Subject: Preconstruction Notification and request for 404 and 401 permits for the construction of
the EEP Full Delivery Project called "Blockhouse Creek Stream Restoration Project".
Blockhouse Cree, Broad River Basin - CU# 03050105, Polk County, NC.
Dear Ms. Karoly:
Enclosed with this letter are five (5) copies of the Pre-Construction Notification, EEP approved
restoration plan, project plan set, EEP approval letter and an electronic version of these materials.
I have also attached to the PCN a check for $475.00 to cover the application fee. Baker has
signed an MOU with DWQ for electronic submission of applications and we have attempted to
follow DWQ's guidance with this. In addition I have sent one additional copy directly to Kevin
Barnett to save your office the time and expense of forwarding it to him. We have also submitted
this information to the U.S. Army Corps of Engineers, N.C. Wildlife Resources Commission and
N.C. Land Quality Section for their review. We are providing this information for your
department's consideration and comments relative to 401 permitting.
Blockhouse Creek is not designated as trout water by the Division of Water Quality and does not
appear to provide Coldwater habitat or support trout. We believe that the results of this project
will improve habitat at this site for native aquatic and terrestrial species. We are trying to move
this project to construction by the first of the year and your timely review will be appreciated.
Thank you for your consideration of this request. If you have any questions, please contact me as
soon as possible at 828-350-1408 ext. 2002 or 828-734-7445.
Sincerely,

9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: West of the I-26 crossin~gLBlockhouse Creek and the first
unnamed tributary flow through the FENCE equestrian show area. Adiacent land use is
mowed grass and equestrian arenas Riparian buffers in this section are minimal generally
var~ng between 5 and 20 feet in width Vegetation consists of native and exotic invasive
species The channel has been straightened is incised and has a lot of sand on the bed. East
of the I 26 crossing land use surrounding Blockhouse Creek is more forested with large areas
of mowed _grass maintained for cross country equestrian events and nature programs and a
small fond The two tributaries West of I-26 have forested buffers with UT2 having an early
successional forest and UT3 having a mature forest Riparian buffers in this section are
generally 10 feet to over 100 feet in width Vegetation consists of native trees and shrubs
with some invasives such as multi-flora rose privet and kudzu. The upper channel m this
reach is extremes incised downstream to a walking bridge where it becomes less incised and
has overly_ sinuous meanders that are causing extreme erosion and undercutting trees that are
fallin in the stream A low-head dam will also be removed from this lower reach.
10. Describe the overall project in detail, including the type of equipment to be used:
Restoration and enhancement activities are proposed for this site and include establishing a
conservation easement along Blockhouse Creek and Unnamed Tributaries (UT) 1, 2 and 3,
~.;rading floodplain benches in areas where the channel can no longer access its floodplain,
installing in stream boulder and log structures to protect unstable and newly constructed
stream banks Installation of vegetated geolifts bank and bed grading in existing channel
offline construction of new channel bank matting_and planting and floodplain planting. This
work will rewire the use of track-hoes with hXdraulic thumbs a bulldozer for grading and
dum trucks to move materials.
11. Explain the purpose of the proposed work: The ~ur~pose of this project is to establish a
ermanent conservation easement on Blockhouse Creek and three unnamed tributaries within
the project area and to stabilize the existing unstable stream system by restoring and
enhancing the channels to accomplish a more natural and stable dimension, pattern, and
profile within project constraints Beyond establishing~a more stable channel, the purpose is
to improve fish and wildlife habitat that the channel provides.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Impacts from this work will be
minimized whenever possible However in order to accomplish the restoration effort,
impacts may be realized from temporarilX increased turbidity when boulders or woody
materials are installed from temporary loss of vegetation and from stream bed and bank
grading Much of the work on Blockhouse Creek and UT 1 will involve the construction of
new channel outside of the existing channel but connected to parts of the existing channel.
This work will be done "in the dry" as much as possible minimizing impacts. Stream flow
will not be directed into this new channel until all stabilization measures have been
completed Other work on Blockhouse Creek and UT 1 will involve grading and structure
installation inside the existinu channel In this case water will be pumped around the work
area and all stabilization will be completed before flow is released back into the channel. For
most of the length of UT 2 new channel will be constructed in a newly excavated floodplain
in the vicinity_ of the existing channel A dump-around operation will be implemented in
these areas Temporary check dams will be installed at the downstream end of all reaches to
capture anX sediment lost during construction activities Anticipated long-term impacts of
the project include an increase in stream bank stability increased heterogeneity of instream
habitat and improved vegetative cover UT3 will be preserved
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It maybe useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and 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. The nature of stream
enhancement and restoration work requires that the work be done as described. To minimize
potential impacts we will be disturbing one that amount of stream bank that can be >;raded,
seeded and matted by the end of the day To minimize temporary impacts caused durin;; in-
stream channel construction a temporary barrier will be set in place above the construction area
and water pooled above this barrier will be pumped around the area. The pump and barrier will
be removed when the area is stabilized All graded ground surfaces will be seeded with
temporary and permanent seed mulched and matted to prevent erosion. All staging areas and
soil stockpile areas will be separated from flowing water by silt fencing. See the sediment and
erosion control sheets 29-33 in the~lan set
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.
USAGE - 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 project, a copy of the mitigation plan must be attached in order
for USAGE 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

GENERAL NOTI~JS AND CONSTRUCTION SEQUENCE
Constructionshall be performed in general accordance with the following:
1. The property encompassing this stream restoration project belongs to the Foothills Nature and Equestrian
Center (F.E.N.C.E.). This property and its facilities are available to the public for use on a daily basis.
Extreme caution must be taken to protect the general public using these facilities.
2. Construction activities will likely be under public scrutiny and therefore should be performed with the
utmost care to minimize unnecessary ground disturbances and tree removal and protect water quality.
3. All hiking trails disturbed to accommodate construction activities shall be repaired and re-opened as work
is completed. Four wooden foot bridges are located along the project reach and must be protected when
work occurs around them.
4. Equipment and materials shall be mobilized to the site.
5. Utility locations shown on these plans are approximate. The Contractor shall have all underground utilities
within the project limits located and marked prior to beginning construction.
6. Access to work areas upstream of I-26 shall be from Hunting Country Road onto F.E.N.C.E. property
through their normal traffic entrance ("Main Gate"). Trucks and equipment shall use the facility's roads to
access the project reach. Where the roads are not adjacent to the stream, centralized stream accesses shall
be used as shown in the plans.
7. Access to work areas downstream of I-26 shall be from Hunting Country Road onto F.E.N.C.E. property
through their main entrance (marked with a F.E.N.C.E, sign). A parking lot is located to the right
immediately after taking this entrance. At the back of this parking lot is a gated entrance to the pasture
from which construction access will be made, as shown in the plans.
8. A gravel "construction entrance" that consists of class A stone, at least 50 feet in length, shall be
incorporated into every access point that connects to a public road.
9. Temporary and permanent stream crossings and temporary check dams shall be installed as shown in the
plans. Temporary check dams shall be removed when grading work upstream has-been completed. The
low-head dam just downstream of the I-26 culvert shall serve as a check dam, existing sediment should be
removed from the pool above this dam prior to the beginning of construction and the dam shall not be
removed until all upstream grading work has been completed.
10. Construction shall proceed upstream to downstream. Grading of bankfull benches within a work area shall
be done before new channels are graded.
11. Temporary sand bag coffer dams shall be installed upstream of each work area and flow in the work reach
shall be diverted by pumping and piping around the work area. The length of each diversion shall be
approximately 300 to 500 linear feet. Pumping will be done when work is required in a channel where the
stream is flowing.
12. The limited clearing and grubbing required within the grading limits shall be performed so as to limit
sediment migration off-site. Logs and root wads from trees larger than 10 inches in diameter shall be
stockpiled for use as in-stream structures. Salvageable native vegetation (black willow, tag alder, silky
dogwood,. etc.) shall be harvested for transplanting or for cutting and live-staking materials.
13. The new channel sections shall be stabilized with in-stream structures, erosion control matting, seed, and
transplants before turning water into these sections. Compacted soil channel plugs shall be installed in
areas where the new channel diverges from the original channel, and the original, abandoned channel
sections will be backfilled.
14. Dewatering of off-line channel sections is expected to be minor. Any turbid water pumped during
dewatering operations in the off-line sections shall be diverted through a sediment filter before being
discharged into the downstream reach.
15. Earthwork shall be staged such that no more channel will be disturbed than can be stabilized by the end of
the work day or before tlow is diverted into a new channel segment.
16. Excess soil materials shall be stockpiled in designated staging and stockpile areas, with silt fence installed
on the stream side(s) of the base of the stockpiles and maintained when sediment has accumulated above
one third of the height of the silt fence and/or the silt fence has failed. Excess soil shall be hauled outside
the conservation easement before demobilization.
17. The flow diversions and temporary stream crossings shall be removed when no longer needed and the
banks in these areas stabilized with seeding and matting.
18. Bank and floodplain vegetation, including brush materials and live stakes, shall be installed during the
dormant season, November to April
