Re: Response to USFWS Request for Additional
Information
Silverstone
USACE AID: SAW-2017-02177
(Approx. 158.58 acres)
Wake County, North Carolina
On behalf of Cassa Knightdale II, LLC, we are providing a response to the Request for Additional
Information (RAI) email received on December 21, 2021 for Silverstone, an approximately 158.58-
acre site located southeast of the intersection of Hodge Road and Interstate 495 in Knightdale
within Wake County, North Carolina (the Site).
This project is currently covered under a Nationwide Permit (NWP) originally verified in June of
2020. Work has since initiated at the site and Impacts 2A/B and 3A/B (CWI-2.5 and CWI-2.7)
have been completed, while the remaining impacts are in progress. Mitigation credits were
purchased prior to impacts. Due to uncertainty in the project schedule, impacts 1 and 4A through
8 may not be complete by their respective permit expiration of March 15, 2022, when the current
permit extension period for NWP 29 expires. Therefore, this project was resubmitted for re -
permitting to enable continued coverage past the set expiration. It is anticipated that work will be
completed by March of 2023.
Note, impacts 9, 10A, and 10B (CWI-2.12 and CWI-2.13) are permitted under NWP 18, and are
anticipated to remain permitted under the 1-year extension of that permit until it expires February
25, 2023 (based on anticipated expiration dates at the time of this letter).
The proposed residential development will consist of 276 single-family lots, 103 townhomes, and
associated amenities including roadway, stormwater control measures (SCMs), and utility
improvements (i.e. public water supply and sanitary sewer alignment).
The proposed project requires the following impacts to jurisdictional features: three (3) road
crossings (two completed), ten (10) drainage impacts (two completed) for stormwater
conveyances which are designed to input treated surface water flow into jurisdictional features,
and four (4) temporary impacts for a 30-ft wide utility easement associated with gravity sewer line
crossings. These impacts require 0.044 acres of permanent wetland impacts, 0.024-acres of
ENGINEERING I DESIGN I TECHNOLOGY

temporary wetland impact, 283 linear feet and 0.025-acres of permanent stream impact, 103
linear feet and 0.021-acres of temporary stream impact, 88-ft of permanent — no loss stream
impact associate with velocity dissipator pads (per previous USFWS request), 32,877 square feet
of permanent Zone 1 buffer impacts, and 32,676 square feet of permanent Zone 2 buffer impacts.
Additional impacts to waters of the U.S. are not proposed. The proposed project is the final and
complete phase of the project with appropriate land use control measures in place for specific
areas which require them. Traditional equipment will be used consisting of front-end loaders,
bulldozers, paving equipment, graders, and earth movers.
All permanent stream impacts are associated with road crossings required for connecting the
southern and western portions of the site. Culverts were designed based on stream size and
anticipated flow requirements to ensure long term stability and aquatic life movement. Culvert
details, including the plan and profile, for each road crossing are included in the attached Impact
Maps. The proposed temporary utility impacts are required for the installation of the gravity sewer
line. The sewer line location was determined based on gravity sewer requirements in order to
connect to existing utilities and will require temporary impacts for installation through open cut. A
temporary pump -around system will be utilized during construction for Impacts 5B and 7B (see
attached plan and construction sequence). Upon completion of the temporary impacts, the
streambed will be restored to pre -project elevations and widths using natural streambed material.
The trench will be backfilled with the excavated natural streambed material to a depth of at least
12-inches or to bottom depth of impact area, whichever is shallower. Streambanks will be restored
to pre -project grade and contours.
Due to the proximity to the Neuse River former Impact 10A is now proposed as directional bore
to further reduce impacts, avoiding stream and buffer impacts in this location.
Stormwater outfalls with the proposed dissipator pads must be installed through the Neuse River
buffers due to the required length of culverts to adequately provide diffuse flow to the streams. If
the culvert lengths are shortened and a level spreader is placed downgradient, it cannot properly
diffuse the flow of water leaving the stormwater retention basins. Shortened culverts would lead
to channelization and erosion in and around the level spreader. Therefore, the current design is
required to prevent erosion and adequately move treated water from the stormwater retention
basin to the dissipator pad and into the streams. Buffer impacts will be limited to those required
for installation, as the culvert will be buried, and the area revegetated with herbaceous species
after installation.
Proper sedimentation and erosion control methods will be utilized during all phases of
construction and installation as described in accordance with the requirements of the North
Carolina Department of Environment and Natural Resources: Erosion Control Planning and
Design Manual (May 2013) and local codes. All work will take place during dry conditions and can
be facilitated from high, non -jurisdictional, stable ground. The contractor shall install silt fence,
inlet protection, sediment traps, division ditches, temporary coffer dams, tree protection, and
clearing only as necessary to install 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. The Erosion and Sediment Control plans for this project are currently not
complete. However, all of the plans will be reviewed by both Wake County and the Town of
Knightdale.

Temporary seeding and permanent seeding plans are included to restore impacted areas. The
project will meet all respective requirements of Best Management Practices and Engineered
Stormwater Control Structures as outlined through State and Local Stormwater Rules. Measures
will be taken to prevent oil, tar, trash, debris, and other pollutants from entering adjacent
jurisdictional features. Any excess excavated materials not utilized as back fill will be placed and
contained within upland areas and permanently stabilized to prevent erosion into adjacent
jurisdictional features. Therefore, stockpiling of excavated material within jurisdictional waters of
the U.S. will be strictly prohibited as part of the construction of this project. All project construction
activities initiated within jurisdictional waters of the U.S. will be carried to completion in an
expeditious manner to minimize the period of disturbance within jurisdictional waters.
Streams onsite vary from low flowing, small tributaries in the northeastern portion of the Site to
six to seven -foot -wide tributaries in the southcentral and southwestern portion of the Site. Streams
ranged from approximately 4-6 inches deep. The smaller tributaries consist of silt and sand
bottoms, with a lack of gravel and cobble (Page 1 — Photo 4; Page 1 and 2 — Photos 5, 6, 7, and
8; Page 2 — Photo 10). Many of these streams are low flowing or absent of flow. The larger
tributaries consist of silt and sand bottoms, with a moderate amount of gravel and cobble (Page
1 — Photos 1 and 2; Page 2 — Photo 9). These streams were observed to have higher rates of
flow than the smaller tributaries, but water quality is poor. There is not enough flow to maintain
clean, silt -free substrates and the water is murky in many areas. The main stream leading to the
eastern portion of the site and impacts 1, 2A/B, 3A/B, 4A/B, 5A/B, 6, and 7A/B/C formerly
contained a man-made pond with an earthen dam which appears to have been breached
sometime between 2005 and 2006.
The Carolina madtom prefers the riffles, runs and pools of medium to large streams and rivers
that have continuous, year-round flow and moderate gradient. This species prefers silt -free,
stable, gravel and cobble bottom habitat. The Atlantic pigtoe prefers small creeks to large rivers
with excellent water quality, with enough flow to maintain clean, silt -free substrates. The species
prefers coarse sand and gravel and is rarely in silt and detritus. The Neuse River waterdog prefers
streams with low to moderate gradient and low current velocity. The species needs clean, flowing
water with high dissolved oxygen concentrations. According to a current study being conducted
by NC State University student, Eric Teitsworth, on the Neuse River waterdog, the species has
not been located within the mainstem Neuse River by Teitsworth or his team. He has stated that
the Neuse River and other highly developed areas of Raleigh and Wake County no longer have
gravel and cobble bottoms, but they are all sand and silt. Based on the existing stream habitat, the
streams onsite do not constitute suitable habitat for the Carolina madtom, Atlantic pigtoe, and
Neuse River waterdog.
The dwarf wedgemussel is a generalist species, with high water quality preferred but not required.
No signs of mussels were observed throughout the streams on -site, including in areas with racoon
tracks on the depositional bars and benches throughout the streams with no sign of mussel shells.
According to available data the dwarf wedgemussel is believed to be extirpated within the Neuse
River and there are no known occurrences within the Poplar Creek-Neuse River Sub -watershed
(12-digit HUC 030202011103). The nearest watershed with known occurrences, Swift Creek,
intersects the Neuse River approximately 30 river miles south of the project area. The dwarf
wedgemussel is primarily listed due to impacts on habitat through water quality. Further, most on -
site impacts, 1 through 7, are located upstream of a recently removed earthen dam, making it
extremely unlikely any protected species would be located within this stream. Therefore, due to
the proposed sediment and erosion control plans to protect water quality, lack of high quality
habitat, recent presence of an earthen dam, and lack of observance of mussel species, it is the

opinion of Timmons that the proposed project may affect, but is not likely to adversely affect the
dwarf wedgemussel.
Please review the previously permitted Impact Maps and contact Lauren Norris -Heflin at (919)
866-4943 or [e-mail] if additional information is required.
