stabilize for an entire growing season vegetation used for bank stabilization shall be limited to native woody species and should include establishment of a 30 foot wide wooded vegetated buffer on both sides of the relocated channel if possible A transitional phase incorporating fiber matting and seedling establishment is allowable Riprap may be allowed if it is necessary to maintain the physical integrity of the stream however the applicant must provide written justification and the calculations used to determine the extent of riprap coverage requested North Carolina Division of
