Re: Neuse Buffer Authorization Request
Crabtree Commons
Raleigh, North Carolina
MFI -11010
Dear Ms. Smith:
On behalf of CVM Holdings, LLC, we are applying for an NC Division of
Water Quality (DWQ) Neuse Buffer Authorization for temporary and
permanent impacts to Neuse River Riparian Buffers associated with a multi-
family apartment project known as Crabtree Commons. The subject property
is 10.26 acres bound by existing Crabtree Valley Avenue to the north, existing
Creedmoor Road to the west, and existing Edwards Mill Road to the south, in
Raleigh, North Carolina., within the Neuse River Basin of North Carolina.

JURISDICTIONAL FEATURES: The subject property is adjacent and drains
to Crabtree Creek, which empties into the Neuse River (HUC 03020201). While
there are no streams and /or wetlands within the proposed property boundary, there
are offsite stream buffers that are proposed for impacts associated with infrastructure
improvements. The offsite property contains 397 l.f. of Perennial Stream and 509 l.f.
of Intermittent Stream in vicinity of off -site impacts. Both stream "A" and stream
"B" drain to Crabtree Creek, which is designated as Class C/NSW and subject to the
Neuse River Buffer Rules. Both stream features are depicted on the Wake County
Soils Survey (Fig. 2). There are no wetlands located within the project area. See
Figures 1 -3, for existing conditions.

PROJECT LOCATION/HABITAT: The subject property is 10.26 acres
bound by existing Crabtree Valley Avenue to the north, existing Creedmoor
Road to the west, and existing Edwards Mill Road to the south, in Raleigh,
North Carolina. Once a retail center, the property boundary is now vacant and
has been previously mass graded. The project also includes the future right -
of -way for the Edwards Mill Road Extension. The lot lines and stormwater
boundaries have all been adjusted to account for this future ROW and build
out.
Approximately 90 percent of the subject property can be characterized as
cleared /maintained /disturbed land with shrub /scrub vegetation, while 10
percent is comprised of sparsly forested areas along the riparian corridors to
the east of Edwards Mill Road. The riparian buffer is consists of mainly
loblolly pine, Red Maple, Tulip Poplar, a few Oaks species, with an
understory Chinese Privet, and vine species. The subject property is adjacent
and drains to Crabtree Creek, which empties into the Neuse River (HUC
03020201).
Land use within the vicinity of the project is a mix of retail /commercial,
multi - family, and industrial - office, and with little to no natural forested areas
outside of the project area. There is also City of Raleigh sanitary sewer
easements within and adjacent to the property and a greenway running along
the northern boundary of the property.
PROPOSED PROJECT/IMPACTS: The proposed project consists of a
multifamily housing development and infrastructure known as Crabtree
Commons. The proposed development is a 250 unit multi - family apartment
complex with associated utilities, parking, recreational amenity, stormwater
management and roadway improvements. Once a retail center, the property
boundary is now vacant and has been previously mass graded. The project
also includes the future right -of -way for the Edwards Mill Road Extension.
The lot lines and stormwater boundaries have all been adjusted to account for
this future ROW and build out. The multi - family apartments and all related
construction will be carried out by Martin Fein Interests, LTD. with the offsite
roadway and infrastructure improvements will be constructed on property
owned by CVM Holdings, LLC.

A majority of the proposed project avoids impacts to jurisdictional streams
and /or stream buffers (Figure 3 — Overall Impact Map). However, due to
required infrastructure improvements there are proposed impacts associated
with a turn lane widening along Edwards Mill Road and improvements to a
stormwater outfall along Crabtree Creek. There are 704 square feet of Zone 1
and 2,183 square feet of Zone 2 buffer impacts associated with Edwards Mill
Road widening. While there are no direct stream impacts, due to the pre-
existing alignment of Edwards Mill Road running parallel to Streams A and
B, there was no way to widen the road without making parallel impacts to
Zones 1 and 2. Per the Neuse River Riparian Buffer Rules Table of Uses the
proposed activities are deemed an allowable use with mitigation. Riparian
buffer mitigation will be provided through a mitigation banker described
below. A headwall is to be installed along the perimeter of the fill needed to
construct the turn lane, which minimizes impacts to the buffer and avoids
direct impacts to Streams A and B (Figure 4: Inset 1).
A portion of the stormwater outfall for the project will tie into an existing
RCP to the north along Crabtree Creek, which is currently a 24" pipe and will
be replaced with a 36' pipe. Although there is not a dissipater at this time, the
northern most 36" RCP will have a 20' velocity dissipater installed, which
will diffuse some of the low storm flows before it reaches Crabtree Creek. The
construction corridor for installation of the RCP and velocity dissipater along
Crabtree Creek has been minimized to the maximum extent practicable, and
the new velocity dissipater and improved outfall will help diffuse erosive
velocities during high -flow storm events, however there are temporary
impacts of 515 square feet of Zone 1 and 300 square feet of Zone 2 buffer and
permanent impacts of 240 square feet of Zone 1 and 600 square feet of Zone 2
buffer, all of which are allowable uses within table of uses (Figure 4: Inset 2).
A pre - application meeting was held with Ms. Cherri Smith of NCDWQ on
April 3, 2013.

AVOIDANCE and MINIMIZATION: Impacts to jurisdictional streams
and stream buffers have been minimized to the maximum extent practicable,
however due to required infrastructure improvements there are proposed
impacts associated with a turn lane widening along Edwards Mill Road and
improvements to a stormwater outfall along Crabtree Creek. A headwall is to
be installed along the perimeter of the fill needed to construct the turn lane,
which minimizes impacts to the buffer and avoids direct impacts to Streams A
and B. The construction corridor for installation of the RCP and velocity
dissipater along Crabtree Creek has been minimized to the maximum extent
practicable, and the new velocity dissipater and improved outfall will help
diffuse erosive velocities during high -flow storm events.
MITIGATION: Mitigation is proposed due to the parallel impacts to the
riparian buffer associated with the Edwards Mill Road widening. This is an
allowable use with mitigation within the Neuse River Buffer Rules Table of
Uses. Mitigation is proposed in the form of payment to an approved
mitigation bank. 5,387 buffer credits have been reserved from the Lane Island
Bank Parcel bank in the Neuse River HUC 03020201 and are proposed to
offset these buffer impacts. The reservation letter from Restoration Systems is
included.

STORMWATER MANAGEMENT: Per City of Raleigh stormwater
management regulations, peak flow rate detention is required for the 2 -year
and 10 -year storm events. However, the site is exempt from detention
requirements under 10- 9023(b)(3) due to possible negative impacts /flooding
downstream.
For the area that drains to the southeast (Sub -Basin 2), a pre - development to
post- development analysis has been performed to show that peak flow rates
for both the 2 -year and 10 -year storm events decrease as a result of the
development (including the proposed ROW and build -out of the Edwards Mill
Road Extension). The point of analysis for this Sub -Basin 2 area is the
eastern property line. Since stormwater flows over this remaining property
before entering the FEMA floodplain, an analysis has been done to
demonstrate that peak flow rates are decreased as a result of the development.
Since peak flow rates are decreased and diffuse there is no structural diffuse
flow device proposed. For the areas draining to Crabtree Creek, since
Crabtree Creek is a FEMA floodplain and providing peak flow rate detention
could potentially delay the post- development hydrograph peak to be closer to
the peak flow rate hydrograph for the Crabtree Creek floodplain, the site is
exempt from detention requirements under 10- 9023(b)(3).The courtyard areas
at this time are assumed to be impervious. The final layout of the courtyards
is to be determined.
The analysis for Sub -Basin 1 (to Crabtree Creek) shows that for Sub -Basin
IA, the existing crossing to Crabtree Creek with the 18" RCP system will
need to be upsized to handle the proposed build out and drainage areas for a
portion of Lot 2 and full build out of Lot 3 (assumed to be 90% impervious for
this analysis and assumed to all drain to Sub -Basin IA). This pipe system will
need to be upsized to a 36" system with the 10 -year HGL staying below the
crown of the pipe.
For Sub -Basin 1B, the existing 36" storm drain system across Crabtree Valley
Avenue is adequate for the proposed Sub -Basin 113 drainage area and
therefore does not need to be upsized for the proposed development. This
analysis for Sub -Basin 1 (lA and 1B) accounts for the future construction of
the proposed Edwards Mill Road Extension, storm drain system, proposed
impervious areas, and adjacent off -site drainage areas from the south.
Therefore based on these analysis points, the adjacent floodplain, the
adequacy of the existing and proposed storm drain pipes to convey storm
flows to the FEMA floodplain, and the exemption under 10- 9023(b)(3), no
peak flow rate detention is proposed.
The storm flows will be taken to existing storm outlets into Crabtree Creek.
Due to the flooding frequency of Crabtree Creek in this location, the inverts of
the (2) 36" RCP will be at water level of Crabtree Creek during high storm

flows. Although there is not a dissipater at this time, the northern most 36"
RCP will have a 20' velocity dissipater installed, which will diffuse some of
the low storm flows before it reaches Crabtree Creek, and during high flow
events it is anticipated that Crabtree Creek will be close to the invert of the
RCP, therefore it is not practicable to provide a level- spreader type device in
this location.
Proposed Stormwater Management Facility
For water quality and nitrogen export, the City of Raleigh Apportioning
Method was used to calculate a new site area of 1.27 acres. This is based on
the proposed analysis lines for Lots 1 and 2 including the proposed Edwards
Mill Road Extension Right -of -Way. This analysis shows that nitrogen
reduction is required, which will be handled in a sand filter system. The sand
filter system captures runoff from 1.36 acres of impervious area (preliminary
impervious area for nitrogen export calculations) and the preliminary sizing is
for the 1" runoff event. This system will be located on Lot 1 and have an
upstream splitter box to divert the 1" runoff into the BMP, bypassing the
larger flows to the 36" system under Crabtree Valley Avenue. With this
proposed BMP, the nitrogen export rate is 9.68 # /ac /year with 7.71 # /year of
nitrogen to be bought as an offset payment.
Since the City of Raleigh is a delegated authority for NC DWQ Stormwater
Management Plans, the review and approval of the SWMP is part of the City
of Raleigh review process. Enclosed are (2) courtesy copies of the
Stormwater Management Plan sent to the City of Raleigh.
Consideration of this project is greatly appreciated. If you should have any

3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
The subject property is 10.26 acres bound by existing Crabtree Valley Avenue to the north, existing
Creedmoor Road to the west, and existing Edwards Mill Road to the south, in Raleigh, North Carolina. Once
a retail center, the property boundary is now vacant and has been previously mass graded. The project also
includes the future right -of -way for the Edwards Mill Road Extension. The lot lines and stormwater
boundaries have all been adjusted to account for this future ROW and build out.
Approximately 90 percent of the subject property can be characterized as cleared /maintained /disturbed land
with shrub /scrub vegetation, while 10 percent is comprised of sparsly forested areas along the riparian
corridors to the east of Edwards Mill Road. The riparian buffer is consists of mainly loblolly pine, Red
Maple, Tulip Poplar, a few Oaks species, with an understory Chinese Privet, and vine species. The subject
property is adjacent and drains to Crabtree Creek, which empties into the Neuse River (HUC 03020201).
While there are no streams and /or wetlands within the proposed property boundary, there are offsite stream
buffers that are proposed for impacts associated with infrastructure improvements. The offsite property
contains 397 l.f. of Perennial Stream and 509 l.f. of Intermittent Stream in vicinity of off -site impacts. Both
stream "A" and stream "B" drain to Crabtree Creek, which is designated as Class C/NSW and subject to the
Neuse River Buffer Rules. Both stream features are depicted on the Wake County Soils Survey (Fig. 2).
There are no wetlands located within the project area. See Figures 1 -3, for existing conditions.
Land use within the vicinity of the project is a mix of retail /commercial, multi - family, and industrial - office,
and with little to no natural forested areas outside of the project area. There is also City of Raleigh sanitary
sewer easements within and adjacent to the property and a greenway running along the northern boundary of
the property.

3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
397 l.f. of Perennial Stream / 509 I.f. of Intermittent Stream in vicinity of off -site impacts
3d. Explain the purpose of the proposed project:
The purpose of the proposed project is to provide multi - family housing to western area of Raleigh, NC..
3e. Describe the overall project in detail, including the type of equipment to be used:
The proposed project consists of a multifamily housing development and infrastructure known as Crabtree
Commons. The proposed development is a 250 unit multi - family apartment complex with associated utilities,
parking, recreational amenity, stormwater management and roadway improvements. Once a retail center, the
property boundary is now vacant and has been previously mass graded. The project also includes the future
right -of -way for the Edwards Mill Road Extension. The lot lines and stormwater boundaries have all been
adjusted to account for this future ROW and build out. The multi - family apartments and all related
construction will be carried out by Martin Fein Interests, LTD. with the offsite roadway and infrastructure
improvements will be constructed on property owned by CVM Holdings, LLC.
A majority of the proposed project avoids impacts to jurisdictional streams and /or stream buffers (Figure 3 —
Overall Impact Map). However, due to required infrastructure improvements there are proposed impacts
associated with a turn lane widening along Edwards Mill Road and improvements to a stormwater outfall
along Crabtree Creek. There are 704 square feet of Zone 1 and 2,183 square feet of Zone 2 buffer impacts
associated with Edwards Mill Road widening. While there are no direct stream impacts, due to the pre-
existing alignment of Edwards Mill Road running parallel to Streams A and B, there was no way to widen the
road without making parallel impacts to Zones 1 and 2. Per the Neuse River Riparian Buffer Rules Table of
Uses the proposed acitivities are deemed an allowable use with mitigation. Riparian buffer mitigation will be
provided through a mitigation banker described below. A headwall is to be installed along the perimeter of
the fill needed to construct the turn lane, which minimizes impacts to the buffer and avoids direct impacts to
Streams A and B (Figure 4: Inset 1).
A portion of the stormwater outfall for the project will tie into an existing RCP to the north along Crabtree
Creek, which is currently a 24" pipe and will be replaced with a 36' pipe. Although there is not a dissipater at
this time, the northern most 36" RCP will have a 20' velocity dissipater installed, which will diffuse some of
the low storm flows before it reaches Crabtree Creek. The construction corridor for installation of the RCP
and velocity dissipater along Crabtree Creek has been minimized to the maximum extent practicable, and the
new velocity dissipater and improved outfall will help diffuse erosive velocities during high -flow storm
events, however there are temporary impacts of 515 square feet of Zone 1 and 300 square feet of Zone 2
buffer and permanent impacts of 240 square feet of Zone 1 and 600 square feet of Zone 2 buffer, all of which
are allowable uses within table of uses (Figure 4: Inset 2).
A pre - application meeting was held with Ms. Cherri Smith of NCDWQ on April 3, 2013.
Typical construction equipment will be used such as a long -arm track -hoe, front end loader, and bush hog for
the initial clearing.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Impacts to jurisdictional streams and stream buffers have been minimized to the maximum extent practicable, however due
to required infrastructure improvements there are proposed impacts associated with a turn lane widening along Edwards
Mill Road and improvements to a stormwater outfall along Crabtree Creek. A headwall is to be installed along the
perimeter of the fill needed to construct the turn lane, which minimizes impacts to the buffer and avoids direct impacts to
Streams A and B. The construction corridor for installation of the RCP and velocity dissipater along Crabtree Creek has
been minimized to the maximum extent practicable, and the new velocity dissipater and improved outfall will help diffuse
erosive velocities during high -flow storm events.

PCN Form — Version 1.3 December 10, 2008 Version

1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Proper sedimentation and erosion control methods will be utilized during all phases of construction and installation as
described in the Erosion Control Plan sheet reviewed and approved by the NC Division of Land Quality and City of
Raleigh. All work will take place during dry conditions and can be facilitated from high, non jurisdictional, stable ground
adjacent to the Neuse Buffer. The contractor shall install silt fence, inlet protection, sediment traps, diversion ditches,
tree protection, clearing only as necessary to install these devices. All erosion and sediment control measures will be
checked for stability and operation following every runoff producing rainfall , but in no case less than once every week.
Any needed repairs will be made immediately to maintain all measures designed. An erosion control inspections report
is required and will be kept by the owner's representative.
Temporary seeding and permanent seeding plans are included to restore most the buffer areas which will not be
permanently impacted by the new outfall structure.

1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified
® Yes ❑ No
within one of the NC Riparian Buffer Protection Rules?
1 b. If yes, then is a diffuse flow plan included? If no, explain why.
Comments:
Per City of Raleigh stormwater management regulations, peak flow rate
detention is required for the 2 -year and 10 -year storm events. However, the
site is exempt from detention requirements under 10- 9023(b)(3) due to
possible negative impacts /flooding downstream.
For the area that drains to the southeast (Sub -Basin 2), a pre - development to
post - development analysis has been performed to show that peak flow rates
for both the 2 -year and 10 -year storm events decrease as a result of the
development (including the proposed ROW and build -out of the Edwards
Mill Road Extension). The point of analysis for this Sub -Basin 2 area is the
eastern property line. Since stormwater flows over this remaining property
before entering the FEMA floodplain, an analysis has been done to
demonstrate that peak flow rates are decreased as a result of the
development. Since peak flow rates are decreased and diffuse there is no
structural diffuse flow device proposed. For the areas draining to Crabtree
Creek, since Crabtree Creek is a FEMA floodplain and providing peak flow
rate detention could potentially delay the post - development hydrograph peak
to be closer to the peak flow rate hydrograph for the Crabtree Creek
floodplain, the site is exempt from detention requirements under 10-
9023(b)(3). The courtyard areas at this time are assumed to be impervious.
The final layout of the courtyards is to be determined.
® Yes ❑ No
The analysis for Sub -Basin 1 (to Crabtree Creek) shows that for Sub -Basin
1 A, the existing crossing to Crabtree Creek with the 18" RCP system will
need to be upsized to handle the proposed build out and drainage areas for a
portion of Lot 2 and full build out of Lot 3 (assumed to be 90% impervious
for this analysis and assumed to all drain to Sub -Basin 1 A). This pipe
system will need to be upsized to a 36" system with the 10 -year HGL
staying below the crown of the pipe.For Sub -Basin 1B, the existing 36"
storm drain system across Crabtree Valley Avenue is adequate for the
proposed Sub -Basin 1B drainage area and therefore does not need to be
upsized for the proposed development. This analysis for Sub -Basin 1 (lA
and 1B) accounts for the future construction of the proposed Edwards Mill
Road Extension, storm drain system, proposed impervious areas, and
adjacent off -site drainage areas from the south. The storm flows will be
taken to existing storm outlets into Crabtree Creek. Due to the flooding
frequency of Crabtree Creek in this location, the inverts of the (2) 36" RCP
will be at water level of Crabtree Creek during high storm flows. Although
there is not a dissipater at this time, the northern most 36" RCP will have a
20' velocity dissipater installed, which will diffuse some of the low storm
flows before it reaches Crabtree Creek, and during high flow events it is
anticipated that Crabtree Creek will be close to the invert of the RCP,
therefore it is not practicable to provide a level- spreader type device in this
location.

2b. Does this project require a Stormwater Management Plan?
® Yes ❑ No
2c. If this project DOES NOT require a Stormwater Management Plan, explain why:
2d. If this project DOES require a Stormwater Management Plan, then provide a brief, narrative description of the plan:
Per City of Raleigh stormwater management regulations, peak flow rate detention is required for the 2 -year
and 10 -year storm events. However, the site is exempt from detention requirements under 10- 9023(b)(3) due
to possible negative impacts /flooding downstream.

floodplain, the site is exempt from detention requirements under 10- 9023(b)(3).The courtyard areas at this
time are assumed to be impervious. The final layout of the courtyards is to be determined.
The analysis for Sub -Basin 1 (to Crabtree Creek) shows that for Sub -Basin IA, the existing crossing to
Crabtree Creek with the 18" RCP system will need to be upsized to handle the proposed build out and
drainage areas for a portion of Lot 2 and full build out of Lot 3 (assumed to be 90% impervious for this
analysis and assumed to all drain to Sub -Basin IA). This pipe system will need to be upsized to a 36" system
with the 10 -year HGL staying below the crown of the pipe.
For Sub -Basin 1B, the existing 36" storm drain system across Crabtree Valley Avenue is adequate for the
proposed Sub -Basin 113 drainage area and therefore does not need to be upsized for the proposed
development. This analysis for Sub -Basin 1 (lA and ,1B) accounts for the future construction of the proposed
Edwards Mill Road Extension, storm drain system, proposed impervious areas, and adjacent off -site drainage
areas from the south.
Therefore based on these analysis points, the adjacent floodplain, the adequacy of the existing and proposed
storm drain pipes to convey storm flows to the FEMA floodplain, and the exemption under 10- 9023(b)(3), no
peak flow rate detention is proposed.
Proposed Stormwater Management Facility
For water quality and nitrogen export, the City of Raleigh Apportioning Method was used to calculate a new
site area of 1.27 acres. This is based on the proposed analysis lines for Lots 1 and 2 including the proposed
Edwards Mill Road Extension Right -of -Way. This analysis shows that nitrogen reduction is required, which
will be handled in a sand filter system. The sand filter system captures runoff from 1.36 acres of impervious
area (preliminary impervious area for nitrogen export calculations) and the preliminary sizing is for the 1"
runoff event. This system will be located on Lot 1 and have an upstream splitter box to divert the 1" runoff
into the BMP, bypassing the larger flows to the 36" system under Crabtree Valley Avenue. With this
proposed BMP, the nitrogen export rate is 9.68 # /ac /year with 7.71 #/year of nitrogen to be bought as an
offset payment.

Subject: Riparian Buffer Credit Reservation Letter
Dear Mr. Fein:
Restoration Systems has reserved +/ -5,387 sqft of riparian buffer offset credits at a price
