Dear Mr. Dorney
The intent of this letter serves as a request to remove the Deed Notification ouireementt
(Item #1 of NCDWQ letter dated August 13, 2001) for the referenced proje John suggested reading the Sample Deed Notification on your departments understand the details of the deed notification. It is our understanding that the
notifications' purpose is to safeguard the wetlands should the subject property be sold or
further subdivided.
Historically state owned universities do not sell their property. Rather than add
attachments to the University it would be appreciated if the deed notification could be
waived. The work for this project is approximately in the center of the campus and within
a regulated floodway. Disturbance or addition of fill in the area is unlikely due to local
restrictions. The elements associated with this project are also likely to be used by the
Biology departments' studies as a wetland/wildlife habitat thereby ensuring its intent and
integrity.
If there are any questions please do not hesitate to call.

Dear Mr. St. Johns:
Enclosed please find one (1) set of plans and supporting calculations for the Storm Water
Management Plan for the Science and Technology Building at the University of North Carolina
Charlotte. The plan is submitted to meet the conditions of Section 401, Water Quality
Certification; Additional Conditions as outlined in item 2 of your letter of August 13, 2001 (copy
Attached); the comments of your letter dated August 15, 2002 (copy Attached) and your
conversation with Peter Franz of UNCC confirmed in an email dated September 12, 2002 (copy
Attached).
This plan covers the entire area draining of the new construction. We are proposing one dry
detention basin followed by a vegetative filter strip to provide assumed 85% TSS treatment for
the total drainage area. This plan does not include any bioretention BMP facilities.
A copy of the executed and notorized Revised Operation and Maintenance Plan is included with
the calculations.
We trust this is sufficient information for your review and approval of this Storm Water
Management Plan. If there are any questions, corrections or additions, please feel free to contact
me at the above address, by phone at [phone], by fax number at [phone] or Email

Subject: UNCC
DWO Project No. 011020
Mecklenburg County
The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined that additional
information is necessary to complete the technical review process. The required additional information is as follows:
1. Final Plan
The 401 Water Quality Certification issued August 13, 2001 a "final' stormwater management plan. The plans
submitted seem to include the use of bioretention areas; however, no plans were submitted.
2. Dry Detention
Based on my calculations, the volume to be detained in the dry detention basin would be approximately 53,000
cubic feet. Only 23,000 cubic feet of storage is proposed. As such, insufficient storage is proposed.
Sediment Storage
Sediment storage equal to 20% of the detention volume must be provided.
4. Planting/Seeding Plan
Please provide a planting or seeding plan that indicates species appropriate for inundation.
5. Operation and Maintenance Agreement
An operation and maintenance agreement must include language regarding the maintenance of the proposed level
:,preader. An example agreerrieni for an extended detention wet pond is available on line at
http://h2o.enr.state.nc.us/ncwetlands/oandm.doc.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of receipt of the
requested information. Completing the enclosed worksheet (also available on line at the address below) will greatly
decrease the staff review time. If you have any questions or would like to discuss this project, please contact me at (919)
733-9584. Also, please note that the NCDENR Stormwater Best Management Practices Manual, April 1999, and other

Subject: Science and Technology Storm Water Management Basin DWQ. Project
Todd,
This email is to verify our phone conversation on September 12, 2002 concerning the referenced
project.
It is understood that the size of the dry basin being designed by Law Engineering is to retain the entire
drainage area of approximately 27 acres.
This will account for 50% of the tss. The level spreader located at the outlets of the dry basin will
account for 35% of the tss thereby fulfilling the requirement to suspend 85% of the tss.
The bio-retention basins indicated in the first submittal by Law Engineering are not required for this
project.
Please let me know if I have not interpreted out conversation correctly so that we may design the
plans as required.

SCIENCE AND TECHNOLOGY BUILDING COMPLEX
STORM WATER MANAGEMENT PLAN
Background:
The UNC Charlotte Master Plan has defined an Academic Core that will provide a
pedestrian oriented campus and limited vehicular traffic. The Academic Core is
delineated by the streets currently named Cameron Boulevard, Craver Rd., Mary
Alexander Rd. and University Rd. In 1998 Craver Rd. was realigned with Cameron Blvd.
to form a ` T ` intersection. This intersection followed the Master Plan goal to create a
building area that will allow the Science and Technology Building to be constructed.
One of the Planning Assumptions of the Master Plan is to group buildings of similar
disciplines. The Burson Building, located to the east houses the Physical Sciences
departments. Some of the departments will be relocating in the Science and Technology
Building. The area between the intersection of Cameron Blvd., Craver Rd. and the
Burson Building is the last remaining building areas within the Academic Core that can
be associated with the sciences.
Using the " Sustainable Site Planning Targets " recommended by the State, the
University is working to accomplish as many of these goals as possible. With this
particular project, we are attempting to balance the minimization of environmental
systems, situating the building to benefit from existing vegetation, minimizing paving
areas and avoiding cut and fill. By studying the site and locating the building at its
current location it has managed to retain as much of the stream as possible and retain
valuable existing vegetation. The service area is located to minimize paving by placing it
at elevations easily accessible to Craver Rd. To shift the building any further north or
west will result in a substantial increase in earthwork and cost to the project.
Storm Water Management Plan:
The project drainage area leading down to Toby Creek comprises twenty-seven (27) acres
of the Academic Core area as delineated above. Most of the project drainage area is
existing campus area with the characteristics as outlined on the "Drainage Area
Characteristics and BMP Design Calculations" form attached. The existing impervious
area is forty-four (44%) percent of the total project drainage area. The current building
project is for the Science and Technology Building. A future building project is proposed
for two Nursing and Education buildings. The additional impervious area for the current
project includes 1.1 acres of buildings and 1.3 acres of walks, etc. The additional
impervious area for the future project includes 1.4 acres of buildings but will replace 1.0
acres of existing impervious area. The future total impervious area will be 14.7 acres or
54.4% of the project drainage area.
The lower portion of the project drainage area does not lend itself to development of a
wet detention pond as there is a sanitary sewer line traversing the area. However there is
enough area out side of the sanitary sewer easement to install a dry detention basin to
serve the drainage area. Also the natural stream channel bank buffer lends itself for use
as a filter strip. The dry basin will need to have the sediment removed once it reaches an
elevation of 599.75 MSL.
The proposed vegetation shown on the "Landscape Plan" were specifically selected by
the project Landscape Architect for their ability to endure periodic inundation for short
periods of time.
The design calculations for the dry detention basin and filter strip are attached. The
"Division of Water Quality - 401 Detention Basin Worksheet" and "Detention Basin
Supplement" are attached for the dry detention basin. These forms also include the
operation and maintenance agreement for the dry detention basin. Detailed design
calculations for the dry detention basin and filter strip are also attached.

DRY [WETLAND] DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
" [Wetland maintenance wording is bracketed. Please modify the document as appropriate.]
,-Jie dry [wetland] detention basin system is defined as the dry [wetland] detention basin, pretreatment
including forebays and the vegetated filter if one is provided.
Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the dry [wetland] detention basin system for sediment accumulation, erosion, trash
accumulation, vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
.2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow
vegetative cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the dry [wetland] detention basin system semi-annually or when
depth is reduced to 75% of the original design depth (see diagram below). Removed sediment shall be
disposed of in an appropriate manner and shall be handled in a manner that will not adversely impact
water quality (i.e. stockpiling near a dry [wetland] detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads N/A _ feet in the main pond, the sediment shall be removed.
[For stormwater wetlands: If the elevation of the marsh areas exceed the permanent pool elevation, the
sediment should be removed to design levels. This shall be performed by removing the upper 6 inches of
soil and stockpiling it. Then the marsh area shall be excavated six inches below design elevations.
Afterwards the stockpiled soil should be spread over the marsh surface. The soil should not be stockpiled
for more than two weeks.]
When the permanent pool depth reads N/A _ feet in the forebay [and micro-pool], the sediment shall
be removed.

.emove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
r
[For wetlands: Wetland planting densities in the marsh areas should be maintained by replanting bare
areas as needed. Wetland plants should be encouraged to grow in the marsh areas.]
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain shall be minimized to the maximum extent practical.
7. All components of the dry [wetland] detention basin system shall be maintained in good working order.
8. Level spreaders or other structures that provide diffuse flow shall be maintained every six months. All
accumulated sediment and debris shall be removed from the structure, and a level elevation shall be
maintained across the entire flow spreading structure. Any down gradient erosion must be repaired and/or
replanted as necessary.
I acknowledge and agree by my signature below that I am responsible for the performance of the seven
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.

Dear Mr. Eute:
UNCC
DWQ Project No. 011020
Mecklenburg County
The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined that additional
information is necessary to complete the technical review process. The required additional information is as follows:
Final Plan
The 401 Water Quality Certification issued August 13, 2001 a "final" stormwater management plan. The plans
submitted seem to include the use of bioretention areas; however, no plans were submitted.
2. Dry Detention
Based on my calculations, the volume to be detained in the dry detention basin would be approximately 53,000
cubic feet. Only 23,000 cubic feet of storage is proposed. As such, insufficient storage is proposed.
3. Sediment Storage
Sediment storage equal to 20% of the detention volume must be provided.
4. Planting/Seeding Plan
Please provide a planting or seeding plan that indicates species appropriate for inundation.
5. Operation and Maintenance Agreement
An operation and maintenance agreement must include language regarding the maintenance of the proposed level
spreader. An example agreement for an extended detention wet pond is available on line at
hftp://h2o.enr.state.nc.us/ncwetlands/oandm.doc.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of receipt of the
requested information. Completing the enclosed worksheet (also available on line at the address below) will greatly
decrease the staff review time. If you have any questions or would like to discuss this project, please contact me at (919)
733-9584. Also, please note that the NCDENR Stormwater Best Management Practices Manual, April 1999, and other
documents and information can be downloaded from the Wetlands Unit web site at

Bioretention areas in the campus area to provide assumed 85%-.TSS-treatment for the remaining
15 acres, of the totaldrainage area,
A copy of the executed and notorized Operation and Maintenance Plan is included with the
calculations.
We trust this is sufficient information for your review and approval of this Storm Water

Charlotte, NC 28223-0001
Dear Mr. Franz
You have our approval, in accordance with the attached conditions and those listed below, to place fill material in 269 linear feet
of streams for the purpose of constructing the Science and Technology Building at UNC-C as described in your application dated July
2, 2001 and revised on August 9, 2001. After reviewing your application, we have decided that this fill is covered by General Water
Quality Certification Number 3287. This certification allows you to use Nationwide Permit Number 39 when the Corps of Engineers
issues it In addition, you should get any other federal, state or local permits before you go ahead with your project including (but not
limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Water shed regulations. This
approval.will expire when the accompanying 404 or CAMA permit expires unless otherwise specified In the General
Certification.
This approval is only valid for the purpose and design that you described in your application except as modified below. If you
change your project, you must notify us and you may be required to send us a new application. If the property is sold, the new owner
must be given a copy of this Certification and approval letter and is thereby responsible for complying with all conditions. If total
wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A
NCAC 2H .0506 (h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the attached certification and any
additional conditions listed below. _
1. Deed notifications or similar mechanisms shall be placed on all remaining jurisdictional wetlands and streams to notify the state in
order to assure compliance for future wetland and/or water impact These mechanisms shall be put in place within 30 days of the
date of this letter or the issuance of the 404 Permit (whichever is later).
2. An additional condition is that a final, written stormwater management plan shall be approved by this Office before the impacts
specified in this Certification occur. The stormwater management plan must include plans and specifications for stormwater
management facilities designed to remove 85% TSS according to the most recent version of the NC DENR Stormwafer Best
Management Pracdces Manual. Also, before any permanent building is occupied at the subject site, the facilities, as approved by
this Office, shall be constructed and operational, and the stormwater management plan, as approved by this Office, shall be
implemented.
3. Compensatory stream mitigation will not be required by DWQ but may be required by the U.S. Army Corps of Engineers.
4. Upon completion of the project, the applicant shall complete and return the enclosed 'Certification of Completion Form' to notify

SCIENCE AND TECHNOLOGY BUILDING COMPLEX
STORM WATER MANAGEMENT PLAN
Background:
The UNC Charlotte Master Plan has defined an Academic Core that will provide a
pedestrian oriented campus and limited vehicular traffic. The Academic Core is
delineated by the streets currently named Cameron Boulevard, Craver Rd., Mary
Alexander Rd. and University Rd. In 1998 Craver Rd. was realigned with Cameron Blvd.
to form a ` T ` intersection. This intersection followed the Master Plan goal to create a
building area that will allow the Science and Technology Building to be constructed.
One of the Planning Assumptions of the Master Plan is to group buildings of similar
disciplines. The Burson Building, located to the east houses the Physical Sciences
departments. Some of the departments will be relocating in the Science and Technology
Building. The area between the intersection of Cameron Blvd., Craver Rd. and the
Burson Building is the last remaining building areas within the Academic Core that can
be associated with the sciences.
Using the " Sustainable Site Planning Targets " recommended by the State, the
University is working to accomplish as many of these goals as possible. With this
particular project, we are attempting to balance the minimization of environmental
systems, situating the building to benefit from existing vegetation, minimizing paving
areas and avoiding cut and fill. By studying the site and locating the building at its
current location it has managed to retain as much of the stream as possible and retain
valuable existing vegetation. The service area is located to minimize paving by placing it
at elevations easily accessible to Craver Rd. To shift the building any further north or
west will result in a substantial increase in earthwork and cost to the project.
Storm Water Management Plan:
The project drainage area leading down to Toby Creek comprises twenty-seven (27) acres
of the Academic Core area as delineated above. Most of the project drainage area is
existing campus area with the characteristics as outlined on the "Drainage Area
Characteristics and BMP Design Calculations" form attached. The existing impervious
area is forty-four (44%) percent of the total project drainage area. The current building
project is for the Science and Technology Building. A future building project is proposed
for two Nursing and Education buildings. The additional impervious area for the current
project includes 1.1 acres of buildings and 1.3 acres of walks, etc. The additional
impervious area for the future project includes 1.4 acres of buildings but will replace 1.0
acres of existing impervious area. The future total impervious area will be 14.7 acres or
54.4% of the project drainage area.
The lower portion of the project drainage area does not lend itself to development of a
wet detention pond as there is a sanitary sewer line traversing the area. However there is
enough area out side of the sanitary sewer easement to install a dry detention basin to
serve 12 acres of the drainage area. Also the natural stream channel bank buffer lends
itself for use as a filter strip, which would provide treatment for 12 acres of the drainage
area. Both the dry detention basin and the filter strip constitute BMP's appropriate for
the mitigation of storm water flow for the project area. These two BMP's will provide
85% assumed TSS removal for 12 acres. To increase the assumed TSS removal,
bioretention areas in the campus area will be designed to provide treatment for an
additional 15 acres. With the addition of these bioretention areas in the campus area the
provided assumed TSS removal will be brought to 85% for the entire drainage area. (See
the "Drainage Area Characteristics and BMP Design Calculations" form attached.) The
bioretention area are to be designed by the site design and grading engineers for the
various buildings currently and future proposed for construction in the campus core area.
The design calculations for the dry detention basin and filter strip are attached. The
"Division of Water Quality - 401 Detention Basin Worksheet" and "Detention Basin
Supplement" are attached for the dry detention basin. These forms also include the
operation and maintenance agreement for the dry detention basin. Detailed design
calculations for the dry detention basin and filter strip are also attached. In addition
attached is a map which shows the potential locations for adequate bioretention areas to
cover more than 15 acres of campus core area.

Footnotes:
When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.

APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS
Peter Franz
Facilities Landscape Architect
University of North Carolin-Charlotte
9201 University City Boulevard
Charlotte, NC 28223-0001
Dear Mr. Franz:
You have our approval, in accordance with the attached conditions and those listed below, to place fill material in 269 linear feet
of streams for the purpose of constructing the Science and Technology Building at UNC-C as described in your application dated July
2, 2001 and revised on August 9, 2001. After reviewing your application, we have decided that this fill is covered by General Water
Quality Certification Number 3287. This certification allows you to use Nationwide Permit Number 39 when the Corps of Engineers
issues it. In addition, you should get any other federal, state or local permits before you go ahead with your project including (but not
limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Water shed regulations. This
approval will expire when the accompanying 404 or CAMA permit expires unless otherwise specified in the General
Certification.
This approval is only valid for the purpose and design that you described in your application except as modified below. If you
change your project, you must notify us and you may be required to send us a new application. If the property is sold, the new owner
must be given a copy of this Certification and approval letter and is thereby responsible for complying with all conditions. If total
wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A
NCAC 2H .0506 (h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the attached certification and any
additional conditions listed below.
1. Deed notifications or similar mechanisms shall be placed on all remaining jurisdictional wetlands and streams to notify the state in
order to assure compliance for future wetland and/or water impact. These mechanisms shall be put in place within 30 days of the
date of this letter or the issuance of the 404 Permit (whichever is later).
2. An additional condition is that a final, written stormwater management plan shall be approved by this Office before the impacts
specified in this Certification occur. The stormwater management plan must include plans and specifications for stormwater
management facilities designed to remove 85% TSS according to the most recent version of the NC DENR Stormwater Best
Management Practices Manual. Also, before any permanent building is occupied at the subject site, the facilities, as approved by
this Office, shall be constructed and operational, and the stormwater management plan, as approved by this Office, shall be
implemented.
3. Compensatory stream mitigation will not be required by DWQ but may be required by the U.S. Army Corps of Engineers.
4. Upon completion of the project, the applicant shall complete and return the enclosed "Certification of Completion Form" to notify
DWQ that all the work included in the 401 Certification has been completed. The responsible party shall complete the attached
form and return it to the 4011Wetlands Unit of the Division of Water Quality.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act within 60
days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to Chapter 150B of the North
Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. This certification and
its conditions are final and binding unless you ask for a hearing.

CERTIFIED MAIL-RETURN RECEIPT REQUESTED
Mr. Olen Smith
Vice Chancellor-Business Affairs
UNC-Charlotte
9201 University City Blvd.
Charlotte, NC 28223-0001
Dear Mr. Smith:
The Division of Water Quality has reviewed your plans for the discharge of fill material into 269 linear feet of streams located
at UNC-Charlotte campus in Mecklenburg County for construction of a new science building. 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 you provide stormwater
management for this new building or an equivalent amount of existing impervious surface on campus. Without this stormwater
management, this 401 Certification cannot be issued. 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. Also this project will require compensatory
mitigation as described in 15A NCAC 2H .0506(h). Your mitigation proposal is insufficient because your proposal is not stream
restoration and would be of little benefit to Toby Creek.
Please respond within three weeks of the date of this letter by sending a copy of this information to me and one copy to
Mooresville Regional. 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. If you have any questions, please telephone Todd St John at 919-733-9584 or Pete Colwell at
our Mooresville Regional Office at 704-663-1699.

On behalf of UNC Charlotte, Law Engineering and Environmental Services submitted the
Referenced project on July 2, 2001. Through conversations with Peter Colwell of NCDENR it is
the Universities understanding that a Storm-water Management Plan will be required. It is
understood that the plan will include a filtering basiu to filter 0.85% of suspended solids and a
maintenance manual.
It is the Universities intent to have the Storm-water Plan designed to comply with the Best
Management practice publication issued by NCDENR dated April 1999.
The Basin will be located at tho outfall of an existing storm drainage pipe on the west side of
Cameron Boulevard, (See attachment 1). The basin will be designed for the project area noted in
Law Enginccriug's Permit Application but will consider the overall drainage area draining into
the stream channel. The basin will be complcted prior to occupancy of the building.
We respectively ask that the University of North Carolina at Charlotte be issued a Nationwide
Permit No. 39 in order to keep this project on schedule.
Thank you for you assistance

Comments:
The applicant is proposing to pipe 269 linear feet of a small perennial tributary to Toby Creek on the
campus of l INC-Charlotte in order to construct a new Science Building. The stream has been
altered by man's activities in the past and carries a Iaroe volume of stormwater runoff from west side
of the campus. No significant aquatic life was found in the stream during a site investigation.
Water quality problems _and_the volume of stormwater has likely eliminated most of the aquatic
species jn the stream. Below the project site the channel has been piped under adjacent streets and
an athletic field and flows through approximately 300 feet of concrete channel before emptying into
Toby Greek, Toby Creek is a large urban stream heavily influenced by stormwater and has been
channeljzed through the athletic complex on campus.

,omments (continued from page 1):
Jniversity staff have indicated the lack of space and other "problems" associated with doing
itormwater treatment for the project. The MRO feels strongly that the project warrants some
itormwater treatment and has suggested a number of possiblities to the University staff Stormwater
-unoff from the campus would appear to be a major factor in the degredation of the small stream as
yell as Toby Creek.
Che applicant has imposed to mitigate by doing bank stabilization along Toby Greek. The area
imposed for bank stabilization along Toby Creek has some bank failure as well a areas where the
yanks are relative ly stable. Toby Creek is trying to re-establish a meandering channel at its existing
?levation and the the bank stability problems will continue. It is the opinion of this office that the
)roposed "enhanc ement" will do little to improve the water quali of Toby Creek.

In regards to the stormwater and stream mitigation proposed:
The stream mitigation proposed appears to be inadequate and probably inappropriate. They have
asked for 1:1 credit to plant and preserve a small reach of Toby Creek. This would either be 5:1 or
10:1 credit, respectively. Also, the straightened appearance of the creek and the failing banks shown
in the photos indicates that restoration of the creek is needed and, as such, enhancement by planting
or preservation would be inappropriate. The applicant proposed no stormwater plan. They seem to be
claiming that the project will be 24% impervious. It is not clear if all impervious areas were accounted
for in that determination. More detailed building and landscaping plans should be provided for us to
make that determination.

On behalf of the University of North Carolina at Charlotte (UNCC), enclosed please find a completed
Pre-Construction Notification (PCN) Application joint form (Attachment A) with accompanying
figures (Attachment B), for a Nationwide Permit (NWP) No. 39 in the above-referenced matter.
UNCC has retained Law Engineering and Environmental Services, Inc. (LAW) to provide Section
404 permitting services for this project. The project site is located on the UNCC campus in Charlotte,
Mecklenburg County, North Carolina, between the Barnhardt Student Activity Center and Michael
Ray Craver Road (Attachment B - Figures I and 2). UNCC has proposed the construction of a
180,982 square foot (sf) (47,500 sf footprint), four story building north of the Barnhardt Student
Activity Center. The proposed project will impact jurisdictional waters of the U.S., including
important jurisdictional stream below the ordinary high water mark, and wetlands. This letter will
serve as the pre-construction notification (PCN) and is provided pursuant to the notification
requirements of NWP No. 39, which requires the permittee to notify the District Engineer for
discharges causing the loss of any open waters, including perennial or intermittent streams, below the
M
ordinary high water mark (Federal Register, Vol. 65, No. 47; March 9, 2000).
Background
UNCC has proposed the construction of the Science and Technology Building on the subject site.
The approximate 6.5-acre project site is bounded by Michael Ray Craver Road to the north, the
Barnhardt Student Activity Center and access road to the south, Cameron Boulevard to the west, and

LAW Project 30100-1-0345
an undeveloped portion of the UNCC campus maintained in grass to the east. The proposed project
represents the most feasible alternative to provide UNCC with necessary classroom space. UNCC has
the largest deficit of classroom space among the 16 UNC campuses; the deficit is even greater in
teaching laboratory space (University of North Carolina Space Planning Standards). The project
would provide space for departments and programs in science and engineering, including the School
of Technology, and doctoral programs in Electrical Engineering and Biology. Current enrollment in
graduate and doctoral programs at UNCC is 2,711, with projected increase to 4,600 by 2006.
The siting of the building necessitates an unavoidable impact to jurisdictional waters of the U.S.
Completion of this project involves grading, paving, storm drainage improvements, and curb and
gutter for the proposed building, and associated service court and driveway.
Jurisdictional Waters of the U.S.
On April 26, 2001, LAW'S Mr. Adam Karagosian and Ms. Catherine McRae, field delineated the
jurisdictional boundaries of waters of the U.S., including wetlands, within the project site. The
wetland area was delineated using the Routine On-Site Determination Method as described in the
1987 "Corps of Engineers Wetland Delineation Manual."t Routine Wetland Determination Forms
are included in Attachment C. Reference Attachment C, Figure 3, Approximate Waters of the U.S.
and Wetlands Boundary Map.
Jurisdictional waters of the U.S. associated with the proposed building and maintenance court include
an important jurisdictional stream and an adjacent wetland area. The stream is generally
characterized by the following dimensions: two to four foot wide channel bottom width; one to three
foot bank heights; width of three to four feet approximated from top of bank to top of bank; unstable,
eroded banks; flowing water in the channel; course sand and gravel substrate, and riffle-pool and step-
pool sequences. No fish, crayfish or shellfish were observed. Reference Attachment C.
The riparian canopy along the stream channel is comprised of several scattered trees, ranging from 8
to 24 inches diameter at breast height, which provide an estimated 75 percent canopy closure. The

riparian canopy includes sugar maple (Acer saccharuni), sweetgum (Liquidambar styraciua), green
ash (Fraxinus pennsylvanica), black willow (Salix nigra), and willow oak (Quercus phellos). Ground
cover adjacent to the channel includes fescue (Festuca sp.), rushes (Juncus sp.), carex sedge (Carex
sp.), hairy buttercup (Ranunculus sardous), white clover (Trifoliwn repens) and common vetch (Vicia
saliva).
Based on the completed delineation, the wetland area is approximately 0.08 acre in size, and is
adjacent to the aforementioned stream channel. The wetland area is emergent, dominated by rushes,
carex sedge, and hairy buttercup, with a few scattered sweetgum trees (Attachment D).
According to the Soil Survey of Mecklenburg County, North Carolina (U.S. Department of
Agriculture, 1980), soils on the subject site are mapped as Wilkes loam, 8 to 15 percent slopes
(WkD), and 15 to 25 percent slopes (WkE) (Attachment B - Figure 2). Field observations within the
aforementioned wetland area identified hydric soils, with low chroma colors and bright mottles.
On May 24, 2001, Mr. Steve Chapin of the U.S. Army Corps of Engineers (USACE) visited the
subject site for the purpose of providing a jurisdictional determination of waters of the U.S., including
wetlands, on-site. Mr. Chapin verified LAW's delineation of the stream and adjacent wetland area.
Mr. Chapin also determined the stream to be an important, jurisdictional stream channel.
On June 15, 2001, Mr. Pete Colwell of the North Carolina Division of Water Quality's (DWQ)
Mooresville Regional Office visited the subject site for the purpose of assessing the subject stream
and discussing the proposed project with representatives of LAW and UNCC. Mr. Colwell found no
fish, shellfish, crayfish, or other large invertebrates in the stream, and concluded the stream to non-
perennial. Mr. Colwell further indicated that no mitigation would be required by DWQ for stream
impacts on the subject site.
Proposed Impacts to Jurisdictional Waters of the U.S.
The proposed project consists of a 180,982 square foot (sf) (47,500 sf footprint), four story building,
associated service court and driveway, curb and gutter, and drainage improvements. The proposed
project will result in unavoidable impacts to the jurisdictional stream. Construction of the service

court, loading docks, and driveway will require that a limited area of jurisdictional waters of the U.S.
be culverted and filled (Attachment B - Exhibits 1, 1 A, and 2, prepared by the Facilities Planning and
Construction Department of UNCC). Approximately 269 linear feet of the existing channel will be
impacted by the placement of a 36-inch reinforced concrete pipe (RCP), which will redirect water
around the existing channel. The existing channel will be filled with clean fill material. The entire
0.08-acre wetland area will be filled for grading purposes.
Regulatory Implications
Activities on the subject site involving impacts to waters of the U.S., will be required to follow the
General Conditions of the Nationwide Permits (Federal Register, Vol. 65, No. 47; March 9, 2000) and
State Consistency Conditions, as applicable.
Considering that proposed stream impacts would be greater than 150 linear feet, in accordance with
the conditions of Section 401 General Certification (GC) for a project eligible for NWP No. 39,
effective June 1, 2000, this application is also being provided to the North Carolina Department of
Environment and Natural Resources DWQ. The project complies with the conditions of the Section
401 GC.
Avoidance and Minimization
The UNC Charlotte Master Plan has defined an Academic Core that will provide a pedestrian oriented
campus and limiting vehicular traffic. The Campus Core is delineated by the streets currently named
Cameron Boulevard, Craver Road, Mary Alexander Road and University Road. In 1998, Craver Road
was realigned with Cameron Boulevard to form a `T` intersection. This intersection followed the
Campus Plan goal to create a building area that will allow the Science and Technology Building to be
constructed.
One of the Planning Assumptions of the Campus Master Plan is to group buildings of similar
disciplines. The Burson Building, located to the east of the project area, houses the Physical Sciences
departments. Some of the departments will be relocating in the Science and Technology Building.
The area between the intersection of Cameron Boulevard, Craver Road and the Burson Building is the
4

UNCC Science & Technology Building - NfVP No. 39 PCN July 2, 2001
LAW Project 30100-1-0345
last remaining building areas within the Academic Core that can be associated with the sciences.
Functions within the building require that a service area and delivery dock be provided. It is
anticipated that semi-trailer trucks will occasionally deliver large pieces of equipment. To maximize
contiguous academic space on the second, third and fourth floors of the building, the service area is
placed in the basement level that also provides better access to Craver Road.
Preliminary alternatives for the building found that it impacted the existing stream and caused the
removal of some existing large trees. This placement of the building was initially selected to attempt
to balance the earthwork. It was subsequently determined that by moving the building to the
northwest that the stream impacts would be reduced and a group of large trees would be saved. The
trees would reduce solar gain of the east side of the building. However, by moving the building to the
current location there is a subsequent increase of fill soil required.
Using the "Sustainable Site Planning Targets" recommended by the State, the University is working
to accomplish as many of these goals as possible. With this particular project UNCC is attempting to
balance the minimization of environmental systems (e.g., air conditioning, etc.), situating the building
to benefit from existing vegetation, minimizing paving areas and avoiding cut and fill. By studying
the site and siting the building at its current location UNCC has managed to retain as much of the
stream as possible and retain valuable existing vegetation. The service area is located to minimize
paving by placing it at elevations easily accessible to Craver Road. To shift the building any further
north or west will result in a substantial increase in earthwork and cost to the project.
Compensatory Mitigation - Conceptual Plan
The applicant proposes to provide enhancement and preservation of Toby Creek, located downstream
of the subject site on the UNCC campus, at a 1:1 ratio as compensatory mitigation. The specific
location of the proposed enhancement activities would occur in the vicinity of the confluence of the
outlet of the unnamed tributary and Toby Creek and extend approximately 269 If upstream. This
portion of Toby Creek is generally characterized by the following dimensions: 10 to 12 foot wide
channel bottom width; 8 to 10 foot bank heights; and width of approximately 20 to 25 feet
approximated from top of bank to top of bank. Enhancement efforts would involve streamside buffer
plantings and removal of debris. The purpose of the enhancement will be to improve water quality by
5

I
UNCC Science & Technology Building - NWP No. 39 PCN July 2, 2001
LAW Project 30100-1-0345
improving terrestrial and aquatic habitat through planting native trees along the stream channel. The
applicant proposes to maintain a 50-foot wide vegetated buffer on either side of the enhanced portion
of Toby Creek. The proposed enhancement area currently contains little or no riparian cover along
Toby Creek (Attachment D - Photographs 4 and 5). Table 1, found in Attachment E, lists woody
species likely to be planted.
As indicated by Mr. Colwell on June 15, 2001, no compensatory mitigation is required by DWQ for
on-site stream impacts.
Possible sedimentation of the channel adjacent to the construction area during and immediately
following the construction phase of this project will be minimized by strict implementation and
compliance with a State-approved sediment and erosion control plan.
Erosion and sediment control measures in this plan include the installation of temporary sediment
fence around portions of the construction area, and the use of temporary sediment basins to prevent
sedimentation to adjacent and downstream areas. Erosion and sediment control devices will be
inspected for compliance with the construction contract documents during and after construction, as
well as following major storm events, to identify needed repair, maintenance, or redesign.
Storm Water Management
UNCC's Facilities Planning and Construction Department has evaluated existing and proposed storm
water conditions on the subject site. The site is located on a hill, drains to three different collection
points, and is bounded by two existing streets at the lower elevations. Most of the project area is not
draining into the channel and would not impact water quality (Attachment C - Exhibit 1).
Investigation into the history of the area was done to determine if the channel was originally a wet
weather ditch or perennial. A Mecklenburg County topographic map from 1966 (map no. 1480-569)
did not indicate that the channel was perennial. Aerial photographs indicate that the area surrounding
the existing channel were farmed and that the woods that currently exist have been relatively
undisturbed.
6
UNCC Science & Technology Building - NWP No. 39 PCN July 2, 2001
' LAW Project 30100-1-0345
' The Mecklenburg County topographic map indicated that a farm road was located to the west of the
channel. This road appears to have been utilized during early construction of the campus based on
' aerial photographs taken at that time. Based on an observation by Mr. Colwell of DWQ on June 15,
2001, some of the channel appears to have been historically filled, this would coincide with the
' comments above. The channel currently begins at the outlet of a storm drainage pipe at the base of a
fill slope further up the hill. The existing channel appears to have been formed from the concentration
of storm water runoff from the campus as it developed.
It is the Universities understanding that a Storm Water Management Plan is required when the
impervious area exceeds 30% of the project area. The difficulty in determining this project area is
that it is located in the middle of the campus. There are limits that can be defined by physical
boundaries adjacent to the site such as Cameron Boulevard and Craver Road, existing buildings,
parking and an area that is required for construction equipment to operate safely. The latter is the
' approach used to calculate the Science and Technology project area. Surface runoff will flow through
grass swales and be collected into area drains on the east and south side of the building to assist in
' sediment collection.
' Below are areas used to determine the need for a Storm Water Management Plan.
' Project Area 6.5 acres
Proposed Roof Area 1.0 acre
' Proposed Brick Paving 0.34 acre
Proposed Service Drive 0.24 acre
Impervious area 24%
It would be difficult to implement a Storm Water Management Plan because:
1. The only level area adjacent to the building that could be utilized as a basin is near the
intersection of Cameron Boulevard and Craver Road. This area is remote from most of
the drainage systems and would be difficult to drain to.
2. The other level area that could be utilized for a wet basin exists on the west side of
Cameron Boulevard. This area is within a Regulated Floodplain (see Attachment B -
7
UNCC Science & Technology Building - NWP No. 39 PCN July 2, 2001
' LAW Project 30100-1-0345
' Exhibit 2). Toby Creek has flooded this area of campus within the last few years several
times. A storm-water management system designed to retain 85% of suspended solids
would be jeopardized if it were installed in this area.
' Considering that impervious surface accounts for less than 30% of the project area, and since 63% of
the impervious surface runoff will emanate from rooftops (and is therefore anticipated to be of
relatively high quality), post construction storm water management is not proposed.
' Environmental Assessment
In accordance with the "Environmental Assessment Guidelines" issued in March 1999 by the NC
' Department of Administration, UNCC prepared and submitted to the North Carolina State
Clearinghouse, an Environmental Assessment (EA) for the proposed project. A Finding of No
' Significant Impact (FONSI) was issued to UNCC by the N.C. Department of Administration on June
5, 2001. A copy of the FONSI is included in Attachment F.

Impact Justification (Avoidance and Minimization)
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.
The proposed project involves the construction of an approximate 180,982 square foot (0) (47,500 sf footprint),
four story building, associated service court, loading dock, and driveway, curb and gutter, and drainaee
improvements. Approximately 269 linear feet of an existing jurisdictional stream channel will be impacted
by the placement of 36-inch reinforced concrete pipe (RCP), which will redirect water around the existing
channel. The existing channel will be filled with clean fill material. The entire 0.08-acre wetland area will be
filled for grading purposes.
The UNC Charlotte Master Plan has defined an Academic Core that will provide a pedestrian oriented
campus and limiting vehicular traffic. The Campus Core is delineated by the streets currently named
Cameron Boulevard, Craver Road, Marv Alexander Road and University Road. In 1998, Craver Road was
realigned with Cameron Boulevard to form a `T` intersection. This intersection followed the Campus Plan
goal to create a building area that will allow the Science and Technology Building to be constructed.
One of the Planning Assumptions of the Campus Master Plan is to group buildings of similar disciplines. The
Burson Building, located to the east of the proiect area, houses the Physical Sciences departments. Some of
these departments will be relocating in the Science and Technology Building. The area between the
intersection of Cameron Boulevard, Craver Road and the Burson Building is the last remaining building
areas within the Academic Core that can be associated with the sciences. Functions within the building
require that a service area and delivery dock be provided. It is anticipated that semi-trailer trucks will
occasionally deliver large pieces of equipment. To maximize contiguous academic space on the second, third
and fourth floors of the building, the service area is placed in the basement level that also provides better
access to Craver Road.
Preliminary alternatives for the building found that it impacted the existing stream and caused the removal
of some existing large trees. This placement of the buildine was initially selected to attempt to balance the
earthwork. It was subsequently determined that by moving the buildine to the northwest that the stream
impacts would be reduced and a group of large trees would be saved. The trees would reduce solar gain of
the east side of the building. However, by moving the buildine to the current location there is a subsequent
increase of fill soil required.
Using the "Sustainable Site Planning Targets" recommended by the State, the University is working to
accomplish as many of these goals as possible. With this particular project UNCC is attempting to balance

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.
' 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

Describe impervious acreage (both existing and proposed) versus total acreage on the site.
' Discuss stormwater controls proposed in order to protect surface waters and wetlands
downstream from the property.
It is the Universities understanding that a Storm Water Management Plan is required when the impervious area
' exceeds 30% of the project area. The difficulty in determining this project area is that it is located in the middle of
the campus. There are limits that can be defined by physical boundaries adiacent to the site such as Cameron
Boulevard and Craver Road, existing buildings, parking and an area that is required for construction equipment to
operate safely. The latter is the approach used to calculate the Science and Technology project area. Surface runoff
will flow through grass swales and be collected into area drains on the east and south side of the building to assist in
sediment collection.
I Below are areas used to determine the need for a Storm Water Management Plan.
Project Area 6.5 acres
I Proposed Roof Area 1.0 acre
Proposed Brick Paving 0.34 acre
Proposed Service Drive 0.24 acre
Impervious area 24%
The followine reasons explain why it would be difficult to implement a Storm Water Management Plan.
1. The only level area adiacent to the building that could be utilized as a basin is near the intersection of
Cameron Boulevard and Craver Road. This area is remote from most of the drainage systems and would
be difficult to drain to.
2. The other level area that could be utilized for a wet basin exists on the west side of Cameron Boulevard.
This area is within a Reeulated Floodalain (see Attachment B - Exhibit 2). Toby Creek has flooded this
area of campus within the last few years several times. It would seem that the purpose of a system to
retain 85% of suspended solids would be ieopardized if it were installed in this area.

XII. Sewage Disposal (DWQOnly)
' Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
The UNCC campus is connected to the Charlotte Mecklenbure Utilities sanitary sewer service.
X1II. Violations (DWQ Only)
' Is this site in violation of DWQ Wetland Rules (15A NCAC 2H.0500) or any Buffer Rules?
Yes ? No
' Is this an after-the-fact permit application?
Yes ? No
' XIV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
' work schedules (e.g., draw-down schedules. for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
