Dear Mr. Kirkman:
JA/-0/k d
A Division of Energy, Mineral, and hand Resources file review has determined that
Stormwater Permit SV 7060904 for a stormwater treatment system consisting of two
wet detention ponds serving Carolina Colours — Amenity Campus located on
Waterscape Way, New Bern, NC expires on November 22, 2020. This is a reminder that
permit renewal applications are due 180 days prior to expiration. We do not have a
record of receiving a renewal application. It appears that the property has been sold. If
property is sold, stormwater permits are not automatically transferred.
Please submit a completed permit renewal application and ownership change
application along with a $505.00 fee for permit renewal. Also, it was noted in the file
review that a designer's certification that the project was constructed in accordance with
the approved plans as required by the permit has not been submitted. Please include
this with your application. Permit application forms for renewal can be found on our
website at:
hops:/T /dea.nc.govjaboutLd vises ergy�eralland-resourcees_/ent gy-mineral later
rules/stormwater-oroaram/imst-construction. North Carolina General Statutes and the
Coastal Stormwater rules require that this property be covered under a stormwater
permit. Failure to maintain a permit subjects the owner to assessment of civil penalties.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application form. You can request a copy by e-mailing me at roger.thorpea—ncdenr.gov.

Eric,
to follow up on our phone conversation about the Carolina Colours - Amenity
Campus. I just needed to set a deadline date that I'm sure will not be an issue
with the 2 minor items (adding pipe #10 and the swale back to the plans)
needed to make the stormwater application complete.
Can you please have the two revised copies of plan sheet 4 to me by

This letter is in response to your letter to Mr. Kenneth 1. Peregoy dated September
27, 2006. Please note that the plan has been revised to eliminate the bioretention
areas, so the items (2,3 and 5 thru 10) in your letter pertaining to bioretention
areas will not be addressed.
1) The soils report gives the existing groundwater level at the time of the Borings
around S feet below ground elevation, but this does not reference the expected
seasonal high water table. .The soils report should include at a mininnim the
date of the borings, a map of the boring locations, soil profiles of the borings,
the expected infiltration rate of the in -situ soils, and the expected seasonal
high water table. Site boring logs have much of this information and can be
included with the report. Please also have the report reference the soils fotutd
and if they are consistent with the soils found in the Craven County Soils
book. Please include the soils map from the book with site located.
The site boring logs are attached. The soils found on site are generally consistent
with those cited in the Soil Survey of Craven County. A map of the soils with the
site located is attached. According to the soil survey the expected rate of
infiltration for Grantham soils in the top 0-10 inches is 2.0 to 6.0 inches per hour
and from 10 to 72 inches of depth the expected rate of infiltration is 0.2 to 0.6
inches per hour. According to the soil survey the expected rate of infiltration for
Exum soils in the top 0-11 inches is 2.0 to 6.0 inches per hour and from I 1 to 60
inches of depth the expected rate of infiltration is 0.2 to 0.6 inches per hour.

4) Please state in the permanent seeding specifications what the vegetated cover
for the swales, grassed filter cl<- other sloped areas should be. (Cordgrass is
the only grass type specifier) in the pernianent seeding specifications.)
The seeding specifications have been revised please see Sheet 8 of the plans.
11) Please explain how access is provided to the outlet orifice to check for
clogging and how it can easily he maintained. (It seems that there may be
little to no niaintenance performed on the orifice if access is only by boat and
one foot under water.) A typical outlet detail is attached that allows for easier
inaintenance to be performed.
The outlet structure for the ponds has been change to match the detail you
provided. Please see Sheet 9 of the plans.
12) Please reduce the spacing for the trash guard on the overflow spillway froni
10 " bars to 4 " grated openings or less_
Due to the change in the outlet structure, the spillway will not be used as a
principal spillway, but an emergency spillway. Therefore no trash guard is
required in the spillway.
13) Please specify what occurs with the 8 " outlet pipe front the wet detention
pond as it drains West. Does it continue to be piped off -site to aClloining
property? What does it outlet into and does it need an energy dissipater to
help reduce erosion?
The outlet structure for Wet Detention Pond 42 has been revised per your
suggestion and there is no longer an 8" outlet pipe. The 15" pipe from the
modified outlet structure empties into a ditch along the adjoining property line.
The drawing has been revised to clearly define the ditch. A riprap energy
dissipater has been designed at the outlet to reduce erosion.
14) Please do not forget to have plans, calculations, supplements, narrative, etc.
revised, signed, sealed and dated as necessary when re -submitting.

Eric,
Yes a pond would eliminate items 2, 3 & 5-10 completely, just remember that these should
be included on future projects proposing bioretention areas.
Item 1 should still be included and a copy of the boring logs
should be included and referenced. A reference can be made to
the existing report (with boring logs attached) in a revised narrative to explain
how permanent pool elevations were determined and if the soils
found on -site match the soils shown in the County soils book.
An extension until Oct. 13, 2006 for submittal is granted.
GThanks, _

Footnotes:
When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 The requirement for a vegetative filter may be waived if the wet detention basin is designed to meet 90% TSS removal.
11. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices manual
(N.C. Department of Environment, Health and Natural Resources, November 1999) and Administrative Code

k. A recorded drainage easement is provided for each basin including access to nearest
�%�,r•�r`.� i right-of-way.
1. If the basin is used for sediment and erosion control during construction, clean out of
the basin is specified prior to use a wet detention basin.
m. A mechanism is specified which will drain the basin for maintenance or an emergency.
III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the
vegetated filter if one is provided.
This system (check one) (❑) does (®) does not incorporate a vegetated filter at the outlet.
This system (check one) (❑) does (Fkl) does not incorporate pretreatment other than a forebay.
Form: SWU-102 Rev. 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs
within 2 to 5 days as designed.
2. Repair eroded areas immediately; re -seed as necessary to maintain good vegetative cover, now
vegetative cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed
of in an appropriate manner and shall be handled in a manner that will not adversely impact water
quality (i.e. stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth
reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 20 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads ZD feet in the fore bay, the sediment shall be removed.

Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and fore bay berm.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain shall be minimized to the maximum extent practical.
7. All components of the wet detention basin system shall be maintained in good working order.

Bioretention Area Maintenance Agreement
Bioretention is a water quality practice using plants and soils for the removal of
pollutants from stormwater runoff. The following are maintenance guidelines for
bioretention areas.
Inspect monthly, or after every runoff -producing rainfall event:
i. Remove debris from the bioretention area
ii. Check and clear the piping of any obstructions.
iii. Check the area side slopes; remove trash, repair eroded areas before next
rainfall.
11. Quarterly
Inspect the collection system for proper functioning. Clear accumulated
trash from basin grates and basin bottoms, and check piping for
obstructions.
ii. Reseed grassed swales, including the vegetated filter if applicable, twice a
year as necessary. Repair eroded areas immediately.
III. Every 6 Months
i. Remove accumulated sediment from the bottom of the outlet structure.
ii. Remove any sediment build up in the bioretention area.
iii. Apply an alkaline substance, such as limestone. Testing of the pH of the
organic layer and soil should precede the limestone application to
determine the amount of limestone required.
IV. General
i. Mow the side slopes according to season. Maximum grass height will be
6".
ii. All components of the bioretention pond system must be kept in good
working order.
iii. Plant material upkeep includes addressing problems associated with
disease or insect infestations, replacing dead plant material and any
necessary pruning.

Amenity Campus
Stormwater Management Plan
New Bern, North Carolina
August, 2006
Introduction:
The proposed Amenity Campus is a 17.0 acre project sited on Waterscape Way at the
intersection of Waterscape Way and Wilcox Road (SR 1110) at the Carolina Colours
Subdivision in New Bern, North Carolina. The site varies in elevation from
approximately 25' above msl to 15' above msl. Soils consist primarily of Grantham silt
loam, hydrologic group D, and Exum silt loam, hydrologic group C.
The Stormwater Management Plan has three goals.
1. Remove 85% total suspended solids.
2. Reduce the total nitrogen export to below 10 lb/ac/yr, at which point a fee can
be paid based on the difference between the total nitrogen export and 3.6
lb/ac/yr.
3. Reduce the peak flow from the post developed site to predeveloped levels for
the I year and 10 year SCS TR-20 Type III Storm.
Bioretention Cells:
According to the NCDENR "Stormwater Best Management Practices" Manual
Bioretention cells achieve a removal rate of 85% for total suspended solids, thus
addressing the first goal. Bioretention areas are intended to address the spatial constraints
that can be found in intensely developed urban areas where the drainage areas are highly
impervious. Bioretention is a water quality practice using plants and soils for the removal
of pollutants from stormwater runoff.
Three bioretention cells have been incorporated into this plan. Please see the calculations
for sizes and drainage areas. The bioretention areas were sized to treat the runoff from
the area draining to them and collect the runoff in underdrains after it has slowly filtered
through the soil. The splitter boxes in Bioretention Cells #1 and #2 have their overflow
weirs set approximately 9 inches above the bioretention area. The splitter boxes act as
overflow spillways and redirect any runoff in excess of the one inch storm away from the
bioretention cell. The weirs in the splitter boxes are sized to attenuate the I and 10 year
storms to predevelopment levels for the individual drainage areas.

Wet Detention:
According to the NCDENR "Stormwater Best Management Practices" Manual, wet
detention ponds achieve a removal rate of 85% for total suspended solids, thus addressing
the first goal. Wet detention ponds slow stormwater runoff and allow solids to settle.
Plug flow is assumed for wet detention ponds.
One wet detention pond has been incorporated into this plan. Please see the calculations
for size and drainage areas. The wet detention pond was sized to treat the runoff from the
area flowing to it based on the NCDENR SA/DA chart for coastal counties. It was also
sized to allow sufficient storage for peak flow attenuation. A Iow flow orifice detains the
runoff from a 1" storm for two to 5 days. Larger storms pass through a spillway which
serves to attenuate the 1 and 10 year storms.
Nitrogen Export:
The runoff from Drainage Areas 1 and 2 pass through Bioretention Cells 1 and 2
respectively. The runoff is then collected and discharged through the riparian buffer via a
level spreader. The State's nutrient management programs recognize bioretention cells as
achieving a 35% reduction in nitrogen. Discharging through a riparian buffer will further
reduce the nitrogen by 30 % according to the City of New Bern's Stormwater
Management Manual. Used in series this equates to a 54.5% reduction in nitrogen for
the runoff passing through Bioretention Cells I and 2.
The runoff from Drainage Area #3 flows through the wet detention pond. The State's
nutrient management programs recognize wet detention basins as achieving a 25%
reduction in nitrogen
Using the method described in the City of New Bern's Stormwater Management Manual
the total nitrogen export for the site without using a BMP would be 8.8 lb/ac/yr. By
incorporating bioretention cells and discharging them through a riparian buffer this
amount was reduced to 4.0 ib/ac/yr. As stated in the second goal, this is below the 6
lb/ac/yr threshold. A fee is required to pay the difference between 4.0 lb/ac/yr and 3.6
lb/ac/yr.
Detention:
A computer model of the site was used to route the stormwater runoff. Drainage areas I
and 2 were combined because they are connected by pipes. The tables below show that
the peak runoff from the respective areas is at or below the predeveloped levels for the
one and ten year storms, as desired in the third goal of the plan. Please refer to the
attached drainage area map and calculations for further detail.
