Re: Reply to the Division of Water Quality's 04/15/08 and 5/1/2008 request for
additional information
Buckhorn Place
Wake County, North Carolina
Dear Ms. Karoly and Mr. McMillan:
This letter is in response to your letter dated April 15, 2008 and May 1, 2008 which
requested additional information for the proposed Buckhorn Place. The following
restates your questions/comments and is then followed by our response.
Additional Information Requested on April 15, 2008
1. Please provide cross section details showing the provisions for aquatic
life passage for impacts shown on Inset 3.
Inset 3 shows permanent wetland fill and therefore, there are no provisions being made
for aquatic life as this wetland is at the top of an existing drainage. We are assuming you
were actually referring to Inset 1 which has two, 54" culverts proposed for the stream
crossing. We apologize in advance for the oversight of not including the profile view for
the proposed culvert crossing. Please see the attached crossing profile which
demonstrates the provisions for aquatic life passage (i.e. normal flow culvert buried 1
foot).
2. Please provide building envelopes for all lots with wetlands, streams
or buffers on lots shown in Inset 1 and 3.
Inset 1 has been revised to demonstrate the setbacks required by the City of Raleigh for
lots where there is some incidental encroachment. Basically, there is a required 20 foot
setback from the edge of Zone 2 of the buffer that cannot be built upon on the Eastern

side of the Creek. On the Western side of the Creek, there is a 5 foot setback from the
edge of Zone 2 as well as a 10 foot set back from the sanitary sewer line easement. In
essence, these lots are all buildable without future encroachments or impacts to the
protected riparian buffer.
Inset 3 doesn't demonstrate any lot encroachments into the wetland areas. As shown on
the maps previously supplied to the NC DWQ, the lot lines terminate well before the
wetland areas. In fact, the area around all remaining wetlands and streams on the subject
property that do not have any proposed impacts have been placed within a Resource
Conservation Area (RCA) as required by the City of Raleigh. Also, as stated above, there
is a 20 foot setback from the rear property line on all the lots in the proposed
development; therefore, any wetland areas that may be coincident with proposed lot lines
will be prevented from being impacted due to the required setbacks.
3. Please reconfigure the lots impacting wetlands on Inset 3 from two
lots to one lot to avoid impacts to wetlands.
The proposed development proposes impacts to less than 1/101h of an acre of wetland for
the entire project. This project is also required to place 10 percent of the overall acreage
within a Resource Conservation Area (RCA), Tree Save or Open Space provision. For
this development, that totals approximately 13 acres of preserved land, which includes
stream and wetland areas.
We have attached a copy of the City of Raleigh's Small Area Plan Urban maps and the
appropriate portion of the Raleigh Comprehensive Plan. The proposed Buckhorn
development falls within a "Focus Area" as determined by the City of Raleigh. This
"Focus Area" is intended to have a housing density of 7 to 15 units per acre (R7-R15).
This "Focus Area" is also intended to have a "mixed use core" of "retail, professional
services, civic and educational uses..."
In essence, the City of Raleigh is pushing for a higher density within the project
boundaries as it is a "Focus Area." The applicant was able to successfully negotiate with
the City of Raleigh to have this project re-Zoned to an R-4 (4 units per acre). Therefore,
the applicant has a requirement to maintain 4 lots per acre in addition to preserving 10%
of the overall project in an RCA or Open Space area. For this reason, the applicant is
proposing the small amount of lot fill on Inset 3 in order to meet the requirements of the 4
units per acre per as well as managing the 10% RCA/Open Space area. These two lots
cannot be recombined into 1 lot based on the subdivision review by the City of Raleigh.
Additionally, the topography of the area necessitates this small amount of lot fill in order
to make the lots buildable with the appropriate setbacks as required by Raleigh.
4. Please indicate the diffuse flow provision measures on the site plan
and submit diffuse flow provision measure supplement forms
(Supplement forms available on the DWQ website at
hqp: //h2o. enr.state. nc. us/su/bmp-forms. htm).
This information was supplied to the NC DWQ in our original submittal on March 28,
2008.
Additional Information Requested on May 1, 2008
Please provide clear labels for the level spreaders on the plan sheets
so that they can be easily cross-referenced with the forms and
calculations.
Please see the attached revised plan sheets on which the level spreaders have been clearly
labeled.
2. Based on the topographic information provided on Plan Sheet C-4D,
the filter strips are too steep to allow for diffuse flow at two level
spreaders: the level spreaders at Pond I and ADS1. Please either
relocate these level spreaders to locations where the filter strip slopes
are appropriate for level spreaders or provide BMPs that remove a
minimum of 85 percent TSS and 30 percent TNfrom the stormwater
generated by this project. In order to demonstrate that you have an
appropriate BMP design, you may either:
a. Provide a completed BMP Supplement Form, with all the required
items for review by the DWQ. The BMP Supplement Forms are
available at: http://h2o.enr.state.nc.us/su/bmp forms.htm. Please
include both the Design Summary and the Required Items
Checklist along with all the required items listed therein.
b. Provide one copy of a stormwater management plan showing
appropriate BMPs that has been approved by the City of Raleigh,
including plan details, calculations and other supporting
information.
The level spreaders located near Pond 1 and ADS 1 have been redesigned as requested by
Ms. Annette Lucas of DWQ during our May 28, 2008 meeting. ADS1 was re-designed
to leave the greater than 1 inch flows in the current location as well as removing the
dissipater pad; however, the SC 250 liner was to remain in place. The first inch of
rainfall was designed to enter a bio-retention cel as discussed during our May 28, 2008
meeting. The attached Plan Sheets C-4C and D-7 show the design criteria and
calculations used to size the devices.
3. The dissipater pad down slope of ADS #1 should not be placed directly
on a fill slope.
Please see the attached revised Plan Sheets C-4C which shows the presence of 1
dissipater pad sized accordingly, per our May 28, 2008 meeting.
4. It is not possible to evaluate the suitability of the filter strip down
slope of the level spreader at Pond 3. Plan sheet C-4D does not show
the entire filter strip to the top of stream bank. If there are appropriate
filter strip slopes, then see Item (S). If the filter strip slopes are too
steep for level spreaders at this location, then please see Item (2).
The filter strip and outlet structure were moved per our meeting with Annette Lucas on
May 28, 2008.
5. The level spreader at Pond 3 is directly flow directly toward the
dissipater pad down slope of the outlet of the flow splitting device.
Please reconfigure the design to avoid this problem.
Ms. Annette Lucas accepted the redesign of this level spreader during our May 28, 2008
meeting. Please see attached revised Plan Sheet C-4C.
Please also note that we have attached an approved copy of the Buckhorn Place
Stormwater Management Plan (SMP) to this correspondence. Per the new DWQ Policy
regarding Stormwater Management Plan Review and Approval, the City of Raleigh is
one of the locally delegated programs that have the authority to review SMPs. This
review by the City of Raleigh was occurring concurrently with DWQs review of the
project application package. The City of Raleigh just recently finalized and approved the
proposed SMP plan. We anticipate that this documentation, coupled with the above
supplied information and explanation will satisfy any outstanding issues for Buckhorn
Place. Please let us know if there is anything further that we can provide you with or do
for you in order to assist in expediting the 401 Approval for this project.
Please feel free to call me if you require any further explanation.
Sincerely,
icole J. Thomson
Regulatory Specialist

Origination of Plan
The Wake County Board of Commissioners adopted the East Raleigh /Knightdale Urban Service
Area (USA) Land Use Plan in May 2000. This plan was prepared for this Urban Service Area
jointly by Wake County, the Town of Knightdale and the City of Raleigh with the participation of
area residents and property owners through a citizen's task force.
An Urban Service Area is the land area in Wake County jurisdiction that has been designated
appropriate for municipal services and urban development patterns. Each municipality in Wake
Comity has a jointly adopted USA illustrated in the Wake County Land Use Plan. USA's are
further divided into Short-Range and Long-Range development time frames; the Short-Range
USA classification applies to land within those portions of a "sewershed" that municipal water
and sewer line extensions are projected to occur within 10 years. Municipal service extensions are
projected beyond 10 years in the Long-Range USA.
Plan Area
The Neuse River East Small Area Plan is based on the Wake County Plan and the U S 401 North
Corridor Plan and includes new recommend- ations for collector street loc ons, utilit er?ice

Focus Areas. Model design guidelines to support the Village Center concept are being prep
by the Raleigh Planning Commission-Strategic Plan cling Connnit-
f e.
Foci- s Areas are located in areas that accommodate a grid of cOHector streets, provide adequate
spacing between other focus areas, and avoid sensitive natural areas. The reconnriiended
development pattern within a Focus Area, referred to as a Village Center, includes medium to
high density residential uses and a mix of retail, office, civic and social facilities. The entire
development area is interconnected by a system of local streets and sidewalks to disperse traffic
and minimize walking distances. Site design plays an important role in creating the pedestrian
orientation within a Village Center as well as harmonizing the mix of uses. Commercial
buildings should be clustered together to minimize walking distance and set forward toward the
sidewalk and street with on-street parking and a pedestrian oriented streetscape. The streetscape
area should include building entrances, storefront windows, street trees, low level lighting,
seating and plaza areas. This streetscape design also provides a transition between conunercial
and residential development. On-street parking is encouraged adjacent to the sidewalk area as a
buffer to vehicular traffic and for customer convenience. Parking between sidewalk areas and
building fronts should be minimized. The development of individual properties within a Focus
Area must be coordinated to relate with each other in land use, scale, and intercon nectivity of
streets and sidewalks. Residential areas should include a mix of housing styles with greater
densities adjacent to the mixed-use center.
Outside a designated Focus Area, primarily low density residential uses are recommended.
Existing community retail service uses are recognized by the designation of Residential Retail
Area. Additional retail uses in these areas are strongly discouraged.
There are two types of focus area designations within the plan area, Neighborhood Focus and
Cornmur_uty Focus. A Neighborhood Focus includes 40 to 160 acres and is primarily residential
wiffFin a areva ge density of 4 to 10 units per acre. A mixed-use core of 4 to 20 acres provides
neighborhood shopping, professional services and social opportunities. Medium and high
density housing is appropriate within the core area. There are five Neighborhood Focus areas
identified on the Urban Form map in the vicinity of the following intersections, Forestville Road
' //_VS-401, Milburnie/Watkins Roads, Milburnie/RolesvilleRoads, Buffaloe/Rolesv' e ozazN; and

Transportation
The thoroughfare system is comprised of arterials, major thoroughfares, and minor
thoroughfares. U.S. Hwy 64, U.S. Hwy 401, and the proposed I-540 establish the primary arterial
network in the plan area. Major thoroughfares include Mitchell Mill Road, Buffaloe Road,
Forestville Road and the proposed Skycrest Drive extension Minor Thoroughfares include
Peeb -es Road and Old Crews Road. Peebles and Old Crews Roads create a north/south
connection along the eastern boundary of the plan area that could be improved upon by
upgrading the road to a Major Thoroughfare and realigning the intersection at Old Milburnie
Road to form a continuous movement-
Collector street locations are recommended to assure an adequate level of connectivity between
residential neighborhoods, to community service centers, and to local thoroughfares allowing for
the efficient dispersal of traffic throughout the network of roads. A partial system of collector
streets was recommended in the Joint U.S. 401 Perimunicipal Area Plan and adopted in 1992.
Building upon the US-401 Plan, additional collectors are recommended to interconnect the
expanded area of this plan.
Roadways should be designed to also accommodate walking and biking as alternative forms of
transportation. Convenient sidewalk connections within neighborhoods and to retail and
employment areas are necessary to support walking and transit service in the future. Bikeway
and greenway systems should also be included and interconnected to add to the grid of
alten-rative transportation corridors.
Utilities
Water and wastewater facilities are planned to allow the extension of these services to anticipated
development in the plan area over the next ten years. Raleigh's utility systems have been
planned in coordination with the Wake County Water/Sewer Plan, adopted in 1998 to coordinate
the logical and orderly expansion of water/sewer service within the defined Urban Service Areas
of Wake County.
Sanitary sewer lines in the area include the outfall line on the west side of the Neuse River and
the Harris Creek line. A 48" outfall line is funded by the CIP for fiscal year 2005 on east side of
Neuse River from an existing line north to the intersection with the Harris Creek line. Tl,e outfalll
is continued north to Louisburg Road as a 24" line in the second 5 rear schedule of the CIP.

extensions and 3 Neighborhood Park Search Areas are being recommended to meet the
recreational needs of the projected population in this portion of the city. The Neuse River fs a
major recreational corridor in Raleigh as detailed in the Neuse River Corridor Cornprehensive
Recreation Master Plan. Two major greemvay corridors extend from the Neese Ri v%,r into Nh-
plan area: Harris Creek and Beaver Darn Creek.
Harris Creek is located in the northern half of the plan area and is identified in the Raleigh Parks
and Greenway Plan as the Wake Crossroads Lake greenway. Tributary-A of Harris Creek
branches to the south and continues east past Old Crews Road into Raleigh's Long-Range USA.
Additions to both the Harris Creek and Tributary-A greenways are recommended to extend the
greenway corridors as shown on the Parks and Greenway Plan map. An additional greemvay
corridor is recommended along a creek extending east from the Neuse River through Neuse
Crossings and Neuse Point Village subdivisions and across Mitchell Mill Road. This extension
will provide a greenway connection to the Neighborhood Focus Area at Forestville and
Louisburg Roads.
A pair of lakes, Beaver Dam and Neuseoca, and Beaver Dam Creek forms the southern greenway
corridor in the plan area. A large portion of the Beaver Dam Creek greenway extends into the
Knightdale USA. A greenway corridor is also shown connecting with the newly designated
Community Focus Area between Buffaloe Road and the future extension of Skycrest Drive.
Park Search Areas are shown on the Park and Greenway Plan map. A Community Park Search
Area and three Neighborhood Park search areas are recommended to serve the projected
population in the plan area.
Visual Resources Along U S 401
Visual resources should be emphasized in the 3000 foot corridor surrounding U.S. 401. The
purpose is to preserve and protect the historic, residential and rural atmosphere.
-Tree preservation is strongly encouraged along the corridor tIvrough rezoning or lands,. y T C- f

-Parking areas east of the Neuse River should be located at the side or rear of the building or
screened with landscaping so that a large expanse of asphalt is not visible from U.S. 401
-Appropriate S.H.O.D.s should be applied and maintained fhroug out this corri or----=
-Signs can either be attached to the building or be detached and low-profile. Signs should
complement the building style including scale, color and texture. Medium or high profile ground
signs should be limited to focus areas, with only one such ground sign for identification
permitted per development.

Bioretention 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 BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
- Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
- Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
- Heavy equipment will NEVER be driven over the bioretention cell.
- Special care will be taken to prevent sediment from entering the bioretention cell.
- Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month and within 24
hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
