Erosion crisis raises urgent questions on coastal management

In a recent government meeting, discussions centered around the impact of geotubes and core terraces on coastal erosion, particularly in relation to bluff volumes. Dr. Bridal presented findings indicating significant changes in bluff erosion, noting that while geotubes are not solely responsible for the erosion observed, they do appear to influence the dynamics of sand movement along the coastline.

Dr. Bridal highlighted that the area is predominantly erosional, with increased erosion noted on the down-drift or northern side of the bluff. His analysis suggested that the geotubes and core terraces are trapping sand, which may hinder its natural flow to other areas of the beach. He urged the commission to consider these findings seriously, particularly regarding failure criteria and the necessity for mitigation measures.

Following Dr. Bridal's presentation, the chair opened the floor for public comments, indicating that further discussions would include insights from Chip Nylund, who was expected to address the context of a recent submission from his office to the conservation commission. The meeting underscored the ongoing concerns about coastal management and the implications of current erosion control measures.
