Re: Bolin Creek Greenway -Phase III
Chapel Hill, Orange County, NC
On behalf of the Town of Chapel Hill -Planning & Development -Parks & Recreation, please find attached a
complete application and supplemental information requesting written concurrence from the U.S. Army
Corps of Engineers and the N.C. Division of Water Resources (NCDWR) that the activities proposed below
may proceed under Nationwide Permits 14 and General Water Quality Certifications 4135. In addition,
written authorization from the NCDWR is requested for activities proposed to impact Jordan Watershed
Riparian Buffers.
In 2011, 2012 and 2014, a Nationwide Permit 14 Verification and Water Quality Certification Approval with
Riparian Buffer Authorization were issued for this project. Since this time, approximately 3,788 linear feet of
the original 4,118 linear feet of greenway has been constructed. There was a delay in the construction
scheduled which resulted in the 404 verification and 401 Approval expiring. This delay was a because of a
coal ash deposit was discovered on a portion of the property downstream and uphill of the work site. The
Town Manager ordered that all work on the property be stopped until the Town could evaluate the situation
and come up with a plan to determine the extent of the coal ash deposit and mitigate any coal ash related
issues. The Town has developed an action plan for building the trail and disposing of any excess soil.
Please contact me at [phone] if you have any questions or require additional information.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
It's important to point out that this proposed greenway, for a majority of the corridor (south side of Bolin Creek), follows an
existing O WASA sanitary sewer line and/or existing soil paths, In addition, this corridor is not simply previously impacted,
but is predominantly bedrock and rock and has very little pervious soil due to past sewer line construction and sewer line
maintenance.
Area 5 is where the low flow channel within the stream was relocated to the southern side of the channel under the Martin
Luther King Blvd. arch culvert, a portion of the greenway trail has been constructed under this structure. Cross -vanes
have been added to redirect the flow to the center of the new channel, one remaining cross -vane is to be constructed.
Additionally, boulders are proposed along the southwest side to protect existing footings (a previous request from
NCDOT).
Several alternatives to Using the exisflrrg culvert as an 4rrrd! rmp ssing on its north srde were explored in the Concept Plat?
phase. First, a surface crnssfng of MLK near the existing green way lsrminu+ was consklered but reJecfedd for reasons of
pedestrian safety. S` icond, a new tunnel beneati i MLK NO was considemd, but rejecled for reasons f0v0ving the cost to
relocata ut#Nos in MLK Blvd and the undesirabildy or requiring greenway Ma vBWerS to use a long, narrow tunnet. Thfrd, an
option to run the grsenwey from the existlag terminus on the north bank, through Ue existing culvert, end use a !ow -water
crossing to cross to the south bank and from Mere up a shallower embankment to Umstead [?rive and west was
consfdeted. This option was rejected because of Chapel i-irll Stormwater's strong reservations about using a low-water
crossing and because it wouinl most likely result in unaeptable rises in base flood ele vatiarrs.
Impact area #6 within the stream was omitted back in 2014, and riparian buffer impact area "Q" was previously modified
because of the following:
1) The revised alignment moves the greenway about 10' further from the creek in the area of the 42" outfall
2) The retaining wall on the Creekside, made of "Strone Strong" units, is moved 10' north with the relocated greenway.
Its maximum height ins about 4.5' above the greenway surface.
3) The transition SD box form the existing 42" outfall has been eliminated in favor of a standard junction box that
conveys the existing storm flow into a 42" culvert pipe having a 1% longitudinal slope, which daylights just above the
riprap apron.
4) The existing riprap apron remains in place but would be extended northward to work with the change.
The present alignment was developed in consultation with Town Engineering staff and Town Council members, and was
approved as a Concept Plan in May 2007 by the Chapel Hill Town Council. A copy of the Concept Plan is available here:
!. / X?dQcuWpnt1d=2102.
Furthermore, the applicant is aware of the regional conditions associated with the Nationwide Permits 14. With respect to
linear transportation crossings conditions (NWP 14 -Regional Conditions section 4.0) stream relocations will incorporate
natural channel design; this project is not being used in conjunction with a NWP 18 to create an upland area; this project
is not located within tidal waters/wetlands; and this project is not located within a designated trout watershed.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Silt fences will be used to prevent sediment wash into Bolin Creek. Erosion control fabric will be applied to graded slopes
steeper than 4:1. All graded areas will be seeded. For work in the channel, the creek will be diverted to its new channel
and the former channel dewatered before commencing grading operations.
2_ Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
❑ Yes E No
2a. Does the project require Compensatory Mitigation for There are no proposed impacts to wetlands and the
impacts to Waters of the U.S. or Waters of the State? stream will be relocated, resulting in no loss of
aquatic function, therefore compensatory mitigation
is not being proposed.

Dear Mayor Kleinschmidt:
Community: Town of Chapel Hill, NC

This responds to a request that the Department of Homeland Security's Federal Emergency Management
Agency- (FEMA) comment on the effects that a proposed project would have on the effective Flood
Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) report for your communiby in accordance
with Part 65 of the National Flood Insurance Program (NFIP) regulations. In a request dated April 23,
2010, Mr. Bill Webster, of the Town of Chapel Hill, Parks and Recreation, requested that FEMA evaluate
the effects that the proposed Chapel Hill Greenway Extension Project would have on the flood hazard
information shown on the effective FIRM and FIS report. The proposed 4,000 -foot greenway extension
will connect Umstead Park to the existing Bolin Creek greenway located immediately downstream of the
Martin Luther King Jr. Boulevard crossing. The project rill include the addition of fill, the addition of a
footbridge, replacement of an existing footbridge, and removal of an existing bridge over Bolin Creek.
Also, a pedestrian underpass will be added at the Pritchard Avenue Extension culvert crossing. The
greenway will run generally parallel to Bolin Creek. The proposed project will impact flooding along Bolin
Creek from a point approximately 220 feet downstream of Martin Luther King Jr. Boulevard to a point
approximately 500 feet downstream of Village Drive. The area of the proposed project is shown on North
Carolina FIRM numbers 3710978900J and 3710978800J, dated February 2, 2007.
All data required to complete our review of this request for a CLOMR were submitted with letters from
Mr. Webster.
To determine the changes in flood hazards that will be caused by the proposed project, we compare the
hydraulic modeling reflecting the proposed project (referred to as the proposed conditions model) to the
hydraulic modeling used to prepare the FIS (referred to as the effective model). If the effective model does
not provide enough detail to evaluate the effects of the proposed project, an existing conditions model must
be developed to provide this detail. This existing conditions model is then compared to the effective
model and the proposed conditions model to differentiate increases or decreases in flood hazards caused by
more detailed modeling from increases or decreases in flood hazards that will be caused by the proposed
project.
We reviewed the submitted data and the data used to prepare the effective FIRM and FIS report for your
community and determined that the proposed project meets the minimum floodplain management criteria
of the NFIP. The submitted existing conditions HEC -RAS hydraulic computer model, dated February- 14,
2011, was used as the base conditions model in our revietir of the'proposed conditions model for this
CLOMR request. We believe that, if the proposed project is constructed as shown on the submitted plans
entitled "Bolin Creek Greenway Phase III," dated September 28, 2010, certified September 28, 2010,
104

prepared by Lappas & Havener, PA, and the certified topographic work map entitled "Proposed Conditions
Site Map", dated March 23, 2011, certified March 24, 2011, prepared by Soil & Environmental
Consultants, PA, and the data listed below are received, a revision to the FIRM and FIS report would be
warranted.
The submitted existing conditions HEC -RAS hydraulic model used more up-to-date topographic
information and survey data than the effective model. When compared to the effective model, the existing
conditions model reflects increases and decreases in the Base (1 -percent annual chance) Flood Elevations
(BFEs) along Bolin Creek, with a maximum increase of 1.1 feet at a point approximately 980 feet
upstream of Pritchard Avenue Extension and a maximum decrease of 0.7 foot at a point approximately 580
feet upstream of Martin Luther King Jr. Boulevard.
The proposed conditions model incorporates the proposed project into the existing conditions model.
When we compared the existing conditions model to the proposed conditions model, we determined that
the proposed project will cause increases and decreases in BFEs along Bolin Creek, with a maximum
increase of 2.6 feet at a point approximately 470 feet upstream of Martin Luther King Jr. Boulevard and
maximum decrease of 2.7 feet at a point approximately 480 feet upstream of Pritchard Avenue Extension.
The updated existing conditions and proposed project will have the following impacts:
Base Flood Elevations
When compared to the effective model, the proposed conditions model reflects increases and decreases in
BFEs along Bolin Creek, with a maximum BFE increase of 4.0 feet at a point approximately 70 feet
upstream of Martin Luther King Jr. Boulevard and a maximum BFE decrease of 2.7 feet at a point
approximately 480 feet upstream of Pritchard Avenue Extension.
1 -Percent Annual Chance Floodplain
When compared to the effective data, the width of the Special Flood Hazard Area (SFHA), the area that
would be inundated by the base flood, along Bolin Creek will increase and decrease. The maximum SFHA
increase of 60 feet will occur just upstream of Martin Luther King Jr. Boulevard and a maximum SF14A
decrease of 90 feet will occur at a point approximately- 980 feet upstream of Pritchard Avenue Extension.
E6du�ay
When compared to the effective data, the width of the floodway will increase and decrease along Bolin
Creek, with a maximum increase of 50 feet at a point approximately 210 feet downstream of Pritchard
Avenue Extension and a maximum decrease of 40 feet at a point approximately 170 feet downstream of
Martin Luther King Jr. Boulevard.
Upon completion of the project, your community must submit the data listed below and request that we
make a final determination on revising the effective FIRM and FIS report.
• With this request, your community has complied with all requirements of Paragraph 65.12(a) of
the NFIP regulations. Compliance with Paragraph 65.12(b) also is necessary before FEMA can
issue a Letter of Map Revision when a community proposes to permit encroachments into the
effective regulatory floodway that will cause increases in BFE in excess of those permitted under
Paragraph 60.3 (d)(3). Please provide evidence that your community has, prior to approval of the
proposed encroachment, adopted floodplain management ordinances that incorporate the increased
BFEs and revised floodway boundary delineations to reflect post -project conditions, as stated in
Paragraph 65.12(b).

it Detailed application and certification forms, which were used in processing this request, must be
used for requesting final revisions to the maps. Therefore, when the map revision request for the
area covered by this letter is submitted, Form 1, entitled "Overview & Concurrence Form," must
be included.
+ The detailed application and certification forms listed below may be required if as -built conditions
differ from the preliminary plans. If required, please submit new forms or annotated copies of the
previously submitted forms showing the revised information.
Form 2, entitled "Riverine Hydrology & Hydraulics Form"
Form 3, entitled "Riverine Structures Form"
Hydraulic analyses, for as -built conditions, of the base flood; the 10 -percent, 2 -percent, and
0.2 -percent annual chance floods; and the regulatory floodway, together with a certified
topographic work map showing the revised floodplain and floodway boundaries, must be
submitted with Form 2.
Effective January 13, 2010, FEMA revised the fee schedule for reviewing and processing requests
for conditional and final modifications to published flood information and maps. Under this
schedule, FEMA has not changed the initial fee for processing map revision requests involving
structural measures on alluvial fans. The initial fee for this map revision request will be $5,000
and must be received before we can begin processing the request. Payment of this fee shall be
made in the form of a check or money order, made payable in U.S. funds to the National Flood
Insurance Program , or by credit card (Visa or MasterCard only-). The payment, along with the
revision application, must be forwarded to the following address:

a Evidence of notification of the property owners impacted by increases in the BFEs, SFHA widths,
and floodway widths along Bolin Creek. The property owners' written acceptance of the increases
is required for the LOMR to become effective on the date of issuance.
A copy of the public notice distributed by your community stating its intent to revise the regulatory
floodway, or a statement by your community that it has notified all affected property owners and
affected adjacent jurisdictions.
After receiving appropriate documentation to show that the project has been completed, FEMA will initiate
a revision to the FIRM and FIS report. The North Carolina Floodplain Mapping Program (NCFW) will
review all revision requests in accordance with an agreement signed with FEMA under the FEMA
Cooperating Technical Partners initiative. For more information on this initiative, we encourage you to
visit the dedicated portion of the FEMA Flood Hazard Mapping website at

http.• '' e &2wjil�!preventtfhm.`ctg main.shtm or visit the NCFMP website at
h_i rw_ ttc f oodmaRs.com. Because the BFEs would change as a result of the project, a 90 -day appeal
period would be initiated, during which community officials and interested persons may appeal the revised
BFEs based on scientific or technical data.
The basis of this CLOMR is, in whole or in part, a bridge project. NFIP regulations, as cited in
Paragraph 60.3(b)(7), require that communities assure that the flood -carrying capacity within the altered or
relocated portion of any watercourse is maintained. This provision is incorporated into your community's
existing floodplain management regulations. Consequently-, the ultimate responsibility for maintenance of
the bridges rests with your community.
This CLO}1R is based on minimum floodplain management criteria established under the NFIP, Your
community is responsible for approving all floodplain development and for ensuring all necessary permits
required by Federal or State law have been received. State, county, and community officials, based on.
knowledge of local conditions and In the interest of safety, may set higher standards for construction in the
1 -percent annual chance floodplain.. If the State, county, or community has adopted more restrictive or
comprehensive floodplain management criteria, these criteria take precedence over the minimum NFIP
criteria.
If you have any questions regarding floodplain management regulations for your community or the NFIP in
general, please contact the Consultation Coordination Officer (CCO) for your community, Information on
the CCO for your community may be obtained by calling the Director, Federal Insurance and Miti tion
Division of FEMA in Atlanta, Georgia, at [phone]. If you have any technical questions regarding
this CLONIR, plum contact the NCFMP at [phone] ext. 118, or the FEMA Map_ Information
