Re: PCN Submittal for Mills River Town Park Fishing Platform Site Bank Stabilization
Dear David,
The NC Wildlife Resources Commission completed construction of a Universally Accessible fishing pier at the
Mills River town center recreation park & greenway in March of 2015. Since its completion, there have been
numerous flood events on Mills River. There has been notable bank erosion at several locations along the river
frontage of the park site including a section on the right bank that coincides with the fishing platform structure.
The scour and erosion have exposed the concrete slab footing of the pier structure. I met with staff from the Town
of Mills River to investigate the condition of the fishing platform structure and make recommendations for repairs
and improvements to stabilize the erosion. Further flooding and scour threaten the integrity and safety of this
structure unless work is done to stabilize the eroding bank at this location.
After a performing a topo survey of the area in May of 2020, I prepared a plan to install a boulder/rock revetment
along the toe of the right bank and across the exposed front of the platform foundation. This work combined with
bank shaping and stabilization should help to protect the structure and prevent further erosion and sedimentation.
The intent is to have this work done by the regional NCWRC construction crew under my supervision.
I have been given agent authorization by the Town of Mills River to obtain any necessary permits, and I will work
with Tom to monitor construction. As we discussed earlier, a written notification for approval to perform this work
under NWP-13 will be required. I have read through the conditions of the corresponding 401 General Water Quality
Certification 4134, and this work will not require a written 401 certification.
The PCN for this project is being submitted to USACE electronically. The package includes the permit drawing set
along with supporting documentation and existing condition photos.
Please contact me if you have any questions or require any additional information.

4a. Describe the existing conditions on the site and the general land use in the vicinityof the project at the time of this application:*
The site is located on a portion of the Town of Mills river municipal center that is maintained as a public park and greenway path along Mills River. The parcel fronts the right bank of
Mills River. Surrounding properties are agricultural or commercial.
In 2015, the NC Wildlife Resources Commission built a universally accessible fishing platform and accessible route connected to the greenway path at the western end of the parcel.
The fishing platform shares a small parking area with a canoe/kayak launch that was built by the town.
Flooding over the past several years has caused bank scour and erosion at several points along the river frontage. The impacted areas include a section of the right bank beginning
upstream and ending downstream of the fishing platform site.

4h. Explain the purpose of the proposed project:*
Repeated flood events on Mills River have resulted in bank scour and erosion at a number of locations. One section of bank eroding river bank includes the site where NCWRC built an
accessible fishing platform in 2015. This platform was built on a monolithic reinforced concrete footing that was cast in an excavation of the right bank behind and above the estimated
ordinary high water level. Since then, the right bank has eroded from a point 50' upstream of the platform foundation to about 20' downstream. The scour has cut the bank back from 5
to 10 feet from its location at the time of the platforms construction. As a result, the front edge of the slab footing was exposed and undermined. This has progressed to a point where
measures must be taken to shore up the exposed footing and prevent further scour to preserve the structure and the safety of the anglers and visitors who use it.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The planned project involves construction of a boulder revetment that will be installed along the length of this eroded section. The revetment will run across the front edge of the
exposed fishing platform foundation at approximately the same location as the right bank was in 2015. The top of the revetment will be at or near the level of the top of the footing slab
and will result in low bench features adjacent to the upstream and downstream edges of the footing to points where they tie to the existing bank. The river bank above the revetment
and bench features will be sloped back and stabilized with coir matting and vegetation.
A large excavator with thumb will be used to perform grading, excavation and construct the revetment. A smaller mini -excavator and skid steer will be used to shuttle materials as
needed. The front edge of the footing cannot be reached from the top of bank by the excavator without risk of damaging the platform structure. To facilitate installation of the revetment
across the front edge of the footing, a temporary stone pad will be constructed with riprap. Once this section of revetment is completed, the riprap pad will be removed, and the
reclaimed stone will be used as backfill for the remaining sections of revetment. A rowof Jersey barriers will be set in the river upstream of the work area to deflect flow during
construction and removal of the temporary pad.

E. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
The proposed in -stream work has been designed to restore and stabilize the right bank to its location and condition prior to the flood damage that has
occurred since 2015. Construction of a boulder/rock revetment along the toe of bank vdll be needed to protect the fishing platform foundation given
the erodible soils of the bank and recurring high flow events. Bank sloping, matting and vegetation will reduce bank stress without further hard armor.
Inclusion of rock steps down to the constructed low bench will minimize erosion from continued foot traffic.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Excavation and revetment construction work will be done by equipment staged above top of bank where possible. To reach the area immediately in
front of the fishing platform, it will be necessary to construct a temporary pad in the river bed out of stone. For this, a row of Jersey barriers will be set
upstream to deflect river flow and minimize sediment transport. The temporary pad will be removed as other sections of the revetment are installed,
and the reclaimed stone will be used for backfill. Temporary sediment fence will be installed between any stockpile areas and top of the river bank and
at the base of the equipment access slope (at end of work day) until the access pad can be removed. Other areas where bank shaping is done will be
seeded & matted by the end of the same work day if possible. NCWRC biologists will survey the proposed construction area for hellbender and mussel
species before work begins. No large trees will be removed.

PROJECT DESCRIPTION
CONSTRUCTION SEQUENCE
THE PURPOSE OF THIS PROJECT IS TO STABILIZE A SECTION OF THE RIGHT BANK OF MILLS RIVER AT THE SITE OF
A UNIVERSALLY ACCESSIBLE FISHING PLATFORM AT THE TOWN OF MILLS RIVER PARK COMPLEX. THIS PLATFORM WAS
BUILT BY NCWRC IN MARCH OF 2015. FREQUENT AND HEAVY FLOOD EVENTS HAVE OCCURRED ON SEVERAL
OCCASIONS SINCE THE PLATFORM WAS BUILT. THESE FLOODS HAVE ERODED THE RIVER BANK STARTING UPSTREAM
OF THE PLATFORM SITE, AND SCOUR HAS UNDERMINED THE CONCRETE SLAB FOUNDATION OF THE STRUCTURE. THE
FRONT EDGE OF THIS FOOTING IS EXPOSED. FURTHER SCOUR RESULTING FROM FUTURE HIGH WATER EVENTS
THREATEN THE INTEGRITY AND SAFETY OF THIS STRUCTURE.
A NCWRC CONSTRUCTION CREW WILL WORK TO IMPLEMENT THE MEASURES DESCRIBED IN THIS PLAN SET. THE
OBJECTIVE BEING TO STABILIZE THE RIVER BANK IMMEDIATELY UPSTREAM AND DOWNSTREAM OF THE PLATFORM
STRUCTURE AND TO PREVENT FURTHER SCOUR AND UNDERMINING OF ITS FOUNDATION. THESE MEASURES INCLUDE
CONSTRUCTION OF A BOULDER REVETMENT THAT WILL TIE INTO THE RIGHT BANK AT ITS UPSTREAM AND DOWNSTREAM
END AND WILL RUN ACROSS THE FRONT EDGE OF THE EXPOSED CONCRETE FOOTING. THE TOP OF THE BOULDER
REVETMENT AND STONE BACKFILL WILL BE AT OR NEAR THE TOP OF THE CONCRETE SLAB FOOTING. FOR EQUIPMENT
TO BE ABLE TO REACH ALONG THE FRONT EDGE OF THE PLATFORM, IT WILL BE NECESSARY TO BUILD A
TEMPORARY PAD OF CLASS-B RIPRAP IN THE RIVER IMMEDIATELY UPSTREAM OF THE STRUCTURE. JERSEY BARRIERS
WILL FIRST BE SET UPSTREAM OF THE AREA FOR THE TEMPORARY PAD TO DEFLECT RIVER FLOW AND MINIMIZE
DISTURBANCE AND SEDIMENTATION AT THE WORK AREA. THE RIGHT BANK APPROACH TO THE CONSTRUCTION PAD
WILL BE GRADED AT 2H:1V, AND WILL TRANSITION TO TIE TO THE EXISTING BANK SLOPES AT THE UPSTREAM AND
DOWNSTREAM ENDS OF THE REVETMENT. WASHED STONE WILL BE USED AS FILL BEHIND THE REVETMENT AT THE
PIER FOUNDATION. THIS STONE WILL BE RAKED BENEATH THE UNDERMINED FOOTING AND PACKED AS EACH COURSE
OF THE BOULDER REVETMENT IS ADDED. ONCE THE SECTION OF REVETMENT IMMEDIATELY BEFORE THE PLATFORM IS
COMPLETED, THE TEMPORARY WILL BE REMOVED. RECLAIMED RIPRAP FROM THE PAD WILL BE USED TO BACKFILL
THE REMAINING SECTIONS OF REVETMENT TO CREATE LOW BENCHES ON EACH SIDE OF THE PLATFORM. THERE HAS
BEEN A HISTORY OF ANGLERS CLIMBING DOWN THE BANK ADJACENT TO THE PLATFORM TO REACH THE RIVER. TO
MINIMIZE FURTHER EROSION FROM THIS TYPE OF ACTIVITY, FLAT ROCK WILL BE USED TO INSTALL A SET OF
PRIMITIVE ROCK STEPS FROM THE TOP OF BANK DOWN TO THE LOW BENCH. ALL RESHAPED BANKS WILL BE
SEEDED, MULCHED AND MATTED WITH COIR MATTING. LIVE STAKES WILL SUBSEQUENTLY BE PLANTED DURING THEIR
DORMANT SEASON. ANY EXISTING FACILITIES THAT MUST BE REMOVED FOR CONSTRUCTION ACCESS WILL BE
REPLACED. ALL DISTURBED AREAS WILL BE SEEDED AND MULCHED ONCE CONSTRUCTION IS COMPLETED. ANY
TEMPORARY EROSION CONTROL MEASURES WILL BE REMOVED ONCE THE SITE IS STABILIZED.
PROJECT SCHEDULE
WORK IS PLANNED TO BEGIN IN SEPTEMBER 2020, AND SHOULD BE COMPLETED WITHIN TWO WEEKS OF START
THIS SCHEDULE MAY CHANGE BASED ON RIVER LEVEL AND WEATHER CONDITIONS. CONSTRUCTION SHOULD BE
PERFORMED DURING PERIODS OF LOW RIVER LEVELS.
GENERAL NOTES

Subject: Re: [EXTERNAL] Bank Stabilization of Erosion at NCWRC Fishing Piers (Lansing & Mills River)
Mills River Fishine Pier: Henderson Co: FWS Loe No 20-319
I understand that design plans may be modified from what was provided in your last correspondence to
show a continuous rock sill. Please send along final design plans when they are available and I will get
input from our recovery biologists. This reach of the Mills River supports the federally endangered
Appalachian elktoe and the proposed project may affect this species. The proposed impact area should
be surveyed for this species prior to instream construction. I think negative survey results would
discount the likelihood of direct impacts to this species, and potential indirect impacts to this species
would be addressed in the USACE's regional and general NWP conditions to prevent erosion and
sedimentation. Therefore, I think negative survey results would support a "may affect, not likely to
adversely affect" determination from the appropriate action agency.
Hellbender, slippershell, and creeper mussels may also occur within the proposed impact area. Same as
above, no ESA protections for these species and we suggest coordination with USFWS and NCWRC
biologists to move these animals out of harm's way prior to construction activities. And again, we will
defer to WRC biologists on the efficacy/feasibility of installing additional hellbender shelter rock.
