D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
We are proposing only 2 total crossings to the entire project The final proposed crossing has been placed to minimized stream/wetland impacts

Swift Creek in addition to the Johnston County required 100' npanan buffer.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The roadway will be designed and built in accordance with NCDOT standards Proper erosion control measures will be used to prevent
sediment from leaving the site. A level spreader will be utilized to convey stormwater from the crossing to the existing creek. A BMP will be proposed
to control stormwater of the parkway in a future phase of this project

Operation and Maintenance Agreement
I will keep a maintenance record on this BMW. This maintenance 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.
- 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 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.

On -Site Determination for Applicability to the Neuse Riparian Area Protection Rules (15A NCAC 2B
.0233) - EXPRESS REVIEW PROGRAM
Dear Mr. Johnson:
On June 28, 2007, at the request of Mr. Neal Floyd, Lia Myott conducted an on -site determination to review three
stream features located on the subject property for applicability to the Neuse Buffer Rules (15A NCAC 2B .0233).
The features are labeled as "A ", `B ", and "C ", on the attached maps initialed by Lia Myott on June 28, 2007.
The Division of Water Quality (DWQ) has determined that the following:
• Feature "A" is subject to the Neuse Buffer Rule at the flag labeled "Al". Stream A is intermittent at Flag
"AI„
• Feature "B" is subject to the Neuse Buffer Rule at the flag labeled "B1 ". Stream B is intermittent at Flag
"B 1 „
• Feature "C" is subject to the Neuse Buffer Rule at the flag labeled "C 1 ". At flag C 1, a jurisdictional
wetland transitions to a perennial pond (stream has been impacted by beavers).
This on -site determination shall expire five (5) years from the date of this letter.
Landowners or affected parties that dispute a determination made by the DWQ that a surface water exists and that
it is subject to the buffer rule may request a determination by the Director. A request for a determination by the
Director shall be referred to the Director in writing c/o Cyndi Karoly, DWQ 401 Oversight/Express Review
Permitting Unit, 2321 Crabtree Blvd., Raleigh, NC 27604 -2260. You must act within 60 days of the date that _you
receive this letter. Applicants are hereby notified that the 60 -day statutory appeal time does not start until the
affected party (including downstream and adjacent landowners) is notified of this decision. This determination is
final and binding unless you ask for a hearing within 60 days.
Thi s letter only addresses the applicability to the buffer rules and does not approve any activity within the buffers.
Nor does this letter approve any activity within Waters of the United States or Waters of the State. If you have
