Charlie,
With regards to the maintenance access road for the pipe, I will need a little more documentation. Can you
provide a drawing that shows topo lines on it for the area we are talking about. Show a rough est. of where the
road fill would have to be so we can see how much of the wetland would be impacted. Basically if its 10 square
feet, that might be preferable to the perennial stream impact.
If the wetland fill is small and you still want to try to justify the pipe in the dam breach, we would need more
specific details about why the storm sewer pipe elevation could not be modified. As we discussed on the phone,
there are impossibilities and inconveniences. I need to show its the first and not the second in order to issue a
permit. All this goes to proving avoidance and minimization. I'm not saying your arguments aren't valid but I
need to make sure that my files are sufficiently documented on the rare chance we are sued for issuing a permit.
Thank you

Andy and Sue,
Please see attached several files containing requested clarifications for the Innisbrook PCN.
See also Jason's email below - he has provided a construction sketch for the pump-around and a letter addressing the
routing of the stormwater pond maintenance access road. He has also corrected the mismatched impact lengths given
on page 9.
I've attached the revised full PCN with the temporary impact added to tables and narrative. Also, a highlighted version
of pages 3-5 with the changes/amendments, just to make it as easy as possible for you.
Please let me know as soon as possible if there is anything else you need to complete the review process.
Thanks,
Charlie

Charlie,
Hopefully the attached pdf file is the information you need - 2 detail sheets for the culvert installation, 1 letter
explaining the pond access and the utility impacts.
Please let me know if you need anything else, and I will be glad to help. Thanks.

Jason,
Per our conversation this afternoon, the coffer dam impact is temporary so it will not count against any
thresholds. All I'll need is a sketch of the pump-around - I'll put that and your language below into a revision
and send it to USACE/DWQ.
Another thing I DO need, though, is that confirmation (plat or just a statement from you) showing that there are
no additional impacts from utility lines.
I'll put all three of these pieces (coffer-dam, no road around pond, no utility impacts) into a 'modification to
application' letter and get it to USACE/DWQ; I'd like to do this ASAP to avoid getting a formal "Request for
More Information" letter.
Thanks,
Charlie

It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Two permanent impacts to
perennial streams, totaling 147 LE to place culverts, one for access necessary for maintenance of a
stormwater pond, the other secondary to widening of the adjacent public road. One impact to an
intermittent, "unimportant" stream, totaling 265 LE for parking areas and building pads. Five
permanent wetland impacts, totaling 0.09 acre, for grade slopes for buildingpads and parking areas. reas.

Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USACE.
8. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.

local stormwater requirement, etc.):
Current land use in the vicinity of the pond:
Size of watershed draining to pond: Expected pond surface area:
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. Wet Detention Pond 41 relocated
to avoid impacting intermittent stream. Stormwater conveyance pipes cross perennial stream at existing
culvert with no impact. Headwall placed behind Bldg 7 to minimize grading impact. Headwall placed
along eastern edge of former pond (near Bldg 3) to avoid impact. All riprap to minimum length necessary
to achieve non-erosive velocities. Culvert (Impact 1) uses inlet `flare' to minimize impact. Grade slope
behind Bldg 5 increased (2.5:1) to minimize impact. Culvert impact occurs in low-quality section of
stream (breach in prior existing dam). Parking areas near Bldg 7 have locations dictated by fire codes;
parking cannot be relocated behind Bldg 5 due to buffers or behind Bldg 1 due to setbacks. Temporary
impact from coffer-dam pumparound will be removed immediately following culvert placement and
restored to original grade and contours.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Updated 11/1/2005
Page 5 of 8
USACE - In 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.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina (see DWQ website for most current
version.).
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
No mitigation is proposed at this time.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://www.nceep.net/pa.ges/inlieureplace.htm. If use of the NCEEP is proposed,
please check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet):
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Two permanent impacts to
perennial streams, totaling 147 LE to place culverts, one for access necessary for maintenance of a
stormwater pond, the other secondary to widening of the adjacent public road. One impact to an
intermittent, "unimportant" stream, totaling 265 LE for parking areas and building pads. Five
permanent wetland impacts, totaling 0.09 acre, for grade slopes for buildingpads and parking areas. reas.
One temporary impact of 10 LF as necessary for coffer-dam pump-around during culvert installation
at Stream Impact 41 (Stream impact 42 will have coffer-dam within existing upstream culvert).

3. List the total acreage (estimated) of all existing wetlands on the property: 2.72
4. Individually list all intermittent and perennial stream impacts. Be sure to identify temporary
impacts. Stream impacts include, but are not limited to placement of fill or culverts, dam
construction, flooding, relocation, stabilization activities (e.g., cement walls, rip-rap, crib
walls, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed,
plans and profiles showing the linear footprint for both the original and relocated streams
must be included. To calculate acreage_ multiDly length X width- then divide by 43.560.

7. Isolated Waters
Do any isolated waters exist on the property? ? Yes ® No
Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USACE.
8. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.):
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):
Current land use in the vicinity of the pond:
Size of watershed draining to pond: Expected pond surface area:
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. Wet Detention Pond 41 relocated
to avoid impacting intermittent stream. Stormwater conveyance pipes cross perennial stream at existing
culvert with no impact. Headwall placed behind Bldg 7 to minimize grading impact. Headwall placed
along eastern edge of former pond (near Bldg 3) to avoid impact. All riprap to minimum length necessary
to achieve non-erosive velocities. Culvert (Impact 1) uses inlet `flare' to minimize impact. Grade slope
behind Bldg 5 increased (2.5:1) to minimize impact. Culvert impact occurs in low-quality section of
stream (breach in prior existing dam). Parking areas near Bldg 7 have locations dictated by fire codes;
parking cannot be relocated behind Bldg 5 due to buffers or behind Bldg 1 due to setbacks. Temporary
impact from coffer-dam pumparound will be removed immediately following culvert placement and
restored to original grade and contours.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
