    Change in NCDOT definition of "No-Rise"

    Effective immediately (as of 2/16/17), 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.

    2016 Guidelines

    All MOAs submitted on or after 11/21/2016 will need to follow the 2016 Guidelines for Drainage Studies and Hydraulic Design. One of the biggest changes concerning MOAs is the rounding of Base Flood Elevations; BFEs must be rounded to the tenth and then compared.  (see Guidelines Chapter 15, Section 15.9). Also, all water surface elevations (including the 100-year) are to be reported to the tenth of a foot in the BSR or CSR (see Guidelines Chapter 8, Section 8.8).

    Use of HEC-RAS 5.0 and up

    December 07, 2016 - HEC-RAS 5.0 and up will not be accepted for use on NCDOT projects until further notice.  Until notified, continue to use HEC-RAS 4.1 (3.1.1 or higher is acceptable).
