RE: Carpenter Elementary School
Stormwater Calculations
MAPA Code: CAREL
Dear Betsy,
I am hereby submitting for your review, the final storm water calculations for this
proposed elementary school. The attached report is divided into five major sections:
1. Nitrogen loading calculations
2. Hydrograph and reservoir routing (2, 25 & 100 year storms)
3. Storm drain piping (25 and 100 year frequency design)
4. Supporting 11 x 17 exhibits
5. Storm water maintenance plan
6. Erosion control calculations
1. Nitrogen Loading
The calculations show that this site has less than 10.00 LB/Ac/Yr of nitrogen load
without any BMP treatment measures. However, due to the requirement to
reduce post Q2 peaks to pre Q2 peak conditions, some detention is required. We
have elected to install bioretention basins that will reduce the Q2 peak and will
also reduce the nitrogen load.
There are two bioretention basins proposed and they are set up for sequential
treatment of a portion of the site watersheds. The watersheds that drain through
these basins also drain through an undisturbed 100' riparian buffer. The end
result is the requirement to pay a one time fee of $11,196.90.

2. Hydrograph and Reservoir Routing
For storm water entering the bioretention basins, a triangular hydrograph was
developed whose peak and time of concentration match the calculations for the
storm drain piping. Multiple inputs resulted into combined hydrographs with the
total volume of the two input hydrographs and a new combined peak.
Storage - discharge - volume curves were established based on the
characteristics of the basins. The 2, 25, and 100 year storms were calculated to
confirm basin performance. For the two year frequency storm, the calculations
indicate,an existing peak of 30.00 cfs (hydrograph #12) has been reduced to a
peak of 11.00 cfs (Hydrograph #11) from the proposed development. The
existing hydrograph is based on a comparative watershed of the same area
undeveloped.
3. Storm Piping Design
Wake County Public Schools require all piped storm drainage to be designed for
the Q25 peak capacity. You will find in this report all HGL calculations for the 25
and 100 year frequency storms. Calculations are based on the rational formula
and the IDF curves developed by Dr. Rooney Malcolm (published in Raleigh's
storm water management manual) for the Raleigh area.
Although the proposed bioretention basins significantly reduce the Q25 peaks, the
basin storm drain pipe outlets have been sized for the full Q25 peak without
regard to detention. This is an additional safeguard, should there be any failures
of the basin systems. All pipe outlets are to be protected with rip-rap at flared
end sections to prevent erosion problems.
4. Exhibits
There are two 11 x 17 exhibits attached:
1. Storm drain watersheds
2. Impervious cover documentation
5. Storm water maintenance manual
This brief manual provides the Owner and the maintenance staff with the
required schedules and procedures for maintaining the storm drain systems

proposed. If followed, the procedures outlined in this manual will ensure that the
storm drainage system will perform as designed and will continue to provide the
nitrogen reduction and the peak flow control throughout the life of the project.
Please let me know if you have any questions concerning the information provided. I
will be happy to sit down with you and review any aspect of this storm drainage system
and the storm water management plan.

STORM WATER MANAGEMENT MANUAL
Carpenter Elementary School
Morrisville Parkway
Cary, North Carolina
The purpose of this manual is to establish a required schedule of maintenance activities
and procedures for the continued performance of the storm water management system
on this school site. The procedures and schedule described herein are required by the
Town of Cary and must be strictly adhered to. Documentation of compliance must be
maintained in writing at the school site at all times. As a minimum, the maintenance
record must include a description of the activity or procedure performed, the date
completed, and the printed name and signature of the responsible person in charge.
Description of Systems
The storm water management system on this site is comprised of a conventional
subsurface piped collection system designed for the 25 year frequency peak flow. Roof
water and all surface runoff is collected in the pipe system and then directed through
two bioretention basins on the site. In addition, the storm water is also directed through
a 100' permanent riparian buffer. This manual covers the maintenance and operation of
the pipe collection system, bioretention basins, and riparian buffer.
Schedule of Required Maintenance Activities
Frequency Activi
As required Any pipe inlets, curb inlets, or drain inlets partially
blocked by tree limbs or other debris, shall be
cleared immediately.
Any damaged or missing grates or frames shall be
repaired or replaced immediately.

' Frequency Activity
' Any concrete flared end section which becomes
damaged more than 30% shall be replaced within 60
calendar days.
' b
li
s,
m
When storm damage occurs, trim hazardous
repair stream bank, and maintain a healthy vegetative
' buffer within all riparian buffers.
Annually All storm drain inlet structures shall be inspected for
' debris or sediment in the bottom of the box. Any
sediment greater than 1/4 the outlet pipe diameter in
' depth shall be removed.
Repair or replace all rip-rap at all flared end sections
' to original dimensions on approved site plans.
Visually inspect all flow lines of storm drain piping.
' Remove any obstructions. Flush pipe clean if
sediment is greater than 1/4 of pipe diameter in depth.
' Visually inspect all piping locations for joint failures
that result in surface cave-ins or depressions.
' Once per 5 Years Through clean-outs provided on corrugated
subsurface drains with water to confirm positive flow
with no blockages. If positive flow cannot be
' confirmed, identify point of obstruction and excavate
to repair.
' Once per 20 Years Replace any dead or aging plant material in the
Bioretention basins.
' i
il
x,
m
Evaluate selected excavations of planting so
non-woven filter fabric, and sand filter for sediment or
' excessive fines contamination. If filter fabric or sand
filter appear clogged or ineffective, replace all the

' planting soil mix, filter fabric, sand filter and
lants
ciated
.
p
asso

No additional impervious area may be added to this site without revising nitrogen
calculations to the Town of Cary, and if necessary, paying appropriate fees and nitrogen
buy down fees. Areas denoted as undisturbed on the exhibits submitted to Cary
Engineering may not be cleared or graded upon without the approval of the Town of
Cary Engineering Department. Plant material inside the bioretention basins must be
pest free and maintained in healthy condition at all times.

MEMORANDUM

/88&?J6
TO: John Dorney, DWQ Wetlands Group
FROM: Kevin Martin
Cpp?
RE: Your 2/12/03 letter regarding Carpenter Elementary School
(DWQ#03-0143) Wake County (copy attached)
The purpose of this memo is to respond in part to your questions
1, 2, and 3 in your letter.
Questions 1 and 2 relate to Stormwater so the project engineer
Larry Ragland with McNeely and Associates (782-9677) will address
these. We have arranged a meeting with Todd St. John of your office for
3/11/03 to be sure these issues are addressed to your satisfaction.
As far as Item 3 goes, the plan is to drain the pond for safety
reasons (which does not require a 401) and place a pipe through the old
dam so that the pond remains drained. To avoid downstream erosion the
engineer plans to place a rip rap energy dissipater at the outlet shown on
the previously submitted plan. Currently the pond is not breached. The
attached site photos show the current site conditions downstream and
upstream of the dam. The old dam will also serve as a cross-country
running/walking trail. The emergency spillway is currently functioning
as the primary spillway since the old pipe through the dam is clogged.
The previous consultant considered this spillway jurisdictional which
would not be true if the pipe through the dam functioned properly.
WkIUNDS/401 GROUP
To summarize the piping of the "channel" proposed is actually the
emergency spillway. The rip rap disskWer ifs ?904e placed at the end of a
pipe, which is to be placed through the existing dam when the pond is
drained. See attached plans anWARWALITY SECTION
Please call if you require further information to process this 401.

Dear Mr. Wiltzius:
On February 11, 2003 the Division of Water Quality (DWQ) was notified by receipt of your application
regarding your plan to fill waters for the purpose of constructing a road crossing and stormwater facility in Wake
County. Approval from DWQ is required to disturb these wetlands. Please provide 7 copies of the following
information and refer to the DWQ # listed above in your reply. Please show these on maps of suitable scale (for
instance 1" = 100 feet) so we can begin to determine your projects' compliance with 15A NCAC 2H.0500.
1. Please provide the location of any proposed stormwater management practices as required by
GC 3362.
2. Please provide detailed plans for the stormwater management practices required by GC 3362.
Please indicate what type of stormwater management facility is proposed for the area associated
with Impact A.
3. Please provide detailed plans of the proposed trail crossing at the old pond dam. It is unclear to
us whether you are proposing to place a pipe or just fill within the stream. An explanation of
the existing conditions with photographs of the area would be helpful.
Please telephone Bob Zarzecki at 919-733-9726 if you have any questions or would require copies of our
rules or procedural materials. This project will remain on hold as incomplete in accordance with 15A NCAC 2H
.0505(c). The processing time for this application will begin when this information is received. If we do not hear
from you by writing within three (3) weeks we will assume you no longer want to pursue the project and will
consider it withdrawn.

i SECTION
The purpose of this letter is to request approval for our clients to utilize Nationwide
Permits 39 and 18 for the project known as Carpenter Elementary School. The property
(±25-acres) is 1/2 mile southeast of Carpenter, east of Hwy 55 and south of SR 3014 near
Cary, NC. The site is shown on the attached plans and USGS Topo Quad vicinity map.
On March 6, 2002, Ms. Amanda Jones approved the wetland delineation performed by
others. The owner and applicant is Wake County Public School System.
Impacts totaling 0.081 acres of vegetated wetland and 65 linear feet of Stream are
proposed (see impact maps) for the school. This includes 65 linear feet of channel impact
and 0.011 acres of wetland for construction of a trail over the breached dam of an old
pond using NW 39. Impacts performed under NW 18 are to 0.07 acres of wetland for
grading/fill slopes. The NW 18 impact occurs at the upper most portion of a wetland
"finger" and no jurisdictional wetlands or waters are upstream from the proposed impact.
Please call if you have questions or require further information. If you intend to perform
site visits please call and we will arrange for someone to accompany you. Further details
are provided on the attached PCN form.

Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
All wetlands on-site were avoided except a small (0.07 acre finger) with no iurisdictional or
waters above it An existing pond dam was used for the trail crossing. The pond is being
breached for school safety considerations
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Page 9 of 12
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetl-,tnds/stn-ngide.htmi.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Due to the small size and duality of wetland/stream impacts the client proposes to preserve
all other wetlands (0.843 acres) and buffers on-site for mitigation. Impacts fall below the
mitigation thresholds for DWQ The applicant is also providing nitrogen removal for on-site
Stormwater (calculations attached).
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
(919, 733-5208 to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrt)/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
