APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS
Town of Chapel Hill
306 N. Columbia Street
Chapel Hill, NC 27516-2124
Dear Sir.
You have our approval to place fill material in 0.60 acres of wetlands or waters for the purpose of
developing a recreational facility and road at Northern Community Park in Chapel Hill, as you described in
your application dated 27 September 1996. After reviewing your application, we have decided that this fill is
covered by General Water Quality Certification Numbers 3022, 2671 and 2733. These certifications allow
you to use Nationwide Permit Numbers 12, 26 and 14 when they are issued by the Corps of Engineers.
This approval is only valid for the purpose and design that you described in your application except as
modified below. If you change your project, you must notify us and you may be required to send us a new
application. For this approval to be valid, you must follow the conditions listed in the attached certification
and any additional conditions listed below. Stormwater management must be conducted as described in your
application. A conservation easement or deed restriction shall be added to remaining wetlands to prevent
future fill. The road culvert shall be placed below the bed of the stream so as not to prevent aquatic life
management. In addition, you should get any other federal, state or local permits before you go ahead with
your project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-
Discharge and Water Supply Watershed regulations.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing.
You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written
petition which conforms to Chapter 150B of the North Carolina General Statutes to the Office of
Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. This certification and its conditions
are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water
Act. If you have any questions, please telephone John Dorney at 919-733-1786.
Sincerely,

Town of Chapel Hill
Soccer fields
Permit No. 00947
On March 7, 1996, I conducted a preliminary site visit. I rated
the wetland at the proposed soccer fields and discussed storm water
concerns (see attached letter) during this site visit.
To date I have not visited the location of the proposed road
crossing, but they adequately addressed this issue in their
application. The RRO recommends issuance.
Note: the town of Chapel Hill is planing to route storm water from
a* near by subdivision through a 400 foot grassed water way at a 1%
slope. This water once went through a narrow portion of the
wetlands proposed to be impacted by the soccer field. In addition
they are also proposing to build three areas that they call
constructed wetlands (totaling 0.36 acres). They plan to plant
native wetland plants and'route stormwater in these areas as well.
They will also manage storm water through detention basins (dry).
please call if you have any questions

Dear Mr. l.oveman:
Comment-
and wetland
n community Park
On March ?; 199, I conducted a site v;sit at the proposed Northern
Clotrmanity Park in Chapel Hill. This v+sit was. at your request in
order to provide you (Chapel Hill) information regarding the value
of the subject wetlands that are being considered for impact and
the respective influences this project may represent to water
quality.
Sfnce this proposed activity in below current DEM wetland acreage
*.hrpsholds no wetland permit application is required by DEM (a 4 l
Water Quality Certification is required when 0.33 acres or more of
wetlands are being proposed to be filled). Further, the comments
offered and the RRO's intention for its use is to provide Chapel
Hill assistance in their apparent proactive resourc6 decision
making process. Accordingly, the comments offered do not represent
a permit, regulatory conditions, or contain an agenda regarding
Chapel Hill's policy decision methodology with respect to this
wetland fill.
General Information:
The subject wetlands were rated using the "Guidance for Rating the
Values of Wetlands in North Ca.rGline". This ,ranting system 19 a
tool for making decisions regarding 401 wdtar Quality
Certifications by the Divisipn of Environmental. Man6CJ&Ment. As the
the emphasizes this rating system is for guidance and dohs not
dictate the Division's 401 (wetland certification) deci8iOns.
This rating system is designed to evaluate the vall:eg cif `'"R
wetland with respect to the protection vi water-quality. That .is,
this system rates the value of the wetland based on "ability" and
"opportunity". For example# a disturbed area adjacent to a wetland

increases the value of the wetland (as compared to forested
drainage basin) to protect water quality through pollutant removal.
The wetland values that are considered include 1) water storage, 2)
bank/shoreline stabilization, 3) pollutant removal, A) wildlife
habitat, S) aquatic life value, and 6) recreation/educatlon.
Site description:
Thy P"1"-;-,,.+ :.,et land is a small (approximately 0.25 acral
i„termittunt dra=in. it emanates from an adjacent subdivision
(Rainbow Ele! g;;ts? y where it is narrow. The wetland continues down
slope and broadens somewhat to its confluence with Booker Creek
(Class S NSW, Cape Fear River Basin).
Wetland water Quality Issues
it was noted that this wetland receives stormwater from the up
slope subdivision, where stormwater flows through the wstland and
is spread out to the a creek bottom of Bookar Crook. This allows
for pollutant removal and dissipates the velocity of storm event
flow. However, the wetland offers a limited amount water storage.
The wetland rating was 52. This represents a moderate score.
(Note: FYI - I would consider a score of 25 as low and 70 a high
score)
Discussion:
Does this wetland have value? Yes...
However, except for amall ra's zven'ts (though aepecialli important
from a water, duality perspective) this wetland has limited
"abi l i.tv" for nutrient remova?1 considering that large surface area
draining into this small wetland. Therefore it is important to
understand that this wetland is not the "best thing around".
A possihle consideration: If Chapel Hill chooses to put a sacCrr
field in this location stormwater could be diverted into a
permanent- (w€?t retention) stormwater pond and then spread or sheet
flowed into a maintained grassea water-way between the two soccer
fields- xn many respects this may vitimately accomplish at greater
protection to surface writer quality than simply avoiding the
wetland. (Due to the treatment of stormwater from both soccer
fields and the adjacent subdivision).
Issuelt : -.
During the site visit i discussed several possible a:lternativ0s for
positioning of the soccer field. you satisfactorily explained the
Iimitations /constrai.nts of the site given the multi-resource
demands of the proposed park.
The PlAe-ement of a SA?'cer field containing a managed grassy field
1oCated adjacent to stream bottom can allow for fertilizers to

enter surface waters. Regardless of the final placement of any of
the baseball and soccer fields at the Northern Community Park, care
should be taken to insure that Rest Management Practices are in
place during routine maintenance of these fields.
Several small detention ponds were observed in the proposal foot-
print of the project. I recommend using permanent wet retention
ponds for stormwater. These structures offer significantly greater
protection of water quality. In addition, I recommend that these
ponds have a velocity dissipater and perhaps a spreader device
located at their out fall. This reduce the velocity of water and
limits scour. (Although.I have not discussed this project with
him, Mr. Warren Faircloth with Orange county planning Department
at [phone] ext. 2586 may be able to provide valuable
assistance with this issue. Also, Mr. Bradley Bennet with DEM`s
Central office may also be able to provide additional information
regarding stormwater structure design specifications [phone]
ext. 525.)
I appreciate the opportunity to comment on this project. if I Can
be of further assistance please call [phone].

DATE: October 23, 1996
SUBJECI': Section 401 Certification for Town of Chapel Hill, Orange County, North Carolina.
D WQ: 960947.
Biologists with the Wildlife Resources Commission have reviewed the subject document. Our
comments are provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C. 466
et seq,).
County.- Town of Chapel Hill proposes to develop a community park on a 46-acre tract in Orange
We have no objections to the proposed project provided the certification is conditioned as
follows:
1. A minimum 100-foot forested buffer of native trees and shrubs should be maintained and/or
established adjacent to each side of Booker Creek. Maintenance of this buffer aid development
of klormwater control structures as proposed in the application should protect water quality in
Booker Creek.
2• Place steed restrictions on this property to prevent further impacts to wetlands and miti
areas witlihi this tract of land, bation
3. Require any culverts to be installed 12 inches bolow the stream bed to prevent Fragmentation of ?
aquatic habitat.
4. Require that the hydrology ofremaining wetlands be rttaintained. Suf7icient stormwater should
be routed to remaining wetlands to maintain hydrology, however, energy should be dissipated
to prevent erosion o1' wetland areas.
Thank you for the opportunity to review and comment on this Section 401 Certification. if you

NORTHERN COMMUNITY PARK
Chapel Hill, North Carolina
REASONS FOR IMPACTING WETLANDS:
1. Road Crossing:
Access to the western third of the site requires crossing wetlands. The private land
owner will not grant access over the adjacent property west of the site. Access from
the east would require crossing Booker Creek and its substantial floodplain. The
wetland proposed to be crossed is primarily alder swamp and/or swamp forest along
an unnamed intermittent stream which joins Booker Creek approximately 150 feet
below the proposed crossing.
Impact Minimization: Proposed road crossing is as perpendicular to the wetlands as
site conditions allow.
2. Fill for Soccer Field:
The Town of Chapel Hill has identified a strong need within the community for
soccer fields and ballfields and believes that it is in the best interest of the community
to provide two of each in this park. Construction of the second soccer field will
cause the loss of approximately 0.24 acres of headwater forest wetland. This
wetland is located between the Rainbow Heights housing project and Booker Creek.
It drains approximately 7.4 acres, primarily from Rainbow Heights. The stormwater
from Rainbow Heights passes through an existing detention basin above the wetland
area.
Other locations for the soccer field were considered; the only possible alternative
outside of the forested floodplain is the wooded knoll west of Rainbow Heights.
This area has the most extensive collection of mature hardwoods on the site as well as
scenic rock outcrops. The park plans propose preservation of this area for picnicking
and childrens' play in the heart of the park. The proposed arrangement of facilities
also separates the two field areas and allows for a more attractive interweaving of
play fields and woodland.
Proposed Mitigation Measures: The drainage from Rainbow Heights which currently
flows through the wetlands to be filled will be rerouted to flow through a 400 foot
long grass lined channel with a 1 % slope. The existing watercourse through the
wetlands is approximately 280 feet long.
Three constructed wetlands totalling 0.36 acres in size are proposed as part of
stormwater management measures in this project. These wetlands will be planted
with native wetland plants. Stormwater will also be managed by means of dry
bottomed detention basins and outlet control at catchbasins. These basins will
maintain a post development discharge rate which does not exceed pre-development
conditions.
Utilities and pedestrian bridge crossings:
An 8" water line and a future 4"-8" sewer line are proposed to cross Booker Creek to
provide a looped water line through the park and sewer service for the future

community center. Construction of these lines and of the pedestrian bridges will
temporarily impact a small section of Booker Creek (approximately 40') as well as
the edge of a small wetland area west of the creek. The amount of wetland
temporarily impacted will not exceed 0.01 acre.
Preservation and protection of Booker Creek and its floodplain have been important
considerations throughout the park planning process. Park facilities have been kept out of
the floodplain as much as possible while providing a balance of active and passive
recreational elements. Clearing and grading is kept to a minimum within the floodplain to
preserve the natural bottomland hardwood forest. Wetland impacts were carefully
considered by Chapel Hill's Town Council, as well as by the park designers, before it was
decided, on balance, that the benefits to the Town justified the loss of wetlands caused by
construction of the second soccer field. Mitigation by means of constructed wetlands and
other stormwater management is proposed as part of this project.
