Re Allenbrook Westndge Storm Water Capital Improvement Project (CIP)
Jurisdictional Verification and Nationwide Permits (3 and 27) Request
Mecklenburg County North Carolina
To Whom It May Concern
HDR Engineering Inc of the Carolinas (HDR) on behalf of our client Charlotte Mecklenburg Storm Water
Services (CMSWS) is requesting a Jurisdictional Verification and authorization under a Nationwide Permit
(NWP) 3 (Maintenance) and a NWP 27 (Aquatic Habitat Restoration Establishment and Enhancement
Activities) for activities associated with the Allenbrook Westndge Storm Water Capital Improvement Project
(CIP) in Mecklenburg County (Figure 1 and Figure 2)
Proiect Description
The purpose of the Allenbrook Westndge CIP is to improve the performance of the existing neighborhood
storm drainage system upgrade the capacity of the three culvert crossings (Allenbrook Drive Lanewood
Place and Westndge Drive) and enhance aquatic habitat and water quality by restoring and enhancing
impaired stream channels on two unnamed tributaries (UT) to Paw Creek (Allenbrook Tributary and Westndge
Tributary)
CMSWS intends to conduct Rosgen based Priority II stream restoration activities on approximately 1270
linear feet (If) of Allenbrook Tributary Priority II restoration will consist of channel relocation bank grading and
stabilization floodplain bench excavation installation of in stream structures and riparian buffer
establishment These activities will be submitted for mitigation credits to the City of Charlotte s Mitigation Bank
Instrument (MBI) In addition stream enhancement activities are proposed on approximately 1850 If of
Allenbrook Tributary and approximately 1730 If of Westndge Tributary upstream of the restoration reach
totaling 3 580 If of enhancement Upstream stream enhancement activities will further benefit water quality in
this watershed A Site Specific Mitigation Plan (SSMP) has been submitted and approved by the Interagency
Review Team (IRT)

NWP 3 Impacts
Maintenance activities including culvert replacement and associated stabilization structures will result in
permanent fill impacts to jurisdictional waters The proposed storm water infrastructure has been designed in
accordance with the current Charlotte Mecklenburg storm drainage system design standards Three culvert
replacement locations each consisting of double reinforced box culverts (RCBC) will be staggered in
elevation to create a low flow culvert and a floodplain culvert These will be located entirely within the
footprint of the existing deteriorated structures In addition soil will be added to the bottom of the culverts to
create a more natural channel bottom Installing np rap aprons and adding stone to augment existing plunge
pools downstream of outfalls will help dissipate flows and protect the downstream channel Sediment and
erosion control devices will be installed and employed throughout the duration of the project Mitigation
requirements will be offset by the onsite stream restoration /enhancement activities Table 2 is a summary of
permanent stream impacts

D Impact Justification and Mitigation
1 Avoidance and Minimization
la Specifically describe measures taken to avoid or minimize the proposed impacts in designing project
The proposed stream restoration /enhancement activities are intended to improve water quality enhance instream aquatic
habitat and establish a native riparian buffer Stream banks will be sloped back and natural materials will be utilized to provide
bank stabilization and to create instream structures
The proposed storm water infrastructure has been designed according to the Charlotte Mecklenburg storm drainage system
criteria and standards Replacement double RCBCs have been designed to maintain low flow conditions and will be
constructed entirely within the footprint of the existing deteriorated structures These structures have been designed to the
shortest possible extent without compromising the intent of the proposed project
1 b Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques
The Erosion Control Plan adheres to the local and state requirements and control devices will be employed throughout the
duration of the project Tree protection fencing will be installed as noted on the construction plans Stream banks will be
stabilized using biodegradable matting and planted with native grasses trees and shrubs The contractor will only perform
work on a section of stream that can be stabilized in the same day and all other areas will be stabilized within 48 hours All
work in or adjacent to stream waters shall be conducted in a dry work area
Sod will be added to the bottom of the RCBCs to create a more natural channel bottom Rip rap aprons and adding stone to
augment existing plunge pools downstream of outfalls will help dissipate flows and protect the downstream channel

Habitat?
Obtained an updated list of federally protected species from the US Fish and Wildlife Services (FWS) website (http / /nc
es fws gov /es /countyfr html)
NC Natural Heritage Program (NHP) GIS coverage database search
Suitable habitat for Schweirntz s sunflower (Helianthus schweirntzu) was present with in the Project Area A pedestrian
survey was conducted during its flowering season and no individuals were present
The FWS concureed with our findings in a response dated November 22 2010 (FWS Log No 4 2 -09 105)
The NHP commented that the only rare species located within a mile of the Project Area is the long extirpated population
of the Federally Endangered Carolina heelsplitter (Lasmigona decorata) from Paw Creek The species was last noted in
this creek (specific location not well documented) prior to 1918 (correspondence dated January 12 2009)
6 Essential Fish Habitat (Corps Requirement)

NOAA Essential Fish Habitat Mapper
7 Historic or Prehistoric Cultural Resources (Corps Requirement)
7a Will this project occur in or near an area that the state federal or tribal
governments have designated as having historic or cultural preservation
❑ Yes ® No
status (e g National Historic Trust designation or properties significant in
North Carolina history and archaeology)?
7b What data sources did you use to determine whether your site would impact historic or archeological resources?
HDR reviewed the National Register of Historic Place (NRHP) GIS database and found no known structures or historic
districts located within a mile of the Project Area
Correspondence (dated January 7 2009) was sent to the NC State Historic Preservation Office (SHPO) requesting
information on cultural resources that may be impacted by the proposed project SHPO reviewed (ER 09 0043) the
project and commented that no historic resources would be affected (dated January 27 2009)

Dear Mr Mularski
The Natural Heritage Program has no record of significant natural communities significant natural
heritage areas or conservation /managed areas at the site nor within a mile of the project area The only
rare species location within a mile is the long extirpated population of the Federally Endangered Carolina
lieelsplitter (Lasmigona decorata) from Paw Creek The species was last noted in this creek (specific
location not well documented) prior to 1918
You may wish to check the Natural Heritage Program database websrte at www ncnhp org for a listing of
rare plants and animals and significant natural communities in the county and on the quad map Our
Program also has a new websrte that allows users to obtain information on element occurrences and
significant natural heritage areas within two miles of a given location
<http / /nhpweb enr state nc us /phis /public /gmap75_mam phtml> The user name is "public ` and the
password is 'heritage' You may want to click Help for more information
NC OneMap now provides digital Natural Heritage data online for free This service provides site
specific information on GIS layers with Natural Heritage Program rare species occurrences and
Significant Natural Heritage Areas The NC OneMap websrte provides Element Occurrence (EO) ID
numbers (instead of species name) and the data user is then encouraged to contact the Natural Heritage
Program for detailed information This service allows the user to quickly and efficiently get site specific
NHP data without visiting the NHP workroom or waiting for the Information Request to be answered b)

Dear Mr Mularski
Subject Federally Listed Species Assessment for Allenbrook Watershed Restoration
Project in Charlotte, Mecklenburg County North Carolina
On February 2, 2009 we provided you a letter with our comments on the subject project
In that letter we requested that a survey be conducted for the federally endangered
Schweinitz s sunflower (Hehanthus schweanatzaa) because suitable habitat existed within
the project area On October 29, 2010 we received correspondence from you that
included the results of a survey for Schweimtz s sunflower conducted by HDR The
following comments are based on our review of the information that you provided in that
letter and are in accordance with the provisions of the Fish and Wildlife Coordination
Act, as amended (16 U S C 661 667e) and section 7 of the Endangered Species Act of
1973, as amended (16 U S C 1531 1543) (Act)
Federally Listed Species - After reviewing the information that you provided we concur
with your conclusion that no listed species occur on the site We do not believe any
endangered or threatened species will be affected by the proposed project therefore the
requirements under section 7 of the Act are fulfilled However, obligations under
section 7 of the Act must be reconsidered if (1) new information reveals impacts of this
identified action that may affect listed species or critical habitat in a manner not
previously considered, (2) this action is subsequently modified in a manner that was not
considered in this review or (3) a new species is listed or critical habitat is determined
that may be affected by the identified action
We appreciate the opportunity to provide these comments If we can be of assistance or
if you have any questions, please do not hesitate to contact Mr Bryan Tompkins of our
staff at 828/258 3939, Ext 240 In any future correspondence concerning this project,
please reference our Log Number 4 2 09 105
8 A discussion about the extent to which the project will result in the loss,
degradation, or fragmentation of wildlife habitat from direct construction
impacts and from secondary development impacts
9 Mitigation measures that will be employed to avoid, eliminate, reduce, or
compensate for habitat value losses (wetland riverme, and upland) associated
with any phase of the proposed project
We appreciate the opportunity to provide these comments If we can be of assistance or if you
have any questions please do not hesitate to contact Mr Bryan Tompkins of our staff at
828/258 -3939, Ext 240 In any future correspondence concerning tlus project please reference

Dear Mr Mularski
Subject Listed Species Assessment Allenbrook Watershed Restoration Planning Project,
Charlotte, Mecklenburg County North Carolina
In your letter of January 7 2009, you requested our comments on the subject project We have
reviewed the information you presented and are providing the following comments in accordance
with the provisions of the Fish and Wildlife Coordination Act, as amended (16 U S C
661- 667e), and section 7 of the Endangered Species Act of 1973 as amended (16 U S C
1531 -1543) (Act)
Your letter does not include a description of the project or any potential impacts It is impossible
for us to give a detailed assessment without a complete set of plans that includes the exact
location of the project and specific details regarding project plans and construction techniques
The purpose of this letter is only to inform you of federally listed species that occur within the
geographical area indicated on the map you sent, and we have included a detailed list of
information that will be required for us to fully assess the potential direct indirect, and
cumulative impacts of any construction/development projects in this area
Endangered Species You stated in your letter that suitable habitat for the federally endangered
Schwetnitz's sunflower (Hehanthus schwetnazra) occurs within the proposed project area Our
records indicate that this species has been found near the proposed project site Your letter did
not indicate whether surveys have been conducted for tlus or other rare plant species within the
project impact area Unless the area has been specifically surveyed for this listed species or no
appropriate habitat exists, a survey should be conducted to ensure that this species is not
inadvertently lost We recommend that surveys for this species be conducted during its
flowering period (August t4rough October)
In accordance with the Act, before any federal authonzation/permits or funding can be issued for
this project, it is the responsibility of the appropriate federal regulatory /permitting agency(ies) to
determine whether the project may affect any federally endangered or threatened species (listed
species) or designated critical habitat If it is determined that this project may affect any listed
species or designated critical habitat, section 7 consultation with this office must be initiated
At this stage of project development and without more specifics about construction locations and
techniques it is difficult for us to assess potential environmental impacts (direct, mdirect and
cumulative) We therefore recommend that any environmental document prepared for this
project include the following (if applicable)
1 A complete analysis and comparison of the available alternatives (the build
and no -build alternatives)
2 An assessment of any development that will impact the 100 -year floodplain
3 A description of the fishery and wildlife resources within existing and
required additional rights -of -way and any areas such as borrow areas, that
may be affected directly or indirectly by the proposed project
4 The acreage and a description of the wetlands that will be filled as a result of
the proposed project Wetlands affected by the proposed project should be
mapped in accordance with the Federal Manual for IdentYfying and
Delineating Jurisdictional Wetlands We recommend contacting the
U S Army Corps of Engineers (Corps) to determine the need for a
Section 404 Clean Water Act permit Avoiding and mimmizmg wetland
impacts is a part of the Corps' permitting process, and we will consider other
potential alternatives in the review of any permits
5 The extent (linear feet as well as discharge) of any water courses that will be
impacted as a result of the proposed project A description of any streams
should include the classification (Rosgen 1995, 1996) and a description of the
biotic resources
6 The acreage of upland habitat by cover type, that will be eliminated because
of the proposed project
7 A description of all expected secondary and cumulative environmental
impacts associated with this proposed work The assessment should specify
the extent and type of development proposed for the project area once the
work is complete and how future growth will be maintained and supported
with regard to sewer lines, water lines, parking areas, and any proposed
roadways
