Dear Ms. Karoly:
Included with this cover letter are the required items for the resubmission of the PCN
application. On January 15~ 2008, the initial application was returned due to incomplete
Level Spreader Supplement Form. The Required Items Checklists for the level spreader
supplement forms have been included. This resubmission includes all other forms and
required documentation as a complete package as requested from previous
correspondence.
Please contact us if any further information is required.
Thank you.
Sincerely,
Neal Floyd.

USACE - 1n 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 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.

"Permittee shall execute and cause to be recorded in the County
Register of Deeds restrictive covenants acceptable to the Corps of Engineers for
the purpose of maintaining the conservation areas, as shown on the recorded
plat* (identify by title, date, and recording data), in their natural state in
perpetuity, prior to the sale or conveyance of any lots or other property within the
subdivision. The permittee shall enforce the terms of the restrictive covenants
and, prior to conveyance of the property, shall take no action on the property
described in the covenants inconsistent with the terms thereof. The permittee
shall provide a copy of the recorded restrictive covenants to the Corps of
Engineers within 15 days of recording."
* It is possible and acceptable that the plat may not be recorded at the time of the
issuance of the permit. If that is the case, delete the word "recorded" and be sure you
have a copy of a plat showing the conservation areas in the file, and identify it in the
permit condition by title and date. The plat, however, must be recorded at the time the
restrictive covenants are recorded, and prior to the sale of any lots in the subdivision.

The areas shown as conservation area on the final plat of Carriage Creek shall be
maintained in perpetuity in their natural or mitigated condition. No person or entity shall
perform any of the following activities on such conservation area:
a. Fill, grade, excavate or perform any other land disturbing activities
b. Cut, mow, burn, remove or harm any vegetation
c. Construct or place any roads, trails, walkways, buildings, mobile homes, signs,
utility poles or towers or any permanent or temporary structures.
d. Drain or otherwise disrupt or alter the hydrology or drainage ways of the
conservation area
e. Dump or store soil, trash, or other waste
f. Graze or water animals, or use for any agricultural or horticultural purpose
This covenant is intended to ensure continued compliance with the mitigation condition
of a Clean water Act authorization issued by the United States of America, US Army
Corps of Engineers, Wilmington District, and Action ID and therefore may be enforced
by the US of America. This covenant is to run with the land, and shall be binding on the
owner and all parties claiming under it.

Stormwater Statement For Carriage Creek Subdivision Phase 1
Subdivision: Carnage Creek Phase 1
Location: Located within Carriage Creek Subdivision .Phase 1 is located west of
Cleveland School Road (SR 1010) and south of Pollenta Road (SR 1330).
This site is NOT located within the Environmentally Sensitive Overlay
District.
Developer: Carriage Creek, LLC

Raleigh, NC 27607
GENERAL INFORMATION
Phase 1 contains approximately 8.53 Ac. The total subdivision's acreage is approximately
68.27 Ac.
Past uses of the property are farming and woodland. Phase 1 is bordered by a riparian
buffer to the west. One stream crossing with a subdivision roadway is encountered in this
phase. Neal Floyd Jr. & Associates is handling permitting with NCDENR for placement
of fill associated with roadway construction.
IMPERVIOUS SURFACE AREA-
Total Area Phase 1 8.53 Ac.
Total Area for Road Right of Way along Phase 1 1.02 Ac.
Residual Area for Lots 8.53 Ac. - (1.02Ac) = 7.51 Ac.
Average Acreage/Lot for 11 Lots 7.SlAc./11 Lots = .6827 Ac./Lot
= 29,740 SF/Lot
Lot Impervious Surface Area 2200 SF with a maximum impervious surface area
of 3086 SF
Lot Impervious Percentage
2200 SF/29740 SF/Lot 7.41 %
3086 SF/29740 SF/Lot 10.38% (maximum allowable impervious coverage is 12%)
Phase 1 of Carnage Creek Subdivision is single family residential. The streets will be
paved sections with shoulder and grassed swales. Surface runoff will be dissipated
wherever possible with level spreaders downstream of pipe outlets.
EXISTING DRAINAGEWAYS
A 50 ft. Buffer is placed along each side of the drainageway. Neuse River Riparian
design guides were followed for Phase I. NCDENR is presently reviewing the roadway
crossing.
DOWNSTREAM AND UPSTREAM DRAINAGEWAYS
No impact is expected from phase 1 on Steep Hill Branch as this phase is approximately
0.88% of the drainage received by Steep Hill Branch.

Re: Carriage Creek subdivision on Polenta Road -Stormwater Narrative
The proposed subdivision is Located off Polenta Road and through which passes Hill Branch which is a
riparian stream within the Neuse River Basin. According the County's GIS mapping the area does not
lie within the ESOD. The proposed 77 lot subdivision will be developed under the current zoning of
Rural Residential (AR). Domestic water supply will be obtained though a connection to the existing
County system along Polenta Road and extension of a waterline through the subdivision. The sewer
for each lot will be handled via individual convention underground septic systems located on each lot.
A street system to serve the subdivision will consist of a single roadway access onto Gleveland Road
(SR 1010) which will cross Hill Branch only once at a perpendicular angle to the stream, thereby
minimizing the impacts. The land area which makes up the subdivision consists of 69.7 acres of which
an estimated 5.17 acres is wetlands and 1.83 acres is riparian buffer according to a field survey by
Soil and Environmental Consultants conducted in November, 2005. In addition to the riparian buffer
and wetlands, 6.88 acres will be dedicated as open space, which for the most part encircles the
wetland area. A total of 13.88 acres will be preserved as open space.
The roadways will be constructed of ribbon pavement which will drain to grass-lined ditches paralleling
the roadway and released into the natural drainage area after being processed by velocity reduction
measures and in many cases quantity reduction measures. According to Johnston County's
Stormwater Management guidelines, this development is limited to 15% impervious area without land
dedication BMP program. An attached analysis concludes that the actually impervious area proposed
is just slightly under 10%°. In order to hold the impervious area below the 15% threshold each Mot will
be limited to an impervious surface area of 4309 sf.
A preliminary TN export (see attached) resulted in an overall TN export of 3.07 lbs.lac./yr, which is
below the 3.6 Ibs.lac./yr. allowed. Therefore, no nitrogen reduction BMP's are proposed at this time.
It is anticipated that in order to meet the "na increase in the 1 year runoff' criteria, stormwater
detention will be required. This wiH be accomplished through open detention basins which wilt be sited
and designed as a part of the construction plans preparation.
In summary, the quality of storrnwater runoff from the development will be enhanced through the
surface drainage handling of water in grass-lined ditches wherever possible. This will be released
using velocity reduction techniques such as level spreaders. Dry detention will be employed to reduce
the volume of runoff to that of the pre-development conditions. Streams will be protected via the
observance of undisturbed buffers on the stream.

Inspection and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BNIl' elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
- Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
- Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
- Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
- Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
maybe allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
- Once a year, the soil will be aerated if necessary.
- Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of inspection and maintenance will be kept in a known set location and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
