(a) Pursuant to section 34-0104(4) of the act, the commissioner must review the boundaries of each erosion hazard area 10 years from the date of its final identification and each 10 years thereafter.

(b) Pursuant to section 34-0104(4) of the act, the commissioner must also review the boundaries of erosion hazard areas after the occurrence of a major man-made or natural event or a major coastal storm. Coastal erosion hazard area maps will be revised if topographical changes or addition or loss of structural protection justify adjustment of the erosion hazard area boundary by 25 feet or more. Revised coastal erosion hazard area maps may not take effect until at least 12 months have elapsed from the occurrence of such event or such storm.

(c) In structural hazard areas, if shoreline recession has occurred at a rate sufficient to cause the receding edge to come within 25 feet of the erosion hazard area boundary in less than eight years from the most recent date of final identification of the erosion hazard area, a new recession rate analysis will be performed and the coastal erosion hazard area map will be revised accordingly without the 12-month delay specified in subdivision (b) of this section.

(d) In all cases of remapping revisions described in this section, the department must follow the procedures set forth in section 34-0104(2)-(4) of the act. The landowner notification process will be limited to only the owners of those properties affected by the proposed changes in the erosion hazard area by being added to or removed from the erosion hazard area or by a shift in the erosion hazard area boundary on a previously identified property.
