amended, and other applicable Laws, Rules, and Regulations promulgated and adopted by the North
Carolina Environmental Management Commission, including 15A NCAC 02H.1000 amended on
January 1, 2017 (2017 Rules) (the "stormwater rules"),
PERMISSION IS HEREBY GRANTED TO
EYC Companies, LLC and Alvin Bryan Willis, Ill
Heartsease at Calabash
Persimmon Road, Calabash, Brunswick County
FOR THE
construction, management, operation and maintenance of built-upon area (BUA) draining to two (2)
wet detention ponds ("stormwater control measures" or"SCMs") as outlined in the application,
approved stormwater management plans, supplement, calculations, operation and maintenance
agreement, recorded documents, specifications, and other supporting data (the "approved plans and
specifications") as attached and/or on file with and approved by the Division of Energy, Mineral and
Land Resources (the "Division" or"DEMLR"). The project shall be constructed, operated and
maintained in accordance with these approved plans and specifications. The approved plans and
specifications are incorporated by reference and are enforceable part of this permit.
This permit shall be effective from the date of issuance until August 18, 2030 and shall be subject to
the following specified conditions and limitations. The permit issued shall continue in force and effect
until the permittee files a request with the Division for a permit modification, transfer, renewal, or
rescission; however, these actions do not stay any condition. The issuance of this permit does not
prohibit the Director from reopening and modifying the permit, revoking and reissuing the permit, or
terminating the permit for cause as allowed by the laws, rules, and regulations contained in Title 15A
NCAC 2H.1000 and NCGS 143-215.1 et.al.
1. BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 739,463
square feet. The runoff from all BUA within the permitted high density drainage areas of this
project must be directed into the permitted SCMs. The BUA requirements and allocations for
this project are as follows:
a. SCM BUA LIMITS. The SCMs labeled DA1 and DA2 have been designed to handle the
runoff from 585,165 and 146,939 square feet of BUA, respectively, within the delineated
drainage areas. The BUA for future development within the drainage areas to the SCMs
labeled DA1 and DA2 is limited to 154,969 and 42,624 square feet, respectively. This permit
approves 7,359 square feet of BUA that was not able to be collected and treated in an SCM
due to grading constraints to bypass the system.
b. CAMA AECs. Where a project or lot is located within CAMA's Area of Environmental
Concern (AEC), the Division of Coastal Management (DCM) may calculate a different
maximum BUA based on CAMA regulations. The more restrictive BUA limit will apply to the
project.

2. PERVIOUS AREA IMPROVEMENTS. At this time, none of the pervious area improvements
listed in G.S. 143-214.7(b2) or the Stormwater Design Manual have been proposed for this
project. Pervious area improvements will be allowed in this project if documentation is provided
demonstrating those improvements meet the requirements of the stormwater rule.
3. SCM REQUIREMENTS. The SCM requirements for this project are as follows:
a. SCM DESIGN. The SCMs are permitted based on the design criteria presented in the
sealed, signed and dated supplement and as shown in the approved plans and
specifications. These SCMs must be provided and maintained at the design condition.
b. PLANTING PLAN. The SCM landscape planting plan shown in the approved plans shall be
followed in its entirety during construction. After the plants are established, the operation
and maintenance agreement must be followed.
c. FOUNTAINS. At this time, a decorative spray fountain has not been proposed within the wet
pond. Decorative spray fountains will be allowed in the wet pond if documentation is
provided demonstrating that the proposed fountain will not cause resuspension of sediment
within the pond or cause erosion of the pond side slopes.
d. IRRIGATION. If the wet pond is to be used for irrigation, it is recommended that some water
be maintained in the permanent pool, the vegetated shelf is planted with appropriate species
that can handle fluctuating conditions, and human health issues are addressed.
4. NON-ENFORCEABLE SCMS. The pond labeled SCM #1 B shown on the plans is not required
by the Division and has not been demonstrated to meet the Minimum Design Criteria and
therefore is not considered a part of the approved stormwater treatment system. This additional
measure is incorporated only by reference and is not enforceable parts of the permit.
5. STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not cause
erosion downslope of the discharge point.
6. VEGETATED SETBACKS. A 50-foot wide vegetative setback must be provided and maintained
in grass or other vegetation adjacent to all surface waters as shown on the approved plans. The
setback is measured horizontally from the normal pool elevation of impounded structures, from
the top of bank of each side of streams or rivers, and from the mean high waterline of tidal
waters, perpendicular to the shoreline.
a. BUA IN THE VEGETATED SETBACK. BUA may not be added to the vegetated setback
except as shown on the approved plans.
b. RELEASE OF STORMWATER NOT TREATED IN AN SCM. Stormwater that is not treated
in an SCM must be released at the edge of the vegetated setback and allowed to flow
through the setback as dispersed flow.
7. RECORDED DOCUMENT REQUIREMENTS. The stormwater rules require the following
documents to be recorded with the Office of the Register of Deeds:
a. EASEMENTS. All SCMs, stormwater collection systems, vegetated conveyances, and
maintenance access located on property owned by other persons or entities must be located
in permanent recorded easements or drainage easements as shown on the approved plans.
b. OPERATION AND MAINTENANCE AGREEMENT. The operation and maintenance
agreement must be recorded with the Office of the Register of Deeds.
c. FINAL PLATS. If a final plat is recorded, it must reference the operation and maintenance
agreement and must also show all public rights-of-way, dedicated common areas, and/or
permanent drainage easements, in accordance with the approved plans.

Wet Pond Maintenance Requirements
Important operation and maintenance procedures:
Immediately after the wet detention basin is established, the plants on the vegetated shelf and
- perimeter of the basin should be watered twice weekly if needed, until the plants become
established (commonly six weeks).
No portion of the wet pond should be fertilized after the initial fertilization that is required to
- establish the plants on the vegetated shelf.
Stable groundcover will be maintained in the drainage area to reduce the sediment load to the wet
pond.
If the pond must be drained for an emergency or to perform maintenance, the flushing of sediment
- through the emergency drain will be minimized as much as possible.
At least once annually, a dam safety expert will inspect the embankment. Any problems that are
found will be repaired immediately.
The measuring device used to determine the sediment elevation shall be such that it will give an
accurate depth reading and not readily penetrate into accumulated sediments.
After the wet pond is established, it will be inspected quarterly and within 24 hours after every storm event
greater than 1.0 inches (or 1.5 inches if in a Coastal County) . Records of operation and maintenance shall be
kept in a known set location and shall be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.

All, Al6O 1(/146
I have just had a chance to review.Thank you for the package,everything looks good!The only item I noticed was that
Row 44 of the wet pond supplement for SCM 1 seems to have been updated to show 78 inches,the same as Row 43.
Please update Rows 43 and 44 for SCM 1 in a way to support that the entrance to the forebay is deeper than the exit.
1

L �
While this page is being updated, if Row 6 for SCM 2 could also be updated from "yes"to "no"to reflect that there are
not any retaining walls as part of the SCM,this will be helpful for clarity.
A PDF copy of the entire supplement can be emailed to me and I will print it for the file. Once I have this updated
supplement, I will be able to issue the permit. I have begun to draft this permit.
Thanks!

State Stormwater Management Permit
NCDEQ Project No.SW8 220711
WR Project No.03210780.10
Dear Ms. Edmonds,
We are writing this letter in response to comments dated August 8, 2022. Each of the comments are
repeated below,followed by our response.
1. 15A NCAC 02H.1053(5)(a):
a. It was noted in the response letter that forebay 1 receives 90%of the drainage area to SCM
1A, however, the drainage areas to each forebay were not provided. Please provide the
drainage areas in square feet to each individual forebay.
b. Based on the information that forebay 1 receives 90%of the drainage area,it appears that
forebay 1 is undersized. Please provide forebay calculations supporting that forebay#1 will
remain between 15 to 20 percent of the provided main pool volume based on the weighted
average of its proposed respective contributing drainage areas.
c. It was noted in the response letter that forebays 2 and 3 will be oversized due to
construction constraints. Please provide forebay calculations for forebays 2 and 3
supporting the forebay volume percentage of the provided main pool volume based on the
weighted average of their proposed respective contributing drainage areas. Please update
the narrative to provide this justification and documentation of the oversized forebays.
A)The 24"x36"drainage area map has been revised.The callouts for the forebay relative sizes
now include total drainage area to each.
' B)Forebay 1 has been increased in size to account for 15-20%of the main pool volume.
C)Additional calculations have been provided for SCM 1 forebay sizing.The narrative has been
revised to indude a summary of why Forebay 2 and 3 their allotted weighted volume.
2. 15A NCAC 02H.1042(2)(a)(iv), .1001(1)(c), and .1002(8): It appears that there is proposed BUA
within the right-of-way that is not currently included in a drainage area. Any right-of-way
improvements proposed for the development of this site are considered part of the common plan
of development must be included and accounted for in this project. Options for including these
improvements in the application package are:
a. Collect and treat the proposed built-upon area or an equal amount of existing built-upon
area;
b. Demonstrate these improvements meet the requirements of a low density project per
.1003(1)and.1003(2);or

rWithersRavenel
Our pBOLMu vnU,,u:
c. If these other options cannot be met and the improvements are minimized, meet the DOT
toolbox options,and bypasses the provided collection system,then the right-of-way built-
upon area can be quantified in a separate drainage area in Section IV.10 of the application.
Please also update the narrative to document and justify these improvements.
The widened turn lanes in the Right of Way(ROW)at the southern entrance proposes 7,359 SF
of impervious area. This is part of the NCDOT improvements required for the project and is
located in the NCDOT Right of Way. The disturbance for the road widening is less than one
acre and less than 10,000 sf of BUA.Therefore,if this was done as a separate project at a later
date it would not trigger a state stormwater permit or erosion control permit. We understand
that this is part of our overall project but is minimal in impact and otherwise would not require
permitting.
The pavement is not designed nor allowed by NCDOT with curb and gutter and cannot be
routed to an SCM onsite. Also,as stated this area is not within the project boundary,so we are
not considering a low-density portion of the project.
The runoff from this additional pavement will be collected via dispersed flow in the existing
roadside vegetated ditch. We have modeled the existing ditch along the property frontage to
show the impact of the additional impervious area to the ditch and it results in a 0.07 fps
velocity increase and a 0.05 feet elevation increase during the 10-year storm event. Velocity
remains below 2 fps in the ditch even with the slight increase in impervious area. See attached
calculations.
An additional drainage area was added to the application and supplement form with the total
area being the 7,359 SF of pavement in order to account for this area.Additional information
has also been added to the conclusion section of the narrative.
3. 15A NCAC 02H.1053(2): In the calculations in the second option for the average depth equation
for SCM 1, the volume of the main permanent pool is listed as 294,430 cubic feet, however, it is
listed as 332,871 cubic feet in the stage storage table. Please ensure this information is presented
consistently,including Rows 28-31 of the supplement.
► This has been revised with the regrading of Forebay 1.
4. 15A NCAC 02H.1053(11)(a): Row 53 of the wet pond supplement was updated from listing
centipede to TBD. The dam structure, including front and back embankment slopes, of the pond
shall be vegetated with non-clumping turf grass. Please reconsider the response in Row 53.
Bermuda has been selected to be planted on the dam.The supplement form has been revised.
5. 15A NCAC 02H.1042(3)(b): The chart above the wet pond grading detail on plan Sheet C9.06 is
inconsistent with other application documents.Please provide two copies of an updated plan sheet.
The supplement form and O&M have been revised to match the table on C9.06.
6. Due to the potentially minor nature of these comments,the express additional information review
fee has been waived.
t Thank you.
With this submittal,please find the attached updated Sheets C4.00,C5.00,C6.03,C9.00,C9.06,and L2.00.
Also included are an updated 24x36 signed drainage area map,Persimmon Road ditch calculations,updated
stormwater management plan narrative and SCM calculations,updated signed supplement EZ,revised wet
pond elevations page for O&M,and updated page 3 of the application.

Stormwater Management Report mu. r_
Town of Calabash, North Carolina
INTRODUCTION
The proposed Heartsease at Calabash residentiai community is located on a 40.43-acre parcel located off
Persimmon Road SW adjacent to the Saltaire Village residential community located in the Town of Calabash,
NC. The development will be comprised of single-family homes, multi-family homes, detached garages,
roadways,sidewalks,a community building,amenity areas,and other associated infrastructure including the
stormwater control measures(SCMs)discussed herein.The purpose of this study is to demonstrate that the
proposed site is following the requirements for coastal counties required by the Department of
Environmental Quality(DEQ)section 15A NCAC 02H.1019,the Brunswick County Stormwater Ordinance
and the Brunswick County Stormwater Management Manual.
The site in its existing conditions is mostly wooded.The site is bordered on all sides by ditches that convey
site drainage north to Persimmon Swamp, or west to the NCDOT right-of-way which ultimately leads to
Persimmon Swamp. The site is comprised of 28% HSG 'B' soils, and 72% HSG 'C' soils. A soils map and
drainage area map are provided in the sidLK.gtuuu0 Intormatw n section of this report.

Parcel outlined in cyan
The impacts of the increased runoff from the addition of impervious area from the development will be
mitigated with three wet pond stormwater control measures. Design calculations for the proposed SCMs
are included in the ;ziag Cal^ is:'c is section of this report.
STORMWATER MANAGEMENT REQUIREMENTS
The proposed development drains to Persimmon Swamp in the Lumber River basin.The site is in a coastal
county and must therefore meet the requirements outlined by the Coastal State Stormwater Program which
requires the design storm depth for high density projects to be 1.5". The proposed primary SCMs are
designed per DEQ's Minimum Design Criteria and will reduce Total Suspended Solids(TSS)through dilution
and settlement. Pcr the Brunswick County Stormwater Management Manual, post-development peak flow
is to be attenuated to pre-development levels in the 1-year 24-hour storm,and peak flow may not increase
by more than 5%from pre-development peak flows for the 10-year 24-hour storm.A computation of the
average potential pollutant export from each new development in Brunswick County must be provided for
Nitrogen Phosphorus,Total Suspended Solids,and Fecal Coliform.

Heartsease at Calabash
Stormwater Management Report
Town of Calabash, North Carolina
METHODOLOGY
The stormwater study was conducted using the natural drainage features as depicted by LIDAR topography
and existing field surveys. Proposed drainage areas were based on field survey data and proposed
development within the drainage areas.
The scope of work included the following analyses:
Hyd rol,ogy
Simulation of the 1-year, 2-year, 10-year, 25-year, and 100-year rainfall events for the Brunswick
County, NC area
Formulation of the 1-year, 2-year, 10-year, 25-year, and 100-year flood hydrographs for the pre-
and post-development drainage areas
Hydraulic
Routing the 1-year,2-year, 10-year,25-year,and 100-year flood hydrographs for predevelopment
runoff from the site.
► Routing the 1-year, 2-year, 10-year, 25-year, and 100-year flood hydrographs for post-
development runoff through the stormwater control measures(SCMs).
Analyzing results at the analysis points
The results of the hydrology calculations are used in the hydraulic analyses. The hydraulic design requires
the development of stage-storage and stage-discharge functions for the SCMs. The rainfall/runoff
hydrographs,stage-storage,and stage-discharge functions have been compiled to create a computer routing
simulation model using Bentley Systems PondPack v8i software. This PondPack model was then used to
assess the peak water surface elevations in the SCMs for the design rainfall events.The routing results are
provided as in the PondPack Routing alcu;a,',., s section of this report.
Hydrology
The SCS Method,in conjunction with the required rainfall depths for the 1-year and 10-year storms the in
Brunswick County Stormwater Management Manual, and NOAA Atlas 14 rainfall data for the 2-, 25-, and
100-year storms for the Brunswick County area, was used to develop runoff hydrographs for the storm
events.This method requires three basic parameters: a curve number(CN),time of concentration (tc), and
drainage area.
Curve numbers were based on soil type and land use.Soil types were delineated from the Natural Resources
Conservation Service (NRCS) web soil survey in Brunswick County, NC. The curve numbers used in this
study are listed in the Pon'!Pazk Ruu}r-g Ca.cula'ions section of this report.
Time of concentration for pre- and post-development drainage areas were developed using the methods
described in the NRCS TR-55 methodology for urban hydrology in small watersheds. A minimum time of
concentration of 5 minutes was used for proposed piped drainage systems.
Hydraulics
Computer simulated reservoir routing of the 1-year,2-year, 10-year, 25-year,and 100-year design storms
utilized stage-storage and stage-discharge functions. Stage-storage functions were derived from the
proposed geometry of the SCMs. A non-linear regression relation for surface area versus elevation was
derived for each SCM.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 proposed outlet structures for the SCMs.

CONCLUSIONS
Ougity
Based upon the routing study, the proposed stormwater management plan has sufficient measures to
provide the necessary removal of TSS as required by the Coastal State Stormwater Program. The SCM's
were designed to comply with DEQ's MDC for wet ponds which require forebays as a means to all sediment
to settle,and the ponds have adequate flow paths to allow for TSS removal through dilution and settlement.
SCM 1B acts as upstream detention for SCM 1A.SCM 1A has been sized for both 1A and 1B drainage areas.
Runoff flowing to SCM 1B is routed to SCM 1A in a controlled manner so as not to overwhelm it.
As part of the project NCDOT required additional turn lanes at the southern entrance of the project that
resulted in an additional 7,359 SF of BUA in the ROW.This pavement has no curb and gutter,and therefore
cannot be routed to an onsite SCM. The runoff associated with it sheet flows as dispersed flow across
adjacent vegetation before entering a vegetated road side ditch.
Quantity
The peak flows from the site have been attenuated for pre-development levels. Furthermore,the proposed
SCMs has sufficient storage to safely pass the 100-year storm event without overtopping of the primary
riser structures.

SCM #1A Forebays
SCM#1A has multiple inlets that have been separated into three(3)forebays.Drainage to Forebay 1 makes
up about 90% of the total drainage area to the SCM, therefore its volume was designed to be 15-20% of
the main pool volume per the MDC. Forebays 2 and 3 receive the remaining 10% of the drainage area to
the pond. If the total forebay volume were to remain between 15-20%of the main pool, Forebays 2 and 3
would not have matching depths to the main pool or Forebay 1.In addition,their surface areas would be so
minimal there are concerns about how quickly sediment would fill them,increasing their regular maintenance
cleanout.It is proposed that the total forebay volume exceed 20%so that Forebays 2 and 3 perform similarly
to Forebay 1 as a sediment trap prior to entering the main basin.Calculations for the forebay sizing can be
found in the SCM Sizing Calcul:`:'::ns section of this report.

SCM#2 - Design of Riprap Outlet Protection
Per NYDOT Dissioator Method for Use in Defined Channels
Step 1: Compute flow velocity at culvert outlet.
Velocity(Vo) = 3.5 ft/s (modeled broad crested weir in FlowMaster)
OR
Based on Q10= 12.48 CFS
Step 2: Determine Do
For circular pipe culverts, Do= Pipe Diameter
For pipe archs,archs,box culverts,and paved channel outlets, Do=4A0
Where Ao=cross-sectional area of flow at outlet
For multiple openings,Do= 1.25 x Do of single culvert
Culvert Type= Circular Pipe *To model Weir wall
Pipe Diameter(ft)= 2.50 *Area of the WQ weir up to weir crest
Single or Mulitple Openings= Single
Do= ft
Step 3: Determine zone for apron material per Figure 8.06C.
Note: For apron slopes>_ 10%,use next higher zone.

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions, along
with the maps,can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas.A map unit is identified and named
according to the taxonomic classification of the dominant soils.Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the
landscape, however, the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena. Thus,the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently, every map unit is made
up of the soils or miscellaneous areas for which it is named and some minor
components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management.These are called contrasting, or dissimilar, components.They
generally are in small areas and could not be mapped separately because of the
scale used. Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each.A few areas of minor
components may not have been observed, and consequently they are not
mentioned in the descriptions,especially where the pattern was so complex that it

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.
Please refer to NOAA Atlas 14 document for more information.

USACE JURISDICTIONAL DETERMINATION

U.S. ARMY CORPS OF ENGINEERS
WILMINGTON DISTRICT
Action Id. SAW-2021-01209 County: Brunswick County U.S.G.S.Quad:Calabash
NOTIFICATION OF JURISDICTIONAL DETERMINATION
Property Owner/Applicant: Joseph Floyd
The Brigman Company
Address: PO Box 1532
Conway.SC 29526
Telephone Number: [phone]
Email Address: iflovd(a),thebriamancompanv.com
Size(acres) 39.93 acres Nearest Town Calabash,NC
Nearest Waterway Shingletree Swamp River Basin Lower Pee Dee
USGS HUC 03040206 Coordinates Latitude: 33.90260
Longitude:-78.57230
Location description: This 39 acre project is located at 67 Persimmon Road in Calabash.Brunswick County,NC
(Parcel ID:24000016).
Indicate Which of the Following Apply:
A. Preliminary Determination
_ There are waters,including wetlands, on the above described project area, that may be subject to Section 404 of the Clean
Water Act(CWA)(33 USC§ 1344)and/or Section 10 of the Rivers and Harbors Act(RHA)(33 USC§403). The
waters,including wetlands, have been delineated,and the delineation has been verified by the Corps to be sufficiently accurate
and reliable. Therefore this preliminary jurisdiction determination may be used in the permit evaluation process,including
determining compensatory mitigation. For purposes of computation of impacts,compensatory mitigation requirements,and other
resource protection measures,a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that
would be affected in any way by the permitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary
determination is not an appealable action under thc Regulatory Program Administrative Appeal Process(Reference 33 CFR Part
331). However,you may request an approved JD,which is an appealable action,by contacting the Corps district for further
instruction.
_ There are wetlands on the above described property, that may be subject to Section 404 of the Clean Water Act(CWA)(33
USC§ 1344)and/or Section 10 of the Rivers and Harbors Act(RHA)(33 USC§403).However,since the
waters,including wetlands, have not been properly delineated,this preliminary jurisdiction determination may not be used in the
permit evaluation process. Without a verified wetland delineation,this preliminary determination is merely an effective
presumption of CWA/RHA jurisdiction over all of the waters,including wetlands, at the project area,which is not sufficiently
accurate and reliable to support an enforceable permit decision. We recommend that you have the waters of the U.S. on your
property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner,you may wish to
obtain a consultant to conduct a delineation that can be verified by the Corps.
B. Approved Determination
There are Navigable Waters of the United States within the above described property subject to the permit requirements of
Section 10 of the Rivers and Harbors Act(Ri-lA)(33 USC§403)and Section 404 of the Clean Water Act(CWA)(33 USC§
1344). Unless there is a change in law or our published regulations,this determination may be relied upon for a period not to
exceed five years from the date of this notification.

by the Corps Regulatory Official identified below on .Unless there is a change in the law or our published
regulations,this determination may be relied upon for a period not to exceed five years from the date of this notification.

permit requirements of Section 404 of the Clean Water Act(33 USC 1344). Unless there is a change in the law or our
published regulations,this determination may be relied upon for a period not to exceed five years from the date of this
notification.
X The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act
(CAMA). You should contact the Division of Coastal Management in Wilmington.NC to determine their requirements.
Placement of dredged or fill material within waters of the US,including wetlands,without a Department of the Army permit may
constitute a violation of Section 301 of the Clean Water Act(33 USC§ 1311). Placement of dredged or fill material,construction or
placement of structures,or work within navigable waters of the United States without a Department of the Army permit may
constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act(33 USC§401 and/or 403).If you have any questions
regarding this determination and/or the Corps regulatory program,please contact Gary Beecher at(910)251-4694 or

Good morning Kellie,
The "EW" is an abbreviation for excluded waters. The features onsite were determined to be excluded from federal
jurisdiction. I have confirmed with the USACE that these features are not streams but are in fact ditches dug entirely on
the high ground. I hope this helps and feel free to call or emaii if you have any other questions.

NOTIFICATION OF JURISDICTIONAL DETERMINATION
Property Owner/Applicant: Joseph Floyd
The Brigman Company

Size(acres) 39.93 acres Nearest Town Calabash.NC
Nearest Waterway Shingletree Swamp River Basin Lower Pee Dee
USGS HUC 03040206 Coordinates Latitude: 33.90260
Longitude:-78.57230
Location description: This 39 acre project is located at 67 Persimmon Road in Calabash,Brunswick County,NC
(Parcel ID:24000016).
Indicate Which of the Following Apply:
A. Preliminary Determination
There are waters,including wetlands, on the above described project area, that may be subject to Section 404 of the Clean
Water Act(CWA)(33 USC§ 1344)and/or Section 10 of the Rivers and Harbors Act(RHA)(33 USC§403). The
waters,including wetlands, have been delineated,and the delineation has been verified by the Corps to be sufficiently accurate
and reliable. Therefore this preliminary jurisdiction determination may be used in the permit evaluation process,including
determining compensatory mitigation. For purposes of computation of impacts,compensatory mitigation requirements,and other
resource protection measures,a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that
would be affected in any way by the permitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary
determination is not an appealable action under the Regulatory Program Administrative Appeal Process(Reference 33 CFR Part
331). However,you may request an approved JD,which is an appealable action,by contacting the Corps district for further
instruction.
There are wetlands on the above described property, that may be subject to Section 404 of the Clean Water Act(CWA)(33
USC§ 1344)and/or Section 10 of the Rivers and Harbors Act(RHA)(33 USC§403).However,since the
waters,including wetlands, have not been properly delineated,this preliminary jurisdiction determination may not be used in the
permit evaluation process. Without a verified wetland delineation,this preliminary determination is merely an effective
presumption of CWA/RHA jurisdiction over all of the waters,including wetlands, at the project area,which is not sufficiently
accurate and reliable to support an enforceable permit decision. We recommend that you have the waters of the U.S. on your
property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner,you may wish to
obtain a consultant to conduct a delineation that can be verified by the Corps.
B. Approved Determination
_ There are Navigable Waters of the United States within the above described property subject to the permit requirements of
Section 10 of the Rivers and Harbors Act(RHA)(33 USC§403)and Section 404 of the Clean Water Act(CWA)(33 USC§
1344). Unless there is a change in law or our published regulations,this determination may be relied upon for a period not to
exceed five years from the date of this notification.

_ There are waters of the U.S.,including wetlands, on the above described project area subject to the permit requirements of
Section 404 of the Clean Water Act(CWA)(33 USC§ 1344). Unless there is a change in the law or our published regulations,
this determination may be relied upon for a period not to exceed five years from the date of this notification.
_ We recommend you have the waters of the U.S. on your property delineated. As the Corps may not be able to accomplish
this wetland delineation in a timely manner,you may wish to obtain a consultant to conduct a delineation that can be verified by
the Corps.
_ The waters of the U.S.,including wetlands, on your project area have been delineated and the delineation has been verified
by the Corps. We strongly suggest you have this delineation surveyed. Upon completion,this survey should be reviewed and
verified by the Corps. Once verified,this survey will provide an accurate depiction of all areas subject to CWA jurisdiction on
your property which,provided there is no change in the law or our published regulations,may be relied upon for a period not to
exceed five years.
_ The waters of the U.S.,including wetlands, have been delineated and surveyed and are accurately depicted on the plat signed
by the Corps Regulatory Official identified below on .Unless there is a change in the law or our published
regulations,this determination may be relied upon for a period not to exceed five years from the date of this notification.
X There are no waters of the U.S.,to include wetlands,present on the above described project area which are subject to the
permit requirements of Section 404 of the Clean Water Act(33 USC 1344). Unless there is a change in the law or our
published regulations,this determination may be relied upon for a period not to exceed five years from the date of this
notification.
X The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act
(CAMA). You should contact the Division of Coastal Management in Wilmington,NC to determine their requirements.
Placement of dredged or fill material within waters of the US,including wetlands,without a Department of the Army permit may
constitute a violation of Section 301 of the Clean Water Act(33 USC§ 1311). Placement of dredged or fill material,construction or
placement of structures,or work within navigable waters of the United States without a Department of the Army permit may
constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act(33 USC§401 and/or 403).If you have any questions
regarding this determination and/or the Corps regulatory program,please contact Gary Beecher at(910)251-4694 or
Ga ry.H.Beecherna,usa ce.a rmv.mil.
C. Basis For Determination: There are no Jurisdictional 404 wetlands or Jurisdictional Waters of The U.S.on this
project site.
D. Remarks:
E. Attention USDA Program Participants
The delineation included herein has been conducted to identify the location and extent of the aquatic resource boundaries and/or the
jurisdictional status of aquatic resources for purposes of the Clean Water Act for the particular site identified in this request.This
delineation and/or jurisdictional determination may not be valid for the Wetland Conservation Provisions of the Food Security Act of
1985,as amended.If you or your tenant are USDA program participants,or anticipate participation in USDA programs,you should
discuss the applicability of a certified wetland determination with the local USDA service center,prior to starting work.
F. Appeals Information for Approved Jurisdiction Determinations(as indicated in Section B.above)

Subject: Request for Additional Information
Stormwater Project No.SW8 220711
Heartsease at Calabash
Brunswick County
Dear Mr. Coleman and Mr.Willis:
The Wilmington Regional Office received and accepted a Express State Stormwater Management Permit
Application for the subject project on July 18,2022,with additional information requested on July 29,2022 and
received on August 5,2022. A preliminary in-depth review of that information has determined that the
application is not complete and that additional information is needed.. To continue the review,please provide the
following additional information in a single,hard coup submittal package:
1. 15A NC.AC 02H.1053(5)(a):
a. It was noted in the response letter that forebay 1 receives 90%of the drainage area to SCM 1A,
however,the drainage areas to each forebay were not provided. Please provide the drainage areas
in square feet to each individual forebay.
b. Based on the information that forebay 1 receives 90%of the drainage area,it appears that forebay
1 is undersized. Please provide forebay calculations supporting that forebay#1 will remain
between 15 to 20 percent of the provided main pool volume based on the weighted average of its
proposed respective contributing drainage areas.
c. It was noted in the response letter that forebays 2 and 3 will be oversized due to construction
constraints. Please provide forebay calculations for forebays 2 and 3 supporting the forebay
volume percentage of the provided main pool volume based on the weighted average of their
proposed respective contributing drainage areas.Please update the narrative to provide this
justification and documentation of the oversized forebays.
2. 15A NCAC 02H.1042(2)(a)(iv), .1001(1)(c),and.1002(8): It appears that there is proposed BUA within
the right-of-way that is not currently included in a drainage area. Any right-of-way improvements
proposed for the development of this site are considered part of the common plan of development must be
included and accounted for in this project. Options for including these improvements in the application
package are:
a. Collect and treat the proposed built-upon area or an equal amount of existing built-upon area;
b. Demonstrate these improvements meet the requirements of a low density project per.1003(1)
and .1003(2),or
c. If these other options cannot be met and the improvements are minimized,meet the DOT toolbox
options,and bypasses the provided collection system,then the right-of-way built-upon area can
be quantified in a separate drainage area in Section N.10 of the application. Please also update

Dear Ms. Edmonds,
We are writing this letter in response to comments dated July 29,2022. Each of the comments are repeated
below,followed by our response.
1. 15A NCAC 02H.1042(3)(b):
a. Please provide the surface area at the temporary pool elevation for both SCMs in the
calculations in order to confirm the provided volume.
b. Rows 26,27, 35 in the wet pond supplement are not consistent with the calculations. Please
update this information to be consistent across all application documents.
c. For SCM 1 the permanent pool,vegetated shelf, and temporary pool elevations are not
presented consistently across the plans, supplement,and O&M. Please ensure this
information is presented consistently.
A)Surface areas at temporary pool are now in the runoff storage volume information tables.
B)Row 26 refers to main pool area only. The SWMP narrative and construction drawings call
out total normal pool area for proper instruction to the contractor.Rows 27 and 35 have been
corrected.
C)The documents have been revised for consistency.
2. 15A NCAC 02H.1053(1) and .1050(1): For SCM 1, the application and supplement list the drainage area
and impervious area as 29.30 acres and 13.43 acres, however, the calculations report 29.30 acres and
9.88 acres. For SCM 2,the application and supplement list the drainage area and impervious area as 9.44
acres and 3.37 acres, however,the calculations report 9.42 acres and 2.55 acres. Please:
a. Update the package to ensure the drainage area and impervious area are consistent across all
application documents.
b. Please confirm the minimum required volume is calculated based on the design condition and
ensure it is reported consistently, including in the calculations and Row 2 of the wet pond
supplement.

c. Please confirm that the SA/DA ratio reflects the design condition and ensure it is reported
consistently.
A)SCM 1 drainage areas have been revised for consistency of 13.43 acres BUA. SCM 2 has
been revised for 3.37 acres BUA.
B)Minimum water quality volumes are reflective of the impervious areas listed above.
C)SA/DA calculations are reflective of the BUA listed above.
3. 15A NCAC 02H.1053(2):
a.The average depth for SCM 1 is reported as 5.5 in the calculations, however, it is listed as 4 in
the wet pond supplement.The average depth for SCM 2 is reported as 6 in the calculations,
however, it is listed as 4 in the wet pond supplement. Please update the package to ensure
this information is presented consistently, including Rows 28-31 of the wet pond supplement.
b. In the average depth equation for SCM 1,the volume of the main permanent pool is listed as
293,209 cf, however, it is listed as 331,495 cf in the stage storage table in the calculations and
261,662 cf in the wet pond supplement.The surface area of the permanent pool is
inconsistent when comparing the calculations to Row 26 of the wet pond supplement. Please
ensure this information is presented consistently.
Average depth calculations have been updated for consistency.
Storage volume calculations have been revised.
4. 15A NCAC 02H.1053(3):The pond and forebay bottom elevations as well as the sediment storage
elevations for both SCMs are presented inconsistently throughout the application documents,
including in the Operation & Maintenance Agreement,the Wet Pond Supplement, plan sheet C9.06,
and the stage storage table in the calculations. Please confirm these elevations are presented
consistently throughout the application package.
Elevations have been revised for consistency.
5. 15A NCAC 02H.1053(5)(a):
a. Please demonstrate that the forebays for SCM 1 have been sized appropriately for their
respective contributing drainage areas.
b. SCM 1 forebay sizing information lists the forebay volume as 51,726 cf, however,summing
the volumes of the forebays in the stage storage tables results in around 59,000 cf.SCM 2
forebay sizing calculations report the forebay volume as 24,476 cf, however, it is listed as
33,590 cf in the stage storage table. Please ensure the forebay volume is reported
consistently throughout the calculations and in Row 32 of the wet pond supplement and
ensure that the forebay volume shall 15 to 20 percent of the volume in the main pool.
' A)The drainage area to the eastern forebay makes up±90%of the drainage area to the pond.
For constructability the western forebays were attributed extra volume so that surface area at
each elevation can feasibly be constructed.
B)Volumes in the storage tables and supplement forms have been revised.

6. 15A NCAC 02H.1053(3) and(5):The supplement reports the clean-out depth for the forebays as 48 and
42 inches for SCM 1 and 2 respectively, which appears to relate to 15A NCAC 02H.1053(5)(d) that
indicates when maintenance activity is to occur. However,the supplement is intended to document the
design condition of the wet pond. In Row 34 of the wet pond supplement, please report the provided
sediment storage,which appears to be 12 inches.
Row 34 has been revised.
7. 15A NCAC 02H.1042(2)(a)(ix):The provided deed reports the zip code for Alvin Bryan Willis, Ill as

application.
8. 15A NCAC 02H.1042(3)(b): Please confirm the response in Row 16 of the wet pond supplement.
Row 16 has been revised.
9. 15A NCAC 02H.1042(2): In addition to mailing a hard copy of the revised Supplement-EZ, please email
a pdf of the supplement form to the email address provided below so that it can be preserved
electronically per the regulatory requirements.
An mailed PDF copy will be provided concurrently with the hard copy.
10. Due to the potentially minor nature of these comments,the express additional information review
fee has been waived.
• Thank you,this is much appreciated.
With this submittal, please find the updated Pages 2 & 3 of the main application, updated pages from the
Wet Pond O&M document, updated SCM's 1A-1B and 2 water quality calculations,and the revised signed
Supplement EZ. Finally, also included are 2 updated sets of plans for the project. Do note that we had a
few site tweaks that involved moving a row of buildings along Calpurnia Lane that slightly affected the site,
grading and drainage plans. Due to this,we have decided it was best to resubmit the entire plan set instead
of swapping out all but about 3 pages.
Let me know if you have any further questions or need anything else to process this permit.
Sincerely,
WithersRavenet

WR Project No.03210870.10
Dear Ms. Edmonds,
We are writing this letter in response to comments made during the Stormwater Express Meeting held on
July 7,2022. Each of the comments are repeated below,followed by our response.
General Comments
1. Please provide a post construction drainage area map on 24x36 that is signed and sealed.
An additional drainage area map has been included. This map also shows storm network
drainage area breaks for reference to forebay sizing.
2. SCM 18 is understood to be a conveyance structure for SCM 1A. Please revise the Application and
Supplement form to show SCM 1 only as a combined SCM 1A and 18 drainage areas.
The Stormwater Application page 3 and Supplement EZ Form have been revised.Drainage Area
1 now reflects the sum of SCM lA and 1B.
3. Please size forebays for the appropriate contributing storm network drainage areas.
The forebays have been resized.Forebay sizes were apportioned as close as possible however
to achieve the appropriate depth the forebays sizes are not linear to the area draining to them.
4. Please provide written permission to strike '3' irum the O&M cover page wet pond count and
change to'2'.Please resubmit the SCM summary page from the O&M for 2 wet ponds.
An email was provided to Jessica Edmonds for permission to make this change.
5. Add a note about delineated wetlands onsite.This may be added to the general notes sheet next to
the surface waters statement.
> This note has been revised on Sheet C0.01. See note 2 under General Notes.
6. Please add temporary elevations,forebay berm elevations,and forebay cleanout elevations to either
the SCM profiles or typical wet pond detail.
Temporary pool elevations have been added to C9.01, C9.02, and C9.05. Forebay berm
elevations and forebay cleanout elevations have been added to C9.06 as a table adjacent to the
typical wet pond grading detail.
Stormwater Permit Application
1. Please add"Manager"to Ellis'name on the application.
Manager has been added on Page 2 of the application.

2. Please use the Owner's full name"Alvin Bryan Willis III".
The Owner name has been revised on Page 2 of the application.
3. Please revise page 3 to count'2'wet ponds in the Project Information Item 1.
Page 3 has been revised.
Supplement EZ Form
1. Revise the cover sheet to count 2 wet ponds,and include designer contact information.
The cover page has been revised.
2. Please clarify if there is a retaining wall on SCM 2(General MDC Row 6).
There is no retaining wall on SCM 2,and Row 6 has been revised.
3. Please clarify the drawdown method on each SCM (General MDC Row 9).
All ponds will need pumped,Row 9 has been revised.
4. Please specify the species of turf to be used(Wet Pond MDC Row 53).
Centipede has been specified for the slopes down to the vegetated shelf on each pond.
5. Please clarify the forebay volume for SCM 1 (Wet Pond MDC Row 33).
The forebay volume for SCM 1 has been revised. The percentage of forebay to main pool has
been updated to 20.3%. For a sandy environment we expect the forebays to see higher
sediment loads and suggest allowing the minor overage of forebay volume to be allowed.
6. Please include forebay depths at entrance and exit(Wet Pond MDC Row 43 and 44).
Forebay depths have been revised.
Stormwater Management Plan
1. Please match main pool and forebay depths in the SCM sizing calculations spreadsheet.
Forebays have been designed with depth needed to achieve±20%volume of main basin.All
pools are graded deeper to balance earthwork. Elevations found on the calculation sheets
dictate minimum design elevations,areas,and volumes to meet MDC.
2. Please revise volume calculations to start at top of sediment storage for the main basin and torebay.
Top of sediment storage has been zeroed per Express Review discussion.
Please find with this submittal,2 copies of the updated full size drainage area map,updated wet pond design
for SCM's 1A,1B&2 to insert into the previously submitted SWMP,updated pages 2&3 of the stormwater
application, updated signed supplement form, Updated SCM O&M pond elevations page. Also included is
2 updated full plan sets due to 3/of the plans being updated per our revisions. The sheets updated include
C0.01,C4.00-C4.01,C5.00-05.01,C6.00-C6.05,C6.07,C9.00-C9.06, L2.00,&Cover.
If you have any further questions or need anything else pertaining to this submittal,please let me know.

All,
Thank you for choosing to use the Express program. The Express-:submittal meeting is currently scheduled
for July 7,2022 at with Jessica Edmonds.However, this date and time is subject to change due to unforeseen
circumstances such as office closure or illness. All permit application materials need to be received in the Wilmington
Regional Office at least 2 business days PRIOR to the scheduled meeting(COB July 5,2022)to allow for administrative
processes.Due to Covid19 restrictions,please arrange for a virtual submittal meeting with screen sharing of the plans
and application materials so that we may discuss the project.
Please remember that the stormwater express program requires the following:
1. The project is eligible for the express process and is not excluded as described in the 2nd footnote of the express
stormwater fee schedule.
2. The owner or an employee of the owner who is knowledgeable in the project such as a regional manager or
project manager(but not the consultant)attends the express submittal meeting.
3. A submittal package that includes:
a. Originally signed and notarized application forms (copies or unsigned forms are not accepted). Please
note new SCMs or SCMs that are increasing in size are required to use the latest version of the
Supplement EZ and O&M EZ form available on the design manual website. SCMs that are not increasing
in size should complete the archived supplements to the best of their ability;
b. The person signing the application forms needs to meet the requirements in .1040;
c. Application fee ($4000); and
d. The submittal requirements in .1042
e. If a modification to an existing permit, a complete set of plan sheets (not just the revised pages),if
possible.

Storm water Express Review Narrative
eabasi Persimmon Road
T Cwr,cF Ca a' a 'h, NC
The purpose of this project is to develop a wooded parcel for residential use. The subject parcel is
located off Persimmon Road,adjacent to the Saltaire residential development and approximately one
mile south of Ocean Highway W (US-17). The subject parcel is completely wooded in its existing
condition and is proposed to be developed with a combination of residential units,amenity buildings,
and open space areas with the appropriate stormwater control measures (SCM's) to accommodate
this development.
The proposed SCM's consist of three wet detention ponds that are intended to provide stormwater
treatment to offset the proposed development. The subject parcel in its existing condition ultimately
drains to Persimmon Swamp (Classification C;Sw), which drains to Shingletree Swamp, a part of the
Lumber River Basin via channels surrounding the parcel. The channels along the south and west of
the property drain to the NCDOT ROW, and the channels along the east and north of the property
drain north between residential parcels.
Please note that the legal description of the parcel stares an area of 39.92 acres, however; the
surveyed boundary of the parcel is 40.43 acres, and this area shall be used in all stormwater
calculations and supporting documentation.
S tormwater Treatment Area Justific
As noted, the proposed residential development will provide three wet detention pond SCM's to
control both the quantity and quality of the stormwater leaving the subject parcel. The SCM's will
outfall to the existing channels to the north and south of the property, which both drain north to
Persimmon Swamp.
• The development proposes approximately 20 acres of impervious area comprising of
residential units, garages,sidewalks, roadways,and impervious portions of the amenity areas.
This brings the impervious percentage of the site to approximately 50%.
Please see the attached vicinity map and site plan exhibit for project location and proposed
development plan.
Adjacent Property
Land use in the vicinity of the project includes undeveloped wooded land that has been subdivided
for future residential use to the east, as well as existing residential parcels to the north, west, and
south.
