Dear Ms. Dailey,
WK Dickson is pleased to submit a Nationwide Permit 27 Pre -Construction Notification (PCN) for
Elliot Storage Design project. The PCN being submitted is notification on behalf of the Town of
Chapel Hill Public Works Department. The purposed of the project is to create and preserve a
natural green area in a largely urbanized area of Chapel Hill that will reestablish floodplain
connectivity with the stream during smaller more frequent rain events and increase the floodplain
storage during larger events. Additional goals include reduction of streambank erosion, removal of
invasive species, and creation of passive recreational opportunities.
The proposed project is along the banks of Booker Creek and a small tributary between Eastgate
Shopping Center and South Elliott Road. Both channels enter the site from culverts systems. The
upstream reach of Booker Creek is piped beneath the Eastgate Shopping Center from north of
Franklin Street.
Approximately 2.1 acres of the floodplain adjacent to Booker Creek will be excavated 2 to 8 feet to
provide additional flood storage and reestablish connectivity between the stream and floodplain.
All excavation will occur above the ordinary high water mark for the stream. Stream banks will be
stabilized with livestakes and the riparian buffer and floodplain will be planted with native trees
and plants and a natural riparian seed mix. Invasive species will be removed throughout the
project area.
Approximately 1,500 feet of concrete greenway trail will be constructed in the project area to
provide additional pedestrian connectivity in the Ephesus Fordham district. Three pedestrian
bridges will be constructed across the streams which may All construction activities shall be
performed and maintained in full compliance with G.S. Chapter 113A Article 4 {Sediment and
Pollution Control Act of 1973}.
The attached PCN package includes PCN Form, supporting figures, and design plans. Total
existing stream is 1,485 LF. Total wetland impacts resulting from the proposed project are 0.08 acres

Supplemental Information — Elliott Storage PCN
Chapel Hill, NC
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at
the time of this application:
The project is located within the Town of Chapel Hill in a developed landscape. The site is
along the banks of Booker Creek and a small tributary between Eastgate Shopping Center and
South Elliott Road. Both channels enter the site from culverts systems. The upstream reach of
Booker Creek is piped beneath the Eastgate Shopping Center from north of Franklin Street. The
origin of the small tributary was not evaluated. The project is within the Booker Creek Urban
areas, such as the project site is located, follow the Census Bureau urban -area definition and
includes residential areas and concentrations of nonresidential urban areas, such as commercial,
industrial, and institutional land; office areas; urban streets and roads; major airports; urban
parks and recreational areas, and other land within urban -defined areas (USDA 2017).
Two existing perennial streams are located on the property. Booker Creek itself is
approximately 20 to 25 feet wide with moderately incised banks and a disturbed buffer. An
unnamed tributary to Booker Creek has been straightened and dredged immediately
downstream of a 48" pipe outfall. Invasive plant species including Chinese privet and Japanese
honeysuckle are located adjacent to the streams.
3d. Explain the purpose of the proposed project:
The purpose of the project is to create and preserve a natural green area in a largely urbanized
area of Chapel Hill that will reestablish floodplain connectivity with the stream during smaller
more frequent rain events and increase the floodplain storage during larger events. Additional
goals include reduction of streambank erosion, removal of invasive species, and creation of
passive recreational opportunities.
3e. Describe the overall project in detail, including the type of equipment to be used:
Approximately 2.1 acres of the floodplain adjacent to Booker Creek will be excavated 2 to 8 feet
to provide additional flood storage and reestablish connectivity between the stream and
floodplain. All excavation will occur above the ordinary high water mark for the stream.
Stream banks will be stabilized with livestakes and the riparian buffer and floodplain will be
planted with native trees and plants and a natural riparian seed mix. Invasive species will be
removed throughout the project area.
Approximately 1,500 feet of concrete greenway trail will be constructed in the project area to
provide additional pedestrian connectivity in the Ephesus Fordham district. Three pedestrian
bridges will be constructed across the streams which may result in temporary stream impacts.
Required footings will be installed outside of the stream banks.

Standard equipment will be used including but not limited to track hoe, back hoes, excavators,
and dump trucks. Tree protection areas will be designated and fenced off to prevent large
equipment from accessing these areas.
4. Jurisdictional Determinations
4a. Have jurisdictional wetland or stream determinations by the Corps or State been requested or
obtained for this property/project (including all prior phases) in the past?
There is an overlapping area containing wetlands on the northeastern part of the property
boundary that directly abuts the new RAM Realty residential building. The three (3) separate
wetland areas identified as W3, W4, and W5 in Figure 5 were previously identified as part of
the RAM Realty project.
WK Dickson met with staff from the Army Corps of Engineers and DEQ on April 5, 2018 to
make a preliminary site evaluation and review wetland flags for W1 and W2 as well as the
ordinary high water mark for S1 and S2
4c. W3, W4, and W5 delineated by Pilot Environmental, Inc. W1 and W2 delineated by WK Dickson.
C. Proposed Impacts Inventory
6. Buffer Impacts
6i. Comments
Buffer impacts include regrading the floodplain adjacent to the stream to lower the floodplain
and make it more accessible during the more frequent stream events. Increasing the access to
the floodplain during storm flows will reduce the shear stress on the incised stream bank. After
grading is complete the buffer will be replanted with native vegetation. During the grading
operation invasive species including Chinese privet and Japanese honeysuckle will be removed.
The post -construction buffer will have greater nutrient removal due to more frequent periods of
inundation and localized wetlands will likely be created by lowering the elevation of the
floodplain.
Wetland impacts are minimized to less than 0.1 acres to only include grading for greenway trail.
All floodplain grading will occur above the ordinary high water mark and bridge crossings are
designed to have no footings within the stream bed to avoid permanent stream impacts and
minimize temporary impacts. Floodplain grading is focused only in those areas that provide
significant flood storage benefits for upstream properties. In areas where floodplain grading
does not provide significant benefits, tree protection areas are designated and no grading will
occur.
01

Supplemental Information - Elliott Storage PCN
Chapel Hill, NC
Wetland creation is expected to occur as a result of lowering the floodplain and reconnecting
the stream to the floodplain, although the specific acreage of wetland creation is unknown at
this time.
D. Impact Justification and Mitigation
The proposed project was regraded to eliminate impacts for W2 and to minimize impacts for
the remaining wetlands.
Permanent stream impacts are avoided. Pedestrian bridges are designed to only result in
temporary impacts. All floodplain grading will occur above the ordinary high water mark.
Grading will result in lower shear forces for the existing stream. Lower shear forces as well as
planting of live stakes along the bank will stabilize the stream bank and reduce downstream
sediment.
Floodplain grading is focused only in those areas that provide significant flood storage benefits
for upstream properties. The Town surveyed trees within the project area to identify areas with
significant hardwood stands that could be saved. In areas where floodplain grading does not
provide significant benefits, tree protection areas are designated and no grading will occur. The
disturbed area will be re -planted with native vegetation. The buffer impact associated with the
greenway trail is approximately 4,250 square feet.
E. Stormwater Management and Diffuse Flow Plan
No new stormwater outfalls will be installed as part of this project. New impervious surfaces
will only include greenway trails where runoff is conveyed in a diffuse manner. Runoff from
impervious areas will be disconnected and not concentrated. The majority of the greenway
drains to vegetated areas in excess of 40 feet in length, which would results in 40% (D soils) of
the runoff from impervious areas being treated through evapotranspiration and infiltration per
the DEQ Stormwater Control Measure Credit Document.

Event Code: 04EN2000-2018-E-02719
Project Name: Elliott Storage
Subject: Updated list of threatened and endangered species that may occur in your proposed
project location, and/or may be affected by your proposed project
To Whom It May Concern:
The species list generated pursuant to the information you provided identifies threatened,
endangered, proposed and candidate species, as well as proposed and final designated critical
habitat, that may occur within the boundary of your proposed project and/or may be affected by
your proposed project. The species list fulfills the requirements of the U.S. Fish and Wildlife
Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended
(16 U.S.C. 1531 et seq.).
New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could change this list. Please feel free to
contact us if you need more current information or assistance regarding the potential impacts to
federally proposed, listed, and candidate species and federally designated and proposed critical
habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the
Act, the accuracy of this species list should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the ECOS-IPaC website at regular intervals during project planning and
implementation for updates to species lists and information. An updated list may be requested
through the ECOS-IPaC system by completing the same process used to receive the enclosed list.
Section 7 of the Act requires that all federal agencies (or their designated non-federal
representative), in consultation with the Service, insure that any action federally authorized,
funded, or carried out by such agencies is not likely to jeopardize the continued existence of any
federally -listed endangered or threatened species. A biological assessment or evaluation may be
prepared to fulfill that requirement and in determining whether additional consultation with the
Service is necessary. In addition to the federally -protected species list, information on the
species' life histories and habitats and information on completing a biological assessment or

- I A 0

evaluation and can be found on our web page at http://www.fws.gov/raleigh. Please check the
web site often for updated information or changes
If your project contains suitable habitat for any of the federally -listed species known to be
present within the county where your project occurs, the proposed action has the potential to
adversely affect those species. As such, we recommend that surveys be conducted to determine
the species' presence or absence within the project area. The use of North Carolina Natural
Heritage program data should not be substituted for actual field surveys.
If you determine that the proposed action may affect (i.e., likely to adversely affect or not likely
to adversely affect) a federally -protected species, you should notify this office with your
determination, the results of your surveys, survey methodologies, and an analysis of the effects
of the action on listed species, including consideration of direct, indirect, and cumulative effects,
before conducting any activities that might affect the species. If you determine that the proposed
action will have no effect (i.e., no beneficial or adverse, direct or indirect effect) on federally
listed species, then you are not required to contact our office for concurrence (unless an
Environmental Impact Statement is prepared). However, you should maintain a complete record
of the assessment, including steps leading to your determination of effect, the qualified personnel
conducting the assessment, habitat conditions, site photographs, and any other related articles.
Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle
Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require
development of an eagle conservation plan (http://www.fws.gov/windenergy/
eagle_guidance.html). Additionally, wind energy projects should follow the wind energy
guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and
bats.
Guidance for minimizing impacts to migratory birds for projects including communications
towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http://
www.fws.gov/migratorybirds/CurrentBirdlssues/Hazards/towers/towers.htm; http://
www.towerkill.com; and http://www.fws. og_v/migratoiybirds/CurrentBirdlssues/Hazards/towers/
comtow.html.
Not all Threatened and Endangered Species that occur in North Carolina are subject to section 7
consultation with the U.S Fish and Wildlife Service. Atlantic and shortnose sturgeon, sea
turtles,when in the water, and certain marine mammals are under purview of the National Marine
Fisheries Service. If your project occurs in marine, estuarine, or coastal river systems you should
also contact the National Marine Fisheries Service, http://www.mnfs.noaa.gov/
We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Tracking Number in
the header of this letter with any request for consultation or correspondence about your project
that you submit to our office. If you have any questions or comments, please contact John Ellis
of this office at [e-mail].

RE: Chapel Hill -Elliott Storage
Dear George Lankford:
Secretary Susi H. Hamilton
NCNHDE-4545
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information
about natural heritage resources for the project referenced above.
A query of the NCNHP database, based on the project area mapped with your request, indicates that there are
no records for rare species, important natural communities, natural areas, or conservation/managed areas
within the proposed project boundary. Please note that although there may be no documentation of natural
heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have
been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists.
In the event that rare species are found within the project area, please contact the NCNHP so that we may
update our records.
The attached 'Potential Occurrences' table summarizes rare species and natural communities that have been
documented within a one -mile radius of the property boundary. The proximity of these records suggests that
these natural heritage elements may potentially be present in the project area if suitable habitat exists and is
included for reference. Tables of natural areas and conservation/managed area within a one -mile radius of the
project area, if any, are also included in this report.
Please note that natural heritage element data are maintained for the purposes of conservation planning, project
review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions.
Information provided by the NCNHP database may not be published without prior written notification to the
NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP
data may not be redistributed without permission.
The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature
