Detention Pond Maintenance Agreement
WASHINIGTON OFFICF
I.Operation and maintenance of the detention pond shall be the responsibility of the owner. OCT 1 5 1996
2.Operation of the system is automatic upon the occurrence of a rainfall event, however, there are several II�� E. M.
maintenance items that must be attended to. First of all, there must be a lawn maintenance program where the grJ
around the pond will be kept mowed during the growing season of the year. It is recommended for aesthetic reasons
that the grass be mowed on at least a bi-weekly basis unless actual growing conditions indicate otherwise, in which
case the mowing frequency should be modified to suit site conditions.
3. The outlet structure must be inspected periodically for obstructions and trash build-up. This inspection should be
done approximately once every three months to include inspection of the orifice in the drawdown device to check for
algae or other trash plugging the orifice, inspection of the rip -rap filter around the riser section for trash, cut weeds or
grasses which may tend to plug the filter, inspection of the trash rack for the same type of obstructions as with the
rip -rap filter and an inspection of the barrel section for any obstructions such as limbs or anything else that may have
passed the trash rack and pose a plugging problem. Any obstructions found shall be removed and hauled away from
the pond.
4. The forebay area must be checked for sediment deposits, especially during the first year of operation. The
frequency of the forebay inspections should be monthly until all disturbed areas have been stabilized or for a
minimum of 6 months, whichever is longer. 'fherealter, inspect forebay area every three months- To perform this
inspection elevations should be taken along the perimeter of the rip -tap flow distributionNelocity dissipation pad.
The bottom should approximately 2' to 2-1/2' below the permanent pool elevation. If this is not the case the rip -rap
pad will need to be removed, the sediments excavated to the levels indicated in die details and the xip-rap pads
replaced.
s. It should be noted that in addition to the inspection frequencies recommended above, the pond and its
appurtenances should be inspected after any major storm event that may transport large amounts of debris to the
pond.
By our signature below, we, as owner/operatorhnanager/administrator of the proposed facility do hereby agree to
perform the above mentioned items and maintain the proposed facility in proper operating condition.

Calculation of Tp (Time to Peak)
From SCS NEH 4 , page 15-7 Eqn. 15.4
Lag Time (L) _ (I 0.8*(S+l) 0.7)/(1900*Y^0.5) for L in Hrs
where: I = hydraulic length of watershed (ft)
S = (1000/CN)-10
CN = approximately same CN from TR-55
Y = avg. watershed land slope in
S = (1000/CN)-10 = 1.49425

Dear Mr. Ellis.
Ptnre (ECG 29 i4
Fin' (8') i/ I.T"'...
As per your request. I have reviewed rainfall data for New Bem and made an approximation
I
or the possible rise in groundwater due to variation in precipitation.
Based on rainfall amounts equal to 2(3 of the annual 50 inch rainfall occurring in 90 days, I
calculate a rise in groundwater of 4.26 feet Thus, the groundwater, which was measured
at 11.0 ft., would rise to 7 ft below grade. In reality, I don't believe that this would occur
because the site appeared to have good drainage to a drainage ditch to the west along US
Hwy. 70.
I hone this calculation is of assistance to you
Very truly your,

PURPOSE:
This report has been prepared for AutoZone, Inc., for the purpose of determining the
extent of existing versus proposed storm water runoff according to common engineering
practices.
DESCRIPTION:
The existing 1.47acre site is located in New Bern, NC. Currently the site is undeveloped.
The existing site can be divided into four (4) drainage areas as shown on the attached
existing conditions drainage area plan.
The proposed retail development can also be divided into five (5) areas as shown on the
attached proposed conditions drainage area plan.
ASSUMPTIONS USED:
Existing Conditions:
l) All flow calculations were computed using the rational method.
Coefficients used were based on common engineering practice.
The rainfall data was averaged between two cities in the area. The
rainfall curves for the 2, 5, 10, 25, 50, and 100 yr. storms is
attached.
2) Combined C factors for each area based on:
C= 0.45 - Pervious Areas
C= 0.95 - Impervious Areas
3) All areas are divided per survey information provided
by Lanier Surveying Co., Inc., survey dated March 7, 1996.
Proposed Conditions:
1) All flow calculations were computed using the rational method.
Coefficients used were based on common engineering practice.
The rainfall data was averaged between two cities in the area. The
rainfall curves for the 2, 5, 10, 25, 50, and 100 yr. storms is
attached.
2) Combined C factors for each area based on:
C= 0.45 - Pervious Areas
C= 0.95 - Impervious Areas
3) All areas are divided per attached grading plan provided by
Auto Zone, Inc., Design and Construction, dated 04/22/96.
