Attachment 1
Detailed Application Data
The purpose of the original permitted impacts provide ingress/egress street access, stormwater
management swales and pipes, and utility infrastructure to include sewer, water line extension,
power /cable /phone to new 57 lot subdivision. The After - The -Fact permit purpose is to widen the
wetland crossing area to allow for a proper roadside Swale cross section to convey stormwater per the
approved stormwater plan.
3e. Describe the overall project in detail, including the type of equipment to be used:
The subdivision ordinance required a sidewalk on one side of the road throughout the entire
development. The stormwater high density permit requires the collection of all the runoff from
impervious surfaces for treatment in the wet detention pond. The site has a particular uniqueness with
the drastic change of elevation culminating near the wetland impact crossings. The wetland connectivity
culverts are properly installed at the natural flow line elevations with 20% burial to allow aquatic life
passage. The road height was designed for an elevation that considered the required separations of
incompatible utilities (sewer, water, stormwater) but not for the wetland culvert. The original permitted
impacts are exceeded some of which resulted from the lack of room within a 50' right -of -way for the
required proper backslope for the stormwater Swale needed to convey runoff past the wetlands.
The overall project details for the After -The -Fact permit application will consist of the following:
1. Construct the back slope berm, shorten the existing wetland crossing culverts and install the
endwalls as per the revised impact crossing plans
2. Remove all unauthorized fill from area outside of the revised plans to the original grade and restore
with native wetland vegetation per the restoration plan include with this application.
3. Have all the utilities relocated to the permitted impact areas and removed from the partial
preservation areas
4. No additional impacts from heavy equipment will occur in the existing wetlands.
5. Heavy equipment used to bring the site into compliance will include back hoe /excavator and dump
truck
Refer to Section D.1. of this application for rational of revised design for the avoidance and
minimization analysis.

5b. Explain detail of permits in accordance of "help" file instructions
CORPS: August 25, 2010; NWP 29; Action ID: SAW- 2009 - 01959; 0.297 acres permitted discharge fill;
impact mitigation = 1.5:1 for fill and wetlands in partial preservation (partial resulted from modification
of standard preservation language to remove clause of "no cut, mow, burn, remove, or harm any
vegetation ").
NCDENR -DWQ: October 22, 2010; Project #: 10 -0727; concurrence with impact on NWP29 issued by
Corps.
D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing
project.
Before any construction activity commenced and in the original PCN submittal, ample survey grade data
was obtained to design the crossings and the drainage network for the whole site. We have the
topography of good elevations in and around all the impact areas which will serve as our target grade for
proposed additional fill impacts intersecting with original contours. The road final grade elevation is a
known variable and exists with each of the six wetland crossing areas. Ultimately, the unapproved fill is
a direct result of the final road elevation being designed too high in relationship with the culverts that
were installed and simulates the natural flow grades through the wetland crossings. During the as -built
survey process, the roadway edge of pavement and sidewalk edges were located at all the crossings. In
order to maintain compliance with the storm water management system permit, each road has a swale
running the length of both sides of the road including over each of the six crossings. As stated earlier
with a high density storm water permit, the entire storm water runoff from built upon areas must been
collected and treated. The permitted stormwater plan set details the Typical Road Cross Section that
was constructed but a stable back slope to convey the water in the swale and not into the wetlands is
needed. The wetland crossing areas have large drops in grade towards the wetlands and the roadside
swale needs additional area outside of the right -of -way to form a true conveyance swale; this is the basis
of this overall request. Therefore, I propose to augment the Typical Road Cross Section permitted by
NC State Stormwater to include a three foot wide berm at a roughly flat grade to stabilize the back slope
of the road side swales (refer to page 7R). In grading to the original elevation, the detail shows
continuing from the berm at a 3:1 slope for 3' (drop P) and then follows a 2:1 slope to original grade.
Only proposed exceptions include NCDOT approved end wall structures on Impacts numbers 4 & 5 in
order to better stabilize the wetland culverts and protect from washout. All utilities will be removed
from the restoration areas but proposed the lines can remain in the 3' stabilization berm area. The
impacted wetlands were in a partial preservation easement — See Section F2c for mitigation comments.
D.l.b. Specifically describe measures taken to avoid or minimize the proposed impacts through
construction techniques.
All lots are sized so that homes will be constructed without any wetland or open water (swale) impacts.
Only impacts are the wetland crossing and the following construction sequence will protect undisturbed
wetlands:
• Remark all wetlands
Filename: 080401 PCN attachment 3- 2013.docx Page 2

• Grade stakes to match plans and process
• Mark end walls and new pipe inverts
• Dig to original elevations with long -arm excavation to limit additional compaction
• USACE to confirm elevations and the soils before planting.

issues resulting from a routine on -site inspection by DWQ. Please refer to the October 15, 2012 written
response to Mr. Jim Gregson and Mr. Shelton Sullivan detailing the corrective action taken and cause
for the NOV. Additionally, On October 4, 2012, a receipt of letter from USACE for non - compliance
with NWP 29 and in violation of the Section 404 of the Clean Water Act for unauthorized discharge in
wetlands. Please refer to the October 15, 2012 written response to Colonel Steven A Baker detailing the
corrective action taken and'cause for the violation. The aforementioned response letters requested an
on -site meeting that was held 11/15/2012 with Mr. David Bailey and Ms. Jennifer Frye of USACE, Ms.
Joanne Steenhuis of NCDENR -DWQ, Hank Gay of Highway 50 Development, Co., Inc. and Ken
Johnson of Charles F. Riggs & Associates, Inc. (agent for developer). The site had been surveyed with
an as-built survey prepared to show the impacts, NC ONE CALL had located all the utilities within the
impact areas and the non - impact related areas had been brought into compliance for the stormwater and
erosion control measures. The ultimate cause of the additional impact is the road elevation being
designed and built too high for a proper stormwater swale with a stable back slope to properly convey
stormwater to the catch basins and wet pond. Complicated by the culvert inverts needed to allow the
aquatic life to connect through the crossing; it was agreed to allow the developer to apply for an after -
the- fact permit. The goal was to minimize any additional impact and provide a restoration plan that
includes monitoring. The proposed additional impacts were explained in section D1 as to the approach
to establish a proper roadside swale and minimize each crossing regardless of other utilities. The
proposed Compensatory mitigation is proposed at 1.5 to 1 for the additional impact and 0.5:1 for
removing previously permitted partially restrictive preservation wetlands from preservation; total
mitigation proposal is 2:1 for 0.26 credits to be paid to the Hofinann Forest Wetland Mitigation Bank.

Draft Restoration Plan for The Reserves at Holly Ridge Subdivision
Onslow County, NC
Introduction:
This restoration plan was created in response to the October 4, 2012 (Action ID #: SAW- 2009 - 01959)
letter from Colonel Steven A. Baker to Mr. Mark Yow & Mr. Harry M. Shaw of Highway 50
Development Company, Inc., the owners /developers of the approximately 21 acres tract being developed
as a residential subdivision known as The Reserve at Holly Ridge in Onslow County, NC , as well as
subsequent meeting and conversations with David Bailey and Jennifer Frye of the US Army Corps of
Engineers (Corps) and Joanne Steenhuis of NC Department of Environment and Natural Resources —
Division of Water Quality. In response, this restoration plan was formulated for submission with an after
the fact permit application.
The restoration plan will be divided into three sections. The impact restoration section will show how the
majority of the previously filled wetlands will be restored to its previous grade and replanted with native
wetland vegetation. The restoration timeline section will document the restoration schedule and the
monitoring section will show the documentation of meeting project success criteria. Please refer to the
after the fact permit application for mitigation locations.
Impact Restoration
A total of 9,198 f? (0.211 acres) of previously impacted wetlands will be restored. The impacted areas
will be restored to the grade of the original elevation as determined by original survey data collected by
Charles F. Riggs & Associates, Inc prior to any impact activities occurring. Additionally, the grade will
be congruent with the adjacent wetlands. The area will be stabilized with appropriate erosion control
measures to ensure that turbidity and nutrient pollution do not affect adjacent water bodies during
construction. Recolonization of the area from adjacent seed bank sources is anticipated to quickly
revegetate the area with native species. The site has uplands adjacent to the impact restoration areas
where colonies of native wetland vegetation have spread. Two of these native plants, Cyrilla racemiflora
and Ilex coriacea, will be transplanted in an equal mixture from the uplands to the impact areas in bare
root form to ensure proper soils and planted evenly on eight foot spacing. If excavation of the plants is
deemed too destructive for the plant to have responsible chance of success, then new bare root seedlings
should be substituted. The quantity of plants per impact area indicated below is based on 510
seedlings/acre. All planted seedlings will be marked and tagged for monitoring purposes. Vegetation
success criteria will be the survival based on 360 seedlings /acre (70% vibrant survival) and included on
the chart below for each area. The hydrology success criterion will be considered the presence of field
hydrology indicators as defined by the 1987 US Army Corps of Engineers Wetland Delineation Manual
Filename: 090401 draft restoration plan.docx Page 1

and the 2008 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Atlantic and
Gulf Coastal Plain Region. The impact restoration area is currently and will remain in a partial
preservation easement in perpetuity.

Restoration Timelines
Upon approval from the Corps, remarking of the restoration extents and field stake out (including
elevations) will be made per the after the fact permit plan. Grading to original elevation and culvert
alterations will commence as soon as possible after Corps approval. Will request for Corps to verify
appropriate soils and concur with reestablished grades of restoration areas. Upon agreement, planting will
be done in early spring 2013 including sod for the adjoining uplands that are proposed as additional
impacts in the after - the -fact permit application. An as -built report will be completed and submitted to the
Corps within three weeks of completion of the restoration activities. Charles F. Riggs & Associates, Inc
will provide an as -built survey showing either elevation shots or cross sections documenting the grading
work as well as the planting layout.
Monitoring Plan
All restoration areas will be monitored for five years or until deemed successful. Annual monitoring
reports will be submitted to the Corps within three weeks of the anniversary of completion of the
restoration activities. Each report will consist of a simple narrative with vegetation and hydrology
analysis. Photographs will be included to document inherent conditions. COE data sheets will document
hydrology. In the event that hydrology and/or vegetative success criteria are not fulfilled, a contingency
plan will be implemented. The contingency plan will require consultation with the Corps if success is not
achieved during the monitoring period. Recommendations for further activities will be implemented and
monitored until hydrology and vegetative success criteria are achieved.

Re: The Reserve at Holly Ridge - wetland mitigation commitment letter SAW-2009-01959
Dear Ken Johnson,
The existing Hofmann Forest Wetland Mitigation Bank ( HFWMB) has several hundred non - riparian
credits available for sale.
The price per non - riparian credit is $48,311, so the purchase of 0.362 non - riparian credits will
require a payment of $17,488.58.
It is not clear from your message exactly how many non - riparian credits (not acres) you wish to
purchase - so I included the price for 0.362 credits as an example. Please check with your USACE
representative to determine that HFWMB credits will serve as acceptable mitigation for your
impacts.
If you should choose to purchase our credits please send payment along with your USACE Action
ID # (SAW- 2009 - 01959) and the name of the project to:
Mr. David L. Ashcraft
Executive Director, NC State Natural Resources Foundation, Inc.
3036 Biltmore Hall, Campus Box 8010
NCSU Campus Raleigh, NC 27695
...and we will send you a receipt verifying your purchase in the mitigation of your wetland impacts
and echoing the number and type of credits purchased, your USACE Action ID # and project name.
Please include your USACE Action ID (SAW- 2009 - 01959) along with the name of your project in
any further correspondence.
Thank you for your interest and cooperation and best of luck with your project,
Glenn
