STATE OF NORTH CAROLINA
DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES
DIVISION OF ENERGY, MINERAL AND LAND RESOURCES
STATE STORMWATER MANAGEMENT PERMIT
HIGH DENSITY SUBDIVISION DEVELOPMENT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North
Carolina as amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
CBR Wilmington, LLC
Adams Landing
4728 & 4800 Carolina Beach Road, New Hanover County
FOR THE
construction, operation and maintenance of one (1) wet detention pond in compliance with the
provisions of 15A NCAC 2H .1000 and Session Law 2008-211 (hereafter separately and
collectively 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 and considered a part of this permit.
This permit shall be effective from the date of issuance until June 10, 2022 and shall be subject
to the following specified conditions and limitations:
I. DESIGN STANDARDS
1. This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data.
2. This stormwater system has been approved for the management of stormwater runoff as
described in Section 1.7 of this permit. The runoff from all built-upon area within the
permitted drainage area of this project must be directed into the permitted stormwater
control system. The wet pond has been designed to handle the runoff from 209,237
square feet of impervious area.
3. The subdivision is permitted for 42 lots, each allowed a maximum of 3,300 square feet of
built-upon area.
4. The maximum built-upon area allowed for the entire subdivision is 209,237 square feet.
5. The project shall provide and maintain a 50' wide vegetative buffer adjacent 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.
Page 2 of 9

State Stormwater Management Systems
Permit No. SW8 140321
6. Based on this plan and design submitted to DEMLR, the elevation of the permanent pool
is set at 10.5 fmsl, the elevation of the temporary pool is set at 11.92 fmsl, the outlet
invert elevation is 10.0 fmsl, the elevation of the downstream discharge point is 9.5 fmsl,
and the highest elevation of the adjacent wetland is 11.0 fmsl.
a. The difference in the elevations between the permanent pool and the nearby
wetlands indicates that the pond will not dewater the adjacent wetlands.
Additionally, the downstream elevations and conveyances, as demonstrated on
the plans, are at an elevation lower than the outlet pipe, allowing the pond to
function adequately to release the required storage volume within the specified
drawdown time.
b. A site specific soil evaluation was not provided for this project. Without a site
specific soils evaluation, the seasonal high water table and/or groundwater
conditions are unclear in the location of the wet pond; therefore this wet pond
may not be able to sustain its permanent pool level. Please note that this may
cause the wet pond to become dry between storm events which may endanger
the health of the vegetation on the vegetated shelf or incoming groundwater may
maintain a pool level that prevents the required storage volume from being
available and preventing the runoff from discharging within the specified
drawdown time. Therefore, the designer is responsible for:
1. Providing DEMLR with a certification and survey showing the pond meets all
approved design criteria and elevations as noted in the plans and this
permit.
2. Ensuring that the owner is aware that: (a) the pond may dry out between
storms and that, (b) a healthy stand of vegetation must be maintained on the
vegetated shelf.
c. If, in the future, this design is not found to meet the intent of the stormwater rules
or does not provide the required design elements, then modifications to the
stormwater system, including the pond design, will be required.
7. The following design elements have been permitted for this wet detention pond
stormwater facility, and must be provided in the system at all times.
a. Drainage Area, acres: 8.57
Onsite, ft2: 373,431
Offsite, ft2: 0
b. Total Impervious Surfaces, ft2: 209,237

High Density Residential Subdivisions
Deed Restrictions & Protective Covenances
In accordance with Title 15 NCAC 21-1.1000 and S.L. 2006-246, the Stormwater Management Regulations,
deed restrictions and protective covenants are required for High Density Residential Subdivisions where
lots will be subdivided and sold and runoff will be treated in an engineered stormwater control facility. Deed
restrictions and protective covenants are necessary to ensure that the development maintains a "built-upon"
area consistent with the design criteria used to size the stormwater control facility.
I, James C. Walker—, acknowledge, affirm and agree by my signature below, that I will cause the following
deed restrictions and covenants to be recorded prior to the sale of any lot:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number -:! /y 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. n E C E WU
4. The covenants pertaining to stormwater may not be altered or rescinded with the express yur'tte
consent of the State of North Carolina, Division of Water Quality. il MAR 7 U.2UW
5. Alteration of the drainage as shown on the approved plan may not take place gout the concurre ce
of the Division of Water Quality.
6. The maximum allowable built-upon area per lot is 3300 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, gravel, brick, stone, slate, coquina and parking areas, but does not
include raised, open wood decking, or the water surface of swimming pools.
7. Each lot will maintain a 50 foot wide vegetated buffer between all impervious areas and surface waters.
8. All runoff from the built-upon areas on the lot must drain into the permitted system. This may be
accomplished through a variety of means including roof drain gutters which drain to the street, grading
the lot to drain toward the street, or grading perimeter swales to collect the lot runoff and directing them
into a component of the stormwater collection system. Lots that will naturally drain into the system are
not required to provide these additional measures.

Subject: RE: Adams Landing
I just finished revising the pond planting schedule. I was referring to the BMP manual and it states the rule of thumb is
24" to 36" spacing for plantings on the shelf. I split the difference and called for a 30" spacing. If you actually lay this
out, it yields about 25 plants per 200 square feet (which works out to 1 plant per 8 square feet). There is a discrepancy
in the manual, as it calls for 50 plants per 200 square feet, which works out closer to the 24" spacing
recommendation. My experience is that most vegetation maintenance problems below the side slopes involve the pond
being overgrown. Given this, I am more comfortable using the 30" spacing and I am satisfied that it meets the intent of
the manual.

I'll update the cross section and get you the proper vegetated shelf planting schedule.
The 12' wide channel is the rip rap apron downstream of the outfall pipe FES. You asked me to substantiate the runoff
velocity, that is it. The 70' wide channel is the emergency overflow weir that is designed to carry the 100' year
storm. DENR doesn't regulate the velocity of this one.
The spreadsheet uses the manning equation to calculate the required trapezoidal channel dimensions for the
anticipated flow. The variables are reported in the spreadsheet. They are: longitudinal slope, bottom width, side slope,
roughness coefficient, and flow depth.
There is a lot of information on the manning equation out there. A link to a concise tutorial can be found here:

Luke,
It appears that we don't have a copy of Sheet 12 which you say has the planting schedule for the vegetated shelf. Also,
there is no reference about the vegetative shelf on the cross-section shown on Sheet 11. It only references the ground
cover. Please revise.
Also, on your calculation page, how do you get the bottom width measurement for your runoff calculation for 10 and
100 year storms? 12 &70?

Dear Steve,
Please find the attached stormwater management plan with revisions per your 4/2412 0 1 4 1etter. I have attempted
to address your concerns as follows:
1. I have attached a copy of the unsigned wetland map along with the Jurisdictional Determination.
The proposed acceptable vegetation types,seeding rates,planting dates and soil preparation techniques
are detailed in the site stabilization schedule found on sheet 12. The pond cross section refers to this
schedule. iJo �'/ `"� �—
1(SG�M�rrr�� /V 0� �/ df-S. .14„6l`t`
I have added a section to the calculations that reports the flow over the outfall apron during the peak
pond discharge of the 10 year storm. The velocity is less than 2 feet per second. This calculation is
flagged for quick reference. ?n
4. There are no streams on or adjacent to the site.
5. There are no streams on or adjacent to the site and the pond outfall is designed to flow at a velocity not
to exceed 2 feet per second during the 10 year storm.
6. The permanent pool is designed with due consideration given to the elevation of the receiving ditch
and the elevation of adjacent wetlands. Refer to my email to you dated 4/29/2014.
7. Refer to 96.
8. 1 have darkened the pond drainage area line on sheet 4 to differentiate it from the curb inlet drainage
area lines.
9. The critical pond contours are labeled on the detail. Please refer to the pond schedule for elevations.
10. 1 have dimensioned the major elements of the permanent pool. This should be sufficient to illustrate
the pond size. The construction layout will be accomplished by means of a survey due to the intricate
shape and proximity to wetlands.
11. I have attached an initialed page 5 of the application.
Thank you for your prompt attention to this matter. Please let me know if you have any additional questions
regarding this project.

Steve,
Per your 4/24/14 comment letter and our phone conversation today, please find the attached color exhibit showing the
relationship of the pond,the wetlands, and the existing ditch. The point of this exhibit and following email is to
demonstrate the appropriateness of the specified 10.50' permanent pool elevation (PPE) with respect to the existing
adjacent features. My experience has been that, unlike infiltration-based BMPs,SHWT determinations are only required
for wet ponds when the designer and/or reviewer is concerned that either the pond will not drain enough, the pond will
drain too much, or adjacent wetlands are located such that they will be drained by the pond. As you will see, I have
given due consideration to the selected PPE and would ask that you reconsider the request to the provide a soil
report. It is an unnecessary cost to the applicant and can only serve to compromise a design that I have given significant
thought to and am willing to stand behind.
When determining the PPE of the wet pond, the following criteria were considered:
1. Does the elevation and condition of the receiving ditch(or stream, storm drain, low area,etc.)allow the pond
to draw down to the selected PPE in 2-5 days?
Failure to draw down could result in reduced treatment volume and/or flooding. This pond is adjacent to a ditch
with an invert elevation of about 8.5' at the pond outfall and positive drainage is provided all the way to
Barnards Creek. The pond will draw down to the PPE and will not be held up by downstream conditions. The
design pond storage volume will not be affected. This problem often occurs when ponds discharge to isolated
low areas that tend to remain flooded for and extended period after a rainfall.
2. Will the selected PPE result in the draining of adjacent wetlands or otherwise create a dewatering effect that
is undesirable?
The elevation of the adjacent wetlands varies from 9.5' to 11' alongside the pond. The selected PPE effectively
mirrors this elevation. The elevation of the existing ditch that runs through the middle of the wetland varies
from 7.5' at the northwest end of the pond to 9.5' at the southeast end of the pond. To generate a wetland
dewatering effect greater than the ditch,the PPE would have to set below the elevation of the ditch. Of course,
then the pond would not be functioning correctly per criteria #1.
3. Will the pond hold water at the selected elevation during expected dry periods?
The presence of the existing ditch, which has an elevation that varies from 7.5' at the northwest end of the
pond to 9.5' at the southeast end of the pond, will create a condition that drops surrounding static groundwater
elevations during dry periods. If the water drops more than 0.5' below the design PPE, the resulting shoal that
develops is hard to maintain, the moisture sensitive vegetation dies,the shoal attracts geese, and the design
depth is compromised resulting in unwanted vegetation in the center of the pond and potential thermal
pollution.
Considering all of the site specific factors, a PPE of 10.50' was selected. Any lower and the pond would not drain and the
wetland would be dewatered. Any higher and the pond would dry up between rainfall events. Either consequence is
undesirable from both a water quality and site maintenance perspective. If there was any doubt about the hydraulics at
this pond site, I would suggest to the applicant to investigate further. Due to the presence of the ditch and the
wetlands, there is a very narrow window where the PPE can be.

Again, please take my thought process into consideration. It is not something I take lightly. My goal is to provide you
with the additional information and revisions you've requested though the course of this week to enable you to
complete your review.

Adams Landing
New Hanover County
Dear Mr. Walker:
The Wilmington Regional Office received and accepted a State Stormwater Management Permit
Application for Adams Landing on March 20, 2014. A preliminary in-depth review of that information
has determined that the application is not complete. The following information is needed to continue
the stormwater review:
A Please submit a copy of the wetlands delineation map signed by the Corps of
Engineers or at least provide a copy of the un-signed delineation map submitted to
the Corps for approval.
Please specify the vegetation types to be planted on the side slopes of the BMP and
the wetland species to be planted on the 10:1 vegetated shelf of a wet pond. Be sure
that the landscape plan includes a calculation of the square footage of shelf area and
the minimum number of wetlands plants - 50 for every 200 square feet of shelf area.
Do not plant trees within 10 feet of inlet or outlet pipes, spillways or flow spreaders.
Tree species with water-seeking roots such as weeping willows and poplars, should
be avoided within 50 feet of pipes or manmade structures. Evergreen trees which
produce relatively little leaf-fall are preferred in areas draining to detention devices.
Trees should be set back so that branches do not extend over the permanent pool.
All runoff that is directed to flow through any 401/404 wetlands shall flow into and
through the wetlands at a non-erosive velocity, which is based on the peak flow from
the 10 year storm. Please provide calculations showing the velocity of flow for such
storm through outlet pipe FES2.
14. All intermittent and perennial streams must have a 50' surface water buffer. Please
ishow on the plans if applicable.
. All discharges into the surface water buffer must provide and maintain diffuse flow
through the buffer. This can be accomplished by the use of level spreaders or other
equal measures.
I6. A soils report for all engineered systems and curb outlet swale systems is required.
The report should contain the estimated Seasonal High Water Table (SHWT)
elevation at each proposed BMP location reported in FMSL, not as a depth Below
Existing Ground (BEG). If it's reported as a depth BEG, the bore map must include
the existing ground elevation at each bore location.
17. Please note the SHWT on the pond section detail.

Project: PW-1061

Date: 3/14/2014
Adams Landing--Project Narrative
Introduction
The site is located at 4728 and 4800 Carolina Beach Road in New Hanover County. A total of 42 single family homes are
currently proposed on approximately 11 acres located near the intersection of Silver Lake Road and Carolina Beach Road.
The site presently contains a few trailers as well as an older stick built home—all of which are to be removed along with
associated driveways and utilities. The front of the site is densely wooded with intermediate sized pine trees,with some
hardwoods located towards the rear of the site. Property to the northeast and southwest are underdeveloped,with
structures complimenting those on the subject site.
Roadways
The site will feature a single access point to Carolina Beach road. An existing median in Carolina Beach road will limit
ingress and egress to right turn movements.A right turn lane is proposed along Carolina Beach Road as a means to
provide safe ingress.
Roads internal to the project will be designed in accordance with NCDOT road standards and dedicated a public.The
roads will feature curb and gutter with a piped stormwater collection system. A right of way will be reserved between Cut
De Sac 2 and the adjoiner to the south as a means to provide future connectivity.
Utilities
The site will be afforded water and sewer by CFPUA. Extension of the existing mains will be required to provide service
to the 42 proposed residences. A doghouse manhole will be constructed on an existing gravity sewer main and a total of
1,530 If of new 8"gravity main will be installed. Each of the 42 proposed lots will be served by gravity services. An
existing water main will be extended from a point in the shoulder of Carolina Beach Road 435' south of the project along
the site frontage and internal the project. Provisions will be made for future extension of the water main at the provided
roadway stub out. Blow offs will be provided at the terminus of each main. Hydrants will be provided within the
subdivision per CFPUA spacing requirements. A total of 850 If of 8"water main will be installed in the Carolina Beach
Road right of way. Internal to the project,990 If of 6"water main and 545 If of 2"water main will be installed.
Stormwater
The site currently drains from Carolina Beach Road towards an unnamed tributary of Bamards Creek that forms the
southwest boundary of the site. Runoff will be collected by curb and gutter with a piped stormwater collection system and
routed to a wet pond for treatment and detention satisfying NCDENR and New Hanover County requirements. The
project will be permitted as high density with an overall BUA of 42%.
Approximately 17,500 sf of existing impervious surface is to be removed from the site. This BUA is comprised of the
existing stick built residence and its accessory structures,4 mobile homes,and a gravel road.
Erosion Control
All areas of the site which are subject to improvements will be cleared and graded to establish desired drainage patterns.
Silt fence will be used to contain sediment around portions of the site which will drain towards adjoining property or
existing roadways. Curb inlets will be protected with traditional hardware cloth and stone protection. Shallow swales will
be used to direct drainage to a proposed temporary sediment basin which will later be cleaned out and utilized as a wet
pond. Temporary sediment traps will be used to treat the runoff from two swales that direct runoff from small areas of the
site to an existing ditch along the southeast perimeter. A stone construction entrance will be used at the proposed
driveway.
