Re: PCN for Oakwood North Subdivision, Raleigh, Wake County ( Neuse River basin).
Dear US -ACE and NC -DWQ staff:
Attached is the PCN (NWP -29) for KB Home's proposed Oakwood North Neighborhood, a 39-
lot urban infill subdivision located on a 10.77 acre parcel 1.5 mile northeast of the State Capitol
in Raleigh. The proposed road through the new subdivision will connect the dead -end stub of
Plainview Ave to the north with North State Street to the south, and will cross one intermittent
stream and its riparian buffer along the northern edge of the property. Martin Richmond of
DWQ verified the ephemeral/intermittent transition point on 28 Sept 2012. The stream crossing
location is constrained by the location of Plainview Ave and existing homes on both sides.
The road crossing will require 72 linear feet of this stream to be piped (average 5 ft wide) and 46
linear feet of stream to be stabilized with rip -rap (average 8 ft wide). Most of the riparian area
north of the stream is previously disturbed by the existing street, homes and lawns which pre-
date the Neuse Buffer Rules. The total permanent buffer impacts (mostly south of the stream)
are 2845 sq.ft in zone 1 and 1674 sq.ft. in zone 2. The total temporary impacts are 2756 sq.ft in
zone 1 and 2244 sq.ft. in zone 2.
Another stream south of the project site is more than 60 feet beyond the property boundary and
neither the stream nor its buffer will not be affected. The drainage divide between the two
streams lies in an east -west orientation through the middle of the property. Both streams flow
westward into Cemetery Branch, which flows into Pigeon House Branch and then to Crabtree
Creek, all of which are designated Class C -NSW waters. No wetlands exist on the property,
based on my field evaluation in September 2012. Two stormwater detention basins, one in the
northwest corner of the site and one in the southwest corner, are presently under review by City
of Raleigh which has delegated authority for stormwater permitting.

3. Project Description
3a. Describe the existing conditions on the site and general land use in the vicinity of the project at time of this application:
The 10.77 acre project site is mostly wooded except for one acre in the center containing a vacant single- family home. The
main access to the property (dirt driveway to the house) is from the north end of North State Street along the southern
property boundary. Plainview Ave ends at the northern property boundary, but there is no existing road onto the site from
the north. Single - family residential lots border the property along the south (Edmund St), east (Weatherford Cir), and north
(Plainview Ave). Conn Elementary School borders the property along the west, and St. Matthew AME Church borders the
northeast corner of the property. A headwater stream originates near the northeast property corner and flows west -
northwest across the northern edge of the property. Another stream originates behind the homes along Edmund Street and
flows westward roughly parallel to and about 60 to 80 feet south of the property. Both streams flow into Cemetery Branch
0.2 mile west of the property, which in turn flows into Pigeon House Branch and then into Crabtree Creek.
Page 2 of 10
PCN Form — Version 1.3 Dec 2008

3b. List the total estimated acreage of all existing wetlands on the property:
RJG &A Environmental Consultants examined the property for streams and wetlands during August 2012, and found no
jurisdictional or isolated wetlands on or immediately adjacent the property.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
An unnamed tributary of Cemetery Branch originates on the northeast portion of the property and flows westward 255 feet
across and along the northern edge of the property. It continues as an ephemeral channel upslope (east) of the intermittent
stream head for 110 feet to the eastern property line, then off -site onto the church property. This northern stream drains the
northern half of the property. A second stream which drains the southern half of the property is located more than 60 feet
beyond the southern property boundary. These two streams are mapped on the USDA Soil Survey of Wake County sheet
49 (1970), but are not mapped on the USGS Topographic Quadrangle "Raleigh East."
3d. Explain the purpose of the proposed project:
The project will provide 39 small residential lots in one of Raleigh's older neighborhoods, with convenient access to schools
and parks. It will also provide a street connection between North State Street to the south and Plainview Ave to the north,
both of which end at the property line. Most of the riparian buffer along the northern portion of the property plus some
additional lands will be preserved as woodland, and stormwater basins near the northwest and southwest corners of the
property will be used to control runoff volume and quality.
3e. Describe the overall project in detail, including the type of equipment to be used:
The Oakwood North project is a single family neighborhood to be constructed in three phases. Access for site clearing,
grading and construction will be from North State Street on the south side of the property, leaving the stream and riparian buffer
along the north edge of the property undisturbed until the final phase when the road crossing to Plainview Ave is built. This
stream crossing is required by the City of Raleigh to provide traffic connectivity. The existing abandoned house will be
removed, and most of the property will be cleared and graded for the proposed roads, utility lines, housing lots, and two
stormwater basins. The northeastern portion adjacent to the stream buffer will be preserved as forest.
The two stormwater BMPs will be constructed as dry detention basins for water quantity control. The outlet of the
southern basin will use a level spreader for diffuse flow outside the buffer, and the northern basin outlet will tie directly into the
culvert at the road crossing. The proposed stream crossing at the existing southern end of Plainview Ave will impact 118 feet of
stream using 72 linear feet of 42" culvert and 46 linear feet of riprap at the culvert outlet. The road crossing and culvert will
use segmental block walls to minimize the length of impact to the stream and buffers. Maintained easements alongside the
culvert are required by the City for maintenance access to the culvert ends and headwalls.

Section D. Impact Justification and Mitigation
1 1. Avoidance and Minimization I
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The stream and buffer crossing at the north edge of the site will be as close to perpendicular as possible, given the existing
alignment of Plainview Ave. The off -site southern tributary is more than 60 feet beyond the property and will not be affected.
Both stormwater basins will be outside of riparian buffers. Additional riparian land along the ephemeral channel upstream of the
intermittent stream head (northeast corner of the property) will be included in the tree preservation area. Retaining walls at the
culvert ends will minimize the width of fill required for the road, and disturbance limits will be 3 feet beyond the retaining walls as
required by City of Raleigh for maintenance easements.
Page 5 of 10
PCN Form —Version 1.3 Dec 2008

1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Erosion and sediment controls and tree protection fencing will be installed at the beginning of project construction. Construction
access will be from North State Street at the south edge of the property, so that disturbance of the stream and riparian buffer at the
north edge can be delayed until the final phase after the rest of the cleared areas (roadways, house lots and stormwater basins) are
stabilized and reseeded. This approach along with efficient construction time management will minimize exposure of the stream to
erosion and sediment. Poured concrete will be isolated from stream water during curing to prevent release of toxic substances into
adjacent waters.

® Yes ❑ No
impacts?
® Raleigh
5c. If yes, indicate the USFWS Field Office you have contacted.
❑ Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
US -FWS and NC -NHP websites list three federally endangered species in Wake County: Dwarf Wedgemussel, Red - cockaded
Woodpecker, and Michuax's Sumac. The urban- impacted intermittent streams on and adjacent to the Oakwood North project site
do not provide suitable habitat for Dwarf Wedgemussel, which requires perennial flow, good water quality, and relatively stable
stream -banks and bed materials. There is no record of Dwarf Wedgemussel in the Pigeon House Creek or Crabtree Creek
watersheds. Red - cockaded Woodpecker requires large tracts (typically 100 acres or more) of mature pine- dominated forest with
sparse hardwood understory encroachment. Some mature pines exist on the site, but this small patch is too isolated from largerpine
stands to provide suitable habitat for these woodpeckers. Michaux' Sumac occurs in thin - canopy woodlands and along forest edges
that receive abundant sunlight, including scrubby road embankments and powerline rights -of way. None of these habitat types occur
on the project site, and none of these three endangered species has been reported within five miles of the project site. As dense
urban development surrounds this 10.7 -acre parcel on all sides, none of these species is likely to occur on adjacent lands. Based on
lack of suitable habitat and lack of nearby records for these three species (NC -NHP and NC -WRC records), biologist Gerald Pottern
