1. Avoidance and Minimization - The application describes "Area F" as "not
practical" and indicates that one (1) mile of new road construction would
be required to utilize this location. It appears that avoidance of a majority
of the proposed stream impacts would be possible by utilizing "Area F."
Please provide additional details as to why "Area F" is not an option.
2. Avoidance and Minimization - There appears to be significant
undeveloped property to the west of the current airport property boundary.
The purchase of additional property should be considered to avoid and
minimize proposed impacts. Please provide discussion of options
pertaining to acquiring property to avoid impacts to waters.
3. Avoidance and Minimization - "Impact #8" is proposed for construction of
a stormwater pond. The application indicates that City of Asheville (COA)
requirements related to construction in a floodway are forcing these
impacts to occur. Please provide documentation of any decision
communicated by the COA that confirms this statement. Additional
options to address stormwater management needs must be considered that
avoid "Impact #8."
4. Stormwater Management Plan (SMP) - Project approval is not possible
without documentation that a SMP has been approved by the COA.
5. Potential Mitigation - The stream located at the South-west corner of the
Airport Property (adjacent to NC HWY 280) is severely downeut and
heavily influenced by stormwater from the airport property. During the
onsite meeting (March 9, 2010), NCDWQ and NCWRC both expressed
that restoration / stabilization of this channel should be part of the
application package. No plans for this stream segment have been
submitted. A complete stream stabilization / restoration plan should be
developed and submitted for mitigation credit as part of this application.
