D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Per the most recent version of the DWQ BMP manual, a bypass channel is necessary for the proposed level spreader
which will result in 1,341 ft2 of riparian buffer impacts. The width of the channel has been minimized and it has been
designed to intercept the stream at an angle.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Measures such as tree protection fencing and sediment fencing to protect existing riparian buffers and water quality
during construction activities will take place.

states that many private developments are unlikely to cause cumulative impacts, including projects such as urban in -fill,
most residential subdivisions and small commercial developments as well as agricultural and silvicultural operations. The
POD 7, The Nine project is a 10 -lot development. We anticipate that the DWQ will advise us if any additional information
is needed.

Clayton, Johnston County, NC
Dear Mr. Clark:
This letter will serve as confirmation of the buffer determination made by S&EC at the
subject property referenced by the Raleigh Regional Office as NBRRO 03 -058.
On September 4, 2002, I conducted a site visit of the features involved in the above
referenced project as identified on the attached maps. It was determined that the features shown
on the Johnston County Soil Survey and on the USGS Flowers, NC Quad map could potentially
be subject to protection under the Neuse River Basin: Nutrient Sensitive Waters Management
Strategy; Protection and Maintenance of Existing Riparian Areas, Administrative Code T15A:
02B.0233 (NCAC .0233).

Dear Ms. Flowers:
RECEIVED JAN 1 i 2OU
Reference the Department of the Army (DA) permit issued on April 22, 2010,
which authorized permanent impacts to 868 linear feet (If) of important stream, 4161f of
unimportant stream and 0.122 acre of non - riparian wetlands to construct seventeen (17)
road crossings. In addition, the permit authorized temporary impacts to 1601f of
important stream, 601f of unimportant stream and 0.005 acre of wetlands associated with
the construction of these road crossings, at the intersection of NC Hwy 42 and SRI 003,
east of Clayton, Johnston County, North Carolina
Reference is also made to the letter from Ms. Deborah Edwards of Soil and
Environmental Consultants (authorized agent) dated December 20, 2012, requesting
modification of the impacts associated with Impact Area 1, and to Phase 1 of Special
Condition "1 ". Impact area 1 is currently authorized for 1501f of permanent impacts and
201f of temporary impacts. You have requested that these impacts be reduced to 1081f of
permanent impacts and 0 If of temporary impacts. Special Condition "P' currently states
that for Phase 1 of the project, you are required to make payment to the North Carolina
Ecosystem Enhancement Program (NCEEP) in the amount necessary to perform
restoration to 150 If of stream before December 31, 2012. You have requested to modify
this condition to now require the purchase of 108 credits from the EBX Neu -Con Stream
Umbrella Mitigation Bank.
The Corps has completed the evaluation of your request and concurs with your
request for a change in impacts associated with your referenced DA permit, including the
change to plans and mitigation method and amount, as requested. These changes are
referenced in the following conditions.
Special condition "a" of your permit is hereby modified to read:
"All work authorized by this permit must be performed in strict compliance with
the attached plans, Exhibit A and Exhibit B, which are a part of this permit. These plans
reflect the original proposal, Exhibit A; and the modifications as depicted within the
modification proposal as shown in Exhibit B. Only the attached modification plans reflect
approved changes to the original plans; therefore, any additional deviations from the
original plans are not approved per this modification and any further modification to the
plans must be approved by the US Army Corps of Engineers (USACE) prior to
implementation."
Special condition "1" of your permit is hereby modified to read:
"The applicant will make phased mitigation payments to either an approved
mitigation bank or the NCEEP as listed in the table below. The cost of credits will be the
current price at the time of payment, not the current price at the time the permit was
issued. No work on any phase of the project shall begin until the payment for that phase
has been issued.

Filter Strip, Restored Riparian Buffer and Level Spreader
Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
Iog 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
WIPC,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 15 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.
