Wet Detention Basin Inspection and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
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 ® does not incorporate pretreatment other than a forebay.
Important 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 detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance,the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established,it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of inspection and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

RE: C. A. D. A. Lot near Aboskie,NC,Hertford Co. EW08.019
Seasonal High Water Table Depths.
Dear Mr. Valnell:
Thank you for contacting Environmental Services, Inc., (ESI) concerning the above
referenced project. As requested, ESI investigated the soils to find the depth to soil
indicators for the seasonal high water table (SHWT), within the approximately three acre
lot on Modlin Hatchery Road.
Seasonal High Water Table Depths
SHWT depths ranged from 19" near the drainage ditch toward the southwest, to 37" near
the center of the lot. The depths to soil SHWT indicators in each boring were as follows:
Borin 0 SHWT Depth Notes
1 2011
2 29"
3 3711
4 191,
5 31"
6 24" Sand lined pores 9.5", color OK.
7 26" Sand lined pores from 18—24".
8 2911
9 2611 Perched WT from 11 — 18"
10 2711
11 35"
12 27"
See figure 1 for the soil boring locations.
SHWT indicators are shallowest near the drainage ditch to the southwest, but are found
considerably deeper within a short distance fiirther away from the ditch. Aside from the
FLORIDA • GEORGIA • NORTH CAROLINA • SOUTH CAROLINA

2
shallowest SHWT indicators being close to the drainage ditch, no other trend in SHWT
depths was seen.
Borings 6, 7 and 9 had some indications that the soil can sometimes perch water above
the subsoil horizons and/or a plow pan. Borings 6 and 7 only had a few sand lined pores,
but boring 9 had redoximorphic features indicating occasionally saturated conditions.
Environmental Services, Inc., appreciates the opportunity to offer you our services. If
you have any questions or comments, or need any additional information, please feel free
to contact me at(252-402-7354)or at our office number(252-946-6660).

Dear Ms. Surface:
This office received a Coastal Stormwater permit application and plans for the subject project on
October 15, 2008. A preliminary review of your project indicates that before a State Stormwater permit
can be issued the following additional information is needed:
The NC Department of the Secretary of State search did not show any records of Ms Sallie
Surface being an registered agent for this corporation. If an agent signs the application, then
a letter of authorization is needed from the president or vice president of the Corporation
authorizing the agent to sign the application, or the stormwater application can be signed by
the president or vice-president.
2. Provide the stream classification and index number in Section 111.8 of the stormwater
application.
/3. Delineate wetlands on site or provide a note on plans that none exist.
J 4. This permit application was received on October 15, 2008. As per new Stormwater rules
(Effective October 1, 2008), required design rainfall depth for non-SA waters is 1.5". Please
revise your calculations, plans and all other documents that will be affected by this change
(plan details, storage elevations, drawdown calculations etc..)
5. Provide 2 sets of signed and sealed plan sheets.
The above requested information must be received in this office prior to January 3, 2009 or
your application will be returned as incomplete. The return of this project will necessitate resubmittal of

6. VSection 111.6 is filled in-cannot be left blank. One column must be filled in for each
proposed wet pond.
2 7. If the applicant is a corporation, partnership or LLC, look it up on the Secretary of State
Corporations Database. Make sure corporation is spelled correctly (capitalization and
punctuation matter) and that the person signing"the application is at least a vice-
president in the corporation, a General Partner in the partnership, a member in a
member-managed LLC, or the manager of a manager-managed LLC. Need
documentation to support if the Articles of Incorporation do not list the members or
q� managers of the LLC. If an agent signs,then a letter of authorization is needed from the
president, vice president, general partner, member or manager.

B. CALCULATIONS
e- - r 1. The orifice is sized based on drawing down the calculated minimum volume in 2-5
days. The average head to use in the orifice equation is approximately one-third of
the distance between the permanent pool elevation (PPE) and the elevation of the
t / next available outlet above the permanent pool. The elevation of the next available
outlet must be either the elevation where the minimum volume is provided, or it can
be higher. The temporary pool elevation (TPE) to report on the supplement will be
the elevation of the next available outlet above the PPE. The temporary pool volume
(TPV)to report on the supplement is the volume between the specified PPE and the
TPE.
2.*or Phase II projects that are within % mile of and draining to SR waters, the
difference in runoff from the predevelopment and post-development conditions for
the 1 year 24 hour storm must be controlled and treated.
3. For Phase II projects, the discharge rate leaving the pond can be no more than the
pre-development discharge rate for the 1 year 24 hour storm.
4or Phase II projects draining to SA water, no discharge to surface waters may occur
f m wet ponds.The discharge leaving the orifice must be effectively infiltrated prior to
eaching surface waters.
5. The average pond depth is the permanent pool volume divided by the permanent pool
surface area. The result must be between 3 ft. and 7.5 ft. Parts of the pond can be
deeper than 7.5 ft., but in no case can any part of the pond be less than 3 ft deep.
QVI IfAhe 85%TSS chart is used a 30'vegetated filter must be provided at the outlet of the
ond. If the 90% TSS chart is used no filter is rPni irad.
7. llse the correc A/DA TSS chart rom t e BMP Manual noting that there are different
V/ arts for different areas of the State.
8. equired surface area at permanent pool.
9. Provided surface area at permanent pool (Based on pond dimensions)
1 Required volume calculation based on 1.5"storm for Phase II projects*and 1"storm for
all others projects. *unless the project is Phase II and within ''/2 mile of and draining to
waters then the volume calculation must be based on difference between the pre
Wand post development conditions for the 1-yr 24-hr storm.
,Table of elevations, areas, incremental volumes and accumulated volumes for overall
Vpond and for forebay, to verify volumes provided.
12. Forebay designed to hold 20% of the permanent pool volume. (Range of 18%-22%
,,rr K.)
13N on-erosive flow for 10 yr. storm in the vegetated filter, if using 85% TSS.
'L 14. The seasonal high water table must be at or below the proposed permanent pool
el vation to assure that the necessary volume will be available above the permanent
ool.
15 Rounding numbers off during the calculation process can result in deficiencies. Do not
,Z round the numbers until you get to the final result.
16' An additional one foot must be excavated below the bottom elevation of the pond.The 1
foot sediment accumulation depth is not included in the average depth calculation.

C. PLANS- Due to storage space constraints, plan sheets should be kept to a minimum. For
small commercial single wet pond projects, the plan set could consist of only 2 or 3 sheets,
layout,,grading and details. For larger projects, show as much information as possible on as
few Oets as possible, without cluttering them up.

the 85% TSS chart was used, a 30 ft. vegetated filter strip is required to be
shown on the plans & detailed (elevations, inverts, slopes, and flow spreader
echanism). Please note that the filter strip is not a ditch.
24 orebay is provided for each inlet and located so as to prevent short-circuiting.
25. he pond must have a minimum 1.5:1 length to width ratio and a minimum 3:1 flow path
length. Artificial "baffles" of timber, vinyl, or earth can be used to create a longer flow
ath. The top elevation of the baffle should be set at the temporary pool elevation or
Nigher.
26. A Vegetation plan is specified for the pond, including slopes. Wetlands species are
§ted for planting on the 10:1 shelf.Weeping Love Grass is not suitable as a permanent
vegetated cover for pond slopes.
2 All roof drainage must be directed to the pond. Show the roof drain collection lines on
the plan. This is necessary for projects where the buildings back up the property lines
where roof drainage may leave the site prior to going through the pond.
