VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It maybe useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The ,.proposed residential
dormitory is part of the ECSU Campus Master Plan and is deemed necessary for supporting the
ECSU student population The proposed Wet Detention Pond is a SWM requirement associated
with the impervious surface area created by the proposed building. The (revised) SWM Permit
Application~ackage was submitted on December 27 2006approval expected) To avoid
stream and wetland impacts the proposed buildin~Land SWM pond are to be situated in upland
areas The SWM pond is sized to address all current and future development anticipated in the
14 2 acre drainage area Forebays of the SWM pond will be ig n the process of settling and
infiltration reducing_the flow into the main detention cell Volume and water quality will be
addressed further in the main cell of the pond The impacts are associated with the proposed
outlet structure and earthen overflow channel They have been engineered to further reduce
wetland impacts through velocity and flow attenuation see A-A and cross section on page 3 of 3
attachedLUpon completion the disturbed wetland area will be stabilized and revegetated to
reduce the erosion potential and further attenuate flow velocities. The proposed 4" PVC pipe to
be installed will facilitate the anticipated 2-day detention time thus effectively addressing water
quality as well as quantity impacts The project layout as shown will maximize the area of
undisturbed wetlands along the drainageway and will provide for onsite SWM treatment as per
County /State requirements The main purpose of the disturbance proposed here is to reduce
long-term downstream wetland impacts.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation. that maybe appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
