes bare root, and container
plants. Planting densities, species type, and seed mix is shown on Sheet D1.
c. Zone C: Wetland seeding only along sewer main
d. Zone D: Upland seeding and plantings. Includes bare root, and container
plants. Planting densities, species type, and seed mix is shown on Sheet D1.
e. Zone E: Upland seed mix only
f. Zone F: Lawn seeding to match existing
9. WKD response: Site visit with Stephanie Goss completed on 3/25/19.
Additional comments:
• Attached is a separate exhibit showing the tree protection areas and the location within
the buffer. The tree protection areas were added as to avoid and minimize buffer
impacts as part of the B1 floodplain grading impacts. Tree protection areas are located
to preserve large hardwood trees.
• A constructed wetland area to treat parking lot runoff will be installed in the northern
section of the property directly adjacent to the parking area. The wetland area was not
included in the previous permit submittal. See attached plans for details. The wetland
area will not impact streams or wetlands. The wetland will discharge to an existing
storm drainage conveyance system as shown in the attached plans.
