Subject: Comments on PCN and Stream Restoration Plan -Blockhouse Creek -Polk County.
Baker Engineering plan for EEP; EEP Full-Delivery Project?? (DWQ# 20071890)
The plan generally looks OK except for significant areas where the buffer is shown as less than
50 feet on one side of the stream. Section 5.8.1 of the plan states that buffers from 30 to 50 feet
will be established. Again, Baker and NCEEP need to understand that they may not get full credit
for stream length in sections where buffers are not 50 feet.
The only additional item is they are proposing to use black walnut as one of the primary tree
species. I sent a e-mail to Karen Hall at NCSU asking her opinion on the use of black walnut, as
it is allopathic to other plant species, and may hinder good vegetation growth around these trees.
