REVISED Sediment Impact Delineation Report, Clean-up, and
Stabilization Plan
Wake County, NC
DWQ Project No. 06-0447
Dear Mr. Bertoncino:
Soil & Environmental Consultants, PA (S&EC) has been engaged by Olde Towne
Company, LLC to prepare a Sediment Impact Delineation Report and Clean-up Plan for
wetlands and open water (pond) sediment impacts which occurred within the referenced
project site as well as a stabilization plan for the impacted stream in Impact Area 1 to
prevent further erosion and sedimentation. These actions are in response to observations
made by the Division of Water Quality (DWQ) and United States Army Corps of
Engineers (USAGE) as sited in the Notice of Violations dated March 7, 2008 and April
14, 2008, and the Cease and Desist Letter (Action ID #200620287) dated November 2,
2007.
The purpose of this letter is to summarize our findings regarding sediment deposition that
has occurred onsite and describe in detail our plan for its clean-up and proper disposal as
well as stream stabilization in Impact Area 1.
Site Description
The project site, a proposed subdivision and golf course of approximately 547 acres, is
located east of Highway 440, along New Hope Road, between Poole Road and Rock
Quarry Road in the City of Raleigh in Wake County, North Carolina. A vicinity map is
provided in Figure 1.

Field Efforts and Onsite Observations
April 15, 2008
Project No. 4865.D1
Our observations and evaluations were focused on sediment clean-up deposition with in a
portion of previously delineated site wetlands and an open water pond. These areas were
impacted by sedimentation from site grading operations of upland areas. S&EC
performed an onsite inspection on March 21, 2008, and again on April 14, 2008. While
onsite we observed the characteristics of the site (including current grading and
stabilization operations), the surrounding area, verified surface and channel flow
conditions, observed wetland and open water sediment deposition, and observed existing
property boundaries, utilities, water conveyance structures, and existing erosion and
sediment control measures.
During our site visits, the impacted areas were traversed and the extent and severity of the
impacts was observed. While onsite, we identified, delineated (with sequentially lettered
and numbered flags), and GPS located the approximate boundaries of the flagged
sediment impacts.
From our site observations, sediment appears to have entered the impacted wetlands and
pond by the following primary means: 1) from streambank erosion of the impacted
stream channel, 2) at various locations onsite where existing Erosion and Sedimentation
(E&S) devices were overwhelmed, and 3) a lack of outlet protection.
A total of 0.92 acres (39,876 square feet) of wetlands and 0.11 acres (4,780 square feet)
of the pond were impacted by the deposition of sediment. This deposition varied from a
skim layer up to thicknesses of approximately fifteen (15) inches. Areas of sediment
accumulation in the wetlands and pond were flagged in the field and are shown on the
attached site maps (Sheets 1 through 4). Photos representative of our observations are
also provided for reference. Approximately 30 feet of the impacted stream is currently
experiencing accelerated erosion and is proposed for slight relocation and stabilization as
shown on Sheet 2.
Observed Sediment Deposition
Sediment deposition observed onsite varies considerably within the wetlands and open
water pond. For ease of evaluations we have divided observed sediment impacts into one
of three categories:
Category 1 (within the wetland area) -Sediment deposition in excess of
approximately two (2) inches in thickness which will require removal and proper
disposal.
Category 2 (within the wetland area) -Sediment deposition less than
approximately two (2) inches in thickness which will remain in place.
Category 3 (within the pond) -Open water sediment deposition varying from two
(2) to in excess of fifteen (15) inches in thickness which will require removal.
NOTE: Based on experience with similar sediment deposition and subsequent
Page 2 of 6

Olde Towne Subdivision
Soil & Environmental Consultants, PA
April 15, 2008
Project No. 4865.D 1
clean-up operations, it is our opinion that deposition layers less than
approximately two (2) inches in thickness should remain in place. Clean-up of
thin layers can result in damage to the underlying soils which will exceed the
temporary nature of localized thin layered deposition.
These impacted areas have been identified on the attached maps (Sheets 1 through 4).
Proposed Clean-up Operations
This clean-up plan has been prepared for the sole purpose of providing a systematic
approach to remove and/or stabilize in place sediment deposited into the wetland and
open water pond.
Based on our site observations and experience with similar projects, S&EC proposes the
following steps be performed to remove the existing sediment impacts onsite and reduce
the potential for future sediment impacts:
Step 1 Repair as necessary and augment existing site Erosion and Sediment
(E&S) control measures including silt fence, existing sediment traps,
sediment basins, and temporary stabilization measures. All
additional E&S control measures and repairs should beperformed /
installed in accordance with NCDENR approved standards and the
approved Erosion and Sediment Control Plan (by others).
Temporary and permanent seeding measures should be applied at the
earliest opportunity across exposed (non-actively graded) portions of
the site.
All existing and new E&S devices should be inspected and cleaned
out (sediment removed from upstream of the devices) as required.
Typically the frequency of inspection is weekly, and after each
rainfall event of 0.5 inches (or greater).
Step 2 To the extent, required by DWQ, manually remove excess sediment
in the wetlands (Category 1) as identified on the plan sheets.
Sediment will be excavated to a depth that reaches the approximate
natural grade (as determined by S&EC personnel).
All wetland excavation will be performed by hand. Excavation will
be performed with manual labor using shovels (flat head or "sharp
shooter") and 5 gallon buckets. Caution will be applied so as not to
disturb the original wetland surface.
Existing easements or site trails and roads will be used for vehicular
and mechanized equipment access to assist in mass sediment
removal. Where heavy equipment is used every effort will be made
to reduce the impact to the existing vegetation. No thinning or
clearing of vegetation will be performed. Delineated wetland areas
will not be trafficked with motorized equipment to perform clean-up

operations.
April 15, 2008
Project No. 4865.D1
Recovered sediment will be transported away from any channel,
wetland, or ponds and disposed of properly (in accordance with State
and local regulations).
Step 3 To the extent, required by DWQ, manually remove excess sediment
in the open water pond (Category 3) as identified on the plan sheets.
Sediment will be excavated to a depth that reaches the approximate
original pond bed (as determined by S&EC personnel).
Based on the estimated volume of sediment accumulated, impacted
areas within the open water pond will require mechanized equipment
to perform clean-up operations. Prior to excavation, the pond water
surface should be lowered (through pumping, siphon, or other
means) to a depth which will reasonably expose the deposited
sediment.
Excavated material shall not be double handled within the pond or
pond bed. Caution shall be applied so as not to disturb the original
pond bed. Where heavy equipment is used every effort will be made
to reduce the impact to the existing vegetation.
Recovered sediment will be transported away from any channel,
wetland, or ponds and disposed of properly (in accordance with State
and local regulations).
Step 4 Impacted wetland areas onsite will be seeded with a native wetland
seed mix following clean-up. The seed mix should include a
minimum of four species with a wetland indicator status of FAC,
FACW or OBL.
Species may include but are not limited to:
• Virginia Wild Rye (Elymus virginicus)
• Soft Rush (Juncus effusus)
• Sedge (Carex lurida, lupulina, or vulpinoidea)
• Woolgrass (Scirpus cyperinus)
• Cardinal Flower (Lobelia cardinalis)
• Lizard's T ail (Saururus cernuus)
Acceptable wetland seed mixes are commercially available that
include many more species and are designed for specific site
situations. Preference should be given to southeastern seed sources
and/or NC ecotype seeds in order to ensure seeds are adapted to the
local climate. Seed should be applied at a rate of 15 pounds per acre
(or as directed by the seed supplier) and covered with light straw
mulch.

Proposed Stabilization Operations
April 15, 2008
Project No. 4865.D1
The impacted stream will be temporarily relocated approximately 12 feet away from the
toe of slope of the existing stormwater pond embankment. The channel in this section
will be regraded to a more appropriate dimension. Rock toe protection will be placed on
the right bank of the stream (left and right are referenced while looking downstream) in
the section closest to the embankment. A boulder sill will be placed in the channel at the
channel invert elevation to prevent future headcuts. The exact extent and location of the
rock toe protection and sill will be determined by the engineer at the time of
Construction.
All disturbed areas will be seeded and mulched, the streambanks will be lined with coir
matting, and any other disturbed slope steeper than 3H:1 V will be lined with erosion
control matting. If there is flow in the channel during construction, a temporary coffer
dam above the proposed work and a temporary check dam below the proposed work will
be used to protect the downstream wetlands from sedimentation. Only the amount of
channel that can be stabilized in one day will be disturbed. A plan view of the proposed
stabilization is shown on Sheet 2 and details of the boulder structures and E&S controls
are shown on Sheets 5 and 6.
Clean-up and stabilization operations will be performed under the direct supervision of an
individual with a thorough understanding of the purpose and the delicate manner in
which manual methods should be performed. We understand that Olde Towne Company,
LLC will engage S&EC to provide periodic onsite observation of sediment clean-up
operations and provide guidance to the clean-up and stabilization contractor based on
experience and site conditions at that time.
Implementation Schedule
Clean-up and stabilization work should be executed immediately following the review
and approval of this plan by USACE and DWQ. Based on experience with similar
projects, we anticipate the clean-up work can be completed (barring any inclement
weather) within 30 days of the approval of this plan. Stream stabilization work will begin
immediately (baring any inclement weather) upon approval of the stabilization methods.
A notification should be submitted to DWQ and USACE following the completion of site
work.
Please contact me if you have any questions or comments regarding these
recommendations.
Sincerely,
uuw~
