application
The project area Is approximately 0 51 acre In extent and Is comprised of single family residences with maintained landscaping, road right of way, and
a small
undeveloped wooded area Dominant vegetation within the project area consists of willow oak (Quercus phellos), English Ivy (Hedera helix)
Japanese honeysuckle (Lonicera japonica), Japanese privet (Llgustrum japonicum), poison Ivy (Toxlcodendron radlcans), and fescue (Festuca sp )
3b
List the total estimated acreage of all existing wetlands on the property 0

3d
Explain the purpose of the proposed project
The residence
at 5601 Robmhood Road is located to a low point and the garage of the house experiences flooding during rainfall events Currently storm flows are bypassing the existing storm drainage system inlets and
flowing
down the continuation of Deveron Drive right -of -way to 5601 Robmhood Road The purpose of the proposed project is to grade a low embankment across this valley to intercept surface runoff and prevent the
flooding of the garage In order to achieve this it will be necessary to extend the existing 36 -inch pipe system upstream by approximately 66 linear feet resulting to impacts to Stream A See letter for further detail
3e
Describe the overall project In detail, including the type of equipment to be used
he existing
36 pipe will be extended upstream resulting in 63 If of permanent stream impacts A rip rap apron at the new pipe inlet will result in an additional 3 If of permanent impacts The existing stream channel

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or

1 The Corps of Engineers believes that there may be jurisdictional waters of the
United States on the subject site, and the permit applicant or other affected party
who requested this preliminary JD is hereby advised of his or her option to
request and obtain an approved jurisdictional determination (JD) for that site
Nevertheless, the permit applicant or other person who requested this
preliminary JD has declined to exercise the option to obtain an approved JD in
this instance and at this time
2 In any circumstance where a permit applicant obtains an individual permit, or
a Nationwide General Permit (NWP) or other general permit verification requiring
"pre- construction notification" (PCN), or requests verification for a non - reporting
NWP or other general permit, and the permit applicant has not requested an
approved JD for the activity, the permit applicant is hereby made aware of the
following (1) the permit applicant has elected to seek a permit authorization
based on a preliminary JD, which does not make an official determination of
Jurisdictional waters, (2) that the applicant has the option to request an approved
JD before accepting the terms and conditions of the permit authorization, and
that basing a permit authorization on an approved JD could possibly result in less
compensatory mitigation being required or different special conditions, (3) that
the applicant has the right to request an individual permit rather than accepting
the terms and conditions of the NWP or other general permit authorization, (4)
that the applicant can accept a permit authorization and thereby agree to comply
with all the terms and conditions of that permit, including whatever mitigation
requirements the Corps has determined to be necessary, (5) that undertaking
any activity in reliance upon the subject permit authorization without requesting
an approved JD constitutes the applicant's acceptance of the use of the
preliminary JD, but that either form of JD will be processed as soon as is
practicable, (6) accepting a permit authorization (e g , signing a proffered
individual permit) or undertaking any activity in reliance on any form of Corps
permit authorization based on a preliminary JD constitutes agreement that all
wetlands and other water bodies on the site affected in any way by that activity
are Jurisdictional waters of the United States, and precludes any challenge to
such Jurisdiction in any administrative or judicial compliance or enforcement
action, or in any administrative appeal or in any Federal court, and (7) whether
the applicant elects to use either an approved JD or a preliminary JD, that JD
will be processed as soon as is practicable Further, an approved JD, a proffered
individual permit (and all terms and conditions contained therein), or individual
permit denial can be administratively appealed pursuant to 33 C F R Part 331,
and that in any administrative appeal, jurisdictional issues can be raised (see 33
C F R 331 5(a)(2)) If, during that administrative appeal, it becomes necessary
to make an official determination whether CWA jurisdiction exists over a site, or
to provide an official delineation of jurisdictional waters on the site, the Corps will
provide an approved JD to accomplish that result, as soon as is practicable
This preliminary JD finds that there "may be" waters of the United States on the
subject project site, and identifies all aquatic features on the site that could be
affected by the proposed activity, based on the following information

Dear Mr Blackwell
Thank you for the opportunity to provide information from the North Carolina Natural Heritage Program
(NCNHP) database for the proposed project referenced above The NCNHP database does not show any
records for rare species, important natural communities, natural areas, or conservation /managed areas
within the proposed project area as defined by Geographic Information System (GIS) data submitted
with your request for information
Within one mile of the proposed project area, the NCNHP shows element occurrence records for the
following rare species
'For status and accuracy definitions, please see the Rare Species Status Definitions and Element Occurrences documents at
' https / /ncnhde natureserve org /content /help
The occurrence record for Tall Larkspur has very low accuracy due to the lack of site- specific locational
Information associated with the record, but this species has been documented from the Charlotte area
In addition, the NCNHP database shows records for six properties considered to be Mecklenburg County
open space within one mile of the project area, the closest of which are the Rama Road Neighborhood
Park located ca 0 3 miles northeast of the project area, and a portion of the McMullen Creek Greenway
located ca 0 4 miles northwest of the project area The locations of conservation /managed areas near
the project area may be viewed by accessing the Natural Heritage Data Explorer online map viewer, or
by downloading and using GIS data, both options are available from the NCNHP Data Services webpage
(www ncnhp org)
Please note that although the NCNHP database may not show records for rare species within the
proposed project area, it does not necessarily mean that they are not present, it may simply mean that
the area has not been surveyed Occurrences of rare species documented within one mile of the
proposed project area increase the likelihood that these species may be present within the project area

Jurisdictional Determination
On January 29, 2015, HDR scientist Thomas Blackwell, Professional Wetland Scientist (PWS),
delineated jurisdictional waters of the U S within the project area Jurisdictional areas were
delineated using the U S Army Corps of Engineers (USACE) Routine On -Site Determination
Method This method is defined in the 1987 Corps of Engineers Wetlands Delineation Manua 14 with
further technical guidance from the Eastern Mountains & Piedmont Regional Supplements, dated
April 2012 A Wetland Determination Data Form representative of non- jurisdictional upland areas
has been attached (DP1) No jurisdictional wetlands are located within the project limits
Jurisdictional stream channels were classified according to recent USACE and N C Division of
Water Resources (NCDWR) guidance These classifications Included sampling with a D- shaped dip
net, taking photographs, and defining approximate breakpoints (location at which a channel
changes classification) within each on -site stream channel A NCDWR Stream Classification Form
and USACE Stream Quality Assessment Worksheet representative of Stream A are attached
(SCP1)
The results of the on -site field investigation indicate that there is one jurisdictional stream channel
(Stream A) located within the project area (Figure 5, attached) Stream A Is an unnamed tributary to
McMullen Creek McMullen Creek is within the Santee River basin (HU# 03050103)6 and is
classified as "Class C' waters by the NCDWR On -Site jurisdictional waters of the U S are
summarized in Table 1, below

RELATIVELY PERMANENT WATERS WITH PERENNIAL FLOW
Perennial Relatively Permanent Waters (RPWs) are those that typically have year -round flow
These streams typically have greater biological resources than Seasonal RPWs and Non -RPWs
and are capable of supporting those resources that require perennial flow This section describes
the on -site Perennial RPW stream and the field observations supporting this determination
Stream A emerges from an existing pipe in southeastern portion of the project area and flows
northwest across the project area for approximately 151 linear feet before entering another pipe
system Stream A exhibited a strong bed and bank, moderate substrate sorting, moderate flow, and
an average ordinary high water width of three to four feet Biological sampling revealed a weak
presence of macrobenthos and amphibians (caddis flies, pouch snails, and salamanders) Stream
characteristics indicate that continuous flow is present year -round in a typical year Stream A was
classified as a RPW with perennial flow according to USACE /EPA guidance Stream A scored 44
out of a possible 100 points on the USACE Stream Quality Assessment Worksheet and 30 out of a
possible 63 points on the NCDWR Stream Classification Form, indicating perennial status (SCP1,

Agency Correspondence
CULTURAL RESOURCES
A letter was forwarded to the N C State Historic Preservation Office (SHPO) on February 3, 2015 to
determine the presence of any areas of architectural, historic, or archaeological significance that
would be affected by the project As of the date of submittal, no response has been received from
the SHPO HDR also consulted the SHPO online GIS service? and the Charlotte Mecklenburg
Historic Landmarks Commission database and found no sites of architectural, historical, or
archaeological significance within the project limits
PROTECTED SPECIES
A letter was forwarded to the N C Natural Heritage Program (NHP) on February 3, 2015 to
determine the presence of any federally - listed, candidate endangered, threatened species or critical
habitat located within the project area In a response letter, dated February 17, 2015, the NCNHP
Stated that, "The NCNHP database does not show any records for rare species, important natural
communities, natural areas, or conservation /managed areas within the proposed project area "
Purpose and Need for the Project
The residence at 5601 Robinhood Road is located in a low point and the garage of the house
experiences flooding during rainfall events Currently, storm flows from properties located on
Deveron Drive and the upstream roadway are bypassing the existing storm drainage system inlets
and flowing down the continuation of Deveron Drive right -of -way to 5601 Robinhood Road

During earlier storm drainage Improvements (Addison Drive CIP USACE Action ID's 200430774-
776 and DWQ# 04- 0568), overloaded storm drainage systems were re- routed to additional
drainage pipes The storm drainage system was sized to handle 10 -year storm to protect the road
from flooding However, the existing stream channel, located on private property was not Improved
Currently, large rain events create flows that exceed the channel capacity and /or the storm system
capacity resulting In overland runoff flows along the right -of -way and Into the garage Modelling of
the existing stream channel and roadway drainage system Indicates that the channel capacity Is
exceeded during the 25 -year storm and the roadway drainage system capacity is exceeded In
storms above a 50 -year magnitude Any flow exceeding the channel or the roadway drainage
capacity runs towards the garage
The terrain at the end of Deveron Drive offers a valley shaped passage for water to flow towards
the garage The purpose of the proposed project Is to grade a low embankment across this valley to
intercept surface runoff and prevent the flooding of the garage The embankment shall retain the
storm water exceeding the capacity of the open channel and the residential roadway storm
drainage system and limit the flow to the capacity of single 36 -inch pipe inlet that will be then be
safely conveyed by a 48 -inch RCP from the existing manhole located in the driveway further
downstream In order to create the proposed embankment it will be necessary to extend the
existing 36 -inch pipe system upstream by approximately 63 linear feet A concrete riser box inlet will
be constructed at the inlet of the new pipe and the stream bed will be graded upstream to ensure a
stable transition to the pipe (Figure 6, attached)
Avoidance and Minimization
Impacts to on -site jurisdictional waters of the U S have been reduced to the maximum extent
possible Proper sediment and erosion control measures will be used to minimize disturbances to
downstream waters A pump around will be utilized to ensure that all work Is conducted In the dry
The proposed pipe extension has been kept to the minimum necessary to construct the berm to
protect the property The proposed rip rap apron at the pipe Inlet will be keyed in and embedded at
the channel bottom
Proposed Impacts to Jurisdictional Waters
Unavoidable permanent impacts to jurisdictional waters of the U S are limited to a total of 101
linear feet (0 01 acre) of perennial RPW stream channel Temporary Impacts will total
approximately 35 linear feet of Perennial RPW stream channel (Figure 6, attached)
Extending the existing 36 -Inch diameter reinforced concrete pipe (RCP) and riser box Installation
will impact approximately 63 linear feet of Stream A A rip rap apron will be Installed at the inlet of
the newly extended pipe resulting in an additional three linear feet of permanent stream impact
(Figure 6, attached) In accordance with City of Charlotte's design standards, the rip rap apron is
necessary to protect the pipe inlet

In addition, CMSWS proposes to enhance the existing channel for 35 linear feet upstream of the
new pipe and rip rap apron (Figure 6, attached) This proposed channel Improvements will consist
of reshaping the channel and stabilizing the stream banks The proposed stabilization will be
achieved by laying back the stream banks and installing a coir fiber log toe along the outside bend
of the stream A cross section of the proposed bank stabilization is provided on Figure 7 (attached)
Biodegradable coir fiber matting will also be used to stabilize the stream bank There will be no
permanent matting or hard stabilization used During construction a temporary rock check dam will
be installed at the upstream end of the work area and a pump around will be used to dewater the
channel to ensure that all work is conducted in the dry This rock check dam will be removed once
construction is complete The proposed channel improvements will result in a permanent impact to
35 linear feet of stream channel but no net loss of waters of the U S
