Subject: Response to Notice of Violation
Dear Deborah:

&G a e
We are in receipt of your letter regarding the Notice of Violation that has been issued fortheTaylors Creek at
the Neuse project. Pursuant to this letter and our telephone conversation with you we are submitting this
written explanation of events that led to the issues cited in your letterand a plan for correctingthese items.
These items are as follows:
1. The total linear footage of streamside impacts associated with removal/cutting of riparian buffer
vegetation is forty feet (4o). Twenty feet (2o) of this impactwas required for installation of a sanitary
sewer line that connects the sewer system for the Taylors Creek project to the existing City of
Raleigh sewer main that runs alongthe adjacent greenway. It is our understanding that this amount
of buffer removal was allowed under our existing permits. Howeverthe stream channel and banks
were not permitted for permanent fill (rip-rap).
The remaining twenty feet (20) of streamside impacts was required for the installation of an
extension to the rip-rap dissipator that was installed forthe outlet of a waterquality pond thatwas
constructed as a part of the Taylors Creek project. This extension was installed as a means of
haltingthe erosion ofthat area which was downstream of the original dissipator. Upon completion
of the original dissipator it became evident that there was an erosion problem immediately
downstream. While reviewing this problem with the City of Raleigh Sedimentation Officer it was
agreed to by all parties that a larger dissipator was warranted
our plan is to remove the rip-rap from the channel, redefine the channel bottom and restore the
hydraulics to their original condition. We will stabilize the stream banks by seeding them with a
native grass and lining the banks with a non-biodegradable matting that will allow for seed
germination and plantgrowth while providingan anchorforthe roots of the vegetation once it has
been established. We will also restore that portion of the buffer that is outside of the 20' sewer

Subject: Notice of Violation
Taylors Creek at the Neuse
DWQ Project No. EXP 04-0359
SR 2517
Wake County
On January 13, 2005, Joe Albiston from the Raleigh Regional Office and Deborah Edwards
from the Central Office of the Division of Water Quality (DWQ), inspected a subdivision site,
located between SR 2517 and the Neuse River in Wake County.
During the site visit, the investigators took photographs and made observations of the
respective wetlands, stream and streamside/riparian buffer impacts. Specifically, the inspection
revealed unauthorized fill material placed in approximately 60 linear feet of stream and the cutting
and impervious fill in the riparian zone (within in Zone I and Zone 2).
Also noted during the January 13, 2005 site visit was a significant amount of sediment.
observed in the unnamed tributary to the Neuse River, a class C NSW water in the Neuse River
Basin. Approximately 575 linear feet of stream had sedimentation impacts that ranged in depths
from 6 inches to 2 feet. In addition, approximately 3100 square feet of riparian zone (Zone 1 and
Zone 2) was also observed to have sedimentation impacts.
A DWQ file review confirms that a 401 Water Quality Certification containing conditions was
issued for the subject subdivision. However, the site visit and file review confirmed that impacts to
the stream and riparian buffers were in excess of that authorized by the 401 Water Quality
Certification, and impervious fill had been installed in zone I and Zone 2. Asa result the following
below listed violations are noted or merit an additional information request: 1) Neuse River
Riparian Buffer violations, 2) 401 Water Quality Certification Conditions violations, 3) removal of
best usage and, 4) Settleable Solids Violation.

The Neuse River Basin is a river basin that is subject to riparian (streamside) buffer rules.
The purpose of these rules are to protect and preserve riparian buffers in the Neuse River Basin.
That is, these rule help to maintain the nutrient removal functions of the streamside areas
necessary to protect surface waters. Specifically, this Rule applies to the 50-foot wide riparian
buffers directly adjacent to surface waters (intermittent streams, perennial streams, lakes, ponds,
and estuaries). Further, the protected riparian buffer has two zones as follows: (a) Zone 1
[measured from stream bank landward for 30 feet] shall consist of a vegetated area that is
undisturbed except for uses provided for in Subparagraph (6) of 15A NCAC 2B .0233, and (b)
Zone 2 [the outer 20 feet, landward from the outer 30 foot edge of zone 1] shall consist of stable
vegetated area that is undisturbed except for activities and uses provided for in Subparagraphs (4)
and (6) of 15A NCAC 2B .0233.
The site visit and file review of this tract confirmed that a Pre-Construction Notification was
received for this project and riparian buffer impacts beyond that authorized in the 401 Water
Quality Certification and Riparian Buffer Authorization had occurred. Specifically, no request, or a
DWQ practical alternative determination, variance or authorization had been issued for these
additional impacts to the riparian zone. As a result the following riparian buffer rule violations are
noted:
Neuse River Buffer Rule15A NCAC 2B .0233 Deposition of fill, grading, grubbing and the
respective clearing of vegetation has occurred in the riparian zone, a violation of the requirement
that Zone I and Zone II consist of a stable, vegetated area that is undisturbed except for activities
and uses provided for in Item (6) of the Rule.
Item 2.401 Water Quality Certification Conditions
On March 26, 2004, a 401 Water Quality Certification (DWQ Project No. EXP 04-0359) was
issued for the subject tract. The following bullets are issues that coincide to conditions within the
Certification:
Condition number 3 - No waste, spoil, solids or fill of any kind shall occur in wetlands, waters
or riparian areas beyond the footprint of the impacts depicted in the Preconstruction Notice
Application. All construction activities, including the design, installation, operation, and
maintenance of sediment and erosion control Best Management Practices, shall be performed
so that no violations at state water quality standards, statutes, or rules occur.
Item 3. Preclusion of Best Usage
A DWQ site visit and file review confirmed that approximately 60 linear feet of stream
impacts occurred to an unnamed tributary to the Neuse River. This impact occurred by the
placement of a rip-rap dissipater in the stream. These impacts represent a removal of best usage.
Specifically, 15A NCAC 213 .0211(2) states that the preclusion of best usage; which include
aquatic life propagation, biological integrity, wildlife, and secondary recreation, and agriculture
represent a water quality standard violation.
Item 4. Settleable Solids Violation:
The deposition of sediment was observed impacting approximately 575 linear feet of
stream. The sediment amounts/depths typically ranged from 6 to 12 inches; however, depths
greater than 24 inches were commonly encountered in portions of the stream segment. These
impacts represent a standard violation for settleable solids. 15A NCAC 2B .0211(3)(c) which
respectively states the following:

15A NCAC 2B .0211(3)(c) "Floating solids, settleable solids, sludge depositions: only such
amounts attributable to sewage, industrial waste or other waste as will not make the water
unsafe or unsuitable for aquatic life and wildlife or impair the waters for any designated
uses."
This Office requires that violations, as detailed above, be abated immediately. Also please
note, these violations and any future violations are subject to civil penalty assessment of up to
$25,000.00 per day for each violation. This Office requests that you respond to this letter, in
writing, within 20 days of receipt of this Notice. Your response should address the following items:
1. Please provide a map depicting the total linear footage of streamside impacts associated
with removal/cutting of riparian buffer vegetation. Also, please clearly explain how and why
the streamside areas were cut/thinned. In addition, please provide a map depicting the
total area of streamside impacts associated with the sediment that overtopped the sediment
fence and remains in the riparian area.
2. A Restoration Plan for this site should be submitted to Ms. Deborah Edwards of the
401 Oversight/Express Permitting Unit=. Central Office. (2321 Crabtree Blvd.,
Parkview Building, Raleigh, NC 27604-2260) for our review. Copies of this plan
should be sent to letterhead address: and. you; should contact the Division of Land
Resources (or the appropriate delegated program) to ensure that your restoration
plans are in compliance with the requirements of the Division of Land Resources.
This restoration plan must include the following:
a.) A riparian restoration planting plan. This planting plan must be developed such that, at
least two native tree species are to be planted at a density sufficient to provide 320
trees per acre at maturity. This density can be achieved by planting approximately 436
(10x10 feet spacing) to 681 (8x8 feet spacing) trees per acre. Please indicate in your
response a schedule with dates detailing when this will be accomplished.
b.) A riparian restoration plan for the removal of the sediment within the riparian area. This
should include how the sediment will be removed and where the sediment will be taken.
Please be reminded that no mechanized equipment is allowed in the riparian area.
3. Clearly detail why the project, depicted in the Pre-construction Notification Application dated
March 19, 2004 and the respective 401 Water Quality Certification issued March 26, 20041
has been modified from DWQ's earlier approval. That is, the enlarged rip-rap dissipater
that has been placed in the subject stream and the riparian buffer, zones 1 and 2.
4. Please clearly indicate in your response what efforts you have taken to temporarily
stabilize/abate the impacts associated with the land disturbance such.that the settleable
solids impacts to waters are stemmed. This issue should be addressed immediately in
order to help avoid additional stream standard violations.
5. Provide records or information of any off-site sedimentation that has occurred and include a
respective explanation as to the measures taken to prevent future releases and measures
taken to clean up the sediment that has left the disturbed limits of your project.
6. You should also explain how you propose to prevent these problems from reoccurring with
this project and with future projects.

7. You must restore the impacted stream segments. You must submit a stream restoration
plan to the Division of Water Quality. Copies of this plan should be sent to letterhead
address. In addition, you should contact the Division of Land Resources (or local delegated
program) to ensure that your restoration plans are in compliance with the requirements of
the Division of Land Resources. This restoration plan must include the following:
a. You must remove the accumulated sediment from the stream. It is
recommended that you use hand labor (buckets, shovels and wheelbarrows)
to remove deposited sediment from the stream channel. The sediment,
should be removed from the channel, taken to high ground and stabilized.
b. Please provide a sediment removal plan for review and approval by the
Division of Water Quality. This plan should include a schedule with dates
that indicate when you propose to complete the removal of the sediment.
Your plan must also include a diagram of the stream channel that shows
those areas where you propose to remove sediment. This map must also
indicate the amount of sediment accumulated in the channel prior to
restoration efforts.
c. It is recommended that you contact Deborah. Edwards of this office by phone
(919-733-9502) to receive guidance/instructions for immediate clean up
efforts necessary to help stem.the likelihood,ofadditional surface water
standard violations.
Thank you for your attention to this matter. This Office is considering sending a
recommendation for enforcement to the Director of the. Division of Water Quality regarding these
issues and any future/continued violations that may be encountered. Also, your above-mentioned
response to this correspondence will be considered in this process. Should you have any
questions regarding these matters, please contact Deborah Edwards at [phone].

easement. We will accomplish this by planting a mixture of native trees at a density that will restore
this area to its preconstruction condition. Please review the attached map for further details.
2. The total linear footage of strearnside impacts associated with the sediment that overtopped the silt
fence is approximately 0.25 acres of buffer and approximately goo' of stream channel. These
deposits were released duringa high intensity rain duringwhich a diversion ditch was blown outand
the silt fence, which was installed behind the ditch as a secondary protection, was overtopped.
These deposits will be removed from the buffer and the stream channel with the use of manual labor
and personnel that are trained to complete such cleanup workwhile havingminimal disturbanceto
the existing ecological zones that are present in this area. The silt that is removed from these areas
will be taken back into the project's area of gradingwhere it will be dispersed evenly and stabilized
with seeding. No machines will be used within the buffer areas or outside of the. project's limits of
disturbance.
The crews will be mobilized on Monday 2/28/05 to get started on removingthe silt deposits from the buffer
and stream channel. Asecond group will be working atthe same time to remove the fill from the stream below
the pond and begin restoringthe bufferand stream channel in this area. We expect thatthe silt deposits will
be removed by 3/10/05. We expect that the buffer restoration will be complete by 3/18/05. Please note that
both of these schedules will be strictly dependant on the forthcoming weather. We believe that working in
these areas immediately after a rain event will cause furtherdamage and therefore we will monitorthe ground
water conditions regularly and let them dictate which dais are suitable to work.
The construction of this site has now progressed to pavement and final grading. The permanent storm
drainage is now functional and a large portion ofthe site has been seeded. We believethat all ofthiswill help
prevent further issues on this site. We trust that you will concur with this belief during your follow up
inspections for this project.
Should you require any further assistance with this matter please do not hesitate to contact Dell Ray
Investments or us at anytime. Thank you for your continued assistance with this project.

Engineers (USACE).
This letter shall also act as your approved Authorization Certificate for impacts to the protected riparian buffers per 15A
NCAC 2B .0233. In addition, you should obtain or otherwise comply with any other required federal, state or local
permits before you go ahead with your project including (but not limited to) FEMA, Erosion and Sediment Control, Non-
discharge and Water Supply Watershed Protection regulations. Also, this approval will expire when the accompanying
404 permit expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your
project, you must notify us and you may be required to send us a new application. If the property is sold, the new
owner must be given a copy of this Certification and approval letter and is thereby responsible for complying with all
conditions. If total fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of stream,
compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you
must follow the conditions listed in the attached certification and any additional conditions listed below.
Conditions of the Certification:
1. Erosion and sediment control practices must be in full compliance with all specifications governing the
proper design, installation and operation and maintenance of such Best Management Practices in order
to protect surface waters standards:

a. The erosion and sediment control measures for the project must be designed, installed, operated,
and maintained in accordance with the most recent version of the North Carolina Sediment and
Erosion Control Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control
measures must be such that they equal, or exceed, the requirements specified in the most recent
version of the North Carolina Sediment and Erosion Control Manual. The devices shall be
maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including
contractor-owned or leased borrow pits associated with the project.
c. If this project requires borrow pit sites, the erosion and sediment control measures must be
designed, installed, operated, and maintained in accordance with the most recent version of the
North Carolina Surface Mining Manual.
d. Any reclamation measures and implementation must comply with the reclamation in accordance
with the requirements of the Sedimentation Pollution Control Act.
2. The outside buffer, wetland or water boundary as well as along the construction corridor within these
boundaries approved under this Certification shall be clearly marked by orange fabric fencing for the
areas that have been approved to infringe within the buffer, wetland or water prior to any land disturbing
activities to ensure compliance with 15A NCAC 213.0250.
2. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum
extent practicable. If placement of sediment and erosion control devices in wetlands and waters is
unavoidable, they shall be removed and the natural grade restored within six months of the date that
the Division of Land Resources has released the project.
3. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the
footprint of the impacts depicted in the Preconstruction Notice Application. All construction activities,
including the design, installation, operation, and maintenance of sediment and erosion control Best
Management Practices, shall be performed so that no violations of state water quality standards, statutes,
or rules occur.
4. Stormwater management structures shall be constructed and maintained according to the plans
submitted in the March 19, 2004 application.
5. All stormwater shall be directed as diffuse flow at non-erosive velocities through the protected stream
buffers and will not re-concentrate before discharging into the stream as identified within 15A NCAC 2B
.0233(5).
6. During the construction of the project, staging of equipment of any kind is not permitted in waters of the
State, or protected riparian buffers.
7. The dimension, pattern, and profile of the stream, above and below the crossing, should not be
modified by widening the stream channel or reducing the stream depth. Disturbed floodplains and
streams should be restored to natural geomorphic conditions.
8. Where practicable, culverts that are less than 48-inch in diameter should be buried to a depth equal to
or greater than 20% of their size to allow for aquatic life passage. Culverts that are 48-inch diameter or
larger should be buried at least 12 inches below the stream bottom to allow natural stream bottom
material to become established in the culvert following installation and to provide aquatic life passage
during periods of low flow. This may require increasing the size of the culvert to, meet flow conveyance
requirements. All waters must flow through without freefalling or damming on either end of the culverts
during low flow conditions, to maintain aquatic life and/or fish passage.
9. Any riprap used must not interfere with aquatic life passage during low flow conditions.
10. If concrete is used, work must be accomplished so the wet concrete does not contact the stream water.
This will lessen the chance of altering the stream's water chemistry and causing a fish kill.
11. Heavy equipment must be operated from the banks rather than in the stream channel in order to
minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream.
Dell Ray Investments

12. The presence of equipment in the channels must be minimized. Under no circumstances must rock,
sand or other materials be dredged from the wetted stream channel under this authorization, except in
the immediate vicinity of the culverts.
13 During the construction of the project, no staging of equipment of any kind is permitted in waters of the
U.S., or protected riparian buffers.
14. The applicant and/or authorized agent shall contact DWQ when construction commences.
15. Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer
Rules, and any subsequent modifications, the applicant is required to return the attached certificate of
completion to the 401 /Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service
Center, Raleigh, NC, 27699-1650.
Violations of any condition herein set forth may result in revocation of this Certification and may result in criminal
and/or civil penalties. This Certification shall become null and void unless the above conditions are made conditions of
the Federal 404 and/or coastal Area Management Act Permit. This Certification shall expire upon expiration of the 404
or CAMA permit.
If you do not accept any of the conditions of this Certification (associated with the approved wetland or stream
impacts), you may ask for an adjudicatory hearing. You must Act within 60 days of the date that you receive this letter.
To ask for a hearing, send a written petition, which conforms to Chapter 150B of the North Carolina General Statutes
to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its
conditions are final and binding unless you ask for a hearing.

RE: Request for NWP 12, NWP 39, and Buffer Compliance
Taylors Creek at the Neuse MAR 1 9 2004
Raleigh, Wake County, North Carolina
Dear Ms. Edwards and Ms. Burdette:
On behalf of Dell Ray Investments, LLC (Attn: R.D. Scales), we hereby request
authorization from the US Army Corps of Engineers to use Nationwide Permits 12 and
39 to cover impacts to streams and buffers (see attached overall map). We also request
written concurrence from the North Carolina Division of Water Quality that the project
complies with the Neuse Buffer Rules for impacts associated with the proposed road
crossing and utility lines. A Pre-construction Notification Application (PCN) is attached,
which includes an agent authorization form.
S&EC delineated the wetlands and stream channels located on the property so that plans
could be developed that avoid and minimize impacts to the maximum extent practicable.
Ms. Debbie Edwards of the Department of Water Quality has been on site to confirm the
beginning of the buffered channels. Ms. Edwards' determination is discussed in a copy
of her attached letter (NBRRO 04-070) and is reflected on the impact maps. The wetland
delineation has not yet been approved by the USACE but has been sent to the USACE for
their approval.
The purpose of this project is to construct a residential subdivision that will meet the
demand for housing in this area. In order to provide the infrastructure for the proposed
subdivision (i.e. roads, water, and sewer), impacts to the riparian buffers, wetlands and
wetlands were required. Specifically, existing road stubs are located off-site adjacent to
the property. The location of the current road south of the property dictates the vicinity
in which the proposed road can be located. The stream crossing was located at a break in

the Neuse River buffer to minimize buffer impacts while allowing inlerconnectivity
between the northern and southern sections of the property. The proposed impacts due to
road construction include 112 linear feet of intermittent channel, 0.0929 acre (4047 ft2)
and 0.25 acres of riparian buffer. In addition, the proposed sewer outfalls will impact 20
linear feet of intermittent channel and 0.12 acres of riparian buffer. Please note that the
proposed temporary parallel impacts to zone 2 of the buffer were unavoidable due to the
location of the tie in points (i.e. an adequately sized man-hole). For additional
information please refer to the attached letter from Withers and Ravenel detailing the
justification for the road crossing and the proposed sanitary sewer alignment. The total
amount of wetland impacts is approximately .0042 acre.
The impervious surface area for the project is 25.7% and therefore does not require DWQ
to preapprove the stormwater plan, however, the stormwater plan is attached. A copy of
the maintenance agreement for the stormwater pond is also attached.
The USACE's current policy requires applicants to avoid and minimize wetland and
stream channel impacts to the maximum extent practicable and may require
compensatory mitigation to offset unavoidable losses for impacts to forested wetlands.
The applicant requested a detailed delineation of wetlands present on the site prior to
developing construction plans in order to avoid impacts. Because a stream crossing is
necessary in order to connect portions of the property, we do not believe mitigation
should be required. However, if mitigation is required we propose payment to the EEP.
NC-DWQ's current policy does not require buffer mitigation for perpendicular impacts
that total less than 1/3 acre or for impacts resulting from utility lines that are less than 40'
wide. Because the proposed impacts are below these thresholds we do not believe buffer
mitigation should be required for the proposed road.
Please call or email me at SClarkPSandEC.com if you have any questions.
Sincerely, Sean Clark

Attach a vicinity map clearly showing the location of the property with respect to local
landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no larger than I1 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.

5. Site coordinates, if available (UTM or Lat/Long): Zone 17, 722340'E, 3962300MN
(Note - If project is linear, such as a road or utility line, attach a sheet that separately lists the
coordinates for each crossing of a distinct waterbody.)
6. Property size (acres): +/- 27 acres
7. Nearest body of water (stream/river/sound/ocean/lake): UT to Neuse River
8. River Basin: Neuse
(Note - this must be one of North Carolina's seventeen designated major river basins. The
River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.)
9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: This site is partially forested and has been logged in the
past. This site is currently undeveloped and surrounded by residential subdivisions.
Page 2 of 9
10. Describe the overall project in detail, including the type of equipment to be used:
The proposed project is a single-family residential subdivision with the typical utilities (i.e.,
sewer, water, electric etc.) One intermittent stream and its associated riparian buffer will be
impacted to provide a road to connect the north and south end of the proposed Taylors Creek
subdivision (NWP 39). Also the intermittent stream and its associated riparian buffer will be
temporarily impacted to provide a sewer connection to the proposed subdivision (NWP 12).
Typical excavating and grading equipment will be used during construction activities.
11. Explain the purpose of the proposed work: The purpose for this subdivision is to provide
additional housing for the area. The road crossing of the intermittent stream is required to
connect the northern and southern portions of this property. The road location is dictated by
the existence of two existing road stubs on adjacent properties. The utility crossing is
required to supply a sewer service to the property.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date pen-nits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules.
S&EC delineated the wetlands and stream channels located on the property so that plans could
be developed that avoid and minimize impacts to the maximum extent practicable. Ms. Debbie
Edwards of the Department of Water Quality has been on site to confirm the beginning of the
buffered channels. Ms. Edwards' determination is discussed in a copy of her attached letter
(,NBRRO 04-070) and is reflected on the impact maps The wetland delineation has not yet been
approved by the USACE but has been sent to the USACE for their approval.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
There are no proposed future impacts for this site
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. The applicant must also provide
justification for these impacts in Section VII below. All proposed impacts, permanent and temporary,
must be listed herein, and must be clearly identifiable on an accompanying site plan. All wetlands and
waters, and all streams (intermittent and perennial) must be shown on a delineation map, whether or not

* List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging,
flooding, drainage, bulkheads, etc.
5. 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.): NA
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): NA
Size of watershed draining to pond: NA Expected pond surface area: NA
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.
The roadway crossing is required to connect the two portions of the property. Without the
proposed crossing the resulting cul-de-sac would exceed the City of Raleigh's allowed cul-de-
sac road length (refer to attached justification letter) To further reduce and minimize proposed
impacts the road crossing has been placed near a break in the Neuse River Buffer. The proposed
sewer main must tie to an existing manhole that exists within the Neuse River Buffer. The
proposed sewer main must travel parallel within zone 2 of the Neuse River Buffer until a proper
connection can be made(refer to justification letter). Parallel impacts to Zone 1 of the riparian
buffers were avoided.
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.
Page 5 of 9
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, 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 NCWRP 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, available at
h!Ltp://h2o.enr.state.nc.us/ncwetlands/stnngide.htrnl.
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 should be required because permanent impacts to wetlands are less than
1/10 acre and no perennial channel impacts are proposed.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet): NA
Amount of buffer mitigation requested (square feet): NA
Amount of Riparian wetland mitigation requested (acres): NA
Amount of Non-riparian wetland mitigation requested (acres): NA
Amount of Coastal wetland mitigation requested (acres): NA

Raleigh, Wake County, NC
Dear Mr. Peffer:
On January 15, 2004, 1 conducted a site visit of features A and B involved in the above
referenced project as identified on the attached figures 1 and 2. It was determined that the features
shown on the Wake County Soil Survey, but absent on the USGS Raleigh East, NC Quad map
could potentially be subject to protection under the Neuse River Basin: Nutrient Sensitive Waters
Management Strategy; Protection and Maintenance of Existing Riparian Areas, Administrative Code
T1 5A: 0213.0233 (NCAC .0233).
The Division of Water Quality (DWQ) has determined that the surface waters labeled
as "A and B " on the attached maps are subject to the Neuse Buffer Rule. Feature A has
been delineated and flagged, the origin has been flagged as A10, this feature is subject
through to flag #1000, this feature then falls apart and is not subject until flag #1001. At flag
#1001, feature A is again subject, goes off property and then through a modified channel
along the greenway (on property), is piped under the greenway and connects to the Neuse
River. Feature B (Neuse River) was not contested, therefore it is subject. This feature and its
associated buffers should be identified on any future plans for this property. The owner (or future
owners) should notify the DWQ (and other relevant agencies) of this decision in any future
correspondences concerning this property. This on-site determination shall expire five (5) years
from the date of this letter.
Landowners or affected parties that dispute a determination made by the DWQ or Delegated
Local Authority that a surface water exists and that it is subject to the buffer rule may request a
determination by the Director. A request for a determination by the Director shall be referred. to the
Director in writing, c/o John Dorney, DWQ Wetlands/401 Unit, 2321 Crabtree Blvd., Raleigh, NC

Individuals that dispute a determination by the DWQ or Delegated Local Authority that
"exempts" a surface water from the buffer rule may ask for an adjudicatory hearing. You must act
within sixty (60) days of the date that you receive this letter. Applicants are hereby notified that the
sixty (60) day statutory appeal time does not start until the affected party (including downstream and
adjacent landowners) is notified of this decision. DWQ recommends that the applicant conducts
this notification in order to be certain that third party appeals are made in a timely manner. To ask
for a hearing, send a written petition, which conforms to Chapter 150B of the North Carolina General
Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. This
determination is final and binding unless you ask for a hearing within sixty (60) days.
This letter only addresses the applicability of the Neuse Buffer Rules. For information
relevant to 401 Water Quality Certifications, wetlands and other impacts to "waters of the state",
please contact the Central Office at 733-1786. (Note: if a 401 Water Quality Certification is needed,
please be reminded not to begin your project until the certification has been received.) Thank you
for your attention to this matter and if this office can be of any assistance or if you have additional
questions, please do not hesitate to contact us.

RE: Taylors Creek at the Neuse
W&R Project No. 203233
Dear Kevin:
We are writing this letter to you in response to your questions related to the submittal to the. NC Division
of Water Quality (DWQ) and US Army Corps of. Engineers (USACE) for the above referenced project. Your
questions and our responses are as follows:
Why does the roadway need to cross the Neuse River Buffer in the eastern portion
of the property rather than crossing west of the buffer? The roadway must cross
the Neuse River Buffer in the eastern portion of the tract, since crossing on the
western side of the property would require a long cul-de-sac to access the lots
north of the buffer. The City of Raleigh limits dead end streets in residential areas
to a maximum of 800 feet. If the roadway crossed west of the Neuse River Buffer,
a cul-de-sac length of approximately 1200 feet would be required, much higher
than the maximum length allowed. Also, please note the road crossing has been
placed nearthe break in the Neuse River Bufferto further reduce. impacts.
2. Why does the sewer main require bends within Zone 2 of the Neuse River Buffer?
The proposed sewer main must tie to an existing sewer manhole that lies within
the Neuse River Buffer. The existing sewer main is 54" in diameter, therefore, the
sewer must tie into the western. side of the manhole to prevent a conflict between
the proposed sewermain and the existing sewermain running north/south.
Therefore, the proposed sewer parallels within Zone 2 of the NRB main until an
appropriate angle into the existing manhole can be achieved.
We trust this letter clarifies the design. used for the road and utility crossings on this project. Please feel
free to forward this information to the. Division of Water Quality for their review. If you have any further
questions or require additional information, please. feel free to give us a call.

EXTENDED DRY DETENTION BASIN
OPERATION AND MAINTENANCE AGREEMEN
The dry detention basin system is defined as the dry detention basin, pre-treatment cluding forebays and the
vegetated filter if one is provided.
Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the dry detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice on the skimmer of any obstructions such that drawdown of the temporary
pool occurs within 2 to 5 days as designed.
2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow
vegetative cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the dry detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed
of in an appropriate manner and shall be handled in a manner that will not adversely impact water quality
(i.e. stockpiling near a detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading.
When the sediment depth reads 2.0 feet in the main pond, the sediment shall be removed.
When the sediment depth reads 0.7 feet in the forebay, the sediment shall be removed.

STORMWATER MANAGEMENT MANUAL
TAYLORS CREEK AT THE NEUSE, PHASES 1 & 2
I. INTRODUCTION
Taylors Creek at the Neuse, Phases 1 & 2 is a single-family development located in eastern Raleigh,
North Carolina. The project consists of building 69 single family homes on 27.01 acres. The plan was
administratively approved by the City of Raleigh under subdivision file number S-116-03.
This stormwater management manual was developed to show compliance with the City of Raleigh's
stormwater management regulations as outlined in Part 10, Chapter 9 of the Raleigh city code. The
two primary stormwater regulations that must be complied with are nitrogen reduction and runoff
controls.
11. NITROGEN REDUCTION
New development must adhere to a nitrogen reduction regulation that imposes a nitrogen load limit on
new development of 3.6 pounds per acre per year (lb/ac/yr). This regulation is specified in Raleigh
code section 10-9022. Nitrogen loading from new development that exceeds this performance
standard may be offset by payment of a fee to the Wetlands Restoration Fund, provided that no new
residential development can exceed 6.0 lb/ac/yr.
To achieve compliance, we are proposing to use one stormwater management device, a dry detention
pond, which is located on-site in the mid eastern portion of the property. The dry pond does not provide
any reduction in nitrogen loading; however, it does provide reduction in peak runoff characteristics that will
be discussed in the following section.
Nitrogen reduction calculations summarized below, indicate that the average nitrogen-loading rate that can
be attained is 3.68 lb/ac/yr. Since the loading rate is higher than the 3.6 Ib/ac/yr prescribed by the
ordinance, a fee in lieu payment in the amount of $712.80 must be paid to the Wetlands Restoration fund
to offset the difference. Detailed calculations are provided in the Appendices of this document.

Est. offset payment to get nitrogen loading to 3.6 Ibs/ac/yr ($330 per lb./ac.) = $712.80
RUNOFF CONTROLS
New developments must comply with runoff controls that require the peak stormwater runoff leaving
the site for the two-year storm event to be no greater for the post-development conditions than the pre-
development conditions. This regulation is specified in Raleigh city code section 10-9023.
The Neuse River forms the eastern boundary of the subdivision. Thus, the site drains either directly to
the Neuse River via sheet flow, or drains to a small tributary that empties into the Neuse at the eastern
property boundary.
METHODOLOGY
This stormwater study was conducted using the natural drainage features as depicted bythe Wake County
aerial topographic information, field survey and proposed development within the Taylors Creek at the
Neuse subdivision. An extended dry detention pond is proposed in the eastern portion of the site to
provide 2-year peak attenuation for the contributory drainage area, as well as the rest of the site.
Approximately 11.8 acres of the site drains to the pond, as well as 3.7 acres of off-site area. The
remaining 15.2 acres of the project area sheet flows off the site in various directions (i.e. "untreated" area).
However, approximately 8 acres of the "untreated" area is open space either in Neuse River Buffer or the
floodplain area along the Neuse River. Therefore, the hydrologic model takes into account the off-site
area draining to the pond and the untreated area on the site to determine whether or not the entire site
meets the 2-year peak attenuation requirement.
The scope of work included the following analyses:
Hydrology
¦ Simulation of 2-year, 10-year and 100-year rainfall events for the Raleigh area
¦ Formulation of 2-year, 10-year and 100-year flood hydrographs for pre- and post-development
conditions
Hydraulic
¦ Routing the 2-year, 10-year and 100-year flood hydrographs for post development runoff
through the proposed dry pond
The results of the hydrology analyses are used in the hydraulic analyses. The routing analysis
requires the development of stage-storage and stage-discharge functions for the proposed pond. The
rainfall/runoff hydrographs, stage-storage and stage-discharge functions have been combined to
create a routing computer simulation model using Haestad Methods PondPack v9.0 software. This
PondPack model was then used to assess the impact of the peak discharges for the design rainfall
events. The PondPack computer model analyses results are provided as Appendix A of this report.
HYDROLOGY
The SCS Method was used to develop runoff hydrographs for the Type II, 24-hour duration, 2-year, 10-
year and 100-year storm events for the Raleigh area. This method requires three basic parameters: a
curve number (CN), time of concentration (tc), and drainage area. Curve numbers are based on soil type
and land use. Soil types were delineated from the Soil Survey of Wake County, North Carolina (November
1970). Land use was based on aerial photography, Wake County tax parcel data and field observation.
Time of concentrations were calculated using the methods described in the SCS publication "Urban
Hydrology for Small Watersheds, TR-55 and were based on field survey and Wake County GIS
topography. A 5-minute time of concentration was used for the post-development drainage area to the
pond based on the piped stormwater conveyances. Drainage areas were delineated from field surveyed
2
topography, Wake County GIS topography and proposed grading for the site. A drainage area delineation
map is included as part of this report.
HYDRAULICS
Computer simulated reservoir routing of the 2-year, 10-year and 100-year storm events utilize stage-
storage and stage-discharge functions. Stage-storage functions were derived from the proposed grading
for the dry pond as shown on Sheet 3 of the construction drawings. A non-linear regression relation for
surface area versus elevation was derived forthe dry pond. This relation estimates the incremental volume
of the basin to the stage or elevation of the basin. Stage-discharge functions were developed to size the
outlet structure for the dry pond to meet the design requirements.
CONCLUSIONS
The proposed dry pond is designed to attenuate the 2-year post-development peak discharge rate
from the site to less than or equal to pre-development conditions. The PondPack model accounts for
off-site drainage area to the pond that was passed through the pond but not accounted for in the peak
attenuation, as well as the "untreated" area of the site that does not drain to the pond. Peak
attenuation results are summarized in Table 1 below. In addition, the proposed dry pond is designed
to pass the 100-year storm event through the primary riser/barrel structure with approximately 0.5 feet
of calculated freeboard.

OPERATIONS AND MAINTENANCE
MAINTENANCE OF EMBANKMENTS
A. Vegetation
? The embankment has a ground cover of fescue, which if properly maintained will prevent
erosion of the embankment and provide an easy surface for inspection. Grass should be
fertilized every October and April.
? Re-Seeding - Periodically re-seeding may be required to establish grass on areas where
seed did not germinate or has been destroyed. Before seeding, fertilizer (12-12-12) should
be applied at a minimum rate of 12 to 15 pounds per 1,000 SF. The seed should be evenly
sewn at a rate of three pounds per 1,000 SF. The seed should be covered with soil to the
depth of approximately 1/4". Immediately following the seeding, the area should be
mulched with straw.
? Trees and Shrub - Trees, shrubs and other landscape vegetation should be permitted only
as shown on the approved planting plan. Trees should be discouraged from growing on
the earth embankment.
? Mowing - Grass mowing, brush cutting and removal of weed vegetation will be necessary
for the proper maintenance of the embankment. Embankment slopes should be mowed
when the grass exceeds 8" in height. Acceptable methods include the use of weed whips,
power brush cutters, or mower.
B. Erosion
Erosion occurs when water concentrates causing failure of the vegetation orwhen vegetation dies
and sets up the environment for rill erosion and eventually gullies from the stormwater runoff. The
earth embankment (dam) should be inspected for these types of erosion. Proper care of vegetative
areas that develop erosion is required to prevent more serious damage to the embankment. Rills
and gulleys should be filled with suitable soil compacted and then seeded. Re-seeding methods
described in Section IV-A should be used to properly establish the grass surface. Where eroded
areas are detected, the cause of the erosion should be addressed to prevent a continued
maintenance problem. Frequently, problems result from the concentration of runoff to one point of
the embankment crest (top of dam) instead of a uniform distribution of runoff. This can be
corrected by reshaping the crest to evenly distribute the runoff to areas that are not experiencing
erosion problems. The top of the dam should not be allowed to be used for pedestrian or bicycle
traffic.
? Abutments Areas - The abutment is the line formed where the embankment fill comes into
contact with the existing slope. Runoff from rainfall concentrates in these gutter areas and can
reach erosive velocities because of the steep slopes. If a normal stand of grass cannot be
maintained on the abutments, additional measures may be needed such as jute matting to
provide for the establishment of a good ground cover.
? Upstream embankment slope - Erosion problems can develop on the upstream face of the
dam due to the fluctuation of water level in the ponds. This is a result of a combination of wave
actions and ground saturation, which occurs from the elevated water levels. The erosion
generally occurs as the water level falls and the saturated ground becomes subjected to the
wave action. If erosion becomes a problem, it may necessitate the installation of a stone
armoring along the zone subject to fluctuating water level. This would consist of 18" of NCDOT
Class B stone for erosion control underlain with a geotextile filter fabric. It should be centered
6
at the point of the erosion problem and covering an area two feet above and below the
approximate center of the eroded area.
C. Seepage
Due to the fact that there is no "permanent' impoundment level of the pond, seepage should not
be expected on the downstream slope of the embankment. A cursory inspection of the
downstream face of the dam should be made for completeness of the inspection. Seepage may
vary in appearance from a soft wet area to a flowing spring. It may show up first as only an area
where the vegetation is more lush and darker green. Cattails, reeds, mosses and other marsh
vegetation often become established in a seepage area. The downstream abutment areas where
the embankment fill and natural ground interface are very common locations for seepage. Also the
contact between the embankment and the spillway is a common location, which is generally
attributed to poor compaction at the point of contact. Slides may result from excessively saturated
embankment slopes. The natural foundation area immediately downstream of the dam abutment
should also be inspected to ensure that "piping" is not occurring underneath the embankment.
"Piping" may appear as a "boil" evident as spring carrying soil. The soil usually deposits around the
boil area and is evident by the sedimentary deposits accompanying it. Seepage can also occur into
the spillway conduit through cracks in the pipe or improperly sealed joints. This type of seepage
can be detected by observing the conduit when the water level is high. The movement of the water
itself is not dangerous but if soil particles are being carried with it, then it can create a shortcut for
the piping of soil. This might show up on the upstream face of the embankment roughly along the
line of the conduit itself.
D. Cracks, Slides, Sloughing, and Settlement
? Cracks - The entire embankment should be inspected for cracks. Short, isolated cracks are
usually not significant, but larger, well-defined cracks (wider than '/") indicate a serious
problem. There are two types of cracks: transverse and longitudinal.
¦ Transverse cracks appear crossing the embankment and indicated difference of
settlement within the embankment. These cracks provide avenues for seepage and
piping.
¦ Longitudinal cracks run parallel to the embankment and may signal the early stages of
a slide. In recently built structures, these cracks may be indicative of pour compaction
or pour foundation preparation resulting in consolidation after construction.
? Slides -Slides and slumps are serious threats to the safety of an embankment. Slides can
be detected easily unless obscured by vegetation. Arch shaped cracks are indications that
slides are slipping or beginning to slip. These cracks soon develop into large scarps in the
slope at the top of the slide.
? Settlement - Settlement occurs both during construction and after the embankment has
been completed and placed in service. To a certain degree this is normal and should be
experienced. It is usually the most pronounced at the location of maximum foundation
depth or embankment height. Excessive settlement will reduce the free board (difference in
elevation between the water surface and the top of the dam). Any area of excessive
settlement should be restored to original elevation and condition to reduce the risk of
overtopping. A relatively large amount of settlement (more than 6") within a small area
could indicate serious problems in the foundation or perhaps the lower part of the
embankment. Settlement accompanied by cracking often proceeds failure.
What to do if seepage, cracks, slides or settlement are detected:
? Failure of the embankment could result if any of the above items are detected. A
7
geotechnical or civil engineer should be consulted regarding the origin of these
problems and for the assessment of the appropriate solutions for correcting them.
E. Rodent Control
Generally in this urban environment, rodents are not a problem. Rodents such as ground hogs,
muskrats and beavers are attracted to dams and reservoirs and can be quite dangerous to
structural integrity and proper performance of the embankment and spillway. Groundhog and
muskrats thrive on burrowing in the manmade earth embankments, which become pathways for
seepage. In the event, that burrows are detected within the dam then the rodents should be dealt
with by removal.
MAINTENANCE OF SPILLWAYS AND CONTROL STRUCTURES
A. Inspection of the Skimmer Device
After every significant rainfall event (1" rainfall) or monthly, check and clear the skimmer device of
any obstructions such that draw down of the temporary runoff pool occurs within 2 to 5 days as
designed. At the downstream end of the outlet conduit pipe, the underside should be inspected for
seepage or piping at the interface with the soil. The spillway conduit should also be inspected for
blockages and sagging. The skimmer device is equipped with a screen to prevent trash from
entering the outlet conduit pipe. Maintenance should include periodically checking the skimmer for
broken sections and repairing as needed. The trash screen should be checked frequently,
especially after storm events to ensure that it is properly functioning and to remove accumulated
debris or trash.
B. Inspection of the Riser-Barrel Structure
The structure and the conduit should be visually inspected for deteriorating joints, cracking,
spalling, displacement of joints, and seepage. Problems with concrete pipes most often occur at
joints and special attention should be given to them during inspection. Joints should be checked
for gaps caused by elongation or settlement. Open joints can permit erosion of the embankment
material and possibly the piping of soil material through the joints. A depression in the soil surface
adjacent to the spillway may be a sign that soil is removed from around the spillway. If problems
are detected around the spillway, retain the services of a qualified civil engineer or geotechnical
engineer in the design of embankments to perform an inspection of the dam.
A trash rack is installed at the top of the riser barrel to prevent debris blockage of the structure.
The trash rack and pond floor should be visually inspected and any debris found should be
immediately removed and properly disposed.
OPERATION
A. Pond drains
The riser is equipped with a 4-inch drain device so that the pond can be completely drained in
the event the skimmer device becomes clogged, needs maintenance or repair. Generally,
when draining the pond, it should be done slowly.
B. Record Keeping
? Annual Inspection Reports-Annual inspections of the stormwater facilities must be made and
a written inspection report must be provided to the City of Raleigh Inspections Department. A
qualified registered North Carolina professional engineer, surveyor, or landscape architect may
provide the report. Inspections shall be on forms supplied by the City. An original inspection
report shall be given to the Department of Inspections each April, beginning in 2004. A
collection of written inspection reports should be kept on record in Section Vlll of this manual.
? Observations -All observations should be recorded. Where periodic inspections are performed
following significant rainfall events (1-inch storm event or greater), these inspections should be
logged into the Periodic Inspection, Operation & Maintenance Form in Section Vlll of this
manual.
? Maintenance - Written records of maintenance and/or repairs should be recorded on the
Periodic Inspection, Operation and Maintenance Form in Section VIII of this manual.
? Other Operational Procedures -The owner should maintain a complete and up-to-date set of
plans (as-built drawings). All changes made to the stormwater management facilities overtime
should be recorded on the as-built drawings.
B. Sedimentation
Runoff entering the pond will eventually result in sediment accumulation in the pond area.
Sediment will have to be removed once it adversely affects the function of the storm water facility.
The pond area will require sediment removal when six inches of deposition is present above the
design bottom elevation. In most cases, clean out of these areas of sediment will likely occur
every 5 years. The frequency of sediment removal may be reduced by ensuring site areas around
the pond are stabilized with vegetation. This would include a periodic application of fertilizer and
other treatments necessary to promote a stable ground cover and minimize sedimentation to the
ponds.
Due to the pond's small size, the dry detention pond can be mucked out with a portable mudcat
or backhoe. The removed material should be hauled offsite to a suitable landfill site or
mounded somewhere on site and stabilized with a ground cover sufficient to restrain erosion.
