APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Mathisen:
Alan W. Klimek, P.E. Director
Division of Water Quality
September 26, 2006
DWQ# 06-0830
Union County
You have our approval, in accordance with the attached conditions and those listed below, to impact
3,083 linear feet (If) (203 If of perennial) of unnamed stream to South Fork Crooked Creek in order to construct
the Glendalough Subdivision in Union County, as described in your application received by the Division of
Water Quality (DWQ) on May 17, 2006. After reviewing your application, we have determined that this project
is covered by Water Quality General Certification Number 3402, which can be viewed on our web site at
http://h2o.enr.state.nc.us/ncwetlands. The General Certification allows you to use Nationwide Permit Number
39 once it is issued to you by the U.S. Army Corps of Engineers. Please note that you should get any other
federal, state or local permits before proceeding with your project, including those required by (but not limited
to) Sediment and Erosion Control, Non-Discharge, and Water Supply Watershed regulations.
The above noted Certification will expire when the associated 404 permit expires unless otherwise
specified in the General Certification. This approval is only valid for the purpose and design that you described
in your application. If you change your project, you must notify us in writing, and you may be required to send
us a new application for a new certification. If the property is sold, the new owner must be given a copy of the
Certification and approval letter; and is thereby responsible for complying with all conditions.
In addition to the requirements of the certification, you must also comply with the following conditions:
2
The stream enhancement project shall be monitored for three years following installation. The necessary
steps shall be taken by the applicant during this period to ensure the survivability of the planting and the
stability of the stream channel.
For the two parcels currently identified for commercial development (2.42 acres and 12.121 acres) and any
other site that may be proposed for commercial development or may result in the impervious area to exceed
30% within the confines of the current proposed development, a final written storm water management plan
shall be approved, in writing, by this Office prior to the construction of any permanent facilities on those sites.
The storm water facilities must be designed to treat the runoff from the entire project, unless otherwise
explicitly approved by the Division of Water Quality. Also, before any permanent building is occupied at the
site, the facilities (as approved by this Office) shall be constructed and operational, and the storm water
management plan (as approved by this Office) shall be implemented. The structural storm water practices as
approved by this Office as well as drainage patterns must be maintained in perpetuity. No changes to the
structural storm water facilities shall be made without written authorization from the Division of Water Quality.

3. This certification applies to the whole project including any parcels that are not to be developed. Any
parcel(s) that may be transferred to a different entity in the future are still subject to the conditions of this
certification.
4. Onsite mitigation is proposed for the stream impacts at the site. Approximately 500 If of stream will be
enhanced through improvement in the dimension, in-stream structures and plantings along the riparian area.
In addition, approximately 19 acres (4,468 If) along the South Fork Crooked Creek will be preserved.
5. The base flow stream channel shall be maintained (reconstructed) immediately above and below the
proposed stream crossings. This may be accomplished through the construction of flood plain benches or
similar measures. These measures must be approved, in writing, by this office prior to construction.
6. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and
waters or areas within 50 feet of all streams and ponds on the property. These mechanisms shall be put in
place within 30 days of the date of this letter or the issuance of the 404 Permit (whichever is later). A sample
deed notification format can be downloaded from the 401/Wetlands Unit web site at
http:/r'h2o.enr.state.nc.uslncwetlands.
7. All wetlands, streams, surface waters, and riparian buffers located on the project site where impacts are not
allowed shall be clearly marked (example- orange fabric fencing) prior to any land disturbing activities.
8. The planting of native vegetation and other soft stream bank stabilization techniques must be used where
practicable instead of riprap or other bank hardening methods. If riprap is necessary, it shall not be placed in
the streambed, unless approved by the DWQ.
9. Storm water discharge structures at this site shall be constructed in a manner such that the potential
receiving streams (of the discharge) will not be impacted due to sediment accumulations, scouring or erosion
of the stream banks.
10. No waste, spoils, solids, or fill of any kind shall be placed in wetlands, waters, or riparian areas beyond the
footprint of the impacts depicted in the Preconstruction Notification application. All construction activities
associated with this project shall meet, and/or exceed, those requirements specified in the most recent
version of the North Carolina Sediment and Erosion Control Manual and shall be conducted so that no
violations of state water quality standards, statutes, or rules occur.
11. Sediment and erosion control devices shall not be placed in wetlands or waters to the maximum extent
practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable,
they shall be removed and the natural grade restored within two months of the date the Division of Land
Resources has released the project.
12. Upon completion of the project, the applicant shall complete and return the enclosed "Certificate of
Completion" form to the 401 /Wetlands Unit of the NC Division of Water Quality. Please send photographs of
the upstream and downstream sides of each culvert site to document correct installation, along with the
Certificate of Completion form.
13. Continuing Compliance. The applicant (The Mathisen Company) shall conduct all activities in a manner so
as not to contravene any state water quality standard (including any requirements for compliance with section
303(d) of the Clean Water Act) and any other appropriate requirements of state and federal law. If DWQ
determines that such standards or laws are not being met (including the failure to sustain a designated or
achieved use) or that state or federal law is being violated, or that further conditions are necessary to assure
compliance, DWQ may reevaluate and modify this certification to include conditions appropriate to assure
compliance tivith such standards and requirements in accordance with 15 A NCAC 2H.0507(d). Before
codifying the certification, DWQ shall notify the applicant and the US Army Corps of Engineers, provide public
notice in accordance with 15A NCAC 2H.0503, and provide opportunity for public hearing in accordance with
15A NCAC 2H.0504. Any new or revised conditions shall be provided to the applicant in writing, shall be
provided to the United States Arm Corps of Engineers for reference in an
y any permit issued pursuant to Section
404 of the Clean Water Act, and shall also become conditions of the 404 Permit for the project.
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 that
conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714
Mail Service Center, Raleigh, N.C. 27699-6714. 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 Mr. Alan Johnson in the Mooresville Regional Office at 704-663-
1699, or Ms. Cyndi Karoly in the Central Office in Raleigh 919-733-9721.

Harvesting: Only healthy, well-branched, and disease-free
stock from species approved by the Project Manager shall be
accepted. Live growing plant material at the harvesting site
shall be handled with care to avoid bark stripping and
splitting of stems. Cuts shall be made six to hveleve inches
(611 -12") from the ground or as required by the property
owner. Cuts shall be made flat or at a slight or blunt angle
to ensure that the source sites will regenerate rapidly. Each
stake shall be cleanly trimmed and cut I" above the highest
bud.
Nursery Supplied Live Plants: The planting stock should
be grown by approved nurseries within the same
physiographic region (Piedmont) and within 200 miles of
the project site. The seed sources for the plant material
should be obtained from the Piedmont. All containers need to
be at least one gallon with a 24" minimum height.
Erosion Control Matting: Area to be planted will be lined with
North American Green C125 BN Bionet matting or approved
equivalent. Matting shall be installed according to the
manufacturers specifications. Living
Soil Bioengineering Construction Requirements:
system acceptance shall be as follows for branch rooting (in
percent) based on inspection after the first growing season
(late summer/early fall)
Living System Percent Living
Live Stakes 85%
Contractor will ensure the survival rate is maintained
for the first year following construction.
Live Stake: Live stakes shall be 1/4" to 2" in diameter, 2 to
3 feet in length, angled on the bottom and cut ]lush on the
top, with buds oriented upwards. Live stakes shall be
determined living based on the presence of new growth. All
side branches shall be cleanly trimmed so the cutting is one
single stem. Stems should be scarred near the base of the
live stake to encourage root growth.
Plant Layout : Plants shall be grouped in'naturalistic' drifts.
A drift of a single species shall consist of (5) to (11) plants.
The plants in each drift should be planted in a random
manner on 2' centers. Do not plant in unnatural looking rows.
Areas dominated by bedrock will not be planted.
See planting plan for total numbers of plants.
Riparian Buffer : Plants shall be grouped in 'naturalistic' drifts.
The plants in each drift should be planted in a random
manner on 10' centers. Do not plant in unnatural looking rows.
Areas dominated by bedrock will not be planted.
