SUBJECT Supplement to and Revision of Application for Section 404 Nationwide
Permit 42 and Section 401 Water Quality Certification for the proposed
Endor Iron Furnace Greenway (Phase I) from Kiwams Family Park on SR 1009
(Carbonton Road) to Boone Circle (an unopened road), Sanford, Lee County,
Division 8 WBS Element 33906 1 1, TIP No E4981
$240 00 Debit from WBS element 33906 1 1
REFERENCE Application for Section 404 Nationwide Permit 42 and Section 401 Water
Quality Certification, dated March 27, 2008
This packet serves to supplement the N C Department of Transportation's (NCDOT) previously
submitted permit application for the above-referenced project Per your request made at our onsite
meeting on July 9, 2008, NCDOT investigated alternatives to the two reinforced concrete box culverts
(RCBC) proposed in our permit application (one at STA 38+05, one at STA 47+71) and compiled
information to support our preferred choice of structures After review, it was determined that an RCE,C
would still be the best alternative at both crossings Please see the enclosed copies of the fAlowilig
documents, which provide the requested information a Structural Recommendations memo, Culvert
Survey and Hydraulic Design Reports for both proposed culverts, Geotechmcal Reports for both
proposed culvert sites, a Cost Estimates memo outlining various pedestrian bridge options, and cost
estimates for the two proposed culverts
UPDATED IMPACTS TO WATERS OF THE UNITED STATES
Although we plan to proceed with the use of the two RCBCs, because of a change in the proposed
construction method, the stream impacts for the project have changed slightly since the initial
application Therefore, this packet also serves to update our jurisdictional impact calculations to reflect
the new construction method Please see the enclosed copies of the updated Pre-construction
Notification (PCN), updated Wetland Permit Impact Summary sheet, and updated Site 1 and 2 pemut
drawings showing these changes

Permanent Impacts'`'"? r
_r t
Sites" 1 'and 2
There have been no changes to the proposed permanent stream impacts associated with this project A
total of 28 linear feet of permanent perennial stream impacts will occur to UT 1 to Big Buffalo Creek at
each site, totaling 56 linear feet for the entire project These impacts area result of the placement of the
double-barreled RCBCs
Ta:mpor<<ry Impacts
0-igmal y, water was going to be redirected around the area of construction at both RCBC sites using a
temmporaryy 5-foot base diversion ditch However, according to the new construction sequence
impervious sand bag dikes will be built upstream and downstream of where each RCBC will be installed
and the area between them will be dewatered using a bypass pump The water will temporarily be
diverted into a stilling basin adjacent to the stream Once the area is dewatered and prepared, a bypass
pioe will be installed between the dikes just prior to culvert construction and use of the bypass pump w ill
be discontinued Once each culvert is complete, the dikes and bypass pipe will be removed anti the
stilling basin will be obliterated This construction method will be used at both sites
Site 1
O.-igmal,y, the construction of the RCBC (STA 38+05) would have resulted in a temporary stream
impact of 124 linear feet to UT 1 to Big Buffalo Creek However, with the use of the new construction
method, a total of 49 linear feet of temporary impacts will now occur This is a decrease of 75 linear
feet
Site 2
O -iginal y, the construction of the RCBC (STA 47+71) would have resulted in a temporary stream
impact of 132 linear feet to UT 1 to Big Buffalo Creek However, with the use of the neu construction
method, a total of 55 linear feet of temporary impacts will now occur This is a decrease of 77 linear
feet
Compensatory Mitigation
As in the initial application, no mitigation is proposed for the 56 linear feet of permanent perennial
sti earn impacts to UT 1 to Big Buffalo Creek (28 linear feet at both Site 1 and Site 2) because of the
minimal amount of impact Additionally, the stream is in a very urbanized area, has little to no bufter or
canopy, and has been impacted by sedimentation Furthermore, the stream has already been
detrimentally impacted by in-stream construction both immediately upstream (a single-barreled RC B(--)
and downstream (three 90-inch corrugated metal pipes) of the proposed impacts

explain why these design options were not feasible Also discuss how impacts were minimized once the
desired site plan was developed If applicable, discuss construction techniques to be followed during
construction to reduce impacts See previously-submitted cover letter, dated March 27, 2008
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H 0500, mitigation may be required by the NC Division of
Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands
or greater than or equal to 150 linear feet of total impacts to perennial streams
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits,
published in the Federal Register on January 15, 2002, mitigation will be required when necessary to
ensure that adverse effects to the aquatic environment are minimal Factors including size and type of
proposed impact and function and relative value of the impacted aquatic resource will be considered in
determining acceptability of appropriate and practicable mitigation as proposed Examples of mitigation
that may be appropriate and practicable include, but are not limited to reducing the size of the project,
establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as
streams, and replacing losses of aquatic resource functions and values by creating, restoring, enhancing,
or preserving similar functions and values, preferable in the same watershed
If mitigation is required for this protect, a copy of the mitigation plan must be attached in order for
USACE or DWQ to consider the application complete for processing Any application lacking a required
mitigation plan or NCEEP concurrence shall be placed on hold as incomplete An applicant may also
choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for
Stream Work in North Carolina, available at http //h2o enr state nc us/ncwetlands/strmaide html
Provide a brief description of the proposed mitigation plan The description should provide as much
information as possible, including, but not limited to site location (attach directions and/or map, if
offsite), affected stream and river basin, type and amount (acreage/lmear feet) of mitigation proposed
(restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e g , deed
restrictions, conservation easement, etc ), and a description of the current site conditions and proposed
method of construction Please attach a separate sheet if more space is needed
No mitigation is proposed for the 56 linear feet of permanent stream impacts to UT 1 to Big Buffalo
Creek (28 linear feet at both Site 1 and Site 2) because of the minimal amount of impact
Additionally, the stream is in a very urbanized area, has little to no buffer or canopy and has been
impacted by sedimentation Furthermore, the stream has already been detrimentally impacted by in-
stream construction both immediately upstream (a single-barreled RCBC) and downstream (three 90-
inch corrugated metal pipes) of NCDOT's 12=osed impacts

MEMORANDUM TO Mr James Mason
Central Environmental Specialist
FROM Carlas Sharpless, P E e 4
Assistant Regional Hydraulics Engineer
SUBJECT Structure Recommendations for the Endor Iron Furnace
Trail, E-4981
The Endor Iron Furnace Trail is a project located in Sanford, NC The proposed
alignment is approximately 1 43 Miles in length and will be constructed along power and
sewer easements adjacent to Big Buffalo Creek and its tributaries The project begins at
the Kiwams Family Park off of SR 1009 (Carbonton Rd ) and ends at Boone Circle The
trail requires three crossings of a tributary to Big Buffalo Creek (Sta 38+05, Sta 47+71,
and Sta 65+62) The NCDOT Hydraulics Unit has conducted hydraulic analysis at each
location to determine the best viable option
Bridges were considered at all of these locations It is felt that a bridge will be the best
option at Sta 65+62 However due to the path alignment within the floodplain, it is felt
that a RCBC will be the best alternate for the other 2 crossings for the following reasons
• The culvert sites are located in a FEMA regulated flood zone The culverts will
minimize fill in the floodplam and thus minimize impacts to the 100 year flood
elevation
• A bridge structure would be required to accommodate maintenance and
emergency vehicles This will result in a thick superstructure depth that will
require fill in the floodplain (i a adverse impact to 100 yr WS Elev )
• 3 sided structures on footings were considered but eliminated because the existing
rock is not considered scour resistant See attached geotechnical report
• The proposed culverts will fit the existing channel with minimum excavation or

• The proposed culvers can be buried 1' below existing stream bed
• The proposed culverts are more cost effective then bridge structures that would
accommodate emergency/maintenance vehicles See attached cost estimates
• There is a 1 @9'x 9' RCBC dust upstream beneath US 1 and 3 @ 90" CMP dust
downstream beneath Spring Ln

DATE September 30, 2008
SUBJECT Geotechmcal Reports
Culverts at Sta 47+71 and Sta 38+05
Endor Iron Furnace, E-4981
City of Sanford
Lee County
SDU File No C71004
Please find enclosed copies of geotechnical reports for the subject project for culverts at
Sta 47+71 and Sta 38+05
4
In summary, a three-sided culvert at Sta 38+05 should not be founded on the near surface
rock, due to that rock being highly susceptible to degradation A three-sided culvert at
Sta 47+71 is also prohibitive because a similar type rock is found at this location, and it is
at a depth of approximately five feet below the invert elevation
If you have any questions or if we may be of further assistance, please contact either Tim
Sherrill or Farzin Asefnia at (919) 250-4047

Geotechmcal Report - Culvert @ 38+05
LYNDo TIPPETT
SECRETARY
The possibility of using a 3-sided/bottomless culvert was considered We do not
recommend this option Rock was encountered in the test boring and is visible in the
stream channel However, the rock type is Triassic Mudstone This material exhibits high
potential for degradation and slaking We believe that this could possibly lead to
undermining of the foundation (footings) used in the bottomless culvert design
The Geotechmcal test boring data is attached

State Bridge Design Engineer -7;* f6A9( 0=
DATE August 19, 2008
SUBJECT Cost Estimates
Various Pedestrian Bridge Options
Endor Iron Furnace, E-4981
City of Sanford
Lee County
SDU File No C71004
The Endor Iron Furnace Trail for the City of Sanford requires three crossings of a
tributary to Big Buffalo Creek It has been agreed that one of those crossings (Sta 65+62)
will require a pedestrian bridge structure Discussion has occurred for the other two
stream crossings (Sta 38+05 and Sta 47+71), as to whether it is more appropriate to use
box culverts or pedestrian bridges for these crossings At an on site meeting on July 9,
2008, permitting, cost, maintenance, and other issues were discussed for both options
The NCDOT Structure Design Unit (SDU) was requested to provide cost estimates for
several possible bridge structure options for the two crossings We understand that the
required bridge span length for each of the crossings would be approximately 70 feet
The NCDOT minimum clear width for a pedestrian and bicycle bridge is 10 feet, and
AASHTO requires that pedestrian bridges be designed for a live load of 85 psf and a
vehicular load of 10,000 pounds Below are our cost estimates for bridge structure
options

Please note that these eittmated costs are for construction of the superstructures and
substructures, only They do not include any costs for any approach fill or other items
that might be necessary
We understand that you have acquired or generated your own cost estimates for the
double 8' x 7' x 24' culvert at Sta. 38+05 and the double 9' x 9' x 32' culvert at Sta
47+71
We reiterate that, based on our experience and knowledge of the construction and
maintenance costs and issues of culverts and bridges, it is our opinion that culverts are the
appropriate option for these two stream crossings
We understand that the City of Sanford will maintain these structures We feel they
should be made well aware of the maintenance issues and costs associated with the
various options
If you have any questions or if we may be of further assistance, please contact either Tim
Sherrill or Farzin Asefma at (919) 250-4047
