IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
On -site stormwater runoff in locations with new built upon area will be collected into a storm drainage
network and routed to three proposed infiltration basins These infiltration basins have been sized to treat 2.5
times the required treatement volume, thus eliminating the need for an offline bypass or vegetative filter strip.
On -site stormwater runoff in locations with no build upon area will be routed through grassed swales and
discharged offsite.
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUD Approval Date:
❑ Valid Building Permit Issued Date:
❑ Other: Date:
b.If claiming vested rights, identify the regulation(s) the project has been designed in accordance with:
❑ Coastal SW —1995 ❑ Ph II — Post Construction
3. Stormwater runoff from this project drains to the Cape Fear River basin.
4. Total Property Area: 170.81 acres 5. Total Coastal Wetlands Area: 0 acres
6. Total Surface Water Area: acres
7. Total Property Area (4) — Total Coastal Wetlands Area (5) —Total Surface Water Area (6) = Total Project Area':
170.81 acres
Total project area shall be calculated to exclude the following: the normal pool of impounded structures, the area
between the barks of streams and rivers, the area below the !Normal High Water (NHW) line or Mean High Water
(MHW) line, and coastal wetlands landward from the NHW (or MHW) line. The resultant project area i`.s used to
calculate overall percent built upon area (BUA). Non -coastal wetlands landward of the NHW (or MHW) line may be
included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 6 %
9. How many drainage areas does the project have?1 (For high density, count I for each proposed engineered
stor►rrzoater BMP. For low density and other projects, use I for the whole property area)
10. Complete the following information for each drainage area identified in Project Information item 9. I€ there
are more than four drainage areas in the project, attach an additional sheet with the information for each area
provided in the same format as below.

Infiltration Basin Operation 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.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
.six weeks).
No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Infiltration Basin Operation 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.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every stofm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location

Subject: Stormwater Permit No. SW6120703
Highland Middle School
Overall Low Density Residential Subdivision with Infiltration Basins
Harnett County
Dear Mr. Birath:
The Stormwater Permitting Unit received a -complete Stormwater Management Permit Application for
Highland Middle School on August 18, 2012 after requesting additional information on July 25, 2012. 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 and Session Law 2006-246. We are
forwarding Permit No. SW6120703, dated August 20, 2012, for the construction, operation and
maintenance of the subject project and the stormwater BMPs.
This permit shall be effective from the date of issuance until August 19, 2020 and shall be subject to the
conditions and limitations as specified therein, and does not supersede any other agency permit that may
be required. Please pay special attention to the conditions listed in this permit regarding the Operation and
Maintenance of the BMP(s), recordation of deed restrictions, procedures for changes of ownership,
transferring the permit, and renewing the permit. Failure to establish an adequate system for operation and
maintenance of the stormwater management system, to record deed restrictions, to follow the procedures
for transfer of the permit, or to renew the permit, will result 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 permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please contact Brian
Lowther at [phone], or [e-mail].
Sincerely,

No homeowner/lot owner/developer shall fill in, alter, or pipe any drainage feature
(such as swales) shown on the approved plans as part of the stormwater
management system without submitting a revision to the permit and receiving
approval from the Division. .
2. The permittee is responsible for verifying that the proposed built -upon area for
the entire lot does not exceed the maximum allowed by this permit. Once the lot
transfer is complete, the built -upon area may not be revised without approval
from the Division of Water Quality, and responsibility for meeting the built -upon
area limit is transferred to the individual property owner.
3. If an Architectural Review Board or Committee is required to review plans for
compliance with the BUA limit, the plans reviewed must include all proposed
built -upon area. Any approvals given by the Board do not relieve the homeowner
of the responsibility to maintain compliance with the permitted BUA limit.
4. The Director may notify the permittee when the permitted site does not meet one
or more of the minimum requirements of the permit. Within the time frame
specified in the notice, the permittee shall submit a written time schedule to the
Director for modifying the site to meet minimum requirements. The permittee

Attn: Mr. Brian Lowther
Re: Highland Middle School
Dear Mr. Lowther,
Thank you for your review of the referenced project. Please accept our revisions from comments issued on
July 25'h, 2012. Comments to the items in question are as follows:
I. While the project built upon area is less than 24%, vegetated conveyances must be used to the
maximum extent practicable. In areas where the stormwater does not flow to a BMP (85% TSS
removal), vegetative conveyances or sheet flow must be used. The only piping allowed in these
areas is for under a road or at a curb outlet to a curb outlet swale.
Timmons Response: Storm piping has been removed, except for road culverts, in areas not
draining to a BMP. This was primarily shown previously around the athletic fields. Swales have
now been proposed to route runoff to areas where it can be infiltrated back into the ground.
2. Please include the I11. Required Items Checklist for each Supplement form. It can be found as one
of the tabs in the excel tile.
Timmons Response: The I11. Required Items Checklists have been provided for each
Supplement form.
3. Please provide a Low Density Supplement form.
Timmons Response: Low Density Supplement form has been provided.
4. Please provide Swale details on the plans.
Timmons Response: A typical Swale detail has been provided on sheet G408. A table has been
provided to illustrate the dimensions for each swale. Drainage areas have been included for
reference.
5. Please include a plan sheet ofthe overall project area and make sure to include any wetlands or
surface waters. If no wetlands are on the site, please include a note saying none exist on site
and/or adjacent property.

I
Timmons Response: A note has been added on the overall plan sheet C-001 indicating that no
wetlands or surface waters exist onsite. This information has also been added to the general
notes on the Cover Sheet
6. The plans show curb around the parking lots but there are no curb cuts or drop inlets. Please
provide more information on how stormwatcr will get to the infiltration basins.
Timmons Response: Concrete flumes have been added to allow runoff from the parking lot into
Infiltration Basin 2. Runoff for Infiltration Basins 1 and 3 will enter through storm drainage
pipes as previously shown.
7. Please show proposed drainage easements and public right of way on the plans.
Timmons Response: Proposed drainage easements have now been shown and labeled around
swales and infiltration basins on sheets C400-402. A proposed right of way has also been shown
and labeled.
We hope this will satisfy any of your concerns far this and will lead to the issuance ol' your approval. If I
can be of further assistance, or if you have additional concerns, please don't hesitate to give me a call at
919-866-4938.
