application:
The site consists of the Lake Benson dam and its associated infrastructure. The
limit of disturbance in Zones 1 and 2 of the Neuse River buffer consists of
maintained herbaceous vegetation (lawn -type grass and weeds) associated with the
Lake Benson Dam. The limit of disturbance within Zones 1 and 2 of the Neuse River
buffer does not contain any woody vegetation (trees or shrubs). The project vicinity
mainly consists of residential developments; undeveloped, wooded land; and
farmland.

..................................................................................................
Provide a detailed description of the proposed activity including its purpose and include the type of equipment to be used:*
The purpose of the project is to perform upgrades and maintenance to existing

downstream of the Lake Benson dam. The project will install concrete bank
protection for the existing dam and a gravel access road. Equipment will include
mechanized equipment for clearing, concrete and other trucks for supplies and
construction materials.

disturbance will occur.
D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project. *
The project provides upgrades, repairs, and modifications to existing structures and
infrastructure. The limits of disturbance were reduced to the extent feasible to
minimize the footprint of the area of disturbance and to avoid the cutting of any
shrubs or trees within Zone 1 and Zone 2 of the Neuse River buffer.. Access to the
dam will be via a maintained corridor on an adjacent parcel such that the forested
area within and outside of the Swift Creek buffer zones immediately downstream of
the dam will not be impacted. Access to the dam from the adjacent parcel will be via
an existing maintained corridor; however, the existing corridor is narrow and will
require widening. The area of disturbance within the buffer has been reduced to the
extent feasible for the project to successfully meet its proposed purpose of
enhancing the dam's resilience to storm overtopping thereby reducing risk to public
safety.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The limits of disturbance will be clearly marked during construction activities and
Best Management Practices will be strictly enforced during all onsite activities.
E. Diffuse Flow Plan
1a. What type of SCM are you providing?*
r Level Spreader
r Vegetated Conveyance (lower SHWT)
F- Wetland Swale (higher SHWT)
V Proposed project will not create concentrated stormwater flow through the
buffer
r Other SCM that removed minimum of 30% nitrogen

1a. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land?
F Yes
r No
1b. If you answered "yes" to the above, does the project require preparation of an environmental document pursuant to the
requirements of the National or State (North Carolina) Environmental Policy Act (NEPA/SEPA)?
r Yes
F No
Violations
2a. Is the site in violation of DWR Wetland Rules (15A NCAC 02H .0500), Isolated Wetland Rules (15A NCAC 02H .1300), DWR
Surface Water or Wetland Standards, or Riparian Buffer Rules (15A NCAC 02B.0200)?
f Yes

The Benson Dam Improvement Project will not generate concentrated flow; therefore, no measures to
ensure diffuse flow are proposed. The post -construction condition of the buffer areas within the area of
disturbance will be similar to the existing condition in terms of stormwater flows through the buffer
area and into Lake Benson and Swift Creek.
