Dear DWQ:
Enclosed, please find five (5) copies of the 401/404 application (PCN form). A check
for the application review fee is also enclosed. This project is for 200 lienar feet of new
boulder seawall to replace the existing failed and eroded seawall at the Lee & Suzie
Terrell Residence, 451 S East Shore Drive, Lake Toxaway Estates, Lake Toxaway, North
Carolina. The new boulder seawall shall be in accordance with Sheets C-1, C-2 and C-3.
Lake Toxaway has a water quality classification of B; Tr.
All disturbed areas not to be filled or flooded will be vegetated pursuant to the
seeding schedule in the Erosion and Sediment Control Planning and Design Manual. If
you have any questions or require any additional information, please do not hesitate to
contact me at [phone] or email tealleneng Qcitcom.net.

GENERAL NOTES:
1.0 All work shall be in accordance with North Carolina State
Residential Building Code, OSHA Safety and Health Requirements, US
Army Corps of Engineers 404 permit requirements, NCDENR Division of
Water Quality 401 permit requirements, NC Sedimentation Pollution
Control Act, and all other applicable codes, ordinances, and
regulations. The Contractor shall coordinate all work with the Lake
Toxaway Operations Manager, 16801 Rosman Hwy, Lake Toxaway, NC
28747.
2.0 Contractor shall verify and establish all Elevations prior to
beginning work. Contractor shall obtain all required permits prior to
beginning work. Contractor shall locate all property boundaries prior
to beginning work. Contractor shall locate, flag and protect all
underground utilities prior to beginning work. Do not locate any part
of the work within any right—of—way, set back, encroachment,
easement, trout stream buffer zone (or other buffer zone or set
bock), unless permitted to do so. Do not allow fresh concrete to
contact lake waters.
3.0 All footers and slabs shall bear on satisfactory insitu material
having a minimum bearing capacity of 2000 psf. No portions of the
foundation shall bear of fill dirt or fill soil. Contractor shall verify
that the site has stable geotechnical conditions. Top of footings
shall be located below the frost line. Footings shall be stepped
where it is necessary to change the elevation of the top surface of
the footings or where the slope of the bottom surface of the
footings will exceed 0.1 unit vertical in ten units horizontal (1% slope)
4.0 Where suspect foundation conditions are encountered, additional
over excavation may be required. This work may include:
4.1 Dewater excavation.
4.2 Excavate suspect subgrade down to satisfactory insitu material
having a minimum bearing capacity of 2000 PSF.
4.3 Line excavation with a geotechnical fabric equal to Mirafi 50OX
4.4 Backfill excavation to the desired subgrade elevation with #57
clean stone.
4.5 Provide 6 mil poly between stone and concrete.
4.6 Construct foundation in accordance with the foundation plan
designed by others.
5.0 The Contractor shall exercise care to preserve the natural
landscape and waterways and shall conduct the work so as to
prevent any unnecessary destruction, scaring, or defacing of the
natural surroundings in the vicinity of the work. All unnecessary
destruction, scarring, damage or defacing of the natural landscape
shall be corrected at the contractor's expense.
6.0 All construction materials and debris shall be removed from the
site upon completion of the project and the area shall be graded
such that all surfaces drain naturally, blend with the natural terrain,
and are left in a condition that facilitate sown ground covers and
natural revegetation.
7.0 The Contractor's activities shall be performed by methods thal
will prevent entrance, or accidental spillage, of solid matter,
contaminants, debris, or other pollutants and wastes into streams,
flowing or dry watercourses, lakes or underground water sources.
8.0 Runoff and discharge shall be monitored to insure that no
sediment is discharged to the downstream watercourse.
9.0 TURBIDITY CONTROL. The Contractor shall not violated water
quality stream standards during the performance of this work. The
Turbidity Level in the lake waters shall not exceed 10 NTUs at any
time during performance of this work pursuant to 15A NCAC 02B.0211
(3)(k). The Contractor shall employ any and all methods necessary to
prevent a violation of the Turbidity Standards. These measures
include, but are not limited to; turbidity curtains around the work,
haybails, silt fence, stone check dams, etc. Where turbidity curtain
are necessary, curtains shall remain in place until the turbidity in the
work areas return to original background levels.
10.0 HABITAT CONSERVATION. Shallow water bottom and complex
shoreline structure, most notably fallen trees and other large woody
debris (LWD), are important spawning and foraging habitats for
various sunfish, largemouth bass, and other fishes in the lake. They
are also used by many reptiles and birds for perching, basking, and
foraging areas. These areas shall be preserved to the largest exteni
possible. Such habitat shall only be removed in areas where it
creates a hazard to watercraft navigation and only to the controlling
depth in the navigation channels.
CONDITION FOR USE OF THIS PLAN — By accepting this plan, you and
any others to whom it is distributed, agree to a strict limitation of
liability for Terry E. Allen PE, T.E. ALLEN ENGINEERING, P.C., and its
employees to an amount not to exceed the fee paid in hand.

11.0 A Trout Buffer Variance is not anticipated to be necessary.
However, if during the course of the work it is determined that more
that 10% of the trout buffer may be disturbed, the Contractor shall
prepare and submit a Variance request pursuant to 15A NCAC
048.0125. This variance shall be made to the NCDENR — Division of
Land Resources.
11.1 TROUT STREAM BUFFER REQUIREMENTS — No land disturbing
activity during periods of construction or improvements to land shall
be permitted in proximity to a lake or natural watercourse unless a
buffer zone is provided along the margin of the watercourse of
sufficient width to confine visible siltation within the twenty—five
percent (25%) of the buffer zone nearest the land disturbing
activity. Waters that have been classified as trout waters by the
Environmental Management Commission shall have an undisturbed
buffer zone 25 feet wide or of sufficient width to confine visible
siltation within the twenty—five percent (25%) of the buffer zone
nearest the land disturbing activity, whichever is greater. Provided,
however, that the Sedimentation Control Authority may approve plans
which include land disturbing activity along trout waters when the
duration of said disturbance would be temporary and the extent of
said disturbance would be minimal. All tributaries to trout streams
(named and unnamed) take on the trout classification, unless the
tributaries have another specified water quality classification.
11.1.1 The 25 foot trout buffer zone shall be measured from the top
of bank.
11.1.2 The disturbance is temporary and minimal when the
disturbance is limited to a maximum of 10% of the buffer zone within
the tract such that no more than 100 linear feet of disturbance
occurs in every 1000 feet of buffer zone. These disturbances can be
approved by the NCDENR Land Quality Regional Office staff on an
Erosion Control Plan and no variance is needed. Most of these types
of disturbances are for such activities such as bridge construction,
culvert installation, and installation of sewer and utility lines
perpendicular to the trout stream.
11.1.3 Longer lengths of the buffer zone may be disturbed with the
approval of the NCDENR Division of Land Resources Director.
