Dear Mr. Smith:
Thank you for your help with this proposed residential subdivision. We are submitting the
additional information requested from written correspondence on September 26, 2013.
Keller Environmental consulted with Mr. James Lastinger of the Corps (COE) of
Engineer's Raleigh Regulatory Office. Additional field work was also conducted to clarify the
wetland, stream and riparian buffer impact areas.
Turtle Creek Lane (Permanent stream crossing)
Below is an eastern view of an existing stream crossing on the eastern tributary. This
location was surveyed and is shown on Plan Sheet C -5. It is immediately upstream of the
proposed Turtle Creek Lane. The dirt road will be utilized during construction then removed and
the stream restored when the permanent road is ready.

The surveyors also marked the proposed centerline (orange flag) of Turtle Creek Lane.
Below is an upstream photograph of the intermittent stream. A KE truck is visible at the top of the
photograph on the existing dirt road. Both photographs were taken on October 14, 2013.
Temporary Utility Line Crossing Impacts
Utilization of suitable soil areas on the western side of the West tributary is proposed.
These areas will be utilized for the placement of septic fields servicing Lots 14 -16. Temporary
construction impacts to the stream channel areas involve excavating a narrow trench for the 3-
inch diameter sewer line. The stream channel, bank and riparian area will be graded to original
contours upon completion and stabilized.

We are requesting for NC Division of Water Quality (DWQ) written approval under Section
404, Clean Water Act, 33 USC 1344 This will assist in compliance with Nationwide Permit
(NWP) 29 We have addressed your included written comments in the following paragraphs
1. The application states that there are impacts to 404 and isolated wetlands, but
the impact table in section C.2. of the application just has the impact to the 404
wetland listed. Please clarify the wetland impacts.
The applicant inadvertently listed wetland impacts on the original PCN Mr Lastinger
recommended replacing PCN page 4 with the one attached There is no wetland
impacts anticipated for this project
2. Figure 3 depicting the impacts of this project did not appear to show the 404
and isolated wetland areas as overlays.
Please refer to the explanation above
3. Indicate all wetland impacts including fill slopes on the impact map and clearly
label impacts.
Please refer to the explanation above.
4. Per the requirements of the Neuse Riparian Buffer Rule, you must show that this
site meets diffuse flow requirements with a level spreader - vegetated filter strip
or other BMP per Chapter 8 of the BMP Manual. This requirement applies to the
stream crossing and the three ponds.
Please refer to the attached Plan Sheets C -5 and D -2 The level spreader
supplements and Operation and Maintenance agreements are also attached
5. Depict contour lines down slope of the level spreaders to show that they have
been correctly sited per the BMP manual.
Please refer to the attached Plan Sheets C -5 and D -2 The level spreader
supplements and Operation and Maintenance agreements are also attached

6. Please provide a full -size plan sheet showing the entire site with its storm
drainage system, including any inlets, outlets and all conveyance devices.
Please show that diffuse flow requirements have been met at every proposed
outlet location.
Please refer to the attached Plan Sheets C -5 and D -2.
Mr. Frazier is fortunately under contract with a local builder to construct all of the lots and
accompanied infrastructure. The team, including the owner and buyer, would appreciate your
approval of this minimally- invasive subdivision. It would also avoid financial hardship to Mr.
Frazier due to contractual obligations of permit acquisitions.
If you should have questions or require additional clarification please feel free to contact me at

it Mr. Frazier:
August 21, 2013, the Division of Water Resources (Division) received your application requesting a 401
ter Quality Certification and Buffer Authorization from the Division for your project. The Division has
ermined that your application is incomplete and cannot be processed. The application is on -hold until the
owing information is received:
1. the application states that there are impacts to 404 and isolated wetlands, but the impact table in
section C.2. of the application just has the impact to the 404 wetland listed. Please clarify the wetland
impacts.
?. Figure 3 depicting the impacts of this project did not appear to show the 404 and isolated wetland
areas as overlays.
3. Indicate all wetland impacts including fill slopes on the impact map and clearly label impacts.
4. Per the requirements of the Neuse Riparian Buffer Rule, you must show that this site meets diffuse
flow requirements with a level spreader - vegetated filter strip or other RMP per Chapter 8 of the BMP
Manual (see http: / /portal.ncdenr.org /web /wq /ws /su /bmp- manual). This requirement applies to the
steam crossing and the three ponds.

Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenatnce record will be kept in a
log in a known set location. Any deficient BMP 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
may be 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. v
- Once a year, soil pH will be tested and time 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 operation 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
