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
Swift Creek in the project vicinity has a mostly forested floodplam on both sides The property south of the creek is Hemlock
Bluffs Nature Preserve a state owned natural area managed by Cary Parks & Rec A boardwalk trail runs alongside the south
stream bank where ongoing stream bank erosion in the proposed restoration area (outer bend) threatens to undermine the trail
Steep bluffs border the creek just upstream of the eroding area supporting a disjunct population of EasternHemlock North of
Swift Creek is Harold Ritter Park which includes a paved greenway trail along the Swift Creek floodplam and ballfields and
playground facilities in the uplands Access into Ritter Park is from West Lochmere Drive north of the park A residential
neighborhood is located east of the Ritter Park parking lot which will be used for construction access and staging area A
perennial tributary flows southward immediately west of the parking lot The proposed construction access corridor will cross
this tributary near the southwest corner of the parking lot proceed southward along the west side of the tributary (east of the
baseball field) cross the greenway trail and continue southward to the gently sloping north bank of Swift Creek
3b List the total estimated acreage of all existing wetlands on the property
RJG &A found no jurisdictional wetland in the project study area (26 Jan 2011) which encompasses approximately three acres
extending from the Ritter Park parking lot southward to the restoration area on Swift Creek The floodplam along Swift Creek
and its tributary is mapped as Chewacla soils which often have hydric inclusions but the areas examined in the study corridor
appeared sufficiently well drained and exhibited high soil chroma indicative of non wetlands Other portions of the Ritter Park
and Hemlock Bluffs parcels beyond the three acre project area were not examined and may contain unmapped wetlands
3c List the total estimated linear feet of all existing streams (intermittent and perennial) on the property
The southern boundary of Ritter Park (PIN #0761495669) has approximately 1100 feet of frontage along Swift Creek
Tributary SCT 1 (perennial) flows approximately 800 feet from the parking lot area southward into Swift Creek Tributary SCT
3 (intermittent) flows approximately 400 feet eastward across the Swift Creek floodplam into SCT 1 SCT 1 is mapped on the
USDA Soil Survey of Wake County (sheet 67) and SCT 3 is not mapped Two other unmapped channels were field evaluated
(SCT 2 and SCT 4) and determined to be ephemeral using NC DWQ criteria The USGS quadrangle (Apex) depicts Swift
Creek but does not map any of these tributaries

PCN Form — Version 1 3 Dec 2008

3d Explain the purpose of the proposed project
Large storms over the past decade have eroded and undercut the south bank (outer bend) of Swift Creek on the Hemlock Bluffs
Nature Preserve property This erosion has undercut and toppled several trees along the bank and is encroaching toward the
boardwalk trail from which visitors view these scenic and ecologically unique bluffs Stream bank repair using natural channel
design methods is proposed to stabilize the channel reduce further aquatic habitat damage and protect the trail Todd St John
a natural stream restoration expert at Kin-ley Horn Associates designed the proposed stream bank repair using rock and soil fill
to re grade the eroding bank log vane structures to divert erosive energy away from the bank and live stakes cuttings and trees
planted to re vegetate both the south and north stream banks Undercut voids beneath standing trees on the south bank will be
carefully filled to save these trees and additional trees and shrubs planted to create a dense woody root network to resist erosion
3e Describe the overall project in detail including the type of equipment to be used
Access to the project construction area will be from the parking lot in Harold Ritter Park east of the baseball field 800 feet north
of Swift Creek Access from the north will avoid impacts to the steep slopes and mature forest community (including hemlocks)
in the State Natural Area south of the creek The stream bank slope is more gradual on the north bank (inner bend) which will
facilitate getting equipment in and out of the creek with minimal damage Because the in stream portion of construction will
require only about 2 days it will be conducted without dewaternng the stream In stream work will be scheduled during a period
when stream flow is low and negligible rainfall is forecast
The contractor will install erosion control measures and tree protection fencing as shown on the plans by Kimley Horn
Associates (KHA) From the parking lot south to the greenway trail (450 feet) there is an existing cleared corridor along the
west bank of tributary SCT 1 (east of the baseball field) and little or no tree removal will occur in the northern half of the access
corridor SCT 1 (perennial 8 to 10 ft wide) will be crossed near the southwest corner of the parking lot using mud mats
constructed of 8 x 8 inch hardwood timbers laid in the stream There is an existing gap in the riparian forest at the proposed
crossing and no forest clearing or temporary earth fill or grading in the creek is necessary in this area From the greenway trail
southward to Swift Creek a 350 foot long 15 foot wide access trail through the floodplam forest will be cleared The proposed
corridor was selected and flagged to avoid and nummize damage to larger trees Only a few trees larger than 6 inch dbh will be
cut Timber mud mats will be used to cross tributary SCT 3 (intermittent 5 to 8 feet wide) along this segment but no other
temporary fill or grading in SCT 3 is necessary Five larger trees (10 to 24 inch ash and birch) along the north bank of Swift
Creek near the end of the access road will be cut with chamsaws and used in the channel repair structures Live stumps will be
left in place to resprout
Approximately 130 linear feet of the north (left) stream bank will be graded with a backhoe to approximately 3 1 slope from the
floodplam (elev 318 ft) to the toe of bank (elev 312 ft) to provide a stable channel cross section and to facilitate equipment
access into the creek Soil removed will be used in restoring the opposite bank The graded bank will be covered in coir fiber
matting and anchored with wooden stakes Live stakes of willow and silky dogwood will be installed on the slope and tree
seedlings and a few larger trees planted along the top of bank A path for backhoe access into the stream will be left bare until
the south bank work is completed and the backhoe removed then this final stream bank area will be planted
Along the south (right) bank approximately 120 linear feet of undercut bank will be filled with a mix of Class A and B nprap
carefully placing material around exposed tree roots to avoid damage to trees and shrubs on the overhanging bank Once this
void area is filled a 1 ft thick x 5 ft wide (nnmmum) footer of nprap and #57 stone wrapped in geotextile filter fabric will be
installed and staked along the edge of the rock filled area new stream bank A series of 1 ft thick soil lifts wrapped in coir fiber
matting will be stacked atop the geotextile footing and overlapped to achieve a 1 1 bank slope from the toe footing up to the top
of bank approximately six feet high Live branch cuttings will be placed horizontally between the lifts and live stakes installed
through the coir mesh
Two log vanes will be constructed in the channel bed against the south bank using trees cut from the north bank and large
supporting rocks obtained from a quarry A backhoe with a thumb will be used for positioning these rocks and logs and a
small scour pool excavated dust downstream of each log vane These structures will divert erosive energy away from the stream
bank toward the center of the channel An additional 60 feet of stream bank upstream will also be graded coir matted and live
staked for a total right bank impact length of approximately 180 ft

grassed (when Ritter Park was developed) it will not involve any new impact to the riparian buffer SCT 3 is an unmapped stream
and is not subject to Neuse Buffer Rules
D Impact Justification and Mitigation
1 Avoidance and Minimization
1a Specifically describe measures taken to avoid or minimize the proposed impacts in designing project
The temporary access corridor was selected by Town of Cary and RJG &A staff to avoid and minimize impacts to streams forested
riparian buffers and mature trees Trees to be removed along the access corridor are mostly less than 6 inches dbh The five larger
trees near the north bank of Swift Creek will be cut with a chainsaw (stumps left) and their trunks used to build the log vane
structures No.junsdictional wetlands occur in the project area Timber mats used for stream crossings and in stream construction
will preclude the need for temporary fill and culverts The proposed natural channel design fits the stream s hydrologic and
sediment transport needs providing a geomorphically stable channel compatible with its location in a nature preserve
1b 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 Timber mud
mats will be used for the two temporary stream crossings and in stream construction work Because the in stream portion of
construction in Swift Creek will require only about 2 days and Swift Creek is shallow in this area the KHA designers chose not to
dewater the work area with temporary coffer dams and pumping Aquatic life will not be stranded on a dry creek bed In stream
work will be scheduled when stream flow is low and negligible rainfall is forecast Stream banks will be promptly revegetated
upon completion of the stream bank grading work

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 Michaux s Sumac There is no suitable habitat in the project vicinity for Red cockaded Woodpecker (extensive
mature pine dominated forest) nor for Michaux s Sumac (open edges of oak hickory forests or thin canopy woodlands) and no
recent or historic records of these species within three miles of the project area Based on lack of suitable habitat and lack of nearby
records the project is not likely to affect Red cockaded Woodpecker or Michaux s Sumac Swift Creek may be suitable habtat for
Dwarf Wedgemussel and there are records of this mussel in the lower Swift Creek watershed in Johnston County However it has
never been reported in the Swift Creek watershed upstream of Lake Benson (approx ten miles downstream from Hemlock Bluffs)
and several mussel surveys in Swift Creek over the past 20 years have failed to find Dwarf Wedgemussel upstream of Lake Benson
Based on these prior mussel surveys the project is not likely to affect Dwarf Wedgemussel or its occupied habitat
6 Essential Fish Habitat (Corps Requirement)
6a Will this project occur in or near an area designated as essential fish habitat?
❑ Yes ® No
6b What data sources did you use to determine whether your site would impact Essential Fish Habitat?

7 Historic or Prehistoric Cultural Resources (Corps Requirement)
7a Will this project occur in or near an area that the state federal or tribal
governments have designated as having historic or cultural preservation
status (e g National Historic Trust designation or properties significant in
❑ Yes ® No
North Carolina history and archaeology)?
7b What data sources did you use to determine whether your site would impact historic or archeological resources?
The GIS database of archaeological and historic site locations provided by SHPO does not include any mapped resources in the
project vicinity No man made structures greater than 50 years old occur in the project area Temporary clearing for the
construction access road on the Swift Creek floodplam will not require any excavation or fill and any buried cultural artifacts
that might be present will not be disturbed The areas where excavation or fill will occur are on the stream banks where
significant cultural artifacts are unlikely to be preserved
8 Flood Zone Designation (Corps Requirement)
8a Will this project occur in a FEMA designated 100 year floodplain?
® Yes ❑ No
