Re: Project Update - Post March 15, 1999 Meeting,
NPDES NCG010000 / NBRRO-99-030 / NCDWQ # 981196,
Arbor Green Subdivision, Wake County, NC
Dear Sirs:
The purpose of this letter is to notify you of activities that have taken place within the Arbor Green
Community Development since our meeting held on 3/15/99. The activities listed below were
executed in response to concerns stated within the `Notice of Violation/Notice of Enforcement'
letter dated 2/5/99 and compliance actions agreed upon during the 3/15/99 meeting. The activities
involved the removal of Sediment and Erosion Control devices from the Neuse River Basin 50-ft.
Buffers, compliance actions involving the installation of the sanitary sewer line and discussion of
potential alternatives to the "T"-intersection of Arbor Green Drive.
Sediment and Erosion Control Devices: (Please refer to the attached maps depicting the location of
the sediment control devises within the community.)
Area "A" - This area contains a temporary sediment basin as required under the original approved
Sediment and Erosion Control plan. As per the decision agreed upon during the 3/15/99 meeting,
the temporary basin within this area is still in place and will remain until the construction within
the drainage area is complete. Additional sediment control measures (including silt fencing and
seeding) have been installed in an effort to reduce any potential sediment from reaching the stream.
The basin is being maintained on a regular schedule as well as immediately after heavy rain events.
The basin will be removed and the surrounding area restored once construction within the drainage
is complete.
Area "B" - This basin was mistakenly placed within the stream buffers. In addition to the basin, a
small amount of fill material had also mistakenly been placed within the stream buffers. The basin
and fill material have been entirely removed from the stream buffers and the impacted area has
been re-vegetated. The basin is in working order and is being maintained on a regular schedule and
immediately after heavy rain events.

4/29/99
Area "C" - This area contained a rock-check dam and small temporary sediment basin as required
under the original approved Sediment and Erosion Control plan. As per the decision agreed upon
during the 3/15/99 meeting, the rock-check dam will remain in place until the construction within
the drainage area is complete. The small sediment basin has been removed and the drainage
diverted directly to the rock-check dam. The rock-check dam is in working order and is being
maintained on a regular schedule and immediately after heavy rain events. The rock-check dam
will be removed and the surrounding area restored once construction within the drainage is
complete.
Area "D" - This area contained a small temporary sediment basin as required under the original
approved Sediment and Erosion Control plan. This basin has since been removed and the impacted
area has been re-vegetated. The drainage has been diverted away from the stream and associated
buffers.
Area "E" - This area contained a small temporary sediment basin as required under the approved
original Sediment and Erosion Control plan. This basin has since been removed and the impacted
area has been re-vegetated. The drainage has been diverted away from the stream and associated
buffers.
Area "F"- This area contained a small temporary sediment basin as required under the approved
original Sediment an Erosion Control plan and a stormwater discharge pipe within the stream
buffers. The basin has since been removed and the impacted area has been re-vegetated. The
stormwater discharge pipe has been redirected and will now discharge into a small detention basin
and "sheet-flow" the stormwater prior to entering the stream buffer.
Area "G" - This area contained a small temporary sediment basin as required under the original
approved Sediment and Erosion Control plan. This basin is still in place, in working order and is
being maintained on a regular schedule and immediately after heavy rain events. The developer
and engineer are currently working with the Sediment and Erosion Control agent on a revised plan
that will keep all devices outside of the buffered area. This has proven to be somewhat challenging
given the steep topography and overall site conditions. Once a revised plan is approved and
installed, the original basin will be removed from the buffered area and the impacted area restored.
Mr. Jake Taylor, of Wake County Environmental Services (the Sediment and Erosion Control
agent for the community), has meet the developer on the site on several occasions since the 3/15/99
meeting. He has stated that the site is in compliance with the revised Sediment and Erosion
Control plan. Mr. Craig Lang, of FORTIS Homes (the developer) has been on the site almost
every day since the initial notice of violation in an effort to insure that the sediment and erosion
control devices are in working order, that no sediment is reaching the streams or wetland areas and
that the impacted stream buffers are being restored as per the decisions agreed upon during the
3/15/99 meeting.
Installation of the Sanitary Sewer Line:
Additional erosion control fencing and seeding has been installed to stabilize the sanitary sewer line
construction corridor. The sewer line has been moved further into the side-slope fill area of home
lots 3, 4 and 5 and away from the stream in an effort to reduce the amount of impact to the
associated wetlands. The sewer crossing of the secondary stream channel (for Phase 1; between
Arbor Green Community Development / S&EC, Inc. Project # 97-3071
4/29/99
home lots 5 and 14) will be done in compliance with the General Conditions of Nationwide Permit
12. Specifically, the temporary fill that had been placed within the stream channel during the site
prep work will be removed and the channel returned as close as possible to its original condition.
Alternatives Analysis to the "T"-intersection of Arbor Green Drive:
Mr. K. Robert Bell of Bass, Nixon and Kennedy (the project engineer) has prepared the attached
alternatives analysis for the "T"-intersection of Arbor Green Drive for your review.
CONCLUSION:
Please note that all the compliance actions agreed upon during the 3/15/99 meeting have or are
currently being implemented within the Arbor Green Community Development. The developer has
made every effort to insure that the project site is in compliance with the current regulations. We
believe that this revised site plan and Sediment and Erosion Control plan has minimized the
wetland impacts and Neuse River Buffer impacts to the maximum extent practicable. Please use
this information when reviewing the 401 Permit Application. Due to the actions that have taken
place since the 3/15/99 meeting, we request that you send written approval of the 401 Permit
Application.
Please feel free to call myself at 846-5900 if you have any questions, require additional information
or would like to visit the site so that someone may accompany you.
Sincerely,
Bob Zarzecki,
Biologist

Attn: Mr. Kevin Martin
REF: Arbor Greene Wetlands and Neuse River Impact
Garner, NC
Dear Kevin:
Per your request, I have investigated the different impacts of wetlands and Neuse
River Buffers regarding the Arbor Greene Drive, with and without the T-Intersection.
Please find the following attached color coded summary for Exhibits A through E:
yellow shading is for wetland impacts and orange shading for the Neuse River Buffer
Impacts.
EXHIBIT A
Exhibit A shows the existing T-Intersection which received the Town of Garner's
approval over two years ago. The area highlighted in yellow represents the Wetlands
Impacts delineation confirmed by the Corps of Engineers and permitted under 404.
EXHIBIT B
Exhibit B shows elimination of the T-Intersection. The cul-de-sac, as shown roughly
sketched, violates the Town of Garner's Maximum Cul-de-sac Length Use Ordinance
Article XIV, Section 217 ( c ), which is more stringent than all the municipalities in this
area. Even with this additional connection of Street E we are inclined to believe that
we may still encounter problems with the Ordinance and or the Town's Board of
Alderman. Any changes to the street alignments will require re-approval which will
take considerable time and incur lost finances. Also coupled with this connection is
the fact that extending Street E will violate the Town's horizontal and vertical design
criteria, not to mention the possible loss of lot(s).
In finalizing the review of Exhibit B please note that the total wetland impacts at this
location are the same with or without the T-Intersection.

increase, 1,790 SF, is located in Zone 2.
the total increase is 2,760 SF.
SUMMARY
Neuse River Buffer Impacts (highlighted
Please note that the majority of this net
The net increase in Zone 1 is 970 SF and
A review of Exhibits A and B reveals no additional wetlands being impacted by the
intersection. After reviewing Exhibits C, D, E and the actual field topo (prior to
grading), it is my professional opinion that the additional impacted Neuse River Buffer
Area was somewhat ineffective as a buffer for infiltration. The original topo shows
vertical grades to be in excess of 20 percent (latitudinal to wet weather draw). As you
continue in a southerly direction along the wet weather draw, at about the half way
point on Lot 11, the draw and sideslopes flatten out thus allowing the buffer to provide
for biological protection measures as it was intended. Any shifting of Arbor Greene
Drive from its present location will only increase damage to wetlands and buffers and
present further delay in preparing and finalizing the site.
Should you have any questions, please call.
Very truly yours,
Bass ixon Kennedy, Inc.
