Dear Mr. Domey:
I have enclosed 2 copies of a Storm Water Management Plan for Wilmore Walk LID. We have the 401
certification that was approved 4-16-03 and are now moving toward construction. The 401 application
document that was sent to your office contained a high level of detail concerning the storm water
management practices that are being employed onsite. This project is also a water quality pilot project
for the City of Charlotte Storm Water Services. The quantity of DWQ approved BMP's exceed the
amount required for this projects 401 certification. This project also incorporates an experimental
permeable concrete parking area that utilizes infiltration. Three of the approved bio-retention areas and
the permeable concrete / infiltration parking area will be funded and monitored by the City of Charlotte.
The Storm Water Management Plan describes in more detail the points of BMP design in concert with
the published NCDEHNR BMP Manual document.
If you have any questions please contact me at [phone].

Wilmore Walk Storm Water 11.9anagement Plan
City of Charlotte
Mecklenburg County, NC October 17, 2003
Approval of 401 Water Quality Certification With Additional
Comments
Approval of the subject application dated April 16, 2003, DWQ # 03-0190 was
received and additional conditions accepted. This document addresses additional
condition #3. Included in this document are final plans and specifications for
storm water management facilities that are appropriate for surface waters
classified as Class C and designed to remove 85% TSS according to the most
recent version of the NC DEHNR Storm Water Best Management Practices
Manual.
Introduction
The 2.84 -acre site is currently zoned for multi-family residential located within
the City of Charlotte, Mecklenburg County, North Carolina. The existing land-
use in the vicinity is single-family and commercial.
In order to enhance water quality and reduce storm water impacts to the existing
streams and in accordance with General Certification 3402, onsite bio-retention will
be implemented per to the most recent version of the NC DEHNR Storm Water Best
Management Practices Manual. Of the total 2.84 acres 0.56 (0.49 ac impervious) was
previously developed prior to 1987 as multi-family. The remaining 2.28 acres (1.44 ac
impervious) is treated through bio-retention. An additional 0.51 acres (0.074 ac
impervious) of off-site drainage will also be treated through bio-retention making the
total area treated through bio-retention 2.4 acres (2.004 ac impervious).
An additional 0.55 acres (0.22 ac impervious) will also be treated through an optional
Charlotte Storm Water Services infiltration pilot study using permeable concrete. The
location of the permeable concrete infiltration basin was chosen based on layout and
existing soils and geotechnical data for the site.
Sizing of the Bioretention Areas
A total of eight (8) bio-retention areas were sized according to the NC DEHNR Storm
Water BMP Manual. The minimum size of 15'x40' (600 sq. ft.) was used for seven (7)
of the eight (8) bio-retention areas. Bio-retention area "62" exceeds the minimum size
at 20'x44' (880 sq. ft.). The remaining (7) bio-retention area sizes vary from 111 sq.
ft. to 595 sq.ft. Preliminary areas were first calculated by multiplying 5% of the
contributing drainage area by the Rational Method "C" coefficient. This was then
refined using the SCS method RIO (Runoff in)=(P-0.2S)^2/(P+0.8S) with a 6-9"
ponding depth. A 9" ponding depth was used for BMP B2 & B3 with a 6" ponding
depth used for the rest.
The planting soil depth for all bio-retention areas is four feet (4')
Seven (7) of the eight (8) bio-retention drainage areas are less than half an acre with
the largest being 0.50 acres.
Drainage Considerations & Locating The Bioretention area
Drainage considerations that include the capture of sheet flow and potential erosion
were part of the placement equation when deciding where to locate each BMP. Since
all of the BMPS were retrofitted into an existing layout, conveyance calculations could
be tested by manipulating the existing grading plan to maximize sheet flow and
partitioning of each associated drainage area. Curb cuts will be used to capture

City of Charlotte
Mecklenburg County, NC October 17, 2003
parking area runoff while swales and sloped lawn areas convey runoff to four of the
eight (8) BMPS. A combination of vegetation and river stone will used in areas of
potential erosion at inlets and outlets.
Peak Runoff Control and Pollutant Reduction & Water Balance
The storage capacity of six out of eight bio-retention areas exceed the 1" or first flush
goals. Storage capacities for A1,A3,B1,B3 and B5 vary from 1.3" to 1.65" of run-off.
This adds a significant detention benefit as well as water quality treatment. Please
see the attached storm water run off and water balance spreadsheet in Exhibit 5.
The permeable concrete BMP stores and infiltrates the first 1" of runoff for it's
respective drainage basin with a calculated infiltration rate of .39 in/hr. The infiltration
rate was calculated using Green-Ampt equation for sandy loam. The geotechnical
report that was compiled from onsite borings was used when choosing the soil input
for the Green-Ampt equation used in the permeable concrete design.
Grading Plan
As previously mentioned, the basic grading plan was completed before the LID
analysis was initiated. Given the constraints of the site, the preliminary storm water
design and the development layout, the final grading plan was produced by slight
modifications respective of the new BMP layout.
Planting Plan& Plant Materials
The planting plan was designed with the site aesthetics, orientation, uses,
maintenance and water quality in mind. Given the relatively small sizes of the
bioretention areas, a minimum number of large maturing trees were used. The
landscape plan focuses primarily on small trees, shrubs and ground cover. See
Exhibit 6 or the proposed planting schedule.
Planting Soil& Mulch Layer
Planting soil shall be sandy loam as specified in the NCDEHNR Storm Water Best
Management Practices manual.
A 2"-3" mulch layer will be installed over the planting soil. Mulches specified in the
NCDEHNR Storm Water Best Management Practices manual will be used.
Maintenance & Monitoring
The City of Charlotte Storm Water Services have entered into a development
agreement to monitor three of the bio-retention sites and the pervious concrete
infiltration basin. The City will be monitoring these Bump's as part of a pilot study.
The pervious concrete specifications include a special provision for monitoring for a
minimum of four years. Three bio-retention areas will also be monitored by the City.
The City will set the frequency that all parameters are tested as outlined in the
NCDEHNR Storm Water Best Management Practices manual. At the end of the
monitoring period all bio-retention areas will be tested for toxicity and soil replaced as
necessary.
Maintenance of the pervious concrete will be a minimum of one vacuumed removal of
surface residue every year. Bioretention areas will be maintained by the Home

Comments:
The applicant is imposing to im a? ct up to 450 linear feet of jurisdictional ch annel for the purposes of
constructing a multi-family residential development. The total impacts includ e 80 linear feet of
channel with important aquatic values and 370 linear feet of channel with no aquatic value. Most of
the flow_ in the intermittent channel was subterranean except for a small port ion at the channel's
outlet, The majority of the channel has been severely degraded and channe lized in the past. The
channel is also heavily impacted by SW from off-site sources. The impacts will occur primarily as a
result of the extension of West Worthington Avenue, which will eventually b isect the site and make
the proposed channel impacts unavoidable- A site visit was conducted on O ctober 3, 2002 by the
writer, along with the applicant's consultant (Mr. Chris Estes), The applican t is proposing to use
hio-retention as SW management for the site-which will have to be approved by the Central Office
prior to 401 issuance. Pending approval of the applicant's SW managemen t plan, issuance of the
401 Gertification is recommended.

APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Ms. Mitchell:
You have our approval, in accordance with the attached conditions, to place permanent fill in 80 linear feet of perennial streams and
370 linear feet of intermittent streams in order to construct the Wilmore Walk subdivision in Mecklenburg County, as described in your
application received by the Division of Water Quality on February 19, 2003, and in additional correspondence received March 26, 2003.
After reviewing your application, we have determined that this fill is covered by General Water Quality Certification Number 3402, which
can be viewed on our web site at http://h2o.enr.state.nc.us/ncwetlands. This Certification allows you to use Nationwide Permit Number 39
when it is issued by the U.S. Army Corps of Engineers. 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, Non-Discharge and Water Supply Watershed
regulations. Also this approval will expire when the accompanying 404 permit expires unless otherwise specified in the General
Certification. This Certification replaces the one issued to you on April 3, 2003.
This approval is only valid for the purpose and design that you described in your application. If you change your project, you must
notify us in writing and you may be required to send us a new application for a new certification. If the property is sold, the new owner
must be given a copy of the 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). For this approval to be valid, you must follow the conditions listed in the attached certification, as well as the additional condition
listed below:
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or areas within
50 feet of all streams and ponds on the property. 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). A sample deed notification format can be downloaded from the 401/Wetiands Unit
web site at http://h2o.enr.state.nc.us/ncwetlands ;
2. An additional condition 4s that a final, written stormwater management plan shall be approved in writing by this Office before the
impacts specified in this Certification occur per condition no. 3 in General Certification 3402. The stormwater management plan must
include plans and specifications for stormwater management facilities that are'appropriate for surfac© waters classified as Class C
and deigned to remove 85% TSS according to the most recent version of the NC DENR Stormwater Best Management Practices
Manual. These facilities must be designed to treat the runoff from the entire project, unless otherwise explicitly approved by the
Division of Water Quality. 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. The
structural stormwater practices as approved by this Office as well as drainage patterns must be maintained in perpetuity. No changes
to the structural stormwater practices shall be made without written authorization from the Division of Water Quality;
3. You are required to return the attached Certification of Completion form to notify DWQ when all work included in the 401 Certification
has been completed.
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, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its
conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have any
questions, please telephone Mike Parker in our Mooresville Regional Office at 704-663-1699 or Cyndi Karoly in the Central Office in
Raleigh 919-733-9721.

DWQ Project No. 0.3019D
Mecklenburg County` 3^ ?'
The Division of Water Quality has reviewed your submittal for a 401 Water Quality Certification for the subject project.
Your application was not complete since you did not accurately provide the length of stream proposed for impact in your
application. Other information is also required. Specifically:
1) The application did not report all of the stream impacts proposed. Please revise the application to reflect all of the
stream to be impacted. Failure to accurately report impacts could result in your application being returned as
incomplete, denial of your application, or revocation of a 401 Water Quality Certification if issued based on inaccurate
reporting of impacts.
2) Please provide the following:
(a) The existing, on site impervious area not currently being treated by a stormwater BMP. _
(b) The total proposed on site impervious. area proposed (new,plus existing).
(c) The total on site impervious area to be treated by bioretention areas.
(d) The total off site impervious area to be treated by bioretention.
3) Mitigation may be required based on the fact that proposed stream impacts appear to be over 150 feet: -
This information is needed by the Division in order for us to decide whether this project is approvable.
Please call Todd St. John at 919-733-9584 if you have any questions. Until this information is received, I will place this
project on hold due to incomplete information (15A NCAC 2H .0507(a)).

Attach a vicinity map clearly showing the location of the property with respect to local landmarks such as
towns, rivers, and roads. Also provide a detailed site plan showing property boundaries and development
plans in relation to surrounding properties. Both the vicinity map and site plan must include a scale and
north arrow. The specific footprints of all buildings, impervious surfaces, or other facilities must be
included. If possible, the maps and plans should include the appropriate USGS Topographic Quad Map
and NRCS Soil Survey with the property boundaries outlined. Plan drawings, or other maps may be
included at the applicant's discretion, so long as the property is clearly defined. For administrative and
distribution purposes, the USACE requires information to be submitted on sheets no larger than 11 by 17-
inch format; however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are reduced to a
small scale such that the final version is illegible, the applicant will be informed that the project has been
placed on hold until decipherable maps are provided.

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 nronosed impact is unavoidable if the nronosed road is constructed in the existine road rieht-of-wav
and meets current City of Charlotte Design Standards. Currently, the existing road stub-outs are located at
either end of the subject open channel. Due to existing topography & surrounding development no other
route is feasible for the road. The proposed development is not feasible unless the road is constructed for
access in accordance with existing City Ordinances. All possible design scenarios have been considered
9
Wilmore Walk
City of Charlotte
Mecklenburg County, NC February 2, 2003
including partial road construction and alternate access routes. None of these scenarios are feasible due to
existing City codes and standards.
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 http://h2o.enr.state.nc.us/ncwetlands/strrngide.html.
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.
As per past discussions with Mr. Pete Colwell and NCDWQ no mitigation for stream impact is proposed.
However, since this project is within 1 mile of a 303d listed stream (Irvin Creek) Storm Water controls
are required to mitigate for water quality. To satisfy the storm water requirements Bio-Retention is being
proposed for this site in accordance with the NCDEHNR Stonn Water Best Management Practices
manual. The total area of bio-retention proposed exceeds the required area by 23%. An additional .55
acres of treatment is feasible by implementing an optional infiltration design. Please see the attached bio-
retention plan and calculations and the optional infiltration calculations for more detail.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program
(NCWRP) with the NCWRP's written agreement. Check the box indicating that you would like to pay

into the NCWRP. Please note that payment into the NCWRP must be reviewed and approved before it
can be used to satisfy mitigation requirements. Applicants will be notified early in the review process by
the 401/Wetlands Unit if payment into the NCWRP is available as an option. For additional information
regarding the application process for the NCWRP, check the NCWRP website at
http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCWRP is proposed, please check the appropriate box on

Jurisdictional Determination Site Visit
15
Pete Colwell visited the site with Len Rindner and Steve Chapin on
February 12, 2002. During that meeting Mr. Pete Colwell noted that he
would not require mitigation for the stream impacts but would require
storm water treatment and possible water quality improvement on site or
downstream. On October 3, 2002, Mr. Mike Parker and Mr. Chris Estes
met at the proposed Wilmore Walk site. The stream in question is a
straightened trapezoid shaped urban stream approximately 2'-3' wide at
the bottom and 3' deep that has been rip-rapped to the top of banks.
There had been rain within the past 24 hours. Most of the flow was
subterranean except for 15' at the pipe outfall and 65' above the subject
pipe inlet.
Introduction
The 2.84 -acre site is currently zoned for multi-family residential located
within the City of Charlotte, Mecklenburg County, North Carolina.
Approximately .75 acres are currently developed as apartments. This
property will be re-developed and incorporated into the overall project.
The existing land-use in the vicinity is single-family and commercial.
There is approximately 260 linear feet of degraded channel with little
aquatic function on the project site. All of which is located within an
existing road right -of-way. There is approximately 80 linear feet of
stream with important aquatic function.
Jurisdictional waters of the U.S.
Means and methods
Preliminary investigation of jurisdictional waters of the U.S. onsite was
done according to the U.S. Army Corps of Engineers technical report Y-
8 7-1 and Appendices, Corps of Engineers Wetlands Delineation
Manual, January 1987, Final Report. Additional data was acquired using
the U.S.G.S. quadrangle maps; the applicants survey plans, and the
applicants proposed grading plan, USDA soil survey of Mecklenburq
County North Carolina, aerial photographs and site visits. The
preliminary method of choice for wetland delineation was the level three
Routine Determination. The site is within the Lower Catawba drainage
basin. The majority of site is moderately sloping forested land.
Vegetation
The forested areas are dominated by FACW and FAC species. Trees
include Red oak, Hickory, tulip polar, green ash, cottonwood, red maple
and sweet gum. Under story and herbaceous strata include privet, alder
and smilax.
Hydric soils
The site includes Cecil-Urban (CuD) soils. The soils are mapped units
on broad ridges and slopes, which consist of well-drained, moderately
permeable soils with medium water capacity. High water table is greater
than 6', permeability is .60-2.0 in/hr and PH is 4.5-5.5, according to the
natural resource conservation service Soil Survey of Mecklenburg
County, issued January 1977.

Topography & Hydrofogy
The over all topography of the 2.84 acre project site is in it's self, a
contained drainage basin. The site drains to the center of the property.
The existing channel equally bisects the property. The channel reach
runs between two road stub outs. The channel completely contained
within the road right of way.

Preliminary planning for impact avoidance, minimization
and mitigation
Consideration for environmental and regulatory issues was incorporated into
the design process to minimize impacts to the extent feasible. Temporary
construction impacts due to clearing and grading activities will be the most
disruptive impact for this site. Therefore the following avoidance and
minimization practices will be taken:
1) Silt fence & barriers, sediment traps, check dams and diversion ditches.
2) Construction barricades to define construction limits and tree protection fence for
tree save areas.
3) Pre-construction meetings to inform equipment operators of sensitive areas and
precautionary practices.
4) Restriction of vehicular access to sensitive areas that are to be preserved.
5) Regular and frequent inspection of erosion control and access control practices.
6) Delineated wetland boundaries will be clearly marked prior to construction to
prevent accidental damage to wetlands and tree save areas. Contractors are liable for
unauthorized wetland and tree damage not authorized by this permit, specifications
and plans. If necessary pre-construction meetings will be held in the presence of
USACE and NCDWQ officials
7) Project construction will strictly adhere to an approved "Sedimentation and
Erosion Control Plan". Best Management Practices will include utilizing silt-
trapping ponds and other erosion control practices where appropriate. At no time
shall staging areas for equipment and supplies such as fuel be located near surface
waters or the delineated wetland areas.
8) As required by the 401 Water Quality Certification conditions, measures will be
taken to prevent "live concrete from coming into contact with waters until the
concrete has hardened.

Stream mitigation & storm water management
17
Stream Mitigation
The majority of the existing channel proposed to be impacted has no visible
flow and is subterranean. The open channel has become a dumping ground
for local residents and problematic source of sanitary sewer manhole
overflows. Where the open channel begins there is approximately 15 linear
feet of rip-rapped channel that contains a pool. Above this point it is
culverted beneath the existing road. Above the road there is approximately
120 feet of stream that emerges from an extensive culvert system that drains
South Blvd. and the adjacent mixed-use property (approx. 18 acres)
including residential, commercial and some industrial. The down stream end
of the dry channel enters back into an extensive culvert system that spans
approximately a mile. Due to the existing condition of the channel, the up and
down stream configuration, the existing pollutant collection and subsequent
discharge, it was determined previously by DWQ personnel that no stream
mitigation is necessary for this project.
Storm Water Management
In an effort to enhance water quality and reduce storm water impacts to the
existing streams, it is proposed that onsite bio-retention be implemented. Of
the total 2.84 acres 0.56 acres was previously developed multi-family with a
73% impervious surface. The remaining 2.28 acres will be treated through
bio-retention. An additional 0.51 acres of off-site drainage will also be treated
making the total area treated through bio-retention 2.4 acres. Please see the
attached calculations spread sheet.
The NCDEHR Storm Water Best Management Practices manual was used to
determine the bio-retention designs and will be included in the construction
documents.
An additional 0.55 acres is also available as an optional storm water
infiltration pilot study using permeable paving. This has been presented as a
partnering opportunity with Charlotte Storm Water Services.
Threatened and endangered species
Federally listed plant and animal species with endangered or threatened
status are protected under the Endangered Species Act of 1973. The U.S.
Fish and Wildlife Service have identified one endangered species
Schweinitz's sunflower (Helianthus schweinitzii). Schweinitz's sunflower is
endemic to the piedmont of the Carolinas, where it is currently known from
10 populations in North Carolina and 6 in South Carolina. The North Carolina
populations are located in Gaston, Anson, Montgomery, Davidson,
Randolph, Union, Stanly, Cabarrus, Mecklenburg, and Rowan Counties.
Schweinitz's sunflower usually grows in open habitat, contrary to the
character of the forested canopy habitat of this project site. None of the
Threatened, Endangered or Species of Concern was observed on site.
Notification has been made to and concurrence received from the U.S. Fish
and Wildlife (USFW).

Cultural resources
The project site is partially forested with some older development, indicating
it may have been left to succeed due the difficult terrain not conducive to
easy development. The surrounding land use is currently commercial, single
and multi-family residential. Notification has been made to and concurrence
received from the State Historic Preservation Office (SHPO).
Aquatic habitat
Aquatic systems on this project site are very limited and isolated from any
interaction with up stream or down stream systems.
Conclusion
The 2.84 acre development will provide important economic and social
benefits to the region. Impacts to the aquatic environment are minimal due to
the limited and low quality aquatic environment. By giving careful
consideration to construction and post development impacts, the contributing
water quality and community will be enhanced through public education on
bio-retention and sensitive management and maintenance of the bio-
retention areas in perpetuity.
Please don't hesitate to contact me if you have any questions regarding this
permit. My office phone number is [phone].

infiltration design will include a storage capacity greater than required to
store the first one-inch of rainfall. The permeable paving above the storage
reservoir will provide an infiltration rate 4 times faster than sand. The
proposed design is an option for additional water quality and retention
benefits.

Mr. Bill Gartland L
Crosland Land Company
141 Scaleybark Road
Charlotte, NC, 28209
APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Gartland:
You have our approval, in accords ched conditions, to place permanent fill ir(0.47 acre wetlands in order to
construct a residential subdivisj Threatt Beav tract in Mecklenburg County, as described*t-yoidr application received by the
Division of Water Quality on Janua 22, er reviewing your application, we have determined that this fill is covered by General
Water Quality Certification Number 336Z,-W-- hich can be viewed on our web site at http://h2o.enr.state.nc.us/ncwetlands. This Certification
allows you to use Nationwide Permit Number 39 when it is issued by the U.S. Army Corps of Engineers. 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,
Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the accompanying 404 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. If you change your project, you must
notify us in writing and you may be required to send us a new application for a new certification. If the property is sold, the new owner
must be given a copy of the 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). For this approval to be valid, you must follow the conditions listed in the attached certification, as well as the additional condition
listed below:
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or areas within
50 feet of all streams and ponds on the property. 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). A sample deed notification format can be downloaded from the 401/Wetlands Unit
web site at http://h2o.enr.state.nc.us/ncwetlands ;
2. An additional condition is that a final, written stormwater management plan shall be approved in writing by this Office before the
impacts specified in this Certification occur per condition no. 3 in General Certification 3402. The stormwater management plan must
include plans and specifications for stormwater management facilities that are appropriate for surface waters classified as Class C
and deigned to remove 85% TSS according to the most recent version of the NC DENR Starmwater Best Management Practices
Manual. These facilities must be designed to treat the runoff from the entire project, unless otherwise explicitly approved by the
Division of Water Quality. 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. The
structural stormwater practices as approved by this Office as well as drainage patterns must be maintained in perpetuity. No changes
to the structural stormwater practices shall be made without written authorization from the Division of Water Quality;
3. You are required to return the attached Certification of Completion form to notify DWQ when all work included in the 401 Certification
has been completed.
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, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its
conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have any
questions, please telephone Mike Parker in our Mooresville Regional Office at 704-663-1699 or Cyndi Karoly in the Central Office in
Raleigh 919-733-9721.

This form is to be used for projects qualifying for any of the U.S. Army Corps of Engineers' (USACE)
Nationwide, Regional or General Permits as required by Section 404 of the Clean Water Act and/or
Section 10 of the Rivers and Harbors Act, and for the North Carolina Division of Water Quality's (DWQ)
associated General 401 Water Quality Certifications. This form is also to be used for any project
requiring approval under any Riparian Buffer Rules implemented by the N.C. Division of Water Quality.
This form should not be used if you are requesting an Individual 404 Permit or Individual 401 Water
Quality Certification. The USACE Individual Permit application form is available online at
http://wwxv.saw.usace.army.mil/wetlands/Perm app htm.
The USACE is the lead regulatory agency. To review the requirements for the use of Nationwide,
Regional or General permits, and to determine which permit applies to your project, please go to the
USACE website at http://www.saw.usace.army.mi]/wet]ands/regtour.htm, or contact one of the field
offices listed at the end of this application. The website also lists the responsible project manager for each
county in North Carolina and provides additional information regarding the identification and regulation
of wetlands and waters of the U.S.
The DWQ issues a corresponding Certification (General or Individual), and cannot tell the applicant
which 401 Certification will apply until the 404 Permit type has been detennined by the USACE.
Applicants are encouraged to visit DWQ's 401/Wetlands Unit website at
http://h2o.enr.state.nc.us/ncwetlands to read about current requirements for the 401 Water Quality
Certification Program and to detennine whether or not Riparian Buffer Rules are applicable. The
applicant is also advised to read the full text of the General Certification (GC) matching the specific 404
Permit requested. In some cases, written approval for some General Certifications is not required,
February 2, 2003
Wilmore Walk 3

regional coordinator (listed by county on the last page of this application).
CAMA Coordination - If the project occurs in any of North Carolina's twenty coastal counties (listed on the last page
of this application) the applicant should also contact the North Carolina Division of Coastal Management (DCM) at
[phone]. DCM will determine whether or not the project involves a designated Area of Environmental
Concern, in which case DCM will act as the lead permitting agency. In such cases, DCM will require a Coastal Area
Management Act (CAMA) Permit and will coordinate the 404/401 Permits.
USACE Permits - Submit one copy of this form, along with supporting narratives, maps, data forms,
photos, etc. to the applicable USACE Regulatory Field Office (addresses are listed at the end of this
application). Upon receipt of an application, the USACE will determine if the application is complete as

to address information needs for all USACE Nationwide, Regional or General permits, as well as
information required for State authorizations, certifications, and coordination. Fully providing the
information requested on this form will result in a complete application for any of the USACE
Nationwide, Regional or General permits. To review the minimum amount of information that must be
provided for a complete PCN for each USACE Nationwide permit, see Condition 13, 65 Fed.Reg. 12893

401 Water Quality Certification or Buffer Rules - All information is required unless otherwise stated as
optional. Incomplete applications will be returned. Submit seven collated copies of all USACE Permit
materials to the Division of Water Quality, 401/Wetlands Unit, 1650 Mail Service Center, Raleigh, NC,
27699-1650. If written approval is required or specifically requested for a 401 Certification, then a non-
refundable application fee is required. In brief, if project impacts include less than one acre of cumulative
wetland/water impacts and less than 150 feet cumulative impacts to streams, then a fee of $200 is
required. If either of these thresholds is exceeded, then a fee of $475 is required. A check made out to the
North Carolina Division of Water Quality, with the specific name of the project or applicant identified,
should be stapled to the front of the application package. For more information, see the DWQ website at
http://h2o.ehnr.state.nc.us/ncwet]ands/fees.htmi. The fee must be attached with the application unless the
applicant is a federal agency in which case the check may be issued from a separate office. In such cases,
the project must be identifiable on the U.S. Treasury check so that it can be credited to the appropriate
project. If written approval is sought solely for Buffer Rules, the application fee does not apply, and the
applicant should clearly state (in a cover letter) that only Buffer Rule approval is sought in writing.
Wetlands or waters of the U.S. may not be impacted prior to issuance or waiver of a Section 401 Water
Quality Certification. Upon receipt of a complete application for a 401 Certification, the Division of Water
Quality has 60 days to prepare a written response to the applicant. This may include a 401 Certification,
an on-hold letter pending receipt of additional requested information, or denial.

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 impact is unavoidable if the proposed road is constructed in the existing road riuht-of-wav
and meets current City of Charlotte Design Standards. Currently, the existing road stub-outs are located at
either end of the subject open channel Due to existing topography & surrounding development no other
route is feasible for the road. The proposed development is not feasible unless the road is constructed for
access in accordance with existing City Ordinances All possible design scenarios have been considered

including partial road construction and alternate access routes None of these scenarios are feasible within
existing Citv codes and standards.
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 http://h2o.enr.state.nc.us/ncwetlands/strmgide.html.
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.
As per past discussions with Mr. Pete Colwell and NCDWQ no mitigation for stream impact is proposed
During the growing season 370' of channel has no visible flow and only flows during storm events This
370' is classified as intermittent unimportant. This 370' section is a rip-rapped trapezoid channel that is
severely degraded by urban debris and sediment At the high point of the intermittent reach is a plunge
pool approximately 15' in length which begins at a 36' culvert outlet This plunge pool is classified as
important. Upstream from the plunge pool is 165' of culvert which davlights to 65' of stream that is
classified as perennial. Since this project is within 1 mile of a 303d listed stream (Irwin Creek) Storm
Water controls are required to mitigate for water quality. To satisfy the storm water requirements Bio-
Retention is being proposed for this site in accordance with the NCDEHNR Storm Water Best
Management Practices manual. The total area of bio-retention proposed exceeds the amount required
calculated by watershed area by 23%. An additional 24 acres of treatment will be implemented as an
optional infiltration design. This will be implemented as a Charlotte Storm Water Services Pilot BMP
Study in order to learn more about Permeable Pavement use in Piedmont Sandy Clay soils Please see
pages 24 & 25 for bio-retention plan, calculations and the optional infiltration layout and
calculations for more detail.

Jurisdictional Determination Site Visit
Pete Colwell visited the site with Len Rindner and Steve Chapin on
February 12, 2002. During that meeting Mr. Pete Colwell noted that he
would not require mitigation for the stream impacts but would require
storm water treatment and possible water quality improvement on site or
downstream. On October 3, 2002, Mr. Mike Parker and Mr. Chris Estes
met at the proposed Wilmore Walk site. The stream in question is a
straightened trapezoid shaped urban stream approximately 2'-3' wide at
the bottom and 3' deep that has been rip-rapped to the top of banks.
There had been rain within the past 24 hours. Most of the flow was
subterranean except for 15' at the pipe outfall and 65' above the subject
pipe inlet.
Introduction
The 2.84 -acre site is currently zoned for multi-family residential located
within the City of Charlotte, Mecklenburg County, North Carolina.
Approximately .56 acres previously developed as apartments. This
property is proposed to be re-developed and incorporated into the overall
project. The existing land-use in the vicinity is single-family and
commercial. There is approximately 370 linear feet of degraded channel
with little aquatic function on the project site. All of which is located within
an existing road right -of-way. There is approximately 80 linear feet of
stream with important aquatic function.
Jurisdictional waters of the U.S.
Means and methods
Preliminary investigation of jurisdictional waters of the U.S. onsite was
done according to the U.S. Army Corps of Engineers technical report Y-
8 7- 1 and Appendices, Corps of Engineers Wetlands Delineation
Manual, January 1987, Final Report. Additional data was acquired using
the U.S.G.S. quadrangle maps; the applicants survey plans, and the
applicants proposed grading plan, USDA soil survey of Mecklenburg
County North Carolina, aerial photographs and site visits. The
preliminary method of choice for wetland delineation was the level three
Routine Determination. The site is within the Lower Catawba drainage
basin. The majority of site is moderately sloping forested land.
Vegetation
The forested areas are dominated by FACW and FAC species. Trees
include Red oak, Hickory, tulip polar, green ash, cottonwood, red maple
and sweet gum. Under story and herbaceous strata include privet, alder
and smilax.
Hydric soils
The site includes Cecil-Urban (CuD) soils. The soils are mapped units
on broad ridges and slopes, which consist of well-drained, moderately
permeable soils with medium water capacity. High water table is greater
than 6', permeability is .60-2.0 in/hr and PH is 4.5-5.5, according to the
natural resource conservation service Soil Survey of Mecklenburg
County, issued January 1977.

Topography & Hydrology
The over all topography of the 2.84 acre project site is in it's self, a
contained drainage basin. The site drains to the center of the property.
The existing channel equally bisects the property. The channel reach
runs between two road stub outs. The channel completely contained

Preliminary planning for impact avoidance, minimization
and mitigation
Consideration for environmental and regulatory issues was incorporated into
the design process to minimize impacts to the extent feasible. Temporary
construction impacts due to clearing and grading activities will be the most
disruptive impact for this site. Therefore the following avoidance and
minimization practices will be taken:
1) Silt fence & barriers, sediment traps, check dams and diversion ditches.
2) Construction barricades to define construction limits and tree protection fence for
tree save areas.
3) Pre-construction meetings to inform equipment operators of sensitive areas and
precautionary practices.
4) Restriction of vehicular access to sensitive areas that are to be preserved.
5) Regular and frequent inspection of erosion control and access control practices.
6) Delineated wetland boundaries will be clearly marked prior to construction to
prevent accidental damage to wetlands and tree save areas. Contractors are liable for
unauthorized wetland and tree damage not authorized by this permit, specifications
and plans. If necessary pre-construction meetings will be held in the presence of
USACE and NCDWQ officials
7) Project construction will strictly adhere to an approved "Sedimentation and
Erosion Control Plan". Best Management Practices will include utilizing silt-
trapping ponds and other erosion control practices where appropriate. At no time
shall staging areas for equipment and supplies such as fuel be located near surface
waters or the delineated wetland areas.

8) As required by the 401 Water Quality Certification conditions, measures will be
taken to prevent "live concrete from coming into contact with waters until the
concrete has hardened.
Stream mitigation $ storm water management
Stream Mitigation
The majority (370') of the existing channel proposed to be impacted has no
visible flow and is subterranean. The open channel has become a dumping
ground for local residents and problematic source of sanitary sewer manhole
overflows. Where the open channel begins there is approximately 15 linear
feet of rip-rapped channel that contains a pool. Above this point it is
culverted beneath the existing road. Above the road there is approximately
120 feet of stream that emerges from an extensive culvert system that drains
South Blvd. and the adjacent mixed-use property (approx. 18 acres)
including residential, commercial and some industrial. Eighty feet (80') of this
is classified as important. The down stream end of the dry channel enters
back into an extensive culvert system that spans approximately a mile. Due
to the existing condition of the channel, the up and down stream
configuration, the existing pollutant collection and subsequent discharge, it
was determined previously by DWQ personnel that no stream mitigation is
necessary for this project.
Storm Water Management
In an effort to enhance water quality and reduce storm water impacts to the
existing streams, it is proposed that onsite bio-retention be implemented. Of
the total 2.84 acres 0.56 acres was previously developed multi-family with a
73% impervious surface. The remaining 2.28 acres will be treated through
bio-retention. An additional 0.51 acres of off-site drainage will also be treated
making the total area treated through bio-retention 2.4 acres. Please see the
attached calculations spread sheet on page 24 and 25.
The NCDEHR Storm Water Best Management Practices manual was used to
determine the bio-retention designs and will be included in the construction
documents.
An additional 0.55 acres is also available as an optional storm water
infiltration pilot study using permeable paving. This has been presented as a
partnering opportunity with Charlotte Storm Water Services.
Threatened and endangered species
Federally listed plant and animal species with endangered or threatened
status are protected under the Endangered Species Act of 1973. The U.S.
Fish and Wildlife Service have identified one endangered species
Schweinitz's sunflower (Helianthus schweinitzii). Schweinitz's sunflower is
endemic to the piedmont of the Carolinas, where it is currently known from
10 populations in North Carolina and 6 in South Carolina. The North Carolina
populations are located in Gaston, Anson, Montgomery, Davidson,
Randolph, Union, Stanly, Cabarrus, Mecklenburg, and Rowan Counties.
Schweinitz's sunflower usually grows in open habitat, contrary to the
character of the forested canopy habitat of this project site. None of the
Threatened, Endangered or Species of Concern was observed on site.
Notification has been made to and concurrence received from the U.S. Fish
and Wildlife (USFW).

The project site is partially forested with some older development, indicating
it may have been left to succeed due the difficult terrain not conducive to
easy development. The surrounding land use is currently commercial, single
and multi-family residential. Notification has been made to and concurrence
received from the State Historic Preservation Office (SHPO).
Aquatic habitat
Aquatic systems on this project site are very limited and isolated from any
interaction with up stream or down stream systems.
Conclusion
The 2.84 acre development will provide important economic and social
benefits to the region. Impacts to the aquatic environment are minimal due to
the limited and low quality aquatic environment. By giving careful
consideration to construction and post development impacts, the contributing
water quality and community will be enhanced through the removal of a
direct pollution charging area, public education on bio-retention and
permeable pavement and sensitive management and maintenance of the
bio-retention areas in perpetuity.
Please don't hesitate to contact me if you have any questions regarding this
permit. My office phone number is [phone].

The above calculations illustrate the ability of the existing soil to infiltrate 1" or
2.54 cm of rainfall. Above the existing soil profile, the proposed optional
infiltration design will include a storage capacity greater than required to
store the first one-inch of rainfall. The permeable paving above the storage
reservoir will provide an infiltration rate 4 times faster than sand. The
proposed design is an option for additional water quality and retention
benefits.

Minimum Guide Specification for Dewaterini!

NOTE: The following specifications are for use as a guide for development of actual specifications.
The guide is not intended for use as a construction specification without modifications to reflect
specific project conditions.

Control of ground water shall be accomplished in a manner that will preserve the strength of the
foundation soils, will not cause instability of the excavation slopes, and will not result in damage to
existing structures. Where necessary to these purposes, the water level shall be lowered in advance
of excavation, utilizing wells, well points, or similar methods. The water level, as measured in
piezometers, shall be maintained a minimum of three feet below the prevailing excavation level.
Open pumping with sumps and ditches, if it results in boils, loss of fines, softening of the ground or
instability of slopes, will not be permitted. Wells and well points shall be installed with suitable
screens and filters so that continuous pumping of fines does not occur. The discharge shall be
arranged to facilitate collection of samples by the Engineer.

Impact Justification (.voidance 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 nronosed imnact is unavoidable if the nronosed road is constructed in the existiiw road riL*ht-of-wav
and meets current City of Charlotte Design Standards. Currently, the existing road stub-outs are located at
either end of the subject open channel. Due to existint; tonotrranhy & surrounding development no other
route is feasible for the road. The proposed development is not feasible unless the road is constructed for
access in accordance with existing Citv Ordinances. All possible designs scenarios have been considered

including partial road construction and alternate access routes. None of these scenarios are feasible due to
existintz City codes and standards.
Mitigation
9
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
USAGE 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 littp://li2o.enr.state.nc.us/ncxvetlands%strinLld,.htinl.
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.
Asper past discussions with Mr. Pete Colwell and NCDWQ no mitiLation for stream impact is proposed.
However, since this project is within 1 mile of a 303d listed stream (Irwin Creek) Storm Water controls
are required to mitigate for water quality. To satisfy the storm water requirements Bio-Retention is being
proposed for this site in accordance with the NCDEHNR Storm Water Best Management Practices
manual. The total area of bio-retention proposed exceeds the required area by 231/0. An additional .55
acres of treatment is feasible by implementing an optional infiltration desitrn. Please see the attached NO-
retention plan and calculations and the optional infiltration calculations for more detail.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program
(NCWRP) with the NCWRP's written agreement. Check the box indicating that you would like to pay

Wilmore Wall;

into the NCWRP. Please note that payment into the NCWRP must be reviewed and approved before it
can be used to satisfy mitigation requirements. Applicants will be notified early in the review process by
the 401/Wetlands Unit if payment into the NCWRP is available as an option. For additional information
regarding the application process for the NCWRP, check the NCWRP website at

Jurisdictional Determination Site Visit
1.5
Pete Colwell visited the site with Len Rindner and Steve Chapin on
February 12, 2002. During that meeting Mr. Pete Colwell noted that he
would not require mitigation for the stream impacts but would require
storm water treatment and possible water quality improvement on site or
downstream. On October 3, 2002, Mr. Mike Parker and Mr. Chris Estes
met at the proposed Wilmore Walk site. The stream in question is a
straightened trapezoid shaped urban stream approximately 2'-3' wide at
the bottom and 3' deep that has been rip-rapped to the top of banks.
There had been rain within the past 24 hours. Most of the flow was
subterranean except for 15' at the pipe outfall and 65' above the subject
pipe inlet.
Introduction
The 2.84 -acre site is currently zoned for multi-family residential located
within the City of Charlotte, Mecklenburg County, North Carolina.
Approximately .75 acres are currently developed as apartments. This
property will be re-developed and incorporated into the overall project.
The existing land-use in the vicinity is single-family and commercial.
There is approximately 260 linear feet of degraded channel with little
aquatic function on the project site. All of which is located within an
existing road right -of-way. There is approximately 80 linear feet of
stream with important aquatic function.
Jurisdictional waters of the U.S.
means and methods
Preliminary investigation of jurisdictional waters of the U.S. onsite was
done according to the U.S. Army Corps of Engineers technical report Y-
8 7- 1 and Appendices, Corps of Engineers Wetlands Delineation
Manual, January 1987, Final Report. Additional data was acquired using
the U.S.G.S. quadrangle maps; the applicants survey plans, and the
applicants proposed grading plan, USDA soil survey of Mecklenburg
County North Carolina, aerial photographs and site visits. The
preliminary method of choice for wetland delineation was the level three
Routine Determination. The site is within the Lower Catawba drainage
basin. The majority of site is moderately sloping forested land.
Vegetation
The forested areas are dominated by FACW and FAC species. Trees
include Red oak, Hickory, tulip polar, green ash, cottonwood, red maple
and sweet gum. Under story and herbaceous strata include privet, alder
and smilax.
Hvdric soils
The site includes Cecil-Urban ((;uD) soils. The soils are mapped units
on broad ridges and slopes, which consist of well-drained, moderately
permeable soils with medium water capacity. High water table is greater
than 6', permeability is .60-2.0 in/hr and PH is 4.5-5.5, according to the
natural resource conservation service Soil Survey of Mecklenburg
County, issued January 1977.

Topography & Hydrology
The over all topography of the 2.84 acre project site is in it's self, a
contained drainage basin. The site drains to the center of the property.
The existing channel equally bisects the property. The channel reach
runs between two road stub outs. The channel completely contained
within the road right of way.

Preliminary planning for impact avoidance, minimization
and mitigation
Consideration for environmental and regulatory issues was incorporated into
the design process to minimize impacts to the extent feasible. Temporary
construction impacts due to clearing and grading activities will be the most
disruptive impact for this site. Therefore the following avoidance and
minimization practices will be taken:
I ) Silt fence & barriers, sediment traps, check dams and diversion ditches.
2) Construction barricades to define construction limits and tree protection fence for
tree save areas.
3) Pre-construction meetings to inform equipment operators of sensitive areas and
precautionary practices.
4) Restriction of vehicular access to sensitive areas that are to be preserved.
5) Regular and frequent inspection of erosion control and access control practices.
G) Delineated wetland boundaries will be clearly marked prior to construction to
prevent accidental damage to wetlands and tree save areas. Contractors are liable for
unauthorized wetland and tree damage not authorized by this permit, specifications
and plans. If necessary pre-construction meetings will be held in the presence of
USACE and NCDWQ officials
7) Project construction will strictly adhere to an approved "Sedimentation and
Erosion Control Plan". Best Management Practices will include utilizing silt-
trapping ponds and other erosion control practices where appropriate. At no time
shall staging areas for equipment and supplies such as fuel be located near surface
waters or the delineated wetland areas.
8) As required by the 401 Water Quality Certification conditions, measures will be
taken to prevent "live concrete from coming into contact with waters until the
concrete has hardened.

Stream mitigation & storm water management
17
Stream Mitigation
The majority of the existing channel proposed to be impacted has no visible
flow and is subterranean. The open channel has become a dumping ground
for local residents and problematic source of sanitary sewer manhole
overflows. Where the open channel begins there is approximately 15 linear
feet of rip-rapped channel that contains a pool. Above this point it is
culverted beneath the existing road. Above the road there is approximately
120 feet of stream that emerges from an extensive culvert system that drains
South Blvd. and the adjacent mixed-use property (approx. 18 acres)
including residential, commercial and some industrial. The down stream end
of the dry channel enters back into an extensive culvert system that spans
approximately a mile. Due to the existing condition of the channel, the up and
down stream configuration, the existing pollutant collection and subsequent
discharge, it was determined previously by DWQ personnel that no stream
mitigation is necessary for this project.
Storm Water Management
In an effort to enhance water quality and reduce storm water impacts to the
existing streams, it is proposed that onsite bio-retention be implemented. Of
the total 2.84 acres 0.56 acres was previously developed multi-family with a
73% impervious surface. The remaining 2.28 acres will be treated through
bio-retention. An additional 0.51 acres of off-site drainage will also be treated
making the total area treated through bio-retention 2.4 acres. Please see the
attached calculations spread sheet.
The NCDEHR Storm Water Best Management Practices manual was used to
determine the bio-retention designs and will be included in the construction
documents.
An additional 0.55 acres is also available as an optional storm water
infiltration pilot study using permeable paving. This has been presented as a
partnering opportunity with Charlotte Storm Water Services.
Threatened and endangered species
Federally listed plant and animal species with endangered or threatened
status are protected under the Endangered Species Act of 1973. The U.S.
Fish and Wildlife Service have identified one endangered species
Schweinitz's sunflower (Helianthus schweinitzii). Schweinitz's sunflower is
endemic to the piedmont of the Carolinas, where it is currently known from
10 populations in North Carolina and 6 in South Carolina. The North Carolina
populations are located in Gaston, Anson, Montgomery, Davidson,
Randolph, Union, Stanly, Cabarrus, Mecklenburg, and Rowan Counties.
Schweinitz's sunflower usually grows in open habitat, contrary to the
character of the forested canopy habitat of this project site. None of the
Threatened, Endangered or Species of Concern was observed on site.
Notification has been made to and concurrence received from the U.S. Fish
and Wildlife (USFW).

The project site is partially forested with some older development, indicating
it may have been left to succeed due the difficult terrain not conducive to
easy development. The surrounding land use is currently commercial, single
and multi-family residential. Notification has been made to and concurrence
received from the State Historic Preservation Office (SHPO).
Aquatic habitat
Aquatic systems on this project site are very limited and isolated from any
interaction with up stream or down stream systems.
Conclusion
The 2.84 acre development will provide important economic and social
benefits to the region. Impacts to the aquatic environment are minimal due to
the limited and low quality aquatic environment. By giving careful
consideration to construction and post development impacts, the contributing
water quality and community will be enhanced through public education on
bio-retention and sensitive management and maintenance of the bio-
retention areas in perpetuity.

permit. My office phone number is [phone].

The above calculations illustrate the ability of the existing soil to infiltrate V or
2.54 cm of rainfall. Above the existing soil profile, the proposed optional
infiltration design will include a storage capacity greater than required to
store the first one-inch of rainfall. The permeable paving above the storage
reservoir will provide an infiltration rate 4 times faster than sand. The
proposed design is an option for additional water quality and retention
benefits.
