  • Change in NCDOT definition of "No-Rise"

    ​February 16, 2017 - Effective immediately, per NCFMP, NCDOT's definition of "No-Rise" (in Section 15.9 of the 2016 Guidelines) must be revised to no longer include up to a 0.1 ft. increase; rather, the "No-Rise" condition to qualify for a Type 1 MOA submittal must be no change in BFE (0.0 ft.) or a decrease of 0.1 ft. (rounded to tenth of foot).  An increase of 0.1 ft. or greater would require a CLOMR for projects in a Detailed Study.  In a Limited Detailed Study reach, an increase from 0.1 ft. to less than 0.5 ft. would now qualify as a Type 2d.  NCDOT Hydraulics is working on updating guidance on this.​
