OFNR WATER Qdr -.LITY
Attached is a pre construction application for the Gates of Ethan s Glen project located on the
south side of NC Hwy 98 between NC Hwy 50 and Peed Road (SR 1846) north of Raleigh
Wake County North Carolina
The proposed project is a residential subdivision Mr Thomas Brown of the USACE issued
Nationwide Permit 39 authorizing 84 linear feet of stream impact to construct a road crossing for
the project (AID #200620209) NCDWQ issued a 401 Water Quality Certification approval
(DWQ Project # 05 2134) for 82 linear feet of stream channel impact 5 675 square feet (SF) of
Zone 1 riparian buffer, and 2,636 SF of Zone 2 riparian buffer to construct the road crossing
The level spreader proposed to diffuse flow from the project in the original PCN application did
not include bypass channels The locations proposed for these level spreaders have been
changed and their designs updated to current standards, which would result in 1 508 square feet
(SF) of Zone 1 riparian buffer and 929 SF of Zone 2 riparian buffer impact

SPECIAL PERMIT CONDITIONS
Requiring payment into the North Carolina Ecosystem Enhancement Program
In order to compensate for impacts to 82 linear feet of stream the permittee shall make payment to the
North Carolina Ecosystem Enhancement Program (NC EEP) in the amount determined by the NC EEP
sufficient to perform the restoration of 164 linear feet of warm water stream in the Neuse River Basin
(Cataloging Unit 03020201)
Construction within jurisdictional areas on the property shall begin only after the pernuttee has made full
payment to the NC EEP and provided a copy of the payment documentation to the Corps and the NC EEP
has provided written confirmation to the Corps that it agrees to accept responsibility for the mitigation
work required in compliance with the MOU between the North Carolina Department of Environment and
Natural Resources and the United States Army Corps of Engineers Wilmington District dated November
4 1998
Regional Conditions
For all NWPs that involve construction of culverts measures will be included in the construction that will
promote the safe passage of fish and other aquatic organisms For all culvert construction activities the
dimension pattern and profile of the stream (above and below a pipe or culvert) should not be modified
by widening the stream channel or by reducing the depth of the stream Culvert inverts will be burred at
least one foot below the bed of the stream for culverts greater than 48 inches in diameter For culverts 48
inches in diameter or smaller culverts must be buned below the bed of the stream to a depth equal to or

PROJECT NARRATIVE
The development of the Gates at Ethan s Glenn subdivision required the crossing of an existing stream
which is designated as a Jurisdictional Stream and at a location where Neuse Riparian Buffers (NRB) were
required Subsequently this crossing required that stormwater run off from the road ditches needed to be
dispersed or dissipated prior to entering the 50 foot NRB It is required that the 1st flush or 1 24hr storm be
handled by dispersement so as to prevent the flow from being concentrated as it flows thru the NRB To
accomplish this task Level Spreaders were designed for all four corners of the road s crossing of the stream As
lots were sold and recorded and the property developed it was found that insufficient easement space had been
allotted for the installation of the originally proposed level spreaders and they could not be installed
To correct this the site investigation found that it was possible to collect the 1St flush flows and divert
them to a single source Level Spreader to be located at one of the (south west) remaining un sold corners This
Report represents the design analysis of how this new design is to be accomplished Basically the Ist flush from
the north east and north west quadrants will be diverted to a level spread of approximately 1001f on the south
west quadrant Flow from the south east quadrant will be handled in and at that location The normal flows from
the south west quadrant will be handled with a 2nd Level Spreader of about 100 If
DRAINAGE DELINEATIONS and HYDROLOGY
Careful review and comparison of the existing conditions and the original design plans were conducted
to insure the actual stormwater flows are still as they were designed The design of the Level Spreaders will be
based upon the drainage delineations as shown on the design plans which accompany this report To design the
level spreaders we must know 2 flow volumes the 1St flush or 1 24hr storm and the 10 yr storm which is
required of NCDOT ditches The Ditches will be adapted with Ditch Blocks to capture the 1 st flush but allow
the larger flows to bypass directly to the stream
It is important to note here that the method of computation for determining these flows will be the
Rational Method Wake County typically prefers that the SCS method be used but that method is more suited to
larger areas and does not give an accurate representation of flow for an existing development with very small
drainage basins

BMP SYSTEM HYDRAULICS
Ditch Blocks
In accordance with the NCDENR stormwater BMP manual the Level Spreader must be designed for the
first flush run off volume That first flush volume is defined as the 1 /hr storm intensity In addition we will
also analyze the 10 yr storm event to enable us to design the proper depths of the roadside ditches and ditch
blocks
Ditch Blocks are berms built in the ditch line at the height of the first flush flow When the first flush
occurs it is trapped by the ditch block and feed via a yard inlet and connecting outlet pipe to the proposed Level
Spreader Any flow deeper than the first flush is allowed to flow over the ditch block and into the stream as a
concentrated storm flow

DESIGN CONVEYANCE PIPES
To convey the proposed 1St flush stormwater to the appropriate level spreader location a yard inlet will
be placed to collect the water and transport it by gravity flow pipe This will be required in two locations one
for area A and one for area B From our design software we have determined that a 10 PVC will be needed
for area `A and an 8 PVC pipe is needed for area B They will be bored under the existing roadway to
allow the stormwater water to reach the intended Level Spreader located in Phase IV
Pipes will need to be designed to carry storm water from the 1St flush volume from each of the 2 north
road areas to the south west quadrant Area A will be a 10 PVC pipe and Area B" will need an 8 PVC
pipe The pipe hydraulics were computed and noted on the design plans and also as shown on the Culvert
Reports

LEVEL SPREADER DESIGNS
The Level Spreaders noted below were sized in accordance with the NCDENR BMP manual The Level
spreader is to handle the 1 /hr storm Intensity and must be 501f in length for every 1 cfs of flow volume

*as this is an estimation of potential flow we have determined that with the depth of flow being 0 04
( <1/2 ) and the velocity of 0 51 fps the device is acceptable and meets the intent of the maximum length rule
To verify the adequacy of the design lengths we have computed a broad crested weir analysis to
illustrate the effect of flow depth and flow velocities prevalent with these designs

Please note that both the velocity and the depth of flow are extremely low and it is not expected that
these devices will be subject to erosion or rills which would allow re concentration of overland flow

FOREBAY
There will be 2 locations where a forebay is needed at Level Spreaders #1 and #2 Level Spreader #3
does not need a forebay because it is feed from a combination of ditch/channel and overland flow The size of
the forebays are relevant to the impervious area of the contributing drainage basin and are generally 0 2% of the
impervious drainage basin area
The sizes are tabulated as follows

Operation and Maintenance Agreement
I will keep a maintenance record on this BMP This maintenance record will be kept in a
log in a known set location Any deficient BUT elements noted in the inspection will be
corrected repaired or replaced inmediately These deficiencies can affect the integrity
of structures safety of the public and the removal efficiency of the BW
Important maintenance procedures
— Immediately after the filter strip is established any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks)
— Once a year the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation
— Two to three tunes a year grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC 1993) Forested filter strips do not require this type of maintenance
— Once a year the soil will be aerated if necessary
— Once a year soil pH will be tested and line will be added if necessary
After the filter strip is established it will be inspected quarterly and within 24 hours
after every storm event greater than 10 inch (or 15 inches if m a Coastal County)
Records of operation and maintenance will be kept in a known set location and will be
available upon request.
