LI LIVESTAKING
DESCRIPTION
Live stakes arc cur and partially stripped portions ofliving, -herbaceous plant material that form a root mass shortly
aloe plantme The portions or "cuttings" are long enough to be tamped into the ground as living plant material that will
grow into mature shrubs capable ofholding wil in place under erosive conditions.
EFFECTIVENESS
Curinas that become established its slwhs are very effective at stabilising wil. However, they offer little value in terms
of soil stability when they are initially installed and should be used in combination with a cover crop whenever possible
Live making is an effxtive technique when construction time is limited and an inexpensive, simple method is sufficient.
The tunings also function as pins to hold core material in place after installation and contribute to the formation of
excellent riparian habitat over time.
CONSTRUCTION GUIDELINES
I. The cuttings must be alive, with side branches removed and taken from species that quickly regenerate
their root systems. The butt ends should be cleanly cm at an angle for easy intention into the wil.
Cuttings should be kept fresh and moist and installed on the sine day they we harvested and prepared for
planting.
-. Tamp the mttingsinto the grand at right angles to the slope. Cutting should be stuck into the ground in
approximmelygO'AOrfour-fdlhsofthehtenmh. The wil should then be packed firmly around the base
ofthe stake. Any cuttings that split during installation should be replaced.
3 The density ofthe installation depends on the specific sins conditions, ranging from two (2) to four (4)
tunings per square meter. The stakes should be placed in random fashion to avoid gullies from foaming
and to produce a more natural effect.
1.2 JOINT PLANTING
DESCRIPTION
This technique utilizes live sakes in between previously placed cobbles. It is intended to immase the
effectiveness of a conventional erosion control by forting a living root mass and water filtration system in the
material base on which the cobbles have been placed. This technique can be used with conventional erosion
control where cobbles are specified and will enhance riparian habitat development. It also provider immediate
protection for high torrent, map gradient mram smems and assins in dissipating some ofthe energy along
stwalllhank.
CONSTRUCTION-GUI DELINES
I. Work must occur in the dormant season of the live plant material that is specified for installation.
-. The cuttings most be alive with side branches removed and taken from specie that quickly regenerate their
root systems. The butt ends should be cleanly sus a an angle for easy insertion into the wil. Cuttings
should be kept fresh and moist and installed on the came day they are harvested and prepared for planting,
3. Tamp the cuttings into the grad at fight angles to the slope. Cutting should be stuck into the ground to
approximmely 80% or farfifthsof their length. The wil should then be packed fiamly around the ban of
the nuke. Any wrongs that split during installation should be replaced.
4. The densityoffhe installation depends on the specific site conditions, ranging from two(2) to four (4)
cuttings per square meet. The stake should be placed in random fashion to avoid gullies from f ing
.
and to produce a more natural effect

Dear Ms. Mueller,
Please reference the May 29, 2003 letter from your office to Mark Vosberg of our firm. Also, please be
advised that Mr. Vosberg is no longer with our company-please direct all future correspondence to my
attention.
Thank you for taking the time to discuss the contents of the DWQ letter with me on June 4, 2003. The
following points clarify, respond to, or discuss the points in the DWQ letter, and are in keeping with our
telephone discussion. I trust that I am accurate in my recollection of our discussion-however, if not,
please correspond back to me and we will go from there.

therefore an evaluation of "health and appearance", etc., of only vegetation is not proposed.

Re: Comments on Eagle Ridge Golf Community "1St Quarterly Management and
Monitoring Report
Dear Mr. Vosberg:
DWQ received your letter dated May 20, 2003 on May 21, 2003, along with the attached copy of
the USACE permit #199920576 dated February 7, 2000 and the "Compensatory Mitigation Plan:
Eagle Ridge Development and Golf Course." There are several monitoring requirements in these
two documents. Criteria that are not being successfully addressed in the "1St Quarterly
Management and Monitoring Report" include:
1. General Mitigation Monitoring:
a. "An as-built report will be produced at the terminus of the mitigation
construction ... for the wetland creation and for the stream restoration."
Concern: The Wetlands1401 Unit has not received an as-built reportfor the wetland
creation or stream restoration areas. The as-built plans should depict sample plots,
individual plant species utilized including numbers of individuals, location of
monitoring wells, and final project elevations.
b. "Bimonthly site visits will take place over the first two years and extend to quarterly
visits over the final three years."
Concern: Here are no dates listed for non-treatment site visits in the "Final
Mitigation Management Schedule and Status Report. "
2. Emergent Wetland Mitigation:
a. "Prohibited activities within the mitigation area specifically include, but are not
limited to...removal, damage, or other alteration of any vegetation... except as may be
authorized by the mitigation plans"
Concern: The "Final Mitigation Management Schedule and Status Report"
describes applying for a variance for control burn, "per HOA reps request. " Control
burn should only be used for controlling invasive species. Selective use of herbicides
and other treatments is already scheduled for April 1 - Oct. 31, 2003.
b. "The permittee will monitor the site in August or September of each year, and
document mortality and stress within the mitigation site. The permittee will '141

monitoring until the sample plots demonstrate 85 % aerial coverage, by the target
species or species acceptable to the Corps of Engineers, for five consecutive years."
Also, "The tertiary goal is the establishment of hydrophytic vegetation, where success
will be set as an 85% cover over the mitigation area by FAC-OBL
vegetation... Qualitative assessments of vegetation gradation from upland to open
water as well as quantitative assessment of floral diversity, density and aerial cover
will be determined at each site visit for both the wetland creation site."
Concern: Vegetation survey dates are not listed in the "Final Mitigation
Management Schedule and Status Report. " A sampling plan must be proposed (e.g.
permanent quadrats, random quadrats, transects, etc.) to measure species presence,
density, and percent cover of native and invasive species. The wetland indicator
status of each species should be noted to meet the 85% cover by "FAC-OBL"
criteria.
c. "The permittee will monitor site hydrology through the use of monitoring wells on
the wetland mitigation site ...and must document attainment of the site's hydrology
success criteria (inundation or saturation within the upper 12 inches of the soil for a
minimum of 12.5 % of the growing season every year of normal precipitation)."
Concern: Shallow monitoring wells are better "to investigate when a free water
surface is within the top foot or two of the soil. " Piezometers (which are currently
being used) assess ground-water discharge and recharge, direction and rate of water
flow, and water flow in different strata when used in clusters or nests (WRP
Technical Note HY-IA-3.1 Installing Monitoring Wells/Piezometers in Wetlands).
Shallow monitoring wells should be used and sufficiently monitored during the
growing season to determine if the success criteria of 12.5% of the growing season is
met. Single values for two of eight piezometers are insufficient data for determining
hydrologic success.
d. Typha latifolia will consist of volunteers only.
Concern: All reports and plans state that Typha lati olia will be volunteers only.
Ensure that all supplemental plantings only include species from the proposed
planting list.
e. "Additionally, an annual wetland delineation will be undertaken at the wetland
creation site,"
Concern: The "Final Mitigation Management Schedule and Status Report" does not
show scheduled times for the annual wetland delineation.
3. Stream Mitigation:
a. "The permittee shall visually monitor the vegetative plantings on all mitigation
stream banks to assess and insure complete stabilization of the mitigation stream
segments."
Also, "[T]he establishment of a forested riparian buffer adjacent to the renewed
channel is an attainable goal which can be quantified on an annual basis with growth
and cover measurements as well as qualified with visual evidence of streambank
stabilization."
Concern: Vegetation survey dates are not listed in the "Final Mitigation
Management Schedule and Status Report. " Annual site walk throughs should be done
to make general observations, search for problem areas, and assess the general
health and appearance of planted vegetation. A sampling plan should be proposed
(e.g. permanent quadrats, random quadrats, transects, etc.) to measure species
presence, density, growth, and percent cover of native and invasive species.
4. Other Concerns:
a. Control burns are proposed for wetland and riparian buffer areas between Nov. 1-
Dec. 31, 2003. These burns are proposed within one year of installation of live stakes
and planting of vegetation. This burn will kill all planted species requiring a
complete re-planting. A correct application of herbicides should sufficiently control
invasive species.
b. Post construction dimension, pattern, profile, and material information is needed for
the restored stream.
c. The photographs should have a greater representation of the wetland creation areas
being used for mitigation credits, and less of the mesic and wet-mesic areas which
were designed to consist of FAC and FACU species.
d. Riprap, step pools, and other construction changes were placed on site without prior
approval from the DWQ office.
The goal of these revisions is to help establish and maintain viable wetland and stream areas.
Please provide a response to these issues and revised reports/plans by July 1, 2003. If you have
any questions or need further assistance, please do not hesitate to contact Amanda Mueller at
(919)733-1786.

will be determined at each site visit for both the wetland creation site."
Concern: Vegetation survey dates are not listed in the "Final Mitigation
Management Schedule and Status Report. " A sampling plan must be proposed (e.g.
permanent quadrats, random quadrats, transects, etc.) to measure species presence,
density, and percent cover of native and invasive species. The wetland indicator
status of each species should be noted to meet the 85% cover by "FAC-OBL"
criteria.
c. "The permittee will monitor site hydrology through the use of monitoring wells on
the wetland mitigation site ...and must document attainment of the site's hydrology
success criteria (inundation or saturation within the. upper 12 inches of the soil for a
minimum of 12.5 % of the growing season every year of normal precipitation)."
Concern: Shallow monitoring wells are better "to investigate when a free water
surface is within the top foot or two of the soil. " Piezometers (which are currently
being used) assess ground-water discharge and recharge, direction and rate of water
flow, and water flow in different strata when used in clusters or nests (WRP
Technical Note HY-I4-3..1 Installing Monitoring Wells/Piezometers in Wetlands).
Shallow monitoring wells should be used and sufficiently monitored during the
growing season to determine if the success criteria of 12.5% of the growing season is
met. Single values for two of eight piezometers are insufficient data for determining
hydrologic success.
d. Typha latifolia will consist of volunteers only.
Concern: All reports and plans state that Typha latifolia will be volunteers only.
Ensure that all supplemental plantings only include species from the proposed
planting list.
e. "Additionally, an annual wetland delineation will be undertaken at the wetland
creation site,"
Concern: The "Final Mitigation Management Schedule and Status Report" does not
show scheduled times for the annual wetland delineation.
3. Stream Mitigation:
a. "The permittee shall visually monitor the vegetative plantings on all mitigation
stream banks to assess and insure complete stabilization of the mitigation stream
segments."
Also, "[T]he establishment of a forested riparian buffer adjacent to the renewed
channel is an attainable goal which can be quantified on an annual basis with growth
and cover measurements as well as qualified with visual evidence of streambank
stabilization."
Concern: Vegetation survey dates are not listed in the "Final Mitigation
Management Schedule and Status Report. " Annual site walk throughs should be done
to make general observations, search for problem areas, and assess the general
health and appearance of planted vegetation. A sampling plan should be proposed
(e.g. permanent quadrats, random quadrats, transects, etc.) to measure species
presence, density, growth, and percent cover of native and invasive species.
4. Other Concerns:
a. Control burns are proposed for wetland and riparian buffer areas between Nov. 1-
Dec. 31, 2003. These burns are proposed within one year of installation of live stakes
and planting of vegetation. This burn will kill all planted species requiring a
complete re-planting. A correct application of herbicides should sufficiently control
invasive species.
b. Post construction dimension, pattern, profile, and -material information is needed for. .
the restored stream.
c. The photographs should have a greater representation of the wetland creation areas
being used for mitigation credits, and less of the mesic and wet-mesic areas which
were designed to consist of FAC and FACU species. .
d. Riprap, step pools, and other construction changes were placed on site without prior
approval from the DWQ officer
The goal of these revisions is to help establish and maintain viable wetland and stream areas.
Please provide a response to these issues and revised reports/plans by July 1, 2003. If you have

Monitoring
Dear Ms. Mueller,
Please reference the May 29, 2003 letter from your office to Mark Vosberg of our firm. Also, please be
advised that Mr. Vosberg is no longer with our company-please direct all future correspondence to my
attention.
Thank you for taking the time to discuss the contents of the DWQ letter with me on June 4, 2003. The
following points clarify, respond to, or discuss the points in the DWQ letter, and are in keeping with our
telephone discussion. I trust that I am accurate in my recollection of our discussion however, if not,
please correspond back to me and we will go from there.
l.a. As-built design drawings are not contemplated to be prepared. The conceptual designs prepared by
Spangler Environmental, Inc. that were forwarded to your office for review last year, and in response to
the failure of the systems in the field as noted by Todd St. John previously, were implemented and are
intact as prescribed. They are in accordance with the permit issued by the Corps and the conditional 401
by the State. We intended for our first Quarterly Monitoring Report to function as a description of the
existing condition of the mitigation area and the stream relocation area. eA menF ov Lori
l,c?n?I'r
/' v r s + °}s, nut nc??- ?n
?S
Lb. Non-treatment sites are not part of the scope of the permitted mitigation or stream relocation. As men-t- 51'
Non-treated sites are not relevant to the issue at hand, no schedule for visiting them is necessary.
2.a. Controlled burning is not feasible, and was abandoned as a means to control invasive seed material.
Per the specifications in the plans, selective herbicide application was used, and was coupled with t/
draining the pond and hand cutting/stump removal in the mitigation area. With the exception of some
willow stumps that remained, this appears to have been an effective substitution to the burn.
2.b. Vegetation survey dates will be pursuant to the conditions in the Corps permit and the 401
Certification (annually), or more frequently as recommended in the monitoring reports (bi-
monthly). As discussed by telephone, specific calendar days are not feasible to identify at this time. As
stated in the documents, vegetation will be sampled on transects from upland to open water. No
additional sampling plans are proposed. nerd -1-0 k%k tr4nse&s 4 ?vadrA - sparrni ?s`r?
2.c. Because of the constructed topography in the vicinity of the created wetland mitigation area, the
impoundment of the intermittent stream to create the mitigation area, and its proximity to the lake at the
golf course, piezometers will continue to be used for monitoring hydrologic conditions. Shallow

monitoring wells will be placed in the future within the upper reaches of the mitigation area in non-
inundated areas.
2.d. Should supplemental plantings be necessary, they will include species as identified in the planting
plans.
2.e. Specific calendar days are not feasible to identify at this time. Annual delineations will be O? 7
performed pursuant to the approved mitigation plans.
1 +0
3.a. Specific calendar days are not feasible to identify at this time. We are aware of the purpose of ?Je?ss ?L?
annual walk-through, which in this case is more comprehensive than the vegetation evaluations identified
in the DWQ letter. Annual assessment will be for the purpose of insuring complete stabilization of the
mitigation stream segments, as stated in the Permit, Certification, and subsequent documents, and
therefore an evaluation of "health and appearance", etc., of only vegetation is not proposed.
4.a. While we disagree that a controlled, prescribed burn for the purpose identified "will kill all planted
species requiring a complete re-planting", the point is moot since the Town Fire Marshall will not issue a
permit for this purpose in this location. ?k
4.b. All requested information is included in the construction plans and the monitoring reports. We plan
to include qualitative and quantitative information as to these items in future monitoring reports.
4.c. Photographs are for ease of reference only, however concentrating documentation on the marginal
areas of the wetland creation area is more important to document success than concentrating on
impounded areas where the hydrology criterion is met by definition.
4.d. No changes to the submitted plans were made. All construction was according to the plans
submitted to your office.
In summary, we look forward to our next submission of monitoring data, at this time scheduled for the
month of July 2003.

Re: Comments on Eagle Ridge Golf Community "1St Quarterly Management and
Monitoring Report
Dear Mr. Vosberg:
DWQ received your letter dated May 20, 2003 on May 21, 2003, along with the attached copy of
the USACE permit #199920576 dated February 7, 2000 and the "Compensatory Mitigation Plan:
Eagle Ridge Development and Golf Course." There are several monitoring requirements in these
two documents. Criteria that are not being successfully addressed in the "0 Quarterly
Management and Monitoring Report" include:
1. General Mitigation Monitoring:
a. "An as-built report will be produced at the terminus of the mitigation
construction ... for the wetland creation and for the stream restoration."
Concern: The Wetlands1401 Unit has not received an as-built report for the wetland
creation or stream restoration areas. The as-built plans should depict sample plots,
individual plant species utilized including numbers of individuals, location of
monitoring wells, and final project elevations.
b. "Bimonthly site visits will take place over the first two years and extend to quarterly
visits over the final three years."
Concern: There are no dates listed for non-treatment site visits in the "Final
Mitigation Management Schedule and Status Report. "
2. Emergent Wetland Mitigation:
a. "Prohibited activities within the mitigation area specifically include, but are not
limited to...removal, damage, or other alteration of any vegetation... except as may be
authorized by the mitigation plans"
Concern: The "Final Mitigation Management Schedule and Status Report"
describes applying for a variance for control burn, "per HOA reps request. " Control
burn should only be used for controlling invasive species. Selective use of herbicides
and other treatments is already scheduled for April 1- Oct. 31, 2003.
b. "The permittee will monitor the site in August or September of each year, and
document mortality and stress within the mitigation site. The permittee will continue

monitoring until the sample plots demonstrate 85 % aerial coverage, by the target
species or species acceptable to the Corps of Engineers, for five consecutive years."
Also, "The tertiary goal is the establishment of hydrophytic vegetation, where success
will be set as an 85% cover over the mitigation area by FAC-OBL
vegetation... Qualitative assessments of vegetation gradation from upland to open
water as well as quantitative assessment of floral diversity, density and aerial cover
will be determined at each site visit for both the wetland creation site."

Dear Mr. Alsmeyer:
Pursuant to US Array Corps of Engineers Action ID #199910576, please find the enclosed
management and monitoring report, dated April 22, 2003.
As we discussed in our September 30, 2002 correspondence, this report contains a more detailed
quantitative assessment such as piezometer readings for estimating the area of saturation within
the wetland creation area, average channel width to depth ratios in the stream relocation area and
a ranking of the relocated stream utilizing the NCDWQ Stream Classification Form. Starting in
mid-July of this year, our three remaining quarterly reports will also include percent areal
coverage of native species throughout the mitigation areas.
If you have any questions regarding this report or our final mitigation management schedule,
please call.

1. General Ecological Condition: The restoration of a freshwater marsh in the wetland creation area, and the restoration of the
streambank in the stream relocation area appear to be proceeding in a predictable, linear fashion, i.e. the eradication of non-native
and/or invasive species from the wetland creation area has eliminated interspecific competition between trees and shrubs and
increased the areal coverage of herbaceous species (Photos 1 - 3); and recontouring, cobbling and the installation of in-stream
structures have reduced or eliminated down cutting and bank scouring in the stream relocation area's middle reach (Photo 5 - 6).
2. Hydrologic Observations: The flashboard riser in the wetland creation area appears to be holding water at elevation 290' as
designed (Photo 4); an increase in width to depth ratio from an average of 3.875:1 to an average of 6.776:1, and the installation of
cobbles and in-stream structures appear to have decreased velocity and bank scouring throughout most of the stream relocation area's
upper and middle reach (Photo 5 - 6).

RE: Eagle Ridge Golf Course Community Mitigation Areas L? ?0
SEI Project No. 9905022
Dear Ms Muller:
Pursuant to your request, please find the enclosed documentation in support of our restoration efforts at
Eagle Ridge Golf Course Community. The original construction was not successful. We performed the
re-construction of both the stream and wetland area earlier this year.
You will note that our September 3, 2002 monitoring report showed a deficiency in the wetland
community-type that was intended for the mitigation. It now appears that a freshwater marsh will
develop under a modified hydrologic regime and the completion of site-specific management activities,
pursuant to the original intent of the mitigation effort. Similarly, the erosion due to down cutting and
bank scour in the restored stream relocation that was prevalent when Todd St. John, et. al. last visited the
site in early 2002, does not now appear to be a contributing factor to downstream sedimentation or
turbidity. The stream banks have remained intact, and our plants installed on the banks are in excess of
the density necessary for Neuse Buffer mitigation compliance - even though this site was grandfathered
from the Neuse Rules.
In summary, it now appears the onsite restoration of a marsh and stream will proceed in a predictable,
linear fashion, despite the short time frame for construction and compliance.
Please call if you have any questions or concerns.
Sincerely,
Spangler Environmental, Inc.

Compensatory Mitigation Plan
Eagle Ridge Development and Golf Course
Prepared By: Spangler Environmental Consultants, Inc.
Prepared For: Sandler at Old Stage Road L.L.C.
Introduction
The Eagle Ridge Development and Golf Course lies within the Swift Creek watershed,
south of the Town of Garner in Wake County, North Carolina. The 534 acre property is
south of Swift Creek and is bound on the east and west by Old Stage Road and the
Norfolk Southern Railroad, respectively. The property can be found on the Garner
1),-1ranale man (T TSGS 1:24.00() --ale) and Wake County Soil Survey sheet #85.
The development of the residential areas and golf course will result in an impact to 0.42
acres of wetlands and 1115 linear feet of stream which will require mitigation. These
numbers represent the final impact figures after all practicable avoidance and
minimization activities were exhausted on the site. This document represents a plan for
the satisfying the compensatory mitigation requirements for L11c _"6-
Wetland Creation and Preservation
A total of 0.63 acres of wetlands will be created on-site (see attached conceptual plan).
The wetlands slated for fill are found in an abandoned stream channel adjacent to the
Norfolk Southern Railroad. These palustrine emergent wetlands will be replaced in-kind
at a mitigation ratio of 1.5:1. The mitigation wetlands will be created at the eastern
headwaters of the proposed lake that will be at the center of the development.
Construction will be concurrent with the construction of the dam for the lake.
An additional 4.2 acres of wetlands will be preservea on the ,w11L ?.';ek floodplain. This
land is currently under ownership by Sandler. However, the majority of the Swift Creek
floodplain area will be deeded to the Town of Garner and the preserved wetlands will be
placed in a conservation easement and granted to the North Carolina Wetland Restoration
Program. Though the preservation aspect of the Eagle Ridge mitigation will not be in-
kind, the preserved palustrine forested wetlands occur more infrequently in the Piedmont
than freshwater marsh, and it is typically considered a beneficial out-of-kind mitigation
option. These wetlands will be preserved at a mitigation ratio of 10:1, giving a
cumulative mitigation ratio of 11.5 acres of wetlands created or protected to every 1 acre
of wetland impacted by site development.
Stream Restoration and Enhancement
A total of 1050 feet of stream restoration will be undertaken on-site (see attached, revised
plan). Currently a stretch of perennial stream adjacent to Norfolk Southern Railroad is
channelized, incised, and unstable. This stream will be re-routed through the floodplain
to restore the natural sinuosity and slope. The banks will be stabilized and a forested
riparian area will be restored along both banks.
An additional 500 feet of stream enhancement will occur up- and downstream of the
restored stream. Due to constraints in designing the on-site golf course in proximity to
the restored stream, forested riparian zones cannot be restored along these areas.
However, the
ove.
restoration work will be identical to that outlined ab
_ r n
In total, 1,550 linear feet of work will take place to improve Ule 1LU1%,uv1ia1 11"L . -- --
straightened stream on the site. At a mitigation ratio of 1:1 for the restoration and .5:1 for
the enhancement, 1250 linear feet of compensatory mitigation could be fulfilled on site.
Any balance of the mitigation quantities would be satisfied with payment to the North
Carolina Riparian Restoration Fund.
Target Endpoints for Mitigation Areas
Wetland Mitigation
The primary goal is to replace wetlands on the Eagle Ridge landscape above the air,
that was impacted due to site development (0.63 to 0.42). The goal is to replace these
wetlands in-kind (freshwater marsh), but to do so in a landscape position where they will
have greater functional ability, and thus greater value to society. Lying at the headwaters
of the lake and fed by streams that run through the developed property, the functional
goals of these created wetlands are to provide water quality treatment, sediment retention,
and increased fish and wildlife habitat. The attainment of these goals is based on the
development of a healthy marsh ecosystem that is dominated by hydrophytic veaPtnt;nn.
This goal is measurable through annual wetland delineations to determine the extent of
created jurisdictional area.
Stream Mitigation
The primary goal in undertaking stream improvements on the Eagle Ridge site is to
renew a natural sinuosity and stabilized channel structure to the straightened stretch of
stream. This channelized area has under cut its banks in a number of places, leading to
stream bank slumping and increased sediment transport downstream. These conditions
have begun to migrate in an upstream direction. Without intervention, the stream incision
will continue to spread upstream through the tributary system while increased
sedimentation will continue downstream. In order to accomplish this restoration goal, the
geomorphology of the present channel must be adjusted and a healthy riparian zone will
have to be established around the new channel.
A natural geomorphologic stream structure will stabilize the banks and equalize the
sediment supply. This will prevent continued upstream migration of the stream incision.
It will also increase the number of habitat niches that are available within the stream by
recreated a riffle-pool sequence. Rusgen stream classification (Level I, II) was carried
out on-site, above and below the degraded area, to determine the necessary
geomorphologic characteristics of the restored area. The stream will need to portray 134-
B5 characteristics. The slope should be very close to 0.02, sinuosity (stream
length/valley length) should be close to 1.35, entrenchment ratio (width of the floodprone
area at an elevation twice the maximum bankfull width/bankfull depth) should be
approximately 1.6, and width/depth ratio (bankfull width/ mean bankfull depth) shouia be
approximately 16. The substrate should be dominated by gravel and sand with lesser
amounts of boulders, cobble, and silt. Pool to pool spacing should be four bankfull
channel widths. The goals of the geomorphologic renewal are both measurable and
attainable, and the success of the endeavor can be quantifea on an amiuai uaai?).

immediate stream bank area, intercept stream-bound pollutants, provide for temperature
regulation, eventually become a source of large woody debris within the stream. and
increase wildlife habitat. Though any area that is disturbed during the site construction
process will need to progress through typical successional stages, the establishment of a
forested riparian buffer adjacent to the renewed channel is an attainable goal which can u'.?
quantified on an annual basis with growth and cover measurements as well as qualified
with visual evidence of streambank stabilization.
Mitigation Vegetation
Wetlands
The vegetation in the created wetlands will closely mimic that from the impacted area.
The semipermanent source of water over much of the mitigation site will necessitate
hardy freshwater marsh species such Juncus effusis, Cyperus strigosis, Eleocharis spp.,
Carex spp., Typha latifolia (volunteer only), and Salix nigra. The seeds will be mixed,
broadcast planted, and disk :d into the soil. This will allow the hydrophytic vegetation to
arade into zones based on the water levels over the creation site.
Streams
The streambanks will initially be stabilized with willow planting, though alder volunteers
will likely establish in the primary successional stages. The riparian zone will be planted
with typical bottomland hardwood species such as Quercus nigra, michauxii, and phellos,
Betula nigra, Cephalanthus occidentalis, Fraxinus pennsylvanica, Ulmus americana,
Carpinus caroliniana, Acer rubrum (volunteer only), and Liquidambar styraciflua
(volunteer only). Where it is practicable, the construction and access for the channel
renewal will completely avoid the existing forested vegetation. The combination of
avoidance and seed plantings will accelerate the establishment of the forested vegetation
in the riparian zone. Broadcast planting with a seed mix of the above species followed by
disking of the soil will put the tree species in contact with nutrients and uncompacted
earth.
Mitigation Soils
Wetlands
The soils in the wetland creation areas are mapped as Wedowee sandy loams in the Wakc
County Soil Survey map #85. These soils are described as having low organic matter,
moderate permeability and shrink-swell potential, a meatum water capacity, uni beill,
aeidis In girder to establish vegetation at these sites, the pH will have to be raised and
fertilizer added. On a substrate such as this, it is possible that a low diversity community
will establish primarily. However, the continual addition of organic matter through plant
decay as well as nutrient and sediment trapping by the vegetation should foster a gradual
increase in diversity over time. Additionally, the flooding of these soils and consequent
,, .+nr rn?iacic {XI;11 oln- f1,P rate of r1PPn,nnosition, further building organic matter.
Streams
The soils in the stream restoration area are mapped primarily as Wehadkee and Bibb silty
and sandy loams. These are frequently flooding but short flooding duration soils.
Surface runoff is slow but infiltration is fair to good. The stream throughout this
floodplain is situated within a well-dettnect channel, though there is ample evidence that
its course has meandered across the floodplain. This is, in part, a result of the
Wehadkee/Bibb soil makeup. The establishment and preservation of a forested buffer
around the majority of this restoration area should temper the meandering of the stream.
It also precludes the need for very aggressive stabilization of the streambank to prevent it
from meandering and infringing on any on-site development.
Mitigation Hydrology
Wetlands
Because the wetland creation area is found at the headwaters of a lake, hydrology
information for the lake is sufficient for the determination of wetland hydrology
conditions. The normal pool elevation of the lake will be 288 feet. Inputs into the lake
will equal outputs through the outlet structure through the dam. The top of the dam will
be 296 feet, a water level that could only be attained under a very large storm with wind
and waves from the south to north.
The lakeward edge of the creation site will be at elevation of 286 feet, behind a 2 foot
berm along the lakeshore. This berm will be stabilized with geotextile fabric to guard
against short term erosion and allow for longer-term vegetation stabilization. From the
inlet to the creation area to the lakeshore, the slope will not be greater than I%, and the
side slopes of the creation area will not be steeper than 10:1. Such gradients should lead
to the inundation/saturation of the entire creation area at least semipermanently. Flow
on structures will be placed at the inlets to the creation area to deter an incised
channel from forming. The water table in the wetland will only drop below 288 ft.
elevation if the tributaries feeding the creation area go dry. The incidence of this will be
less when the site is developed and the quantity of impervious surface increases.
The length to width ratio of this area is roughly 10:1. This will increase residence time
an? _:_ .eas i,_ .nitial for "short-circuiting" within the creation unit while slowing
runoff flows into the lake. HEC-HMS modeling was conducted for the various sub-
basins entering the lake. Total volume per hour was computed at .86, 1.16, 1.3 9, and
1.6? ac.-ft./hr. ?. rr. - , 75 5n ,a 1 no \'PA, ?- n sto,.,-, -
respectively, at the junction of the streams within the lake immediately downstream of
the creation site. With a wetland creation area of 0.63 acres at an average depth of 1.5
feet, the resulting volume is .95 acre-feet. Therefore, discharge would be held within the
wetland unit during a 10 year, 24 hour storm event, but spill out of this area in larger
events.
With these considerations, it is likely the mitigation area will be permanently flooded to
an elevation is at 288 feet, and saturated at elevations higher than this due to the
associated ground water table, throughout the winter months and during spring high
water. The maximum depth in any portion of inundation in the wetland will be 2 feet
adjacent to the berm. Throughout the summer and into the fall, the creation area will be
intermittently pulsed with water due to precipitation events. This runoff will fill the
creation area to an elevation of 288 feet before spilling into the lake. During these low
water periods, portions of the wetland will have extended inundation/saturation due to the
berm at the lakeward edge holding water within the creation area.
Streams
Upstream of the restoration area, the stream channel is somewhat incised. Though this
incision is not structurally dangerous to the stream bank, it does limit the flooding of the
banks. The restored stream will not be designed with this degree of incision, but rather
toward a natural state that floods its banks during larger precipitation events. Such flood
flows will enter the riparian buffer that is established along the stream's banks. Such
flooding will allow the stream to dissipate energy and erosive power before flowing off-
site and help to establish flooding tolerant species typical of bottomland hardwood forests
within the riparian buffer.
Mitigation Monitoring
At both the wetland and stream mitigation sites, a five year moniter-ifig Plan will he,
implemented Rimont'k1- cite visits will take place over the first two years and extend to
quarterly visits over the final three years. An "as-built" report will be produced at the
terminus of the mitigation construction, and a annual monitoring report will be produced
for the wetland creation and for the stream restoration.
Additionally, gal wetland delineation will be undertaken at the wetland creation
site, anu sunsequcIILly 3uhmiLtea *>,e Corps. At e en of f the five
year monitoring cycle, a decision will be made by the Corps as to rc. _
from further monitoring or continuing for an additional period in the manner of the
previous three years.
Wetland Creation Goals
The primary goal in the wetland creation area is to establish wetland hydrology.
-' Piezometers will be installed within the creation area to monitor water table levels. The
wetland gradients have been designed to provide saturated ground water conditions on the
creation area side slopes. The quantification of the goal is to maintain a water table
height within 12 inches of the surface for at least two weeks of the growing season over
the entire mitigation area. This will be measured by placing 5 piezometers in cross
section through the wetland and an additional 3 piezometers around the upper edge of the
wetland. If this is not attained by year 2, the berm on the downslope edge may be
elevated.
The secondary goal is to determine the creation/absence of hydric soil indicators as
defined by the NRCS Regional Indicators of Hydric Soils. The Regional Indicators will
be employed because the offer a more tested approach to delineating between wetland
fringe characteristics and mid-wetland characteristics within the soil profile. If the
creation site begins to show indicators of hydric soil formation along the cross sectional
hydrologic monitoring area and in the vicinity of the other piezometers, it will be
assumed that the water table is high enough to produce reduced soil conditions
throughout the site. Site analysis for these hydric soil indicators will be conducted during
each site visit.
The tertiary goal is the establishment of hydrophytic vegetation, where success will be set
as an 85% cover over the mitigation area by FAC-OBL vegetation by the end of the five
year monitoring period. At an appropriate planting time during year 3, any.. H . -'I'-
less than 30% cover will be re-disked and planted again with seeds of plant species that
are dominant adjacent to the bare area. Qualitative assessments of vegetation gradation
from upland to open water as well as quantitative assessment of floral diversity, density
and aereal cover will be determined at each site visit for both the wetland creation site.
A statement of maintenance needs will be produced following each site visit and
forwarded to the party responsible for the success of the mitigation activities. It is
responsibility of this party to complete the required maintenance.

Re: Comments on Eagle Ridge Golf Community "1St Quarterly Management and
Monitoring Report
Dear Mr. Vosberg:
DWQ received your letter dated May 20, 2003 on May 21, 2003, along with the attached copy of
the USACE permit #199920576 dated February 7, 2000 and the "Compensatory Mitigation Plan:
Eagle Ridge Development and Golf Course." There are several monitoring requirements in these
two documents. Criteria that are not being successfully addressed in the "1St Quarterly
Management and Monitoring Report" include:
1. General Mitigation Monitoring:
a. "An as-built report will be produced at the terminus of the mitigation
construction ... for the wetland creation and for the stream restoration."
Concern: The Wetlands/401 Unit has not received an as-built reportfor the wetland
creation or stream restoration areas. The as-built plans should depict sample plots,
individual plant species utilized including numbers of individuals, location of
monitoring wells, and final project elevations.
b. "Bimonthly site visits will take place over the first two years and extend to quarterly
visits over the final three years."
Concern: There are no dates listed for non-treatment site visits in the "Final
Mitigation Management Schedule and Status Report. "
2. Emergent Wetland Mitigation:
a. "Prohibited activities within the mitigation area specifically include, but are not
limited to...removal, damage, or other alteration of any vegetation... except as may be
authorized by the mitigation plans"
Concern: The "Final Mitigation Management Schedule and Status Report"
describes applying for a variance for control burn, "per HOA reps request." Control
burn should only be used for controlling invasive species. Selective use of herbicides
and other treatments is already scheduled for April 1- Oct. 31, 2003.
b. "The permittee will monitor the site in August or September of each year, and
document mortality and stress within the mitigation site. The permittee will continu

monitoring until the sample plots demonstrate 85 % aerial coverage, by the target
species or species acceptable to the Corps of Engineers, for five consecutive years."
Also, "The tertiary goal is the establishment of hydrophytic vegetation, where success
will beset as an 85% cover over the mitigation area by FAC-OBL
,yegetion ..Qual4a eve assessments of vegetation gradation from upland to open
water as wel 4s qqai ptative assessment of floral diversity, density and aerial cover
will be deter in"e"d of each site visit for both the wetland creation site."
Concern: Vegetation survey dates are not listed in the "Final Mitigation
Management Schedule and Status Report." A sampling plan must be proposed (e.g.
permanent quadrats, random quadrats, transects, etc.) to measure species presence,
density, and percent cover of native and invasive species. The wetland indicator
status of each species should be noted. to meet the 85% cover by "FAC-OBL"
criteria.
c. "The permittee will monitor site hydrology through the use of monitoring wells on
the wetland mitigation site ...and must document attainment of the site's hydrology
success criteria (inundation or saturation within the upper 12 inches of the soil for a
minimum o 12.5 % of the growing season every year of normal precipitation)."
Concern: Shallow monitoring wells are better "to investigate when a free water
surface is within the top foot or two of the soil. " Piezometers (which are currently
being used) assess ground-water discharge and recharge, direction and rate of water
flow, and water flow in different strata when used in clusters or nests (WRP
Technical Note HY IA-3..1 Installing Monitoring Wells/Piezometers in Wetlands).
Shallow monitoring wells should be used and sufficiently monitored during the
growing season to determine if the success criteria of 12.5% of the growing season is
met. Single values for two of eight piezometers are insufficient data for determining
hydrologic success.
d. Typha latifolia will consist of volunteers only.
Concern: All reports and plans state that Typha latifolia will be volunteers only.
Ensure that all supplemental plantings only include species from the proposed
planting list.
e. "Additionally, an annual wetland delineation will be undertaken at the wetland
creation site,"
Concern: The "Final Mitigation Management Schedule and Status Report" does not
show scheduled times for the annual wetland delineation.
3. Stream Mitigation:
a. "The permittee shall visually monitor the vegetative plantings on all mitigation
stream banks to assess and insure complete stabilization of the mitigation stream
segments."
Also, "[T]he establishment of a forested riparian buffer adjacent to the renewed
channel is an attainable goal which can be quantified on an annual basis with growth
and cover measurements as well as qualified with visual evidence of.streambank
stabilization."
Concern: Vegetation survey dates are not listed in the "Final Mitigation
Management Schedule and Status Report. " Annual site walk throughs should be done
to make general observations, search for problem areas, and assess the general
health and appearance of planted vegetation. A sampling plan should be proposed
(e.g. permanent quadrats, random quadrats, transects, etc.) to measure species
presence, density, growth, and percent cover of native and invasive species.
4. Other Concerns:
a. Control burns are proposed for wetland and riparian buffer areas between Nov. 1-
Dec. 31, 2003. These burns are proposed within one year of installation of live stakes
and planting of vegetation. This burn will kill all planted species requiring a
complete re-planting. A correct application of herbicides should sufficiently control
invasive species.
b. Post construction dimension, pattern, profile, and material information is needed for
the restored stream.
c. The photographs should have a greater representation of the wetland creation areas
being used for mitigation credits, and less of the mesic and wet-mesic areas which
were designed to consist of FAC and FACU species. .
d. Riprap, step pools, and other construction changes were placed on site without prior
approval from the DWQ office.
The goal of these revisions is to help establish and maintain viable wetland and stream areas.
Please provide a response to these issues and revised reports/plans by July 1, 2003. If you have
any questions or need further assistance, please do not hesitate to contact Amanda Mueller at
(919)733-1786.

TO: John Dorney and File Copy
FROM: Amanda Mueller OIL
RE: Conversation with Mark Vosberg concerning Eagle Ridge Golf Community
At approximately 11:10 am I received a phone call from Mark Vosberg concerning Eagle Ridge
Golf Community. He identified himself and stated that he had worked on a project (i.e. Eagle
Ridge Golf Community) that I was reviewing. He asked if I could give him some feedback
about his project. At that time Mr. Vosberg did not state that he was calling on behalf of
Spangler Environmental Inc., nor did he state that he no longer worked for them.
I got the letter and began to summarize the comments written in the letter addressed to him at
Spangler Environmental Inc. I informed him of the need for an as-built report, monitoring dates,
and the potential compliance issue of not having pre-approval for cobble and step-pools in the
restored stream. After reading a couple of the comments from the letter to Mr. Vosberg, I
mentioned to him that when I called the office the previous week that the secretary told me, "he
does not work in this office any more." Mr. Vosberg informed me that he no longer worked for
Spangler Environmental Inc. as of May 28, 2003. At that time, I confirmed with Mr. Vosberg
that the reason for his call was to get general comment on his work, and not the specific
comments related to Spangler Environmental Inc. work with the Eagle Ridge Golf Community.
The rest of the conversation with Mr. Vosberg entailed general comments about restoration
projects (i.e. utilizing control burns after the planting of live stakes, using shallow monitoring
wells instead of piezometers to assess hydrology, providing more than one number to assess soil
saturation for the proper duration, ensuring thoroughness of reports, providing as-built reports
and post construction stream data). Mr. Vosberg did not probe for specifics about the project,
just about his general work.. After I made a few comments, he did not seem interested in
receiving further feedback. He seemed content to be finished with the conversation
During our conversation Mr. Vosberg asked if we needed assistance with our restoration work. I
informed him that I was not responsible for hiring in the office and that he would need to contact
John Dorney concerning hiring needs. He also asked my background and I informed him that I
had a master degree in wetland science.
Finally, when I informed him of needing to provide more than one number from hydrologic
monitoring data in order to determine saturation for 12.5% of the growing season, he made an
"un-official [statement] because he no longer worked for Spangler." He mentioned that with the
restoration projects (in general?) they were under strict budget so some things could not be
completed for budgetary reasons. There was not sufficient money to purchase monitoring
gauges or monitor bi-weekly.
