WETLAND /STREAM MAPPING: Symphony Lake is a perennial
waterbody depicted as Regency Lake on the USGS quadrangle (Figure 1).
Symphony Lake was constructed along unnamed tributaries to Swift Creek.
Stream features depicted on the Wake County Soils Survey were filled and /or
impounded for the construction Symphony Lake (Figure 2). These features
were likely impacted prior to the Neuse River Riparian Buffer Rules and NC
Division of Water Quality (DWQ) Water Quality Permitting Requirements.
DWQ has assigned Swift Creek, and its associated tributaries, a stream index
number of 27- 43 -(2.5) and a stream classification of Watersupply Watershed
(WS -III) and Nutrient Sensitive Waters (NSW). WS -III waters are protected for
water supplies, with permits required by local municipalities for nonpoint and
stormwater discharges. Symphony Lake is a perennial waterbody depicted as
Regency Lake on the USGS quadrangle (Figure 1, 3), therefore, it is subject to
the Neuse River Riparian Buffer Rules, as well the Town of Cary Urban
Transition Buffers. There is a 50 -foot wide Neuse River riparian buffer
adjacent to each side and an additional 50 -foot Urban Transition Buffer, from
the normal pool of Symphony Lake (Figures 1 -3). There are no jurisdictional
streams or wetlands within the project area and no stream or wetland impacts
associated with the proposed project (Figure 3 / Pies 1 -4).
PROJECT LOCATION/HABITAT: The proposed greenway re- alignment
is located along the western shoreline of Symphony Lake located off of
Regency Parkway, within Regency Park, in Cary, North Carolina. This is an
existing greenway which encircles Symphony Lake with a smooth asphalt trail
and skirts along the outdoor performance venue, Koka Booth Amphitheatre.
On the east end of Symphony Lake the trail connects to the Swift Creek
Greenway located just across Regency Parkway. Swift Creek
Greenway crosses through Hemlock Bluffs Nature Preserve connecting to
Ritter Park. The Symphony Lake greenway heads out to the west of the lake
across a flood plain and connects to an asphalt greenway that winds along the
western side of Regency Parkway finishing at Glade Park Road. Symphony
Lake is the home of the yearly Cary Road Race.
The riparian shoreline has been timbered over the past twenty years and is
sparsley forested with riparian canopies of Red Maple, Tulip Poplar, Sweet
uum, ironwooa ana a tew vaxs species, wttn an uncterstory Lnmese Trivet,
Baccharis, and fescue grasses. Land use within the vicinity of the project is

commercial, single and multi - family residential, recreational, and natural
forested areas along the perimeter of the project area.
PROPOSED PROJECTAMPACTS: The Town of Cary plans to replace an
existing 6 foot wide pedestrian bridge that currently spans the tailwater of
Symphony Lake and re -align the greenway trail in this section, at the western
side of Symphony Lake. The 10 -foot asphalt trail currently makes a 90-
degree turn onto and off the existing 6 -foot wide bridge, which is an unsafe
bottleneck for pedestrians and runners on this portion of the greenway. There
is potential for injury either side of the current bridge's 90- degree turns during
road races which routinely take place at this along this portion of the Town's
greenway system. The Town plans to replace an existing 6 foot wide
pedestrian bridge with a 12 -foot wide bridge and re -align the 10 -foot wide
asphalt trail, approximately 20 -feet downstream (to the west) in order to line
up with the existing greenway on the north side of the lake.. This proposal
will take out the 90- degree turns and provide a safer entrance and exit for
pedestrians and runners to access the new 12 foot wide bridge. The existing
bridge and existing trail in this section will be removed once the new bridge is
constructed.
The project area runs perpendicular and parallel to the shoreline of Symphony
Lake, a tributary to Swift Creek, a tributary within the Neuse River basin.
Symphony (Regency) Lake is a perennial waterbody depicted on the USGS
quad, therefore, it is subject to the Neuse River Riparian Buffer Rules. The
proposed greenway re- alignment impacts Zone 1 and Zone 2 in several
locations, and crosses the tailwater at the head on the western side of the lake.
(Figure 4). It will tie into an existing Town of Cary greenway system on the
north and south (Figure 4 — Pies 1 -4). There are no impacts which require
written 404/401 permits, however, we are requesting authorization for impacts
to the Neuse Buffer, totaling 6,309 square feet (sf) (Figure 4 — Inset 1). There
are a total of 4,885 sf of impacts to Zone 1, of which 548 sf is new impervious
surface, 3,948 sf is associated with grading, and 389 sf is temporary impacts
associated with removal of existing trail to the west. There are a total of 2,361
sf of impacts within Zone 2, of which 443 square feet is new impervious and
1,918 sf are grading impacts. All impacts are deemed "Allowable" under the

The bridge is proposed to be relocated approximately 20 -feet downstream (to
the west) in order to line up with the current greenway on the north side. The
bridge will be wooden slatted and supported with steel beams, spanning the
entire width of the lake in this location and placed on footers at the shoreline
within Zone 1. The asphalt greenway is proposed to be 10 feet in width
throughout the project, with a wider transition area onto the bridge located on
the southern side. The gradient is low to flat in the location of the project and
the greenway will be slightly crowned to allow for drainage to slope off on
both sides of the greenway and diffuse the flow into the lake. There are no
jurisdictional streams or wetlands within the project area and no stream or
wetland impacts associated with the proposed project (Figure 4 / Pics 1 -4)
Typical construction equipment will be used such as a long -arm track -hoe,
front end loader, for the initial The bridge will be constructed using a long
arm track hoe and manual labor, utilizing logging mats along the shoreline to
curb erosion.

1) The greenway is proposed to cross at the head of the lake (Figure 4-
Area 5) using a wooden slatted bridge supported by steel beams and
cross an approximate 90- degree angle. Using steel beams allows for a
longer span length without the need for pile supports, which avoids
direct impacts to Symphony Lake.
2) The bridge was re- aligned downstream (to the west) in order to line up
with the existing greenway on the north side. This alignment avoids
upstream wetlands and reduced the need for more impervious surface
impacts.
DIFFUSE FLOW: The project is within a section of existing greenway and
the gradient is low to flat in the location of the project. The greenway will be
slightly crowned to allow for drainage to slope off on both sides of the
greenway and diffuse the flow through the grassed buffer areas before it enters
into the lake.
MITIGATION: All buffer impacts are deemed "Allowable" under the Neuse
River Riparian Buffer Rules — Table of Uses, therefore no mitigation is
proposed.
Consideration of this project is greatly appreciated. If you should have any
questions or require additional information, please do not hesitate to contact

3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The proposed Town of Cary greenway re- alignment is located along the western shoreline of Symphony Lake
located off of Regency Parkway, within Regency Park, in Cary, North Carolina. This is an existing
greenway which encircles Symphony Lake with a smooth asphalt trail and skirts along the outdoor
performance venue, Koka Booth Amphitheatre. On the east end of Symphony Lake the trail connects to the
Swift Creek Greenway located just across Regency Parkway. Swift Creek Greenway crosses through
Hemlock Bluffs Nature Preserve connecting to Ritter Park. The Symphony Lake greenway heads out to the
west of the lake across a flood plain and connects to an asphalt greenway that winds along the western side of
Regency Parkway finishing at Glade Park Road. Symphony Lake is the home of the yearly Cary Road Race.
Symphony Lake was constructed along an unnamed tributaries to Swift Creek. Stream features depicted on
the Wake County Soils Survey were filled and /or impounded for the construction Symphony Lake. These
features were likely impacted prior to the Neuse River Riparian Buffer Rules and NC Division of Water
Quality (DWQ) Water Quality Permitting Requirements. DWQ has assigned Swift Creek, and its associated
tributaries, a stream index number of 27- 43 -(2.5) and a stream classification of Watersupply Watershed (WS -III)
and Nutrient Sensitive Waters (NSW). WS -I1I waters are protected for water supplies, with permits required by
local municipalities for nonpoint and stormwater discharges. Symphony Lake is a perennial waterbody
depicted as Regency Lake on the USGS quadrangle (Figure 1, 3), therefore, it is subject to the Neuse River
Riparian Buffer Rules, as well the Town of Cary Urban Transition Buffers. There is a 50 -foot wide Neuse
River riparian buffer adjacent to each side and an additional 50 -foot Urban Transition Buffer, from the normal
pool of Symphony Lake (Figures 1 -3).
The riparian shoreline has been timbered over the past twenty years and is sparsley forested with riparian
canopies of Red Maple, Tulip Poplar, Sweet Gum, Ironwood and a few Oaks species, with an understory
Chinese Privet, Baccharis, and fescue grasses. Land use within the vicinity of the project is commercial,
single and multi- family residential, recreational, and natural forested areas along the perimeter of the project
area.
3b. List the total estimated acreage of all existing wetlands on the property:
While there are wetlands within the tailwater of the lake, there are no wetlands within project area.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Original stream impounded to form Symphony Lake, but there are no streams within project area.
3d. Explain the purpose of the proposed project:
The purpose of this project is to re -align a greenway to service the residents of Cary and Wake County, NC.

3e. Describe the overall project in detail, including the type of equipment to be used:
The Town of Cary plans to replace an existing 6 foot wide pedestrian bridge that currently spans the tailwater
of Symphony Lake and re -align the greenway trail in this section, at the western side of Symphony Lake.
The 10 -foot asphalt trail currently makes a 90- degree turn onto and off the existing 6 -foot wide bridge, which
is an unsafe bottleneck for pedestrians and runners on this portion of the greenway. There is potential for
injury either side of the current bridge's 90- degree turns during road races which routinely take place at this
along this portion of the Town's greenway system. The Town plans to replace an existing 6 foot wide
pedestrian bridge with a 12 -foot wide bridge and re -align the 10 -foot wide asphalt trail, approximately 20 -feet
downstream (to the west) in order to line up with the existing greenway on the north side of the lake.. This
proposal will take out the 90- degree turns and provide a safer entrance and exit for pedestrians and runners to
access the new 12 foot wide bridge. The existing bridge and existing trail in this section will be removed
once the new bridge is constructed.
The project area runs perpendicular and parallel to the shoreline of Symphony Lake, a tributary to Swift
Creek, a tributary within the Neuse River basin. Symphony (Regency) Lake is a perennial waterbody
depicted on the USGS quad, therefore, it is subject to the Neuse River Riparian Buffer Rules. The proposed
greenway re- alignment impacts Zone 1 and Zone 2 in several locations, and crosses the tailwater at the head
on the western side of the lake. (Figure 4). It will tie into an existing Town of Cary greenway system on the
north and south (Figure 4 — Pics 1 -4). There are no impacts which require written 404/401 permits, however,
we are requesting authorization for impacts to the Neuse Buffer, totaling 6,309 square feet (sf) (Figure 4 —
Inset 1). There are a total of 4,885 sf of impacts to Zone 1, of which 548 sf is new impervious surface, 3,948
sf is associated with grading, and 389 sf is temporary impacts associated with removal of existing trail to the
west. There are a total of 2,361 sf of impacts within Zone 2, of which 443 square feet is new impervious and
1,918 sf are grading impacts. All impacts are deemed "Allowable" under the Neuse River Riparian Buffer
Rules — Table of Uses.
The bridge is proposed to be relocated approximately 20 -feet downstream (to the west) in order to line up
with the current greenway on the north side. The bridge will be wooden slatted and supported with steel
beams, spanning the entire width of the lake in this location and placed on footers at the shoreline within Zone
1. The asphalt greenway is proposed to be 10 feet in width throughout the project, with a wider transition area
onto the bridge located on the southern side. The gradient is low to flat in the location of the project and the
greenway will be slightly crowned to allow for drainage to slope off on both sides of the greenway and
diffuse the flow into the lake. There are no jurisdictional streams or wetlands within the project area and no
stream or wetland impacts associated with the proposed project (Figure 4 / Pics 1 -4)
Typical construction equipment will be used such as a long -arm track -hoe, front end loader, for the initial
The bridge will be constructed using a long arm track hoe and manual labor, utilizing logging mats along the
shoreline to curb erosion.

D. Impact Justification and Mitigation
1 1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
A re- alignment which runs on high ground, parallel to the normal pool of Symphony Lake, and uses the
existing greenway has been chosen to avoid and minimize impacts to the Neuse River Buffer, and aquatic
resources.
1) The greenway is proposed to cross at the head of the lake (Figure 4 -Area 5) using a wooden slatted
bridge supported by steel beams and cross an approximate 90- degree angle. Using steel beams allows
for a longer span length without the need for pile supports, which avoids direct impacts to Symphony
Lake.
2) The bridge was re- aligned downstream (to the west) in order to line up with the existing greenway on
the north side. This alignment avoids upstream wetlands and reduced the need for more impervious
surface impacts.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
-To minimize damage to existing trees, tree protection fence shall be maintained on the site until all site
work is completed and the final site inspection is scheduled.
- Streets in front of the project will be kept clean at all times or a wash station will be required
- The project will meet all relative requirements of Best Management Practices and Engineered
Stormwater Control Structures as outlined in the Town of Cary UDO (chp. 7, part 3.7).
- All slopes 2:1 and steeper shall be stabilized with permanent slope retention devices or suitable
combination of planting and retention devices. All slopes greater than 3:1 will require biodegradable
erosion control matting with a minimum 2 year life.
- 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. Sediment fences shall be inspected at least once a week
and after each rainfall.
- Proper sedimentation and erosion control methods will be utilized during all phases of construction and
installation as described in the Erosion Control Plan sheets to be reviewed and approved by the NC
Division of Land Quality. All work will take place during dry conditions and can be facilitated from
high, non jurisdictional, stable ground adjacent to the shoreline. The contractor shall install silt fence,
these devices. An erosion control inspections report is required and will be kept by the owner's
representative.
