Attachments:Yanbrg16NC197ElkFk2016-02.docx; Re: splitting the base flow of a stream
The proposed project splits the base flow of the river into 2 barrels. This practice has been rejected in recent years in Merger
and other projects. Attached are comments on another project (in Yancey Co. in 2016) where concerns about this practice were
voiced and a brief literature review (mainly FHWA publications) was provided. Also attached is an email conversation from 2014
where I indicated my concerns, making sure I wasn’t over-reaching, and Marella’s reply with her thoughts on it. I received a
couple other brief replies in agreement, but received no disagreement. I’m not sure why the news that this practice is
inappropriate has not gotten out to all those that design waterway crossings, but we need to try to correct that.
I believe a redesign is needed for this project in order to minimize impacts; to maintain the natural dimension, pattern and
profile of the waterway through the crossing; and to avoid the negative impacts that can occur from splitting the base flow of
the river. If a formal letter to this effect specifically for this project is needed, I will be glad to provide one.
