Wrightsboro Elementary School
High Density Commercial Stormwater Project
New Hanover County
The Wilmington Regional Office received a modification for the Stormwater Management Permit Application for
Wrightsboro Elementary School on April 3, 1998, with final information on July 1, 1998. Staff review of the plans and
specifications has determined that the project, as proposed, will comply with the Stormwater Regulations set forth in Title
15A NCAC 2H.1000. We are forwarding Permit No. SW8 960823 Modification dated July 24, 1998, for the construction
of Wrightsboro Elementary School.
This permit shall be effective from the date of issuance until July 24, 2008, and shall be subject to the conditions and
limitations as specified therein. Please pay special attention to the Operation and Maintenance requirements in this permit.
Failure to establish an adequate system for operation and maintenance of the stormwater management system will resull
in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an
adjudicatory hearing upon written request within thirty (30) days following receipt of this permit. This request must be
in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
Office of Administrative Hearings, P.O. Drawer 27447, Raleigh, NC 27611-7447. Unless such demands are made this

Stormwater Project No. SW8 960823 Modification
Wrightsboro Elementary School
New Hanover County
The Wilmington Regional Office received a modification to the Stormwater Management Permit
Application for Wrightsboro Elementary School on April 3, 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 block off the overflow piping from the former infiltration pond inlet structure. For
detention, all overflows must take place after the runoff has gone through the pond. You also
have the option of raising the weir overflow by 1 foot, to the same elevation as the top of
bank, 98.0.
2. Is the drainage area to the system unchanged from the previous infiltration approval?
3. Provide pavement, sidewalk and building dimensions.
4. The permit application must be signed by the Superintendent, or a signed agent authorization
must be provided.
5. There was a mistake in the addition of the impervious surfaces on the previous submittal,
which was corrected then, but is not shown now. Please revise the application to show a total
of 66,200 square feet of impervious area; 24,400 in building, and 41,800 in parking.

Dear Mr. Shiver:

John R. Andrew, P.E.

J. Phillip Norris, P.E.
• Fax 910/343-9604
We have been asked by New Hanover County Schools to respond to your letter of
March 24, 1998 concerning the above project.
First, it was an oversight that your inspection report dated October 6, 1997 was not
responded to in writing. It was certainly not anyone's intention to ignore your concerns.
In fact, before receipt of that letter and since its receipt, we have all been working with
the contractor on the project to correct the failure of the infiltration system to function as
designed. We are enclosing copies of a few construction observation reports from July
21, 1997 to January 7, 1998 which indicate our concerns about the construction of the
infiltration area. We have been back and forth with the contractor to correct previous
problems which included over -excavation of the infiltration area into the water table,
over -filling of the area and incorrect construction of the outlet/inlet structures. As of
today, we believe that the infiltration area now represents the design as permitted.
However, as expressed in our construction observation report dated January 7, 1998,
we are concerned that in the over -excavation, over -filling and re -grading of the
infiltration area, compaction has taken place that has limited the ability of the soils to
accept the stormwater. We had attempted to monitor this over the last month, but were
hampered by the unusual rainfall events. With several weeks of dry weather, we had
hoped that the system would ,respond in a positive fashion. However, a site visit today
revealed that water was still in the infiltration area.
Mr. Rick Shiver/NC DENR
March 31, 1998
Page 2
We have discussed this situation with Eddie Anderson with New Hanover County
Schools and he agrees with us, that the best solution at this time is to re -design the
system as a wet retention pond. Our preliminary design work shows that this is
possible within the existing infiltration area footprint.
We suggest the following schedule for your review and discussion for the redesign,
permitting and construction of a wet pond system.
1. Submit package for NC DENR approval 4/3/98
'2. Allow 90 days for NC DENR review & approval;
Obtain permit 7/3/98

CONSTRUCTION OBSERVATION REPORT Project Number 96155
Project Name: WRIGHTSBORO ELEMENTARY SCHOOL
Date: Wednesday, January 7, 1998 Weather: 68 degrees, cloudy Contractor: Graka Builders
Report:
Conducted site visit with Jim Rains from Boney Architect. Met on site 4:30 p.m.
Purpose of the visit was to look at the stormwater infiltration area to determine if the contractor has
made corrections that were requested in previous reports.
During the visit, we measured the distance from the top of the grate to the top of the weir in the inlet
structure. It measured 8". The plans call that the top of the weir should be 12" from the top of the grate.
We recommend that the contractor come back and either cut a notch in the wall or either tear the wall
down so the weir height is 12" below the top of the grate.
Measured the water depth in the infiltration area itself by going into the pond wearing hip boots and
using a tape. We had readings anywhere from 12" to 18" in depth. We feel that once the weir elevation
has been revised as previously mentioned that the water depth in the infiltration area will be within
tolerances allowable for that area.
We are concerned that with the amount of construction activity that has taken place in the infiltration
area from the contractor making repairs and placing material in the infiltration area due to his previous
over excavation of that area that compaction of the subgrade may have taken place that would inhibit the
infiltration rate of the existing soils. We hope that once the weir has been repaired that this will not
prove to be the case. We will monitor the situation to see if the water does indeed draw down in a
reasonable length of time.

CONSTRUCTION OBSERVATION REPORT

Date: 11/17/97 Weather: Cool, clear
Project No. 96155
Contractor: Graka Builders
1. The purpose of the site visit was to look at the infiltration area to determine if
corrections had been made per previous reports. It is apparent contractor has
placed fill material in the infiltration area as suggested to bring it back up to the
proper grade. There was no water observed to be standing anywhere in the
infiltration area with the exception of the area near the inlet structure. I question
whether the fill material has been placed at the proper grade. It appears that it
might be higher now than the plans call for, but this can be only be substantiated
by survey information. Also noted that at the inlet structure into the inlfiltration
area, someone has broken down the baffle wall that separates the two
chambers, rendering the structure useless, and certainly not certifiable. This will
need to be repaired per project plans.

MEMORANDUM
TO: Ken Phelps
Boney Architects
RE: Wrightsboro Elementary School
Stormwater Infiltration Area
A&K Project No. 96155
Based on site visits conducted during the week of September 5, we have determined
that the infiltration area has not been constructed in accordance with the approved
plans and specifications. Items that require revision are as follows:
1. The outlet structure that directs the water from the parking lot into the infiltration
area has not been built correctly: It currently has grates on both side of the
baffle wall. Details shown on the plans indicate that there should be a grate on
the side of the box that leads directly to the pond. The other side of the box
should only have an access, which is nothing more'than a manhole ring and
cover. As the box currently exists, water can by-pass the infiltration area, which
is not allowable under the permit.
2. Secondly, based on survey information provided by the Contractor, it is apparent
that the infiltration area has been built lower than the plans call for. We are still
not certain of the exact extent of that. The survey indicates that the inlet into the
infiltration area is approximately 6-8 inches lower than what the plans indicate.
Based on my site observaticns, I would assume that it is over -excavated
anywhere from 1 to 1'/z feet. This cannot be determined without additional
survey information and spot elevations in the infiltration area itself. The
possibilities of ways to remedy this problem would be to bring in suitable fill
material back to design grade, or secondly, to install some type of French drain
system underneath or on the sides of the pond to allow water to soak through
the soils and then go out into the adjacent ditch.

Report:
Project No. 96155
Contractor: Graka Builders
1. Conducted site visit this date to look at stormwater infiltration area. Observed
that water was standing in the infiltration area. This area is designed to hold
water for less than 5 days after a rainfall event. Based on previous site visits we
have always seen water in the basin. We question whether the basin has been
over excavated and suggest that the bottom elevation be confirmed by the
contractor.
2. The side slopes on the basin are not built as shown on the plan. The plan
contours indicate a gentle side slope of 4 or 5 to 1, which is mowable and not
steep in appearance. This must be corrected. No indication of grassing was
seen. Only weeds are growing on the pond banks.

Re: NCDEHNR Notice of Recommendation for Enforcement
Wrightsboro Elementary
Dear Jim:
DR. DALE F. MARTIN
Superintendent
EDWARD J. ANDERSON
Director, Facility Planning
We have received notice from North Carolina Department of Environment and Natural
Resources that they are considering enforcement action for our failing to respond to the
inspection report dated October 6, 1997. The inspection notice cited a failing infiltration
system, and which required action to either return the system to a compliance status, or
redesign the system as a detention pond, and to provide the Engineer's Certification.
This has been an ongoing issue between the contractor and the engineer for over six (6)
months. It is my understanding that the infiltration area should not hold water for more
than five (5) days. I have never seen the area without standing water. There have been
numerous conversations concerning this issue and the contractor has made unsuccessful
attempts to correct the problem. I have heard excuses from it being a design problem to it
being a installation problem. NCDEHNR has been more than reasonable and lenient in
dealing with this matter. We are appreciative of their notice and grateful that they have
given Lis the opportunity to respond.
Please provide me and Mr. Rick Shiver, P.G., NCDEHNR Regional Supervisor, with an
explanation for this violation and a detailed plan to resolve this issue. This plan must
outline steps required to correct all violations and timelines for completing each step. I
would certainly hope that this issue could be completely resolved, including engineer's
certification and approval/acceptance letter from NCDEHNR within 30 days In
accordance with the NCDEHNR notice, our explanation and our plan for making the
necessary correction must be received by 5:00 p.m. April 9, 1998.;

within ten (10) days, the explanation and correction plan is approved by NCDEHNR and
that all corrections are completed in a timely manner. We are withholding all payments to
Boney Architects and Graka Builders until this matter has been resolved.

Re: Infiltration Pond
Wrightsboro Elementary
Dear Jim:
DR. DALE F. MARTIN
Superinfe�t
EDWARD). ANDERSON
Director, Fcciliy Plonning
We have received a compliance inspection report from DEHNR on the Wrightsboro Elementary site which
list maintenance problems with the storm water infiltration pond. The report is stating that the pond has
not drawn down completely within 5 days of the last rain and DEHNR is requesting us to perform
maintenance on the system to provide the required 5 day drawdown. They also state that the system may
be redesigned as a detention pond.
It is our understanding that the system is not constructed as designed and that the contractor is waiting for
the pond to dry up before making the corrections agreed upon with the engineer. To my knowledge the
pond has not been dry since mid summer. We may need to assist the drying process in some way to
expedite corrective actions. Please discuss this issue with the engineer and contractor and collectively
make a recommendation. We need to respond to DEHNR with our plan to make the corrections noted in
their report and with a schedule for this work.
If you have any questions, please give me a call.
Sincerely,
New Hanover County Schools
