The Knolls at Turkey Creek Section H
Low Density Subdivision Project
Pender County
Dear Mr. Gerow:
The Wilmington Regional Office received a complete Stormwater Management Permit Application for
The Knolls at Turkey Creek Section II on March 16,2016. Staff review of the plans and specifications
has determined that the project,as proposed,will comply with the Stormwater Regulations set forth in
Session Law 2008-211 and Title 15A NCAC 2H.1000.We are forwarding Permit No. SW8 151209,
dated March 17,2016,for the construction of the built-upon area associated with the subject project.
Please read Section I(7)carefully. As shown on the approved plans,this project proposes several piped
collection systems on steep slopes. Each system uses two weirs to dissipate energy and reduce the flow
velocity. This is permitted as an"alternative method where natural topography or other physical
constraints prevents the use of vegetated swales(subject to a case.by case review),"per 15A NCAC 2H
.1002(18) and as an"alternative design"per 15A NCAC 2H .1008(h). If the system does not function
appropriately,the permittee will be required to remove these systems and replace them with alternative
treatment.
This permit shall be effective from the date of issuance until rescinded and shall be subject to the
conditions and limitations as specified therein,and does not supersede any other agency permit that may
be required. Please pay special attention to the conditions listed in this permit regarding the Operation
and Maintenance of the BMP(s),recordation of deed restrictions,certification of the project,procedures
for changing ownership,and transferring the permit. Failure to establish an adequate system for operation
and maintenance of the stormwater management system,to record deed restrictions,to certify the project
or to transfer the permit in a timely manner,will result in future compliance problems.
If any parts,requirements,or limitations contained in this permit are unacceptable,you have the right to
request an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings
(OAH). The written petition must conform to Chapter 150B of the North Carolina General Statutes.Per
NCGS 143-215(e)the petition must be filed with the OAH within thirty(30)days of receipt of this
permit. You should contact the OAH with all questions regarding the filing fee(if a filing fee is required)
and/or the details of the filing process at 6714 Mail Service Center,Raleigh,NC 27699-6714,or via
telephone at 919431-3000,or visit their website at www.NCOAH.com.Unless such demands are made
this permit shall be final and binding.

FOR THE
construction, operation and maintenance of a 24% low density subdivision project in compliance with
the provisions of Session Law 2008-211 and Title 15A NCAC 2H .1000 (hereafter referred to as the
"stormwater rules') and the approved stormwater management plans and specifications, and other
supporting data as attached and on file with and approved by the Division of Energy, Mineral and
Land Resources (hereafter referred to as the Division or DEMLR) and considered a part of this permit.
The Permit shall be effective from the date of issuance until rescinded and shall be subject to the
following specific conditions and limitations:
I. DESIGN STANDARDS
1. The overall tract built-upon area percentage for the project must be maintained at 24% per the
requirements of the stormwater rules. This permit covers the construction of a total of 805,783
square feet of built-upon area (BUA), which includes 716,005 square feet of proposed BUA
and 89,778 square feet of future BUA.
2. Each of the 124 lots is limited to a maximum of 4,500 square feet of built-upon area, as
indicated on the application and/or as shown on the approved plans.
3. The only runoff conveyance systems allowed will be vegetated conveyances such as swales
with minimum side slopes of 3:1 (H:V) as defined in the stormwater rules and approved by the
Division.
4. No piping shall be allowed except those minimum amounts necessary to direct runoff beneath
an impervious surface such as a road or under driveways to provide access.
5. The project shall provide and maintain a minimum 50-foot wide vegetative buffer adjacent all
surface waters, measured horizontally from and perpendicular to the normal pool of
impounded structures, the top of bank of each side of streams and rivers and the mean high
water line of tidal waters. All runoff directed into and through the vegetative buffer must flow
through the buffer in a diffuse manner. Roof drainG n;ust terminate at the outer edge of the
buffer.
6. Stormwater runoff that is directed to flow through any wetlands shall flow into and through
these wetlands at a non-erosive velocity.

7. As shown on the approved plans, this project proposes several piped collection systems on
steep slopes. Each system uses two weirs to dissipate energy and reduce the flow velocity.
This is permitted as an "alternative method where natural topography or other physical
constraints prevents the use of vegetated swales (subject to a case by case review)," per 15A
NCAC 2H .1002(18) and as an "alternative design" per 15A NCAC 2H .1008(h). If the system
does not function appropriately, the permittee will be required to remove these systems and
replace them with alternative treatment.

establish an Architectural Review Board (ARB) or Committee (ARC) to review new and
modified lot development plans for compliance with the Covenants and Restrictions, including
the BUA limit. However, any approval given by the ARB or ARC on behalf of the permittee
does not relieve the permittee of the responsibility to maintain compliance with the overall
permitted built-upon area for the project.
4. The permittee is responsible for verifying that the proposed built-upon area on each individual
lot, and for the entire project, does not exceed the maximum allowed by this permit. The
permittee shall routinely monitor the lots and where a lot is determined to have exceeded the
permitted maximum BUA, the permittee shall notify the lot owner of such in writing and shall
require remediation within a reasonable time frame to bring the lot into compliance.
5. Swales, vegetated areas and other vegetated conveyances shall be constructed in their
entirety, vegetated, and operational for their intended use prior to the construction of any built-
upon surface, per the approved plans.

Low Density Residential Subdivisions
Deed Restrictions & Protective Covenances
In accordance with Title 15 NCAC 2H.1000 and S.L. 2006-246, the Stormwater Management
Regulations, deed restrictions and protective covenants are required for Low Density Residential
Subdivisions where lots will be subdivided and sold. Deed restrictions and protective covenants are
necessary to ensure that the development maintains a "built-upon" area consistent with the applicable
regulation governing the density level.
I, Scott Gerow acknowledge and affirm by my signature below, that I will cause the following deed
restrictions and protective covenants to be recorded for The Knolls at Turkey Creek Section 2 prior to
the sale of any lot:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number a , as issued by the Division of Water Quality under
the Stormwater Management Regulations.
2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to
maintain compliance with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties claiming
under them.
4. The covenants pertaining to stormwater may not be altered or rescinded without the express
written consent of the State of North Carolina, Division of Water Quality.
5. Alteration of the drainage as shown on the approved plan may not take place without the
concurrence of the Division of Water Quality.
6. The maximum allowable built-upon area per lot is 4,500 square feet. This allotted amount
includes any built-upon area constructed within the lot property boundaries, and that portion of the
right-of-way between the front lot line and the edge of the pavement. Built upon area includes, but
is not limited to, structures, asphalt, concrete, aravel. brick, stone. slate, and coauina, but does
not include raised, open wood decking, or the water surface of swimming pools.
7. In the case of a lot within CAMA's regulated AEC, where the Division of Coastal Management
calculates a different maximum allowable built-upon area for that lot than is shown herein, the
governing maximum built-upon area for that lot shall be the most restrictive of the two.
8. Filling in or piping of any vegetative conveyances (ditches, swales, etc.) associated with the
development except for average driveway crossings is strictly prohibited by any persons.
9. Each lot will maintain a 30*foot wide vegetated buffer between all impervious areas and surfac
waters. '
In All roof drains shall terminate at least 30*foot from the mean high water mbi�c of surface waters
DEC a 7 2016
*50 foot for projec cated in the 20 coastal counties. '

Subject: RE: SW8 151209, The Knolls at Turkey Creek
I'm bringing you revised plans and an updated application. I've tried to comb throu-h everything and make sure there
are no discrepancies where information is reported in multiple places.
Revisions include:
I recalculated the project area using the new boundary(same boundary that I submitted on the last plan with bearings
and distance) and found the area to be 77.08 acres. I've reported this on the plans, application,and low density
supplement. The allowable BUA has been recalculated and reported on these documents as well.
r
The BUA changes due to the road realignment and the elimination of 1 let have been incorporated into the plans,
application, and low density supplement.
The errant elevation in swale 3 behind lot 135 has been corrected.
I've eliminated the pipe and weir schedules and placed the information for each pipe, weir and swale on the plan. This
includes the roadway culverts and outfall pipes.
I intended to submit the Creekfront Recreation Area site plan along with the 3/8 submittal. We will be submitting for a
CAMA major permit and have noted this on the site plan. Holley clarified that the proposed elevated walkway within
the AEC is going to trigger it regardless of what we do with the parking lot and boat ramp. I hope this does not
convolute your review to the point that it must be returned.

Luke,
Please see attached. I talked Georgette into letting me send a 3rd add info rather than returning this project. But, FYI, if
we aren't able to get it out on this round it will have to be returned. I think it is pretty close though.

Luke,
Here is what I found out followine our phone call today
1.) 4"#57 Gravel on fabric=pervious in the buffer: I talked to Georgette, and we can't think of any reason why you
couldn't put the"pervious"gravel in the buffer. I have attached the guidance that Raleigh put together on
this. As long as you meet the rule requirements we will permit it.
2.) Impervious&CAMA: I talked to Holley Snider. She said that any type of gravel road regardless of the 4" 57
Stone issue is impervious. If you have impervious inside 30ft of MHW then please give her a call so she can tell
you the necessary details.
Thanks,

The Knolls at Turkey Creek,Section H
Pender County
Dear Mr. Gerow:
The Wilmington Regional Office received a Stormwater Management Permit Application for The Knolls
at Turkey Creek Section H on December 7,2015. A request for information was mailed on February 8,
2015,and a response was received on February 23,2016. A second request for information was mailed
on February 26,2016 and a response was received on March 8,2016. A preliminary review of that
information has determined that the application is not complete. The following information is needed to
continue the stormwater review:
1.) Reconfiguration: The project was reconfigured between February 23,2016 and March 8,2016.
Two cul-de-sacs in the middle of the project have been removed and swales have been re-routed
in the middle of the project.
a. Application: Please update the application to reflect the impervious area changes.
b. Number of Lots: The low density supplement shows 125 lots,but there appear to be 124
lots [43-165 (123 lots)and also a lot 28 on the eastern tip of the project for a total of 124
lots].
c. Swale Near Lot 135: This Swale is not numbered(it may be an extension of Swale#3`l).
Please check the elevations. There appears to be a low spot behind Lot 135.
2.) Pipes and Swales:
a. Labels: Please label all pipes and swales.
b. Elevations:
i. Weir Elevations: Please show the elevation of each weir on the plans.
ii. Pipes: The pipe schedule does not show all pipes. For instance,the pipes at the
outfalls of swales 5 and 6 do not appear on the pipe schedule. Please show all
pipe inverts.
3.) Sheet 16: On February 22,2016 your engineer and I discussed Clutch Drive with Holley Snider
of DCM/CAMA. It was my understanding that you had planned on staying out of the CAMA
buffer in order to avoid CAMA permitting. But, Sheet 16 was not re-submitted on March 81 to
show the proximity of Clutch Drive to the stream. Please make the appropriate changes to Sheet
16.
Please keep in mind that changing one number may change other numbers and require the calculations,
supplements,and other supporting documentation to be updated. Verify all numbers are correct to ensure
consistency in the application documents.

Re: The Knolls at Turkey Creek Section 2

Dear Kelly,
Please find the attached plans and calculations along with the following comments in response to your comments
dated 2/26/2016.
1. There is no objection to noting in the permit text that the pipe system must function as intended or be
replaced. I am content the outfall pipes will work better than an open ditch.
2. The detail sheet now includes schedules for pipe and weir elevations as well as weir lengths.
3. The common areas are now labeled as variable width public drainage easements.
4. I've resized the emergency weirs(those weir which serve as a backup for the piped outfalls)to provide a 10
year storm flow velocity of 2 fps in the event the pipes are clogged. This length is conservative,as these
weirs do no discharge directly to wetlands. The lengths are listed in a weir schedule on the detail sheet.
5. The velocities reported in the pipe calculations are only applicable inside the pipe. These are very high, as
it is a steep section of pipe. This energy is dissipated by the box at the bottom of the hill. The water flows
up and out of the box and then over the outfall weir. This weir is sized to create a wide,shallow flow path
prior to runoff reaching the wetlands. The weir calculations report the velocities of the water as it crosses
the x�,cir prior to reaching the wetlands. These velocities are less than? 41s.
Thank you again for your assistance with this project. Please let me know if you have any further questions or
concerns.
Respectfully,
a

The Knolls at Turkey Creek,Section H
Pender County
Dear Mr.Gerow:
The Wilmington Regional Office received a Stormwater Management Permit Application for The Knolls
at Turkey Creek Section II on December 7,2015. A request for information was mailed on February 8,
2015,and a response was received on February 23,2016. A preliminary review of that information has
determined that the application is not complete. The following information is needed to continue the
stormwater review:
Pipes: We have discussed the pipes in the previous two letters. As you have noted,low density
projects prohibit collections systems. But, collection systems per NCA C 2H.1002(18),do nct
include"...alternative methods where natural topography or other physical constraints prevents
the use of vegetated swales(subject to a case-by-case review)". I have discussed this with staff
and we are aware of two low density projects which have used this interpretation of the rule to put
pipes on steep slopes. On one constructed project with a similar(but slightly different)approach,
the system blew out and ended up overflowing from the top. The other one is pending(with a
third slightly different design)as an in-field fix to unexpected topography,and hasn't been
finalized yet. If you are going to proceed with using pipes on the slopes in a low density project
we will need the following:
1. Permit Text: We will reference the collection systems rule in the permit text, note
the case-by-case approval,and include a note that if the project does not function as
intended that it will have to be removed and replaced with an alternate design.
2. Pipe Invert and Weir Elevations: Please put all of this data on the plans.
3. Easements: Please provide easements for all of the pipe systems.
4. Weir Sizes: You show a 15ft emergency overflow weir at the entrance of each pipe,
and a weir of varying sizes at the end of each pipe.
a. How were these lengths determined?
b. Are the weirs level and perpendicular to the Swale outlet, or will they be
curved to keep water from flowing around them? Please clad;this on the
plans.
5. Velocities: Please clarify the calculations. Are the velocities shown in the
calculations submitted the resultant velocities of the water leaving these devices(I
believe they are)?

Project Narrative—The Knolls at Turkey Creek, Phase 2 FEB 2 3 2016
Project Summary BY:
The purpose of this project is to construct residential homes on approximately 10.86 acres of land
located just south of Rocky Point, NC off NC133 at Carver Road. Sixteen (16) lots are planned in
phase two of this development. This parcel is on record and is most recently conveyed by Deed
Book 4458, Page 183 of the Pender County Registry. The parcel number is 3223-46-7092-0000.
The site is afforded public water. Sewer will be served by on-site drainfields.
Site Description
The topography of the site varies, with slopes of 0% to 5% on upland sections and slopes to 10%
around wetlands. The site is presently wooded. On the southern boundary there is a small pond.
The northerly boundary includes a large wetland area along the run of Turkey Creek. Most of the
site drains into Turkey Creek except for a small amount that drains into the existing pond. Turkey
Creek is immediately tributary to the Northeast Cape Fear River.
Adjoining Property
Adjoining property is residential. The property to the east is subdivided into single family
residential lots. The property to the west is undeveloped and wooded. Across Carver road to
the south is another single family subdivision. The flood plain of Turkey Creek is to the north.
Soils
Soils in the project area are mapped in the Pender County Soil Survey as predominantly
Autryville Fine Sand with Marvyn on the slope into the floodplain and Dorovan throughout the
wetland fioodpiain area. Autryville I-ine Sand is characterized as a well drained soil with rapid
infiltration and slow surface runoff. Marvyn is a loamy fine sand typically found along slopes.
Dorovan is characterized as poorly drained and lying in flood prone areas. There is also an
insignificant amount of Pt(Pit) soil on the western, boundary. It is known for areas that have been
excavated. Preliminary analysis by a soil scientist indicates that there is adequate space for
onsite septic systems on all of the lots.
Planned Erosion and Sedimentation Control Practices
Silt fencing will be utilized where ground disturbance is in close proximity to wetlands, around the
existing pond and around drainage inlets to control sedimentation. A construction entrance will
be located at the entrance of phase two on Tom's Creek Road. A number of sediment traps will
be located at the locations of proposed swales, adjacent to existing swales, and in the roadside
ditches during construction where channelized flow will be adjacent to construction traffic.
Planned Stormwater Management Practices
This project is to be low density. Stormwater from lots will flow to swales or overland to adjacent
wetlands. Stormwater from the roadway will be collected in road side swales and conveyed to
vegetated swales and outlet to Turkey Creek. These outlets will feature permanent slope drains,
which are provided to convey water down the steep sections of the outfalls. Along the creek
frontage, the elevation drops up to 15' in distances ranging from 50'to 100'. The resulting slopes
range from 15%to 30%. In order to keep these outfalls from becoming a perpetual maintenance
burden and a source of sedimentation, water is conveyed through a section of pipe to concrete
bubble up structures at the toe of the slope, which serve to dissipate the energy. The water is

Re: The Knolls at Turkey Creek Section 2
SW8 151209
Dear Kelly,
I've reviewed the attached comments from 2/8/2016 and have made revisions and/or provided additional
information where applicable. The updated plans, calculations, and supporting documents are attached. I
have attempted to respond to your comments as follows:
La.Bearings and distances of boundary lines are now reported on the plan. The boundary per the deed is
the creek bank,so this line is also used to establish the 50' buffer.
l.b. Section 2(SW8 151209)is adjacent to Section 1,Phase 2 (SW8 150211).
1.c. The lower portion of Clutch Drive(40' private R/W)coincides with an existing stone/dirt road that
terminates into the creek. The proposed pavement is going to end just beyond the R/W line and the area
that has historically been used as a canoe/small boat launching area will be stabilized with#57 stone. I
have added a sheet to the plans to better illustrate the proposed improvement and drainage patterns.
2. You are correct,this project should be permitted as The Knolls at Turkey Creek Section 2. It appears
that section 1.1. of SWU-101 is the only place that omitted the"section 2"designation. I'm providing an
updated page 1.
3. I've shown the top of bank of the creek(which coincides with the boundary line)and the 50' buffer
line.
4. Outfall velocities are ultimately controlled by the weirs at the bottom of the slope drains. I've
lengthened these weirs as necessary to limit the velocity to 2 fps. Please note that weirs have been added
to Clutch Drive per comment 6.b.

rl 5. The pipes are permanent slope drains, which are provided to convey water down the steep sections of
the outfalls. Along the creek frontage,the elevation drops up to 15' in distances ranging from 50' to 100'.
The resulting slopes range from 15%to 30%. In order to keep these outfalls from becoming a perpetual
maintenance burden and a source of sedimentation,water is conveyed through a section of pipe to concrete
bubble up structures at the toe of the slope,which serve to dissipate the energy. The water is discharged
over a weir to further limit its velocity and prevent scour. It should be noted that the water entering these
pipes is already treated by way of vegetated roadside and outfall swales and,while the piped sections do
not provide any additional treatment,they do prevent the runoff from picking up sediment. I'm content
that these outfalls qualify as"alternative methods where natural topography or other physical constraints
prevents the use of vegetated swales"that are allowed on a case by case basis in 5A NCAC 2H .1002(18).
Please let me know if I need to make a more formal request for such a review. I had intende o expan
on this in a narrative or cover letter, but it must have slipped my mind. Sorry for the confusion. I did
update the detail to make it a little easier to follow what is going on at these outfalls.
6.a. The roadway typical cross section has been revised to more clearly depict swales on both sides of the
road.
6.b. I've added the swales and respective outfall weirs along Clutch Drive. These swales,numbered as
#7 and#8,will discharge to sediment traps during construction. Upon site stabilization,these traps will be
cleaned out and reshaped into blind swales that discharge over a small weir section that will ensure the
flow is held below 2 FPS. Please note that these basin type features are not intended to satisfy any specific
BMP requirement.
6.c. Yes,the intent is for the common area—which is an old borrow pit—to fill up to a point and then
overflow through outfall#3. The soils are granular and readily infiltrate water,so the pond is not
anticipated to remain at the stage of the outfall swale. Having said that,there has been some recent
discussion regarding how high this area should be allowed to stage up before it can outfall. The result is
that the swale elevation that controls the pond stage has been lowered to 17.2.
6.d. I trust you mean 86 and 110? Yes,there is a divide here. I did not show the swale extending across
the back of 86/110 because I did not feel it necessary to cut the full swale section into this area where more
selective, localized lot grading could accomplished the same thing. To avoid any confusion,I've shown
the diverging swales starting at the drainage break.
Thank you in advance for your attention to this matter. Please let me know if you have any further
questions regarding this project.
Respectfully,
David L. Menus,P.E.

Luke,
Here is what I found out following our phone call today:
1.) 4"#57 Gravel on fabric=pervious in the buffer: I talked to Georgette, and we can't think of any reason why you
couldn't put the "pervious"gravel in the buffer. I have attached the guidance that Raleigh put together on
this. As long as you meet the rule requirements we will permit it.
2.) Impervious&CAMA: I talked to Holley Snider. She said that any type of gravel road regardless of the 4" 57
Stone issue is impervious. If you have impervious inside 30ft of MHW then please give her a call so she can tell
you the necessary details.
Thanks,

Dear Mr. Gerow:
The Wilmington Regional Office received a Stormwater Management Permit Application for The Knolls
at Turkey Creek Section 11 on December 7,2015. A preliminary review of that information has
determined that the application is not complete. The following information is needed to continue the
Ili stormwater review:
1. Bearing and Distance Lines [per 15A NCAC 02H.1003(g)(5)and 02H.1005(d)]:
`'9. Lines: Please show bearingdistance lines for the
project area on the plans.
%4 Overiap: Please verify that this project will not overlap the other two Knolls at Turkey
Creek projects, SW8 130514 and SW8 150211.
vf Clutch Road: This road appears to dead-end at the wetland(stream?)line. Where will
this lane go? It does not go all the way to the project's edge and there is no cul-de-sac.
u! Project Name: For clarification to distinguish this project from the other two,we recommend that
you add"Section H"to the end of"The Knolls at Turkey Creek".

' 5. Pipes [per 15A NCAC 02H.1002(18)]: There appear to be a pipes at the ends of several swales,
which is prohibited in low density projects.
6. Swales:

Label all Swales: Please label and provide discharge calculations for all swales. (For
instance whom does the water draining from Clutch Road discharge,and what is the
water's velocity?)

or is there a typo in the elevation data?
Lots 86 and 100: Is there a Swale between these two lots? It looks like there is a
drainage divide,but that there is no Swale.
Please keep in mind that changing one number may change other numbers and require the calculations,
supplements, and other supporting documentation to be updated. Verify all numbers are correct to ensure
consistency in the application documents.
Please note that this request for additional information is in response to a preliminary review. The
requested information should be received in this Office prior to March 8,2016,or the application will be
returned as incomplete. The return of a project will necessitate resubmitta.l of all required items, including
the application fee.
If you need additional time to submit the information,please email or fax your request for a time
extension to the Division at the address and fax number at the bottom of this letter.Please note that a
second significant request for additional information may result in the return of the project. If the project
is returned,you will need to reschedule the project through the Express coordinator for the next available
review date, and resubmit all of the required items, including the application fee.
The construction of any impervious surfaces, other than a construction entrance under an approved
Sedimentation Erosion Control Plan,is a violation of NCGS 143-215.1 and is subject to enforcement
action pursuant to NCGS 143-215.6A.

1 Precipitation frequency(PF)estimates in this table are based on frequency analysis of partial duration series(PDS).
Numbers in parenthesis are PF estimates at lower and upper bounds of the 90%confidence interval.The probability that precipitation frequency
estimates(for a given duration and average recurrence interval)will be greater than the upper bound(or less than the lower bound)is 5%.Estimates
at upper bounds are not checked against probable maximum precipitation(PMP)estimates and may be higher than currently valid PMP values.

Project Narrative
The Knolls at Turkey Creek Section 2
Project Summary
The purpos/ofhis project is to construct residential homes on approximately 72.8 acres
of land located just south of Rocky Point, NC off NC133 at Carver Road. One hundred and
twenty seven (427),lots are planned in the remaining phases of this development. Phases one
and two have beeg'previously approved and are mostly built out. The two parcels on which this
project is proposed were recently acquired and are on record at Deed Book 4461, Page 294 of
the Pender County Registry. The parcel numbers are 3223-35-4303-0000 and 3223-35-4303-
0000. The site is afforded public water. Sewer will be served by on-site drainfields. The existing
ponds and immediately adjacent shores will be dedicated to common area. There is an existing
boat ramp that is planned to be improved and also dedicated as common area.
Site Description
The topography of the site varies, with slopes of 0%to 5%on upland sections and slopes
to 10% around wetlands. The site is presently wooded. The Knolls at Turkey Creek Phase Two `
is on the eastern boundary which includes a small pond. There is also a small pond in the
property's interior. The northern boundary includes a large wetland area along the run of Turkey
Creek. Bellhammond subdivision forms the southern boundary. Most of the site drains into
Turkey Creek except for a small amount that drains into the existing ponds. Turkey Creek is
immediately tributary to the Northeast Cape Fear River.
Adjoining Propertv
Adjoining property is residential. Properties to the east and south are subdivided into
single family residential lots. Across Carver road to the southeast is another single family
subdivision. The flood plain of Turkey Creek is to the north.
Soils
Soils in the project area are mapped in the Pender County Soil Survey as predominantly
Autryville Fine Sand with Marvyn on the slope into the floodplain and Dorovan throughout the
wetland floodplain area. Autryville Fine Sand is characterized as a well drained soil with rapid
infiltration and slow surface runoff. Marvyn is a loamy fine sand typically found along slopes.
Dorovan is characterized as poorly drained and lying in flood prone areas. There are also a a
couple Pt(Pit) soils within the boundary. These are known for areas that have been excavated.
Preliminary analysis by a soil scientist indicates that there is adequate space for onsite septic
systems on all of the lots.
Planned Erosion and Sedimentation Control Practices
Erosion control for this section of the project will be accomplished in 2 phases. The initial
construction phase will be limited to work in rights of way and drainage easements and will
include the installation of pipes, roadside.ditches and swales. Sediment basins, sediment traps,
and construction entrances will be utilized to keep sediment onsite during this phase. These
measures will remain in place until the 16 acres of disturbed areas have been stabilized through
vegetation or pavement. The second phase will consist of home construction. Sediment will be
kept on individual lots by way of silt fencing.
Planned Stormwater Management Practices
This project is to be low density. Stormwater from lots will flow to swales or overland to
adjacent wetlands. Stormwater from the roadway will be collected in road side swales and
conveyed to vegetated swales and outlet to Turkey Creek.
