Re: Covil Ave.Apartments Detention Pond
Dear Ms. Lewis,
I am submitting to you a revised set of plans of the proposed Detention Pond
addressing the items you outlined in your letter to us dated August 19, 1998. Since we
received your letter we (CHJT, P.A. and NCDENR) have had a series of discussions
concerning the geometry of the pond surface and volume. Per the fax we received from you
on August 28, 1998 we feel that the current pond design is adequate and meets the required
water quality goals set by NCDENR. Thank you for considering the interpretation we
presented to you. In addition to the geometry issue that is addressed by review comment#4
are four more comments that we have addressed in the following manner.
1) We have added an antfsiphon tube to the drawdown tube. This will allow the siphon to be
broken without increasing the outflow as modeled during the water quality drawdown.
2) The entire pond perimeter pess the dam and inside the forebay) has an aquatic shelf as shown
on the detail sheet. The dam does not include an aquatic shelf because we do not encourage
plant growth along the dam in order to prevent degradation to the earthen slopes and core.
3) The pond's permanent pool dimensions are included on the detail sheet.
4) The required flow path has been achieved.
5) A trash rack has been added to the notched weir
Please consider this letter as certification with Engineer's Seal for the enclosed information.
Otherwise we look forward to obtaining a Stormwater Management Permit for this project.
Please contact our office to discuss this project if you so desire.

Dear Jeanette:
I tried to Email you something on Tuesday, the 25th, but it came back as
undeliverable. I suppose that your new office location has upset the
system. I'll try again.
This is that 3:1 L:W ratio thing again. Ken Wrenn says that he has provided
additional surface area and volume. When I checked the file, 14,562 square
feet of additional surface area was provided, and 1,736 cubic feet of
additional volume was provided.
He said he could provide additional depth, and wanted to know how much.
I told him this was something out of the ordinary, and we didn't have hard
and fast numbers for him to provide. He seemed a little shocked that I
couldn't offer any specifics for him.
I'm inclined to trade off the additional area and volume for the reduced
flow path, in this case.

Subject: Length to Width Ratio
D&M Apartments/Covil Avenue
Stormwater Project No. SW8 980436
New Hanover County
Dear Mr. Wrenn:
Thank you for your recent request regarding the requirement for a 3:1 length to width ratio in the
detention pond. You asked that this requirement be waived because you had provided excess surface area
and volume, due to City flood requirements. You stipulated that the pond, if constructed with the minimum
State requirements for surface area and volume, would meet the 3:1 L:W requirement.
After a considerable amount of discussion and studying, it has been determined that your request to
waive the 3:1 requirement can be granted due to the fact that the pond has been oversized. Approximately
33% additional surface area and 4% additional volume has been provided, above the minimums required.
Together, these overages provide sufficient justification to grant your request to waive the 3:1 LW ratio
requirement. The proposed pond inlets and outlet must be located at opposite ends of the pond (lengthwise),
with a forebay provided for each inlet in order to permit the project.
If you have any further questions, please write them down and send them in. If I can be of any
assistance, please do not hesitate to call me at [phone].
Sincerely,

Subject: 2 nd REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 980436
Covil Avenue/D&M Apartments
New Hanover County
Dear Mr.Wrenn:
The Wilmington Regional Office received previously requested information for the Stormwater
Management Permit Application for Covil Avenue/D&M Apartments on June 18 and August 11, 1998. A
preliminary review of that information has determined that the application is not complete. The following
information i5 needed to continue the stormwater review:
1. The outlet details show a 1.5" hole drilled in the top of the 4" orifice pipe. This will
effectively make the 4" pipe act as the limiting factor instead of the 3.5" orifice specified. The
net effect will be to draw down the pond in less than 2 days. Please delete this 1.5" hole. The
plans given to me on June 18, 1998, had this 1.5" hole located above elevation 26, which was
fine because the permanent pool was at 24, and the storage elevation was at 25..
2. The revised calculation sheet again indicates that the aquatic shelf is placed "where practical".
This is not acceptable. The shelf is located under the permanent pool, so you do not lose any
required surface area by creating the shelf. Please revise the pond contours shown on drawing
SD3A to reflect a vegetated shelf around the entire pond perimeter.
3. Please place the detail drawing of the pond's permanent pool dimensions on the detail sheet.
4. The required 3:1 L:W ratio in the pond has still not been met. Additional storage is all well
and good, but it does not provide sufficient justification for having a 2.2:1 ratio. The ability
of the pond to settle the solids is contingent on providing a sufficiently long flow path, which
the State has set at 3:1. Please provide baffling, bulkheads or berms in the pond to create a
3:1 or longer flow path.
5. Please provide a trash rack for the overflow.weir at elevation 26. It doesn't do.much good to
have one only for the larger storms, when 90% of the rain events are 1" or smaller.

NARRATIVE OF STORMWATER TREATMENT AND MANAGEMENT
Introduction
The Covil Ave.Apartment Project is subject to certain watershed restrictions because the water
that leaves the site drains to surface waters that are being protected by NCDENR and the local
govemment. This project is categorized as"high density option"and is limited to 60% impervious area
with stormwater control. A wet detention pond will function as the water quality control necessary to
meet the State requirements. The wet detention pond is intended to function as designed forever. The
operation and maintenance of the Detention Pond Facility will forever be the legal responsibility of the
Owner and or Home Owners Association associated with the site. This requirement is legally upheld
by an Operation and Maintenance Agreement between the Owner and the NCDENR. The Operation
and Maintenance Agreement should be administered by a responsible party to ensure that the
objectives are met. As the Agreement dictates; routine maintenance of the Wet Detention Pond Facility
and the associated stormwater collection system should be performed to ensure continuous water
quality goals set by NCDENR. Following is a nanative of how the treatment and management goals
will be achieved.
A. Construction
Construction of the facility will conform to the Engineer's plans and specifications. All sediment that
collects in the basin during construction will be removed after the site is stabilized.
B. Basin Access
Access to the pond and forebay will be allowed for via two entry points. The parking lots will serve
as entryways to the basin. The forebay will be accessed through the space east of building 4. The
basin will be accessed through either of the aforementioned open spaces or the openspaee
between buildings 4&5. A 10'access easement measured from the top of bank of the basin will
be recorded and maintenance will be performedperiodically to ensure that access is provided as
intended.
C. Routine Maintenance
Refer to the"Operation and Maintenance Agreement"between the Owner and NCDENR.
Attiehment of iastification of requirements pertaining to Required Items Checklist of item II.of
the Wet Detention Basin Supplement Form
Item I.) A 30 ft.vegetative filter•is not provided at the outlet because the basin is sized according to
the 90%TSS'removal chart
Item m.) A recordeddtainage easement for the basin with access to the nearest right-of-way will be
provided.
Item b.) A 3:1 length to width ratio could be obtained using the minimum required pond size.
However,we have provided additionatwater quality storage than required while creating a
length to width ration of approximately 2.2 to 1. See figure one of this report for an
explanation.

Dear Ms. Lewis,
In permitting the wetland area on our site,our biologist/soils engineering company, ECS determined
that we should be able to classify our wetlands as isolated wetlands and the Corps of Engineer
consequently would have no jurisdiction. I am sending you a copy of the map and Notification of Non-
Jurisdictional Determination letter.
Please let us know if you need any further information from us.
Sincerely,

NARRATIVE OF STORMWATER TREATMENT AND MANAGEMENT
Introduction
The Covil Ave.Apartment Project is subject to certain watershed restrictions because the water
that leaves the site drains to surface waters that are being protected by NCDENR and the local
government. This project is categorized as"high density option"and is limited to 60%impervious area
with slormwater control. A wet detention pond will function as the water quality control necessary to
meet the Slate requirements. The wet detention pond is intended to function as designed forever. The
operation and maintenance of the Detention Pond Facility will forever be the legal responsibility of the
Owner and or Home Owners Association associated with the site. This requirement is legally upheld
by an Operation and Maintenance Agreement between the Owner and the NCDENR. The Operation
and Maintenance Agreement should be administered by a responsible party to ensure that the
objectives are met. As the Agreement dictates; routine maintenance of the Wet Detention Pond Facility
and the associated stormwater collection system should be performed to ensure continuous water
quality goals set by NCDENR. Following is a narrative of how the treatment and management goals
will be achieved.
A. Construction
Construction of the facility will conform to the Engineer's plans and specifications. All sediment that
collects in the basin during construction will be removed after the site is stabilized.
B. Basin Access
Access to the pond and forebay will be allowed for via two entry points. The parking lots will serve`
z_ as entryways to the basin. The forebay will be accessed through the space east of building 4. The
basin will be accessed through either of the aforementioned open spaces or the open space
between buildings 4&5. A 10'access easement measured from the top of bank of the basin will
be recorded and maintenance will be performed periodically to ensure that access is provided as
intended.
C. Routine Maintenance
Referto the"Operation and Maintenance Agreement"between the Owner and NCDENR.
Attachment of justification of requirements pertaining to Required Items Checklist of item It.of;.
the Wet Detention Basin Supplement Form
Item c.) A 2.5:1 slope is provided at the East parking lot. We ask for an amendment to the
requirements.
Item I.) A 30 ft.vegetative fitter is not provided at the outlet because the basin is sized according to
the 90%TSS removal chart
Item m.) A recorded drainage easement for the basin with access to the nearest right-of-way will be
provided.

Subject: ACKNOWLEDGEMENT OF RECEIPT AND
REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 980436
Covil Avenue / D&M Apartments
New Hanover County
Dear Mr. Wrenn:
The Wilmington Regional Office received a Stormwater Management Permit Application for Covil
Avenue / D&M Apartments on April 24, 1998. 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. Please use ink or type the information for the permit application.
'�:j 2. Please don't use odd depths for the SA/DA computation. Use only the standard depths as
G listed in the table. This pond is 5' deep, according to the elevations.
3. Detention ponds may not be located in 404 wetlands, unless a permit to fill the wetland has
been approved. Please provide a copy of the approval letter from the Corps and a 401 Water
Quality Certification, or relocate the pond out of the wetland.
/ 4. Provide a dimension plan. Include dimensions for all buildings, parking areas, walks, tennis
5" courts, recreation facilities, pool, etc.
.
�5 (;�`Sw 5. Provide details for the pond section, and outlet structure on the plans. Details need to show
the pool elevations, 6:1 vegetated shelf, forebay, outlet structure orifice and overflow, and
°\46 0)0 the emergency spillway.
15 6. Provide the dimensions for all sides and parts of the figure created by the permanent pool of
NJ Z\� Qtk the pond, including arcs, radii, and tangent sections.
R2h ` v,, 7. Provide spot elevations in various places such as high points and parking lot corners to verify
drainage into the pond.

Stormwater Project No. SW8 980436
----------------------------------------------
8. All built-upon area associated with the project must drain into the system, or provide it's own
treatment system. There appears to be a recreation area outside of the drainage area that is not
directed into the pond and does not provide a separate treatment system. Please show
proposed elevations for this area.
✓ 9. The ponds must be completed in their entirety prior to the construction of impervious
surfaces. The note on the plans that the forebays will be constructed after the site is stabilized
must be removed. You only need to clean out the forebays regularly.
10. Please seal the plans.
✓ 11. Please extend the vegetated (aquatic) shelf across the pond side of the forebay weirs and the
south bank of the pond.
hr\� L/ 12. Outlets 1 and 2 must be relocated, or the outlet structure must be relocated to prevent short
\Q�• of- circuiting. Either have all inlets come into one forebay, with the outlet located opposite, or
2J' �A qqQ move the outlet to create a minimum 3:1 L:W flow path from each inlet to the outlet. The
r ) current design does not utilize all of the pond, does not meet the 3:1 L:W ratio, and has the
potential for short circuit. If site geometry precludes a 3:1 ratio. provide sufficient baffling
in the pond to create a flow path to meet this requirement.
✓13. Please note on the plans that all roof drains must be collected and directed either into the
forebay, or into the collection system.
14. What type of development is planned for the offsite area? Please account for this area in the
calculations at the full buildout potential. I am also concerned that the developers of that tract
will tie in their development drainage to the catch basin in the street, (not just that small part
shown within your drainage area) and it will dump a lot more water into this pond that we are
permitting it for.
15. Please identify the site on the location map.
16. The invert of the orifice is supposed to be at the permanent pool. Please revise your
spreadsheet calculation to reflect this.
Q1�*17. Please report the storage volume provided between the permanent pool and the storage
( Q(, elevation in the calculations.

----------------------------------------------
a\ 18. Use of the 85% TSS chart REQUIRES a vegetated filter prior to discharge into waters of the
a\0 State, of which the wetland is one. Either use the 90% chart, or provide a vegetated filter per
�� the enclosed detail. The surface area is deficient for meeting 90% as currently designed.
19. Why does the application show a total impervious area of 12.15 acres, and the pond design
calculations account for only 11.87? See comment #8 on Page 1. The proposed impervious
in the first box on page 2 of the application lists 12.05 acres. Please clarify.
Please note that this request for additional information is in response to a preliminary review. The
requested information should be received by this Office prior to July 3, 1998, or the application will be
returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee.
If you have any questions concerning this matter please feel free to call me at [phone].

NARRATIVE OF STORMWATER TREATMENT AND MANAGEMENT
Introduction
The Covil Ave.Apartment Project is subject to certain watershed restrictions because the water
that leaves the site drains to surface waters that are being protected by NCDENR and the local
govemment. This project is categorized as"high density option"and is limited to 60%impervious area
with stonnwater control. A wet detention pond will function as the water quality control necessary to
meet the State requirements. The wet detention pond is intended to function as designed forever. The
operation and maintenance of the Detention Pond Facility will forever be the legally responsibility of the
Owner and or Home Owners Association associated with the site. This requirement is legally upheld
by an Operation and Maintenance Agreement between the Owner and the NCDENR. The Operation
and Maintenance Agreement should be administered by a responsible party to ensure that the
objectives are met. As the Agreement dictates; routine maintenance of the Wet Detention Pond Facility
and the associated stormwater collection system should be performed to ensure continuous water
quality goals set by NCDENR. Following is a narrative of how the treatment and management goals
will be achieved.
A. Construction
Construction of the facility will conform to the Engineer's plans and specifications. All sediment that
collects in the basin during construction will be removed after the site is stabilized.
B. Basin Access
Access to the pond and forebays will be allowed for via two entry points. The parking lots will serve
as entryways to the basin. The west forebay will be accessed through the space between
buildings 5&6. The east forebay will be accessed through the space east of building 4. The basin
will be accessed through either of the aforementioned open spaces or the open space between
buildings 4&5. A 10'access easement measured from the top of bank of the basin will be
recorded and maintenance will be performed periodically to ensure that access is provided as
intended.
C. Routine Maintenance
Refer to the"Operation and Maintenance Agreement"between the Owner and NCDENR.
Attachment of justification of requirements pertaining to Required Items Checklist of item II. of
the Wet Detention Basin Supplement Form
Item b.)The basin length to width ratio is approbmately 2.5:1 and not the suggested 3:1 ratio. We
request a variance to this requirement in order to achieve the site geometry we strive for on
the grading plan.
Item l.) A trash rack for both the orifice and riser will be specified on the constmdion drawings.
Item k.) Sediment storage is not provided for in the permanent pool as additional volume above the
required volume associated with the average depth, however access to the basin for routine
clean-outs is provided.
Item I.) A 30 ft.vegetative fitter is not provided at the outlet because the outlet flows into a wetland
where the effluent is then held and infiltrated into the ground overtime. The wetland now
captures runoff and infiltrates all of this into the ground.
Item m.) A recorded drainage easement for the basin with access to the nearest right-of-way will be
provided.
