WETLANDS AND STORMWATER BRANCH
On June 30, 2004, the NC Division of Water Quality (DWQ) received your application for a General 401
Water Quality Certification for the construction of the Brookdale development in Cabarrus County. On August
5, 2004, this office issued a letter informing you that DWQ would require mitigation for the stream impact at the
site. You were also informed that the project would be placed on hold until DWQ received notice from the
Ecosystem Enhancement Program (EEP) that payment for mitigation had been accepted, or that a mitigation
plan had been submitted and approved. To date no payment or mitigation plan has been received.
If we fail to hear from you within 15 days of receipt of this letter we will assume you no longer want to
pursue the project and will withdraw the application from consideration. If you have any questions, please
contact Mr. Alan Johnson at [phone] or Ms. Cyndi Karoly in Raleigh at [phone].

Dear Ms. Karoly:
This letter is to inform you that American Asset Corporation is withdrawing their request for a 401 Water
Quality Certification as described in the PCN application received in your office on June 30, 2004. Since
the time of that application, the site has been redesigned and proposed stream impacts have been reduced
from 296 linear feet to 145 linear feet. Therefore, we request that the previously submitted PCN
application be withdrawn from consideration. Included for your files is a Site Location Map showing the
project area and a Post-Development Site Layout prepared by Design Resource Group showing the
revised impact.
Please contact me at [phone] if you have questions or require additional information.

Dear Mr. Dye:
WETLANDS/ 401 GROUP
AUG 1 0 2004
WATER QUALITY SECTION
On June 30, 2004, the NC Division of Water Quality (DWQ) received your application for a General 401
Water Quality Certification for the construction of the Brookdale development in Cabarrus County.
On August 4, 2004, Mr. Alan Johnson with this office conducted a site inspection. During the
inspection of the stream at the site, Mr. Johnson observed an abundance of crayfish burrows along the
channel, as well as numerous crayfish. Based on his observations, the Division of Water Quality (DWQ) is
requiring mitigation for the proposed 296 linear feet of stream impacts.
You may choose to contribute to the Ecosystem Enhancement Program (EEP) fund to compensate for
the stream impact or seek approval for a mitigation plan of your own. Until the DWQ receives notice from
the EEP or an approved mitigation plan is accepted, this office is requesting (by copy of this letter) that the
Corps of Engineers place this project on hold. Also, this project will be placed on hold for our processing
pursuant to 15A NCAC 2H .0507(h).
If you have any questions, please contact Alan Johnson at [phone] or Cyndi Karoly in Raleigh
at [phone].

Dear Mr. Dorney:
WETLANDS/ 401 GROUP
JUN 3 0 2004
WATER QUALITY SECTION
Please find seven copies of the Pre-Construction Notification (PCN) application for the above referenced
site. The site is an approximate 17.48 acre tract located at the intersection of Rocky River Road and Plaza
Road in Harrisburg, North Carolina (Figure 1). The site is being evaluated for commercial development.
An unnamed tributary to Reedy Creek originates on the site as an intermittent/unimportant stream
channel. Approximately 296 linear feet of this unimportant channel will be impacted by the proposed
development.
As illustrated on the Site Layout an access road must be constructed into the site from Plaza Road. The
location of the access road has been determined by the N.C. DOT and cannot be moved. In addition,
commercial buildings and parking lots will be constructed on the site. The access road, buildings and
parking lots will impact approximately 296 liner feet of unimportant channel. The remainder of the
channel will be preserved.
The quality of the channel improves down stream of the impact area. The I/P point on the channel is
illustrated on the Site Layout prepared by Design Resource Group. The perennial/important portion of
the stream channel will be preserved and will not be filled or piped. In addition, appropriate erosion
control measures will be installed to protect the perennial/important portion of the stream channel. The
original site development plan involved piping the entire length of stream. In order to minimize impacts,
the site has been redesigned in order to preserve the majority of the stream. Since the portion of the
stream that will be piped is intermittent/unimportant, mitigation should not be required and none is
proposed.

M. Project Information
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.
1. Name of project: Brookdale
2. T.I.P. Project Number or State Project Number (NCDOT Only):
3. Property Identification Number (Tax PIN):
4. Location
County: Cabarrus Nearest Town: Harrisburg
Subdivision name (include phase/lot number): Brookdale
Directions to site (include road numbers, landmarks, etc.): I-85 to 485 South; east on Hwy
49; south on Robinson Church Road; west on Rocky River Road. The site is on the
south side of Rocky River Road at the Mecklenburg/Cabarrus County line.
5. Site coordinates, if available (UTM or Lat/Long):
(Note - If project is linear, such as a road or utility line, attach a sheet that separately lists the
coordinates for each crossing of a distinct waterbody.)
6. Property size (acres): 17.42 Acres
7. Nearest body of water (stream/river/sound/ocean/lake): UT to Reedy Creek
8. River Basin: Yadkin/PeeDee
(Note - this must be one of North Carolina's seventeen designated major river basins. The
River Basin map is available at http://h2o.enr.state.nc.us/admin/mn-/.)
9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The site is currently undeveloped. The surrounding
properties contain residential and commercial development.
Page 2 of 8
10. Describe the overall project in detail, including the type of equipment to be used: The
site is being prepared for commercial development. Trucks, pans, loaders, bulldozers,
etc. will be used during construction.
11. Explain the purpose of the proposed work: The purpose of the work is to construct a
commercial development on the site. When developed, the site will contain commercial
businesses and parking lots and driveways.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules.
There have been no previous permits requested or obtained for this project.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
We do not anticipate future permit requests for this project.
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, permanent
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must be shown on a
delineation map, whether or not impacts are proposed to these systems. Wetland and stream
evaluation and delineation forms should be included as appropriate. Photographs may be
included at the applicant's discretion. If this proposed impact is strictly for wetland or stream
mitigation, list and describe the impact in Section VIII below. If additional space is needed for
listing or description, please attach a separate sheet.
Page 3 of 8
Provide a written description of the proposed impacts: An access drive, commercial
buildings and parking lots will be constructed on the site. The location of the access
drive has been determined by the NCDOT. The access drive, buildings and parking
lots will impact approximately 296 linear feet of intermittentlunimportant stream
channel. The remainder of the stream channel will not be impacted by the
development.
2. Individually list wetland impacts below: There will be no wetland impacts associated with
this project.

* List each impact separately and identify temporary impacts. Impacts include, but are not limited to: culverts and associated rip-rap,
dams (separately list impacts due to both structure and flooding), relocation (include linear feet before and after, and net loss/gain),
stabilization activities (cement wall, rip-rap, crib wall, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is
proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included.
** Stream names can be found on USGS topographic maps. If a stream has no name, list as UT (unnamed tributary) to the nearest
downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at
www.usgs.gov. Several intemet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com,
ww,v.magquest.com, etc.).
Cumulative impacts (linear distance in feet) to all streams on site: Approximately 2961f

5. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): X uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): dam/embankment
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): Stormwater requirement.
Size of watershed draining to pond: 13 acres Expected pond surface area: A.3 acres
VII. 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.
An entrance drive from Plaza Road is required to access the site. The NCDOT has
determined the location of the entrance drive. The entrance drive will cross an
intermittent stream channel located near the eastern boundary of the site. In addition,
commercial buildings and parking lots will be constructed in this area. The entrance drive
and commercial buildings/parking lots will impact approximately 296 linear feet of
unimportant/intermittent stream channel. The quality of the stream channel improves
down stream of the impact area. The UP point on the channel is illustrated on the Site
Layout Prepared by Design Resource Group. The perennial/important portion of the
stream channel will be preserved and will not be filled or piped. In addition, appropriate
erosion control measures will be installed to protect the perennial/important portion of the
stream channel. The original site development plan involved piping the entire length of
stream. The site has been redesigned in order to preserve the maiority of the stream.

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
.
http://h2o.enr.state.nc.us/newetlands/strmgide.html
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
An intermittent/unimportant stream channel will be impacted by the development. Due
to the low quality of the stream, mitigation should not be required and none is
proposed
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.ne.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet):,
Amount of buffer mitigation requested (square feet):

X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify V
Yes ? No X If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.

FROM: Ron Linville, Regional Coordinator
Habitat Conservation Program
DATE: July 21, 2004
WETLANDS 1401 RCV- A

WATER MAl. i x Y,'?
SUBJECT: Review of an application by Brookdale Subdivision, Town of Harrisburg,
Unnamed Tributary Reedy Creek, DWQ 041072, Cabarrus County
The applicant is requesting 401 Water Quality Certification from the North Carolina
Division of Water Quality. The NCWRC has reviewed information provided by the
applicant, and field biologists on our staff are familiar with habitat values of the project
area. These comments are provided in accordance with provisions of the Clean Water
Act of 1977 (33 U.S.C. 466 et. seq.) and the Fish and Wildlife Coordination Act (48 Stat.
401, as amended; 16 U.S.C. 661-667d).
The project is the Brookdale Phase II development that appears to be a commercial
development. Impacts to an "unimportant/intermittent stream" are indicated to be + 296
linear feet of channel. Site development on the site is indicated to be approximately 85%.
Based on our review of the site layout, it appears that impacts to the channel will be for
an access drive, parking lot and building. This same drawing shows that a stormwater
pond is planned next to the perennial stream just below the impacted intermittent channel.
The historical range of the Carolina heelsplitter (Lasmigona decorata), a federal and state
listed endangered species is present in the area. This species is believed to be extirpated
from the area. The Carolina creekshell (Villosa vaughniana), a federal species of concern
and state endangered species is known in area watersheds. The Carolina fatmucket
(Lamsilis radiata conspicua), a state threatened species and the Carolina darter
(Etheostoma collis) a state and federal species of concern is known for the area as well.
We are concerned about lost headwaters, natural stream buffers and intermittent channels
that help absorb or assimilate stormwater. Sedimentation and secondary impacts from

stream destabilization negatively influence mussel populations and other aquatic species,
including fish. We routinely recommend minimum 50' undisturbed natural buffers for
intermittent channels and minimum 100' undisturbed natural buffers for perennial
streams. We prefer stormwater management practices installed outside of jurisdictional
waters or in the area of development so that wider natural buffers can remain intact along
streams. Wooded floodplains should be preserved for their flood retention capabilities.
The proposed plan does not appear to provide recommended buffer widths.
Dispersed Low Impact Development (LID) techniques are encouraged for commercial
projects instead of using typical curbing, guttering and stormwater ponds. Information on
LID practices and measures can be found at www.lowimpactdevelop.ment.org. These
practices are indicated to provide improved water quality, mimic natural stream recharge,
and be land use efficient while costing less to construct than stormwater ponds. We
recommend that any stormwater management ponds or wetlands be constructed using
similar. planting.techniques as those described in the attached document. We believe that
these practices provide improved water quality and restore lost wildlife habitat benefits
while providing important ancillary health and social benefits. For this project, sediment
and erosion control measures may need to adhere to the design standards for sensitive
watersheds (15A NCAC 4B .0124). Post development runoff conditions should mimic
pre development conditions to the extent practicable. A wider 100' undisturbed forested
buffer along the remaining perennial stream should be provided if possible.
Thank you for the opportunity to review and comment on this project. If you have any
questions regarding these comments, please contact me at 336/769-9453.
Attachment: Piedmont Stormwater Pond and Mine Planting Recommendations
Cc: Steve Chapin, COE
Brookdale Development 3 July 21, 2004
Piedmont Stormwater Pond and Mine Planting Recommendations
Instead of using the typical fescue grasses or exotic plant species, the following mixtures should
be considered for lower elevation stormwater ponds and mine sites:
Spring/Summer Mixture, May 1- Sept. 15 Fall/Winter Mixture, Sept. 15 - April 30
Browntop millet 201bs/a Winter Wheat 120 lbs/a
Kobe lespedeza 20 lbs/a Kobe lespedeza 20 lbs/a
Shrub lespedeza 1 lb/a Shrub lespedeza 1 lb/a
Switchgrass* 5lb/a Switchgrass* 5lb/ac
Add to fall or spring plantings: `Tioga' Deertongue (Panicum clandestinum) at a rate of 7 lbs.
Pure Live Seeds (PLS) per acre.
* When possible on slopes less than 3:1 use Switchgrass instead of lespedezas and on slopes greater than
3:1 use Orchard Grass or Creeping Red Fescue. Other native species may be appropriate depending on
soil, slope, and region. Korean lespedeza may be appropriate in colder geophysical areas. We do not
recommend Sericea lespedeza. Native plants and warm season grasses are preferred over exotic plants.
Add one of the following to the above mixture:
Creeping Red Fescue 5 lbs/acre
Ladino Clover** 5 lbs/acre
Atlantic Coastal Panic Grass 5 lbs/acre (PLS)
Alfalfa** 5 lbs/acre (requires fertilizer containing Boron)
** Lime & fertilize disturbed areas according to NRCS soil test results and follow planting guidelines as
appropriate and necessary. Depending on elevation and region, other native species may be appropriate.
Note that mowing should be limited to late winter or early spring. Mowing should only occur as needed to
prevent unwanted tree growth on a 2-3 year schedule.
The provision of shade around impounded waters can significantly reduce thermal impacts. Trees
and shrubs (1 year bare root seedlings) should be planted randomly at a minimal rate of 100 trees
per acre on the top and upper portions of the structure and at a minimal rate of 150 per acre
around the normal water elevation and littoral shelf area. The following list of tree species may

Other species may be utilized depending on site requirements and native plant availability. Pines* should
not exceed 15% of the reforestation. No more than 20% of the tree species will be of a single species. An
80% success rate is acceptable over five years. Large or fast growing trees like Sycamore and Maple*
may not be appropriate near detention facility dams. Note: Non-native plants included in this list are
routinely considered beneficial and/or agriculturally established non-natives. They have been included as
they are readily available commercially and they do not exhibit many of the negative attributes of other
non-natives that tend to spread or inhibit native plant propagation and survival.
