V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
NCG520000 Application #8 should read as noted in Staff Report #3. (Lower Creek, Class Q.
A map was not submitted with the NCG520000 Application. A map associated with a Mine Permit Application
was erroneously attached. This map is not sufficient. ARO staff have included an accurate map of this site for
coverage under COC NCG520124.
Inspection Notes:
Amy Annino and Tim Heim visited the site and with Mr. Hoffman, staff observed bank erosion in an outside meander
bend at the proposed dredge site. Mr. Hoffman indicated that he will be stabilizing the stream bank by grading the
bank (working above the ordinary high-water line) and establishing native vegetation. Also, Lower Creek could be
used as a navigable waterway by recreational canoe / kayaks. Staff informed Mr. Hoffman that signage must be
posted upstream and downstream of the sand dredge to warn individuals using the river for recreational purposes.
