Dear Mr. Dorney:
We received your letter dated October 18, 1999 regarding 401 approval of the Greensboro Day
School Stormwater Management Pond and associated stream encroachments. In response to
Additional Condition 1(Deed Notification), we propose to add the necessary notification at the time
that the stormwater management pond and associated easements are platted. Therefore, the required
notification would not be completed within the 30 days requested in the approval letter.
We hope that this request will suffice to amend the time frame for platting the deed restriction.
Should you have any questions or need additional information, I can be reached at [phone].
Sincerely,

as i recall we are not requiring this pond. rather the applicant wants to
build the pond (or the city wants them to since they will have larger
parking lot). in any event the trigger for the pond is not the 401
program. therefore why should we care how big the pond is?

Background (we had a meeting with these folks a while ago): existing
School with a population from elementary to high school wants to
construct a stormwater pond. The only impact will be from the
construction of the pond. There will be some expansion, but none will
impact waters or wetlands. The surface area of the proposed pond is
about 90% of the required surface area (including accounting for offsite
drainage). The pond design is non-typical in that it has an oversized
forebay, a submerged, vegetative shelf protruding into the center of the
pond, and 2:1 sideslopes which will be stabilized with erosion control
matting. The school has yet to determine how it will limit access to the
pond by students etc (this is not one of our review requirements.) To
make up for the shortage of surface area the applicant proposes to send
stormwater into a forested buffer. However, the pictures sent by the
engineer do not seem to indicate that sheet flow will occur since the
area appears to have swales or ditches that will convey the stormwater
directly to the creek. The applicant has proposed levels spreaders;
however, these level spreaders are undersized by DWQ standards and will
discharge the stormwater to the above swales or ditches. Normally, we
would not approve such a stormwater plan w/o revisions, but considering
the fact that most of the school exists, they will be treating off-site
stormwater, part of the school has elementary aged students, the pond's
surface area would be 90% of the required for onsite and offsite
drainage, and the impacts that are triggering the 401 are only from the
construction of the pond, I was wondering if we should require further
revisions or "let this one go"...

Dear Mr. St. John:
71999
Thank you for your review of the additional materials submitted to support the original Greensboro
Day School Campus Improvements plans. In response to your comments received via email on
October 4, 1999, we submit the following:
Please see Sheet 5 for delineation of areas draining to the buffer. The included
photographs adequately show the heavily, vegetated buffer. The pictures labeled as
Swale #1 and Swale 42 correspond to the areas to be enhanced by Level Spreaders
#1 and #2. We believe these level spreaders will be adequate to dissipate the
concentrated flow coming to the swales; therefore allowing overland flow from
greater than 18 acres through the natural, heavily wooded buffer. As such, we believe
flow through the buffer in conjunction with the proposed pond offers adequate water
quality protection. Please see additional discussion on this matter in Supplemental
Calculations #2.
2. Forebay - Please see Supplemental Calculations 92.
3. Emergency Drain - Please see Sheet 11, Note 7 and the Operation and Maintenance
Agreement.

Subject: Greensboro Independent School Corp.
DWQ Project No. 990645
Guilford County
This Office received additional plans regarding stormwater management for the subject project. During the
meeting among you, me, Mr. John Domey of this Office, Mr. Ray Waugh, and Mr. Len Rindner, we had
discussed the need for certain additional information in order to properly assess storm water management
requirements. This information is as follows:
Drainage to Buffers
You were to delineate the existing on site drainage. You were to determine the condition of the
buffer at these drainage points and document this with photos. As such, please delineate the drainage
area including offsite drainage to the buffers on the site plan and provide photos of the buffer though
which the stormwatei will drain. Also, please provide any discussion necessary to explain your
conclusions. Of particular interest is whether or not drainage channels already exist in the buffer that
will tend to concentrate the flow. Also, the current level spreader device may not be adequately
address Water Quality requirements. Please refer to the 1995 or 1999 DENR Stormwater Best
Management Practices Manual design requirements for filter strips. Please feel free to call me at the
number below to discuss this matter.
In addition to the above information, the following information must be provided in order for this Office to
complete its review:
1. Forebay
All stormwater wet detention basins are required to have a forebay to facilitate TSS removal. The
total forebay volume should be approximately 20% of the total basin volume. If more than one
forebay is used, the size of each forebay should be proportional to the flow. Please revise the
engineering plans to meet this requirement.
Emergency Drain
An emergency drain must be provided to draw down the permanent pool volume.
3. Vegetated Side Slopes
4401 Reedy Creek Road, Raleigh, NC 27607 Telephone [phone] FAX [phone]
An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post-consumer paper
Normally, the basin side slopes above the permanent pool down to the vegetative shelf must be
stabilized with vegetation and side slopes no steeper than 3:1 (horizontal to vertical). However, in
this case, it will be acceptable to provide additional measures such as erosion control matting to
provide stability. This information must be specified on the engineering plans. (It is also
recommended that public safety measures be taken because the side slopes indicated are steeper than
3:1.)
4. Sediment Removal
Since the basin is proposed to be used as a sediment basin during construction, the plans must clearly
indicate that accumulated sediment will be removed prior to implementation as a wet detention
basin.
Operation and Maintenance Agreement
An operation and maintenance agreement is required for the pond as well as any other stromwater
treatment methods,that will be used. Typical requirements for an operation and maintenance plan
include the following:
• Vegetation management/mowing schedule
• Semi-annual inspections
• Debris check after every storm event
• Benchmark for sediment removal (specific elevations listed)
• Designation of a responsible party
The operation and maintenance agreement must also be signed by the responsible party and
notarized.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of
receipt of the requested information. If you have any questions or would like to discuss this project, please
contact me at [phone].

DWQ Project No. 990645
Guilford County
Dear Ms. Small:
This Office received additional plans regarding stormwater management for the subject project. During the
meeting among you, me, Mr. John Dorney of this Office, Mr. Ray Waugh, and Mr. Len Rindner, we had
discussed the need for certain additional information in order to properly assess storm water management
requirements. This information is as follows:
1. Drainage to Buffers
You were to delineate the existing on site drainage. You were to determine the condition of the
buffer at these drainage points and document this with photos. As such, please delineate the drainage
area including offsite drainage to the buffers on the site plan and provide photos of the buffer though
which the stormwater will drain. Also, please provide any discussion necessary to explain your
conclusions. Of particular interest is whether or not drainage channels already exist in the buffer that
will tend to concentrate the flow. Also, tine current level spreader device may, not be adequately
address Water Quality requirements. Please refer to the 1995 or 1999 DENR Stormwater Best
Management Practices Manual design requirements for filter strips. Please feel free to call me at the
number below to discuss this matter.
In addition to the above information, the following information must be provided in order-for this Office to
complete its review:
1. Forebay
All stormwater wet detention basins are required to have a forebay to facilitate TSS removal. The
total forebay volume should be approximately 20% of the total basin volume. If more than one
forebayis used, the size of each forebay should be proportional to the flow. Please revise the°
engineering plans to meet this requirement.
2. Emergency Drain
An emergency drain must be provided to draw down the permanent pool volume.
3. Vegetated Side Slopes
4401 Reedy- Creek Road, Raleigh, NC 27607 Telephone [phone] FAX [phone] -
An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post-consumer-paper --
Normally, the basin side slopes above the permanent pool down to the vegetative shelf must be
stabilized with vegetation and side slopes no steeper than 3:1 (horizontal to vertical). However, in
this case, it will;be acceptable to provide additional measures such as erosion control matting to
provide stability.. This information must be specified on the engineering plans. (It is also
recommended that public safety measures be taken because the side slopes indicated are steeper than
3:1.)
4. Sediment Removal
Since the basin is proposed to be used as a sediment basin during construction, the plans must clearly
indicate that accumulated sediment will be removed prior to implementation as a wet detention
basin.
5. Operation and Maintenance Agreement
An operation and maintenance agreement is required for the pond as well as any other stromwater
treatment methods that will be used. Typical requirements for an operation and maintenance plan
include the following:
• Vegetation management/mowing schedule
• Semi-annual inspections
• Debris check after every storm event
• Benchmark for sediment removal (specific elevations listed)
• Designation of a responsible party
The operation and maintenance agreement must also be signed by the responsible party and
notarized.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of
receipt of the requested information. If you have any questions or would like to discuss this project, please
contact me at [phone].

Re: Greensboro Day School

LDESI Project No. 79005
Dear Mr. St. John:
Thank you for allowing us to meet with you to discuss the possible alternatives to increasing the size
of the proposed stormwater management pond at the Greensboro Day School. As we discussed at
our meeting on August 23" d, we have decided to pursue the value of the existing heavily wooded
buffer as a means of reducing sediment flow to the pond. Included with this letter you will find a
revised plan designating this area as a permanent buffer.
The pond has been sized for an on-site impervious area of 15.06 acres. The current design plans
account for only 12.4 impervious acres. The additional 2.7 acres will be constructed over the next
decade through the completion of the master plan. Most of this additional impervious area will be
constructed on current unimproved areas that will drain directly to the buffer. Therefore, the
importance of the permanent buffer as a means of removing sediment from site drainage will only
increase as construction of the master plan proceeds.
The included plan shows the addition of two level spreaders to disperse the current areas of
concentrated flow. Future construction in this area will employ the use of additional level spreaders
as necessary to enhance sheet flow into the buffer. Construction through Phase H will direct 2.0
impervious acres to the buffer from the east. After completion of the master plan approximately 4.0
impervious acres will flow through the buffer in unconcentrated flow.

We hope that this additional information is sufficient to approve the proposed stormwater
management pond. Should you have any questions or need additional information, I can be reached
at [phone].

Constructio docume g bmitted to the Division of Water Quality for review based on
proposed str ropoe to construct the Storm Water Management Pond within the
floodway of an unnamed tributary of Richland Creek. In the process, 1001f of stream would be filled
and 3101f of stream would be excavated in order to create a 0.7 acre pond. In order to reduce the current
downstream impacts while creating a viable water quality pond within the site constraints, we believe it
is necessary to construct the pond on-line. The pond will be situated on the only undeveloped, low spot
on the property. The pond has been designed to its maximum area based upon the following constraints:
• Location of property lines (several adjoining property owners)
• Existing 8" sanitary sewer and 20' sanitary sewer easement
• Existing athletic track and fields
• Sensitivity to avoid impact of heavily wooded upstream section of waterway.
In addition to physical hardships, there is an additional safety hazard due to placing the pond on the
school property. Therefore, the pond has been designed with 5:1 side slopes closest to the soccer field
and track and a wetland area before the permanent pool depth of five feet is achieved. This gentle slope
will allow access for maintenance and monitoring, while reducing the chance that a student or athlete
could fall into the pond.
Enclosed please find a copy of the existing conditions plan (showing the existing sanitary sewer location)
and a copy of the pertinent engineering calculations. Should you have any questions or need additional
information, I can be reached at [phone].

REACH ROUTING - THE MODIFIED ATT-KIN ROUTING PROCEDURE REPLACES THE CONVEX METHOD. INPUT DATA PREPARED FOR
PREVIOUS PROGRAM VERSIONS USING CONVEX ROUTING COEFFICIENTS WILL NOT RUN ON THIS VERSION.
THE PREFERRED TYPE OF DATA ENTRY IS CROSS SECTION DATA REPRESENTATIVE OF A REACH. IT IS RECOMMENDED THAT
THE OPTIONAL CROSS SECTION DISCHARGE-AREA PLOTS BE OBTAINED WHENEVER NEW CROSS SECTION DATA IS ENTERED.
THE PLOTS SHOULD BE CHECKED FOR REASONABLENESS AND ADEQUACY OF INPUT DATA FOR THE COMPUTATION OF "M"
VALUES USED IN THE ROUTING PROCEDURE.
GUIDELINES FOR DETERMINING OR ANALYZING REACH LENGTHS AND COEFFICIENTS (X,M) ARE AVAILABLE IN THE USERS
MANUAL. SUMMARY TABLE 2 DISPLAYS REACH ROUTING RESULTS AND ROUTING PARAMETERS FOR COMPARISON AND CHECKING.
HYDROGRAPH GENERATION - THE PROCEDURE TO CALCULATE THE INTERNAL TIME INCREMENT AND PEAK TIME OF THE UNIT
HYDROGRAPH HAVE BEEN IMPROVED. PEAK DISCHARGES AND TIMES MAY DIFFER FROM THE PREVIOUS VERSION. OUTPUT
HYDROGRAPHS ARE STILL INTERPOLATED, PRINTED, AND ROUTED AT THE USER SELECTED MAIN TIME INCREMENT.
INTERMEDIATE PEAKS - METHOD ADDED TO PROVIDE DISCHARGES AT INTERMEDIATE POINTS WITHIN REACHES WITHOUT ROUTING.
OTHER - THIS VERSION CONTAINS SOME ADDITIONS TO THE INPUT AND NUMEROUS MODIFICATIONS TO THE OUTPUT. USER
OPTIONS HAVE BEEN MODIFIED AND AUGMENTED ON THE JOB RECORD, RAINTABLES ADDED, ERROR AND WARNING MESSAGES
EXPANDED, AND THE SUMMARY TABLES COMPLETELY REVISED. THE HOLDOUT OPTION IS NOT OPERATIONAL AT THIS TIME.

COMPUTER PROGRAM FOR PROJECT FORMULATION - HYDROLOGY USER NOTES
THE USERS MANUAL FOR THIS PROGRAM IS THE MAY 1982 DRAFT OF TR-20. CHANGES FROM THE 2/14/74 VERSION INCLUDE:
REACH ROUTING - THE MODIFIED ATT-KIN ROUTING PROCEDURE REPLACES THE CONVEX METHOD. INPUT DATA PREPARED FOR
PREVIOUS PROGRAM VERSIONS USING CONVEX ROUTING COEFFICIENTS WILL NOT RUN ON THIS VERSION.
THE PREFERRED TYPE OF DATA ENTRY IS CROSS SECTION DATA REPRESENTATIVE OF A REACH. IT IS RECOMMENDED THAT
THE OPTIONAL CROSS SECTION DISCHARGE-AREA PLOTS BE OBTAINED WHENEVER NEW CROSS SECTION DATA IS ENTERED.
THE PLOTS SHOULD BE CHECKED FOR REASONABLENESS AND ADEQUACY OF INPUT DATA FOR THE COMPUTATION OF "M"
VALUES USED IN THE ROUTING PROCEDURE.
GUIDELINES FOR DETERMINING OR ANALYZING REACH LENGTHS AND COEFFICIENTS (X,M) ARE AVAILABLE IN THE USERS
MANUAL. SUMMARY TABLE 2 DISPLAYS REACH ROUTING RESULTS AND ROUTING PARAMETERS FOR COMPARISON AND CHECKING.
HYDROGRAPH GENERATION - THE PROCEDURE TO CALCULATE THE INTERNAL TIME INCREMENT AND PEAK TIME OF THE UNIT
HYDROGRAPH HAVE BEEN IMPROVED. PEAK DISCHARGES AND TIMES MAY DIFFER FROM THE PREVIOUS VERSION. OUTPUT
HYDROGRAPHS ARE STILL INTERPOLATED, PRINTED, AND ROUTED AT THE USER SELECTED MAIN TIME INCREMENT.
INTERMEDIATE PEAKS - METHOD ADDED TO PROVIDE DISCHARGES AT INTERMEDIATE POINTS WITHIN REACHES WITHOUT ROUTING.
OTHER - THIS VERSION CONTAINS SOME ADDITIONS TO THE INPUT AND NUMEROUS MODIFICATIONS TO THE OUTPUT. USER
OPTIONS HAVE BEEN MODIFIED AND AUGMENTED ON THE JOB RECORD, RAINTABLES ADDED, ERROR AND WARNING MESSAGES
EXPANDED, AND THE SUMMARY TABLES COMPLETELY REVISED. THE HOLDOUT OPTION IS NOT OPERATIONAL AT THIS TIME.
PROGRAM QUESTIONS OR PROBLEMS SHOULD BE DIRECTED TO HYDRAULIC ENGINEERS AT THE SCS NATIONAL TECHNICAL CENTERS:
CHESTER, PA (NORTHEAST) -- 215-499-3933, FORT WORTH, TX (SOUTH) -- 334-5242 (FTS)
LINCOLN, NB (MIDWEST) -- 541-5318 (FTS), PORTLAND, OR (WEST) -- 423-4099 (FTS)
OR HYDROLOGY UNIT, ENGINEERING DIVISION, LANHAM, MD -- 436-7383 (FTS).
PROGRAM CHANGES SINCE MAY 1982:
12/17/82 - CORRECT PEAK RATE FACTOR FOR USER ENTERED DIMHYD
CORRECT REACH ROUTING PEAK TRAVEL TIME PRINTED WITH FULLPRINT OPTION
5/02/83 - CORRECT COMPUTATIONS FOR ---
1. DIVISION OF BASEFLOW IN DIVERT OPERATION
2. HYDROGRAPH VOLUME SPLIT BETWEEN BASEFLOW AND ABOVE BASEFLOW
3. CROSS SECTION DATA PLOTTING POSITION
4. INTERMEDIATE PEAK WHEN "FROM" AREA IS LARGER THAN "THRU" AREA
5. STORAGE ROUTED REACH TRAVEL TIME FOR MULTIPEAK HYDROGRAPH
6. ORDERING "FLOW-FRED" FILE FROM SUMMARY TABLE #3 DATA
7. BASEFLOW ENTERED WITH READHYD
8. LOW FLOW SPLIT DURING DIVERT PROCEDURE #2 WHEN SECTION RATINGS START AT DIFFERENT ELEVATIONS
ENHANCEMENTS ---
1. REPLACE USER MANUAL ERROR CODES (PAGE 4-9 TO 4-11) WITH MESSAGES
2. LABEL OUTPUT HYDROGRAPH FILES WITH CROSS SECTION/STRUCTURE, ALTERNATE AND STORM NO'S
09/01/83 - CORRECT INPUT AND OUTPUT ERRORS FOR INTERMEDIATE PEAKS
CORRECT COMBINATION OF RATING TABLES FOR DIVERT
CHECK REACH ROUTING PARAMETERS FOR ACCEPTABLE LIMITS
ELIMINATE MINIMUM REACH TRAVEL TIME WHEN ATT-KIN COEFFICIENT EQUALS ONE

COMPUTER PROGRAM FOR PROJECT FORMULATION - HYDROLOGY USER NOTES
THE USERS MANUAL FOR THIS PROGRAM IS THE MAY 1982 DRAFT OF TR-20. CHANGES FROM THE 2/14/74 VERSION INCLUDE:
REACH ROUTING - THE MODIFIED ATT-KIN ROUTING PROCEDURE REPLACES THE CONVEX METHOD. INPUT DATA PREPARED FOR
PREVIOUS PROGRAM VERSIONS USING CONVEX ROUTING COEFFICIENTS WILL NOT RUN ON THIS VERSION.
THE PREFERRED TYPE OF DATA ENTRY IS CROSS SECTION DATA REPRESENTATIVE OF A REACH. IT IS RECOMMENDED THAT
THE OPTIONAL CROSS SECTION DISCHARGE-AREA PLOTS BE OBTAINED WHENEVER NEW CROSS SECTION DATA IS ENTERED.
THE PLOTS SHOULD BE CHECKED FOR REASONABLENESS AND ADEQUACY OF INPUT DATA FOR THE COMPUTATION OF "M"
VALUES USED IN THE ROUTING PROCEDURE.
GUIDELINES FOR DETERMINING OR ANALYZING REACH LENGTHS AND COEFFICIENTS (X,M) ARE AVAILABLE IN THE USERS
MANUAL. SUMMARY TABLE 2 DISPLAYS REACH ROUTING RESULTS AND ROUTING PARAMETERS FOR COMPARISON AND CHECKING.
HYDROGRAPH GENERATION - THE PROCEDURE TO CALCULATE THE INTERNAL TIME INCREMENT AND PEAK TIME OF THE UNIT
HYDROGRAPH HAVE BEEN IMPROVED. PEAK DISCHARGES AND TIMES MAY DIFFER FROM THE PREVIOUS VERSION. OUTPUT
HYDROGRAPHS ARE STILL INTERPOLATED, PRINTED, AND ROUTED AT THE USER SELECTED MAIN TIME INCREMENT.
INTERMEDIATE PEAKS - METHOD ADDED TO PROVIDE DISCHARGES AT INTERMEDIATE POINTS WITHIN REACHES WITHOUT ROUTING.
OTHER - THIS VERSION CONTAINS SOME ADDITIONS TO THE INPUT AND NUMEROUS MODIFICATIONS TO THE OUTPUT. USER
OPTIONS HAVE BEEN MODIFIED AND AUGMENTED ON THE JOB RECORD, RAINTABLES ADDED, ERROR AND WARNING MESSAGES
EXPANDED, AND THE SUMMARY TABLES COMPLETELY REVISED. THE HOLDOUT OPTION IS NOT OPERATIONAL AT THIS TIME.
PROGRAM QUESTIONS OR PROBLEMS SHOULD BE DIRECTED TO HYDRAULIC ENGINEERS AT THE SCS NATIONAL TECHNICAL CENTERS:
CHESTER, PA (NORTHEAST) -- 215-499-3933, FORT WORTH, TX (SOUTH) -- 334-5242 (FTS)

OR HYDROLOGY UNIT, ENGINEERING DIVISION, LANHAM, MD -- 436-7383 (FTS).
PROGRAM CHANGES SINCE MAY 1982:
12/17/82 - CORRECT PEAK RATE FACTOR FOR USER ENTERED DIMHYD
CORRECT REACH ROUTING PEAK TRAVEL TIME PRINTED WITH FULLPRINT OPTION
5/02/83 - CORRECT COMPUTATIONS FOR ---
1. DIVISION OF BASEFLOW IN DIVERT OPERATION
2. HYDROGRAPH VOLUME SPLIT BETWEEN BASEFLOW AND ABOVE BASEFLOW
3. CROSS SECTION DATA PLOTTING POSITION
4. INTERMEDIATE PEAK WHEN "FROM" AREA IS LARGER THAN "THRU" AREA
5. STORAGE ROUTED REACH TRAVEL TIME FOR MULTIPEAK HYDROGRAPH
6. ORDERING "FLOW-FREQ" FILE FROM SUMMARY TABLE #3 DATA
7. BASEFLOW ENTERED WITH READHYD ,
8. LOW FLOW SPLIT DURING DIVERT PROCEDURE #2 WHEN SECTION RATINGS START AT DIFFERENT ELEVATIONS
ENHANCEMENTS ---
1. REPLACE USER MANUAL ERROR CODES (PAGE 4-9 TO 4-11) WITH MESSAGES
2. LABEL OUTPUT HYDROGRAPH FILES WITH CROSS SECTION/STRUCTURE, ALTERNATE AND STORM NO'S
09/01/83 - CORRECT INPUT AND OUTPUT ERRORS FOR INTERMEDIATE PEAKS
CORRECT COMBINATION OF RATING TABLES FOR DIVERT
CHECK REACH ROUTING PARAMETERS FOR ACCEPTABLE LIMITS

COMPUTER PROGRAM FOR PROJECT FORMULATION - HYDROLOGY USER NOTES
THE USERS MANUAL FOR THIS PROGRAM IS THE MAY 1982 DRAFT OF TR-20. CHANGES FROM THE 2/14/74 VERSION INCLUDE:
REACH ROUTING - THE MODIFIED ATT-KIN ROUTING PROCEDURE REPLACES THE CONVEX METHOD. INPUT DATA PREPARED FOR
PREVIOUS PROGRAM VERSIONS USING CONVEX ROUTING COEFFICIENTS WILL NOT RUN ON THIS VERSION.
THE PREFERRED TYPE OF DATA ENTRY IS CROSS SECTION DATA REPRESENTATIVE OF A REACH. IT IS RECOMMENDED THAT
THE OPTIONAL CROSS SECTION DISCHARGE-AREA PLOTS BE OBTAINED WHENEVER NEW CROSS SECTION DATA IS ENTERED.
THE PLOTS SHOULD BE CHECKED FOR REASONABLENESS AND ADEQUACY OF INPUT DATA FOR THE COMPUTATION OF "M"
VALUES USED IN THE ROUTING PROCEDURE.
GUIDELINES FOR DETERMINING OR ANALYZING REACH LENGTHS AND COEFFICIENTS (X,M) ARE AVAILABLE IN THE USERS
MANUAL. SUMMARY TABLE 2 DISPLAYS REACH ROUTING RESULTS AND ROUTING PARAMETERS FOR COMPARISON AND CHECKING.
HYDROGRAPH GENERATION - THE PROCEDURE TO CALCULATE THE INTERNAL TIME INCREMENT AND PEAK TIME OF THE UNIT
HYDROGRAPH HAVE BEEN IMPROVED. PEAK DISCHARGES AND TIMES MAY DIFFER FROM THE PREVIOUS VERSION. OUTPUT
HYDROGRAPHS ARE STILL INTERPOLATED, PRINTED, AND ROUTED AT THE USER SELECTED MAIN TIME INCREMENT.
INTERMEDIATE PEAKS - METHOD ADDED TO PROVIDE DISCHARGES AT INTERMEDIATE POINTS WITHIN REACHES WITHOUT ROUTING.
OTHER - THIS VERSION CONTAINS SOME ADDITIONS TO THE INPUT AND NUMEROUS MODIFICATIONS TO THE OUTPUT. USER
OPTIONS HAVE BEEN MODIFIED AND AUGMENTED ON THE JOB RECORD, RAINTABLES ADDED, ERROR AND WARNING MESSAGES
EXPANDED, AND THE SUMMARY TABLES COMPLETELY REVISED. THE HOLDOUT OPTION IS NOT OPERATIONAL AT THIS TIME.
PROGRAM QUESTIONS OR PROBLEMS SHOULD BE DIRECTED TO HYDRAULIC ENGINEERS AT THE SCS NATIONAL TECHNICAL CENTERS:
CHESTER, PA (NORTHEAST) -- 215-499-3933, FORT WORTH, TX (SOUTH) -- 334-5242 (FTS)
LINCOLN, NB (MIDWEST) -- 541-5318 (FTS), PORTLAND, OR (WEST) -- 423-4099 (FTS)
OR HYDROLOGY UNIT, ENGINEERING DIVISION, LANHAM, MD -- 436-7383 (FTS).
PROGRAM CHANGES SINCE MAY 1982:
12/17/82 - CORRECT PEAK RATE FACTOR FOR USER ENTERED DIMHYD
CORRECT REACH ROUTING PEAK TRAVEL TIME PRINTED WITH FULLPRINT OPTION
5/02/83 - CORRECT COMPUTATIONS FOR ---
1. DIVISION OF BASEFLOW IN DIVERT OPERATION
2. HYDROGRAPH VOLUME SPLIT BETWEEN BASEFLOW AND ABOVE BASEFLOW
3. CROSS SECTION DATA PLOTTING POSITION
4. INTERMEDIATE PEAK WHEN "FROM" AREA IS LARGER THAN "THRU" AREA
5. STORAGE ROUTED REACH TRAVEL TIME FOR MULTIPEAK HYDROGRAPH
6. ORDERING "FLOW-FREQ" FILE FROM SUMMARY TABLE #3 DATA
7. BASEFLOW ENTERED WITH READHYD
8. LOW FLOW SPLIT DURING DIVERT PROCEDURE #2 WHEN SECTION RATINGS START AT DIFFERENT ELEVATIONS
ENHANCEMENTS ---
1. REPLACE USER MANUAL ERROR CODES (PAGE 4-9 TO 4-11) WITH MESSAGES
2. LABEL OUTPUT HYDROGRAPH FILES WITH CROSS SECTION/STRUCTURE, ALTERNATE AND STORM NOIS
09/01/83 - CORRECT INPUT AND OUTPUT ERRORS FOR INTERMEDIATE PEAKS
CORRECT COMBINATION OF RATING TABLES FOR DIVERT
CHECK REACH ROUTING PARAMETERS FOR ACCEPTABLE LIMITS
ELIMINATE MINIMUM REACH TRAVEL TIME WHEN ATT-KIN COEFFICIENT EQUALS ONE

COMPUTER PROGRAM FOR PROJECT FORMULATION - HYDROLOGY USER NOTES
THE USERS MANUAL FOR THIS PROGRAM IS THE MAY 1982 DRAFT OF TR-20. CHANGES FROM THE 2/14/74 VERSION INCLUDE:
REACH ROUTING - THE MODIFIED ATT-KIN ROUTING PROCEDURE REPLACES THE CONVEX METHOD. INPUT DATA PREPARED FOR
PREVIOUS PROGRAM VERSIONS USING CONVEX ROUTING COEFFICIENTS WILL NOT RUN ON THIS VERSION.
THE PREFERRED TYPE OF DATA ENTRY IS CROSS SECTION DATA REPRESENTATIVE OF A REACH. IT IS RECOMMENDED THAT
THE OPTIONAL CROSS SECTION DISCHARGE-AREA PLOTS BE OBTAINED WHENEVER NEW CROSS SECTION DATA IS ENTERED.
THE PLOTS SHOULD BE CHECKED FOR REASONABLENESS AND ADEQUACY OF INPUT DATA FOR THE COMPUTATION OF "M"
VALUES USED IN THE ROUTING PROCEDURE.
GUIDELINES FOR DETERMINING OR ANALYZING REACH LENGTHS AND COEFFICIENTS (X,M) ARE AVAILABLE IN THE USERS
MANUAL. SUMMARY TABLE 2 DISPLAYS REACH ROUTING RESULTS AND ROUTING PARAMETERS FOR COMPARISON AND CHECKING.
HYDROGRAPH GENERATION - THE PROCEDURE TO CALCULATE THE INTERNAL TIME INCREMENT AND PEAK TIME OF THE UNIT
HYDROGRAPH HAVE BEEN IMPROVED. PEAK DISCHARGES AND TIMES MAY DIFFER FROM THE PREVIOUS VERSION. OUTPUT
HYDROGRAPHS ARE STILL INTERPOLATED, PRINTED, AND ROUTED AT THE USER SELECTED MAIN TIME INCREMENT.
INTERMEDIATE PEAKS - METHOD ADDED TO PROVIDE DISCHARGES AT INTERMEDIATE POINTS WITHIN REACHES WITHOUT ROUTING.
OTHER - THIS VERSION CONTAINS SOME ADDITIONS TO THE INPUT AND NUMEROUS MODIFICATIONS TO THE OUTPUT. USER
OPTIONS HAVE BEEN MODIFIED AND AUGMENTED ON THE JOB RECORD, RAINTABLES ADDED, ERROR AND WARNING MESSAGES
EXPANDED, AND THE SUMMARY TABLES COMPLETELY REVISED. THE HOLDOUT OPTION IS NOT OPERATIONAL AT THIS TIME.
PROGRAM QUESTIONS OR PROBLEMS SHOULD BE DIRECTED TO HYDRAULIC ENGINEERS AT THE SCS NATIONAL TECHNICAL CENTERS:
CHESTER, PA (NORTHEAST) - 215-499-3933, FORT WORTH, TX (SOUTH) -- 334-5242 (FTS)
LINCOLN, NB (MIDWEST) -- 541-5318 (FTS), PORTLAND, OR (WEST) -- 423-4099 (FTS)
OR HYDROLOGY UNIT, ENGINEERING DIVISION, LANHAM, MD -- 436-7383 (FTS).
PROGRAM CHANGES SINCE MAY 1982:
12/17/82 - CORRECT PEAK RATE FACTOR FOR USER ENTERED DIMHYD
CORRECT REACH ROUTING PEAK TRAVEL TIME PRINTED WITH FULLPRINT OPTION
5/02/83 - CORRECT COMPUTATIONS FOR ---
1. DIVISION OF BASEFLOW IN DIVERT OPERATION
2. HYDROGRAPH VOLUME SPLIT BETWEEN BASEFLOW AND ABOVE BASEFLOW
3. CROSS SECTION DATA PLOTTING POSITION
4. INTERMEDIATE PEAK WHEN "FROM" AREA IS LARGER THAN "THRU" AREA
5. STORAGE ROUTED REACH TRAVEL TIME FOR MULTIPEAK HYDROGRAPH
6. ORDERING "FLOW-FREQ" FILE FROM SUMMARY TABLE #3 DATA
7. BASEFLOW ENTERED WITH READHYD
8. LOW FLOW SPLIT DURING DIVERT PROCEDURE #2 WHEN SECTION RATINGS START AT DIFFERENT ELEVATIONS
ENHANCEMENTS ---
1. REPLACE USER MANUAL ERROR CODES (PAGE 4-9 TO 4-11) WITH MESSAGES
2. LABEL OUTPUT HYDROGRAPH FILES WITH CROSS SECTION/STRUCTURE, ALTERNATE AND STORM NO'S
09/01/83 - CORRECT INPUT AND OUTPUT ERRORS FOR INTERMEDIATE PEAKS
CORRECT COMBINATION OF RATING TABLES FOR DIVERT
CHECK REACH ROUTING PARAMETERS FOR ACCEPTABLE LIMITS
ELIMINATE MINIMUM REACH TRAVEL TIME WHEN ATT-KIN COEFFICIENT EQUALS ONE

Guilford County
CERTIFIED MAIL-RETURN RECEIPT REQUESTED
Mr. Farrell Hanzeker
Greensboro Independent School Corp.
PO BOX 26805
Greensboro NC 27429
Dear Mr. Hanzeker.
The Division of Water Quality has reviewed your plans for the discharge of fill material into 410
feet of streams located at Lawndale Dr. and Lake Brandt Rd in Guilford County for school development.
Insufficient evidence is present in our files to conclude that your project must be built as planned in waters
and/or wetlands in accordance with 15A NCAC 2H .0506. Therefore, unless modifications of the proposal
are made as described below, we will have to move toward denial of your 401 Certification as required by
15A NCAC 2H.0507(e) and will place this project on hold as incomplete until we receive this additional
information, we are requesting (by copy of this letter) that the U. S. Army Corps of Engineers place your
project on administrative hold.
Please provide us with information supporting your position that states your project must be
constructed as planned and that you have no practicable alternative to placing fill in these waters and/or
wetlands. Specifically can your school site with less than 150 feet of stream impact? If not, then you will
need to construct a wet detention pond or similar stormwater management device that is designed to remove
85% TSS. Any documentation such as maps and narrative that you can supply to address alternative
designs for your project may be helpful in our review of your 401 Certification. Please respond within three
weeks of the date of this letter by sending a copy of this information to me and one copy to Ron Linville,
Winston -Salem Regional Office at 585 Waughtown Street Winston -Salem, NC 27107. If we do not hear
from you in three weeks, we will assume that you -no longer want to pursue this project and we will consider
the project as withdrawn. I can be reached at 919-733-1786 if you have any questions.

_
shelves are to be planted wath button bushes. Black willows and river birch (or similar sized species)
maybe planted in strategic locations for aesthetic and educational benefits. Wetlands included in
f and design are approved for wheel's enyironmental educational programs, A boardwalk may also
he installed for educational as well as O&M access
The school should he advised in the 401 certification that it would be beneficial to leave as many
trees along the upper portion of this stream as possible for streambank stability and pond water
quality,
